Description

Technical Field

[0001] This invention relates to the field of LED screen technology, and more particularly to an auxiliary heat dissipation mechanism for large LED screens. Background Technology

[0002] An LED display screen is a flat panel display composed of small LED module panels, used to display various information such as text, images, video, and recorded signals. A patent application with application number CN202222764484X and authorization announcement date of March 21, 2023, discloses a large LED screen with good heat dissipation, relating to the field of LED screen technology. It includes a mounting frame, a moving mechanism installed inside the mounting frame, a transmission mechanism partially rotatably connected inside the mounting frame near the drive mechanism and drivingly connected to the moving mechanism, with the remaining part installed inside the moving mechanism, and a heat dissipation mechanism rotatably connected to the moving mechanism near the LED screen and drivingly connected to the transmission mechanism. The advantages of this invention are: it not only automatically dissipates heat from the LED screen, but also, under the action of a drive component, simultaneously drives the heat dissipation mechanism to reciprocate and rotate while dissipating heat from the LED screen, saving costs and improving the practicality of the device; furthermore, the heat dissipation mechanisms on both sides can move synchronously towards each other inside the mounting frame, further improving the comprehensiveness of heat dissipation and the overall heat dissipation effect of the device.

[0003] The LED screen uses a mobile cooling fan to dissipate heat. While this method can effectively cool the LED screen, after prolonged use, the outside of the fan often accumulates dust and debris. To prevent this dust and debris from affecting the fan's speed and reducing its cooling efficiency, regular cleaning is required. This process is time-consuming, labor-intensive, and extremely tedious. Therefore, we propose an auxiliary cooling mechanism for large LED screens. Summary of the Invention

[0004] To address the technical problem of poor performance of existing LED screen heat dissipation components, this invention provides an auxiliary heat dissipation mechanism for large LED screens.

[0005] This invention is achieved using the following technical solution: an auxiliary heat dissipation mechanism for a large LED screen, comprising a housing and an LED screen body fixed to one side of the housing. A mounting plate is fixed to the side of the housing away from the LED screen body. The mounting plate has a loading groove, and a loading plate is rotatably connected inside the loading groove. Drive columns are fixed to both ends of the loading plate. The end of the drive column away from the loading plate is rotatably connected to the inner wall of the loading groove. The loading plate has multiple sliding grooves, and a rotating shaft slides through the sliding groove. A fan blade is fixedly sleeved on the outer wall of the rotating shaft located inside the housing. A motor is driven to the end of the rotating shaft located outside the housing. A cooling component is also provided on the mounting plate. By running the motor, the rotating shaft is driven to rotate, which in turn drives the fan blade to rotate. The rotating fan blade will dissipate heat from the LED screen body.

[0006] As a further improvement to the above solution, the cooling component includes a water tank fixed on the side of the mounting plate away from the LED screen body. A water pump is fixed on the outside of the water tank. The input end of the water pump is connected to an inlet pipe communicating with the water tank, and the output end of the water pump is connected to an outlet pipe.

The motor is fixed on the inner wall of the fixing block. A lead screw is threaded through both ends of the fixing block. A three-way solenoid valve is installed on the outlet pipe outside the housing. The output end of the three-way solenoid valve is connected to an outlet pipe. A three-way valve is installed on the outlet pipe. The output end of the device is connected to a third water outlet pipe. Multiple nozzles are installed on both the second and third water outlet pipes. Openings are provided at both ends of the housing.

A lead screw 2 with opposite thread directions at both ends is rotatably connected inside the housing. Drive sleeves are threaded onto the outer walls of both ends of the lead screw 2. A drive plate is hinged to the outer side of the drive sleeve. A fixing block 2, which is fixed to the adjacent heat dissipation window, is hinged to the end of the drive plate away from the drive sleeve. A transmission wheel 1 is fixedly sleeved on the outer wall of the drive shaft located at one end of the loading plate. A transmission wheel 2 is fixedly sleeved on the outer wall of the end of the lead screw 2 near the transmission wheel 1. A transmission belt is connected to the external transmission wheels 1 and 2. Through the operation of the cooling component, the LED screen body can be quickly cooled by air cooling and water cooling. Dust and debris attached to the outside of the heat dissipation component can be quickly removed, and the heat dissipation component can be cooled down.

