[0001] The invention relates to the field of fire safety, in particular to a long-distance perfluorohexanone fire extinguishing device and a use method thereof. Background Art

[0002] As a new type of clean and environmentally friendly fire extinguishing agent, perfluorohexanone is highly efficient, environmentally friendly and safe. It is a colorless, odorless, transparent liquid at room temperature. It has good electrical insulation and non-conductivity, and is particularly suitable for electrical fires.

[0003] However, traditional liquid perfluorohexanone fire extinguishing devices have certain limitations in spraying distance. During long-distance spraying, due to factors such as ambient temperature and friction during the spraying process, perfluorohexanone may vaporize prematurely, resulting in limited spraying distance and unable to meet the remote fire extinguishing needs in some special occasions. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is that the existing perfluorohexanone fire extinguishing device has a short fire extinguishing distance.

[0012] In a preferred embodiment of the long-distance perfluorohexanone fire extinguishing device of the present invention: the controller is connected to the peristaltic pump via a wired interface, and the controller receives a signal transmitted by the smoke sensor, and then controls the peristaltic pump to start.

[0013] In a preferred embodiment of the long-distance perfluorohexanone fire extinguishing device of the present invention: the heating module of the heating module is preferably a heating wire;

[0016] In a preferred embodiment of the long-distance perfluorohexanone fire extinguishing device of the present invention: a temperature measuring element is installed on one side of the electric valve, and the temperature measuring element can obtain the real-time gas temperature value at the outlet of the fire protection pipeline;

[0017] The controller is connected to the temperature measuring element and the temperature controller of the heating module, and then controls the heating temperature of the heating module through the gas temperature value.

[0018] In a preferred embodiment of the long-distance perfluorohexanone fire extinguishing device of the present invention: a digital pressure sensor is installed inside the high-pressure gas storage tank, and the digital pressure sensor can detect the internal pressure of the high-pressure gas storage tank;

[0019] The pressure value of the digital pressure sensor can provide a reference for controlling the speed of the peristaltic pump.

[0020] The beneficial effect of the present invention is that when the smoke sensor in the fire detector senses smoke, it will promptly feedback to the controller, and the controller automatically responds to make commands to the heating module and the peristaltic pump, the heating module works, the heating wire is energized, the resistor generates heat to heat the high-pressure gas storage tank, the peristaltic pump transports perfluorohexanone to the high-pressure gas storage tank, and the heat is conducted into the high-pressure gas storage tank to gasify the perfluorohexanone.

[0031] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0032] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0033] Reference Figure 1 and 2The present embodiment provides a long-distance perfluorohexanone fire extinguishing device, including a high-pressure gas storage tank 1, a fire-fighting pipeline 2, a high-pressure nozzle 3, an electric valve 5, a fixed sleeve 7 and a heating module 8. The high-pressure gas storage tank 1 is connected to the fire-fighting pipeline 2, a high-pressure nozzle 3 is installed at the end of the fire-fighting pipeline 2, and an electric valve 5 is installed between the fire-fighting pipeline 2 and the high-pressure nozzle 3. The electric valve 5 can ensure that a certain pressure value can be reached inside the high-pressure gas storage tank 1. The fixed sleeve 7 is coated on the side wall of the high-pressure gas storage tank 1, and a heating module 8 is arranged between the fixed sleeve 7 and the high-pressure gas storage tank 1.

[0034] In this embodiment, the perfluorohexanone inside the high-pressure gas storage tank 1 is heated by the heating module 8, so that the perfluorohexanone is completely vaporized and a certain pressure is formed inside the high-pressure gas storage tank 1; when the predetermined pressure is reached, it will be ejected from the inside of the high-pressure nozzle. Under the action of high pressure, the completely vaporized perfluorohexanone can be ejected to a longer distance. After the perfluorohexanone is vaporized, a layer of protective steam cloud will be formed to cover the surface of the burning object, preventing oxygen in the air from contacting the fuel, thereby cutting off the oxygen supply, one of the three elements of combustion, to achieve the effect of suffocation and extinguishing the fire, thereby achieving the purpose of large-scale fire extinguishing.

