Description

Technical Field

[0001] This invention belongs to the field of new energy equipment technology, specifically a wind power generation equipment unmanned maintenance device that can automatically climb. Background Technology

[0002] New energy, also known as unconventional energy, refers to various forms of energy other than traditional energy. It refers to energy that has just begun to be developed and utilized or is being actively researched and is yet to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy.

[0003] Wind power generation converts the kinetic energy of wind into electrical energy. As a clean and renewable energy source, wind energy is receiving increasing attention from countries around the world. Its reserves are enormous, with global wind energy estimated at 2.74 × 10^9 MW, of which 2 × 10^7 MW is usable. This is 10 times greater than the total exploitable hydropower on Earth.

[0004] As an important new energy source, wind power is a crucial component in achieving carbon neutrality and carbon peaking. In recent years, with the development of offshore wind power, the installation columns of wind turbines often require additional salt spray corrosion protection. However, long-term operation also necessitates continuous monitoring of the external paint surface of the wind turbine installation columns to prevent paint peeling and cracking, which can lead to rust problems. Existing unmanned maintenance equipment uses traditional ropes and climbing structures, which are not conducive to stable monitoring and imaging. Furthermore, the moving structure is prone to damaging the paint surface of the installation columns. In subsequent use, it was found that the traditional moving structure has poor stability and is prone to shaking and slippage, resulting in poor operational stability. Summary of the Invention

[0005] The technical solution adopted in this invention is as follows: An unmanned maintenance device for wind power generation equipment that can automatically climb, comprising:

[0006] The equipment platform consists of four units.

[0007] A movable assembly is located on the outer wall of the equipment platform. The movable assembly comprises four groups, each group including a fixed assembly, an equipment plate, a drive box, an upper pull-out box, a lower pull-out box, two drive motors, two ball bearing blocks, two lead screws, two constraint rods, and four sleeves. The fixed assembly is located at the center of the outer wall of the equipment plate. Both ends of the equipment plate are fixedly mounted on one side of the outer wall of two adjacent equipment platforms. The drive boxes are fixedly mounted on one side of the outer wall of the equipment plate. The upper and lower pull-out boxes are slidably fitted onto the outer walls of both ends of the drive boxes. The two drive motors are fixedly mounted on the inner walls of the upper and lower pull-out boxes. The two lead screws are fixedly mounted at the output ends of the drive motors. The two ball bearing blocks are fixedly mounted on the inner walls of the upper and lower pull-out boxes. One end of each lead screw is threaded to the inner wall of a ball bearing block. Every two sleeves are fixedly mounted on the inner walls of the upper and lower pull-out boxes. Each constraint rod is slidably embedded in the inner wall of a sleeve.

[0008] Each set of fixing components includes two elastic plates, multiple ball joints, a drive plate, a mounting plate, and a cylinder. The two elastic plates are respectively fixedly installed on both sides of the outer wall of the equipment platform. The multiple ball joints are rotatably embedded in the outer wall of the elastic plates in two groups. The drive plate is slidably embedded in the inner wall of the equipment platform. The mounting plate is fixedly installed at the corner of the outer wall of the drive plate by bolts and nuts. The output end of the cylinder is fixedly installed at the center of one side of the outer wall of the drive plate.

[0009] Furthermore, each of the device platforms has a constraint ring embedded at the top and bottom of its outer wall.

[0010] Furthermore, a base is fixedly installed at the top edge of the outer wall of each device platform, and a monitoring unit is fixedly installed on the top of the outer wall of each base.

[0011] Furthermore, multiple limiting suction cups are installed on one side of the outer wall of the mounting plate.

[0012] Furthermore, multiple negative pressure suction cups are installed on one side of the outer wall of the drive box, the upper pull box, and the lower pull box.

[0013] Furthermore, each of the constraint rods is fixedly installed on the inner wall of the drive box, and both ends of each constraint rod penetrate through to the inner walls of the upper pull box and the lower pull box, respectively.

[0014] Furthermore, each of the equipment platforms is fixedly provided with a mounting base on its inner wall, and one end of the mounting base is fixedly provided on the outer wall of one end of the cylinder.

[0015] Furthermore, a mounting post is provided at the center of the constraint ring, and four equipment slots are provided on the outer wall of the mounting post.

[0016] Furthermore, each of the aforementioned device slots, drive boxes, pull-up boxes, and pull-down boxes is matched with each other.

[0017] Furthermore, one side of the outer wall of the ball joint is attached to the outer wall of the mounting column.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In this invention, the movable component enables stable fixing and movement within the equipment slot, while also allowing movement on an ultra-high mounting column. This ensures efficient movement while preventing equipment swaying due to high-altitude winds, which could lead to the failure of the negative pressure suction cup and the limiting suction cup. Furthermore, combined with the fixing component, the equipment plate can be constrained to the greatest extent possible, preventing swaying during movement that could cause the equipment to fall off.

[0026] 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.

