Description

Technical Field

[0001] This utility model relates to the field of fire isolation equipment technology, and in particular to a vehicle fire isolation cover. Background Technology

[0002] With the continuous growth of motor vehicle ownership, the frequency of vehicle fire accidents is increasing year by year. Whether it is a private car, commercial vehicle, or electric bicycle, fires can occur during driving or parking due to reasons such as electrical faults, oil leaks, or battery thermal runaway. Vehicle fires are characterized by rapid spread and strong high-temperature radiation. If not controlled in time, they will not only destroy the vehicle itself, but may also ignite nearby parked vehicles, buildings, or green belts, causing large-scale secondary disasters and posing a serious threat to people's lives and property.

[0003] In real life, most of the physical isolation devices used for vehicle fire extinguishing are insufficient. They cannot form a relatively closed space through the combination of stable structure and fireproof materials, making it difficult to effectively block the heat and flame transfer between the burning vehicle and the external environment, which can easily lead to secondary disasters. Therefore, a vehicle fire isolation cover is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a vehicle fire isolation cover, which aims to solve the problem of insufficient physical isolation effect of existing vehicle fire extinguishing isolation devices.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a vehicle fire isolation cover, comprising: The frame and the fireproof cover fitted on the outside of the frame. The frame is composed of three U-shaped rods that are hinged to each other. The frame is movably connected by the mounting base and unfolds in a fan shape. The fire extinguishing component, located inside the frame, is used to extinguish fires by spraying water onto vehicles enclosed by the fireproof cover.

[0006] As a further description of the above technical solution: Metal wheels are located around the bottom of the frame.

[0007] As a further description of the above technical solution: Straps are installed around the inside of the fireproof cover, close to the frame.

[0008] As a further description of the above technical solution: The fire extinguishing assembly includes a sprinkler pipe positioned around the frame relative to the inside of the fireproof cover, sprinkler heads fixedly installed around the top and bottom of the sprinkler pipe, and an external connecting pipe connected to one side of the bottom of the sprinkler pipe via a connecting pipe. The external connecting pipe is used to connect to a fire hydrant.

[0009] As a further description of the above technical solution: Straps are also provided around the outside of the sprinkler pipe, close to the frame.

[0010] As a further description of the above technical solution: The fire extinguishing assembly includes nozzles fixedly installed inward around the top and bottom of the frame. The frame is hollow inside. Two flexible hoses for connecting to the inside of the frame are fixedly connected around the inner side of the bottom of the frame. External water pipes for connecting to fire hydrants are fixedly connected to the outside of the flexible hoses.

[0011] As a further description of the above technical solution: The fireproof cover is made of heat-insulating and fire-resistant soft material.

[0012] As a further description of the above technical solution: The U-shaped rod located in the middle includes a U-shaped rod body and two sets of adjusting sleeves. The U-shaped rod body is located at the upper center of the frame. The two sets of adjusting sleeves are respectively sleeved on the front and rear ends of the bottom of the U-shaped rod body. The bottom end of the adjusting sleeve is hinged to the other two U-shaped rods. The U-shaped rod body and the adjusting sleeves are detachably connected by a limiting member.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the combination of the frame and the fireproof cover can tightly cover the vehicle to form a relatively closed space, effectively blocking the heat and flame transfer between the burning vehicle and the external environment, preventing the fire from spreading to surrounding vehicles or buildings, and reducing the risk of secondary disasters. The fire extinguishing components are integrated inside the frame, and while the isolation cover is deployed to complete physical isolation, it can be quickly connected to the fire hydrant to start fire extinguishing.

