DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0030] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] At present, with the increasing demand for environmental protection and energy conservation around the world, the production and popularization of new energy electric vehicles have shown explosive growth. However, this rapid development trend has also brought many new technical challenges, especially in the centralized transportation of new energy electric vehicles. The potential safety hazards are particularly prominent. Among them, new energy electric vehicles are often transported by sea when transporting across borders. However, since the cabin environment is usually relatively closed and a large number of new energy vehicles are concentrated in a limited space, once a new energy vehicle catches fire, the fire can easily spread rapidly, endangering surrounding vehicles and even causing chain fires.

[0033] The fire characteristics of new energy electric vehicles are different from those of traditional fuel vehicles. Their fire points mostly come from the power battery system. Lithium-ion batteries, as the core components of new energy electric vehicles, are prone to thermal runaway when encountering external force impact, internal short circuit, overcharging or high temperature. Thermal runaway will not only cause the temperature inside the battery to rise rapidly, but may also cause the decomposition and combustion of battery materials, generating high-temperature flames and toxic gases. That is, the battery combustion process will release carbon monoxide, carbon dioxide, hydrogen, and highly corrosive hydrogen fluoride and other gases. These gases are not only highly flammable, but will also quickly fill the enclosed cabin space, significantly reducing visibility and increasing the difficulty of rescue operations.

[0034] In addition, the closed nature of the cabin further aggravates the complexity and danger of the fire. First, the closed space will cause the rapid accumulation of heat and toxic gases, making the time window for fire fighting extremely short. If the fire is not effectively controlled, the high temperature in the cabin may cause serious damage to the ship's structure and even endanger the overall safety of the ship. Secondly, the limited ventilation conditions in the closed environment make it impossible to quickly dissipate the smoke during the fire fighting process, which not only makes the fire-fighting operation difficult, but also poses a major threat to the lives of rescue workers.

[0035] Based on this, in a specific embodiment of the present disclosure, a fire prevention and control device for a new energy electric vehicle transportation process is provided, referring to Figures 1 to 8 As shown, the fire prevention and control device for the transportation process of the new energy electric vehicle includes: a storage tank 1, a fire detector 2, a nozzle 3, a prevention and control mechanism 4 and a controller 5. The prevention and control mechanism 4 has a storage cavity 403 for storing vehicles to be transported, and the storage cavity 403 is equipped with a nozzle 3 and a fire detector 2. The storage tank 1 is connected to the nozzle 3 by a connecting pipe 6 and a control valve 13 is installed on the connecting pipe 6. The controller 5 is electrically connected to the fire detector 2 and the control valve 13.

[0036] Through the above technical solution, a fire retardant is stored in the storage tank 1, and the fire retardant has the characteristic of high temperature resistance. The fire detector 2 and the nozzle 3 are both installed in the storage chamber 403, wherein the fire detector 2 can monitor the environmental parameters in the storage chamber 403 in real time, such as temperature, smoke concentration or flame signal, and the nozzle 3 is connected to the storage tank 1 through the connecting pipe 6, so that the fire retardant stored in the storage tank 1 can pass through the connecting pipe 6 and then be sprayed into the storage chamber 403 through the nozzle 3. Specifically, when the fire detector 2 detects a fire signal, for example: the temperature in the storage chamber 403 is too high or the smoke concentration in the storage chamber 403 increases, the fire detector 2 immediately transmits the signal to the controller 5. After receiving the signal from the fire detector 2, the controller 5 performs data analysis and determines whether to open the control valve 13. When the control valve 13 is opened, the fire retardant in the storage tank 1 passes through the connecting pipe 6. The flame retardant is transported to the nozzle 3, and then the flame retardant is sprayed into the storage chamber 403 through the nozzle 3, wherein the amount of the flame retardant sprayed into the storage chamber 403 must at least submerge the chassis of the new energy electric vehicle, so as to achieve the purpose of the flame retardant being able to completely cover the battery pack of the new energy electric vehicle. Specifically, the flame retardant can be a high-temperature resistant foam liquid, and the foam generated by the foam liquid has a burning time of more than 40 minutes at a high temperature of 800°C. The foam formed after the foam liquid is sprayed into the storage chamber 403 can submerge the burning vehicle, and the foam layer formed by the foam can effectively isolate the battery pack from contact with oxygen, cut off the combustion elements, and prevent the spread of fire as much as possible. At the same time, the fire detector 2 and the controller 5 can monitor the new energy electric vehicle in the storage chamber 403 in real time, so that relevant personnel can discover the fire in time at the early stage and take effective measures quickly to reduce the risk of fire spread.

