Wind wheel provided with speed complementing mechanism and used for wind power generation

Abstract

The invention relates to a wind energy generating unit and provides a wind wheel provided with a speed complementing mechanism and used for wind power generation. The wind energy generating unit comprises wind blades, a wind blade top plate, a wind blade bottom plate, a central shaft, a power source, a rack, the speed complementing mechanism, a rotating speed sensor and a controller. The wind blades are fixed to the side face of the wind blade top plate and the side face of the wind blade bottom plate. The wind blade top plate and the wind blade bottom plate are fixed to the central shaft. The central shaft is connected with the rack. The speed complementing mechanism comprises a stator and a rotor. The stator comprises a tray and coils fixed to the tray. The rotor is fixed to the other side face of the wind blade top plate or the other side face of the wind blade bottom plate. The stator is fixed to the central shaft or the rack and opposite to the rotor. The rotating speed sensor is arranged on the portion close to the wind blade top plate or the wind blade bottom plate. The controller is connected with the rotating speed sensor and the power source. The coils are electrically connected with the power source. By the adoption of the wind energy generating unit, breeze energy can be fully used; and when the wind speed is unstable, the stable electric quantity can be obtained, the structure is simple, mounting and overhauling are convenient, the manufacturing cost is low, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to a wind energy generating set, in particular to a device for increasing the rotating speed of a wind rotor of the wind energy generating set. Background technique [0002] As a new energy source, wind energy is the most abundant energy available to human beings. Inexhaustible, inexhaustible, and a clean energy source. During development and utilization, there will be no waste residue, waste water, waste gas, and no noise, nor will it affect the ecological balance. It will definitely not cause pollution and public nuisance. [0003] However, wind energy also has some disadvantages. When the wind is small, it is difficult to start the wind blades and rotors, and the wind speed is very unstable, resulting in unstable electricity generated by wind energy. In order to overcome the difficulties in popularization and application, people have made great improvements in selecting suitable materials, or combining them with other energy...

[0003] However, wind energy also has some disadvantages. When the wind is small, it is difficult to start the wind blades and wind wheels, and the wind speed is very unstable, resulting in unstable electricity generated by wind energy.

In order to overcome the difficulties in popularization and application, people have made great improvements in selecting suitable materials, or combining them with other energy sources. However, it is difficult to fundamentally solve the problem, resulting in the development of wind energy, water energy and tidal energy. application, limited
