Description

TECHNICAL FIELD

[0001] The utility model relates to aquatic plant sampling technical field, specifically, relate to a kind of floating type alien invasive aquatic plant unmanned aerial vehicle sampling device. BACKGROUND

[0002] In the early 20th century, some floating type alien aquatic plants were introduced into China. For example, water hyacinth was introduced into provinces in mainland China as a feed crop in the 1930s, and then escaped into the wild. Alien invasive aquatic plants grow rapidly, consume a large amount of oxygen and nutrients in water, and occupy the living space of native aquatic plants, leading to a decrease or even extinction of native aquatic plants and destruction of the structure and function of the original aquatic ecosystem. In order to control the spread and harm of these alien invasive aquatic plants, a large amount of manpower, material resources and financial resources need to be invested for management, including manual salvage, mechanical removal, chemical control, etc. However, the management effect is often difficult to last long and requires long-term investment.

[0003] Most of the existing technologies rely on manual rowing or using fixed equipment on the shore for sampling. For water areas far from the shore, shallow areas with dense waterweeds that are difficult to pass through, and middle positions of large lakes and rivers, personnel are difficult to reach for sampling work, resulting in a large limitation in sampling range and inability to comprehensively cover the entire water area. Some alien invasive aquatic plant samples in special positions may be missed, and the overall distribution of alien invasive aquatic plants in the water area cannot be accurately grasped. When facing a large number of intertwined and randomly growing floating aquatic plants, the existing sampling tools often lack effective means to actively push away the plants. For example, the common mesh bag sampling method is easily entangled by surrounding aquatic plants when it is inserted into water, and the target plant sample cannot be smoothly collected, resulting in blocked sampling work, low success rate, and the collected samples may not be representative and cannot accurately reflect the true situation of alien invasive aquatic plants.