[0037] Exemplarily, the high temperature resistant foam liquid can be selected from silicate-based composite foam, phosphorus-nitrogen expansion foam or perfluorohexanone foam.

[0038] Exemplarily, the fireproof cover can withstand high temperatures above 1200°C. The fireproof cover is made of high-temperature resistant materials. For example, the fireproof cover includes an outer layer, a middle layer, an inner layer and a sealing layer, wherein the outer layer is made of a ceramic fiber coating or a high-temperature resistant silicone rubber coated fabric; the middle layer is constructed as an aerogel cushion layer, which has the characteristics of extremely low thermal conductivity and light weight; the inner layer is made of fireproof inorganic cloth (glass fiber cloth, aramid cloth), which can protect the middle layer and minimize the wear of the middle layer; the sealing layer is made of rubber to ensure that the fireproof cover has good sealing properties.

[0039] Exemplarily, when a new energy electric vehicle located inside the storage chamber 403 catches fire, the high temperature and thick smoke generated by the fire can trigger the fire detector 2, and the fire detector 2 transmits relevant signals to the controller 5, thereby controlling the control valve 13 to open through the controller 5. After opening, the flame retardant in the storage tank can be sprayed out from the nozzle 3 after connecting the pipeline 6. At this time, the flame retardant sprayed into the storage chamber 403 quickly fills the storage chamber 403, and the foam generated by the flame retardant can submerge the burning vehicle, and the fire point is isolated from oxygen through the foam, thereby suppressing the spread of the fire source. At the same time, the fireproof cover can effectively isolate the flame in the storage chamber 403 to prevent the flame from affecting other surrounding vehicles.

[0040] In some embodiments, reference Figures 2 to 8 As shown, the prevention and control mechanism 4 includes a base 401, a mounting assembly 402, a fireproof cover and a fixing assembly, wherein the mounting assembly 402 is mounted on the base 401, and the base 401 can provide a stable support for the mounting assembly 402, the fireproof cover and the fixing assembly, so that the structure of the entire storage cavity 403 is more solid, and the vibration resistance of the prevention and control mechanism 4 during transportation is effectively improved;

[0041] At the same time, the fireproof cover is laid on the installation component 402, so that the fireproof cover, the base 401 and the installation component 402 together constitute a storage cavity 403. A fixed ring plate 7 is also provided on the side wall of the base 401. When the fireproof cover is laid on the installation component 402, the edge of the fireproof cover is located on the upper surface of the fixed ring plate 7. The fixing component is used to clamp and fix the edge of the fireproof cover to the fixed ring plate 7, so that the storage cavity 403 has good sealing performance, thereby limiting the spread of smoke and flames generated by the new energy electric vehicle when a fire occurs.

[0042] In some embodiments not shown in the figure, the fixing assembly is constructed as two clamping plates arranged between the fixing ring plates 7, and the two clamping plates are connected by a number of screws arranged at equal intervals. The two clamping plates are partially clamped between the fixing ring plates 7 and the fireproof cover. By screwing the nut so that the nut squeezes one of the clamping plates, the two clamping plates are forced to clamp the fireproof cover, thereby preventing the smoke and flames generated after the spontaneous combustion of the new energy electric vehicle from overflowing from the gap between the fixing ring plate 7 and the fireproof cover as much as possible.

