Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to a mobile sprinkler fire extinguishing and cooling device for electric vehicles. Background Technology

[0002] The history of fire sprinkler systems spans nearly 300 years. As early as 1723 in England, wooden barrels, water, and some easily fusible components were assembled into a device capable of automatically spraying water to extinguish fires. With continuous technological advancements, perforated pipe sprinkler systems emerged in the early 19th century. However, this system suffered from the drawback of its small orifices being easily clogged by rust and debris. By the mid-19th century, automatic sprinkler heads appeared. Although early products were relatively bulky and lacked sensitivity, they laid the foundation for the development of modern firefighting technology.

[0003] In the West, the development of sprinkler systems has gone through several stages, including perforated pipe sprinkler systems, automatic sprinkler heads and wet sprinkler systems, dry valve and dry sprinkler systems, and improved linkage between automatic sprinkler heads and fire detection systems. In my country, since the emergence of sprinkler systems in the 1930s, they have also undergone more than 80 years of development and have achieved remarkable results in practical applications.

[0004] Fire sprinkler systems are categorized into different types based on product structure, application scenario, and working principle. Among these, based on product structure, they are mainly divided into open and closed types. Open sprinkler heads are generally used in deluge automatic fire extinguishing systems, while closed sprinkler heads are used in automatic sprinkler systems. Closed sprinkler heads are sprinkler heads with a release mechanism, which consists of heat-sensitive elements, seals, and other components. When a fire occurs, the glass bulb in the sprinkler head expands and ruptures due to heat, the sealing gasket loses its support, and pressurized water is sprayed out to extinguish the fire. Open sprinkler heads, on the other hand, do not have a release mechanism; the spray nozzle is open, and water pressure is directly sprayed through the sprinkler head.

[0005] Fire sprinkler systems, as an important type of fire-fighting equipment, play an irreplaceable role in protecting people's lives and property. However, in the case of new energy vehicles being transported by ship, battery fires may occur, threatening to ignite the fire. Crew members must then use the ship's fire suppression system to extinguish the fire. However, the bottom of new energy vehicles cannot be extinguished by fire sprinklers. The batteries of new energy vehicles are located at the bottom of the vehicle body, very low to the ground (<20cm). During firefighting, firefighters must be at close range, using fire hoses, which compromises their personal safety. If firefighting is attempted from a distance, the distance and angle limitations prevent the fire hoses from reaching the fire at the bottom of the vehicle, thus failing to achieve the desired extinguishing effect.

[0006] The prior art (publication number: CN207085117, publication date: 2018.03.13) discloses an automatic sprinkler fire extinguishing device for buses, including a water tank and a nitrogen tank installed at the rear of the bus. The nitrogen tank is connected to the water tank via a pressure reducing valve and a gas-water mixing valve. The gas-water mixing valve is connected to a handrail installed inside the bus. The handrail is made of steel pipe and has spray holes spaced apart on its side wall. The nitrogen tank is equipped with a solenoid valve, which is electrically connected to a release button via a controller. Pressing the button will activate the sprinkler fire extinguishing system inside the bus. The fixed installation method limits the fire extinguishing range and is not suitable for extinguishing fires at the battery of new energy vehicles.

[0007] The prior art (publication number: CN214436009U, publication date: 2021.10.22) discloses a mobile fire sprinkler extinguishing device, including: a fire truck body and a water pipe connected to the fire truck body; it also includes a moving component for moving the water pipe; and a fixing component for fixing the moving component. The fixing component is used to fasten the water pipe by driving the fixing block through the threaded rod. With the movement of the moving block, it is convenient for firefighters to quickly adjust the position of the water pipe. However, the spray range of the water pipe is limited. Even if it can be moved to the fire extinguishing position at the bottom of the new energy vehicle, the fire extinguishing speed is slow and the fire extinguishing range is small.

[0008] Therefore, it is essential to provide a mobile spray fire extinguishing and cooling device for electric vehicles that can be used to extinguish fires at the battery compartment of new energy vehicles, with a wide extinguishing range and fast extinguishing speed. Utility Model Content

The liquid outlet is located inside the fixed frame and communicates with the connecting pipe. Along the vertical direction, the liquid outlet and the distribution plate are positioned opposite each other. The distribution plate is umbrella-shaped and is formed by multiple trapezoidal baffles. There are liquid outlet gaps between adjacent trapezoidal baffles. Along the vertical direction, a guide head is also provided on the side of the distribution plate near the liquid outlet.

[0037] Example 1

[0038] This utility model provides a mobile sprinkler fire extinguishing and cooling device for electric vehicles, comprising: a main pipe 1, a longitudinal plate 4, mobile wheels 6, and a fire hose connection 5;

[0039] The main pipe 1 is a tubular pipe extending in the left-right direction x. A fire hose connection 5 is provided on one side of the main pipe 1, and an extension pipe 10 is provided on the other side of the main pipe 1. The extension pipe 10 includes an extension pipe 11 extending in the left-right direction x and a curved pipe 12 extending in the up-down direction z. In the up-down direction z, at least two nozzle groups are equally spaced on the side of the main pipe 1 away from the ground. The nozzle group includes two nozzles 3 arranged opposite each other in the front-back direction y. The extension direction of the nozzles 3 forms an angle β with the up-down direction y. The angle β is 20° to 40°. A sprinkler head 2 is provided in the middle between adjacent nozzle groups. A sprinkler head 2 is provided at the free end of the curved pipe 12.

[0040] The spray head 2 includes a connecting pipe 21, a liquid outlet 22, a fixing frame 23, and a diverter plate 24. The connecting pipe 21 is connected to the main pipe 1. The fixing frame 23 is located on the side of the connecting pipe 21 away from the main pipe 1. The fixing frame 23 is square-shaped. The liquid outlet 22 is located inside the fixing frame 23 and communicates with the connecting pipe 21. Along the vertical direction, the liquid outlet 22 is opposite to the diverter plate 24. The diverter plate 24 is umbrella-shaped and is formed by multiple trapezoidal baffles. There are liquid outlet gaps between adjacent trapezoidal baffles. Along the vertical direction, the diverter plate 24 is also provided with a guide head 25 on the side near the liquid outlet 22. The guide head 25 is an inverted cone.

