Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a fire extinguishing device in a closed environment. Background Art

[0002] The characteristics of fires in closed environments are: fires in closed environments are difficult to detect, and cannot be taken seriously and extinguished in the first place. Therefore, they pose a greater safety hazard and often have already caused serious damage to property and objects in the environment when they are discovered.

[0003] The power distribution cabinet is the final equipment of the power distribution system. Its internal core components are all operated in a closed environment composed of an outer shell. The closed environment integrates electrical components for power distribution, such as: air switches, circuit breakers, various types of knife switches, terminal blocks, thermal relays, time relays, fuses and other electronic components. The operation of electronic components will generate heat, and they are prone to aging after long-term use. They are easily affected by static electricity when operating in a dry environment. The above factors may cause fire inside the power distribution cabinet. Once a fire occurs in the power distribution cabinet that is in a closed state under normal circumstances, on the one hand, it is impossible to detect and take fire-fighting measures in the first time, and on the other hand, the internal electronic components will be burned, causing significant losses. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned prior art, the present application provides a fire extinguishing device in a closed environment. The fire extinguishing device is equipped with a perfluorohexanone fire extinguishing module to extinguish the fire and protect the electronic components as soon as possible, and is also equipped with a monitoring component to monitor the fire in time and send it to the client via the cloud to achieve the purpose of alarm.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] A fire extinguishing device in a closed environment, the fire extinguishing device is arranged in a fire extinguishing object with a closed environment formed inside, and flammable components are installed inside the fire extinguishing object. The fire extinguishing device includes a monitoring component arranged inside the fire extinguishing object for monitoring fire, a fire extinguishing module for generating perfluorohexanone gas, and a thermistor for triggering the fire extinguishing module, one end of the thermistor is connected to the fire extinguishing module, and the other end of the thermistor is arranged around the flammable component.

[0007] Furthermore, the fire extinguishing object is a power distribution cabinet, the flammable component is an electrical component module arranged inside the power distribution cabinet, and the monitoring component is a smoke alarm.

[0008] Furthermore, it also includes a plurality of wire troughs arranged around the flammable components, the monitoring component is arranged on the top of the distribution cabinet, the fire extinguishing module is arranged on the side wall of the distribution cabinet, one end of the thermal wire is connected to the fire extinguishing module, and the other end of the thermal wire passes through the wire trough and is arranged around the flammable components.

[0009] The beneficial effects of the utility model are as follows:

[0010] Compared with the prior art, the utility model aims to achieve the purpose of rapid and automatic fire extinguishing by setting a thermal wire around the important parts (electrical component modules) with fire hazards, connecting and triggering the perfluorohexanone fire extinguishing module. The smoke alarm monitors and sends a signal to the client remotely in the first time, so that the staff can detect the fire and take action in the first time.

[0011] Compared with the existing technology, the traditional fire extinguishing solution for distribution cabinets is based on aerosol fire extinguishers, which are characterized by some residues after fire extinguishing and are not easy to clean; while the fire extinguishing solution of the utility model is based on perfluorohexanone, which is an environmentally friendly fire extinguishing agent that will not cause secondary pollution, and has a simpler structure, is easy to repair and maintain, and can be reused without residue on site.

[0017] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0018] The utility model provides a fire extinguishing device in a closed environment, aiming to provide a solution for automatic fire extinguishing processing, fire alarm and protection of important components in a closed environment.

[0019] like Figures 1 to 4As shown, specifically, the environment in which the fire extinguishing device provided by the utility model is set is: it includes a fire extinguishing object 1 with a closed environment formed inside, and a flammable component 2 is installed inside the fire extinguishing object 1; the fire extinguishing device includes a monitoring component 3 arranged inside the fire extinguishing object 1 for monitoring the fire, a fire extinguishing module 4 for generating perfluorohexanone gas, and a thermistor 5 for triggering the fire extinguishing module 4, one end of the thermistor 5 is connected to the fire extinguishing module 4, and the other end of the thermistor 5 is arranged around the flammable component 2.

[0020] Through the above technical solution, the fire extinguishing object 1 is a closed environment, which is equipped with flammable components 2 that have fire risks or require special protection. The flammable components 2 can be the source of fire or the components that need to be protected. By setting the thermal wire 5 around the flammable component 2, when a fire occurs, the flame ignites the thermal wire 5, and the thermal wire 5 starts the gas-producing component in the module. The gas-producing component starts quickly to produce high-pressure gas, and the injection component of the perfluorohexanone fire extinguishing device is opened. The perfluorohexanone fire extinguishing agent is instantly pushed out of the module by the high-pressure gas, and the entire internal space is flooded through the atomizing nozzle, thereby achieving fire extinguishing. When a fire occurs, the monitoring component 3 sends a signal to the client.

[0021] In some embodiments, the fire extinguishing object 1 is a power distribution cabinet, the flammable component 2 is an electrical component module arranged inside the power distribution cabinet, and the monitoring component 3 is a smoke alarm. It also includes four wire ducts 6 arranged around the flammable component 2, the smoke alarm is arranged on the top of the power distribution cabinet, the fire extinguishing module 4 is arranged on the side wall of the power distribution cabinet, one end of the thermal wire 5 is connected to the fire extinguishing module 4, and the other end of the thermal wire 5 passes through the wire duct 6 and is arranged around the flammable component 2.

[0022] It should be noted that, in other embodiments, the application scenarios of the fire extinguishing device provided by the utility model include but are not limited to power distribution cabinets and electrical component modules.

[0023] Working principle of the utility model: when in use, the utility model sends a fire alarm to the client in the first time through the smoke alarm connected to the cloud to attract attention and take action. The technology of sending a fire alarm to the client through the smoke alarm connected to the cloud is a conventional technology in the field, and this application does not make any protective limitation to this.
