Technical Field

[0002] With the rapid development of new energy vehicles, the number of new energy vehicles transported by car carriers has also increased significantly. Once a new energy vehicle catches fire during transportation, it is very easy to cause the fire to spread and cause serious casualties and property losses. Therefore, fire risk control of car carriers has become particularly important.

[0003] In order to transport vehicles in large quantities, car carriers generally have multiple parking decks. Each parking deck needs to park multiple cars, and the distance between cars is extremely small. However, existing fire trucks are large in size and cannot move freely on the parking deck, so they are not suitable for fire fighting on the parking deck. Utility Model Content

DETAILED DESCRIPTION

[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] Glossary:

[0049] Car carrier: a ship specially designed for transporting vehicles, which is generally equipped with multiple decks, including fixed decks and movable decks. The movable deck is generally set between the fixed decks, and the position of the movable deck is adjustable to adjust the distance between it and the adjacent deck according to the parked vehicles, so that it can adapt to the parking of a variety of different vehicles. Each deck is usually connected by an internal ramp, and the deck is usually equipped with fixings and protective equipment to ensure that the vehicle will not move or be damaged during transportation.

[0050] New energy vehicles: refers to vehicles that use new power systems and are completely or mainly driven by new energy. The main types of new energy vehicles currently include pure electric vehicles, plug-in hybrid vehicles, hybrid vehicles, fuel cell vehicles, extended-range electric vehicles, etc. These vehicles generally need to be equipped with battery packs to store and provide electrical energy, and the battery packs are generally arranged under the vehicle's chassis, under the trunk, in the central aisle, under the seats, etc., that is, the battery packs are generally located at the bottom of the vehicle.

[0051] A fire truck is a commonly used fire-fighting tool at present, such as an intelligent fire truck disclosed in the related art, which includes a vehicle body, a base, a high-temperature resistant cover, a control module is also provided above the base, a fire extinguisher accommodating chamber is also provided above the control module, the high-temperature resistant cover covers the fire extinguisher accommodating chamber, an opening is provided on the side of the high-temperature resistant cover, the fire extinguisher nozzle and the conduit extend from the opening, a clamping mechanism is provided at the opening outside the high-temperature resistant cover, the clamping mechanism clamps the conduit to control the direction of the fire extinguisher nozzle, and a high-temperature resistant driving mechanism is provided at the lower part of the base, and the driving mechanism controls the movement of the vehicle body. The high-temperature resistant driving mechanism includes universal wheels and high-temperature resistant baffles to meet the needs of long-term mobile use in high-temperature environments for fire-fighting tasks. The clamping mechanism can control the direction of the nozzle to align with the fire source according to the direction of the fire. The control module automatically detects the fire source, adjusts the nozzle direction in time and completes the fire extinguishing action.

[0052] Vehicles with thermal runaway: refers to vehicles whose temperature rises sharply, emits a lot of smoke, and catches fire due to the loss of control of the battery pack. Under certain closed or semi-closed conditions, they may explode or other dangerous vehicles.

[0053] However, for the sea transportation of new energy vehicles, in order to transport a large number of vehicles, car carriers generally have more than a dozen parking decks, and thousands of vehicles are parked in a relatively confined space, with a front-to-back spacing of about 30 cm and a left-to-right spacing of about 10 cm. The above-mentioned fire trucks need to use high-temperature resistant covers and clamping devices, resulting in large body sizes and high heights, which cannot pass between vehicles on the parking deck. This is also the main reason why most fire trucks cannot be used on car carriers.

[0054] At the same time, fires in new energy vehicles during sea transportation are basically caused by battery failures. Lithium batteries continuously react and release a large amount of heat when they are in thermal runaway. The battery pack is placed close to the bottom of the vehicle. The existing fire trucks are basically the same as the above-mentioned fire trucks. They cannot get close to the vehicle with thermal runaway, that is, they cannot cool down the bottom of the vehicle with thermal runaway to reduce the battery's own reaction, and the cooling effect is weak. In addition, the thermal runaway of new energy vehicles currently requires long-term continuous cooling of the battery pack to reduce the possibility of re-ignition. The existing fire trucks basically use a one-time spraying of fire extinguishing agents to extinguish the fire, which is difficult to prevent the battery pack from re-igniting.

[0055] In order to avoid the above problems, the embodiments of the present application provide a fire truck and a car transport ship, wherein the fire truck includes a body and a controller, the height of the body is less than the height of the chassis of the vehicle with thermal runaway, and the width of the body is also less than the distance between the two rear wheels of the vehicle with thermal runaway, so that the body does not need to pass through the gap between the vehicles and can pass freely under the vehicle. At the same time, an injection device and a fire extinguishing agent interface are provided on the body, the fire extinguishing agent interface is connected to a storage system for storing the fire extinguishing agent, and the injection device is connected to the fire extinguishing agent interface, so that the fire extinguishing agent stored in the storage system can enter the injection device through the fire extinguishing agent interface and pass through the fire extinguishing agent interface. The fire extinguishing agent is sprayed out through the spray device. After the controller obtains the position information of the thermal runaway vehicle, it can control the vehicle body to move to the bottom of the thermal runaway vehicle according to the position information, and extinguish the fire and cool down the thermal runaway vehicle from the bottom of the thermal runaway vehicle. The battery pack of the new energy vehicle is at the bottom of the thermal runaway vehicle. Spraying the fire extinguishing agent from the bottom of the thermal runaway vehicle can effectively improve the fire extinguishing and cooling effect. Therefore, after the fire truck provided in the embodiment of the present application is applied to the automobile transport ship, it can not only adapt to the dense arrangement of vehicles on the automobile transport ship, but also can accurately extinguish the fire and cool down the thermal runaway vehicles on the deck, thereby improving the cooling effect.

