SWIVEL MODULE FOR SOLAR ENERGY PRODUCTION

field of the invention

The invention relates to a swivel module comprising at least one connection flange body and one swivel flange body, a system comprising the swivel module according to the invention and a solar system comprising the system according to the invention.

representation of the invention

The subject of the invention is an overall unit, here called a swivel module, consisting among other things of two rotatably connected receiving bodies that can be rotated relative to each other via a gear unit. The receiving bodies have flange connections. A distinction is made between a receiving body, here called a connection flange body, which is mounted on a boom, and a swivel flange body, which is rotatably mounted on the receiving flange body. The entire device serves to move solar collectors from the open state to the closed state and vice versa. In the open state, four collector units, each consisting of a collector and a holding arm, are arranged in a star shape, for example. The swivel module now makes it possible to close an inner collector pair with an outer collector pair. This is done by swiveling the outer collector pair by 180° from the open to the closed state. The inner collector pair comprises a first and a third energy module, which are fixedly attached to the connection flange body. The outer collector pair comprises a second and a third energy module, which are mounted on the swivel flange body.

One object of the invention is to connect the electrical cables and the hydraulic lines from the boom and the support arms in addition to the force-fitting assembly of the collector units. Further objects of the invention emerge from the following explanations.

For the outer collectors, the pipes and electrical cables can be routed via a rotary axis according to the invention. In addition to the supply and return pipes for the flow of the heat transfer medium, a pipe for the flow of cleaning water is also provided. Here, too, a connection of the piping from the boom to the holding arms of the inner collector pair is required. Mechanical stops should precisely specify the end positions, open and closed. Expansion compensators can compensate for the thermal expansion of the piping from the boom and the holding arms. The piping in the swivel module can be thermally insulated. Thermal bridges should be prevented. The entire mechanism can be completely sealed so that any damaging environmental influences are kept away.

Another task is to create a compact delivery unit. This means that assembly in the field should only require a minimum of effort and incorrect assembly should not be technically possible (e.g. different plugs and terminal connections). When assembling the collector units, there is no distinction between left, right, inner or outer collector units. These are identical parts and the flow direction will always be correct. The system is modular in use. In the full version, cooled PV (photovoltaics) can be connected. This will mainly be for concentrating PV systems, whereby the heat should still be usable for industrial purposes or thermal power generation. All hydraulic and electrical line feedthroughs are required in this case. On the other hand, purely thermal collectors, preferably concentrator systems for high temperatures or for direct steam generation, can be used. The installation of the electrical system is not necessary here. Mixed operation is also conceivable, so that, for example, the outer collectors are uncooled PV panels, while the inner collectors are purely thermal energy generators. These systems are particularly easy to implement and are of interest to individual households - less so for industrial use. Depending on what is needed, certain components can be omitted. With the full version, it is possible to switch from purely thermal heaters to hybrid systems with PV at an advanced stage of development.

Another type of modularity relates to the technical design. The idea is to use as many identical parts as possible, which compresses the parts list and consequently reduces development and manufacturing costs.

All the above criteria can be met, as can be seen from the following description and figures.

One object of the invention is achieved by a pivot module comprising at least one connection flange body and a pivot flange body, wherein the connection flange body comprises at least one fastening section with at least one first flange receptacle for receiving a boom of a solar system and a second flange receptacle for receiving a holding arm of a first energy module, such as a (mirror-concentrating) solar collector or a PV module, wherein the pivot flange body comprises at least one fastening section with at least one third flange receptacle for receiving a holding arm of a second energy module, such as a (mirror-concentrating) solar collector or a PV module, wherein the pivot flange body is rotatably mounted on the connection flange body in order to transfer the second energy module from an operating position into a closed position, in which closed position the first energy module is closed by the second energy module.

The rotatable mounting of the swivel flange body on the connecting flange body creates a particularly simple way of bringing the second energy module into the closed position. In addition, the rotatable mounting of the swivel flange body on the connecting flange body creates the prerequisite for establishing a simple and reliable connection of electrical and/or hydraulic lines of the boom, the first energy module and/or the second energy module to electrical and/or hydraulic lines of the boom, the first energy module and/or the second energy module.

Preferably, the fastening section of the connection flange body has a fourth flange receptacle for receiving a holding arm of a third energy module, such as a (mirror-concentrating) solar collector or a PV module, and the Fastening section of the swivel flange body comprises a fifth flange receptacle for receiving a holding arm of a fourth energy module, such as a (mirror-concentrating) solar collector or a PV module, so that the fourth energy module can be transferred together with the second energy module from an operating position into a closed position, in which closed position the third energy module is closed by the fourth energy module.

This makes it possible to create a star-shaped arrangement of the energy modules in the operating position and a particularly space-saving, compact and protected closed position. In particular, this preferred embodiment of the swivel module according to the invention allows four energy modules to be attached to the boom of the solar system, which four energy modules can be reduced to two compact units, each consisting of an inner energy module and an outer energy module, by the rotary movement of the swivel flange body, which outer energy module closes the inner energy module in the closed position.

It is preferably provided that the fastening section of the connection flange body and/or the fastening section of the swivel flange body is/are designed in the shape of a spherical segment.

