Roof wind driven generator with windproof function

Abstract

The invention relates to a roof wind driven generator with a windproof function. The roof wind driven generator comprises a supporting column, a fan blade mechanism, a gearbox, a low-speed rotating shaft, an electricity generation mechanism, a PLC, a waterproof bucket and a lifting mechanism. The fan blade mechanism comprises fan blades, a high-speed rotating shaft, an encoder and a telescopic assembly. The telescopic assembly comprises a fixing block, a motor, a lead screw and a walking rod. The lifting mechanism comprises a lifting block, a hydraulic box, a hydraulic groove and a pump body. According to the roof wind driven generator with the windproof function, the design structure is ingenious, practicability is high, and the encoder detects the rotating frequency of the high-speed rotating shaft when wind power is too high; when the rotating frequency is too large, the distance between every two adjacent fan blades is reduced through the PLC under the assistance of the telescopic mechanism, so that the sectional area for wind is reduced, the speed of the fan blades is reduced, and the problem that equipment is damaged due to the too large rotating frequency is avoided; and when the rotating frequency is still too large, at the moment, wind power is quite large, the fan blades are moved by the lifting mechanism into the windproof bucket, and the roof wind driven generator with the windproof function is prevented from being broken by high wind.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a roof wind power generator with windproof function. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of components such as wind rotors, generators, steering devices, towers, speed limiting safety mechanisms, and energy storage devices. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates to generate electricity under the drive of the wind rotor shaft. [0003] When the wind wheel rotates too fast, the firmware of the wind generator will be damaged, reducing the service life of the wind generator, and the wind resistance ...
