[0002] For the transmission system on the wind turbine generator system, the large flow of lubricating oil (i.e. gear oil) is needed to lubricate, thereby reducing the wear of gears, bearings and other transmission parts. Even if the lubricating oil can effectively lubricate the transmission parts, some wear will occur under the long-time running working condition of the transmission parts, resulting in some metal impurities mixed into the lubricating oil. If these metal impurities are not cleaned in time, the service life of the core components such as the gear box, bearing and lubricating system will be affected. In order to ensure the cleanliness of the lubricating oil, the current wind turbine generator system lubricating system is designed with various filter devices, one of which is to increase a magnetic filter at the main oil return position to adsorb and filter the metal particles in the oil. The conventional magnetic filter has a large volume and weight, and is difficult to disassemble and maintain, and the adsorption and filtration of the metal particles in the oil are insufficient. This may cause some metal particles to re-enter the precise transmission components such as gears and bearings with the lubricating oil, affecting the service life thereof. SUMMARY

The filtering area is connected to the main oil return pipe of the lubricating system. The partition plate has a hollow position for the lubricating oil to pass through. The magnetic attraction filter screen plate is detachably installed on the partition plate and covers the hollow position on the partition plate. The magnetic attraction filter screen plate is provided with a detachable magnetic attraction rod and a filter screen for adsorbing and filtering the metal particles and other impurities mixed in the lubricating oil.

[0005] Further, the hollow position on the partition plate is provided with recessed groove clamping positions on both sides for clamping the magnetic attraction filter screen plate. The magnetic attraction filter screen plate is detachably installed on the recessed groove clamping positions on both sides of the hollow position, and is slidably disassembled and assembled through the recessed groove clamping positions.
