They not only have the characteristics of high brightness and high resolution, but also can adapt to various complex environments, becoming an ideal medium for business publicity, government announcements and public information release, adding color and vitality to urban life.

[0003] When the waterproof energy-saving protection device of the outdoor display screen is working, firstly, high-level waterproof materials such as waterproof sealing rings and waterproof coatings are used to fully cover the interfaces and gaps of the display screen to ensure that rainwater cannot penetrate. Secondly, the intelligent temperature control system is used to adjust the working temperature of the display screen, which can avoid overheating and adapt to outdoor temperature changes to achieve energy-saving effects.

[0004] However, the existing waterproof and energy-saving protection device of the outdoor display screen only seals the various interfaces and gaps of the display screen more tightly.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1: Figures 1 to 9As shown, a waterproof energy-saving protection device for a display screen according to an embodiment of the present invention comprises a protective shell 1, an outdoor screen 2 is fixedly connected to the protective shell 1, a wiping assembly is arranged in the protective shell 1, the wiping assembly comprises a motor 11, a support plate 12 is arranged at a position of the protective shell 1 corresponding to the motor 11, the support plate 12 is used to support the motor 11, a reciprocating screw 13 is fixedly connected to the output end of the motor 11, a sliding block 111 is slidably connected to the circumferential surface of the reciprocating screw 13, and a limiting member is arranged at a position corresponding to the sliding block 111 on both sides of the protective shell 1, and the limiting member The parts are used to limit the sliding block 111; the bottom end of the reciprocating screw 13 is connected to the transmission belt 114, and the reciprocating screw 13 is connected to another reciprocating screw 13 through the transmission belt 114. The two reciprocating screws 13 are both slidably connected to the sliding block 111, and the two sliding blocks 111 are clamped with the same sponge block 17, which can wipe the surface of the outdoor screen 2; the top of the protective shell 1 is provided with an extrusion component, which can absorb the moisture in the sponge block 17 so that the sponge block 17 can always maintain a certain suction force.

[0039] Specifically, the existing waterproof and energy-saving protection device for outdoor display screens only seals the interfaces and gaps of the display screen more tightly. However, in actual use, because there is a lot of dust floating in the outside air, and because the display screen will generate static electricity on the screen surface during long-term use, and static electricity has the property of attracting light and small objects, it will adsorb the surrounding dust particles to the screen surface. When it rains, rainwater may carry dust and penetrate into the interior of the display screen, causing circuit short circuit and lamp bead damage.

[0040] Therefore, the present invention solves this problem by setting a certain structure. First, the motor 11 in the device drives the reciprocating screw 13 to rotate, and the sliding block 111 slides on the circumferential surface of the reciprocating screw 13 and is constrained by the limiters on both sides, ensuring a stable reciprocating motion trajectory. This motion is transmitted to the other reciprocating screw 13 through the transmission belt 114, so that the two sliding blocks 111 move synchronously and along the reciprocating screw 13. The sponge block 17 they are jointly engaged can therefore evenly wipe the surface of the outdoor screen 2 to effectively remove dust and water stains. The extrusion component on the top of the protective shell 1 plays a role in adjusting the humidity of the sponge block 17. By applying pressure to the sponge block 17 regularly or as needed to discharge excess water, it is ensured that the sponge block 17 is appropriately wet during wiping to enhance the cleaning effect, and the risk of short circuit caused by excessive water is avoided, thereby achieving dual protection of energy saving and safety, improving the cleaning efficiency and maintenance convenience of the outdoor display screen, and reducing the cost and frequency of manual cleaning.

[0041] This solves the problem that rainwater may penetrate into the outdoor display screen, causing circuit short circuit or lamp bead damage.

[0042] like Figure 6 and Figure 7 As shown, in this embodiment, a card slot 122 is provided on one side of each sliding block 111, and a fixed block 119 can be clamped in the card slot 122. The fixed block 119 is fixedly connected to the sponge block 17. A groove 124 is provided on one side of the fixed block 119. A first slot body 118 is provided on the upper surface of the sliding block 111. Two springs 121 are fixedly connected to the upper surface of the first slot body 118. The upper ends of the two springs 121 are fixedly connected to the same top plate 120, and a protrusion 123 is fixedly connected to the lower surface of the top plate 120.