[0043] In some embodiments, in order to ensure the airtightness between the fixed ring plate 7 and the fireproof cover, a rubber cushion layer may be provided on the fixed ring plate 7 to improve the sealing effect of the fixed assembly.

[0044] In some embodiments, before the fireproof cover is fixed by the fixing assembly, the edge of the fireproof cover can be bent downward to wrap around the fixing ring plate 7, so as to increase the contact area between the fixing ring plate 7 and the fireproof cover as much as possible, so that the two clamping plates can better clamp and seal the fireproof cover.

[0045] In some embodiments, the fixing component may also be made of fixing glue, and the fireproof cover is sealed and fixed on the fixing ring plate 7 by gluing.

[0046] In some embodiments, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the installation component 402 includes a first support frame 4021, a second support frame 4022 and a connecting rib 4023, wherein a rotating shaft 4024 for rotatably connecting the first support frame 4021 is provided on the side wall surface of the base 401, and the first support frame 4021 is rotatably connected to the base 401 through the rotating shaft 4024, and the first support frame 4021 is relatively arranged along the length direction of the base 401.

[0048] In some embodiments, reference Figure 7 and Figure 8As shown, in order to improve the stability of the structure, the first support frame 4021 and the second support frame 4022 can be connected by bolting, so as to enhance the connection strength between the first support frame 4021 and the second support frame 4022, that is, the second support frame 4022 is provided with two third mounting holes 40222 which are arranged opposite to each other along its length direction, and the first support frame 4021 is provided with a fourth mounting hole 40212 corresponding to the third mounting hole 40222, and the screw rod can pass through the third mounting hole 40222 and the fourth mounting hole 40212 in sequence, and then the first support frame 4021 and the second support frame 4022 are clamped and fixed by nuts.

[0049] In some embodiments, reference Figure 2 , Figure 7 and Figure 8 As shown, a mounting slot hole 40223 for mounting the fire detector 2 is provided between the two third mounting holes 40222, wherein the mounting slot hole 40223 is provided between the two third mounting holes 40222 to ensure that the fire detector 2 is located at the center position or key area of ​​the storage cavity 403, and can more comprehensively monitor the environmental parameters (such as temperature, smoke concentration, etc.) in the storage cavity 403, thereby improving the coverage of fire detection.

[0050] In some embodiments, reference Figure 4 and Figure 5As shown, a limiting member 8 for limiting the first support frame 4021 is also provided on the side wall of the base 401, and the limiting member 8 includes a fixed stop plate 801 and a limiting plate 802, and one end of the stop plate 801 away from the limiting plate 802 is connected to the side wall of the base 401, so that a receiving portion 803 for the first support frame 4021 is formed between the limiting plate 802 and the side wall of the base 401, that is, the stop plate 801 is fixedly connected to the side wall of the base 401 The first support frame 4021 has a first state and a second state, and the stop plate 801 is provided with a stop plate 802. A first limiting hole 8021 is provided for the limiting pin to pass through, and a second limiting hole 40213 corresponding to the limiting hole is provided on the first support frame 4021. When the first support frame 4021 is in the first state, part of the first support frame 4021 is located in the storage portion 803 and the first limiting hole 8021 and the second limiting hole 40213 are coaxially arranged. When in the first state, the limiting pin can be inserted into the first limiting hole 8021 and the second limiting hole 40213, so as to fix the first support frame 4021, thereby avoiding the displacement of the first support frame 4021 caused by vibration or external force during transportation, and improving the safety of the overall structure; when the first support frame 4021 is in the second state, the end of the first support frame 4021 away from the rotating shaft 4024 is placed on the upper surface of the fixing ring plate 7, that is, the first support frame 4021 in the second state is in a storage state, and the fixing ring plate 7 is used to store the first support frame 4021 at this time.

