For example, the patent application No. 202322116577.6, the authorized announcement No. CN220695718U and the name of a storage type external pressure perfluorocyclohexanone fire extinguishing device, the storage of perfluorocyclohexanone extinguishing agent in the disclosed patent adopts the storage type, and one fire extinguishing system only needs one perfluorocyclohexanone extinguishing agent storage tank. Compared with the traditional bottle type perfluorocyclohexanone fire extinguishing device, the number of system bottles is small, the system pipe network is simpler, the work is more reliable, and the application defects of the traditional bottle type external pressure perfluorocyclohexanone fire extinguishing device in large space protection places are solved. However, as described in the foregoing disclosed patent, the existing perfluorocyclohexanone fire extinguishing device needs gas source, multiple pipelines and multiple valve bodies to intervene in the work when realizing the fire extinguishing function, so that the power supply and standby power supply of the fire fighting system are required to be high, and there are problems of complicated installation and high cost. CONTENT OF THE UTILITY MODEL

[0003] The utility model provides a thermal initiator starts to store pressure type perfluorocyclohexanone fire extinguishing device, adopts the thermal initiator to start the storage pressure type perfluorocyclohexanone fire extinguishing device, and the thermal initiator is arranged at the fire hazard position. Once the fire occurs, the flame burns the thermal initiator or the ambient temperature reaches 180 DEG C, the thermal initiator transmits the fire signal to the starting assembly of the device, starts the storage pressure type perfluorocyclohexanone fire extinguishing device and works, and reaches the extinguishing agent cooling effect.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme:

[0005] A thermal initiator starts to store pressure type perfluorocyclohexanone fire extinguishing device, which comprises a storage tank with perfluorocyclohexanone extinguishing agent and nitrogen gas arranged in the inner cavity top of the storage tank, and further comprises:

[0006] A starting assembly is arranged at the open side of the top of the storage tank.

[0007] A release pipe is arranged in communication with the starting assembly at one end and extends to the inside of the perfluorocyclohexanone extinguishing agent in the inner cavity of the storage tank at the other end; and

[0008] A thermal initiator extends outward from the starting assembly and is used to control the working of the starting assembly when the fire occurs.

[0009] Preferably, the one end of the starting assembly away from the storage tank is provided with an extinguishing agent outlet.

[0010] Preferably, the starting component is provided with a pressure detection component, which includes a pressure detector and a pressure gauge disposed on the starting component.

Detailed Implementation

[0021] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: (Refer to...) Figure 1 A thermally activated pressurized perfluorohexanone fire extinguishing device includes a storage tank 10, which contains perfluorohexanone extinguishing agent. Nitrogen gas 20 is also provided at the top of the tank's inner cavity. Further, the device includes an activation assembly, a release pipe 40, and a thermal initiator 50. Specifically, the activation assembly is located on the open top side of the storage tank 10. One end of the release pipe 40 is connected to the activation assembly, and the other end extends into the perfluorohexanone extinguishing agent within the tank's inner cavity. The thermal initiator extends outward from the activation assembly. This device is used to control the activation component in the event of a fire to achieve a cooling effect on the extinguishing agent. During use, the thermal initiator is placed at the location of the fire hazard. Once a fire occurs, if the flames reach the thermal initiator or the ambient temperature reaches 180°C, the thermal initiator will detect the fire and transmit the fire signal to the activation component, activating the pressurized perfluorohexanone fire extinguishing device. The activation component opens the valve channel, and the nitrogen gas in the storage tank drives the perfluorohexanone extinguishing agent to be discharged from the storage tank to the outside of the storage tank through the release pipe. The perfluorohexanone extinguishing agent is then sprayed onto the location of the fire through the outlet of the activation component, thereby achieving fire extinguishing and cooling.

[0023] Reference Figure 1 As a preferred technical solution in this embodiment, in order to facilitate the outward spraying of perfluorohexanone extinguishing agent output through the release pipe 40, an extinguishing agent outlet 310 is provided at the end of the starting component away from the storage tank 10.

[0024] Furthermore, the starting component is equipped with a pressure detection component, which includes a pressure detector 321 and a pressure gauge 322. The pressure detector and pressure gauge can detect and display the pressure value during the operation of the starting component, so as to observe the working status of the thermal initiator starting the storage-type perfluorohexanone fire extinguishing device in real time.

[0025] Reference Figure 2In some embodiments, the activation component includes a main cavity 330, a gas-generating chamber 340, an inlet chamber 350, an outlet chamber 360, and a puncture component. The main cavity 330 is connected to the thermal initiator 50. The gas-generating chamber 340 is located inside the main cavity. The inlet chamber 350 is fixedly located at one end of the main cavity, and the outlet chamber 360 is fixedly located at the other end of the main cavity. The puncture component is located inside the gas-generating chamber, and the puncture component can be activated by the thermal initiator to make the activation component conductive. In this way, when the activation component is activated, the perfluorohexanone extinguishing agent in the storage tank 10 can be delivered out to achieve the fire extinguishing effect.

[0026] Furthermore, a gas-generating agent is provided at one end of the gas-generating chamber 340 near the thermal initiator 50. This gas-generating agent can be ignited when the thermal initiator detects a fire source, thereby generating gas in the gas-generating chamber to drive the puncture component. The puncture component can move along the gas-generating chamber under the action of the gas, and then activate the activation component.

[0027] Furthermore, the piercing component includes a piercing needle 371 and a sealing diaphragm 372. The piercing needle 371 can slide along the inner cavity of the gas-generating chamber 340. The sealing diaphragm 372 is disposed between the inlet chamber 350 and the main chamber 330. In use, the gas-generating agent in the gas-generating chamber is ignited to generate gas. The gas will drive the piercing needle to move towards the sealing diaphragm and pierce the sealing diaphragm, thereby realizing the connection between the inlet chamber, the main chamber and the outlet chamber, so as to facilitate the output of perfluorohexanone extinguishing agent.

[0028] It should be noted that the discharge chamber 360 is connected to the main chamber, and the extinguishing agent outlet 310 is located at the end of the discharge chamber 360 away from the main chamber 330. In this way, after the inlet chamber is connected to the main chamber through the puncture component, the main chamber can be connected to the discharge chamber, so that the perfluorohexanone extinguishing agent can be discharged through the extinguishing agent outlet.

[0029] Furthermore, the release pipe 40 is a siphon pipe with its bottom end placed inside the perfluorohexanone extinguishing agent and its top end connected to the starting component. In use, under the action of nitrogen pressure, when the extinguishing agent outlet at the end of the starting component is opened, nitrogen can drive the perfluorohexanone extinguishing agent inside the storage tank to be sprayed outward through the release pipe and the starting component to achieve the fire extinguishing effect.

[0030] Furthermore, the thermal initiator 50 is a thermally sensitive wire that can sense fire in the working environment, so as to transmit the fire signal to the activation component, thereby further controlling the thermal initiator to start the operation of the pressurized perfluorohexanone fire extinguishing device.

[0031] In use, the heat initiator 50 is placed at a fire hazard location. Once a fire occurs, if the flames reach the heat initiator 50 or the ambient temperature reaches a set temperature, such as 180°C, the heat initiator will detect the fire and transmit the fire signal to the activation component. This will activate the pressurized perfluorohexanone fire extinguishing device. The activation component will open the valve passage, and the nitrogen gas in the storage tank will drive the perfluorohexanone extinguishing agent to be discharged from the release pipe 40 to the outside of the storage tank 10. The perfluorohexanone extinguishing agent will then be sprayed at the location of the fire through the outlet of the activation component, thereby achieving fire extinguishing and cooling.

[0032] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