[0056] See also Figure 1 and Figure 2 As shown, this embodiment provides a fire truck, which can be applied to a car transport ship, or to other areas similar to the car transport ship for centralized storage of vehicles, such as a garage. This embodiment takes the car transport ship as an example to explain the structure of the fire truck in detail. The fire truck includes a body 100 and a controller 150.

[0057] The height of the vehicle body 100 is less than the height of the chassis of the vehicle 10 parked on the thermal deck, and the width of the vehicle body 100 is less than the distance between the two rear wheels of the vehicle 10 parked on the deck, so that the vehicle body 100 can pass through the bottom of other vehicles 10 on the path and move to the bottom of the thermal runaway vehicle 10. Specifically, the chassis heights of different types of vehicles are not the same at present, and the chassis heights of some vehicles may reach more than 20 centimeters, while the chassis heights of some vehicles are lower, which may be only more than 10 centimeters. At the same time, the widths of different types of vehicles are also different, and the distances between the rear wheels are not the same. Therefore, the width and height of the vehicle body 100 can be designed according to the type of vehicle 10 parked on the deck 20.

[0058] In actual applications, the height of the vehicle body 100 can be set to 15 cm or less, for example, 12 cm, which can basically avoid the chassis of most vehicles on the market. The width of the vehicle body 100 does not actually need to be too large, so it can be designed to be much smaller than the distance between the rear wheels of vehicles on the market. Of course, this is just an example, not a limitation on the size of the vehicle body 100.

[0059] Among them, the vehicle body 100 is provided with a spray device 110 and a fire extinguishing agent interface 120. The fire extinguishing agent interface 120 is used to connect a storage system for storing fire extinguishing agents. The storage system can be connected to the fire extinguishing agent interface 120 through a hose. When the vehicle body 100 moves, the hose has a strong deformability and can adapt to the moving path of the vehicle body 100. At the same time, the fire extinguishing agent can be selected from common water, foam fire extinguishing agents, etc. that can be transported through pipelines and are suitable for battery pack fire extinguishing and cooling. The fire extinguishing agent interface 120 is connected to the spray device 110 to feed the fire extinguishing agent into the spray device 110 for spraying. The spraying area of ​​the spray device 110 at least includes the bottom of the thermal runaway vehicle 10 to continuously cool the battery pack. Of course, the spraying area of ​​the spray device 110 can also include the surrounding area of ​​the thermal runaway vehicle 10 to block the spread of the fire.

[0060] The controller 150 can be connected to the control system of the car transport ship, that is, the controller 150 can be equipped with a signal receiver for receiving the signal sent by the control system. At present, car transport ships are generally equipped with fire monitoring systems. For example, smoke alarms, temperature alarms, BMS alarms and other sensor devices are arranged in various areas. Once a vehicle 10 is found to be in thermal runaway, the sensor device in the corresponding area will send a signal to the control system, and the control system will transmit the coordinates of the corresponding accident area to the controller 150. The controller 150 controls the vehicle body 100 to move to the accident area for fire extinguishing and cooling, so that only a small number of fire trucks are needed on each deck 20 to complete the maintenance of multiple vehicles 10 on the entire deck 20. It can be understood that how the control system determines the position information of the thermal runaway vehicle 10 and transmits it to the controller 150, and how the controller 150 controls the movement of the vehicle body 100 according to the position information are all relatively mature existing technologies in the field, and this embodiment will not be repeated here.

[0061] Specifically, after the controller 150 obtains the position information of the vehicle 10 with thermal runaway, it will control the vehicle body 100 to pass through the bottom of other vehicles 10 on the moving path and move to the bottom of the vehicle 10 with thermal runaway according to the position information, and can transmit a signal to the storage system, or transmit a signal to the control system, and the control system controls the storage system to release the fire extinguishing agent, so that the fire extinguishing agent enters the injection device 110 through the fire extinguishing agent interface 120 for injection, so as to extinguish the fire and cool down the vehicle 10 with thermal runaway. This makes the fire truck of this embodiment adaptable to use in areas with densely arranged vehicles, and can continuously cool down the battery pack from the bottom of the vehicle to prevent the battery pack from re-igniting, effectively improving the ability to control the fire.

