Description

Technical Field

[0001] The present invention relates to the technical field of sediment sampling, and particularly relates to an airborne sediment sampling device for an aircraft and a control method thereof. Background Art

[0002] With the rapid development of aircraft technology, its applications in industries such as plant protection, line inspection, fire warning, and express delivery are increasing. Due to the simple operation and flexible movement of aircraft, especially rotorcraft, which are basically not restricted by the site, they can play an important role in scientific research on sediment sampling. An aircraft is equipped with a sediment sampling device to customize functions that cannot be achieved by traditional methods, such as repeated sampling at precise locations, simultaneous sampling at multiple points, and continuous sampling for 24 hours. These functions are of great significance to scientific research.

[0003] Currently, the sediment sampling schemes for aircraft are mainly divided into two types. One is to carry a scraping bucket by an aircraft, fly to a predetermined location, lower the height of the aircraft to make the scraping bucket contact the sediment surface, and then control the aircraft to drag the scraping bucket to move and scrape the surface sediment sample. For the case of only requiring a small amount of sediment samples, this method is simple and has advantages such as light weight. However, this method requires the aircraft to lower its height and drag the scraping bucket to move, which has high requirements for the stability of the aircraft and will affect the safety of the entire aircraft water sampling system. The other is to carry a grab dredger by an aircraft, release the grab dredger to the sediment surface after flying to the designated position, and then control the cable of the grab bucket to contract for grabbing and sampling. The existing airborne sediment sampling devices for aircraft have the disadvantages of being unable to meet the sampling volume, affecting the safety of the aircraft, or having a complex structure and large weight.
