Description

Technical Field

[0001] This application relates to the field of fire-fighting equipment technology, and in particular to helicopter water cannon fire extinguishing systems. Background Technology

[0002] Helicopters are frequently used as firefighting equipment, especially during wildfires or other large-scale fires. To facilitate firefighting, helicopters are often equipped with water cannons. These types of helicopters are commonly referred to as "seaplanes" or "aerial fire trucks." They can transport large quantities of water to the fire scene and use water cannons to spray water onto the fire. The water cannons are usually located at appropriate positions on the bottom or fuselage of the helicopter to ensure that the sprayed water or foam effectively covers the fire area.

[0003] Helicopter water cannons typically spray water to extinguish fires. Water is the most common fire extinguishing substance because it can quickly reduce the intensity of a fire and cool the surface of burning materials. The water cannon sprays a large amount of water mist onto the fire scene through high-pressure jets to extinguish the fire. In addition to water, flame retardants can also be added to the water tank for fire extinguishing. These flame retardants can inhibit the combustion process of the flames and reduce the risk of the fire spreading, thus playing a role in extinguishing the fire.

[0004] In firefighting operations, helicopters have become a common tool, as they can quickly deliver large amounts of water to the fire scene. However, most existing water cannon systems have fixed muzzle directions, allowing them to spray water only in specific directions. This makes it difficult to flexibly respond to changes in the location of the fire source and the path of fire spread. When multiple directions or areas need to be covered, the helicopter's flight path or spray angle may need to be adjusted to cover different areas, increasing the complexity of operations and the difficulty of firefighting. Summary of the Invention

[0005] The purpose of this application is to address the problem that existing methods may require adjusting the helicopter's flight path or spray angle to cover different areas when multiple directions or regions need to be covered, which increases the complexity of operation and the difficulty of fire extinguishing. This application provides a helicopter water cannon fire extinguishing system.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A helicopter water cannon fire extinguishing system includes a mounting platform. A connecting column is fixedly connected to one side of the top of the mounting platform, and the top of the connecting column is fixedly connected to the bottom of the helicopter. Connecting plates are fixedly connected to both sides of the bottom of the mounting platform, and water tanks are fixedly connected to the bottom ends of the connecting plates on both sides. A water outlet pipe is fixedly connected to one side of the bottom of the water tank and is connected to the water tank. A water inlet pipe is fixedly connected to the upper side of the water tank away from the water outlet pipe and is connected to the water tank. A mounting frame is provided on one side of the mounting platform. A rotating rod is rotatably connected inside the mounting frame. A fixed cylinder is fixedly connected to one side of the rotating rod. The water cannon body is located inside the fixed cylinder. A connecting pipe is fixedly connected to one side of the fixed cylinder. One end of the connecting pipe is connected to the water cannon body, and the other end of the connecting pipe is connected to the water outlet pipe. An adjustment mechanism is provided on one side of the top of the mounting platform. A reciprocating mechanism is provided on one side of the inside of the water tank. A stirring mechanism is provided on one side of the water tank.

[0008] By adopting the above technical solution, the staff first fly the helicopter to the fire site. Then, the water in the water tank is pumped out to the outlet pipe by the water pump. The outlet pipe is then connected to the connecting pipe so that the water in the water tank can flow into the water cannon. The water cannon will then extinguish the fire. The angle of the water cannon is changed by the adjustment mechanism. After the fire is extinguished, clean water can be added from the inlet pipe. At the same time, cleaning agent can be added. Then the stirring mechanism is started to clean the inner wall of the water tank.

[0009] Furthermore, the adjustment mechanism includes a slot formed on one side of the top of the mounting platform. A drive motor is installed inside the slot and is fixedly connected to the inner bottom wall of the slot. A rotating rod is fixedly connected to the output end of the drive motor. The top side of the rotating rod is fixedly connected to the bottom of the mounting frame. A gear is fixedly connected to the outer surface of one side of the output end of the drive motor.

[0010] By adopting the above technical solution, the drive motor is started to drive the rotating rod to rotate, which in turn drives the mounting frame to rotate. The movement of the mounting frame changes the angle of the water cannon. By adjusting the angle left and right, the water can be sprayed in different directions.