[0007] As a further improvement to the above solution, a cover with multiple ventilation holes is fixed to the loading plate located inside the housing. The fan blades rotate inside the cover. The cover can protect the fan blades, and the ventilation holes can guide the airflow generated by the fan blades.

[0008] As a further improvement to the above solution, the nozzles located on the second water outlet pipe correspond to the fan blades, and the nozzles located on the third water outlet pipe correspond to the heat dissipation window. Through the nozzles corresponding to the fan blades and the heat dissipation window, the fan blades and the heat dissipation window can be effectively rinsed.

[0009] As a further improvement to the above solution, a connecting plate one is provided on the side of the loading plate away from the housing. Hydraulic cylinders with piston ends fixed to connecting plate one are fixed at both ends of the mounting plate on the side away from the housing. A connecting plate two is provided between connecting plate one and the loading plate. Multiple linkage columns with their other ends fixed to connecting plate two are fixed on the side of connecting plate one near connecting plate two. A nozzle located on water outlet pipe two is fixed to connecting plate two. Water outlet pipe one located outside the housing is fixed to connecting plate one. A nozzle located on water outlet pipe three is fixed to the mounting plate. A level valve is installed at one end of the water tank. A hydraulic cylinder fixed to the water tank is located between the water inlet port inside the water tank and the level valve. The internal filter screen has a rotatable connection on one side near the liquid level valve and a connecting shaft on the other side rotatably connected to the inner wall of the water tank. A cleaning brush rotating inside the water tank is fixed to the outer wall of the connecting shaft, and the bristles of the cleaning brush contact the filter screen.

Through the operation of the above components, the cooling water of the heat dissipation component can be filtered, the heat dissipation component can be adaptively adjusted, and the filter component can be unblocked.

[0010] As a further improvement to the above solution, a second movable door is hinged to the outer side of the shell and the outer side of the water tank.

By opening the second movable door, the components inside the shell can be inspected and maintained, and the components inside the water tank can be inspected and maintained.

[0011] As a further improvement to the above solution, one end of the lead screw is connected to a motor three fixed on the loading plate, and the other end of the lead screw is rotatably connected to a stabilizing plate fixed on the loading plate. The operation of the motor three can drive the lead screw to rotate, and the stabilizing plate can improve the stability of the lead screw.

[0012] As a further improvement to the above solution, the end of the second water outlet pipe away from the tee is closed, and the end of the third water outlet pipe away from the tee is also closed. By using the second and third water outlet pipes, which are closed at one end, water can be prevented from flowing out from the openings of the second and third water outlet pipes.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example 1:

[0028] Combination Figure 1 This embodiment provides an auxiliary heat dissipation mechanism for a large LED screen, including a housing 1 and an LED screen body 2 fixed to one side of the housing 1. A mounting plate 3 is fixed to the side of the housing 1 away from the LED screen body 2. The mounting plate 3 has a loading groove, and a loading plate 4 is rotatably connected inside the loading groove. Drive columns are fixed to both ends of the loading plate 4. The end of the drive column away from the loading plate 4 is rotatably connected to the inner wall of the loading groove. The loading plate 4 has multiple sliding grooves, and a rotating shaft slides through the inside of the sliding grooves. A fan blade 18 is fixedly sleeved on the outer wall of the rotating shaft located inside the housing 1. A motor is drivenly connected to the end of the rotating shaft located outside the housing 1. A cooling component is also provided on the mounting plate 3.

[0029] The implementation principle of the auxiliary heat dissipation mechanism for a large LED screen in this application embodiment is as follows: when the LED screen body 2 is running, it generates a certain amount of heat. The operation of motor 1 drives the rotating shaft to rotate, which in turn drives the fan blades 18 to rotate. At this time, the rotating fan blades 18 will perform heat dissipation work on the LED screen body 2.

