[0046] When the utility model is used:

[0047] Rainwater collection stage: the rainwater of the roof first flows to the gutter 1. Since the gutter 1 is designed by stainless steel sheet metal, and the sheet metal at the front and rear ends is provided with a bending groove, the design helps to guide the rainwater to concentrate and gather, and prevents the rainwater from splashing in all directions. Meanwhile, the reserved groove 11 is arranged at the lowest point of the inner side bottom of the gutter 1, so that the rainwater can flow to the reserved groove 11 naturally.

[0048] Connection and sealing stage: at the reserved groove 11 of the gutter 1, the clamping pieces 12 of the integrated sheet metal pass through the cross array arranged clamping grooves 211 at the top outer side of the straight falling pipe 21, and are bent by 90 degrees. In this way, the top of the straight falling pipe 21 is installed in communication with the gutter 1 through the cooperation of the clamping pieces 12 and the clamping grooves 211, and a sealing gasket is arranged at the connection between the downpipe 2 and the gutter 1, so as to ensure the sealing of the connection and prevent the rainwater from leaking.

Since the height of the top of the transmission rod 32 is higher than the height of the top of the downpipe 2, when the sundries and sludge pass through the cutting frame 33, the cutting frame 33 cuts and crushes them, preventing the sludge from accumulating in the pipeline. Since the cross-sectional size of the cutting frame 33 is smaller than the inner diameter size of the straight falling pipe 21, the cutting frame 33 can rotate freely in the straight falling pipe 21 and will not hinder the normal flow of the rainwater. The cut and crushed sundries and sludge continue to flow downward with the rainwater, and are discharged through the side pipe 22 connected and installed at the front bottom opening of the straight falling pipe 21, thereby effectively preventing the pipeline from being blocked and ensuring smooth drainage.
