Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower cleaning, in particular to a wind power tower cleaning device. Background Art

[0002] Wind turbine towers, as the most fundamental component of wind turbines, support the normal operation of the core generator sets and rotating blades. Since wind turbines are often located on mountain ridges or mountaintops, prolonged operation inevitably results in numerous stains adhering to the outer walls of the wind turbine towers. Prolonged periods of lack of cleaning and maintenance can erode the paint film on the towers, and in severe cases, lead to rust. Furthermore, to increase economic benefits, some wind farms are now designated as new energy tourist attractions. These situations all require regular cleaning of wind turbine towers.

[0003] Existing wind turbine towers are still mostly cleaned manually. This is because manual cleaning is a high-altitude operation, which is dangerous and expensive. Furthermore, workers must work in low wind speeds, which reduces efficiency. Furthermore, wind turbine towers are often dozens of meters high, requiring a large workload and causing fatigue for workers during long hours. Summary of the Invention

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0021] like Figure 1-Figure 3 As shown, a wind turbine tower cleaning device provided in this embodiment includes a frame 1, a fixed component 2 is provided in the frame 1, a conveying component 3 is provided in the fixed component 2, the conveying component 3 includes a conveying pipe 301 located in the fixed component 2, the conveying pipe 301 is used to convey cleaning liquid, and a plurality of groups of nozzles 302 are equidistantly installed in the conveying pipe 301, the cleaning liquid is sprayed toward the tower through the nozzles 302, an external pipe 303 is installed on one side of the bottom end of the conveying pipe 301, the external pipe 303 can be connected to an external liquid supply pipeline, and a cleaning component 4 is provided at the top of the frame 1, the cleaning component 4 includes a fixed seat 401 installed separately at the top of the frame 1, the fixed seat 401 can fix the connecting seat 402, the connecting seat 402 is installed in the fixed seat 401, the cleaning brush 403 is installed in the fixed seat 401 through the connecting seat 402, and a cleaning brush 403 is installed on one side of the connecting seat 402, and the cleaning brush 403 can clean the surface of the tower.

[0022] like Figure 1-Figure 2 As shown, the rack 1 includes a first casing 101 and a second casing 102, and the first casing 101 and the second casing 102 are connected by bolts, so that the first casing 101 and the second casing 102 are placed on both sides of the tower respectively, and form a circular structure after being connected.

[0023] like Figure 2-Figure 3 As shown, the fixing assembly 2 includes a first fixing frame 201 and a second fixing frame 202. The first fixing frame 201 is installed in the first housing 101, and the second fixing frame 202 is installed in the second housing 102, which facilitates the installation of the first fixing frame 201 and the second fixing frame 202 in the first housing 101 and the second housing 102.

[0024] like Figure 2-Figure 3 As shown, the delivery pipe 301 is fixedly connected to the first fixing frame 201 , and the delivery pipe 301 is snap-connected to the second housing 102 , so that the delivery pipe 301 can be conveniently fixed by the first fixing frame 201 and the second fixing frame 202 .

[0025] like Figure 1-Figure 2 As shown, a limiting assembly 5 is installed at the opposite ends of the first housing 101 and the second housing 102. The limiting assembly 5 includes a main rod 501, a compression spring 502, a movable rod 503 and a ball 504, which can limit the cleaning device through the limiting assembly 5 during the lifting process.

[0026] like Figure 1-Figure 2As shown, the movable rod 503 is slidingly connected to the main rod 501 through the compression spring 502, and the ball 504 is rollingly connected to the movable rod 503. Since the diameter of the tower gradually decreases from bottom to top, during the operation of the limit assembly 5, the movable rod 503 contacts the tower through the ball 504. When the diameter is reduced, the reaction force of the compression spring 502 causes the movable rod 503 to move along the main rod 501, and then the ball 504 is tightly against the tower, ensuring the stability of the device during movement.

[0027] like Figure 1-Figure 2 As shown, the lifting ring 6 is respectively connected to the first housing 101 and the second housing 102 by threads, which facilitates fixing the lifting ring 6 on the first housing 101 and the second housing 102, thereby allowing the external lifting equipment to drive the rack 1 to move up and down.

[0028] Working principle of this device: When this device is used, the lifting ring 6 is fixed on the first housing 101 and the second housing 102, and the first housing 101 and the second housing 102 are placed on both sides of the tower respectively, and the first housing 101 and the second housing 102 are assembled. During assembly, the delivery pipe 301 will enter the second fixing frame 202 in the second housing 102, and one side of the delivery pipe 301 will be fixed by the second fixing frame 202. After the fixing is completed, the first housing 101 and the second housing 102 are connected with bolts to form a ring, and then the external lifting equipment drives the frame 1 to move along the tower through the lifting ring 6, and the cleaning brush 403 in the cleaning component 4 is cleaned during the movement. When in contact with the tower, the stubborn stains are cleaned first, and the external pipe 303 in the conveying component 3 is connected to the external liquid supply equipment. The cleaning liquid is sprayed to the surface of the tower by the nozzle 302 through the conveying pipe 301, thereby cleaning the surface of the tower without manual cleaning, which not only reduces the risk but also improves efficiency. At the same time, the cleaning device is limited by the limit component 5 during the lifting process. During the operation of the limit component 5, the movable rod 503 contacts the tower through the ball 504. When the diameter of the cylinder is reduced, the reaction force of the compression spring 502 causes the movable rod 503 to move along the main rod 501, and then the ball 504 is tightly against the tower, ensuring the stability of the device during movement.

[0029] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
