Technical Field
[0001] This utility model relates to the technical field of water storage tanks for preventing reignition of fires in new energy vehicles, and in particular to the enclosure used for water storage tanks for preventing reignition of fires in new energy vehicles. Background Technology
[0002] At accident scenes or during workshop testing of new energy vehicles, anti-reignition water tanks are required. The purpose of these tanks is to enclose the vehicle to prevent reignition and allow for water filling. Existing technologies for anti-reignition water tank enclosures for new energy vehicles mainly fall into two categories:
[0003] The first category involves prefabricating a single, rectangular or circular pool using flexible materials (such as inflatable soft structures). The disadvantages are: the strength of the flexible material enclosure is insufficient, requiring additional rigid materials for support; otherwise, the pool is easily crushed by the water pressure inside, losing its water-holding capacity. In particular, when the pool is approximately rectangular, the longer side bears greater water pressure, necessitating more support structures. When the pool is approximately circular, since vehicles are generally rectangular, the circular pool requires a larger diameter (using the longer side as the diameter), resulting in low water utilization.
[0004] Moreover, in the existing technology, the bottom of the inflatable water tank is sealed as one piece (i.e., the enclosure and the bottom are an integral structure to prevent water leakage). When using it, it is very difficult and inconvenient to lift a new energy vehicle that is burning or at risk of reignition into the water tank.
[0005] The second category involves using rigid materials (such as L-shaped flood barriers or other shaped rigid barriers) to assemble a rectangular or circular pool. The disadvantages are: it requires multiple rigid material barriers, resulting in a large volume and weight, which is inconvenient to carry due to limited storage space in fire trucks; furthermore, assembling several rigid material barriers on-site is cumbersome and time-consuming, hindering rescue efforts.
[0006] In particular, when these rigid material enclosures come into contact with the ground, gaps will appear between them, causing serious water leakage in the pool (the leakage is especially serious when the ground is uneven, and water needs to be continuously added to maintain the water level in the pool to meet the usage requirements).
[0007] Due to the aforementioned deficiencies, the following technical problems need to be solved for those skilled in the art:
[0008] 1. Existing soft material water storage tanks have defects such as insufficient lateral compressive strength and a tendency to tip over.
[0009] 2. How to improve the water leakage at the bottom of the fence, especially in environments with uneven ground, and how to improve the serious water leakage problem of the fence;
[0010] 3. Fire trucks have limited carrying space. How can we minimize their size and weight after storage while ensuring their effectiveness?
[0011] 4. How to simplify the steps of assembling the fencing to facilitate firefighters' use and operation in emergency situations and improve work efficiency.
[0012] Overcoming the aforementioned shortcomings is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0013] In view of the above-mentioned defects of the prior art, the present invention provides a fence for a water storage tank for preventing reignition of new energy vehicles. The purpose is to solve the defects of existing soft material water storage tanks, such as insufficient lateral compressive strength and easy overturning; and to avoid the problems of existing hard material water storage tanks, such as serious bottom leakage, large volume, heavy weight, difficulty in transportation and storage, and complicated splicing.
[0014] To achieve the above objectives, this utility model discloses a fencing for a water storage tank used to prevent reignition of new energy vehicles; it includes at least an inflatable frame and a flexible water-blocking component disposed on one side of the inflatable frame; the flexible water-blocking component includes a side water-blocking portion extending vertically and a bottom water-blocking portion extending horizontally; it also includes a plurality of diagonal ropes; the first end of each diagonal rope is connected to the side water-blocking portion and the second end is connected to the bottom water-blocking portion.
[0015] Furthermore, the inflatable frame is provided with an opening; the flexible water-blocking component is provided with a sealable splice at a position corresponding to the opening.
[0016] Furthermore, the splicing part is provided with a zipper or several Velcro straps on the inner side of the flexible water-blocking component; the splicing part is provided with several buckles on the outer side of the flexible water-blocking component; the zipper or Velcro straps on the inner side and the buckles on the outer side work together to achieve the sealing function of the splicing part.
[0017] Furthermore, a soft counterweight strip is provided at the edge of the bottom water-retaining part.
[0018] Furthermore, the inflatable frame includes several horizontally and vertically arranged inflatable columns; an inflatable channel is formed between adjacent inflatable columns.
[0019] Furthermore, the inflatable frame is provided with one or more inflation ports. This multi-port design improves inflation efficiency.
[0020] Furthermore, the inflatable frame is rectangular. This rectangular design better matches the shape of a car body, thus resulting in higher water utilization within the pool.
[0021] Furthermore, the cross-section of the inflatable column is circular. A circular or near-circular inflatable column can better adapt to the tension of gas under high compression, thereby allowing the inflatable frame structure to withstand higher air pressure, resulting in higher strength and better water-blocking effect for the enclosure of this invention.
[0022] Furthermore, several towing ropes are provided on the outer side of the inflatable frame.
[0023] The beneficial effects of this utility model are:
[0024] Due to the aforementioned structural design, this invention incorporates flexible water-blocking components within the inflatable frame. These components extend vertically and horizontally to form a water tank (without requiring a sealed bottom). In particular, the use of multiple diagonal bracing ropes improves the stress state of the enclosure's sidewalls under water storage conditions. When water is stored in the tank, water pressure acts simultaneously on the lateral tank body and the vertical tank bottom. These two opposing forces tension the bracing ropes, increasing their strength and distributing some of the water pressure on the enclosure's sidewalls to the tank bottom, where it is offset by the water's own weight. This increases the enclosure's, especially the sidewalls', resistance to overturning, effectively solving the problem in existing technologies where the sidewalls of flexible rectangular water tanks are easily overturned by water pressure.
