Wind-driven generator capable of being automatically cleaned

Abstract

The invention discloses a wind-driven generator capable of being automatically cleaned, which comprises a tower and a fixed block with a moving groove inside, wherein the fixed block is provided withan arc-shaped groove and a straight groove which are connected with the moving groove, the arc-shaped groove is communicated with the straight groove, the tower is vertically provided with a verticalcolumn, the tower is rotatably provided with a rotating blade, the inner wall of the vertical column is fixed with a stepping motor, an output shaft of the stepping motor is connected with a rotatingmechanism and a transmission mechanism located below the rotating mechanism, the fixed block is fixed on the rotating mechanism, and the internal part of the fixed block is rotatably provided with a connecting shaft which passes through the side walls of the fixed block and the vertical column and is then connected on the transmission mechanism. The advantage lies in that the sponge on a connecting rod is driven to move by the stepping motor without climbing so as to automatically clean the rotating blade and the upper part of the vertical column, thereby preventing the danger.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a wind power generator that can be cleaned automatically. Background technique [0002] The rotating 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 rotating blades will absorb a large amount of dust and impurities, which will create resistance to the wind, Decreases the angle of attack of the wind on the rotating blades, reducing the power generation by 7-10%, in addition, it also increases the aerodynamic imbalance and mass imbalance since the dirt will be distributed unevenly on all the rotating blades , and the rotating blades that absorb dust will not be on a smooth, rough surface that makes the rotating blades more likely to be "torn" by the wind. Therefore, people need to clean the rotating blades of the wind turbine in time, but because the rotating blades of the wind...

[0002] The rotating 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 rotating blades will absorb a large amount of dust and impurities, which will create resistance to the wind, Decreases the angle of attack of the wind on the rotating blades, reducing the power generation by 7-10%, in addition, it also increases the aerodynamic imbalance and mass imbalance since the dirt will be distributed unevenly on all the rotating blades , and the rotating blades that absorb dust will not be on a smooth, rough surface that makes the rotating blades more likely to be "torn" by the wind. Therefore, people need to clean the rotating blades of the wind turbine in time, but because the rotating blades of the wind turbine often It is in a rotating state and has a certain horizontal distance from the tower. During the cleaning process, it is difficult for people to fix the rotating blades, and only the side of the rotating blades close to the tower can be cleaned, and it will be very dangerous. For the rotating blades On the side away from the tower, because people cannot reach the rotating blades when climbing on the tower, it is difficult to clean the side of the rotating blades away from the tower, and it is difficult to clean the rotating blades of the wind turbine thoroughly and effectively
