Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a drainage and diversion structure for an outdoor LED display screen. Background Art

[0002] LED display screens are often installed outdoors as giant advertising screens. In order to prevent rain from damaging the back panel of the display screen, the frequency of contact between the LED display screen and rain needs to be reduced. Therefore, a special drainage diversion structure is often required to drain the rainwater. Existing drainage diversion structures are mostly single drainage and drainage. Other debris in the rainwater can easily block the drain outlet, and the debris in the device is not easy to clean. At the same time, the water storage height of the device cannot be adjusted according to needs, and the utilization rate of rainwater is not high.

[0003] The prior art discloses a workshop dust removal device with application number 202021948730.1. The device screens out all debris in rainwater through a partition, making the device easier to clean. At the same time, the drainage height of the connecting pipe in the water tank can be adjusted, so that the water storage height of the water tank of the device can be adjusted. The rainwater in the water tank can effectively dissipate heat for the display screen. The water in the water tank in the device is easily affected by the external environment, especially in summer. The water in the water tank is easy to evaporate in a high temperature environment, and when the water temperature is too high, the heat dissipation effect on the display screen is not good, and there are certain limitations. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a drainage and diversion structure for an outdoor LED display screen to solve the technical problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drainage and diversion structure for an outdoor LED display screen, comprising a support plate, a water tank and a top block are provided on the top of the support plate, a display screen is installed on one side of the water tank, a float is provided on the top of the water tank, a piston is provided at the bottom of the float, a water pump is provided on the bottom of the water tank, a delivery pipe is connected to the water outlet of the water pump, guide wheels are provided on both sides of the top of the water tank, a traction rope is provided on the outer surface of the guide wheel, and a counterweight block and a cleaning box are connected at both ends of the traction rope, a second guide rod is provided inside the cleaning box, a sealing plate is connected to the outer surface of the second guide rod, a sealing plug is connected to the bottom of the sealing plate, and a perforated plate and a cleaning brush are provided on the inner wall of the cleaning box.

[0006] Furthermore, a water inlet and a water outlet are respectively provided at the top and the bottom of the cleaning box, and the water outlet is matched with the sealing plug.

[0007] By adopting the above technical solution, the staff turns on the power, and the water pump pumps the water in the water tank into the water inlet of the cleaning box through the delivery pipe. Under the action of gravity, the sealing plug is embedded in the water outlet of the cleaning box.

[0008] Furthermore, a first guide rod is provided on one side of the top of the support plate, a sliding block is provided outside the first guide rod, and the sliding block is fixed to the cleaning box.

[0009] By adopting the above technical solution, when the cleaning box is filled with water, the cleaning box moves downward on the first guide rod through the slider under the action of gravity, and when the water in the cleaning box flows out, it moves upward on the first guide rod through the traction rope.

[0010] Furthermore, the cleaning brush is made of sponge, and the cleaning brush is in contact with the display screen.

[0011] By adopting the above technical solution, the sponge has strong water absorption, can better absorb stains, and has a more thorough cleaning effect. At the same time, the sponge material is soft and can better fit the surface of the display screen without scratching or leaving scratches.

[0012] Furthermore, the guide wheels are provided in two groups, each group having two wheels.

[0013] By adopting the above technical solution, the traction rope is always fitted in the groove of the guide wheel under the action of tension, and is guided by the guide wheel to make the cleaning box and the counterweight blocks at both ends of the traction rope move upward or downward.

[0014] Furthermore, a slide groove is provided on the upper inner wall of the water tank, and slide rods are symmetrically provided on both sides of the float, and one end of the slide rod is slidably matched with the slide groove.

[0015] By adopting the above technical solution, the sliding rod can prevent the float from moving left and right, thereby causing the piston to be misplaced. When it rains, rainwater enters the water tank. Under the action of buoyancy, the float drives the piston to move upward, allowing rainwater to enter the water tank. When the weather is clear, the piston blocks the water inlet of the water tank to prevent water evaporation.

[0016] Furthermore, a filter plate is provided in the water tank, and the filter plate is inclined. A scraper is provided on the top of the filter plate, and a push-pull rod is provided on the outer surface of the scraper.

