Description

Technical Field

[0001] This invention relates to the field of advertising machine technology, specifically a self-cleaning LED light pole screen advertising machine and method. Background Technology

[0002] A light pole advertising display is a new generation of intelligent device installed on a light pole. It forms a complete advertising broadcasting and control system through terminal software control, network information transmission and multimedia terminal display, and carries out advertising through multimedia materials such as pictures, text, videos and plug-ins.

[0003] In the application of LED pole advertising displays, dust inevitably accumulates on the screen. Existing technology CN112058802A proposes an LED display screen with a self-cleaning function, including a mounting base. The display screen body is mounted on top of the mounting base, and a fixing plate is mounted on top of the display screen body. This display screen uses a rotating cleaning cylinder and water spraying to clean the screen.

[0004] However, this display screen still has certain defects in its use. When a large amount of dust adheres to the surface of the screen, the method of spraying water and using a cleaning cylinder will turn the dust into muddy water. As the water is sprayed and the cleaning brush moves, it can play a certain cleaning role. However, since the roller brush itself is covered with muddy water, it will leave traces of the roller brush movement on the screen after cleaning, making the cleaning effect less than ideal. At the same time, the display screen cannot clean the cleaning cylinder, so after a period of use, a large amount of dust and sludge will stick to the cleaning cylinder, which will lead to poor subsequent cleaning results. In order to address the above problems, we provide a self-cleaning LED light pole screen advertising machine and method to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a self-cleaning LED light pole screen advertising machine and method to solve the problems of watermarks on the surface of the advertising machine after cleaning and the easy contamination of the cleaning cylinder by dirt in the prior art.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. During operation, this invention uses a lifting assembly to drive the lifting housing to move up and down. This movement of the lifting housing simultaneously drives the cleaning brush to move up and down as well. The cleaning brush, in turn, moves rapidly back and forth left and right. This, combined with the sprayed cleaning fluid, cleans the surface of the light pole screen. The lifting housing is also equipped with a rubber scraper. When the lifting housing moves upward, the rubber scraper is raised and does not contact the surface of the light pole screen. When the lifting housing descends, the rubber scraper adheres to the surface of the light pole screen to scrape away the water marks left by the cleaning brush, thus avoiding the situation in existing technologies where traces remain after screen cleaning.

[0025] 2. The present invention has a cleaning component that can clean the cleaning brush after the cleaning brush has cleaned the main body of the light pole screen, removing the dirt adhering to the cleaning brush, thereby ensuring the cleanliness of the cleaning brush and avoiding the problem of unsatisfactory cleaning when cleaning the main body of the light pole screen after the cleaning brush is contaminated by dirt.

[0026] 3. This invention, through the setting of an upper and lower top rod, can automatically change the state of the rubber scraper during use. When the flipping rod moves upward to the top, the upper top rod will press the reversing rod downward to flip it. After flipping, the state is maintained under the action of the tension spring, so that the rubber scraper is close to the surface of the light pole screen body, so that the lifting sleeve can scrape away water marks when it moves downward. When the lifting sleeve moves to the bottom, the lower top rod will push the reversing rod upward, so that the rubber scraper returns to the state of not contacting the light pole screen body. This allows the rubber scraper to automatically switch states during use, thereby improving the cleaning effect of the light pole screen body. Attached Figure Description

[0040] The lower end of the light pole screen body 1 is provided with a bottom box 41, and a bottom box 3 is fixedly connected to the lower end of the bottom box 41. The lower end face of the bottom box 3 is provided with a drain outlet 4 for drainage. A lifting sleeve 2 is slidably connected to the light pole screen body 1. A lifting assembly for driving the lifting sleeve 2 to rise and fall is provided in the middle of the back of the light pole screen body 1. The lifting assembly includes a threaded sleeve 32, which is fixedly connected to the middle of the lifting sleeve 2. A threaded rod 12 is rotatably connected to the middle of the back of the light pole screen body 1. The threaded rod 12 is threadedly connected to the threaded sleeve 32. A bottom shaft 15 is rotatably connected to the bottom of the light pole screen body 1. A first bevel gear 13 is fixedly connected to the lower end of the shaft. A second bevel gear 14 is fixedly connected to the end of the bottom shaft 15 near the threaded rod 12. The second bevel gear 14 and the first bevel gear 13 mesh. A first gear 16 is fixedly connected to the end of the bottom shaft 15 away from the second bevel gear 14. During operation, the first gear 16 drives the bottom shaft 15 to rotate. The rotation of the bottom shaft 15 drives the second bevel gear 14 to rotate. The rotation of the second bevel gear 14 drives the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 drives the threaded rod 12 to rotate. The rotation of the threaded rod 12, in conjunction with the threaded sleeve 32, enables the lifting and lowering of the lifting housing 2.

