A magnetic levitation anti-drop-off safety device for a vertical-axis wind power generation system comprises a main pole (1), a lower flange (3), a generator (4), an upper flange (11), a turbine blade lower frame member (12), a turbine blade rotation shaft (13), an anti-drop-off supporting component (2), a middle flange (5), a transmission (6), a magnetic levitation stator component (7), a magnetic levitation rotor component (8), and first and second permanent magnets (9, 10). The anti-drop-off supporting component (2) is fixed at an upper end of the main pole (1). The generator (4) is fixedly installed at the upper end of the main pole (1) and is transmissively connected to the transmission (6). The magnetic levitation stator component (7) is fixedly installed on the anti-drop-off supporting component (2). The magnetic levitation rotor component (8) is fixedly connected to and combined with the upper flange (11) and then transmissively connected to the transmission (6). The turbine blade rotation shaft (13) is fixedly connected to the upper flange (11). The first and second permanent magnets (9, 10) are fixedly installed on the magnetic levitation stator component (7) and the magnetic levitation rotor component (8) respectively. The anti-drop-off safety device has a simple structure and low cost, is convenient to install, and can effectively increase the operation stability of a generator (4), extend the service life of the generator (4) and effectively guarantee that a turbine does not drop off easily in extreme weather conditions such as strong wind.
Description
technical field [0001] The invention relates to auxiliary facilities of a wind power generation system, in particular to a magnetic levitation anti-drop safety device suitable for a vertical axis wind power generation system. Background technique [0002] Vertical axis wind turbines are currently widely used. Common vertical-axis wind turbines usually fix the generator on the upper end of the pole through the connecting flange; the rotor shaft of the wind blade is directly fixed on the top of the generator. The existing problems are as follows: first, the generator The force is large, which affects the operation stability and service life of the generator; second, in extreme weather conditions such as typhoons, the top of the generator is prone to be torn and damaged, and in severe cases, it may even cause the fan to fall and cause injury accidents. big security risk. Contents of the invention [0003] The purpose of the present invention is: aiming at the problems exist...
