Description

Technical Field

[0001] The utility model relates to the technical field of wind power generators, in particular to a lubrication structure for a driving component of a wind power generator. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of a wind rotor, a generator (including a device), a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind, and it converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft. In a broad sense, wind energy is also solar energy, so it can also be said that a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium.

[0003] The existing patent CN220851705U proposes a lubrication structure for the driving parts of a wind turbine. The utility model includes an oil storage box, a control box is installed at the top of the oil storage box, a controller is installed on one side of the control box, a lubrication pump is installed on the other side of the control box, one end of the lubrication pump is connected to an oil inlet, one end of the oil inlet extends to the bottom of the oil storage box and is installed with a filter plate, the bottom of the oil storage box is rotatably connected to a rotating shaft, the top of the rotating shaft is fixedly connected to a cleaning scraper, and the top of the cleaning scraper and the bottom of the filter plate fit each other, one side of the lubrication pump is connected to an oil outlet, and the oil outlet is connected to an oil filling pipeline. The device facilitates the rapid cleaning of the filter plate surface on the oil inlet of the lubrication pump through the coordinated use of the driving motor, the rotating shaft and the cleaning scraper, so as to avoid the impurities in the lubricating grease adhering to the filter plate surface, causing the filter plate to be blocked, resulting in difficulty in oil inlet, and reducing the working efficiency of the lubrication system.

[0004] However, although the existing patent CN220851705U facilitates the rapid cleaning of the filter plate surface on the oil inlet of the lubrication pump through the coordinated use of a driving motor, a rotating shaft and a cleaning scraper, thereby preventing impurities in the lubricating grease from adhering to the filter plate surface and causing clogging of the filter plate, resulting in difficulty in oil supply and reducing the working efficiency of the lubrication system, the various driving components of the wind turbine may consume different amounts of lubricating oil, and unified replenishment of lubricating oil may cause some components to be obstructed in operation.
