Description

Technical Field

[0001] This utility model relates to the field of river dredging technology, specifically to a river dredging and sludge suction device for water environment management. Background Technology

[0002] In the field of water environment management engineering, the unobstructed flow of waterways is crucial for flood control, drainage, water resource allocation, and ecological environment maintenance. However, over time, large amounts of silt often accumulate in waterways. This prevents waterways from effectively and promptly draining floodwaters during periods of high water volume, increasing the risk of flooding. Simultaneously, silt accumulation negatively impacts the river's ecological environment, necessitating regular dredging. Current dredging equipment typically uses a ship as a base, incorporating a sludge pump as its core, supplemented by modules for silt dewatering. However, in actual operation, to improve the stability of silt removal, an isolation mesh cover is usually installed at the sludge pump's suction inlet to effectively prevent debris such as garbage and branches from entering the pump. However, after a long period of operation, the dredging vessel needs to regularly clean the debris on the suction hood to prevent it from clogging the hood holes and affecting the amount of sludge sucked in by the suction pump. The cleaning operation is quite cumbersome and affects the overall efficiency of the sludge cleaning operation. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a river dredging and sludge suction device for water environment management, which solves the problem that the suction hood of existing river dredging devices is prone to clogging and requires frequent cleaning, thus affecting the overall efficiency of dredging operations.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a river dredging and sludge suction device for water environment management, comprising a sludge suction boat hull and a sludge suction pump mounted on the hull. The inlet end of the sludge suction pump is connected to a sludge suction pipe, and the outlet end of the sludge suction pump is connected to a filter press separation mechanism on the hull. One end of the sludge suction pipe is provided with a mounting base, and a metal grid mesh cover is mounted on the mounting base. A protective frame is provided on the outside of the metal grid mesh cover, and a waterproof motor is installed inside the protective frame. A transmission connection component is installed at the output end of the waterproof motor, and a rotary unblocking component and a sludge disturbance component are installed at the output end of the transmission connection component.

One end of the main shaft is connected to the output end of a waterproof motor, and the other end is connected to a rotary unblocking assembly. Both sides of the main shaft are connected to an output shaft via belt connectors. One end of the output shaft is connected to a sludge disturbance assembly.

[0006] The aforementioned belt connector includes two driving pulleys fixedly mounted on the main shaft, a driven pulley fixedly mounted on the output shaft, and a transmission belt sleeved between the driving pulley and the driven pulley.

[0007] The aforementioned rotary unblocking assembly includes a connecting seat located at the upper end of the main shaft, a U-shaped frame on the connecting seat, a rigid cleaning brush located inside the U-shaped frame, and the bristles of the rigid cleaning brush being in contact with the outer wall of the metal grid cover.

[0009] The aforementioned waterproof motor is connected to the controller on the hull via a waterproof wire, which is then bound and fixed to the mud suction pipe.

[0010] This utility model provides a river dredging and sludge suction device for water environment management. It offers the following advantages: It improves upon existing sludge suction vessels by installing a mounting base at the end of the suction pipe to secure a metal grid cover and a protective frame.

A transmission connection component is installed at the output end of the waterproof motor 8, and a rotary unclogging component and a silt disturbance component are installed at the output end of the transmission connection component. This improves upon existing suction hulls by providing a mounting base 5 at the end of the suction pipe 3 for fixing the metal grid cover. The net and protective frame 7 effectively prevent large debris such as dead branches from entering the metal grid cover 6. The metal grid cover effectively intercepts debris in the sludge, preventing it from entering the suction pipe 3 and affecting the normal operation of the suction pump 2. A waterproof motor 8 is installed inside the protective frame 7. The waterproof motor 8 is used as the power source to centrally control the rotary unblocking component and the sludge disturbance component through the transmission connection component. The sludge disturbance component disturbs the sludge around the protective frame 7, thereby improving the suction efficiency. The rotary unblocking component scrapes and cleans the outer wall of the metal grid cover 6, thereby effectively preventing debris from clogging the mesh on the metal grid cover 6, ensuring the smooth and efficient operation of the suction. The structure is compact and highly reliable, effectively reducing cleaning and maintenance costs.

Simultaneously, the suction pump 2 is started, and the waterproof motor 8 inside the protective frame 7 is also started. The drive end of the waterproof motor 8 rotates, which in turn drives the main shaft 10 to rotate. During the rotation of the main shaft 10, the driving pulley 12 on it rotates.
