[0028] A suction and filtration dust collection assembly is installed at the bottom of the cover plate 4, and an exhaust fan 405 for suctioning the inside of the suction and filtration dust collection assembly is embedded and fixed at the top of the cover plate 4. The top of the cover plate 4 has an embedding hole for fixed connection with the outside of the exhaust fan 405. A steel wire rust removal brush 403 for friction rust removal on the outside of the hydraulic construction pipeline is fixedly installed at the bottom of the suction and filtration dust collection assembly. The suction and filtration dust collection assembly is used to drive the steel wire rust removal brush 403 downward to contact the hydraulic construction pipeline when the cover plate 4 moves down, and to grind and remove rust from the rotating hydraulic construction pipeline. It is also used to suction, filter and collect the dust generated by grinding and rust removal when the exhaust fan 405 is started.

[0029] Specifically, the clamping and rotating support assembly includes a rectangular sliding sleeve 102 slidably sleeved on the outside of the worktable 1. A second electric telescopic rod 101 with its extended end fixedly connected to the left side of the rectangular sliding sleeve 102 is fixedly installed at the bottom of the worktable 1. An L-shaped rod 103 is fixedly connected to the top of the rectangular sliding sleeve 102. A drive motor 104 is fixedly installed on the left side of the U-shaped support plate 2. Two symmetrically arranged conical clamping blocks 105 are provided on the inner side of the U-shaped support plate 2. The right end of the output shaft of the drive motor 104 is connected to the left conical clamping block 105. The left side is fixedly connected, and a through hole is opened on the inner wall of the left side of the U-shaped support plate 2. A second bearing is fixedly sleeved in the through hole. The inner ring of the second bearing is fixedly fitted to the outer side of the output shaft of the drive motor 104, so as to achieve the effect of rotating the output shaft of the drive motor 104. The left end of the L-shaped rod 103 is rotatably installed on the right side of the right tapered clamp 105. The right side of the right tapered clamp 105 is fixedly connected to the right side of the first bearing, and the inner ring of the first bearing is fixedly fitted to the outer side of the L-shaped rod 103. This mechanism facilitates the rotational installation of the right-side conical clamp 105. The rectangular sliding sleeve 102, the second electric telescopic rod 101, the L-shaped rod 103, the conical clamp 105, and the drive motor 104 work together to attach the left-end clamp of the hydraulic construction pipeline to the outside of the left-side conical clamp 105. Then, the second electric telescopic rod 101 is activated in the reverse direction, driving the rectangular sliding sleeve 102 to move to the left. The rectangular sliding sleeve 102, through the L-shaped rod 103, drives the right-side conical clamp 105 to the left, engaging it within the right end of the hydraulic construction pipeline. The conical clamp 105 is squeezed to the side to achieve the effect of clamping and supporting the water conservancy construction pipeline. The conical structure of the conical clamp 105 makes it easy to clamp and support various specifications of water conservancy construction pipelines. The drive motor 104 drives the left conical clamp 105 to rotate, which in turn drives the clamped water conservancy construction pipeline to rotate. The water conservancy construction pipeline drives the right conical clamp 105 to rotate synchronously, thus achieving the effect of clamping and supporting the water conservancy construction pipeline from both ends and driving its rotation.

[0030] Furthermore, the vertical guide support assembly includes a U-shaped plate 301 fixedly connected to the extended end of the first electric telescopic rod 3. The bottom of the U-shaped plate 301 is fixedly connected to the top of the cover plate 4. Two vertical guide tubes 303 are fixedly connected to both sides of the top of the cover plate 4. Vertical guide rods 302 are slidably sleeved inside the vertical guide tubes 303. The top ends of the four vertical guide rods 302 are fixedly connected to the bottom of the moving end of the electric slide rail 201. The U-shaped plate 301, vertical guide tubes 303 and vertical guide rods 302 cooperate to drive the cover plate 4 to move up and down through the first electric telescopic rod 3 via the U-shaped plate 301. The cover plate 4 drives the four vertical guide tubes 303 to slide vertically on the corresponding vertical guide rods 302 to perform vertical guiding work.

