Combined hoop

Abstract

The invention provides a combined hoop. The hoop comprises a locking component and a plurality of hoop frameworks, the locking component comprises a plurality of locking clamping parts, and a connecting part is arranged at one end of each locking clamping part; the other end of each locking clamping part is fixedly connected to one end of each hoop framework, so that a locking framework is formed, and a plurality of locking frameworks are detachably connected through the connecting part in sequence in a head-to-tail mode respectively, so that an annular hoop is formed. Due to the fact that each hoop framework of the combined hoop is detachable, when the hoop is free, particularly aiming at the hoop with larger diameter size, the hoop can be disassembled so that the occupying area and space can be reduced; what is more, when the hoop is used, all loop frameworks are rapidly locked through the locking clamping parts, so that an integral hoop is formed; therefore, the combined hoop can reduce occupying space and is convenient to carry, further locks each hoop framework rapidly, and is less in assembly time, simple and convenient.

Description

technical field [0001] The invention relates to a plankton collector, in particular to a combined net circle. Background technique [0002] Plankton are aquatic organisms that live in suspension in the water. They have no swimming ability at all, or their swimming ability is very weak, they cannot move for long distances, and they are not strong enough to resist the flow of water. Plankton includes two types of phytoplankton and zooplankton. Usually, plankton are small in size, but they are large in number and widely distributed, occupying an important position in the aquatic organisms world. Plankton is not only an important bait for fish, but its community structure and species composition are often used to evaluate the ecological environment of water bodies. [0003] At present, the tools used to collect plankton in shallow or deep waters are all simple integrated collectors, especially when using the net ring. When targeting shallow water, it is more convenient to carry...

AI Technical Summary

Problems solved by technology

[0003] At present, the tools used to collect plankton in shallow or deep waters are all simple integrated collectors, especially when using the net ring. When targeting shallow water, it is more convenient to carry the net ring. When it is necessary to collect deep water samples, The diameter of the mesh circle is relatively large, it takes up a lot of space, and it is very inconvenient to carry, and it also brings some troubles to the use of the collector. There are also some combined mesh circles that are very time-consuming to install, and at the same time During the assembly process of the combined net ring, parts are often lost, which often brings some inconvenience to the use of the collector.
