[0002] The hydraulic system of a wind power gearbox is an important part to ensure the normal operation of the wind power gearbox. It is mainly used to provide lubrication, cooling and control functions. The hydraulic oil is transported to each required part through an oil pump to achieve full lubrication of gears and bearings, reduce friction and wear, and extend the service life of components. In order to filter out tiny impurity particles, colloids, metal debris and other pollutants in the hydraulic oil, a fine filter is installed in the hydraulic system. Through this fine filtration, the wear and blockage of hydraulic components caused by impurities can be effectively prevented, and the stable operation of the hydraulic system can be ensured. However, after the fine filter is used for a long time, a large amount of impurities accumulate inside and need to be disassembled and cleaned. Most existing fine filters are fixed to the hydraulic system by bolts and require special tools to disassemble the fine filter, which increases the maintenance steps of the equipment and consumes a lot of time.
