Problems solved by technology

[0003] In areas such as power distribution cabinets and warehouses where operators seldom discover fires in time, it is difficult for operators to extinguish the fire in time after a fire occurs. At the same time, due to the limited fire extinguishing capacity of a single fire extinguisher, the fire is prone to secondary re-ignition. , causing a huge threat to property and life

Embodiment 2

[0051] refer to image 3 The difference between this embodiment and Embodiment 1 is that each fire extinguishing pipe 21 is connected with an electronic control valve 24 at the position close to the fire extinguisher 1, there are multiple temperature sensors 32, and the electronic control valve 24 is respectively connected with the adjacent temperature sensor. 32 is electrically connected, and when the temperature received by a temperature sensor 32 exceeds a threshold value, the electronically controlled valve 24 electrically connected thereto opens. When a fire occurs, the temperature is transmitted to the temperature sensor 32, and the electronic control valve 24 electrically connected to the corresponding temperature sensor 32 is opened, so as to extinguish the fire at the corresponding position.

[0052] working principle:

[0053] When a fire occurs, the temperature sensor 32 senses the occurrence of the fire, and the electronic control valve 24 electrically connected w...

Embodiment 3

[0055] refer to Figure 4 The difference between this embodiment and Embodiment 1 is that the fire extinguishing pipe 21 is a fire detection pipe.

[0056] working principle;

[0057] When a fire occurs, the temperature is sent to the temperature sensor 32. When the temperature sensor 32 detects that the temperature is higher than the threshold value, the temperature sensor 32 sends a pulse to the high-energy substance in the fire extinguisher 1 through the controller 31 and the trigger line 33, so as to send the high-energy substance to the fire extinguisher 1. Ignition, the high-energy substance releases a large amount of gas and drives the piston 11 to extrude the fire extinguishing agent from the fire extinguisher 11, the fire extinguishing pipe 21 is burned by the flame, and the fire extinguishing pipe 21 is ruptured under the action of the pressure to release the fire extinguishing agent, so as to timely extinguish the fire. Carry out fire fighting.

Abstract

The invention discloses a fire extinguishing system with a repeated fire extinguishing function. The fire extinguishing system comprises a fire extinguisher, a spraying assembly and a temperature sensing detection assembly. More than two chambers are arranged in the fire extinguisher; the spraying assembly comprises a fire extinguishing pipe, the fire extinguishing pipe is connected with a fire extinguisher, and each cavity communicates with the fire extinguishing pipe through a channel; the temperature sensing detection assembly comprises a controller and a temperature sensor, the temperature sensor is electrically connected with the controller, the controller is connected with trigger lines, the number of the trigger lines is more than two, one end, far away from the temperature sensor, of each trigger line is connected with a cavity in the fire extinguisher, and the temperature sensor is electrically connected with the controller. The trigger line is used for controlling the fire extinguisher to spray a fire extinguishing agent. The fire extinguishing system with the repeated fire extinguishing function, provided by the invention, can be used for carrying out fire extinguishing treatment on a fire in time, so that the phenomenon that the fire is re-combusted for multiple times is effectively avoided, and the safety of a fire-extinguished device is improved.

Description

technical field [0001] The present application relates to the field of fire extinguishing devices, and in particular, to a fire extinguishing system with a repetitive fire extinguishing function. Background technique [0002] A fire extinguisher is a fire extinguishing tool. Chemicals are placed in the fire extinguisher to put out a fire. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fire may occur. Different types of fire extinguishers are filled with different components and are specially designed for different fire causes. There are many types of fire extinguishers, which can be divided into portable and cart types according to their moving methods; according to the power source of driving fire extinguishing agents, they can be divided into: gas storage cylinder type, pressure storage type, and chemical reaction type; Agents can be divided into: foam, dry powder, halogenated alkanes, carbon dioxide, ...
