Background

With the rapid development of aircraft technology, the aircraft technology is increasingly applied to industries such as plant protection, line inspection, fire early warning, express delivery and the like. Because the aircraft is simple to operate and flexible to move, particularly a rotary wing aircraft, the aircraft is basically not limited by sites, and can play an important role in scientific research of seawater sampling. The aircraft carries on sea water sampling device, and the customization realizes accurate place repeated sampling, multiple spot simultaneous sampling, 24 hours incessant sampling etc. traditional methods can't realize the function. These functions are of great significance to marine science research.

Current seawater sampling schemes for aircraft on-board are largely divided into two types. One is to mount a water bottle on an aircraft, fly the water bottle to a predetermined place, and lower the aircraft to lower the water bottle to sea water for sampling. For the condition that only a small amount of seawater sample is needed, the method has the advantages of simplicity, light weight and the like. However, the method needs the aircraft to reduce the height so as to take water from the water bottle, has high requirement on the stability of the aircraft, and has heavy weight of the sampling device, thereby affecting the safety of the whole aircraft water sampling system. The other is to carry a water pump, release the water pump to the sea water, and draw the sea water into a sampling bottle carried by the aircraft. The method is suitable for collecting seawater samples with different weights. However, the existing water pump type seawater sampling device in the market has the problems that the weight is large, the sampling height is limited by the power of the water pump, the seawater sampling amount and the sampling depth cannot be accurately controlled, and the like.
