Description

Technical Field

[0001] This invention relates to the technical field of data display racks, and specifically to a data display rack and its usage method. Background Technology

[0002] Data display racks are typically used to display data after intelligent analysis. For example, data analysis tables obtained after calculation and analysis by intelligent computers are displayed on the screen of the data display rack, making it convenient for users to view and analyze the data.

[0003] Common data display racks are usually simple in structure and only have the function of displaying data. However, data display racks exposed to the outdoors will accumulate a lot of dirt on their screens after being exposed to sun and rain for a long time, which requires staff to clean them regularly, which is quite troublesome.

[0004] Therefore, there is an urgent need for a data display rack and its usage method to solve the problem that outdoor data display racks cannot automatically clean the stains on the display screen. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a data display rack and its usage method to solve the problem that outdoor data display racks cannot automatically clean stains from the display screen.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A data display rack includes a support base, a storage box, a display panel, an energy storage unit, a rain collection component, and a cleaning component. The cleaning component includes a water column, a pressure box, and a cleaning roller. The storage box is mounted on the support base, and a support column is connected to the upper end of the storage box. The display panel, the rain collection component, and the energy storage unit for power supply are mounted on the support column. A horizontally arranged water column is mounted on the top of the side of the display panel where the display screen is located. The two ends of the water column are connected to the pressure box located below via return spring ropes. The upper end of the pressure box is open, and a horizontal cleaning roller is mounted on the lower end. The pressure box is also equipped with a controllable drain pipe. The rain collection component is used to collect rainwater and store it in the storage box. The storage box is connected to the water column and is used to controllably supply water to the water column. The water column is used to supply water to the pressure box. When the water storage volume increases, the pressure box moves the cleaning roller downward along the surface of the display screen due to the increase in its own weight, or when the drain pipe drains water, the pressure box moves the cleaning roller upward by the return spring rope due to the decrease in its own weight.

[0007] To optimize the above technical solution, the specific measures also include: Furthermore, a row of water distribution pipes is provided horizontally on the side of the water storage column near the pressure box, the water distribution pipes are used to inject water into the pressure box, and a row of water spray pipes is provided horizontally on the side of the water storage column near the display screen, the water spray pipes are used to spray water onto the display screen.

[0008] Furthermore, the two ends of the water column are respectively connected to the movable frame located below by a reset spring rope. The two sides of the movable frame are slidably set on the display plate. The upper end of the movable frame is used to install a water pressure box.

A water-pressing plate can also be slidably installed in the lower chamber. The water-pressing plate is in sealed contact with the four walls of the lower chamber. A push frame is provided on the side of the water-pressing plate near the push column. The end of the push frame away from the water-pressing plate is slidably installed in the reciprocating arc groove. The lower chamber on the side of the water-pressing plate away from the push frame is connected to the water storage column through a water inlet pipe. The upper chamber of the storage box is used to connect to the rainwater collection component and is provided with an overflow outlet. A drain pipe connecting the upper chamber and the lower chamber is provided on the support plate. A one-way valve is provided in the drain pipe to allow rainwater to flow from the upper chamber into the lower chamber.

[0011] Furthermore, the upper cavity of the storage box is also provided with a vertically arranged filter plate, the rain collection component is connected to the upper cavity on one side of the filter plate, the upper cavity on the other side of the filter plate is connected to the lower cavity through a drain pipe, and the side wall of the upper cavity of the storage box is also provided with an openable and closable discharge opening.

[0012] Furthermore, the rain collection assembly includes a rain collection disc, a water drop column, and cutting blades. A rain collection disc with an open top is installed at the upper end of the support column. A water drop column is installed inside the support column. The bottom of the rain collection disc is connected to the inlet end of the water drop column through a water collection pipe that passes through the inside of the support column. The outlet end of the water drop column is connected to the upper cavity of the storage tank. Cutting blades are also provided inside the water drop column through a linkage roller. One end of the linkage roller is sealed and rotatably passes through the water drop column and the support column, and a linkage gear is fixedly sleeved on it. A drive gear is fixedly sleeved on the drive roller located in the dry cavity of the storage tank. The drive gear and the linkage gear are connected by a transmission belt meshing. The upper end of the storage tank is provided with a hole through which the transmission belt can pass.

