Description

Technical Field

[0001] The utility model belongs to the technical field of lubricating oil filtering devices, and in particular relates to a debris removal and collection structure for a lubricating oil filtering device of a wind turbine generator set. Background Art

[0002] The primary role of lubricating oil in a generator is to reduce direct contact and friction between machine parts, thereby reducing wear. Lubricating oil will inevitably be mixed with various impurities during the circulation process, such as particles, mud, metal chips, etc. If these impurities are not removed in time, they will cause wear to the moving parts inside the equipment and even cause equipment failure. In the prior art, generators are usually equipped with lubricating oil filtering devices. During the filtering process, impurities tend to accumulate on the filter net, causing inconvenience in cleaning. Long-term accumulated impurities will clog the filter net and affect the filtering effect. The process of cleaning impurities on these filter nets is quite cumbersome, resulting in the filter nets often being regarded as disposable consumables that need to be replaced frequently, increasing maintenance costs and complexity.
