Offshore wind driven generator with protection function

Abstract

The invention discloses an offshore wind driven generator with a protection function, and relates to the technical field of wind power generation. The offshore wind driven generator comprises a wind driven generator main body and fan blades, the interior of the wind driven generator main body is fixedly connected with a sealing plate, and the interior of the wind driven generator main body is fixedly connected with a temperature sensor. According to the offshore wind driven generator with the protection function, when the temperature sensor detects that the internal temperature of the wind driven generator main body is too high, a draught fan is controlled to start to operate, the draught fan drives external airflow to enter the wind driven generator main body from an air inlet, the airflow is exhausted from an air outlet after heat dissipation, a filter screen can filter dust and impurities contained in air, meanwhile, the airflow drives an impeller to rotate when exhausted from the air outlet, a cleaning brush can rotate to clean meshes of the filter screen, and the situation that the meshes of the filter screen are blocked, and consequently the heat dissipation effect is affected is prevented.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an offshore wind power generator with protection 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 the 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 existing offshore wind power generator is in use, the operation of the generator will generate a large amount of heat. If the heat dissi...
