Description

Technical Field

[0001] This invention belongs to the technical field of offshore wind turbine maintenance equipment, and in particular, relates to an anti-collision climbing support device for offshore wind turbine maintenance operations. Background Technology

[0002] Wind power generation is one of the most technologically mature, scalable, and commercially viable power generation methods in the renewable energy sector. Offshore wind turbines are a new type of power generation equipment that utilizes offshore wind resources. Offshore wind turbines require regular maintenance during operation, which necessitates climbing to the top of the turbine. Currently, commonly used climbing equipment includes wind turbine climbing aids, wind turbine climb-free devices, and dedicated wind turbine elevators. Among these, wind turbine climb-free devices occupy less space and are currently the mainstream method for climbing wind turbines.

[0003] However, when the wind turbine is not in operation, workers need to manually climb the climbing frame to the wind turbine nacelle to install and maintain the wind turbine. When workers climb manually, the large range of motion can easily cause them to bump into the climbing frame or the inner wall of the wind turbine, posing a safety hazard. Therefore, a collision-proof climbing frame device for offshore wind turbine maintenance operations has been proposed. Summary of the Invention

[0027] In summary, the anti-collision climbing support equipment for offshore wind turbine maintenance operations operates as follows: First, the operator starts the second servo motor 34, which drives the fourth rotating shaft 32 to rotate. This drives the fifth bevel gear 33 to rotate. The meshing of the fifth bevel gear 33 and the fourth bevel gear 31 drives the fourth bevel gear 31 to rotate, which in turn drives the third rotating shaft 28 to rotate. This drives the second rotating groove 25, which in turn meshes with the second bevel gear 27, causing the second bevel gear 27 to rotate. This drives the second rotating shaft 26 to rotate, which in turn drives the threaded rod 24 to rotate. This causes the fourth sliding rod 21 and the fifth sliding rod 23 to slide within the fourth sliding groove 20 and the fifth sliding groove 22, thereby extending the climbing pole 3. The extension length of the climbing pole 3 can be adjusted according to the needs. Then, the first servo motor 19 is started to drive the first rotating shaft 17 to rotate, which in turn drives multiple first gears 18 to rotate. The meshing of the first gears 18 and the sliding rack 14 causes the multiple sliding racks 14 to slide inside the third sliding groove 15. Then, the sliding rack 14 drives the first sliding block 11 to slide inside the first sliding groove 9. Then, the first sliding block 11 drives the second sliding block 12 to slide inside the second sliding groove 10. Then, the second sliding block 12 drives the inflatable air cushion 13 to extend. The inflatable air cushion 13 is then inflated to protect both sides of the climbing frame. Then, the protective straps 8 are tied to the outside of the body. Then, the protective slider 5 is engaged inside the protective slide rail 4 before climbing.
