Description

Technical Field

[0001] The utility model belongs to the technical field of automobile fire extinguishing, in particular to an isolated water-cooled automobile fire extinguishing cover. Background Art

[0002] With the popularization and development of new energy vehicles, automobile fire accidents caused by thermal runaway of power batteries and automobile defects and failures have increased year by year, attracting widespread attention.

[0003] In response to car fires, especially electric vehicle fires, personnel have designed and developed a number of technical devices, such as the patent "A rapid disposal device for extinguishing electric vehicle fires" (202022913248.0), which uses a baffle group and a spray pipe to form a closed area around the burning vehicle, and uses the surrounding spray pipes to spray water or fire extinguishing agents to extinguish the fire.

[0004] However, since electric vehicle batteries are all installed at the bottom of the car, electric vehicle fires are usually caused by deflagration and jet fire caused by thermal runaway gas production of the battery. The above patented technical solution only sprays water or fire extinguishing agents on the burning vehicle in a closed area around it. It is difficult to effectively act on the thermal runaway battery cells under the vehicle to achieve rapid fire extinguishing. To solve this problem, the patent "A fire blanket for rapid fire fighting in automobiles (202120647360.6)" uses fire hoses and PVC pipes as flexible pipes fixed to the edge of the fire blanket to increase the weight of the fire blanket and improve the fire blanket's ability to cover the burning car and isolate the air. At the same time, the pipe is connected to the fire water or liquid fire extinguishing agent to spray on the burning vehicle to achieve the purpose of rapid fire extinguishing. The patented technical solution is to combine a water hose with a fire blanket, hoping to achieve air-isolated fire extinguishing while spraying fire extinguishing agent. However, in actual use, it is found that the sprayed water or fire extinguishing agent will suck in a large amount of air due to the reaction force, and the sprayed water or fire extinguishing agent will be lost in large quantities. The inhibitory effect of extinguishing the thermal runaway battery cell by only relying on heat absorption and cooling is not prominent. Moreover, the technical design increases the weight of the fire blanket, and heavy objects such as sandbags need to be hung on it in the later stage. The operation is cumbersome and it will also be dangerous for firefighters.

[0005] To solve this problem, the patent "A fire fighting device for automobile chassis (202222369491.x)" discloses a technical solution that uses a motor-driven water spray rack and a quick-connect pipe design. The water spray rack can be moved to the bottom of the burning car by remote control or manual mode, and the fire extinguishing agent is sprayed from the car chassis using the nozzle on the water spray rack to extinguish the fire. However, since the car chassis is usually equipped with a "safety protection plate" to encapsulate and protect important components such as batteries, the sprayed water cannot contact them. The probability of directly applying the fire extinguishing agent to the battery pack or spraying the jet flame for cooling and fire extinguishing is very low. The sprayed fire extinguishing agent cannot directly act on the thermal runaway battery cell, and once the jet fire formed by the thermal runaway gas production of the battery cell ignites the car interior, tires and other parts, the patented technology cannot be effectively suppressed, and the sprayed fire extinguishing agent will be lost in large quantities, and it cannot continue to play a role in the thermal runaway battery cell. There are problems such as low efficiency of fire extinguishing suppression and poor fire extinguishing suppression effect. Utility Model Content

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] like Figure 1 The invention discloses an isolated water-cooled automobile fire extinguishing hood, comprising a rectangular flexible fire extinguishing hood body, which is constructed by weaving and bonding flexible refractory materials and composite materials, such as nano-aerogel felt. The flexible fire extinguishing hood body comprises a closed-loop wall body 1 formed by four wall panels 11 in front, rear, left and right, which enclose a car containing cavity for containing a car. The top and bottom of the car containing cavity are both open, and the bottom opening 7 facilitates the car to enter the car containing cavity so as to contain the car in the annular wall. The top opening of the car containing cavity corresponds to a cover body 2, and the top opening of the car containing cavity is sealed by the cover body 2. At this time, the fire extinguishing hood as a whole presents a bottomless pentahedral structure, so as to facilitate the cover buckle of the car.

