[0021] Reference Figure 1-4 This utility model proposes a multi-tube rack-type fire extinguishing device, comprising: an outer casing 1, a spray pipe 2 disposed inside the outer casing 1, and a fire extinguishing agent spraying component 4, wherein:

[0022] The outer casing 1 has a spray end and mounting holes opened at the spray end. There are multiple spray pipes 2, and each spray pipe 2 independently encapsulates the extinguishing agent and achieves fluid convergence through a manifold valve 3. Specifically, the spray pipe 2 includes a pipe tube 21, a front end cap 22 set at one end of the pipe tube 21, a rear end cap 23 set at the other end of the pipe tube 21, and a spray port set on the front end cap 22 for the extinguishing agent encapsulated inside to be sprayed out; the manifold valve 3 has a convergence channel set inside it and several inlets communicating with the convergence channel, and a pressure feedback component 5 is installed at one end of the convergence channel, and the other end is the output end; the manifold valve 3 is installed on the front end cap 22 of each spray pipe 2, and each of its inlets corresponds to and is connected to the spray port of each spray pipe 2.

[0023] The extinguishing agent spraying component 4 is installed in the mounting hole and connected to the output end of the manifold valve 3. The extinguishing agent spraying component 4 includes at least the following three activation methods:

[0024] like Figure 1 As shown, in Method 1: the extinguishing agent spraying component 4 includes an atomizing nozzle A4-11, a first end plug 4-12, a second end plug 4-13, and a heat-sensing glass bulb 4-14. The inlet of the atomizing nozzle A4-11 is connected to and conducts through the output end of the manifold valve 3. The nozzle of the atomizing nozzle A4-11 is located outside the outer casing 1. A chamber is provided inside the atomizing nozzle A4-11 between its inlet and nozzle. The first end plug 4-12, the second end plug 4-13, and the heat-sensing glass bulb 4-14 are all located within the chamber. The heat-sensing glass bulb 4-14 is located between the first end plug 4-12 and the second end plug 4-13, and its two ends abut against the first end plug 4-12 and the second end plug 4-13 respectively, so that the first end plug 4-12 and the second end plug 4-13 block the inlet and nozzle of the atomizing nozzle A4-11 respectively. During operation, when the temperature-sensing glass bulb 4-14 reaches the set temperature, it automatically breaks. At this time, the first end plug 4-12 and the second end plug 4-13 lose the constraint of the temperature-sensing glass bulb 4-14, and the inlet and outlet of the atomizing nozzle A4-11 open. The extinguishing agent in the spray pipe 2 is atomized and sprayed out by the nozzle under its internal pressure to carry out full immersion fire extinguishing.

[0025] like Figure 2As shown, Method 2: The extinguishing agent spraying component 4 includes an atomizing nozzle B4-21 and a puncture valve 4-22. The atomizing nozzle B4-21 is connected to the output end of the collector valve 3 via the puncture valve 4-22. The specific principle is as follows: the inlet of the puncture valve 4-22 is connected to the output end of the collector valve 3, and the outlet of the puncture valve 4-22 is connected to the atomizing nozzle B4-21. The sealing diaphragm inside the puncture valve 4-22 is between its inlet and outlet. When the puncture valve 4-22 reaches the puncture condition, the puncture rod of the puncture valve 4-22 punctures the sealing diaphragm, so that the extinguishing agent in each spray pipe 2 enters the atomizing nozzle A4-11 from the output end of the collector valve 3 and is sprayed out by the atomizing nozzle B4-21.

[0026] like Figure 3 As shown, Method 3: The extinguishing agent spraying component 4 includes a fire detection tube, wherein the fire detection tube is connected to the output end of the manifold valve 3. When the fire detection tube reaches the set temperature, it automatically breaks. At this time, the extinguishing agent in the spray pipe 2 is sprayed out through the rupture of the fire detection tube under its internal pressure, and performs full immersion fire extinguishing.

[0027] In practical use, different structures of fire extinguishing agent spraying components 4 are selected according to the internal environment of the cabinet and actual needs. Different structures of fire extinguishing agent spraying components 4 have different activation methods, and different activation methods have different response speeds and applicable ranges to meet the fire extinguishing needs in different scenarios.

[0028] In addition, in this embodiment, a connector 6 is installed on the outer casing 1 for connecting external devices. The outer casing 1 has a mounting part on its exterior for installation, and the mounting part has mounting holes. During installation, the device can be installed with the cabinet by engaging bolts through the mounting holes on the mounting part.

[0029] The extinguishing agent used in this embodiment is perfluorohexanone, which has advantages such as high extinguishing efficiency, no damage to the battery module, and environmental friendliness. Compared with traditional extinguishing agents, perfluorohexanone can reduce the temperature of the fire source more quickly and inhibit the spread of flames, while not causing corrosion or damage to the internal circuits and components of the battery module, ensuring the normal use of the battery module after the fire is extinguished. In addition, perfluorohexanone leaves very little residue and has very little environmental pollution, meeting the requirements of modern environmental protection concepts.

[0030] In this embodiment, the spray pipe 2 is made of aluminum profile. Aluminum profile has the advantages of low cost and strong plasticity, and has good compatibility with perfluorohexanone fire extinguishing agent.

[0031] In addition, the multi-tube rack-type fire extinguishing device proposed in this utility model also includes a safety valve 7 and a pressure gauge 8, with the safety valve 7 installed on the rear end cover 23 of one of the spray pipes 2 and the pressure gauge 8 installed on the rear end cover 23 of the other spray pipe 2.

[0032] As can be seen from the above, this utility model adopts a multi-pipe design and merges the pipes into a single channel through the manifold valve 3. This allows the fire extinguishing agent to continue to be delivered through other pipes even if one pipe is blocked or damaged, ensuring the continuous fire extinguishing work. This multi-pipe design greatly improves the safety and reliability of the fire extinguishing device in emergency situations, and the point-to-point fire extinguishing response is rapid. The sprayed fire extinguishing agent is close to the fire source and can directly extinguish the fire in its bud.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
