The lifting plate inside the cleaning box moves up and down through the second reduction motor and the screw mechanism, driving the brush to contact and wipe the surface of the advertising cloth. At the same time, the water pump transports the cleaning liquid in the water tank to the water receiving tank through the curved pipe, and drips evenly onto the brush through the small holes at the bottom of the water receiving tank, ensuring that the brush is wet and evenly cleans the printed advertising cloth. This design not only improves the cleaning effect, but also avoids water waste, achieving the purpose of energy saving and environmental protection.

[0017] 3. By setting up a drying plate with a PTC ceramic heating plate, the advertising cloth can be dried quickly after cleaning. After cleaning, the light provided by the light board can illuminate the advertising cloth, and the PTC ceramic heating plate built into the drying plate can quickly evaporate the residual moisture, ensuring that the advertising cloth is restored to a state suitable for display in a short time. This drying mechanism not only improves the display quality after cleaning, but also extends the service life of the advertising cloth, ultimately achieving the beneficial effect of improving the reliability of the display board and reducing the maintenance frequency.

The rear side of the shell 4 is connected to the cleaning box 2, and the interior of the cleaning box 2 is provided with a lifting plate 24 that can move up and down. A brush 25 is provided on one side of the lifting plate 24. The brush 25 can contact the back of the printed advertising cloth 12 when it is lifted and lowered, and brush it. A water pump 27 is connected to one side of the water tank 10. The water pump 27 can extract water or cleaning liquid from the water tank 10. The water outlet of the water pump 27 is connected to a curved pipe 28. A water receiving trough 22 is provided at the lower part of the curved pipe 28. The water receiving trough 22 is welded to one side of the cleaning box 2. A plurality of small holes are provided at the lower part of the water receiving trough 22, and the water flowing out of the small holes can drip on the brush 25.

[0023] Two first guide rods 16 are rotatably connected to the left side of the shell 4, and two second guide rods 15 are rotatably connected to the right side of the shell 4. The printed advertising cloth 12 is sleeved on the outside of the first guide rods 16 and the second guide rods 15, so that the front and rear parts of the printed advertising cloth 12 are stretched tight and flat.

[0024] A light board 21 and a drying board 20 are provided between the front and rear cloth pieces of the printed advertising cloth 12. A PTC ceramic heating plate is provided inside the drying board 20. The light board 21 is used to illuminate the advertisement at night and can also be used to assist in checking the cleanliness of the billboard.

[0025] The upper part of the waterproof cover 1 is connected with a solar panel 5 , and the solar panel 5 is electrically connected with a storage battery 11 . The electricity collected by the solar panel 5 is stored in the storage battery 11 through a converter.

[0026] A water inlet pipe is disposed on the upper portion of the water tank 10 , a cover 6 is disposed on the upper portion of the water inlet pipe, and a junction box 3 is mounted on the outer shell 4 and the waterproof cover 1 , respectively.

[0027] The upper front part and the lower front part of the shell 4 are respectively welded with protective plates 7 , and the lower part of the shell 4 is welded with a water receiving box 8 , which has a water outlet hole. The upper part of the water receiving box 8 is connected to the inside of the shell 4 .

[0028] The rear side of the cleaning box 2 is connected with a cover plate 13 by bolts, the left and right sides of the inside of the cleaning box 2 are respectively welded with guide rails 14, and the left and right sides of the lifting plate 24 are respectively fixedly connected with sliders, which are slidably connected to the guide rails 14.

[0031] The lower part of the screw rod 26 is connected to the inside of the housing 4 through a rotating shaft. A column 9 is welded to the lower part of the housing 4 to play a supporting role.

[0032] When in use, the first reduction motor 19 is started, and the motor drives the second rotating roller 17 to rotate, thereby moving the printed advertising cloth 12 along a set path. At this time, the front content on the printed advertising cloth 12 is replaced to the back, and the back content is displayed. This process realizes the automatic switching of advertising content, ensuring the freshness and diversity of the displayed information.

[0033] During use, when the printed advertising cloth 12 needs to be cleaned, the second rotating roller 17 is controlled to rotate so that the surface to be cleaned moves to the inside of the cleaning box 2. At this time, the second reduction motor 23 is started, and the lifting plate 24 is driven to move up and down through the screw rod 26, driving the brush 25 to scrub the surface of the printed advertising cloth 12. At the same time, the water pump 27 is started, and the cleaning liquid in the water tank 10 is transported to the water receiving trough 22 through the curved pipe 28, and evenly sprinkled onto the brush 25 through the small holes at the bottom of the water receiving trough 22 to enhance the cleaning effect. The cleaned waste water flows into the water receiving box 8 and is discharged through the water outlet.

[0034] After cleaning is completed, the PTC ceramic heating plate in the drying plate 20 starts to heat up, generating heat to dry the printed advertising cloth 12, while the light board 21 provides lighting to assist in checking the cleaning effect. During the drying process, the heat generated by the PTC ceramic heating plate can quickly evaporate the moisture on the printed advertising cloth 12, ensuring that it can be put into use immediately after drying and maintain a good display state.

[0035] In order to ensure the continuous operation of the equipment and the rational use of energy, the solar panel 5 on the waterproof cover 1 can absorb sunlight and convert it into electrical energy, which is stored in the battery 11 for use at night or in other dark conditions. In addition, the junction box 3 is used to connect the external power supply and control system to facilitate the debugging and maintenance of the equipment.

[0036] In summary, the present invention realizes the efficient operation of the self-cleaning multimedia cultural display board through reasonable mechanism design and intelligent control system, which not only ensures the timely updating of advertising content, but also simplifies the daily maintenance process, greatly improving the practical value and economic benefits of the display board.