[0041] The longitudinal plate 4 includes a left longitudinal plate 41 and a right longitudinal plate 42 arranged opposite each other in the left-right direction x. The left longitudinal plate 41 and the right longitudinal plate 42 are arranged perpendicular to the main pipe 1. The middle of the left longitudinal plate 41 and the right longitudinal plate 42 are fixedly connected to the side of the main pipe 1 away from the ground. In the left-right direction x, at least two spray heads 2 and two sets of nozzle groups 3 are provided between the left longitudinal plate 41 and the right longitudinal plate 42.

[0042] The movable wheel 6 includes a directional wheel 61 and a steering wheel 62. Along the front-to-back direction y, the directional wheel 61 is disposed opposite to both ends of the left longitudinal plate 41 or the right longitudinal plate 42, and along the front-to-back direction y, the steering wheel 62 is disposed opposite to both ends of the left longitudinal plate 41 or the right longitudinal plate 42.

[0043] The vertical distance from the top of the spray head 2 to the bottom of the moving wheel 6 in the up-down direction is 120mm-180mm;

[0044] The main pipe 1, the longitudinal plate 4, the spray head 2, and the nozzle 3 are made of stainless steel.

[0045] Specifically, the present invention provides a mobile sprinkler fire extinguishing and cooling device for electric vehicles, comprising: a main pipe 1, a longitudinal plate 4, mobile wheels 6, and a fire hose connection 5;

[0046] The main pipe 1 is a tubular structure extending in the left-right direction x. A fire hose connector 5 is provided on one side of the main pipe 1 for easy connection to existing fire-fighting equipment, improving its applicability. An extension pipe 10 is provided on the other side of the main pipe 1. The extension pipe 10 includes an extension pipe 11 extending in the left-right direction x and a curved pipe 12 extending in the up-down direction z. The extension pipe 11 and the curved pipe 12 are an integral structure. The length of the extension pipe 11 in the up-down direction z is the same as the diameter of the main pipe 1. At least two nozzle groups are equidistantly spaced on the side of the main pipe 1 away from the ground. Each nozzle group includes two nozzles arranged opposite each other in the front-back direction. The extension direction of the nozzles 3 forms an angle β with the up-down direction y, with the angle β ranging from 20° to 40°. A sprinkler head 2 is provided in the middle between adjacent nozzle groups. A sprinkler head 2 is provided at the free end of the curved pipe 12, effectively enhancing the spraying effect. During use, the spray range of the nozzles 3 and the spray range of the sprinkler head 2 intersect, forming a mist-like coverage, effectively increasing the fire extinguishing range.

[0047] It should be noted that the extension direction of nozzle 3 forms an angle β with the vertical direction y. The angle β can be 20°, 21°, 23°, 25°, 27°, 30°, 31°, 33°, 35°, 37°, 38°, and 40°. When the angle β < 20°, the liquid flow sprayed by nozzle 3 and the liquid flow sprayed by sprinkler head 2 will intersect more frequently, resulting in a smaller extinguishing range and affecting the extinguishing effect. When the angle β > 40°, the liquid flow sprayed by nozzle 3 and the liquid flow sprayed by sprinkler head 2 may not intersect, and the fire area cannot be fully covered during extinguishing. Therefore, when the angle is between 20° and 40°, the liquid flow sprayed by nozzle 3 and the liquid flow sprayed by sprinkler head 2 will intersect at a certain point, forming a mist-like coverage. This can fully cover the fire point without wasting resources, further improving the extinguishing effect.

[0048] It should be noted that fire hose couplings (Type 5) include many types. Among them, clamp-type couplings are couplings where the two ends of a fire hose are tightly fixed together with clamps, widely used for connecting fire trucks and fire hoses. This type of coupling has a simple structure, good tightness, and is easy to use, thus it is widely used in firefighting operations. Threaded couplings are a type of composite coupling, suitable for direct connections of fire hoses. This coupling contains eight gears, allowing for multiple rotations after engagement, has a long service life, a firm connection, and good leak-proof performance, and is widely used in firefighting. Hook-type couplings, also known as swivel couplings, are easy-to-disassemble couplings suitable for connecting fire hose-related pipelines. This coupling has a simple and flexible structure, allowing for quick connection and disassembly, facilitating firefighting work. Rotary couplings are mainly used for intermediate connections of fire hoses. The specially designed structure of this coupling ensures unobstructed liquid flow during use, making it convenient and reducing time and manpower costs in firefighting operations. Cast couplings are a special type of coupling, mainly used in complex situations involving fire hose connections. This connector is made using a die-casting process. It has a complex structure and a complicated manufacturing process, but it provides a strong connection and a long service life, enabling firefighters to work more safely and efficiently.

[0049] It should be noted that the fire hose connector 5 used in this embodiment is a DN50 fire hose connector 5, a connecting component used in fire protection systems. It is mainly used for connecting fire hoses, fire hydrants, and water guns to facilitate the delivery of fire extinguishing fluid. It features good sealing, quick and easy connection, and resistance to detachment. The DN50 fire hose connector 5 mainly consists of a body, a sealing ring seat, a rubber sealing ring, and a retaining ring. The sealing ring seat has grooves for securing the fire hose, ensuring a tight and stable connection. During connection, two interfaces of the same diameter are rotated 90° clockwise to form a single unit; the rubber sealing ring and retaining ring ensure a tight connection and prevent leakage.

[0050] It should be noted that sprinkler head 2 is connected to main pipe 1. In the event of a fire, the fire-fighting fluid in the hose will flow out to extinguish the fire. The sprinkler head continuously sprays fire-fighting fluid below the flames, which in most cases will completely extinguish the fire, or at least control the heat and limit the generation of toxic fumes.

