Description

Technical Field

[0001] The utility model relates to the technical field of tunnel escape, in particular to a tunnel fire safety escape indicating device. Background Art

[0002] The characteristics of highway tunnel fires include fast burning and spreading speed, slow smoke diffusion, high toxicity, difficulty in rescue and evacuation, and difficulty in rapid disposal. In particular, fires in long tunnels have the above characteristics more strongly, which will cause more serious harm and loss to people's lives and property. In order to reduce losses, it is necessary to indicate a correct and shortest escape route to the people in the tunnel, so as to shorten the escape time to a minimum and avoid or reduce the damage to people caused by burning and poisonous substances. Highway tunnels are generally two connected tunnels. When a fire occurs in one of the tunnels, the evacuees in the fire tunnel can be transferred to the safe tunnel on the other side through the pedestrian crossing. However, the existing pedestrian crossings mainly use display screens or indicator lights to guide the entrance of the pedestrian crossing. The prompt methods of these pedestrian crossings have the following problems:

[0003] 1. The existing display screen can only provide guidance for evacuees in a single direction at the entrance of the pedestrian crossing. If it is necessary to provide guidance for evacuees in two directions at the entrance of the pedestrian crossing, at least two display screens are required, which results in high guidance costs.

[0004] 2. Guidance is provided by displaying fonts. As the distance increases, the reminder effect of the display screen will become less effective;

[0005] Therefore, it is necessary to provide a tunnel fire safety escape indication device which can provide guidance in multiple directions, reduce guidance costs, and have a better reminder effect. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the utility model provides a tunnel fire safety escape indicating device.

[0007] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the utility model is: it includes a rotatable indicator screen installed at the end of the pedestrian crossing and a light strip installed inside the pedestrian crossing; the rotatable indicator screen includes a roller and a flexible display screen, the flexible display screen is fixed on the outer circumferential surface of the roller, and hollow rotating shafts are fixed at the bottom and top of the roller, and the hollow rotating shafts are fixedly connected to the roller through end plates, and the hollow rotating shaft at the top is connected to a driving mechanism, and the bottom and top of the roller are respectively installed on the pedestrian crossing through an upper bracket and a lower bracket.

[0008] Furthermore, the driving mechanism includes a driven gear, a driving gear and a driving motor. The driven gear is fixed to the outside of the hollow shaft, the driven gear is meshed and connected with the driving gear, and the driving gear is fixed to the output end of the driving motor.

[0009] Furthermore, an upper rotating shaft end for installing the hollow rotating shaft is fixed on the upper bracket, and a lower rotating shaft end for installing the hollow rotating shaft is fixed on the lower bracket, and rotating shaft installation holes are provided on both the upper rotating shaft end and the lower rotating shaft end.

[0010] Furthermore, the flexible display screen is fixed on the roller by bonding or clamping.

[0011] Furthermore, an audible and visual alarm is arranged on the hollow rotating shaft at the bottom.

[0012] Furthermore, the connection harness of the flexible display screen is connected via a power rotary joint.

[0013] Furthermore, the light strips are arranged at four locations, two of which are arranged at the bottom of both sides of the pedestrian crossing, and two of which are arranged in the middle of both sides of the pedestrian crossing.

[0014] Furthermore, a slot for installing the light strip is provided on the inner wall of the pedestrian crossing passage, fixed edges are provided on both sides of the light strip, the slot is U-shaped, and clamping edges for installing the light strip are provided on the inner sides of the two tops of the slot.

[0015] Furthermore, the card slot and the card edge are integrally formed.

[0016] The beneficial effects of the utility model are:

[0017] The rotatable indicator screen of the utility model is inspired by the hairdressing rotating lights outside the barber shop. The hairdressing rotating lights have a good eye-catching effect, and the hairdressing rotating lights can be seen by people in the nearby area, and have a good prompting and guiding effect. The rotatable indicator screen of the utility model also adopts this principle. The rotatable indicator screen rotates to display a specific pattern, so that the evacuees can recognize the nearby pedestrian crossing at a glance. The rotatable indicator screen can display single tones such as red, green or blue, and can also display a combination of colors similar to the hairdressing rotating lights. It can also display fonts of specific colors to serve as a reminder for the evacuees.

[0018] The rotatable indicator screen of the utility model can play a similar eye-catching role as a hairdressing rotating light, can guide the evacuees, and make it convenient for the evacuees to know the location of the pedestrian crossing, thereby facilitating the evacuees to evacuate to a safe area. Compared with the traditional flat display screen, the rotatable indicator screen has a wider display range, and can play a good indicating role for the evacuees on both sides of the end of the pedestrian crossing, so that the evacuees can find the location of the nearby pedestrian crossing at the first time, so as to facilitate the orderly evacuation of the evacuees.

Then, the flexible display screen 37 is fixed to the outer surface of the roller 35, and the flexible display screen 37 can be fixed by bonding or clamping, and the driving mechanism is installed on the top hollow shaft 36, and the driven gear 38, the driving gear 39 and the driving motor 30 of the driving mechanism are installed, and the sound and light alarm 4 is installed on the bottom hollow shaft 36. After the rotatable indicator screen 3 is installed, four light strips are installed in the pedestrian cross passage 2. Two light strips 5 are installed at the bottom of both sides of the pedestrian cross passage 2, and two light strips 5 are set in the middle of both sides of the pedestrian cross passage 2. The light strips 5 are slidably installed in the card slot 6, which can facilitate the installation of the light strips 5 to the greatest extent. The rotatable indicator screen 3 is installed at both ends of the pedestrian cross passage 2. When a fire occurs in a tunnel, the rotatable indicator screen 3 located on the side close to the fire is used to display the escape route, etc., which is convenient for reminding and indicating the evacuees.
