Technical Field

[0001] This utility model relates to the field of helicopter fire extinguishing bucket technology, specifically a helicopter fire extinguishing bucket with an adjustment mechanism. Background Technology

[0002] A helicopter fire bucket is a specialized device used for firefighting missions. It typically consists of a large-capacity water tank and a suspension system, which can be mounted under or to the side of a helicopter. When a fire occurs, the helicopter can fly to the vicinity of the fire and use the fire bucket to release a large amount of water or extinguishing agent above the fire. This operation can quickly cover a large area of ​​fire, and the amount and range of water sprayed can be controlled through the design and operation of the bucket.

[0003] Current equipment can only carry a fixed amount of water and cannot be adjusted according to the actual situation. When the fire is too small, carrying a large amount of water will waste helicopter fuel and water resources, thus reducing the scope of application of the equipment. Therefore, there is an urgent need for a helicopter fire-fighting bucket with an adjustment mechanism to improve the above problems. Utility Model Content

[0034] Reference Figure 1 ,and Figures 4 to 7 The adjusting mechanism 11 includes a movable block 12. A connecting plate 13 is provided at the bottom of the movable block 12. In this embodiment, the connecting plate 13 is fixedly connected to the movable block 12. A first connecting rod 14 is provided inside the connecting plate 13, allowing it to rotate. A second connecting rod 15 is provided at the bottom of the first connecting rod 14, also allowing it to rotate. A rotating block 16 is provided at the end of the second connecting rod 15 away from the first connecting rod 14, and is fixedly connected to the second connecting rod 15. A connecting block 17 is provided on the outer surface of the rotating block 16, connecting to... The fire extinguishing bucket 1 is fixedly connected, and its water capacity can be adjusted, thereby expanding the applicability of the equipment. The moving block 12 has a circular hole 18 inside, which is adapted to the rotating rod 7. The rotating rod 7 is slidably connected to the circular hole 18, which allows the moving block 12 to move, thereby driving the first connecting rod 14 and the second connecting rod 15 to rotate, thereby changing the shape of the fire extinguishing bucket 1, adjusting its water capacity, and thus expanding the applicability of the equipment.

[0035] Reference Figure 1 ,and Figures 4 to 7The top of the movable block 12 is provided with a positioning pin 19, and the outer surface of the rotating rod 7 is provided with a positioning hole 20. The positioning pin 19 is adapted to the positioning hole 20 and is threadedly connected to the positioning hole 20, which can fix the movable block 12 and thus fix the shape of the fire extinguishing bucket 1. The interior of the second connecting rod 15 is provided with a sliding groove 21, and the end of the first connecting rod 14 near the second connecting rod 15 is provided with a limiting plate 22. In this embodiment, the limiting plate 22 is fixedly connected to the second connecting rod 15, the sliding groove 21 is adapted to the first connecting rod 14, and the first connecting rod 14 is slidably connected to the sliding groove 21, which can move the first connecting rod 14, thereby changing the shape of the fire extinguishing bucket 1, adjusting the water carrying capacity of the fire extinguishing bucket 1, and expanding the applicability of the equipment.

[0036] Reference Figure 1 ,and Figures 4 to 7 The outer surface of the first connecting rod 14 is provided with a limiting hole 23, and the outer surface of the second connecting rod 15 is provided with a limiting pin 24. The limiting hole 23 is adapted to the limiting pin 24, and the limiting pin 24 is threadedly connected to the limiting hole 23, which can fix the first connecting rod 14 and thus adjust the total length of the first connecting rod 14 and the second connecting rod 15.

The inner surface of the first connecting rod 14 and the second connecting rod 15 is provided with a through hole 26, which is adapted to the rotating shaft 25, and the rotating shaft 25 is rotatably connected to the through hole 26, which can make the first connecting rod 14 and the second connecting rod 15 rotate, thereby changing the shape of the fire extinguishing bucket 1, adjusting the water carrying capacity of the fire extinguishing bucket 1, and thus expanding the applicability of the equipment.

[0037] The implementation principle of this embodiment is as follows:

[0038] The helicopter fire extinguishing bucket with an adjustment mechanism 11 is equipped with such a mechanism. When using the device, the operator rotates the positioning pin 19, which moves the movable block 12. The operator then moves the movable block 12. Because the movable block 12 has a circular hole 18 inside, the rotating rod 7 can slide inside the circular hole 18, thus moving the movable block 12. The movement of the movable block 12 drives the connecting plate 13 to move, and the movement of the movable block 12 drives one end of the first connecting rod 14 to move. Because the first connecting rod 14 has a circular hole inside... There is a through hole 26, and the rotating shaft 25 can rotate inside the through hole 26, thereby causing the first connecting rod 14 to rotate. The rotation of the first connecting rod 14 can drive the second connecting rod 15 to rotate. Since the second connecting rod 15 also has a through hole 26 inside, it can rotate. Since the total length of the first connecting rod 14 and the second connecting rod 15 remains unchanged, one end of the second connecting rod 15 can move, thereby driving the connecting block 17 to move. Since the connecting block 17 is fixedly connected to the fire extinguishing bucket 1, it can... The connecting block 17 moves the fire extinguishing bucket 1, thereby changing its shape and adjusting its water capacity. By rotating the limiting pin 24, the first connecting rod 14 is released from its limit. Since the second connecting rod 15 has a groove 21 inside, the first connecting rod 14 can slide within the groove 21, allowing it to move and thus adjusting the total length of the first and second connecting rods 14 and 15. This further adjusts the water capacity of the fire extinguishing bucket 1. After adjustment, the operator rotates the positioning pin 19 and the limiting pin 24. The positioning pin 19 enters the positioning hole 20, thereby fixing the moving block 12. The limiting pin 24 enters the limiting hole 23, thereby fixing the first connecting rod 14. This fixes the shape of the fire extinguishing bucket 1 and adjusts the water capacity of the fire extinguishing bucket 1. The equipment can be adjusted according to the actual situation, thus expanding its applicable range. After adjustment, the operator can use the fire extinguishing bucket 1 to pump water for fire extinguishing.

[0039] Compared with the prior art, the present invention has the following advantages:

[0040] The helicopter fire extinguishing bucket with adjustment mechanism is equipped with adjustment mechanism 11. By moving the first connecting rod 14, the overall length of the first connecting rod 14 and the second connecting rod 15 can be adjusted. By moving the moving block 12, the connecting block 17 can be moved, thereby changing the shape of the fire extinguishing bucket 1, adjusting the water volume, and adjusting according to the actual situation, avoiding waste of resources and expanding the applicability of the equipment.
