Submerged plant collection clamp

Abstract

The invention provides a submerged plant collection clamp capable of determining a sampling quadrat area. The submerged plant collection clamp is suitable for collecting a lakebed submerged plant sample. The submerged plant collection clamp comprises two mutually-symmetrical bending clamps capable of being freely opened and closed, wherein each bending clamp comprises clamp teeth, a connecting rod, a force bearing plate and a handle from the bottom to top, and the submerged plant collection clamp can be controlled by a spiral iron core on the inner side of each force bearing plate to be opened or closed. Cutting wires fixed on the bottoms of the clamp teeth are used for separating button mud inside and outside a quadrat and at the bottom of a plant. The submerged plant collection clamp has the advantages of simple structure, convenience in operation, controllable quadrat area, and capability of ensuring the integrity of the plant.

Description

technical field [0001] The invention relates to a submerged plant collecting pliers capable of determining the size of a sampling square, and can effectively ensure the integrity of the collected plants. Background technique [0002] In order to effectively manage and protect lakes, comprehensive monitoring of animals, plants and water quality in water bodies is an important part of wetland protection work. Especially in recent years, with the overgrowth of aquatic plants, more and more scholars have devoted themselves to the research of lake swamp control. In order to ensure the accuracy of the research data, on-site sampling has become particularly important, not only to ensure the accuracy of the biomass in the sample, but also to collect the roots, stems and leaves of the plants completely. The utility model patent with the notification number CN 2738232Y discloses an arc clamping arm type submerged plant sampler, which collects submerged plants by closing the T-shaped ...

Problems solved by technology

The above collection devices often ignore the effective collection of the root system of submerged plants. Since the tissues and organs of submerged plants are relatively weak, direct extraction of plants through the collector will cause great damage to the root system.