[0013] Furthermore, the energy storage unit includes a photovoltaic panel and an energy storage battery. A mounting frame is fixedly installed on one side of the support column. An angle-adjusting roller is rotatably mounted on the mounting frame. Two steering brackets are fixedly mounted on the angle-adjusting roller. The photovoltaic panel is fixedly mounted on the two steering brackets. A driven gear is also fixedly mounted on the angle-adjusting roller. A driven roller is rotatably mounted inside the support column. A transmission gear is fixedly mounted on the driven roller. The transmission gear, the driving gear, and the linkage gear are connected by a transmission belt. An electric self-locking wheel is also provided on the driven roller. A drive gear is fixedly mounted on the outside of the electric self-locking wheel. A transmission gear plate that can slide out of the support column is movably mounted inside the support column and above the drive gear through two telescopic limit rods. The transmission gear plate meshes with the drive gear and the driven gear respectively. The energy storage battery is installed inside the support column.

[0014] Furthermore, the bottom of the support base is equipped with multiple omnidirectional casters, and the bottom of the support base is also fixedly installed with a support plate by a support spring. Multiple support pads are fixedly installed at the lower end of the support plate, and the upper end of the support plate is slidably connected to the support base by a pressing rod. A locking plate is movably installed on the upper part of the pressing rod, and a locking component for cooperating with the locking plate is fixedly installed on the support base.

[0015] Furthermore, a method of use, applied to the aforementioned data display rack, is characterized by comprising the following steps: The data to be displayed is transmitted to the display screen via a CNC computer and powered by an energy storage unit. The rainwater collection component collects rainwater and stores it in a storage tank. Then, the storage tank is controlled to supply water to the water column, which in turn supplies water to the open-topped pressure box to increase the water storage capacity. When the pressure box moves downward due to its own weight, the return spring rope is stretched, which drives the cleaning roller on it to move downward synchronously. The moving cleaning roller cleans the surface of the display screen. When the pressure box and the cleaning roller move to the bottom of the display screen, the drain pipe on the pressure box is opened to drain water. The pressure box's own weight decreases and it is driven upward by the return spring rope to reset, thus completing one cleaning operation.

[0016] The beneficial effects of this invention are: This invention, through its cleaning components and other features, collects rainwater using a rain collection component and stores it in a storage tank. The storage tank then controls the flow of water into a water column, which in turn supplies water to a pressure box with an open top. This pressure box moves, causing a cleaning roller on it to move synchronously. The cleaning roller then cleans the display screen, removing dust and impurities, thus automatically cleaning the screen and solving the problem of outdoor data display racks being unable to automatically clean their displays. Simultaneously, the overflowing water from the pressure box also rinses the cleaning roller, extending its service life.

[0017] This invention, through the setting of a rain collection tray, can collect rainwater when it rains, and store the rainwater by filtering out impurities. At the same time, it can controllably realize processes such as water spraying and wiping of the display screen, realizing automatic dust removal of the display screen without manual cleaning, and improving the display effect.

[0018] This invention, through the installation of photovoltaic panels and other devices, can receive sunlight and convert solar energy into electrical energy. The angle and position of the photovoltaic panels can be adjusted as needed according to the position of sunlight to ensure energy storage effect. It can also power intelligent control panels, displays and servo motors, effectively reducing dependence on external power sources and making it more energy-efficient and environmentally friendly.