[0035] The interior of the high-pressure gas storage tank 1 is connected to the fire-fighting pipeline 2. When the perfluorohexanone in the high-pressure gas storage tank 1 is completely gasified, it can flow along the fire-fighting pipeline 2 to the position of the high-pressure nozzle 3 and spray outward.

[0036] The electric valve 5 is arranged between the fire-fighting pipeline 2 and the high-pressure nozzle 3; the electric valve 5 can ensure that during the increase of the pressure inside the high-pressure gas storage tank 1, the perfluorohexanone gas will not flow along the fire-fighting pipeline 2 to the high-pressure nozzle 3. As the heating module 8 continues to heat, the pressure inside the high-pressure gas storage tank 1 can gradually increase, thereby ensuring that the vaporized perfluorohexanone can move to a farther distance when sprayed out.

[0037] The fixing sleeve 7 mainly plays the role of installation and fixing, so that the device can be installed in a suitable position inside the electrical place; the inner side of the fixing sleeve 7 is provided with heat insulation cotton, so as to further block the diffusion of heat and ensure the high efficiency of the heating process.

[0038] The heating module 8 is disposed outside the high-pressure gas storage tank 1. The high-pressure gas storage tank 1 can be heated by the heating module 8, so that the perfluorohexanone inside the high-pressure gas storage tank 1 is completely gasified, so as to better achieve the effect of isolating oxygen.

[0039] The nozzle of the high-pressure nozzle 3 is conical in shape to reduce the resistance of the airflow in the nozzle and increase the injection speed; the cross-section of the inner hole of the nozzle is contracted to convert the pressure energy of the high-pressure gas into kinetic energy, thereby increasing the injection speed and injection distance; thus, it can be used in situations with longer injection distances.

[0040] The electric valve 5 is preferably a solenoid valve, which has an extremely short response time and can react immediately when a fire occurs; when the system detects a fire signal, the solenoid valve can open quickly, allowing the fire extinguishing agent to be quickly released to the fire scene, thereby effectively controlling the fire.

[0041] This fast response feature is crucial to improving fire extinguishing efficiency; the solenoid valve achieves precise control of the fire extinguishing agent through the principle of electromagnetic induction; when the fire extinguishing agent needs to be released, the solenoid valve can be accurately opened; when it is not needed, it remains closed; this precise control capability avoids waste of fire extinguishing agent and accidental injuries, ensuring the effective use of fire extinguishing agent.

[0042] The heating module 8 can completely gasify the perfluorohexanone in the high-pressure gas storage tank 1, thereby enabling the gasified perfluorohexanone fire extinguishing agent to flow along the fire-fighting pipeline 2 to the high-pressure nozzle 3 and be sprayed out over a long distance.

[0043] When in use, the heating module 8 heats the perfluorohexanone inside the high-pressure gas tank 1. During the heating process, the electric valve 5 between the fire-fighting pipeline 2 and the high-pressure nozzle 3 is in a closed state. With continuous heating, the perfluorohexanone inside the high-pressure gas tank 1 is completely vaporized and the internal pressure of the high-pressure gas tank 1 increases. When the internal pressure of the high-pressure gas tank 1 reaches a certain value, the electric valve 5 is opened, and then the high-pressure vaporized perfluorohexanone is sprayed along the high-pressure nozzle 3 to a farther distance and is located on the surface of the burning object to form a steam cloud covering its surface, so as to achieve the purpose of isolating oxygen and preventing it from burning.

[0044] As an optional embodiment, a smoke sensor 4 is installed on the outer wall of the high-pressure nozzle 3, and a controller 9 is installed on the outer side of the fixing sleeve 7; the controller 9 is connected to the smoke sensor 4 through a wired interface, thereby ensuring real-time and reliable signal transmission.

[0045] In this embodiment, the signal transmitted to the controller 9 by the smoke sensor 4 enables the controller 9 to issue a corresponding control command, so that a quick response can be made when a fire occurs.

[0046] The smoke sensor 4 is installed on the outside of the high-pressure nozzle 3 so as to detect smoke signals when a fire occurs. The smoke sensor 4 is equipped with a standard communication interface, which is connected to a corresponding port on the controller 9 via a shielded twisted pair cable.

