The invention relates to hydraulic engineering, namely, devices to prevent litter in streams of various household purposes.

Known seroochistki device watercourses, including power and water channels, the filter element is installed between power and water channels can be rotated from a drive around a horizontal axis located transversely of power channel parallel to its bottom, gallery and waste collecting device (USSR Author's certificate No. 1150292, CL EV 5/08, 1985).

The disadvantages of this device due to its complex structure, including motoresaconcagua grid with movable elements using ropes, blocks, respectively bearing rotation, tanks, floats, etc. Low reliability is a consequence of complex structures. In addition, you must install moderatedysthymia trays. While large inclusions in the form of stone and floating debris can be quickly assembled on the grid and create a back pressure in the channel, creating pressure on the grid. All of this allows us to provide reliable continuous operation of the device during its operation. This lack of efficiency sorochintsi also lies in the fact that only delayed the floating debris and sediment trash constant is about accumulating in front of the device and requires periodic cleaning of other means of mechanization.

The closest in design to the proposed device is seroochistki device, including power and water channels, the filter element is installed between power and water channels can be rotated from a drive around a horizontal axis located across the water conveyance channel parallel to its bottom, gallery and waste water-intake hole. In addition, it is provided with a waterproof plate, located across power channel, one edge of which is attached to the axis, is made hollow and dead-ends, and the other edge of the plate is connected with the lower face of the filter element, curved on the arc of a circle, grid mounted in the inlet section of the water intake holes made in the middle part of the hollow axis, two drain Windows, made in the wall of the hollow axis, and a ball valve that communicates with the drain Windows, and the drive of the filter element made in the form mounted on the cantilever part of the hollow axis of the vessel with an inner wall, with the drain open located in the inner cavity of the container, and the partition is attached to the hollow axis between the drain Windows (SU 1631110. CL E02B 5/08, 1991).

A disadvantage of the known device is its complexity due to the presence of two tanks with siphons and Sadi the kami manually the hollow axis with the net, many articulated gears etc. These devices in difficult field conditions with high humidity and dust due to the ingress of large litter of different species often fail, which does not allow for reliable continuous operation of the device during its operation. In addition, in the so-called "pocket" of the filter element can receive a large amount of sediment is a major Sora (stone, gravel, grass, leaves etc), which dramatically increases the weight of the filter element, resulting discharged into the lower reach of the channel large water consumption, and bandwidth of the filter element decreases drastically disrupted irrigation equipment. In this case, the tank is also violated, i.e. it is necessary to apply more force to rotate the filter element, as well as difficulties arise in the calculation of the two cavities each tank separately. It should also be noted that the lack of effectiveness of Sorochyntsi also lies in the fact that only delayed the floating debris, and residual constantly stored in the device and may occur Calmette inside the element. Another drawback is that the bottom of the transit channel requires a large cavities, otherwise debris will flow in the intake channel side waterproof lane the villages at the time of washing the filter element (upper position), i.e. reverse flow of water from the downstream channel is flooding (suction).

The purpose of the invention is to simplify the construction, increase reliability and quality of cleaning.

This objective is achieved in that the device for purification of water from a large litter, including power and water channels, the filter element is installed between power and water channels can be rotated from a drive around a horizontal axis located transversely of power channel parallel to its bottom, the gallery and the water intake hole, connected by pipeline with the actuator of the filter element and the filter element is curved on the arc of a circle, equipped with a waterproof plate, characterized in that it is provided with a limiter upper position of the filter element in the form attached to the filter element two plates on the sides parallel to the walls of the water conveyance channel, the front part of which is attached plane with the slit to the edge of the horizontal plate in contact with the console bottom of the inlet channel, and the rear part is attached to the horizontal axis of the retaining plate, attached to the downstream edge of the filter element, and a retaining plate is located on a slope in the direction of transit of the canal. Thus, the filter element is abien two broad teeth with curved ends parallel to the water conveyance system and attached to the grid, above the filter element and the grating is curved in the longitudinal vertical plane shape and facing the concave side of the filter element, and the slot in the plates of the filter element is installed coaxially Sinaloa the end of the sickle-shaped teeth and are the last stop its upper position. In the filter element in place of connection to the retaining plate is made the hole with the attached sealing plate. In addition, the side plate of the filter element is made in terms of wedge-shaped, tapering towards the back wall of the gallery. While it has a waterproof plate that is installed with the possibility of interacting with the console bottom of the inlet channel from the bottom of the gallery and at the same time is an additional limiter filter element in the upper position. In addition, in order to reduce the load on the concave side of the filter element, a grating with a couple of items has in their lower position, the limiter in the form of strengthened transverse wall located at the bottom of the inlet channel prior to the filtration element.