[0062] It can be understood that the controller 150 in this embodiment can be a controller set up separately for each fire truck, or it can be directly the control system of the car transport ship. In this case, it is only necessary to install a signal receiver on the vehicle body 100 to control the signal of the system, and install a signal transmitter to transmit the information that the vehicle body 100 needs to feedback to the control system. Whether to set up a separate controller 150 or to use the control system of the car transport ship directly as the controller 150 can be selected according to actual conditions, and this embodiment does not limit it here.

[0063] For some possible implementations, see Figure 2 As shown, a detection device can also be provided on the vehicle body 100, and the detection device is used to collect first information in front of the vehicle body 100 and second information above the vehicle body 100. The detection device is connected to the controller 150. After receiving the first information and the second information, the controller 150 controls the vehicle body 100 to adjust its position so that the vehicle body 100 moves to under the battery pack of the vehicle 10 with thermal runaway, so as to accurately cool the battery pack.

[0064] Among them, the detection device may include a first infrared camera 171 and a second infrared camera 172. The first infrared camera 171 is used to collect first information in front of the vehicle body 100, and the second infrared camera 172 is used to collect second information above the vehicle body 100. The first infrared camera 171 and the second infrared camera 172 are both connected to the controller 150.

[0065] Specifically, after the controller 150 receives the position information sent by the control system, it moves to the vicinity of the vehicle 10 with thermal runaway, and the first infrared camera 171 can identify the abnormal temperature area in front of the vehicle body 100, so that the car moves towards the area with the highest temperature. When approaching the bottom of the vehicle 10 with thermal runaway, the second infrared camera 172 is activated to identify the abnormal temperature area above the vehicle body 100. The battery pack is the source of fire. Therefore, as long as the vehicle body 100 moves to the area with the highest temperature, the battery pack of the vehicle 10 with thermal runaway can be located, thereby achieving precise cooling of the abnormal temperature area of ​​the battery pack.

[0066] The vehicle body 100 is provided with a shell 130, and in order to protect the first infrared camera 171 and the second infrared camera 172, the first infrared camera 171 and the second infrared camera 172 can be installed inside the shell 130, and the cameras of the first infrared camera 171 and the second infrared camera 172 are flush with the edge of the shell 130 of the vehicle body 100, and high-temperature resistant and waterproof glass is installed in the shooting area corresponding to the camera. The high-temperature resistant and waterproof glass can protect the first infrared camera 171 and the second infrared camera 172 from being damaged by high temperature and fire extinguishing agents, and will not affect the first infrared camera 171 and the second infrared camera 172 from obtaining external information.

[0067] It is understandable that the vehicle body 100 may also be made of high temperature resistant and corrosion resistant materials to prevent the fire extinguishing agent from corroding the vehicle body 100 and also prevent the vehicle body 100 from being deformed due to high temperature.

[0068] In addition, the detection device may also be other equipment, as long as it can identify the location of the battery pack of the thermal runaway vehicle 10 based on information such as temperature or image, and this embodiment does not limit it here.

[0069] In some possible embodiments, in addition to the outer shell 130, the vehicle body 100 also includes at least one retractable wheel set 140. The retractable wheel set 140 is communicatively connected to the controller 150. The controller 150 is used to control the retractable wheel set 140 to move to the bottom of the outer shell 130 to drive the outer shell 130 to move, or to control the retractable wheel set 140 to retract into the inner part of the outer shell 130, thereby reducing the height of the entire vehicle body 100 and making the spraying area of ​​the spray device 110 larger.

[0070] Specifically, the retractable wheel set 140 includes an electric control spring 142, a transmission shaft 143 and wheels 141 located at both ends of the transmission shaft 143. One end of the electric control spring 142 is connected to the transmission shaft 143, and the other end is connected to the top of the housing 130. The electric control spring 142 is connected to the controller 150 for communication. The controller 150 is also used to control the extension or shortening of the electric control spring 142. A through hole is provided on the bottom plate of the housing 130 for the wheel 141 to pass through. When the electric control spring 142 is extended, the wheel 141 is pushed through the through hole to at least partially extend outside the housing 130, and the wheel 141 is The shell 130 is lifted as a whole, and the driving assembly drives the wheel 141 to rotate, so that the vehicle body 100 can be moved. When the electric control spring 142 is shortened, the force pushing the wheel 141 disappears, the shell 130 moves down, and the wheel 141 retracts into the inside of the shell 130. The bottom plate of the shell 130 directly contacts the deck 20. At this time, the height of the vehicle body 100 can be lowered. Since the injection device 110 is too close to the bottom of the vehicle, it will affect the effective injection range. Therefore, by retracting the wheel 141, the distance between the injection port of the injection device 110 and the bottom of the vehicle can be increased, thereby effectively expanding the injection range.

[0071] It is understandable that the retractable wheel group 140 can also be other structures, such as driving the transmission shaft 143 through a retractable electric cylinder, a hydraulic cylinder, a pneumatic cylinder, etc. to drive the wheel 141 to rise or fall. The specific selection can be made according to actual needs, and this embodiment does not limit it here.