This gives the swivel module a particularly high level of stability. In addition, the volume enclosed by the two ball segments forms an area for accommodating additional components, in particular connections, couplings, etc.

It is preferably provided that the fastening section of the connection flange body, preferably the connection flange body, and/or the fastening section of the swivel flange body, preferably the swivel flange body, is/are designed as a die-cast part or injection-molded part.

This makes it possible to simplify the manufacture of the swivel module and to keep the manufacturing costs of the swivel module according to the invention low. In addition, the structural integrity of the swivel module is increased.

It is preferably provided that the fastening section of the connecting flange body, preferably the connecting flange body, and the fastening section of the swivel flange body, preferably the swivel flange body, are manufactured as identical parts or are identical parts in the raw production. This has the advantage that only one tool is required, which in turn reduces the manufacturing costs.

It is preferably provided that the fastening section of the swivel flange body contacts the fastening section of the connection flange body in the operating position of the second energy module, preferably at end stops.

In this preferred embodiment, the fastening sections of the connection flange body and the swivel flange body contact each other when the swivel flange body (or the second and possibly also the fourth energy module) is in the operating position. This allows the swivel flange body and the attached energy modules are stored particularly stably on the boom of the solar system in the operating state. In particular, when the fastening sections are designed in the shape of a spherical segment, the contact of the fastening sections - or more generally: the swivel flange body and the connection flange body - enables a particularly favorable force dissipation via the connection flange body to the boom of the solar system. This increases the operational reliability of the solar system in which the swivel module according to the invention is used. In addition to the operating position (open state), there can also be at least one other position in which the two flange bodies (i.e. the connection flange body and the swivel flange body) or their fastening sections contact each other. There can also be another end stop on the swivel module, which fixes the closed state (closed position), although this can also take place via the energy modules, for example via mirror ends of the collectors or edges of the PV modules.

There should also be an end stop when the collectors are removed. As explained below, it can also be provided that the motors that cause the swivel movement recognize via the load bearing that the gear is at the stop.

It is preferably provided that the first energy module and/or the second energy module and/or the third energy module and/or the fourth energy module is/are designed as a solar collector, in particular a thermal one.

The swivel module proves to be particularly advantageous here, as the swivel connection ensures particularly reliable protection of the sensitive components of the solar collectors in the closed position. In particular, the solar collectors can be protected from physical damage in this way.

It is preferably provided that the first energy module and/or the second energy module and/or the third energy module and/or the fourth energy module is designed as a photovoltaic module.

In connection with photovoltaic modules (PV modules), the swivel module also offers particularly reliable protection for sensitive components of the PV modules, which components remain exposed in conventional solar systems - even when the solar system is not in operation.

It is preferably provided that the first energy module and the third energy module are each formed by a solar collector, in particular a thermal one, and the second energy module and the fourth energy module are each formed by a photovoltaic module.

This combination of solar collectors (connected to the connection flange body) and photovoltaic modules (connected to the swivel flange body) enables a particularly compact and space-saving design of the solar system in the closed position, especially since the photovoltaic modules, which usually take up less space, can serve as a cover for the generally larger solar collectors. It is preferably provided that the first energy module and the third energy module are each formed by a solar collector, in particular a thermal one, and the second energy module is formed by a cover for closing the first energy module and the fourth energy module is formed by a cover for closing the third solar collector.

In this case, a loss in the functionality of the solar system equipped with the swivel module is consciously accepted in order to enable the two energy modules attached to the connection flange body to be secured as simply and reliably as possible. It is also possible to adapt the cover(s) specifically to the energy module to be connected.

Preferably, the connecting flange body and the swivel flange body are fluidically connected to one another via at least one rotary feedthrough.

The at least one rotary feedthrough enables the fluidic connection of the connection flange body and the swivel flange body or their flange receptacles, and at the same time allows the swivel flange body to be transferred to the closed position (or the rotary movement of the swivel flange body, which rotary movement transfers the second and possibly the fourth energy module from the operating position to the closed position). This creates a particularly simple and reliable connection of the lines of the boom and the holding arms of the energy modules.

It is preferably provided that connection modules for hydraulic and/or electrical lines of the holding arms and/or the boom are provided at through-openings of the flange receptacles, wherein the connection modules are preferably designed such that the hydraulic and/or electrical lines can be inserted into the connection modules during assembly.

This makes it particularly easy to mount the support arms and/or the boom on the connection flange body and/or the swivel flange body. Because the connection modules are provided directly on the flange mounts, the respective hydraulic and/or electrical connections can already be made on the fastening sections of the connection and swivel flange body - which are easily accessible from the outside - which means that laborious work inside the connection and/or swivel flange body is no longer necessary. This makes handling the swivel module - especially during installation in a corresponding solar system - much easier.

It is preferably provided that the connection flange body and/or the swivel flange body comprises/comprising pipes for electrical cables in order to guide these cables to at least one terminal box of the swivel module.

In other words: The connection flange body and/or the swivel flange body can have pipes which lead to at least one terminal box. In this way, electrical cables, in particular those of the holding arms and/or the boom, can be led to or into the terminal box in a particularly simple and reliable manner, without any problems when mounting the swivel module on the boom or the Mounting the support arms on the swivel module would require complex cabling.