[0019] This invention utilizes multiple omnidirectional casters on a support base, combined with the pressure and fixing effect of a support pad, to enable the display rack to be adjusted and positioned at any time. It balances mobility and stability, allowing for quick changes in the display rack's location to suit different display scenarios. Attached Figure Description

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4As shown, an embodiment of the present invention provides a data display rack, comprising a support base 1, a storage box 4, a display panel 5, an energy storage unit, a rain collection component, and a cleaning component. The cleaning component includes a water collection column 43, a water pressure box 44, and a cleaning roller 8. The support base 1 has a storage box 4, and the upper end of the storage box 4 is connected to a support column 15 for support. The support column 15 is equipped with the display panel 5, the rain collection component, and the energy storage unit for power supply. The top of one side of the display panel 5, which has a touch-sensitive display screen 6 for displaying data analysis tables, has a horizontally arranged water collection column 43. The two ends of the water collection column 43 are respectively connected by a reset spring rope. 10 connects to the water pressure box 44 located below. The upper end of the water pressure box 44 is open, and the lower end is equipped with a horizontal cleaning roller 8. The water pressure box 44 is also equipped with a controllable drain pipe 12. The rainwater collection component is used to collect rainwater and store it in the storage box 4. The storage box 4 is connected to the water storage column 43 and is used to controllably supply water to the water storage column 43. The water storage column 43 is used to supply water to the water pressure box 44. The water pressure box 44 is used to move the cleaning roller 8 downward along the surface of the display screen 6 due to the increase in its own weight after the water storage volume increases, or to drive the cleaning roller 8 upward to reset due to the decrease in its own weight after the drain pipe 12 drains water.

[0024] This invention, through its cleaning components and other features, allows for the collection of rainwater in a storage tank 4. The storage tank 4 then controls the flow of water into a water column 43, which in turn supplies water to a pressure box 44 with an open top. This pressure box 44 moves, causing the cleaning roller 8 to move synchronously. The cleaning roller 8 then cleans the display screen 6, removing dust and impurities, thus achieving automatic cleaning of the display screen 6. This solves the problem of outdoor data display racks being unable to automatically clean their displays. Simultaneously, the overflowing water from the pressure box 44 also rinses the cleaning roller 8, extending its service life.

[0025] As attached Figure 5 As shown, in a specific embodiment based on the above, a row of water distribution pipes is provided horizontally on the side of the water column 43 near the pressure box 44. The water distribution pipes are used to inject water into the pressure box 44. A row of water spray pipes 11 is provided horizontally on the side of the water column 43 near the display screen 6. The water spray pipes 11 are used to spray water onto the display screen 6.

[0026] In this way, water can be continuously injected into the pressure water box 44 through the water distribution pipe to meet the water supply needs of the pressure water box 44; and water can be sprayed onto the display screen 6 through the spray pipe 11 to increase the cleaning effect. Specifically, the water sprayed out of the water distribution pipe will fall directly into the pressure water box 44 on the movable frame 42 and will accumulate and be stored in the pressure water box 44; the water sprayed out through the spray pipe 11 will be sprayed directly onto the display screen 6, which can directly rinse the display screen 6, thereby improving the cleaning effect of the display screen 6.

[0027] In another specific embodiment based on the above, the two ends of the water column 43 are respectively connected to the movable frame 42 located below by the reset spring rope 10. The two sides of the movable frame 42 are slidably arranged on the display plate 5. The upper end of the movable frame 42 is used to install the pressure water box 44. A cleaning roller 8 for cleaning the display screen 6 is rotatably installed on the side of the movable frame 42 near the display screen 6.

[0028] Therefore, the movable frame 42 facilitates the assembly and disassembly of structures such as the cleaning roller 8. Simultaneously, the movable frame 42, slidably connected to the display panel 5, effectively constrains the vertical displacement of the movable frame 42 carrying the cleaning roller 8 along the surface of the display screen 6, ensuring smooth movement. In this design, the cleaning roller 8 can be installed by rolling as needed.

[0029] In a further specific embodiment based on the above, a first touch bar is installed at the bottom of the movable frame 42, and a first control button 25 cooperating with the first touch bar is fixedly installed at the bottom of the display panel 5. The first control button 25 is used to control the opening of the drain pipe 12 by being squeezed by the first touch bar; a second touch bar is installed at the top of the movable frame 42, and a second control button is correspondingly installed at the bottom of the water column 43. The second control button is used to control the closing of the drain pipe 12 by being squeezed by the second touch bar.