[0043] Specifically, the sliding block 111 is engaged with the fixing block 119 through the card slot 122, and the fixing block 119 is connected to the sponge block 17 to achieve the fixed installation of the sponge block 17. A spring 121 and a top plate 120 are arranged in the first groove body 118 on the sliding block 111. The protrusion 123 on the lower surface of the top plate 120 can push the spring 121 under the extrusion force of the fixing block 119. When the protrusion 123 is stuck in the groove 124, the spring 121 also completes automatic reset. The protrusion 123 is pushed into the groove 124 by the resilience of the spring 121, thereby locking the position of the sliding block 111 and the fixing block 119, ensuring that the sponge block 17 is stable and does not fall off, which is convenient for the quick installation and removal and replacement of the sponge block 17; the spring 121 and the protrusion 123 have a good locking function, which enhances the stability and reliability of the connection, and is easy to operate, thereby improving work efficiency and convenience of use.

[0044] like Figure 6 and Figure 7 As shown, after the fixed block 119 of this embodiment slides along the card slot 122 into the interior of the sliding block 111, the groove 124 on one side of the fixed block 119 will first squeeze the top block, thereby lifting the top plate 120 upward, so that the top plate 120 drives the spring 121 upward to deform, and then when the top block gradually enters the groove 124, it will gradually move downward. At this time, under the action of the restoring force of the spring 121, the top block is inserted into the groove 124, completing the card connection between the fixed block 119 and the top block, and fixing the sponge block 17.

[0045] Specifically, when the fixed block 119 slides into the sliding block 111 along the card slot 122, the groove 124 on its side first squeezes the top block on the top plate 120, causing the top plate 120 to rise and compress the spring 121. As the fixed block 119 continues to slide, the top block gradually enters the groove 124, and the spring 121 pushes the top plate 120 downward under the action of the restoring force, and the top block is then inserted into the groove 124, realizing the card connection between the fixed block 119 and the sliding block 111, thereby firmly fixing the sponge block 17. Its beneficial effect is that through the elastic deformation and recovery of the spring 121, the automatic card connection and locking of the fixed block 119 and the sliding block 111 are realized, the operation is simple and the fixing effect is reliable. At the same time, this design facilitates the rapid installation and disassembly of the sponge block 17, thereby improving work efficiency and convenience of use.

[0046] like Figure 2 and Figure 6 As shown, the limiting member of this embodiment includes limiting plates 112 fixedly connected to both sides of the inner wall of the protective shell 1, a limiting groove 113 is provided on one side of each limiting plate 112, a limiting block 117 is fixedly connected to one side of each sliding block 111, and each limiting block 117 can slide along the limiting groove 113.

[0047] Specifically, the sliding block 111 slides along the limiting groove 113 on the limiting plate 112 on the inner wall of the protective shell 1 through the limiting block 117, ensuring that the sliding block 111 moves stably on a specific path, improving the operating stability and accuracy of the sliding block 111, effectively preventing the sliding block 111 from deflecting or shaking during movement, and enhancing the stability and reliability of the overall structure.

[0048] Embodiment 2: Figures 1 to 9 As shown, compared with Example 1, another embodiment of the present invention is: the extrusion assembly includes a connecting plate 14 slidably arranged inside the fixed shell, a connecting box 16 is fixedly connected to one side of the connecting plate 14, a first hydraulic cylinder 18 is fixedly connected to one side of the connecting plate 14, a second hydraulic cylinder 110 is fixedly connected to the top end of the protective shell 1, and an extrusion plate 19 is fixedly connected to the output end of the second hydraulic cylinder 110, and the cross-section of the extrusion plate 19 is the same as the cross-section of the sponge block 17.

[0049] Specifically, the first hydraulic cylinder 18 drives the connecting plate 14 and the connecting box 16 fixed thereto to slide inside the fixed shell to adjust a specific position until it moves to just below the sponge block 17. At the same time, the output end of the second hydraulic cylinder 110 drives the squeezing plate 19 to move downward to squeeze the sponge block 17 placed in the protective shell 1. Since the cross-section of the squeezing plate 19 is the same as that of the sponge block 17, the uniformity and accuracy of the squeezing are ensured, and the water in the sponge block 17 is squeezed, thereby changing the humidity of the sponge block 17, improving the wiping effect, and preventing the sponge block 17 from having too much moisture.

[0050] like Figure 5 As shown, a plurality of positioning holes 15 are provided on the upper surface of the connection box 16 of this embodiment. When the squeezing plate 19 squeezes the sponge block 17 , water squeezed out will flow into the positioning holes 15 and be collected by the connection box 16 .

[0051] Specifically, when the extrusion plate 19 squeezes the sponge block 17, the squeezed water will flow into the positioning hole 15 on the upper surface of the connection box 16, and then be collected by the connection box 16, effectively avoiding the escape of water during the squeezing process and preventing the water from wetting the outdoor screen 2 again. At the same time, the collection function of the connection box 16 facilitates the subsequent unified treatment and discharge of water, thereby improving the convenience and environmental protection of operation.

