Abstract
Description
Technical Field
[0001] This utility model relates to fire-fighting equipment, and more specifically, to a foldable foam fire-extinguishing enclosure device for new energy vehicles. Background Technology
[0002] Unlike traditional gasoline-powered vehicles, when a new energy vehicle spontaneously combusts, the dry powder sprayed from a traditional fire extinguisher, once covering the lithium battery, not only fails to extinguish the fire but also causes the battery's temperature to rise rapidly due to the inability to dissipate heat, accelerating the spontaneous combustion. While water can lower the battery's temperature and slow the chemical reaction within it, gradually extinguishing the flames, the reaction speed will accelerate again once water is stopped, leading to reignition. Therefore, foam-type fire extinguishing agents are currently widely used, as they simultaneously cool the battery and isolate it from external oxygen. To achieve faster fire suppression, firefighters typically use fencing to enclose the burning new energy vehicle and then spray foam extinguishing agent into the enclosed area to submerge the lithium battery portion. However, firefighting is a time-sensitive emergency, and current fencing devices are generally modular, requiring on-site installation and connection, a time-consuming process. Furthermore, after the fencing device is installed, it is usually operated by multiple firefighters working together, one person pulling at one point, to quickly move the fencing device closer to and surround the new energy vehicle. However, due to the emergency operating environment, the personnel may be under considerable stress, inevitably leading to excessive pulling. The manual positioning method is prone to being pulled, causing deviations in the positioned location, and sometimes even requiring adjustments to the fencing after it has been surrounded. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a foldable foam fire extinguishing enclosure device for new energy vehicles. It does not require the enclosure to be installed and can be used directly by unfolding, which greatly improves work efficiency. After use, it can be folded for storage, making it very convenient to operate.

Detailed Implementation
[0017] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention. See Figures 1-11This utility model discloses a foldable foam fire extinguishing enclosure device for new energy vehicles, comprising a first enclosure 2, a rear enclosure 5, and multiple first enclosures 3 and second enclosures 4. The multiple first enclosures 3 and second enclosures 4 are sequentially hinged together to form the enclosure body. In this embodiment, a first bushing 19 and a second bushing 20 are respectively installed on the connecting sides of the two hinged enclosures. For example, one end of the first enclosure 3 is provided with a first bushing 19, and the other end with a second bushing 20; while one end of the second enclosure 4 connected to the first enclosure 3 is provided with a second bushing 20, and the other end with a first bushing 19. During installation, after the first bushing 19 of the first enclosure 3 and the second bushing 20 of the second enclosure 4 are coaxially aligned, a rotating shaft is inserted, and then pins are inserted at both ends of the rotating shaft to position it, thereby achieving the hinged connection between the enclosures.
[0018] In this embodiment, the first enclosure 2 and the last enclosure 5 are respectively installed at both ends of the enclosure body. Unlike the first enclosure 3 and the second enclosure 4, the first enclosure 2 and the last enclosure 5 are provided with a connecting structure at their joint, so as to realize the detachable connection of the first and last enclosures, thereby achieving the purpose of quickly assembling to form a rapid enclosure for the new energy vehicle 1, and quickly disassembling it.
[0019] Specifically, the connection structure includes a first thickened portion 7 at the end of the first enclosure 2 and a second thickened portion 8 at the end of the tail enclosure 5. The end of the first thickened portion 7 is provided with an insert 10, and the end of the second thickened portion 8 is provided with a stepped groove 11 that matches the insert 10. Strong magnets 9 are embedded in both the insert 10 and the bottom of the stepped groove 11. Through the cooperation of the insert 10 and the stepped groove 11, the gap between the first and tail enclosures during connection can be effectively reduced, thereby reducing the leakage of fire extinguishing foam at this point. Furthermore, the stepped groove 11 improves the stability of the first and tail enclosures at the connection point, preventing displacement of the thickened portion. The connection between the first and tail enclosures is achieved through adsorption by the strong magnets 9, ensuring quick assembly and disassembly. To ensure the reliability of the connection, a longer overall length of the strong magnets 9 can be used to increase the adsorption area on both sides of the connection point, thereby ensuring that the connection strength requirements are met.