[0025] This invention employs a flexible water-blocking component, resulting in better ground contact. Under the weight of the stored water, the bottom water-blocking portion of the flexible component is pressed more tightly against the ground, providing better leak prevention and adaptability to uneven surfaces. Furthermore, this invention can also incorporate a separate flexible counterweight strip on the inner side of the bottom water-blocking portion, further securing it to the ground. When water is poured into the pool, this effectively prevents the bottom water-blocking portion from being rolled up (detached from the ground) by water impact, thus further preventing pool water leakage.
[0026] This utility model features an inflatable structure that automatically unfolds upon inflation. After deflation, it can be easily folded or rolled up for storage, resulting in a small size and light weight, making it convenient for handling and transport by vehicles such as fire trucks.
[0027] This utility model can be an open-type structure, which can be directly enclosed around the anti-reignition new energy vehicle during use (eliminating the need for hoisting the anti-reignition new energy vehicle), greatly improving the convenience of use and saving time. Furthermore, due to its integrated structure, this utility model can be put into working condition with a single inflation, requiring only the opening to be joined, thus solving the problem of cumbersome splicing.
[0028] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0037] like Figures 1 to 7 As shown, a specific embodiment of the enclosure for a water storage tank used to prevent reignition of fires in new energy vehicles according to this utility model includes at least an inflatable frame 1 and a flexible water-blocking component 2 disposed inside the inflatable frame 1. The flexible water-blocking component 2 can be made of a commercially available soft waterproof fabric material; and the inflatable frame 1 can also be made of the same material.
[0038] The inflatable frame 1 includes several vertical inflatable columns 11 and horizontal inflatable columns 12; adjacent inflatable columns form a through inflation channel, and inflation is achieved through an inflation port 5 (obviously, there can also be multiple inflation ports, which would result in higher inflation efficiency).
[0039] The cross-section of the inflatable column is circular or nearly circular, which can better adapt to the tension of gas under high compression, thereby enabling the structure of the inflatable frame 1 to withstand higher air pressure, making the enclosure of this utility model stronger and better at blocking water.
[0040] The inflatable frame 1 and the flexible water-blocking component 2 can be obtained by existing bonding processes such as bonding, or by direct integral molding.
[0041] In this embodiment, the inflatable frame 1 is rectangular to better adapt to the specifications and shape of the anti-reignition new energy vehicle and improve the utilization rate of water. In other embodiments, the inflatable frame may also be circular or other specific shapes as required.
[0042] The flexible water-blocking member 2 includes a side water-blocking portion 21 extending vertically and a bottom water-blocking portion 22 extending laterally.
[0043] The side water-blocking part 21 and the bottom water-blocking part 22 can be a single piece of soft waterproof fabric, or two pieces of soft waterproof fabric that are respectively connected and fixed to the inflatable frame 1.
[0044] Importantly, the inflatable frame 1 in this invention may also include only a number of horizontal inflatable columns; or only a number of vertical inflatable columns. In particular, when several (or possibly only one) horizontal (or vertical) inflatable columns are closely attached together, the outer surfaces of the inflatable columns that intersect can replace the aforementioned side water-blocking parts.
[0045] This utility model also includes several inclined ropes 3. The first end 31 of each inclined rope 3 is fixedly connected to the side water-blocking part 21, and the second end 32 is fixedly connected to the bottom water-blocking part 22.
[0046] Generally, the first end 31 is positioned as close as possible to the top of the side water-blocking part 21, and the second end 32 is positioned as far as possible from the bottom water-blocking part 22, in order to maximize the improvement of the stress state.
[0047] Furthermore, the several inclined ropes 3 are preferably arranged in parallel in four different directions to balance the force.
[0048] In some other embodiments, the inflatable frame may be located on the inside, and the flexible water-blocking component may be located on the outside (but the bottom water-blocking portion still extends into the pool). In this case, the first end of the diagonal rope may also be fixed to the inflatable frame.
[0049] As an open-type enclosure, the inflatable frame 1 is provided with an opening 13; when in use, this utility model can be directly enclosed around the anti-reignition new energy vehicle (without the need for hoisting the anti-reignition new energy vehicle), which greatly improves the convenience of use.
[0050] Correspondingly, the flexible water-blocking component 2 is provided with a splicing part 23 at the position corresponding to the opening 13. This splicing part 23 obviously must be a sealed connection. Furthermore, the splicing part 23 has a zipper 231 or several Velcro straps (fasteners) on the inner side of the flexible water-blocking component 2, and several buckles 232 on the outer side of the flexible water-blocking component 2; the zipper or Velcro on the inner side and the buckles on the outer side work together to achieve the sealing function of the splicing part 23. This waterproof connection structure is existing technology and will not be described in detail here.
[0051] Of course, in some embodiments, especially for small-sized enclosures, the inflatable frame may not have openings.
[0052] To achieve better leak-proof performance, in some embodiments, a soft ballast band 4 is provided at the edge of the bottom water-retaining part 21 (away from the inflatable frame 1). More preferably, the density of the soft ballast band 4 is greater than that of water, effectively preventing the bottom water-retaining part from being rolled up (detached from the ground) by water impact when water is injected into the pool, thus better preventing pool water leakage. The soft ballast band 4 can be separate from the bottom water-retaining part 21.
[0053] To facilitate handling, several towing ropes 6 can be installed on the outside of the inflatable frame 1.
[0054] Specifically, in a practical application, the external shape of this utility model is a rectangle of 660mm × 360mm; the inner hole of the soft skirt 12 is a rectangular hole of 510mm × 210mm; the distance from the inner annular edge of the soft skirt 12 to the inner wall of the elastic annular inflatable wall 11 is 55mm; the distance from the position where each diagonal pull rope 4 is connected to the soft skirt 12 to the inner wall of the nearest elastic annular inflatable wall 11 is 35mm.
[0055] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
