Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a maintenance device for a wind turbine set. Background Art

[0002] Wind power generation, in layman's terms, is the conversion of wind kinetic energy into mechanical kinetic energy, and then the conversion of mechanical energy into electrical kinetic energy. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to make the generator generate electricity. Wind turbines are usually installed in the cabin. As the equipment is used for a longer period of time, some faults will occur, so maintenance work is required. During maintenance, maintenance equipment, tools, and some parts and materials for repair and replacement are required. Traditional maintenance equipment, tools, and materials are usually placed in a maintenance work bag. Although it is convenient for staff to carry, it lacks regularity and needs to be searched when used. It is not convenient and standardized to use. Moreover, if they are mixed together, they will collide with each other during movement, which is prone to collision damage. Therefore, a fault detection device that can be regularly stored is needed to solve such problems.

[0003] The existing patent CN219119382U discloses a wind turbine fault detection device, which clamps the detection device body through a pressure plate, closes the protective cover, rotates the round rod, screws the screw into the threaded hole, fixes the position of the protective cover, and then moves the device by hand-carrying the handle, which solves the problem that most detection devices are inconvenient to carry and ensures that the fault of the wind turbine can be detected in time; by setting the adsorption component, the detection device is placed more stably, and the safety of the detection device is improved. However, considering its overall structure, its functionality is still insufficient. First, its structure lacks a stable working platform when performing detection and maintenance. When performing maintenance operations, it is impossible to perform detection and disassembly and maintenance work safely and smoothly, and it is also not convenient to use; secondly, the structure lacks auxiliary lighting function. The generator set is located in the cabin. When performing maintenance, some positions are relatively dim, or when performing maintenance in some light-poor hours, it is easy to affect the operation due to unclear vision.
