Cleaning device for wind turbine tower

Abstract

This invention relates to the field of wind turbine tower cleaning technology, specifically to a cleaning device for wind turbine towers, including a mounting block. Two sets of mounting columns are mounted on the lower end of the mounting block via a sliding assembly. A first housing is mounted on the outer side of the two sets of mounting columns, and a wiping assembly is mounted in the middle of the first housing. This invention, by setting up the wiping assembly and the sliding assembly, uses power provided by a motor to drive a winding reel to rotate, thereby causing the reel to wind and unwind the cable. This allows a first slider to slide up and down in a third sliding groove, thereby causing sponge blocks to wipe the surface of the wind turbine tower. When the first slider slides, a first roller rolls, and through a series of transmissions, a second roller rolls, thereby driving the second housing to rotate, causing multiple sets of sponge blocks to rotate. Simultaneously, the third roller rolls in the mounting groove, causing the sponge blocks to rotate, thus achieving a better wiping effect and eliminating the need for manual wiping of the wind turbine tower, making wind turbine tower cleaning more convenient.

Description

Technical Field

[0001] This invention relates to the field of wind turbine tower cleaning technology, and more specifically, to a cleaning device for wind turbine towers. Background Technology

[0002] Wind energy refers to the kinetic energy generated by the movement of large amounts of air across the Earth's surface. Due to variations in temperature and water vapor content in different parts of the Earth's surface caused by solar radiation, air pressure differences arise. This causes high-pressure air to flow horizontally towards low-pressure areas, creating wind. Wind energy resources are determined by wind energy density and the annual cumulative number of usable wind energy hours. Wind energy density is the power of wind available per unit windward area, and it is directly proportional to the cube of the wind speed and the air density. Wind turbine towers are the supports used in wind turbine generators, primarily providing structural support and absorbing vibrations from the generator.

[0003] Currently, wind turbine towers require cleaning and maintenance during daily use. This usually requires workers to climb to a high altitude and manually clean the towers. This method is very unsafe, as workers need to be extremely careful during the cleaning process. Moreover, at high altitudes, workers have limited mobility, making the cleaning of wind turbine towers slow. Summary of the Invention

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention, by setting up a wiping component and a sliding component, uses the power provided by the motor to drive the winding wheel to rotate, thereby causing the winding wheel to wind up and down the cable. This allows the first slider to slide up and down in the third sliding groove, thereby causing the sponge blocks to wipe the surface of the wind turbine tower. When the first slider slides, the first roller rolls, and through a series of transmissions, the second roller rolls, thereby driving the second housing to rotate, causing multiple sets of sponge blocks to rotate. At the same time, the third roller rolls in the mounting groove, causing the sponge blocks to rotate, thereby achieving a better wiping effect and eliminating the need for manual wiping of the wind turbine tower, making the cleaning of the wind turbine tower more convenient.

[0018] 2. This invention incorporates a water storage component. During the wiping process of the sponge block, rainwater collected daily by the third housing is used. As the first slider slides, the first roller rotates, driving the first bevel gear to rotate. The first bevel gear drives the third bevel gear, which in turn drives the third rotating shaft. The second transmission belt transmits the power of the third disc to the second disc, causing the second rotating shaft to rotate the partition. When the partition rotates, rainwater flows from the third housing through the fourth housing into the pipe, eventually wetting the sponge block through the water inlet. This improves the wiping effect of the sponge block. Simultaneously, the partition allows for intermittent replenishment of water to the sponge block, preventing waste. When the third housing collects rainwater, the rainwater accumulates at the top of the cover, causing the cover to open. After the rainwater flows down from the top of the cover, the spring returns, closing the cover and preventing the rainwater in the third housing from evaporating. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the present invention provides a cleaning device for wind turbine towers, including a mounting block 1.

A first roller 417 is rotatably connected to the middle of the first slider 416 on the left side. A toothed groove 418 is formed in the middle of the first roller 417. A first gear 419 is rotatably connected to the middle of the second mounting plate 415 on the left side near the mounting block 1. The first gear 419 and the toothed groove 418 mesh with each other. A first bevel gear 420 is fixedly connected to both the front and rear ends of the first gear 419. A second bevel gear 421 is rotatably connected to the rear side of the second mounting plate 415 on the left side. The bevel gear 421 and the rear first bevel gear 420 mesh with each other. The lower end of the second bevel gear 421 is fixedly connected to the first disk 422. The end of the left second mounting plate 415 away from the mounting block 1 is rotatably connected to the second roller 423. The lower end of the second roller 423 and the outer side of the first disk 422 are fitted with the same first transmission belt 424. The ends of the two sets of second mounting plates 415 away from the mounting block 1 are slidably connected to the inner side of the second housing 411. The inner side of the second housing 411 is provided with a second sliding groove 430 that cooperates with the second mounting plate 415. The second roller 423 is in contact with the inner wall of the second sliding groove 430.