[0072] In addition, the vehicle body 100 is also provided with a driving assembly for driving the wheel 141 to rotate, wherein the driving assembly is connected to at least one retractable wheel set 140, so that the wheel 141 of the retractable wheel set 140 can be used as the main driving wheel. How the driving assembly drives the wheel 141 to rotate is well known to those skilled in the art, and will not be described in detail in this embodiment.

[0073] A telescopic rod 144 may be provided, the electric control spring 142 is sleeved outside the telescopic rod 144, one end of the telescopic rod 144 is connected to the transmission shaft 143, and the other end is connected to the top cover of the housing 130, so that the moving direction of the transmission shaft 143 is limited by the telescopic rod 144. The telescopic rod 144 may be in the form of an outer rod and an inner rod, the outer rod is sleeved outside the inner rod, and the depth of the inner rod inserted into the outer rod can be adjusted.

[0074] Furthermore, currently the deck 20 is generally a steel structure, and at least one electromagnet 160 can be set on the bottom plate of the shell 130. The electromagnet 160 is communicated with the controller 150. The controller 150 is also used to control the electromagnet 160 to be powered on or off so that the electromagnet 160 can adsorb or stop adsorbing the deck 20 for placing the vehicle 10.

[0075] Specifically, the electromagnet 160 can be arranged inside or outside the housing 130. Of course, it is better to arrange it inside because the electromagnet 160 needs to be powered. It is convenient to protect it by arranging it inside the housing 130.

[0076] One or more electromagnets 160 may be provided, and the electromagnet 160 is mainly used to be energized and adsorbed on the deck 20 when the wheel 141 retracts into the shell 130, so as to effectively prevent the excessive pressure of the fire extinguishing agent supplied in the initial stage from causing the position of the vehicle body 100 to shift, or causing the vehicle body 100 to shake, thereby affecting the spraying angle of the nozzle and the effective spraying range.

[0077] For example, the bottom plate of the housing 130 is rectangular, and the electromagnets 160 can be arranged at the four corners of the bottom plate of the housing 130, thereby improving the adsorption effect between the electromagnets 160 and the deck 20 and improving the stability of the vehicle body 100. Specifically, when the fire extinguishing agent is just sprayed, the instantaneous impact force generated is very large, and the electromagnets 160 located at the four corners of the bottom plate of the housing 130 can effectively stabilize the position of the vehicle body 100 and prevent the vehicle body 100 from shaking.

[0078] It is understandable that the housing 130 may also be circular or in other shapes, as long as it can pass through the bottom of the vehicle, and this embodiment does not limit this.

[0079] For some possible implementations, see Figure 2 As shown, the fire extinguishing agent is water, and the spraying device 110 includes a plurality of first nozzles 111 for spraying water mist, that is, the first nozzles 111 can be high-pressure fine water mist nozzles to spray fine water mist for spraying and cooling the bottom of the vehicle 10 in thermal runaway.

[0080] Among them, the first nozzle 111 has a first nozzle. Among the first nozzles of the first nozzle 111, at least part of the first nozzles are facing the first direction, and at least part of the first nozzles are facing the second direction. The first direction is directly above the vehicle body 100, and the second direction is diagonally above the vehicle body 100. The first nozzle facing directly above the vehicle body 100 can spray the bottom of the vehicle 10 with thermal runaway, and spray to cool down the bottom of the vehicle 10 with thermal runaway, while the first nozzle facing diagonally above the vehicle body 100 can spray the surroundings of the vehicle 10 with thermal runaway, so as to prevent the vehicle 10 with thermal runaway from affecting the surrounding vehicles 10 and avoid the spread of thermal runaway.

[0081] In addition, the angle between the second direction and the vertical direction can be 30°-60°. When the first nozzle 111 sprays water mist at this angle obliquely upward toward the vehicle body 100, the water mist can effectively cover the surroundings of the thermal runaway vehicle 10 to prevent it from affecting surrounding vehicles and causing more vehicles to thermally runaway.

[0082] At present, there are many holes on the movable deck, and the diameter of the holes is generally about 10 cm. When a vehicle under the movable deck has thermal runaway, the vehicle 10 with thermal runaway will generate a large amount of smoke, and the smoke moves upward, which will affect the vehicle 10 above the movable deck. At this time, a first nozzle 111 facing the bottom of the vehicle body 100 can be set on the vehicle body 100. When a vehicle 10 with thermal runaway appears under the movable deck, the controller 150 receives the position information sent by the control system, moves the vehicle body 100 to above the vehicle 10 with thermal runaway, and controls the first nozzle 111 at the bottom of the vehicle body 100 to spray water mist. The water mist passes through the holes on the movable deck and sprays the top of the vehicle 10 with thermal runaway, thereby effectively controlling the influence of a large amount of hot smoke generated during thermal runaway that propagates upward on the vehicle 10 on the upper deck 20.

[0083] It is understandable that when spraying the vehicle 10 located on the movable deck, there is actually no need to spray the vehicle 10 located under the movable deck. Therefore, a solenoid valve can be added to the first nozzle 111, and the solenoid valve is connected to the controller 150. The controller 150 controls whether the first nozzle 111 is working.

