Description

Technical Field

[0001] The present invention relates to the field of fire-fighting devices, and in particular to a mobile new energy vehicle fire-fighting device. Background Art

[0002] With the development of new energy vehicles, more and more new energy vehicles are parked in garages. These new energy vehicles usually carry batteries, most commonly lithium batteries. When new energy vehicles have problems such as overcurrent charging and collision, they are prone to fire problems. When new energy vehicles catch fire, there is a certain risk of explosion, which often endangers the safety of firefighters. Sometimes they can only let the flames burn until the fire is out before they approach to spray water, dry powder, etc. to extinguish the fire. This can easily cause nearby vehicles to burn and cause significant property losses.

[0003] Chinese patent document No. CN221513335U discloses a fire extinguishing square warehouse for new energy vehicles, which includes a square warehouse body that is sealed on all sides and opened at the top and bottom. A spray mechanism is arranged on the top of the square warehouse body, a hanging ring is arranged on the top of the square warehouse body, and a circle of sealing components is arranged at the bottom of the square warehouse body. The sealing components include a circle of soft silicone rubber strips, a circle of foam silicone rubber strips located outside the soft silicone rubber strips, and a circle of inflatable silicone rubber sealing airbag belts located between the soft silicone rubber strips and the foam silicone rubber strips. The lower half of the foam silicone rubber strips is located below the soft silicone rubber strips, the inflatable silicone rubber sealing airbag belt is provided with an inflatable joint, and positioning cylinders are fixedly arranged at the four corners of the bottom end of the square warehouse body. The spray mechanism includes a circle of spray pipes arranged on the top of the square warehouse body, a plurality of water mist spray heads arranged on the spray pipes, and a quick connector connected to the spray pipes. The above-mentioned fire extinguishing square warehouse needs to be hoisted by a lifting ring, but in actual use, in many places, such as underground garages, the crane cannot operate due to space limitations, which will greatly limit the use scenario of the fire extinguishing square warehouse.

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0025] Embodiment 1

[0026] like Figures 1 to 4As shown, the mobile new energy vehicle fire-fighting device provided in this embodiment includes at least one isolation plate 1, and a water supply pipeline is arranged inside the isolation plate 1. The water supply pipeline can be a separate water pipe, or the internal cavity of the fixed frame 13 and the extension frame 14 mentioned below can be directly used as the water supply pipeline. Usually, two isolation plates 1 are arranged. The two isolation plates 1 can be respectively arranged on both sides of the vehicle during firefighting, and are symmetrically arranged. The two isolation plates 1 are located on both sides of the vehicle to isolate the burning vehicle, thereby preventing the burning vehicle from transmitting the fire to the adjacent vehicles. At least one nozzle 2 is arranged on the inner wall of the isolation plate 1, and at least one nozzle is fixed on the water supply pipeline and is connected to the inside of the water supply pipeline. One end of the water supply pipeline is connected to the water inlet interface 3. In actual use, when water is passed into the water inlet interface 3, the water will be transferred to each nozzle 2 along the water supply pipeline, and then sprayed out from each nozzle 2, so as to extinguish the fire of the new energy vehicle on fire. A drain port 40 is arranged at the bottom of the isolation plate 1, and the water in the isolation plate 1 can be discharged through the drain port 40, so that the water can be drained when the fire-fighting device is not in use. The above-mentioned isolation plate 1 can effectively isolate the fire source, especially for new energy vehicles. Since new energy vehicles have the risk of battery explosion, firefighters cannot approach to extinguish the fire at will after the fire occurs. The isolation plate 1 provided in the present application can not only isolate the fire source but also water the fire source, so as to achieve the purpose of extinguishing the fire.

[0027] In order to isolate the car from both sides and ensure that the two isolation panels 1 can be used at the same time to prevent them from transmitting the fire to nearby cars, the mobile new energy vehicle fire-fighting device further includes at least one connecting rod 4. The number of isolation panels 1 is two, namely the first isolation panel 11 and the second isolation panel 12. The outer frame of the first isolation panel 11 is connected to the outer frame of the second isolation panel 12 through at least one connecting rod 4. The connecting action of the connecting rod 4 can make the first isolation panel 11 and the second isolation panel 12 connected to a rectangular frame and form a whole. Combined with the roller 7, a movable new energy vehicle fire truck can be formed. The first isolation panel 11 and the second isolation panel 12 are usually symmetrically distributed on both sides of the car. When a movable rectangular frame is formed, that is, when a mobile new energy vehicle fire-fighting device is formed, the rectangular frame can be pushed to the two sides of the burning car, so that the first isolation panel 11 and the second isolation panel 12 can act as baffles for firefighters to approach the burning car. Further preferably, the mobile new energy vehicle fire-fighting device also includes four connecting rods 4, one of the four connecting rods 4 is a detachable connecting rod 45, and the detachable connecting rod 45 is used to connect the bottom first end of the first isolation plate 11 and the bottom first end of the second isolation plate 12, and one end of the remaining three connecting rods 4 is respectively connected to the bottom second end, the top first end, and the top second end of the first isolation plate 11, and the other ends of the remaining three connecting rods 4 are respectively connected to the bottom second end, the top first end, and the top second end of the second isolation plate 12. When used specifically, the detachable connecting rod is not installed first, so that a rectangular frame with a notch is formed, and then the firefighters move the rectangular frame from the notch to the two sides of the burning car. When the burning car is located in the middle of the rectangular frame, the detachable connecting rod is installed to form a more stable rectangular frame structure.

