Description

Technical Field

[0001] This application relates to the field of waterproof technology, and particularly to a waterproof device and method for front maintenance of outdoor modules. Background Art

[0002] Outdoor LED displays have the advantages of high brightness, long lifespan, etc., and have been widely applied in various fields. However, most of the LED modules installed outdoors are installed and maintained in a rear maintenance manner, which is relatively troublesome compared to the magnet-based installation and maintenance of indoor modules. For outdoor LED modules compared to indoor modules, they require additional dust and waterproof designs. If rainwater enters the interior along the modules, it will damage the LED modules, power supplies, and signal parts. Therefore, there is an urgent need for a waterproof method for front maintenance of outdoor modules, which can optimize the current disadvantages of inconvenient front maintenance and ensure the dust and waterproof level requirements outdoors. Summary of the Invention

[0003] To solve the above problems, this application proposes a waterproof device for front maintenance of outdoor modules. The device includes an outdoor waterproof module and a waterproof mechanism; The outdoor waterproof modules are spliced and fixed, and there are gaps between the outdoor waterproof modules; The waterproof mechanism is connected to the outdoor waterproof module. The waterproof mechanism includes a main frame and a waterproof eaves structure provided on the main frame. The waterproof eaves structure corresponds to the interfaces provided on the outdoor waterproof module and is used to waterproof the interfaces; The main frame is rectangular, and a diversion slope is provided on the outer side of the edge of the main frame. The diversion slope has a trapezoidal notch structure. When rainwater flows in along the gap, a diversion port for rainwater to flow out is formed through the trapezoidal notch between the diversion slopes.

[0004] Connect the waterproof mechanism to the outdoor waterproof module. On the basis of the splicing and fixing of the outdoor waterproof modules, make the main frame and the waterproof eaves structure of the waterproof mechanism correspond to the interfaces, which does not affect the front maintenance operation and optimizes the convenience of front maintenance. Secondly, in terms of waterproofing, the waterproof eaves mechanism covers the interfaces on the outdoor waterproof module through the eaves structure, which can comprehensively protect the interfaces from rain damage. Moreover, the trapezoidal notch-shaped diversion slopes provided on the outer side of the edge of the main frame effectively increase the contact area of rainwater. The diversion ports formed by the trapezoidal notches of the diversion slopes can quickly direct the rainwater seeping through the gap to the outside of the device, avoiding the accumulation and backflow of rainwater around the main frame, effectively blocking the rainwater from entering the interfaces and the interior of the module, and cooperating with the waterproof eaves structure to further improve the waterproof performance of the outdoor module.

[0005] In one implementation of the present application, the waterproof eaves structure extends in a direction away from the outdoor waterproof module to form a waterproof inclined plane. There is a gap between the bottom of the waterproof inclined plane and the interface. The waterproof inclined plane is used to waterproof the interface and guide rainwater to drain outwards of the waterproof mechanism along its inclined direction.

[0006] The waterproof eaves structure can not only provide waterproof protection for the interface from all directions. The waterproof inclined plane formed by extending in the direction away from the module can also, when rainwater flows out along the module gap, use the inclined direction of the inclined plane to guide the rainwater to drain outwards of the waterproof mechanism. Moreover, there is a gap between the bottom of the waterproof inclined plane and the interface, which can protect the outdoor module from rain damage, improving the reliability and service life of the outdoor LED display screen.

[0007] In one implementation of the present application, the device further includes copper posts; A number of first fixing holes are provided on the main frame. One end of the copper post with an external thread passes through the first fixing holes and is connected to the outdoor waterproof module. The copper post is used to fix the outdoor waterproof module and the waterproof mechanism.

[0008] One end of the copper post with an external thread passes through the first fixing holes of the main frame and is connected to the outdoor waterproof module. By means of threaded fastening, not only the fixation of the waterproof mechanism and the outdoor waterproof module is realized, avoiding loosening and displacement of components due to outdoor environmental factors and affecting the waterproof performance, but also during the front maintenance operation, the firm connection of each component can be ensured, guaranteeing the integrity of the overall structure during the maintenance process.