It is preferably provided that the connection flange body and/or the swivel flange body has/have receptacles for adapters and/or retaining plates.

This makes it possible to accommodate a mechanical unit that mediates a relative movement between the connecting flange body and the swivel flange body, such as a gear unit, in or on the swivel module in a particularly simple and compact manner with precise dimensions. In this way, a simple and reliable transfer of the swivel flange body from the operating position (the position in which the second energy module is in the operating position) to the closed position (the position in which the second energy module is in the closed position) is possible.

It is preferably provided that the swivel module comprises at least one gear, which gear is preferably arranged between a first holding plate connected to the connection flange body and a second holding plate connected to the swivel flange body, in particular connected to these holding plates.

The force can therefore be transmitted directly via the retaining plates, which in turn are connected to the swivel flange body or - via the adapters - to the connecting flange body. In particular, the first retaining plate can be connected to the connecting flange body via a (first) adapter. The gearbox can then be mounted on this first retaining plate. An output of the gearbox can then be connected to the second retaining plate, which second retaining plate is itself mounted on the swivel flange body. By using adapters and retaining plates, different gearboxes (e.g. gearboxes of different sizes) can be used with the swivel module, which means that the swivel module can be easily adapted to different requirements.

It is preferably provided that the swivel module comprises at least one bearing, which bearing is preferably arranged between a third retaining plate connected to the connection flange body and a fourth retaining plate connected to the swivel flange body, in particular connected to these retaining plates.

By using such a bearing (also called a bearing module or bearing unit), the rotatable mounting of the swivel flange body on the connecting flange body on the side opposite the gearbox is ensured. The bearing can also - analogous to the gearbox - be arranged between two retaining plates, in particular the third retaining plate, which is attached to the connecting flange body via a (second) adapter, and the fourth retaining plate, which is mounted on the swivel flange body, and connected to these retaining plates. This can provide a rotating mounting of the two retaining plates on each other, and thus also of the swivel flange body on the connecting flange body. By using adapters and retaining plates, different bearings can be used in the swivel module, which means that the swivel module can be easily adapted to different requirements.

Preferably, it is provided that a first hydraulic unit is arranged within the connection flange body, which first hydraulic unit preferably has a respective Carrier plate is connected to the flange receptacles of the connection flange body, wherein the carrier plates of the first hydraulic unit are particularly preferably connected to one another via rigid lines.

The first hydraulic unit is initially used to connect hydraulic lines of the boom, the support arm of the first energy module and, if applicable, the support arm of the third energy module. Accordingly, the first hydraulic unit can comprise a first carrier plate, which first carrier plate is connected to the first flange receptacle, a second carrier plate, which second carrier plate is connected to the second flange receptacle, and, if applicable, a third carrier plate, which third carrier plate is connected to the fourth flange receptacle. Connections for the corresponding hydraulic lines can be fixed in or on the respective carrier plates, so that the hydraulic connections between the swivel module, boom and support arm(s) are particularly easy to establish. The connections in or on the carrier plates of the first hydraulic unit can be connected to one another via rigid lines, since although the swivel flange body is movable (in particular rotatable) relative to the connection flange body, the individual components of the first hydraulic unit do not have to carry out any (rotational) movements relative to one another. This means that the hydraulic lines can be routed particularly stably and well protected in the connection flange body, which significantly reduces the susceptibility of the swivel module to errors. The rigid routing of the hydraulic lines in the connection flange body also offers the possibility of particularly reliable and effective insulation, which increases the efficiency of the solar system in which the swivel module is used.

It is preferably provided that a second hydraulic unit is arranged within the swivel flange body, which second hydraulic unit is preferably connected to the flange receptacles of the swivel flange body via a respective carrier plate, wherein the carrier plates of the second hydraulic unit are particularly preferably connected to one another via rigid lines.

The second hydraulic unit is initially used to connect hydraulic lines of the holding arm of the second energy module and, if applicable, the holding arm of the fourth energy module. Accordingly, the second hydraulic unit can comprise a fourth carrier plate, which fourth carrier plate is connected to the third flange receptacle, and, if applicable, a fifth carrier plate, which fifth carrier plate is connected to the fifth flange receptacle. Connections for the corresponding hydraulic lines can be fixed in or on the respective carrier plates, so that the hydraulic connections between the swivel module and the holding arm(s) can be made particularly easily. The connections in or on the carrier plates of the second hydraulic unit can be connected to one another via rigid lines, since although the swivel flange body is movable (in particular rotatable) relative to the connection flange body, the individual components of the second hydraulic unit do not have to carry out any (rotational) movements relative to one another. This means that the hydraulic lines in the swivel flange body can be guided in a particularly stable and well-protected manner, which can significantly reduce the susceptibility of the swivel module to errors. The rigid routing of the hydraulic lines in the swivel flange body also offers the possibility of particularly reliable and effective insulation, which can increase the efficiency of the solar system in which the swivel module is used. It is preferably provided that the first hydraulic unit and/or the second hydraulic unit is/are each formed by a welded construction.

