[0043] like Figure 1 As shown, a fire extinguishing device 100 provided in one embodiment of the present invention includes a frame assembly 110 and a fire hose 120.

[0044] The frame assembly 110 includes two foldable frames 111 arranged side by side and spaced apart along a first direction.

[0045] It should be noted that the first direction is parallel to the horizontal plane, and the two foldable frames 111 are arranged side by side and spaced apart along the first direction. The foldable frames 111 can be folded or unfolded along the second direction. It should also be noted that the second direction is perpendicular to the first direction and is also parallel to the horizontal plane.

[0046] Combination Figure 1 and Figure 2 Furthermore, each foldable frame 111 includes multiple vertical support rods 1111 spaced apart and arranged side by side along the second direction, and a foldable linkage mechanism 1112 disposed between each two adjacent vertical support rods 1111.

[0047] Specifically, the foldable linkage mechanism 1112 is used to connect the two vertical support rods 1111 connected thereto, and the two vertical support rods 1111 connected thereto can be brought closer or further apart, thereby realizing the foldable frame 111 folding or unfolding in the second direction.

[0048] Specifically, the foldable linkage mechanism 1112 includes two intersecting and rotatably connected links 11121; specifically, the two links 11121 are arranged in an 'X' shape, and the middle part of one link 11121 is rotatably connected to the middle part of the other link 11121. In particular, the middle part of one link 11121 is rotatably connected to the middle part of the other link 11121 through a pivot.

[0049] Furthermore, in the two vertical support rods 1111 arranged adjacent to each other along the second direction, and the foldable linkage mechanism 1112 located between the two vertical support rods 1111: one end of one linkage 11121 is rotatably and slidingly engaged with one of the vertical support rods 1111, and the other end is rotatably and slidingly engaged with the other vertical support rod 1111; one end of the other linkage 11121 is rotatably and slidingly engaged with one of the vertical support rods 1111, and the other end is rotatably and slidingly engaged with the other vertical support rod 1111.

[0050] Specifically, in the two adjacent vertical support rods 1111 arranged along the second direction, and the foldable linkage mechanism 1112 located between the two vertical support rods 1111: one end of one linkage 11121 can rotate relative to one of the vertical support rods 1111 and can also move relative to the length direction of the vertical support rod 1111, and the other end of the linkage 11121 can rotate relative to the other vertical support rod 1111 and can also move relative to the length direction of the vertical support rod 1111; one end of the other linkage 11121 can rotate relative to one of the vertical support rods 1111 and can also move relative to the length direction of the vertical support rod 1111, and the other end of the linkage 11121 can rotate relative to the other vertical support rod 1111 and can also move relative to the length direction of the vertical support rod 1111. Thus, relying on the foldable linkage mechanism 1112, the foldable frame 111 can be folded or unfolded in the second direction.

[0051] Combination Figure 2 and Figure 3 Furthermore, the connection structure between the connecting rod 11121 of the foldable linkage mechanism 1112 and the vertical support rod 1111 is as follows:

[0052] A vertical guide rail 1113 is provided on the vertical support rod 1111. The vertical guide rail 1113 is provided with a vertical guide groove 11131 extending vertically. A connecting shaft 11122 is provided in the vertical guide groove 11131. The connecting shaft 11122 can move along the extension direction of the vertical guide groove 11131. Furthermore, the vertical guide groove 11131 can also prevent the connecting shaft 11122 from coming out. The connecting shaft 11122 passes through the end of the connecting rod 11121 so that the connecting rod 11121 can rotate relative to the vertical support rod 1111.

[0053] Furthermore, the vertical guide rail 1113 is also provided with a horizontal limiting groove that communicates with the vertical guide groove 11131. When the foldable frame 111 is unfolded to a preset length, the connecting rod 11121 is engaged with the horizontal limiting groove for limiting the foldable frame 111 from continuing to unfold.

[0054] Specifically, the lateral limiting groove is set perpendicular to the vertical guide groove 11131. When the foldable frame 111 is unfolded to a preset length, the connecting shaft 11122 at the end of the connecting rod 11121 passes through the lateral limiting groove. The lateral limiting groove is used to restrict the foldable frame 111 from continuing to unfold. The connecting shaft 11122 can be moved from the lateral limiting groove into the vertical guide groove 11131, thus allowing the unfolded foldable frame 111 to fold.

[0055] like Figure 4 As shown, the multiple vertical support rods 1111 are all hollow structures with water flow channels, and the inner side of the vertical support rods 1111 is provided with a water nozzle 11111 that communicates with the water flow channels. Specifically, the vertical support rods 1111 are hollow structures with sealed top and bottom ends, and have water flow channels inside. Furthermore, the inner side of the vertical support rods 1111 is provided with a water nozzle 11111 that communicates with the water flow channels. It should be noted that the inner side of the vertical support rods 1111 refers to the side closest to the other foldable frame 111.