[0051] It should be noted that, along the vertical direction z, at least two nozzle groups are equidistantly arranged on the side of the main pipe 1 away from the ground. Each nozzle group includes two nozzles 3 arranged opposite each other along the front-back direction y. The extension direction of the nozzles 3 forms an angle β with the vertical direction y, and the angle β is 20° to 40°. A sprinkler head 2 is arranged in the middle between adjacent nozzle groups. A sprinkler head 2 is provided at the free end of the curved pipe 12 so that the fire-fighting liquid sprayed from the nozzles 3 and the fire-fighting liquid sprayed from the sprinkler head 2 perpendicular to the main pipe 1 will have a certain intersection, which will effectively increase the fire-fighting range and enhance the fire-fighting effect.

[0052] The spray head 2 includes a connecting pipe 21, a liquid outlet 22, a fixing frame 23, and a diverter plate 24. The connecting pipe 21 is connected to the main pipe 1. The fixing frame 23 is located on the side of the connecting pipe 21 away from the main pipe 1. The fixing frame 23 is square-shaped. The liquid outlet 22 is located inside the fixing frame 23 and communicates with the connecting pipe 21. Along the vertical direction, the liquid outlet 22 is opposite to the diverter plate 24. The diverter plate 24 is umbrella-shaped and is formed by multiple trapezoidal baffles. There are liquid outlet gaps between adjacent trapezoidal baffles. Along the vertical direction, the diverter plate 24 is also provided with a guide head 25 on the side near the liquid outlet 22. The guide head 25 is an inverted cone.

[0053] It should be noted that the connecting pipe 21 is threaded and connected to the main pipe 1 for easy disassembly and replacement. The fixing frame 23 is located on the side of the connecting pipe 21 away from the main pipe 1. The fixing frame 23 is square-shaped. The liquid outlet 22 is located inside the fixing frame 23 and communicates with the connecting pipe 21. Along the vertical direction, the liquid outlet 22 is opposite to the diversion plate 24. The diversion plate 24 is umbrella-shaped and is formed by multiple trapezoidal baffles. There are liquid outlet gaps between adjacent trapezoidal baffles. Along the vertical direction, the diversion plate 24 is also provided with a guide head 25 on the side near the liquid outlet 22. The guide head 25 is an inverted cone. In the event of a fire, the fire-fighting liquid in the main pipe 1 can flow out from the liquid outlet 22. Under pressure, the liquid column flows towards the diversion plate 24. After passing through the guide head 25, the liquid column is dispersed and flows in various directions. It flows along the trapezoidal baffles to the area around the sprinkler head 2. Some of the fire-fighting liquid flows out through the liquid outlet gap, expanding the fire-fighting range.

[0054] The longitudinal plate 4 includes a left longitudinal plate 41 and a right longitudinal plate 42 arranged opposite each other in the left-right direction x. The left longitudinal plate 41 and the right longitudinal plate 42 are arranged perpendicular to the main pipe 1. The middle of the left longitudinal plate 41 and the right longitudinal plate 42 are fixedly connected to the side of the main pipe 1 away from the ground. In the left-right direction x, at least two spray heads 2 and two sets of nozzle groups 3 are provided between the left longitudinal plate 41 and the right longitudinal plate 42.

[0055] The movable wheel 6 includes a directional wheel 61 and a steering wheel 62. Along the front-to-back direction y, the directional wheel 61 is disposed opposite to both ends of the left longitudinal plate 41 or the right longitudinal plate 42, and along the front-to-back direction y, the steering wheel 62 is disposed opposite to both ends of the left longitudinal plate 41 or the right longitudinal plate 42.

[0056] It should be noted that the moving wheels 6 include directional wheels 61 and steering wheels 62. The directional wheels 61 and steering wheels 62 work together to make the fire extinguishing device move flexibly, reduce the difficulty of operation, and increase the practicality and applicability of the fire extinguishing device. The longitudinal plate 4 is located on the side of the main pipe 1 away from the ground. The moving wheels 6 on the side of the longitudinal plate 4 closer to the ground can also effectively save the space used by the fire extinguishing device, making it easier to move the fire extinguishing device to the bottom of the new energy vehicle, get as close as possible to the fire point, and enhance the fire extinguishing effect.

[0057] The vertical distance from the top of the spray head 2 to the bottom of the moving wheel 6 in the up-down direction is 120mm-180mm.

[0058] It should be noted that the vertical distance from the top of the spray head 2 to the bottom of the movable wheel 6 is the height of the mobile spray fire extinguishing and cooling device for electric vehicles provided by this utility model. Specifically, it can be 120mm, 123mm, 125mm, 126mm, 128mm, 130mm, 132mm, 136mm, 137mm, 140mm, 143mm, 145mm, 147mm, 149mm, 150mm, 153mm, 156mm, 158mm, 160mm, 162mm, 165mm, 168mm, 170mm, 174mm, 178mm, and 180mm. When the vertical distance between the top and bottom of the spray head 2 and the bottom of the moving wheel 6 is less than 120mm, the height of the mobile spray fire extinguishing and cooling device for electric vehicles is too low. During fire extinguishing, the spray range of the spray head 2 and the nozzle 3 may not be able to cover the fire point on the chassis of the new energy vehicle. When the vertical distance between the top of the spray head 2 and the bottom of the moving wheel 6 is greater than 180mm, the height of the mobile spray fire extinguishing and cooling device for electric vehicles is too high. It may not be able to be pushed into the bottom of the new energy vehicle, or it may be too close to the fire point, affecting the fire extinguishing effect. Therefore, when the vertical distance between the top of the spray head 2 and the bottom of the moving wheel 6 is 120mm-180mm, the mobile spray fire extinguishing and cooling device for electric vehicles can be pushed into the bottom of the new energy vehicle smoothly and can also play a good fire extinguishing role.

