The present application automatically collects rainwater to reduce the cost of water supply. In the tropical rainforest city, there will be a large number of leaves, and there will also be a certain wind force during the rain. When the wind blows, the leaves and other objects will be blown to the top of the three-legged box 401. The sponge block in the water inlet will block the leaves in the rainwater. The outer end surface of the cylindrical sponge block is pressed flat to reduce the friction with the leaves. The leaves and other objects will not accumulate on the top surface of the three-legged box 401. The annular motor 303 drives the notched frame 304 to rotate back and forth by 180 degrees. The notched frame 304 pulls the propulsion rod 302, the arc-shaped slider 301 and the spray washing tile 3 to twist back and forth by 180 degrees, achieving the effect of automatically propelling the spray washing tile 3. The guide rail propulsion assembly drives the lifting ring 5 to move up and down outside the lamp pole 1. The brush assembly inside the lifting ring 5 cleans the dust outside the lamp pole 1. The stepping motor 6 drives the lattice belt 602 to rotate through the transmission wheel 601. The cleaning slider 701 slides synchronously with the lattice belt 602.
