[0040] Embodiment one: please refer to Figures 1-5The utility model provides a kind of adjustable vehicle chassis fire extinguishing device. Specifically, it includes fire extinguishing component one 1, connecting component 2 and fire extinguishing component two 3, connecting component 2 is respectively connected with fire extinguishing component one 1 and fire extinguishing component two 3 (for example, telescopic connection, or other adjustable two between connecting part length of active connection mode), wherein, fire extinguishing component one 1, connecting component 2 and fire extinguishing component two 3 all are provided with shunt pipeline 4, and fire extinguishing component one 1, fire extinguishing component two 3 and shunt pipeline 4 are all provided with spray assembly 5, the side surface of fire extinguishing component one 1 is fixedly connected with water inlet pipe 11, and the end of water inlet pipe 11 away from fire extinguishing component one 1 is movably connected (for example threaded connection) with fire-fighting quick connector 12.

[0041] In some embodiments, the connecting component 2 includes: flow pipeline one 21, flow pipeline two 22 and flexible hose 23, both ends of the flexible hose 23 are respectively fixedly connected or rotatably connected with the flow pipeline one 21 and the flow pipeline two 22, the side surfaces of the flow pipeline one 21 and the flow pipeline two 22 are both provided with connecting pieces 24, the connecting pieces 24 are respectively slidably connected with the flow pipeline one 21 and the flow pipeline two 22, the connecting piece 24 on the side surface of the flow pipeline one 21 is slidably connected with the fire extinguishing component one 1, and the connecting piece 24 on the side surface of the flow pipeline two 22 is slidably connected with the fire extinguishing component two 3. That is, the flow pipeline one 21 and the flow pipeline two 22 are respectively connected with the fire extinguishing component one 1 and the fire extinguishing component two 3 through a connecting piece 24, and the length adjustment can be realized by sliding the length of the connecting piece 24 into the fire extinguishing component one 1 and the fire extinguishing component two 3. Specifically, buckles can be arranged on the free ends of the connecting pieces 24, corresponding sliding grooves can be arranged in the inner walls of the side pipes of the fire extinguishing component one 1 or the fire extinguishing component two 3, and clamping grooves matched with the buckles can be arranged at different positions in the sliding grooves, so that the connecting pieces 24 can be locked with the corresponding side pipes when the buckles are matched with the clamping grooves. Of course, sealing rings or the like can also be arranged between the connecting pieces 24 and the side pipes.

[0042] In some embodiments, the spray assembly 5 on the shunt pipeline 4 in the connecting component 2 includes a spray pipe 51, an adjusting head 52, a multi-stage dispersion head 53 and a spray head 54, the adjusting head 52 is movably connected with the spray pipe 51 on the side surface of the spray pipe 51, and a plurality of spray heads 54 (preferably 5) are arranged at intervals on each multi-stage dispersion head 53, each spray head 54 includes a semicircular or arc-shaped spray surface in longitudinal section, and a plurality of spray holes are uniformly arranged on the spray surface, so that the spray range of each spray head 54 is 83°-120°. In fact, the spray head 54 sprays water column, and the spray range here includes the angle formed by the longitudinal section of the water column obtained by longitudinally cutting the water column along the height direction, as shown in Figure 4A And Figure 4B .

[0043] For example, when the vehicle is on fire, the device is spread out, and according to the length of the vehicle chassis, because the connecting assembly 2 is movably connected with the fire extinguishing assembly one 1 and the fire extinguishing assembly two 3, the connecting assembly 2 and the fire extinguishing assembly two 3 are stretched to the length close to the vehicle, and then pushed to the bottom of the vehicle, and finally embedded with the fire hydrant through the fire quick connector 12. The fire quick connector 12 can guide the water flow, so as to make the water flow in the device.

[0044] The purpose is to make the total length of the fire extinguishing assembly one 1, the connecting assembly 2 and the fire extinguishing assembly two 3 more suitable for the vehicle, to facilitate subsequent fire extinguishing, and also to adapt to vehicles of various lengths, to provide protection for rescue operations.