[0030] When in use, when the movable frame 42 slides down to the bottom of the display board 5, the first touch bar at the bottom of the movable frame 42 will contact and press the first control button 25 on the display board 5. When the first control button 25 is pressed, it will automatically control multiple drain pipes 12 to open, so that the multiple drain pipes 12 are connected. When the multiple drain pipes 12 are open, the water in the pressure box 44 will be discharged through the multiple drain pipes 12. When the water is discharged to the point that the overall weight of the pressure box 44 and the movable frame 42 is reduced, the reset spring rope 10 will gradually retract automatically and pull the movable frame 42 to move up and reset. When the movable frame 42 moves up to the point that the second touch bar contacts the second control button, the multiple drain pipes 12 will close. At this time, the pressure box 44 can wait for the next time to continue to fill with water, and then the movable frame 42 will move down again.

[0031] Thus, through the periodic water storage and drainage of the water pressure box 44, the moving frame 42 can be driven to move up and down on the display board 5, and during the movement, the cleaning roller 8 can be driven to clean the display screen 6, effectively keeping the surface of the display screen 6 clean and improving its display effect.

[0032] In the above scheme, the display screen 6 is used to display the analyzed data and has a touch function, enabling viewers to flexibly search for different data analysis tables. The cooperation between the support frame and the support column 15 enables the stable erection of the display board 5, effectively improving the support stability of the display board 5.

[0033] As attached Figure 6 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 and attached Figure 10 As shown, in another specific embodiment based on the above, the interior of the storage box 4 is divided into a dry chamber and a wet chamber by a vertical water-blocking plate 35. The wet chamber is further divided into an upper chamber and a lower chamber by a horizontal support plate 39. A servo motor 21 is installed in the dry chamber of the storage box 4. The output shaft of the servo motor 21 is connected to a drive roller 24. The drive roller 24 is rotatably and sealed through the lower chamber, and the portion located in the lower chamber is fixedly connected to a pushing column 40. A reciprocating arc-shaped groove is formed on the outer surface of the pushing column 40. A pressure plate 37 can also be slidably installed laterally in the lower chamber. The water plate 37 is in sealed contact with the four walls of the lower cavity. The side of the water pressure plate 37 near the push column 40 is provided with a push frame 41. The end of the push frame 41 away from the water pressure plate 37 is slidably set in the reciprocating arc groove. The lower cavity of the side of the water pressure plate 37 away from the push frame 41 is connected to the water storage column 43 through the water inlet pipe 13. The upper cavity of the storage box 4 is used to connect the rainwater collection component and is provided with an overflow outlet 20. The support plate 39 is provided with a drain pipe 38 connecting the upper cavity and the lower cavity. The drain pipe 38 is provided with a one-way valve that allows rainwater to flow from the upper cavity into the lower cavity.

[0034] In this way, after the rainwater is collected, the drive roller 24 driven by the servo motor 21 rotates the push column 40, and the reciprocating arc groove of the push column 40 drives the push frame 41 to carry the water pressure plate 37 to move back and forth, thereby absorbing the rainwater or air in the upper cavity and intermittently squeezing and transferring it to the water storage column 43 through the water supply pipe 13. At the same time, the overflow port 20 can be used to discharge excess rainwater to avoid backflow and overflow, and can also be connected to the atmosphere for air supply. In this solution, a one-way valve can be installed in the water supply pipe 13 as needed.

[0035] In a further specific embodiment based on the above, the upper cavity of the storage box 4 is also provided with a vertically arranged filter plate 36, the rain collection component is connected to the upper cavity on one side of the filter plate 36, the upper cavity on the other side of the filter plate 36 is connected to the lower cavity through the drain pipe 38, and the side wall of the upper cavity of the storage box 4 is also provided with an openable and closable impurity discharge opening.

[0036] In this way, the drain opening can be opened periodically to clean and remove impurities from the support plate 39 and filter plate 36. Specifically, rainwater in the drain column 22 falls onto the support plate 39 in the storage tank 4, and after being filtered by the filter plate 36, it falls into the lower cavity through the drain pipe 38, thus completing the filtration and conduction of rainwater. At this time, impurities in the rainwater are blocked by the filter plate 36, completing the filtration and removal of impurities. The filtered impurities can also be uniformly treated by the staff by opening the drain opening periodically.

