Description

Technical Field

[0001] The utility model relates to the technical field of waterproof boxes, and in particular to a special waterproof box for an LED guide screen on a platform of a passenger station. Background Art

[0002] In railway passenger stations, LED guide screens are primarily used to centrally display train arrival, stop, and departure status information. However, when the platform shelter leaks or when there's heavy rain or strong wind, rainwater can leak into or hit the LED guide screens at an angle, causing water ingress and potentially malfunctioning. Water ingress into the LED unit boards can also cause corrosion, severely shortening their service life.

[0003] In the prior art, the following are commonly used:

[0004] 1. The cabinet made of aluminum profiles specially used for LED display screens is mainly used indoors and does not have functions such as waterproof, dustproof and wind pressure proof. Rainwater and dust entering the cabinet will directly affect the service life of the LED guide screen.

[0005] 2. The box is made by bending the cold plate and then welding. This box is commonly used in the LED guide screen of the passenger station platform. Although some manufacturers’ technical solutions have added dust-proof acrylic plates to solve the problems of dustproof and wind pressure resistance, the waterproof problem has not been completely solved.

[0006] 3. Adding electronic potting glue to the LED unit board. This method delays the corrosion of the circuit board caused by rainwater intrusion. However, the LED guide screen contains devices such as the switching power supply, screen control card, and network switch. These devices will still be corroded by rainwater, and the corrosion may even extend to the LED unit board. At the same time, the addition of electronic potting glue increases the difficulty of repairing the LED guide screen. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Passenger station platform LED guide screens are typically installed beneath the platform canopy, high up near the edge of the platform safety line to ensure good visibility for passengers. However, the canopy requires holes for the catenary support, which can result in leaks. Furthermore, the platform's location in a windy area is subject to strong winds. These factors can cause the unit panels to fall off due to strong winds or be damaged by rainwater seepage.

[0029] This solution is based on actual application and follows the idea of ​​"it is better to drain than to block, and it is better to guide than to drain". Continuous and uninterrupted diversion grooves 3 are added above and on both sides of the waterproof box. Before the rainwater comes into contact with the unit panels and other equipment in the waterproof box, the diversion grooves 3 are used to guide the rainwater out of the waterproof box and naturally fall onto the platform surface.

[0030] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. The numbers of any elements in the drawings are for illustration only and not for limitation, and any names are for distinction only and do not have any limiting meaning.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] Example 1 of the special waterproof box for the LED guide screen of the passenger station platform provided by the utility model:

[0033] like Figure 1-2As shown, a special waterproof box for the LED guide screen of the passenger station platform includes a front box 2 and a rear box 1. The rear box 1 is one of the main supporting structures of this scheme. A display panel 4 is fixedly installed on the front of the rear box 1. The display panel 4 includes several display unit panels. Continuous and uninterrupted guide grooves 3 are provided above and on both sides of the display panel 4. These guide grooves 3 are fixedly installed on the rear box 1 on the same side as the display panel 4. The guide grooves 3 are designed to drain rainwater that may flow into the inside of the waterproof box to the outside of the waterproof box, thereby avoiding short circuit or damage to electrical equipment caused by moisture accumulation.

[0034] like Figure 1 As shown, the front box 2 and the rear box 1 are hinged on the adjacent top edges by hinges 6, which facilitate opening and closing during daily maintenance, thereby improving the convenience of maintenance. The front box 2 includes a frame 21 and a windproof plate 22. The frame 21 is matched with the rear box 1 and is made of multiple steel plates that are bent and welded as a whole. The windproof plate 22 is fixedly installed on the side of the frame 21 close to the unit board. When the front box 2 is closed, it is fixedly connected to the rear box 1 by a hidden lock (not shown in the figure). This design can effectively prevent wind pressure and block strong winds from blowing directly towards the display panel 4, reducing the risk of screen shaking or damage caused by wind. At the same time, the front box 2 is located on the outside of the display panel 4, forming a complete protective cover when closed, further improving the overall waterproof and dustproof capabilities.

[0035] In this embodiment, the guide trough 3 is configured as a U-shaped trough, and a bent baffle 8 is provided inside the frame 21. When the front box 2 is closed, the baffle 8 is horizontally located directly above the guide trough 3. Although a gap is left between the baffle 8 and the guide trough 3 to facilitate the opening and closing of the front box 2, the working environment of this solution is located under a canopy, which blocks most of the rainwater, and rainwater can only enter the waterproof box through the gap between the front box 2 and the rear box 1. Therefore, the amount of rainwater that can enter the guide trough 3 is greatly reduced, and it is difficult for rainwater to overflow from the guide trough 3 into the interior of the waterproof box. In addition, the baffle 8 above the frame 21 can also effectively reduce the splashes generated when rainwater drips into the guide trough 3, preventing the splashes from splashing into the interior of the box.

[0036] Example 2 of the special waterproof box for the LED guide screen of the passenger station platform provided by the utility model:

[0037] The main difference between it and Example 1 is:

[0038] like Figure 3 As shown, a magnetic column 5 is fixedly mounted on the back of the display panel 4, and the display panel 4 is adsorbed to the front of the rear box 1 via the magnetic column. In the event of a malfunction, the display panel 4 and the magnetic column 5 can be easily removed from the rear box 1, facilitating front maintenance. A certain amount of space is left between the display panel 4 and the rear box 1, and a drainage hole 7 is provided at the bottom of the frame 21 and the bottom of the rear box 1.

[0039] If rainwater unexpectedly enters the waterproof case, the space between the display panel 4 and the rear case 1 effectively prevents water from accumulating. Under the action of gravity, the water flows to the frame 21 or the bottom of the rear case 1 and out through the drain holes 7. Furthermore, the front case 2 and the rear case 1 are not completely sealed, so trace amounts of water vapor remaining in the waterproof case can be carried out along the gap between the front and rear cases 2 and 1 by breeze or sunlight, thus preventing short circuits or damage to electrical equipment caused by moisture accumulation.

[0040] Example 3 of the special waterproof box for the LED guide screen of the passenger station platform provided by the utility model:

[0041] The main difference between it and Example 2 is:

[0042] like Figure 4 As shown, the front and back sides of the rear box body 1 are provided with unit panels and a front box body 2 for protecting the unit panels. This design allows passengers to see the information on the guide screen from both the front and rear directions, expands the coverage of the information, avoids congestion and confusion that may be caused by a single-sided display screen during peak traffic hours, and enhances user experience and safety.

[0043] While the above-described ideal embodiments of the present invention serve as a guide, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art will appreciate numerous modifications, variations, and alternatives without departing from the concept and spirit of the present invention. It should be understood that in practicing the present invention, various alternatives to the embodiments of the present invention described herein may be employed. The appended claims are intended to define the scope of the present invention and, therefore, cover modular components, equivalents, or alternatives within the scope of these claims.
