Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, specifically to a mobile perfluorohexanone fire extinguishing device for fire extinguishing. Background Technology

[0002] With the rapid development of modern industry, fire scenarios are becoming increasingly complex and varied, placing higher demands on firefighting technologies and equipment. Traditional extinguishing agents, such as dry powder, carbon dioxide, and water, have significant limitations in certain special locations and fire types. For example, in places with dense electronic equipment, such as computer rooms, museum exhibition halls for precious artifacts, and archives, dry powder extinguishing can cause secondary pollution and damage to precision equipment and artifacts; carbon dioxide extinguishing can cause asphyxiation in confined spaces; and water extinguishing can not only cause electric shock accidents due to conductivity but also cause serious damage to electrical equipment.

[0003] Perfluorohexanone (PFH) offers significant advantages as a novel fire extinguishing agent. It exhibits strong chemical stability, leaves no residue after extinguishing, is non-conductive, environmentally friendly, and boasts high fire extinguishing efficiency, rapidly suppressing flames and effectively extinguishing various types of fires, including Class A, B, and C fires, as well as electrical fires. However, currently, most PPH fire extinguishing devices are fixed installations in specific locations, lacking flexibility and failing to meet the mobile fire extinguishing needs of different areas. Especially in large-scale complexes, temporary structures, or scenarios with complex and ever-changing fire spread paths, it cannot respond quickly and be deployed promptly to critical fire-fighting locations.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] According to a first aspect of the present invention, a mobile perfluorohexanone fire extinguishing device for fire fighting includes a mobile vehicle body, a perfluorohexanone storage tank, a pressure delivery system, a spraying system, a control system, and a power supply device; the mobile vehicle body has a frame structure, wherein the perfluorohexanone storage tank, the pressure delivery system, and the power supply device are all installed inside the mobile vehicle body.

[0007] The perfluorohexanone storage tank is equipped with a liquid level monitoring device on its side wall, which is used to detect and display the storage amount in the perfluorohexanone storage tank.

[0008] The pressure delivery system is located below the perfluorohexanone storage tank. The injection system and the perfluorohexanone storage tank are connected through the pressure delivery system. The control system is electrically connected to the pressure delivery system and is used to control the injection state of the injection system.

[0009] The power supply device is vertically installed below the perfluorohexanone storage tank and spaced apart from the pressure transmission system. The power supply device is electrically connected to and supplies power to the control system and the liquid level monitoring device.

[0010] Furthermore, the mobile vehicle body is a rigid metal frame structure, and multiple sliding wheels are evenly provided at the bottom of the mobile vehicle body, with rubber tires installed on the sliding wheels.

[0011] Furthermore, the mobile vehicle body is equipped with a steering device and a braking device. The steering device is used to control the direction of movement of the sliding wheel, and the braking device is used to brake the sliding wheel.

[0012] Furthermore, the pressure delivery system includes a high-pressure pump and a pressure regulating device, which are spaced apart at the bottom of the mobile vehicle body. The inlet of the high-pressure pump is connected to the outlet of the perfluorohexanone storage tank, the outlet of the high-pressure pump is connected to the inlet of the pressure regulating device, the outlet of the pressure regulating device is connected to the inlet of the injection system, and the pressure regulating device is electrically connected to the control system.

[0013] Furthermore, the injection system is detachably mounted on the mobile vehicle body.

[0014] Furthermore, the spraying system includes a spray gun, a nozzle, and a bracket; the inlet of the spray gun is connected to the outlet of the pressure delivery system, the nozzle is installed at the outlet of the spray gun, the bracket is disposed between the spray gun and the nozzle, and the bracket is detachably connected to the mobile vehicle body.

[0015] Furthermore, the outer wall of the mobile vehicle body is provided with an operation panel, and the control system is installed on the operation panel.

[0016] Furthermore, the power supply device employs a rechargeable lithium battery pack.

[0017] This utility model has the following advantages:

[0018] This utility model features a mobile vehicle body, in which the perfluorohexanone storage tank, pressure delivery system, and power supply are all installed.

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figures 1 to 5As shown in the first aspect embodiment of this utility model, a mobile perfluorohexanone fire extinguishing device for fire fighting includes a mobile vehicle body 1, a perfluorohexanone storage tank 2, a pressure delivery system 3, a spraying system 4, a control system 5, and a power supply device 6. The mobile vehicle body 1 is welded from a rigid metal frame, and four sliding wheels with rubber tires 7 are installed at the four corners of the bottom.

The top of the tank also has an injection port and a pressure relief valve, while the bottom outlet is connected to the pressure transmission system 3 via a high-pressure hose.

[0033] The injection system 4 and the perfluorohexanone storage tank 2 are connected by a pressure transmission system 3. The control system 5 is electrically connected to the pressure transmission system 3 and is used to control the injection state of the injection system 4.

[0034] The power supply unit 6 is vertically installed below the perfluorohexanone storage tank 2 and is spaced apart from the pressure transmission system 3. The power supply unit 6 is electrically connected to and supplies power to the control system 5 and the liquid level monitoring device 8.

[0035] Optionally, the power supply unit 6 uses a rechargeable lithium battery pack 18. The lithium battery pack can continuously and stably output electrical energy, providing reliable power support for equipment such as the control system and liquid level monitoring device. At the same time, compared with traditional disposable batteries, the rechargeable lithium battery pack can be recycled multiple times, reducing the generation of battery waste and reducing environmental pollution.

