[0042] In the description of the present invention, it should be understood that the terms indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention; in the description of the present invention, the meanings of "a plurality" and "several" are at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] Embodiment 1

[0044] Please refer to Figures 1 to 4 As shown, the present invention is a mobile shed fire extinguishing device, including a mobile vehicle frame 1 with universal wheels 14, a flip-fold shed mechanism and a fire extinguishing mechanism; a plurality of universal wheels 14 are provided on the bottom end surface of the mobile vehicle frame 1, and a flip-fold shed mechanism and a fire extinguishing mechanism are designed on the mobile vehicle frame 1. When a vehicle catches fire, the operator can move the entire mobile vehicle frame 1 to the fire location, flip and unfold the flip-fold shed mechanism to cover the burning vehicle, so as to use the fire extinguishing mechanism for targeted and rapid fire extinguishing treatment, and can be quickly started in the initial stage of the fire to effectively control the spread of the fire.

[0045] The mobile shed fire extinguishing device of the present application has flexible mobility and can be applicable to different scenarios, such as underground parking lots, charging stations, road rescue, etc. Moreover, compared with the traditional fire extinguishing system, the manufacturing cost and operation cost are significantly reduced.

[0046] During the design process of the flipping and folding carport mechanism in this application, the flipping and folding carport mechanism can be flipped open or folded and retracted on the mobile vehicle frame 1. The flipping and folding carport mechanism includes multiple folding skeletons 2 in the shape of U structures. The tail end of the folding skeleton 2 is rotatably connected to one end of the extended leg rod 4 through a positioning block 3, and the other end of the extended leg rod 4 is fixedly connected to the mobile vehicle frame 1. When the flipping and folding carport mechanism is flipped open, the multiple folding skeletons 2 in the shape of U structures can rotate synchronously along the positioning block 3 to open, forming an arc-shaped flipped-open cover to facilitate fully covering the burning vehicle for subsequent fire extinguishing treatment. The fire ignition position can be fully covered for fire extinguishing. Among them, the flipping angle range of the flipping and folding carport mechanism is 0-180°. When the flipping and folding carport mechanism is folded and retracted, the multiple folding skeletons 2 in the shape of U structures can rotate synchronously along the positioning block 3 to come closer, thus lifting the coverage of the burning vehicle to facilitate the next use for fire extinguishing and movement.

[0047] In this specific embodiment, a flame-retardant cloth 16 is arranged on the flipping and folding carport mechanism. The multiple folding skeletons 2 are connected through the flame-retardant cloth 16. The arranged flame-retardant cloth 16 enables the multiple folding skeletons 2 in the shape of U structures to be flipped open or folded and retracted synchronously. The arranged flame-retardant cloth 16 facilitates forming a sealed space when covering the burning vehicle, preventing the spread of fire smoke and accelerating vehicle fire extinguishing. Among them, the flame-retardant cloth 16 can be a fireproof silicone cloth, which has high temperature resistance, flame retardancy, insulation, anti-corrosion, and anti-aging characteristics, helping to extend the service life of the mobile carport fire extinguishing device in this application.

[0048] In this specific embodiment, the innermost folding skeleton 2 of the flipping and folding carport mechanism is fixedly connected to the extended leg rod 4 through a diagonal brace 5; the diagonal brace 5 limits the inclination angle of the innermost folding skeleton 2 of the flipping and folding carport mechanism to limit the folded and retracted state of the flipping and folding carport mechanism to avoid interference with the fire extinguishing mechanism and the driving mechanism.

[0049] In this application, a driving mechanism is designed to be drivingly connected to the flipping and folding carport mechanism. The flipping and folding carport mechanism is controlled to be flipped open or folded and retracted through the driving mechanism. The driving mechanism includes a winch 10 fixedly installed on the mobile vehicle frame 1. One end of a towing rope 11 is wound around the wire winding wheel of the winch 10, and the other end of the towing rope 11 is connected to the outermost folding skeleton 2 of the flipping and folding carport mechanism. The towing rope 11 is arranged on both sides of the flipping and folding carport mechanism through a guide pulley 12 and a guide pulley 13. The guide pulley 12 is arranged on both sides of the mobile vehicle frame 1, and the guide pulley 13 is fixedly connected to the folding skeleton 2.

[0050] When the multiple U-shaped folding skeletons 2 in the flipping and folding shed mechanism are flipped and opened or folded and retracted, a driving mechanism can be used for assistance. The driving mechanism opens the winch 10 to relax the traction ropes 11 redirected to both sides of the flipping and folding shed mechanism, so that the multiple U-shaped folding skeletons 2 are flipped and opened synchronously and stably; when folding and retracting is required, the winch 10 winds up the traction ropes 11 to make the multiple U-shaped folding skeletons 2 fold and retract synchronously and stably, which is convenient to operate and saves time and effort.