[0009] In one implementation of the present application, the device further includes a waterproof rubber ring; A waterproof rubber ring is provided between the outdoor waterproof module and the waterproof mechanism. A number of second fixing holes corresponding to the first fixing holes are provided on the waterproof rubber ring. The waterproof rubber ring waterproofs the outdoor waterproof module under the fixing action of the copper posts passing through the second fixing holes.

[0010] The waterproof rubber ring is filled between the outdoor waterproof module and the waterproof mechanism, effectively filling the possible gaps at the splicing part of the two, and cooperating with the waterproof eaves structure to form multiple waterproof barriers, further blocking the possibility of rainwater infiltration along the module gap.

[0011] In one implementation of the present application, the device further includes a strong magnet. The strong magnet is embedded in the other end of the copper post with an internal thread, and is used to adsorb the device to an external steel structure to realize the front maintenance of the outdoor waterproof module.

[0012] In one implementation of the present application, the waterproof eaves structure includes a first waterproof eaves structure and a second waterproof eaves structure. The first waterproof eaves structure is used to protect the power interface in the outdoor waterproof module, and the second waterproof eaves structure is used to protect the signal interface in the outdoor waterproof module.

[0013] In one implementation of the present application, the waterproof mechanism is made of sheet metal.

[0014] In one implementation of the present application, the strong magnet adjusts the flatness of the display screen formed by the outdoor waterproof module by adjusting the degree of screwing out between the strong magnet and the copper column.

[0015] By adjusting the degree of screwing out between the strong magnet and the copper column, it is possible to finely adjust the unevenness generated after the outdoor waterproof modules are spliced, improve the installation efficiency, and reduce the complexity of the traditional calibration process. In addition, by adjusting the degree of screwing out, it can ensure that the surface of the display screen formed by the outdoor waterproof module is flat and uniform, effectively avoiding problems such as display screen deformation and color unevenness caused by module misalignment, and improving the display effect and visual perception.

[0016] The embodiment of the present application provides a waterproof method for front maintenance of an outdoor display module, which is applied to a waterproof device for front maintenance of an outdoor display module as described in any one of the above. The device includes an outdoor waterproof module and a waterproof mechanism. The method includes: When the outdoor waterproof module is flooded, through the waterproof slope formed by the waterproof eaves structure provided on the waterproof mechanism, along the inclination direction of the waterproof slope, the rainwater flowing in through the gap of the outdoor waterproof module is discharged to the outside of the waterproof mechanism.

[0017] In one implementation of the present application, the method further includes: Collect the pressure signal formed by the rainwater flowing into the diversion port through the pressure sensor provided below the diversion port, and determine the instantaneous inflow rate of the rainwater according to the pressure signal; Generate an inflow rate curve corresponding to the outdoor waterproof module according to the instantaneous inflow rates at different times, and send a warning signal to the controller according to the trend change of the inflow rate curve to perform water accumulation warning through the warning signal.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Apparently, the described embodiments are only a part rather than all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] In addition, in the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0021] In the present application, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0022] Such as Figure 1As shown in the figure, an embodiment of the present application provides a waterproof device for front maintenance of outdoor modules. The device includes an outdoor waterproof module 1 and a waterproof mechanism 3. The outdoor waterproof module 1 refers to a standardized component unit specifically designed for complex outdoor environments, usually composed of structures such as a high-strength engineering plastic housing, a waterproof breathable membrane, and a sealing ring slot. The outdoor waterproof module 1 has completed basic waterproof treatment before leaving the factory and can independently protect internal electronic components or mechanical structures. Each outdoor waterproof module 1 serves as an outdoor LED display unit and is fixed together by splicing to finally form a complete outdoor LED display. There are gaps between the outdoor waterproof modules 1. When it rains, rainwater will seep in through the gaps and may flow into the inside of the module, thereby damaging interfaces, internal components, etc. in the module. To reduce the damage caused by rainwater seepage to the outdoor waterproof module 1, the device is provided with a waterproof mechanism 3 connected to the outdoor waterproof module 1. The waterproof mechanism 3 is made of sheet metal material and has high strength and the ability to resist deformation, ensuring the long-term reliability of the waterproof performance. As Figure 2 shown, the waterproof mechanism 3 includes a main frame 31 and a waterproof eaves structure 32 provided on the main frame. A copper column 4 is provided in the device, and the copper column 4 is used to fix the outdoor waterproof module 1 and the waterproof mechanism 3. As Figure 1 and Figure 2 shown, a number of first fixing holes 33 are provided on the main frame 31. One end of the copper column 4 has an external thread and the other end has an internal thread. The end of the copper column 4 with the external thread can pass through the first fixing hole 33 to connect and fix the waterproof mechanism 3 and the outdoor waterproof module 1.

