[0002] The diameter of a wind turbine column is generally 3-9 meters, and its weight can reach tens to hundreds of tons, which is not convenient to replace. During the long-term weathering process, it may lose protection for the entire wind turbine due to external factors, such as flying sand hitting the surface of the generator and causing the anti-corrosion paint to fall off. Therefore, timely repair and maintenance are required.

[0003] The current maintenance method has the following disadvantages:

[0043] like Figure 3-4 As shown, the movable frame 1 is placed outside the column part of the wind turbine, so that the four sets of universal wheels 101 contact the paint surface, and the traveling magnetic block 407 also adheres to the paint surface, and then the device is moved;

[0044] The magnetic seat 105 and the traveling magnetic block 407 are made of appropriate materials, which can be adjusted according to the weight of the device to ensure that the device can be stably adsorbed. It is not necessary to use high-cost materials such as strong magnets, which can save resources and be mass-produced;

[0045] First, the device is raised, and the travel motor 409 is started to drive the two sets of travel synchronous belts 405 to rotate. The travel synchronous belts 405 drive the four sets of travel plates 406 to move in a circular manner.

[0048] Three actions are performed simultaneously in this process:

[0049] The control rack 204 first lifts the lifting member 208, drives the connecting guide rod A207 and the locking block 206 to rise, and pulls the locking block 206 out of the locking ring 302;

Embodiment 3:

[0052] On the basis of Example 1, Figure 8-9As shown, when touch-up is needed, external air is drawn in through the delivery pump 502, passed through the one-way valve 501 and entered into the paint box group 5 for pressurization, so that the paint in the paint box group 5 passes through the delivery pipe 503 and enters the eccentric channel 7, and then is sprayed out from the nozzle on the front side of the nozzle seat 8 for coating. During this period, the paint contacts the impeller to drive the external transmission wheel 701 and the eccentric rod 702 to rotate, and the eccentric rod 702 drives the bar frame 803 and the sliding sweeping brush 802 to move up and down, and the sliding sweeping brush 802 is used to pre-clean the surface of the wind turbine; the entire device is moved to the right by the traveling synchronous belt 405, and the paint is evenly applied by the scraper plate 806, and then the excess paint falls into the collection and recovery bucket 807, and is re-input into the paint box group 5 during the process of air extraction by the delivery pump 502.

[0053] Specific usage and function of this embodiment: In the present invention, when in use, the movable frame seat 1 is placed outside the column part of the wind turbine generator, so that the four sets of universal wheels 101 contact the paint surface, and the traveling magnetic block 407 also adheres to the paint surface, and then the device is moved;

[0055] Then, the first electric cylinder 103 is started to push out the sliding plate 104 and the magnetic seat 105, and the magnetic seat 105 is used to fix the wind turbine. Then, the first motor 203 is started to drive the transverse screw 202 to rotate, and the rack 204 is controlled to move to the left through the threaded transmission. In this process, the lifting member 208 is first lifted up by the control rack 204, driving the connecting guide rod A207 and the card lock block 206 to rise, and the card lock block 206 is pulled out of the card lock ring 302; the connecting rod 205 drives The rotating sleeve 403, the rotating seat 402, the hexagonal rod 401 and the traveling device 4 move backward, and the traveling magnet block 407 temporarily detaches from the wind turbine; at the same time, the rack 204 is controlled to drive the driven gear 301 to rotate, and the transmission rotating sleeve 3 rotates as a whole, driving the hexagonal rod 401 and the traveling device 4 to rotate 90 degrees, and adjusting the angle of the traveling synchronous belt 405. At this time, the traveling synchronous belt 405 provides a left and right movement effect, and then the lifting member 208 is automatically reset when the rack 204 is controlled to move to the leftmost side;

[0056] Start the delivery pump 502 to draw outside air, pass through the one-way valve 501 and enter the paint box group 5 to increase pressure, so that the paint in the paint box group 5 passes through the delivery pipe 503 and enters the eccentric channel 7, and then is sprayed out from the nozzle on the front side of the nozzle seat 8 to coat the paint. During this period, the paint contacts the impeller to drive the external transmission wheel 701 and the eccentric rod 702 to rotate, and the eccentric rod 702 drives the bar frame 803 and the sliding sweeping brush 802 to move up and down, and the sliding sweeping brush 802 is used to pre-clean the surface of the wind turbine generator;

[0057] The entire device is moved to the right by the traveling synchronous belt 405, and the paint is evenly spread by the scraper 806, and then the excess paint falls into the collection and recovery bucket 807, and is re-input into the paint box group 5 during the process of air extraction by the delivery pump 502.
