[0041] The fire rescue indicating lamp of the present application will be described in detail below through the following embodiments.

[0042] In this embodiment, as shown in Figure 1 and Figure 2 The fire rescue indicating lamp comprises a shell 1, which is hollow and has two open ends;

[0043] At least two groups of electric breakdown mechanisms 2 are arranged staggeredly along the direction from one end of the shell 1 to the other end, for generating electric signals when air is broken down;

[0044] The first signal lamp 3 and the second signal lamp 301 are both fixed on the lower side of the shell 1 and arranged staggeredly along the direction from one end of the shell 1 to the other end;

[0045] A controller (not shown in the figure) is electrically connected with the first signal lamp 3, the second signal lamp 301 and each group of electric breakdown mechanisms 2 respectively, for sequentially controlling the opening and closing of the first signal lamp 3 and the second signal lamp 301 according to the electric signals generated by each group of electric breakdown mechanisms 2.

[0046] In the technical solution, the shell 1 is fixed on the top surface of a room, and is usually arranged in the middle of two fire fighting passages of a building. In order to improve the accuracy of detecting electric signals, the shell 1 can be arranged with a relatively long length, or a signal amplifier can be arranged on the electric breakdown mechanism 2. Taking the arrangement along the left-right direction of the shell 1 as an example, the shell 1 can be arranged along the left-right direction and be relatively sealed around. When a fire occurs in a room, smoke gathers at the top of a corridor and diffuses in the direction capable of being ventilated. The smoke diffuses and moves from one end of the shell 1 to the other end. The electric breakdown mechanisms 2 are arranged in two groups. One group of electric breakdown mechanisms 2 is arranged near the left side of the shell 1, and the other group of electric breakdown mechanisms 2 is arranged near the right side of the shell 1. Similarly, the first signal lamp 3 is arranged near the left side of the shell 1, and the second signal lamp 301 is arranged near the right side of the shell 1. The first signal lamp 3 and the second signal lamp 301 are both white light lamps or red-green double-color lamps.

[0047] A controller (not shown in the figure) is electrically connected with each group of electric breakdown mechanisms 2, the first signal lamp 3 and the second signal lamp 301 respectively. When a fire occurs, the electric breakdown mechanisms 2 are turned on, and the power source connected with the electric breakdown mechanisms 2 simultaneously supplies power to each group of electric breakdown mechanisms 2. When the left electric breakdown mechanism 2 breaks down air to generate an electric signal earlier than the right electric breakdown mechanism 2, the controller controls the left first signal lamp 3 to be turned on, or controls the left first signal lamp 3 to be bright green, and simultaneously controls the right second signal lamp 301 to be bright red. Conversely, when the right electric breakdown mechanism 2 breaks down air to generate an electric signal earlier than the left electric breakdown mechanism 2, the controller controls the right second signal lamp 301 to be turned on, or controls the right second signal lamp 301 to be bright green, and simultaneously controls the left first signal lamp 3 to be bright red, so as to facilitate the personnel in a fire scene to distinguish the direction capable of escaping.

[0048] In some technical solutions, the electric breakdown mechanisms 2 are arranged in three groups. When detecting, the direction of a fire source can be inferred according to the sequence of electric signals generated by any two electric breakdown mechanisms 2, or the direction of the fire source can be inferred according to the sequence of electric signals generated by the three electric breakdown mechanisms 2.

[0049] In the embodiment, the electric breakdown mechanism 2 comprises:

[0050] The fixed seat 201 is arranged in the shell 1;

[0051] The guide 202 is fixed in the shell 1;

[0052] The sliding piece 203 is slidably arranged on the guide 202;

[0053] The first terminal post 204 is fixed on the fixed seat 201;

[0054] The second terminal post 205 is fixed on the sliding piece 203 and is arranged correspondingly to the first terminal post 204, and the first terminal post 204 and the second terminal post 205 are used for external connection of power supply;

[0055] The driving mechanism 206 is arranged in the shell 1 and is connected with the sliding piece 203, and is used for driving the sliding piece 203 to move close to or away from the fixed seat 201;

[0056] The controller is connected with the first terminal post 204 and the second terminal post 205 respectively.

