The cantilever frame 702 and the lifting ring 5 on the side wall of the cleaning slider 701 remove dust from the outside of the lamp pole 1 during the up and down movement.

[0039] In a further embodiment of the present invention, Figure 1-8As shown, the brush assembly includes two annular bristles on the inner wall of the lifting ring 5, and the two annular bristles are fixed on the inner wall of the upper and lower ports of the lifting ring 5. A circular array of ball cavities is arranged in the middle position of the inner wall of the lifting ring 5, and steel balls are rotatably arranged inside the ball cavities, and the steel balls are attached to the outer wall of the lamp pole 1.

[0040] In this embodiment, the steel balls on the inner wall of the lifting ring 5 reduce the friction with the lamp pole 1, thereby preventing the lamp pole 1 and the lifting ring 5 from being stuck.

[0041] Working principle: the annular propulsion assembly drives the arc-shaped slider 301 and the spray-washing tile 3 to twist back and forth 180 degrees. When the spray-washing tile 3 is at the top of the lamp holder 2, the spray-washing tile 3 will not interfere with or block the light emitted by the lamp holder 2. When the insect entity at the bottom of the lamp holder 2 needs to be cleaned, the spray-washing tile 3 will be twisted to the bottom of the lamp holder 2, and the pinholes on the inner arc surface of the spray-washing tile 3 will start to spray cleaning liquid to wash away the insect corpses and dust on the lamp, achieving the effect of barrier-free cleaning of the lamp. Compared with the lamp cleaning equipment in the prior art, the previous lamps were relatively large in size, and these cleaning equipment would have a certain impact on the light source emitted by the lamp. The shielding effect will affect the full emission of the light source of the lamp. The spray-washing tile 3 of the present invention will be hidden on the back of the lamp stand 2 when not in use, which will not affect the irradiation range of the lamp stand 2. Every time it rains, rainwater passes through the rainwater filtering components on the two opposite slopes on the top of the tripod box 401 and enters the interior of the tripod box 401. The rainwater inside the tripod box 401 is collected into the cleaning box 4 along the riser 403. Compared with the water replenishment method of the street lamp cleaning water tank of a solar street lamp with self-cleaning solar panels disclosed in the prior art 202221891590.8, the previous street lamp cleaning water tank needs to use self-cleaning The present invention automatically collects rainwater to reduce the cost of water replenishment. There will be a large number of leaves in the city in the tropical rain forest. There will also be a certain amount of wind during the rain. When the wind blows, the leaves and other objects will be blown to the top of the tripod box 401. The sponge block inside the water inlet will block the leaves in the rain. After the outer end surface of the cylindrical sponge block is pressed and smoothed, the friction with the leaves can be reduced, and the leaves and other debris will not accumulate on the top surface of the tripod box 401. The surrounding motor 303 drives the notch frame 304 to rotate back and forth 180 degrees, and the notch frame 304 will pull the propulsion rod 302, the arc-shaped slider 301 and the spray tile 3 together. Twisting back and forth one hundred and eighty degrees, the effect of automatic propulsion and spray cleaning of 3 watts is achieved. The guide rail propulsion assembly drives the lifting ring 5 to slide up and down on the outside of the lamp pole 1. The brush assembly on the inside of the lifting ring 5 will clean the dust on the outside of the lamp pole 1. The stepper motor 6 drives the lattice belt 602 to operate through the transmission wheel 601. The cleaning slider 701 slides synchronously with the lattice belt 602. The cantilever frame 702 on the side wall of the cleaning slider 701 and the lifting ring 5 remove the dust on the outside of the lamp pole 1 during the up and down movement. The steel balls on the inner wall of the lifting ring 5 reduce the friction with the lamp pole 1 and prevent the lamp pole 1 and the lifting ring 5 from being stuck.
