Description

Technical Field

[0001] This invention relates to the field of fire rescue technology, and in particular to a fire hose with spray cooling and puncture functions. Background Technology

[0002] Fire hoses are one of the most common firefighting tools. During firefighting, they are connected to fire hoses or fire trucks to spray a dense and powerful stream of water. Commonly used fire hoses include straight stream hoses and spray hoses. Regardless of the type, the hose and hose are locked together using a hose clip. When a vehicle chassis catches fire, especially in new energy vehicles, a large amount of water is needed for extinguishing and cooling. However, conventional fire hoses, due to their limited angle, cannot accurately target the fire or fully cover and cool the vehicle chassis. Furthermore, existing chassis cooling devices are too bulky, inconvenient to operate, and waste valuable equipment storage space on fire trucks. Fire hoses with spray cooling and piercing capabilities, particularly those with spray cooling nozzles, are ideal for special fires such as smoldering solid fires like cotton stacks, haystacks, and grain stacks, as well as fires in enclosed spaces where conventional fire hoses are difficult to use. In these cases, it is necessary to first break through or pierce the fire near the source before spraying the fire hose.

[0003] For example, a fire hose disclosed in Chinese patent CN206950517U can quickly penetrate into the interior of stacked solid materials and spray extinguishing agent, effectively reducing the internal temperature of the burning solid materials, reducing the difficulty of extinguishing the fire, and improving the extinguishing efficiency. However, the following problems still exist in its use:

[0004] Because the existing piercing water guns on the equipment market have limited functions and cannot be used for extinguishing and cooling vehicle chassis fires, while the innovative vehicle chassis cooling devices in various places are all relatively large in size. Although they can meet the needs of fire fighting and rescue sites, their large size and weight make them inconvenient for fire trucks to carry and transport at the rescue site, thus affecting rescue efficiency.

[0005] Furthermore, traditional fire nozzle clips are fixed using a threaded connection method. This connection method cannot guarantee the reliability of the connection after the threads wear down. Prolonged high-pressure water spray from the fire nozzle may cause the two to detach, which could injure firefighters. Summary of the Invention

[0006] The purpose of this invention is to provide a fire hose with spray cooling and puncture functions, which solves the technical problems mentioned in the background art.

A rubber pad is fixedly connected to one side of the sliding plate. The outer wall of one side of the rubber pad is in contact with the inner wall of one side of the annular groove.

[0010] Another objective of this invention is to provide two fire extinguishing modes, enabling it to meet the needs of fire suppression for various vehicle chassis and cooling for fires in new energy vehicle batteries. The operation is simple, reducing the operational burden on personnel while effectively improving operational efficiency. Therefore, based on the above technical solutions, this invention also proposes the following technical solutions:

[0018] Compared with related technologies, the fire hose with spray cooling and puncture functions provided by the present invention has the following beneficial effects:

[0019] 1. This invention provides a fire hose nozzle with spray cooling and piercing functions. When the threaded connector is screwed into the threaded sleeve, the connector gradually approaches the connecting ring, and the sliding column moves into the convex annular groove. When the connector rotates, the sliding column can easily slide along the inner wall of the convex annular groove until it slides into the inner wall of the concave annular groove. At this time, the sliding cylinder can easily slide along the inner wall of the cross groove, and the sliding plate slides along the inner wall of the sliding groove. The limiting collar moves synchronously, that is, it moves synchronously with the sliding column in the limiting collar. The sliding plate and the rubber pad move until the rubber pad is in contact with the inner wall of the annular groove, which plays a certain limiting role. That is, the connector and the connecting ring are fixed, avoiding the problem of unstable connection when the threaded connector and the threaded sleeve are loose, ensuring the reliability of the connection, avoiding the risk of separation between the two due to long-term high-pressure water spray from the fire hose nozzle, avoiding injury to firefighters, and improving safety performance.

[0020] 2. This invention provides a fire hose with spray cooling and puncture functions. The puncture head assembly is connected and fixed to the water supply pipe via a threaded sleeve and connecting assembly, allowing for quick assembly into a puncture hose by replacing parts. Similarly, the cooling nozzle assembly is connected and fixed to the water supply pipe via a threaded sleeve and connecting assembly, allowing for quick assembly into a cooling hose by replacing parts. The puncture head assembly is suitable for smoldering solid materials such as cotton stacks, haystacks, and grain stacks, as well as enclosed spaces, significantly saving carrying space. It is small in size and lightweight, facilitating on-site operation. It features two fire extinguishing modes, meeting the needs of various vehicle chassis fire suppression and new energy vehicle battery fire cooling. Its simple operation reduces operator workload and effectively improves operational efficiency.

