[0013] The utility model has the following advantages:

[0014] 1. By installing a frame and adding a filtering structure, the impurities leaking into the first filter cloth can be blocked and filtered to avoid the purity of the impurities in the water body. The fan blades can be driven to rotate when the water flows in, so that the brush rod can clean the outer surface of the inner filter cloth to avoid blockage.

[0015] 2. The positioning frame can be disassembled and installed through the installation mechanism, which is convenient for later replacement. BRIEF DESCRIPTION OF THE DRAWINGS
