Problems solved by technology

[0003] When a fire breaks out in an underground project, the smoke quickly spreads underground, so it is necessary to evacuate the underground staff in a timely manner. At present, the evacuation of the staff is mostly guided by indicator lights, but when a fire breaks out underground, the underground temperature is high. It is easy to cause damage to the indicator light. In addition, when installing and laying the indicator light, a large number of lines need to be laid, and the operation is cumbersome. The damaged indicator light cannot be repaired in time, resulting in unclear guidance for underground workers when a fire occurs

Embodiment 1

[0022] refer to figure 1 , a fire indication and escape equipment for underground engineering, comprising an indication box 1, a luminous cavity 2 is provided at the lower end of the indicator box 1, and the luminous cavity 2 is filled with neon gas, further, when a low-voltage discharge is performed in the neon gas, the neon gas will Produces orange-red light, the bottom of the light-emitting chamber 2 is provided with a frame opening 3, the inner wall of the frame opening 3 is fixedly connected with a transparent plate 4, and the indicator box 1 is provided with a slide chamber 5, which is sealed and slidably connected with a magnetic slide Plug 6, it should be noted that the inner wall of the slider cavity 5 is symmetrically provided with through holes communicating with the outside world to balance the air pressure change generated when the magnetic slider 6 slides in the slider cavity 5, and the inner wall of the slider cavity 5 is embedded with There is a helical coil 7,...

Embodiment 2

[0026] refer to Figure 2-3 , and the difference from the first embodiment is that a one-way suction pipe 15 is connected under the inner wall of the slide chamber 5, and an air storage chamber 16 is opened in the indicator box 1, and the inner wall of the slide chamber 5 connects with the air storage chamber 16 through a one-way air guide pipe 17 The inner wall is connected. It should be noted that the one-way suction pipe 15 only allows gas to enter the slide chamber 5 from the outside, and the one-way air guide pipe 17 only allows gas to enter the air storage chamber 16 from the slide chamber 5. The side wall of the frame opening 3 An annular chamber 19 is provided, and the inner wall of the gas storage chamber 16 is connected to the annular chamber 19 through a connecting pipe 18. A pressure relief valve is installed in the connecting pipe 18. The inner wall of the annular chamber 19 is provided with a plurality of air injection holes 20 inclined toward the transparent plat...

Abstract

The invention discloses fire indication escape equipment for underground engineering. The equipment comprises an indication box, a light-emitting cavity is formed in the lower end of the indication box; the light-emitting cavity is filled with neon. A frame opening is formed in the bottom in the light-emitting cavity; a transparent plate is fixedly connected to the inner wall of the frame opening,a sliding plug cavity is formed in the indication box, a magnetic sliding plug is connected into the sliding plug cavity in a sealed and sliding mode, a spiral coil is embedded into the inner wall ofthe sliding plug cavity, two discharge needles are symmetrically and fixedly connected to the inner wall of the light-emitting cavity, and the two ends of the spiral coil are connected with the two discharge needles in a coupled mode respectively. The magnetic sliding plug slides up and down on the inner wall of the sliding plug cavity; the spiral coil cuts the magnetic induction line and generates induction current, the tips of the two spray points respectively gather a large amount of positive and negative charges, and according to the point discharge phenomenon, when the charges on the spray points gather to a certain degree, point discharge occurs between the spray points, so that neon can emit orange red light after being broken down, and then escape indication is performed.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to a fire indicating escape device for underground engineering. Background technique [0002] Underground engineering refers to the underground civil engineering that goes deep below the ground to develop and utilize underground space resources. In order to meet production needs during the construction of underground engineering, it is required to lay a large number of equipment and lines in underground engineering. Due to the poor air circulation and The heat generated during the construction process is high, causing fires to occur in underground engineering. [0003] When a fire breaks out in an underground project, the smoke quickly spreads underground, so it is necessary to evacuate the underground staff in a timely manner. At present, the evacuation of the staff is mostly guided by indicator lights, but when a fire breaks out underground, the underground tempera...
