The movable seat 404 moves towards the fixed seat 402 under the reset action of the connecting spring 405. During the movement of the movable seat 404, the connecting rod 403 is lifted. The connecting rod 403 lifts the cleaning rack 301. During the lifting process, the cleaning rack 301 rotates towards the sign 2 along the rotating shaft 401. The cleaning rack 301 is squeezed by the sign 2. During the squeezing process, the cleaning rack 301 rotates away from the sign 2 along the rotating shaft 401, squeezing the connecting rod 403. The connecting rod 403 drives the movable seat 404 to stretch the connecting spring 405 and move away from the fixed seat 402. Achieve rotational drive.

[0025] Working principle of the invention: Before use, the gas station eaves sign is fixed to the gas station eaves by passing several screws through several mounting holes 6 of the top support frame 1 in sequence. During the use of the gas station eaves sign, the first motor 101 is started, driving the output end of the first motor 101 to rotate, which in turn drives the screw 103 to rotate, causing the movable seat 104 to move towards the mounting end on the screw 103, thus moving the sign 2 towards the mounting end. As the sign 2 moves, it gradually loses pressure on the cleaning rack 301. Under the reset action of the connecting spring 405, the movable seat 404 moves towards the fixed seat 402. During this movement, the movable seat 404 lifts the connecting rod 403, which in turn lifts the cleaning rack 301. As the cleaning rack 301 is lifted, it rotates along the rotating shaft 401 towards the sign 2 until the set driving time of the first motor 101 is reached. The first motor 101 then stops, and the sign 2 stops moving. At this point, the cleaning cloth 302 is in contact with the sign 2. Then, the third motor 303 is started, driving the output shaft to rotate, thus moving the sign 2 towards the mounting end. The soiled cloth cylinder 304 rotates, and during the rotation of the soiled cloth cylinder 304, the cleaning cloth 302 of the cleaning cloth cylinder 305 moves and rolls up. During the movement and rolling up, the cleaning cloth 302 contacts the sign 2 and cleans the sign 2 until the driving time set by the third motor 303 is reached. The cleaning cloth 302 stops cleaning, and the first motor 101 is started by controlling it to rotate in the opposite direction, which drives the sign 2 to reset and move. During the movement of the sign 2, the sign 2 gradually squeezes the cleaning frame 301. During the squeezing process, the cleaning frame 301 rotates along the rotating shaft 401 away from the sign 2 and squeezes the connecting rod 403. The connecting rod 403 drives the movable seat 404 to stretch the connecting spring 405 and move away from the fixed seat 402 until the driving time set by the first motor 101 is reached. The first motor 101 stops, the sign 2 stops moving, and at this time the sign 2 and the cleaning frame 301 are reset, waiting for the next cleaning, avoiding high-altitude cleaning operations. During the use of the gas station eaves sign, when the cleaning cloth 302 reaches its set replacement cycle, the second motor 201 is started. The second motor 201 drives the output end to rotate, which in turn drives the unwinding shaft 203 to rotate, and drives the two unwinding drums 202 to rotate. During the rotation of the two unwinding drums 202, the two unwinding ropes 204 are lowered, which in turn lowers the upper bottom support frame 4, support column 5, and lower bottom support frame 3, and lowers the cleaning frame 301. This continues until the second motor 201 stops after its set driving time, and the cleaning frame 301 stops descending. This process avoids high-altitude operations during replacement. After replacement, the second motor 201 is started again, causing it to rotate in the opposite direction, which in turn resets the cleaning frame 301.