[0014] 2. In this utility model, the fire extinguishing components can increase the overall weight of the isolation cover after water is supplied. Combined with the stable support of the bottom metal wheels, this solves the problem of floating and shifting caused by air pressure changes when a fire occurs in traditional isolation equipment, ensuring that the isolation effect is continuous and effective. At the same time, the height of the U-shaped rod located in the middle of the frame can be adjusted by the adjustable sleeve and screw hole, so that the isolation cover can be adapted to vehicles of different heights.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Reference Figure 1 This utility model provides an embodiment of a vehicle fire isolation cover, comprising: a frame 1 and a fireproof cover 2 fitted over the outside of the frame 1. The fireproof cover 2 is made of heat-insulating and fire-resistant soft material, such as aramid fiber, Nomex fiber, high-silica fireproof cloth, etc., which has the characteristics of general fibers, such as softness, elasticity, and a certain tensile strength. It can be further processed into various products such as paper, thread, rope, belt, blanket, and felt. It also has non-combustible, high temperature resistance (550~1700℃), and corrosion resistance properties that general fibers do not have. The frame 1 is movably connected by mounting bases 3 and unfolds in a fan shape. Both the frame 1 and the mounting bases 3 can be made of metal materials. The frame 1 has three U-shaped rods, and each U-shaped rod and the corresponding mounting base 3 are connected by a pin pivot. When unfolded, it can support a frame that can cover the vehicle. Through the fireproof cover 2 on it, a relatively closed space can be formed to isolate the burning vehicle. When folded, the volume is greatly reduced compared to unfolded, making it easy to store.

[0019] Metal wheels 4 are provided around the bottom of the frame 1 to facilitate dragging the isolation cover and placing it in the correct position. Straps 5 are also provided around the inside of the fireproof cover 2, close to the frame 1. Straps 5 are used to fix the fireproof cover 2 to the frame 1. Straps 5 can also be Velcro.

[0020] It should be noted that the overall dimensions of the isolation enclosures are roughly divided into two types: car isolation enclosures and electric bicycle isolation enclosures. The car isolation enclosure is approximately 5.6 meters long, 2.4 meters wide, and 2.2 meters high, suitable for private cars with 7 seats or less; the electric bicycle isolation enclosure is approximately 2.4 meters long, 1 meter wide, and 1.5 meters high. Additionally, their dimensions can also be customized to meet specific requirements.

[0021] Working principle: The operator selects the corresponding standard size fire shield according to the type of vehicle on fire. If the vehicle model is special, a customized size version can be used. Through the pin pivot connection structure between the frame 1 and the mounting base 3, the originally folded frame 1 is opened halfway upward to form a frame structure that can be fitted on the outside of the vehicle. The process can be operated by a single person without additional tools. At the same time, the metal wheels 4 under the frame 1 are pushed to move the half-opened fire shield to directly above the vehicle on fire. After adjusting the position, the frame 1 is fully opened to form a semi-circular cross section, which covers the vehicle on fire, so that the fire shield 2 can completely cover the vehicle.

[0022] After the frame 1 is unfolded, the fireproof cover 2, which is fitted on the outside, naturally forms a relatively closed space. Its high temperature resistance can block the heat transfer between the flame and the external environment, preventing the fire from spreading to surrounding vehicles or buildings. The straps 5 inside the fireproof cover 2, which are close to the frame 1, automatically fit and fix it, preventing the fireproof cover from shifting under airflow disturbance, while ensuring the airtightness of the closed space and reducing the leakage of smoke and high temperature gas.

[0023] After the fire is extinguished, untie strap 5 and fold the three U-shaped rods together using the pin pivot structure. At this time, the volume of the isolation cover is greatly reduced compared to the unfolded state, making it easy to transport to fire trucks or warehouses for storage, waiting for the next use. Example

[0024] Reference Figure 2 The difference between Embodiment 2 and Embodiment 1 is that a fire extinguishing component is added on the basis of Embodiment 1. The fire extinguishing component is used to suffocate or cool down the burning vehicle covered by the fireproof cover 2.

[0025] The fire extinguishing assembly includes a sprinkler pipe 61 positioned around the frame 1 relative to the interior of the fireproof cover 2. The sprinkler pipe 61 serves two purposes: first, by injecting water into the sprinkler pipe 61 from the outside, it increases the weight of the fireproof cover, preventing the fireproof cover from rising due to air pressure and affecting the fireproofing effect. Sprinkler heads 62 are fixedly installed around the top and bottom of the sprinkler pipe 61, allowing water to enter the sprinkler pipe 61 and be sprayed onto the burning vehicle inside the fireproof cover through the sprinkler heads 62 for fire extinguishing. An external connecting pipe 64 is connected to one side of the bottom of the sprinkler pipe 61 via a connecting pipe 63. The external connecting pipe 64 is used to connect to a fire hydrant. A strap 5 is provided around the outside of the sprinkler pipe 61 close to the frame 1 to secure the sprinkler pipe 61.

