Description

Technical Field

[0001] This utility model relates to the technical field of helicopter bucket water collection auxiliary devices, specifically a fire-fighting helicopter bucket water collection auxiliary device. Background Technology

[0002] Air firefighting mainly utilizes firefighting helicopters to extinguish fires such as forest fires, fires at hazardous chemical sites, and fires in villages lacking water sources. The principle is to use helicopters to suspend special onboard water tanks or dry powder containers and drop them directly to the center of the fire to achieve rapid fire suppression. During the process of the helicopter collecting water using the onboard water tanks, the water tanks need to be suspended below the helicopter, and then the helicopter is lowered to sink the water tanks into rivers or lakes to collect water before rising again and flying to the fire site.

[0003] Currently, when firefighting helicopters use buckets for firefighting, the cables are prone to tangling, posing a safety hazard. At the same time, during the water intake process, the inability to accurately control the water level in the bucket often leads to overflow or insufficient water. Therefore, there is an urgent need for an auxiliary device for firefighting helicopter bucket water intake to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide an auxiliary device for water collection from a fire-fighting helicopter bucket, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0029] Reference Figure 1 , Figure 2 and Figure 3This utility model discloses a water-collecting auxiliary device for a fire-fighting helicopter, comprising a water bucket 1, a connecting strap 2 at the top of the water bucket 1, a cable 3 at the top of the connecting strap 2, a buffer device 4 on the outside of the cable 3, a mounting ring 5 around the buffer device 4, a limit frame 6 on the outside of the mounting ring 5, a guide rod 7 inside the limit frame 6, a guide block 8 and a return spring 9 on the outside of the guide rod 7, a slide cylinder 10 inside the guide block 8, support rods 11 at both ends of the slide cylinder 10, and wear-resistant rings 12 on the outside of the support rods 11. In this embodiment, the water bucket 1 serves to transport water, the connecting strap 2 serves to limit movement, and the cable 3 serves to connect the helicopter.

[0030] Reference Figure 1 The water bucket 1 is provided with a connecting frame 13 inside, and a connecting rod 14 is provided inside the connecting frame 13. A support frame 15 is provided at one end of the connecting rod 14. The two ends of the connecting rod 14 are rotatably connected to the inside of the connecting frame 13 and the limiting frame, respectively. In this embodiment, the connecting frame 13 and the support frame 15 facilitate the rotation of the support rod 15, and the connecting rod 14 supports the opening of the water bucket 1.

[0031] Reference Figure 2 and Figure 3 The cable 3 is slidably connected to the inside of the slide cylinder 10, the guide block 8 is slidably connected to the outside of the guide rod 7, and the reset spring 9 is movably connected to the outside of the guide rod 7. In this embodiment, the slide cylinder 10 plays the role of straightening the cable 3, the guide rod 7 plays the role of limiting the position, and the guide block 8 plays the role of transmission.

[0032] Reference Figure 1 and Figure 4 The connecting frame 13 is equipped with a monitoring device 16. The monitoring device 16 includes a mounting cylinder 17. The mounting cylinder 17 has a through hole 18 inside. A transmission rod 19 is installed inside the through hole 18. A float ball 20 is installed at the bottom of the transmission rod 19. A conical cylinder 21 is installed at the top of the transmission rod 19. A sensor 22 is installed at the top of the conical cylinder 21. A receiver 23 is installed at the top of the sensor 22. An indicator light 24 is installed at the top of the receiver 23. In this embodiment, the mounting cylinder 17 serves as a limit, the through hole 18 facilitates the sliding of the transmission rod 19, and the conical cylinder 21 prevents the transmission rod 19 from falling off.

[0033] Reference Figure 1 and Figure 4 The mounting cylinder 17 is snapped into the inside of the connecting frame 13, the transmission rod 19 is movably connected into the inside of the through hole 18, the conical cylinder 21 is movably connected into the inside of the mounting cylinder 17, the sensor 22 is adapted to the receiver 23, the receiver 23 is snapped into the inside of the mounting cylinder 17. In this embodiment, the sensor 22 plays the role of triggering the receiver 23, and the receiver 23 plays the role of controlling the switch of the indicator light 24.

[0034] The implementation principle of this embodiment is as follows:

[0035] During the process of the helicopter carrying the water bucket 1 to collect water, a certain impact force will be generated instantaneously when the water bucket 1 touches the water surface. At this time, the slide cylinder 10 slides quickly on the outside of the cable 3, so that the cable 3 is quickly separated, which can effectively prevent the cable 3 from getting tangled. The guide block 8 will slide on the outside of the guide rod 7 and compress the return spring 9. Then, the helicopter will carry the water bucket 1 to move upward. During the process of lifting the bucket, the return spring 9 will slowly restore its deformation and push the slide cylinder 10 to return to its original position. After the water in the water bucket 1 is discharged, the weight of the water bucket 1 will drop rapidly. At this time, the cable 3 cannot be in a taut state, and the return spring 9 will fully restore its deformation. The mounting ring 5 and the limit frame 6 will move upward again.

[0036] During the process of drawing water from bucket 1, water will be quickly poured into the interior of bucket 1. Subsequently, when the water reaches the set water level, it will contact the float 20 and cause the float 20 to move upward. Using the transmission rod 19 and the conical cylinder 21, the sensor 22 will be pushed upward. After the receiver 23 and the sensor 22 have moved a certain distance, the indicator light 24 will turn on red to inform the pilot that the water level inside bucket 1 has met the requirements and the pilot can take off (if the water level inside bucket 1 has not met the takeoff standard, the indicator light 24 will not turn on).

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] The combination of the slide cylinder 10, support rod 11, and wear-resistant ring 12 facilitates quick and easy straightening of the cable 3. The combination of the guide block 8, guide rod 7, and return spring 9 reduces the impact force of the cable 3 becoming taut. The combination of the mounting ring 5 and the limiting frame 6 provides a limiting function. By using the above structure, the cable 3 can be effectively prevented from tangling. The combination of the float 20 and the transmission rod 19 provides the water level height. The addition of the conical cylinder 21 facilitates the shaking of the transmission rod 19. The combination of the receiver 23 and the sensor 22 provides the water level data. The addition of the indicator light 24 facilitates monitoring. By using the above structure, the water level in the water tank 1 can be clearly observed.

[0039] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
