A high-efficiency wind turbine with a small footprint and cost savings

Abstract

The invention relates to an efficient wind generating set capable of occupying a small area and saving the cost. The wind generating set comprises a top plate, a yaw box, a plurality of power generating units, two bases and two tower frames, the yaw box is internally provided with a yaw mechanism, and the yaw mechanism comprises a driving unit and a plurality of connecting units. The outer sides of the tower frames are provided with antitheft doors and a plurality of openings, and a plurality of climbing units are arranged in the tower frames and comprise pedals, first sleeve rings, second sleeve rings, inserting rods, limiting blocks, two rotating units and a plurality of oblique rods. According to the efficient wind generating set capable of occupying the small area and saving the cost, the multiple power generating units are supported through the two tower frames, and the yaw mechanism drives generator rooms to rotate while the occupied area is reduced; the positions of blades are adjusted, the power generating efficiency is improved, and not only that, the interiors of the tower frames communicate with the exteriors of the tower frames while climbing of workers is facilitated through the climbing units; and breathing health of the workers is ensured, the climbing units adopt materials on the tower frames, and thus the cost of the generating set is effectively reduced.

Description

technical field [0001] The invention relates to the field of wind power generating equipment, in particular to a high-efficiency wind power generating set with a small footprint and low cost. 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 (including devices), steering devices (tail fins), 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 ...

Problems solved by technology

[0003] In order to make full use of wind energy resources, people usually set multiple wind turbines in areas with abundant wind energy resources. In a single wind power generating set, multiple towers are required to support the operation of the equipment, which will not only increase the floor area, but also increase the production, transportation and installation costs of the set. When multiple generators fail in the set, Workers also need to climb on each tower in turn, which increases the maintenance time and intensity, making the maintenance process very troublesome. Not only that, most of the climbing devices of wind turbines are straight ladders, and they are fixed in the towers. Since the tower is a sealed device, the air inside the tower is sultry and turbid, which will not only affect the breathing health of the staff when climbing, but also the sultry and turbid air inside the tower will accelerate the fatigue of the staff. Although the addition of a straight ladder inside can realize the function of the staff climbing to the top, it increases the cost of the straight ladder and is not conducive to the safe climbing of the staff, which leads to the fact that the existing wind turbines are not practical in the application process. reduce
