DETAILED DESCRIPTION

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0057] As shown in Figures 1-20, according to the embodiment of the present application, the fire extinguishing device comprises a fire retardant mechanism 30 and a support mechanism 10.

[0058] The fire-retardant mechanism 30 comprises a receiving member and an isolation member 31, the isolation member 31 has an unfolded state and a folded state, and the receiving member can switch the isolation member 31 from the folded state to the unfolded state. The support mechanism 10 comprises a moving frame 11, the fire-retardant mechanism 30 is arranged on the moving frame 11, and the moving frame 11 can move to the on-fire vehicle, and the isolation member 31 is switched from the folded state to the unfolded state to isolate the on-fire vehicle.

[0059] It should be noted that in actual application, the vehicle transport ship can be a roll-on / roll-off ship, and the vehicles are placed in the cabin of the roll-on / roll-off ship. Due to the narrow space in the cabin of the roll-on / roll-off ship and the dense arrangement of the vehicles, if a vehicle catches fire during transportation, the chain thermal runaway reaction of the lithium battery may occur, which affects the vehicles in the cabin to different degrees, and thus it is difficult to effectively control the fire.

[0060] Based on this, as shown in FIGS. 1-5, the fire extinguishing device of the embodiment comprises a detector, a fire-retardant mechanism 30, a spraying mechanism 20, an AGV fire extinguishing trolley 50 and a support mechanism 10.

[0061] The detector detects the on-fire vehicle in the cabin of the vehicle transport ship and sends a warning signal, and the central control console 42 of the fire extinguishing device can receive the warning signal to determine the specific position of the vehicle by calculation. The detector can be installed on the spraying mechanism 20, the detector can be installed on the AGV fire extinguishing trolley 50, or the detector can be installed on each vehicle.

[0062] The central control console 42 is installed on the moving frame 11 and is used for receiving, transmitting signals and controlling related mechanisms, such as the fire-retardant mechanism 30 and the spraying mechanism 20. At the same time, the driving motor 41 is installed on the moving frame 11 and serves as the power source of the moving frame 11.

[0063] The support mechanism 10 comprises a moving frame 11, and the moving frame 11 can move to the on-fire vehicle.

[0064] As shown in FIG. 4, the spraying mechanism 20 is installed on the moving frame 11. The spraying mechanism 20 can comprise a first infrared camera 21, an electromagnetic valve, a first high-pressure fine water mist nozzle 23, a second high-pressure fine water mist nozzle 24, a water pipe quick connector 22 and a high-pressure explosion-proof hose. The high-pressure explosion-proof hose is stretched and retracted by an automatic pipe retractor, and the end thereof is connected to the water pipe quick connector 22. The electromagnetic valve is installed on the high-pressure explosion-proof hose and is used for controlling the start and stop of the spraying mechanism 20. The first infrared camera 21 is used for monitoring the vehicle and the surrounding temperature change in real time. The front end of the camera is provided with high-temperature-resistant waterproof glass to prevent the high-temperature smoke and the fine water mist from damaging the first infrared camera 21.

[0065] The first infrared camera 21 is arranged in the middle of the mobile frame 11 and faces downward. The first infrared camera 21 can monitor the on-fire vehicle in real time and continuously transmit the vehicle state and temperature change to the central control console 42. The spray angle of the first and second high-pressure water mist nozzles is 90°-120°, the spray liquid is solid cone, and the spray mode is from top to bottom. The water mist sprayed in this way can suffocate the on-fire vehicle and continuously cool the on-fire battery and the surrounding environment.

[0066] As shown in FIG. 1, the fire-retardant mechanism 30 is installed on the mobile frame 11. The fire-retardant mechanism 30 includes a receiving member and a separation member 31 having an unfolded state and a folded state, and the receiving member enables the separation member 31 to switch from the folded state to the unfolded state. In this way, on the basis of spraying the on-fire vehicle, the fire-retardant mechanism 30 separates the on-fire vehicle from the surrounding non-on-fire vehicles, and the separation member 31 can effectively prevent the spread of fire. In this way, the chain reaction of surrounding vehicles being ignited is avoided, the fire is controllable and easier to extinguish, the property loss is reduced, and a safe and reliable vehicle storage environment in the vehicle transport ship is ensured.