[0030] Example 2:

[0031] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5This embodiment, based on Embodiment 1, further improves upon the following: the cooling component includes a water tank 5 fixed to the side of the mounting plate 3 away from the LED screen body 2. A water pump 6 is fixed to the outside of the water tank 5. The input end of the water pump 6 is connected to an inlet pipe 7 communicating with the water tank 5. The output end of the water pump 6 is connected to an outlet pipe 8. The end of the outlet pipe 8 away from the water pump 6 passes through the housing 1 and enters the interior of the water tank 5. The outlet pipe 8 located inside the housing 1 is coiled and fixed to the inner wall of the housing 1. A gear 1 is fixedly sleeved on the outer wall of the drive column. A motor 2 is fixedly mounted on one side of the gear 1 on the inner wall of the housing 1. The output end of the motor 2 is connected to a drive shaft. A gear 21 meshing with the gear 1 is fixedly sleeved on the outer wall of the drive shaft. The loading plate 4 is away from the housing 1. A fixing block 20 is fixed on one side, and a motor is fixed on the inner wall of the fixing block 20. Both ends of the fixing block 20 are threaded with lead screws. A three-way solenoid valve 9 is installed on the water outlet pipe 8 located outside the housing 1. The output end of the three-way solenoid valve 9 is connected to a second water outlet pipe 11. A three-way valve 13 is installed on the second water outlet pipe 11, and the output end of the three-way valve 13 is connected to a third water outlet pipe 10. Multiple nozzles 12 are installed on both the second and third water outlet pipes 11 and 10. Openings 14 are provided at both ends of the housing 1. A heat dissipation window 15 is provided on the outer side of the housing 1 to close the openings 14. A fixing block 1 is hinged to the end of the heat dissipation window 15 near the mounting plate 3 and fixed to the housing 1. A lead screw 16 with opposite thread directions is rotatably connected inside the housing 1. The outer wall of each end is threaded with a drive sleeve 29. A drive plate 17 is hinged to the outer side of the drive sleeve 29. A fixed block 2, which is fixed to the adjacent heat dissipation window 15, is hinged to the end of the drive plate 17 away from the drive sleeve 29. A transmission wheel 1 is fixedly sleeved on the outer wall of the drive shaft located at one end of the loading plate 4. A transmission wheel 2 is fixedly sleeved on the outer wall of the screw 16 near the end of the transmission wheel 1. A transmission belt is connected to the external transmission of the transmission wheel 1 and the transmission wheel 2. When the rotating fan blade 18 performs heat dissipation work on the LED screen body 2, the rotation of the screw 1 drives the fixed block 20 to move vertically. At this time, the fixed block 20, which moves vertically, will drive the motor 1, the shaft and the fan blade 18 to move. The fan blade 18, which moves vertically, will then displace the LED screen body 2. Heat dissipation is carried out in other locations. Through the heat dissipation window 15, the heat emitted by the LED screen body 2 inside the housing 1 can be discharged. At the same time, the operation of the water pump 6 drives the water inlet pipe 7 to draw water from the water tank 5. The water entering the water inlet pipe 7 will be blown into the water outlet pipe 8 and then transported into the water tank 5. At this time, the water running in the water outlet pipe 8 will absorb the heat emitted by the LED screen body 2 inside the housing 1. When the fan blade 18 has been working for a long time and a certain amount of dust and debris has accumulated on the outside of the fan blade 18, the operation of the second motor will drive the drive shaft to rotate, which will drive the gear 21 and the gear 1 to rotate, drive the drive column to rotate, and drive the loading plate 4 to rotate.At this time, the rotating loading plate 4 will drive the motor 1, the shaft and the fan blade 18 to rotate. When the fan blade 18 is aligned with the nozzle 12, the operation of the three-way solenoid valve 9 will transport the water inside the first water outlet pipe 8 to the second water outlet pipe 11. The water entering the second water outlet pipe 11 will be sprayed out through the nozzle 12. At this time, the water sprayed out by the nozzle 12 will wash the fan blade 18, remove the debris and dust attached to the outside of the fan blade 18, and cool the fan blade 18 to improve its heat dissipation performance, avoiding the need for staff to clean the fan blade 18 regularly. When the drive shaft rotates, it will drive the first transmission wheel to rotate, and through the transmission wheel 1, the second transmission wheel and the transmission belt, the water will be transported to the fan blade 18. The drive mechanism rotates the transmission wheel 16, which in turn rotates the lead screw 16, causing the drive sleeve 29 to shift and the drive plate 17 and heat dissipation window 15 to deflect. When the fan blade 18 aligns with the nozzle 12, the heat dissipation window 15 aligns with the corresponding nozzle 12. Through the operation of the three-way solenoid valve 9 and the cooperation of the three-way valve 13, the water entering the outlet pipe 11 also enters the outlet pipe 10. The water entering the outlet pipe 10 will then be sprayed out through the nozzle 12. At this time, the water sprayed out by the nozzle 12 will rinse and clean the heat dissipation window 15, preventing the heat dissipation holes of the heat dissipation window 15 from being blocked by external dust and debris, thus preventing the housing 1 from performing normal heat dissipation.

