Abstract

The invention relates to a power generation device, in particular to a vertical-axis clutch type wind power generation device so as to solve the problems that an existing large-power vertical-axis wind power generator is difficult in self-starting and braking and low in power generation efficiency. The vertical-axis clutch type wind power generation device comprises a wind wheel, a first transmission shaft, a wind wheel locking device, a first coupler, a second transmission shaft, a third coupler, a clutch, a speed increasing gear, a support, a second coupler, a power generator, a tower and two brake devices. The vertically-arranged first transmission shaft is rotationally arranged on the top of the tower, one brake device is arranged on the top of the tower, and the wind wheel locking device is arranged on the top of the part, below a flange plate, of the tower. The upper end of the first transmission shaft is connected with the wind wheel, the lower end of the first transmission shaft is connected with the first coupler, and the speed increasing gear is fixed to the support. The clutch is connected between the second transmission shaft and an input shaft of the speed increasing gear, an output shaft of the speed increasing gear is connected with an input shaft of the power generator through the second coupler, and the other brake device is arranged on a power generator shell. The vertical-axis clutch type wind power generation device is used for wind power generation.

Description

technical field [0001] The invention relates to a power generation device, in particular to a vertical axis wind power generation device with a clutch, and belongs to the technical field of wind power generation equipment. Background technique [0002] Compared with traditional energy sources, wind energy is a sustainable energy that can be recycled, with large reserves, clean and pollution-free; wind power projects have a short construction period, flexible installation scale, and do not occupy a large amount of available land, which has good economic benefits and social benefits. Compared with horizontal axis wind turbines, vertical axis wind turbines have the characteristics of no need to install yaw devices, relatively simple structure and manufacturing process, easy installation, low noise, economical and practical, and adapt to the requirements of giant wind turbines. [0003] There are two types of wind turbines: horizontal axis wind turbines and vertical axis wind t...
