Description

Technical Field

[0001] The invention relates to the technical field of channel drainage equipment for water conservancy project construction, in particular to a channel drainage device for water conservancy project construction. Background Art

[0002] Construction channels are the pathways used to transport, distribute, and discharge water within water conservancy projects and are a crucial component of these projects. They can be categorized by material (earthen, concrete, plastic, etc.) and function (water transfer channels, drainage channels, irrigation channels, etc.). Their primary functions include transporting water, regulating water flow, and ensuring the safe operation of water conservancy projects. They can also serve as flood control, drainage, and irrigation.

[0003] The existing channel drainage device used in the construction of water conservancy projects cannot effectively clean up the pumped-out silt and other garbage when draining the channel, and cannot effectively carry out centralized treatment of the silt and garbage that need to be treated. In addition, when the device is working, the silt and other garbage cannot be cleaned in time, which will reduce the working efficiency of the machine and increase the dependence on manual labor, resulting in the need for manual labor to clean up the internal silt in time to avoid affecting the normal operation of the machine. This will cause unnecessary waste of money due to redundant use of manpower, reduced work efficiency and shortened machine life. The inability to effectively treat and collect residual garbage such as silt during the pumping process will cause garbage blockage at the water outlet, further causing blockage of the drain pipe, which will reduce the efficiency of the machine and manually clean up the garbage, resulting in excessive reliance on manpower and reduced work efficiency.

[0018] When the electric push rod of the present invention is in operation, it will drive the fixing plate, welding rod, relay rod and sleeve rod to move forward and backward together. At the same time, the sleeve rod will drive the pull rod to move forward and backward together. When silt and other garbage are pushed into the silt cleaning port, the pull rod will drive the silt extrusion plate to move forward and backward, approaching and moving away from each other, so that the silt and other garbage inside the silt collection box are compressed and squeezed. This will reduce the space occupied by silt and other garbage, so that the silt collection box can collect more silt and other garbage, thereby improving work efficiency and reducing the number of manual cleaning times, better utilizing the device for channel drainage, and further improving the work efficiency of the device.