[0032] The loading plate 4 located inside the housing 1 is fixed with a cover 19 having multiple ventilation holes. The fan blade 18 rotates inside the cover 19. The cover 19 can protect the fan blade 1, and the ventilation holes can guide the airflow generated by the fan blade 18.

[0033] The nozzle 12 located on the second water outlet pipe 11 corresponds to the fan blade 18, and the nozzle 12 located on the third water outlet pipe 10 corresponds to the heat dissipation window 15. Through the nozzle 12 corresponding to the fan blade 18 and the heat dissipation window 15, the fan blade 18 and the heat dissipation window 15 can be effectively rinsed.

[0034] Example 3:

[0035] Combination Figure 6 and Figure 7This embodiment, based on embodiment 2, further improves upon the following: A connecting plate 22 is provided on the side of the loading plate 4 away from the housing 1; hydraulic cylinders 28 with piston ends fixed to the connecting plate 22 are fixed at both ends of the mounting plate 3 on the side away from the housing 1; a connecting plate 27 is provided between the connecting plate 22 and the loading plate 4; multiple linkage columns with their other ends fixed to the connecting plate 27 are fixed on the side of the connecting plate 22 near the connecting plate 27; and the nozzle 12 located on the water outlet pipe 11 is fixed to the connecting plate 27, located outside the housing 1. The water outlet pipe 18 is fixed to the connecting plate 22, and the nozzle 12 located on the water outlet pipe 10 is fixed to the mounting plate 3. A level valve is installed at one end of the water tank 5. A filter screen 23 is fixed inside the water tank 5 between the inlet pipe 7 port and the level valve. The filter screen 23 is rotatably connected to the side near the level valve, and the other end is rotatably connected to the inner wall of the water tank 5. A cleaning brush 25 is fixed to the outer wall of the adapter shaft 24 and rotates inside the water tank 5. The bristles of the cleaning brush 25 are in contact with the filter screen 23. The water tank 5 has a sliding opening. A rack plate 26 slides through the moving groove and sliding groove. A drive gear is fixedly sleeved on the outer wall of the adapter shaft 24. The rack plate 26 located inside the water tank 5 meshes with the drive gear. The end of the rack plate 26 located outside the water tank 5 is fixed to the connecting plate 1 22. By operating the hydraulic cylinder 28, the connecting plate 1 22 and the connecting plate 27 can be moved, thereby moving the nozzle 12. At this time, the corresponding position of the nozzle 12 can be adjusted. Through the liquid level valve, sufficient water can be injected into the water tank 5. Through the filter screen 23, the water can be filtered. The water injected into the water tank 5 is filtered. When the connecting plate 22 is displaced, it will drive the rack plate 26 to move. The displaced rack plate 26 will drive the drive gear to rotate. The rotating drive gear will drive the adapter shaft 24 to rotate. At this time, the rotating adapter shaft 24 will drive the cleaning brush 25 to rotate. The rotating cleaning brush 25 will clean the filter screen 23 to prevent the filter screen 23 from becoming clogged after a long period of filtration, thus improving the filter screen 23's endurance.

[0036] A second movable door is hinged to the outside of the housing 1, and a second movable door is hinged to the outside of the water tank 5. A sealing ring is provided on the outside of the second movable door. By opening the second movable door, the components inside the housing 1 can be inspected and maintained, and the components inside the water tank 5 can be inspected and maintained.