[0084] Of course, adding solenoid valves will increase the number of components and the difficulty of installation accordingly, and starting all the first nozzles 111 at the same time will not actually have any impact on the vehicle 10, so the solenoid valves may not be added, and this embodiment does not limit this.

[0085] For example, Figure 3 As shown, the top of the vehicle 10 is a movable deck. When the vehicle 10 thermally runs away, there is a fire truck at its bottom. The first nozzle 111 on the fire truck sprays the bottom and the outside of the vehicle with a first nozzle facing the first direction and the second direction. There is also a fire truck at the top. The first nozzle 111 at the bottom of the vehicle body 100 sprays the top of the vehicle 10, thereby forming an all-round fine water mist coverage area on the outside of the vehicle 10, effectively suppressing the thermal runaway of the battery pack and continuously cooling the battery pack and the surrounding environment.

[0086] In order to make the high-pressure fine water mist spray the vehicle better, the spray shape of the first nozzle 111 can be made into a solid cone, and the spray angle is between 90° and 120°.

[0087] For some possible implementations, see Figure 2As shown, the vehicle body 100 includes at least one telescopic component 115, and the telescopic component 115 at least partially extends to the outside of the shell 130, that is, the telescopic component 115 can be installed on the outer wall of the shell 130, or can be installed inside the shell 130, which can be determined according to actual conditions. The telescopic component 115 is provided with at least one first nozzle 111 facing the second direction, and the first nozzle 111 is located at the end of the telescopic component 115 located on the outside of the shell 130; the telescopic component 115 is connected to the controller 150, and the controller 150 is also used to control the telescopic component 115 to extend toward the outside of the thermal runaway vehicle 10 when the vehicle body 100 is located under the thermal runaway vehicle 10, and to control the telescopic component 115 to retract after the spraying is completed.

[0088] Specifically, the chassis of the vehicle 10 is relatively low. After the fire truck enters the bottom of the vehicle 10, the spraying range of the first nozzle 111 is limited by the height of the chassis of the vehicle 10, and it is difficult to effectively cover the surrounding area of ​​the vehicle 10. The temperature of the vehicle 10 is very high during thermal runaway, and the high temperature formed by thermal radiation may affect the surrounding vehicles 10. The telescopic component 115 of this embodiment can extend toward the outside of the thermal runaway vehicle 10 under the control of the controller 150 after the vehicle body 100 reaches the bottom of the thermal runaway vehicle 10. The end of the telescopic component 115 can be directly extended to the outside of the thermal runaway vehicle 10, or the first nozzle 111 on the telescopic component 115 can be close to the edge of the thermal runaway vehicle 10. As long as the first nozzle 111 on the telescopic component 115 can spray a certain range on the outside of the vehicle 10, this embodiment does not limit the length of the telescopic component 115 extending outward. At the same time, the first nozzle of the first nozzle head 111 installed on the telescopic member 115 faces obliquely upward, so after the telescopic member 115 is extended, the first nozzle head 111 installed on the telescopic member 115 is as shown in FIG. Figure 3 As shown, the surrounding area of ​​the vehicle 10 can be covered, so that the fire truck can quickly and effectively reduce the thermal radiation temperature during thermal runaway and the temperature of a large amount of hot smoke at the bottom, effectively avoiding the spread of thermal runaway that may be caused to surrounding vehicles 10.

[0089] For example, the first nozzle of the first nozzle 111 mounted on the telescopic member 115 is oriented at an angle of 45° to the vertical direction, so as to further enhance the effect of cooling the surrounding smoke of the thermal runaway vehicle 10. Of course, this is only an example, and does not limit the direction of the first nozzle of the first nozzle 111.

[0090] It is understandable that the number and location of the telescopic components 115 can be set according to actual needs, and this embodiment does not limit them.

[0091] Exemplarily, the housing 130 is configured to be rectangular, and a telescopic component 115 is disposed on each of two sides in the length direction of the housing 130 . A first nozzle 111 is disposed at one end of the telescopic component 115 away from the housing 130 .

[0092] For example, Figure 5 As shown, four telescopic components 115 are arranged on the housing 130 , and the four telescopic components 115 are evenly arranged on the outside of the housing 130 . Meanwhile, on each telescopic component 115 , a plurality of first nozzles 111 can be sequentially arranged along the length direction of the telescopic component 115 .

[0093] It is understandable that the housing 130 may also be configured to be circular or in other shapes, as long as it can move freely at the bottom of the vehicle 10 , and this embodiment does not limit this.

[0094] Specifically, the spray device 110 also includes a first delivery pipe 113 and a second delivery pipe 114 that are perpendicular to each other. The first delivery pipe 113 and the second delivery pipe 114 are cross-arranged and connected to each other at the intersection. At least one of the first delivery pipe 113 and the second delivery pipe 114 is connected to the fire extinguishing agent interface 120. Four telescopic components 115 are correspondingly arranged at the ends of the first delivery pipe 113 and the second delivery pipe 114, and the first nozzles 111 on the four telescopic components 115 are correspondingly connected to the first delivery pipe 113 and the second delivery pipe 114, so that the water passing through the fire extinguishing agent interface 120 is delivered to the corresponding first nozzle 111 through the first delivery pipe 113 and the second delivery pipe 114 for spraying.

