Wind-driven generator with high power generation efficiency and good heat dissipation effect

Abstract

The invention discloses a wind-driven generator with high power generation efficiency and good heat dissipation effect. The wind-driven generator includes a machine shell and a low-speed shaft. The low-speed shaft is rotatably and laterally installed at the middle position inside the machine shell, the low-speed shaft is fixed into the machine shell through bearings, and the bearings are distributed on both sides of the low-speed shaft. The inside of the machine shell includes a power generation device and a heat dissipation system. The power generation device includes a main generator, an auxiliary generator, a fixed frame, a driven disk, a belt, a rotational speed sensor, a driving disk, a transmission rod, a driven tooth, a rotating tooth, a speed measuring disk, an electro-hydraulic push rod and a rotating wheel; and the main generator is fixed to the lower end of the left side in the machine shell. According to the wind-driven generator, when a gap exists between the belt and thedriving disk, when the rotational speed sensor detects that the rotational speed is too high, the electro-hydraulic push rod presses the belt to enable the belt to be in contact with the driving disk,the auxiliary generator is driven to generate electricity, meanwhile, the resistance during rotation of the low-speed shaft is increased to play the role of speed reduction, fan blades are arranged to assist heat dissipation, and the power generation efficiency is high and the heat dissipation effect is good.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator with high power generation efficiency and good heat dissipation effect. Background technique [0002] At present, energy is the material basis for the survival of human society. The development and prosperity of modern society are closely related to the development of energy. With the economic development and population increase of all countries in the world, energy consumption is increasing. Due to social pressure, people have turned their attention to the sustainable development of new energy represented by wind energy, ocean energy and solar energy. Wind energy and tidal current energy are green energy with large reserves and no pollution. The development and utilization of wind energy and tidal current energy play a very important role in alleviating the energy crisis and reducing environmental pollution.

Problems solved by technology

[0003] The blades of the wind turbine are more than 20 meters long. If it turns too fast, it will put a lot of pressure on the base, and at the same time cause the generator to collapse or the blades to break and cause an accident. Therefore, a brake device will be installed inside the wind turbine , so as to reduce the rotation speed of the fan blades, but using the brake device to slow down the fan blades will cause the loss of wind energy, making the power generation efficiency of the wind turbine generator not high enough
