[0019] Please refer to Figure 1 - Figure 3The utility model provides a warning device for entering tunnel, including device body 1 and caption display screen 2, one side of device body 1 is fixedly installed with receiving box 4, motor 5 is fixedly installed in receiving box 4, the output of motor 5 is fixedly connected with lead screw 6, is screwed on the lead screw 6 with sliding ring 7, sliding ring 7 is fixedly connected with connecting rod 8, and one end of connecting rod 8 penetrates the inside of receiving box 4, one end of connecting rod 8 is fixedly connected with moving plate 10, and moving plate 10 is located in the front of caption display screen 2, and the dust pad 11 is detachably connected on moving plate 10, and the dust pad 11 is in contact with caption display screen 2, and the warning device for entering tunnel is a kind of equipment for improving tunnel driving safety, and the warning device for entering tunnel is generally installed at tunnel entrance, power supply device, wireless remote control module, control system and LTD lamp group are provided in device body 1, power supply device provides electric energy for LTD lamp group, so that the pattern or caption formed by LTD lamp group is shown on caption display screen 2, to convey information for driver, to remind driver to pay attention to speed limit, turn on car light, pay attention to potential danger etc., but too many vehicles come and go in tunnel, and too many vehicles can generate a large amount of dust and fine particles, these dusts suspend in tunnel, along with air flow and the air current generated when vehicle drives, gradually deposit on the surface of warning device, and the accumulation of dust and dirt can make traffic sign or text on warning device become blurred, so as to cause the visual judgment of driver to be affected, leading to the problem of increased traffic accident risk, when caption display screen 2 is dusted, the dust pad 11 is installed to facilitate the dusting of caption display screen 2, first, motor 5 drives lead screw 6 to rotate by wireless remote control, and lead screw 6 drives connecting rod 8 to move up and down in bar slot 9 when rotating, simultaneously, connecting rod 8 drives moving plate 10 to move up and down in the front of caption display screen 2, then, dust on caption display screen 2 is cleaned by dust pad 11, to avoid too much dust on caption display screen 2 leading to indicating pattern or font becoming blurred, the dust pad 11 ensures that the text or pattern on warning device is always clear by cleaning caption display screen 2, reduces the risk of traffic accident, and the dust pad 11 is connected with moving plate 10 by magic tape or adhesive, to facilitate regular dismounting, replacing or cleaning of dust pad 11 by staff.

[0020] Please refer to Figure 3 One side of receiving box 4 is provided with bar slot 9, and one end of connecting rod 8 penetrates the inside of bar slot 9 and is slidably connected with bar slot 9, and connecting rod 8 penetrates the inside of receiving box 4 through bar slot 9, and bar slot 9 also plays a guiding and limiting role on connecting rod 8.

[0021] Please refer to Figure 1 And Figure 2The side of the storage box 4 is provided with a connecting assembly, the connecting assembly is connected with a mounting plate 12, and the mounting plate 12 is fixed on the wall body. The mounting plate 12 is fixedly connected with a mounting bin 13, and a plurality of buffer assemblies are installed in the mounting bin 13. The back of the device body 1 is fixedly connected with a connecting groove 14, and the connecting groove 14 is arranged in the mounting bin 13 and fixedly connected with the buffer assembly. When the stability of the warning device is improved, the buffer assembly is installed to improve the stability of the warning device. When the vehicle passes through the warning device quickly, the air flow around the vehicle is disturbed to form turbulence and vortex. These air flows can generate dynamic wind load on the signboard, especially in the narrow space such as the tunnel entrance. When the wind load acts on the device body 1 through the installed buffer assembly, the device body 1 moves in the mounting bin 13 through the buffer assembly, so that the impact force received by the device body 1 is reduced, and the problem that the warning device is disconnected or damaged at the connection between the device body 1 and the wall body during long-time work is avoided. The stability and service life of the warning device are improved.

[0022] Please refer to Figure 1 and Figure 2 The connecting assembly comprises a sliding groove 17 and a sliding block 18. The sliding groove 17 is symmetrically arranged on the mounting plate 12, and the sliding block 18 is slidingly installed in the sliding groove 17. The other end of the sliding block 18 is fixedly connected with the storage box 4. The device body 1 is connected with the mounting plate 12 through the sliding groove 17 and the sliding block 18, so that the stability of the device body 1 is ensured. At the same time, the device body 1 moves without being hindered when the device body 1 is vibrated and impacted through the sliding block 18 sliding in the sliding groove 17.

[0023] Please refer to Figure 2 The buffer assembly comprises a spring 15 and a damper 16. The spring 15 is fixedly installed in the mounting bin 13, and the other end of the spring 15 is fixedly connected with the connecting groove 14. The damper 16 is fixedly installed in the mounting bin 13, and one end of the damper 16 penetrates the inside of the spring 15 and is fixedly connected with the connecting groove 14. The spring 15 provides initial elastic support for the device body 1 and absorbs impact energy. The damper 16 reduces vibration and oscillation by consuming the energy. The impact force received by the device body 1 is reduced through the cooperation of the spring 15 and the damper 16, the device body 1 is prevented from excessive vibration, and the stability and durability of the warning device are improved.

[0024] Please refer to Figure 1 The device body 1 is provided with a color light belt 3, and the color light belt 3 is arranged outside the subtitle display screen 2. The color light belt 3 further increases the conspicuousness of the warning device, and avoids that the driving personnel ignores the warning device.

[0025] The working principle is that when the subtitle display screen 2 is dusted, the dust removal pad 11 is installed to facilitate dusting of the subtitle display screen 2. First, the motor 5 is started by wireless remote control to drive the screw rod 6 to rotate. When the screw rod 6 rotates, the connecting rod 8 is driven to move up and down in the bar-shaped groove 9 through the slip ring 7, and at the same time, the connecting rod 8 synchronously drives the moving plate 10 to move up and down in front of the subtitle display screen 2, thereby cleaning the dust on the subtitle display screen 2 through the dust removal pad 11. The accumulation of too much dust on the subtitle display screen 2 causes the indication pattern or font to become blurred, and the dust removal pad 11 ensures that the text or pattern on the warning device is always clear and visible, reducing the risk of traffic accidents. When improving the stability of the warning device, the buffer assembly is installed to improve the stability of the warning device. When the vehicle passes through the warning device quickly, it will disturb the surrounding air flow and form turbulence and vortex. These air flows can generate dynamic wind load on the signboard, especially in such narrow spaces as tunnel entrances. When the wind load acts on the device body 1 through the installed buffer assembly, the device body 1 will move in the installation bin 13 through the buffer assembly, reducing the impact force on the device body 1, avoiding the problem of cracking or damage of the warning device at the connection with the wall during long-term work, and improving the stability and service life of the warning device.
