Description

Technical Field

[0001] The utility model relates to the technical field of electro-optical sign boards, in particular to an electro-optical sign board for visual safety guidance of a tunnel. Background Art

[0002] Electro-optical signs are devices that use electronic display technology to display text, graphics or animations. They are usually made up of components such as LED light-emitting diodes or LCD liquid crystal displays. These signs can be used in various occasions, such as commercial advertisements, public information releases, traffic instructions, etc. The advantages of electro-optical signs include high brightness, long-distance visibility, easy content update, and energy saving and environmental protection, so they are widely used in modern society.

[0003] After long-term use, electro-optical signs in tunnels are exposed to dust, rain, vehicle exhaust and other environments, and dust often accumulates on the surface, resulting in a decrease in display effect. However, cleaning these signs is not easy. First, the complex terrain, narrow roads and dense traffic in tunnels create certain safety hazards for cleaning staff; secondly, due to the long length of the tunnel, the staff need to spend a lot of time and energy to clean all the signs, which increases the difficulty and cost of the work. In addition, since electro-optical signs are usually installed at a high position, professional equipment and tools are required to clean them, which further increases the difficulty of cleaning. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model proposes a tunnel visual safety guidance electro-optical sign which can protect the sign body from dust, clean itself and reduce manual intervention.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: a tunnel visual safety guidance electro-optical sign, comprising a main board body and a sign board body, a square box is connected to the middle of the front of the main board body, a glass is arranged in front of the square box, an outwardly extending lip plate is arranged under the square box and directly below the glass, there is no baffle on the lower side of the square box, the sign board body slides into and is fixed in the square box, an oblique extension rod is connected to the upper end of the front of the main board body, a liftable cleaning structure is connected to the extended end of the oblique extension rod, and the water spray hole on the cleaning structure is obliquely facing the glass.

[0006] Furthermore, a plurality of equally spaced warning lights are connected to both sides of the front of the main board, and the warning lights flash in turn.

[0007] Furthermore, slide grooves are provided on both sides of the front of the main board body, a slider that can extend into and slide in the slide groove is connected to the back of the signboard body, an upper plate is connected to the top of the signboard body, magnet one is connected on both sides of the upper plate, and magnet two that attracts magnet one is connected to the upper side of the square box.

[0008] Furthermore, a first power docking device is connected to the upper plate, and a second power docking device is connected to the upper inner side of the square box.

[0009] Furthermore, the cleaning structure includes a fixed plate connected to the extended end of the oblique extension rod, and synchronous reels are connected on both sides of the fixed plate. A suspension rope passing through the fixed plate is wound around the reel, and a long water sprayer is connected under the suspension rope, and a plurality of water spray holes are equidistantly provided on the long water sprayer.

[0010] Furthermore, both sides of the square box are connected with sliding square cavities, a plug plate is slidably arranged in the sliding square cavity, and the signboard body is provided with a slot for inserting the plug plate.

[0011] Furthermore, a guide rod is connected to the middle of the upper portion of the elongated sprinkler, and a sliding hole which is slidably matched with the guide rod is provided on the fixing plate.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] Dust protection: The main body of the sign adopts a square box and glass structure, which can effectively prevent the intrusion of dust and other debris. The square box design can completely wrap the main body of the sign inside, while the transparent performance of the glass ensures the effectiveness of visual guidance and plays a role in dust prevention. This dust protection design can ensure the clarity and visibility of the sign, and reduce the cleaning frequency and maintenance costs caused by dust coverage.

[0014] Self-cleaning: The cleaning structure of the sign body uses a lifting cleaning device, including water spray holes, retractors, and long water sprayers. Through these devices, the sign can perform cleaning operations autonomously without human intervention. When cleaning is required, the water spray holes will release water, the long water sprayers will spray detergent, and the retractors will assist the movement of the cleaning structure, so that the surface of the sign can be cleaned. This self-cleaning design effectively reduces the need for manual cleaning and improves the efficiency and reliability of the sign.

[0015] Reduced human intervention: The design of the sign takes into account the factors of minimizing human intervention. In addition to the self-cleaning function, it also adopts a sliding square cavity and plug-in design, so that the main body of the sign can slide and fix in the square box without human intervention. In addition, the automatic flashing function of the warning light also reduces the need for manual operation. BRIEF DESCRIPTION OF THE DRAWINGS