[0011] Furthermore, a crossbar is fixedly connected to one side of the drive motor output end above the gear, and an electric telescopic rod is fixedly connected to one side of the top of the crossbar. A rotating seat is rotatably connected to the top of the electric telescopic rod, and a sliding groove is provided at the bottom of the fixed cylinder. The top of the rotating seat is slidably connected to the sliding groove.

[0012] By adopting the above technical solution, the rotating seat is raised by starting the electric telescopic rod. When the rotating seat rises, it will lift the fixed cylinder. At the same time, the rotating seat will slide inside the slide groove, thereby raising the fixed cylinder and adjusting the height and orientation of the water cannon, further improving the fire extinguishing effect.

[0013] Furthermore, a second sliding groove is provided on one side of the top of the mounting platform. The second sliding groove is arc-shaped, and a sliding rod is fixedly connected to one side of the bottom of the crossbar. The bottom of the sliding rod is slidably connected to the second sliding groove.

[0014] By adopting the above technical solution, the slider and the slide can provide a smooth motion trajectory, making the left and right adjustment device more stable and precise when adjusting the angle.

[0015] Furthermore, the reciprocating mechanism includes a second gear meshing with one side of the first gear. A drive rod is fixedly connected to the bottom of the second gear. The bottom of the drive rod passes through the water tank and is rotatably connected to the inner bottom wall of the storage box. A striking rod is fixedly connected to one side of the drive rod. One side of the storage box is set as an opening. A connecting block is provided at the opening of the storage box. A sealing gasket is provided between the connecting block and the storage box. The striking rod abuts against the connecting block.

[0016] By adopting the above technical solution, the left and right swing of the rotating rod one drives the gear one to rotate, the gear one drives the gear two to rotate, the gear two causes the drive rod to rotate, and the drive rod in turn drives the striking rod to rotate. When the striking rod rotates, it will abut against the connecting block. After being impacted, the connecting block will move to one side, causing a gap to appear between the connecting block and the storage box. The flame retardant will pass through the gap under the action of gravity and fall into the water tank to mix with the water.

[0017] Furthermore, horizontal blocks are slidably connected to both sides of the connecting block. The side of the horizontal block closest to the storage box penetrates the storage box. Limiting blocks are fixedly connected to the bottom of the horizontal blocks on both sides. Vertical plates are fixedly connected to the side of the horizontal blocks on both sides away from the storage box. Cavities are opened on both sides of the bottom of the storage box. Reset blocks are slidably connected inside the cavities. The end of the reset block away from the cavity is fixedly connected to the connecting block. The top side of the reset block is fixedly connected to a compression block. A spring telescopic rod is fixedly connected to one side of the compression block. The side of the spring telescopic rod away from the compression block is fixedly connected to the inner wall of the storage box.

[0018] By adopting the above technical solution, when the connecting block moves to one side, it will drive the vertical plate to move to one side, and the vertical plate will drive the reset block to move to one side. When the reset block moves to one side, the compression block will squeeze the spring telescopic rod. After the spring telescopic rod is squeezed, it will generate elastic potential energy. When the striking rod rotates to a certain extent and no longer contacts the connecting block, the elastic potential energy of the spring telescopic rod will drive the compression block to reset. The compression block drives the reset block to reset, and the reset block will then drive the connecting block to press against the storage box, and seal it through the sealing gasket.

[0019] Furthermore, a slider is fixedly connected to the bottom of the reset block, and a three-slide groove is provided on the inner bottom wall of the cavity. The slider and the three-slide groove are matched in shape, and the slider and the three-slide groove are slidably connected.

[0020] By adopting the above technical solution, the cooperation between the slider and the groove enables the reset block to slide stably, reducing errors and instability.

[0021] Furthermore, the stirring mechanism includes a rotary motor fixedly connected to one side of the water tank. The output end of the rotary motor passes through the water tank and is fixedly connected to a rotating rod. Several stirring rods are fixedly connected to both sides of the rotating rod, and a scraper is fixedly connected to the side of one stirring rod closest to the inner wall of the water tank.

[0022] By adopting the above technical solution, the drive motor is started, which drives the rotating rod to rotate. The rotating rod will drive the agitator to rotate. After stirring, the agitator can evenly disperse the flame retardant in the water, ensuring that the concentration of the flame retardant in the water is uniform. This can improve the efficiency of the flame retardant contacting the fire source.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. When adjusting the angle of the water cannon, the drive motor is started to rotate the rotating rod, which in turn rotates the mounting bracket. The movement of the mounting bracket changes the angle of the water cannon. At the same time, when it is necessary to adjust the height of the water cannon, the electric telescopic rod is started to change the direction of the water cannon. By adjusting the angle, the water can be sprayed in different directions to meet the needs of different fire scenes. The water can be sprayed to the specific location or danger zone that needs to be extinguished. Flexible angle adjustment can better adapt to the changes and spread of the fire and improve the fire extinguishing effect.

