Technical Field

[0001] The invention relates to the technical field of outdoor media display, and in particular to an outdoor portable display screen. Background Art

[0002] Outdoor display screens are large electronic screens installed outdoors, widely used in advertising, information release, public services and other fields. They usually have a large display area, which can attract the attention of audiences from a distance and ensure the effectiveness of information transmission. Large-area display screens not only increase visual impact, but also display more content or higher-resolution images. They are suitable for crowded places such as city squares, commercial blocks, and stadiums, providing audiences with a rich information experience.

[0003] Although large outdoor display screens in the prior art are multiple display screens spliced ​​together, most of the multiple display screens are directly fixed together. When the outdoor display screen encounters strong winds or even typhoon weather, its wind-exposed area is large, and the strong wind may have a huge impact on its structure, causing damage to the fixing brackets and connecting parts of the display screen, and may even cause safety hazards such as the screen falling off or overall collapse. This not only poses a potential threat to pedestrians and property around it, but also causes damage to the equipment itself and high maintenance costs. In addition, strong wind weather may cause the screen image to shake, and the connecting cables to be damaged or broken, seriously affecting the display effect and the normal operation of the equipment, making it impossible to avoid risks in an emergency.

It can not only effectively remove dust, dirt and other pollutants, and prevent the brightness and clarity of the display screen from being affected by dust accumulation, but also reduce the frequency of manual cleaning and reduce maintenance costs. There is no need for manual climbing to a large outdoor display screen at a high height, thus preventing the occurrence of safety accidents.

[0019] 3. The present invention is provided with a photoelectric controller at the bottom of the side of the entire installation frame, and a blocking block is provided on the cleaning component. Only when the entire cleaning component moves down to the bottom of the side of the installation frame, the entire common flip component can drive multiple display screens to flip. The photoelectric controller and the blocking block constitute a safety locking structure for the entire cleaning component to prevent the common flip component from accidentally driving multiple display screens to flip and collide with the cleaning component, causing damage to the cleaning component.

[0020] 4. The core component of the cleaning assembly of the present invention is a cleaning tube, and cleaning holes are equidistantly arranged on the side of the cleaning tube. In addition, a dredging component is arranged inside the bottom support box, and the dredging component can dredge the cleaning holes. A flipping and resetting component is arranged at one end of the cleaning tube. The flipping and resetting component can place multiple groups of cleaning holes at a certain non-ninety-degree inclination angle with the display screen when the cleaning assembly is working, so that the cleaning holes can flush and gather dust in one direction of the display screen, and the dust and dirt are concentrated in one direction, avoiding repeated cleaning and improving the cleaning efficiency. The flipping and resetting component can drive the multiple groups of cleaning holes to be in a horizontal position again when the entire cleaning assembly returns to the initial position, so that the dredging component can be inserted into the cleaning hole for convenience.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Reference Figure 1-13 A portable outdoor display screen includes a mounting frame 1, a bottom support box 12, and a display panel 23. A rain discharge slope 4 is provided at the bottom of the inner wall of the mounting frame 1. The bottom support box 12 is fixedly provided at the bottom of the mounting frame 1. The bottom support box 12 is composed of box covers on two sides and a box body. The setting of the rain discharge slope 4 prevents rainwater from accumulating at the bottom of the mounting frame 1 when the display panel 23 is washed or cleaned by rainwater, thereby avoiding affecting the observer's viewing of the display panel 23.

[0038] The bottom of the bottom support box 12 is symmetrically fixed with support columns 3, the bottom end of the support column 3 is fixed with a support flange 6, and the connection between the support flange 6 and the support column 3 is provided with reinforcing ribs in an equidistant circular array to improve the connection strength between the support flange 6 and the support column 3. The top of the support flange 6 has mounting holes in a circular array. The entire device can be fixed to the ground using the support column 3, the support flange 6 and the anchor bolts.

[0039] A common connecting plate 7 is fixed to the edge of the top wall of the mounting frame 1 by bolts, a vertical frame 8 is fixed to the bottom of the common connecting plate 7 near the bottom of the side of the mounting frame 1, a protective box 9 is fixed to one side of the vertical frame 8 by the common connecting plate 7, and the common connecting plate 7 fixes the vertical frame 8 and the protective box 9 as a whole by bolts. When the vertical frame 8 is fixed as a whole with the protective box 9, the first vertical groove 18, the transition groove 19, and the second vertical groove 20 on the side of the vertical frame 8 are exposed, so as to facilitate the insertion of the flipping and resetting assembly into the first vertical groove 18, the transition groove 19, and the second vertical groove 20.

[0040] A display panel 23 is symmetrically rotatably arranged at the bottom of the inner frame of the installation frame 1, and a common flip component for driving the display panel 23 to avoid typhoon weather is arranged inside the bottom support box 12. The common flip component includes vertical bevel gears 25, horizontal bevel gears 21, and a horizontal axis 22. One end of the horizontal axis 22 is fixedly connected to the output end of the avoidance motor 11, and the avoidance motor 11 is fixedly connected to the side of the bottom support box 12. Both ends of the horizontal axis 22 are rotatably connected to the two side surfaces of the bottom support box 12, and the outer wall of the horizontal axis 22 is fixedly provided with horizontal bevel gears 21 at equal intervals.