[0059] The main pipe 1, the longitudinal plate 4, the spray head 2, and the nozzle 3 are made of stainless steel.

[0060] It should be noted that stainless steel possesses excellent corrosion resistance, maintaining its appearance and performance in humid or harsh environments. This is crucial for fire extinguishing devices, which often operate in complex environments, including high temperatures, humidity, and corrosive gases. Stainless steel resists these corrosive factors, ensuring the long-term stable operation of the fire extinguishing device. Stainless steel also has high strength and impact resistance, capable of withstanding certain pressure and tension. This allows stainless steel fire extinguishing devices to maintain structural integrity and stability in emergencies such as fires, ensuring effective delivery and spraying of the extinguishing agent. Furthermore, stainless steel exhibits excellent high-temperature resistance, maintaining stable physical and chemical properties in high-temperature environments. This is particularly important for fire extinguishing devices used in high-temperature conditions, as high temperatures can cause other materials to deform, melt, or fail, while stainless steel ensures the normal operation of the fire extinguishing device under high temperatures. Finally, the smooth surface of stainless steel is easy to clean, allowing stainless steel fire extinguishing devices to maintain good hygiene during long-term use. Meanwhile, stainless steel also boasts high wear resistance, reducing wear and damage caused by friction and extending the service life of fire extinguishing devices. Its modern and aesthetically pleasing design enhances not only the practicality of the fire extinguishing device but also its overall environmental appeal. Furthermore, stainless steel is a fire-resistant material, strengthening the safety of the fire extinguishing device. In the event of a fire, stainless steel maintains structural stability and integrity, preventing secondary disasters caused by material combustion or deformation.

[0061] It is understood that the mobile sprinkler fire extinguishing and cooling device for electric vehicles provided by this utility model includes: a main pipe 1, a longitudinal plate 4, mobile wheels 6, and a fire hose connection 5; the main pipe 1 is a tubular structure extending in the left-right direction x, with a fire hose connection 5 on one side of the main pipe 1 and an extension pipe 10 on the other side of the main pipe 1. The extension pipe 10 includes an extension pipe 11 extending in the left-right direction x and a curved pipe 12 extending in the up-down direction z; the curved pipe 12 is equipped with sprinkler heads 2, and multiple sprinkler heads 2 are equidistantly arranged on the side of the main pipe 1 away from the ground in the up-down direction z. A nozzle group is arranged in the middle between adjacent sprinkler heads 2, and the nozzle group includes two nozzles 3 arranged opposite each other in the front-back direction y, with the extension direction of the nozzles 3 being the same as the extension direction of the main pipe 1. The longitudinal plates 4 and 42 are arranged at a certain angle of 30°. The longitudinal plates 4 include a left longitudinal plate 41 and a right longitudinal plate 42 arranged opposite each other in the left-right direction x. The middle of the left longitudinal plate 41 and the right longitudinal plate 42 is fixedly connected to the side of the main pipe 1 away from the ground to increase the stability of the fire extinguishing device. The moving wheels 6 include directional wheels 61 and steering wheels 62 to facilitate the movement of the fire extinguishing device. When in use, the staff uses the telescopic push-pull rod in conjunction with the moving wheels 6 to push the device to the chassis of the new energy vehicle. After connecting to the fire extinguishing fluid through the fire connector 5, the sprinkler head 2 and the nozzle group work simultaneously to form a confluence point, thereby generating splash and forming a mist coverage to fully cover the fire location. It can fully cover the battery position for cooling and fire extinguishing, with a wide coverage range, and can achieve rapid and effective fire extinguishing.

The angle β is 20° to 40°. A sprinkler head 2 is provided in the middle between adjacent nozzle groups. A sprinkler head 2 is provided at the free end of the curved pipe 12.

[0065] The spray head 2 includes a connecting pipe 21, a liquid outlet 22, a fixing frame 23, and a diverter plate 24. The connecting pipe 21 is connected to the main pipe 1. The fixing frame 23 is located on the side of the connecting pipe 21 away from the main pipe 1. The fixing frame 23 is square-shaped. The liquid outlet 22 is located inside the fixing frame 23 and communicates with the connecting pipe 21. Along the vertical direction, the liquid outlet 22 is opposite to the diverter plate 24. The diverter plate 24 is umbrella-shaped and is formed by multiple trapezoidal baffles. There are liquid outlet gaps between adjacent trapezoidal baffles. Along the vertical direction, the diverter plate 24 is also provided with a guide head 25 on the side near the liquid outlet 22. The guide head 25 is an inverted cone.

[0066] The spray angle of spray head 2 is 120°.

[0067] The spray angle of nozzle 3 is 40°.

[0068] Along the left-right direction x, the distance between adjacent spray heads 2 is 220mm-260mm.

[0069] The longitudinal plate 4 includes a left longitudinal plate 41 and a right longitudinal plate 42 arranged opposite each other in the left-right direction x. The left longitudinal plate 41 and the right longitudinal plate 42 are arranged perpendicular to the main pipe 1. The middle of the left longitudinal plate 41 and the right longitudinal plate 42 are fixedly connected to the side of the main pipe 1 away from the ground. In the left-right direction x, at least two spray heads 2 and two sets of nozzle groups 3 are provided between the left longitudinal plate 41 and the right longitudinal plate 42.

[0070] The movable wheel 6 includes a directional wheel 61 and a steering wheel 62. Along the front-to-back direction y, the directional wheel 61 is disposed opposite to both ends of the left longitudinal plate 41 or the right longitudinal plate 42, and along the front-to-back direction y, the steering wheel 62 is disposed opposite to both ends of the left longitudinal plate 41 or the right longitudinal plate 42.

[0071] The vertical distance from the top of the spray head 2 to the bottom of the moving wheel 6 in the up-down direction is 120mm-180mm;

[0072] The main pipe 1, the longitudinal plate 4, the spray head 2, and the nozzle 3 are made of stainless steel.

