[0006] When using a mine temperature measurement optical fiber hotspot detection fire extinguishing device in the technical solution, the external electric ball valve controls the liquid inside the fire-fighting pipe to enter the main pipe in a controlled manner, and the liquid is sprayed out through the connecting pipe and the nozzle body. The displacement distance of the connecting rod and the nozzle body is controlled according to the pressurization pressure of the external liquid pump on the liquid. When the liquid is sprayed through the nozzle body, the liquid is sprayed in the form of water mist, and when the pressure of the liquid is greater than the spring force, the connecting pipe is pushed out of the shunt pipe, so that the liquid inside the shunt pipe is sprayed out through the gap between the shunt pipe and the connecting pipe, and the liquid is sprayed in the form of a water column.

[0008] Preferably, a sealing ring is fixedly attached to the outer wall of the connecting pipe, and the sealing ring contacts the inner wall of the diversion pipe. The sealing ring ensures the sealing between the connecting pipe and the diversion pipe.

[0009] Preferably, a movable hole is provided inside the limit block, and the connecting rod is located inside the movable hole. The movable hole ensures the smoothness of horizontal movement of the connecting rod inside the limit block.

[0010] Preferably, a spring is provided on the outer wall of the connecting rod, and one end of the connecting rod is elastically connected to the outer wall of the limit block through the spring. The spring force maintains the relative position stability of the connecting rod.
