Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and specifically relates to a fire-fighting cofferdam for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] The battery pack of a new energy vehicle is typically located at the bottom of the vehicle chassis. Under abnormal conditions such as cell failure, collisions, and extreme circumstances like internal or external short circuits and thermal runaway, it is prone to smoke and fire. This makes explosions and spontaneous combustion common, posing a serious threat to life, property, and personal safety. Furthermore, a new energy vehicle fire can be long and intense, making it difficult to extinguish the fire with conventional water cannons, which cannot directly reach the battery pack at the bottom of the vehicle. Fire extinguishing agents also cannot effectively reach the battery modules, and the firefighting process presents unsafe conditions such as high voltage and explosions.

[0004] In recent years, firefighters have developed various water cannons capable of spraying fire from deep beneath the vehicle to extinguish fires. These cannons continuously impact the exterior of the battery pack with water, lowering the internal temperature and extinguishing the fire from the outside. However, this process is time-consuming, cooling the battery pack from the outside inward, resulting in low cooling efficiency. Furthermore, it is difficult to determine the internal condition of the battery pack, and there is still a risk of the battery pack reigniting during transport of a self-ignited electric vehicle, causing secondary damage. Utility Model Content

[0005] In response to the shortcomings of the above-mentioned existing technologies, the utility model provides a new energy vehicle fire extinguishing cofferdam, which has a simple structure and is easy to use.

[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, an embodiment of the present utility model provides a fire extinguishing cofferdam for new energy vehicles, which includes a base portion 1, a fence portion 2 and a plurality of barrier portions 3.

[0041] Specifically, the base portion 1 is the bottom surface of the cofferdam, which is an annular plane structure and contacts the ground when in use.

[0042] The fence portion 2 is a side surface of the cofferdam and has a cylindrical structure. The lower edge of the fence portion 2 is connected to the outer edge of the annular base portion 1.

[0043] Several baffles 3 are arranged at intervals on the inner side of the fence part 2. All baffles 3 are triangular surface structures. One side of the triangular surface structure is connected to the inner side of the fence part 2, one side is connected to the upper side of the base part 2, and the other side faces the inner side of the cofferdam.

[0044] The base portion 1, the fence portion 2 and the barrier portion 3 are all made of soft, foldable fire-resistant materials.

[0045] A base portion 1 and a fence portion 2 are provided, and a number of baffle portions 3 are provided for connection, so that the cross-section of the cofferdam is a triangular structure. When in use, the base portion 1 contacts the ground, provides an attachment surface, and can effectively prevent water flow or fire extinguishing agent from leaking; the baffle portions 3 connect the base portion 1 and the fence portion 2 to provide restraint and support, so that the cofferdam is stable and reliable after water storage.

[0046] This new energy vehicle fire extinguishing cofferdam features a simple structure, small size, and light weight, making it easy for rescue workers to carry with them. It requires only two to three people to operate, is simple to install, and can be adapted to different terrains, making it convenient and flexible to use. Once installed, the cofferdam is filled with water or a fire extinguishing agent, such as foam, to immerse the vehicle. This allows for rapid forced cooling, saving firefighting water and agent, as well as cooling time. This ensures effective firefighting and cooling, improves safety, and effectively prevents secondary damage from battery pack re-ignition.

[0047] Preferably, the base 1, the fence 2 and the barrier 3 are all made of glass fiber base cloth with double-sided plastic polyurethane rubber (TPU) fireproof and waterproof coating, which is a Class A fireproof and three-proof cloth with waterproof, fireproof and foldable functions.

[0048] Preferably, the fence portion 2 and the base portion 1 are integrally formed. That is, the fence portion 2 and the base portion 1 are formed by cutting and folding a continuous three-proof cloth or other soft refractory material, which simplifies production and reduces seam processing and gap leakage prevention treatment.

[0049] In one embodiment, a lightweight foam float 4 is provided on the inner upper portion of the fence portion 2. When filled with water, it can provide upward buoyancy traction for the fence portion 2 and the barrier portion 3, so that the fence portion 2 and its upper opening can better support water storage and avoid collapse.

[0050] In one embodiment, a communicating opening is provided on the same side of the base portion 1 and the fence portion 2, i.e., the cofferdam is disconnected at this opening. Adaptive hook-and-loop fasteners 5 are provided on both sides of the opening. Preferably, the hook-and-loop fasteners 5 are adapted nylon hook-and-loop fasteners (male and female), respectively. The cofferdam can be attached or detached via the hook-and-loop fasteners 5. The provision of the opening and the hook-and-loop fasteners 5 facilitates the side-mounting of the rescue vehicle, making installation more convenient and folding the cofferdam more convenient.

[0051] Preferably, a plurality of drawstrings 6 are provided at intervals on the lower outer side of the fence portion 2 , which can be pulled and fixed via the drawstrings 6 , so as to facilitate the unfolding of the cofferdam and make the installation of the cofferdam more stable.

[0052] Preferably, the upper part of the fence part 2 is tilted inward, forming a cylindrical structure with a small top and a large bottom. The upper edge of the fence part 2 and the inner edge of the base part 1 are on the same vertical cylindrical side, that is, the projection of the upper edge of the fence part 2 overlaps with the inner edge of the base part 1.

[0053] Furthermore, several barrier parts 3 are all right-angled triangle surface structures, the bottom side of which is connected to the base part 1, and the barrier part 3 is perpendicular to the base part 1; the hypotenuse of the barrier part 3 is connected to the fence part 2; the side facing the inside of the cofferdam is perpendicular to the bottom side, that is, all the sides of the barrier parts 3 facing the inside of the cofferdam are parallel, and the upper end is connected to the upper edge of the fence part 2, and the lower end is connected to the inner edge of the base part 1.

[0054] The upper part of the fence part 2 is tilted inward, and the barrier part 3 completely connects the base part 1 and the fence part 2, so that the structure is stable and reliable after the cofferdam is filled with water or fire extinguishing agent, and is not prone to collapse, displacement and other problems.

[0055] The cofferdam is a synthetic rectangular cylinder that can better match the shape of the vehicle body and reduce the amount of water or fire extinguishing agent used.

[0056] The height of the cofferdam is preferably set to be greater than or equal to 1.5 meters, and the depth of the water or fire extinguishing agent can reach at least 1.5 meters, which can well immerse the vehicle to be extinguished and meet the rescue needs of new energy vehicles.

[0057] In summary, the utility model of the new energy vehicle fire extinguishing cofferdam has a simple structure, small size, light weight, and is convenient for rescue personnel to carry with them; it only requires 2 to 3 people to operate, is easy to install, and can be installed according to different terrains, so it is easy and flexible to use. An opening and a magic buckle are provided, which can be pulled up by two people, making it convenient to enclose the vehicle to be rescued in the middle, and the magic buckle is glued to form a complete cofferdam, which is quick and easy to install. After the cofferdam is enclosed, water or foam and other fire extinguishing agents are injected into the cofferdam to immerse the vehicle in it, which can achieve rapid forced cooling, save the amount of water or fire extinguishing agent used for fire fighting, and save the fire extinguishing cooling time. The fire extinguishing cooling effect is more guaranteed, the safety is higher, and the secondary damage caused by the re-ignition of the battery pack can be effectively avoided.
