Vertical lift type alga sporophyte collector

Abstract

The invention discloses a vertical lift type alga sporophyte collector which comprises a vertical collecting barrel, a lower sealing barrel, a clump weight and a pressure triggering and releasing mechanism. Openings are formed in the upper end and the lower end of the vertical collecting barrel, a spore filter screen is arranged in the vertical collecting barrel and is positioned on the lower portion of the vertical collecting barrel, and a buoyancy block is arranged on the outer side surface of the vertical collecting barrel; the lower sealing barrel is used for sealing the opening in the lower end of the vertical collecting barrel, an opening is formed in the upper end of the lower sealing barrel, the lower end of the lower sealing barrel is closed, and the sealed lower end of the vertical collecting barrel extends into the lower sealing barrel from the opening in the upper end of the lower sealing barrel; the clump weight is arranged on the lower sealing barrel. The vertical lift type alga sporophyte collector has the advantages that the vertical lift type alga sporophyte collector is convenient to operate and free of influence of sea current, the accuracy of the locations of the collecting barrel which is downwardly released to water layers at specific depths can be effectively improved, and accordingly the accuracy of research on distribution conditions of alga sporophyte can be improved by the reliable vertical lift type alga sporophyte collector.

Description

technical field [0001] The invention relates to a collector, in particular to a vertical lift type algae sporophyte collector. Background technique [0002] The seaweed farm ecosystem is one of the typical nearshore ecosystems. It uses seaweed to absorb, fix, and transfer carbon, nitrogen, phosphorus and other biogenic elements in seawater to reduce eutrophication in water areas, and at the same time form a local area for the growth and habitat of various marine organisms. A stable niche can achieve the purpose of increasing biodiversity and restoring fishery resources. [0003] In recent years, with the gradual deepening of research on seaweed ecological restoration, some ecological restoration methods are also being adopted, and some results have been achieved. In the research process of seaweed ecological restoration, it is necessary to analyze and study the distribution of sporophytes produced by seaweed. At present, the analysis and research on the distribution of spo...

Problems solved by technology

At present, the operation of this sporophyte is not only inconvenient, but also due to the influence of ocean currents, the collection cylinder may be washed far away in actual collection, causing the rope to tilt, resulting in the inability to determine the specific depth of the collection cylinder when it is lowered into a water layer at a specific depth , affecting the accuracy of people's research on the distribution of sporophytes