[0027] Example 1

[0028] Reference Figure 1 - Figure 5 A self-climbing, unmanned maintenance device for wind power generation equipment, comprising:

[0029] Equipment station 1, there are four equipment stations in total;

[0030] The moving components are located on the outer wall of the equipment platform 1. There are four sets of moving components, each including a fixed component, an equipment plate 2, a drive box 13, an upper pull box 14, a lower pull box 15, two drive motors 16, two ball bearing blocks 17, two lead screws 18, two constraint rods 19, and four sleeves 20. The fixed component is located at the center of the outer wall of the equipment plate 2. Both ends of the equipment plate 2 are fixedly installed on one side of the outer wall of two adjacent equipment platforms 1. The drive boxes 13 are all fixedly installed on one side of the outer wall of the equipment plate 2. The upper pull box 14 and lower pull box 15... The two drive motors 16 are fixedly mounted on the outer walls of the upper pull box 14 and the lower pull box 15, respectively. The two lead screws 18 are fixedly mounted on the output ends of the drive motors 16. The two ball blocks 17 are fixedly mounted on the inner walls of the upper pull box 14 and the lower pull box 15. One end of each lead screw 18 is threaded to the inner wall of the ball block 17. Every two sleeves 20 are fixedly mounted on the inner walls of the upper pull box 14 and the lower pull box 15. Each constraint rod 19 is closed and slidably embedded in the inner wall of the sleeve 20.

[0031] Each set of fixing components includes two elastic plates 7, multiple ball joints 8, a drive plate 9, a mounting plate 10, and a cylinder 11. The two elastic plates 7 are fixedly installed on both sides of the outer wall of the equipment platform 1. The multiple ball joints 8 are rotatably embedded in the outer wall of the elastic plates 7 in two groups. The drive plate 9 is slidably embedded in the inner wall of the equipment platform 1. The mounting plate 10 is fixedly installed at the corner of the outer wall of the drive plate 9 by bolts and nuts. The output end of the cylinder 11 is fixedly installed at the center of one side of the outer wall of the drive plate 9. Through the moving components, stable fixing and movement can be achieved inside the equipment slot 601. During the movement on the ultra-high mounting column 6, the movement efficiency can be ensured while avoiding equipment shaking caused by high-altitude winds, which could lead to the failure of the negative pressure suction cup 21 and the limiting suction cup. In combination with the fixing components, the equipment plate 2 can be constrained to the greatest extent to prevent shaking during movement and equipment falling off. First, the equipment platform 1 is roughly wrapped around the mounting column 6. On the outer wall of the device, the device plate 2 is installed onto the outer wall of the device platform 1 using bolts. Then, the battery is installed inside each device plate 2. The negative pressure generating structure connects the air path to the input ends of the limiting suction cup 22 and the negative pressure suction cup 21. The relative positions of the mounting plate 10 and the drive plate 9 are adjusted using bolts and nuts to ensure that the limiting suction cup 22 is completely attached to the outer wall of the mounting column 6. After the limiting suction cup 22 completes its adsorption, the drive motor 16 is started, driving the ball block 1 through the lead screw 18. 7 and the upper pull box 14 move upward, and then the negative pressure suction cup 21 is activated to complete the adsorption of the equipment slot 601. At this time, the negative pressure suction cup 21 of the lower pull box 15 is activated to release the adsorption of the limiting suction cup 22. At this time, the drive motor 16 is activated, so that the lead screw 18 drives the drive box 13 and the equipment platform 1 to rise, completing the movement. Then the negative pressure suction cup 21 of the lower pull box is released, and the drive motor 16 is activated to drive the lower pull box 15 to rise. During the movement, the ball joint is attached to the outer wall of the mounting column 6.

[0032] Reference Figure 1 - Figure 5 Each device platform 1 has a constraint ring 3 embedded at the top and bottom of its outer wall. Each device platform 1 has a base 4 fixedly installed at the top edge of its outer wall. Each base 4 has a monitoring body 5 fixedly installed at the top of its outer wall. Multiple limit suction cups 22 are installed on one side of the outer wall of the mounting plate 10. Multiple negative pressure suction cups 21 are installed on one side of the outer wall of the drive box 13, the pull-up box 14, and the pull-down box 15. Each constraint rod 19 is fixedly installed on the inner wall of the drive box 13. The two ends of each constraint rod 19 extend through to the inner walls of the pull-up box 14 and the pull-down box 15, respectively.

[0033] Reference Figure 1 - Figure 5Each equipment platform 1 has a mounting base 12 fixedly installed on its inner wall, and one end of the mounting base 12 is fixedly installed on the outer wall of one end of the cylinder 11. The center of the constraint ring 3 is provided with a mounting column 6, and the outer wall of the mounting column 6 is provided with four equipment slots 601. Each equipment slot 601, drive box 13, upper pull box 14 and lower pull box 15 are matched with each other. One side of the outer wall of the ball joint 8 is attached to the outer wall of the mounting column 6.

[0034] Working principle:

[0035] First, roughly wrap the equipment platform 1 around the outer wall of the mounting column 6. Then, install the equipment plate 2 onto the outer wall of the equipment platform 1 using bolts. Next, install the battery inside each equipment plate 2. The negative pressure generating structure connects the air path to the input ends of the limiting suction cup 22 and the negative pressure suction cup 21. Adjust the relative positions of the mounting plate 10 and the drive plate 9 using bolts and nuts to ensure that the limiting suction cup 22 is completely attached to the outer wall of the mounting column 6. After the limiting suction cup 22 completes its adsorption, start the drive motor 16, which operates via a lead screw... 18 drives the ball block 17 and the upper pull box 14 to move upward. Then the negative pressure suction cup 21 is activated to complete the adsorption of the equipment slot 601. At this time, the negative pressure suction cup 21 of the lower pull box 15 is activated to release the adsorption of the limiting suction cup 22. Then the drive motor 16 is activated, so that the lead screw 18 drives the drive box 13 and the equipment table 1 to rise and complete the movement. Then the negative pressure suction cup 21 of the lower pull box is released, and the drive motor 16 is activated to drive the lower pull box 15 to rise. During the movement, the ball joint is attached to the outer wall of the mounting column 6.
