Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishing, and in particular to a compressed air foam fire extinguishing device for new energy vehicles. Background Art

[0002] The compressed air foam fire extinguishing device compresses air and injects it into the foam mixture to form a very stable foam before it is sprayed out. The foam has higher viscosity and adhesion, can more effectively cover the fire source, and prevent oxygen from reaching the surface of the burning object. At the same time, it can absorb a large amount of heat, thereby improving the fire extinguishing efficiency. For example, when the lithium battery of a new energy vehicle is in thermal runaway, it will cause violent combustion and potential explosion risks. Traditional water fire extinguishing methods may cause water to flow into the battery pack, which may cause the battery to short circuit or fail. The compressed air foam fire extinguishing device can form a layer of stable foam to cover the burning object, isolating oxygen and reducing heat transfer. Therefore, for new energy vehicles, the compressed air foam fire extinguishing device is a more suitable fire extinguishing device.

[0003] In the existing patent CN217286961U, a fully integrated compressed air foam fire extinguishing device is disclosed, including a base and an electric control component integrated and installed on the base, a gasoline engine component, a fire pump component, a foam pump component and a screw air compressor delivery component; wherein the gasoline engine component drives the fire pump component to operate so as to deliver water from a fire hydrant to a mixing pipe; the gasoline engine component drives the foam pump component to operate so as to enable the foam pump component to deliver the foam liquid in the foam liquid tank to the mixing pipe, so that the foam liquid in the mixing pipe is mixed with water in proportion to form a mixed liquid; the proportioning mixer is connected to the mixing pipe so that the mixed liquid in the mixing pipe enters the proportioning mixer; the gasoline engine component drives the screw air compressor delivery component to operate so that the compressed air is delivered to the proportioning mixer after being cooled by the heat exchanger component. The utility model fills the gap in the fire extinguishing level of common compressed air foam systems and is flexible to use.

[0004] In the above structure, the function of compressed air foam fire extinguishing can be realized, but when preparing the mixed liquid, the ratio of foam liquid to water is difficult to flexibly adjust, resulting in the device being unable to automatically proportion different combustibles, and it is difficult to accurately control the device, making it difficult to match the device and the combustibles, reducing the device's adaptability to various combustibles, reducing the device's adaptability, reducing the stability of the foam, affecting the foam's covering ability and cooling effect, thereby affecting the fire extinguishing effect and reducing the fire extinguishing efficiency.

[0046] like Figure 5 and Fig.10 As shown, a compressed air foam fire extinguishing device for a new energy vehicle of the present invention, the transmission assembly 11 includes two mounting plates 1101 arranged on the mixing tube 506, the mounting plate 1101 is connected with a shaft 1102 with a bearing, the end of the shaft 1102 is fixedly sleeved with a transmission gear 1103, the output end of the electric push rod 901 is provided with a connecting block 1104, and the connecting block 1104 is provided with a plurality of spur racks 1105 meshing with the transmission gear 1103, and the plurality of spur racks 1105 are distributed at intervals. In this solution, three spur racks 1105 are provided.

[0047] like Figure 5 , Figure 6 and Fig.10As shown, a compressed air foam fire extinguishing device for a new energy vehicle of the present invention, the limiting mechanism 10 includes a guide plate 1001 arranged on a mounting plate 1101, a straight rack 1002 is slidably arranged on the guide plate 1001, a transmission gear 1003 meshing with the straight rack 1002 is fixedly sleeved on the shaft 1102, a connecting rod 1004 is arranged on the straight rack 1002, and a clamping gear 1005 is connected to the end of the rotating rod 701, and a clamping tooth 1006 meshing with the clamping gear 1005 is arranged on the connecting rod 1004. When the clamping tooth 1006 meshes with the clamping gear 1005, the rotation of the rotating rod 701 and the ball valve 702 is limited, and one of the clamping teeth 1006 is provided with a notch, and the clamping gear 1005 can pass through the notch.