This design of the device for purification of water from a large litter provides the abstraction of water transported through the channel, which, flowing through the grid and the filter element is large and small debris is discharged into the lower reach of the transit channel, and the treated water enters the gallery to the consumer. Even when backwater water in the presence of a retaining plate attached in front of the outlet with the sealing plate in the form of rubber, carrying sediment and floating debris to pass into the lower reach of the transit channel, while water continues to flow through the grate and filter element in the gallery to the consumer by creating backwater increased the estimated intake water flow. While sickle teeth connected to the grid based on transverse wall secured to the bottom of the inlet channel before a filter element, in the down position remove the cargo weight above the filter element, i.e. the moment of forces from the pressure of large Sora and lattice virtually no effect on the bandwidth of the cells of the filter element. In addition, the bending of the lattice is located at some distance from the outer surface of the filter element. Thus, an automatic washing large litter.

If a forced rotation of the filter element in the upper position and when the clogging member, you need to put a little effort in the initial separation of the filter element from the console part of the bottom of the inlet channel for rotation in the upper position. While Napo the water from the inside (opposite side) wall omitted when the latches enhances and accelerates the lifting up of the filter element, accordingly, the curved ends of a Crescent of teeth are the grooves on the constraints of the filter element in the form attached on the sides of the plates, and the waterproof plate with seals on the ends of the covers gallery from receipt of Sora, and the fine fraction of sediments drawn when their revenues are transported continuously through the hole with the sealing plate in the form of rubber. As flushing of the filter element, the latter and the bars are returned to the original position and open the gallery, and the water intake is resumed. If necessary, wash the filter element also lower vertical bars in the inlet channel.

The use of the proposed device in hydraulic structures simplifies and improves the reliability in operation, eliminates the possibility of entering macro-grained rock material and litter by constant washing in the working position.

The practical efficiency of the device is obvious and it fit in with the design of the irrigation equipment.

