Glass plate sampler for collecting micro-surface water samples and sampling method thereof

Abstract

The invention discloses a glass plate sampler for collecting micro-surface water samples, and the sampler comprises a glass plate and a fixed sampling bracket, wherein the fixed sampling bracket comprises an outer frame bracket, a first glass scraper, a first plastic plate, a middle partition, a water sample collecting bottle, a fixed partition, a second glass scraper and a second plastic plate; the first plastic plate and the second plastic plate are respectively disposed on both sides of the outer frame bracket, the first glass scraper is disposed on the vertical edge of the first plastic plate, the second glass scraper is disposed on the vertical edge of the second plastic plate, a gap is formed between the two glass scrapers; the middle partition is provided with a circular hole, whichis aligned with the first glass scraper and the second glass scraper; the fixed partition is disposed at the lower part of the outer frame bracket, the bottom of the water sample collecting bottle isplaced on the fixed partition, and the bottle mouth of the water sample collecting bottle is aligned with the circular hole. The device has the advantages of simple structure, low cost, small volume,light weight, convenient carrying and single operation, and is suitable for the research of micro-surface environmental and ecological aspects such as oceans, lakes and estuaries.

Description

technical field [0001] The invention relates to the technical field of micro-surface water sample collection equipment, in particular to a glass plate sampler for collecting micro-surface water samples and a sampling method thereof. Background technique [0002] The micro-surface sampler is a scientific research instrument used in the research of the micro-surface environment, ecology and biology of seawater or fresh water. The currently designed glass flat sampler generally requires two people to operate, one person holds the sampling bottle and funnel, and one person Use a glass scraper to scrape the water sample attached to the glass plate into the sampling bottle. If it is operated by a single person, the sampling bottle is not easy to fix due to the shaking of the boat, and the operation is inconvenient, time-consuming and laborious. However, the thickness of the micro-surface collected by another screen-type micro-surface sampler is uneven, and it is easily diluted by ...

[0002] The micro-surface sampler is a scientific research instrument used in the research of the micro-surface environment, ecology and biology of seawater or fresh water. The currently designed glass flat sampler generally requires two people to operate, one person holds the sampling bottle and funnel, and one person Use a glass scraper to scrape the water sample attached to the glass plate into the sampling bottle. If a single person operates, the sampling bottle is not easy to fix due to the shaking of the boat, and the operation is inconvenient and time-consuming.

The thickness of the micro-surface collected by another screen-type micro-surface sampler is uneven, and it is easily diluted by the lower water, and the micro-surface water is adsorbed on the screen and is not easy to recover.

Masaya Shinki once disclosed an electric roller type marine micro-surface sampling device, which is bulky and uses a rather complicated electronic and mechanical structure, which is expensive and difficult to maintain
