DETAILED DESCRIPTION

[0025] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0026] Reference Figure 1-Figure 6 An internet advertising LED screen includes a rectangular device frame 1, a back plate 2 is fixedly connected to the rear end of the device frame 1, a control box 3 is arranged inside the device frame 1, a mounting frame 4 is fixedly connected to the front end of the control box 3, the mounting frame 4 is located at the front end of the device frame 1, a display screen 5 is installed inside the mounting frame 4, the display screen 5 is composed of a plurality of LED screens, a control unit of the display screen 5 is arranged inside the control box 3, and when the display screen 5 is working, its heat is mainly generated inside the control box 3. The rear end of the control box 3 is spaced apart from the back plate 2 to form a heat dissipation space. The rear end of the control box 3 is fixedly connected to two sets of symmetrically arranged heat dissipation mechanisms, such as Figure 5Each group of heat dissipation mechanisms is composed of two rows of multiple heat dissipation fins 6 that are tilted and evenly arranged. Each heat dissipation fin 6 is tilted downward toward the position between the two groups of heat dissipation mechanisms. The tilt of each heat dissipation fin 6 is consistent in size. The front end of the heat dissipation fin 6 is located in the control box 3, and the rear end of the heat dissipation fin 6 is arranged close to the back plate 2. The material of the heat dissipation fin 6 is existing technology and will not be explained here. The heat dissipation fin 6 can export the heat in the control box 3 to the device frame 1.

[0027] The left and right ends of the device frame 1 are fixedly installed with heat dissipation fans 7, and the inner walls on both sides of the device frame 1 are fixedly installed with a plurality of inclined blowing pipe heads 8, each blowing pipe head 8 has the same inclination as the heat dissipation fins 6 on the same side. An exhaust passage 9 is provided at the lower end of the device frame 1 and between the two groups of heat dissipation mechanisms. The air inlet of the heat dissipation fan 7 is arranged outward, and the air outlet of the heat dissipation fan 7 is connected with the blowing pipe heads 8 on the same side. The heat dissipation fan 7 can blow air into the device frame 1 through the blowing pipe heads 8 on the same side. Through the inclined heat dissipation fins 6 and the exhaust passage 9, the wind blown in from both sides can be blown toward between the two groups of heat dissipation mechanisms along the corresponding heat dissipation fins 6 and flow downward, so as to be discharged through the exhaust passage 9. This method quickly and effectively brings the heat derived from the heat dissipation fins 6 out of the device frame 1, plays an efficient heat dissipation effect, ensures that the temperature in the control box 3 will not overheat, and ensures the normal operation of the display screen 5.

[0028] Four rectangular fixed plates 10 are fixedly connected to the left and right ends of the device frame 1, and a sliding rod 11 is fixedly connected between every two front and rear corresponding fixed plates 10. A movable plate 12 is slidably sleeved on the four sliding rods 11, and the front ends of the four movable plates 12 are fixedly connected to connecting plates 13, and the front ends of the four connecting plates 13 are fixedly connected to the installation frame 4. The arrangement of the sliding rods 11, the movable plates 12 and the connecting plates 13 allows the control box 3 and the installation frame 4 to move longitudinally along the device frame 1. In the initial state, each movable plate 12 is located at the rear end. At this time, each heat dissipation fin 6 on the control box 3 is arranged close to the back plate 2, and the installation frame 4 remains in a state of being in contact with the front end of the device frame 1.

[0029] The upper ends of the two movable plates 12 located above are commonly fixedly connected to a horizontal plate 14, and the horizontal plate 14 is located above the device frame 1. Two vertical plates 15 arranged at intervals on the left and right are fixedly connected to the upper end of the device frame 1 and at the rear side of the movable plate 12. A two-way threaded rod 16 is commonly rotatably connected between the two vertical plates 15. Two movable sleeve blocks 17 arranged at intervals on the left and right are threadedly sleeved on the two-way threaded rod 16. Active connecting rods 18 are rotatably connected between the upper ends of the two movable sleeve blocks 17 and the upper ends of the horizontal plate 14. The two active connecting rods 18 are in an eight-shape when viewed from above, and a first motor 21 that drives the two-way threaded rod 16 to rotate is fixedly installed on one of the vertical plates 15. Specifically, when the first motor 21 drives the bidirectional threaded rod 16 to rotate, the two movable sleeves 17 can be driven to move relative to each other. When the two movable sleeves 17 move closer to each other, the horizontal plate 14 can be pushed forward under the connection of the two movable connecting rods 18, so that the control box 3 and the installation frame 4 can be pushed forward by the corresponding movable plate 12. In this state, it is convenient to install and disassemble the display screen 5. In this state, each heat dissipation fin 6 is away from the back plate 2, so that a certain interval is formed between the heat dissipation fin 6 and the back plate 2, thereby expanding the heat dissipation space. When the two movable sleeves 17 move away from each other, the movable plate 12 can be pulled backward to move the control box 3 and the installation frame 4 to the initial position.

