Description

Technical Field

[0001] The invention relates to the field of fire-fighting water cannons, and in particular to an impact-resistant water cannon rotating nozzle and an impact-resistant fire-fighting water cannon. Background Art

[0002] Fire water cannon is suitable for extinguishing fires at a long distance and is widely used in petrochemical enterprises, storage tank areas, hangars, warehouses, port terminals and garages. The working principle of fire water cannon is that when a fire occurs, the front-end detector of the fire water cannon automatically collects infrared images of the fire scene, and automatically detects and locates the fire location through the central controller. After the cannon head of the water cannon adjusts its position, the solenoid valve is activated to open the pipeline to spray directly on the fire location until the fire source is extinguished. The fire water cannon with a symmetrical structure of double U-shaped tubes has the characteristics of good torsion resistance, high spraying accuracy, and is increasingly widely used; but the problem in use is that at the moment when the solenoid valve opens the pipeline to start the water cannon, the two high-pressure water flows in the U-shaped tubes on both sides are synchronously merged into the three-way pipe where the cannon head is installed, which will instantly generate a huge impact force in the three-way pipe, and the flange between the U-shaped tube and the three-way pipe cannot withstand the impact force and explodes, resulting in the scrapping of the water cannon, and the detached U-shaped tube and the cannon head falling from a high altitude will cause huge safety hazards. Summary of the invention

[0016] Embodiment 1, see attached Figure 1-3 8-10, an impact-resistant fire-fighting water monitor, comprising two U-shaped tubes 12 symmetrically installed at both ends of the upper part of a three-way base 11 and an impact-resistant water monitor rotating nozzle, wherein the rotating joints 15 at both ends of the rotating nozzle are respectively connected to the ports of the two U-shaped tubes 12, and a worm gear mechanism is provided on the water monitor to drive the nozzle to rotate.

[0017] The impact-resistant water cannon rotating nozzle includes a three-way pipe seat 13 with a gun head 14 installed, and a rotating joint 15 is installed at both ends of the three-way pipe seat 13. The rotating joint and the U-shaped tube 12 are connected by a flange. At least three high-strength screws are evenly distributed on the flange to ensure that the rotating joint 15 and the U-shaped tube 12 have sufficient connection strength. A transverse pulling reinforcement structure is provided in the transverse tube body of the three-way pipe seat 13, and the transverse pulling reinforcement structure includes a screw rod armor 32 and a bracket armor 31 arranged on the inner side of the rotating joint 15. The screw rod armor 32 is coaxially inserted into the transverse tube body, and a partition 51 is provided in the middle of the transverse tube body. The partition is used to avoid axial collision and confluence of two water flows, reduce kinetic energy consumption, and help to increase the range of the water cannon. A through hole 52 is provided on the partition 51, and the screw rod armor 32 passes through the through hole 52. The two ends of the screw rod armor 32 are respectively threadedly connected to the middle of the two bracket armors 31.

[0018] A through hole is provided in the middle of the bracket A 31, and the through hole is set as a threaded hole 44 to connect with the screw A 32, or the end of the screw A 32 passes through the through hole and a nut is installed on its extended section for connection. The nut is a cap nut 33. The round head structure of the cap nut itself can provide guidance for the water flow and reduce the resistance it produces to the water flow. At the same time, it can close the end of the screw A 32 to prevent the impact of water flow from affecting the strength of the threaded connection.

[0019] This embodiment establishes a pulling connection structure between the rotary joints 15 at both ends of the rotating sprinkler head through the screw rod A 32. The rotary joint 15 is connected to the U-shaped tube 12 through a flange. When the water cannon is started, the instantaneous water flow will generate a huge impact force in the rotating sprinkler head. At this time, the rotating connection structure of the rotating sprinkler head itself combined with the axial pulling force of the internal screw rod A 32 can fully resist the huge impact force generated by the two water flows, ensure the safety and stability of the water cannon's own structure, and avoid the phenomenon that the U-shaped tube 12 and the rotary joint 15 are separated and exploded due to the instantaneous impact force when the water cannon is started.

[0020] Embodiment 2, see attached Figure 1-7 A shock-resistant fire-fighting water monitor comprises two U-shaped tubes 12 symmetrically installed at both ends of the upper part of a three-way base 11 and a shock-resistant water monitor rotating nozzle. The rotating joints 15 at both ends of the rotating nozzle are respectively connected to the ports of the two U-shaped tubes 12. A worm gear mechanism is provided on the water monitor to drive the nozzle to rotate.

[0021] The impact-resistant water cannon rotating nozzle includes a three-way pipe seat 13 on which a gun head 14 is installed. A rotating joint 15 is installed at both ends of the three-way pipe seat. The rotating joint and the U-shaped tube 12 are connected by a flange. At least three high-strength screws are evenly distributed on the flange to ensure that the rotating joint 15 and the U-shaped tube 12 have sufficient connection stability. A transverse pulling reinforcement structure is provided in the transverse tube body of the three-way pipe seat 13. The transverse pulling reinforcement structure includes a screw rod B 42 and a bracket B 41 arranged on the inner side of the U-shaped tube 12 port on both sides of the water cannon. The screw rod B 42 is coaxially inserted into the transverse tube body. A partition 51 is provided in the middle of the transverse tube body. The partition is used to avoid axial collision and confluence of two water flows, reduce kinetic energy consumption, and help to increase the range of the water cannon. A through hole 52 is provided on the partition 51, and the screw rod B 42 passes through the through hole 52. The two ends of the screw rod B are respectively threadedly connected to the middle of the two brackets B 41.

[0022] A through hole is provided in the middle of bracket B 41, and the through holes on both sides are set as threaded holes 44 connected to screw rod B 42. The through hole in the middle of bracket B 41 on one side is set as a threaded blind hole 43, or a step is set at the junction of the threaded section of screw rod B 42 and the optical axis section.

[0023] This embodiment directly establishes a pulling connection structure between the ports of the two U-shaped tubes 12 through the screw rod B 42. The instantaneous water flow when the water cannon is started will generate a huge impact force in the rotating nozzle between the two U-shaped tubes 12. At this time, the rotating connection structure of the rotating nozzle itself combined with the axial pulling force of the internal screw rod B 42 can fully resist the huge impact force generated by the two water flows, ensure the safety and stability of the water cannon's own structure, and avoid the phenomenon that the U-shaped tube 12 and the rotating joint 15 are separated and the cannon exploded due to the instantaneous impact force when the water cannon is started.

[0024] When assembling the rotating nozzle of the water cannon of this embodiment, first connect the U-shaped tube 12 on one side to the three-way base 11, then install the two rotating joints 15 on the two ends of the three-way pipe seat 13, and connect the rotating joint 15 at one end to the U-shaped tube 12 on one side through a flange, then coaxially insert the screw rod 42 from the rotating joint 15 at the other end into the inside of the transverse tube of the three-way pipe seat 13, screw the screw rod 42 to thread its end into the threaded blind hole 43 in the middle of the bracket 41, and after screwing it into place, correspond the bracket 41 on the U-shaped tube 12 on the other side to the other end of the screw rod 42, and slowly screw the bracket 41 onto the screw rod 42 by rotating the U-shaped tube 12, and after screwing it into place, connect the two ends of the U-shaped tube 12 to the three-way base 11 and the corresponding rotating structure flange respectively to complete the assembly.
