[0033] Principle of use: The bottom shell 1 of the rain gutter is poured on the roof during installation. When in use, the position of the filter cover 7 is adjusted according to the actual situation of the roof water accumulation.

It is only necessary to screw the adjusting nut 10. The downward movement of the adjusting nut 10 drives the mounting plate 6 and the filter cover 7 to move downward. When the filter cover 7 moves downward, the opening position of the guide component 4 becomes smaller to prevent impurities from entering. Similarly, when there are no obvious impurities in the accumulated water, the filter cover 7 can be fully lifted up to improve the drainage efficiency of the accumulated water.
