Description

Technical Field

[0001] This invention belongs to the field of wind turbine tower technology, specifically relating to a wind turbine tower climbing structure. Background Technology

[0002] Wind turbine towers are the structures that support wind turbines and play a crucial role in the conversion of wind energy into electrical energy. These towers are tall, cylindrical structures, typically made of steel or concrete, and connected together using methods such as bolts and welding.

[0003] The height of wind turbine towers typically ranges from 50 to 140 meters, depending on the type and size of the wind turbines used, as well as factors such as terrain and environmental conditions. Furthermore, to ensure the stability and wind resistance of the wind turbines, the tower design needs to consider various factors, such as the tower's diameter, wall thickness, load-bearing capacity, shape, slope, and weight.

[0004] Currently, most wind turbine towers on the market are manufactured using steel structures. This structure provides good load-bearing capacity and elasticity, while also exhibiting high corrosion resistance and durability, enabling it to adapt to various harsh climates and environmental conditions.

[0005] In existing technologies, most wind turbine towers are located in northern or coastal areas of my country. Northern areas experience strong winds and sandstorms, which easily cause wear and tear on the tower surface. Furthermore, coastal areas have higher humidity and salt content, making the tower surface more susceptible to damage and corrosion. Currently, repairs to the outer side of the tower require manual grinding and re-coating with anti-rust paint using ropes when the wind is calmer. This process is difficult and poses safety hazards, as workers are subject to swaying in the wind. Additionally, wind turbine towers located in offshore areas require immediate painting after grinding and rust removal, necessitating excessive equipment carrying by workers and further complicating the operation. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wind turbine tower climbing and repair structure.

[0007] The technical solution adopted to solve the above-mentioned technical problems is: a wind turbine tower climbing structure, including a main load-bearing structure and a climbing power structure. The main load-bearing structure includes two symmetrically arranged semi-annular support semi-rings. The upper surfaces of the two support semi-rings are provided with semi-annular adjustment grooves. The two support semi-rings are fixedly connected to two symmetrically arranged power slide rails at the bottom wall of the adjustment grooves. Limit grooves are provided on the side of the two symmetrically arranged power slide rails that are close to each other. The two power slide rails are provided with grinding structures and spraying structures. The two support semi-rings form a ring. The inner walls of the two support semi-rings are provided with several evenly distributed elastic clamping structures.

[0008] Through the above technical solution, the supporting semi-ring can be assembled into a supporting body that can support the power support box and the sliding support box. The rod grinder and atomizing spray gun can operate through this supporting body without the need for manual hoisting ropes. The power slide rail limits the power support box and the sliding support box, allowing them to move in a circular motion. The limiting groove can limit the power wheel, preventing the power wheel from derailing and causing the power support box and the sliding support box to move vertically, thus avoiding the safety hazard of the power support box and the sliding support box falling. The elastic clamping structure allows the bullseye pulley to clamp outward as the diameter of the wind turbine tower decreases when the supporting semi-ring rises, preventing the supporting semi-ring from swaying under the action of wind.

[0009] The grinding structure includes a sliding support box, a liquid storage tank is provided on one side of the sliding support box, a sealing cover is provided on the top of the liquid storage tank, and a liquid injection pipe is fixedly connected through one side of the upper surface of the sealing cover. An atomizing spray gun is provided above the sliding support box.

[0010] The above technical solution allows for the clamping and support of the atomizing spray gun via a sliding support box, the storage tank to store the prepared paint, and the injection pipe to serve as a channel for filling the paint. The atomizing spray gun can spray the paint out in a mist at high speed, evenly coating the damaged and sanded areas.

[0011] The spraying structure includes a power support box, a rechargeable battery is installed inside the power support box, a rod grinder is installed above the power support box, a power connection assembly is installed between the power support box and the sliding support box, and the sliding support box and the power support box slide inside the adjustment groove of the support semi-ring.

[0012] Through the above technical solution, the power support box can be powered by a battery, and the rod grinder can grind the damaged parts on the outside of the wind turbine tower.

[0013] Furthermore, a damping support frame is rotatably connected to the center of the upper surface of the sliding support box and the power support box. The damping support frame consists of a rotating shaft and an arc-shaped wrapping plate, and the rotating shaft and the arc-shaped wrapping plate are rotatably connected by a drive motor, which is controlled by a Bluetooth control switch. The arc-shaped wrapping plate of the damping support frame at the sliding support box position is clamped and fixed to the atomizing spray gun, and the arc-shaped wrapping plate of the damping support frame at the power support box position is clamped and fixed to the rod grinder. Fixed support frames are fixedly connected to the outer sides of the two damping support frames, and a visual wireless camera is fixedly connected to the center of the upper surface of each of the two fixed support frames.