[0020] Generally, foam fire extinguishing enclosure devices for new energy vehicles are typically rectangular, which not only surrounds the new energy vehicle but also minimizes the number of enclosures used. Therefore, in this embodiment, three positioning structures are provided in the main body of the enclosure as positioning points 6, so that the main body of the enclosure can surround the new energy vehicle 1 using these three positioning points 6. The positioning structures are located at the hinge points of the first enclosure 3 and the second enclosure 4, corresponding to the positions of the positioning points 6.
[0021] Specifically, the positioning structure includes an extended rotating shaft 14 and a positioning seat 15. The positioning seat 15 is installed below one of the fence sections and has an inner cavity. The extended rotating shaft 14 passes through the first bushing 19, the second bushing 20, and the inner cavity in sequence. A limiting plate 16 is installed on the extended rotating shaft 14 located in the inner cavity. A sealing cap 18 is screwed to the bottom of the inner cavity. A spring 17 is installed in the inner cavity between the limiting plate 16 and the sealing cap 18. Through the action of the spring 17, the limiting plate 16 is always located at the top of the inner cavity in the initial state. At this time, the top of the extended rotating shaft 14 is higher than the top of the fence, and the bottom is located above the bottom of the fence with a certain gap. When positioning is required, downward pressure is applied to the extended rotating shaft 14, causing the spring 17 to compress. When the bottom of the extended rotating shaft 14 contacts the ground and has a certain pressure, the extended rotating shaft 14 can be used to position the fence body at that point, thereby facilitating the pulling of the rest of the fence body.
[0022] Preferably, the top of the extended shaft 14 is screwed with an operating part to facilitate pressing the extended shaft 14. In addition, the lower end of the extended shaft 14 is provided with a pointed structure, which reduces the contact area between the extended shaft 14 and the ground, thereby effectively improving the reliability of positioning under the same applied pressure.
[0023] In this example, each of the first enclosure 2, the last enclosure 5, the first enclosure 3, and the second enclosure 4 has a protrusion 12 on one side, with the protrusions 12 of adjacent enclosures arranged back-to-back. The thickness of the protrusion 12 is the same as the thickness of the enclosure, and its overall shape is a curved surface, smaller at the front and larger at the back, narrower at the top and wider at the bottom. Its interior is a cavity into which the protrusions of adjacent enclosures can be inserted, allowing adjacent enclosures to fold smoothly. This design not only improves the stability of the enclosure device after installation but also facilitates the folding and storage of the enclosures.
[0024] In addition, the first enclosure 2, the last enclosure 5, the first enclosure 3 and the second enclosure 4 are all provided with arc-shaped recesses 13, and the arc-shaped recesses 13 of two adjacent enclosures are arranged opposite to each other, which can further improve the stability of the enclosure device after it is installed.
[0025] Preferably, a flexible foam curtain 21 is fixed between the two hinged enclosures to prevent fire extinguishing foam from seeping out from the hinge joint. Specifically, the flexible foam curtain 21 is made of high-temperature resistant rubber sheet, and its two ends are fixed to the two enclosures by hot melt adhesive. Its length is designed to accommodate the folding of the enclosures in different directions.
[0026] The working principle of this utility model is as follows: When in use, the folded enclosure device is unfolded. Then, the positioning point 6 closest to the first enclosure 2 is used as the target point. It is first moved to a corner of the new energy vehicle 1. Then, the operating part above the extended rotating shaft 14 on the positioning point 6 is pressed, causing the bottom of the extended rotating shaft 14 to touch the ground and establish positioning at that point. Next, the operators at the other points quickly pull the enclosure device to wrap around the new energy vehicle 1, so that the other two positioning points 6 are in place and positioned sequentially. Finally, when the tail enclosure 5 is pulled to the docking position of the first enclosure 2, the insert 10 is inserted into the step groove 11, and after ensuring stable adhesion, the installation of the enclosure device is complete. Testing shows that the enclosure device can complete the entire process of unfolding and wrapping around the new energy vehicle 1 in as little as 10 seconds.
[0027] After use, separate the joints of the beginning and end of the enclosure, and then refer to... Figure 1 Flip the first enclosure 2 towards the new energy vehicle 1 and fold it together with the first enclosure 3; then flip the first enclosure 3 away from the new energy vehicle 1 and fold it together with the second enclosure 4; repeat this process to complete the folding and storage of the enclosure device.
[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
