The invention relates to wind power generation, in particular to a vertical axis wind power generating device which comprises a bracket, a generator and an impeller, wherein the impeller comprises blades, a wheel spoke, a wheel hub and a spindle; the blades are connected to the wheel spoke, and the wheel spoke is connected to the wheel hub; and the wheel hub can rotate around the spindle. The device is characterized in that the impeller is in an H shape and vertically arranged; the generator is connected with the spindle; and the spindle is a vertical shaft and provided with an automatic yawing braking and speed regulating device. The device has the advantages of simple structure, low manufacture cost, high service efficiency, good safety, convenient operation and maintenance, low noise, and the like. Meanwhile, the functions that a fan is started with a large moment at low wind speed and efficiently run at high wind speed and high rotating speed, and braking is automatically carried out to regulate the speed at superhigh wind speed so as to protect the fan can be realized.
Description
Technical field: [0001] The patent of the present invention relates to wind power generation, especially a vertical axis wind power generation device with low starting wind speed and high power generation efficiency. Background technique: [0002] As we all know, a wind turbine is an energy conversion device that converts wind energy into mechanical energy, electrical energy or thermal energy. It can be divided into horizontal axis wind turbines and vertical axis wind turbines according to the position of the wind rotor shaft. Gear box, generator) in the horizontal direction is called a horizontal axis wind turbine (Horizontal Axis Wind Turbine, HAWT). The energy drive chain in the vertical direction is called a vertical axis wind turbine (Verticaol Axis Wind Turbine, VAWT). [0003] The horizontal axis wind turbine is the most developed and most common wind turbine at home and abroad, and it is also the most mature technology. The starting moment of the wheel is relativel...