This enables a particularly simple, stable and cost-effective production of the first hydraulic unit and/or the second hydraulic unit.

It is preferably provided that the connection flange body and/or the swivel flange body each comprise/comprise a cover, which cover closes an interior space formed between the respective fastening section and the cover, preferably except for openings for hydraulic lines and/or further openings for electrical lines, on the inside.

The term "inside" refers to that side of the connection flange body or the swivel flange body which, in the operating position, faces the swivel flange body or the connection flange body and is thus, in a sense, inside the swivel module. The cover enables the formation of a protected and sealed interior space between the fastening section and the cover. In the case of a spherical segment-shaped fastening section, the cover can, for example, serve to cover the open area of the spherical segment. The openings can include pipe outlets for the passage of cable harnesses from the holding arms and pipe outlets for the passage of a main cable harness from the boom. The cable harnesses can be led to the distribution box via these pipe outlets, which distribution box can provide clamp and/or plug connections and can also be used to connect a motor to operate the transmission. The cover can have an opening, which opening can be used to pass hydraulic lines, in particular a connection between the first hydraulic unit and the second hydraulic unit. The claddings therefore make it possible to define passage points for hydraulic and/or electrical lines and cables from the inside of the connection and/or swivel flange body. This makes it easier to connect these lines and cables to other components of the swivel module or solar system, as well as to install the swivel module.

Preferably, the interior is closed on the outside by means of positioning covers, which cover the through-openings of the flange receptacles and preferably serve to fix the pipes.

The term "external" refers to the side of the connection flange body or the swivel flange body that faces away from the swivel flange body or the connection flange body in the operating position. Analogous to the covers, the positioning covers can be used to define passage points for hydraulic and/or electrical lines and cables from the inside of the connection and/or swivel flange body. This makes it easier to connect these lines and cables to other components of the swivel module or solar system, as well as to install the swivel module. If the connection flange body and/or the swivel flange body includes pipes for electrical cables, these pipes can be attached to the positioning covers and thus connected to external cables and lines (of the boom and/or the support arms) via the positioning covers. It is preferably provided that the carrier plates have connection modules in order to be able to fluidly connect the first hydraulic unit and/or the second hydraulic unit to the support arms (holding arms) and/or the boom.

If the connection modules are provided directly on the support plates, this makes it easier to connect the hydraulic lines of the boom and/or the support arms due to the locally specified or fixed connection options. This creates the prerequisite for a particularly simple and time-saving installation of the swivel module on the boom or the support arms.

It is preferably provided that the connection modules are of modular construction and, in particular, that all connection modules comprise a connection body, wherein the connection bodies of the individual connection modules differ from one another at most by bores for pipe branches.

There can be different sealing sets, resulting in different variants of connection modules. However, the connection body or a welded part can always be designed the same. This reduces costs in production and in production logistics in mass production.

It is preferably provided that the connection modules comprise sliding sleeves and preferably O-rings.

Connection modules designed in this way enable a sufficiently sealed connection of all fluid-carrying lines of the holding arms and/or the boom to the swivel module. In particular, the connection modules according to this preferred embodiment can absorb temperature-related material expansion particularly well, which can prevent leaks. Overall, the structure of the swivel module can be kept simple and production costs low by using the connection modules according to this preferred embodiment.

Preferably, holes are provided or introduced into the ball heads of the connecting bodies. These holes can point towards the center of the ball heads, aligned with the axial direction of the rigid lines of the respective hydraulic unit or the hydraulic pipes (to be welded on). In other words: the holes can be directed from the center of the ball heads in the direction of a longitudinal axis of a section of the respective rigid line adjoining the ball head.

Each individual ball head can be drilled differently, in particular the individual holes can differ from one another in terms of their respective orientation. These holes can be made particularly cost-effectively in the ball heads using CNC machining. By making a suitable hole in the ball head of the respective connection body and then welding on the corresponding rigid line, a particularly advantageous line routing in the respective hydraulic unit can be achieved. In particular, this makes it possible to design the rigid lines of the hydraulic unit largely without bends. For example, the two hydraulic units of the connection flange body and the swivel flange body have a total of 12 rigid lines if the swivel module is to be connected to the boom and four support arms as intended; of these 12 pipes to be welded in, only two pipes have to be designed with bends or bent sections due to the design described above. This reduces manufacturing costs.

Preferably, it is provided that connecting bodies are provided at the openings of the cladding, to which connecting bodies the piping for the rotary union is connected.

This creates a particularly simple connection between the first hydraulic unit of the connection flange body and the second hydraulic unit of the swivel flange body.

Preferably, the rotary union is positioned axially centered between the connection flange body and the swivel flange body.

As a result, a swivel movement carried out by the swivel flange body in order to transfer the second energy module from the operating position to the closed position can be followed by the rotary union without forces acting on the rotary union which would lead to a deflection of the rotary union from its axis-centered position.

It is preferably provided that the rotary feedthrough is formed via two connecting bodies, which are preferably fixed to one another via a two-part holding fork.

In this way, the rotary union can be implemented particularly easily and at the same time a reliable connection can be established between the rigid lines of the two hydraulic units.