[0051] During the design process of the driving mechanism of this application, the winch 10 is electrically connected to the electric control box 15 on the back of the mobile vehicle frame 1. The electric control box 15 can be a PLC control cabinet. Through the PLC control cabinet, the forward and reverse rotation actions of the winch 10 can be intelligently and automatically controlled to realize the automatic control of the flipping and opening or folding and retracting of the flipping and folding shed mechanism.

[0052] During the design process of the fire extinguishing mechanism in this application, the hose 6 included in the fire extinguishing mechanism is arranged on both sides of the flipping and folding shed mechanism and can be flipped and opened or folded and retracted following the flipping and folding shed mechanism. A plurality of nozzles 7 are provided on the hose 6; each folding skeleton 2 is snap-connected to the hose 6 through a positioning pipe clamp 8. The input end of the hose 6 is connected to the fire extinguishing agent storage tank 9 on the mobile vehicle frame 1, and the control valve on the fire extinguishing agent storage tank 9 is electrically connected to the electric control box 15 on the back of the mobile vehicle frame 1.

[0053] This application can also use a PLC control cabinet to intelligently and automatically control the delivery or closing of the fire extinguishing agent. When the control valve is opened, the fire extinguishing agent storage tank 9 can conduct high-pressure delivery of the fire extinguishing agent into the opened hose 6, so as to facilitate fire extinguishing through a plurality of nozzles 7. The spraying angle of the nozzles 7 can be obliquely downward to completely cover the burning vehicle for fire extinguishing. Among them, the fire extinguishing agent can be perfluoromethylcyclohexanone fire extinguishing agent, and the fire extinguishing agent storage tank 9 is a special pressure vessel, and the pressure of the pressure vessel can be 2.5 MPa to ensure the liquid spraying efficiency, so that the pressure vessel of the fire extinguishing agent storage tank 9 can conduct high-pressure delivery of the fire extinguishing agent. The perfluoromethylcyclohexanone fire extinguishing agent has the following advantages during use:

[0054] 1. Heat transfer inhibition: The perfluoromethylcyclohexanone fire extinguishing agent can quickly vaporize and absorb a large amount of heat during the fire extinguishing process, thereby reducing the temperature on the surface of the combustible, achieving the purpose of fire extinguishing. In addition, the perfluoromethylcyclohexanone molecule contains fluorine elements and has excellent stability, making it not easily decomposed at high temperatures, avoiding the further activation of free radicals generated by the combustion of combustibles, and thus effectively inhibiting the transmission of combustion.

[0055] 2. Reduction of oxygen concentration: During the fire extinguishing process, perfluorohexanone fire extinguishing agent can rapidly reduce the oxygen concentration, thereby destroying the combustion conditions and achieving the purpose of fire extinguishing. The fluorine element in the perfluorohexanone molecule has extremely strong oxidizing properties and can quickly react with oxygen to generate inert gases, thus reducing the oxygen concentration and preventing combustion from continuing.

[0056] 3. Chemical inhibition: Perfluorohexanone fire extinguishing agent can quickly react with free radicals on the surface of the combustible, thereby disrupting the progress of the combustion chain reaction. The carbon atoms in the perfluorohexanone molecule have relatively high reactivity and can quickly combine with free radicals on the surface of the combustible to form stable compounds, thus blocking the reaction process of the combustion chain.

[0057] 4. Isolation of air: During the fire extinguishing process, perfluorohexanone fire extinguishing agent can quickly form a dense covering layer to isolate the contact between air and the surface of the combustible, thereby effectively suppressing the progress of combustion. In addition, the perfluorohexanone molecule has good stability and is not easily decomposed, thus ensuring its inhibitory effect on combustion over a long period of time.

[0058] It should be understood that the fire extinguishing agent storage tank 9 can be set into 2 groups according to actual needs, and then can be started twice for jet fire extinguishing use. The method of starting twice separately for fire extinguishing can prevent re-ignition or ignition of adjacent vehicles.

[0059] It should be understood that a smoke sensor and an audible and visual alarm can be integrated on the electric control box 15. The vehicle fire monitoring signal is sent to the PLC control cabinet through the smoke sensor, so that the mobile carport fire extinguishing device can be integrally moved to the fire location, quickly used for fire extinguishing, and at the same time, an audible and visual alarm is issued for warning.

