under normal conditions, the connecting rod assembly is in a contracted state, so that the rotary column 6 and the flexible layer 7 are contracted above the display screen 2 instead of protruding out of the surface of the display screen 2, the display screen is more attractive, and during raining, as the surface of the display screen 2 is fully covered with rainwater, the flexible layer 7 is helpful for cleaning the display screen 2, so that the cleaning effect of the display screen 2 is best during raining, and the rainwater enters the interior of the piston tube 8 through the grooves 14, the water-swelling strip 11 swells and stretches after absorbing water, the piston plate 10 and the piston rod 9 are pushed to slide outwards, so that the connecting rod assembly stretches, the rotary column 6 and the flexible layer 7 protrude out of the surface of the display screen 2, meanwhile, the conducting sheet 12 is contacted with the conducting ring 13, the controller controls the electric sliding block 4 to start, the electric sliding block 4 drives the rotary column 6 to move up and down, so that the flexible layer 7 rolls on the surface of the display screen 2 and cleans dirt, the rotary column 6 and the flexible layer 7 can stretch out automatically during raining, the cleaning efficiency of the display screen 2 is improved by utilizing rainwater, and the intelligent degree of the device is further improved; by arranging the elastic piece 15, the elastic piece 15 can be extruded and contracted when the conducting strip 12 impacts the conducting ring 13 in the process that the water-swellable strip 11 pushes the piston plate 10 to slide in the piston tube 8, so that a certain buffer effect can be achieved, the problem that the conducting strip 12 and the conducting ring 13 are damaged due to hard impact is avoided, and the service life of the device is prolonged; after more dust enters the gap between the rotary column 6 and the mounting ring 5, the rotary column 6 can not rotate, and further the flexible layer 7 and the display screen 2 are converted into sliding friction, the display screen 2 and the flexible layer 7 are easy to damage after long-term operation, at the moment, when the elastic piece 15 is contracted, compressed air in the elastic piece is filled into the air ring 16 through a pipeline and is sprayed out towards the inner side of the mounting ring 5 through a plurality of inclined holes 17, so that dust between the rotary column 6 and the mounting ring 5 is cleaned, and the problem that the rotary column 6 cannot rotate due to excessive dust is avoided; by arranging the blocking block 18, when air enters the inclined hole 17 through the air ring 16, the blocking block 18 is pushed to slide in the inclined hole 17, and then the blocking block 18 guides out the inclined hole 17 and impacts the rotating column 6, so that the rotating column 6 generates tiny vibration to promote loosening of dust between the rotating column 6 and the mounting ring 5, and at the moment, the air is sprayed out of the inclined hole 17 again, so that the air flow is convenient for taking away the loosened dust, and the cleaning efficiency of the dust is improved; when the electric sliding block 4 drives the rotary column 6 and the flexible layer 7 to move below the display screen 2, the rotary column 6 and the flexible layer 7 can enter the interior of the grid plate 22 of the water squeezing groove 20, and then the rotary column 6 and the grid plate 22 squeeze the flexible layer 7 to squeeze out sewage and impurities in the flexible layer 7, so that the purpose of automatically cleaning the flexible layer 7 is achieved, the problem of secondary pollution to the display screen 2 after the flexible layer 7 is dirtied is avoided, and the squeezed sewage flows out of the water squeezing groove 20 through the through groove 21 after passing through the grid plate 22; after the rotary column 6 and the flexible layer 7 enter the grid plate 22, the rotary column 6 continuously moves downwards and extrudes the main elastic block 24 through the grid plate 22 and the base 23, so that air in the main elastic block 24 enters the auxiliary elastic block 25 through the guide pipe 27, the auxiliary elastic block 25 is promoted to expand and stretch, the movable block 26 extrudes and deforms the grid plate 22 from two sides to the middle, two side walls of the grid plate 22 are bent towards the top of the flexible layer 7, the top of the flexible layer 7 is extruded, all parts of the flexible layer 7 can be fully extruded, and the extrusion efficiency of sewage and impurities in the flexible layer 7 is improved; when the water-swellable tape 11 is gradually dried and contracted, the piston plate 10 is pulled to slide and reset, the elastic piece 15 is further swelled and reset, negative pressure is generated in the elastic piece, the plugging block 18 returns to the inside of the inclined hole 17 under the tension of the elastic rope I19, at the moment, the negative pressure enables the plugging cap 29 to be separated from the surface of the plugging block 18, the elastic rope II 30 stretches, the through hole 28 is in an open state, external air can be re-inhaled into the elastic piece 15 through the through hole 28, and the problem that the elastic piece 15 is difficult to suck after the plugging block 18 returns to the inclined hole 17 is avoided, so that blowing-up work can be circularly performed.
