The scraper body includes a scraper body handle and a scraper body scraper. Old oil on the gear wall is removed by manually pushing the handle up and down. This embodiment is detailed below:
[0029] Figure 2 This illustration shows the main structure of a tool for cleaning and applying grease to the pitch and yaw gear rings of a wind turbine generator, as provided by this utility model. The main body of the lubricator is a tool for storing and applying lubricating oil. Its material can be metal, high-strength plastic, or 3D printed material. An oil injection pipe is provided on the back side, connected to a lubricating oil injection pump via a pipeline. Specifically: the main body of the lubricator has an arc-shaped plate structure. Its back side has a handle 1 and multiple spaced oil delivery pipes 9. Its front side has spaced gear-shaped scrapers for contact with the industrial gears to be lubricated. Each gear-shaped scraper has a groove 2 in the lubricator body and an oil outlet 3 connected to the oil delivery pipes 9. The groove 2 is used to store lubricating oil during use. Limiting plates 10 are provided on the upper and lower sides of the lubricator body to limit the relative position of the gear-shaped scrapers when they are in contact with the industrial gears. The limiting plates 10 also have vents 11 to ensure even application of lubricating oil. When lubricating oil overflows from the vents, it indicates that the application of lubricating oil has been completed.
[0030] The oil distributor has a hollow tubular structure as its main body, with nine oil outlets on one side. Each oil outlet has a corresponding independent regulating valve on its back side. Turning the regulating valve clockwise closes the oil outlet, and turning it counterclockwise opens the outlet, forming a multi-channel distribution structure. The oil outlets of the hollow tubular structure are connected to the oil delivery pipe 9 on the back side of the oil injector body via a flexible hose. The oil distributor is connected to the lubricating oil injection pump 6 through the oil inlet 5 at its end. The lubricating oil injector 7 injects lubricating oil into the oil distributor through the lubricating oil injection pump 6.