[0073] Specifically, the present invention provides a mobile sprinkler fire extinguishing and cooling device for electric vehicles, comprising: a main pipe 1, a longitudinal plate 4, mobile wheels 6, and a fire hose connection 5;

[0074] The main pipe 1 is a tubular structure extending in the left-right direction (x). A fire hose connector 5 is provided on one side of the main pipe 1 for easy connection to existing fire-fighting equipment, improving its applicability. An extension pipe 10 is provided on the other side of the main pipe 1. The extension pipe 10 includes an extension pipe 11 extending in the left-right direction (x) and a curved pipe 12 extending in the up-down direction (z). The extension pipe 11 and the curved pipe 12 are integrally formed. The length of the extension pipe 11 in the up-down direction (z) is the same as the diameter of the main pipe 1. At least two nozzle groups are equidistantly spaced on the side of the main pipe 1 away from the ground. Each nozzle group includes two nozzles arranged opposite each other in the front-back direction. The extension direction of the nozzles 3 forms an angle β with the up-down direction (y), with an angle β ranging from 20° to 40°. A sprinkler head 2 is positioned at the midpoint between adjacent nozzle groups. A sprinkler head 2 is located at the free end of the curved pipe 12. During use, the spray range of the nozzles 3 and the spray range of the sprinkler head 2 are... The water jets from nozzle 3 intersect with the fire-fighting liquid sprayed from sprinkler head 2, creating a mist-like coverage that effectively increases the fire extinguishing range. It should be noted that the extension direction of nozzle 3 forms an angle β with the vertical direction y. This angle β can be 20°, 21°, 23°, 25°, 27°, 30°, 31°, 33°, 35°, 37°, 38°, or 40°. When the angle β < 20°, the water jets from nozzle 3 intersect significantly with the fire-fighting liquid sprayed from sprinkler head 2, resulting in a smaller fire extinguishing range and affecting the extinguishing effect. When the angle β > 40°, the fire-fighting liquid sprayed from nozzle 3 and sprinkler head 2 may not intersect, failing to fully cover the fire area. Therefore, when the angle is between 20° and 40°, the fire-fighting liquid sprayed from nozzle 3 and sprinkler head 2 intersect at a certain point, forming a mist-like coverage that can fully cover the fire point without wasting resources, further enhancing the fire extinguishing effect.

[0075] It should be noted that fire hose couplings (5 types) include several types. Clamp-type couplings are couplings where the two ends of a fire hose are tightly secured together with clamps, widely used for connecting fire trucks and fire hoses. This type of coupling has a simple structure, good tightness, and is easy to use, thus it is widely used in firefighting operations. Threaded couplings are a type of composite coupling, suitable for direct connections of fire hoses. This coupling contains eight gears, allowing for multiple rotations after engagement, has a long service life, a strong connection, and good leak-proof performance, and is widely used in firefighting. Hook-type couplings, also known as swivel couplings, are easy-to-disassemble couplings suitable for connecting fire hoses and related pipelines. This coupling has a simple and flexible structure, allowing for quick connection and disassembly, facilitating firefighting work. Rotary couplings are mainly used for intermediate connections of fire hoses. The specially designed structure of this coupling ensures unobstructed liquid flow during use, making it convenient and reducing time and manpower costs in firefighting operations. Cast couplings are a special type of coupling, mainly used in complex situations involving fire hose connections. This connector is made using a die-casting process. It has a complex structure and a complicated manufacturing process, but it provides a strong connection and a long service life, enabling firefighters to work more safely and efficiently.

[0076] It should be noted that the fire hose connector 5 used in this embodiment is a DN50 fire hose connector 5, a connecting component used in fire protection systems, mainly for connecting fire hoses, fire hydrants, and water guns to facilitate the delivery of fire extinguishing fluid. It features good sealing, quick and easy connection, and resistance to detachment. The DN50 fire hose connector 5 mainly consists of a body, a sealing ring seat, a rubber sealing ring, and a retaining ring. The sealing ring seat has grooves for securing the fire hose, ensuring a tight and stable connection. During connection, two interfaces of the same diameter are rotated 90° clockwise to form a single unit; the rubber sealing ring and retaining ring ensure a tight connection and prevent leakage.

[0077] It should be noted that sprinkler head 2 mainly consists of a sprinkler, a fire extinguishing fluid plug, and a fire extinguishing fluid pipe. In the event of a fire, the fire extinguishing fluid in the pipe will flow out to extinguish the fire. The sprinkler head continuously sprays fire extinguishing fluid below the flames, which in most cases will completely extinguish the fire, or at least control the heat and limit the generation of toxic fumes.

[0078] It should be noted that, along the vertical direction z, multiple sprinkler heads 2 are equidistantly spaced on the side of the main pipe 1 away from the ground. Among them, a sprinkler head 2 is provided at the free end of the curved pipe 12. A nozzle group is provided in the middle between adjacent sprinkler heads 2. The nozzle group includes two nozzles 3 arranged opposite each other along the front-back direction y. The extension direction of the nozzle 3 forms a certain angle with the vertical direction, which is 20°-40°. The angle between the nozzle 3 and the vertical direction allows the fire-fighting liquid sprayed from the nozzle 3 to have a certain intersection with the fire-fighting liquid sprayed from the sprinkler head 2 perpendicular to the main pipe 1, effectively increasing the fire-fighting range and enhancing the fire-fighting effect.

[0079] It should be noted that the extension direction of nozzle 3 forms a certain angle with the vertical direction. The specific angle can be 20°, 21°, 23°, 25°, 27°, 30°, 31°, 33°, 35°, 37°, 38°, and 40°. When the angle is less than 20°, the fire-fighting liquid sprayed by nozzle 3 will have more overlap with the fire-fighting liquid sprayed by sprinkler head 2, resulting in a smaller fire extinguishing range and affecting the fire extinguishing effect. When the angle is greater than 40°, the water flow sprayed by nozzle 3 and the fire-fighting liquid sprayed by sprinkler head 2 may not overlap, and the fire area cannot be fully covered during fire extinguishing. Therefore, when the angle is between 20° and 40°, the fire-fighting liquid sprayed by nozzle 3 and the fire-fighting liquid sprayed by sprinkler head 2 will overlap to a certain extent, forming a mist-like coverage. This can fully cover the fire point without wasting resources, further improving the fire extinguishing effect.

