The invention relates to hydraulic engineering, and in particular to devices for cleaning sediment of water entering a machine irrigation system.

Known fish protection device (ed. St. USSR No. 1011775, E 02 B 8 / 08.1980), including a cylindrical plan chamber with a discharge conduit, in which an annular wall with a mesh upper part, supplying a conduit placed with respect to the inner surface of the wall, and a fish outlet connected to the center of the chamber, moreover, to increase the efficiency of fish protection, the annular wall has a broken outline formed by alternately arranged radial and spiral sections.

The disadvantages of the known device include: x

the formation in the mating areas of the radial 4 and spiral 5 sections of the wall 3 of stagnant non-washable sections for the accumulation of floating impurities, where bottom deposits are possible that interfere with the functioning of the device;

trauma as a result of collisions and contact with impurities and young fish litter when it is directed to the central hole in the bottom of chamber 1. transporting it through fish drain 7 ;,

unintended permanent or periodic cleaning of the upper mesh portion of the annular wall 3;

constant energies for diverting juvenile fish back to the water source

The closest to the proposed purpose, technical nature and the achieved result is a sump for auto USSR No. 1350242, cl. E 02 B 8/02, 1985, which is equipped with a float valve mounted on the end of the discharge tube located in the housing section facing the outlet pipe to increase operational reliability,

The disadvantages of the known device: periodic supply of clean water by the sump to the consumer through the outlet pipe 15, which is periodically interrupted during washing of the sump by using the ascending 7 and descending 9 branches of the siphon 8. As a result, air plugs are created in the pipelines with clean water, which reduce the efficiency in operation of the known device and thereby hindering the water supply,

blockage of the inlet of the ascending branch of the siphon 7 by accumulations of sediments in

the conical part of the sump at window 5 and their colmatization is natural, which can prevent the inclusion of siphon 8 in the work (first) and lead to failure

the suction force of the siphon 8 to raise the applied mass to the entire height of the ascending branch 7 of the siphon 8, i.e. to a height m of the inlet of the siphon 8 up to the hood 10 (secondly);

charging the siphon 8 only when the ascending 7 and descending 9 branches of the siphon 8 and hood 10 are completely filled with water.

The purpose of the invention is to increase the efficiency of sand gravel work.

This goal is achieved in that in a sand gravel box including a receiving tank of cylindrical shape for

sediment collector with an inclined bottom communicated with the inlet channel and the discharge manifold, the sediment collection tank is equipped with an oblique annular ring secured to the inclined bottom and

has an additional receiving tank installed in its internal cavity, made in the form of a truncated cone with a pyramidal divider in its center, coaxially located with an annular shell, npl llfo Mr The additional receiving tank has a radially curved upper edge, and the body of the discharge manifold has a cone shape, upper edge which is connected to the upper edge of the additional receiving tank and forms a circular siphon with the walls of the main receiving tank. In addition to Tdro, a flushing channel is made in the center of the main tank, the discharge collector is equipped with a clean water pipe connected to it, and the supply channel is fixed coaxially with the main receiving tank.

This embodiment of the sand gravel will increase its efficiency in operation due to the fact that sand and gravel, drawn by the flow, are divided by a pyramidal divider around the circumference of the receiving tank and sent to the washing channel by acting on them annular

shell, creating an obstacle (shielding) the movement of sand and gravel up. In addition, the quality of the treated water is improved due to the effect of siphoning water in the zone between the walls of the main and additional receiving tanks, when water flows over the upper annular edge of the cylindrical tank, which cuts off the small-fraction part of sediment. Compared with the prototype, the proposed device operates in a mode of continuous supply of clarified water to the consumer.

The proposed sand gravel is more practical to manufacture and easier to install; structural performance in comparison, 5 for example, with hydrocyclones and well-known sand gravel traps according to auth. USSR No. 184187, 367895, 544473, 816558, 823647, 882942, 886998, 1330254, 1392188. 1456234, 1546547.10

In FIG. 1 shows a top view (plan); in FIG. 2 is a longitudinal section AA in FIG. 1.

The sand-gravel trap includes a receiving tank 1 of a cylindrical shape for collecting sediments, equipped with an oblique annular shell 3 fixed to the slope bottom 2 and has an additional receiving tank 4 installed in its inner cavity, made in the form of a truncated cone with a pyramidal 20 divider 5 in its center , coaxially located with the annular shell 3, while the additional receiving tank 4 has a radially bent upper edge 6, and the body of the waste collector 7 has a 25 cone shape, the upper edge 8 of which о is connected to the upper edge 6 of the additional receiving tank 4 and forms a circular siphon 9 with the walls of the main receiving tank 1. In addition, a washing channel 10 is made in the center of the main tank 1, the discharge manifold 7 is equipped with a clean water pipe connected to it 11, and the supply channel 12 is fixed coaxially with the main receiving tank 35 of capacity 1. Between the walls of the oblique ring shell 3 and the receiving tank 1 of a cylindrical shape, a zone of calm state of water 13 is formed.

The sand gravel works as follows1–40.

Water with sand and gravel enters from the inlet channel 12 into a receiving tank 1 of a cylindrical shape for collecting sediment and is distributed around its circumference by a pyramidal divider 5, which prevents the accumulation of sand and gravel in the center and ensures reliable permanent washing of impurities along the inclined bottom 2 into the washing channel 10. When the additional 4 and main cylindrical 1 receiving tanks are fully filled with water, the overflow speed of water through the upper edge (not indicated) of the main cylindrical receiving tank is 1 tbsp. lysed ba- 55, part of small fraction of suspended sediment settles in the restful state zone 13 nor water, which if necessary washed away (break) the reverse current.

The oblique ring shell is an obstacle to moving sand upstream (coarse fraction of suspended sediment). 3, and the fine fraction of suspended sediments is a combination of factors (the wall height of the main cylindrical receiving tank 1 is optimally selected, the calm behavior of water in zone 13 between the annular shell 3 and the wall of the main tank 1, the presence of upper (bent) edges 6 and 8 of the additional receiving tank 4 and the discharge collector 7, respectively), the water to be purified passes in the gap between the walls of the additional 4 and the main 1 receiving tanks, i.e. in the ascending branch of the circular siphon 9, the purified water is poured over the upper edge (not indicated) of the main receiving tank 1 and collected in the body of the waste collector 7, i.e. in the descending branch of the circular siphon 9, from which pure water is sent to the consumer via line 11.

The economic efficiency from the application of the proposed sand gravel is composed of

simplification of the process of separating sand and gravel from water, thereby improving the quality of treated water and reducing maintenance costs;

simplifying the design of the device, resulting in reduced manufacturing costs.