[0067] As shown in FIGS. 18-20, the AGV fire extinguishing trolley 50 has a front-facing and upward-facing second infrared camera 55. High-temperature-resistant and waterproof glass is installed on the upper surface of the second infrared camera 55 to prevent high temperature and fire extinguishing agent from damaging the infrared camera. The signal receiver of the AGV fire extinguishing trolley 50 obtains the early warning signals (smoke sensor alarm, temperature sensor alarm, and BMS alarm) of the on-fire vehicle and obtains the positioning signal, and can accurately move to the bottom of the on-fire vehicle. When the AGV fire extinguishing trolley 50 receives the early warning signal, it immediately starts and advances along the predetermined route to the accurate position of the on-fire vehicle. In addition, the AGV fire extinguishing trolley 50 is built-in with two sets of spraying systems: one is a foam fire extinguishing agent spraying system, which sprays foam through multiple foam nozzles 51 arranged on the top of the AGV fire extinguishing trolley 50, and is used for extinguishing open flames in the early stage. The second is a high-pressure water mist spraying system, which sprays water mist through multiple water mist nozzles 52 arranged on the side wall of the AGV fire extinguishing trolley 50, and is used for continuously cooling the on-fire vehicle and the surrounding area in the middle and late stages. Among them, the angle between the water spraying direction of the water mist nozzle and the vertical direction is 30°-60°, specifically, the angle between the water spraying direction of the water mist nozzle and the vertical direction is 45°.

[0068] An electromagnetic valve is arranged in front of the two fire extinguishing agent storage tanks (foam fire extinguishing agent / water) for controlling the switching of the fire extinguishing agent in the transport pipe. At the same time, a three-way reversing valve 53 is used to switch the on-off of the two sets of spraying system pipelines inside the AGV fire extinguishing trolley 50. A quick plug 54 is arranged at the rear end of the AGV fire extinguishing trolley 50, which is mainly used for quick plug connection with the high-pressure explosion-proof hose. The high-pressure explosion-proof hose is stretched and rolled by an automatic pipe stretcher, and the automatic pipe roller is installed on the side chord of the cabin.

[0069] To sum up, the embodiment of the present application can suffocate and cool the on-fire vehicle through the spraying mechanism; the fire spreading can be prevented through the fire-retardant mechanism, so as to avoid the chain reaction of the surrounding vehicles being ignited, and the fire can be controlled; the AGV fire-fighting trolley can enter the bottom of the vehicle to precisely spray the high-temperature area of the out-of-control battery pack of the on-fire vehicle, so as to prevent the rekindling; meanwhile, the AGV fire-fighting trolley has the ability of rapid response, and can quickly maneuver after receiving the positioning signal, which is incomparable to the traditional fire-fighting equipment, and can ensure that the fire or potential fire can be controlled in the first time. In this way, under the triple action, the fire of the on-fire vehicle can be efficiently and timely controlled, the chain reaction of the surrounding vehicles being ignited can be avoided, and the fire spreading and the fire spreading can be effectively prevented.

[0070] In some embodiments of the present application, the fire-retardant mechanism 30 further comprises a telescopic piece 32, and the isolation piece 31 in the folded state is in a closed shape. The telescopic piece 32 can adjust the circumference of the closed shape, or / and change the shape of the closed shape.

[0071] It should be noted that the isolation piece 31 in the folded state is in a circumferentially closed shape, and the closed shape can be circular, rectangular, square, oval, or other regular polygon, which will not be enumerated one by one in the embodiment.

[0072] Of course, it can be understood that the isolation piece 31 in the folded state can be in a circumferentially non-closed shape, for example, L-shaped, U-shaped, etc.

[0073] In actual application, the length and width of the vehicle are various, based on which, the isolation piece 31 in the folded state can adjust its circumference or shape through the telescopic piece 32 to surround vehicles of different sizes, so as to more effectively prevent the fire spreading.

[0074] In the first embodiment, as shown in FIGS. 5-8, the isolation piece 31 in the folded state is divided in the circumferential direction and comprises N separated segments 301 and N wrinkle connecting segments 302, N is a positive integer, N≥2.

Among them, the fireproof blanket corresponding to the separation section 301 can be stored in the above-mentioned direction, as shown in FIGS. 5-10, the fireproof blanket corresponding to the separation section 301 is stored by the storage roller 34, and correspondingly, since each wrinkle connecting section 302 is connected by two separation sections 301, and each wrinkle connecting section 302 is also stored under the action of the storage roller 34, so as to realize the winding storage of the wrinkle connecting section 302.

[0080] In another embodiment, as shown in FIG. 14, the storage member can be a connecting frame 39, a plurality of magnetic members 37 and a plurality of electromagnetic members 38, and the plurality of electromagnetic members 38 are connected to the connecting frame 39.

The electromagnetic member 38 generates a magnetic field when powered on, and the fireproof blanket is switched from the folded state to the unfolded state by being powered off. The electromagnetic buckle is simple and convenient. Among them, the fireproof blanket corresponding to the wrinkle connecting section 302 and the separation section 301 can be stored in this way.