[0037] As attached Figure 11 Appendix Figure 12 and attached Figure 13As shown, in a further specific embodiment based on the above, the rain collection component includes a rain collection disc 9, a water column 22, and a cutting blade 34. The upper end of the support column 15 is equipped with a rain collection disc 9 with an open upper end. The water column 22 is installed inside the support column 15. The bottom of the rain collection disc 9 is connected to the water inlet of the water column 22 through a water collection pipe 16 that passes through the support column 15. The water outlet of the water column 22 is connected to the upper cavity of the storage tank 4. The water column 22 is also equipped with a cutting blade 34 through a linkage roller 32. One end of the linkage roller 32 is sealed and rotatably passes through the water column 22 and the support column 15, and is fixedly sleeved with a linkage gear 33. A drive gear is fixedly sleeved on the drive roller 24 located in the dry cavity of the storage tank 4. The drive gear and the linkage gear 33 are connected by a transmission belt 23. The upper end of the storage tank 4 is provided with a hole through which the transmission belt 23 can pass.

[0038] Thus, during rainfall, rainwater and impurities fall into the rain collection tray 9 for automatic collection. The rainwater in the rain collection tray 9 is then conducted through the water collection pipe 16 to the drain column 22, where it flows downwards. At this time, the servo motor 21 can be activated to drive the drive roller 24 to rotate, which in turn drives the transmission belt 23. When the transmission belt 23 rotates, it drives the linkage gear 33 meshing with it to rotate. The rotation of the linkage gear 33 drives the linkage roller 32 to rotate, which in turn drives the cutting blades 34 on it to rotate, thereby cutting and crushing the impurities in the rainwater. At the same time, when the rainwater and impurities flow down in the drain column 22, the cutting blades 34 cut the rainwater and impurities, reducing the size of the impurities and preventing them from clogging the drain column 22 and other pipes due to excessive size, thus improving the rainwater collection efficiency. In this solution, a one-way valve can be installed in the water collection pipe 16 as needed. This solution can automatically collect rainwater when it rains, making it easy to clean the display screen 6 automatically without manual cleaning, resulting in better display effects. Moreover, using rainwater as the cleaning water source is lower in cost and more environmentally friendly.

[0039] As attached Figure 14 Appendix Figure 15 and attached Figure 16As shown, in a further specific embodiment based on the above, the energy storage unit includes a photovoltaic panel 7 for receiving sunlight and generating electricity, and an energy storage battery for energy storage. A mounting frame 17 is fixedly installed on one side of the support column 15. A laterally arranged angle-adjusting roller 19 is rotatably mounted on the mounting frame 17. Two steering brackets 18 are fixedly mounted on the angle-adjusting roller 19. The photovoltaic panel 7 is fixedly mounted on the two steering brackets 18. A driven gear 26 is also fixedly mounted on the angle-adjusting roller 19. A driven roller 28 is rotatably mounted inside the support column 15 and above the water column 22. A transmission gear is fixedly installed on the 8. The transmission gear, the driving gear, and the linkage gear 33 are connected by a transmission belt 23. The driven roller 28 is also provided with an electric self-locking wheel 29 for automatic control locking. A drive gear 30 is fixedly installed on the outside of the electric self-locking wheel 29. A transmission tooth plate 27 that can slide out of the support column 15 is movably installed inside the support column 15 and above the drive gear 30 through two telescopic limit rods 31. The transmission tooth plate 27 meshes with the drive gear 30 and the driven gear 26 respectively. The energy storage battery is installed inside the support column 15.

