Description

Technical Field

[0001] This utility model relates to the field of traffic information display equipment technology, specifically to an LED road traffic information display screen. Background Technology

[0002] LED information displays are an important component of modern Intelligent Transportation Systems (ITS). Their core functions are to proactively guide traffic, provide real-time information, ensure driving safety, and improve road efficiency. They are electronic display devices installed above or beside roads, composed of thousands of light-emitting diodes (LEDs). Even in strong sunlight, the displayed content remains clearly visible. Furthermore, road traffic information displays are reliable, capable of operating 24 hours a day in harsh outdoor environments (such as sunlight, rain, high and low temperatures, and vibration). All display content on road traffic information displays is remotely published and updated in real time by the traffic management center via wired or wireless networks (such as fiber optics, 4G / 5G).

[0003] For example, application number 202321461283.0, entitled "An Interactive Scenic Area Traffic Direction Device," discloses an interactive scenic area traffic direction device, relating to the field of traffic direction technology. It includes a support rod with a protective component fixed to its top. The protective component includes a protective box welded to the top of the support rod, and a movable plate is rotatably connected to the rear surface of the protective box via a hinge. This utility model protects the display screen through a protective shell and a rain shield, preventing rainwater from damaging internal electronic components. Simultaneously, rainwater can be collected and channeled into a heat dissipation frame, providing cooling for the display screen in hot weather. A terminal-controlled motor drives a reciprocating screw to rotate, causing a cleaning strip to wipe dust from the display screen. Combined with a water-filling component, this improves the cleaning effect. Furthermore, a loudspeaker allows users to access scenic area road traffic information, preventing further congestion. The interactive device allows communication with terminal management personnel, facilitating the alleviation of road congestion.

[0004] The shortcomings of existing technology are that traffic information displays are installed on pillars along the road and are directly exposed to the external environment. Changes in the external environment can easily interfere with their service life. When the external temperature is high, it can easily affect the performance of their internal components, resulting in problems such as LED light source decay, display screen deformation, and reduced sealing performance. Therefore, there are certain deficiencies. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0029] Please see Figure 1-4This embodiment provides an LED road traffic information display screen, including a screen body 1 and a support column 2. The screen body 1 is mounted on the support column 2, and is installed on the side of the top of the support column 2, keeping the screen body 1 above the road for real-time display of road traffic information. A movable block 3 is slidably connected to the back of the screen body 1, and the movable block 3 is provided with an atomizing nozzle 4 and auxiliary components. A mounting frame 5 is fixedly connected to the back of the screen body 1, and a driving component is provided in the mounting frame 5 to drive the movable block 3 to move back and forth, so that the atomizing nozzle 4 moves to spray water mist to cool the top of the screen body 1. The atomizing nozzle 4 is driven by the driving component. Under the action of the device, it can perform scanning spraying along the back of the screen 1. The sprayed fine water mist evenly covers and adheres to the surface of the screen 1. The water absorbs a large amount of heat during evaporation, thereby achieving efficient and uniform physical cooling of the display screen. This effectively avoids a series of problems caused by prolonged high-temperature working environment, such as premature decay of LED light source, display color distortion, thermal deformation of screen 1 material, and aging and failure of internal sealant. It greatly improves the operational stability and durability of the display screen in summer or high-temperature areas. The support column 2 is equipped with a water storage frame 6 for collecting rainwater. The top of the water storage frame 6 is set in an inclined shape. This structure greatly improves its efficiency in collecting natural rainwater. A filter screen 11 is installed at the sloping top of the water storage frame 6, providing some protection and interception. The water storage frame 6 is connected to the atomizing nozzle 4 via a flexible hose 7. A water pump can be installed inside the water storage frame 6 to transport the water stored in the water storage frame 6 to the atomizing nozzle 4 for recycling. The water storage frame 6 can also be connected to an external water supply system. Its specific usage can be selectively configured according to specific needs. The moving block 3 is also equipped with a trigger component that drives the auxiliary component to rotate. As the moving block 3 moves, and with the cooperation of the triggering component, the auxiliary component can rotate while moving. The rotation of the auxiliary component can generate airflow and visual disturbance, which can effectively drive away birds that try to stay or nest on the screen 1, preventing them from blocking the display content or polluting the surface of the screen 1 with their excrement. At the same time, the rotation of the auxiliary component can also agitate the water mist sprayed from the atomizing nozzle 4, accelerate the mixing of water mist and air and expand its diffusion range, so that the water mist can cover a larger area of ​​the screen 1 more evenly. This not only improves the uniformity and efficiency of cooling, but the rotating auxiliary component also has a certain cleaning and blowing function.

[0030] In a further embodiment of this utility model, the driving component includes a reciprocating screw 8 rotatably connected in the mounting frame 5. A drive motor 9 is also mounted on the back of the screen 1, and the output end of the drive motor 9 is connected to the reciprocating screw 8 via a belt 10. The drive motor 9 is connected to an external power supply and a control switch, and is used to provide stable kinetic energy for the rotation of the reciprocating screw 8. A moving block 3 is threadedly connected to the reciprocating screw 8. The moving block 3 has a threaded hole inside that is adapted to the reciprocating screw 8. The moving block 3 forms a threaded transmission pair with the reciprocating screw 8 through the threaded hole inside. The moving block 3 slides laterally on the mounting frame 5. A protective frame 16 is also provided on the back of the screen 1 to protect the drive motor 9 and the belt 10. The protective frame 16 is provided to protect the drive motor 9 and the belt 10 transmission mechanism from the harsh outdoor environment such as sun exposure, rain, and dust corrosion, thereby extending the service life and reliability of the core driving components.

[0031] In a further embodiment of this utility model, the auxiliary component includes a rotating rod 12 rotatably connected to the moving block 3, and a blade 13 is provided on the rotating rod 12. The triggering component includes a rack 14 fixedly connected to the mounting frame 5, and a gear 15 is provided on the rotating rod 12. The gear 15 meshes with the rack 14. When the moving block 3 moves, the gear 15 on the rotating rod 12 meshes with the rack 14, so that the rotating rod 12 rotates while moving. Since the rack 14 is fixed, the gear 15 is forced to rotate while moving, thereby driving the rotating rod 12 and the blade 13 connected to it to rotate together. The movement and rotation of the blade 13 can drive away birds standing on the screen 1, and while the atomizing nozzle 4 sprays water mist, it drives the water mist to spread over a wider area.

[0032] Working principle: During operation, the water pump on the hose 7 is activated to deliver water from the water storage frame 6 to the atomizing nozzle 4. At the same time, the drive motor 9 is activated to drive the reciprocating screw 8 to rotate, causing the moving block 3 on the reciprocating screw 8 to move back and forth in the mounting frame 5. The movement of the moving block 3 drives the working atomizing nozzle 4 to move, spraying water to cool the screen 1. At the same time, the movement of the moving block 3 will drive the rotating rod 12 to move synchronously. When the rotating rod 12 moves, the gear 15 on it meshes with the teeth on the mounting frame 5, so that the rotating rod 12 rotates while rotating. With the help of the blades 13, it can drive away birds standing on the screen 1, and the airflow from the rotating blades 13 can drive the atomizing nozzle 4 to spray water mist to a wider area.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
