[0002] With growing global attention to environmental protection and sustainable development, new energy vehicles (NEVs) have been widely promoted and adopted as a clean energy vehicle. Compared to traditional fuel vehicles, NEVs offer advantages such as low carbon emissions, zero tailpipe pollution, and energy efficiency, making them popular with consumers. However, the increasing number of NEVs has also brought new safety risks, one of which is fire accidents.

[0003] Currently, there are no better fire-fighting measures for fires in new energy vehicle power batteries. Many traditional fire-fighting equipment are not optimized for electric vehicles or specific battery modules, so they may be limited in effectiveness when dealing with electric vehicle fires. Traditional fire extinguishing agents such as dry powder, carbon dioxide, and heptafluoropropane, although they can extinguish battery fires, have poor cooling effects. High-temperature batteries will still heat adjacent batteries, easily causing thermal runaway of adjacent batteries, and ultimately causing thermal runaway to spread within the module.

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example, see Figures 1-4 A foaming fire extinguishing gun device includes a gun body and a foaming barrel 9. The gun body is composed of a gun base interface 1, a gun barrel body 2, a gun handle 3, a switch wrench 4, a medium and low power switch 5, a foaming stirring piece 6, a diverter baffle 7, and a mounting screw 8. The lower side wall of the gun barrel body 2 is fixedly connected to the gun handle 3. The gun barrel body 2 serves as the main channel for the circulation and foaming of the foam liquid. The gun handle 3 is for the operator to hold and control the direction and angle of the fire extinguishing gun. The switch wrench 4 is rotatably connected to the side wall of the gun barrel body 2. The switch wrench 4 controls the flow of the foam liquid. When the switch is turned, When closed, the foam liquid begins to enter the gun barrel 2 for foaming, the gun base interface 1 is fixedly connected to the rear section of the gun barrel 2, the diverter baffle 7 is fixed to the front section of the gun body by installing screws 8, and the foaming stirring piece 6 is rotatably connected to the inner wall of the gun barrel 2. In the initial state, the gun base interface 1 is connected to the foam fire extinguishing equipment, and a mounting plate 91 is installed on the upper end of the foaming barrel 9. Several elastic card plates 92 are installed in a ring shape on the inner side of the mounting plate 91. A card slot is provided at the bottom of the elastic card plate 92, and the foaming barrel 9 is movably plugged into the diverter baffle 7 through the card slot.

[0023] It should be noted that the foaming and stirring blade 6 has foaming performance. When the foam liquid passes through, the foaming of the foam liquid is promoted through the rotation and stirring effect, thereby improving the generation efficiency and quality of the foam.

[0024] Reference Figure 1-Figure 5 The diverter baffle 7 is fixed to the gun barrel 2 by installing screws 8. The diverter baffle 7 affects the flow path and distribution of the foam liquid, thereby adjusting the foam magnification and injection effect. The medium and low magnification switching switch 5 is connected to the gun barrel 2 by a threaded internal ball bearing. The outside of the gun barrel 2 corresponding to the medium and low magnification switching switch 5 has a ball limiting slide groove.

[0025] It should be noted that: turn the medium-low multiplication switch 5 clockwise, switch to the low-multiplication gun and then turn on the switch wrench 4. At this time, the equipment is in the low-multiplication foam opening state, and there is no need to install the foaming barrel 9 at this time; turn the medium-low multiplication switch 5 counterclockwise, switch to the medium-multiplication gun, plug in and install the foaming barrel 9 and then turn on the switch wrench 4. At this time, the equipment is in the medium-multiplication foam opening state. By rotating this switch, you can switch the working mode of the foaming gun, that is, low-multiplication foam or medium-multiplication foam mode.

[0026] In this embodiment, the foam generation process is as follows: when the foam fire extinguishing equipment supplies foam liquid to the gun barrel 2 through the gun base interface 1, the operator turns the switch wrench 4 to allow the foam liquid to flow into the gun barrel 2. When the foam liquid flows through the foaming stirring blade 6, a large number of tiny bubbles are generated due to the rotating stirring action of the stirring blade. These bubbles are stabilized and enlarged in the foam liquid to form foam. The setting of the diverter baffle 7 further optimizes the generation and distribution of foam, ensuring that the foam can be generated evenly and efficiently.

[0027] Medium and low-multiple switching mechanism: The operator selects the required foam ratio by rotating the medium and low-multiple switching switch 5 as needed. When the switch is rotated clockwise, the internal ball moves in the ball limit slide, adjusting the position of the diverter baffle 7, so that the equipment switches to the low-multiple foam mode. At this time, the flow path and foaming conditions of the foam liquid are adjusted to be suitable for the generation of low-multiple foam; when the switch is rotated counterclockwise, it is also through the interaction of the internal ball and the slide, with the cooperation of the foaming barrel 9, switching to the high-multiple foam mode, adjusting the foam ratio and injection characteristics.

[0028] When the power battery of a new energy vehicle catches fire, time is of the essence. The foaming fire extinguishing gun equipment can respond quickly, receive the foam liquid through the gun base interface 1, and start working immediately after the operator turns the switch wrench 4. The foaming stirring blade 6 rotates and stirs rapidly when the foam liquid flows through, and the air is evenly dispersed into the foam liquid, forming a large number of tiny and stable bubbles. These bubbles continue to grow and connect with each other in the foam liquid, and eventually a large amount of foam is generated. The generated foam is ejected at high pressure and quickly covers the surface of the fire source of the power battery pack of the new energy vehicle. The foam layer has good adhesion and extensibility, and can fit tightly on the surface of the battery pack to form a thick protective layer. This foam protective layer can not only effectively isolate the contact between oxygen and the fire source, but also reduce the temperature of the fire source surface through its thermal insulation performance, thereby slowing down the spread of the fire.

[0029] One of the main functions of the foam layer is to isolate oxygen. Since the foam is filled with a large number of tiny bubbles, these bubbles can prevent the oxygen in the air from directly contacting the fire source, thereby cutting off one of the three elements of combustion - the combustible material. At the same time, the foam layer also has good thermal insulation properties and can significantly reduce the temperature of the fire source surface. When the fire source temperature drops to a certain level, the combustion reaction will not be able to proceed and the fire will naturally be contained.

[0030] Low-expansion foam: Suitable for large-area fires or early-stage fires. Since low-expansion foam has a low foam multiple (i.e., the ratio of foam volume to foam liquid volume), it can quickly cover a large area and quickly suppress the spread of fire. In the early stages of a new energy vehicle power battery fire, the use of low-expansion foam can quickly control the fire and prevent it from further deteriorating.

[0031] Medium-expansion foam: Suitable for situations where higher fire extinguishing efficiency is required. Medium-expansion foam has a higher foam multiple and the foam layer is denser and thicker. When the fire is more intense or the fire spread path needs to be cut off quickly, the use of medium-expansion foam can more effectively isolate oxygen and reduce the temperature of the fire source, thereby quickly curbing the fire.

[0032] To sum up, the foaming fire extinguishing gun equipment can improve the foaming effect through the foaming stirring piece 6, the medium and low multiple switching switch 5, the foaming barrel 9 and the diversion baffle 7, so that the equipment can freely switch the medium and low multiple foam gun states, effectively improve the work efficiency, and when a fire occurs, it can improve high-efficiency foam and quickly realize the switching of low and medium multiple foams, quickly reduce the fire source temperature and isolate oxygen, effectively curb the spread of fire, and improve fire extinguishing efficiency and safety; you can also choose suitable fire extinguishing equipment for installation as needed, which improves the applicability and flexibility of the equipment.