[0040] In the above scheme, the energy storage battery is used to store the electrical energy converted from solar energy received by the photovoltaic panel 7 and to power electrical components such as the display screen 6. During use, the servo motor 21 can be started as needed to drive the drive roller 24 to rotate. The rotation of the drive roller 24 will drive the drive gear on it to rotate, and through the meshing of the transmission belt 23, it will drive the transmission gear on the upper driven roller 28 to rotate, thereby driving the driven roller 28 to rotate synchronously. Prior to this, the electric self-locking wheel 29 can be pre-activated to lock it with the driven roller 28. When locked, the rotation of the driven roller 28 will drive the electric self-locking wheel 29 to rotate. When unlocked, the driven roller 28 and the electric self-locking wheel 29 are rotatably connected, and the rotation of the driven roller 28 will not drive the electric self-locking wheel 29 to rotate. When the electric self-locking wheel 29 rotates, it drives the external drive gear 30 to rotate. The rotation of the drive gear 30 pushes the transmission gear plate 27, which is meshed with it, to move under the constraint of the two telescopic limit rods 31. It also drives the driven gear 26, which is meshed with it, to rotate. In turn, it drives the angle adjustment roller 19 to rotate. When the angle adjustment roller 19 rotates, it drives the steering bracket 18 to rotate, which in turn drives the photovoltaic panel 7 to rotate. This allows the tilt angle of the photovoltaic panel 7 to be adjusted so that it can more easily receive sunlight for power generation and energy storage.

[0041] In this solution, photovoltaic panels 7 are used for energy storage and power supply to achieve energy conservation and emission reduction. The angle and position of photovoltaic panels 7 can be adjusted as needed to improve energy storage efficiency, increase the range of acceptable sunlight, effectively reduce dependence on external power sources, and are more energy-efficient and environmentally friendly.

[0042] Specifically, the electric self-locking wheel 29 can be started at a specified time through a preset program, and the servo motor 21 can rotate in the forward and reverse directions as needed, driving the adjustment roller 19 to rotate in the direction and angle of rotation. Then, the photovoltaic panel 7 is rotated to a preset angle suitable for sunlight through the steering bracket 18, thereby improving the effect of the photovoltaic panel 7 in receiving sunlight and improving its energy storage effect.

[0043] Specifically, when the drive roller 24 rotates forward, it drives the driven roller 28 to rotate forward. The forward rotation of the driven roller 28 drives the drive gear 30 to rotate, which in turn pushes the transmission gear plate 27 forward, thereby driving the angle-adjusting roller 19 to rotate and causing the photovoltaic panel 7 to deflect upward. When the drive roller 24 rotates in the reverse direction, the driven roller 28 and the drive gear 30 rotate in opposite directions, thereby driving the transmission gear plate 27 to move back, and causing the photovoltaic panel 7 to deflect downward back to its original position. Thus, the up-and-down deflection adjustment of the photovoltaic panel 7 can be achieved by the forward and reverse rotation of the drive roller 24 on the servo motor 21. When the electric self-locking wheel 29 is in the unlocked state, the drive of the servo motor 21 does not affect the movement of the photovoltaic panel 7.

[0044] In this solution, the aforementioned electric self-locking wheel 29 is an existing device. Its specific structure consists of an outer ring, multiple electric push rods, and a limiting ring. The limiting ring is rotatably sleeved on the outside of the drive roller 24 and is fixed to the outer ring. The multiple electric push rods are located inside the outer ring. Specifically, its working principle is as follows: The drive roller 24 has multiple positioning holes that cooperate with it. During automatic locking, the electric push rods are activated, causing their ends to move and engage with the positioning holes on the drive roller 24, thus completing the self-locking. At this time, the rotation of the drive roller 24 will drive the outer ring to rotate synchronously through the cooperation of the positioning holes and the electric push rods. Conversely, during unlocking, the rotation of the drive roller 24 will not drive the outer ring to rotate. This part is existing technology and will not be described in detail here.

[0045] In the above scheme, the storage box 4 can be equipped with an intelligent control panel 14 that works with the CNC computer as needed. The intelligent control panel 14 can be powered by a storage battery, and the display board 5 is mounted on the support column 15 via a support frame. The intelligent control panel 14 is used to actively control the start, stop or adjustment of components such as the servo motor 21, the electric self-locking wheel 29 and the drain pipe 12. The intelligent control panel 14 can also be used to receive the data analysis table uploaded by the CNC computer and transmit it to the display screen 6 for intelligent data analysis and display, and adjust the displayed data in the data analysis table in real time according to the changes in the transmitted data.