[0047] In one embodiment provided in the present application, a liquid storage tank 10 and a peristaltic pump 11 are included, and the liquid storage tank 10 and the peristaltic pump 11 are connected through a delivery pipe; the peristaltic pump 11 is connected to the high-pressure gas storage tank 1 through a delivery pipe, and the liquid storage tank 10 stores perfluorohexanone fire extinguishing agent, and the perfluorohexanone fire extinguishing agent inside is delivered to the inside of the high-pressure gas storage tank 1 through the peristaltic pump 11.

[0048] In this embodiment, the perfluorohexanone fire extinguishing agent in the liquid storage tank 10 can be transported to the high-pressure gas storage tank 1 through the peristaltic pump 11; thereby multiple spraying can be achieved to achieve a better fire extinguishing effect and reduce the waste of resources to a certain extent.

[0049] The pumping end of the peristaltic pump 11 is connected to the liquid storage tank 10 through a pipeline, and the output end of the peristaltic pump 11 is connected to the high-pressure gas storage tank 1 through a pipeline; the liquid storage tank 10 stores liquid perfluorohexanone fire extinguishing agent.

[0050] As an optional embodiment, the controller 9 is connected to the peristaltic pump 11 via a wired interface, and the controller 9 receives the signal transmitted by the smoke sensor 4, and then controls the peristaltic pump 11 to start.

[0051] In this embodiment, the peristaltic pump 11 can be controlled to start by the controller 9. When the controller 9 receives the smoke signal, it can respond quickly and control the peristaltic pump 11 to start, so that the peristaltic pump 11 transports the perfluorohexanone in the liquid storage tank 10 to the high-pressure gas storage tank 1. Through this setting, the device can respond quickly when a fire occurs to gain more precious time.

[0052] As an optional embodiment, the heating module including the heating module 8 is preferably a heating wire; the heating wire is evenly wound around the outside of the high-pressure gas storage tank 1 .

[0053] In this embodiment, the heating wire is wound around the outside of the high-pressure gas storage tank 1, so that the heating process can be carried out efficiently, thereby ensuring that the time for the perfluorohexanone inside the high-pressure gas storage tank 1 to be completely gasified is shortened.

[0054] Furthermore, the high-pressure gas storage tank 1 is a cylindrical cavity structure, and the inner wall is made of copper with good thermal conductivity.

[0055] Specifically, the heating wire enables heat to be directly and evenly transferred to the object it contacts; the heating wire is wound around the outer wall of the high-pressure gas storage tank 1 to ensure effective heat transfer. Such a layout not only improves the heat conduction efficiency, but also makes the heating process more uniform, avoiding the problem of local overheating or insufficient temperature.

[0056] The high-pressure gas storage tank 1 is designed as a cylindrical cavity structure, which is not only convenient for winding the heating wire, but also provides sufficient space for accommodating and transferring heat.

[0057] The high thermal conductivity of copper enables heat to be quickly and evenly distributed inside the high-pressure gas storage tank 1, thereby improving the thermal response speed and efficiency of the entire heating module.

[0058] In an embodiment provided in the present application, the controller 9 is connected to the heating module 8 via a wired interface, and the controller 9 receives a signal transmitted by the smoke sensor 4, and then controls the heating module 8 to start.

[0059] In this embodiment, the heating module 8 is started under the control of the controller 9. When the smoke sensor 4 transmits a signal to the controller 9, the controller 9 will respond quickly and control the heating module 8 to start, thereby efficiently completing the heating of perfluorohexanone.

[0060] When the controller 9 receives the signal transmitted by the smoke sensor 4, the controller 9 controls the peristaltic pump 11 and the heating module 8 to start at the same time, completing the process of transporting perfluorohexanone to the inside of the high-pressure gas storage tank 1 and gasifying it; the whole process is efficient and stable, and remote fire extinguishing can be achieved.

[0061] As an optional embodiment, a temperature measuring element 6 is installed on one side of the electric valve 5, and the temperature measuring element 6 can obtain the real-time gas temperature value at the outlet of the fire protection pipeline 2; the controller 9 is connected to the temperature measuring element 6 and the thermostat control of the heating module 8, and then controls the heating temperature of the heating module 8 through the gas temperature value.