[0025] 2. In this application, when flame retardant needs to be added, the left and right swing of the rotating rod one drives the gear one to rotate, the gear one drives the gear two to rotate, the gear two causes the drive rod to rotate, and the drive rod drives the striking rod to rotate. When the striking rod rotates, it will abut against the connecting block. After being impacted, the connecting block will move to one side, so that a gap appears between the connecting block and the storage box. The flame retardant will pass through the gap under the action of gravity and fall into the water tank to mix with the water. Then the water cannon will spray out the mixed water, thereby improving the fire extinguishing efficiency.

[0026] 3. In this application, when mixing the flame retardant and water, the drive motor is started, which drives the rotating rod to rotate. The rotating rod drives the agitator to rotate, and after stirring, the agitator can evenly disperse the flame retardant in the water, ensuring that the concentration of the flame retardant in the water is uniform. This can improve the efficiency of the flame retardant contacting the fire source, and at the same time, reduce the risk of flame retardant precipitation. After the fire is extinguished, clean water and cleaning agent are added at the water inlet pipe, and the agitator is started to rotate. The agitator drives the scraper to clean the inner wall of the water tank. Cleaning the inner wall of the water tank can remove impurities and residues attached to the wall surface, reduce the growth of bacteria, and help maintain the normal operation of the water tank equipment.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figures 1 to 7 This application will be described in further detail.

[0037] This application discloses a helicopter water cannon fire extinguishing system.

[0038] Reference Figure 1 and Figure 2 The helicopter water cannon fire extinguishing system includes a mounting platform 1. A connecting column 2 is fixedly connected to one side of the top of the mounting platform 1. The top of the connecting column 2 is fixedly connected to the bottom of the helicopter. Connecting plates 3 are fixedly connected to both sides of the bottom of the mounting platform 1. Water tanks 4 are fixedly connected to the bottom ends of the connecting plates 3. A water outlet pipe 5 is fixedly connected to one side of the bottom of the water tank 4. The water outlet pipe 5 is connected to the water tank 4. A water inlet pipe 6 is fixedly connected to the upper side of the water tank 4 away from the water outlet pipe 5. The water inlet pipe 6 is connected to the water tank 4. A water cannon is installed on one side of the mounting platform 1. A mounting frame 9 is provided, and a rotating rod 10 is rotatably connected inside the mounting frame 9. A fixed cylinder 11 is fixedly connected to one side of the rotating rod 10. A water cannon body 13 is installed inside the fixed cylinder 11. A connecting pipe 12 is fixedly connected to one side of the fixed cylinder 11. One end of the connecting pipe 12 is connected to the water cannon body 13, and the other end of the connecting pipe 12 is connected to the water outlet pipe 5 (not shown in the figure). An adjustment mechanism is provided on one side of the top of the mounting platform 1. A reciprocating mechanism is provided on one side of the interior of the water tank 4. A stirring mechanism is provided on one side of the water tank 4.

[0039] When extinguishing a fire, the first step is for staff to fly a helicopter to the fire location. Then, a water pump draws water from water tank 4 into outlet pipe 5, which is then connected to connecting pipe 12, allowing the water in water tank 4 to flow into the water cannon body 13. The water cannon body 13 then extinguishes the fire. By adjusting the angle of the water cannon body 13 using the adjustment mechanism, the water can be accurately aimed at the fire source or areas with large fires, increasing the extinguishing effect. When the adjustment mechanism moves, it drives the reset mechanism to move, which releases flame retardant into water tank 4, improving the extinguishing effect. During the release process, a stirring mechanism can be activated to agitate the water in water tank 4, thereby increasing the mixing degree between the flame retardant and the water. After extinguishing the fire, clean water and cleaning agent can be added through inlet pipe 6, and the stirring mechanism can be activated to clean the inner wall of water tank 4. Finally, the cleaned water is discharged from the water cannon, making it easier to use.

