Description

Technical Field

[0001] This utility model relates to the technical field of water mist fire extinguishing devices, specifically to a high-pressure fine water mist fire extinguishing device for pipe gallery fire protection. Background Technology

[0002] Water mist fire suppression systems are highly efficient fire extinguishing systems based on high-pressure or special nozzle technology. They refine water flow into tiny water mist particles with a diameter of 100-1000 micrometers, utilizing their high specific surface area and strong permeability to achieve rapid cooling, suffocation, and suppression of reignition. Their advantages include water consumption of only 10%-20% of traditional water sprinklers, while avoiding water damage. They are suitable for electrical fires, oil fires, and confined spaces (such as computer rooms, archives, and substations). The system can be linked with smoke / temperature sensors for second-level response and is compatible with foam agent mixtures to enhance extinguishing efficiency against flammable liquids, combining environmental friendliness, economy, and safety.

[0003] Chinese patent CN219481400U discloses a high-pressure fine water mist fire extinguishing closed-loop nozzle, relating to the field of closed-loop nozzle technology. It includes a copper connecting pipe with a rust-proof fixing base below it. Inside the rust-proof fixing base is a fixing block. Below the fixing block are two sets of stainless steel water pipes symmetrically distributed below the rust-proof fixing base. A nozzle body is located at the bottom of each stainless steel water pipe, and spray holes are formed on the outer wall of the nozzle body. A temperature sensing element is fixed to the bottom of the fixing block. This high-pressure fine water mist fire extinguishing closed-loop nozzle, by having spray holes on the outer wall of the nozzle body, allows high-pressure fine water to be sprayed out from the spray holes, ensuring that the water is sprayed in the form of a fine water mist in all directions for fire extinguishing. This achieves the function of omnidirectional spraying, solving the problem of limited coverage and low fire extinguishing efficiency caused by single-port spraying in existing technologies, thereby improving fire extinguishing efficiency.

[0004] The high-pressure fine water mist fire extinguishing closed nozzle in the aforementioned patent document cannot rotate, which easily leads to uneven spraying or even dead zones when spraying water mist. Therefore, a high-pressure fine water mist fire extinguishing device for pipe gallery fire protection is proposed. Utility Model Content

[0005] To address the aforementioned issues, a high-pressure fine water mist fire extinguishing device for pipe gallery fire protection is provided. The device utilizes a rotating propeller, which simultaneously rotates a connecting pipe via a fixed rod. This rotation of the connecting pipe drives the mounting base at its base to rotate synchronously. This allows the mounting base to rotate and spray water mist, ensuring even coverage of the target area. This solves the problem of blind spots in water mist fire extinguishing devices.

[0006] To address the existing technical problems, this application provides a high-pressure fine water mist fire extinguishing device for pipe gallery fire protection, including a water pipe, a rotating mechanism disposed inside the water pipe, and a mounting base disposed at the bottom of the rotating mechanism. The rotating mechanism includes a connecting pipe rotatably installed inside the water pipe, a fixing rod longitudinally fixed at the center of the top end of the connecting pipe, and a propeller fixed at the top end of the propeller.

[0007] The bottom end of the water pipe is provided with a first mounting post;

[0008] The bottom end of the water pipe is equipped with a first nut to prevent the connecting pipe from falling off, and the first nut is threadedly connected to the first mounting post.

[0009] As one technical solution of this application, the connecting pipe is provided with a boss on the outside, a second rotatable sealing bearing assembly is provided on the top of the boss, and a first rotatable sealing bearing assembly is provided on the bottom of the boss.

[0010] Both the first and second sealed bearing assemblies are sleeved on the outside of the connecting pipe.

[0011] As one technical solution of this application, a limiting groove is formed on the side of the connecting pipe near the second sealing bearing assembly, and a limiting snap ring is installed inside the limiting groove to prevent the second sealing bearing assembly from sliding along the central axis of the connecting pipe.

[0012] As one technical solution of this application, a second mounting post is provided at the bottom end of the connecting pipe;

[0013] The top of the mounting base is provided with a second nut that can be threadedly connected to the second mounting post.

[0014] As one technical solution of this application, a second mounting groove is provided at the bottom of the mounting base;

[0015] The bottom of the mounting base is provided with a second nozzle, and the top of the second nozzle is installed inside the second mounting groove.

[0016] As one technical solution of this application, a plurality of first mounting grooves are equidistantly provided on the side wall of the mounting base around its central axis, and the first mounting grooves have downwardly inclined first nozzles.

[0017] As one technical solution of this application, the water pipe is provided with a limiting platform inside to limit the upward movement of the second sealing bearing assembly;

[0018] The first nut has a limiting ring inside, and the top of the limiting ring contacts the bottom of the first sealed bearing assembly.

[0019] The advantages of this utility model compared to the prior art are:

[0020] This application utilizes the rotation of a propeller, which simultaneously drives the connecting pipe to rotate via a fixed rod. This rotation of the connecting pipe, in turn, causes the mounting base at its bottom to rotate synchronously. This allows the mounting base to rotate and spray water mist, ensuring even coverage of the target area. This solves the problem of blind spots in water mist fire extinguishing devices.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0032] See Figures 1-9 As shown, a high-pressure fine water mist fire extinguishing device for pipe gallery fire protection includes a water pipe 1, a rotating mechanism 2 disposed inside the water pipe 1, and a mounting base 3 disposed at the bottom of the rotating mechanism 2. The rotating mechanism 2 includes a connecting pipe 20 rotatably installed inside the water pipe 1, a fixing rod 21 longitudinally fixed at the center of the top end of the connecting pipe 20, and a propeller 211 fixed at the top end of the propeller 211.

