[0036] 2. This maintenance and processing device for offshore wind turbine towers and bases is equipped with a lifting motor and a controller, so that the support plate, driven by a screw and a limit rod, moves back and forth in the vertical direction, thereby expanding the contact area between the sprayed cleaning liquid and the wind turbine tower, thereby expanding the cleaning range and further improving the service life of the wind turbine tower;

[0037] 3. This maintenance and processing device for offshore wind turbine towers and bases converts the sliding friction between the limit block and the support frame into rolling friction through the balls arranged on the limit block when the limit block rotates along the circumference of the wind turbine tower, thereby reducing the wear between the limit block and the support frame and extending the service life of the limit block.

[0054] A water tank 2, a water pump 21 and a spray pipe 22 are installed on the wind turbine tower 1. The water tank 2 is mounted on the wind turbine tower 1 and is rotatably connected to the wind turbine tower 1. The water tank 2 is located on the top of the driven wheel 62 and is fixedly connected to the driven wheel 62, so that the rotation of the driven wheel 62 drives the water tank 2 to rotate synchronously. Cleaning liquid is placed in the water tank 2. The water pump 21 is located on the water tank 2 and is fixedly connected to the top of the water tank 2. The spray pipe 22 is a retractable hose. One end of the spray pipe 22 is fixedly connected to the top of the drive plate 44, and the other end of the spray pipe 22 is connected to the water pump 21 through the sealing layer 23, so that the cleaning liquid is not easily spilled from the connection between the spray pipe 22 and the water pump 21. At the same time, the water tank 2 is fixedly connected to the driven wheel 62, so that when the driven wheel 62 rotates, the water tank 2, the water pump 21 and the spray pipe 22 rotate synchronously, so that the spray pipe 22 is not easily entangled on the support plate 24 and the wind turbine tower 1 during rotation, causing safety hazards, thereby improving production safety.

[0055] When the staff needs to clean the wind turbine tower 1 and the base 11, the staff starts the water pump 21. The cleaning liquid in the water tank 2 passes through the water pump 21 and the sealing layer 23, and then passes through the nozzle of the spray pipe 22 on the support plate 24 and is sprayed toward the wind turbine tower 1, thereby cleaning the wind turbine tower 1. In addition, the cleaning liquid passes through the water inlet hole 15 on the support frame 13 and contacts the base 11, thereby cleaning the base 11. At the same time, the staff starts the drive motor 644, and the output shaft of the drive motor 644 rotates to drive the drive wheel 643 to rotate synchronously, and the transmission wheel 642 is meshed with the drive wheel 643, so that the transmission wheel 642 rotates synchronously with the drive wheel 643, and then drives the rotating rod 641 to rotate synchronously, and the rotation of the rotating rod 641 drives the driven wheel 62 to rotate synchronously, and then drives the driving wheel 63 and the water storage tank 2 and the water pump 21 on the driven wheel 62 to rotate synchronously, and the rotation of the driving wheel 63 drives the rotating shaft 61 to rotate synchronously, so that the rotating shaft 61 makes a circular motion around the wind turbine tower 1, thereby driving the limit plate 73 and the support plate 24 to move synchronously, and the rotation of the support plate 24 drives the driving plate 44 and the nozzle of the spray pipe 22 to rotate synchronously, so that the spray pipe 22 cleans the wind turbine tower 1 in the horizontal direction. At the same time, the staff starts the lifting The lowering motor 71 and the driving cylinder 41, the output shaft of the lifting motor rotates to drive the screw 72 to rotate synchronously, and the support plate 24 is lifted and lowered in the vertical direction through the limit plate 73 and the rotating groove 52 on the rotating shaft 61, thereby driving the driving plate 44 and the nozzle of the spray pipe 22 to rise and fall synchronously, expanding the contact area between the cleaning liquid sprayed from the nozzle of the spray pipe 22 and the wind turbine tower 1, and at the same time, the piston rod of the driving cylinder 41 is extended and retracted to drive the driving rod 42 to rise and fall synchronously, thereby driving the driving block 43 to rise and fall synchronously, through the driving block 43 and the driving groove 51, the driving plate 44 rotates to drive the spray pipe 22 to rotate synchronously, further expanding the spraying range of the spray pipe 22, thereby cleaning the wind turbine tower 1, thereby eliminating the need for staff to hold the spray pipe 22 to clean the wind turbine tower 1, reducing the damage caused to the staff by the cleaning fluid, and improving safety. At the same time, after the cleaning liquid cleans the wind turbine tower 1 and the base 11, it is transmitted to the collection box 31 through the transmission pipe 32. After being filtered by the filter plate 12, it is convenient for the staff to recycle the cleaning liquid and save the cleaning liquid.

[0056] The working principle of the present invention is as follows:

[0057] When the maintenance and processing device for offshore wind turbine towers and bases of this embodiment is in use, when the staff cleans the wind turbine tower 1 and the base 11, the staff starts the water pump 21, so that the cleaning liquid in the water storage tank 2, driven by the water pump 21, passes through the sealing layer 23 and the spray pipe 22 in sequence and contacts the wind turbine tower 1, thereby cleaning the wind turbine tower 1. After the cleaning liquid cleans the wind turbine tower 1, it is transmitted to the base 11 after passing through the water inlet hole 15 on the support frame 13 to clean the base 11. Finally, after passing through the transmission hole 14 and the transmission pipe 32 on the support frame 13, the cleaning liquid is transmitted to the collection box 31, and then passes through the filtering action of the filter plate 12 in the collection box 31, which facilitates the filtration of the cleaning liquid, thereby recycling the cleaning liquid.

[0058] At the same time, the staff starts the drive motor 644, and the output shaft of the drive motor 644 rotates to drive the drive wheel 643 to rotate synchronously. The rotation of the drive wheel 643 drives the transmission wheel 642 to rotate synchronously, thereby driving the rotating rod 641 to rotate synchronously. The rotation of the rotating rod 641 drives the driven wheel 62 at the top to rotate synchronously, and then drives the driving wheel 63 to rotate synchronously, so that the driving wheel 63 drives the rotating shaft 61 to make a circular operation around the wind turbine tower 1. The rotation of the driving wheel 63 drives the rotating shaft 61 to rotate synchronously, thereby driving the support plate 24 to rotate synchronously, and then the driving plate 44 on the support plate 24 and the nozzle of the spray pipe 22 rotate synchronously with the water tank 2, so that the cleaning liquid sprayed from the spray pipe 22 is fully in contact with the wind turbine tower 1. The staff starts the lifting motor again, and the output shaft of the lifting motor 71 rotates The screw 72 is driven to rotate synchronously. Driven by the limit plate 73 and the rotating groove 52 on the rotating shaft 61, the support plate 24 is lifted and lowered in the vertical direction, thereby driving the nozzle of the spray pipe 22 to lift and lower in the vertical direction, thereby expanding the cleaning range. In addition, the staff starts the driving cylinder 41, and the piston rod of the driving cylinder 41 is extended and retracted to drive the driving rod 42 to lift and lower synchronously, thereby driving the driving block 43 to move synchronously. Under the action of the driving groove 51 on the driving block 43 and the driving plate 44, the spray pipe 22 and the driving plate 44 rotate in the vertical direction, thereby further expanding the spraying range of the spray pipe 22, so that the staff does not need to hold the spray pipe 22 to clean the wind turbine tower 1 and the base 11, making it difficult for the cleaning fluid to come into contact with the staff, reducing the damage caused by the cleaning fluid to the staff, and improving safety.
