Description

Technical Field

[0001] This utility model belongs to the field of fire-fighting helicopter technology, and in particular, it is a water intake device for fire-fighting helicopters. Background Technology

[0002] High-altitude firefighting primarily utilizes firefighting helicopters to extinguish forest fires, fires at hazardous chemical sites, and fires in villages lacking water sources. The principle involves using a helicopter to suspend specialized onboard water tanks or dry powder containers, which are then airdropped directly to the center of the fire for rapid extinguishing. During the water collection process, the water tanks are suspended below the helicopter, which then lowers itself to a river or lake to collect the water before ascending again and flying to the fire site.

[0003] Current water collection devices used by firefighting helicopters cause the water buckets to float on the water surface when collecting water, making it difficult for them to sink. This results in low water collection efficiency and affects firefighting efficiency.

[0004] Therefore, in view of this situation, there is an urgent need to design and produce a water intake device for firefighting helicopters to meet the needs of actual use. Utility Model Content

[0005] The purpose of this invention is to provide a water intake device for firefighting helicopters to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water intake device for a fire-fighting helicopter, comprising a water intake bucket similar to that used by the fire-fighting helicopter, an air pump for removing air from the upper side of the water intake bucket, a water pump for filling the water intake bucket with water on the side of the water intake bucket, a first fixing plate fixedly connected to the inner side of the water intake bucket, a telescopic rod fixedly connected to the upper side of the first fixing plate, a base fixedly connected to the extended end of the telescopic rod, and a counterweight fixedly connected inside the base.

[0007] Preferably, a locking block is fixedly connected to the upper side of the base, and a first annular sealing ring is connected to the upper side of the base.

[0008] Preferably, a water touch sensor is fixedly connected to the lower side of the base, and a remote control panel is installed on the upper side of the water bucket.

[0009] Preferably, a connecting strap is fixedly connected to the upper side of the water bucket, and a slot for engaging with the card block is provided on the inner side of the water bucket.

[0010] Preferably, a second sealing ring is fixedly connected to the lower side of the water bucket, and a limit rod is slidably connected to the side of the first fixing plate.

[0011] Preferably, a second limiting plate is fixedly connected to the upper side of the limiting rod, and a first limiting plate that is fixed to the inner side of the water bucket is slidably connected to the side of the second limiting plate.

[0012] Preferably, the side of the limiting rod is fixed to the base, and the side of the first limiting plate is slidably connected to the extended end of the telescopic rod.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] The water intake device used in this firefighting helicopter activates a telescopic rod to lower the base after the water sensor detects water. At the same time, an air pump is activated to expel air from the water intake bucket, reducing buoyancy. After air is expelled, water can enter the bucket more easily. Simultaneously, a water pump is activated to fill the bucket, accelerating the water collection speed. This prevents excessive air inside the bucket and ensures that the center of gravity is not at the bottom, which would make it difficult for the inlet to contact the water surface and affect the water collection rate.

[0024] To address the issue of water buckets floating on the surface and failing to sink, resulting in low water collection efficiency and impacting firefighting effectiveness, as follows: Figures 1 to 3 The water intake device for a fire-fighting helicopter shown includes a water intake bucket 1, which is the same as the water intake bucket for fire-fighting helicopters. An air pump 5 for removing air from the water intake bucket 1 is installed on the upper side of the water intake bucket 1. A water pump 6 for filling the water intake bucket 1 with water is installed on the side of the water intake bucket 1. A first fixing plate 15 is fixedly connected to the inner side of the water intake bucket 1. A telescopic rod 9 is fixedly connected to the upper side of the first fixing plate 15. A base 2 is fixedly connected to the extended end of the telescopic rod 9. A counterweight block 12 is fixedly connected inside the base 2.

[0025] A locking block 11 is fixedly connected to the upper side of the base 2, and a circular first sealing ring 10 is connected to the upper side of the base 2. A water contact sensor 3 is fixedly connected to the lower side of the base 2. A remote control panel 7 is installed on the upper side of the water bucket 1. A water contact sensor 3 is installed on the upper side inside the water bucket 1. After the water bucket 1 is filled with water, the telescopic rod 9 can be activated to move the base 2 and seal the water bucket 1. A connecting strap 4 is fixedly connected to the upper side of the water bucket 1. The inner side of the water bucket 1 is provided with a slot 14 that engages with the card block 11. The lower side of the water bucket 1 is fixedly connected with a second sealing ring 13. The side of the first fixing plate 15 is slidably connected with a limit rod 8.

Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0028] Working principle

[0029] The water collection device for the firefighting helicopter works as follows: When the water collection bucket 1 is placed in water, the water contact sensor 3 activates the telescopic rod 9 to lower the base 2. At the same time, the air pump 5 is activated to expel the air from the water collection bucket 1, reducing the buoyancy inside the bucket. Simultaneously, the water pump 6 is activated to fill the water collection bucket 1 with water, accelerating the water collection speed. Meanwhile, the limit rod 8 prevents the telescopic rod 9 from being damaged by lateral forces. After the water collection is complete, the telescopic rod 9 is activated to move the base 2 upward, sealing the water collection bucket 1.
