Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a silt cleaning device for water conservancy projects. Background Technique

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. Water conservancy projects based on surface water usually build river channels. Over time, silt is likely to accumulate at the bottom of the river channels. Excessive silt accumulation will affect the normal operation of water conservancy projects. Therefore, regular silt cleaning is required. In the prior art, the silt cleaning devices usually suck the silt at the bottom of the river channel, carry out simple filter water treatment, and then transport the silt.

[0003] According to Chinese Patent No. CN217204346U, a silt cleaning device for water conservancy projects is disclosed, which includes a vehicle body and a silt cleaning mechanism. A silt box and an L-shaped support rod are installed on the vehicle body. The silt cleaning mechanism is connected to the silt box through a silt pumping assembly. The silt cleaning mechanism includes an inverted U-shaped frame, a motor, and a first rotating shaft and a second rotating shaft connected by a pulley and a belt. The silt pumping assembly includes a silt pump, an L-shaped silt pumping pipe, and a silt inlet pipe. One end of the horizontal pipe of the L-shaped silt pumping pipe is connected to the inlet end of the silt pump, the other end of the horizontal pipe of the L-shaped silt pumping pipe extends into the hollow vertical rod, and the vertical pipe of the L-shaped silt pumping pipe passes through the top plate of the inverted U-shaped frame. By setting the motor, the first rotating shaft, the second rotating shaft, the pulley and the belt, the utility model can drive the stirring blades to rotate, stir the silt in the inverted U-shaped frame, disperse the silt, and facilitate the silt pump to suck and clean the silt, avoiding the blockage of the pumping pump caused by the direct pumping method and affecting the service life of the pumping pump. However, in actual use, the silt cannot be concentrated at the silt pumping pipe orifice after being broken, resulting in low silt pumping efficiency. Content of the Utility Model
