Description

Technical Field

[0001] The present application relates to the technical field of fire extinguishing devices, and specifically discloses a fire extinguishing device and a sprinkler system for a new energy vehicle. Background Art

[0002] For new energy vehicles, in order to optimize the vehicle's weight distribution and ensure safety, the battery is usually installed under the chassis. This design helps to lower the vehicle's center of gravity and balance the load on the front and rear axles of the vehicle, thereby stabilizing the vehicle and improving its sports performance. In addition, since the battery is relatively heavy, the space under the chassis is relatively sufficient, which is suitable for installing large batteries.

[0003] The main cause of fires in new energy vehicles is battery failure. The structures of batteries for various types of electric vehicles are similar. Multiple battery cells are first packaged into battery modules, and then multiple battery modules are packaged into battery packs used in electric vehicles. When a battery cell is mechanically damaged or thermally damaged, an irreversible continuous temperature rise will occur. Once its temperature exceeds 150 degrees Celsius, it will cause thermal damage to the surrounding battery cells, and then cause thermal runaway accidents in each battery module and the entire battery pack. When fighting fires caused by new energy vehicle batteries, depending on the size of the battery and its charge state when the fire occurs, the duration of the thermal runaway accident may be as long as several hours.

[0004] During firefighting and rescue, rescue workers usually use coolants (such as liquid carbon dioxide) or dry powder sprays to extinguish and cool new energy vehicles from the outside of the vehicle to reduce the heat generated when the new energy vehicle catches fire. However, the burning point mainly comes from the battery, and the battery is located at the bottom of the new energy vehicle. Carbon dioxide or dry powder cannot be sprayed directly to the battery position, making fire extinguishing difficult and lasting for a long time.

[0005] Therefore, in view of this, the inventor provides a new energy vehicle fire extinguishing device to solve the above problems. Utility Model Content

[0006] One purpose of the utility model is to solve the problem that traditional fire extinguishing devices cannot quickly extinguish fires in batteries inside new energy vehicles; the second purpose is to propose a sprinkler system.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a new energy vehicle fire extinguishing device, including a seat body, a telescopic member, a puncture structure and a spray assembly, wherein the telescopic member is installed between the seat body and the puncture structure, and the telescopic member has an extended state and a retracted state, and is used to drive the puncture structure to extend or shorten;

[0008] The puncture structure includes a drill bit and a driving member, and the driving member is used to drive the drill bit to rotate;

[0009] The spray assembly is used for spraying cooling liquid toward the drill bit.

[0010] According to the above technical solution, the telescopic part is the part that provides power. When fire extinguishing is required, the telescopic part will receive the command and start working, driving the puncture structure to drill in. The piston of the telescopic part is pushed by air pressure, hydraulic pressure or electricity to generate enough force to make the drill penetrate the vehicle chassis. The drill bit has enough hardness and sharpness to penetrate the metal material of the chassis of the new energy vehicle. The drill bit is installed at the output end of the driving part. When the driving part is driven, the drill bit will quickly and accurately drill into the chassis and reach the battery or other parts that may catch fire. At the same time or after the drill bit penetrates the chassis, the coolant in the pipeline of the spray assembly will be transported to each nozzle. The nozzle design has a tendency to spray coolant toward the drill bit, ensuring that the coolant can be accurately and effectively sprayed into the battery and each fire point, reducing the temperature of the fire point and suppressing the spread of the fire, thereby achieving the effect of extinguishing the fire.

[0011] Furthermore, the telescopic member is one of a pneumatic cylinder, a hydraulic cylinder or an electric telescopic cylinder.

[0012] Furthermore, the puncture structure also includes a protective cover, which is covered on the outside of the driving member and is used to protect the driving member.

[0013] According to the above scheme, the protective cover can effectively prevent the body of the driving component from physical damage, such as dust, water vapor, corrosion, etc., thereby ensuring the normal operation of the driving component. At the same time, the protective cover can reduce external damage and extend the service life of the driving component.

