First guide grooves 12 are provided on both sides of the front of the main screen 2, and a lifting frame 13 with a hollow interior is slidably connected to the first guide groove 12. First nozzles 14 are evenly arranged on the lower side of the lifting frame 13, and a first scraper 15 is arranged on the lower side of the lifting frame 13. First electric push rods 16 are arranged on both sides of the front of the rain shield 3, and the output end of the first electric push rod 16 is connected to both sides of the upper part of the lifting frame 13, and auxiliary cleaning components connected to the expansion components are plugged into both sides of the lifting frame 13.

[0033] Trash cans 17 are arranged on both sides of the publicity column body 1 , and both sides of the trash cans 17 are connected to both sides of the publicity column body 1 through bolts.

[0034] The expansion component includes an expansion board 18 plugged into one side of the upper part of the publicity column body 1, an expansion screen 19 is embedded in the front side of the expansion board 18, a strip limit block 20 is connected to one side of the expansion board 18, and a connecting rod 21 is arranged on the upper side of the strip limit block 20.

[0035] The upper side of the connecting rod 21 is connected with a sliding plate 22 , and slots are provided on both sides of the rain shelter 3 , and the lower side of the sliding plate 22 is connected with the upper side of the connecting rod 21 .

[0036] The auxiliary cleaning assembly includes a rectangular groove 23 opened at the rear side of the lifting frame 13, a moving frame 24 is arranged inside the rectangular groove 23, a second electric push rod 25 is arranged at the front side of the moving frame 24, and the second electric push rod 25 passes through the moving frame 24 and is connected to the transmission frame 26.

[0037] The rear side of the transmission frame 26 is connected to a second scraper 27, and a second nozzle 28 is provided at the lower side of the second scraper 27. The interior of the mobile frame 24 is also hollow, and one side of the upper part of the mobile frame 24 is connected to the elastic three-way pipe 11. A guide slot 29 is provided on the inner side of the strip limit block 20, and one side of the mobile frame 24 is slidably connected to the guide slot 29. The mobile frame 24 sprays out through the telescopic tube and the second nozzle. A groove corresponding to the output end of the second electric push rod 25 is provided on the inner side of the lifting frame 13.

[0038] It should be noted that, during the educational publicity process, the main screen 2 can be used to perform a variety of educational display operations, and the speakers 31 on both sides of the main screen 2 can be used to increase the fun of the publicity process; during the display and publicity process, once people gather around the main body 1 of the publicity column, the two-way electric push rod 7 located inside the assembly bin 5 will operate, and cooperate with the connecting block 8 to simultaneously pull out the expansion board 18 from both sides of the publicity column main body 1, and make the expansion screen 19 embedded in the front side of the expansion board 18 completely exposed. At this time, the expansion screen 19 is running, and the educational publicity content can also be displayed. At this time, the display area of ​​the actual publicity content of the entire publicity column main body 1 is increased, thereby ensuring that people around the publicity column main body 1 can see the publicity content more clearly, thereby increasing the publicity effect. At the same time, the sliding plate 22 will also be pulled out from the inside of the rainproof shed. After the expansion screen 19 is pulled out, the expansion screen 19 can be protected from rain by the sliding plate 22.

