Description

Technical Field

[0001] This utility model relates to the field of fire-fighting devices, and in particular to a mobile vehicle fire-fighting device. Background Technology

[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, commonly lithium batteries. When new energy vehicles experience problems such as overcurrent during charging or collisions, they are prone to catching fire. When a new energy vehicle catches fire, it poses a certain risk of explosion, which often endangers the safety of firefighters. Sometimes, the only option is to let the flames burn until the fire is almost extinguished before approaching to spray water or dry powder to put out the fire. This can easily lead to nearby vehicles catching fire and causing significant property damage.

[0003] Chinese patent document CN221513335U discloses a fire extinguishing container for new energy vehicles. The fire extinguishing container for new energy vehicles includes a container body that is sealed on all four sides and open at the top and bottom. A spray mechanism is provided on the top of the container body. A lifting ring is provided on the top of the container body. A sealing assembly is provided at the bottom of the container body. The sealing assembly includes a ring of soft silicone rubber strips, a ring of foam silicone rubber strips located outside the soft silicone rubber strips, and a ring of inflatable silicone rubber sealing airbags 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 airbags are provided with an inflation connector. Positioning cylinders are fixedly provided at the four corners of the bottom of the container body. The spray mechanism includes a ring of spray pipes provided on the top of the container body, multiple water mist spray heads provided on the spray pipes, and quick connectors connected to the spray pipes. The aforementioned fire extinguishing container needs to be hoisted using lifting rings. However, in actual use, in many places, such as underground parking garages, cranes cannot operate due to space limitations, which greatly restricts the application scenarios of the fire extinguishing container.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1 to 4As shown, the mobile car firefighting device provided in this embodiment includes at least one isolation plate 1. The isolation plate 1 is equipped with a water supply pipe. The water supply pipe can be a separate water pipe, or it can directly utilize the internal cavity of the fixing frame 13 and the extension frame 14 mentioned below as the water supply pipe. Usually, two isolation plates 1 are provided. The two isolation plates 1 can be set on both sides of the car during firefighting and are arranged symmetrically. The two isolation plates 1 located on both sides of the car can effectively isolate the burning car, thereby preventing the burning car from spreading the fire to the adjacent car. At least one nozzle 2 is provided on the inner wall of the isolation plate 1. The nozzle is fixed to and connected to the water supply pipe. One end of the water supply pipe is connected to the water inlet 3. In actual use, when water is supplied to the water inlet 3, the water is transmitted along the water supply pipe to each nozzle 2 and then sprayed out from each nozzle 2, thereby extinguishing the fire in the new energy vehicle. A drain outlet 40 is provided at the bottom of the isolation plate 1, through which water can be drained from the isolation plate 1, allowing it to dry when the firefighting device is not in use. The isolation plate 1 effectively isolates the fire source, especially for new energy vehicles. Due to the risk of battery explosion in new energy vehicles, firefighters cannot easily approach to extinguish the fire. The isolation plate 1 provided in this application not only isolates the fire source but also sprays water onto the fire source, thereby achieving the purpose of extinguishing the fire.

[0028] To isolate the fire from both sides of the vehicle and ensure that both isolation panels 1 can be used simultaneously to prevent the fire from spreading to nearby vehicles, the mobile vehicle firefighting device further includes at least one connecting rod 4. The isolation panels 1 consist of two blocks, namely a first isolation panel 11 and a 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. Through the connecting action of the connecting rod 4, the first isolation panel 11 and the second isolation panel 12 can be connected into a cuboid frame and form a whole. Combined with the rollers 7, a mobile 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 vehicle. When a movable cuboid frame is formed, that is, when a mobile vehicle firefighting device is formed, the cuboid frame can be pushed to move towards both sides of the burning vehicle, so that the first isolation panel 11 and the second isolation panel 12 can act as barriers for firefighters to approach the burning vehicle. More preferably, the mobile vehicle firefighting device also includes four connecting rods 4, one of which is a detachable connecting rod 45. 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. One end of the other three connecting rods 4 is connected to the bottom second end, top first end, and top second end of the first isolation plate 11, respectively, and the other end of the other three connecting rods 4 is connected to the bottom second end, top first end, and top second end of the second isolation plate 12, respectively. In actual use, the detachable connecting rod is not installed first, thus forming a cuboid frame with a notch. Then, the firefighters move the cuboid frame from the notch to both sides of the burning vehicle. When the burning vehicle is in the middle of the cuboid frame, the detachable connecting rod is then installed, thereby forming a more stable cuboid frame structure.

