Description

Technical Field

[0001] The utility model relates to the field of water conservancy facilities, in particular to a water conservancy culvert silt clearing device. Background Art

[0002] Culverts are structures for discharging and diverting water inside dikes and dams. They work together with river dikes and drainage and water storage projects during flood season to control water flow. Culvert gates are gate valves that can control the flow of water in channels and culverts. In order to maintain the water retaining and discharging functions of culvert gates, silt removal is required on a regular basis.

[0003] The patent document with application number CN202123130674.8 discloses a hydraulic culvert silt clearing device, which uses high-pressure water to flow through a silt clearing pipe with a changed angle to impact and clear the silt on one side of the gate body. However, when it is necessary to clear the silt away from the gate body, the angle between the silt clearing pipe and the gate body is relatively large. At this time, after the high-pressure water discharged from the silt clearing pipe impacts the silt away from the gate body, part of the silt will move toward the gate body under the blocking effect of the remaining silt, which will cause the silt to flow back and approach the gate body when clearing the silt away from the gate body, resulting in incomplete cleaning of the silt on one side of the gate body.

[0004] The patent document with application number CN201620448135.9 discloses a desilting device for the Yellow River diversion culvert gate. The high-pressure water pump pumps water for pressurization. The high-pressure water filtered by the filter is sent from a hose to a transverse high-pressure water pipe. Through multiple high-pressure nozzles installed on the transverse high-pressure water pipe, the high-pressure water is sprayed to the silt layer accumulated in front of the gate, and the silt accumulated in front of the gate is removed by the impact force of the high-pressure water. The transverse high-pressure water pipe is driven up and down by the traction support system of the water spraying device, which can enable the high-pressure nozzle to implement high-pressure water spraying at different heights, improve the efficiency of removing silt, and prevent silt from silting up again. The traction support system of the water spraying device is a steel wire rope wound by an electric drum, and the up and down movement of the high-pressure water spraying device is controlled by rope traction through a guide pulley. The utility model can realize rapid desilting of the gate, overcome the inconvenience caused by a large amount of manpower desilting, and has high work efficiency. The equipment can only clean the silt near the gate, and it is inconvenient to clean the silt far away from the gate. Utility Model Content
