Description

Submerged plant sampler

Technical Field

The utility model relates to a field that aquatic plant gathered, concretely relates to benthophyte sampler.

Background

In order to effectively manage and protect wetlands such as rivers, lakes and the like, comprehensive monitoring of submerged plants in water is important content in protection work, and the submerged plants as primary producers in water ecosystems play an important role in material circulation and energy flow of the water ecosystems, so that biomass of the submerged plants is often used as an important parameter for evaluating stability of the water systems such as rivers, lakes and the like. In recent years, as the research on the functionality of submerged plants continues, more and more scholars pay more attention to the efficient collection method of the submerged plants. In the past, submerged plants collected during investigation of rivers and lakes mainly utilize artificial water cutting, towing hooks, iron clamps with long handles (similar to river mud) and the like, and are complex to operate and low in efficiency. Traditional grab bucket type grass collector does not have the stereoplasm action bars that stretches into aquatic, needs the throwing, and the sampling point is unset, and the quality is heavier, and the operation is hard. Traditional grab bucket type grass collector does not have stereoplasm connecting rod, can only be to the sampling of the loose water of bed mud, and the river course bed mud is complicated various because artificial interference's reason, often contains hard materials such as stone, building rubbish, can't snatch submerged plant. Traditional pasture and water clamp gets appearance ware does not have stereoplasm action bars, though the quality is lighter, easy operation, and the sampling is difficult, and efficiency is lower, and the sample of gathering is difficult to embody the objective current situation of sample plot, and the practicality of sampling and investigation to the water that distributes large tracts of land submerged plant is lower. The traditional device often ignores the effective collection to the submerged plant, because the tissue organ of submerged plant is more delicate, directly pulls out the plant through the collector and can cause great destruction to the root system, influences the growth and the recovery of submerged vegetation.

Chinese patent No. CN205389486U relates to a multifunctional submerged plant collector. The working principle is that the driving arm is pulled by a steel wire rope by pulling a hand brake handle to drive the driven arm, so that the L-shaped clamps are mutually engaged; thereby clamping the submerged plants and dragging the sampler to leave the water surface. However, when the device is used, the upper end of the sampling arm and the steel wire rope are respectively grabbed by two hands, the operation is laborious, the L-shaped clamp cannot be adjusted, the sampling area cannot be controlled, and the relationship between the sampling area and the plant cannot be quantified. And this patent can't be flexible, dismantle the person in charge, and the collection degree of depth is limited, is not convenient for work to carry.