[0080] The spray angle of spray head 2 is 110°-130°.

[0081] It should be noted that the 110°-130° spray angle allows sprinkler head 2 to cover a relatively large area, enabling rapid spraying of the fire source and surrounding area during a fire, effectively controlling the spread of the fire. This spray angle ensures that the fire-fighting liquid forms a uniform mist coverage during spraying, further improving fire extinguishing efficiency. The mist coverage can more effectively reduce the temperature of the fire source and isolate oxygen, thereby accelerating the extinguishing of the fire. A reasonable spray angle can reduce the waste of fire-fighting liquid resources and improve the economic efficiency of the fire protection system. The spray angle ensures fire extinguishing effectiveness while also considering resource conservation. Compared with other fire extinguishing methods, using fire sprinkler head 2 for fire extinguishing has less environmental pollution and ecological damage; a certain range of spray angles can minimize the impact on the surrounding environment while ensuring fire extinguishing effectiveness.

[0082] The spray angle of nozzle 3 is 30°-50°.

[0083] It should be noted that the nozzle assembly includes nozzles 3 symmetrically arranged along the front-to-back direction y. The extension direction of the nozzles 3 forms an angle of 20°-40° with the vertical direction z. The spray angle of the nozzles 3 is 3°-50°. The nozzle assembly is set between adjacent spray heads 2. In use, the nozzles 3 and the adjacent spray heads 2 can form a convergence point, convection to form a mist coverage, increase the fire extinguishing range, further enhance the fire extinguishing effect, and cover the fire point in all directions.

[0084] Along the left-right direction x, the distance between adjacent spray heads 2 is 220mm-260mm.

[0085] Optionally, the spacing between adjacent sprinkler heads 2 can be 220mm, 223mm, 225mm, 226mm, 228mm, 230mm, 231mm, 233mm, 236mm, 240mm, 243mm, 244mm, 246mm, 248mm, 250mm, 251mm, 253mm, 255mm, 258mm, 259mm, and 260mm. When the spacing between adjacent sprinkler heads 2 is less than 220mm, the spacing is too small, the spray range of the sprinkler head 2 is small, and it is easy to waste resources. When the spacing between adjacent sprinkler heads 2 is greater than 260mm, the spacing is too large, the spray range is small during fire extinguishing, and it is easy to miss the fire points. Reduced fire extinguishing effect; When the distance between adjacent sprinkler heads 2 is 220mm-260mm, the distance is appropriate, and the sprinkler heads 2 with a spray angle of 120° and the nozzles 3 with a spray angle of 40° are distributed alternately, which can achieve a better fire extinguishing effect.

[0086] The spray head 2 includes a connecting pipe 21, a liquid outlet 22, a fixing frame 23, and a diverter plate 24. The connecting pipe 21 is connected to the main pipe 1. The fixing frame 23 is located on the side of the connecting pipe 21 away from the main pipe 1. The fixing frame 23 is square-shaped. The liquid outlet 22 is located inside the fixing frame 23 and communicates with the connecting pipe 21. Along the vertical direction, the liquid outlet 22 is opposite to the diverter plate 24. The diverter plate 24 is umbrella-shaped and is formed by multiple trapezoidal baffles. There are liquid outlet gaps between adjacent trapezoidal baffles. Along the vertical direction, the diverter plate 24 is also provided with a guide head 25 on the side near the liquid outlet 22. The guide head 25 is an inverted cone.

[0087] It should be noted that the connecting pipe 21 is threaded and connected to the main pipe 1 for easy disassembly and replacement. The fixing frame 23 is located on the side of the connecting pipe 21 away from the main pipe 1. The fixing frame 23 is square-shaped. The liquid outlet 22 is located inside the fixing frame 23 and communicates with the connecting pipe 21. Along the vertical direction, the liquid outlet 22 is opposite to the diversion plate 24. The diversion plate 24 is umbrella-shaped and is formed by multiple trapezoidal baffles. There are liquid outlet gaps between adjacent trapezoidal baffles. Along the vertical direction, the diversion plate 24 is also provided with a guide head 25 on the side near the liquid outlet 22. The guide head 25 is an inverted cone. In the event of a fire, water or other fire extinguishing liquid in the main pipe 1 can flow out from the liquid outlet 22. Under pressure, the liquid flows towards the diversion plate 24. After passing through the guide head 25, the liquid column is dispersed and flows in various directions. It flows along the trapezoidal baffles to the area around the sprinkler head 2. Some liquid flows out through the liquid outlet gaps, expanding the fire extinguishing range.

[0088] The longitudinal plate 4 includes a left longitudinal plate 41 and a right longitudinal plate 42 arranged opposite each other in the left-right direction x. The left longitudinal plate 41 and the right longitudinal plate 42 are arranged perpendicular to the main pipe 1. The middle of the left longitudinal plate 41 and the right longitudinal plate 42 are fixedly connected to the side of the main pipe 1 away from the ground. In the left-right direction x, at least two spray heads 2 and two sets of nozzle groups 3 are provided between the left longitudinal plate 41 and the right longitudinal plate 42.

[0089] The movable wheel 6 includes a directional wheel 61 and a steering wheel 62. Along the front-to-back direction y, the directional wheel 61 is disposed opposite to both ends of the left longitudinal plate 41 or the right longitudinal plate 42, and along the front-to-back direction y, the steering wheel 62 is disposed opposite to both ends of the left longitudinal plate 41 or the right longitudinal plate 42.