[0028] In order to enhance the isolation effect of the isolation board 1 on the burning car, the isolation board 1 further includes a fireproof cloth 5, and the fireproof cloth 5 is sleeved on the fixed frame 13 and / or the extension frame 14 is sleeved on the fireproof cloth 5, that is, the entire isolation board 1 is covered with the fireproof cloth 5, so that the flames cannot pass through the isolation board 1 from both sides.

[0029] In order to facilitate water spraying from the bottom of the car, further, a swingable nozzle 6 is provided at the bottom of the fixed frame 13, and the swingable nozzle 6 is rotatably connected to the fixed frame 13. The inner cavity of the swingable nozzle 6 is also connected to the inner cavity of the fixed frame 13. The swingable nozzle 6 is provided with at least one nozzle 2, and water can be sprayed to the bottom of the car through the nozzle 2. The swingable nozzle 6 can be used selectively. When it is not in use, it is usually located at the bottom of the lower crossbeam 132 of the fixed frame 13; when it is used, the swingable nozzle 6 can be rotated so that its nozzle 2 is located at the bottom of the car, and then water is sprayed.

[0030] The mobile new energy vehicle fire-fighting device provided in this embodiment also includes at least one roller 7, at least one roller 7 is fixed under the isolation plate 1, and the roller 7 can be provided with a high temperature resistant roller 7 with a brake. In order to improve its high temperature resistance, the roller 7 can be made of metal material. The roller 7 is preferably arranged under each column of the first isolation plate 11 and the second isolation plate 12 (such as: the middle column 133, the fixed column 134 and the movable column 143 as described below), so that the mobile new energy vehicle fire-fighting device can be easy to push, and being arranged directly under the column is also conducive to preventing the crossbeam from deforming due to load-bearing.

[0031] The mobile new energy vehicle fire-fighting device provided in this embodiment also includes a window breaker 30, which can be set on the first isolation plate 11 or the second isolation plate 12. The window breaker 30 facilitates firefighters to break windows during rescue, so as to rescue people and important property in the car in time.

[0032] Embodiment 2

[0033] like Figures 1 to 4 As shown, the mobile new energy vehicle fire-fighting device provided in this embodiment includes at least one isolation plate 1, a water supply pipeline is arranged inside the isolation plate 1, at least one nozzle 2 is arranged on the inner wall of the isolation plate 1, at least one nozzle is fixed on the water supply pipeline and is connected with the inside of the water supply pipeline, and one end of the water supply pipeline is connected to the water inlet interface 3.

[0034] The difference between the second embodiment and the first embodiment is that:

[0035] The mobile new energy vehicle fire-fighting device is retractable, and the isolation plate 1 includes a fixed frame 13 and at least one level of extension frame 14. Usually, a one-level or two-level extension frame 14 is set. When a two-level extension frame 14 is set, it continues to extend on the basis of the one-level extension frame 14. Although theoretically, multiple levels of extension frames 14 can be set infinitely, in practice, considering the manufacturing cost and ease of use, usually at most three levels of extension frames 14 are set. The following only explains the case of setting a one-level extension frame 14, and the remaining levels can be deduced by analogy.

[0036] The isolation plate 1 includes a fixed frame 13 and an extension frame 14. At this time, the extension frame 14 is only one level. One end of the extension frame 14 extends into the fixed frame 13, and the extension frame 14 slides with the fixed frame 13 to achieve the extension and contraction of the extension frame 14 relative to the fixed frame 13, that is, the expansion and contraction of the extension frame 14 is achieved. The internal cavity of the extension frame 14 is connected to the internal cavity of the fixed frame 13, which makes it possible to set a nozzle 2 on the extension frame 14. After the water flows through the fixed frame 13, it flows through the extension frame 14 and finally sprays out from the nozzle 2 on the extension frame 14. The purpose of setting the extension frame 14 is to shorten the length dimension of the mobile new energy vehicle fire-fighting device to facilitate the transportation of fire trucks. This is because the length of the mobile new energy vehicle fire-fighting device is usually longer than the length of most cars, so as to achieve the purpose of fully blocking cars of different lengths. If it is not extended and retracted, the transportation of the fire truck is very difficult. In actual applications, when a two-stage extension frame 14 is set, the length dimension of the mobile new energy vehicle fire-fighting device is shortened by about 3 / 2, and even a small fire truck can be transported.

