[0039] Embodiment one: please refer to Figures 1-5 The present application 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 the 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, screw connection) with fire-fighting quick connector 12.

[0040] In some embodiments, the connecting assembly 2 comprises: a flow pipeline 1 21, a flow pipeline 2 22, and a flexible hose 23, both ends of the flexible hose 23 are fixedly connected or rotatably connected with the flow pipeline 1 21 and the flow pipeline 2 22 respectively, the side of the flow pipeline 1 21 and the flow pipeline 2 22 is provided with a connecting piece 24, the connecting piece 24 is slidably connected with the flow pipeline 1 21 and the flow pipeline 2 22 respectively, the connecting piece 24 on the side of the flow pipeline 1 21 is slidably connected with the fire extinguishing assembly 1 1, and the connecting piece 24 on the side of the flow pipeline 2 22 is slidably connected with the fire extinguishing assembly 3. That is, the flow pipeline 1 21 and the flow pipeline 2 22 are respectively connected with the fire extinguishing assembly 1 1 and the fire extinguishing assembly 3 through a connecting piece 24 respectively, and the length adjustment can be realized by sliding the length of the connecting piece 24 into the fire extinguishing assembly 1 1 and the fire extinguishing assembly 3. Specifically, a buckle can be arranged at the free end of the connecting piece 24, a corresponding sliding groove can be arranged on the inner wall of the side pipeline 001 of the fire extinguishing assembly 1 or the fire extinguishing assembly 3, and a clamping groove matched with the buckle can be arranged at different positions in the sliding groove, so that when the buckle is matched with the clamping groove, the connecting piece 24 can be locked with the corresponding side pipeline. Of course, a sealing ring or the like can also be arranged between the connecting piece 24 and the side pipeline.

[0041] In some embodiments, the spraying assembly 5 on the shunt pipeline 4 in the connecting assembly 2 comprises 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, and a plurality of spraying heads 54 (preferably 5) are arranged at intervals on each multi-stage dispersion head 53, each spraying head 54 comprises a semicircular or arc-shaped spraying surface in longitudinal section, and a plurality of spraying holes are uniformly arranged on the spraying surface, so that the spraying range of each spraying head 54 is 83°-120°. In fact, the spraying head 54 sprays a water column, and the spraying 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 .

[0042] For example, when the vehicle is on fire, the device is unfolded, and according to the length of the vehicle chassis, because the connecting assembly 2 is movably connected with the fire extinguishing assembly 1 1 and the fire extinguishing assembly 3, the connecting assembly 2 and the fire extinguishing assembly 3 are stretched to a 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 that the water flow flows in the device.

[0043] The purpose is to make the total length of the fire extinguishing assembly 1 1, the connecting assembly 2 and the fire extinguishing assembly 3 more suitable for the vehicle, to provide convenience for subsequent fire extinguishing, and also to adapt to vehicles of various lengths, to provide protection for rescue operations.

[0044] 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 subjected to water leakage treatment, so as not to appear the situation of water leakage, so as to maximize the utilization of water flow and maximize the guarantee of the efficiency of fire extinguishing. The treatment mode of the connection is not specifically described here.

[0045] Please refer to Figure 3 and Figures 4A-4B As shown in the figure, the inside of the fire extinguishing assembly one 1, the connecting assembly 2 and the fire extinguishing assembly two 3 is fixedly connected with the shunt pipeline 4, the inside of the connecting assembly 2 is fixedly connected with two shunt pipelines 4, the two shunt pipelines 4 are respectively in the middle of the flow-through pipeline one 21 and the flow-through 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 on the opposite faces of the side of the fire extinguishing assembly one 1 and the fire extinguishing assembly two 3 respectively, and the spraying assembly 5 is fixedly connected on the two sides of the shunt pipeline 4.

[0046] In some embodiments, the spraying assembly 5 comprises 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. Among them, the adjusting head 52 comprises 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 respectively to adapt to different heights or / and different lengths of the chassis. Considering that if it is a fire-fighting tool as a fire station, it is necessary to consider the matching of different heights and different lengths of different vehicle chassis. Therefore, on the one hand, the length is adjusted by movably connecting the fire extinguishing assembly and the connecting assembly, and on the other hand, the spraying assembly with the width adjusting piece and the height adjusting piece is set, so that the chassis of different vehicles can be matched as much as possible.