[0095] The first delivery pipe 113 and the second delivery pipe 114 can both be configured as hard pipes, and at least one of the first delivery pipe 113 and the second delivery pipe 114 is provided with at least one first nozzle 111 facing the first direction. That is, the first delivery pipe 113 and the second delivery pipe 114 can both be provided with a plurality of first nozzles 111 facing the top of the vehicle body 100, and these first nozzles 111 are used to spray the bottom of the vehicle 10 that is in thermal runaway.

[0096] Of course, the first nozzle 111 with the first nozzle facing the bottom of the vehicle body 100 can also be set on the first delivery pipe 113 and the second delivery pipe 114, so that water supply to all the first nozzles 111 can be achieved without setting other pipelines in the shell 130, simplifying the water supply structure.

[0097] It is understandable that, in order to protect the first nozzle 111 , the first nozzle end surfaces of the first nozzle 111 disposed on the first delivery pipe 113 and the second delivery pipe 114 are both flush with the outer edge of the housing 130 .

[0098] That is, due to the different chassis heights of vehicles of different sizes, the spraying range of the first nozzle 111 is also very different. Therefore, for vehicles of different sizes, the telescopic component 115 can be telescoped in different lengths and directions to achieve full coverage of the battery pack area at the bottom of the vehicle 10 and the outer edge of the vehicle 10. Of course, the telescopic component 115 is deployed only after the fire truck reaches the bottom of the accident vehicle 10 to avoid interference between the telescopic component 115 and the vehicle 10 or other components on the deck 20 during the movement of the vehicle body 100.

[0099] In some possible implementations, the telescopic component 115 may include a first hard tube, a second hard tube and a power assembly, the second hard tube is sleeved in the first hard tube, and the second hard tube is hollow inside, and a hose connected to the first delivery tube 113 or the second delivery tube 114 is arranged in the second hard tube, so that the hose is protected by the first hard tube and the second hard tube, and the hose has strong deformability and can also deform adaptively when the second hard tube moves relative to the first hard tube. The first nozzle 111 can be arranged at one end of the second hard tube that cannot be retracted into the first hard tube, and the power assembly can be a telescopic electric cylinder or a combination of a motor, a wire rope and a pulley, etc., as long as it can drive the second hard tube to move relative to the first hard tube.

[0100] The first hard tube can be installed in the shell 130. After the vehicle body 100 reaches the bottom of the thermal runaway vehicle 10, the controller 150 controls the power assembly to drive the second hard tube to extend, so that the first nozzle 111 can spray the outer edge of the thermal runaway vehicle 10. After the spraying is completed, the controller 150 controls the power assembly to drive the second hard tube back to its original position.

[0101] Of course, when it is necessary to set multiple first nozzles 111 on the telescopic part 115, the hose in the second hard tube can be fixed, and the first nozzle 111 connected to the hose can be installed at the corresponding position of the second hard tube. At the same time, the diameter of the first hard tube can be slightly larger so that when the second hard tube retracts into the first hard tube, it will not collide with the first nozzle 111.

[0102] It is understandable that the telescopic component 115 may also be configured as other structures, as long as it can be controlled by the controller 150 to be telescopic and drive the first nozzle 111 to move.

[0103] For some possible implementations, see Figure 2 As shown, the fire extinguishing agent also includes foam fire extinguishing agent, and the spraying device 110 also includes at least one second spray head 112, and the second spray head 112 is used to spray the foam fire extinguishing agent.

[0104] The foam fire extinguishing agent sprayed by the second nozzle 112 can quickly extinguish the open flame, form a suffocation area and a certain degree of isolation barrier, and prevent the fire from spreading.

[0105] It is understandable that when only one of the first nozzle 111 or the second nozzle 112 is on the vehicle body 100 , it only needs to be connected to the fire extinguishing agent interface 120 .

[0106] If the first nozzle 111 and the second nozzle 112 are provided on the vehicle body 100 at the same time, two fire extinguishing agent interfaces 120 can be provided, one connected to a storage tank storing foam fire extinguishing agent, and the other connected to a storage tank storing water, and the first nozzle 111 and the second nozzle 112 are connected to the corresponding fire extinguishing agent interfaces 120 through pipelines respectively.

[0107] Compared with separately setting the first nozzle 111 and the second nozzle 112, setting the first nozzle 111 and the second nozzle 112 at the same time can spray two different fire extinguishing agents according to the situation, which can better meet the fire extinguishing and cooling needs of the battery pack.