[0037] One end of the lead screw is connected to a motor three fixed on the loading plate 4, and the other end of the lead screw is rotatably connected to a stabilizing plate fixed on the loading plate 4. The motor three drives the lead screw to rotate, and the stabilizing plate improves the stability of the lead screw.

[0038] The end of the second water outlet pipe 11 that is away from the tee 13 is closed, and the end of the third water outlet pipe 10 that is away from the tee 13 is also closed. By using the second water outlet pipe 11 and the third water outlet pipe 10, which are closed at one end, water can be prevented from flowing out from the openings of the second water outlet pipe 11 and the third water outlet pipe 10.

[0039] The mounting plate 3 has multiple sliding holes, and the water outlet pipe 8 slides inside the sliding holes, allowing the water outlet pipe 8 to move flexibly through the sliding holes.

[0040] Working principle: When the LED screen body 2 is running, it generates heat. Motor 1 drives the rotating shaft to rotate, which in turn drives the fan blades 18. The rotating fan blades 18 then dissipate heat from the LED screen body 2. Simultaneously, Motor 3 drives the lead screw 1 to rotate, causing the fixed block 20 to move vertically. This vertical displacement of the fixed block 20 then moves Motor 1, the rotating shaft, and the fan blades 18, allowing the fan blades 18 to dissipate heat from other parts of the LED screen body 2. The heat dissipated from the LED screen body 2 inside the housing 1 can be expelled through the heat dissipation window 15. At the same time, the heat can be further dissipated through the heat dissipation window 15. The operation of water pump 6 drives water inlet pipe 7 to draw water from water tank 5. The water entering water inlet pipe 7 will be blown into water outlet pipe 8 and then transported to water tank 5. At this time, the water in water outlet pipe 8 will absorb the heat emitted by the LED screen body 2 inside the housing 1. After the fan blade 18 has been working for a long time, when a certain amount of dust and debris adheres to the outside of the fan blade 18, the operation of motor 2 will drive the drive shaft to rotate, drive gear 21 and gear 1 to rotate, drive the drive column to rotate, and drive the loading plate 4 to rotate. At this time, the rotating loading plate 4 will drive motor 1, shaft and fan blade 18 to rotate. When the fan blade 18 is aligned with the nozzle 12, the operation of the three-way solenoid valve 9 will cause the fan blade 18 to rotate. The water inside outlet pipe 8 is transferred to outlet pipe 11. The water entering outlet pipe 11 is then sprayed out through nozzle 12. This spray washes the fan blades 18, removing debris and dust, and cooling them to improve heat dissipation. This eliminates the need for regular cleaning. When the drive shaft rotates, it drives transmission wheel 1 to rotate. Through the transmission of transmission wheel 1, transmission wheel 2, and the transmission belt, transmission wheel 2 rotates, which in turn drives lead screw 16, causing displacement of drive sleeve 29. This displacement causes drive plate 17 and heat dissipation window 15 to deflect. When the fan blades 18 align with nozzle 12, heat dissipation is achieved. Window 15 corresponds to the nozzle 12. Through the operation of the three-way solenoid valve 9 and the cooperation of the three-way valve 13, the water entering the second outlet pipe 11 will also enter the third outlet pipe 10. The water entering the third outlet pipe 10 will be sprayed out through the nozzle 12. At this time, the water sprayed out by the nozzle 12 will wash and clean the heat dissipation window 15, preventing the heat dissipation holes of the heat dissipation window 15 from being blocked by external dust and debris, which would prevent the housing 1 from performing normal heat dissipation. Through the operation of the hydraulic cylinder 28, the connecting plate 22 and the second connecting plate 27 can be moved, thereby moving the nozzle 12. At this time, the corresponding position of the nozzle 12 can be adjusted. When the connecting plate 22 moves, it will move the rack plate 26.The displaced rack and pinion plate 26 drives the drive gear to rotate, which in turn drives the adapter shaft 24 to rotate. The rotating adapter shaft 24 then drives the cleaning brush 25 to rotate, cleaning the filter screen 23 and preventing its pores from becoming clogged after prolonged filtration, thus improving the filter screen 23's operating time.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
