Technical Field
[0001] This utility model relates to the technical field of wind turbine tower cleaning, specifically a wind turbine tower wall cleaning roller brush. Background Technology
[0002] Wind power is such a green and environmentally friendly new energy source. In recent years, wind power has developed rapidly in my country. To operate normally, it requires maintenance and upkeep in various aspects. As it is a rotating machine, it naturally needs grease lubrication. Over time, leaked grease will contaminate the entire tower, not only affecting the appearance of the windmill, but more seriously, the oil stains flowing from top to bottom onto the ground, creating a fire hazard. The windmill tower should be cleaned and decontaminated frequently to eliminate the hazard. Therefore, it is necessary to use a windmill tower wall cleaning roller brush for cleaning.
[0003] Currently, most wind turbine tower cleaning work is carried out manually using suspended baskets and wiping, which is not only labor-intensive and inefficient but also extremely dangerous high-altitude work. To solve these problems, a wind turbine tower exterior cleaning device disclosed in the prior art (application number 202223460520.X, publication date 2022.12.24) can be referenced. This cleaning device uses a mechanically driven roller brush to clean the outer surface of the wind turbine tower. Since the roller brush cover is rotatably connected to the moving platform, under the action of the return spring, the roller brush can adapt to the variable diameter structure of the wind turbine tower's outer wall and always remain in close contact with the outer surface of the wind turbine tower. Combined with the cleaning fluid sprayed from the nozzle, the outer surface of the wind turbine tower is thoroughly cleaned. Compared with traditional manual cleaning methods, this method can improve cleaning efficiency and reduce labor intensity and the risks of high-altitude work.
[0004] Although the above-mentioned device can avoid manual wiping, it still has some shortcomings in actual operation. First, because the outer wall of the wind turbine tower is curved, it can only treat one area during the wiping process and cannot fully wipe other areas on the outside of the wind turbine tower wall.
[0005] Therefore, we proposed that the windmill wall cleaning roller brush can effectively solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a wind turbine tower wall cleaning roller brush to solve the problem mentioned in the background art that the current cleaning devices on the market can only treat a single location during operation and cannot fully wipe other locations on the outside of the wind turbine tower wall.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A windmill casing cleaning roller brush includes a roller brush housing and a support frame fixed to the top of the roller brush housing by bolts. A servo motor for driving force is installed on the side wall of the roller brush housing. The output end of the servo motor extends into the interior of a reduction gear set, and the output end of the reduction gear set is connected to the shaft end of a connecting rod. The connecting rod extends into the interior of the roller brush housing, and its outer end is fixedly connected to a rotating rod. A roller brush body is installed at the outer end of the rotating rod, and an adjustment mechanism is installed at the other end of the roller brush body. The movement of the adjustment mechanism allows the roller brush body to slide on the outside of the rotating rod, achieving cleaning treatment at different positions.
[0009] As a preferred technical solution of this application, a locking block is provided at the outer end of the support connecting frame, and the inner side of the locking block is attached to the connecting end of the crawling robot.
[0010] As a preferred technical solution of this application, the servo motor and the reduction gear set are both fixedly installed on one side of the roller brush housing by a bracket, and the roller brush body is rotatably disposed on the inner side of the roller brush housing.
[0011] As a preferred technical solution of this application, a fixing rod is fixed at one end of the roller brush body near the inner wall of the roller brush shell, and the outer side of the fixing rod slides on the inner side of the mating rod, and the end of the fixing rod that extends into the mating rod is also connected by a return spring.
[0012] As a preferred technical solution of this application, the adjustment mechanism includes a reciprocating screw fixed at one end of a rotating rod, the outer side of the reciprocating screw being threadedly connected to the inner side of the extrusion block, one end of the extrusion block being fixed to one end of a guide rod, and the other end of the guide rod being fixed to the inner wall of the roller brush housing.
[0013] As a preferred technical solution of this application, the moving side of the extrusion block corresponds to the end of the roller brush body, and the roller brush body forms a sliding structure between the extrusion block and the outer side of the rotating rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] The wind turbine tower wall cleaning roller brush is equipped with an adjustment mechanism. By adjusting the mechanism, the roller brush body can be moved inside the roller brush shell, thereby enabling the roller brush body to act on different positions on the outer wall of the wind turbine tower, and thus achieving cleaning treatment for different positions.
