Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1-4This utility model provides a technical solution: a rust removal device for wind turbine flanges, comprising a rust removal box 1 and a flange body 2. A door is installed on the front side of the rust removal box 1. A rust removal mechanism is installed inside the rust removal box 1, including a slide rail 301 and a turntable 306. The slide rail 301 is fixed to the inner wall of the rust removal box 1. A sliding plate 302 is slidably mounted on the surface of the slide rail 301. An electric telescopic rod 303 is installed at the bottom of the sliding plate 302. The bottom of the electric telescopic rod 303 is connected to a mounting plate by bolts. A mounting frame 304 is fixedly installed, and a rust-removing roller 305 is installed inside the mounting frame 304. The rust-removing roller 305 is located above the flange body 2. A turntable 306 is rotatably mounted on the inner top wall of the rust-removing box 1. An eccentric shaft 307 is eccentrically fixed to the bottom of the turntable 306. A straight groove 308 is opened on the top of the sliding plate 302, and the eccentric shaft 307 is slidably mounted inside the straight groove 308. A storage box 309 is fixed to the rear side of the rust-removing box 1 by bolts. The storage box 309 contains rust remover. A second through groove is provided on the rear side wall of the rust removal box 1. A connecting pipe 310 is provided between the storage box 309 and the mounting frame 304. The connecting pipe 310 passes through and is sleeved inside the second through groove. The water pump built into the storage box 309 can spray the rust remover from inside the mounting frame 304 through the connecting pipe 310 onto the rust removal roller 305. By setting up a rust removal mechanism, when the turntable 306 rotates, it drives the eccentric shaft 307 to rotate eccentrically, squeezing the inner wall of the straight groove 308. With the limiting action of the rail 301, the slide plate 302 moves back and forth in the horizontal direction. The electric telescopic rod 303 drives the mounting frame 304 and the rust removal roller 305 to move back and forth. At the same time, the rust remover inside the storage box 309 is sprayed onto the surface of the rust removal roller 305 through the water pump and the connecting pipe 310. Since the rust removal roller 305 is in contact with the top of the flange body 2, the rust remover is evenly applied to the surface of the flange body 2. Compared with the prior art, the application effect of the rust remover is better.

[0027] Reference Figures 1-4The rust removal box 1 is equipped with a tilting mechanism, which includes a first connecting rod 401. The first connecting rod 401 is rotatably mounted on the inner wall of the rust removal box 1. A first clamping plate 402 is fixed to the side of the first connecting rod 401 near the flange body 2. A support frame 403 is bolted to the inner wall of the rust removal box 1. A hydraulic rod 404 is mounted on the inner wall of the support frame 403. A second connecting rod 405 is fixed to the output end of the hydraulic rod 404. A second clamping plate 406 is rotatably mounted on the side of the second connecting rod 405 near the flange body 2. The second clamping plate 406 and the second connecting rod 405 are dampedly connected. The first connecting rod 401 and the inner wall of the rust removal box 1 are also dampedly connected. Anti-slip pads are provided on both the holding plate 402 and the second clamping plate 406. By setting a flipping mechanism, the flange body 2 is placed between the first clamping plate 402 and the second clamping plate 406. The hydraulic rod 404 is activated, which drives the second connecting rod 405 and the second clamping plate 406 to move closer to the first clamping plate 402 until the first clamping plate 402 and the second clamping plate 406 clamp the flange body 2. When it is necessary to flip the flange body 2, the electric telescopic rod 303 is activated to move the hanger 304 and the rust removal roller 305 upward, and the first connecting rod 401 is flipped 180 degrees, thereby driving the flange body 2 to flip. There is no need to loosen the flange body 2 and re-clamp it, which improves processing efficiency.