[0041] The bottom of the display panel 23 shaft is fixedly connected to one end of the vertical column 24, and a vertical bevel gear 25 is fixedly set at the bottom end of the vertical column 24. The vertical bevel gear 25 is stably engaged with the horizontal bevel gear 21. When viewed from the front side of the display screen, multiple horizontal bevel gears 21 are all set on the left side of the multiple vertical bevel gears 25. Therefore, when the avoidance motor 11 rotates, the multiple display panels 23 can be driven to rotate in the same direction of rotation (i.e. clockwise or counterclockwise) through the horizontal shaft 22, the vertical bevel gear 25 and the horizontal bevel gear 21, thereby ensuring the synchronization and coordination of the display content and simplifying the control system.

[0042] A vertical shift groove 17 is opened on the side of the vertical frame 8, and a cleaning component for regularly cleaning the display panel 23 is arranged inside the vertical shift groove 17. The cleaning component includes a vertical shift box 36, a top cover plate 28, a water supply pipe 39, a shift screw 14, and a cleaning pipe 30. The top cover plate 28 is fixedly set on the top of the vertical shift box 36, and a vertical screw barrel 41 is fixedly set in the middle position of the top of the vertical shift box 36. Both ends of the vertical screw barrel 41 extend out from the inner cavity of the vertical shift box 36. The shift screw 14 is screwed into the vertical screw barrel 41. Therefore, when the shift screw 14 rotates, the vertical shift box 36 extended into the vertical shift groove 17 will move in the vertical direction, and the cavity of the vertical shift box 36 except the vertical screw barrel 41 is used to temporarily store cleaning water.

[0043] The bottom of the shift screw 14 is fixedly connected to the output end of the vertical motor 5, the vertical motor 5 is fixedly connected to the bottom of the protection box 9, and the vertical shift box 36 extends into the vertical shift groove 17. In order to reduce the resistance of the vertical shift box 36 to displacement in the vertical direction, the contact position between the vertical shift box 36 and the vertical shift groove 17 is polished into a smooth surface.

[0044] The inner cavity of the bottom support box 12 is provided with a clearing component to prevent the cleaning component from being blocked. The side of the vertical movement box 36 is rotatably connected to a water supply pipe 39. The top surface of the water supply pipe 39 does not contact the bottom surface of the top cover plate 28. A cleaning pipe 30 is fixedly provided at the other end of the water supply pipe 39. Cleaning holes 31 are equidistantly provided on the side of the cleaning pipe 30. The water supply pipe 39 extends into the inner cavity of the vertical movement box 36 and an exchange hole 38 is provided on the outer wall at one end. Therefore, no matter to which angle the water supply pipe 39 is rotated, the vertical movement box 36 can always be connected with the cleaning pipe 30 through the exchange hole 38. The length of the cleaning pipe 30 is set to match the horizontal length and of the actual display panels 23 of the multiple groups.

[0045] A flip reset assembly for adjusting the direction of the cleaning hole 31 is provided at the end of the water supply pipe 39, and the flip reset assembly includes a driven gear 35, an active rod tooth 34, a driven column 37, and a step block 32. The driven gear 35 is fixedly connected to the end of the water supply pipe 39, and the active rod tooth 34 is stably meshed on the top of the driven gear 35. The driven column 37 is fixedly provided on the inner side of the active rod tooth 34. The side of the vertical frame 8 is equidistantly provided with a first vertical groove 18, a transition groove 19, and a second vertical groove 20 in sequence along the vertical direction.

[0046] The first vertical groove 18, the transition groove 19, and the second vertical groove 20 are connected end to end, the first vertical groove 18 and the second vertical groove 20 are kept parallel, the first vertical groove 18, the transition groove 19, the second vertical groove 20, and the driven column 37 are of equal width, and the driven column 37 extends into the first vertical groove 18 or the transition groove 19 or the second vertical groove 20. When the driven column 37 extends into the first vertical groove 18, the cleaning holes 31 equidistantly arranged on the sides of the multiple groups of cleaning pipes 30 are in a horizontal state, which is convenient for the set dredging component to be inserted into the cleaning hole 31. Therefore, when the dredging component is set, its power source, that is, the electric push rod 2, needs to be set horizontally. The horizontally arranged electric push rod 2 helps to more reasonably utilize the space inside the bottom support box 12. When the driven column 37 moves along the transition groove 19, the cleaning pipe 30 at the end of the water supply pipe 39 is driven to rotate continuously through the active rod teeth 34 and the driven gear 35 until the cleaning hole 31 is changed from a horizontal state to a downwardly inclined state. When the driven column 37 is displaced into the second vertical groove 20, the multiple groups of cleaning holes 31 are maintained at the required inclination angle. When the cleaning component is working, the multiple groups of cleaning holes 31 can be placed at a certain non-ninety-degree inclination angle with the display screen, so that the cleaning holes 31 can flush and gather dust in one direction of the display screen, and dust and dirt are concentrated in one direction, thereby avoiding repeated cleaning and improving cleaning efficiency.