[0051] In some embodiments, the number of the second support frames 4022 is multiple, and the multiple second support frames 4022 are spaced apart along the width direction of the base 401. Figure 4 and Figure 7 As shown, the number of the through holes 40111 and the number of the fourth mounting holes 40212 are both multiple, which are used to install and fix multiple second support frames 4022.

[0052] In some embodiments, reference Figure 7 and Figure 8As shown, a locking hole 20224 is also provided on the second support frame 4022. When the first support frame 4021 is in the second state, the fixed ring plate 7 is used to accommodate the first support frame 4021 and the second support frame 4022. At this time, in order to enable the second support frame 4022 to be placed on the fixed ring plate 7 more stably, the second support frame 4022 can be fixed by a limit pin, that is, when the first support frame 4021 and the second support frame 4022 are both placed on the fixed ring plate 7, the first mounting hole 40211 and the locking hole 20224 can be coaxially arranged.

[0053] In some embodiments, in order to enable relevant personnel to provide more accurate fire warnings, the fire detectors 2 installed on the second support frame 4022 may be selected from a variety of types of fire detectors 2, including but not limited to image detectors, flame detectors, temperature detectors, smoke detectors, carbon monoxide gas concentration detectors, hydrogen concentration detectors, and VOC gas concentration detectors. Different types of fire detectors 2 may be installed on each second support frame 4022, wherein the fire detectors 2 are all existing technologies on the market, and the principles and functions of the fire detectors 2 are not elaborated here.

At the same time, a wiring hole 701 for passing the wire harness of the fire detector 2 is provided on the fixing ring plate 7, wherein the wiring groove 901 fixes the wire harness of the fire detector 2 in a specific path. The wire harness wear, looseness or breakage caused by vibration or friction is avoided, thereby improving the reliability of the fire detector 2 system. The wire arrangement hole 701 provides a standardized outlet for the wire harness of the fire detector 2, avoiding messy wiring and reducing problems such as short circuit and signal interference caused by entangled or loose wires. That is, the setting of the wire arrangement groove 901 and the wire arrangement hole 701 makes the wiring of the fire detector 2 more standardized, more intuitive and easy to operate, reducing the complexity of installation and debugging, and can also ensure smooth signal transmission and reduce the possibility of line failure.

[0055] In some embodiments, the second support frame 4022 provided with the reinforcing plate 9 can also enhance its own strength, making the overall structure more stable, thereby ensuring the operational stability of the fire detector 2.

The third mounting hole 40222 and the second mounting hole 40221 are both located at the bottom of the cable groove 901. When the bolts are installed, the head of the screw is located in the cable groove 901, and the inner wall surface of the cable groove 901 abuts against the head of the screw to limit its rotation, thereby achieving the purpose of facilitating the construction personnel to install the second support frame 4022 and improving the installation efficiency of the construction personnel.

[0057] Furthermore, in order to prevent toxic gases such as smoke generated by spontaneous combustion of new energy electric vehicles from overflowing from the wiring hole 701, the wiring hole 701 can be sealed with sealant after the wiring harness of the fire detector 2 is completed to prevent toxic gases such as smoke from overflowing into the cabin as much as possible.

[0058] In some embodiments, reference Figures 4 to 6 As shown, the base 401 includes a base 4011 and a cover plate 4012, the base 4011 has a cavity 40112, and the inner wall surface of the cavity 40112 is provided with a ring stage 10 for connecting the cover plate 4012, wherein the ring stage 10 may be provided with a threaded hole, and the cover plate 4012 is provided with a hole for screws to pass through, and the cover plate 4012 is fixed to the ring stage 10 by screws. At the same time, in order to improve the sealing between the cover plate 4012 and the ring stage 10, a screw thread may be formed on the upper surface of the ring stage 10 or on the lower surface of the cover plate 4012. A rubber cushion layer is provided on the surface; a first connecting pipe 40121 for connecting the nozzle 3 is provided on the cover plate 4012, and the end of the first connecting pipe 40121 away from the nozzle 3 extends into the cavity 40112 and is connected to the part of the connecting pipe 6 extending into the cavity 40112 through a hose, that is, when the controller 5 controls the control valve 13 on the connecting pipe 6 to open, the flame retardant stored in the storage tank 1 passes through the connecting pipe 6, the hose and the first connecting pipe 40121 in turn, and is sprayed into the storage cavity 403 through the nozzle 3.

