Technical Field
[0001] The utility model relates to the technical field of fire trucks, and more specifically, to a fire cannon pipeline structure and a fire truck. Background Art
[0002] A fire truck, also known as a fire engine, is a vehicle designed and manufactured according to needs to be suitable for firefighters to ride in, equipped with various fire-fighting equipment or fire extinguishing agents, and used by fire departments for fire extinguishing, auxiliary fire extinguishing or fire rescue. Fire departments in most countries, including China, also use it for other emergency rescue purposes. A fire truck can transport firefighters to the disaster site and provide them with a variety of tools for carrying out rescue tasks.
[0003] In the prior art, the connecting pipe of the fire cannon on the fire truck directly passes through the tank body and then is connected to the pump body. However, when the fire cannon or the pipeline is damaged, it is difficult to replace and maintain the pipeline, resulting in a high maintenance cost of the pipeline. Summary of the Utility Model
[0004] The technical problem solved by the utility model is the problem that the high maintenance difficulty of the pipeline connected to the fire cannon in the prior art leads to a high maintenance cost.
[0005] The embodiments of the utility model can be implemented as follows:
[0006] The utility model provides a fire cannon pipeline structure, including:
[0007] A fire tank with an accommodation space inside;
[0008] A conduction pipe arranged inside the accommodation space; both ends of the conduction pipe are provided with fittings, and the fittings are arranged inside the fire tank;
[0009] Two transition pieces are both arranged outside the fire tank; the two transition pieces correspond to the two fittings respectively, and are fixedly connected to the fittings through connectors passing through the transition pieces and the fire tank;
[0010] A fire cannon is arranged outside the fire tank and is detachably connected to one of the transition pieces, and the fire cannon is communicated with the conduction pipe.
[0011] The beneficial effects of the fire cannon pipeline structure provided by the utility model compared with the prior art include:
[0012] In this fire cannon pipeline structure, the conduction pipe is arranged in a way that is independent of the fire cannon. In the case where the conduction pipe needs to be maintained, the fire cannon can be removed from the transition piece, and then the conduction pipe can be independently removed from the fire tank, thus enabling the maintenance or replacement of the conduction pipe, reducing the maintenance difficulty of the conduction pipe, and further reducing the maintenance cost. On the other hand, since the conduction pipe is arranged inside the fire tank, the overall occupied volume of the fire cannon pipeline structure can be reduced, preventing complicated problems caused by the pipeline.
[0013] Optionally, blind hole mounting holes are provided on the fitting, and the connecting piece is fitted with the blind hole mounting holes.
[0014] By providing blind hole mounting holes on the fitting, when the fitting is attached to the inner wall of the fire tank, the blind hole mounting holes can be sealed, thus avoiding the leakage of the liquid inside the fire tank and improving the sealing performance of the fire tank.
[0015] Optionally, the blind hole mounting holes are threaded holes.
[0016] Optionally, the connecting piece is a bolt.
[0017] Optionally, a first sealing gasket is provided between the fitting and the fire tank.
[0018] Through the provision of the first sealing gasket, the sealing effect between the fitting and the fire tank can be further improved, thereby preventing the leakage of the liquid inside the fire tank.
[0019] Optionally, a second sealing gasket is provided between the transition piece and the fire tank.
[0020] By providing a second sealing gasket between the transition piece and the fire tank, the sealing performance of the fire tank can be further improved, thereby preventing the leakage of the liquid inside the fire tank.
[0021] Optionally, the conduction pipe and the fitting are integrally formed.
[0022] Optionally, a stepped hole is further provided on the side of the transition piece away from the fire tank, and the connecting piece passes through the stepped hole to connect with the fitting, and the connecting piece is accommodated inside the stepped hole.
[0023] After the transition piece and the fitting are assembled, the connecting piece is accommodated inside the stepped hole, preventing the connecting piece from occupying a part of the outer surface area of the transition piece and facilitating the connection between the fire cannon and the transition piece.