[0041] A sliding crossbar 38 is fixedly connected to one side of the lifting housing 2. A cleaning brush 36 is slidably connected to the sliding crossbar 38. The cleaning brush 36 has several water spray nozzles 40 on the side near the bristles, and a water inlet 34 on the side away from the bristles. The liquid storage tank 10 is equipped with a liquid supply assembly for supplying liquid into the water inlet 34. The liquid supply assembly includes a water pump 17, which is fixedly connected to one side of the liquid storage tank 10. The input end of the water pump 17 extends to the bottom of the liquid storage tank 10, and the output end of the water pump 17 is connected to a hose 11. The end of the hose 11 away from the water pump 17 is connected to the water inlet 34. Cleaning liquid can be added to the liquid storage tank 10 periodically through the liquid filling port 9. During operation, the water pump 17 draws the cleaning liquid from the mounting arm 5 into the hose 11, and then delivers it to the water inlet 34 through the hose 11.

[0042] The lifting housing 2 is equipped with a vibration component for driving the cleaning brush 36 to vibrate. The vibration component includes a rotating shaft 18, which is rotatably connected inside the lifting housing 2 below the cleaning brush 36. Both ends of the rotating shaft 18 are fixedly connected to swing wheels 35. Both sides of the lower end face of the cleaning brush 36 are fixedly connected to mating rollers 37 that cooperate with the swing wheels 35. One end of the rotating shaft 18 is fixedly connected to a second gear 19 extending out of the lifting housing 2. The lifting housing 2 is also equipped with a rotating component for driving the rotating shaft 18 to rotate. During operation, the rotating component drives the second gear 19 to rotate, which in turn drives the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 drives the swing wheels 35 to rotate, and the rotation of the swing wheels 35, in cooperation with the mating rollers 37, drives the cleaning brush 36 to reciprocate, thereby cleaning the main body 1 of the light pole screen.

[0043] The rotating assembly includes a fixed rack 6, which is fixedly connected to one side of the main body 1 of the light pole screen. A large gear 22 is rotatably connected to one side of the lifting sleeve 2. A third gear 23 is fixedly connected to the large gear 22. The third gear 23 meshes with the fixed rack 6, and the large gear 22 meshes with the second gear 19. During operation, the third gear 23 and the fixed rack 6 rotate together. The rotation of the third gear 23 drives the large gear 22 to rotate, and the large gear 22 drives the second gear 19 to rotate. The large gear 22 driving the second gear 19 will have an acceleration effect, causing the rotating shaft 18 to rotate rapidly.

[0044] The lifting housing 2 is also equipped with a scraping assembly for scraping the surface of the light pole screen body 1. The scraping assembly includes a flipping rod 33, which is rotatably connected to the lifting housing 2 above the cleaning brush 36. A rubber scraper 39 is fixedly connected to the flipping rod 33. A limit rod 21 is fixedly connected to one end of the flipping rod 33, which protrudes from the lifting housing 2. A tension spring 20 is provided at the end of the limit rod 21. The lower end of the tension spring 20 is fixedly connected to the lifting housing 2 near the second gear 19. A reversing rod 24 is fixedly connected to the other end of the flipping rod 33. Two limit blocks 25 for limiting the reversing rod 24 are provided on the other side of the lifting housing 2. A lower push rod 2 is provided on the bottom box 3 below the reversing rod 24 for pushing the reversing rod 24. 6. The main body 1 of the light pole screen is also provided with an upper push rod 7 for pushing the reversing rod 24 above it. With the upper push rod 7 and the lower push rod 26, the state of the rubber scraper 39 can be automatically changed during use. When the flipping rod 33 moves upward to the top, the upper push rod 7 will push the reversing rod 24 downward to flip it. After flipping, the state is maintained under the action of the tension spring 20, so that the rubber scraper 39 is close to the surface of the main body 1 of the light pole screen. This allows the lifting sleeve 2 to scrape away water marks when it moves downward. When the lifting sleeve 2 moves to the bottom, the lower push rod 26 will push the reversing rod 24 upward, so that the rubber scraper 39 returns to the state of not contacting the main body 1 of the light pole screen. This allows the rubber scraper 39 to automatically switch states during use, thereby improving the cleaning effect of the main body 1 of the light pole screen.

