A wind turbine with high power generation efficiency that is easy to clean

Abstract

The invention relates to a convenient-to-clean wind power generator with high power generation efficiency. The convenient-to-clean wind power generator comprises a base, a tower, a platform, a cabin,a hub, a cleaning mechanism and multiple blades. The cleaning mechanism comprises a lifting mechanism, a lifting plate and two erasing mechanisms. The lifting mechanism comprises a driving assembly and two lifting assemblies. Each lifting assembly comprises a first bevel gear, a screw rod, a sliding block, a pillar, a telescopic frame, a hinge block, a sliding ring and a sliding rail. Each erasingmechanism comprises two erasing assemblies. Each erasing assembly comprises a support plate, a supporting assembly, an extending-and-contracting assembly, a connecting plate and a cleaning block. Theconvenient-to-clean wind power generator with high power generation efficiency drives the lifting plate to ascend through the lifting mechanism, dust is erased by the cleaning blocks when each bladerotates and passes through the corresponding two cleaning blocks, and the power generation efficiency is improved; and moreover, in the erasing mechanisms, the support plates can be fixed by fixing units, the rotation of the support plates is facilitated through hinge units, cleaning of the cleaning blocks by people is facilitated, the cleaning capacity of the cleaning blocks is recovered, and thepracticability of equipment is improved.

Description

technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a wind power generator that is easy to clean and has high power generation efficiency. 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...

Problems solved by technology

[0003] The blades of wind turbines play a vital role in the power generation process of the equipment, but with the long-term operation of the equipment, the surface of the blades will absorb a large amount of dust and impurities, which will create resistance to the wind and reduce the The angle of attack of the wind on the blades reduces the power generation by 7%-10%. In addition, because the dirt is not evenly distributed on the blades, it will also increase the aerodynamic imbalance and mass imbalance, and the blades that absorb dust It will no longer be smooth, and the rough surface makes the blades more likely to be "torn" by the wind. Therefore, people need to clean the blades of the wind turbine in time, but because the blades of the wind turbine are often in a rotating state and there is a distance from the tower A certain horizontal distance leads to an increase in the difficulty of cleaning the blades, which in turn reduces the practicality of existing wind turbines
