Description

Automatically controlled tunnel entry blocking device {AUTOMATIC CONTROL TYPE TUNNEL ENTRANCE BLOCKING APPARATUS}

The present invention relates to an automatically controlled tunnel entry blocking device, and more particularly, to an automatically controlled tunnel entry blocking device having a structure that automatically controls the ascending and descending movements of a blocking film that controls the entry of a vehicle into a tunnel.

In general, due to the nature of a closed space, if a tunnel is not promptly responded to a disaster such as a traffic accident, fire, or flooding accident, a secondary accident may occur and lead to a major disaster.

In consideration of this, tunnel entry blocking devices are installed and operated around the tunnel to block vehicles from entering the tunnel by displaying the accident situation on the outside in real time when a disaster occurs in the tunnel. Typically, the tunnel entry blocking device is a barrier that can be wound or unwound on the posts and horizontal supports installed around the access road of the tunnel, the winding rods installed on the horizontal supports, and has a warning sign indicating that the entry of the tunnel is prohibited, and installed on the horizontal supports to enter the tunnel. Includes a light indicating prohibition. In addition, various sensors are installed in the tunnel entry blocking device to detect the situation around the tunnel, and transmit the detected data to the control room installed inside the tunnel or remote management room in real time to promptly notify the administrator of an accident and take action. Is composed.

The tunnel entry blocking device is installed in front of the tunnel entrance. Due to the nature of the entrance and exit of the tunnel, when it is snowed in winter, freezing occurs immediately and there is a lot of strong winds, so accidents occur frequently. It should be designed to prevent secondary accidents by fundamentally blocking traffic.

An electric tunnel entry blocking device consisting of is disclosed.

However, the conventional electric tunnel entry blocking device is configured to control the rotation of the winding rod by sensing the rotation position of the winding rod with a rotation amount detection sensor such as an encoder, etc. There is a disadvantage in that it takes a lot of time to set the device because it is difficult to control exactly stopping the rotation of the winding rod at the point and the point where it is released at the maximum.

In addition, the electric tunnel entry blocking device is equipped with a styrofoam rod and a balance weight pocket in which an antifreeze bag can be placed, but due to the difficulty in winding the antifreeze bag on the winding roll, a balance weight pocket is installed only at the bottom of the blocking film and around it. There is a possible limit, so if the wind blows strongly, the barrier still warps or fluctuates, and the barrier is difficult to maintain tight, so there is a vulnerability that the visibility of the tunnel entry barrier warning text is poor.

In addition, in order to prevent vehicle damage during a vehicle collision, a styrofoam rod is installed at the end of the blocking film, but the styrofoam rod is light in weight, so there is a problem that it is not suitable to function as a weight at the end of the blocking film.

In addition, the LED string 92 is additionally arranged along the outline of the warning character indicating that the vehicle is prohibited from entering the entrance barrier 30 to increase visibility of the warning character at night.

Automatically controlled tunnel entry blocking device according to another embodiment of the present invention having the above configuration is installed at the entrance of the tunnel to operate the warning means 40 when a disaster such as a fire, traffic accident, flooding accident occurs inside the tunnel. In addition, information on the accident situation is displayed on the electronic board 90 to notify the accident situation in real time, and at the same time, the entrance barrier 30 is automatically lowered to block the vehicle from entering the tunnel. In addition, a lane use regulation traffic light (LCS) 91 installed on the horizontal member 12 of the frame 10 indicates that vehicles are prohibited from entering each lane in the event of a disaster. The accident situation inside the tunnel is detected by the tunnel CCTV and transmitted to a remote control system including the central control device 61 and/or the mobile phone 62 in the central control room.

While the entrance barrier 30 is descending, the laser sensor 100 detects whether the vehicle 1 approaches the vicinity of the entrance barrier 30, and when approaching the vehicle, it transmits a detection signal to the control unit 50 to prevent the entry barrier. By automatically stopping the descent of 30, the vehicle 1 is prevented from colliding with the lower end of the entrance barrier 30.

In addition, the water level sensor 101 installed on one side of the tunnel detects the flooded level of the tunnel and transmits a detection signal to the control unit 50 so that when the water level is higher than a predetermined value, the entrance barrier 30 automatically descends. , The fog sensor 102 is installed inside or outside the tunnel or on a bridge to detect the surrounding fog, and then transmits a detection signal to the control unit 50 to automatically descend the entrance barrier 30 when the fog concentration is higher than a predetermined value. Let this happen.

In the above, although the present invention has been described by limited embodiments and drawings, the present invention is not limited thereto, and within the scope of the technical idea of the present invention by those of ordinary skill in the art to which the present invention pertains. Of course, various modifications and variations are possible.