[0045] The bottom box 41 is equipped with a cleaning assembly for cleaning the bristles on the cleaning brush 36. The cleaning assembly includes a limiting slide rod 42, which is fixedly connected to the upper end of the bottom box 41. A reciprocating screw 43 is rotatably connected to the lower part of the bottom box 41. A sliding seat 45 is threaded onto the reciprocating screw 43, and the sliding seat 45 is slidably connected to the limiting slide rod 42. A fourth gear 31 is fixedly connected to one end of the reciprocating screw 43, extending out of the bottom box 41. Two cleaning dials 47 are rotatably connected inside the sliding seat 45. The bottom box 41 is equipped with a transmission assembly for driving the cleaning dials 47 to rotate. The transmission assembly includes a bottom rack 44. The cleaning wheel 47 is fixedly connected to the upper end of the bottom box 41. A fifth gear 46 is installed on the connecting shaft head at the upper end of the cleaning wheel 47. The fifth gear 46 meshes with the bottom rack 44. During operation, the fourth gear 31 rotates, driving the reciprocating screw 43 to rotate. The rotation of the reciprocating screw 43 drives the sliding seat 45 to move back and forth. While the sliding seat 45 is moving, the fifth gear 46 meshes with the bottom rack 44, causing the fifth gear 46 to rotate. The rotation of the fifth gear 46 can drive the cleaning wheel 47 to rotate. The rotation of the cleaning wheel 47 can move the bristles on the cleaning brush 36. At the same time, the cleaning liquid sprayed out comes into contact with the bristles under the action of the rotation of the cleaning wheel 47 to rinse them, thereby cleaning the bristles of the cleaning brush 36.

[0046] One end of the base box 3 is provided with a drive component for driving the lifting and cleaning components. The drive component includes a fixed frame 28, which is fixedly connected to the base box 3 near the fourth gear 31 and the first gear 16. A drive motor 27 is slidably connected inside the fixed frame 28. A motor gear 30 is installed at the output end of the drive motor 27. The motor gear 30 is located between the fourth gear 31 and the first gear 16. The lower end of the fixed frame 28 is provided with an electric cylinder 29 for adjusting the position of the drive motor 27. During operation, the electric cylinder 29 drives the drive motor 27 to move, causing the motor gear 30 to drive the first gear 16 to rotate. The rotation of the first gear 16 drives the corresponding transmission components, thereby driving the lifting housing 2 to move up and down to clean the surface of the light pole screen body 1. When the lifting housing 2 moves to the bottom, the electric cylinder 29 drives the drive motor 27 to move, causing the motor gear 30 to mesh with the fourth gear 31, thereby driving the fourth gear 31 to rotate.

