Technical Field

[0001] The utility model relates to the technical field of fire safety, and specifically to a heptafluoropropane fire extinguishing device with multi-mode switching. Background Technique

[0002] A fire extinguishing device is a device that removes fuel, oxygen, and heat at the fire source simultaneously through chemical, physical, or mechanical means, etc., so as to achieve the purpose of extinguishing fire.

[0003] The patent with the publication number CN212679901U discloses a push-cart type multi-functional fire extinguisher, including a vehicle body. One side of the top of the vehicle body is fixedly connected with a mounting plate. A fire extinguisher tank is arranged on the top of the mounting plate. A sliding plate is arranged on one side of the mounting plate. The sliding plate is slidably connected with the vehicle body. An installation column is fixedly connected to the top of the sliding plate. A spray gun is fixedly connected to the top of the installation column. A connecting pipe is arranged between the spray gun and the fire extinguisher tank. The spray gun and the fire extinguisher tank are communicated through the connecting pipe. A fixing mechanism is arranged at the bottom of the vehicle body. The fixing mechanism includes a fixing groove.

[0004] Although the push-cart type multi-functional fire extinguisher generates a recoil force while extinguishing the fire through the spray gun, which pushes the installation column to move, and then pushes the sliding plate to move, thereby pushing the movable plate to press down, increasing the pressure of the fixing feet on the ground, improving the friction between the fixing feet and the ground, avoiding the vehicle body from sliding, and also avoiding users from being burned by high temperature when approaching the high temperature fire source for a long time, it does not have an automatic fire extinguishing function and cannot give a fire alarm.

The lifting ring 10 is used to directly suspend the tank body 1 on the wall surface, and the feet 11 can fix the tank body 1 on the wall surface by screws through their mounting holes.

[0036] In this embodiment, the end face of the square box 21 away from the tank body 1 is open, which is convenient for installing electronic components in the square box 21. A horizontal sliding groove is provided on the inner wall of the square box 21 near the open end. A cover plate 22 is slidably connected in the horizontal sliding groove. The cover plate 22 is used to protect the electronic components in the square box 21, and a number of round through holes for heat dissipation and connecting circuits are provided on the side wall of the square box 21 and the cover plate 22.

[0037] In this embodiment, a slider 210 is integrally formed on the outer side wall of the end face of the square box 21 away from its open end. The slider 210 is in the shape of a frustum of a pyramid. A notch adapted to the shape and size of the slider 210 is provided at the bottom end of the bottom plate 20, which facilitates the quick disassembly and assembly between the square box 21 and the bottom plate 20.

[0038] In this embodiment, the spraying device 9 is composed of a container pipe 90 directly and communicatively inserted into the center of the bottom surface of the tank body 1 from top to bottom, a solenoid valve 91 communicatively sleeved on the outer arc side wall of the container pipe 90, and a nozzle 92 communicatively inserted into the bottom end surface of the container pipe 90.

Among them, the single-chip microcomputer 3 is the control module. When the smoke sensor 5 detects a fire, the buzzer 6 will give an alarm to remind the surrounding people to evacuate to a safe place urgently. Then the single-chip microcomputer 3 will drive the solenoid valve 91 to release the gas of the heptafluoropropane fire extinguishing device to extinguish the fire. At the same time, an infrared receiving module 4 is installed in this fire extinguishing device to receive the infrared signal of the infrared remote control, to prevent the fire extinguishing device from failing to take corresponding measures in the first time when an emergency occurs, so as to facilitate manually controlling the fire extinguishing device with the infrared remote control.