Preferably, at least one terminal box mounted on the cladding is provided.

By accommodating the terminal box on the panel, in particular on a side of the panel facing away from the respective interior, a particularly simple connection of the electrical lines of the boom, the first and second support arms, and possibly also the third and fourth support arms is possible. In particular, the two terminal boxes, namely a first terminal box mounted on the panel of the connection flange body and a second terminal box mounted on the panel of the swivel flange body, can be connected to one another by a flexible cable or a cable with a flexible section, which cable is positioned outside the two flange bodies. This represents a particularly compact and space-saving, but at the same time also extremely maintenance-friendly connection option.

Preferably, the terminal box provides a pipe for the passage of electrical cables and/or a plug connection. This makes it easier to connect electrical cables from the boom and/or the support arms to the swivel module. To connect these electrical cables, a (flexible) electrical connection of the terminal boxes of the swivel module is sufficient.

Preferably, the terminal box provides a plug connection for the motor electrics.

This makes it particularly easy to supply and control the motor, which transmits the swivel movement via the gearbox.

It is preferably provided that the connection flange body and the swivel flange body are arranged mirror-symmetrically to one another in a swivel position, in which swivel position the second energy module and/or the fourth energy module is/are arranged in the operating position, with respect to a vertical plane, in which vertical plane an axis of rotation of the rotatable bearing of the swivel flange body on the connection flange body is located.

This makes it possible to achieve a particularly compact and space-saving design of the swivel module, particularly in the case of flange bodies with a spherical segment shape.

An object of the invention is also achieved by a system comprising the swivel module in one of the embodiments described above and the first energy module, which first energy module is fastened via its holding arm to the second flange receptacle of the connection flange body, the second energy module, which second energy module is fastened via its holding arm to the third flange receptacle of the swivel flange body, the third energy module, which third energy module is fastened via its holding arm to the fourth flange receptacle of the connection flange body, and the fourth energy module, which fourth energy module is fastened via its holding arm to the fifth flange receptacle of the swivel flange body, wherein the energy modules are positioned in the operating position at corner points of a square or rectangle, in the center of which the swivel module is positioned.

All of the above-mentioned advantages can be achieved with this system; the above statements therefore also apply to the system according to the invention. The arrangement of the energy modules allows solar systems which include the system according to the invention to be operated in a particularly energy-efficient manner.

An object of the invention is also achieved by a solar system comprising the system described above, wherein the connection flange body is fastened to a first boom of the solar system.

All of the above-mentioned advantages can be achieved by this solar system; the above statements therefore also apply to the solar system according to the invention.

Preferably, the solar system comprises a further embodiment of the system described above, wherein the connection flange body of the further system is fastened to a second boom of the solar system. This makes it possible to provide a solar system with a total of 8 energy modules, which can be folded onto each other in pairs in the closed position to form 4 closed units.

Preferably, it is provided that a leakage chamber is formed between the positioning cover of the connection flange body or the swivel flange body and an insert pot of the boom or the support arm (holding arm), from which leakage chamber a line is led to the outside.

The positioning cover and the insert pot can form a gap called a leakage chamber, in which liquid collects in the event of a leak in the boom and/or the support arms. A line with a cap now leads out of this interior. If the energy modules are in the operating position, the liquid can drain (downwards). During a routine inspection or when looking for a leak, you can determine whether there are any leaks by opening the cap. This improves the user-friendliness and maintenance friendliness of the solar system.

Pipe outlets leading to a terminal box are provided on the respective flange mounts for the electrical cables from the support arms (holding arms) and the boom. The connection modules are part of a hydraulic distribution system in the swivel module. When the holding arms and the boom are assembled, the piping from these components is automatically pushed into the connection modules and sealed with the hydraulic distribution system of the swivel module. The entire assembly is completed by threading the electrical cables through, tightening the flange screw connection, connecting the electrical system and closing the terminal box. Incorrect assembly is not possible because care is taken to ensure that only the correct plug or clamp connections fit. The assembly can be carried out by two people. Specialist personnel are not required for the assembly work. If a connection module becomes leaky, the flange connection can be exposed by removing the holding arm. A new sealing kit can now be installed from the outside. There is nothing to do with the hydraulic distribution system. This is a welded construction and no leaks are to be expected. This system does not require maintenance. It is foamed in behind a panel and cannot be opened.

Further details on the technical design are described in more detail in the figure description.

Ways to carry out the invention

Fig. 1 illustrates the task for mounting the collectors (mirror collectors, energy modules). The collectors are attached to holding arms 1, which have flanges for fastening. Since four collectors are arranged spherically symmetrically, 90° to each other in a star shape when viewed from above, corresponding counter flanges are also provided for mounting in this division on a preferably spherical body, the flange unit (swivel module). Another A counter flange on this flange unit is to be provided for the boom 2, which has a flange identical to the support arms.