[0047] The working principle of this invention is as follows: When the main body 1 of the light pole screen needs to be cleaned, the electric cylinder 29 drives the drive motor 27 to move, causing the motor gear 30 to drive the first gear 16 to rotate. The first gear 16 drives the bottom shaft 15 to rotate, the bottom shaft 15 rotates, driving the second bevel gear 14 to rotate, the second bevel gear 14 rotates, driving the first bevel gear 13 to rotate, and the first bevel gear 13 rotates, driving the threaded rod 12 to rotate. The rotation of the threaded rod 12, in conjunction with the threaded sleeve 32, enables the lifting housing 2 to rise. While the system is in motion, the water pump 17 draws out the cleaning fluid and delivers it to the hose 11, which is then sprayed out through the nozzle 40. Simultaneously, the third gear 23 rotates in conjunction with the fixed rack 6. This rotation of the third gear 23 drives the large gear 22 to rotate, which in turn drives the second gear 19 to rotate. The rotation of the second gear 19 drives the rotating shaft 18 to rotate, which in turn drives the oscillating wheel 35 to rotate. The oscillating wheel 35, in conjunction with the cooperating roller 37, drives the cleaning brush 36 to reciprocate. Simultaneously, the cleaning fluid helps to clean the lamp post. The cleaning of the screen body 1 is carried out simultaneously. The lifting housing 2 is also equipped with a rubber scraper 39. When the lifting housing 2 moves upward, the rubber scraper 39 is raised and does not contact the surface of the light pole screen body 1. When the lifting housing 2 descends, the rubber scraper 39 adheres to the surface of the light pole screen body 1 to scrape away the water marks left by the cleaning brush 36. After the lifting housing 2 moves up and down once, it descends to the bottom of the light pole screen body 1. Then, the electric cylinder 29 drives the drive motor 27 to move, causing the motor gear 30 to mesh with the fourth gear 31, thereby driving the fourth gear 31. The fourth gear 31 rotates, driving the reciprocating screw 43 to rotate. The reciprocating screw 43 rotates, driving the sliding seat 45 to move back and forth. While the sliding seat 45 is moving, the fifth gear 46 meshes with the bottom rack 44, causing the fifth gear 46 to rotate. The rotation of the fifth gear 46 drives the cleaning wheel 47 to rotate. The rotation of the cleaning wheel 47 can move the bristles on the cleaning brush 36. At the same time, the cleaning liquid sprayed out comes into contact with the bristles under the action of the rotation of the cleaning wheel 47, thus cleaning the bristles of the cleaning brush 36.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.

9. A method of using the self-cleaning LED light pole screen advertising machine according to any one of claims 1-8, characterized in that, Includes the following steps; Step 1: When it is necessary to clean the main body (1) of the light pole screen, the electric cylinder (29) drives the drive motor (27) to move, so that the motor gear (30) drives the first gear (16) to rotate. The first gear (16) drives the bottom shaft (15) to rotate. The rotation of the bottom shaft (15) drives the second bevel gear (14) to rotate. The rotation of the second bevel gear (14) drives the first bevel gear (13) to rotate. The rotation of the first bevel gear (13) drives the threaded rod (12) to rotate. The rotation of the threaded rod (12) and its cooperation with the threaded sleeve (32) can realize the lifting of the lifting sleeve (2). At the same time as the lifting sleeve (2) moves upward, the water pump... (17) The cleaning liquid is drawn out and sent to the hose (11), and then sprayed out through the nozzle (40). At the same time, the third gear (23) rotates in conjunction with the fixed rack (6). The rotation of the third gear (23) drives the large gear (22) to rotate. The large gear (22) drives the second gear (19) to rotate. The rotation of the second gear (19) can drive the rotating shaft (18) to rotate. The rotation of the rotating shaft (18) can drive the swing wheel (35) to rotate. The rotation of the swing wheel (35) and the cooperation roller (37) drive the cleaning brush (36) to reciprocate. At the same time, the cleaning liquid can clean the main body (1) of the light pole screen. Step 2: At the same time, the lifting sleeve (2) is also equipped with a rubber scraper (39). When the lifting sleeve (2) moves upward, the rubber scraper (39) is lifted and does not contact the surface of the light pole screen body (1). When the lifting sleeve (2) descends, the rubber scraper (39) adheres to the surface of the light pole screen body (1) to scrape the water marks left by the cleaning brush (36). After the lifting sleeve (2) moves up and down once, the lifting sleeve (2) descends to the bottom of the light pole screen body (1). Step 3: Then the electric cylinder (29) drives the drive motor (27) to move, so that the motor gear (30) meshes with the fourth gear (31), thereby driving the fourth gear (31) to rotate. The rotation of the fourth gear (31) drives the reciprocating screw (43) to rotate. The rotation of the reciprocating screw (43) drives the sliding seat (45) to move back and forth. While the sliding seat (45) is moving, the fifth gear (46) meshes with the bottom rack (44), causing the fifth gear (46) to rotate. The rotation of the fifth gear (46) can drive the cleaning wheel (47) to rotate. The rotation of the cleaning wheel (47) can move the bristles on the cleaning brush (36). At the same time, the cleaning liquid sprayed out comes into contact with the bristles under the action of the rotation of the cleaning wheel (47) to rinse, thereby cleaning the bristles of the cleaning brush (36).
