Description

Technical Field

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

[0002] Water conservancy projects are constructed to eliminate flood hazards and develop and utilize water resources. Based on their service objectives, they are categorized as flood control projects, agricultural water conservancy projects, hydropower generation projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and coastal reclamation projects. Water conservancy projects that simultaneously serve multiple goals, such as flood control, water supply, irrigation, and power generation, are called comprehensive water conservancy projects. Over time, large amounts of silt and impurities accumulate in the river channels of water conservancy projects, necessitating dredging. Prolonged periods of desilting can easily lead to blockage, reduced water flow, and water pollution. For example, Chinese Patent Publication No. CN216810073U discloses a water conservancy project desilting device, belonging to the technical field of water conservancy project cleaning equipment. The device comprises a movable base and a fixed box mounted on top of the movable base. A sewage pump is mounted within the fixed box. An inlet pipe is attached to the inlet end of the sewage pump, and a flexible hose is provided on one side of the inlet pipe. Multiple support frames are mounted on one side of the fixed box, each of which houses a collection box. A first threaded pipe is mounted on one side of the collection box. The utility model is characterized in that a plurality of support frames are installed on one side of a fixed box through the arrangement of a support frame, a collection box, a first threaded tube, a sealing sleeve and a second threaded tube, and a collection box for collecting sludge is placed on the support frame. The collection box is connected to the output end of the sewage suction pump through the first threaded tube, the sealing sleeve and the second threaded tube, so that the sludge pumped out by the sewage suction pump is discharged into the collection box, avoiding direct discharge to the shore, thereby reducing pollution to the environment.

[0003] Although the device is equipped with a filter box in front of the collection box to filter water, impurities and solid waste in the sludge, the filtered impurities will clog the filter screen, which requires frequent cleaning or replacement, affecting the dredging efficiency. For this reason, we propose a water conservancy project dredging device to solve the above problems. Utility Model Content