[0021] 3. This invention provides a fire hose with spray cooling and piercing functions. When the cooling water pipe is placed on the ground, one side of the arc-shaped pad is placed against the ground to prevent the cooling water pipe from directly contacting the ground. The elasticity of the rubber block and the buffer spring itself can buffer some of the vibration. When the arc-shaped pad is placed on the ground or in the vehicle, it is more stable and less prone to rolling than the round pipe is placed directly, resulting in better performance. The limit ring makes it easy for the user to hold with both hands and facilitates the connection between the water supply pipe and the threaded sleeve. The mirrored design is for the stable placement of the water supply pipe. Attached Figure Description

[0039] The anti-detachment component 3 includes a connector 301, one side of which is fixedly connected to one side of the threaded connector 2. The connector 301 has a hollow cylindrical structure. The threaded connector 2 is fixedly connected to the connector 301 for easy fixation. The hollow cylindrical structure facilitates water flow. An annular baffle 302 is fixedly connected to one side of the outer wall of the connector 301. An annular groove 303 is provided on one side of the annular baffle 302. A convex annular groove 304 is provided on one side of the outer wall of the connector 301. A concave annular groove 305 flows through one side of the convex annular groove 304.

[0040] The connecting assembly 9 includes a connecting ring 901. A cross groove 902 is formed on one side of the connecting ring 901. A sliding block 903 is slidably connected to the inner wall of one side of the cross groove 902. A sliding cylinder 904 is connected through and fixedly connected to the interior of the sliding block 903. The outer wall of the sliding cylinder 904 is slidably connected to the inner wall of the cross groove 902, allowing the sliding cylinder 904 to slide along the inner wall of the cross groove 902. A telescopic spring 905 is fixedly connected to the inner wall of the sliding cylinder 904. A sliding post 906 is fixedly connected to the bottom of the telescopic spring 905. The size of the sliding post 906 is adapted to the sizes of the convex annular groove 304 and the concave annular groove 305, respectively. The outer wall of the sliding post 906 is slidably connected to the inner walls of the convex annular groove 304 and the concave annular groove 305, allowing the sliding post 906 to slide along the inner walls of the convex annular groove 304 and the concave annular groove 305. A limiting collar 907 is fitted around the outer wall of the sliding column 906. A sliding groove 910 is provided on one side of the connecting ring 901 and below the cross groove 902. A sliding plate 908 is slidably connected to the inner wall of the sliding groove 910. The sliding plate 908 is fixedly connected to the limiting collar 907. When the sliding plate 908 slides along the inner wall of the sliding groove 910, the limiting collar 907 moves synchronously, thereby driving the sliding column 906 inside the limiting collar 907 to move. A rubber pad 909 is fixedly connected to one side of the sliding plate 908. The outer wall of one side of the rubber pad 909 is in contact with the inner wall of one side of the annular groove 303. When the rubber pad 909 is in contact with the inner wall of the annular groove 303, it plays a limiting role, that is, the connector 301 and the connecting ring 901 are fixed together, avoiding the problem of unstable connection when the threaded joint 2 and the threaded sleeve 7 are loose.

[0041] In this embodiment, when the threaded connector 2 is screwed into the threaded sleeve 7, the connector 301 gradually approaches the connecting ring 901. At this time, one side of the outer wall of the sliding column 906 contacts one side of the outer wall of the connector 301, and the telescopic spring 905 is in a compressed state. As the threaded connection between the threaded connector 2 and the threaded sleeve 7 is established, the connector 301 rotates accordingly, that is, the convex annular groove 304 and the concave annular groove 305 rotate accordingly until they correspond to the position of the sliding column 906. At this point, the sliding column 906 moves into the convex annular groove 304, and when the connector 301 rotates, the sliding column 906 can easily slide along the inner wall of the convex annular groove 304 until it slides into the interior of the concave annular groove 305. At this time, the sliding cylinder 904 can slide along the inner wall of the cross groove 902, the sliding plate 908 slides along the inner wall of the sliding groove 910, and the limiting collar 907 moves synchronously, that is, moves synchronously with the sliding column 906 inside the limiting collar 907. The sliding plate 908 and the rubber pad 909 move until the rubber pad 909 and the inner wall of the annular groove 303 fit together, which plays a certain limiting role. That is, the connector 301 and the connecting ring 901 are fixed, avoiding the problem of unstable connection when the threaded joint 2 and the threaded sleeve 7 are loose, ensuring the reliability of the connection, avoiding the risk that the two may separate due to the long-term high-pressure water spray of the fire nozzle, avoiding injury to firefighters, and improving safety performance.

