Abstract

Drainage channel outflow system uses obstructions (8.1,8.2) moving in the flow direction to control, stop off or regulate the flow, one obstruction at least to rest at right angles to the channel (1) so all lie in a common plane (E). Between one obstruction and the channel wall (2) or between two facing obstructions (8.1,8.2) there is a vertical interval (12) and there is an overflow above the top edge of one of the obstructions. There is an additional outflow gap between obstruction and the channel whose section can be controlled by raising the obstruction accordingly. The obstructions come in prefered plate form and linked by joints. The load of the water flow bends the plates (8.1,8.2) in flow direction (X) and thus enlarges the flow interval (12). At reduced pressure and smaller water flow the plates re-set to reduce or even close off the interval (12).

Description

The present invention relates to a drainage system for a channel according to the preamble of claim 1.

Such drainage systems are known in many forms and designs and in use. In particular, measures for water protection are necessary, which are often much too expensive to produce. For example, the legislator demands retention basins to protect the receiving waters, i.e., streams, rivers and lakes.

Furthermore, there is a need for action in the development of new development areas, if channels in the old city area are overloaded. In particular, an unsealing and Infiltration is rarely sufficient, so that either buffer pools still have to be built or an exchange of sewer strands to protect the old town areas are due.

In addition, conventional drainage systems can usually only cost-control and control, are expensive to maintain and therefore record extremely high operating costs. In addition, especially the environmental protection to be improved with a reduction of the pelvic and in particular channel volume. It should also be saved or reduced investment costs.

The DE 195 37 274 A1 discloses a barrier for the protection of storm surges, in which a laterally pivoting arched weir can be pivoted by means of cables into an opposite reception camp. This rigid construction is very complex and allows no regulation of different streams automated in operation.

Also the DE 26 42 747 A discloses a flood trap in which angularly deployable elements are arranged in the flow to affect a flow.

A conventionally horizontally hochverschwenkbare weir is in the US 4,455,106 described.

The present invention is therefore an object of the invention to provide a drainage system, which eliminates the above-mentioned disadvantages and with which in a simple and cost-effective manner, a large mixed water flow, for example, can be braked in heavy rainfall, with drainage tips to be avoided.

Furthermore, flooding is to be prevented and a treatment plant operation thereby optimized. In addition, such a drainage system can be used in conventional duct systems or conventional duct systems can be retrofitted while reducing installation, manufacturing and maintenance costs.

The drainage system according to claim 1 solves this problem.

In the present invention, a drainage barrier according to the invention can be used in a conventional channel. Preferably, two oppositely arranged runoff obstacles are inserted into a channel. These are articulated and movable in the flow direction, in particular pivotally fixed to channel walls, in particular on a channel inner wall. They are held by a force storage element in a vertical position to the channel wall.

Preferably, a gap is formed between a drainage obstacle and the inner wall or between two adjacent opposite drainage obstacles. This can also be omitted in a closed rest position.

Also below the drainage obstacle, a bottom outlet may be provided with possibly a recessed in a pedestal drain. Also above an upper edge of the outflow obstruction may be provided in the channel an overflow.

In the present invention, water flows into a preamble of the channel, with very large amounts of water or mass flows, the level increases in the lead or in front of the drainage obstacle very quickly. As a result, high pressure forces act on the drainage obstacle, which then yield to the pressure forces and open a gap formed if necessary. In this case, the gap can be increased in such a way to continue the desired amounts of water, so that no overflow over the threshold occurs. This system works preferably purely mechanically and is also purely mechanically adjustable.

It essentially serves to reduce and absorb peak loads. Especially in rain events, the channel volume is used specifically for the blocking by the effect of the flow obstacles. The runoff is slowed down in this way. Such drainage systems, in particular drainage obstacles can be used in strands or even cascade. They are special too suitable for installation in previously existing shafts or channels.

About the bottom outlet between the bottom and at least one drain obstruction, a calculated outflow, for example, forwarded to the next holder. As the rain increases, there is a build-up in front of the at least one drainage obstruction. The water constituents sink and are transported from the bottom flow via the drain or via the bottom outlet to the sewage treatment plant.

Thus, a coarse separation of the mixed water of impurities or dirt load can be made so that the increase in the water masses is free of them. As a result, the amount of water coming to the discharge leads by the pressure-related opening of the discharge obstruction less dirt load, which also lead to the reduction of the tips. Therefore, overloaded channels can transport the discharge-delayed amount of water.

