DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 A high-pressure fine water mist nozzle for fire fighting comprises a mounting seat 1, a water outlet pipe 2 is connected to the mounting seat 1, a blocking rod 3 is movably connected to the pipe mouth of the water outlet pipe 2, a temperature sensor 4 is installed at the bottom of the blocking rod 3, a pushing mechanism 5 is arranged on the mounting seat 1, the pushing mechanism 5 comprises a servo motor 501 arranged on the mounting seat 1, the servo motor 501 is electrically connected to the temperature sensor 4, a threaded rod 502 is connected to the output end of the servo motor 501, a moving ring 503 is threadedly connected to the threaded rod 502, the moving ring 503 is connected to the outer surface of the blocking rod 3, a mounting ring 504 is elastically connected to the moving ring 503, the mounting ring 504 is slidably connected to the blocking rod 3, and a plurality of baffles 505 are rotatably connected to the mounting ring 504, and the other ends of the plurality of baffles 505 are rotatably connected to the bottom end of the blocking rod 3.

[0024] When a fire occurs, the temperature rise of the air is sensed by the temperature sensor 4, triggering the servo motor 501 to work, and the servo motor 501 drives the threaded rod 502 to rotate, so that the moving ring 503 threadedly connected to the threaded rod 502 drives the blocking rod 3 to move synchronously in the direction away from the mounting seat 1, and then the blocking rod 3 moves to the outside of the water outlet pipe 2, so that the water flow in the water outlet pipe 2 can flow out normally for fire extinguishing. When the moving ring 503 moves, it drives the mounting ring 504 to move in the same direction, thereby pushing a plurality of baffles 505 to rotate toward the outside of the blocking rod 3 with the bottom end of the blocking rod 3 as the midpoint. , achieving the effect of spreading the baffles 505. When water flows out of the water outlet pipe 2, it will impact the baffles 505, and the baffles 505 will block the water flow, thereby expanding the spraying area of ​​the water flow, and then effectively expanding the fire extinguishing area; when the fire is extinguished and the temperature drops, the temperature sensor 4 triggers the servo motor 501 again, and the servo motor 501 rotates in the opposite direction, thereby driving the moving ring 503 to move upward through the threaded rod 502, so that the blocking rod 3 moves synchronously and is plugged into the inside of the water outlet pipe 2, and the baffles 505 are retracted, thereby blocking the water outlet pipe 2 again for the next fire extinguishing work.

[0025] Reference Figure 4 In this embodiment, a limiting rod 506 is installed at the bottom of the mounting seat 1, and the moving ring 503 is slidably connected to the limiting rod 506, so that when the threaded rod 502 drives the moving ring 503 to move, the moving ring 503 is restricted by the limiting rod 506 to move only in the vertical direction, thereby limiting the moving direction of the moving ring 503 and ensuring that it can drive the blocking rod 3 to be in or out of the water outlet pipe 2.

[0026] Reference Figure 3-4 In this embodiment, a first spring 507 is installed at the bottom end of the movable ring 503, and one end of the first spring 507 away from the movable ring 503 is connected to the mounting ring 504, so that when the blocking rod 3 moves toward the water outlet pipe 2, the first spring 507 starts to reset and at the same time drives the mounting ring 504 to move toward the movable ring 503, thereby driving a plurality of baffles 505 to close, so as to facilitate continuing to open during the next fire extinguishing operation.

[0027] Reference Figure 4 In this embodiment, a plurality of baffles 505 are rotatably connected to connecting rods 508, and the other end of the connecting rods 508 are rotatably connected to the mounting ring 504, so that when the mounting ring 504 moves downward, it can drive the connecting rods 508 to move synchronously, causing the connecting rods 508 to push the baffles 505 to expand toward the outside of the blocking rod 3, thereby achieving the purpose of opening the plurality of baffles 505.

[0028] Reference Figure 4-5In this embodiment, a support frame 512 is installed at the bottom of the mounting seat 1, and the bottom end of the support frame 512 is directly below the blocking rod 3, and two connecting grooves 509 are provided on the outer curved surface of the blocking rod 3, and two connecting blocks 510 are installed on the movable ring 503, and the connecting blocks 510 are slidably adapted in the connecting grooves 509, and second springs 511 are installed on the two connecting blocks 510, and the bottom ends of the two second springs 511 are connected in the connecting grooves 509, so that the movable ring 503 drives the blocking rod 3 to move downward until it contacts the support frame 512, and the blocking rod 3 is restricted by the support frame 512 and cannot move further. At this time, the movable ring 503 is slidably connected to the blocking rod 3 under the action of the second spring 511 and the connecting groove 509 and is in a downward moving state, thereby pushing the mounting ring 504 to move downward along the direction of the blocking rod 3, so that a number of baffles 505 are opened.

[0029] Reference Figure 4 In this embodiment, the end of the blocking rod 3 close to the water outlet pipe 2 is truncated into a cone shape, and an elastic layer is attached thereto, so that the top end of the blocking rod 3 is easily inserted into the water outlet pipe 2, and the elastic layer thereon increases the friction between the blocking rod 3 and the water outlet pipe 2, making the connection between the two more secure.

[0030] Reference Figure 4 In this embodiment, a mounting groove 513 is provided on the mounting base 1 , and the position of the mounting groove 513 is adapted to the servo motor 501 , so that the servo motor 501 can be installed on the mounting base 1 through the mounting groove 513 , thereby providing space for the installation of the servo motor 501 .
