Description

Technical Field

[0001] The utility model relates to the field of tunnel safety, in particular to an automatic opening device for rolling shutter doors of a tunnel communication passage. Background Art

[0002] There is a communication channel in the middle of the separated tunnel, which is divided into a vehicle tunnel and a pedestrian tunnel, for the evacuation of personnel and vehicles in the event of a fire in the tunnel. The communication channel is separated by a rolling shutter door, which is usually closed. In an emergency, these rolling shutter doors can be opened in three ways: one is that the on-duty personnel remotely control the opening in the central control room of the tunnel; the second is that the trapped personnel manually lift the rolling shutter door at the rolling shutter door; the third is that the trapped personnel press the opening button at the rolling shutter door to open it automatically. All three methods require personnel participation, which wastes precious escape time and increases the uncertainty of human operation. Since the current tunnels are equipped with fire warning devices, if they are linked with the rolling shutter doors, more time for the trapped personnel to escape can be effectively gained and the impact of human uncertainty can be reduced.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural diagram of the automatic opening device of the rolling shutter door of the tunnel communication channel. DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0012] See also Figure 1 , is a schematic structural diagram of an automatic opening device for rolling shutter doors of a tunnel communication passage provided by the utility model.

[0013] The utility model provides an automatic opening device for rolling shutter doors of a tunnel communication passage, which is used in tunnels with electric rolling shutter doors and fire warning devices preset therein, and comprises a controller (not shown in the drawings), an installation box 1 and a wire duct 2.

[0014] The installation box 1 is a stainless steel box with a cabinet door 11 on the front and a controller inside. A circle of stainless steel installation plates 12 in a "C" shape and perpendicular to the top surface of the installation box 1 are welded along the left, front and right edges of the top of the installation box 1. A wiring hole is provided in the middle of the top of the installation box 1, which is recorded as the first wiring hole 31. Multiple installation holes are drilled along the installation plate 12, which are recorded as the first installation holes 32. On the inner side of the installation plate 12, a piece of foam pad 13 is attached to the three surfaces by gluing to play a buffering role.

[0015] Another wiring hole is provided at the middle of the right side of the installation box 1, which is marked as the second wiring hole 33. On both sides of the second wiring hole 33, two rows of mounting holes are symmetrically provided along the vertical direction, which are marked as the second mounting holes 34.

[0016] The wire trough 2 is basically the same as the existing wire trough 2, including a trough body and a trough cover. A connecting plate 21 is extended from both sides of the back of the lower end of the trough body, and two rows of mounting holes are symmetrically arranged along the length direction, which are recorded as third mounting holes 36. A wiring hole is also provided at the lower end of the trough body near the middle of the connecting plate 21, which is recorded as the third wiring hole 35. The actual length of the wire trough 2 is much longer than the length shown in the figure, and measures such as turning and connecting with the inner wall of the tunnel can be implemented according to the situation to further extend it to a position in the tunnel close to the fire warning device.

[0017] The motor of the electric rolling door is provided with a protective cover. Before installation, several mounting holes are drilled on the outer side of the protective cover near the bottom, and a wiring hole is drilled at the bottom, which are respectively recorded as the fourth mounting hole and the fourth wiring hole.

[0018] Align the fourth mounting hole with the first mounting hole 32, and align the fourth wiring hole with the first wiring hole 31. Pass the rivet through the fourth mounting hole, the first mounting hole 32 and the foam pad 13, tighten and fix, and install the installation box 1 under the protective cover.

[0019] Align the third wiring hole 35 with the second wiring hole 33, and align the third mounting hole 36 with the second mounting hole 34. Pass the rivet through the third mounting hole 36 and the second mounting hole 34, tighten and fix, and install the wire trough 2 on the side of the installation box 1.

[0020] The controller in the installation box 1 is routed through the fourth wiring hole and the first wiring hole 31, and connected to the motor of the electric rolling door; on the other hand, it is routed through the third wiring hole 35, the second wiring hole 33 and the wire trough, and connected to the sensor of the fire warning device.

[0021] The controller obtains the sensor signal of the fire warning device. When it determines that there is a fire risk based on the signal, it can skip other control systems and directly control the electric rolling door to open, thus ensuring the safety of people in the tunnel to the greatest extent possible and buying time for escape.

[0022] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
