Oppositely arranged stroke grooves 6 are provided in the long plate 4. Rows of teeth 7 are provided in the two stroke grooves 6.

[0026] Through the above structure, the long plate 4 can be fixedly installed in the mine. How to assist the mine workers to take emergency measures in time when the gas concentration is abnormal, the specific structure is as follows:

[0027] As Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the reciprocating detection mechanism 8 includes a driving box 11 fixedly connected to the upper end of the gas detector main body 9 and support rods 16 fixedly connected to both sides of the gas detector main body 9. Support plates 17 are fixedly connected to both sides of the support rods 16. Rotating shafts 18 are rotatably provided on both sides of the support plates 17. Driven gears 14 are fixedly connected to one end of the rotating shafts 18 relative to the support plates 17.

A double-shaft motor for driving the two driven gears 14 to rotate synchronously is provided in the driving box 11. The output ends of the double-shaft motor penetrate one side of the driving box 11. The output ends of the double-shaft motor are fixedly connected with driving gears 12. Synchronous belts 13 are provided on the driving gears 12 and cooperate with the driven gears 14. Limiting side plates 15 for cooperating with the synchronous belts 13 are fixedly connected to one end of the driven gears 14 and the driving gears 12. The rotating shafts 18 penetrate the limiting side plates 15 at one end of the driven gears 14, and the limiting side plates 15 can play a role in limiting the synchronous belts 13. A wireless data transmission module and a control module electrically connected to the gas detector main body 9 and the mobile terminal are provided in the driving box 11.

[0028] Through the above structure, the real-time data of the gas concentration can be transmitted remotely to the mobile terminal of the staff in real time, and the control module can remotely send alarm data when the data is abnormal.

[0029] Embodiment 2

[0030] As Figure 2 、 Figure 4 and Figure 5 shown, not less than one warning light 5 is provided on the long plate 4 and is evenly arranged. The warning light 5 is electrically connected to the control module. The warning light 5 is a safety light used in the mine that can prevent the explosion of the mixed gas.

[0032] When the present utility model is specifically implemented, first select a suitable position before use, and fixedly install the two mounting plates on the top wall in the mine through the cooperation of expansion screws and mounting holes.
