Embodiment
[0025] The wind blade retractable marine generator of this embodiment, as figure 1 , 2 As shown in and 3, it includes a bottom platform 1 and a pylon 2 standing in the center of the platform. The pylon 2 is equipped with a fan blade lifting device 3, and the fan blade lifting device 3 includes a coaxially arranged main shaft 31 and a secondary shaft 32. And the main shaft 31 and the secondary shaft 32 are fixed through socket sockets.
[0026] Three sliders 33 are evenly distributed on the top of the secondary shaft 32, and the three sliders 33 are radially distributed. The hub structure for expanding and contracting the fan blades 34 is also installed inside the sliders 33, and the fan blades 34 pass through the fan blades. The blade rod 35 is fixedly connected with the wheel hub structure; an arc groove 36 is formed on the outer surface of each slider 33, which is convenient for the wheel hub to drive each fan blade rod 35 to expand and contract along the arc groove 36; in ...

The invention relates to a blade-extensible oceanic generator which comprises a bottom platform and a tower column standing in the center of the platform. A blade lifting device is installed in the tower column and comprises a main shaft and an auxiliary shaft which are coaxially arranged. Three sliding blocks are evenly distributed at the top end of the auxiliary shaft in a radial shape. The interiors of the sliding blocks are provided with hub structures used for expanding and retracting blades. The blades are fixedly connected through the hub structures through blade rods. The outer side of each sliding block is provided with an arc groove, and therefore hubs can conveniently drive the blade rods to be expanded and retracted along the grooves. The tower column is provided with sliding grooves used in cooperation with the sliding blocks. The sliding blocks can ascend or descend along the sliding grooves. The blade-extensible oceanic generator has the advantages that the extensible vanes are adopted, and the vanes can be retracted and folded when typhoons, storms and weather mutations occur and can descend to the platform; and after typhoons or storms, the lifting device enables the blades to ascend to the high altitude again, and the blades are unfolded for wind power generation.
Description
technical field [0001] The invention belongs to the technical field of offshore wind power generation, in particular to a wind blade retractable offshore [0002] Ocean generator. Background technique [0003] With the development of economy and society, the demand for energy in production and life is increasing. Wind power generation is the fastest-growing green energy technology in the world. There are few wind farms in areas with variable wind direction and areas with frequent storms. [0004] At present, most of the wind power generators are horizontal-axis wind generators or vertical-axis wind generators. The wind blades are fixed, which is not easy to transport and maintain, and it is easy to cause failures in the event of typhoons and storms. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a marine generator with retractable wind blades, which adopts telescopic wind blades, and when encountering typhoons...