[0090] It should be noted that the moving wheels 6 include directional wheels 61 and steering wheels 62. The directional wheels 61 and steering wheels 62 work together to make the fire extinguishing device move flexibly, reduce the difficulty of operation, and increase the practicality and applicability of the fire extinguishing device. The longitudinal plate 4 is located on the side of the main pipe 1 away from the ground. The moving wheels 6 on the side of the longitudinal plate 4 closer to the ground can also effectively save the space used by the fire extinguishing device, making it easier to move the fire extinguishing device to the bottom of the new energy vehicle, get as close as possible to the fire point, and enhance the fire extinguishing effect.

[0091] The vertical distance from the top of the spray head 2 to the bottom of the moving wheel 6 in the up-down direction is 120mm-180mm.

[0092] It should be noted that the vertical distance from the top of the spray head 2 to the bottom of the movable wheel 6 is the height of the mobile spray fire extinguishing and cooling device for electric vehicles provided by this utility model. Specifically, it can be 120mm, 123mm, 125mm, 126mm, 128mm, 130mm, 132mm, 136mm, 137mm, 140mm, 143mm, 145mm, 147mm, 149mm, 150mm, 153mm, 156mm, 158mm, 160mm, 162mm, 165mm, 168mm, 170mm, 174mm, 178mm, and 180mm. When the vertical distance between the top and bottom of the spray head 2 and the bottom of the moving wheel 6 is less than 120mm, the height of the mobile spray fire extinguishing and cooling device for electric vehicles is too low. During fire extinguishing, the spray range of the spray head 2 and the nozzle 3 may not be able to cover the fire point on the chassis of the new energy vehicle. When the vertical distance between the top of the spray head 2 and the bottom of the moving wheel 6 is greater than 180mm, the height of the mobile spray fire extinguishing and cooling device for electric vehicles is too high. It may not be able to be pushed into the bottom of the new energy vehicle, or the distance from the fire point may be too great, affecting the fire extinguishing effect. Therefore, when the vertical distance between the top of the spray head 2 and the bottom of the moving wheel 6 is 120mm-180mm, the mobile spray fire extinguishing and cooling device for electric vehicles can be pushed into the bottom of the new energy vehicle smoothly and can also play a good fire extinguishing role.

[0093] The main pipe 1, the longitudinal plate 4, the spray head 2, and the nozzle 3 are made of stainless steel.

[0094] It's important to note that stainless steel possesses excellent corrosion resistance, maintaining its appearance and performance in humid or harsh environments. This is crucial for fire extinguishing systems, which often operate in complex environments, including high temperatures, humidity, and corrosive gases. Stainless steel resists these corrosive factors, ensuring the long-term stable operation of the system. Furthermore, stainless steel has high strength and impact resistance, capable of withstanding pressure and tension. This allows stainless steel fire extinguishing systems to maintain structural integrity and stability in emergencies such as fires, ensuring effective delivery and spraying of the extinguishing agent. Stainless steel also exhibits excellent high-temperature resistance, maintaining stable physical and chemical properties even at high temperatures. This is particularly important for fire extinguishing systems used in high-temperature environments, as high temperatures can cause other materials to deform, melt, or fail, while stainless steel ensures the normal operation of the system under these conditions. Finally, the smooth and easy-to-clean surface of stainless steel allows it to maintain good hygiene during long-term use. Meanwhile, stainless steel also boasts high wear resistance, reducing wear and damage caused by friction and extending the service life of fire extinguishing devices. Its modern and aesthetically pleasing design enhances not only the practicality of the fire extinguishing device but also its overall environmental appeal. Furthermore, stainless steel is a fire-resistant material, strengthening the safety of the fire extinguishing device. In the event of a fire, stainless steel maintains structural stability and integrity, preventing secondary disasters caused by material combustion or deformation.

A certain included angle, the included angle is 30°; the longitudinal plate 4 includes a left longitudinal plate 41 and a right longitudinal plate 42 arranged opposite each other in the left and right direction x. The middle of the left longitudinal plate 41 and the right longitudinal plate 42 is fixedly connected to the side of the main pipe 1 away from the ground to increase the stability of the fire extinguishing device. The moving wheel 6 includes a directional wheel 61 and a steering wheel 62 to facilitate the movement of the fire extinguishing device. When in use, the staff uses the telescopic push-pull rod in conjunction with the moving wheel 6 to push the device to the chassis of the new energy vehicle. After connecting to the fire extinguishing fluid through the fire connector 5, the sprinkler head 2 and the nozzle group work simultaneously to form a spray intersection point, thereby producing splash and forming a mist coverage to fully cover the fire position. It can fully cover the battery position for cooling and fire extinguishing. The coverage range is relatively wide and can achieve rapid and effective fire extinguishing. It is understood that the mobile sprinkler fire extinguishing and cooling device for electric vehicles provided by this utility model includes: a main pipe, a longitudinal plate, mobile wheels, and a fire hose connector; the main pipe is a tubular structure extending in the left-right direction, with a fire hose connector on one side and an extension pipe on the other side, the extension pipe including an extension pipe extending in the left-right direction and a curved pipe extending in the up-down direction; the curved pipe is equipped with sprinkler heads, and at least two sets of nozzle groups are equidistantly arranged on the side of the main pipe away from the ground in the up-down direction, each nozzle group including two nozzles arranged opposite each other in the front-back direction, the extension direction of the nozzles forming an angle β with the up-down direction, the angle β being 20° to 40°, and a sprinkler head is arranged in the middle between adjacent nozzle groups, wherein the curved pipe A sprinkler head is provided at the free end; the longitudinal plates include a left longitudinal plate and a right longitudinal plate arranged opposite each other in the left-right direction.

It can provide full coverage cooling and fire extinguishing for the battery location, with a wide coverage range, and can achieve rapid and effective fire extinguishing.

