The invention relates to hydraulic engineering, and in particular to structures for complex water treatment from driftwood, debris, drawn and part of the suspended sediments in the water intake on systems with a closed pipeline network.

A device for clarification of water, comprising a housing with a discharge channel, a spiral chamber located inside the housing and is made in the form of an overflow wall, the inlet channel connected to the input of a spiral chamber, and a wash pipe connected to promiseme the hole in the bottom of the spiral chamber, while vodoprovidna wall defined by coil spiral of Archimedes in the range of the rotation angle of the radius vector, and washing the hole is located at the pole of this spiral (USSR author's certificate No. 1330254, CL EV 8/02, 1985).

The disadvantages of this device due to its complex structure, including spillway wall, defined by the spiral of Archimedes within the angle, and the complexity of its hydraulic calculation. Low reliability is a consequence of the receipt of driftwood and rubbish, because his work is only preventing the invasion of water intake of sediment transported the intake channel. Thus, this solution does not protect the intake from being hit by driftwood, debris and part of the suspended nanoco is. In addition, the need for visual control of a suitable water flow with driftwood and debris; the lack of control over the effectiveness of such residues, i.e. the fin, debris and suspended sediment that are not protected in a vertical attitude and not going any device. The problem here is solved only in one technological cycle - protection from sediment.

A device for protection of water intake from larvae and juvenile fish, including spiral chamber is installed at the bottom of rubottom, which is supplied installed at the end of the regulating chamber with partitions, the front of which is attached closures (USSR author's certificate No. 654733, CL EV 8/02, 1976).

The disadvantages of the known devices:

the limited application of it, as follows, on the one hand, from the main task - to pass fish through rebooted in the lower reach, and, on the other hand, limit the discharge part of the minimum water level (as occurs backwater from downstream);

the lack of over proryvnym hole perfect vortex;

the inability to automatic flushing of the pipeline through the regulation of water in the chamber;

the lack of automatic water level control by regulating the position of the shield (shutter).

Closest in design and the proposed device is packagefile, includes placed between the inlet and outlet sections of the channel settling chamber with a wash gallery, centrifugal clarifier, which is made in the form of a cylindrical chamber with a bottom, made inclined in the direction of the flushing hole camera with a wash gallery made with graded side slopes in the lower part of which there is an inlet opening leaching galleries (USSR author's certificate No. 1546547, CL EV 8/02, 1987).

The disadvantages of this device due to its complex structure, including sections of the spillway and made in the form of tapering downward and to the side section of the spillway ramps with increasing multiple side slopes, 2 cylindrical chamber separately, the shape of the curves of the plates above the entrance ledge, etc. These devices in difficult field conditions with floating debris and transported deposits often fail because of the detention of their fin, shock large fractions of the sediment, which does not allow for reliable uptime facility during its operation. At the same time, exerting a significant influence through a curved plate on the formation of the exciting force to the floating switching in the direction of the flushing holes, it is through the same plate, in the smallest degree affect the intensity bend the bottom and near-bottom sediment.

The purpose of the invention is to simplify the design and improve work efficiency.

This objective is achieved in that in the system of protection of the diversion structure, comprising placed between the inlet and outlet sections of the channel settling chamber with a wash gallery, centrifugal clarifier, which is made from the bottom, made inclined in the direction of the flushing holes, the camera performed with increasing lateral slopes in the lower part of which is located the inlet of the wash galleries, it is equipped with a flat shield gate with a curved visor installed at the entrance to the settling chamber, and wash gallery adjacent to its entrance to the entrance from the outer side of the cylindrical chamber, placed inside the chamber, equipped with additional nozzles, and the second the nozzle is made in the form of a nozzle with zakruchivali flow and create a direct current of water that is connected to the source of the pipeline pressure water and placed coaxially with the vertical axis of the flushing outlet pipe, while the lower edge of the inner cylindrical chamber is located above the bottom of the outer cylindrical chamber, and the input end of the leaching galleries provided with a horizontal peak. In addition, flat panel shutter with a curved visor installed with verticalscrollbarelement and vertically to the longitudinal spillway wall, adjacent to the discharge chamber with a flat shutter, mounted on a discharge channel in the input part.