[0024] Optionally, the conducting pipe includes a first conducting section, a second conducting section, and a third conducting section. The first conducting section is disposed at one end close to the fire monitor, and the second conducting section is disposed between the first conducting section and the third conducting section. An arc transition section is provided between the first conducting section and the second conducting section, and another arc transition section is provided between the second conducting section and the third conducting section, and an obtuse angle is formed between the first conducting section and the second conducting section.
[0025] Providing an arc transition section between the first conducting section and the second conducting section, and an arc transition section between the second conducting section and the first conducting section can reduce the impact force of the high-pressure liquid on the peripheral wall of the conducting pipe, thereby reducing the probability of damage to the conducting pipe. Further setting an obtuse angle between the first conducting section and the second conducting section can further reduce the impact force of the high-pressure liquid on the inner wall of the conducting pipe and reduce the probability of damage to the conducting pipe.
[0026] A fire truck includes the above-mentioned fire monitor pipeline structure.
[0027] The fire truck provided by the present utility model adopts the above-mentioned fire monitor pipeline structure.

[0038] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.
[0039] Please refer to Figure 1 , in the embodiments of the present application, a fire monitor pipeline structure 10 is provided. The fire monitor pipeline structure 10 can be applied to a fire truck for fire fighting operations. Among them, the fire monitor pipeline structure 10 can improve the problem of high maintenance difficulty and high maintenance cost of the pipeline connected to the fire monitor 500 in the prior art.
[0040] In this embodiment, please refer to Figure 1 and Figure 2, the fire cannon pipeline structure 10 includes a fire tank 100, a conduction pipe 200, a fire cannon 500, and two transition pieces 300. A receiving space 110 is provided inside the fire tank 100, and the receiving space 110 can be used to hold liquids for fire fighting, such as water or fire-fighting foam. The conduction pipe 200 is arranged inside the receiving space 110; fitting parts 210 are provided at both ends of the conduction pipe 200, and the fitting parts 210 are arranged inside the fire tank 100. Optionally, the conduction pipe 200 is made of a steel pipe. The two transition pieces 300 are both arranged outside the fire tank 100; the two transition pieces 300 respectively correspond to the two fitting parts 210, and are fixedly connected to the fitting parts 210 through connecting pieces 400 that penetrate through the transition pieces 300 and the fire tank 100.
[0041] It should be noted that through holes are provided at positions on the fire tank 100 corresponding to both ends of the conduction pipe 200 to facilitate the connection of the conduction pipe 200 to other components outside. The fire cannon 500 is arranged outside the fire tank 100 and is detachably connected to one of the transition pieces 300, and the fire cannon 500 is communicated with the conduction pipe 200; among them, when the fire cannon 500 is connected to one of the transition pieces 300, the conduction pipe 200 is connected to the fire cannon 500 through the through hole on the fire tank 100, and the conduction pipe 200 can guide the liquid to the fire cannon 500. It should be noted that a pump for extracting the liquid inside the fire tank 100 is generally provided in a fire truck, and the pump is connected to the receiving space 110 through a pipe to facilitate the extraction of the liquid inside the fire tank 100. And, the pump is connected to the other end of the conduction pipe 200, that is, the pump is connected to the transition piece 300 corresponding to the other end of the conduction pipe 200 to achieve the connection between the pump and the conduction pipe 200. Based on this, the pump can extract the liquid inside the fire tank 100 and guide it to the fire cannon 500, and the fire cannon 500 can spray out the received liquid to perform fire-fighting operations.
[0042] Optionally, in this embodiment, the fitting parts 210 are flange plates provided at both ends of the conduction pipe 200. After the conduction pipe 200 is assembled in the receiving space 110, the flange plates are attached to the inner wall of the fire tank 100, so as to facilitate the transition pieces 300 and the flange plates to jointly clamp the tank wall of the fire tank 100, and thus ensure the stable assembly of the flange plates and the transition pieces 300. In addition, the transition pieces 300 can also adopt a flange structure, such as a flange plate. In this embodiment, by arranging the transition pieces 300 outside the fire tank 100, after the assembly between the transition pieces 300 and the fitting parts 210 is realized first, and then the fire cannon 500 is arranged on the transition pieces 300, the assembly difficulty of the fire cannon 500 can be reduced, and the maintenance difficulty of the fire cannon 500 can be reduced.
