Integral sampling system

Abstract

The embodiment of the invention provides an integral sampling system, and aims to solve the technical defect that in the prior art, a cable needs to be released down underwater to take samples such as a water sample and a plankton sample or data such as hydrographic survey respectively. According to the technical scheme of the embodiment of the invention, the integral sampling system comprises a pullable cable, a plankton net, a water sampler and a hydrologic detector, wherein the plankton net comprises a netting; a net hole is formed in one end of the netting; a net bottom tube is arranged at the other opposite end; the net hole is connected with the cable through a biological net cable; the water sampler is arranged on the cable; the hydrologic detector is buckled on the net hole through a detector protection rope buckle.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of sampling, and in particular to an integrated sampling system. Background technique [0002] Plankton is a small aquatic organism suspended in the water body, mainly composed of phytoplankton and zooplankton, and has a food chain relationship with each other. It is an important part of the aquatic ecosystem and the main component of the productivity of the aquatic ecosystem. It plays an important role in the maintenance of system balance and the normal progress of ecological processes. [0003] The plankton net is a net for collecting plankton in aquatic ecosystems. It is used for the investigation of micro organisms in water areas. Due to different collection objects, it has various shapes and sizes. When in use, it needs to be connected to the collection net through a cable, so that the collection net reaches the required collection area (or depth) to ensure the normal progress...

AI Technical Summary

Problems solved by technology

[0004] Water samples, plankton samples, and hydrological measurements (mainly referring to temperature, salinity, pH, depth, turbidity, etc.) usually need to be collected separately, which takes a long time; existing collection equipment mostly combines water sample collection with hydrological measurements. There is no plankton collection equipment such as collecting zooplankton, and it is relatively cumbersome, and generally needs to be installed on special survey ships
