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 drain system for a channel with a channel inlet and a channel outlet.

Such drainage systems are in the most varied of forms and Execution known and common. It is special Measures for water protection necessary, which often a lot are too expensive to manufacture. For example, calls the legislature retention basin to protect the receiving water, i.e. streams, rivers and lakes.

There is also a need for action when developing New development areas if canals in the old city area are overloaded. In particular, unsealing and Infiltration are seldom sufficient, so either Buffer pools need to be built or an exchange of Canal lines due to secure the old town areas become.

In addition, conventional drainage systems can usually only be used costly regulating and controlling are expensive in the Maintenance and therefore record extremely high operating costs. In addition, environmental protection at a Reduction of the pool and especially the channel volume be improved. There should also be investment costs saved or reduced.

The present invention is therefore based on the object to create a drainage system that complies with the above Disadvantages eliminated and with which on simple and inexpensive way a large mixed water flow, can be braked in heavy rain, for example Drain peaks should be avoided.

Flooding is also to be prevented and prevented Sewage treatment plant operation can be optimized. In addition, should such a. Drainage system in conventional sewer systems can be used or conventional duct systems can be retrofitted Reduction of installation, manufacturing and Maintenance costs.

To solve this problem, at least one in Flow direction movable discharge obstacle to Limit, control, regulate or influence one Water flow is provided.

In the present invention, a conventional one can be used Channel used a drainage obstacle according to the invention become. Preferably two are opposite arranged drainage obstacles inserted into a channel. These are articulated and movable in the direction of flow, in particular pivotable on channel walls, in particular on an inner channel wall. You are from one Force storage element in a perpendicular position to the duct wall held.

Is preferred between a drainage obstacle and the Inner wall or between two neighboring ones opposite drainage obstacles formed a gap. This can also be omitted in a closed rest position.

A bottom drain can also be installed below the drainage obstacle with, if necessary, a recessed into a base Drain can be provided. Also above an upper edge of the There may be an overflow in the sewer his.

In the present invention, water flows into one In front of the canal, with very large amounts of water or mass flows, the level in the vestibule or in front of Drainage obstacle increases very quickly. Do this high pressure forces on the drainage obstacle, which then Give pressure forces and a possibly formed gap open accordingly. The gap can be such be enlarged to the desired amount of water to continue, so that as far as possible no overflow over the Threshold occurs. This system preferably works purely mechanically and can also be regulated purely mechanically.

It essentially serves to break down and absorb Peak loads. Especially during rainy events the effect of the drainage obstacles targeted the channel volume used for stowage. The drain is this way slowed down. Such drainage systems, in particular Drainage obstructions can be stranded or even can be used in cascade. They are special too for installation in existing shafts or ducts suitable.

About the bottom outlet between the sole and at least one Runoff obstacle is a calculated runoff, forwarded to the next bracket, for example. With increasing rain creates a backlog before the at least an obstacle to drainage. The water content drops and are from the bottom flow over the drain or over transported the bottom outlet to the sewage treatment plant.

A rough separation of the mixed water from Contamination or dirt load are carried out, so that the rising water masses are free of them. This leads to the discharge of water due to the pressure-related opening of the drainage obstacle less dirt load with that also to reduce the Lead tips. Therefore, overloaded channels can Transport the delayed amount of water.

An exchange of the channels is omitted, with new pool volumes can be reduced accordingly.

This drainage system can be calculated by sewer network interpret and accordingly the Determine the dimensions of the drainage obstacles exactly.

In particular by optimizing sewage systems by activating retention spaces in sewers and drainage delay through the use of the Drainage system according to the invention can existing and new channels are also used, with drain peaks reduced and drains are slowed down.

In addition, flooding can be avoided, including one connected wastewater treatment plant operations can be optimized can.

The complete sewer system can be cleaned like a sponge mechanical way very inexpensive and low maintenance operate. Such is also a drainage system can be retrofitted in every shaft and in particular easy to regulate. The flooding frequency can are minimized and thereby the pollution of receiving water be reduced.

Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in

Figure 1 is a schematic plan view of a drain system for a channel;

FIG. 2 shows a cross section through the drainage system, in particular through the channel according to FIG. 1 along line II-II;

FIG. 3 shows a schematic plan view of a drainage system for a channel according to FIG. 1 as a further exemplary embodiment;

4 shows 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, a drainage system R ₁ according to the invention has a channel 1, which is formed from side channel walls 2. The end of the channel 1 can be closed by end walls 3. Within the scope of the present invention, however, there is also a channel 1 that is open at the end.

Is cross-sectional, as in particular in FIG. 2 shown, the channel 1 rectangular to square the channel walls 2 formed.

A sole 4 forms a lower limit, whereby preferably a deepened drain 5 in the center of the sole 4 is formed. The sole 4 preferably runs slightly in the middle inclined to the drain 5. The drain 5 can be square, be rectangular or semicircular.

The water flows in a flow direction X over one Channel inlet 6 through channel 1 to a channel outlet 7. Between channel inlet 6 and channel outlet 7 is preferred channel 1 has a slight slope.

However, it is important in the present invention that in channel 1, as in particular from FIGS. 1 and 2 emerges, at least one drain obstacle 8.1, 8.2 is inserted. The drain obstacle is 8.1, 8.2 articulated via a joint 9 with a channel inner wall 10 and in particular pivotable in the direction of flow X. stored.

The drain obstacle 8.1, 8.2 is preferably plate-like formed from symmetrical plate elements to which preferably at the other end of the joint 9 Energy storage element 11, in particular as a compression spring element trained, joint-like attacks and with the Channel inner wall 10 of the channel wall 2 is also articulated connected is.