[0047] Specifically, referring to Figure 4A The height of each spraying head can be adjusted by the height adjusting piece 522, so as to adjust the height of the intersection O1 between the spraying ranges of the adjacent two spraying heads, for example, from H1 to H2, so that all vehicle chassis whose height is between H1 and H2 can be covered in the width direction, avoiding the situation that part of the chassis cannot be covered because the chassis is too low, for example, the chassis is below the position of H1.

[0048] Similarly, referring to Figure 4BThe width adjustment member 521 can be used to adjust the distance between each sprinkler head and the diversion pipe, that is, to adjust the spacing between each row of sprinkler heads, that is, to adjust the height of the intersection point O2 between the spraying widths of two adjacent rows of sprinkler heads, for example, from H1 to H2. This ensures that all vehicle chassis with a height between H1 and H2 are covered in the longitudinal direction by the spraying width, avoiding the situation where a lower chassis, for example, below H1, results in partial coverage. In particular, when the connector is used to adjust the distance between the first and second fire extinguishing components and the connecting component, and when the movable hose is expanded under the action of water pressure, the spacing between the sprinkler heads in each row varies. Therefore, the adjustment head 52 can be used to minimize the negative effects of this difference, such as the possibility of some local areas being uncovered.

[0049] Exemplarily, by pushing the adjusting head 52 inward, the spraying can cover the main line surface according to the line layout of the vehicle chassis to avoid emergency accidents. The multi-stage dispersion head 53 is pulled upward according to the chassis height of the vehicle, so that the device can be smoothly moved to the bottom of the vehicle and put out the fire. The surface of the spray head 54 is provided with holes to facilitate the dispersion of water flow. The layout of the diversion pipe 4 can make the device cover the vehicle chassis more comprehensive.

[0050] The purpose is to spray all sides of the bottom of the vehicle, extinguish the fire as soon as possible, ensure the safety of the staff to the greatest extent, and avoid the burning of the vehicle, so as to analyze the problems caused by the accident, summarize the experience, and avoid the waste of automobile resources.

[0051] It should be noted that the connection between the regulating head 52 and the spray pipe 51 and the multi-stage dispersion head 53 has been treated for leakage, and no leakage will occur. The leakage treatment method will not be elaborated in detail here. The positional relationship of the multi-stage dispersion head 53 is not fixed and depends on the specific situation. It will not be elaborated in detail here. This embodiment takes the pipe bodies on both sides at the maximum length and the horizontal pipe of the nozzle at the maximum length as an example.

[0052] In some embodiments, a diversion pipe 4 is set up, with both ends respectively connected to the interior of fire extinguishing component 1, connecting component 2 and fire extinguishing component 2 3, to change the flow direction of the internal water, and a spraying component 5 is set on the diversion pipe 4 to achieve large-scale spraying.

[0053] In some embodiments, the components of the connecting assembly 2 are respectively flow pipe 1 21, flow pipe 2 22 and flexible hose 23, the two ends of the flexible hose 23 are respectively fixedly connected with the flow pipe 1 21 and the flow pipe 2 22, the side surfaces of the flow pipe 1 21 and the flow pipe 2 22 are respectively provided with connecting pieces 24, the connecting pieces 24 are respectively in sliding connection with the flow pipe 1 21 and the flow pipe 2 22, the connecting piece 24 on the side surface of the flow pipe 1 21 is in sliding connection with the fire extinguishing assembly 1, and the connecting piece 24 on the side surface of the flow pipe 2 22 is in sliding connection with the fire extinguishing assembly 2 3.

[0054] Referring to Figure 5 The fire extinguishing assembly 1 and the fire extinguishing assembly 2 3 are moved towards the middle, so as to fold the flexible hose 23 by bending, so that the fire extinguishing assembly 2 3 is turned over above the fire extinguishing assembly 1, and the spraying assembly 5 is folded into a compact state, so as to facilitate transportation and storage; when it is needed to use, the fire extinguishing assembly 2 3 is only needed to be turned over and pushed to the bottom of the vehicle chassis. Of course, after unfolding, the connecting pieces and the adjusting heads can be adjusted to adapt to vehicle chassis of different lengths or different widths. That is to say, in the embodiment, the components are connected as a whole, rather than being scattered parts, so that on-site assembly is not needed, and only unfolding is needed on site.