[0017] By adopting the above technical solution, the filter plate can filter the rainwater entering the water tank and isolate the fallen leaves and debris mixed in the rainwater to avoid clogging the water pump. The inclined setting allows the fallen leaves and debris to accumulate on one side of the filter plate. The staff drives the scraper to move by pulling the push-pull rod, so that the fallen leaves and debris on the filter plate are pushed out of the movable door for easy collection.

[0018] Furthermore, a movable door is provided on the outer surface of the water tank, a handle is provided on the movable door, and the movable door corresponds to the filter plate.

[0019] By adopting the above technical solution, when it is necessary to clean the fallen leaves and debris in the water tank, the staff pulls the handle to open the movable door, and removes the fallen leaves and debris on the filter plate for collection.

[0020] Furthermore, two groups of traction ropes are provided, and the two groups of traction ropes are symmetrically distributed with the longitudinal axis of the cleaning box as the center.

[0021] By adopting the above technical solution, the two sets of traction ropes can make the cleaning box more evenly stressed, thereby preventing the cleaning box from tilting and affecting the cleaning effect.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] 1. The utility model is provided with a water tank, a float and a piston. When it rains, rainwater automatically enters the water tank. Under the buoyancy of the float, the float drives the piston to leave the water inlet of the water tank, so that rainwater enters the water tank for collection. When the weather is clear, the piston blocks the water inlet to prevent water evaporation. Since the water tank is in contact with the back plate of the display screen, the display screen can be cooled by the principle of heat conduction, and at the same time, a water source is provided for cleaning the display screen, thereby improving the utilization rate of rainwater.

[0024] 2. The utility model is provided with a cleaning box, a cleaning brush, a sealing plug, a top block, a traction rope and a counterweight. When the display screen needs to be cleaned, the staff turns on the power supply, and the water pump sends the water in the water tank into the cleaning box through the delivery pipe. The overall weight of the cleaning box is greater than the counterweight. The cleaning box gradually moves downward, and the water moistens the cleaning brush, so that the cleaning brush wipes the surface of the display screen. When the cleaning box moves to the top of the top block, the top block lifts the sealing plug to discharge the water in the cleaning box. The weight of the counterweight is greater than the overall cleaning box, and the cleaning box is driven back to its original position by the traction rope, so as to achieve the purpose of cleaning the display screen.

[0025] 3. The utility model is provided with a filter plate, a scraper and a movable door. When it is necessary to clean the fallen leaves and debris in the water tank, the staff opens the movable door by pulling the handle, and then pulls the pull rod to make the scraper push the fallen leaves and debris on the filter plate out for collection, and then returns to its original position, so as to avoid the accumulation of fallen leaves and debris to block the filter plate and affect the collection of rainwater.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1: A drainage and diversion structure for an outdoor LED display screen, such as Figure 1-Figure 6 As shown, it includes a support plate 1, a water tank 3 and a top block 4 are provided on the top of the support plate 1, a display screen 2 is installed on one side of the water tank 3, a float 19 is provided on the top of the water tank 3, a piston 20 is provided at the bottom of the float 19, a water pump 12 is provided at the bottom of the water tank 3, and a delivery pipe 8 is connected to the water outlet of the water pump 12, guide wheels 5 are provided on both sides of the top of the water tank 3, a traction rope 6 is provided on the outer surface of the guide wheel 5, and a counterweight block 7 and a cleaning box 9 are connected at both ends of the traction rope 6, a second guide rod 15 is provided inside the cleaning box 9, a sealing plate 13 is connected to the outer surface of the second guide rod 15, and a sealing plug 14 is connected to the bottom of the sealing plate 13, a perforated plate 16 and a cleaning brush 17 are provided on the inner wall of the cleaning box 9, and the cleaning brush 17 is made of sponge, and the cleaning brush 17 is in contact with the display screen 2, the sponge has strong water absorption, can better absorb stains, and the cleaning effect is more thorough, and the sponge is soft and can better fit the surface of the display screen 2 without scratching or leaving scratches.

[0036] Referring to Figures, Figures and Figures, in the above embodiment, a water inlet and a water outlet are respectively provided at the top and the bottom of the cleaning box 9, and the water outlet of the cleaning box 9 is matched with the sealing plug 14. When the staff turns on the power, the water pump 12 pumps the water in the water tank 3 into the water inlet of the cleaning box 9 through the delivery pipe 8. Under the action of gravity, the sealing plug 14 is embedded in the water outlet of the cleaning box 9.

