Sampling apparatus for shallow water surroundings and biological sample collection

Abstract

The invention relates to sampling equipment for experimental research of environmental science or environmental engineering or aquatic organism, in particular to a sampling device for biological sample collecting in a shallower water area environment. The sampling device comprises a pole bracket 19, a fixed bracket 10, a sampling device 2, fans 3, ropes 8 and a plug pin 7, wherein two sides of the pole bracket 19 are provided with floaters 5, and the fixed bracket 10 with the sampling device 2 is fixedly connected above the pole bracket 19; the fans 3 driving the floaters 5 to move are arranged on the floaters 5 and are electrically connected with a storage battery 9 on the floaters by the plug pin 7; one side of the pole bracket 19 is fixedly connected with a fixing rod 11, two ropes 8 are respectively connected with the sampling device 2 and the plug pin 7. The invention has wide application range, easy component constitute and convenient operation, and can be applied to sample collecting of settlings, water samples, water body biological samples, and the like in shallower water areas such as rivers, beaches, ponds, and the like. The invention does not need large power facilities and complex daily maintenance, thereby having convenient and quick operation and stronger application function.

Description

technical field [0001] The invention relates to sampling equipment for environmental science or environmental engineering and aquatic biological experimental research, in particular to a sampling device for collecting shallow water environment and biological samples. Background technique [0002] In recent years, due to the increasingly severe environmental problems caused by water pollution and widespread concern from all walks of life, the research and treatment of polluted water bodies have also received great attention from relevant departments. However, judging from the current relevant research results, most of the research on polluted water bodies is often limited to deep water areas of larger water bodies or areas that can be directly touched by people on the shore (due to the existence of edge effects, shore samples often Distortion of the monitoring results), while just ignoring shallow water areas that are more relevant to people’s lives and have more complex wat...

However, judging from the current relevant research results, most of the research on polluted water bodies is often limited to deep water areas of larger water bodies or areas that can be directly touched by people on the shore (due to the existence of edge effects, shore samples often Distortion of the monitoring results), while just ignoring shallow water areas that are more relevant to people’s lives and have more complex water pollution characteristics. To some extent, it restricts scientifically and effectively carrying out the treatment or restoration of polluted water bodies

Undoubtedly, the root cause of this dilemma is that the ships used in the sampling process in the past could not reach relatively shallow waters (especially rivers, lakes or near-shore shallow seas and shoals with a water depth of less than 1 meter) or because The silt in the shallower waters is deep or there are other risks that make it impossible for the staff to reach. During the experiment, there is a lack of necessary sample collection equipment, and environmental samples in the shallower waters cannot be obtained, so it is impossible to obtain relevant parameters or reliable data
