Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1-3 shown, the present invention provides a cultural publicity device, including a publicity column body 1. A plurality of connecting rods 14 are fixedly arranged on the upper and lower end faces of the publicity column body 1. The bottom surface of the rain shield 11 is fixedly connected to the top surface of the connecting rod 14 at the top of the publicity column body 1. The top surface of the support plate 12 is fixedly connected to the bottom surface of the connecting rod 14 at the bottom of the publicity column body 1. By providing the connecting rod 14, there is enough space between the connection of the publicity column body 1, the rain shield 11 and the support plate 12 to set up a pulley group 33. The bottom surface of the rain shield 11 is fixedly connected to the top surfaces of two support columns 13. The lower ends of the two support columns 13 respectively penetrate through the left and right ends of the top surface of the support plate 12 and extend a part. A cleaning mechanism 2 for cleaning the surface of the publicity column body 1 and a rotating mechanism 3 for controlling the movement of the cleaning mechanism 2 are provided on the publicity column body 1.

[0029] As Figures 5-7 shown, the cleaning mechanism 2 includes that the middle part of the top surface of the rain shield 11 is fixedly connected to the bottom surface of the water storage tank 28. The tops of two second nozzles 214 are fixedly connected to the bottom surface of the rain shield 11 near the two support columns 13. A plurality of first nozzles 29 are symmetrically arranged on the front and rear of the bottom surface of the rain shield 11. A plurality of limit grooves 210 are symmetrically opened on the left and right sides of the two side surfaces of the publicity column body 1. The surfaces of a plurality of limit support rods 212 are respectively slidably connected to the inner walls of the corresponding limit grooves 210. Springs 211 are sleeved on the surfaces of the plurality of limit support rods 212. One ends of the plurality of springs 211 are respectively fixedly connected to one side surface of the two runner groups 213 close to the publicity column body 1. The runner group 213 is composed of a connecting frame and a plurality of rotating wheels rotatably arranged inside the connecting frame. The other ends of the plurality of springs 211 are respectively fixedly connected to the left and right side surfaces of the publicity column body 1. By providing the spring 211, the sponge wiper 26 can squeeze out sewage when passing through the surface of the runner group 213 and will not block the subsequent movement of the rubber squeegee 27. The tops of the first nozzles 29 and the second nozzles 214 are respectively connected to the water storage tank 28 through the pipelines inside the rain shield 11. A water pump is built in the water storage tank 28, and the water in the water storage tank 28 can be used to wash the glass surface of the publicity column body 1 through the first nozzles 29, and the runner group 213 can be washed through the second nozzles 214;

[0030] The backs of two groups of connecting blocks 21 are respectively fixedly connected to the surfaces of two driving belts 333. Two groups of limiting holes 22 are respectively formed in the surfaces of the two groups of connecting blocks 21. Two groups of limiting rods 23 are slidably arranged on the inner sides of the two groups of limiting holes 22. The fronts of two cleaning plates 25 are respectively fixedly connected to the backs of the two groups of limiting rods 23. A sponge scrubber 26 is fixedly arranged on the back of the left cleaning plate 25, and a rubber squeegee strip 27 is fixedly arranged on the back of the right cleaning plate 25. Limiting springs 24 are sleeved on the surfaces of the two groups of limiting rods 23. The front ends of the limiting springs 24 are fixedly connected to one side surface of the connecting block 21 close to the cleaning plate 25, and the rear ends of the limiting springs 24 are fixedly connected to one side surface of the cleaning plate 25 close to the connecting block 21. By arranging the limiting springs 24, the sponge scrubber 26 and the rubber squeegee strip 27 fixedly arranged on the back of the cleaning plate 25 can be in close contact with the glass surface of the publicity column body 1, enabling the sponge scrubber 26 to clean more thoroughly and the rubber squeegee strip 27 to scrape off the water on the glass surface of the publicity column body 1 cleanly.

[0031] As Figures 1-4 shown, the rotating mechanism 3 includes a motor 31 fixedly arranged at the bottom of the support plate 12. The output end of the motor 31 penetrates through the support plate 12 and is fixedly connected to the bottom end of a rotating rod 32. Two driving pulleys 331 are respectively rotatably arranged on the upper and lower end surfaces of the publicity column body 1 close to one side of the motor 31. The upper and lower end surfaces of the rotating rod 32 are respectively fixedly sleeved with the two driving pulleys 331. The rotating rod 32 penetrates through one side of the bottom surface of the publicity column body 1 close to the motor 31 and is rotatably connected to the publicity column body 1. Two driven pulleys 332 are respectively rotatably arranged on the upper and lower end surfaces of the publicity column body 1 on the side far from the motor 31. The driving pulley 331 and the driven pulley 332 are in transmission connection through a driving belt 333. By arranging the pulley set 33, the cleaning mechanism 2 can move back and forth on the front and back sides of the publicity column body 1, enabling both sides to be cleaned and saving materials.

[0032] The principle and process of the present utility model:

[0033] When this device is in use, when there is dust or water stains on the glass surface of the bulletin board body 1, the water pump built in the water storage tank 28 is turned on, and the water inside the water storage tank 28 is used to wash the front and back sides of the bulletin board body 1 through the first nozzle 29. Then the motor 31 is turned on. The output end of the motor 31 can drive the rotating rod 32 to rotate. When the rotating rod 32 rotates, it will drive the two driving pulleys 331 to rotate synchronously. Through the transmission of the transmission belt 333, it further drives the two driven pulleys 332 to rotate. At the same time, the two groups of connecting blocks 21 will also move along with the transmission belt 333. When the two groups of connecting blocks 21 move, they will drive the cleaning plate 25, the sponge wipe 26 and the rubber squeegee 27 to move. When the sponge wipe 26 first contacts the glass surface of the bulletin board body 1, the connecting block 21 tightly presses the sponge wipe 26 on the back of the cleaning plate 25 against the glass surface of the bulletin board body 1 through the elasticity of the limit spring 24, so that the sponge wipe 26 can better remove the stains on the glass surface. Then, the rubber squeegee 27 also tightly adheres to the glass surface due to the limit spring 24 to better remove the remaining water on the glass surface. When the front side of the bulletin board body 1 is cleaned, during the continuous movement along the transmission belt 333, the limit spring 24 first returns to its original length until the rotating wheel surface of the rotating wheel group 213 contacts the surface of the sponge wipe 26, and the spring 211 and the limit spring 24 are compressed. The elastic forces of the spring 211 and the limit spring 24 will squeeze out the sewage inside the sponge wipe 26, so that the sponge wipe 26 maintains a relatively clean state that can absorb water. After the extrusion, the motor 31 is paused, and the second nozzle 214 is turned on to wash the surface of the rotating wheel group 213, so that the surface of the rotating wheel group 213 is washed clean, so that the rubber squeegee 27 will not stick to stains when passing through later, effectively avoiding scratches on the glass surface of the bulletin board body 1 caused by the rubber squeegee 27 sticking to dust and stains. Then the motor 31 is turned on to continue rotating to clean the other side of the bulletin board body 1. After the cleaning is completed, the rotating wheel group 213 is washed again.