[0023] Since the outdoor waterproof module 1 and the waterproof mechanism 3 are fixed together, the waterproof eaves structure 32 corresponds to the interfaces provided on the outdoor waterproof module 1. The waterproof eaves structure 32 includes a first waterproof eaves structure 321 and a second waterproof eaves structure 322. The first waterproof eaves structure 321 and the second waterproof eaves structure 322 are respectively used to protect the power interface ( Figures 1-3 not shown in the figure) and the signal interface ( Figures 1-3 not shown in the figure) in the outdoor waterproof module 1. The eaves-shaped protrusion formed by the waterproof eaves structure 322 can completely cover the interfaces, thereby protecting the interfaces from being damaged by rainwater when it rains. At the same time, as Figure 2 and Figure 3As shown in the figure, the main frame 3 is rectangular, and a diversion inclined surface 34 is provided on the outer side of the four peripheral edges of the main frame 3. The diversion inclined surface 34 has a trapezoidal notch structure. The height and width of the diversion inclined surface 34 do not exceed the height and width of the outdoor waterproof module, which is convenient for front maintenance. The diversion inclined surfaces 34 provided on different main frames 3 will form a diversion port 35 for rainwater to flow out through the trapezoidal notch structure due to the splicing of the outdoor waterproof modules 1. Based on this setting, rainwater will no longer accumulate in the gaps between the outdoor waterproof modules 1 and gradually penetrate into the module interior, but will discharge the inflowing rainwater along the diversion port 35, avoiding the risk of rainwater infiltration.

[0024] In one embodiment, the waterproof eaves structure 3 extends in a direction away from the outdoor waterproof module 1 to form a waterproof inclined surface. The waterproof inclined surface is convex, and there is a gap between its bottom and the interface provided in the outdoor waterproof module 1. In this way, when rainwater flows in along the gap, the rainwater will flow down along the inclined direction of the waterproof inclined surface and discharge to the outside of the waterproof mechanism 3. The rainwater can flow out through the gap and discharge along the inclined surface formed by the waterproof eaves structure 32, protecting the outdoor waterproof module 1 from being damaged by rainwater. Moreover, the convex formed by the waterproof eaves structure 32 can protect the interface on the outdoor waterproof module 1 from being damaged by rainwater, realizing all-round waterproof protection for the interface.

[0025] In one embodiment, as Figure 1 shown, a waterproof rubber ring 2 is also provided in the device. The waterproof rubber ring 2 has a structure similar to that of the main frame 3, and is provided with a number of second fixing holes 21 corresponding to the first fixing holes 33. The positions of the second fixing holes 21 and the first fixing holes 33 are corresponding. The copper column 4 can sequentially pass through the first fixing hole 33 and the second fixing hole 21 to fix the main frame 3, the waterproof rubber ring 2 and the outdoor waterproof module 1. The copper column 4, as an intermediate member, fastens the outdoor waterproof module 1 and the waterproof mechanism 3, so that the waterproof rubber ring 2 provided between the outdoor waterproof module 1 and the waterproof mechanism 3 plays a waterproof role, fills the gap between the outdoor waterproof module 1 and the waterproof mechanism 3, and blocks the possibility of rainwater further penetrating through the intermediate gap.

