Wind turbine

Abstract

The invention discloses a wind turbine. The wind turbine comprises a stand column, wherein a fixing block is fixedly arranged on the upper end face of the stand column; a storage battery is arranged in the fixing block; an annular rotating cavity is arranged on the front side of the storage battery; a gear ring is rotatably arranged in the annular rotating cavity; a meshing gear is in meshing connection with the lower side of the gear ring; a rotating shaft is fixedly arranged at the axis of the meshing gear; the front end of the rotating shaft is rotatably connected with the front end wall ofthe annular rotating cavity; and a first generator is arranged in the end wall of the annular rotating cavity. According to the wind turbine, the angle of rotor blades is adjustable in working, so that the utilization rate of wind energy is maximized; the rotating speed of the rotor blades and a rotating block of the turbine can be reduced by controlling the direction of the rotor blades when thewind turbine is used in severe weather, so that the wind turbine is protected; and under a protection state, the rotating blades arranged in the rotating shaft are able to rotate to generate electricity, so that the electric energy conversion rate of the wind turbine is high.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a wind turbine. Background technique [0002] The length, shape and position of the rotor blades in existing wind turbines are fixed. Due to the uncertainty of the wind flow direction, the fixed blades cannot be adjusted according to the wind direction, so that when the wind passes through the blades, the wind speed is low, and the utilization of wind energy by the device The energy conversion rate is low, resulting in a low energy conversion rate. Secondly, when encountering severe windy weather, the strong wind will cause the rotor blades to rotate at an ultra-high speed, thereby damaging the wind turbine. The device of the present invention can solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a wind turbine to solve the problems raised in the background art above. [0004] In order to achieve the above object, the present in...