[0096] Example 3

[0097] This embodiment further explains the connection method between the main pipe 1 and the longitudinal plate 4 based on embodiment 2: the fixed connection is welding.

[0098] It should be noted that welding connections do not require drilling holes in the steel, saving labor and time, and do not reduce the cross-sectional area of ​​the material, thus making full use of the material. Components of any shape can be directly connected, generally without the need for auxiliary parts. The connection structure is simple, the force transmission path is short, and it has a wide range of applications. Welding connections do not weaken the cross-section of the component, thus saving steel. There are many types of welding methods, which can be automated, improving processing efficiency. Welded connections have good airtightness and watertightness, high structural rigidity, and good overall integrity. Welded connections have high structural rigidity and good overall integrity, and can withstand greater external forces.

[0099] Example 4

[0100] This embodiment further explains the connection method between the moving wheel 6 and the main pipe 1 based on embodiment 3: the connection method between the directional wheel 61 and the left longitudinal plate 41 or the right longitudinal plate 42 is screw connection, and the connection method between the steering wheel 62 and the left longitudinal plate 41 or the right longitudinal plate 42 is screw connection.

[0101] It's worth noting that screw connections have a relatively simple structure. Typically, you only need to drill a hole in the parts to be connected, insert the screw, and tighten it. This structure makes installation and disassembly very convenient, suitable for various occasions. Screw connections do not require complex tools or skills; simple tightening and loosening operations complete the connection and disassembly. This characteristic makes maintenance and component replacement very easy. Because screw connections do not require complex tools or skills, installation and disassembly costs are reduced. Furthermore, the relatively simple materials and manufacturing processes of screws also contribute to lower overall costs. Screw connections come in various types, such as ordinary screws, self-tapping screws, and wood screws, suitable for different materials and connection requirements. Each type of screw has its specific application scenarios, capable of meeting diverse connection needs.

[0102] Example 5

[0103] This embodiment describes the connection method of the fire extinguishing device in detail based on embodiment 4: it also includes a fireproof fire hose, one end of which is connected to the fire connector 5 of the main pipe 1, and the fireproof fire hose is made of fireproof and flame-retardant material and high temperature and pressure resistant material.

[0104] It should be noted that fire-resistant fire hoses are flexible, expandable pipes primarily used in fire extinguishing systems to transport extinguishing media such as water, foam, and dry powder. They are crucial devices connecting the fire source and the fire itself, allowing for the rapid delivery of extinguishing media to the fire scene for effective fire suppression. In use, one end of the fire hose is connected to the fire hose connector 5 of the main pipe 1, and the other end is connected to existing fire-fighting equipment via the fire hose connector 5, enabling long-distance fire suppression.

[0105] It should be noted that the outer layer of fire-resistant fire hoses can be made of fire-retardant materials. These materials have extremely high oxygen index values, making the fire hoses less prone to combustion when exposed to a fire source. Even if the outer layer is ignited, it can quickly self-extinguish, effectively preventing the spread of flames. This characteristic buys more time for personnel evacuation and firefighting efforts, reducing the damage caused by fires. Fire hoses may come into contact with high-temperature environments, even flames, during use. Fire-retardant materials maintain stable performance at high temperatures and will not deform or be damaged by heat. For example, some fire-resistant, high-temperature resistant silicone sleeves can provide continuous protection up to several hundred degrees Celsius and withstand higher molten splash temperatures. This excellent high-temperature resistance ensures the reliability and safety of the fire hose under extreme conditions. Fire-retardant materials typically have high compressive and impact resistance, allowing the fire hoses to withstand certain pressures and impacts without cracking or deforming. This characteristic protects internal wiring and cables from damage, ensuring the stability and durability of the fire hose in complex environments. Fire hoses may come into contact with various chemicals during use, such as hydraulic oil, lubricating oil, and fuels. Fire-retardant materials possess excellent acid and alkali resistance, are non-corrosive, and contain no plasticizers, odors, or attract insects and rodents. These characteristics ensure the stability and safety of fire hoses in harsh environments. In fires, incomplete combustion produces large amounts of toxic fumes, a major cause of fire-related deaths. Current flame-retardant materials simultaneously achieve flame retardancy, smoke suppression, and toxicity reduction, without generating highly toxic or unusual combustion products. When the outer layer of a fire hose is made of fire-retardant material, even in the event of a fire, the generation of toxic fumes can be effectively reduced, minimizing casualties.

[0106] High-temperature and pressure-resistant synthetic materials are generally used for the inner layer of fire-resistant hoses, enabling them to maintain stable performance in high-temperature, high-pressure, and corrosive environments. This ensures the normal operation of the fire protection system. These materials can withstand high temperatures and are not easily deformed or damaged. In high-temperature environments such as fire scenes, the inner layer of the fire-resistant hose maintains structural stability, ensuring the smooth delivery of extinguishing agents. They also possess high strength, capable of withstanding the impact of high-pressure liquid flows. During fire protection system operation, the inner layer of the fire-resistant hose can withstand significant pressure, ensuring the fire-fighting fluid can reach the fire scene smoothly. Furthermore, these materials exhibit excellent resistance to various chemical substances. Corrosion resistance: The inner layer of fire-resistant hoses may come into contact with various extinguishing media and chemicals, and these materials ensure that the hoses will not be damaged by corrosion. High-temperature and pressure-resistant synthetic materials maintain high strength while also possessing a certain degree of flexibility, allowing fire-resistant hoses to maintain flexibility during installation and use, facilitating layout and connection. The inner layer of fire-resistant hoses made of high-temperature and pressure-resistant synthetic materials can maintain stable performance over a long period of time, helping to reduce the frequency of replacement and maintenance, thereby reducing the operating costs of the fire protection system. High-temperature and pressure-resistant synthetic materials are not prone to the growth of bacteria and microorganisms, helping to keep the fire-fighting fluid clean and hygienic, ensuring that the fire-fighting effect is not affected by fire-fighting fluid issues during the fire-fighting process.
