Sampling device and method for regularly collecting precipitates in lakes

Abstract

The invention belongs to the technical field of environmental sciences, and discloses a sampling device and method for regularly collecting precipitates in lakes. The method comprises the following steps: connecting a precipitate collecting bucket between floating balls and a cement block, laying the precipitate collecting bucket in water to collect precipitates, disconnecting the precipitate collecting bucket which collects the precipitates with the cement block, recycling the precipitate collecting bucket through the floating balls. The sampling device for realizing the method comprises two floating balls, wherein the floating balls are connected with a thin stainless steel bar through a first connecting rod; the thin stainless steel bar is connected with the precipitate collecting bucket through a second connecting rod; the precipitate collecting bucket is connected with a remote control relay breaker controlled by a remote controller through a third connecting rod; the relay breaker is connected with the cement block through a fourth connecting rod; the cement block is in contact with a muddy bottom. The method for regularly collecting precipitates in lakes, based on the device, and not only is simple and easy, but also has high accuracy and success rate.

Description

technical field [0001] The present invention relates to a sampling method, specifically a method for regularly collecting lake sediment, including the step of collecting sediment underwater; the present invention also relates to a sampling device, specifically a sampling device for regularly collecting lake sediment, comprising A device for collecting sediment at the bottom of the water belongs to the field of environmental science and technology. Background technique [0002] With the rapid development of my country's economy in recent years, human beings discharge more and more pollutants into lakes and other water environments, and lake pollution incidents occur frequently. The environmental safety of lakes has become the focus of social attention. Under the influence of various solid particles and animal and plant residues that naturally settle from the water body to the bottom of the water, lake sediment is an important part of the material cycle of the water body. It in...

Problems solved by technology

However, so far, there is still a lack of relatively mature sampling devices and methods in this respect. Chinese patent CN 102928527 A discloses a natural water suspended matter classification collection device and its collection method, but it needs to collect the water containing sediment from the lake water body. Collected on the ground for sampling, not directly in lake water bodies for continuous sampling

Therefore, there is no sampling device and method capable of regularly collecting lake sediments at present.