[0014] Through the above technical solution, the damping support frame allows for coarse adjustment of the orientation of the atomizing spray gun and the rod grinder, and the damping rotation prevents deviation. The rotating shaft and the arc-shaped wrapping plate are connected by a drive motor, allowing for fine adjustment of the atomizing spray gun and the rod grinder to adjust the direction of grinding and painting. The damage on the outside of the wind turbine tower can be monitored through a visual wireless camera. Grinding of damaged areas is monitored through the visual wireless camera, and painting is monitored at the grinding location through the visual wireless camera, making grinding and painting more precise.

[0015] Furthermore, the power connection assembly includes two quarter-circle arc-shaped connecting rods, with a connecting piece positioned on one side of the two connecting rods close to each other. A second bolt is threaded between the connecting piece and the corresponding connecting rod. The ends of the two connecting rods furthest from the connecting piece are fixedly connected to the side wall of the corresponding sliding support box or power support box.

[0016] The above technical solution allows the sliding support box and the power support box to be connected by connecting rods arranged in a quarter-circle arc, facilitating power transmission and enabling synchronous movement of the sliding support box and the power support box. This reduces the investment in power sources, lowers equipment load and cost. The two connecting rods can be assembled or disassembled using connecting plates and second bolts, making it convenient for carrying, handling and transportation of the equipment.

[0017] Furthermore, two symmetrically arranged sliding protrusions are fixedly connected to the side of the liquid storage tank near the sliding support box, and two symmetrically arranged sliding grooves are opened on the side of the sliding support box near the liquid storage tank. The liquid storage tank and the sliding support box are slidably connected through the sliding protrusions and sliding grooves.

[0018] Through the above technical solution, the sliding protrusion and sliding groove facilitate the assembly and disassembly of the liquid storage tank and the sliding support box, making the overall disassembly unit of the equipment small, which is convenient for overall transportation and handling. At the same time, it is convenient to disassemble the liquid storage tank for cleaning, avoiding paint drying and contamination of the liquid storage tank.

[0019] Furthermore, the climbing power structure includes a first dual-axis motor, which is controlled by a Bluetooth control switch. The driving end of the first dual-axis motor is fixedly connected to a first power shaft. Two symmetrically arranged wire winding reels are fixedly connected to the ends of the two first power shafts away from the first dual-axis motor. Climbing wires are wound and fixedly connected to the wire winding reels. Shaft support frames are rotatably connected to the outer walls of the two first power shafts.

[0020] Through the above technical solution, the first dual-axis motor provides power to the wire winding reel, enabling the wire winding reel to rotate and wind up or unwind the climbing wire. This allows for the raising and lowering of the support half-ring, adjusting the position for grinding and painting. At the same time, the shaft support frame can support the first power shaft, preventing deformation caused by excessive load on the first power shaft.

[0021] Furthermore, a lifting control block is fixedly connected to the middle of the outer wall of the two supporting semi-rings. A through-connecting groove is provided on the upper surface of the two lifting control blocks. An arc-shaped clamping block is provided inside the two through-connecting grooves. A tightening bolt is threaded through the middle of the side wall of the two lifting control blocks. One end of the tightening bolt is rotatably connected to the side wall of the clamping arc block inside the through-connecting groove.

[0022] Through the above technical solution, the lifting control block can fix the support half ring and the climbing steel wire. The climbing steel wire drives the lifting control block and the support half ring to rise and fall, pressing against the arc block to ensure that the climbing steel wire is fully pressed and fixed. Tightening the bolt can adjust the pressing degree of the arc block, thereby fixing or loosening the climbing steel wire.

[0023] Furthermore, the ends of the two climbing steel wires away from the steel wire winding reel pass through the corresponding through-connecting grooves, and the portions of the two climbing steel wires located in the through-connecting grooves are secured by the abutting arc-shaped blocks.

[0024] Furthermore, several of the elastic clamping structures include an elastic cavity disposed on the inner wall of the supporting semi-ring, a bullseye pulley is slidably connected through the elastic cavity, a limit plate is fixedly connected to one end of the bullseye pulley located in the elastic cavity, and a return spring is fixedly connected between the limit plate and the inner wall of the elastic cavity.

[0025] The above technical solution ensures that the bullseye pulley is always pressed against the outer wall of the wind turbine tower by the return spring in the elastic cavity, which can adapt to the situation that the diameter of the wind turbine tower decreases during climbing and avoids the gap between the support half ring and the wind turbine tower, which would cause the support half ring to sway.

