Braking device of bladeless wind driven generator

Abstract

The invention discloses a braking device of a bladeless wind driven generator. The braking device comprises a stator and a rotor, the rotor moves up and down in the stator, brake block assemblies are symmetrically arranged on a mounting platform of the stator, each brake block assembly comprises brake blocks arranged on the two sides of the rotor, the brake blocks on the two sides are movably connected to a second connecting rod and a fourth connecting rod respectively, one end of the second connecting rod is hinged to a first fixing seat, the second connecting rod is connected with the first connecting rod through a third connecting rod, the two ends of the third connecting rod are hinged to the second connecting rod and the first connecting rod respectively, the side, close to the third connecting rod, of the first connecting rod is hinged to the second fixing seat, the other side of the first connecting rod is connected with a rotating disc, and the rotating disc is connected to a stepping motor; one end of a fourth connecting rod is hinged to a third fixing seat, the other end of the fourth connecting rod is connected with the first connecting rod through the third connecting rod, and the two ends of the third connecting rod are hinged to the fourth connecting rod and the first connecting rod respectively. The stable and effective braking effect is achieved, and impact on the whole device caused by sudden braking is prevented.

Description

technical field [0001] The invention belongs to the technical field of wind power generators, and in particular relates to a braking device for a bladeless wind power generator. Background technique [0002] Wind energy is a renewable, non-polluting natural energy with huge reserves, which has been highly valued by countries all over the world. For example, from 2002 to 2015, the global installed capacity of wind power increased from 17.4GW to 432.9GW, an increase of about 23 times. The basic principle of wind power generation is to use the wind to drive the wind rotor blades to rotate, and then increase the speed of rotation through the speed increaser, and then promote the generator to generate electricity. [0003] For traditional wind turbines, blades are the key core components of wind turbines, and horizontal axis wind turbines generally have 2 to 4 blades. The amount of power generated by a wind turbine largely depends on the size of the blades. The larger the blade ...

Problems solved by technology

[0004] Because wind turbines are generally installed in areas with relatively high wind speeds such as mountain tops or spacious plains and forests, and these areas are often places where birds gather or migratory birds migrate, when the wind rotor rotates, the area swept by the wind rotor blades will directly It will affect the flight of birds, and even cause the death of birds; and more and more wind turbines are installed on the top of mountains and other places close to the villages where people live. The installation site causes noise and visual pollution, especially in the dead of night when the wind turbines are running, the noise spreads farther and is more likely to affect people's sleep and rest. Therefore, traditional wind turbines will bring great harm to the natural ecological environment and local nearby residents. Influence, based on this, we have proposed a bladeless wind power generator device (patent No. CN201710295283.0 Chinese patent), using the wind tower to replace the blades in the traditional wind power generator to obtain wind energy, vibrating once in the wind tower That is, within one cycle of deflection, the mover moves up and down twice in the stator to cut the magnetic force line, so that the vibration frequency of the wind tower can be doubled. When the wind force increases, the wind tower deflects periodically Both the frequency and angle of the moving element will increase, and the frequency and the moving amount of the mover will increase, that is, the magnetic line cutting will increase, and the amount of magnetic line cutting will increase, so that the power generation will also increase.
