Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel traffic safety technology, and in particular to a temporary tunnel control and warning device. Background Technology
[0002] In the operation and management of highway tunnels, temporary traffic control measures such as tunnel closures due to traffic accidents, construction and maintenance, and emergency drills are common occurrences. Currently, tunnel closures mainly rely on traditional static warning facilities, such as placing cones, water-filled barriers, and retractable guardrails at tunnel entrances. Manually deploying these barriers is time-consuming, taking at least 5 to 10 minutes, which cannot meet the requirements for rapid response to emergencies. Furthermore, the cones, water-filled barriers, and retractable guardrails are placed at a low height, making them not directly in the driver's line of sight, which may cause drivers and passengers of some oversized vehicles to overlook them. Summary of the Invention
[0003] The purpose of this utility model is to provide a temporary control and warning device for tunnels.
[0004] To achieve the above objectives, the present invention can adopt the following technical solution:
[0005] The temporary tunnel control and warning device of this utility model includes a winch with a winding drum at its working end, and a manual control switch and a remote control switch for controlling the operation of the winch; the winding drum is suspended at the top center of the tunnel entrance, and a fireproof curtain with warning signs is installed on it; the manual control switch is located on one side of the tunnel entrance, and its control output terminal is electrically connected to the control input terminal of the winch; a remote control unit is installed on the winch, the signal output terminal of the remote control switch is communicatively connected to the signal input terminal of the remote control unit, and the control output terminal of the remote control unit is electrically connected to the control input terminal of the winch.
[0006] Furthermore, an LED light is installed on the tunnel entrance located in front of the winding drum, which opens and closes synchronously with the winch. The illuminating end of the LED light faces the fireproof curtain, which can illuminate the warning signs on the fireproof curtain, making it easier for vehicle occupants to see them in time and thus stop driving into the tunnel, thereby improving road safety.
[0007] Furthermore, the fireproof curtain has a T-shaped structure with a downward convex center. The upper part of the fireproof curtain is 4.5m wide and the lower part is 2.8m wide. The T-shaped fireproof curtain can avoid directly crossing the lane and obstructing the vehicle's view.
[0008] Furthermore, a counterweight crossbar is provided on the lower edge of the fireproof curtain. The counterweight crossbar not only does not affect the fireproof curtain from being rolled up in the roll-up drum, but also improves its drooping stability when unfolded downwards, reducing the phenomenon of it being blown and swayed by the wind in windy weather.
[0009] The advantages of this invention are that it can respond promptly and remotely control the winch to lower the fireproof curtain with warning signs, thereby quickly realizing the temporary closure and control of the tunnel, timely warning vehicle occupants and preventing vehicles from entering the tunnel; in addition, the fireproof curtain with warning signs is also suspended at the tunnel entrance, so that it is as directly in the driver's line of sight as possible, making it easy for occupants to see clearly, significantly improving the response speed, safety, visibility and stability of the temporary closure and control of the tunnel. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model.
[0011] Figure 2 This is a circuit block diagram of this utility model. Detailed Implementation
[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0014] like Figure 1 , 2 As shown, the temporary tunnel control and warning device of this utility model includes a winch 1 installed at the top of the tunnel entrance 100, and a manual control switch 2 and a remote control switch 3 (i.e., a remote controller) that can control the operation of the winch 1.
[0015] Specifically, the working end of the winch 1 is coaxially connected to a take-up and unwinding drum 4. The take-up and unwinding drum 4 is suspended at the top center of the tunnel entrance 100 by multiple sets of M12 chemical anchors, and its length direction should be consistent with the width direction of the tunnel entrance 100. A fireproof curtain 6 with a warning label 5 is installed on the take-up and unwinding drum 4. The fireproof curtain 6 is made of fiberglass woven fabric with a 1mm thick silicon-titanium coating on the surface. Its oxygen index is ≥32 and its fire resistance time is ≥1 hour (800℃), which meets the tunnel fire protection requirements and can effectively prevent it from being ignited. Then, a warning label 5 is coated or affixed to the side of the fireproof curtain 6 facing the outside of the tunnel entrance 100. The warning label 5 is reflective and can be clearly seen at night. In addition, the fireproof curtain 6 has a T-shaped structure with a downward convex part in the middle. Its upper width is 4.5m and its lower width is 2.8m. The T-shaped design of the fireproof curtain 6 ensures that when it is unfolded downwards, the downward convex part is located exactly at the center line of the lane, avoiding it from directly crossing the lane and obstructing the vehicle's view. Of course, a counterweight crossbar 7 can also be installed on the lower edge of the fireproof curtain 6. The counterweight crossbar 7 is fixed to the bottom edge of the downward convex part of the fireproof curtain 6. When the roll-up drum 4 rolls the fireproof curtain 6 inwards, it can ensure that the counterweight crossbar 7 is just outside the roll-up opening of the roll-up drum 4. This not only does not affect the fireproof curtain 6 from being rolled up inside the roll-up drum 4, but also improves the downward stability of the fireproof curtain 6 when it is unfolded downwards, reducing the phenomenon of it being blown and swayed by the wind in strong winds.
[0016] The manual control switch 2 is a built-in switch of the winch 1, which is located on one side wall of the tunnel entrance 100. The control output terminal of the manual control switch 2 is electrically connected to the control input terminal of the winch 1, so that the winch 1 can be directly controlled to open, close, rotate forward and reverse. Of course, a remote control unit 8 is also installed on the winch 1. The remote control unit 8 consists of a microcontroller and a wireless communication module. The signal output terminal of the wireless communication module is connected to the signal input terminal of the microcontroller. At this time, the signal output terminal of the remote control switch 3 is connected to the signal input terminal of the wireless communication module in the remote control unit 8. The control output terminal of the microcontroller in the remote control unit 8 is electrically connected to the control input terminal of the winch 1. Thus, the winch 1 can be easily controlled to lower or retract the fireproof curtain 6 through the remote control switch 3, thereby quickly realizing the temporary closure and control response of the tunnel, timely warning vehicle occupants, and preventing vehicles from entering the tunnel. In addition, the fireproof curtain 6 with warning signs 5 is also suspended in the center of the tunnel entrance 100, facing the driver's line of sight as much as possible, making it easy for occupants to see, significantly improving the response speed, safety, visibility, and stability of the temporary closure and control of the tunnel.
[0017] Furthermore, LED lights 9 can be installed on the tunnel entrance 100 located in front of the winding drum 4. The LED lights 9 are in pairs, symmetrically fixed on the left and right sides of the tunnel entrance 100. The control input terminals of the two LED lights 9 are electrically connected to the control output terminals of the microcontroller in the remote control unit 8, so that they can be opened and closed synchronously with the winch 1. The illumination ends of the two LED lights 9 are both facing the fireproof curtain, so that the LED lights 9 can be turned on or off at the same time as the winch 1 is opened or closed, thereby illuminating the warning sign 5 on the fireproof curtain 6, so that vehicle occupants can see it in time and stop entering the tunnel, thus improving road safety.
