One end protrudes from the top of the protective shell 1, and an atomizing nozzle 204 is installed at the end of the water supply pipe 2 away from the water supply port 102. The cross-section of the protective shell 1 is L-shaped, and the water supply pipe 2 is a hollow tubular structure. When the spring 203 is in an extended state, it pushes the height of the slip ring 201 to increase, so that the length of the water supply pipe 2 entering the water supply port 102 increases, and the limiting protrusion 202 can move in the slot 101, and when it moves to the lowest point, it drives the slip ring 201 to deflect, so that the position of the slip ring 201 in the protective shell 1 is fixed, so that the atomizing nozzle 204 connected to one end of the water supply pipe 2 protrudes from the protective shell 1, which is not easily damaged during transportation, thereby facilitating the detection of flames.

[0031] The water supply pipe 2 is connected to the guide groove 6 through the connecting shaft 5. A photometer body 7 is provided at one end of the guide groove 6. The photometer body 7 is fixedly installed in the protective shell 1, and one end of the guide groove 6 extends into the guide groove 6. A sampling groove is provided on the outside of the guide groove 6 to cooperate with the atomizing nozzle 204. The atomized sample with flame components processed by the atomizing nozzle 204 can be transported to the photometer body 7. The photometer body 7 is an ICP spectrometer.

[0032] A positioning plug 3 is provided at one end of the spring 203 away from the slip ring 201. The positioning plug 3 is fixedly installed on the side of the protective shell 1 away from the card slot 101. The water supply pipe 2 passes through one end of the positioning plug 3 and is connected to the atomizing nozzle 204. The positioning plug 3 can be clamped on the bottom of the protective shell 1, and can limit the angle of the water supply pipe 2 when it moves, thereby avoiding the angle of the water supply pipe 2 from being offset, affecting the atomization treatment effect.

[0033] An atomizing tank 8 is fixedly installed on one side of the protective shell 1 close to the water supply port 102. A conduit 9 is provided in the atomizing tank 8. One end of the conduit 9 passes through the water supply port 102 and is connected to the water supply pipe 2 and communicates with the water supply pipe 2. The atomizing tank 8 stores atomizing liquid mixed with argon gas and is controlled by a solenoid valve. The atomizing liquid in the atomizing tank 8 can be transported to the water supply pipe 2 through the conduit 9, so that the atomizing nozzle 204 can atomize and sample the flame components.

[0034] A socket 103 is also provided on one side of the protective shell 1 near the water supply port 102. A plug 104 is movably connected to the protective shell 1. One end of the plug 104 extends into the socket 103. The socket 103 runs through the entire protective shell 1 and the angle between it and the plug 104 is ninety degrees.

[0035] A column 4 is provided on the side of the protective shell 1 away from the water supply pipe 2. The column 4 includes a ground plug 401. One end of the ground plug 401 is provided with a threaded shaft 402. The ground plug 401 is threadedly connected to the threaded shaft 402. A thread that matches the threaded shaft 402 is opened in the middle of the ground plug 401, and the end of the ground plug 401 away from the threaded shaft 402 is relatively sharp and can be inserted into the soil in the forest, thereby completing the arrangement of different fire prevention points.

[0036] A positioning hole 403 is provided at one end of the threaded shaft 402 away from the ground plug 401. The positioning hole 403 and the plug 104 are adapted to each other, and the threaded shaft 402 is connected to the socket 103 through the plug 104. The threaded shaft 402 can be inserted into the socket 103 in the protective shell 1, and the plug 104 can be inserted into the socket 103 and pass through the positioning hole 403, so that the protective shell 1 can be assembled with threaded shafts 402 at different heights, thereby meeting the layout requirements of fire protection points at different heights.

[0037] During transportation, the spring 203 in the extended state pushes the slip ring 201 to rise in the protective shell 1, and the limiting protrusion 202 on the slip ring 201 moves under the restriction of the card slot 101 in the protective shell 1, so that the water supply pipe 2 is not easy to deviate during movement. At the same time, the atomizing nozzle 204 connected to the water supply pipe 2 located in the water supply port 102 is completely retracted into the protective shell 1, so that when arranging multiple fire prevention points, the atomizing nozzles 204 are not easy to contact each other and cause wear, thereby ensuring the smooth arrangement of the fire prevention points. When arranging the fire prevention points, by rotating the threaded shaft 402, the length of the threaded shaft 402 threadedly connected to the ground plug 401 in the ground plug 401 changes, and the sharp end of the ground plug 401 is inserted into the forest soil, and the threaded shaft 402 is passed through The plug 103 is inserted into the protective shell 1, and the plug 104 is passed through the positioning hole 403 and snap-fitted with the plug 103, thereby fixing the protective shell 1 on the top of the threaded shaft 402, thereby meeting the layout requirements of fire protection points at different heights. When performing flame detection, the atomized liquid with argon stored inside the atomizing tank 8 is controlled to be released through the solenoid valve, so that the atomized liquid is transported to the water supply pipe 2 through the conduit 9, so that the atomizing nozzle 204 can atomize and sample the flame components, and send the treated atomized sample solution into the photometer body 7 through the guide groove 6 for detection. The photometer body 7 indirectly provides certain characteristic information of the flame by analyzing the spectral signals of the elements in these samples, and provides warnings to forest rangers through electrical signals to the computer terminal.
