Description

Technical Field

[0001] The invention relates to a fire extinguishing device, in particular to an environmentally friendly embedded fire extinguishing device, belonging to the technical field of fire extinguishing equipment. Background Art

[0002] At present, conventional gas fire extinguishing systems are usually used to protect large enclosed spaces containing a large number of valuable cabinets. That is, when a fire occurs in a cabinet in the protection area, all the sprinklers in the entire large room will spray fire extinguishing agents to extinguish the fire. The engineering cost is high, the cost of each fire extinguishing is high, and the secondary recovery time of the fire extinguishing system is long. Therefore, embedded fire extinguishing equipment came into being, providing a more efficient and economical solution for cabinet protection. These embedded fire extinguishing equipment can be cleverly embedded in the interior of the cabinet to achieve accurate and rapid extinguishing of the fire source inside the cabinet. Compared with traditional systems, embedded fire extinguishing equipment not only significantly improves the fire extinguishing efficiency, but also is more energy-saving and environmentally friendly. In particular, the use of heptafluoropropane gas as the fire extinguishing medium not only has excellent fire extinguishing performance, but also better meets the current environmental protection requirements, effectively reducing the impact on the environment.

[0003] A known Chinese authorized patent (Announcement No.: CN217526164U) discloses an embedded intelligent fire extinguishing device, which is built into the top of a closed cabinet. It has a compact structure, occupies a small space, has complete functions, has high fire extinguishing efficiency, and does not cause harm to personnel. Moreover, the fire extinguishing agent is directly sprayed inside the cabinet to reach the fire source, which can extinguish the initial fire faster, prevent the fire from expanding, and reduce economic losses. The embedded fire extinguishing equipment is directly embedded in the cabinet. Although it significantly improves the fire extinguishing efficiency and achieves rapid response and accurate fire fighting to the fire source inside the cabinet, the following problems still exist in the actual fire extinguishing process: Since the nozzle position of the embedded fire extinguishing equipment is relatively fixed, and the cabinet is often densely packed with various electronic equipment, lines and connectors, the layout of these equipment is intricate, forming a lot of obstructions and obstacles. When the fire extinguishing agent is sprayed from the nozzle at a fixed position, it will be blocked by the equipment inside the cabinet, resulting in the fire extinguishing agent being unable to evenly and quickly cover all the fire points, thus affecting the speed and effect of fire extinguishing; Therefore, an environmentally friendly embedded fire extinguishing device is proposed.
