[0023] How it works

[0024] In the present invention, when in use, the pipe network 1 is laid inside the land, the base frame 31 is fixed to the ground, the pipe network 1 is connected to the external water source pipeline, the water source enters the first delivery pipe 11 and the second delivery pipe 12, and enters the fire extinguishing nozzle assembly 3 through the connecting pipe 2. The rotating thermal imaging assembly 4 detects the direction of the fire through the principle of thermal imaging, so that the fire extinguishing nozzle assembly 3 sprays water towards the direction of the fire, which plays a role in fire prevention and fire extinguishing. The water valve, motor 36, and thermal imager 44 in the nozzle 35 are all connected to the external control device. When water is sprayed on the forest or grassland for fire prevention or water extinguishing, the fire extinguishing nozzle assembly 3 is connected to the external control device. When a fire occurs, the water valve of the sprinkler head 35 is opened, and the motor 36 drives the rotating shaft 39 to rotate, which synchronously drives the first driven gear 34 and the second driven gear 42 to rotate through the driving gear 38, thereby driving the sprinkler head 35 to rotate, so that the sprinkler head 35 sprays water in all directions. When the second driven gear 42 rotates, it drives the waterproof cover 43 and the thermal imager 44 to rotate, so that the thermal imager 44 detects the direction of the fire. As the waterproof cover 43 rotates, the wiper 45 scrapes off the water outside the waterproof cover 43 to protect the thermal imager 44 and reduce the impact of the sprayed water on the accuracy of the detection of the thermal imager 44.