[0014] Furthermore, a support member is provided between the telescopic member and the puncture structure, the support member is fixed on the top of the telescopic member, and the telescopic member can drive the support member to rise or fall.

[0015] According to the above technical solution, a support member is provided for installing the puncture structure, and the support member is fixed on the top of the telescopic member to facilitate connection with the puncture structure, thereby providing a stable support effect for the puncture structure.

[0016] Furthermore, a through hole is provided on the top of the protective cover, and a sealing member is provided in the through hole.

[0017] According to the above technical solution, a through hole is provided at the top of the protective cover to facilitate the passage of the output shaft of the motor, and a seal is provided to prevent external dust and liquid from entering the protective cover.

[0018] Furthermore, the driving member is a motor, the motor is fixedly installed inside the protective cover, and the output shaft of the motor extends out of the through hole and is fixedly connected to the drill bit.

[0019] Furthermore, when the telescopic member is in the retracted state, the distance from the bottom of the seat body to the top of the drill bit is a, wherein the value of a is not higher than 150 mm.

[0020] According to the above technical solution, the distance from the bottom of the seat to the top of the drill bit is no more than 150mm, which can be more easily adapted to various vehicle models, whether it is a sedan, SUV or other type of vehicle, and can be extended into the chassis of the vehicle, making it convenient for the drill bit to drill into the chassis quickly and accurately, directly reaching the battery or other parts that may catch fire, and has a wide range of applicability.

[0021] Furthermore, the spray assembly includes a pipeline and at least two spray heads, the pipeline surrounds the base body, and the pipeline is connected to each of the spray heads, and each of the spray heads has a tendency to spray coolant toward the drill bit.

[0022] Furthermore, the nozzle includes a connecting portion, a movable portion and a nozzle portion, the connecting portion, the movable portion and the nozzle portion are connected in sequence, and the connecting portion is fixed on the pipeline and communicated with the pipeline.

[0023] According to the above technical solution, the connecting part is used to be fixed on the pipe to facilitate the connection of the sprinkler head. The movable part can be adjusted to change the water outlet direction of the nozzle part. The nozzle part can be adjusted to spray water in different directions by adjusting the movable part, thereby achieving the effect of rapid fire extinguishing.

[0024] On the other hand, the utility model also proposes a sprinkler system, including a water supply pipe and a water supply pump, and also includes the new energy vehicle fire extinguishing device as mentioned above, and the new energy vehicle fire extinguishing device is connected to the water supply pump through the water supply pipe.

[0025] Beneficial effects of the utility model:

[0026] Due to the presence of the seat, telescopic parts and puncture structure, when the battery of the new energy vehicle catches fire, the piston of the telescopic part is pushed by air pressure, hydraulic pressure or electricity to generate enough force to make the drill penetrate the vehicle chassis; when the puncture structure works, the driving part drives the drill to rotate, and the drill has enough hardness and sharpness to penetrate the metal material of the chassis of the new energy vehicle. When the driving part is driven, the drill will quickly and accurately drill into the chassis and reach the battery or other parts that may catch fire. At the same time or after the drill penetrates the chassis of the car, coolant is injected into the pipeline, and the coolant in the pipeline will be transported to each nozzle. The nozzle is designed to spray the coolant toward the drill, ensuring that the coolant can be accurately and effectively sprayed into the battery and each fire point, reducing the temperature of the fire point and suppressing the spread of the fire, thereby achieving the effect of extinguishing the fire.