[0037] Referring to Figure 3, in the above embodiment, a first guide rod 11 is provided on one side of the top of the support plate 1, a slider 10 is provided on the outside of the first guide rod 11, and the slider 10 is fixed to the cleaning box 9. When the cleaning box 9 is filled with water, under the action of gravity, the cleaning box 9 moves downward on the first guide rod 11 through the slider 10. When the water in the cleaning box 9 flows out, it moves upward on the first guide rod 11 through the traction rope 6.

[0038] Referring to Figure 3, in the above embodiment, the guide wheels 5 are provided with two groups, each group has two members. Under the action of tension, the traction rope 6 always fits in the groove of the guide wheel 5 and is guided by the guide wheel 5, so that the cleaning box 9 and the counterweight block 7 at both ends of the traction rope 6 move upward or downward.

[0039] Referring to Figures, Figures and Figures, in the above embodiment, a slide groove is opened on the upper inner wall of the water tank 3, and slide rods are symmetrically provided on both sides of the float 19, and one end of the slide rod slides with the slide groove. The slide rod can prevent the float 19 from moving left and right, thereby causing the piston 20 to be misplaced. When it rains, rainwater enters the water tank 3. Under the action of buoyancy, the float 19 drives the piston 20 to move upward, so that rainwater enters the inside of the water tank 3. When the weather is fine, the piston 20 blocks the water inlet of the water tank 3 to prevent water evaporation.

[0040] Referring to Figure 3, in the above embodiment, two groups of traction ropes 6 are provided, and the two groups of traction ropes 6 are symmetrically distributed with the longitudinal axis of the cleaning box 9 as the center. The two groups of traction ropes 6 can make the cleaning box 9 more evenly stressed and avoid the cleaning box 9 from tilting, thereby affecting the cleaning effect.

[0041] Referring to Figures, Figures and Figures, in the above embodiment, a movable door 21 is provided on the outer surface of the water tank 3, and a handle is provided on the movable door 21. The movable door 21 corresponds to the filter plate 18. When it is necessary to clean the fallen leaves and debris in the water tank 3, the staff pulls the handle to open the movable door 21, and the fallen leaves and debris on the filter plate 18 are removed for collection.

[0042] Embodiment 2: Based on the above embodiment 1, although the fallen leaves and debris on the filter plate 18 can be collected by setting the movable door 21, there will still be omissions. Now, the filter plate 18 is tilted, and a scraper 22 and a push-pull rod are set.

[0043] Referring to Figures, Figures and Figures, in the above embodiment, the filter plate 18 is tilted so that fallen leaves and debris can be accumulated on one side of the filter plate 18. The staff can move the scraper 22 by pulling the push-pull rod, so that the fallen leaves and debris on the filter plate 18 are pushed out of the movable door 21 for easy collection.

[0044] The implementation principle of the utility model is as follows: when it rains, under the action of buoyancy, the float 19 drives the piston 20 to leave the water inlet of the water tank 3, so that rainwater enters the water tank 3 for collection. When it is sunny, the piston 20 blocks the water inlet. When it is necessary to clean the display screen 2, the staff turns on the power supply, and the water pump 12 delivers the water in the water tank 3 into the cleaning box 9 through the delivery pipe 8, so that the overall weight of the cleaning box 9 is greater than the counterweight block 7. The cleaning box 9 gradually moves downward on the first guide rod 11 through the slider 10, and the water in the cleaning box 9 slowly penetrates into the display screen 2 through the orifice plate 16. The cleaning brush 17 is inside, so that the cleaning brush 17 wipes the surface of the display screen 2. At the same time, with the help of the guide wheel 5, the counterweight block 7 is moved upward under the drive of the traction rope 6. When the cleaning box 9 moves to the top of the top block 4, the top block 4 lifts the sealing plug 14 away from the water outlet of the cleaning box 9, thereby driving the sealing plate 13 to move upward on the second guide rod 15, so that the water in the cleaning box 9 is discharged. At this time, the weight of the counterweight block 7 is greater than the entire cleaning box 9. The counterweight block 7 moves downward under the action of gravity, and then drives the cleaning box 9 back to its original position through the traction rope 6.

[0045] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
