Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generator set maintenance, in particular to a portable detection tool used for wind turbine generator set maintenance. Background Art

[0002] A wind turbine generator set is a system that converts the kinetic energy of wind into electrical energy. The wind turbine generator set includes a wind rotor and a generator. The wind rotor contains blades, a hub, and reinforcements. It has the functions of generating electricity by the blades rotating under wind power and rotating the generator head. When repairing a wind turbine generator set, workers need to carry tools to climb up and the maintenance tools are generally carried in a tool box.

[0003] For example, the utility model disclosed provides a "tool box for wind turbine generator maintenance", and its announcement number is: CN218747655U. The patent includes a box body, a horizontal plate and a vertical plate. Multiple horizontal plates and vertical plates are provided, and multiple horizontal plates and multiple vertical plates are fixed to the inside of the box body perpendicularly. A card frame is fixed above and below the middle of the side surface of the box body, and a magnet block is fixed in the card frame. By fixing magnet blocks above and below the side surface of the box body, and connecting and fixing a rubber sheet with a soft magnet through the inside of the box body, after the box body is carried to a high place, the magnet can be adsorbed on the steel bracket or the surface of the shell to achieve locking of multiple boxes, and the rubber sheet is hugged on the surface of the shell or the bracket and adsorbed tightly by the soft magnet, thereby increasing the locking stability;

[0004] However, the portability of this patent is not high. First, only a shoulder strap is used to carry the toolbox to the top of the wind turbine generator set, and the toolbox will inevitably shake during the carrying process. Secondly, the toolbox is adsorbed on the steel bracket by a magnet, which will restrict the toolbox and make it inconvenient for maintenance workers to move it. After the maintenance work is completed, it is necessary to pull it away from the bracket with force, which is time-consuming and laborious. Therefore, the purpose of this utility model is to enable maintenance workers to carry wind turbine maintenance and inspection tools more conveniently by providing a portable mechanism.