[0026] Furthermore, a second dual-axis motor is fixedly connected to one side of the lower surface of the power support box. The second dual-axis motor is controlled by a Bluetooth control switch. A third power shaft is fixedly connected to both drive ends of the second dual-axis motor. A second power shaft is provided on the side of the lower surface of the power support box away from the second dual-axis motor and on both sides of the lower surface of the sliding support box. Power wheels are fixedly connected to both ends of the second power shaft and the end of the third power shaft away from the second dual-axis motor. The power wheels are engaged and rolled in a limiting groove at the corresponding position. Shaft protection frames are rotatably connected to the outer walls of the third power shaft and the second power shaft. The shaft protection frames are fixedly connected to the lower surface of the power support box.

[0027] Through the above technical solution, the second dual-axis motor provides power to the third power shaft, enabling the power wheel to move, thus moving the power support box and adjusting the positions of the power support box and the sliding support box.

[0028] Furthermore, a fixed connecting plate is provided at the position where the lower surfaces of the two supporting semi-rings contact each other, and the two fixed connecting plates are threadedly connected to the corresponding positions of the supporting semi-rings with first bolts.

[0029] Through the above technical solution, the two supporting semi-rings can be fixed together by the first bolt and the fixed connecting plate to form the load-bearing body.

[0030] The beneficial effects of the present invention are as follows: (1) The present invention sets up a climbing power structure and a bearing main structure. The climbing power structure enables the bearing main structure and the bearing equipment on the surface of the bearing main structure to climb automatically, without the need for manual hoisting ropes. This makes the climbing of the outside of the wind turbine tower safer. The ring composed of the supporting half rings is fitted on the outside of the wind turbine tower to avoid the equipment shaking caused by the wind. This makes the spraying and grinding operation of the damaged area more precise. The bullseye pulley makes the sliding friction between the supporting half ring and the wind turbine tower small when the supporting half ring rises. The elastic cavity and the return spring ensure that the bullseye pulley always resists the wind. (1) It is located close to the outside of the wind turbine tower, making it more adaptable; (2) By setting up a power support box and a sliding support box, the power support box provides power to the rod grinder, atomizing spray gun, second dual-axis motor and visual wireless camera through the battery set in the power support box. The rod grinder on the surface of the power support box can grind the damaged position on the outside of the wind turbine tower, and then spray paint through the atomizing spray gun to spray paint the ground position. The prepared paint is stored in the liquid storage tank to provide paint for the atomizing spray gun. The visual wireless camera can locate the damaged position and adjust the grinding and painting position to improve the degree of mechanization and automation. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] This embodiment, designed to facilitate understanding by those skilled in the art, describes the horizontal placement of equipment used for cleaning anchor chains on large ships.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 11 As shown in this embodiment, a wind turbine tower climbing structure includes a load-bearing main body structure and a climbing power structure. The load-bearing main body includes two symmetrically arranged semi-annular support semi-rings 1. A fixed connecting plate 27 is provided at the position where the lower surfaces of the two support semi-rings 1 contact each other. The two fixed connecting plates 27 are threadedly connected to the corresponding positions of the support semi-rings 1 with first bolts 29. The first bolts 29 and the fixed connecting plates 27 can fix the two support semi-rings 1 to each other to form the load-bearing main body. A semi-annular adjustment groove 2 is opened at the position of the upper surface of the two support semi-rings 1. Two symmetrically arranged power slide rails 22 are fixedly connected at the bottom wall position of the two support semi-rings 1 in the adjustment groove 2. A limit groove 30 is opened at the position of the two symmetrically arranged power slide rails 22 that are close to each other. A grinding structure and a spraying structure are provided at the position of the two power slide rails 22. The two support semi-rings 1 form a ring. Several evenly distributed elastic clamping structures are provided at the position of the inner wall of the two support semi-rings 1.

[0047] The supporting semi-ring 1 can be assembled into a supporting body that can support the power support box 19 and the sliding support box 16. The rod grinder 20 and the atomizing spray gun 13 can work through this supporting body without the need for manual hoisting ropes. The power slide rail 22 limits the power support box 19 and the sliding support box 16 to make them move in a circular motion. The limiting groove 30 can limit the power wheel 36 to prevent the power wheel 36 from derailing and causing the power support box 19 and the sliding support box 16 to move vertically, thus avoiding the power support box 19 and the sliding support box 16 from falling and causing safety hazards. Through the elastic clamping structure, when the supporting semi-ring 1 rises, as the diameter of the wind turbine tower decreases, the bullseye pulley 9 clamps outward, preventing the supporting semi-ring 1 from swaying under the action of wind.