[0026] In one embodiment, as Figure 1 and Figure 3As shown in the figure, the device is also provided with a strong magnet 5, which is arranged in cooperation with the copper column 4 and includes an external thread structure matching the internal thread of the copper column 4. It can be embedded into the other end of the copper column 4 with internal threads. By controlling the tightening degree between the strong magnet 5 and the copper column 4, the strong magnet 5 can be fixed between the outdoor waterproof module 1 and the waterproof mechanism 3. The strong magnet 5 can adsorb the waterproof device on the external steel structure through its magnetic attraction characteristics, so as to realize the front maintenance of the outdoor waterproof module 1. Traditional outdoor display screens use screws to fix the modules from the back. During maintenance, the external protection structure needs to be disassembled first, which may damage the protection structure of the outdoor module. However, in the embodiment of the present application, a strong magnet is used, which can form a rigid connection that can be disassembled repeatedly between the outdoor waterproof module and the steel structure carrier without affecting the original waterproof performance, taking into account both installation reliability and maintenance convenience.

[0027] In one embodiment, the strong magnet 5 is connected to the copper column 4 through internal threads. By adjusting the thread engagement length with the copper column 4, the screwing-out degree between the strong magnet 5 and the copper column 4 can be controlled, and then the protruding height of the strong magnet 5 can be adjusted. The protruding height of one strong magnet 5 determines the position of one outdoor waterproof module 1. The flatness of the entire LED outdoor display screen can be adjusted by the protruding height of the strong magnet 5. If some outdoor waterproof modules 1 are uneven, only by adjusting the screwing-out degree of the strong magnet 5 arranged behind the outdoor waterproof module 1, the position of the outdoor waterproof module 1 can be finely adjusted, reducing the operation complexity.

[0028] According to Figure 3 As shown in the schematic diagram of a waterproof process, when rainwater flows towards the outdoor waterproof module along the IN direction, the rainwater will enter the side where the rear waterproof mechanism is located along the gap, and the water flow will flow to the diversion port 35 and be discharged outward along the OUT direction from the diversion port 35. At the same time, part of the water flow will also flow out of the waterproof mechanism along the waterproof slope under the action of gravity.

[0029] The above is the device embodiment proposed in the present application. Based on the same idea, some embodiments of the present application also provide the method corresponding to the above device.

[0030] Figure 4 This is a schematic flow chart of a waterproof method for front maintenance of an outdoor display module provided by an embodiment of the present application. As Figure 4 shown, it is applied to a waterproof device for front maintenance of an outdoor display module as described in any one of the above. The device includes an outdoor waterproof module and a waterproof mechanism. The method includes: S401: In the case of water ingress into the outdoor waterproof module, through the waterproof slope formed by the waterproof eaves structure arranged on the waterproof mechanism, along the inclination direction of the waterproof slope, the rainwater flowing in through the gap of the outdoor waterproof module is discharged to the outside of the waterproof mechanism.

[0031] In one embodiment, a pressure sensor (not shown in Figures 1-3 ) is further provided below the diversion opening. The pressure sensor can be used to collect the pressure signal formed by the rainwater flowing into the diversion opening, and determine the instantaneous inflow rate corresponding to the rainwater according to the pressure signal. In this way, the controller can generate an inflow rate curve corresponding to the outdoor waterproof module according to the instantaneous inflow rate detected at different times. The trend of the inflow rate curve can reflect the change of the rainwater flow rate flowing into the outdoor waterproof module at present. According to the change of this trend, it can be judged whether the current rain intensity is gradually increasing. When the inflow rate is greater than the warning threshold, or the trend change is greater than the preset threshold, it indicates that there is a risk of water accumulation in the current outdoor module. At this time, a corresponding warning signal needs to be generated to give a water accumulation warning to the monitoring center. By real-time detecting the change of the rainwater inflow rate, the real-time monitoring and accurate warning of the water accumulation risk of the outdoor waterproof module can be realized, effectively improving the waterproof safety.

[0032] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the differences between each embodiment and other embodiments are emphasized. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can refer to the description of the method embodiment.

[0033] The above description is only for the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