[0029] To further enhance the isolation effect of the isolation plate 1 on the burning vehicle, the isolation plate 1 also includes a fireproof cloth 5. The fireproof cloth 5 is fitted on the fixing frame 13 and / or the fireproof cloth 5 is fitted on the extension frame 14. That is, the entire isolation plate 1 is covered with fireproof cloth 5, so that flames cannot pass through the isolation plate 1 from both sides.

[0030] To facilitate water spraying from the bottom of the car, a swingable nozzle 6 is further provided at the bottom of the mounting bracket 13. The swingable nozzle 6 is rotatably connected to the mounting bracket 13, and its internal cavity is also connected to the internal cavity of the mounting bracket 13. At least one nozzle 2 is provided on the swingable nozzle 6, through which water can be sprayed onto the bottom of the car. The swingable nozzle 6 can be used selectively. When not in use, it is usually located at the bottom of the lower crossbeam 132 of the mounting bracket 13; when in use, the swingable nozzle 6 can be rotated so that its nozzle 2 is located at the bottom of the car before water spraying.

[0031] The mobile vehicle firefighting device provided in this embodiment also includes at least one roller 7, which is fixed below the isolation plate 1. The roller 7 may be equipped with high temperature resistance and a brake. To improve its high temperature resistance, the roller 7 may be made of metal. The roller 7 is preferably located below each column of the first isolation plate 11 and the second isolation plate 12 (hereinafter referred to as: central column 133, fixed column 134 and movable column 143), so that the mobile vehicle firefighting device can be easily pushed, and being located directly below the column also helps to prevent the crossbeam from deforming due to load.

[0032] The mobile vehicle firefighting device provided in this embodiment also includes a window breaker 30. The window breaker 30 can be installed on either the first isolation plate 11 or the second isolation plate 12. The window breaker 30 facilitates firefighters to break windows during rescue operations, and promptly rescues people and important property inside the vehicle.

[0033] Example 2

[0034] like Figures 1 to 4 As shown, the mobile vehicle fire-fighting device provided in this embodiment includes at least one isolation plate 1. A water supply pipeline is provided inside the isolation plate 1. At least one nozzle 2 is provided on the inner side wall of the isolation plate 1. The at least one nozzle is fixed on the water supply pipeline and connected to the inside of the water supply pipeline. One end of the water supply pipeline is connected to the water inlet 3.

[0035] The difference between Example 2 and Example 1 is that:

[0036] The mobile vehicle firefighting device is retractable. The isolation plate 1 includes a fixed frame 13 and at least one level of extension frame 14. Usually, one or two levels of extension frame 14 are set. When two levels of extension frame 14 are set, it is an extension based on the one level of extension frame 14. Theoretically, multiple levels of extension frame 14 can be set indefinitely. In practice, considering manufacturing costs and ease of use, a maximum of three levels of extension frame 14 are usually set. The following description only focuses on the case of setting one level of extension frame 14. The other levels can be deduced by analogy.