[0030] A movable opening is vertically opened at the rear end of the back plate 2 and between the two groups of heat dissipation mechanisms. A cleaning mechanism is provided on the back plate 2. The cleaning mechanism includes a driving box 19 fixedly connected to the rear end of the back plate 2 and communicated with the movable opening. A threaded rod 20 is rotatably connected between the upper and lower inner walls of the driving box 19. A limit rod is fixedly connected between the upper and lower inner walls of the driving box 19. A lifting plate 22 is jointly sleeved on the threaded rod 20 and the limit rod. The lifting plate 22 is threadedly connected to the threaded rod 20. The lifting plate 22 is slidably connected to the limit rod. A vertical plate 23 is fixedly connected to the lower end of the lifting plate 22. A horizontally arranged electric telescopic rod 24 is fixedly installed on the vertical plate 23. The telescopic end of the electric telescopic rod 24 passes through the movable opening and is fixedly connected to a trapezoidal plate 25 in the control box 3. The electric telescopic rod 24 can drive the trapezoidal plate 25 to move forward and backward. Both sides of the trapezoidal plate 25 are fixedly connected with inclined plates 26, and the two inclined plates 26 have the same inclination as the two groups of heat dissipation mechanisms. Two cleaning rollers 27 are rotatably connected to the two inclined plates 26. The two cleaning rollers 27 located on the same inclined plate 26 correspond to the positions of the two rows of heat dissipation fins 6 on the same side and are arranged in parallel. The positions of the two inclined plates 26 near the trapezoidal plate 25 are fixedly installed with second motors 29, and the output ends of the two second motors 29 are coaxially fixedly connected with drive rods 28. The end of the drive rod 28 away from the second motor 29 is coaxially penetrated through the corresponding two cleaning rollers 27. The second motor 29 can drive the corresponding two cleaning rollers 27 to rotate. A third motor 35 for driving the threaded rod 20 to rotate is fixedly installed on the upper end of the drive box 19. The third motor 35 can drive the threaded rod 20 to rotate, thereby controlling the position height of the lifting plate 22, thereby controlling the position height of each cleaning roller 27.

[0031] During long-term heat dissipation, dust will adhere to the heat dissipation fins 6 due to external air. When dust accumulates to a certain extent, the heat dissipation fins 6 will lose their effective heat dissipation function, and then the normal heat dissipation of the display screen 5 and the control box 3 cannot be guaranteed. At this time, it is only necessary to drive the horizontal plate 14 forward through the first motor 21 to enlarge the heat dissipation space between the control box 3 and the back plate 2. At this time, the corresponding cleaning rollers 27 can be driven to rotate by the two second motors 29. The cleaning rollers 27 can be moved to the designated surface of the heat dissipation fins 6 by the cooperation of the third motor 35 and the electric telescopic rod 24. The dust on the surface of the heat dissipation fins 6 can be removed by the high-speed rotation of the cleaning rollers 27. This method can clean the upper and lower surfaces of some heat dissipation fins 6 to ensure the heat dissipation effect of the heat dissipation fins 6. After cleaning, the cleaning rollers 27 move to the highest position, and the control box 3 moves back and resets.

[0032] A Y-shaped fixing frame 30 is fixedly connected to the upper end of the back plate 2, and a rain shield 31 is fixedly connected to the upper end of the fixing frame 30. The rain shield 31 is located above the device frame 1 and can protect the mechanism below from rain. A water storage tank 32 is fixedly connected to the upper end of the rain shield 31, and a submersible pump is installed in the water storage tank 32. The water outlet of the submersible pump is connected to two connecting pipes 34. Two water spray heads 33 extending into the device frame 1 are fixedly installed at the rear end of the back plate 2. The ends of the two connecting pipes 34 away from the submersible pump are respectively connected to the rear ends of the two water spray heads 33. The water storage tank 32 is filled with water in advance. After the dust cleaning work of the heat dissipation fins 6 is performed, the submersible pump in the water storage tank 32 can make the water spray heads 33 spray water into the device frame 1, so that the dust on the inner wall can be effectively adsorbed by the water mist, so that it gathers at the bottom of the device frame 1 and is smoothly discharged from the exhaust channel 9.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