This embodiment of the system of protection of the diversion structure allows, in comparison with the prototype, to automate the process of securing settling chamber and leaching gallery from the floating impurities and excess water can be discharged through the spillway wall and into the waste chamber, and thence they proceed in the discharge channel, at the entrance of which has a flat shutter. Moreover, the implementation of the protection separately: for floating inclusions - flat shield gate with a curved visor configured to support the maximum design elevation of the water level (overflow), playing the role of "screen". More intense group of bottom and near-bottom sediment, moving between the rising side slopes and coming through the pipeline into the cylindrical chamber at high speed not less than 3 m/s, reaching the nozzle, flows into the washing opening of the discharge line.

The flow rate of the water flowing from the nozzle, rotates secretively flow at the nozzle, and the speed of rotation of secretively flow depends on the size of the nozzle holes, respectively, the thread is twisted. Sediment directly addicted into rotational motion by the height of the inner cylindrical chamber in the direction of the industry is its holes. Thus placing the nozzle with sacrocaudal flow and hydraulic structure flowing into the device flow organizes input photocopiers element so that the sediments are thicker in the bottom are also displayed in the lower horizon (below the lower edges of the camera) and are transported directly in the wash discharge pipe in the lower reach. For a given water discharge with driftwood and debris through the spillway wall is a certain opening of the flat shield gate with a curved visor (screen). Water coming into the camera with a wash gallery through the hole, he goes to the bottom of it, limited graded side slopes, in turn, directed concentrated water flow flat shield gate creates a backwater to the main flow in the inlet channel, creating conditions that increase or decrease as withdrawn and discharged spending, which in turn makes automatic cleaning of driftwood and debris.

Clicking on the camera with a wash gallery, water from the recovered structure, vertical distribution, transporting harvested and suspended sediment that enters the conveying pressure pipeline, while above the entrance end of the tube is placed visor in the form of a horizontal concrete slab-con is Oli or based on hours and slopes with a length of at least 0.25 d Tr. This embodiment of the visor does not require special protivoluchevogo device, as it significantly reduces the curvature of the streams flowing into the tube, and, consequently, the compression of the flow at the entrance and at a certain pressure pipe "samsarajade", begins to work full cross-section. The visor is simple in shape, small in size, so the device it is easier and cheaper than installing special devices.

The clarified water enters the intake manifold and then to the consumer.

On the basis of the interrelation and interdependence of the basic elements of the protection of the diversion structure, creating the conditions for discharge of driftwood, debris, drawn and suspended load.

The proposed protection system intake structure enables multi-protection water intake from the entire range transported in stream water bodies floating debris, sediment and suspended load.

It should be noted that the proposed protection system water intake, according to the author, was not previously known and meets the criterion of "Significant differences".

Figure 1 shows the proposed system protection diversion structure plan; figure 2 - section a-a in figure 1.

Protection system intake structure includes a settling chamber 1, is placed between the inlet and outlet 3 teaching DAMI channel (or pipe). The bottom of the chamber 1 is made in the form of reduction and tapering toward the inlet 4 of the pipe 5, the role of the leaching galleries at the same time, which is supplied with water clarifiers, made in the form of cylindrical chambers 6 and 7. The camera 6 is made on the side with the inlet 8 and the bottom 9, the Central proryvnym hole 10. The camera 7 is placed inside the vertical chamber 6 tank, and paired with the outlet pipe 5. The lower edge of the inner cylindrical chamber 7 is located above the bottom 9 of the outer cylindrical chamber 6. The output of the pipeline 5 in the chamber 7 is a horizontal section of the nozzle 11 and the nozzle 12 with nozzles 13 (one or two nozzles). At the bottom of the chamber 7 are "absorbers" (partitions) 14, which eliminate rotational movement of the water. The bottom 9 of the chamber 6 are inclined in the direction of the flushing holes 10 with a pipe 15 provided with sbresny channel 16. In the upper part of the chamber 6 on the outer side of the discharge pipe 17 is rigidly installed in the well 18 so that its output end of the 19th submerged under the level. For the discharge pipe 17 is line 3 (or channel) of the water management system - user purified water. The visor 20 is held in a horizontal concrete slab - console or resting on the rack and the wall of the side jambs 21. To ensure round t the UBA 5 full cross-section is sufficient to have a horizontal visor 20 of length l to=0,25dTr(where dTr- pipe diameter)located in a plane tangent to the top of the pipe. Between the inlet section of the channel 2 and the settling chamber installed in the guides 22 flat panel shutter 23 with a curved visor 24 to lift 25. The lower edge of the visor panel 24 and the shutter 23 is located above the bottom of the channel 2. At the entrance to the waste chamber 26 is installed downstream wall 27 adjacent to the panel of the shutter 23. Shield shutter 23 with visor 24 is installed with the possibility of vertical movement to the longitudinal spillway wall 27. Emission chamber 26 provided with a discharge channel 16 with the bolt 28 mounted on the discharge channel 16 in the input part.