[0108] Specifically, if Figure 4 As shown, when the vehicle body 100 reaches under the thermally runaway vehicle 10, the second nozzle 112 can first spray foam fire extinguishing agent to extinguish the open flame and form a certain degree of isolation barrier, and then the second nozzle 112 is closed and the first nozzle 111 is opened. The first nozzle 111 sprays water mist for continuous cooling, so that the first nozzle 111 and the second nozzle 112 cooperate to achieve rapid fire extinguishing and continuous cooling.

[0109] In some possible implementations, when the first nozzle 111 and the second nozzle 112 are simultaneously provided on the vehicle body 100, only one fire extinguishing agent interface 120 may be provided to reduce the number of hoses to be dragged when the vehicle body 100 moves, thereby reducing the difficulty of moving the vehicle body 100. In this case, a reversing valve 180 may be provided on the vehicle body 100. The reversing valve 180 may be a three-way reversing valve. The three interfaces of the three-way reversing valve are respectively connected to the fire extinguishing agent interface 120, the first pipeline connected to the first nozzle 111, and the second pipeline connected to the second nozzle 112. The reversing valve 180 is connected to the controller 150. The controller 150 is also used to control the reversing valve 180 to switch between the first connection state and the second connection state.

[0110] It is understandable that the type of the reversing valve 180 can be selected according to the number of interfaces required. As long as the reversing valve 180 can be connected to the controller 150 and controlled by the controller 150, this embodiment does not limit it.

[0111] Among them, in the first connected state, the fire extinguishing agent interface 120 is connected to the first pipeline, and the fire extinguishing agent transported from the storage system enters the first nozzle 111 through the fire extinguishing agent interface 120 and the first pipeline. In the second connected state, the fire extinguishing agent interface 120 is connected to the second pipeline, and the fire extinguishing agent transported from the storage system enters the second nozzle 112 through the fire extinguishing agent interface 120 and the second pipeline, thereby realizing the alternating operation of the first nozzle 111 and the second nozzle 112 through the reversing valve 180.

[0112] Among them, in order to enable the foam fire extinguishing agent sprayed by the second nozzle 112 to form an isolation area around the thermally runaway vehicle 10 to prevent the fire from spreading, at least four second nozzles 112 can be provided, and the second nozzles are provided on the second nozzles 112. The second nozzle of one second nozzle 112 is directed toward directly above the vehicle body 100, the second nozzle of one second nozzle 112 is directed toward directly in front of the vehicle body 100, and the second nozzles of the two second nozzles 112 are respectively directed toward both sides of the vehicle body 100, that is, the foam fire extinguishing agent is sprayed from the top of the vehicle body 100, the front of the vehicle body 100, and both sides of the forward direction of the vehicle body 100 at the same time, so as to form a suffocation area and an isolation barrier around the thermally runaway vehicle 10 while extinguishing the fire of the battery pack.

[0113] It is understandable that the number of the second nozzles 112 can be greater, and the positions can be adjusted according to actual conditions, which is not limited in this embodiment.

[0114] Furthermore, a foam generator may be provided at the front end of the second nozzle of the second nozzle 112. When the foam fire extinguishing agent is sprayed, the foam generator may generate a large amount of foam, making it easier to extinguish the open fire. The foam generator is preferably a high-multiplicity foam generator. The high-multiplicity foam generator can generate a high foam multiple, which helps the foam fire extinguisher to quickly cover a large area and improve the rate of fire extinguishing and forming an isolation barrier. The high-multiplicity foam generator is a device well known to those skilled in the art, and will not be described in detail in this embodiment.

[0115] In some possible embodiments, the storage system may include a foam fire extinguishing agent tank and a fine water mist tank placed on the deck 20. Both the foam fire extinguishing agent tank and the fine water mist tank may be provided with solenoid valves to control whether to transport the foam fire extinguishing agent and water outward, and the solenoid valves may be communicatively connected to the controller 150, and may also be connected to the control system of the car transport ship.

[0116] Of course, the solenoid valve is directly connected to the controller 150 for communication, and the reaction delay is shorter. Specifically, after the vehicle body 100 reaches the bottom of the accident vehicle 10, the controller 150 first controls the solenoid valve of the foam fire extinguishing agent storage tank to open, and at the same time switches the reversing valve 180 to the second connected state, and the foam fire extinguishing agent is sprayed out through the second nozzle 112 through the second pipeline, and the second infrared camera 172 is used to determine whether the open fire is extinguished. After the open fire is extinguished, the controller 150 controls the solenoid valve of the foam fire extinguishing agent storage tank to close, controls the solenoid valve of the fine water mist storage tank to open, and controls the reversing valve 180 to switch to the first connected state, and water enters the first nozzle 111 through the first pipeline, so that the first nozzle 111 sprays high-pressure fine water mist, achieves continuous cooling, and forms a fine water mist barrier.

[0117] The foam fire extinguishing agent storage tank and the fine water mist storage tank can be connected to a hose via a three-way joint, and the fire extinguishing agent is transported to the fire extinguishing agent interface 120 via the hose.

