Abstract

The invention relates to a wind energy multiplex device, which comprises a case, a blade, a turntable, a main shaft and a generator shaft, wherein the left end of a sheath is rotationally provided with the turntable, the blade is rotationally arranged on the turntable, the turntable is provided with a sleeve hollowly sheathed on the main shaft, the root part of the blade is in transmission connection with a motor through an electromagnetic clutch, the turntable is in transmission connection with the generator shaft through an electromagnetic clutch, the turntable is in transmission connection with a brake device through an electromagnetic clutch, and the main shaft is in transmission connection with a support frame shaft for installing the case through an electromagnetic clutch. The device can convert wind energy into electric energy which can be stored. Through the control on the electromagnetic clutches, the windward area of the blade and the integral direction of the wind power multiplex device can be respectively regulated, so the rotating speed of the blade of the wind energy multiplex device can be in the proper range, the wind energy is sufficiently utilized, and the power generating efficiency reaches the maximum degree. The motionless state and the rotation of the motor shaft and the blade can be realized through regulating a brake plate to the locking state or the opening state, and the blade is prevented from being damaged when the wind power is too strong.

Description

technical field [0001] The invention relates to a wind energy multiplexing device for wind power generation, in particular to a wind energy multiplexing device capable of adjusting the windward direction and the windward area of ​​blades. Background technique [0002] At present, most wind energy reuse devices are composed of blades directly connected to the shaft of the generator. The blades have only one degree of freedom of rotation, and the bracket is fixed. When the wind direction is suitable, the blades rotate, driving the generator shaft to rotate to generate electricity. However, there are great uncertainties in wind direction and wind speed in nature, which leads to low wind energy utilization efficiency of traditional wind energy reuse devices, and even causes damage to wind energy reuse devices when the wind speed is extremely high. Contents of the invention [0003] In order to overcome the problem of low wind energy utilization efficiency caused by the low de...