[0036] It should be noted that the perfluorohexanone liquid stored in storage tank 2 is a new type of fire extinguishing agent. At room temperature, it is a clear, colorless, and odorless liquid with a boiling point of 48-49℃, low heat of vaporization, high vapor pressure, and easy vaporization. It has good chemical stability, leaves no residue after extinguishing, is non-conductive, environmentally friendly, and has high fire extinguishing efficiency, capable of rapidly suppressing flames and effectively extinguishing various types of fires, including Class A, B, and C fires, as well as electrical fires.

[0037] The pressure delivery system 3 includes a high-pressure pump 9 and a pressure regulating device 10. The high-pressure pump 9 and the pressure regulating device 10 are spaced apart at the bottom of the mobile vehicle body 1 and are fixed side by side within the bottom frame of the vehicle body 1. The pressure regulating device 10 is an electric proportional regulating valve. The inlet of the high-pressure pump 9 and the outlet of the perfluorohexanone storage tank 2 are connected by a stainless steel pipe. The outlet of the high-pressure pump 9 and the inlet of the pressure regulating device 10 are also connected by a stainless steel pipe. The outlet of the pressure regulating device 10 and the inlet of the injection system 4 are connected by a high-pressure hose. The length of the high-pressure hose between the pressure regulating device 10 and the injection system 4 can be adjusted according to actual needs. The pressure regulating device 10 and the control system 5 are electrically connected by a cable.

[0038] The spraying system 4 is detachably mounted on the mobile vehicle body 1. The mobile vehicle body 1 has a hook on the outside. The spraying system 4 includes a spray gun 11, a nozzle 12 and a bracket 13. The liquid inlet of the spray gun 11 is connected to the liquid outlet of the pressure delivery system 3. The nozzle 12 is installed at the liquid outlet of the spray gun 11. The bracket 13 is located between the spray gun 11 and the nozzle 12. The bracket 13 is U-shaped and is hung on the hook of the mobile vehicle body 1.

[0039] The outer wall of the mobile vehicle body 1 is provided with an operation panel 14, and the control system 5 is installed on the operation panel 14. The control system 5 includes a start button 15, a pressure control knob 16, and an injection mode selection switch 17. The start button 15 is used to control the start and stop of the pressure delivery system 3, the pressure control knob 16 is used to adjust the pressure of the pressure delivery system 3, and the injection mode selection switch 17 is used to switch the injection mode of the injection system 4.

[0040] How to use:

[0041] Push the portable perfluorohexanone fire extinguishing device to a safe location close to the fire scene. Check the liquid level monitoring device on the side wall of the perfluorohexanone storage tank to confirm that the perfluorohexanone storage level in the tank is sufficient, and at the same time ensure that the power supply is within the normal operating range.

[0042] Operate the control panel on the outer wall of the mobile vehicle and press the start button on the control system to activate the pressure delivery system. Adjust the pressure of the pressure delivery system according to the fire situation using the pressure control knob on the control panel. Simultaneously, toggle the spray mode selection switch to switch the spray system to the appropriate mode. At this point, perfluorohexanone is pressurized and delivered from the storage tank to the spray system via the pressure delivery system. Firefighters then use spray guns to aim at the base of the fire and extinguish it.

[0043] After the fire is extinguished, press the start button again to shut down the pressure delivery system. If the amount of perfluorohexanone in the storage tank (2) is insufficient, replenish the perfluorohexanone in time; if the power supply is low, charge it.

[0044] Working principle:

[0045] The power supply unit uses a rechargeable lithium battery pack to power the entire fire extinguishing system. When the start button is pressed, the power supply unit supplies power to the control system, which then sends a start signal to the pressure delivery system. The high-pressure pump in the pressure delivery system starts, extracting and pressurizing the perfluorohexanone from the storage tank. The pressurized perfluorohexanone enters the pressure regulating device, which precisely adjusts the pressure of the perfluorohexanone according to the pressure parameters set by the control system, ensuring a stable pressure of perfluorohexanone is delivered to the spray system.

[0046] The level monitoring device is installed on the side wall of the perfluorohexanone storage tank. Its working principle is based on a certain level detection technology (such as ultrasonic level detection, capacitive level detection, etc., which are existing technologies and will not be described in detail here). The device detects the level of perfluorohexanone in the storage tank in real time and converts the level information into an electrical signal, which is then transmitted to the control system. The control system displays the level information intuitively to the operator through a display interface, allowing for easy monitoring of the amount of perfluorohexanone stored in the tank.

[0047] The control system controls the pressure and start / stop of the pressure delivery system via electrical connections, thereby indirectly controlling the spraying state of the spraying system. When the operator adjusts the pressure control knob, the control system adjusts the control command to the pressure regulating device according to the electrical signal corresponding to the knob position, changing the perfluorohexanone pressure output to the spraying system and thus controlling the spraying force. The spraying mode selection switch changes the output signal of the control system, allowing the spraying system to switch between different operating modes, such as columnar spray mode and mist spray mode, to adapt to the fire extinguishing needs of different types of fires.

[0048] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0049] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
