Wind driven generator having speed adjusting function

Abstract

The invention relates to a wind driven generator having a speed adjusting function. The wind driven generator having the speed adjusting function comprises a tower body, a shell, a fan mechanism, a gearbox and a power generation mechanism. The gearbox comprises a variable-speed gear assembly, a leftward and rightward adjusting assembly, a PLC and a frontward and backward adjusting assembly. The variable-speed gear assembly comprises a variable-speed rotating shaft, a first variable-speed gear and an infrared receiver. The leftward and rightward adjusting assembly comprises an infrared transmitter, a bearing, a sliding block, a lead screw, fixed blocks, a first motor, a shifting block and a base. The frontward and backward adjusting assembly comprises a second motor, a round gear and a strip gear. According to the wind driven generator having the speed adjusting function, a power generation system in the power generation mechanism sends an instruction to the PLC, the PLC can move a high-speed gear in the power generation mechanism to be meshed with an appropriate variable-speed gear through a frontward and backward adjusting mechanism and a leftward and rightward adjusting structure, and it is guaranteed that the power generation mechanism is in the most stable power generation state; and, when wind force is large, the wind driven generator having the speed adjusting function can be protected.

Description

technical field [0001] The invention relates to the field of wind power generator equipment, in particular to a wind power generator with a speed regulating 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. In a broad sense, wind energy is also solar energy, so it can also be said that a wind generator is a thermal energy utilization generator that uses the sun as...

AI Technical Summary

Problems solved by technology

[0003] When the wind power of the wind turbine is strong, the wind rotor shaft will rotate too fast, which is easy to cause damage to the equipment. When the wind power is low, the resistance between the gears is relatively large, causing the fan blades to not rotate and wasting wind energy.
