Description

Technical Field

[0001] The present application relates to the field of civil engineering technology, and in particular to a retractable pedestrian passage between a wind power ship and a wind turbine. Background Art

[0002] As we all know, the ocean occupies more than 70% of the surface of the earth we live on, and all countries attach great importance to the development and utilization of the ocean.

[0003] Against the backdrop of the depletion of fossil energy and severe climate change, wind energy has become a renewable, clean energy with little environmental impact, and its strategic value is increasingly prominent. All countries attach great importance to wind energy. In addition, large-scale offshore power generation is a new market industry, and similar engineering construction experience is very scarce.

[0004] As offshore wind power projects get farther from shore, the sea conditions become more severe. During the construction of wind turbines, there is a certain distance between the ship and the wind turbines. In order to achieve cross-ship supply of equipment, crane lifting, barges and other methods are usually used for transfer, but workers still need cages, rope ladders and other methods to achieve this. Due to the strong winds and waves at sea, the cage or rope ladder may collide or overturn when transferring between the shaking wind turbine hull and the wind turbine, causing workers to fall into the sea and create danger. There is a possibility of safety risk accidents. In order to ensure construction safety, further improvements can be made. Summary of the invention

[0005] In order to ensure the construction safety between the wind turbine ship and the wind turbine during the crossing of the sea and reduce the occurrence of safety risk accidents, the present application provides a retractable pedestrian passage between the wind turbine ship and the wind turbine.

[0039] The second movable ladder 2 includes a second protective bottom plate 21 and a second supporting bottom plate 22. The second supporting bottom plate 22 is fixedly installed on the top of the second protective bottom plate 21 along the length direction of the second protective bottom plate 21. A plurality of second connecting plates 23 are arranged between the two sides of the second protective bottom plate 21 and the two sides of the second supporting bottom plate 22, and are connected and fixed by the second connecting plates 23. Double-buckle sliders 24 protruding outward are arranged on both sides of the second protective bottom plate 21, so that the second protective bottom plate 21 can be slidably arranged in the double-buckle connecting groove 14, thereby realizing the telescopic action between the first movable ladder 1 and the second movable ladder 2.

[0040] The first movable ladder 1 is provided with a transmission mechanism 3 , which is used to drive the telescopic action between the first movable ladder 1 and the second movable ladder 2 . The first movable ladder 1 is provided with a first guardrail 15 , and the second movable ladder 2 is provided with a second guardrail 25 .

[0041] During actual use, the first movable ladder 1 and the second movable ladder 2 provide a relatively stable passage, reducing the risk caused by the shaking of the wind turbine ship hull. The second movable ladder 2 can be slidably set on the first movable ladder 1 through the transmission mechanism 3, so that the length distance between the first movable ladder 1 and the second movable ladder 2 can be adjusted to adapt to the change of the distance between the wind turbine ship and the wind turbine. The first guardrail 15 and the second guardrail 25 can provide additional safety protection for workers when the wind and waves are strong or the wind turbine ship hull shakes, thereby reducing the occurrence of safety accidents.