An exchange of the channels is eliminated, whereby new tank volumes can be reduced accordingly.

This drainage system can be designed by sewer network calculation and accordingly the dimensions of the discharge obstacles can be determined exactly.

In particular through the optimization of wastewater systems by activation of retention spaces in sewers and discharge delay through the use of the drainage system according to the invention, existing and also new channels can be used, whereby downpipes are reduced and discharges are slowed down.

In addition, flooding can be avoided, whereby a connected sewage treatment plant operation can be optimized.

Like a sponge, the complete sewer system can be operated very cost-effectively and with low maintenance in a purely mechanical way. In addition, such a drainage system can be used later in each slot and in particular easy to regulate. Flooding frequencies can be minimized, thereby reducing the burden of preflours.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing; this shows in

• FIG. 1 a schematic plan view of a drainage system for a channel;
• FIG. 2 a cross section through the drainage system, in particular through the channel according to FIG. 1 along line II-II;
• FIG. 3 a schematically illustrated plan view of a drainage system for a channel according to FIG. 1 as a further Auführungsbeispiel;
• FIG. 4 a schematically illustrated cross section through the drainage system, in particular through the channel according to FIG. 3 along line III-III.

According to FIG. 1 has a drainage system according to the invention R ₁ a channel 1, which is formed from lateral channel walls 2. On the front side, the channel 1 can be closed by end walls 3. In the context of the present invention, however, there is also a frontally open channel. 1

It is a cross-section, in particular in FIG. 2 shown, the channel 1 rectangular to square formed from the channel walls 2.

A sole 4 forms a lower boundary, wherein preferably a recessed drain 5 is formed centrally in the sole 4. Preferably, the sole 4 extends slightly inclined to the drain 5 in the middle. The drain 5 may be square, rectangular or semicircular.

The water flows in a flow direction X via a channel inlet 6 through the channel 1 to a channel outlet 7. Between channel inlet 6 and channel outlet 7, the channel 1 is preferably provided with a slight slope.

Important in the present invention, however, is that in the channel 1, in particular from the FIGS. 1 and 2 shows that at least one drain obstacle 8.1, 8.2 is used. The outflow obstacle 8.1, 8.2 is pivotally mounted via a hinge 9 with a channel inner wall 10 and in particular in the flow direction X pivotally.

Preferably, the drainage obstacle 8.1, 8.2 formed plate-like symmetrical plate elements, which preferably at the other end of the joint 9, a force storage element 11, in particular designed as a compression spring element, hingedly engages and is also hingedly connected to the channel inner wall 10 of the channel wall 2 ..

In this case, energy storage element 11 and the plate element of the outflow obstruction 8.1 in a rest and starting position preferably enclose an angle β of about 45 °.

In a rest position, the discharge obstacles 8.1, 8.2, in particular their plate elements lie in a plane E and preferably perpendicular to the channel wall 2, or to the channel inner wall 10th

In this case, a gap 12 is formed between the two drainage obstacles 8.1, 8.2, which water, in particular Wastewater od. Like., Which opens in the flow direction X through the channel inlet 6 into the channel 1, can flow through.

If the liquid level rises sharply in an antechamber 13 of the channel 1, the pressure on the two outflow obstacles 8.1, 8.2, which give way to the pressure of the water masses by compressing the energy storage element 11, increases. In this way, the discharge obstacles 8.1, 8.2 are moved in the flow direction X purely mechanically, so that the gap 12 is enlarged. Due to this larger gap, a considerably larger volume flow of water can be moved through, so that in this way the outflow obstacle 8.1, 8.2 regulates itself.

For fine adjustment of a rest position, a trim device 14 may be provided, which limits the length of the energy storage element 11 and in particular the position of the discharge obstacle 8.1, 8.2. Furthermore, it should be thought to change the spring stiffness or the spring constant or even a bias of the energy storage element 11 mechanically to be able to influence the spring behavior.

The effluent through the gap 12 water then passes through the channel 1, in particular through the channel outlet 2 to the outside and can be continued there.

As further out FIG. 2 shows, below a lower edge 15 of the outflow obstruction 8.1, 8.2 an opening, in particular a slot-like bottom outlet 16 is formed, which is formed like a slot. To the bottom outlet 16 also includes the embedded in the bottom 4 drain 5. The bottom outlet 16 can be replaced by a Height adjustment of at least one outflow obstruction 8.1 to 8.3 be changed.

