A wind turbine blade cleaning device

Abstract

The invention provides a fan blade cleaning device of a wind driven generator. The fan blade cleaning device comprises a wind power generator set, a positioning frame, an electric suction disc, a winch type rope tightening device, an upper framework plate, a lower framework plate, a rotating roller, a gear pump set, fan blades, a fastening bolt buckle, a bearing rotating shaft, a hydraulic telescopic frame, a rope passing hole, a water storage tank, a first rope clamping wheel, a second rope clamping wheel, an active driving tooth, a chain, a right-angle transmission teeth, a passive driving gear, a brush head and a communicating pipeline; the fan blades is movably connected above the wind power generator set, the positioning frame is movably connected outside the fan blades, the positioning frame is movably connected to the end portion of each fan blade respectively, and a steel wire rope is wound on the surface of the winch type rope tightening device. The fan blade cleaning device depends on the rotation of the fan blades, so that the upper framework plate and the lower framework plate are continuously converted by the gravity potential energy, and the fan blade cleaning deviceare sequentially used as a power source to enable the device to clean the fan blades, so that the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a fan blade cleaning device for wind power generators. 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 limit safety mechanisms, and energy storage devices. The working principle of wind turbines is relatively simple. Rotating under the action of the wind, it 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. [0003] The windward side of the wind turbine blade is the main source of power for the generator, and the smoothness of the back of the blade is th...

Problems solved by technology

[0005] The purpose of the present invention is to provide a wind power generator fan blade cleaning device to solve the problem that due to the mainstream blade type is 126 / 110 / 114, the corresponding blade size is 68m, 54m, 56m; the diameter of the largest fan blade is now more than 70 meters It is equivalent to the wingspan of a Boeing aircraft. It is already very difficult to install a fan blade of this quality and area. It is too expensive to disassemble it and clean it. Most of the existing cleaning methods are wind turbines. Shut down, and then the crane drives the staff to use high-pressure water guns to clean, which is time-consuming and laborious, and the degree of cleaning is not high
