The invention discloses a vertical axis wind power generation structure and a wind power generation tower, and relates to the technical field of wind power generation. The vertical axis wind power generation structure comprises a cylindrical fixed sleeve, a rotating sleeve sleeving the outer periphery of the fixed sleeve and rotationally matched with the fixed sleeve, blades arranged on the outerside of the rotating sleeve, a mounting frame arranged on one side of the fixed sleeve, a transmission wheel connected to the mounting frame and in transmission connection with an input shaft of a generator, and a transmission belt connected between the transmission wheel and the rotating sleeve and used for enabling the transmission wheel to rotate under driving by the rotating sleeve. The wind power generation tower comprises a base, and the vertical axis wind power generation structure connected to the base. Power transmission of the vertical axis wind power generation structure adopts thetransmission belt to replace gear transmission, so that the blades and the generator realize flexible transmission connection, and direct transfer of stress of the blades to the generator is prevented. The wind power generation tower adopts the vertical axis wind power generation structure, so that higher height can be achieved, and wind energy in high altitude can be used.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a vertical axis wind power generation structure and a wind power generation tower. Background technique [0002] Most of the existing vertical axis wind turbines use gear transmission between the rotating blades and the generator. When encountering strong winds, the force on the blade is too large and the rotation speed is too fast. Due to the rigidity of the connection between the rotating blade and the gear transmission structure, it is easy to cause slight deformation and misalignment of the transmission shaft and transmission gear, resulting in gears and gears in the gear transmission part. The abnormal wear of the bearing affects the service life of the vertical axis wind turbine. In order to avoid the damage of the vertical-axis wind turbines in strong winds, the existing wind power towers generally have relatively low building heights, making it difficult to...
