Abstract

The invention relates to hydraulic engineering and can be used for automatic flushing of canals, water intake structures and sedimentation tanks from sediments. The purpose of the invention is to increase speed and reliability in operation by reducing the effects of sediment in water on the operation of the control device. In the discharge conduit 2 of the supporting structure 1, a shutter 3 is installed with a horizontal axis 4 of rotation connected to a control device made in the form of a lever 16 with a float 6 located in the vessel 8 with a nozzle 10 having a diaphragm 11 with a nozzle and connected to a level sensor 18 sediment, and supply conduit 13. In the absence of sediment in the conduit 2, the nozzle 10 through the sensor 18 is filled with water and the diaphragm 11 closes the conduit 13. The float 6 is in the lower position and the shutter 3 is closed. When the conduit 2 is filled with sediments, the water inflow into the nozzle 10 is stopped, the water from it is drained through the jet, the diaphragm 11 opens the conduit 13 and the tank 5 is filled through the pipe 9 with water. The float 6 opens the shutter 3. The sediment is flushed out of the upstream 15. Then a siphon 19 is charged, the water from the tank 5 is drained and the shutter is closed. 1 hp f-ly, 2 ill.

FIG. /

The invention relates to hydraulic engineering, and more specifically to devices for automatic flushing of canals, water intake structures and sedimentation tanks from sediments.

The purpose of the invention is to increase the speed and reliability of operation by reducing the effects of sediment in the water on the operation of the control device.

FIG. 1 shows the proposed device, a transverse vertical section; in fig. 2 — node 1 in FIG. one.

In the supporting structure 1, a discharge conduit 2, in which a shutter 3 is installed with a horizontal axis 4 of rotation, is connected to the control device. The control device was made in the form of a 15 nepo in the form of a regulating tank 5 with a float 6 and a discharge hole 7, a distributor tank 8, communicated by a pipe 9 with a container 5, a vertical water-filled

sediment the flow of water into the pipe 10 is stopped, the water from the pipe 10 through the nozzle 12 is discharged into the tank 8 and the diaphragm 11 opens the conduit 13. The tank 5 is filled with water, the float 6 raises the lever 16 and the shutter 3 opens. The sediments from the headwater 15 are removed. Then the siphon 19 is charged and the container 5 is emptied. The shutter 3 is closed and the nozzle 10 is refilled with water.

Claims (2)

Claims 1. A device for flushing a hydraulic structure from sediments, including a shutter installed on a wastewater conduit of a retaining structure with a horizontal axis of rotation and a control device containing a lever, a brush, a supply conduit, one end of which is connected to the upstream, and a load level sensor installed-pipe 10, located in the tank 8, 20 waste conduit before the shutter and the valve, made in the form of elastic made in the form of a vertical tube, diaphragm 11 with a jet 12 installed in that, in order to increase the lower part of the nozzle 10 which feeds fast and reliable operation by Argument 13, one end of which is connected through the filter 14 with the headwater 15, and the other end: | is in tank 8 under diaphragm 11, and lever 16, one end of which H1 is hinged to the side of tank 5, the other is pivotally connected through rod 17 with the shutter 3, and the deck 6 is hinged to the middle of the lever 16.