Fig. 2 shows the connection periphery for hydraulics and electrics. Electrical cable harnesses 3, 4 and hydraulic lines 5.1, 5.2 emerge from the support arms 1 and the boom 2. The main cable harness 3 is routed in the boom 2, while line 4 for the power electrics (PV current) and, if necessary, sensor cables are routed in the support arms 1. During assembly, the electrical cable harnesses 3, 4 must be routed to a distribution box with clamp and/or plug connections by providing appropriate pipe openings. The hydraulic lines 5, supply and return 5.1, and cleaning line 5.2 should be connected by sealing slide-in connections to a hydraulic distribution unit (hydraulic unit), which connects the hydraulics 5 from the boom to the individual collectors. The connection should be made automatically when the flanges of the support arms 1 and the boom 2 are assembled.

Fig. 3 shows the specification of how the collectors should be opened and closed. The hydraulic pipes and the cable harnesses from the pivoting support arms must be routed over the rotation axis.

Fig. 4 shows the connection flange body 6 for receiving the support arms 1 of the collectors and the boom 2 in two views. This is preferably a solid die-cast part with mechanical processing. The flange mounts for the support arms and the boom have threaded holes. Assembly should only take place from the outside, since the interior will be covered and no access is provided to provide screw nuts. To reinforce the threads, it is conceivable to cast steel inserts with threaded holes. The spherical shape provides high rigidity against bending and torsion. The flange bodies 6, 7 have flat surfaces 38 with threaded holes for receiving adapters 8, 9 and retaining plates 12 (see Fig. 7).

Fig. 5 shows the swivel flange body 7 for holding the holding arms 1 of the swiveling collectors. Both flange bodies (connection flange body 6, swivel flange body 7) can be manufactured with the same tool. The parts are easy to demold and can be manufactured with a two-part tool. For example, aluminum die casting or injection molding with metal inserts can be considered. The difference to the connection flange body 6 lies solely in the covering of the connection flange.

Fig. 6 shows the geometric position of both flange bodies 6, 7 in the open and closed state. Open means that when the collectors are connected, they are open and in an operating position. When the swivel flange body 7 is swiveled through 180°, the collectors come into the closed state (closed position). Since the mirrors of the collectors must close exactly, mechanical machining of the flat surfaces of the flange mounts is advantageous. It will also be useful to provide dowel pins (not shown here). This also applies to the flanges of the support arms 1 (holding arms 1) and the boom 2. As can be seen, the flange bodies 6, 7 are at the stop in both positions. This guarantees exact positioning at the end positions, especially in the operating position and in the closed position. When the stop is reached, the gear is pre-tensioned so that there is a play-free force connection and damage due to shaking (gusts of wind) is prevented. The motors cannot rotate more and therefore consume more power. The change in load from tension to compression is detected by the control system and the signal is given to switch off the servo motors. Limit switches and the necessary cabling can be dispensed with.

Fig. 7 shows the rotating connection of both flange bodies 6, 7. The swivel flange body 7 is stably mounted via the gear 10 and a bearing module 11 (bearing unit, bearing). Two adapters 8, 9 enable the precise installation of the gear unit 10 and bearing unit 11. Retaining plates 12 are mounted together with the adapters 8, 9, which hold the gear 10 and the bearing unit 11. The adapters 8, 9 can be die-cast parts or injection-molded parts. It is conceivable to use extruded aluminum profiles, which are available by the meter. This enables a modular design for the installation of different gear and bearing types, purely by adjusting the adapter depth via cutting. The bearing unit 11 is typical of a wheel bearing from the automotive sector and is therefore available ready-made with sealing at a reasonable price as a mass product. The gear 10 is heavily geared down and self-clamping. Ideally, a worm drive is provided on the motor side and a planetary drive on the power side. Gearboxes of this type are very compact and can transmit high forces. Since these gears are often used in industrial robots, a suitable gear box should also be found here without special production.

Fig. 8 shows an internal cover 13 with installation of through-pipes 28 for the electrical system in two views. For better illustration, the connection flange body 6 is shown transparently. With the cover 13 and positioning covers 17, which are arranged on flange receptacles of the connection flange body 6 (shown transparently), a protected and sealed interior is formed. The pipe outlets 14 are used to lead through the cable harnesses from the holding arms 1. The pipe outlet 15 is used to lead through the main cable harness from the boom 2. The cable harnesses go into a distribution box, which provides clamp and/or plug connections. The motor is also connected to this. The cable from the motor 16 is preferably provided with a plug, as shown here. The pipes 28 for the electrical system (electrical cables) can be seen, which are held by the positioning covers 17 and the cover 13. The cover 13 has a large opening 40, which is used for the hydraulic system to pass through. If no hydraulic passage is provided, this opening is closed by a cover cap 37 (seen in Fig. 24).

Fig. 9 shows the hydraulics (hydraulic unit) which is installed in the interior of the two flange bodies 6, 7. These are two welded constructions. Connection modules 19 with hemispherical ends are welded onto carrier plates 18 (preferably spot welding) or screwed in via a thread. The ball heads have ball-centric holes in the axial direction of the individual connection pipes. Each individual ball head is drilled differently. If the carrier plates 18 are positioned precisely, for example by mounting them on the flange bodies 6, 7 or on a special device, CNC machining is a cost-effective method of manufacturing the holes. As can be seen, only two of the twelve pipes to be welded in need of bends. The welding of all parts can be carried out fully automatically in series. The connection modules 19.1 and 19.2 differ in the connection dimensions of the pipes to be inserted. The connection modules 19.3 and 19.4 are pipe connections which do not allow axial displacement or allow for twisting. As with 19.1 and 19.2, the connection module 19.3 is provided with a guide bush for inserting a pipe socket. Further details can be found in Fig. 19.