[0035] The following will refer to the accompanying drawings and preferred embodiments to illustrate the implementation of the utility model. Those skilled in the art can understand other advantages and effects of the utility model from the contents disclosed in this specification. The utility model can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the utility model. It should be understood that the preferred embodiments are only for illustrating the utility model, not for limiting the scope of protection of the utility model.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0037] This embodiment provides a new energy vehicle fire extinguishing device, such as Figure 1-Figure 6As shown, it includes a seat body 1, a telescopic member 2, a puncture structure 3 and a spray assembly, wherein the telescopic member 2 is installed between the seat body 1 and the puncture structure 3; wherein the bottom of the telescopic member 2 is fixed in the seat body 1, and the top of the telescopic member 2 is fixed to the puncture structure 3; the telescopic member 2 has an extended state and a retracted state, and is used to drive the puncture structure 3 to extend or shorten; wherein the puncture structure 3 includes a drill bit 31 and a driving member 32, and the driving member 32 is used to drive the drill bit 31 to rotate; as shown Figure 2 As shown, the drill bit 31 is a conical structure. Of course, it can be understood that the drill bit 31 can also have other structures besides the conical structure in this embodiment (such as a straight shank drill bit, a reaming drill bit, a center drill bit, a twist drill, and a flat drill, etc.).

[0038] When a battery of a new energy vehicle catches fire, the firefighters first determine the location of the battery in advance, and then use a push rod (not shown) to push the device under the vehicle. The piston of the telescopic member 2 is pushed by air pressure, hydraulic pressure or electricity to generate sufficient force to enable the drill bit 31 to penetrate the vehicle chassis; when the puncture structure 3 is working, the driving member 32 drives the drill bit 31 to rotate. The drill bit 31 has sufficient hardness and sharpness to penetrate the metal material of the chassis of the new energy vehicle. When the driving member 32 is driven, the drill bit 31 will quickly and accurately drill into the chassis and reach the battery or other parts that may catch fire.

[0039] The spray assembly includes a pipeline 6 and at least two spray heads 7 . The pipeline 6 surrounds the base body 1 , and the pipeline 6 is connected to each spray head 7 . Each spray head 7 has a tendency to spray coolant toward the drill bit 31 .

[0040] When the drill bit 31 is working, the coolant is controlled to be injected into the pipe 6, and the coolant in the pipe 6 will be transported to each nozzle 7. The nozzle 7 is designed to have a tendency to spray the coolant toward the drill bit 31, ensuring that the coolant can be accurately and effectively sprayed into the battery and each fire point, reducing the temperature of the fire point and suppressing the spread of the fire, thereby achieving the effect of extinguishing the fire.

[0041] In a possible implementation manner, the telescopic member 2 is one of a pneumatic cylinder, a hydraulic cylinder or an electric telescopic cylinder; in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the telescopic part 2 is a cylinder. As a power source, the cylinder has the characteristics of rapid response and can be quickly started when a fire occurs. Through its powerful driving force, the puncture structure 3 can quickly penetrate the chassis of the new energy vehicle, making it convenient for the coolant to be accurately sprayed to the fire point, timely controlling the fire, and realizing rapid and efficient fire extinguishing.

[0042] As a preferred embodiment, Figure 2As shown, the puncture structure 3 also includes a protective cover 33, which is coated on the outside of the driving member 32. The protective cover 33 can effectively prevent the body of the driving member 32 from being physically damaged, such as dust, water vapor, corrosion, etc., so as to ensure the normal operation of the driving member 32. At the same time, the protective cover 33 can reduce external damage and extend the service life of the driving member 32. A through hole is opened on the top of the protective cover 33, and a sealing member 331 is arranged in the through hole. The sealing member 331 is preferably a U-shaped water-blocking rubber ring. By setting a through hole on the top of the protective cover 33, the output shaft of the motor can pass through conveniently. The sealing member 331 is used to prevent external dust and liquid from entering the protective cover 33.

[0043] Furthermore, if Figure 1 and Figure 2 As shown, a support member 4 is further provided between the telescopic member 2 and the puncture structure 3, the support member 4 is fixed on the top of the telescopic member 2, and the telescopic member 2 can drive the support member 4 to rise or fall; as an exemplary embodiment, the telescopic member 2 is a circular structure; of course, it is understandable that the telescopic member 2 can also be a rectangular plate-shaped structure. The support member 4 is provided for installing the puncture structure 3, and the support member 4 is fixed on the top of the telescopic member 2 to facilitate the connection with the puncture structure 3, providing a stable support for the puncture structure 3.

