Description

Technical Field

[0001] This utility model relates to the field of subway safety protection technology, specifically to a subway section air defense door derailment alarm device. Background Technology

[0002] In subway construction, underground space is divided into independent civil defense zones. At the boundary of each civil defense zone within the subway track area, airtight civil defense doors are installed, while at specific locations where trains enter and exit the station, subway section civil defense doors are installed.

[0003] To effectively address the issue of subway trains colliding with air-raid shelter doors in subway tunnels, the industry has developed a derailment monitoring and alarm device for these doors. Current technology typically provides a proximity switch signal output only for a single location on the door. However, due to the consistently damp underground environment of subways, individual points are highly susceptible to malfunction, leading to monitoring failure and causing accidents involving subway trains colliding with air-raid shelter doors.

[0004] In existing technologies, only a single proximity switch is typically installed on the door, resulting in the limited and unstable nature of the monitoring technology, which makes it difficult to meet the actual safety requirements of subway air-raid shelter doors. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a derailment alarm device for subway air-raid shelter doors. This solves the problem that existing technologies typically only use a single proximity switch for the door, resulting in the limited and unstable monitoring technology and making it difficult to meet the actual safety protection needs of subway air-raid shelter doors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a subway tunnel air-raid shelter door derailment alarm device, comprising an alarm unit installed inside the tunnel, wherein air-raid shelter doors are installed inside the tunnel, and the alarm unit is used to detect the air-raid shelter doors. The alarm unit includes:

[0014] Preferably, the air defense door is provided with a pivot, which is inserted into the inner side of the fixing kit and the rotating kit. Fixing blocks are connected to both ends of the pivot, and the fixing blocks are connected to the outer side of the door frame.

[0015] Preferably, a connecting plate is connected to the outside of the alarm control box, and a first fixing bolt connected to the tunnel wall is inserted into the inside of the connecting plate. A sleeve is sleeved on the outside of the ground attitude monitor, and a support rod is connected to the outside of the sleeve. The support rod is inserted into the ground inside the tunnel.

Combined with three evenly distributed proximity switches 34 that collect signals from different dimensions, a multi-layered protection mechanism is established. When one monitoring point malfunctions, the others continue to function normally, providing effective monitoring data. This significantly reduces the risk of accidents caused by single-point failures, fundamentally preventing subway train collisions with the air-raid shelter door 2.

[0038] Furthermore, tunnel 1 is provided with tunnel wall 11, and a doorway 12 and a track 13 are provided on the inner side of tunnel wall 11, with track 13 located inside doorway 12.

[0043] Example 2

[0044] According to the appendix Figure 1-8 As shown, it includes an alarm unit 3, which is installed inside tunnel 1. A fire-fighting door 2 is installed inside tunnel 1. The alarm unit 3 is used to detect the fire-fighting door 2. The alarm unit 3 includes:

[0045] Alarm control box 31;

[0046] Ground attitude monitor 32, and a circuit connection is provided between ground attitude monitor 32 and alarm control box 31;

[0047] The wall attitude monitor 33 has two sets and is connected to the alarm control box 31 by a circuit.

[0048] A proximity switch 34 is provided, and a circuit connection is provided between the proximity switch 34 and the alarm control box 31.

[0049] It should be emphasized that the wall attitude monitor 33 is fitted with a positioning kit 331 on the outside, and a second fixing bolt 332 connected to the tunnel wall 11 is inserted into the positioning kit 331. The proximity switch 34 is provided with three evenly distributed sets, and a fixing anchor rod 341 fixedly connected to the tunnel wall 11 is fitted with the outside of the proximity switch 34.

[0050] Working principle:

[0051] When the door panel 22 deviates from its course or other abnormal situation, the ground attitude monitor 32 will sense the change in the attitude of the door panel 22 and transmit the signal to the alarm control box 31 through the circuit.

[0052] Two sets of wall attitude monitors 33 monitor the attitude changes between the tunnel wall 11 and the air-raid shelter door 2, and also transmit the signals to the alarm control box 31.

[0053] Three sets of proximity switches 34 monitor the position changes of the door panel 22 from different positions. When the position of the door panel 22 moves abnormally, the proximity switches 34 sense the change and transmit the signal to the alarm control box 31.

[0054] After receiving an abnormal signal from any one or more monitors, the alarm control box 31 immediately triggers an alarm to remind relevant personnel that the civil defense door 2 has derailed, so that timely measures can be taken to prevent the subway train from hitting the civil defense door 2.