[0040] Reference Figure 1 and Figure 2 The adjustment mechanism includes a slot on one side of the top of the mounting platform 1. A drive motor 7 is installed inside the slot. The drive motor 7 is fixedly connected to the inner bottom wall of the slot. A rotating rod 8 is fixedly connected to the output end of the drive motor 7. The top side of the rotating rod 8 is fixedly connected to the bottom of the mounting frame 9. A gear 38 is fixedly connected to the outer surface of one side of the output end of the drive motor 7.

[0041] When the angle of the water cannon needs to be adjusted, the drive motor 7 is started to drive the rotating rod 8 to rotate. The rotating rod 8 will drive the mounting frame 9 to rotate. The movement of the mounting frame 9 will change the angle of the water cannon. By adjusting the angle left and right, the water can be sprayed in different directions to meet the needs of different fire scenes. The water can be sprayed to the specific location or dangerous area that needs to be extinguished. The flexible adjustment of the angle can better adapt to the changes and spread of the fire and improve the fire extinguishing effect.

[0042] Reference Figure 1 and Figure 2 A crossbar 14 is fixedly connected to one side of the output end of the drive motor 7 above gear 38. An electric telescopic rod 15 is fixedly connected to one side of the top of the crossbar 14. A rotating seat 16 is rotatably connected to the top of the electric telescopic rod 15. A sliding groove 17 is opened at the bottom of the fixed cylinder 11. The top of the rotating seat 16 is slidably connected to the sliding groove 17.

[0043] When the height of the water cannon needs to be adjusted, the electric telescopic rod 15 is activated to drive the rotating seat 16 to rise. When the rotating seat 16 rises, it will lift the fixed cylinder 11. At the same time, the rotating seat 16 will slide inside the slide groove 17, thereby raising the fixed cylinder 11 and adjusting the height of the water cannon. By adjusting the height of the water cannon, the water flow can be accurately aimed at the specific location that needs to be extinguished. Adjustments can be made according to the location and height of the fire source to ensure that the water flow is sprayed to the area that needs to be extinguished the most, thereby further improving the fire extinguishing effect.

[0044] Reference Figure 1 and Figure 2 The top side of the mounting platform 1 is provided with a sliding groove 18, which is arc-shaped. A sliding rod 19 is fixedly connected to the bottom side of the crossbar 14, and the bottom of the sliding rod 19 is slidably connected to the sliding groove 18.

[0045] When adjusting the water cannon left and right, the sliding rod 19 slides inside the slide groove 18. The slider 33 and the slide groove can provide a smooth movement trajectory, making the left and right adjustment device more stable and precise when adjusting the angle.

[0046] Reference Figure 3 and Figure 4 The reciprocating mechanism includes a gear 39 meshing with one side of gear 38. A drive rod 20 is fixedly connected to the bottom of gear 39. The bottom of the drive rod 20 passes through the water tank 4 and is rotatably connected to the inner bottom wall of the storage box 21. A striking rod 22 is fixedly connected to one side of the drive rod 20. One side of the storage box 21 is set as an opening. A connecting block 23 is set at the opening of the storage box 21. A sealing gasket 24 is set between the connecting block 23 and the storage box 21. The striking rod 22 abuts against the connecting block 23.

[0047] When flame retardant needs to be added, the left and right swing of the rotating rod 8 drives the gear 38 to rotate, which in turn drives the gear 39 to rotate. The gear 39 then drives the drive rod 20 to rotate, which in turn drives the striking rod 22 to rotate. When the striking rod 22 rotates, it will contact the connecting block 23. After being impacted, the connecting block 23 will move to one side, creating a gap between the connecting block 23 and the storage box 21. The flame retardant, under the action of gravity, passes through the gap and falls into the water tank 4 to mix with the water. The water cannon body 13 then sprays out the mixed water, thereby improving the fire extinguishing efficiency.

[0048] Reference Figure 5 and Figure 6A horizontal block 25 is slidably connected to both sides of the connecting block 23. The side of the horizontal block 25 near the storage box 21 penetrates the storage box 21. A limit block 26 is fixedly connected to the bottom of the two horizontal blocks 25. A vertical plate 27 is fixedly connected to the side of the two horizontal blocks 25 away from the storage box 21. A cavity 28 is opened on both sides of the bottom of the storage box 21. A reset block 29 is slidably connected inside the cavity 28. The end of the reset block 29 away from the cavity 28 is fixedly connected to the connecting block 23. A compression block 30 is fixedly connected to the top side of the reset block 29. A spring telescopic rod 31 is fixedly connected to one side of the compression block 30. The side of the spring telescopic rod 31 away from the compression block 30 is fixedly connected to the inner wall of the storage box 21.