[0118] The hose can be a high-pressure explosion-proof hose, through which the fire extinguishing agent is delivered to the fire extinguishing agent interface 120. The high-pressure explosion-proof hose can withstand high working pressure and is usually made of high-strength materials, such as high-strength fibers, etc. It adopts a multi-layer structure design, which can effectively prevent explosions caused by excessive pressure or external impact. At the same time, it can be applied to a variety of chemical media, has good corrosion resistance, and also has excellent high temperature resistance and flexibility, which is very suitable for use in the application environment of fire trucks. At the same time, the fire extinguishing agent interface 120 can be provided with a quick connector, which can be quickly connected with the high-pressure explosion-proof hose through the quick connector. In addition, since the moving path of the vehicle body 100 is long and needs to cover more vehicles 10, the overall length of the high-pressure explosion-proof hose is also long. At this time, an automatic hose reel can be provided to realize the automatic release and retraction of the high-pressure explosion-proof hose through the automatic hose reel. A dynamic hose reel generally includes a shell, a reel, a spring mechanism, a locking mechanism, a guide mechanism and other mechanisms. The reel is used to wind the conveying hose, the spring mechanism is used to provide power for automatic reeling, the locking mechanism allows the user to lock the conveying hose at any length, and the guide mechanism ensures that the conveying hose is evenly wound. The structure and principle of the automatic hose reel are well known to those skilled in the art, and will not be described in detail in this embodiment.

[0119] Of course, the hose may also be a pipe with other structures, as long as it is suitable for use in the current environment, and this embodiment does not limit it.

[0120] The vehicle body 100 will enter the bottom of the vehicle 10, causing the hose to be caught under the wheels of the vehicle 10, thereby hindering the movement of the vehicle body 100. For this, please refer to Figure 6 As shown, Figure 6The dotted line in the figure is the moving track of the fire truck. A plurality of roller devices 190 may be provided. The roller devices 190 are provided on the moving path of the vehicle body 100. The roller devices 190 are used to limit the moving path of the hose to prevent the hose from entering under the wheels of the vehicle.

[0121] Specifically, when parking the vehicle 10, the vehicle 10 will be arranged according to certain rules to facilitate parking and finding the vehicle 10. Figure 6 For example, when the vehicles 10 are neatly arranged in rows, the fire truck first moves left or right to the corresponding row of vehicles 10, and then enters the bottom of the corresponding row of vehicles 10. At this time, a roller device 190 can be installed on the outer side of the rear wheel of the last vehicle 10 in each row of vehicles 10. Through the roller device 190, when the vehicle body 100 enters the bottom of the corresponding row of vehicles 10, the movement path of the hose can be restricted to prevent the hose from entering under the wheels of the vehicle.

[0122] Among them, the roller device 190 may include at least one roller and a rotating shaft, the roller is rotatably connected to the rotating shaft, and the rotating shaft is used to connect with the deck 20. The rotating shaft is arranged perpendicular to the deck 20. When the vehicle body 100 moves around the roller to the bottom of the corresponding row of vehicles, the hose rolls in contact with the surface of the roller, and the hose is straight. Therefore, it is only necessary to limit the installation position of the roller to avoid the hose from being rolled under the wheels of the vehicle 10.

[0123] It can be understood that when the automatic hose reel is only arranged on one side of the deck 20, all the roller devices 190 can be set on the side of each row of vehicles 10 close to the automatic hose reel. Sometimes there are too many vehicles on one floor and multiple fire trucks may be equipped. In this case, an automatic hose reel may also be installed on the other side of the deck 20. In this case, roller devices 190 can be set on both sides of each row of vehicles 10.

[0124] Of course, in order to ensure the effectiveness of the roller device 190, the distance between the roller device 190 and the rear wheels of the last vehicle in each row is preferably greater than or equal to 10 cm. At the same time, the roller should also be at a certain distance from the side of the vehicle body, and can even be partially or completely located between the two rear wheels, as long as it does not block the moving path of the fire truck, to ensure that the hose can maintain a certain distance from the wheels of the vehicle 10 under the restriction of the roller to avoid entering under the wheels.

[0125] The present embodiment also provides a car transport ship, which includes multiple decks 20 and a control system. A cabin for parking vehicles 10 is formed between two adjacent decks 20. At least one fire truck in the above embodiment is arranged in each cabin. The controller 150 of the fire truck is communicatively connected with the control system. The controller 150 is used to receive the position information of the thermal runaway vehicle 10 transmitted by the control system, and control the body 100 of the fire truck to move to the bottom of the thermal runaway vehicle 10 to spray fire extinguishing agent according to the position information, thereby greatly improving the fire handling capability of the car transport ship.

[0126] Among them, the arrangement method and use principle of the fire truck on the deck 20 are described in detail in the above embodiments, and will not be repeated in this embodiment.

[0127] Finally, it should be noted that those skilled in the art will easily think of other embodiments of the present application after considering the specification and practicing the technical solutions disclosed herein. The present application is intended to cover any variations, uses or adaptations of the present application, which follow the general principles of the present application and include common knowledge or customary technical means in the art that are not disclosed in the present application, are not limited to the precise structures described above and shown in the drawings, and can be modified and changed in various ways without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
