[0034] Working principle:

[0035] First, take out one set of drain pipes 110 and install them on the wall, then take out another set of drain pipes 110 and place it above the first set of drain pipes 110, so that the plug hole 109 at the bottom is sleeved on the outer surface of the plug column 107 at the top of the first set of drain pipes 110, then turn the nut sleeve 100 downward to make the nut sleeve 100 threadedly connected to the outer surface of the threaded ring 105 of the first set of drain pipes 110, and make the rubber ring 106 installed at the bottom of the first set of drain pipes 110 close to the surface of the connecting ring 104 at the bottom of the second set of drain pipes 110, so that the two sets of drain pipes 110 are fixedly connected together, then take out two sets of sound absorbing layers 102, place the two sets of sound absorbing layers 102 on both sides of the drain pipe 110, and close them inward at the same time, and make the clamping blocks 200 at both ends of one set of sound absorbing layers 102 clamped to the inner cavity of the clamping grooves 202 at both ends of the other set of sound absorbing layers 102, and at the same time, the positioning beads 203 fixedly installed on the surface of the clamping block 200 clamped The two sound absorbing layers 102 are preliminarily connected together by the positioning groove 201 on the inner wall of the clamping groove 202, and then the two sound absorbing layers 102 are fixedly installed together using the cable tie 103, and then the drainage pipe 110 is connected upward in sequence according to the above steps. When connected to the roof surface, the filter barrel 300 is taken out and threadedly connected to the surface of the top threaded ring 105. When it rains, the filter barrel 300 filters larger garbage such as leaves carried in the water flow to prevent it from falling into the inner cavity of the drainage pipe 110, thereby avoiding clogging of the drainage pipe 110. When the water flows into the filter barrel 300, the water flow drives the impeller 304 to rotate, and the impeller 304 drives the two groups of scrapers 301 to scrape the surface of the filter barrel 300, and scrape off the silt attached to the surface of the filter barrel 300 to ensure the smoothness of the water flow. While scraping, the leaves are pushed to the outside to avoid occupying too much area of ​​the filter barrel 300, thereby affecting the speed of the water flow.