[0049] When the connecting block 23 moves to one side, it will drive the vertical plate 27 to move to one side, and the vertical plate 27 will drive the reset block 29 to move to one side. When the reset block 29 moves to one side, the compression block 30 will squeeze the spring telescopic rod 31. After the spring telescopic rod 31 is squeezed, it will generate elastic potential energy. When the striking rod 22 rotates to a certain extent and no longer contacts the connecting block 23, the elastic potential energy of the spring telescopic rod 31 will drive the compression block 30 to reset. The compression block 30 will drive the reset block 29 to reset, and the reset block 29 will drive the connecting block 23 to press against the storage box 21. The sealing gasket 24 will seal the inside of the storage box 21, so that the inside of the storage box 21 is sealed. At this time, the flame retardant can be added to the water tank 4 through the inlet tube for future use, reducing the risk that the flame retardant effect will be affected and gradually decrease after being soaked in water for a long time.

[0050] Reference Figure 5 and Figure 6 The bottom of the reset block 29 is fixedly connected to a slider 33, and the inner bottom wall of the cavity 28 is provided with a sliding groove 32. The slider 33 and the sliding groove 32 are matched in shape, and the slider 33 and the sliding groove 32 are slidably connected.

[0051] When the reset block 29 moves, the slider 33 is slidably connected to the slide groove 32. Through the cooperation between the slider 33 and the slide groove, the reset block 29 can slide stably, reducing errors and instability.

[0052] Reference Figure 7 The stirring mechanism includes a rotary motor 34 fixedly connected to one side of the water tank 4. The output end of the rotary motor 34 passes through the water tank 4 and is fixedly connected to a rotating rod 35. Several stirring rods 36 are fixedly connected to both sides of the rotating rod 35. A scraper 37 is fixedly connected to one side of the stirring rod 36 near the inner wall of the water tank 4. The scraper 37 is provided with a clearance position corresponding to the storage box 21, so as to avoid the storage box 21 during rotation.

[0053] After the flame retardant is added to the water tank 4, the drive motor 7 is started, which drives the rotating rod 35 to rotate. The rotating rod 35 drives the agitator to rotate, and the agitator 36 can evenly disperse the flame retardant in the water after stirring, ensuring that the concentration of the flame retardant in the water is uniform. This can improve the efficiency of the flame retardant contacting the fire source, and at the same time, reduce the risk of flame retardant precipitation. After the fire is extinguished, clean water and cleaning agent are added at the water inlet pipe, and the agitator 36 is started to rotate. The agitator 36 drives the scraper 37 to clean the inner wall of the water tank 4. Cleaning the inner wall of the water tank 4 can remove impurities and residues attached to the wall surface, reduce the growth of bacteria, and help maintain the normal operation of the water tank 4 equipment.

[0054] Working principle: First, the staff flies the helicopter to the fire site. Then, the water in the water tank 4 is pumped out to the outlet pipe 5 by the water pump. The outlet pipe 5 is then connected to the connecting pipe 12 so that the water in the water tank 4 can flow into the water cannon. The water cannon will then extinguish the fire. By starting the drive motor 7, the rotating rod 8 will rotate. The rotating rod 8 will drive the mounting frame 9 to rotate. The movement of the mounting frame 9 will change the angle of the water cannon. By adjusting the angle left and right, the water can be sprayed in different directions to meet the needs of different fire scenes and spray the water to the specific location or dangerous area that needs to be extinguished.

[0055] The left and right swing of the rotating rod 8 drives the gear 38 to rotate, which in turn drives the gear 39 to rotate. The gear 39 then drives the drive rod 20 to rotate, which in turn drives the striking rod 22 to rotate. When the striking rod 22 rotates, it will contact the connecting block 23. After being impacted, the connecting block 23 will move to one side, creating a gap between the connecting block 23 and the storage box 21. The flame retardant, under the action of gravity, passes through the gap and falls into the water tank 4 to mix with the water. The water cannon then sprays the mixed water out, thereby improving the fire extinguishing efficiency.