[0048] The climbing power structure includes a first dual-axis motor 5, with a first power shaft 7 fixedly connected to the drive end of each of the two first power shafts 5. Two symmetrically arranged wire winding reels 6 are fixedly connected to the ends of the two first power shafts 7 away from the first dual-axis motor 5. Climbing wire 4 is wound and fixedly connected to the wire winding reels 6. A shaft support frame 8 is rotatably connected to the outer wall of the two first power shafts 7. The first dual-axis motor 5 provides power to the wire winding reels 6, causing the wire winding reels 6 to rotate and thus wind or unwind the climbing wire 4. This allows for the raising and lowering of the support half-ring 1, adjusting the position for grinding and painting. At the same time, the shaft support frame 8 can support the first power shafts 7, preventing deformation caused by excessive load on the first power shafts 7.

[0049] The sanding structure includes a sliding support box 16, a liquid storage tank 15 on one side of the sliding support box 16, a sealing cover on the top of the liquid storage tank 15, and a liquid injection pipe 14 that is fixedly connected through one side of the upper surface of the sealing cover. An atomizing spray gun 13 is located above the sliding support box 16. The liquid storage tank 15 can store the prepared paint coating, and the liquid injection pipe 14 can serve as a channel for filling the paint coating. The atomizing spray gun 13 can spray the paint in a mist at high speed, evenly spraying it onto the damaged and sanded area.

[0050] The spraying structure includes a power support box 19, which can be powered by a battery, and a rod grinder 20 can grind the damaged parts on the outside of the wind turbine tower. The rod grinder 20 is located above the power support box 19, and a power connection assembly 3 is provided between the power support box 19 and the sliding support box 16.

[0051] A damping support frame 10 is rotatably connected to the center of the upper surface of the sliding support box 16 and the power support box 19. The damping support frame 10 at the sliding support box 16 is clamped and fixed to the atomizing spray gun 13, and the damping support frame 10 at the power support box 19 is clamped and fixed to the rod grinder 20. Fixed support frames 11 are fixedly connected to the outer sides of the two damping support frames 10. A visual wireless camera 12 is fixedly connected to the center of the upper surface of each of the two fixed support frames 11. The sliding support box 16 can clamp and support the atomizing spray gun 13. The orientation of the atomizing spray gun 13 and the rod grinder 20 can be coarsely adjusted, and the damped rotation prevents deviation. The rotating shaft and the arc-shaped wrapping plate are connected by a drive motor, allowing for fine adjustment of the atomizing spray gun 13 and the rod grinder 20 to adjust the direction of grinding and painting. The damage on the outside of the wind turbine tower can be monitored through the visual wireless camera 12. Damaged parts are ground through the visual wireless camera 12, and the painting is monitored at the grinding position through the visual wireless camera 12, making the grinding and painting more precise.

[0052] like Figure 4 As shown, a second dual-axis motor 32 is fixedly connected to one side of the lower surface of the power support box 19. A third power shaft 35 is fixedly connected to both drive ends of the second dual-axis motor 32. A second power shaft 31 is provided on the side of the lower surface of the power support box 19 away from the second dual-axis motor 32 and on both sides of the lower surface of the sliding support box 16. Power wheels 36 are fixedly connected to both ends of the second power shaft 31 and the end of the third power shaft 35 away from the second dual-axis motor 32. The power wheels 36 are engaged and rolled with the corresponding limiting grooves 30. Shaft guards 33 are rotatably connected to the outer walls of the third power shaft 35 and the second power shaft 31. The shaft guards 33 are fixedly connected to the lower surface of the power support box 19. The second dual-axis motor 32 provides power to the third power shaft 35, so that the power wheels 36 have the power to move, so that the power support box 19 can move and adjust the position of the power support box 19 and the sliding support box 16.

[0053] like Figure 5As shown, lifting control blocks 24 are fixedly connected to the middle of the outer walls of the two supporting semi-rings 1. Through-connecting grooves 25 are formed on the upper surfaces of the two lifting control blocks 24. Arc-shaped clamping blocks 23 are arranged inside the two through-connecting grooves 25. Tightening bolts 26 are threadedly connected to the middle of the side walls of the two lifting control blocks 24. One end of the tightening bolt 26, located inside the through-connecting groove 25, is rotatably connected to the side wall of the clamping block 23. The two climbing steel wires 4 are located away from the steel wire reel 6. The two climbing steel wires 4 are located in the through-connecting groove 25 at the corresponding positions. The portions of the two climbing steel wires 4 located in the through-connecting groove 25 are fixed by the abutting arc block 23. The lifting control block 24 can fix the supporting half ring 1 to the climbing steel wire 4. The climbing steel wire 4 drives the lifting control block 24 and the supporting half ring 1 to rise and fall. The abutting arc block 23 ensures that the climbing steel wire 4 is fully fixed. The tightening bolt 26 can adjust the pressing degree of the abutting arc block 23 to fix or loosen the climbing steel wire 4.