[0048] Working principle: When the device is used to extinguish a fire, the booster pump 1 302 is started, and the booster pump 1 302 forces the foam liquid in the foam storage tank 301 to be introduced into the connecting pipe 1 304 through the foam liquid output pipe 303, and then introduced into the mixing pipe 506 through the connecting pipe 1 304. At the same time, the booster pump 2 402 is started, and the water in the water storage tank 401 is introduced into the connecting pipe 2 404 through the water delivery pipe 403, and then introduced into the mixing pipe 506 through the connecting pipe 2 404, so that the foam liquid and water meet and mix in the mixing pipe 506 to form a foam mixed liquid;

[0049] Start the air compressor 502, so that air enters the air compressor 502 through the air inlet 504, and the air compressor 502 compresses the gas to form compressed air, which is stored in the air storage tank 503, and the compressed air is introduced into the mixing tube 506 through the air outlet pipe 505. When the foam mixture is mixed with the compressed air, foam is generated, and the foam is transported to the mixer 601 through the delivery pipe 602 for further optimization and processing of the foam. When extinguishing a fire, the reel tube 603 is released to the fire location, such as a fire in a lithium battery of a new energy vehicle, and the reel tube 603 is released to the lithium battery, and the foam is sprayed onto the lithium battery through the nozzle 604 by high pressure to extinguish the lithium battery, thereby achieving the effect of compressed air foam fire extinguishing;

[0050] When extinguishing fires of different burning materials, it is necessary to mix foam liquid and water in a certain ratio. For example, in the case of lithium batteries of new energy vehicles or traffic accidents, the appropriate ratio can reduce the fire extinguishing time and improve the fire extinguishing effect. Therefore, the selection of the ratio of foam liquid to water is particularly important.

[0051] When the ball valve 702 is uniformly adjusted, the electric push rod 901 is started, and the output end of the electric push rod 901 drives the connecting plate 902 to move, so that the connecting plate 902 drives the transmission rod 903 to move, so that the synchronous gear 2 904 is meshed with the two synchronous gears 1 703, and the rotating gear 2 905 is separated from the rotating gear 1 704, and the limit gear 906 slides in the limit gear ring 803, and the limit gear 906 is always meshed with the limit gear ring 803; the output end movement of the electric push rod 901 drives the connecting block 1104 to move, so that the two transmission gears 1103 are separated from the spur rack 1105, and the two engaging teeth 1006 are separated from the engaging gear 1005, that is, the meshing of the synchronous gear 2 904 and the synchronous gear 1 703 controls the rotation and engagement of the ball valve 702;

[0052] During unified adjustment, the motor 801 is started, the output shaft of the motor 801 rotates to drive the rotating drum 802 to rotate, the rotating drum 802 rotates to drive the limit gear ring 803 to rotate, forcing the limit gear to rotate, the limit gear 906 rotates to drive the transmission rod 903 to rotate, the transmission rod 903 drives the synchronous gear 2 904 to rotate, the synchronous gear 2 904 rotates to drive the two synchronous gears 1 703 to rotate, because the two transmission gears 1 1103 and the spur rack 1 1105 are in a separated state, the two synchronous gears 1 703 are forced to rotate to drive the two ball valves 702 to rotate synchronously, and adjust the opening of the ball valve 702, thereby completing the unified adjustment of the ball valve 702;

[0053] When one of the ball valves 702 is adjusted independently, the electric push rod 901 is started in the reverse direction, so that the output end of the electric push rod 901 drives the connecting plate 902 to move in the reverse direction, so that the connecting plate 902 drives the transmission rod 903 to move in the reverse direction, so that the synchronous gear 2 904 is separated from the two synchronous gears 1 703, and at the same time, the limit gear 906 slides in the limit gear ring 803, and the limit gear 906 is always meshed with the limit gear ring 803 until the rotating gear 2 905 is meshed with one of the rotating gears 1 704; during the retreat process of the electric push rod 901, before the synchronous gear 2 904 is separated from the two synchronous gears 1 703, The two transmission gears 1103 are meshed with the two spur racks 1105. When the electric push rod 901 continues to retreat, the output end of the electric push rod 901 drives the connecting block 1104 to move, so that the connecting block 1104 drives all the spur racks 1105 to move, forcing the transmission gear 1103 to rotate, the transmission gear 1103 drives the shaft 1102 to rotate, and the shaft 1102 drives the transmission gear 2 1003 to rotate. Under the action of the guide plate 1001, the transmission gear 2 1003 drives the spur rack 2 1002 to retreat along the output end of the electric push rod 901, and the spur rack 2 1002 drives the connecting rod 1004 to rotate. The connecting rod 1004 drives the engaging teeth 1006 to move until the engaging teeth 1006 mesh with the engaging gear 1005, restricting the rotation of the two ball valves 702. At this time, the synchronous gear 2 904 is just separated from the two synchronous gears 1 703. The electric push rod 901 continues to retreat until the rotating gear 2 905 just meshes with one of the rotating gears 1 704. At this time, the first spur rack 1105 drives a transmission gear 1103 to rotate, forcing the shaft 1102 to rotate and drive the transmission gear 2 1003 to rotate, forcing the spur rack 2 1002 to move, forcing the connecting rod 1004 to drive a engaging tooth 1006 to move. The first gear 1006 is moved until the engaging teeth 1006 is disengaged from the engaging gear 1005, so that the engaging gear 1005 is located at the gap, until the rotating gear 2 905 is completely meshed with one of the rotating gears 1 704, at which time a transmission gear 1103 is located between the first spur rack 1105 and the second spur rack 1105, and the transmission gear 1103 is disengaged from the first spur rack 1105; at the same time, the other transmission gear 1103 is always meshed with the third spur rack 1105, so that the engaging teeth 1006 is always meshed with the engaging gear 1005, forming a clamping control effect on the other ball valve 702;