[0052] like Figure 3 and Figure 4 As shown, an extrusion groove 115 is provided inside the protective shell 1 of this embodiment. The cross section of the extrusion groove 115 is trapezoidal. A guide groove 116 is provided inside the protective shell 1 at a position corresponding to the extrusion groove 115. The guide groove 116 is used to guide falling rainwater.

[0053] Specifically, when the sponge block 17 absorbs too much water, its adsorption force will decrease, and then the wiped water will flow downward. The setting of the guide groove 116 can guide the rainwater sliding down from the sponge block 17 to squeeze the groove 115 and flow to the guide groove 116. The guide groove 116 effectively avoids the accumulation of rainwater, keeps the inside of the protective shell 1 dry and clean, and improves the durability and use effect of the equipment.

[0054] like Figure 8 and Fig. 9 As shown, a guide frame 4 is fixedly connected to one side of the protective shell 1 of this embodiment, a collecting groove 45 is opened in the guide frame 4, a connecting pipe 42 is fixedly connected to one side of the guide frame 4, and a storage box 41 is fixedly connected below the connecting pipe 42, and the storage box 41 is used to collect rainwater.

[0055] Specifically, the collecting groove 45 in the guide frame 4 is used to receive the rainwater flowing out from the guide groove 116 of the protective shell 1. The rainwater then flows into the storage box 41 below through the connecting pipe 42 for centralized collection, thereby realizing the orderly collection and discharge of rainwater, avoiding the random flow of rainwater and the possible environmental pollution. At the same time, it also provides convenience for the reuse of rainwater, reflecting the environmental protection and practicality of the design.

[0056] like Fig. 9 As shown, in this embodiment, two injection holes 46 are opened on one side of the connecting pipe 42 corresponding to the guide frame 4, and rainwater flows into the storage box 41 from the injection holes 46. An electric guide rail 43 is fixedly connected to one side of the connecting pipe 42, and a sealing plate 44 is slidably connected inside the electric guide rail 43. The sealing plate 44 is used to seal the injection hole 46.

[0057] Specifically, rainwater flows into the storage box 41 through the injection hole 46 on the connecting pipe 42, and the electric guide rail 43 drives the sealing plate 44 to slide in the connecting pipe 42 to open or seal the injection hole 46. The design of the electric guide rail 43 and the sealing plate 44 can flexibly control the inflow of rainwater as needed, which not only ensures the efficiency of rainwater collection, but also effectively prevents the leakage of rainwater when not needed, thereby improving the controllability and practicality of the rainwater collection system.

[0058] like Figure 8As shown, one side of the storage box 41 of this embodiment is fixedly connected to a limit tube 410, one side of the limit tube 410 is fixedly connected to a jet pump 47, one side of the jet pump 47 is fixedly connected to a positioning tube 48, both sides of the positioning tube 48 are fixedly connected to a nozzle 49, a plurality of small spray holes are opened on the circumferential surface of the nozzle 49, the nozzle 49 is used to spray water mist to reduce dust around the outdoor screen 2, and can cool down in hot weather, and a protective cover 3 is fixedly connected to the top of the protective shell 1, and the protective cover 3 is used to protect the jet pump 47.

[0059] Specifically, rainwater in the storage box 41 flows into the jet pump 47 through the limit pipe 410. The jet pump 47 transports the water to the positioning pipe 48 after pressurization, and then sprays it out in the form of fine water mist through the nozzles 49 on both sides of the positioning pipe 48. The fine spray holes opened on the circumferential surface of the nozzle 49 ensure the uniform distribution of the water mist, which can be used to reduce dust around the outdoor screen 2 and also play a cooling role in hot weather. The protective cover 3 on the top of the protective shell 1 effectively protects the jet pump 47 from interference and damage from the external environment. The design makes full use of rainwater resources. Through the cooperation of the jet pump 47 and the nozzle 49, the uniform spraying of water mist is achieved, which not only meets the dust reduction needs of the environment around the outdoor screen 2, but also provides an effective cooling effect in hot weather, thereby improving the comfort and service life of the outdoor screen 2. At the same time, the design of the protective cover 3 protects the normal operation of the jet pump 47, reduces equipment failures and maintenance costs caused by environmental factors, and the overall design embodies the concepts of environmental protection, energy saving and practicality.