[0026] The beneficial effects of Example 2: Based on Example 1, the outer pipe 64 is connected to the fire hydrant through the connecting pipe 63, and the water flows into the sprinkler pipe 61 set around the outside of the frame 1. On the one hand, the sprinkler pipe 61 after being filled with water increases the overall weight of the isolation cover, preventing the isolation cover from floating due to the rise in air pressure when a fire starts; on the other hand, the water flows through the sprinkler heads 62 installed inward from the top and bottom of the sprinkler pipe 61, spraying in a three-dimensional ring onto the vehicle surface, quickly cooling and extinguishing the fire. The outer pipe 64 is fixed to the frame 1 with the straps 5 to prevent shaking after water is supplied. After the fire is extinguished, the isolation cover can be disassembled and stored. Example

[0027] Reference Figure 3 The difference between Embodiment 3 and Embodiment 2 lies in the replacement of a different fire extinguishing component. The fire extinguishing component includes nozzles 72 fixedly installed inward around the top and bottom of the frame 1. The frame 1 is hollow inside, and the water flowing into the frame 1 can be sprayed out through the nozzles 72. Two hoses 71 for connecting to the inside of the frame 1 are fixedly connected around the inner side of the bottom of the frame 1. The three U-shaped rods can be connected through the hoses 71. An external water pipe 73 for connecting to a fire hydrant is fixedly connected to the outside of the hoses 71, so that after the external water pipe 73 is connected to the fire hydrant, the water flow can reach the inside of the frame 1. In addition to the function of spraying water to extinguish fire, it can also increase the overall weight of the isolation cover and prevent it from floating.

[0028] The beneficial effects of Example 3: Based on Example 1, the external water pipe 73 is connected to the fire hydrant, and the water flows into the hollow frame 1 through the hose 71. The three U-shaped rods are connected through the hose 71 to ensure that the water flow is evenly distributed. The water flow increases the weight of the frame 1 and strengthens the stability of the isolation cover. On the other hand, it sprays the fire evenly onto the burning vehicle through the nozzles 72 installed inward from the top and bottom of the frame 1 to achieve the fire extinguishing function. The operation process is simplified. After the fire is extinguished, the fire hydrant is closed, the external water pipe 73 is disconnected, and the residual water in the fire extinguishing component is released. After the fire is extinguished, the isolation cover can be disassembled and stored. Example

[0029] Reference Figure 4 , Figure 5The difference between Embodiment 4 and Embodiment 1 lies in the replacement of the U-shaped rod structure located in the middle of the frame 1. The U-shaped rod in the middle position includes a U-shaped rod body 11 and two sets of adjusting sleeves 12. The U-shaped rod body 11 is located at the upper center of the frame 1. The two sets of adjusting sleeves 12 are respectively sleeved on the front and rear ends of the bottom of the U-shaped rod body 11. The bottom end of the adjusting sleeve 12 is hinged to the other two U-shaped rods. The U-shaped rod body 11 can move vertically within the adjusting sleeves 12, and thus can move vertically relative to the adjusting sleeves 12, allowing the U-shaped rod in the middle position to... The height is adjustable. The U-shaped rod 11 and the adjusting sleeve 12 are detachably connected by a limiting component, which includes a bolt 113. Several sets of screw holes 111 are arranged in a straight line on the inner walls of both sides of the U-shaped rod 11, while several through holes 112 are arranged in a straight line on the adjusting sleeve 12. The screw holes 111 at different positions correspond to different adjustment heights of the U-shaped rod 11. After the U-shaped rod 11 is adjusted to the required height relative to the adjusting sleeve 12, the bolt 113 can be threaded through the through holes 112 and connected to the corresponding screw holes 111 to fix the U-shaped rod 11.

[0030] The beneficial effects of Example 4: Based on Example 1, if the vehicle height is high, the height of the U-shaped rod in the middle of the frame 1 can be adjusted in advance, and the U-shaped rod 11 can be pulled up so that the U-shaped rod 11 moves upward in a straight line within the adjusting sleeve 12. After reaching the required height, the U-shaped rod 11 is fixed by using bolts 113 through the through hole 112 and screwed into the corresponding height screw hole 111, thereby enabling the frame 1 to cover vehicles of different heights.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
