The rotating shaft is cylindrical and has through holes evenly arranged on its side. The rotating shaft is rotatably connected to the outer surface of a coaxial shaft and is slidably connected to the coaxial shaft in the axial direction. A rotating disk is located on the outer surface of a rotating shaft. The rotating disk is connected to a through hole on the outer surface of the rotating shaft. The rotating disk includes a disk body fixedly connected to the outer surface of the rotating shaft, and a jet channel is connected inside the disk body. A fixed joint is fixedly connected to the front of the rotating shaft. The fixed joint is located on the front of the coaxial shaft. A through hole is provided on the back of the fixed joint. There is a gap between the inner wall of the fixed joint and the outer surface of the coaxial shaft. A hole opener is fixedly connected to the front of a fixed joint, and the back of the hole opener communicates with the through hole of the fixed joint.

[0005] Preferably, a positioning block is fixedly connected to the front of the fixed horizontal plate, and protruding plates are fixedly connected to the left and right sides of the positioning block. The hole opener is located inside the positioning block, the front surface of the hole opener is serrated, and a through hole is opened on the outer surface of the hole opener.

[0006] Preferably, the rotating disk is composed of two symmetrical structures joined together, one end of the jet channel is connected to the rotating shaft, and the other end of the jet channel is connected to the external air.

[0007] Preferably, the coaxial cable has two rows of through holes, one row being close to the front of the coaxial cable and the other row being close to the back of the coaxial cable.

[0008] Preferably, the telescopic rod includes a rod body, one end of which is fixedly connected to a top hook, and the bottom of the top hook is fixedly connected to a stop bar.

[0011] Preferably, a connector is fixedly connected to the back of the fixing collar, and the connector is connected to an external fire hose.

[0012] This invention provides a fire-fighting puncture extinguishing device that integrates cutting and spraying functions. It has the following beneficial effects: 1. This fire extinguishing device, which integrates cutting and spraying functions, uses a telescopic rod and a fixing mechanism. By fixing the top hook and the container locking rod, and using the winch to wind up the flexible cable to lift the device, it allows operators to remotely extinguish fires from the ground. Ultimately, it achieves safe operation with personnel away from potentially dangerous areas and solves the problem of extinguishing fires in high-stacked containers.

[0013] 2. This integrated fire-fighting puncture extinguishing device combines cutting and spraying functions. By setting up a cutting nozzle assembly, it utilizes fire water pressure to drive a rotating disc at high speed. The rotating disc is hollowed out near the rotating shaft, increasing the water volume within the disc and thus increasing the water pressure entering the spray channel. Simultaneously, the corrugated cross-section variable diameter spray channel increases the pressure of the water jet from the spray channel, thereby increasing the rotation speed of the rotating disc. This, in turn, drives the hole opener to achieve high-speed rotating drilling and automatically switches the water flow path after drilling. It achieves a fully automated operation cycle from demolition to fire extinguishing using only fire water pressure, ultimately realizing efficient fire extinguishing inside containers under confined space conditions.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0018] Example Please see Figure 1-11This invention provides a technical solution: a fire extinguishing device integrating cutting and spraying functions, including a fixed horizontal plate 1 and a telescopic rod 8. A positioning block 11 is fixedly connected to the front of the fixed horizontal plate 1, and protruding plates are fixedly connected to the left and right sides of the positioning block 11. A connecting plate 2 is fixedly connected to the back of the fixed horizontal plate 1, and a fixing collar 3 is fixedly connected to the back of the connecting plate 2. A coaxial 31 is fixedly connected to the front of the fixing collar 3. The coaxial 31 is a cylinder, and through holes are evenly arranged on the outer surface of the coaxial 31. There are two rows of through holes in the coaxial 31, one row is close to the front of the coaxial 31, and the other row is close to the back of the coaxial 31. A clamping plate 4 is fixedly connected to the top of the fixed horizontal plate 1, and a spring lock 5 is fixedly connected to the bottom of the clamping plate 4. A fixing plate is fixedly connected to the front of the clamping plate 4. The fixing plate is made of the same material as the clamping plate 4. A hook-shaped plate is fixedly connected to the bottom of the clamping plate 4. The hook-shaped plate is used to fix the clamping plate 4 to the top of the fixed horizontal plate 1 together with the spring lock 5. The spring lock 5 is fixedly connected to the fixed horizontal plate 1. A cutting nozzle assembly 6 is provided on the front of the fixing collar 3. Cutting nozzle assembly 6 includes: Rotating shaft 61 is located on the front of fixed collar 3. Rotating shaft 61 is a cylinder. Through holes are evenly arranged on the side of rotating shaft 61. Rotating shaft 61 is rotatably connected to the outer surface of coaxial 31. Rotating shaft 61 is slidably connected to coaxial 31 in the axial direction. Rotary disk 62 is located on the outer surface of rotating shaft 61. Rotary disk 62 is connected to a through hole on the outer surface of rotating shaft 61. Rotary disk 62 includes a disk body 621 fixedly connected to the outer surface of rotating shaft 61. A jet channel 622 is connected inside the disk body 621. Fixed connector 63 is fixedly connected to the front of rotating shaft 61. Fixed connector 63 is located on the front of coaxial 31. A through hole is provided on the back of fixed connector 63. There is a gap between the inner wall of fixed connector 63 and the outer surface of coaxial 31. The front of the inner wall of fixed connector 63 is in contact with the front of coaxial 31. Hole opener 64 is fixedly connected to the front of fixed connector 63. The back of hole opener 64 is connected to the through hole of fixed connector 63. Hole opener 64 is located inside positioning block 11. The front surface of hole opener 64 is serrated. The outer surface of hole opener 64 is provided with through hole. Hole opener 64 can be disassembled and replaced. The back of the fixing collar 3 is fixedly connected to the connector 7, which is connected to the external fire hose. The connector 7 is a standard C-type DN50 port. The telescopic pole 8 includes a pole body 81, which can extend and retract to adjust its length. A top hook 82 is fixedly connected to one end of the pole body 81, and a stop bar is fixedly connected to the bottom of the top hook 82. A winch 83 is fixedly connected to the other end of the pole body 81, and a pulley 84 is fixedly connected to one end of the pole body 81. The winch 83 is rotatably connected to the pulley 84 via a flexible cable.