[0045] It should be noted that the connection between the connecting piece 24 and the fire extinguishing assembly one 1, the connecting assembly 2 and the fire extinguishing assembly two 3 is treated to prevent water leakage, so that the water flow is maximized and the efficiency of fire extinguishing is maximized. The treatment method of the connection is not specifically described here.

[0046] Please refer to Figure 3 and Figures 4A-4B As shown in the drawings, the fire extinguishing assembly one 1, the connecting assembly 2 and the fire extinguishing assembly two 3 are fixedly connected with the shunt pipeline 4 inside, the connecting assembly 2 is fixedly connected with two shunt pipelines 4 inside, and the two shunt pipelines 4 are respectively in the middle of the flow pipeline one 21 and the flow pipeline two 22. The shunt pipeline 4 is in communication with the fire extinguishing assembly one 1, the connecting assembly 2 and the fire extinguishing assembly two 3, the spraying assembly 5 is fixedly connected to the opposite faces of the side faces of the fire extinguishing assembly one 1 and the fire extinguishing assembly two 3, and the spraying assembly 5 is fixedly connected to the two sides of the shunt pipeline 4.

[0047] In some embodiments, the spraying assembly 5 includes a spraying pipe 51, an adjusting head 52, a multi-stage dispersion head 53 and a spraying head 54. The adjusting head 52 is movably connected with the spraying pipe 51 on the side of the spraying pipe 51, the multi-stage dispersion head 53 is movably connected with the adjusting head 52 above the adjusting head 52, and the spraying head 54 is fixedly connected with the multi-stage dispersion head 53. The adjusting head 52 includes a width adjusting piece 521 movably connected with the spraying pipe 51, and a height adjusting piece 522 fixedly connected with the multi-stage dispersion head 53 and movably connected with the width adjusting piece 521, so that the width adjusting piece 521 and the height adjusting piece 522 can be adjusted to adapt to different heights or / and different lengths of the chassis. Considering that if it is a fire-fighting tool of a fire station, it is necessary to consider the matching of different vehicle chassis heights and lengths, therefore, on the one hand, the length is adjusted by movably connecting the fire extinguishing assembly with the connecting assembly, and on the other hand, the spraying assembly with the width adjusting piece and the height adjusting piece is provided, so that the chassis of different vehicles can be adapted as much as possible.

[0048] Specifically, refer toFigure 4A The height of each spray head can be adjusted by the height adjusting member 522, so as to adjust the height of the intersection O1 between the spray ranges of two adjacent spray heads, for example, from H1 to H2, so that all the vehicle chassis with the height between H1 and H2 can be covered by the spray range in the width direction, and the situation that part of the vehicle chassis cannot be covered due to the low chassis, for example, the chassis below H1, can be avoided.

[0049] Similarly, referring to Figure 4B The distance between each spray head and the shunt pipe, i.e., the distance between each row of spray heads, i.e., the height of the intersection O2 between the spray ranges of two adjacent rows of spray heads, can be adjusted by the width adjusting member 521, for example, from H1 to H2, so that all the vehicle chassis with the height between H1 and H2 can be covered by the spray range in the length direction, and the situation that part of the vehicle chassis cannot be covered due to the low chassis, for example, the chassis below H1, can be avoided. In particular, when the connecting member is used to adjust the distance between the first and second fire extinguishing assemblies and the connecting assembly, and the active hose is stretched under the water pressure, the distance between each row of spray heads is different, and therefore, the negative effects caused by the difference, for example, the situation that some local areas cannot be covered, can be reduced by the adjusting head 52.

[0050] For example, by pushing the adjusting head 52 inward, the spray can cover the main line surface according to the line layout of the vehicle chassis, and the emergency situation can be avoided. By pulling the multi-stage dispersion head 53 upward, the device can be smoothly moved to the bottom of the vehicle according to the height of the vehicle chassis, and the vehicle can be extinguished. The surface of the spray head 54 is provided with holes for the dispersion of water flow, and the layout of the shunt pipe 4 can make the device cover the vehicle chassis more comprehensively.