Device for purification of water from large debris contains a conjugate between an inlet 1 and transit 2 channels, console 3 inlet channel 1, receiving the well 4. Well 4 with a niche 5 is connected with the outlet conduit 6 through the shutter 7. Over the well 4 has a rotating filter element 8 consisting of a set of two side plates 9 and 10, attached to a plane rigidly with a horizontal axis of rotation 11 of the filter element 8 via bearings on the supports 12. The free end of each of the side plates 9 and 10 has a slot 13, and a horizontal plate 14 attached to the plane with the free ends of the plates 9 and 10 and with the end of the filter element 8. In the filter element 8 at the site of attachment to the horizontal axis 11 is made washing hole 15 with the seal 16 (such as rubber), and from the side of the transit channel 2 with a bias in his favor is a retaining plate 17 attached to the filter element 8 along its generatrix transit across the channel 2. The horizontal axis 11 at the site of attachment of the filter element 8 is attached vodonepronitsaemostyu 18, placed in the recess 5 of the well 4. When this cross-section niches 5 corresponds to the cross section of the plate 18. The pairing of the free end of the waterproof plate 18 with the console 3 inlet channel 1, overlying the entrance of the niche 5, by using the horizontal axis 11 simultaneously with the rotation of the filter element 8 (in the washing position). To the axis 11 is attached the handle 19 with the latch 20. Before the console 3, the bottom of the inlet channel 1, can be rotated on a horizontal transverse axis 21 is fixed grating 22, the sides of which are attached to the axis 21 of sickle teeth 23 and 24 with the tab 25 with forced rotation and fixation during the flushing of the filter element 8 in its upper position. Moreover, the free ends of the grating 22 and sickle-shaped teeth 23 and 24 with the tab 25 is connected by a bounding rod 26 located freely on the filter element 8 through bearings 27 and of the conditions of transport on top of the transit flow of water, together with driftwood, debris, part of transported sediments and suspended sediments, characteristic larger than the cell size of the element 8, due to the oscillatory movements of the free ends of the grating 22. At the bottom of the transit channel 2 before the transverse horizontal axis of rotation 11 is arranged transverse groove 28, in which protoplanets pdpo the Naya plate 17 during rotation of the filter element 8. To the axis 21 attached to the arm 29 with the latch 30. The limiter in the form of longitudinal plates 9 and 10 with the slot 13 is wedge-shaped in plan, tapering towards fixing it to the rotation axis 11. At the bottom of the inlet channel 1 front transverse horizontal plate 14 mounted support wall 27, which functions as a stop, with the possibility of contact in the working position of the grating 22 with side sickle teeth 23 and 24. In the inlet channel includes a groove 31 to install the grille 32.

Device for purification of water from a large litter works as follows. Water coming from the inlet channel 1 through the bars 22, is cleared of large stones and large floating debris on the grille and is reset to transit the channel 2. This skid plate 17 creates additional pressure of water above the filter element 8, and part of the water is filtered and falls into the receiving niche 5 well 4 with a high estimated water consumption to the consumer, which can be adjusted by the shutter 7. Cleared of large stones and large Sora filter element 8 due to the presence of the grating 22, which covers its top, does not generate large torques. Its base grille 22 rests on the transverse protrusion in the form of wall 27 and flows through the filter element 8 (cells) greater consumption of water in the recess 5, as a result, the clogging of large litter Otsu is there. In addition, the grille slides on the surface of the filter element 8, providing free rotation when washing the latter. If necessary, wash the element 8 to lock concave side up to the stop of the retaining plate 17, peretaplivanii in the transverse groove 28 in the bottom of the transit channel 2, simultaneously rotates the waterproof plate 18 and fixed console 3 in the recess 5, providing overlapping niches 5. When the element 8 reaches the top of his position, the free ends of the sickle-shaped teeth 23 and 24, the grating 22 also climb up the ledges 25 is fixed in the slot 13 and the filter element 8 is fixed in the upper position, the holding element 8 is stationary. Thus the free ends of the grating 22 are based on the plate 14 in the upper position. In this case, it also provides washing and through the opening 15 with the seal 16 in the same thread. Freed waterproof plate 18 from the current efforts at her pressure possible deposited and remaining fine sediment. The rotating element 8 and the plate 18 is carried out by the handle 19 is lowered, the latch 20. After washing removed from engagement sickle teeth 23 and 24 from the slots 13 of the plates 9 and 10, the element 8 and the plate 18 will return to its original position and the water intake is resumed. The rotation of the grating 22, sickle-shaped teeth 23 and 24 also assests the Ute arm 29 is lowered, the latch 30 on the transverse ledge 27.

The proposed device does not require large energy consumption in the work when cleaning up large stones and rubbish from the grille and bottom sediments freely pass in transit the canal. The presence of the retaining wall at the end of the element 8 contributes podporu water before the element 8 increases the flow through the last cell.

The advantage in comparison with the prototype lies in the simplicity of construction, high operational reliability due to the absence of complex mechanical drive elements and moving parts capacity with loss of water to discharge may be reduced to not less than 10-15%.
