Self-cleaning wind turbine generator filter screen

The utility model relates to the field of wind turbine generators. The self-cleaning wind turbine generator filter screen comprises an installation frame arranged on the periphery of the filter screenin a sleeving mode, a guide rail located on the air exhaust side of the filter screen and parallel to the filter screen and a baffle rotationally connected to the installation frame and used for covering an air outlet of the filter screen are arranged on the installation frame, and the guide rail is located between the filter screen and the baffle; a nozzle is movably connected to the guide railin a matched mode and is opposite to the filter screen. Pollutant particles accumulated on the air inlet side of the filter screen can be blown away by high-pressure gas sprayed out of the nozzle, andthe purpose of automatically cleaning the filter screen is achieved. 本实用新型涉及风电机组领域，具体涉及了一种自清洁风电机组滤网，包括套设于滤网外周的安装架，安装架上设有位于滤网的排风侧且平行于滤网的导轨以及转动连接于安装架并用于遮盖滤网的排风口的挡板，其中，导轨位于滤网和挡板之间；导轨上活动地配合连接有喷嘴，喷嘴和滤网相对设置。堆积在滤网进风侧的污染颗粒物会被喷嘴喷出的高压气体
