Abstract

The invention relates to an unmanned aerial vehicle type automatic sampling system at fixed points of the water surface. The unmanned aerial vehicle type automatic sampling system comprises a water sampler, a lifting mechanism and a control circuit, wherein the water sampler comprises a barrel body and a periphery component, a large conical horn mouth is designed at the lower end of the barrel body, and an end cover exhaust device is arranged at the upper end of the barrel body; a buoyancy ring and a heavy ring are arranged at the outer side of the barrel body, the buoyancy ring is arranged at the lower end of an end cover, and the heavy ring is arranged at the lower end of the buoyancy ring; and a valve cover is arranged at the bottom of the inner side of the barrel body; the integrity is connected by a flying ring, the lifting mechanism is connected at the upper part of the flying ring, and is controlled by the control circuit. The lifting mechanism adopts a winding and distributing mechanism, the winding mechanism is composed of a power motor, a worm-gear speed reducer and a speed ratio guide wire wheel set, the speed ratio guide wire wheel set is connected with the flying ring by a connecting wire, the speed ratio guide wire wheel set is connected with the worm-gear speed reducer which is connected with the power motor; while the twisting force is increased, self locking can be achieved; and the system adopts the unmanned aerial vehicle system to realize sampling, the traditional manual sampling mode can be replaced completely, and rapid, intelligent and high-efficiency water sampling can be achieved.

Description

technical field [0001] The invention relates to a fixed-point automatic sampling system for an unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicles. Background technique [0002] Surface seawater sampling is an important part of marine environmental monitoring. The purpose is to collect oil film floating on the water surface, analyze its composition and find out the source of oil spill. At present, the seawater sampling method is mainly manual sampling, that is, large-scale observation and sampling by ships. For example, after the ship reaches the target sea area, the seawater collection is realized by manually releasing water collection devices (such as Nansen collectors or card cover collectors, etc.) sampling. [0003] Although there are many types of manual sampling, the control methods are similar. The water collector is put into the water. By releasing the heavy hammer, the heavy hammer triggers the elastic switch of the water collecto...
