Description

Technical Field

[0002] Wind turbine blades are components of wind turbines that convert the kinetic energy of wind into mechanical energy, which ultimately drives the generator to generate electricity. These blades are usually mounted on the rotor of a wind turbine. They are designed to capture the kinetic energy of wind to the greatest extent possible and convert it into rotational motion. In order to clean them for subsequent maintenance and increase their service life, blade cleaning devices refer to equipment used to clean and maintain wind turbine blades. These devices are designed to ensure that the blades of wind turbines remain clean to maintain their performance and efficiency, and to reduce the accumulation of particles or dust that may affect the operation of the generator.

[0003] After searching: Chinese patent announcement number: CN216174549U, it relates to the technical field of wind power blade cleaning, and discloses a cleaning device for wind turbine blades, which specifically comprises a base, and two groups of movably connected universal wheels are arranged on the lower end surface of the base, and a support column is arranged on the upper end surface of the base at an end away from the wind power blade body, and a fixed column is arranged on the top end surface of the support column, and an electric telescopic rod is arranged on the side of the support column close to the wind power blade body, and a movably connected slide rail 1 is arranged on the lower end surface of the fixed column, and a slider 1 matched with the slide rail 1 is arranged on the lower end surface of the slide rail 1, and a motor housing is arranged on the lower end surface of the slider 1, and a motor shaft of the motor is provided with a movably connected roller, and a movably connected slide rail 2 is arranged on the upper end surface of the slide rail 2, and a slider 2 matched with the slide rail 2 is arranged on the upper end surface of the slide rail 2. The utility model aims to solve the problem of low efficiency of manual cleaning of wind power blades.

[0004] The above patent specification states that "the connecting rod 73 is movably connected to the fixed block 1 71 and the fixed block 2 72 through internal and external threads. The connecting rod 73 is provided with a rotating handle 74 at the end away from the fixed block 1 71, and the rotating handle 74 is detachably connected to the connecting rod 73.
