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 h

Example Embodiment

[0021] Example one

[0022] Reference figure 1 , A fire indicating escape device for underground engineering, comprising an indicating box 1. A light-emitting cavity 2 is opened at the lower end of the indicating box 1, and the light-emitting cavity 2 is filled with neon gas. Further, when a low-pressure discharge is performed in the neon gas, the neon gas will The orange-red light is produced. The bottom of the light-emitting cavity 2 is provided with a frame opening 3, the inner wall of the frame opening 3 is fixedly connected with a transparent plate 4, a sliding plug cavity 5 is opened in the indicating box 1, and a magnetic sliding plug is sealed and slidingly connected in the sliding plug cavity 5 Plug 6, it should be noted that the inner wall of the sliding plug cavity 5 is symmetrically provided with through holes communicating with the outside to balance the air pressure changes generated when the magnetic sliding plug 6 slides in the sliding plug cavity 5. The sliding pl...

Example Embodiment

[0025] Example two

[0026] Reference Figure 2-3 The difference from the first embodiment is that a one-way suction tube 15 is connected below the inner wall of the sliding plug cavity 5, an air storage cavity 16 is opened in the indicating box 1, and the inner wall of the sliding plug cavity 5 passes through the one-way air guide tube 17 and the air storage cavity 16 The inner wall is connected. It should be noted that the one-way air suction pipe 15 only allows gas to enter the sliding plug cavity 5 from the outside, and the one-way air guiding pipe 17 only allows gas to enter the air storage cavity 16 from the sliding plug cavity 5, and the side wall of the frame mouth 3 An annular cavity 19 is provided. The inner wall of the gas storage cavity 16 is connected to the annular cavity 19 through a connecting pipe 18, a pressure relief valve is installed in the connecting pipe 18, and the inner wall of the annular cavity 19 is provided with a plurality of jet holes 20 inclined to...

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...