[0054] At this time, the adjustment of one of the ball valves 702 is completed. At this time, the motor 801 is started, and the output shaft of the motor 801 rotates to drive the rotating drum 802 to rotate. The rotating drum 802 rotates to drive the limit gear ring 803 to rotate, forcing the limit gear to rotate. The limit gear 906 rotates to drive the transmission rod 903 to rotate. Since the synchronous gear 1 703 is separated from the synchronous gear 2 904, the transmission rod 903 drives the rotating gear 2 905 to rotate. The rotating gear 2 905 rotates to drive the rotating gear 1 704 to rotate. The rotating gear 1 704 drives the rotating rod 701 to rotate, so that one of the ball valves 702 rotates, and the opening of one of the ball valves 702 is independently adjusted.

[0055] When one of the ball valves 702 is adjusted independently, the electric push rod 901 is started in the reverse direction, and the output end of the electric push rod 901 drives the rotating gear 2 905 to separate from one of the rotating gears 1 704, so that the rotating gear 2 905 continues to move and meshes with the other rotating gear 2 905; in the retreat process, the output end of the electric push rod 901 drives the connecting block 1104 to move, so that the connecting block 1104 drives all the straight racks 1 1105 to move, and before the rotating gear 2 905 is separated from one of the rotating gears 1 704, the second straight rack 1105 is engaged with the rotating gear 1 1105. 05 meshes with one of the transmission gears 1103. When the rotating gear 2 905 is just separated from one of the rotating gears 1 704, the second spur rack 1105 drives one of the transmission gears 1103 to rotate, so that under the action of the shaft 1102, the spur rack 1002, the transmission gear 1003 and the connecting rod 1004, the engaging teeth 1006 mesh with the engaging gear 1005 again. At this time, the rotating gear 2 905 and the rotating gear 1 704 are both separated, and the two engaging teeth 1006 are both meshed with the engaging gear 1005.

In this process, one of the transmission gears 1103 is forced to mesh with the second spur rack 1105, so that one of the engaging teeth 1006 is meshed with the engaging gear 1005, and at the same time, another transmission gear 1103 is meshed with the third spur rack 1105. Under the action of the shaft 1102, the spur rack 1002, the transmission gear 1003 and the connecting rod 1004, the other engaging tooth 1006 exceeds the engaging gear 1005, that is, the other engaging tooth 1006 is separated from the engaging gear 1005. At this time, the adjustment of the other ball valve 702 is completed; at this time, the motor 801 is started, and the output shaft of the motor 801 rotates to drive the rotating drum 802 to rotate, and the rotation of the rotating drum 802 drives the limit gear ring 803 to rotate, forcing the limiting gear to rotate, and the limit gear 906 rotates to drive the transmission rod 903 to rotate. Since the synchronous gear 1 703 is separated from the synchronous gear 2 904, the transmission rod 903 drives the rotating gear 2 905 to rotate, and the rotating gear 2 905 rotates to drive another rotating gear 1 704 to rotate, and the rotating gear 1 704 drives the rotating rod 701 to rotate, thereby causing the other ball valve 702 to rotate, and completing the independent adjustment of the opening of the other ball valve 702.