[0054] like Figure 9 As shown, two symmetrically arranged sliding protrusions 17 are fixedly connected to the side of the liquid storage tank 15 near the sliding support box 16. Two symmetrically arranged sliding grooves 18 are opened on the side of the sliding support box 16 near the liquid storage tank 15. The liquid storage tank 15 and the sliding support box 16 are slidably connected by the sliding protrusions 17 and the sliding grooves 18. The sliding protrusions 17 and the sliding grooves 18 facilitate the assembly and disassembly of the liquid storage tank 15 and the sliding support box 16, making the overall disassembly unit of the equipment small, which is convenient for overall transportation and handling. At the same time, it is convenient to disassemble the liquid storage tank 15 for cleaning, avoiding paint drying and contamination of the liquid storage tank 15.

[0055] like Figure 10 As shown, the power connection assembly 3 includes two quarter-circle arc-shaped connecting rods 300. A connecting piece 302 is provided on one side of the two connecting rods 300 that are close to each other. A second bolt 301 is threadedly connected between the connecting piece 302 and the corresponding connecting rod 300. The quarter-circle arc-shaped connecting rods 300 can be connected to each other to connect the sliding support box 16 and the power support box 19, which facilitates power transmission and enables the sliding support box 16 and the power support box 19 to move synchronously. This reduces the investment in power source, reduces equipment load and cost. The connecting piece 302 and the second bolt 301 can be used to assemble or disassemble the two connecting rods 300, which facilitates the carrying, handling and transportation of the equipment.

[0056] like Figure 1 and Figure 12As shown, several elastic clamping structures include an elastic cavity 28 disposed on the inner wall of the supporting semi-ring 1. A bullseye pulley 9 is slidably connected through the elastic cavity 28. One end of the bullseye pulley 9 located in the elastic cavity 28 is fixedly connected to a limiting plate 34. A return spring 21 is fixedly connected between the limiting plate 34 and the inner wall of the elastic cavity 28. The return spring 21 in the elastic cavity 28 ensures that the bullseye pulley 9 is always pressed against the outer wall of the wind turbine tower, adapting to the situation where the diameter of the wind turbine tower decreases during climbing, and avoiding the gap between the supporting semi-ring 1 and the wind turbine tower, which would cause the supporting semi-ring 1 to sway.

[0057] The working principle of this embodiment is as follows: the prepared paint is poured into the storage tank 15 through the injection pipe 14; the two supporting half-rings 1 are merged into a single ring and tightened by the fixing connecting plate 27 and the first bolt 29; then the connecting rod 300 at the position of the sliding support box 16 and the power support box 19 is fixed by the connecting piece 302 and the second bolt 301; the first dual-shaft motor 5 is transported to the top platform of the wind turbine by the lifting motor inside the wind turbine tower and placed there; the shaft support frame 8 is supported on the surface of the top platform of the wind turbine; and the climbing steel wire 4 is lowered and passed through the tunnel. Connect the groove 25, then rotate and tighten the bolt 26 so that the abutting arc block 23 firmly abuts the climbing steel wire 4. Then start the first dual-axis motor 5 so that the climbing steel wire 4 is wound up or released, thereby realizing the lifting and lowering control of the support half ring 1. Then, through the second dual-axis motor 32, the sliding support box 16 and the power support box 19 rotate in the adjustment groove 2. The damage to the outside of the wind turbine tower is detected by the visual wireless camera 12. The damaged area is polished by the rod grinder 20. After polishing, the position of the atomizing spray gun 13 is adjusted to the polishing position, and the paint is sprayed through the atomizing spray gun 13.

[0058] After the damaged area is treated, the first dual-axis motor 5 is used to release the climbing steel wire 4, causing the support half-ring 1 to descend. Then, the second bolt 301 and connecting piece 302 at the connecting rod 300 are removed, and the tightening bolt 26 is loosened so that the pressing arc block 23 no longer presses against the climbing steel wire 4. The climbing steel wire 4 is pulled out and wound into the steel wire winding reel 6. The first dual-axis motor 5 is transported down through the elevator inside the wind turbine tower. Then, the first bolt 29 and the fixed connecting plate 27 at the lower surface of the two support half-rings 1 are removed, and the support half-ring 1 can be removed from the outside of the wind turbine tower. The paint inside the liquid storage tank 15 is then cleaned.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
