Abstract

The invention discloses a wind turbine generator blade capable of efficiently utilizing wind energy, and relates to the technical field of wind power generation equipment. The wind turbine generator blade comprises fan blades, speed regulating devices, speed reducing devices and a rotating main shaft, wherein the blades are arranged on the rotating main shaft, the multiple fan blades are arranged,the plurality of fan blades are central-symmetrically arranged along the rotating main shaft, when the plurality of fan blades rotate, the rotating axis coincides with the axis of the rotating main shaft, the speed regulating devices are arranged at the tail parts of the fan blades correspondingly, the speed regulating devices can rotate, the speed reducing devices are arranged on one side, closeto the rotating main shaft, of the front parts of the fan blades correspondingly, and the speed reducing devices are vertically arranged with the fan blades correspondingly. The wind turbine generator blade has the beneficial effects that the speed regulating device and the speed reducing device are arranged, and the speed regulating device and the speed reducing device are in cooperation with each other, so that the rotating speed of the wind turbine generator can be effectively controlled, and rotating speed of the wind turbine generator is close to a rated rotating speed, so that the powergeneration rate of the wind turbine generator is improved.

Description

Technical field [0001] The present invention relates to the technical field of wind power generation equipment, in particular to a wind power generator blade that efficiently utilizes wind energy. Background technique [0002] In order to make better use of wind energy, for a long time, people have designed a variety of structural forms of wind turbine devices. According to the different positions of the wind turbine rotation axis in space, they are divided into horizontal wind turbines and vertical wind turbines. Vertical axis wind turbines, traditional horizontal axis generators usually require the yaw operating system to adjust the direction of the wind wheel to capture more wind energy, but the setting of the yaw system increases the total cost of the horizontal axis generator. In addition, the yaw system also Additional energy is needed to realize the operation of the yaw system, and the yaw system accounts for about 50% of the weight of the entire wind turbine, which greatl...
