AI Technical Summary

Technical Problem

The traditional lake plankton sample collection device has low collection efficiency and cannot effectively collect phytoplankton. It will cause a large movement of water during mobile collection, causing plankton to leave its initial position, which makes the collection work cumbersome and time-consuming.

Method used

A lake plankton sample collection device is designed, including a mounting bracket, a telescopic device, a bearing frame, a bearing plate and a bidirectional telescopic device. The collection component consists of a mounting plate, a folding cylinder, a connecting plate and a guide member. Through the cooperation of the telescopic equipment and the bidirectional telescopic device, the mounting plate moves laterally in the lake, and the water flow enters the folding cylinder laterally, and opens the folding cylinder to achieve the collection of plankton.

Benefits of technology

It improves the collection efficiency and quality, reduces the impact of water flow movement on plankton, and ensures that phytoplankton is stable between the collection devices until the collection is completed. After collection, the water in the folding cylinder is quickly discharged through the gas supply and discharge assembly, leaving plankton behind for subsequent extraction.

Abstract

The present invention relates to a lake plankton sample collection device in the technical field of lake plankton sample collection, comprising: a mounting bracket, a telescopic device arranged on the top of the mounting bracket, a receiving frame arranged at the output end of the telescopic device, and a bearing plate connected to the bottom of the receiving frame, wherein a bidirectional telescopic device is arranged in the bearing plate, and both output ends of the bidirectional telescopic device are connected to a connecting frame, and a collecting component for collecting plankton is connected to the bottom of the connecting frame. The present invention is provided with a collecting component, because the folding cylinder is in a folded state, when the collecting device enters the lake, the impact on the water surface is small during the process of its entry, and the water flow will not be caused to move significantly, and the two groups of mounting plates are close to each other, so that the mounting plates move laterally in the lake, so that the water flow can enter the folding cylinder laterally from the water inlet, so that the water flow and plankton at the water inlet are "sucked" into the folding cylinder, thereby improving the collection efficiency and collection quality.