[0059] Exemplarily, connecting the first connecting pipe 40121 and the connecting pipeline 6 through a hose can make the base 401 adapt to different pipeline layouts. For example, when multiple first connecting pipes 40121 are arranged on the cover plate 4012, the first connecting pipe 40121 and the connecting pipeline 6 can be connected by means of a three-way joint auxiliary hose.

[0060] In addition, the use of a hose to connect the first connecting pipe 40121 and the connecting pipeline 6 improves the flexibility of installation and subsequent maintenance, and reduces the difficulty of maintenance caused by fixed pipelines.

[0061] In some embodiments, reference Figures 4 to 6 As shown, the cover plate 4012 is further provided with a second connecting pipe 40122 for connecting the pressure relief valve 11, the second connecting pipe 40122 is used to connect the cavity 40112 with the storage cavity 403, and the pressure relief valve 11 is located in the inner cavity, and the base 4011 is further provided with a third connecting pipe 12 for connecting the pressure relief valve 11, and the pressure relief valve 11 connected to the third connecting pipe 12 is located outside the base 4011, that is, the pressure relief valve 11 is constructed as a one-way pressure relief valve 11, and the second connecting pipe 40122 and the third connecting pipe 12 are respectively connected to the pressure relief valve 11 located inside the cavity 40112 and the pressure relief valve 11 located outside the cavity 40112, thereby ensuring that the pressure management of the storage cavity 403 is more precise and effectively preventing the danger caused by excessive pressure.

[0062] Exemplarily, pressure relief valves 11 are installed on both the second connecting pipe 40122 and the third connecting pipe 12, which can accurately control the pressure value in the storage chamber 403, that is, the pressure relief valve 11 on the second connecting pipe 40122 is mainly responsible for the pressure regulation between the storage chamber 403 and the cavity 40112, and is suitable for rapid response to slight pressure fluctuations in the storage chamber 403; the pressure relief valve 11 on the third connecting pipe 12 is used as a subsequent reserve. When the pressure in the cavity 40112 is too high, the pressure relief valve 11 on the third connecting pipe 12 further releases the pressure to the external environment to avoid danger in the storage chamber 403.

[0063] The instructions for setting up the prevention and control mechanism 4 in the cabin are as follows: the base 401 is installed in the cabin and the vehicle is driven onto the base 401 with the help of a pad with a slope, and then the wheels are fixed to the base 401 with the help of a strapping tape. In order to facilitate the bundling of the strapping tape, a bundling hole can be opened on the base 401. After the bundling and fixing are completed, the personnel rotate the first support frame 4021 so that the first support frame 4021 is converted from the second state to the first state and the first support frame 4021 is fixed by a limit pin so that part of the first support frame 4021 is always located in the storage portion 803, and then the connecting ribs 4023 and the second support frame 4022 are installed. At the same time, the fire detector 2 needs to be installed when installing the second support frame 4022. After the installation is completed, the fireproof cover is covered on the installation component 402 and fixed by the fixing component to ensure the airtightness of the storage cavity 403.

[0064] It should be noted that in the present disclosure, due to the limited space in the cabin and the need to transport multiple vehicles, the vehicles need to be driven onto the base 401 before the first support frame 4021, the second support frame 4022 and the connecting rib 4023 are installed, and after the installation is completed, the fire cover is installed and fixed.