[0042] The piercing head assembly 6 is connected and fixed to the water supply hard pipe 1 via the threaded sleeve 7 and the connecting assembly 9, allowing for quick assembly into a piercing water gun by replacing parts. The cooling nozzle assembly 8 is also connected and fixed to the water supply hard pipe 1 via the threaded sleeve 7 and the connecting assembly 9, allowing for quick assembly into a cooling water gun by replacing parts. The piercing head assembly 6 is used for smoldering solids such as cotton stacks, haystacks, and grain stacks, as well as in enclosed spaces. It greatly saves carrying space and has the advantages of small size and light weight. It is also conducive to on-site operation and has two fire extinguishing modes, which can meet the functions of fire fighting on the chassis of various vehicles and cooling of battery fires in new energy vehicles. It is easy to operate, reducing the operating pressure on operators while effectively improving operational efficiency.

[0043] Example 2:

[0045] A cooling nozzle assembly 8 is fixedly connected to one side of the threaded sleeve 7 via a connecting component 9. The cooling nozzle assembly 8 includes a cooling water pipe 801. Three large nozzles 802 are fixedly connected to the outer wall of one side of the cooling water pipe 801, with a spacing of 50cm between them. Six small nozzles 803 are fixedly connected to each large nozzle 802, evenly distributed at a 45-degree angle. The central nozzle 804 is located at the center of the six small nozzles 803. The orifice diameter of each small nozzle 803 and the central nozzle 804 is 2.8mm. The small nozzles 803 and the central nozzle 804 are used to spray mist-like water. A connecting ring 901 is fixedly connected to one side of the cooling water pipe 801 and the threaded sleeve 7. The cooling water pipe 801 has a first row of holes 805 and a second row of holes 806 evenly arranged on both side walls. The diameter of both rows of holes 805 and 806 is 2mm, and the spacing between them is 20cm. The purpose of the first row of holes 805 and 806 is to spray water directly onto the ground on both sides, increasing the cooling coverage area. The angle between the first row of holes 805 and the ground is 15-20 degrees, and the angle between the second row of holes 806 and the ground is 20-25 degrees. The height of both rows of holes 805 and 806 is above the horizontal line. Figure 5 The position indicated by the dotted line shows that both rows of holes allow the sprayed water to travel further, achieving the effect of one water gun covering the entire chassis area of ​​a vehicle. The two rows of small holes intersect each other axially, rather than being side by side, allowing them to complement each other in axial coverage, resulting in a better spraying effect.

[0046] In this embodiment, the connecting ring 901 is used to connect and fix the connecting pipe 601 and the threaded sleeve 7. The piercing head assembly 6 is connected and fixed to the water supply hard pipe 1 through the threaded sleeve 7 and the connecting assembly 9.

[0048] Example 3:

[0049] Please see Figures 9-13 As shown, based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: an arc-shaped groove 11 is provided on one outer wall of the cooling water pipe 801, a buffer spring 12 is fixedly connected to one inner wall of the arc-shaped groove 11, an arc-shaped pad 13 is fixedly connected to the side of the buffer spring 12 away from the inner wall of the arc-shaped groove 11, a rubber block 14 is fixedly connected to one side of the arc-shaped groove 11, and one outer wall of the arc-shaped pad 13 is fixedly connected to one side of the rubber block 14. When the cooling water pipe 801 is placed on the ground, one side of the arc-shaped pad 13 is placed against the ground to avoid the cooling water pipe 801 directly contacting the ground, and the elasticity of the rubber block 14 and the buffer spring 12 can buffer off part of the vibration.

[0050] Two limiting rings 10 are hinged to one outer wall of the water supply pipe 1. These two limiting rings 10 are mirror images of each other about the axis of the water supply pipe 1. The two limiting rings 10 are designed for easy handholding, and the mirror image arrangement facilitates stable placement of the water supply pipe 1. A magnetic block 15 is fixedly connected to one outer wall of each limiting ring 10. The outer wall of the magnetic block 15 is magnetically attracted to the inner wall of the magnetic groove 16. After being attached to the magnetic groove 16, it is easy to magnetically fix it. A insertion groove 17 is provided on one side of the inner wall of the magnetic groove 16. A return spring 18 is fixedly connected to one side of the inner wall of the insertion groove 17. An arc-shaped locking block 19 is fixedly connected to one side of the return spring 18. An arc-shaped locking groove 20 is provided on one side of the outer wall of the magnetic block 15. One side of the outer wall of the arc-shaped locking block 19 and one side of the inner wall of the arc-shaped locking groove 20 are interlocked. The arc-shaped locking block 19 and the arc-shaped locking groove 20 are easy to interlock and fix.