[0051] The purpose is to spray the vehicle chassis comprehensively, extinguish the fire as soon as possible, maximize the safety of the staff, avoid the burning of the vehicle, analyze the problems of the accident, summarize the experience, and avoid the waste of vehicle resources.

[0052] It should be noted that the connection between the adjusting head 52 and the spray pipe 51 and the multi-stage dispersion head 53 is water leakage treated, and water leakage will not occur. The water leakage treatment method is not specifically described here. The position relationship of the multi-stage dispersion head 53 is not fixed, but depends on the specific situation, which is not specifically described here. The embodiment takes the case that the two side pipe bodies are at the maximum length, and the spray head horizontal pipe is also at the maximum length as an example.

[0053] In some embodiments, by setting the shunt pipe 4, which is connected to the inside of the fire extinguishing assembly one 1, the connecting assembly 2 and the fire extinguishing assembly two 3 respectively, changing the flow direction of the internal water, and setting the spraying assembly 5 on the shunt pipe 4, a large range of spraying can be achieved.

[0054] In some embodiments, the connecting assembly 2 is composed of flow pipe one 21, flow pipe two 22 and flexible hose 23. The two ends of the flexible hose 23 are fixedly connected with the flow pipe one 21 and the flow pipe two 22 respectively. The side of the flow pipe one 21 and the flow pipe two 22 is provided with a connecting piece 24, which is slidingly connected with the flow pipe one 21 and the flow pipe two 22 respectively. The connecting piece 24 on the side of the flow pipe one 21 is slidingly connected with the fire extinguishing assembly one 1, and the connecting piece 24 on the side of the flow pipe two 22 is slidingly connected with the fire extinguishing assembly two 3.

[0055] Referring to Figure 5 The fire extinguishing assembly one 1 and the fire extinguishing assembly two 3 are moved towards the middle, so that the folded flexible hose 23 is folded, the fire extinguishing assembly two 3 is turned over to the top of the fire extinguishing assembly one 1, and the spraying assembly 5 is folded to a compact state, so as to facilitate transportation and storage. When it is needed to use, the fire extinguishing assembly two 3 is only needed to be turned over and pushed to the bottom of the vehicle chassis. Of course, after unfolding, the connecting piece and the adjusting head can be adjusted to adapt to the vehicle chassis of different lengths or different widths. That is to say, in this embodiment, each component is connected as a whole, rather than being scattered parts, so that on-site assembly is not needed, and only unfolding is needed on site.

[0056] The purpose is that since the flexible hose 23 can be bent, the fire extinguishing assembly two 3 can be bent to cover the fire extinguishing assembly one 1, the device can be folded, the rescue personnel can take it more conveniently, the overall area occupied by the device is saved, storage is facilitated, and laying is also simpler for subsequent use.

[0057] It should be noted that the material of the spraying assembly 5 is special material, which can withstand fire. The material selection is diversified, and the flexible hose 23 is made of high-temperature resistant material and automatically stretches under high-pressure water flow. The specific conditions are determined according to the specific conditions, which are not described here.

[0058] Working principle: for the folded device, after turning over the fire extinguishing assembly two 3, the fire extinguishing assembly one 1 and the fire extinguishing assembly two 3 are stretched to lay the device, the adjusting head 52 and the multi-stage dispersion head 53, the connecting piece 24 are adjusted according to the layout of the vehicle chassis and the height of the vehicle chassis, the whole device is pushed to the vehicle chassis, then the fire hydrant connector 12 is connected with the fire hydrant, the chassis is sprayed, and the fire source is extinguished. After use, the connection with the fire hydrant is disconnected, the water of the device is emptied, and then the device is folded and recycled.

