Description

Technical Field

[0001] The utility model relates to the technical field of tunnel fire emergency evacuation, in particular to a tunnel evacuation dynamic indication sign. Background Art

[0002] Tunnel evacuation signs are signs that indicate evacuation instructions and route prompts inside the tunnel. They are an important safety facility. Tunnel evacuation signs are set on the walls on both sides of the tunnel, with one set every 50 meters. The numbers on both sides of the signs represent the length of the evacuation passages on both sides. When escaping, you can follow the instructions on the evacuation signs to escape to the nearest evacuation passage or exit. Tunnel evacuation signs play an important role in guiding and directing people in situations such as fire, accidents, and vehicle failures, helping people evacuate quickly, orderly, and safely.

[0003] However, tunnel evacuation signs are only simple static signs indicating safe exits. If an accident such as a fire occurs in the nearest evacuation passage or safe exit, the escape distance indication on the tunnel evacuation signs will be incorrect and fail to guide people to evacuate to the safest exit.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-3 As shown, a tunnel evacuation dynamic indication sign includes:

[0029] A green prompt panel 1, on which an escape prompt window, a left indication window and a right indication window are arranged;

[0030] The prompt back plate 2 is provided with a first red LED light group 21 arranged in an "X"-shaped array and a second red LED light group 22 arranged in an arrow-shaped array, wherein:

[0031] The first red LED light group 21 / the second red LED light group 22 correspond to the left indication window / the right indication window respectively;

[0032] The white LED light board module 3 has its irradiation surface facing the prompt backboard 2.

[0033] Specifically, the escape prompt window, the left indication window and the indication marks on the right indication window on the green prompt panel 1 are white, and the green prompt panel 1 is tempered glass or a green light-transmitting acrylic plate.

[0034] The prompt back panel 2 is a white acrylic translucent panel. When the white LED light board module 3 is running, light will shine through the prompt back panel 2 onto the green prompt panel 1, thereby separately illuminating the escape prompt window, the left indication window and the right indication window.

[0035] In addition, the first red LED light group 21 and the second red LED light group 22 are composed of LED lamp beads 101 arranged at the center of the shade body 100 and not in contact with the inner wall of the shade body 100. The inner wall of the shade body 100 is provided with a conical reflector 102. When an emergency occurs, the white LED light board module 3 continues to illuminate, and the first red LED light group 21 and the second red LED light group 22 are respectively lit, and the wrong escape direction is prompted by the first red LED light group 21 arranged in an "X" array, and the correct wrong escape direction is prompted by the second red LED light group 22 arranged in an arrow array.

[0036] It should be noted that the first red LED light group 21, the second red LED light group 22 and the white LED light board module 3 in the above embodiment are all directly powered by an external mains power supply of 220V.

[0037] In the above technology, the structure is simple and the operation is convenient. In order to solve the problem of unclear identification in emergency situations, the first red LED light group 21 and the second red LED light group 22 are added for special reminders to facilitate timely identification of escape and avoid escaping in the wrong direction.

[0038] As a further embodiment of the present invention, the green prompt panel 1, the prompt back panel 2 and the white LED light board module 3 are sequentially placed in the groove of the panel frame 4, and then the heat dissipation fin back panel 6 is placed in, and fits with the backlight surface of the white LED light board module 3. Then the panel frame 4 is buckled on the mounting plate 7 (metal plate) fixed on the wall in advance, and then the panel frame 4 and the mounting plate 7 are combined by screws.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