[0044] As a preferred embodiment, Figure 2 As shown, the driving member 32 is a motor, which is fixedly installed inside the protective cover 33 , and the output shaft of the motor extends upwardly out of the through hole and is coaxially fixedly connected with the drill bit 31 .

[0045] Furthermore, if Figure 4 As shown, a rubber pad 5 is provided at the bottom of the seat body 1. By providing the rubber pad 5 at the bottom of the seat body 1, the rubber pad 5 has good elasticity and seismic isolation performance, which can effectively reduce the vibration and noise generated by the motor during operation, which can not only improve the stability and reliability of the motor, but also improve the working environment and reduce the impact of noise on the staff; during the operation of the motor, the motor may shift due to vibration, thereby affecting the stable operation of the drilling, and the friction coefficient of the rubber pad 5 is moderate, which can ensure that the motor maintains a stable position during operation and prevent it from shifting.

[0046] like Figure 4 As shown, when the telescopic member 2 is in the storage state, the distance from the bottom of the seat body 1 to the top of the drill bit 31 is a, wherein the value of a is not higher than 150 mm. By making the distance from the bottom of the seat body 1 to the top of the drill bit 31 not higher than 150 mm, it can be more easily adapted to various vehicle types, whether it is a sedan, SUV or other types of vehicles, and can be extended under the chassis of a new energy vehicle, so that the drill bit 31 can quickly and accurately drill into the chassis and directly reach the battery or other parts that may catch fire, and has a wide range of applicability.

[0047] like Figure 6 As shown, the nozzle 7 includes a connecting portion 71, a movable portion 72 and a nozzle portion 73, and the connecting portion 71, the movable portion 72 and the nozzle portion 73 are connected in sequence, and the connecting portion 71 is fixed on the pipe 6 and communicated with the pipe 6. Among them, the connecting portion 71 is used to be fixed on the pipe 6 and communicate with the pipe 6, which is convenient for the connection and installation of the nozzle 7, and the movable portion 72 can be adjusted to adjust the steering angle to change the water outlet direction of the nozzle portion 73. The movable portion 72 can be adjusted according to actual needs to adjust the nozzle portion 73 to spray water in different directions to achieve the effect of rapid fire extinguishing.

[0048] On the other hand, the utility model also proposes a sprinkler system, including a water supply pipe 8 and a water supply pump 9, and also includes the new energy vehicle fire extinguishing device as mentioned above, and the new energy vehicle fire extinguishing device is connected to the water supply pump 9 through the water supply pipe 8.

[0049] When the battery of the new energy vehicle catches fire, the firefighters connect the water supply pipe 8 to the water supply pump 9, and then connect the water supply pipe 8 to the interface of the pipe 6 in the fire extinguishing device, connect the cylinder and the motor to keep the cylinder and the motor working normally through control, and then the firefighters determine the position of the battery, and then use the push rod to push the device to the appropriate position under the vehicle, and then the firefighters stay away from the burning vehicle and operate the fire extinguishing device through the console at a distance. First, the motor is started, and the motor rotates to drive the drill bit 31 to work, and then the piston rod of the cylinder is controlled to be pushed upward to generate sufficient force to make the drill bit 31 penetrate the vehicle chassis; in the process of the cylinder being pushed upward, the water supply pump 9 is started to make it work normally, and the water supply pump 9 is passed into the pipeline 6 through the water supply pipe 8. The coolant in the pipeline 6 will be transported to each nozzle 7. The coolant in the nozzle 7 can be accurately and effectively sprayed to the inside of the battery and various fire points at the bottom of the new energy vehicle, thereby reducing the temperature of the fire point and suppressing the spread of the fire, thereby achieving the effect of rapid fire extinguishing; and when the drill bit 31 penetrates the bottom of the new energy vehicle, the coolant can enter the chassis to extinguish the fire and cool down the battery to prevent the battery from reigniting. The utility model has a compact structure and strong practicality.
