Abstract: The present disclosure provides a wind power generation apparatus, including a fan configured to obtain wind energy; a first generator, connected with the fan and a load and configured to convert the wind energy obtained by the fan into first electric energy and output the first electric energy to the load; a gas storage module, connected between the first generator and the load and configured to store or release gas; where when an output power of the first generator is greater than a load power of the load, the first generator drives the gas storage module to store a gas; and when the output power of the first generator is lower than the load power, the gas storage module releases a stored gas to generate second electric energy and output the second electric energy to the load.

Abstract: The present application discloses a boarding apparatus for an offshore platform, including a lifting apparatus and a track structure; the track structure is connected to a platform main body of the offshore platform and extends beyond the platform main body; the lifting apparatus is connected to the track structure, and the lifting apparatus is at least movable along the track structure with a moored sea transporting apparatus; the lifting apparatus includes a ride-on assembly for lifting transportation of a ride-on object between the track structure and the sea transporting apparatus. This thus overcomes the impossibility of boarding caused by marine environmental factors and improves boarding efficiency, and avoids damage caused by the collision between the sea transporting apparatus and the offshore platform when the sea transporting apparatus is berthed at the platform.

Abstract: The present application provides a vertical axis wind turbine and a floating body. The vertical axis wind turbine includes a tower, a main shaft, a supporting rod and a blade; where the main shaft is connected with the tower, and the main shaft is provided to be rotatable around a central axis of the tower; the blade is connected to the main shaft by the supporting rod; the tower is retractable. In the present application, the tower and the blade of the vertical axis wind turbine can be contracted, or the tower and the blade can be put down after contraction, or the tower and the blade can be contracted and then stored below a deck, thus reducing the space occupied by the vertical axis wind turbine on the deck of the floating body to meet different operation requirements of the floating body.