[0056] like Figure 1 As shown, the fire hose 120 is connected to the frame assembly 110, and the fire hose 120 is connected to the water flow channels of multiple vertical support rods 1111 on the two foldable frames 111.

[0057] Understandably, the fire hose 120 not only connects the two foldable frames 111, but also connects the water flow channels of multiple vertical support rods 1111 of the two foldable frames 111. When water is supplied, water will enter the water flow channels of each vertical support rod 1111 along the fire hose 120, and then be sprayed out through the nozzles 11111 to achieve the effect of extinguishing the fire.

[0058] When not in use, each foldable frame 111 of the fire extinguishing device 100 of this utility model can be folded to reduce the space occupied. When in use, the foldable frame 111 is unfolded so that the two foldable frames 111 are placed on both sides of the burning object (e.g., a vehicle), and then water is turned on so that water is sprayed out through the water nozzles 11111 of each vertical support rod 1111 to achieve the effect of extinguishing the fire.

[0059] like Figure 4 As shown, it should be noted that a water inlet pipe connector 1116 can be installed on at least one vertical support rod 1111. The water inlet pipe connector 1116 can be connected to a water inlet pipe. When the water inlet pipe is connected to the water inlet pipe connector 1116, the water inlet pipe is connected to the water flow channel of each vertical support rod 1111 and the fire hose 120. The water in the water inlet pipe can be injected into the fire extinguishing device 100 to achieve the effect of spraying water.

[0060] Of course, in other embodiments, water can be supplied into the fire hose 120 so that the water enters the water flow channel of each vertical support 1111 and sprays out from each nozzle 11111.

[0061] like Figure 1 As shown, it should be noted that the fire hose 120 includes multiple first connecting sections 121; among the multiple vertical supports 1111 in the same foldable frame 111, each pair of adjacent vertical supports 1111 is connected by a first connecting section 121, and the water flow channels of the first connecting section 121 and the two vertical supports 1111 connected thereto are connected; thus, in each foldable frame 111, the water flow channels of the multiple vertical supports 1111 within the foldable frame 111 can be connected by means of the first connecting section 121.

[0062] Combination Figure 1 and Figure 6 Specifically, each of the multiple vertical support rods 1111 is provided with a first adapter 1114, and the first connecting section 121 between two adjacent vertical support rods 1111 is respectively connected to the first adapter 1114 of the two adjacent vertical support rods 1111, so that the first connecting section 121 and the water flow channel of the two vertical support rods 1111 connected thereto are connected.

[0063] like Figure 1 As shown, the fire hose 120 further includes at least one second connecting section 122, which connects the two foldable frames 111 and connects the vertical support rods 1111 between the two foldable frames 111.

[0064] Combination Figure 1 and Figure 6Understandably, each foldable frame 111 is equipped with a second adapter 1115. Specifically, at least one vertical support rod 1111 of one foldable frame 111 is equipped with a second adapter 1115, and at least one vertical support rod 1111 of the other foldable frame 111 is equipped with a second adapter 1115. One end of the second connecting section 122 is connected to the second adapter 1115 of one foldable frame 111, and the other end is connected to the second adapter 1115 of the other foldable frame 111. In this way, the water flow channels of multiple vertical support rods 1111 of the two foldable frames 111 can be connected by means of the second connecting section 122.

[0065] Combination Figure 1 and Figure 4 Furthermore, the frame assembly 110 also includes a foldable lateral support mechanism 113 connected between the two foldable frames 111, the foldable lateral support mechanism 113 being used to connect the two foldable frames 111.

[0066] Specifically, the foldable lateral support rod mechanism 113 includes two lateral support rods 1131. One end of one lateral support rod 1131 is rotatably connected to one of the foldable frames 111, and the other end is rotatably connected to one end of the other lateral support rod 1131. The other end of the other lateral support rod 1131 is rotatably connected to another foldable frame 111. The foldable lateral support rod mechanism 113 can be folded and unfolded along a first direction.

[0067] It should be noted that when the fire hose 120 is filled with water, it can straighten under water pressure. Therefore, when the foldable frame 111 and the foldable transverse support mechanism 113 are in the folded state, the fire hose 120 straightens after being filled with water, which allows the foldable frame 111 and the foldable transverse support mechanism 113 to automatically unfold.

[0068] In some embodiments, each vertical support rod 1111 is further provided with a roller at its bottom, and the roller may be a non-directional roller.