[0016] Specifically:
[0017] 1. A servo motor is installed. The output of the servo motor, through a reduction gear set, can not only drive the connecting rod to rotate, thus increasing the speed of the roller brush body and improving efficiency, but also drive the adjustment mechanism to operate. The rotation of the reciprocating screw can drive the extrusion block to extrude one side of the roller brush body through the guide rod, thereby realizing the sliding of the roller brush body on the outside of the rotating rod, which can perform cleaning treatment on different positions.
[0018] 2. A support connecting frame is set up. One side of the support connecting frame is fixed to the top of the roller brush shell, and the other end of the support connecting frame is fixed to the connecting end of the crawling robot by a locking block. This allows the crawling robot to drive the roller brush shell to clean the outer wall of the wind turbine tower. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-7 The present invention provides the following technical solution:
[0029] Example 1
[0030] To address the issue that current cleaning devices on the market can only treat one area during operation due to the curved shape of the wind turbine tower's outer wall, thus failing to adequately clean other areas of the tower's exterior, please refer to the attached document. Figure 1 - Appendix Figure 6 A roller brush body 8 is provided at the outer end of the rotating rod 7, and an adjustment mechanism is provided at the other end of the roller brush body 8. The movement of the adjustment mechanism enables the roller brush body 8 to slide on the outside of the rotating rod 7 to achieve cleaning treatment at different positions. The adjustment mechanism includes a reciprocating screw 9 fixed at one end of the rotating rod 7. The outer side of the reciprocating screw 9 is threaded to the inner side of the extrusion block 10. One end of the extrusion block 10 is fixed to one end of the guide rod 11, and the other end of the guide rod 11 is fixed to the inner wall of the roller brush shell 1. The side of the extrusion block 10 that moves corresponds to the end of the roller brush body 8, and the roller brush body 8 forms a sliding structure between the extrusion block 10 and the outer side of the rotating rod 7.
[0031] First, when cleaning the outer wall of the wind turbine tower, the outer side of the roller brush body 8 is aligned with the outer wall of the wind turbine tower. Then, the roller brush housing 1 moves, allowing the roller brush body 8 to clean the outer wall of the wind turbine tower. To expand the cleaning range, the servo motor 4 is activated. The output end of the servo motor 4 drives the connecting rod 6 to rotate on the outer wall of the roller brush housing 1 through the reduction gear set 5. This causes the connecting rod 6 to drive the rotating rod 7 and the roller brush body 8 to rotate. At this time, the roller brush body 8 will also rotate faster, improving the cleaning efficiency of the outer wall of the wind turbine tower. When the rotating rod 7 rotates, it will also drive the reciprocating screw 9 to rotate, causing the pressing block 10 threaded to the outer side of the reciprocating screw 9 to move. This causes the pressing block 10 to move through the guide rod 11, thus pressing one side of the roller brush body 8. This causes the roller brush body 8 to slide inside the mating rod 13 through the fixing rod 12, thereby adjusting the position of the roller brush body 8 outside the rotating rod 7, thus expanding the cleaning range of the outer wall of the wind turbine tower.
[0032] Example 2
[0033] For easier cleaning of the wind turbine tower's outer wall, please refer to the attached document. Figure 1 Appendix Figure 2 and attached Figure 7The system includes a roller brush housing 1 and a support frame 2 fixed to the top of the roller brush housing 1 by bolts. A servo motor 4 is installed on the side wall of the roller brush housing 1 as a driving force. The output end of the servo motor 4 extends into the interior of a reduction gear set 5, and the output end of the reduction gear set 5 is connected to the shaft end of a connecting rod 6. The connecting rod 6 extends into the interior of the roller brush housing 1, and its outer end is fixed to the rotating rod 7. A locking block 3 is installed at the outer end of the support frame 2, and the inner side of the locking block 3 is attached to the connecting end of the crawling robot. The servo motor 4 and the reduction gear set 5 are both fixedly installed on one side of the roller brush housing 1 by brackets. The roller brush body 8 is rotatably installed on the inner side of the roller brush housing 1. A fixing rod 12 is fixed at one end of the roller brush body 8 near the inner wall of the roller brush housing 1, and the outer side of the fixing rod 12 slides on the inner side of the mating rod 13. The end of the fixing rod 12 that extends into the mating rod 13 is also connected by a return spring 14.
[0034] By setting up the support connecting frame 2 and the locking block 3, one side of the roller brush shell 1 can be fixed to the connecting end of the crawling robot. At this time, by the rolling of the crawling robot, the crawling robot can drive the roller brush shell 1 to crawl on the outer wall of the wind turbine tower, so that the roller brush body 8 inside the roller brush shell 1 can clean the outer wall of the wind turbine tower, which can effectively avoid oil residue on the outer wall of the wind turbine tower.