Protection of the diversion structure is as follows.

When you pass different values of the water flow in the inlet channel 2 is supported by a definite correlation between the findings of the flat panel shutter 23 with a curved visor 24 and the bottom of the channel 2, which is equal to the amount of water enters the settling chamber 1. When this hydraulic structure flowing into the device water flow provides input photocopiers elements 23 and 24 in such a way that the objects floating in the surface layer remain elevated position unchanged and transported (reset) above the protective waters of the receiving elements 23 and 24 through the spillway wall 27 into the chamber 26. The presence of a flat panel shutter 23 with a curved visor 24, separating the fin and debris from settling chamber 1, with a certain (specified) prop transports floating on (grass, leaves, etc.) with excess water through the spillway wall 27 in the waste chamber 26 and then the fin and debris are dumped into the channel 16. This leads to the protection of the cylindrical chambers 6 and 7 from entering them driftwood and debris.

Take to the water consumer water primarily enters the settling chamber 1. The presence of the visor 20 above the pipe 5 and its location in the plane tangent to the top of the pipe, substantially increases the coefficient of discharge, therefore, the throughput of the standpipe increases. Round pipe 5 is in full cross-section (the length of the visor is not less than lto- 0,25 dTr). The device of the visor is easier and cheaper, in comparison, if instead it was introduced some protivougrevoe device. Drawn and suspended sediment, the characteristic size of which does not exceed the size of the nozzle holes 11 and 13 are received in the cylindrical chamber 7, is placed inside the chamber 6 sooon, and where is the intake of pure water in the pipe 17, is rigidly installed in the well 18, the lower end 19 of which is sunk below the level. For the discharge pipe 17 is line 3 (or channel) water C themes consumer purified water.

The flow rate of the water flowing out of the nozzles 11 and 13 in the chamber 7, allows these sediments pass through a horizontal nozzle 11 a somewhat larger size than the size of the nozzle 13. The stream passes through nozzle (riser) 12 in the nozzle 13 and due to the force of the jet of water coming into the camera with a minimum speed of 3 m/s through a pipe 5 through one or two nozzle 13 causes it to rotate. Under pressure to drive water nozzle 13, rotating, turbulizer flow in the chamber 7, intensively rotates in him drawn and suspended sediment and takes her to the conical bottom 9 of the chamber 6 with proryvnym hole 10. Thus, in the presence of "dampers" (partitions) 14, in connection with a reduction in speed of the water, there is a loss of bottom and suspended sediments on the bottom 9 of the chamber 6, the arrest does not occur in the specified niche in the area of the leaching holes 10. The rate of flow of water in the zone of leaching holes increases, and the discharge pipe 15 feeds a discharge channel 16, which is also in the final part is rinsed from the discharge chamber 26. The rise of purified water up facilitates the transport of water into the pipe 17 and out of the well 18 in the pipeline 3.

The speed of rotation of the nozzle 13 and the intensity of the rotation of the water in the chamber 7 is regulated by changing the installation angle of the nozzle and the size of the nozzle 12.

Thus, the conditions for water purification, the conclusion of the stories in the provision of a two-stage water treatment of all types of objects in the top layer and away from the protective-receiving elements 23 and 24 and relative location of the spillway walls 26, as well as the location of the cylindrical chambers 6 and 7 of different geometrical dimensions in the vertical plane with the effect of damping only in the lower part of the chamber 7, and again increase the speed in the zone of leaching holes 10, i.e. by the difference in total head (H), respectively, the difference of the linear high-rise cell sizes 6 and 7.