[0034] The first rotating shaft 412 is fixedly connected to a third roller 425 at the end away from the mounting block 1, and the lower end of the first housing 3 is provided with a mounting groove 426.

[0035] A rod 427 is inserted into the middle of the first mounting plate 413. A slot 428 that cooperates with the rod 427 is opened in the middle of the first mounting plate 413. A compression spring 429 is fixedly connected to the end of the rod 427 away from the mounting block 1.

[0036] The sliding assembly includes a third slide groove 511, and two sets of first sliders 416 are slidably connected to the outside of two sets of mounting posts 2 respectively. The outside of the mounting posts 2 is provided with a third slide groove 511 that cooperates with the first sliders 416.

[0037] A third mounting plate 512 is fixedly connected to both the left and right sides of the upper end of mounting block 1. A winding reel 513 is rotatably connected to the middle of the third mounting plate 512. A second gear 514 is fixedly connected to the rear end of the winding reel 513. The two sets of second gears 514 mesh with each other. A motor 515 is fixedly mounted on the left side of the upper end of mounting block 1. The output shaft of the motor 515 is fixedly connected to the front end of the left winding reel 513. Cables 516 are wound around the middle of both sets of winding reels 513. The lower ends of the two sets of cables 516 are fixedly connected to the upper ends of the two sets of second mounting plates 415 respectively. Before using the device, the mounting block 1 is welded to the upper end of the wind turbine tower, and the mounting column 2 is welded to both sides of the wind turbine tower. Start. The motor 515 provides power to drive the left winding reel 513 to rotate. The left winding reel 513 drives the left second gear 514 to rotate, which in turn drives the right second gear 514 to rotate. This causes both sets of winding reels 513 to rotate simultaneously, releasing the cable 516 at the same time. This causes the second mounting plate 415 to move downwards, and the first slider 416 to slide in the third groove 511. Simultaneously, the first slider 416 drives the first roller 417 to roll on the inner wall of the third groove 511, driving the first gear 419 to rotate through the toothed groove 418. The first bevel gear 420 rotates, which in turn drives the second bevel gear 421 to rotate. The second bevel gear 421 then drives the first disc 422 to rotate. The power of the second bevel gear 421 is transmitted to the second roller 423 via the first transmission belt 424, causing the second roller 423 to rotate. The second roller 423 then drives the second housing 411 to rotate within the first housing 3. The second housing 411 drives the first rotating shaft 412 to rotate, which in turn drives the first mounting plate 413 to rotate. The first mounting plate 413 then drives the insertion rod 427 to rotate, which in turn drives the sponge block 414 to rotate. Simultaneously, the second housing 411... 11 drives the third roller 425 to rotate, causing the third roller 425 to roll in the mounting groove 426, thereby causing the third roller 425 to drive the first mounting plate 413 to rotate, which in turn causes the sponge block 414 to rotate, thus improving the wiping effect of the sponge block 414 and making the wind turbine tower cleaner. During the process of the sponge block 414 wiping the wind turbine tower, as the first slider 416 slides in the third sliding groove 511, the diameter of the wind turbine tower continuously changes. Through the elastic force provided by the compression spring 429, the insertion rod 427 extends outward from the slot 428, so that the insertion rod 427 always drives the sponge block 414 to press against the outside of the wind turbine tower.

[0038] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the water storage assembly includes a connecting block 611. The end of the third roller 425 away from the mounting block 1 is rotatably connected to the connecting block 611. A pipe 612 is fixedly connected to the outside of the connecting block 611. Water passage holes 613 are opened in the middle of the third roller 425 and the insertion rod 427. A water tank 614 is opened at the upper end of the second housing 411. The upper end of the first housing 3 is fixedly connected to the third housing 615.

[0039] The lower left end of the third housing 615 is fixedly connected to the fourth housing 616, the middle of the fourth housing 616 is rotatably connected to the second shaft 617, and the outer side of the second shaft 617 is fixedly connected to two sets of partitions 618.

[0040] The second shaft 617 is fixedly connected to the second disc 619 at one end near the mounting block 1. The front side of the second mounting plate 415 on the left side is rotatably connected to the third shaft 620. The right end of the third shaft 620 is fixedly connected to the third bevel gear 622. The third bevel gear 622 and the front first bevel gear 420 mesh with each other. The left end of the third shaft 620 is fixedly connected to the third disc 621. The third disc 621 and the second disc 619 are fitted with the same second transmission belt 623.