[0029] In the utility model, the four wall panels 11 constituting the closed-loop wall 1 are respectively enclosed by the inner wall surface, the outer wall surface, the top surface and the bottom surface, and each forms a cavity which is open at the left and right ends. The four wall panels 11 have a total of four cavities, and every two adjacent wall panels 11 are connected and communicated, and the connection between the two adjacent wall panels 11 should be rounded to prevent sharp corners from appearing at the connection. After the four wall panels are connected, the four cavities are connected to form a closed-loop communication cavity, that is, a closed-loop cavity is formed in the closed-loop wall 1. At least one wall panel 11 in the closed-loop wall 1 has a fire hose interface 3 at the bottom of the outer wall surface, so as to quickly connect with the municipal fire hose or the fire truck hose to fill water, and inject the fire extinguishing water into the annular cavity. The upper ends of the inner wall surfaces of the four wall panels 11 of the closed-loop wall 1 are respectively provided with nozzles 4, and the nozzles 4 are preferably flexible nozzles. The fire-extinguishing water injected into the annular cavity is sprayed toward the car containing cavity of the closed-loop wall 1 through the nozzles 4, and the burning car contained and controlled by the car containing cavity is sprayed with water to cool down and extinguish the fire. The water sprayed from the nozzles 4 gathers into a pool in the closed-loop wall to extinguish the fire of the burning battery.

[0030] The utility model is a three-dimensional cover formed by a rounded and bottomless pentahedron, which is used to cover the burning car from top to bottom. It has a certain flexibility and can be compressed and stored in parking garage fire hydrants and micro fire stations, parking lots and ocean freighter storage, manufacturer emergency stations and other management to be ready for battle at all times, or folded and hung in the upper position of the storage area and ship parking area. Once the vehicle is on fire, two people can lift or a mechanical arm can hang the cover on the accident vehicle. The four wall panels 11 of the fire extinguishing cover automatically droop to surround the burning vehicle. At the same time, the water inlet device connected to the fire hose interface 3 is opened, and fire extinguishing water is injected into the closed-loop cavity of the closed-loop wall 1. The upper and lower compressed state of the closed-loop wall 1 is quickly filled with pressure water to expand and increase to form a stable water wall, and the positive pressure presses the bottom of the closed-loop wall 1 tightly against the ground. After the closed-loop cavity is filled with water, the closed-loop wall 1 can maintain a stable upright state, so that it can maintain a stable and inclusive state. The bottom surface of the fire extinguishing hood is tightly pressed against the ground to prevent the water ejected from the nozzle 4 from flowing out of the car cavity. A water pool can be quickly formed in the car cavity to immerse the car in water. The cover body 2 of the fire extinguishing hood seals and blocks the exchange of air between the car cavity and the outside air, so that the entire car is in an oxygen-deficient and water-immersed cooling state. Continuous hydraulic jetting causes continuous cooling and oxygen deficiency, thereby achieving rapid fire extinguishing.

[0031] In the utility model, flexible tie bars are arranged in the cavities of the four wall panels 11 of the closed-loop wall 1, and the flexible tie bars are bonded or vulcanized to the inner and outer wall surfaces of the closed-loop wall 1, and the inner and outer wall surfaces are connected, and the flexible tie bars are cross-linked with each other to form a grid-like flexible tie bar structure 12. The flexible tie bar structure 12 can improve the strength of the closed-loop wall 1, so that it can maintain a stable spatial shape in a water-filled state and stand upright as a whole, and the cover is buckled around the burning car to form a closed hexahedral space to quickly extinguish the fire of the car.

[0032] In the utility model, the cover body 2 is overlapped on the top surface of the closed-loop wall body 1, and its four sides or one group of opposite sides are connected to the closed-loop wall body 1 through fireproof velcro or fireproof binding tape. Or one side of the cover body 2 is bonded to the closed-loop wall 1 or fixedly connected by vulcanization or connected by hinge 6, and the other three sides are connected to the closed-loop wall 1 through fireproof velcro or fireproof binding tape. Or one side of the cover body 2 is bonded to the closed-loop wall 1 or fixedly connected by vulcanization or connected by hinge 6, and the other side is connected to the closed-loop wall 1 through fireproof velcro or fireproof binding tape. This structure enables the cover body 2 to be opened, Figure 2 As shown, after the firefighting is completed, the cover 2 can be opened to check the firefighting status.

[0033] In the utility model, at least one group of two facing wall panels 11 of the closed-loop wall 1 are provided with flexible handles 5 at the lower part of the outer wall surface, so as to facilitate manual grasping or connection and lifting with lifting equipment.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