[0062] In this embodiment, the temperature measuring element 6 is installed at the electric valve 5 to obtain the real-time gas temperature value at the outlet of the fire protection pipeline 2; the controller 4 is connected to the temperature measuring element 77 and the thermostat control of the heating wire, and is controlled by the controller 4 to control the heating temperature of the heating wire according to the gas temperature value.

[0063] As an optional embodiment, a digital pressure sensor 12 is installed inside the high-pressure gas storage tank 1, and the digital pressure sensor 12 can detect the internal pressure of the high-pressure gas storage tank 1; the pressure value of the digital pressure sensor 12 can provide a reference for controlling the rotation speed of the peristaltic pump 11.

[0064] In this example, the digital pressure sensor 12 can detect the pressure inside the high-pressure gas storage tank 1. When the pressure inside the high-pressure gas storage tank 1 reaches a predetermined value, the digital pressure sensor 12 will feedback a signal to the controller 4. The controller smoke sensor 4 controls the electric valve 5 to open, so that the completely vaporized perfluorohexanone fire extinguishing agent can be sprayed out; through the detection of the digital pressure sensor 12, the vaporized perfluorohexanone fire extinguishing agent is emitted under high pressure, which can achieve long-distance spraying and better fire extinguishing effect.

[0065] Furthermore, the digital pressure sensor 12 displays the pressure value inside the high-pressure gas storage tank 1, which can be used as a reference for controlling the rotation speed of the peristaltic pump 11, thereby controlling the content of the generated gaseous perfluorohexanone to prevent the pressure from being too high to pose a safety hazard or the pressure from being too low to be sufficient for long-distance spraying to achieve fire extinguishing.

[0066] Furthermore, the temperature of the heating module 8 can be controlled by the value of the digital pressure sensor 12 to control the pressure of the gas.

[0067] Reference Figure 1 to Figure 3 The present embodiment provides a method for using a long-distance perfluorohexanone fire extinguishing device, including: S1: detecting a signal through a smoke sensor and feeding it back to a controller; S2: the controller controls the peristaltic pump and the heating module to start; S3: the heating module opens the electric valve after completely vaporizing the perfluorohexanone; S4: the completely vaporized perfluorohexanone is sprayed to a long distance along a high-pressure nozzle through a fire-fighting pipe.

[0068] In this embodiment, the above-mentioned operation method can be used to quickly gasify perfluorohexanone and spray out high-pressure perfluorohexanone gas. The high-pressure perfluorohexanone can achieve long-distance coverage during the spraying process, thereby expanding the range of fire extinguishing.

[0069] When the smoke sensor detects a fire signal and the controller determines that a fire has occurred, the controller will immediately trigger the heating module and the peristaltic pump to start; the heating module works, the heating wire is energized, the resistor generates heat to heat the high-pressure gas tank in the carrier unit, and the peristaltic pump transports perfluorohexanone to the high-pressure gas tank, and the heat conduction enters the high-pressure gas tank to gasify the perfluorohexanone. When the digital pressure sensor detects that the gasification of the fire extinguishing agent reaches a certain pressure, it will promptly feedback to the controller, and the controller automatically responds to the control of the electric valve; the high-pressure gas tank is connected to the fire-fighting pipeline. When the electric valve is opened, due to the effect of atmospheric pressure, the gasified perfluorohexanone fire extinguishing agent flows along a specific fire-fighting pipeline to the high-pressure nozzle; at the nozzle, the fire extinguishing agent is sprayed out in a suitable jet form according to the internal flow guide structure of the nozzle and the pre-set spray angle and other parameters, accurately covering the fire source area, and quickly suppressing and extinguishing the fire through the fire extinguishing effect of the perfluorohexanone fire extinguishing agent;

[0070] As an optional embodiment, the electric valve, the heating module and the peristaltic pump can be independently controlled by a remote controller.

[0071] In this embodiment, if the fire does not generate smoke that prompts the smoke sensor to respond in time, but the management personnel discover the fire in time, they do not need to run to the front of the equipment, but can also use the portable remote controller to remotely control the device to spray gas fire extinguishing agent to extinguish the fire, forming a double protection.

[0072] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
