[0002] Dredging is an important part of water conservancy projects. Its main purpose is to remove silt and sediment from water bodies such as rivers, lakes, and reservoirs in order to restore and improve the ecological function and environmental quality of the water bodies.

[0003] Existing dredging devices, such as the dredging component and device for water conservancy projects disclosed in Chinese Patent Publication No. CN220100019U, use a first sewage pipe and multiple collecting pipes to pump sludge from water conservancy projects. However, the partition plate at the bottom of the collecting pipe can obstruct the sludge and prevent efficient agitation of the sludge at the bottom of the water, resulting in a large amount of sludge not being pumped out and affecting the dredging efficiency.

[0004] Therefore, this application provides a dredging device for water conservancy survey, which solves the problem that existing dredging devices cannot efficiently agitate sludge, thus affecting sludge suction efficiency. Utility Model Content

[0007] The stirring assembly includes a hollow stirring rod, the lower end of which is connected to an aeration pipe. A conveying fan blade is provided on the upper side of the aeration pipe, and the conveying fan blade and the aeration pipe are located on the lower side of the sludge removal hood.

[0008] As an optimization, the upper end of the hollow stirring rod is connected to a stirring motor, which is fixedly connected to the sludge removal pipe. The stirring motor is a waterproof motor.

[0009] As an optimization, the upper end of the hollow stirring rod is connected to a high-pressure air supply pipe, the lower end of the hollow stirring rod is a closed end, the aeration pipe is connected to the interior of the hollow stirring rod, and the aeration pipe is equipped with an aeration one-way valve.

[0010] As an optimization, the opening of the sludge removal hood is set downwards, and the maximum diameter of the sludge removal hood is greater than the maximum diameter of the conveying fan blades.

[0011] As an optimization, the sludge removal pipe is an L-shaped pipe, the stirring assembly is disposed in the vertical section of the sludge removal pipe, a fixed bearing is disposed inside the vertical section of the sludge removal pipe, and the hollow stirring rod passes through the inner ring of the fixed bearing;

[0012] The hollow stirring rod is equipped with a spiral conveying blade on its exterior, and the spiral conveying blade is located on the upper side of the sludge removal cover.

[0013] As an optimization, the telescopic assembly includes a telescopic rod, the fixed end of which is installed on the dredging facility, and the extended end of which is connected to the dredging cover.

[0014] This invention relates to a dredging device for water conservancy surveys, which has the following advantages:

[0015] This application incorporates a hollow stirring rod inside the dredging pipe. The hollow stirring rod aerates the sludge at the bottom of the water, causing it to rise and churn. The dredging hood shields the sludge and water from turbulence, preventing large-scale sludge diffusion. Furthermore, the hollow stirring rod agitates and transports the sludge, effectively improving dredging efficiency and effectiveness. Attached Figure Description