Fig. 10 shows a detailed view of the connecting pipes to the axis-centered rotary unions or the connection modules 19.1. The connection modules 19.1 take over the rotary movement and can also be referred to as "rotary unions" in this case. In order to prevent them from being squeezed out due to the system pressure (up to 30 bar during operation), the two rotary unions or connection modules 19.1 are fixed to one another using a two-part retaining fork 20.

Fig. 11 shows the entire hydraulic system inside the swivel module, consisting of the two welded parts (first hydraulic unit in the interior of the connection flange body 6, second hydraulic unit in the interior of the swivel flange body 7) with the support plates 18 and the connection pipes to the rotary feedthrough (19.1, 20). The hydraulic "internal construction" of the flange bodies 6, 7 is carried out by mounting both welding modules on the support plates 18. The welding modules can be easily accessed and precisely inserted and secured with nine and six screw connections each. Insulating blocks are provided on the screw connections to prevent thermal bridges. This is a one-time assembly, as there will no longer be access to the finished part, as the interior of the flange body 6, 7 (the space that is enclosed by the fastening section of the respective flange body 6, 7, on the inside additionally by the cover 13 and on the outside additionally by the positioning cover 17) is foamed. The pipes into which the rotary unions 19.1 are inserted support each other in the bent area against the pushing-out pressure. It is conceivable to set a spot weld connection here or to provide another type of fastening.

Fig. 12 shows a protective insulation, sealing the facings, in two views. There is a T-shaped insulation shell 22 and a fork-shaped insulation shell 21. Both insulation shells are split in two to facilitate assembly. Two-part sealing rings 24 are attached to the pivot points of the insulation shells 21, 22, which can be removed or installed using spring locks 23. This makes it possible to check in a few simple steps whether there are any leaks. The two-part insulation shells 21, 22 are held together by sealing rings 24 and seals 25 on the facings. Cable ties could also be attached. These can be quickly replaced.

Fig. 13 shows the overall installation for electrics and hydraulics on the connection flange body 6. A front and rear view are shown, as well as a view into the interior (cover is transparent). As can be seen, a compact part is provided that is no longer opened. The heat pipes (hydraulic unit) can be insulated and/or the entire interior can be filled with foam. If the pipes are carefully welded, no leaks are to be expected.

Fig. 14 shows the overall installation for electrics and hydraulics on the swivel flange body 7. Here, too, the same applies as already described in Fig. 13. Lines for cleaning and the passage for the main cable harness to the boom 2 are omitted or are not present here, since only the two holding arms 1 of the energy modules have to be connected. Fig. 15 shows the electrical terminal box 26 with connection 16.1 for a motor cable 16. If the collectors are designed purely for thermal purposes, no electrical cables lead to them. The openings provided in the terminal box are closed with plugs 27. The terminal box 26 is mounted in a sealed manner on the cover 13.

Fig. 16 shows the overall installation with two terminal boxes 26 including all electrical piping in two views. The pipes 28, which are supported by the positioning covers 17 and the cover 13, are clearly visible. Pipes 28.1 are connected to the terminal boxes 26, which lead the electrical system (via flexible electrical cables 30) close to the axis of rotation. The electrical cables 30 are enclosed in grommets 29 at the outlets of these pipes 28.1, so that a seal is provided. The cables 30 are suitable for outdoor use and are flexible. This means that they can follow the movement around the pivot axis.

Fig. 17 shows the complete swivel module in the delivery state in two views. All sealing sets (guide sleeve and O-ring) on the flange mounts can be changed from the outside (see Fig. 19 for details). To connect the electrical system, only the terminal boxes 26 need to be opened. Ideally, different plug connections are provided so that no incorrect connection is possible. The complete installation of the collector system and also the assembly with the swivel module presented here should not require any specialist personnel. The collector unit with holding arm is always constructed in the same way (no mirror-symmetrical parts, but identical parts). The hydraulics are connected in such a way that the flow always flows correctly through the supply and return lines. This is particularly important for steam-generating heaters. The line cross-sections are dimensioned so that the lines can be flowed through by both liquid and saturated steam. It would be possible to subsequently replace a liquid-flow solar heater with a steam generator.

Fig. 18 shows details of the flange ends of the support arms 1 and the boom 2. The positioning cover 17 and the insert pot 31 form an intermediate space. Water or liquid collects here in the event of a leak. A line 32 leads out of this interior space and is provided with a closure cap 33. If the collectors are open or the energy modules are in the operating position, the water or liquid can run down from the intermediate space. During a routine inspection or when looking for a leak, you can see whether everything is OK by opening the closure cap.