[0046] As attached Figure 17As shown, in another specific embodiment based on the above, a plurality of rotating disks are rotatably mounted on the bottom of the support base 1, and each rotating disk is provided with a universal caster wheel 2. The bottom of the support base 1 is also fixedly mounted with a support disk by a support spring. A plurality of support pads 3 are fixedly mounted on the lower end of the support disk. The upper end of the support disk is slidably connected to the support base 1 by a pressing rod. A locking plate is movably mounted on the upper part of the pressing rod, and a locking component for cooperating with the locking plate is fixedly mounted on the support base 1.

[0047] Thus, once the position of the support base 1 is adjusted, the locking plate can be pressed down to move the pressing rod downwards. When the pressing rod moves downwards, it will drive the support plate and multiple support pads 3 to move downwards as a whole until the multiple support pads 3 are pressed and adhered to the ground. Then, the locking plate is locked by the locking component to prevent it from moving further, thereby completing the positioning of the locking plate, the pressing rod and the multiple support pads 3, and providing bottom support for the support base 1, making it unable to move, thus effectively improving the support stability of this display rack. With the setting of the universal casters 2, the movement and positioning of the support base 1 can be realized, and the position of the display board 5 can be conveniently adjusted.

[0048] One method of use, applied to the aforementioned data display rack, includes the following steps: The data to be displayed is transmitted to the intelligent control panel 14 via a CNC computer, and the data analysis table is transmitted to the display screen 6 via the intelligent control panel 14 for data display. The photovoltaic panel 7 of the energy storage unit receives sunlight and generates electricity to supply power. The rain collection component collects rainwater and stores it in the storage box 4 when it rains. Then, the storage box 4 is controlled to supply water to the water column 43. The water column 43 supplies water to the pressure box 44, which is open at the top, to increase the water storage capacity in the pressure box 44. When the pressure box 44 moves downward due to its own weight, the reset spring rope 10 is stretched and drives the cleaning roller 8 on it to move downward synchronously. When the cleaning roller 8 moves, it will clean the surface of the display screen 6. When the pressure box 44 and the cleaning roller 8 move to the bottom of the display screen 6, the drain pipe 12 on the pressure box 44 is opened to drain water. The weight of the pressure box 44 decreases and it is driven upward by the reset spring rope 10 to reset, thus completing one cleaning operation.

[0049] Specifically: During rainfall, the water stored in the pressure box 44 is actively supplied by the storage tank 4, increasing the overall weight of the pressure box 44. The pressure box 44, along with the cleaning roller 8, moves downward along the surface of the display screen 6 to clean, and the reset spring rope 10 is stretched accordingly. During the movement of the pressure box 44, rainwater can be poured in to further increase the water stored in the pressure box 44, or the storage tank 4 can continue to supply water to ensure that the pressure box 44 can move to the bottom of the display screen 6. At the same time, excess rainwater can overflow from the opening at the top of the pressure box 44. Afterward, the drain pipe 12 drains water in a controlled manner, and the reset spring rope 10 drives the pressure box 44, along with the cleaning roller 8, to reset upward. When the rainfall is heavy, the water stored in the pressure box 44 can also be directly poured in by rainwater, passively increasing the water stored and moving downward. Afterward, the drain pipe 12 drains water in a controlled manner, and the reset spring rope 10 drives the reset.

[0050] When there is no rainfall, the water stored in the pressure box 44 is actively supplied by the storage box 4 to increase the overall weight of the pressure box 44. The pressure box 44, carrying the cleaning roller 8, moves downward along the surface of the display screen 6 to clean, and the reset spring rope 10 is stretched accordingly. During this process, the water column 43 can continue to spray water into the pressure box 44, which has an open top, to increase the water storage and ensure that the pressure box 44 can move to the bottom of the display screen 6. At the same time, excess rainwater can overflow from the open top of the pressure box 44. After that, the drain pipe 12 drains water in a controlled manner, and the reset spring rope 10 drives the pressure box 44, carrying the cleaning roller 8, to reset upward.