[0041] The upper end of the third housing 615 is rotatably connected to four sides of a cover plate 624. A spring plate 625 is fixedly connected to the lower end of each cover plate 624. When the sponge block 414 wipes the wind turbine tower, as the first slider 416 slides, the first bevel gear 420 drives the third bevel gear 622 to rotate. The third bevel gear 622 drives the third rotating shaft 620 to rotate, which in turn drives the third disc 621 to rotate. The second transmission belt 623 transmits the power of the third disc 621 to the second disc 619, causing the second disc 619 to drive the second rotating shaft 617 to rotate. The second rotating shaft 617 then drives the partition plate 618 to rotate, allowing water to flow out from the upper end of the fourth housing 616. The water flows along... The water flows from the fourth housing 616 into the pipe 612, and from the pipe 612 into the water inlet 613. Finally, the water inlet 613 wets the sponge block 414, thus making the sponge block 414 more effective at wiping the wind turbine tower. During daily use, the device collects rainwater through the third housing 615. On sunny days, the cover 624 is closed to prevent the water in the third housing 615 from evaporating. On rainy days, as rainwater drips onto the top of the cover 624, the gravity of the rainwater presses the cover 624 down, causing the cover 624 to open. The spring plate 625 compresses the rainwater and allows it to flow into the third housing 615. When the rain stops, the water accumulated on the top of the cover 624 has drained away, and the spring plate 625 rebounds, causing the cover 624 to close.

[0042] Working principle of this invention:

[0043] Before using the device, the mounting block 1 is welded to the upper end of the wind turbine tower, and the mounting column 2 is welded to both sides of the wind turbine tower. The motor 515 is started, and the power provided by the motor 515 drives the left winding reel 513 to rotate. The left winding reel 513 drives the left second gear 514 to rotate, which in turn drives the right second gear 514 to rotate, causing both sets of winding reels 513 to rotate simultaneously. This causes both sets of winding reels 513 to release the cable 516 simultaneously, resulting in the second mounting plate 415 moving downwards. The first slider 416 slides in the third groove 511, and simultaneously, the first slider 416 drives the first roller 417, causing the first roller 417 to roll on the inner wall of the third groove 511. This first roller 417 drives the first gear 419 to rotate through the toothed groove 418, and the first gear 419 drives the first bevel gear 420 to rotate. The first bevel gear 420 drives the second bevel gear 421 to rotate, and the second bevel gear 421 drives the first disc 422 to rotate. The power of the second bevel gear 421 is transmitted to the second roller 423 through the first transmission belt 424, causing the second roller 423 to rotate. The second roller 423 drives the second housing 411 to rotate within the first housing 3. The second housing 411 drives the first rotating shaft 412 to rotate, and the first rotating shaft 412 drives the first mounting plate 413 to rotate. The first mounting plate 413 drives the insertion rod 427 to rotate, and the insertion rod 427 drives the sponge block 414 to rotate. At the same time, the second housing 411 drives the third roller 425 to rotate, causing the third roller 425 to roll in the mounting groove 426. This causes the third roller 425 to drive the first mounting plate 413 to rotate, which in turn causes the sponge block 414 to rotate.

[0044] At the same time, the first bevel gear 420 drives the third bevel gear 622 to rotate, the third bevel gear 622 drives the third rotating shaft 620 to rotate, the third rotating shaft 620 drives the third disc 621 to rotate, and the power of the third disc 621 is transmitted to the second disc 619 through the second transmission belt 623, so that the second disc 619 drives the second rotating shaft 617 to rotate, and the second rotating shaft 617 drives the partition 618 to rotate, so that the water at the top of the fourth housing 616 can flow out. The water flows along the fourth housing 616 into the pipe 612, and from the pipe 612 into the water passage hole 613. Finally, the sponge block 414 is wetted through the water passage hole 613 and the wind turbine tower is wiped.

[0045] During the process of the sponge block 414 wiping the wind turbine tower, as the first slider 416 slides in the third slide groove 511, the diameter of the wind turbine tower changes continuously. The elastic force provided by the compression spring 429 causes the insertion rod 427 to extend outward from the slot 428, so that the insertion rod 427 always drives the sponge block 414 to press against the outside of the wind turbine tower.

[0046] During daily use, the device collects rainwater through the third housing 615. On sunny days, the cover 624 is closed to prevent moisture from evaporating from the third housing 615. On rainy days, as rainwater drips onto the top of the cover 624, the weight of the rainwater presses the cover 624 down, causing it to open. The spring plate 625 compresses the rainwater, allowing it to flow into the third housing 615. When the rain stops, the water accumulated on the top of the cover 624 has drained away, and the spring plate 625 rebounds, causing the cover 624 to close.