[0047] A transverse groove 33 is provided on the side of the active rod tooth 34, and the step block 32 extends into the transverse groove 33 and is fixedly connected to the side wall of the vertical movement box 36. The step block 32 includes a wide section and a narrow section, and the narrow section of the step block 32 is as wide as the transverse groove 33. The step block 32 and the transverse groove 33 cooperate to assist the active rod tooth 34 to stably move horizontally in the horizontal direction. A blocking block 15 is fixedly provided on the side of the driven gear 35 on the side of the vertical movement box 36, and a photoelectric controller 16 is fixedly provided on the bottom of the side of the vertical frame 8. The control lines of the vertical motor 5 and the avoidance motor 11 are connected to the photoelectric controller 16. When the blocking block 15 is inserted into the photoelectric controller 16, the avoidance motor 11 can be activated, and the entire common flipping assembly can drive multiple display screens to flip. The photoelectric controller 16 and the blocking block 15 constitute a safety locking structure for the entire cleaning assembly to prevent the common flipping assembly from accidentally driving multiple display screens to flip and collide with the cleaning assembly, causing damage to the cleaning assembly.

[0048] The dredging component includes an electric push rod 2, a common plate 26, and a dredging column 27. The electric push rod 2 is fixedly connected to the side of the bottom support box 12. The common plate 26 is fixedly set at the output end of the electric push rod 2. An avoidance groove 13 is opened in the middle position of the side of the bottom support box 12. The common plate 26 extends from the side of the avoidance groove 13. The outer side of the common plate 26 is fixedly provided with dredging columns 27 at equal intervals. The positions of the dredging columns 27 and the cleaning holes 31 correspond one to one. The aperture of the dredging column 27 is the same as the aperture of the cleaning hole 31. The bottom of the vertical movement box 36 is fixedly connected to one end of the connecting bellows 40. The setting of the dredging column 27 squeezes and crushes the impurities accumulated in the cleaning hole 31 to avoid some cleaning holes 31 being blocked. Some positions of the display screen cannot be completely cleaned during cleaning, which ultimately affects the cleaning effect of the cleaning component on the display screen.

[0049] The other end of the connecting bellows 40 is fixedly connected to the water outlet end of the circulating water pump 42, and the water inlet end of the circulating water pump 42 is fixedly connected to the side of the water storage tank 29. The top of the water storage tank 29 is connected to the bottom end of the liquid replenishing bucket 10, and the liquid replenishing bucket 10 is fixedly connected to the side of the bottom support box 12. The water storage tank 29 is specifically stored inside the bottom support box 12. The connecting bellows 40 is retractable, so that when the vertical movement box 36 is displaced in the vertical direction, the water storage tank 29 is always connected to the vertical movement box 36.

[0050] It should be added that, in order to further improve the wind-shielding intelligence of the entire display screen, the photoelectric controller 16 can be connected to the wind force and direction detection system in the prior art.

[0051] The specific implementation steps and principles of the present invention are as follows:

[0052] When the entire device is in standby mode, the blocking block 15 is inserted into the photoelectric controller 16, the multiple display panels 23 are in a flush state, the entire cleaning assembly is at the bottom of the side of the mounting frame 1, the driven column 37 is in the first vertical groove 18, and the cleaning holes 31 equidistantly arranged on the side of the cleaning pipe 30 are kept in a horizontal state through the driven gear 35 and the active rod teeth 34. At this time, the electric push rod 2 drives multiple dredging columns 27 to be inserted into multiple groups of horizontally arranged cleaning holes 31 through the common plate 26. When encountering strong winds, the worker controls the avoidance motor 11 to rotate through the photoelectric controller 16, and the avoidance motor 11 drives the display panel 23 on the top of the vertical column 24 to rotate to an appropriate angle through the horizontal bevel teeth 21 and the vertical bevel teeth 25 on the horizontal shaft 22.

[0053] When the entire cleaning assembly is working, the electric push rod 2 retracts, and drives multiple dredging columns 27 to be drawn out from multiple cleaning holes 31 through the common plate 26. The vertical motor 5 and the circulating water pump 42 are started. The circulating water pump 42 pours the cleaning water in the water storage tank 29 into the cleaning pipe 30 through the connecting bellows 40, the vertical shift box 36, the exchange hole 38, and the water supply pipe 39. The vertical motor 5 drives the vertical shift box 36 to move upward through the shift screw 14, and the blocking block 15 disengages from the inside of the photoelectric controller 16. At this time, the avoidance motor 11 cannot rotate.

[0054] During this process, the driven column 37 gradually moves from the first vertical groove 18 and the transition groove 19 to the second vertical groove 20. The driven column 37 drives the driven gear 35 through the active rod teeth 34 to drive the cleaning pipe 30 at the end of the water supply pipe 39 to rotate, and drives the cleaning holes 31 on the side of the cleaning pipe 30 to rotate to a certain inclination angle. At this time, the cleaning holes 31 and the display screen are at a non-ninety-degree inclination angle, and multiple groups of cleaning holes 31 wash away dust on the surface of the display screen.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