Fig. 19 shows individual components for modular installation. There are five support plates 18 in the entire installation. These are attached to the flange bodies on the inside of the flange mounts via insulating disks 34. A corresponding recess 35 is provided to prevent heat conduction from the hot pipes to the suspensions and to the cleaning line. The recess 36 also prevents heat conduction and serves as an opening for the electrical piping. The connection modules 19 are available in 4 versions (which are also referred to below with reference symbols 19.1, 19.2, 19.3 and 19.4). These differ only in the sealing sets. The first variant of the connection modules 19.1 is available eight times for the flow and return from the collector arms, three times for the cleaning line and twice for the rotary feedthrough. The second variant of the connection modules 19.2 is available twice for the flow and return from the boom. The third variant of the connection modules 19.3 and the fourth variant of the connection modules There are two of each type 19.4. In the third and fourth variants of the connection modules 19.3 and 19.4, the union nuts 41 are used to tighten a seal, which in this case is a sliding sleeve 42. In the first and second variants of the connection modules 19.1 and 19.2, the union nuts are provided to prevent the sliding sleeve 42 from being pushed out by the system pressure. This enables the pipes 44 to move axially. The actual sealing is carried out via the O-ring 43. With the right choice of material and precise manufacturing, leaks in the connection modules 19.1, 19.2, 19.3 and 19.4 can be ruled out. Designing for an operating pressure of 30 bar and a steam temperature of 235°C should not be a technical challenge. If a leak occurs at the flange mounts, the seal set 42, 43 can be replaced by opening the union nut.

Fig. 20 shows a PV module that is attached to the support arm 1. This is modular because it is the same support arm 1 as the one that is intended to hold the mirrors (mirror collectors). In other words: various energy modules, such as a mirror collector or a PV module, can be attached and connected to the support arm 1. The PV panel or PV module can be quickly mounted and removed using a quick-release fastener (e.g. a bayonet fastener).

Fig. 21 shows a concentrator system with mirrors (mirror-concentrating collectors) for generating electricity in a slightly open state - the second and fourth energy modules are between the operating and closed positions. The heat from the cooling can still be used for heating purposes. This technology shows great future potential for the development of corresponding solar cells. These should have a high efficiency (>25%) and only drop in performance slightly at a temperature of 150°C. In this case, the heat could still be used for air conditioning and cooking purposes. It would be conceivable to use a steam engine for a second stage of electricity generation. The electricity could also be generated at a later time using a two-phase storage system. This would be a cost-effective method for indirect electricity storage. To ensure even cooling of the solar cells, direct evaporators (e.g. heat pipes) should be used. With direct steam generation, the process for further electricity generation also becomes more efficient. The swivel module requires full equipment (hydraulics, cleaning, electrics), as shown in Fig. 17.

Fig. 22 shows another view of Fig. 21 with a better view of the swivel module. The seamless thermal insulation and encapsulation of the hydraulic system can be clearly seen. Harmful environmental influences are completely blocked. In particular, the hydraulic units are hidden behind the panels or the hydraulic units are completely housed in the interior of the connection flange body 6 and the swivel flange body 7. The two hydraulic units are connected to one another via the rotary union surrounded by the insulating shells 21, 22 (see Fig. 11 and 12).

Fig. 23 shows a hybrid system. The outer collectors or the second and fourth energy modules generate electricity using commercially available PV panels with convective air cooling. The hydraulics are therefore not required for the outer collectors (the second hydraulic unit and rotary union can be omitted). The inner collectors or the first and third Energy modules generate high-temperature heat via heating coils through which water flows 38. The pivoting mechanism allows the PV modules (second and fourth energy modules) to be moved over the mirrors (first and third energy modules), so that an enclosed space is formed when the second and fourth energy modules have reached the closed position. This also offers the possibility of providing automatic cleaning. The system is easy to implement. The heat can be used for cooling, heating and cooking purposes. This could be an interesting variant for domestic use in single-family homes. In certain regions, this can achieve an almost self-sufficient supply. The heat can also be used for seawater desalination and water treatment processes.

Fig. 24 shows another view of Fig. 23 with a better view of the swivel module. The hydraulic outlet for the outer collectors is closed by a cover cap 37. If the PV module is removed, for example due to a forecast of extremely high wind forces, the electrical system must be disconnected in the terminal box 26. The cables can then be pulled out via the through-pipes in the support arms 1 and in the swivel module.

In summary, the swivel module is characterized by the fact that a rotatable connection of the two flange bodies 6, 7 is provided. The swivel flange body 7 is stably mounted on the connecting flange body 6 via the gear 10 and the bearing module 11. The two adapters 8, 9 enable the gear and bearing unit 10, 11 to be installed with precision. The retaining plates 12, which hold the gear 10 and the bearing unit 11, are mounted together with the adapters 8, 9. The adapters 8, 9 can be die-cast parts or injection-molded parts. It is conceivable to use extruded aluminum profiles, which are available by the meter. This enables a modular design for the installation of different gear and bearing types, purely by adjusting the adapter depth via cutting. The bearing unit 11 is typical of a wheel bearing from the automotive sector and is therefore available ready-made with sealing at low cost as a mass product. The gear 10 is heavily geared down and self-clamping. Ideally, a worm drive is provided on the motor side and a planetary drive on the power side.