[0039] Since the propaganda column body 1 is often placed outdoors for a long time, a large amount of dust and stains will accumulate on the surface of the propaganda column, affecting the propaganda effect. When the expansion board 18 is pulled out from both sides of the propaganda column body 1, the movable frame 24 will be pulled out from the inside of the lifting frame 13. When it is necessary to clean the surface of the main screen 2 and the expansion screen 19, the second electric push rod 25 is operated, and the second scraper 27 can be pushed to be close to the expansion screen 19 through the transmission frame 26, and the second nozzle 28 is close to the surface of the expansion screen 19. In this case, solenoid valves are provided on both sides of the elastic three-way pipe 11. At this time, the solenoid valve is opened, and the delivery pump 10 is operated, which can draw clean water from the water tank 9 and deliver it to the internal hollow lifting frame 13 and the movable frame 13 through the elastic three-way pipe 11. The cleaning water is evenly sprayed on the surface of the main screen 2 and the extended screen 19 by the first nozzle 14 and the second nozzle 28 inside the frame 24; then, the first electric push rod 16 runs, and at the same time drives the lifting frame 13 and the mobile frame 24 to descend, and cooperates with the first scraper 15 and the second scraper 27 to clean the surface of the main screen 2 and the extended screen 19, and the generated sewage will be collected by the first sewage collection tank 30 and the second sewage collection tank 34, wherein the first guide groove 12 can increase the stability of the lifting frame 13 during the lifting process, and the guide slide groove 29 can increase the stability of the lifting frame 24 during the lifting process, and the guide slide groove 29 is a T-shaped groove as a whole, and the guide slide groove 29 can ensure that the mobile frame 24 will not fall off while sliding in the vertical and horizontal directions.

[0040] When the billboard is in a retracted state, only the main screen 2 of the billboard body 1 is exposed to the outside world. At this time, the movable frame 24 is retracted into the lifting frame 13, and the second electric push rod 25 is in a retracted state, which will cause the second nozzle 28 and the second scraper 27 to retract into the lifting frame 13. At the same time, the solenoid valve is closed. When only the main screen 2 needs to be cleaned, the delivery pump 10 will only deliver water to the inside of the lifting frame 13 and spray it out through the first nozzle 14. The cleaning operation will not continue after the extended screen 19 is retracted into the billboard body 1. In the present technical solution, the elastic three-way pipe 11 is a telescopic pipe with three branches equipped with corrugated pipe sections. Therefore, during the movement of the movable frame 24 and the lifting frame 13, the delivery pump 10 will always be connected with the movable frame 24 and the lifting frame 13 to ensure the cleaning effect.

[0041] The lower side of the bulletin board body 1 is connected with a trash can 17 by bolts, which can prevent people around from throwing trash near the bulletin board body 1 and affecting the experience of people around. In this technical solution, the photovoltaic panel 4 cooperates with the battery device 6 to convert solar energy into electrical energy, wherein the battery device 6 mainly includes a controller, a battery pack and an inverter. When the device is running, the battery can be converted into the alternating current required by the electrical components in this technical solution through the inverter, thereby ensuring the normal operation of the device. The above technology is well known to people in this field and will not be described in detail.

[0042] A first sewage collecting tank 30 is provided at the lower side of the main screen 2 to collect sewage generated by cleaning the main screen 2. Speakers 31 are provided on both sides of the main screen 2 to increase the educational publicity effect.

[0043] A limiting groove 32 is provided at the lower side of the slot, and the lower side of the sliding plate 22 is slidably connected to the limiting groove 32 , which can increase the overall stability of the sliding plate 22 .

[0044] The first scraper 15 and the second scraper 27 are both L-shaped, and the first scraper 15 and the second scraper 27 are made of rubber material as a whole, which can ensure that the main screen 2 and the extended screen 19 are cleaned while preventing scratches on the surface.

[0045] The lifting frame 13 is provided with second guide grooves 33 on both upper and lower sides, and the moving frame 24 is slidably connected to the second guide grooves 33 on both upper and lower sides, so as to increase the stability of the horizontal movement of the moving frame 24 .

[0046] The rain shelter 3 is tilted as a whole, and the tilt angle of the sliding plate 22 matches the tilt angle of the rain shelter 3, so that rainwater can be easily retained.

[0047] The lower sides of the first nozzle 14 and the second nozzle 28 are both inclined, so that the water flows sprayed from the first nozzle 14 and the second nozzle 28 can be sprayed obliquely on the surface of the main screen 2 and the extended screen 19 to prevent splashing when spraying water.

[0048] A second sewage collecting tank 34 is provided at the lower side of the expansion plate 18 to collect sewage generated by cleaning the expansion screen 19 .