[0031] Furthermore, the suction filter dust collection assembly includes a slag collection box 401 threadedly fixed to the bottom of the cover plate 4, a steel wire rust removal brush 403 fixedly installed in the middle of the bottom of the slag collection box 401, and multiple inclined L-shaped suction pipes 402 embedded and fixed on both sides of the bottom of the slag collection box 401. The bottom end of the L-shaped suction pipe 402 is inclined towards the steel wire rust removal brush 403, and the top end of the L-shaped suction pipe 402 extends into the slag collection box 401. A stainless steel filter cartridge 4 is fixedly connected to the bottom inner wall of the slag collection box 401 and is in movable contact with the bottom of the cover plate 4. 04. The bottom of the exhaust fan 405 is a suction port that connects to the interior of the stainless steel filter cartridge 404. The top of the slag collection box 401 has two threaded grooves on both sides, with knob-type bolts threaded into these grooves. The cover plate 4 is threaded onto four knob-type bolts. The top of the cover plate 4 has four threaded holes that connect to the corresponding knob-type bolts. These four knob-type bolts are used to fix or unlock the slag collection box 401, allowing for subsequent disassembly and cleaning of the interior. The slag collection box 401 and the L-shaped dust collector... The pipe 402 and the stainless steel filter cartridge 404 work together. When the cover plate 4 moves down, the slag collection box 401 drives the wire rust removal brush 403 downward to come into contact with the outer side of the water conservancy construction pipeline. When the water conservancy construction pipeline rotates, it forms friction with the wire rust removal brush 403, achieving the effect of grinding and removing rust from the water conservancy construction pipeline. The electric slide rail 201 drives the cover plate 4 to move right and left in sequence through the first electric telescopic rod 3 and the U-shaped plate 301. The cover plate 4, through the slag collection box 401, drives the wire rust removal brush 403 to move right and left, thus moving and grinding the entire outer side of the water conservancy construction pipeline. When the rust removal process is initiated, the exhaust fan 405 draws dust from the inside of the slag collection box 401. The slag collection box 401 uses multiple L-shaped dust suction pipes 402 to draw dust generated at the rust removal location. The drawn-in dust is filtered and collected in the slag collection box 401 by the stainless steel filter cartridge 404. Furthermore, the L-shaped dust suction pipes 402 move laterally in conjunction with the steel wire rust removal brush 403, achieving a synchronous and stable suction, filtration, and collection of dust generated during rust removal. This reduces the phenomenon of large amounts of dust drifting outwards, polluting the on-site environment, and harming personnel, thus improving the environmental friendliness of the process.

[0032] The usage method of this embodiment is as follows: When using the rust removal device for the outer surface of the water conservancy construction pipeline, firstly, attach the left end sleeve of the water conservancy construction pipeline to the outside of the left conical clamp 105. Then, reverse the operation of the second electric telescopic rod 101 to drive the rectangular sliding sleeve 102 to slide to the left on the workbench 1. The rectangular sliding sleeve 102, through the L-shaped rod 103, drives the right conical clamp 105 to the left to clamp into the right end of the water conservancy construction pipeline and squeeze it tightly. Start the drive motor 104 to drive the left conical clamp 105 to rotate. The left conical clamp 105 drives the clamped hydraulic construction pipeline to rotate, and the hydraulic construction pipeline drives the right conical clamp 105 to rotate synchronously, realizing the effect of clamping and supporting the hydraulic construction pipeline from both ends and driving its rotation. The conical structure of the clamp 105 makes it easy to clamp and support hydraulic construction pipelines of various specifications. The right conical clamp 105 can move laterally, making it easy to clamp and support hydraulic construction pipelines of various lengths, thus improving its applicability.

[0033] The first electric telescopic rod 3 and the exhaust fan 405 are started in the forward direction. The first electric telescopic rod 3 drives the cover plate 4 to move downward through the U-shaped plate 301. The cover plate 4 drives the four vertical guide tubes 303 to slide vertically on the corresponding vertical guide rods 302 to perform vertical guiding work. At the same time, the cover plate 4 drives the steel wire rust removal brush 403 downward through the slag collection box 401 to fit against the outside of the water conservancy construction pipeline. When the water conservancy construction pipeline rotates, it forms friction with the steel wire rust removal brush 403 to achieve the effect of grinding and removing rust from the water conservancy construction pipeline. During grinding and rust removal, the electric slide rail 201 is turned on so that it drives the cover plate 4 to move right and left in sequence through the first electric telescopic rod 3 and the U-shaped plate 301. The cover plate 4 drives the steel wire rust removal brush 403 to move right and left through the slag collection box 401 to perform moving grinding and rust removal work on the entire outside of the water conservancy construction pipeline.

[0034] When the exhaust fan 405 is started, it draws air from the inside of the slag collection box 401. The slag collection box 401 draws in dust generated at the grinding and rust removal location through multiple L-shaped dust suction pipes 402. The drawn-in dust is filtered and collected in the slag collection box 401 by the stainless steel filter cartridge 404. When the cover plate 4 and the slag collection box 401 move left and right for grinding, they also drive the multiple L-shaped dust suction pipes 402 to move left and right as a whole. This makes the L-shaped dust suction pipes 402 move laterally as a whole with the steel wire rust removal brush 403, so that they can accurately follow the movement of the brush and collect dust during grinding and rust removal. This achieves the effect of synchronous and stable suction, filtration and collection of dust generated during grinding and rust removal, reducing the phenomenon of large amounts of dust drifting outward and polluting the on-site environment and harming the health of personnel, and improving the environmental friendliness of the product.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