[0069] Combination Figure 7 and Figure 8 Furthermore, the foldable frame 111 is also provided with an auxiliary support mechanism 140, which is rotatably connected to the foldable frame 111 so that the auxiliary support mechanism 140 can be folded and unfolded.

[0070] Understandably, the auxiliary support mechanism 140 can provide auxiliary support after unfolding, reducing the risk of the foldable frame 111 tipping over.

[0071] Specifically, the auxiliary support mechanism 140 can rotate in the horizontal plane relative to the foldable frame 111, and the bottom of the auxiliary support mechanism 140 is provided with rollers.

[0072] Combination Figure 7 and Figure 8 Furthermore, the fire extinguishing device 100 also includes a fireproof cloth 130, which covers the frame assembly 110. The fireproof cloth 130 is a high-temperature resistant material, and its material can be any material with a high temperature resistance between 200℃ and 1200℃. The fireproof cloth 130 can play a role in isolating air.

[0073] like Figure 5 As shown, this utility model also provides a fire extinguishing system, including a transport device 200, a water supply device 300, and the fire extinguishing device 100 of the above embodiment.

[0074] The transport device 200 can serve a transport function; the water supply device 300 is mounted on the transport device 200 and can be transported by the transport device; the fire extinguishing device 100 is mounted on the transport device 200 and can be removed from the transport device; the water supply device 300 is used to supply water to the fire extinguishing device 100.

[0075] When a vehicle catches fire, the transport device 200 can move the water supply device 300 and the fire extinguishing device 100 to the vicinity of the fire location, and then cover the burning vehicle with the fire extinguishing device 100, and supply water to the fire extinguishing device 100 through the water supply device 300, thereby achieving the purpose of isolating the burning material, preventing the fire from spreading and automatically extinguishing the fire.

[0076] In some embodiments, the transport device 200 includes a transport vehicle 210, and a water supply device 300 is mounted on the transport vehicle 210. The water supply device 300 includes a water tank 310 and a booster pump 320. The water tank 310 has an inlet and an outlet. The inlet is located at the top of the water tank 310, and the outlet is located at the bottom of the water tank 310. The outlet is connected to the inlet of the booster pump 320, and the outlet of the booster pump 320 is connected to an inlet pipe connector 1116 via an inlet pipe. When the booster pump 320 is working, it can pump water from the water tank 310 into the fire extinguishing device 100. It should be noted that the booster pump 320 can be started manually or electrically. The water supply device 300 may also include a backup power supply mounted on the transport vehicle 210.

[0077] Combination Figure 5 and Figure 6 Furthermore, the transport device 200 also includes a support platform 220 connected to the transport vehicle 210, on which the fire extinguishing device 100 can be placed. The support platform 220 is equipped with a fence to protect the fire extinguishing device 100.

[0078] Furthermore, the transport device 200 also includes a descent guide rail 230 connected to the support platform 220. The descent guide rail 230 has a working state. When the descent guide rail 230 is in working state, it is tilted, with its front end connected to the rear end of the support platform 220, and its rear end lower than its front end. Thus, when it is necessary to remove the fire extinguishing device 100 from the support platform 220, the fire extinguishing device 100 can be removed along the descent guide rail 230.

[0079] Understandably, when the descent guide 230 is not in use, it is placed on the support platform 220 to prevent it from touching the ground.

[0080] It should be noted that the transport vehicle 210 can be a motorized device or a manually towed device.

[0081] When a vehicle catches fire, the transport device 200 can move the water supply device 300 and the fire extinguishing device 100 to the vicinity of the fire location. Then, the slow-descent guide rail 230 is switched to the working state. After that, the booster pump 320 works to pump water from the water tank 310 into the fire hose 120. The fire hose 120 is straightened, which can drive the fire extinguishing device 100 to unfold in the first direction. In addition, by making the fire extinguishing device 100 unfold in the second direction and making the fire extinguishing device 100 unload along the slow-descent guide rail 230, the foldable frame 111 can be placed on both sides of the vehicle, and the fireproof cloth 130 covers the vehicle. The water pumped into the fire extinguishing device 100 can be sprayed out through the spray nozzle 11111, thereby achieving the purpose of isolating the burning material, preventing the spread of fire, and automatically extinguishing the fire.

[0082] Furthermore, the fire extinguishing system also includes multiple water baffles placed on the support platform 220, the multiple water baffles being configured to be spliced ​​together and enclosed to form a water storage tank.

[0083] Understandably, multiple water deflectors can be removed from the support platform 220. When the fire extinguishing device 100 covers the fire location, a water storage tank can be constructed around the fire extinguishing device 100 using the water deflectors. This water storage tank can store water to soak the vehicle's battery, thereby achieving cooling and fire extinguishing, and further suppressing battery thermal runaway.