At an upper edge 17 of the discharge obstruction 8.1, 8.2, an overflow 18 adjoins, which forms an overflow opening 19. This serves as additional protection against large water ingress, but is not used in a correct design of the drainage system.

The water flows maximally up to the upper edge 17 of the discharge obstacles 8.1, 8.2.

The operation of the present embodiment is as follows.

If water, sewage, rainwater or the like flows through channel inlet 6 into channel 1, the water is directed through drain 5, in particular dry weather discharge, at small amounts. If the water level rises, it flows through the complete bottom outlet 16 and at least partially through the gap 12.

With strongly rising water, the water can accumulate in the preassembly 13, whereby at a certain pressurization of the discharge obstacles 8.1, 8.2 give their energy storage elements 11 in the flow direction X and swing open.

As a result, the gap 12 is opened continuously and allows a larger amount of water to flow into the subsequent channel 1. As a result, a discharge delay is formed by retention spaces or return reservoirs. This can be done a rainwater treatment.

Furthermore, this drain tips are reduced, unwanted backwater are prevented and made retention spaces usable.

However, it is also important in the present invention that a regulation and control and in particular influencing of the water quantities by the pressurized pivoting of the discharge obstacles 8.1, 8.2 purely mechanical. As a result, such drainage systems R ₁ can be produced, maintained and regulated very inexpensively.

In the context of the present invention should also be that, for example, the energy storage elements 11 by torsion spring elements, coil spring elements. Like. Can be replaced, which can be arranged in the region of the joints 9. Here, the invention should not be limited.

Included in the present invention is that, for example, only a single drain obstruction 8.1 or 8.2 is inserted into the channel 1 in the manner described above. In this case, the gap 12 may then be formed between the channel inner wall 10 of the channel wall 2 and the plate member. This can also be narrow or preset in any desired arbitrary width as the default setting. The operation is the same as described above.

In a further embodiment of the present invention according to FIG. 3 a drainage system R ₂ is shown, which is constructed accordingly in the manner described above. In essence, will not be discussed again here on the individual components. It is different, however, that a discharge obstacle 8.3 one side of one of the two channel walls 2 of several elements 20.1 to 20.3 is formed. The first element 20.1 extends into the channel 1 at an angle α of approximately 0 ° to 90 °, wherein in the flow direction X the element 20.1 is set at an angle.

Following the preferably plate-like element 20.1 is followed by a bow-like element 20.2. About connecting joints 21 are the elements 20.1, 20.2 articulated with each other in connection.

Subsequent to the element 20.2, a plate-like element 20.3, preferably slightly inclined to the channel wall 2 in the flow direction, in particular to the channel inner wall 10 and terminates there in a guide rail 22 and is movably mounted there via a roller element 23. In this case, the roller element 23 a wheel, gear od. Like. Be.

If water, waste water or the like is then fed to the channel 1, a pressure is exerted on the area-like element 20. 1 when the water level in the channel 1 rises. In this way, the gap 12 which is formed between the element 20.2 and the channel inner wall 10 by moving the discharge obstruction 8.3, in particular by end-side movement of the element 20.3 in the guide rail 22 in the flow direction X, as shown in FIG FIG. 3 shown in dashed lines, enlarged. A larger amount of water can flow.

A force storage element 11 may be connected to the end of the element 20.3 in the guide rail 22 and this, for example, if it is designed as a compression spring is, back to a vertical starting or rest position, move back.

At the other end of the power storage element 11 via a locking device 24, for example, a fixable gear wheel od. Like. In the guide rail 22 position variable. In this way, influence on the position of the element 20.3 and in particular on a bias of the energy storage element 11 can be taken.

In the context of the present invention should also be that two such flow obstacles 8.3, according to the embodiment according to FIG. 1 may also be arranged opposite one another, in order then to change a preferably centrally arranged gap 12 in the manner described above.

It should also be encompassed by the present inventive concept to provide two opposing flow obstacles 8.1, 8.2 and 8.3 in the channel 1, which are also arranged outside a common plane E, for example offset in the channel.

FIG. 4 shows a similar cross section accordingly FIG. 2 , wherein below the lower edge 15 of the discharge obstruction 8.3 of the bottom outlet 16 is formed and above the upper edge 17 of the overflow 18 are provided with overflow opening 19.
