Description

{Fouling organism sampler in underwater}

TECHNICAL FIELD The present invention relates to a sampler for sampling artificial fishes, natural rocks, coastal structures, intertidal rocks, and various marine adherent organisms adhering to the surface, and more particularly, The present invention relates to an underwater attachment biological sampler for preventing a collected specimen from being floated and lost by buoyancy in the case of a light object.

The underwater attachment biological sampler (10) is a device for collecting marine adherent creatures for quantitative and qualitative analysis. The underwater attachment biological sampler (10) It is a sampler for collecting small benthic organisms of 1mm or more in size, which have been scraped off using a fossil or chisel, such as coastal structures and rock gaps, by using the principle of aspiration. In addition to scuba diving, there is also a small, lightweight, rust-resistant material that can be collected in the intertidal zone.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a configuration of a general attached biological sampler.

As shown in FIG. 1, the conventional attachment biological sampler 10 has a blade 11 for easily detaching marine attachment organisms adhering to a structure in water, and the attachment biological sampler 10 (12) for collecting marine adherent creatures in a captured state. With this handle, efficient movement and collection are possible by yourself. In addition, the collected specimens are configured to prevent loss and loss of collected adherent organisms during activity by the lid breaker 13 designed to be closed by a spring device.

At this time, the main body is formed with a plurality of holes so that the water exits to the outside and only the attached biological sample is collected. The diameter of the holes formed is 1 mm in size, but not limited thereto, Depending on size and type, the size of the hole should also be determined.

However, when the marine adherent organisms are collected through the adhered bio-sampler 10, as the collection of adherent organisms is carried out in water, the small and light underwater attachment organisms collected are scattered in water by buoyancy, There are many microorganisms adhering to the inside of the microorganism, which are suspended and liquefied to the outside, resulting in poor reliability of quantitative and qualitative analysis data.

Accordingly, the collecting person guides the attached organisms suspended by the hand to the inside of the attached bio-sampler 10 or inserts the attached bio-organisms into the attached bio-sampler 10 while directly moving the attached biological sampler 10 back and forth It is necessary to perform troublesome operations such as carrying out a series of operations to insert it into the body 10, which is inconvenient.