[0037] The isolation plate 1 includes a fixed frame 13 and an extension frame 14. At this time, the extension frame 14 is only one stage. One end of the extension frame 14 extends into the fixed frame 13. The extension frame 14 and the fixed frame 13 are slidably engaged, thereby realizing the extension and retraction of the extension frame 14 relative to the fixed frame 13, that is, realizing the expansion and contraction of the extension frame 14. The internal cavity of the extension frame 14 is connected to the internal cavity of the fixed frame 13, which allows nozzles 2 to be installed on the extension frame 14. Water flows through the fixed frame 13 and then through the extension frame 14, finally spraying out from the nozzles 2 on the extension frame 14. The purpose of setting the extension frame 14 is to shorten the length of the mobile vehicle fire-fighting device, making it easier for fire trucks to transport. This is because the length of the mobile vehicle fire-fighting device is usually longer than the length of most vehicles, in order to effectively block vehicles of different lengths. Without extension and retraction, it would be very difficult to transport fire trucks. In practical applications, when two stages of extension frames 14 are set, the length of the mobile vehicle fire-fighting device is shortened by about 3 / 2, so that even small fire trucks can be transported.

[0038] More preferably, the fixing frame 13 includes an upper crossbeam 131, a lower crossbeam 132, a central column 133, a fixed column 134, and at least one central crossbeam 135. The upper crossbeam 131, lower crossbeam 132, central column 133, and fixed column 134 form a rectangular frame, constituting the main structure of the fixing frame 13. The central crossbeam 135 not only enhances the overall stability of the fixing frame 13 but also facilitates the installation of the nozzle 2 in the middle position of the fixing frame 13. The top of the fixed column 134 is connected to the upper crossbeam 132. One end of 31 is connected, the bottom end of the fixed column 134 is connected to one end of the lower crossbeam 132, one end of at least one middle crossbeam 135 is connected to the fixed column 134, the top end of the middle column 133 is connected to the other end of the upper crossbeam 131, the bottom end of the middle column 133 is connected to the other end of the lower crossbeam 132, and the other end of at least one middle crossbeam 135 is connected to the middle column 133. By reasonably setting the number and position of the middle crossbeams 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 crossbeam 144. The upper moving beam 141, the lower moving beam 142, and the moving column 143 form a U-shaped frame. The top end of the moving column 143 is connected to one end of the upper moving beam 141, and the bottom end of the moving column 143 is connected to one end of the lower moving beam 142. One end of the at least one moving crossbeam 144 is connected to the moving column 143. The other end of the upper moving beam 141 extends into and slides with the upper crossbeam 131. The other end of the lower moving beam 142 extends into and slides with the lower crossbeam 132. At least one moving crossbeam 144 extends into and slides with the corresponding at least one middle crossbeam 135, thereby enabling the extension frame 14 as a whole to extend, retract, and collapse relative to the fixed frame 13. The internal cavity of the upper moving beam 141 is connected to the internal cavity of the upper crossbeam 131, and / or the internal cavity of the lower moving beam 142 is connected to the internal cavity of the lower crossbeam 132, and / or the internal cavity of at least one moving crossbeam 144 is selectively connected to the internal cavity of the corresponding middle crossbeam 135. In actual use, the moving crossbeams 144 and the middle crossbeam 135 can be selectively set to be water-filled depending on the installation of the nozzles 2. Water is generally circulated in the upper crossbeam 131 and the lower crossbeam 132. The upper crossbeam 131 is generally equipped with at least one downward spray nozzle 2, and the lower crossbeam 132 is usually also selected to be water-filled due to the swingable spray pipe 6 mentioned below. In addition, a handle 20 is usually provided on the moving column 143, through which the extension frame 14 can be pulled to extend or retract.