[0051] In this embodiment, when the cooling water pipe 801 is placed on the ground, the arc-shaped pad 13 is placed with one side against the ground to prevent the cooling water pipe 801 from directly contacting the ground. The elasticity of the rubber block 14 and the buffer spring 12 can also buffer some of the vibration. When the arc-shaped pad 13 is placed on the ground or inside the vehicle, it is more stable and less prone to rolling than when the round pipe is placed directly, resulting in better performance.

[0052] The limiting ring 10 is designed to facilitate the user's two-hand grip and the connection between the water supply hard pipe 1 and the threaded sleeve 7. The mirrored design is designed to facilitate the stable placement of the water supply hard pipe 1. When the limiting ring 10 is rotated, the arc-shaped locking block 19 and the arc-shaped locking groove 20 gradually separate, and the magnetic suction block 15 and the magnetic suction groove 16 separate from each other. The limiting ring 10 can be rotated to any position, which facilitates the use of the limiting ring 10.

[0053] Working principle:

[0054] In use, firstly, as the threaded connector 2 is screwed into the threaded sleeve 7, the connector 301 gradually approaches the connecting ring 901. At this time, one side of the outer wall of the sliding column 906 contacts one side of the outer wall of the connector 301, and the telescopic spring 905 is in a compressed state. As the threaded connection between the threaded connector 2 and the threaded sleeve 7 is established, the connector 301 rotates accordingly, that is, the convex annular groove 304 and the concave annular groove 305 rotate accordingly until they correspond to the position of the sliding column 906. Then, the sliding column 906 moves into the convex annular groove 304, and when the connector 301 rotates, the sliding column 906 can easily slide along the inner wall of the convex annular groove 304 until it slides into the concave annular groove 305. At this time, the sliding cylinder 904 can slide along the inner wall of the cross groove 902, the sliding plate 908 slides along the inner wall of the sliding groove 910, and the limiting collar 907 moves synchronously, that is, moves synchronously with the sliding column 906 inside the limiting collar 907. The sliding plate 908 and the rubber pad 909 move until the rubber pad 909 and the inner wall of the annular groove 303 fit together, which plays a certain limiting role. That is, the connector 301 and the connecting ring 901 are fixed, avoiding the problem of unstable connection when the threaded joint 2 and the threaded sleeve 7 are loose, ensuring the reliability of the connection, avoiding the risk that the two may separate due to the long-term high-pressure water spray of the fire nozzle, avoiding injury to firefighters, and improving safety performance.

[0055] Secondly, the connecting ring 901 is used to connect and fix the connecting pipe 601 and the threaded sleeve 7. The piercing head assembly 6 is connected and fixed to the water supply hard pipe 1 through the threaded sleeve 7 and the connecting assembly 9. It is convenient to quickly assemble a piercing water gun by replacing parts. The piercing head assembly 6 is used for solid smoldering such as cotton stacks, hay stacks, and grain stacks, as well as enclosed spaces. It greatly saves carrying space and has the advantages of small size and light weight. It is also conducive to on-site operation, improves action efficiency, and improves action safety.

[0056] Furthermore, the connecting ring 901 is used to connect and fix the cooling water pipe 801 and the threaded sleeve 7. The cooling nozzle assembly 8 is connected and fixed to the water supply hard pipe 1 through the threaded sleeve 7 and the connecting assembly 9. It is convenient to quickly assemble into a cooling water gun by replacing parts. It has a small and portable size and weight, and has two fire extinguishing modes. It can meet the functions of fire fighting of various vehicle chassis and cooling of new energy vehicle battery fires. It is easy to operate, which can reduce the operating pressure of operators and effectively improve the efficiency of operation.

[0057] Finally, when the cooling water pipe 801 is placed on the ground, the arc-shaped pad 13 is placed with one side against the ground to prevent the cooling water pipe 801 from directly contacting the ground. The elasticity of the rubber block 14 and the buffer spring 12 can also buffer some of the vibration. When the arc-shaped pad 13 is placed on the ground or inside the vehicle, it is more stable and less prone to rolling than when the round pipe is placed directly, resulting in better performance. The small nozzle 803 and the center nozzle 804 are used to spray mist water. The first row of holes 805 and the second row of holes 806 can make the distance of the sprayed water flow longer. When used together, one water gun can cover the entire chassis area of ​​a vehicle.

[0058] The limiting ring 10 is designed to facilitate the user's two-hand grip and the connection between the water supply hard pipe 1 and the threaded sleeve 7. The mirrored design is designed to facilitate the stable placement of the water supply hard pipe 1. When the limiting ring 10 is rotated, the arc-shaped locking block 19 and the arc-shaped locking groove 20 gradually separate, and the magnetic suction block 15 and the magnetic suction groove 16 separate from each other. The limiting ring 10 can be rotated to any position, which facilitates the use of the limiting ring 10.