[0037] Further preferably, the fixing frame 13 includes an upper crossbeam 131, a lower crossbeam 132, a middle column 133, a solid column 134 and at least one middle crossbeam 135. The upper crossbeam 131, the lower crossbeam 132, the middle column 133 and the solid column 134 form a rectangular frame to form the main structure of the fixing frame 13. The middle crossbeam 135 is conducive to enhancing the overall firmness of the fixing frame 13 and is conducive to installing the nozzle 2 in the middle position of the fixing frame 13. The top of the solid column 134 is connected to the upper crossbeam 1 31, the bottom end of the solid column 134 is connected to one end of the lower cross beam 132, one end of at least one middle cross beam 135 is connected to the solid column 134, the top of the middle column 133 is connected to the other end of the upper cross beam 131, the bottom end of the middle column 133 is connected to the other end of the lower cross beam 132, and the other end of at least one middle cross beam 135 is connected to the middle column 133. By reasonably setting the number and position of the middle cross beams 135, each nozzle 2 can be installed in an ideal position. The extension frame 14 includes an upper moving beam 141, a lower moving beam 142, a moving column 143 and at least one moving cross beam 144. The upper moving beam 141, the lower moving beam 142 and the moving column 143 form a U-shaped frame. The top of the moving column 143 is connected to one end of the upper moving beam 141, the bottom end of the moving column 143 is connected to one end of the lower moving beam 142, and one end of at least one moving cross beam 144 is connected to the moving column 143. The other end of the upper moving beam 141 extends into the upper cross beam 131 and slides with the upper cross beam 131, the other end of the lower moving beam 142 extends into the lower cross beam 132 and slides with the lower cross beam 132, and at least one moving cross beam 144 extends into the corresponding at least one middle cross beam 135 and slides with the corresponding middle cross beam 135, so that the extension frame 14 as a whole can be extended and retracted relative to the fixed frame 13. The internal cavity of the upper moving beam 141 is connected to the internal cavity of the upper cross beam 131 and / or the internal cavity of the lower moving beam 142 is connected to the internal cavity of the lower cross beam 132 and / or the internal cavity of at least one moving cross beam 144 is selectively connected to the internal cavity of the corresponding middle cross beam 135. In actual use, the moving cross beam 144 and the middle cross beam 135 can be selectively set to whether water is passed through, depending on the installation of the nozzle 2. The upper cross beam 131 and the lower cross beam 132 generally pass water. The upper cross beam 131 is generally provided with at least one nozzle 2 for spraying water downwards, and the lower cross beam 132 is also generally selected to pass water due to the swingable nozzle 6 described below. In addition, a handle 20 is usually provided on the moving column 143, and the extension frame 14 can be pulled by the handle 20 to be extended and retracted.

[0038] In order to connect the fixing frame 13 of the first isolation plate 11 as a whole to form a rectangular frame, the extension frame 14 is only one level at this time. Further preferably, the fixing frame 13 of the first isolation plate 11 is connected to the fixing frame 13 of the second isolation plate 12 through three connecting rods 4, and the three connecting rods 4 are respectively a first connecting rod 41, a second connecting rod 42 and a third connecting rod 43.

Specifically, the top end and the other end of the fixing frame 13 are respectively one end and the other end of the upper crossbeam 131. The bottom end of the fixing frame 13 of the first isolation plate 11 is connected to the bottom end of the fixing frame 13 of the second isolation plate 12 in a hinged manner through the third connecting rod 43. Specifically, the bottom end of the fixing frame 13 is one end of the lower crossbeam 132. The connection of the three connecting rods 4 makes The mobile new energy vehicle fire-fighting device constitutes a rectangular parallelepiped frame with a notch, the extension frame 14 of the first isolation plate 11 is connected to the second isolation plate 12 through the fourth connecting rod 44 and the detachable connecting rod 45, and the top end of the extension frame 14 of the first isolation plate 11 is connected to the top end of the extension frame 14 of the second isolation plate 12 in a hinged manner through the fourth connecting rod 44. Specifically, the top end of the extension frame 14 is one end of the upper moving beam 141, and the bottom end of the extension frame 14 of the first isolation plate 11 is connected to the second isolation plate 12 through the detachable connecting rod 45. The bottom end of the extension frame 14 away from the plate 12 is detachably connected. Specifically, the bottom end of the extension frame 14 is one end of the downward beam 142. Usually, pins or slots are provided at both ends of the detachable connecting rod. If pins are provided at both ends of the detachable connecting rod, sleeves compatible with the pins are provided at the bottom end of each of the two extension frames 14; if slots are provided, the two ends of the detachable connecting rod are directly inserted into the corresponding slots, and the detachable connection of the detachable connecting rod 45 is achieved by plug-in cooperation or snap-in cooperation with the pin or the slot and the two sleeves.Further preferably, in order to realize the overall expansion or folding of the rectangular frame, further preferably, the first link 41 is provided with a first hinge 411 for folding in the middle, and the first link 41 is bent toward the second link 42, the second link 42 is provided with a second hinge 421 for folding in the middle, and the second link 42 is bent toward the first link 41, the third link 43 is provided with a third hinge 431 for folding in the middle, and the third link 43 is bent toward the detachable link 45, and the fourth link 44 is provided with a fourth hinge 441 for folding in the middle, and the fourth link 44 is bent toward the second link 42.
