TECHNICAL FIELD

[0001] The utility model belongs to the technical field of dredging device, concretely relates to a water distribution outlet dredging device for water conservancy projects. BACKGROUND

[0002] In the field of water conservancy projects, the water distribution outlet is a key link for water distribution, and its smoothness is crucial for the normal operation of the entire water conservancy system. However, over time and under the influence of the natural environment, a large amount of silt and debris, such as sand, stones, and dead branches, often accumulates at the water distribution outlet. The accumulation of these debris can seriously affect the efficiency of water distribution and even cause blockage of the water flow, thereby threatening the safe operation of the water conservancy project. To effectively solve the problem of silt accumulation at the water distribution outlet, the industry has developed various dredging devices, one of which is a combined water distribution outlet dredging device disclosed in CN208650121U. This utility model patent combines multiple dredging components in a novel and ingenious way to achieve efficient cleaning of silt at the water distribution outlet. Additionally, the establishment of a vortex cover effectively reduces the spread of mud during the dredging process. However, despite the excellent performance of the dredging device disclosed in CN208650121U in reducing mud spread during dredging, it still faces some challenges in practical application, particularly when the silt at the water distribution outlet contains large-volume debris such as dead branches. These debris can easily get stuck in the suction pipe, mud pump, or other critical components during the process of being sucked into the dredging device along with the silt, causing blockage of the dredging device and affecting its normal operation. Once the dredging device is blocked, not only will the dredging efficiency be reduced, but the dredging device itself may also be damaged, increasing maintenance costs and downtime. SUMMARY

[0003] To address the above problems, the utility model aims to provide a water distribution outlet dredging device for water conservancy projects that solves the problems raised in the background.

[0004] To achieve the above objectives, the utility model employs the following technical solution: a water distribution outlet dredging device for water conservancy projects, comprising a floating box, a dredging pump, a submersible pump, and a filter cover installed on the floating box. Screw holes are provided on the floating box, and the screw holes are rotatably connected to bolts. The dredging pump is connected to a mud discharge pipe and a suction pipe, while the submersible pump is connected to a water delivery pipe. The other ends of the water delivery pipe and the suction pipe, which are away from the dredging pump, are both connected to a suction head. The suction head is fixedly connected to a filter screen through a vortex cover. A high-pressure jet is provided at the inner end of the suction head, and the high-pressure jet is in communication with the water delivery pipe.

[0005] The utility model has the advantages that: when the utility model is used, it can effectively filter debris, preventing the debris from being sucked into the dredging device, which can cause blockage and affect the normal operation of the dredging work, and can also cause damage to the dredging device itself, thereby increasing maintenance costs and downtime.

[0006] In order to facilitate the suction of mud and the manufacture of mud:

[0007] As a further improvement of the above technical solution: the dredging pump is located at the top end of the floating box, and the submersible pump and the filter cover are both located at the bottom end of the floating box.

[0008] The beneficial effects of the improvement are: the establishment of the dredging pump can facilitate the suction of mud through the mud discharge pipe and the suction pipe; the establishment of the submersible pump can spray the extracted water through the water delivery pipe and the high-pressure nozzle to flush the silt at the bottom of the pipe, so that the silt forms mud for easy suction.

[0009] In order to facilitate the prevention of the submersible pump from sucking in foreign matter by mistake:

[0010] As a further improvement of the above technical solution: the filter cover covers the outer end of the submersible pump, and the bottom end of the floating box on both sides of the submersible pump is provided with a screw hole, and the bolt is screwed through the filter cover and the screw hole.

[0011] The beneficial effects of the improvement are: after the bolt is screwed through the filter cover and the screw hole at the bottom end of the floating box, the filter cover is located at the outer end of the submersible pump, which can isolate and filter the foreign matter mixed in the water when the submersible pump is in the suction working state, so as to avoid being sucked in by mistake, which can easily affect the normal operation of the submersible pump. Similarly, reverse operation can disassemble and replace the filter cover.

[0012] In order to facilitate the prevention of large-area diffusion of mud:

[0013] As a further improvement of the above technical solution: the vortex cover is screwed with the suction port outer wall of the suction head through the internal thread provided on the inner wall of the vortex cover.

[0014] The beneficial effects of the improvement are: after the vortex cover is screwed with the suction head, the installation of the vortex cover is completed, and the water sprayed by the high-pressure nozzle at the inner end of the suction head during the dredging process can form a vortex in the vortex cover, which can flush the silt, so as to prevent the large-area diffusion of mud when the mud in the vortex cover is sucked.

[0015] In order to facilitate the isolation and filtration of foreign matter, and improve the filtration efficiency and reduce the risk of local blockage:

[0016] As a further improvement of the above technical solution: the filter screen is located between the suction head and the vortex cover, and the middle part of the filter screen is outwardly convex in a hemispherical shape.

[0017] The beneficial effect of the improvement is that: through the setting of the filter screen between the suction head and the vortex cover, when the silt suction work is carried out, the filter screen can effectively isolate and filter the sundries mixed in the silt, avoid the sundries from being mistakenly sucked, and easily form blockage, which affects the normal work of the dredging pump, the middle part of the filter screen is outwardly protruding hemispherical, which can increase the surface area of the filter screen, improve the filtering efficiency, and reduce the risk of local blockage.
