Environment-friendly roof drainage structure

The utility model provides an environment-friendly roof drainage structure, relates to the technical field of drainage, and aims to solve the problems that when an existing drainage structure is used, a structure for fixing a drainage pipeline is incomplete, and a drainage pipe is inconvenient to guide and install. The collecting mechanism is a building roof body, and a drainage mechanism is mounted at the bottom of the collecting mechanism; the drainage mechanism is mounted in a mounting groove in the collection mechanism through a leakage piece; a filtering mechanism is mounted in the drainage mechanism; the mounting groove is formed in the bottom end in the collecting mechanism; the fixing piece is of a circular structure and is installed at the bottom of the collecting piece. During installation, the leakage part and the pipe fitting are inserted into the installation groove, the pipe fitting can penetrate through the fixing part at the moment, then the pipe fitting is vertically installed, the situation