[0039] To ensure that the fixing frames 13 of the first partition plate 11 are connected as a whole to form a cuboid frame, the extension frame 14 is only one stage. More preferably, the fixing frames 13 of the first partition plate 11 are connected to the fixing frames 13 of the second partition plate 12 via three connecting rods 4. The three connecting rods 4 are the first connecting rod 41, the second connecting rod 42, and the third connecting rod 43. The top end of the fixing frames 13 of the first partition plate 11 is hinged to the top end of the fixing frames 13 of the second partition plate 12 via the first connecting rod 41. The top end of the fixing frame 13 of the first partition plate 11 is hinged to the top end of the fixing frame 13 of the second partition plate 12 via the second connecting rod 42. 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 partition plate 11 is hinged to the bottom end of the fixing frame 13 of the second partition plate 12 via 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 enables the movement... The mobile vehicle fire suppression system comprises a rectangular frame with a notch. The extension frame 14 of the first isolation plate 11 is connected to the extension frame 14 of the second isolation plate 12 via a fourth connecting rod 44 and a detachable connecting rod 45. The top end of the extension frame 14 of the first isolation plate 11 is hinged to the top end of the extension frame 14 of the second isolation plate 12 via the fourth connecting rod 44. Specifically, the top end of the extension frame 14 is one end of the upward moving beam 141. The bottom end of the extension frame 14 of the first isolation plate 11 is connected to the second isolation plate 12 via the detachable connecting rod 45. The bottom end of the extension frame 14 of the plate 12 is detachably connected. Specifically, the bottom end of the extension frame 14 is one end of the lower 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 that match 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. The detachable connection of the detachable connecting rod 45 is achieved by the insertion or snapping of the pins or slots with the two sleeves.Further preferably, in order to achieve the overall unfolding or folding of the cuboid frame, each of the first connecting rods 41 is provided with a first hinge 411 for folding in the middle, and the first connecting rod 41 bends toward the second connecting rod 42. Each of the second connecting rods 42 is provided with a second hinge 421 for folding in the middle, and the second connecting rod 42 bends toward the first connecting rod 41. Each of the third connecting rods 43 is provided with a third hinge 431 for folding in the middle, and the third connecting rod 43 bends toward the detachable connecting rod 45. Each of the fourth connecting rods 44 is provided with a fourth hinge 441 for folding in the middle, and the fourth connecting rod 44 bends toward the second connecting rod 42. When the first partition plate 11 and the second partition plate 12 are to be brought together, the detachable connecting rod is first disassembled. The first connecting rod 41 is folded towards the second connecting rod 42, the second connecting rod 42 is folded towards the first connecting rod 41, the third connecting rod 43 is folded towards the detachable connecting rod 45, and the fourth connecting rod 44 is folded towards the second connecting rod 42. Then the first isolation plate 11 and the second isolation plate 12 are brought together to achieve overall folding. When the first isolation plate 11 and the second isolation plate 12 need to be unfolded, the first isolation plate 11 and the second isolation plate 12 are pulled, and the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 are gradually unfolded until all four connecting rods are straight. Then the detachable connecting rod 45 is installed to form an unfolded cuboid frame. The above scheme can realize the overall unfolding and folding of the mobile car fire-fighting device.

[0040] To enable the mobile vehicle fire suppression system to spray water for fire extinguishing, the fixed frame 13 is further equipped with one or more nozzles 2 and / or the extension frame 14 is equipped with one or more nozzles 2. Specifically, the upper crossbeam 131 of the fixed frame 13 is equipped with two nozzles 2, which are symmetrically distributed. The middle crossbeam 135 is equipped with one nozzle 2, the upper moving beam 141 is equipped with one nozzle 2, and the moving crossbeam 144 is equipped with one nozzle 2. By setting the above five nozzles 2, water can be effectively sprayed on the front and sides of the new energy vehicle, effectively covering most or all of the fire-prone parts of the new energy vehicle. Since both the first isolation plate 11 and the second isolation plate 12 can include the fixed frame 13 and the extension frame 14, that is, the two isolation plates are usually equipped with 10 nozzles 2. The 10 nozzles 2 spray a large amount of water at the same time to extinguish the fire in time, which greatly improves the fire extinguishing capability of the mobile vehicle fire suppression system.