Force storage element 11 and that close Slab obstacle 8.1 plate element in a rest and Starting position preferably an angle β of about 45 ° on.

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

It is between the two drain obstacles 8.1, 8.2 a gap 12 is formed, which water, in particular Waste water or the like, which in the direction of flow X through the Channel inlet 6 opens into channel 1, can flow through.

Rises in an anteroom 13 of channel 1 Liquid level increases sharply, so the pressure increases the two discharge obstacles 8.1, 8.2, which the pressure the water masses by squeezing the Give up force storage element 11. That way purely mechanically the discharge obstacles 8.1, 8.2 in Flow direction X moves, so that the gap 12th is enlarged. This larger gap allows a significantly larger volume flow of water move through so that the Drain obstacle 8.1, 8.2 regulates itself.

A can be used to fine-tune a rest position Trimming device 14 may be provided, which is the length of the Force storage element 11 and in particular the location of the Outflow obstacles 8.1, 8.2 limited. Furthermore, it should be thought of the spring stiffness or the spring constant or even a preload of the energy storage element 11 mechanically to influence the spring behavior to be able to take.

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

As is also apparent from Figure 2, is below one Lower edge 15 of the drain obstacle 8.1, 8.2 a Opening, in particular a bottom outlet 16 formed, which is slit-like. To that Bottom outlet 16 also belongs to the bottom 4 recessed drain 5. The bottom drain 16 can by a Height adjustment of the at least one drain obstacle 8.1 to 8.3 can be changed.

At an upper edge 17 of the drain obstacle 8.1, 8.2 connects an overflow 18, which has an overflow opening 19 forms. This serves as an additional backup large water intakes, however, correct design of the drainage system is not used.

The water flows up to a maximum of 17 Drain obstacles 8.1, 8.2.

The operation of the present embodiment is the following:

Water, sewage, rainwater or the like flows over the Channel inlet 6 in channel 1, so with small quantities the water through the drain 5, in particular Dry weather drain directed. If the water level rises, so it flows through the complete bottom outlet 16 and at least partially the gap 12.

If the water rises sharply, the water in the Accumulate vestibule 13, with a specific one Pressurizing the discharge obstacles 8.1, 8.2 Give up force storage elements 11 in flow direction X. and swing up.

As a result, the gap 12 is opened continuously and leaves a larger amount of water in the downstream channel 1 inflow. This results in a drainage delay Retention spaces or backwater spaces are formed. This can rainwater treatment.

In addition, drain peaks are reduced as a result, unwanted backlogs are prevented and Retention spaces made usable.

In the present invention, however, it is also important that regulation and control, and in particular influencing the water quantities, by means of the pressurized swinging open of the discharge obstacles 8.1, 8.2 takes place purely mechanically. This allows drainage systems R _{1 of} this type to be manufactured, maintained and regulated very cost-effectively.

Within the scope of the present invention it should also lie that for example, the energy storage elements 11 Torsion spring elements, coil spring elements or the like. Replaced can also be arranged in the area of the joints 9 could be. There is no limit to the invention here his.

Included in the present invention is that for example, only a single drain obstacle 8.1 or 8.2 used in channel 1 in the manner described above is. The gap 12 can then between the Channel inner wall 10 of the channel wall 2 and the plate element be educated. This can also be narrow or in any desired width as a basic setting be preset. The way it works is the above described.

In a further exemplary embodiment of the present invention according to FIG. 3, an outflow system R ₂ is shown, which is constructed accordingly in the manner described above. Essentially, the individual components are not discussed again here. What is different, however, is that an outlet obstacle 8.3 is formed on one side by one of the two channel walls 2 from a plurality of elements 20.1 to 20.3. The first element 20.1 extends into the channel 1 at an angle α of approximately 0 ° to 90 °, the element 20.1 being set at an angle in the flow direction X.

Following the preferably plate-like element 20.1 connects an arch-like element 20.2. about Connecting joints 21 are the elements 20.1, 20.2 jointed together.

After the element 20.2 closes like a plate formed element 20.3, preferably slightly inclined to Channel wall 2 in the direction of flow, in particular for Channel inner wall 10 and opens into one Guide rail 22 and is there via a roller element 23 movably mounted. The roller element 23 can be a wheel, Gear or the like.

If water, waste water or the like is now supplied to channel 1, so is a pressure on the flat element 20.1 exercised when the water level in channel 1 rises. As a result, the gap 12, which is between the element 20.2 and the channel inner wall 10 is formed by Moving the drain obstacle 8.3, in particular by end method of element 20.3 in the Guide rail 22 in the flow direction X, as in Figure 3 is shown in broken lines, enlarged. A bigger one Amount of water can flow in.

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

On the other hand, the energy storage element 11 is a Locking device 24, for example a definable Gear, wheel or the like in the guide rail 22 changeable. This can influence the location of the Elements 20.3 and in particular on a bias of the Force storage element 11 are taken.

Within the scope of the present invention it should also lie that two such discharge obstacles 8.3, according to the Embodiment according to Figure 1 also opposite can be arranged around a preferably central arranged gap 12 in the manner described above change.

The present inventive concept is also intended to encompass two opposite discharge obstacles 8.1, 8.2 and 8.3 to be provided in channel 1, which also outside of one common level E, for example offset in the channel are arranged.

FIG. 4 shows a similar cross section corresponding to FIG. 2, the bottom outlet 16 being formed below the lower edge 15 of the drain obstacle 8.3 and the overflow 18 with overflow opening 19 being provided above the upper edge 17. However, the gap 12 is formed between the channel inner wall 10 and the arch-like element 20.2.