[0057] In the technical solution, the first fixed seat 201 is arranged in a C shape on the inner top surface of the shell 1, so that the first terminal post 204 fixed thereon is at a certain distance from the shell 1, which is convenient for wiring and wiring, and also enables the bottom surface of the fixed seat 201 to extend into the sliding piece 203 during upward movement of the sliding piece 203 to extrude air, so as to facilitate electric breakdown of air in a manner of gradually shortening the distance between the first terminal post 204 and the second terminal post 205. The guide 202 is two or more guide rods fixed vertically in the shell 1, and the side surface of the sliding piece 203 is provided with a guide hole, so that the driving mechanism 206 can drive the sliding piece 203 to slide in the up-down direction when the sliding piece 203 moves. The sliding piece 203 is in a rectangular frame shape, the top surface is open, and the second terminal post 205 is fixed on the sliding piece 203 in an L shape. The driving mechanism 206 is arranged on the side wall of the shell 1 below the sliding piece 203, and opening the driving mechanism 206 drives the sliding piece 203 to move up and down, so that the fixed voltage can electrically breakdown the air between the two terminal posts, and the smoke concentration is fed back according to the order of breakdown.

[0058] In other technical solutions, each electric breakdown mechanism 2 shares one driving mechanism 206.

[0059] In the embodiment, the fixed seat 201 is provided with an air passing hole;

[0060] The sliding piece 203 is hollowly arranged, and the side surface of the sliding piece 203 close to the fixed seat 201 is provided with an opening, the shape of the opening is matched with the shape of the fixed seat 201, and the fixed seat 201 is used for covering the opening.

[0061] In the technical solution, the bottom plane of the fixing seat 201 is provided with a strip-shaped air passing hole penetrating up and down, so that the internal gas can overflow through the air passing hole when the top surface of the fixing seat 201 covers the sliding piece 203, and the internal and external air pressures can be balanced.

[0062] In some technical solutions, the original air in the sliding piece 203 is squeezed out by the mutual approach of the fixing seat 201 and the sliding piece 203, so that new air can be inhaled for subsequent breakdown signal measurement, and the influence of the original air in the sliding piece 203 on the measurement result is reduced. In another technical solution, the air exchange hole is arranged on the side wall of the sliding piece 203 in the direction from one end of the shell 1 to the other end, so that the gas shell 1 directly flows in and out through the side surface of the sliding piece 203.

[0063] In the embodiment, a gap is left between the fixing seat 201 and the shell 1.

[0064] In the technical solution, gaps are left between the front and rear sides of the fixing seat 201 and the front and rear sides of the inner side wall of the shell 1, so that the gas can still flow through the shell 1 when the sliding piece 203 and the fixing seat 201 act, and new gas can be directly inhaled when the sliding piece 203 and the fixing seat 201 are separated, so as to improve the accuracy of the measurement result.

[0065] In the embodiment, the driving mechanism 206 includes:

[0066] The rotating shaft 207 is rotatably arranged in the shell 1;

[0067] The cam 208 is fixed on the rotating shaft 207;

[0068] The motor 209 is connected with the rotating shaft 207 and is used to drive the rotating shaft 207 to rotate.

[0069] In the technical solution, the rotating shaft 207 is horizontally rotatable in the left-right direction in the shell 1, the cam 208 is fixed on the rotating shaft 207 and corresponds to the bottom surface of the sliding piece 203, and the motor 209 is fixedly connected with the rotating shaft 207. The motor 209 drives the rotating shaft 207 to reciprocate, so as to drive the sliding piece 203 to move up and down.

[0070] In some technical solutions, the bottom surface of the sliding piece 203 is provided with a guide block, and the outer surface of the cam 208 is provided with a guide groove, so that the sliding piece 203 and the cam 208 are always surface-fittingly connected, and the possibility that the sliding piece 203 cannot fall due to its own gravity in the foregoing solution is eliminated.

[0071] In the embodiment, it further includes:

[0072] The flow guide 101 is provided with two symmetrical ends of the shell 1, the hollow of the flow guide 101 is provided with a through hole, and the end face area of the flow guide 101 away from the shell 1 is greater than the cross-sectional area of the shell 1.

[0073] In the technical solution, the flow guide 101 is symmetrically fixed on the left and right sides of the shell 1, the top surface of the flow guide 101 is provided with a plane, which is convenient for fixing the shell 1 on the top surface of the indoor, and the whole flow guide 101 is provided with a frustum shape, which is convenient for improving the gas entering capacity of the front and back sides and the lower side of the shell 1, improving the gas density in the shell 1, and generating the electric signal during the measurement.

[0074] The above has described the embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments.