[0060] Working principle: first, the motor 11 in the device drives the reciprocating screw 13 to rotate, and the sliding block 111 slides on the circumferential surface of the reciprocating screw 13 and is constrained by the limiters on both sides, ensuring a stable reciprocating motion trajectory. This motion is transmitted to the other reciprocating screw 13 through the transmission belt 114, so that the two sliding blocks 111 move synchronously along the reciprocating screw 13, and the sponge block 17 they are jointly connected to can therefore evenly wipe the surface of the outdoor screen 2. The specific connection is that the sliding block 111 is connected to the fixed block 119 through the card slot 122, and the fixed block 119 and the sponge block 17 The first groove 118 on the sliding block 111 is connected to realize the fixed installation of the sponge block 17. The spring 121 and the top plate 120 are arranged in the first groove 118 on the sliding block 111. The protrusion 123 on the lower surface of the top plate 120 can push the spring 121 under the extrusion force of the fixed block 119. When the protrusion 123 is stuck in the groove 124, the spring 121 also completes automatic reset. The protrusion 123 is pushed into the groove 124 by the resilience of the spring 121, thereby locking the position of the sliding block 111 and the fixed block 119, ensuring that the sponge block 17 is stable and does not fall off, which is convenient for the rapid installation, disassembly and replacement of the sponge block 17;

[0061] The sponge block 17 effectively removes dust and water stains when wiping the outdoor screen 2, and the squeezing component on the top of the protective shell 1 plays a role in adjusting the humidity of the sponge block 17. By applying pressure to the sponge block 17 regularly or as needed, excess water is discharged, which not only ensures that the sponge block 17 is properly moistened during wiping to enhance the cleaning effect, but also avoids the risk of short circuit caused by excessive moisture, thereby achieving dual protection of energy saving and safety, improving the cleaning efficiency and maintenance convenience of the outdoor display screen, and reducing the cost and frequency of manual cleaning;

[0062] In addition, the first hydraulic cylinder 18 drives the connecting plate 14 and the connecting box 16 fixed thereto to slide inside the fixed shell to adjust a specific position until the connecting plate 14 moves to the position directly below the sponge block 17. At the same time, the output end of the second hydraulic cylinder 110 drives the squeezing plate 19 to move downward to squeeze the sponge block 17 placed inside the protective shell 1. Since the cross section of the squeezing plate 19 is the same as that of the sponge block 17, the uniformity and accuracy of the squeezing are ensured, and the water in the sponge block 17 is squeezed, thereby changing the humidity of the sponge block 17, improving the wiping effect, and preventing the sponge block 17 from being too wet.

[0063] In addition, when the sponge block 17 absorbs too much water, its adsorption force will decrease, and then the wiped water will flow downward. The setting of the guide groove 116 can guide the rainwater sliding off the sponge block 17 to squeeze the groove 115 and flow to the guide groove 116, and the guide groove 116 effectively avoids the accumulation of rainwater, keeps the inside of the protective shell 1 dry and clean, and improves the durability and use effect of the equipment; the collection groove 45 in the guide frame 4 is used to receive the rainwater flowing out of the guide groove 116 of the protective shell 1, and then the rainwater flows into the storage box 41 below through the connecting pipe 42 for centralized collection, realizing the orderly collection and discharge of rainwater, avoiding the random flow of rainwater and the possible environmental pollution, and at the same time, it also provides convenience for the reuse of rainwater, reflecting the environmental protection and practicality of the design;

[0064] Finally, rainwater flows into the storage box 41 through the injection hole 46 on the connecting pipe 42, and the rainwater in the storage box 41 flows into the jet pump 47 through the limit pipe 410. The jet pump 47 conveys the water to the positioning pipe 48 after pressurization, and then sprays it out in the form of fine water mist through the nozzles 49 on both sides of the positioning pipe 48. The fine spray holes opened on the circumferential surface of the nozzle 49 ensure the uniform distribution of the water mist, which can be used to reduce dust around the outdoor screen 2, and can also play a cooling role in hot weather. The protective cover 3 on the top of the protective shell 1 effectively protects the jet pump 47 from interference and damage from the external environment. The design makes full use of rainwater resources. Through the cooperation of the jet pump 47 and the nozzle 49, the uniform spraying of water mist is achieved, which not only meets the dust reduction needs of the environment around the outdoor screen 2, but also provides an effective cooling effect in hot weather, thereby improving the comfort and service life of the outdoor screen 2. At the same time, the design of the protective cover 3 protects the normal operation of the jet pump 47, reduces equipment failures and maintenance costs caused by environmental factors, and the overall design embodies the concepts of environmental protection, energy saving and practicality.