[0033] A first mounting post 12 is provided at the bottom end of water pipe 1;

[0034] The bottom end of the water pipe 1 is equipped with a first nut 13 to prevent the connecting pipe 20 from falling off. The first nut 13 is threadedly connected to the first mounting post 12.

[0035] When water flows downwards from inside water pipe 1 into connecting pipe 20, the propeller 211 fixed at the top of the fixing rod 21 rotates under the influence of the water flow. This rotation of the propeller 211, via the fixing rod 21, causes the connecting pipe 20 to rotate. Simultaneously, the rotation of the connecting pipe 20 causes the mounting base 3 at its bottom to rotate, enabling the mounting base 3 to rotate and spray water mist, ensuring even coverage of the target area and preventing blind spots in the water mist fire extinguishing system.

[0036] See Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, a boss 23 is provided on the outside of the connecting pipe 20, a rotatable second sealing bearing assembly 26 is provided on the top of the boss 23, and a rotatable first sealing bearing assembly 25 is provided on the bottom of the boss 23.

[0037] Both the first sealed bearing assembly 25 and the second sealed bearing assembly 26 are sleeved on the outside of the connecting pipe 20.

[0038] To ensure the effective rotation of the connecting pipe 20, the first sealing bearing assembly 25 and the second sealing bearing assembly 26 are fixed to the outside of the connecting pipe 20. Then, the connecting pipe 20 is installed inside the water pipe 1 through the first sealing bearing assembly 25 and the second sealing bearing assembly 26, thereby enabling the connecting pipe 20 to rotate effectively.

[0039] See Figure 3 , Figure 4 , Figure 8 and Figure 9As shown, a limiting groove 22 is provided on the side of the connecting pipe 20 near the second sealed bearing assembly 26. A limiting snap ring 27 is installed inside the limiting groove 22 to prevent the second sealed bearing assembly 26 from sliding along the central axis of the connecting pipe 20.

[0040] To prevent the second sealed bearing assembly 26 from detaching from the connecting pipe 20, a limiting groove 22 is formed on the outer wall of the connecting pipe 20, and a limiting snap ring 27 is installed inside the limiting snap ring 27. This limits the position of the second sealed bearing assembly 26, effectively preventing the second sealed bearing assembly 26 from moving along the central axis of the connecting pipe 20 and ensuring the stability of the second sealed bearing assembly 26.

[0041] See Figure 1 , Figure 3 Figure 5 and Figure 6 As shown, a second mounting post 24 is provided at the bottom end of the connecting pipe 20;

[0042] The top of the mounting base 3 is provided with a second nut 31 that can be threadedly connected to the second mounting post 24.

[0043] By setting a second nut 31 at the top of the mounting base 3 and then fitting the second nut 31 onto the second mounting post 24 at the bottom of the connecting pipe 20, the second nut 31 can fix the first mounting groove 32 to the bottom of the connecting pipe 20, preventing the mounting base 3 from falling off the bottom of the connecting pipe 20. This ensures the stability between the mounting base 3 and the connecting pipe 20.

[0044] See Figure 5 and Figure 6 As shown, a second mounting groove 34 is provided at the bottom of the mounting base 3;

[0045] The bottom of the mounting base 3 is provided with a second nozzle 35, and the top of the second nozzle 35 is installed inside the second mounting groove 34.

[0046] A second mounting groove 34 is opened at the center of the bottom of the mounting base 3. The top of the second nozzle 35 is then installed inside the second mounting groove 34, so that the second nozzle 35 communicates with the interior of the mounting base 3, so that the interior of the mounting base 3 can be sprayed downward through the second nozzle 35.

[0047] See Figure 5 and Figure 6 As shown, a number of first mounting slots 32 are equidistantly provided on the side wall of the mounting base 3 around its central axis, and the first mounting slots 32 have downwardly inclined first nozzles 33.

[0048] By creating several first mounting slots 32 at equal intervals on the side wall of the mounting base 3, and then installing the input end of the first nozzle 33 inside the first mounting slot 32, the first nozzle 33 is connected to the interior of the mounting base 3. This allows water inside the mounting base 3 to be sprayed outwards through the first nozzle 33, thus increasing the spraying range of the mounting base 3.

[0049] See Figure 9 As shown, the inside of the water pipe 1 is provided with a limiting platform 11 for blocking the upward movement of the second sealing bearing assembly 26;

[0050] The first nut 13 has a limiting ring 131 inside, and the top of the limiting ring 131 contacts the bottom of the first sealed bearing assembly 25.

[0051] To ensure the stability of the connecting pipe 20, a limiting platform 11 is provided inside the water pipe 1. When the connecting pipe 20 is installed inside the water pipe 1, the top of the second sealing bearing assembly 26 installed outside the connecting pipe 20 contacts the limiting platform 11, allowing the limiting platform 11 and the second sealing bearing assembly 26 to cooperate in limiting the connecting pipe 20. This effectively prevents the connecting pipe 20 from moving upward along the central axis of the water pipe 1. A limiting ring 131 is provided on the lower end face of the first nut 13, allowing the top of the limiting ring 131 inside the first nut 13 to contact the lower end face of the first sealing bearing assembly 25 installed on the connecting pipe 20 when the first nut 13 is installed on the first mounting post 12. This allows the limiting ring 131 and the first sealing bearing assembly 25 to cooperate in limiting the connecting pipe 20, effectively preventing the connecting pipe 20 from falling out of the water pipe 1. This, in turn, ensures the stability of the connecting pipe 20.

[0052] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