[0055] The purpose is that since the flexible hose 23 can be bent, the fire extinguishing assembly 2 3 can be bent to cover above the fire extinguishing assembly 1 after folding the device, which makes it more convenient for rescue personnel to take, saves the overall floor area of the device, facilitates storage, and makes it simpler to lay for subsequent use.

[0056] It should be noted that the material of the spraying assembly 5 is a special material that can withstand fire, and 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, which is determined according to specific conditions and is not specifically described here.

[0057] Working principle: for the folded device, after turning over the fire extinguishing assembly 2 3, the fire extinguishing assembly 1 and the fire extinguishing assembly 2 3 are stretched to lay the device, and according to the layout of the vehicle chassis and the height of the vehicle chassis, the adjusting head 52 and the multi-stage dispersion head 53 and the connecting piece 24 are adjusted, and then 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 it is folded and recycled.

[0058] Embodiment two: referring to Figures 6-7The 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 assembly no. 1 and fire extinguishing assembly 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 connecting piece 24 telescopic. Specifically, the connecting component 2 includes: two flow pipeline threes 200 that are symmetrically arranged, two ends of flow pipeline three 200 are connected with the side pipe 001 of fire extinguishing assembly no. 1 and fire extinguishing assembly two 3 respectively through a connecting piece 24 sliding, 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, set two spray assemblies) are arranged on each shunt pipe 4 both sides respectively along its length extension direction interval.

[0059] Different from above-mentioned embodiment one, the spray assembly includes: spray pipe 51, adjusting head 52, multistage dispersion head 53 and spray head 54, the inlet end of adjusting head 52 is communicated with spray pipe 51, the outlet end is communicated with the inlet end of hierarchical dispersion head 53, and a plurality of spray heads 54 are arranged on each multistage dispersion head 53 interval, wherein each spray head includes semicircular or longitudinal section arc-shaped spray face, a plurality of spray holes are uniformly arranged on the spray face, 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 one-piece forming process.

[0060] Of course, in another embodiment, the adjusting head 52 can also be connected with spray pipe 51 sliding, so that the spacing between spray head and shunt pipe or bottom pipe 002 can be adjusted. Of course, the adjusting head of above-mentioned embodiment one can also be used to realize the adjustment of width or height to adapt to the vehicle chassis of different length and different height.

[0061] In some embodiments, the diversion pipe 4, circulation pipe 3 200, fire extinguishing assembly 1, and fire extinguishing assembly 2 3 in the fire extinguishing device are all made of flexible plastic materials, while the connector 24 is made of non-flexible material. Therefore, elastic sealing rings that can slide on the connector 24 can be provided at the end of the side pipe 001 that connects to the connector 24 and at the end of the circulation pipe 3 200 that connects to the connector. The diameter of the circulation pipe 3 200 gradually increases from the middle to the ends, allowing the sealing ring to slide on the connector. When it slides to a certain position, it no longer slides (of course, corresponding limiting rings can also be provided at the end of the connector to limit the sealing ring). Therefore, the pipeline connection and sealing can be achieved through friction. It is precisely because of the use of friction to achieve sealing that, after adjusting the position, the fire extinguishing device can be used only as an emergency disposable and is more convenient to store than the fire extinguishing devices in the above embodiments. Considering that car owners carry a fire extinguishing device as a one-time emergency device and may not use it for a long time, its storageability needs to be considered. It is hoped that it will take up as little space as possible while being able to be quickly deployed to extinguish a fire. Therefore, it is considered here that most components are made of flexible materials.

[0062] Of course, in other embodiments, the fire extinguishing device of the above embodiment can also be made of disposable consumables, such as flexible high-temperature resistant materials, as a disposable fire extinguishing device.

[0063] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0064] Through the description of the above embodiments, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus the necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better embodiment. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, 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 number of instructions for enabling a computer terminal (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.

[0065] 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.