[0028] Reference Figures 1-4The outer wall of the rust removal box 1 is rotatably equipped with a half gear 407 and a first gear 408. The first gear 408 is fixedly connected to the first connecting rod 401. The half gear 407 and the first gear 408 mesh intermittently. A maintenance box 409 is fixedly mounted on the outer wall of the rust removal box 1 by bolts. A motor is fixedly mounted inside the maintenance box 409 by a mounting bracket. The output end of the motor is fixedly connected to the half gear 407. A second gear 410 is rotatably equipped on the outer wall of the rust removal box 1. The half gear 407 and the second gear 410 mesh intermittently. A first bevel gear 411 is coaxially fixed on the side of the second gear 410 away from the side wall of the rust removal box 1. A first transmission rod 412 is rotatably arranged inside the maintenance box 409. A second bevel gear 413 is coaxially fixed on the surface of the first transmission rod 412. The first bevel gear 411 and the second bevel gear 413 mesh with each other. A second transmission rod 414 is rotatably arranged on the top of the rust removal box 1. The bottom of the second transmission rod 414 and the top of the turntable 306 are coaxially fixed. The surfaces of the second transmission rod 414 and the first transmission rod 412 are both... A rotating wheel is fixedly installed. A transmission belt 415 is sleeved on the rotating wheel between the second transmission rod 414 and the first transmission rod 412. By setting a half gear 407, the motor is started, driving the half gear 407 to rotate. When the half gear 407 meshes with the first gear 408, it drives the first gear 408 to rotate, thereby driving the first connecting rod 401 and the flange body 2 to flip. When the meshing teeth of the half gear 407 disengage from the meshing teeth of the first gear 408, the flange body 2 remains stationary with the flipped surface facing upwards. The meshing teeth of the first gear 410 and the second bevel gear 411 mesh, causing the second gear 410 and the first bevel gear 411 to rotate half a turn. Through the meshing connection of the first bevel gear 411 and the second bevel gear 413, the second bevel gear 413 drives the first transmission rod 412 to rotate half a turn. Through the cooperation of the transmission belt 415, the second transmission rod 414 and the turntable 306 rotate half a turn, causing the rust removal roller 305 to move in one direction once. This process is repeated, so that the flange body 2 is flipped and the rust remover is applied alternately.

[0029] Specifically, the working process or working principle of this wind turbine flange rust removal device is as follows: During use, the flange body 2 is placed between the first clamping plate 402 and the second clamping plate 406. The hydraulic rod 404 is activated, driving the second connecting rod 405 and the second clamping plate 406 to move closer to the first clamping plate 402 until the first clamping plate 402 and the second clamping plate 406 clamp the flange body 2. The electric telescopic rod 303 is activated to raise the rust removal roller 305. The motor is started, driving the half gear 407 to rotate. When the half gear 407 meshes with the first gear 408, it drives the first gear 408 to rotate, thereby causing the first connecting rod 401 and the flange body 2 to flip. When the meshing teeth of the half gear 407 and the first gear 408 disengage, the electric telescopic rod 303 is activated to lower the rust removal roller 305. The flange body 2 remains stationary with its flipped surface facing upwards. The meshing teeth of the half gear 407 and the second gear 408... The meshing teeth of the first bevel gear 410 and the second bevel gear 411 rotate half a turn. Through the meshing connection of the first bevel gear 411 and the second bevel gear 413, the second bevel gear 413 drives the first transmission rod 412 to rotate half a turn. Through the cooperation of the transmission belt 415, the second transmission rod 414 and the turntable 306 rotate half a turn. When the turntable 306 rotates, it drives the eccentric shaft 307 to rotate eccentrically, which squeezes the inner wall of the straight groove 308. Under the limiting cooperation of the slide rail 301, the slide plate 302 moves back and forth in the horizontal direction. Through the electric telescopic rod 303, the mounting frame 304 and the rust removal roller 305 move back and forth. At the same time, the rust remover inside the storage box 309 is sprayed onto the surface of the rust removal roller 305 through the water pump and the connecting pipe 310. Since the rust removal roller 305 is in contact with the top of the flange body 2, the rust remover is evenly applied to the surface of the flange body 2. This process is repeated.