[0019] When in use, first connect the connector 7 to the fire hose, then place the clamping plate 4 on the back of the standard container locking bar, and let the fixing plate abut against the locking bar of the standard container door panel. At the same time, let the protruding plates on both sides of the positioning block 11 hook onto the back of the container locking bar, thereby completing the fixing of the device. At this time, the front of the hole opener 64 abuts against the container door panel. After fixing, water is supplied to the device through a fire hose. The water flows through the connector 7, the fixing collar 3, and the rotating disk 62 in sequence. A portion of the water enters the disk body 621. The rotating disk 62 is hollowed out near the rotating shaft 61 to increase the water volume in the rotating disk. The spray channel 622 undergoes multiple diameter changes to increase the pressure of the water jetting out of the spray channel. The water is discharged from the spray channel 622. The kinetic energy generated by the high-speed water jetting out of the spray channel 622 (counterclockwise) drives the rotating disk 62 to rotate in the opposite direction at high speed (clockwise). The rotating disk 62 drives the rotating shaft 61 to rotate, the rotating shaft 61 drives the fixing connector 63 to rotate, and the fixing connector 63 drives the opening device 64 to rotate. When the hole drill 64 rotates, it begins to drill a hole in the container door panel. At the same time, water pressure pushes the fixed joint 63 forward, which in turn drives the rotating shaft 61 to apply a pressure perpendicular to the door panel to the hole drill 64, thus advancing the hole drill 64. Before the hole in the door panel is drilled through, the water flow mainly drives the rotating disk 62 to rotate. After the hole in the door panel is drilled through, the rotating shaft 61 slides forward under the drive of the fixed joint 63, causing the front of the inner wall of the fixed joint 63 to move away from the front of the coaxial 31. The water flow flows along the hole, and then the water flow is sprayed from the rotating shaft 61 through the fixed joint 63 and the hole drill 64 into the container for fire extinguishing. When the standard container requiring firefighting is at a higher position, extend the rod 81 until the top hook 82 reaches the height of the container requiring firefighting. Then, let the stop bar of the top hook 82 pass through the back of the container locking rod, thereby fixing the top hook 82 and the stop bar to the locking rod. Then, remove the spring lock 5, release the connection between the clamping plate 4 and the fixed horizontal plate 1, remove the clamping plate 4, and then hang the safety hook connected to one end of the flexible cable on the top of the fixed horizontal plate 1. By shaking the winch 83, the flexible cable is wound up, thereby allowing the flexible cable to drive the entire device to rise. By swinging the rod 81, the protruding plates on both sides of the positioning block 11 of the device are controlled to be clamped on the container locking rod. After fixing, the cutting and spraying operation is carried out.
