Description

Technical Field

[0001] The utility model relates to the technical field of silt removal equipment, in particular to a silt removal device for a water conservancy project. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. The channels of farmland water conservancy projects are generally built with cement stones and the like. The riverbed of such water conservancy project channels is generally narrow and shallow. However, due to the strong wind and sand in the wild, a large amount of silt will be deposited at the bottom of the channel. The accumulated silt will make the riverbed higher and the water flow rate will slow down, affecting irrigation. Therefore, it is necessary to regularly dredge the channel. The dredging device of water conservancy projects in the prior art usually uses a silt pump to pump the silt and water at the bottom of the gate into a separation tank, and the silt is separated from the water by the separation tank. The position of the pipeline for extracting silt is usually fixed relative to the separation tank, and only the silt at the same position of the gate can be extracted. When cleaning the silt in other parts, the dredging device needs to be moved as a whole, so it is very inconvenient during use. Utility Model Content

A sludge pump 4 is arranged on the mounting plate 3, a turntable 34 is rotatably connected to the mounting plate 3, and a gear 35 is fixedly connected to the lower end of the turntable 34, and an electric telescopic rod 39 is arranged on the lower side of the mounting plate 3, and the telescopic end of the electric telescopic rod 39 is fixedly connected to a fixed block 38, and one side of the fixed block 38 is fixedly connected to a rack 36, and the rack 36 is meshed with the gear 35. The electric telescopic rod 39 drives the fixed block 38 to move back and forth horizontally, thereby driving the rack 36 to move horizontally, so that the turntable 34 can be reciprocated by a certain angle. The lower side of the mounting plate 3 is fixedly connected to a fixed plate 37, and one side of the fixed plate 37 is fixedly connected to a linear guide rail, and the fixed block 38 slides back and forth on the linear guide rail. The linear guide rail can ensure smooth movement of the fixed plate 37, thereby improving stability during movement. Both ends of the fixed plate 37 are fixedly connected to the limit plates 30, and the limit plates 30 can limit the moving distance of the fixed plate 37, thereby preventing the turntable 34 from rotating at an excessive angle.

[0018] A sludge suction pipe 32 is installed on the turntable 34, one end of the sludge suction pipe 32 is equipped with a sludge suction terminal 33, the other end of the sludge suction pipe 32 is connected to the inlet of the sludge pump 4 through a first hose 41, the outlet of the sludge pump 4 is connected to the standpipe 5 through a second hose 42, and the standpipe 5 extends into the filter box 2.

The sludge pump 4 is started to pump the sludge at the bottom of the hydraulic gate together with the water into the filter box 2. After settling in the filter box 2 for a period of time, the upper supernatant is discharged from the drain pipe, and the sludge remains in the filter box 2. In this way, the sludge in the gate is cleaned. The electric telescopic rod 39 drives the turntable 34 to reciprocate, and the sludge pipe 32 swings with the reciprocating rotation of the turntable 34, so that the position of the sludge suction end 33 in the hydraulic gate can be changed, so that the sludge at different positions in the hydraulic gate can be cleaned.

[0020] When there is too much sludge in the filter box 2, it is necessary to discharge the sludge in the filter box 2.