[0060] Embodiment 2

[0061] As Figure 5 shown, a method for using a mobile carport fire extinguishing device includes the following steps:

[0062] Step S10: Push the mobile carport fire extinguishing device to the vehicle fire location. The mobile carport fire extinguishing device is designed and composed of a mobile vehicle frame 1 with universal wheels 14, a flipping and folding carport mechanism, a fire extinguishing mechanism, and a driving mechanism; a plurality of universal wheels 14 are provided on the bottom end surface of the mobile vehicle frame 1. When a vehicle catches fire, the operator can move the entire mobile vehicle frame 1 to the fire location, which has mobility flexibility and can be applied to different scenarios, such as underground parking lots, charging stations, road rescue, etc. Moreover, compared with traditional fire extinguishing systems, the manufacturing cost and operating cost are significantly reduced.

[0063] Step S20: Control the flipping and folding carport mechanism to open through the driving mechanism. While opening, move the carport fire extinguishing device to emit an acoustic and optical alarm through the acoustic and optical alarm device, prompting the evacuation of the crowd. In this application, it is designed that the driving mechanism is drivingly connected to the flipping and folding carport mechanism. The driving mechanism rotates the winch 10 forward to relax the traction ropes 11 redirected to both sides of the flipping and folding carport mechanism, and the flame-retardant cloth 16 arranged on the flipping and folding carport mechanism enables the synchronous flipping and opening of the folding skeletons 2 in the shape of multiple U-shaped structures. The arranged flame-retardant cloth 16 is convenient for forming a sealed space when covering the burning vehicle, avoiding the spread of fire smoke, and at the same time can accelerate the extinguishing of the vehicle fire. Among them, the flame-retardant cloth 16 can be a fireproof silica cloth, which has the characteristics of high temperature resistance, flame retardancy, insulation, anti-corrosion, and anti-aging, helping to improve the service life of the mobile carport fire extinguishing device in this application.

[0064] Step S30: Control the nozzle 7 on the hose 6 to conduct full-coverage fire extinguishing through the fire extinguishing mechanism. The hose 6 included in the fire extinguishing mechanism is arranged on both sides of the flipping and folding carport mechanism and can be flipped and opened following the flipping and folding carport mechanism. Multiple nozzles 7 are provided on the hose 6. When the control valve is opened, the fire extinguishing agent storage tank 9 can conduct high-pressure delivery of the fire extinguishing agent into the opened hose 6 to facilitate fire extinguishing treatment through the multiple nozzles 7.

[0065] Step S40: After the fire extinguishing is completed, fold and retract the flipping and folding carport mechanism. In this application, the driving mechanism rotates the winch 10 in the reverse direction to tighten the traction ropes 11 redirected to both sides of the flipping and folding carport mechanism, and the flame-retardant cloth 16 arranged on the flipping and folding carport mechanism enables the synchronous folding and retraction of the folding skeletons 2 in the shape of multiple U-shaped structures, which is convenient to operate, time-saving and labor-saving, and is convenient for the next fire extinguishing use.

[0066] The fire extinguishing method of this application solves the problems of low fire extinguishing efficiency, poor flexibility, and high cost in the prior art, and realizes rapid coverage of the fire source, accurate fire extinguishing, and prevention of re-ignition.

[0067] Embodiment 3

[0068] As Figure 6 shown, a mobile carport fire extinguishing system includes a control module and a driving mechanism, a fire extinguishing mechanism, and an acoustic and optical alarm module electrically connected to the control module. Among them, the driving mechanism is used to control the flipping and opening or folding and retraction of the flipping and folding carport mechanism; the fire extinguishing mechanism is used to control the nozzle 7 on the hose 6 to conduct full-coverage fire extinguishing; the acoustic and optical alarm module is used to emit an acoustic and optical alarm; the control module is used to run the instruction generation program of the driving mechanism, the fire extinguishing mechanism, and the acoustic and optical alarm module. When the instruction generation program is executed by the control module, it realizes the steps of the usage method of the mobile carport fire extinguishing device as described above.

[0069] During the use of the fire extinguishing system of the present application, the control module can adopt a PLC control cabinet, which can control the forward and reverse rotation of the winch of the driving mechanism to generate instructions for the flipping and unfolding or folding and retracting of the flipping and folding shed mechanism. The fire extinguishing mechanism can be flipped and unfolded or folded and retracted following the flipping and folding shed mechanism, so as to facilitate the operation of the fire extinguishing mechanism for full coverage fire extinguishing. The intelligent integration operation is convenient, ensuring a rapid fire extinguishing effect.

[0070] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