[0059] Embodiment two: refer to Figures 6-7 The utility model also provides another vehicle chassis fire extinguishing device, it includes each component of above -mentioned embodiment, different, the connecting component 2 between fire extinguishing component one 1 and fire extinguishing component two 3 in this embodiment is not the scheme of movable hose 23, but is the flow pipeline three 200 that can be connected with the telescopic connection of connecting piece 24. Specifically, the connecting component 2 includes: two flow pipeline threes 200 that are symmetrically arranged, both ends of flow pipeline three 200 are slidably connected with the side pipe 001 of fire extinguishing component one 1 and fire extinguishing component two 3 respectively through a connecting piece 24, and two flow pipeline threes 200 that are symmetrically arranged are communicated through at least two shunt pipes 4, and at least two spray assemblies 5 (preferably, two spray assemblies are arranged) are arranged on each shunt pipe 4 both sides respectively along its length extension direction interval.

[0060] Different from the above-mentioned embodiment one, the spray assembly includes: a spray pipe 51, an adjusting head 52, a multi-stage dispersion head 53 and a spray head 54, the inlet end of the adjusting head 52 is communicated with the spray pipe 51, the outlet end is communicated with the inlet end of the multi-stage dispersion head 53, and a plurality of spray heads 54 are arranged on each multi-stage dispersion head 53, wherein each spray head includes a semicircular or arc-shaped spray surface in longitudinal section, a plurality of spray holes are uniformly arranged on the spray surface, so that the spray range of each spray head 54 is 83°-120° (preferably, the spray range is 105°). Preferably, the adjusting head 52 is formed by an integral molding process.

[0061] Of course, in other embodiments, the adjusting head 52 can also be slidably connected with the spray pipe 51, so that the distance between the spray head and the shunt pipe or the bottom pipe 002 can be adjusted. Of course, the adjusting head of the above-mentioned embodiment one can also be used to realize the adjustment of width or height to adapt to vehicle chassis of different lengths and different heights.

[0062] In some embodiments, the shunt pipe 4, the flow pipe three 200, the fire extinguishing assembly one 1 and the fire extinguishing assembly two 3 in the fire extinguishing device are made of flexible plastic material, and the connecting piece 24 is made of non-flexible material. Therefore, the elastic sealing ring that can slide on the connecting piece 24 can be arranged on the end of the side pipe 001 that is opposite to the connecting piece 24 and the end of the flow pipe three 200 that is connected with the connecting piece. The pipe diameter of the flow pipe three 200 gradually increases from the middle to the two ends in the extension direction. Therefore, the sealing ring can slide on the connecting piece, and when it slides to a certain position, it can no longer slide (of course, a limiting ring can be arranged at the end of the connecting piece to limit the sealing ring). Therefore, the pipe connection and sealing can be achieved by friction. Because the sealing is achieved by friction, after adjusting the position, the fire extinguishing device is only used once as an emergency, and compared with the fire extinguishing device in the above embodiment, it is more convenient to store. Because it is considered that the owner will carry the fire extinguishing device required for one-time emergency, and it may not be used for a long time, it is necessary to consider its storage property, and it is expected that it can occupy as little space as possible while being quickly unfolded for fire extinguishing. Therefore, it is considered that most of the components are made of flexible material.

[0063] Of course, in other embodiments, the fire extinguishing device of the first embodiment can also use disposable consumables, such as flexible high-temperature-resistant materials, as a one-time use fire extinguishing device.

[0064] It should be noted that in this document, the terms "comprising", "including", or any other variant thereof are intended to cover non-exclusive inclusions, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such a process, method, article or device. Without more limitations, the element defined by the statement "including a" does not exclude the presence of another identical element in the process, method, article or device including the element.

[0065] From the description of the above embodiments, those skilled in the art can clearly understand that the above-mentioned embodiment method can be realized by means of software and a general hardware platform as required. Of course, it can also be realized by hardware, but in many cases, the former is a better embodiment. Based on such understanding, the technical solution of the present application can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a plurality of instructions for making a computer terminal (which can be a mobile phone, computer, server, or network device, etc.) execute the method described in each embodiment of the present application.

[0066] The embodiments of the present application are described above with reference to the drawings; however, the present application is not limited to the specific embodiments described above, but the specific embodiments described above are merely illustrative rather than restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims, and these all belong to the protection of the present application.