[0043] As described above, in the fire monitor pipeline structure 10, the conduction pipe 200 is arranged in a manner independent of the fire monitor 500. In the case where the conduction pipe 200 needs to be maintained, the fire monitor 500 can be removed from the transition piece 300, and then the conduction pipe 200 can be independently removed from the fire tank 100, so as to achieve the maintenance or replacement of the conduction pipe 200, reducing the maintenance difficulty of the conduction pipe 200, and thus reducing the maintenance cost. On the other hand, since the conduction pipe 200 is arranged inside the fire tank 100, the overall occupied volume of the fire monitor pipeline structure 10 can be reduced, preventing complicated problems caused by pipelines. In addition, precisely because the conduction pipe 200 is independently arranged inside the fire tank 100, a steel pipe can be used to manufacture the conduction pipe 200, so that the conduction pipe 200 can meet the pressure requirements of the pipeline and can thus pass high-pressure liquid.
[0044] Optionally, please refer to Figure 2 and Figure 3 , in this embodiment, a blind hole installation hole 211 is provided on the fitting 210, and the connecting piece 400 is fitted with the blind hole installation hole 211. That is to say, the blind hole installation hole 211 does not penetrate through the fitting 210, and the blind hole installation hole 211 only has an opening on the side of the fitting 210 that fits against the inner wall of the fire tank 100. Therefore, by providing the blind hole installation hole 211 on the fitting 210, when the fitting 210 is attached to the inner wall of the fire tank 100, the blind hole installation hole 211 can be closed, thus avoiding the leakage of the liquid inside the fire tank 100 and improving the sealing performance of the fire tank 100.
[0045] In this embodiment, the blind hole installation hole 211 is a threaded hole.
[0046] Correspondingly, in order to facilitate the cooperation between the connecting piece 400 and the blind hole installation hole 211, the connecting piece 400 is a bolt. It should be noted that a hole is also provided on the transition piece 300, and the hole on the transition piece 300 penetrates through the transition piece 300 to facilitate the connecting piece 400 to pass through the transition piece 300. At the same time, a hole for avoiding the connecting piece 400 is also provided on the fire tank 100 to facilitate the connecting piece 400 to pass through the fire tank 100 and the fitting 210 for connection.
[0047] In this embodiment, a first sealing gasket 212 is provided between the fitting 210 and the fire tank 100. By providing the first sealing gasket 212, the sealing effect between the fitting 210 and the fire tank 100 can be further improved, thus preventing the leakage of the liquid inside the fire tank 100.
[0048] Optionally, the first sealing gasket 212 can adopt a sealing structure such as a rubber gasket or a silicone gasket. It only needs to achieve the sealing of the gap between the fitting 210 and the fire tank 100.
[0049] In addition, in this embodiment, a second gasket 320 is provided between the transition piece 300 and the fire tank 100. Setting the second gasket 320 between the transition piece 300 and the fire tank 100 can further improve the sealing performance of the fire tank 100, thereby preventing the liquid inside the fire tank 100 from leaking out.
[0050] Optionally, the second gasket 320 can adopt a sealing structure such as a rubber gasket or a silica gel gasket. It only needs to achieve the sealing of the gap between the transition piece 300 and the fire tank 100.
[0051] In this embodiment, the conduction pipe 200 and the fitting 210 are integrally formed. The process step of fixing the fitting 210 to the conduction pipe 200 can be omitted, reducing the manufacturing difficulty of the conduction pipe 200 and the manufacturing cost.
[0052] Optionally, a stepped hole 310 is further opened on the side of the transition piece 300 away from the fire tank 100. The connecting piece 400 passes through the stepped hole 310 and is connected to the fitting 210, and the connecting piece 400 is accommodated inside the stepped hole 310. In other words, the stepped hole 310 has a coaxial large hole and a small hole. After the connecting piece 400 passes through the large hole and the small hole in sequence, and then passes through the peripheral wall of the fire tank 100, it is connected to the fitting 210. Among them, the large hole can accommodate the head part of the connecting piece 400, so that the connecting piece 400 does not protrude from the outer surface of the transition piece 300, avoiding the connecting piece 400 from affecting the assembly of the fire cannon 500. That is, after the transition piece 300 and the fitting 210 are assembled, the connecting piece 400 is accommodated inside the stepped hole 310, preventing the connecting piece 400 from occupying a part of the outer surface area of the transition piece 300 and facilitating the connection between the fire cannon 500 and the transition piece 300.
[0053] In this embodiment, the conduction pipe 200 includes a first conduction section 201, a second conduction section 202, and a third conduction section 203. The first conduction section 201 is provided at one end close to the fire cannon 500, and the second conduction section 202 is provided between the first conduction section 201 and the third conduction section 203; an arc transition section 204 is provided between the first conduction section 201 and the second conduction section 202, and another arc transition section 204 is provided between the second conduction section 202 and the third conduction section 203, and an obtuse angle is formed between the first conduction section 201 and the second conduction section 202. Setting the arc transition section 204 between the first conduction section 201 and the second conduction section 202, and setting the arc transition section 204 between the second conduction section 202 and the first conduction section 201 can reduce the impact force of the high-pressure liquid on the peripheral wall of the conduction pipe 200, thereby reducing the probability of damage to the conduction pipe 200; further setting an obtuse angle between the first conduction section 201 and the second conduction section 202 can further reduce the impact force of the high-pressure liquid on the inner wall of the conduction pipe 200 and reduce the probability of damage to the conduction pipe 200.
[0054] It should be noted that the first conduction section 201, the second conduction section 202, the third conduction section 203, and the arc transition section 204 are formed by an integral molding method. It should be understood that in other embodiments of the present application, the conduction pipe 200 can also be arranged in other ways. For example, an obtuse angle is formed between the second conduction section 202 and the third conduction section 203.
[0055] Based on the provided fire cannon pipeline structure 10 above, in this embodiment, a fire truck (not shown in the figure) is also provided. The fire truck adopts the above-mentioned fire cannon pipeline structure 10. Therefore, the fire truck can also improve the problem of high maintenance difficulty and high maintenance cost of the pipeline connected to the fire cannon 500 in the prior art.
[0056] In summary, in the fire cannon pipeline structure 10 and the fire truck provided in this embodiment, the conduction pipe 200 is arranged independently of the fire cannon 500. When the conduction pipe 200 needs to be maintained, the fire cannon 500 can be removed from the transition part 300, and then the conduction pipe 200 can be independently removed from the fire tank 100, so as to realize the maintenance or replacement of the conduction pipe 200, reduce the maintenance difficulty of the conduction pipe 200, and further reduce the maintenance cost. On the other hand, since the conduction pipe 200 is arranged inside the fire tank 100, the overall occupied volume of the fire cannon pipeline structure 10 can be reduced, and the complicated problems caused by the pipeline can be prevented. In addition, precisely because the conduction pipe 200 is independently arranged inside the fire tank 100, a steel pipe can be used to manufacture the conduction pipe 200, so that the conduction pipe 200 can meet the pressure requirements of the pipeline and can pass high-pressure liquid. In addition, a blind hole installation hole 211 is arranged on the fitting 210. When the fitting 210 is attached to the inner wall of the fire tank 100, the blind hole installation hole 211 can be closed, so as to avoid the leakage of the liquid inside the fire tank 100 and improve the sealing performance of the fire tank 100. At the same time, through the arrangement of the first sealing gasket 212 and the second sealing gasket 320, the sealing performance of the fire tank 100 can be further improved, and the leakage of the liquid inside the fire tank 100 can be prevented.
[0057] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
