Bentonic organism collector

Abstract

The invention relates to a bentonic organism collector which comprises two grab buckets (10), a locking device and a closing device, wherein the grab buckets (10) are used for opening or closing an opening at the bottom of a box body (20); clamping pieces (30) are arranged on the grab buckets (10), fastening pieces (40) are arranged on the box body (20) and move upwards or downward relative to the box body (20), and the clamping pieces (30) and the fastening pieces (40) are clamped or separated to lock or unlock the opening states of the grab buckets (10) at both sides of the box body (20); and the end part of a steel wire rope (50) is fixed on one grab bucket (10), moves round the other grab bucket (10) and the box body (20) at the same side and arranged above the box body (20). The bentonic organism collector can pick up bentonic samples, not only can reliably sample, but also can exactly collect bentonic shellfish samples in set areas and depths, and is beneficial to protecting seafloor biotic environment.

Description

technical field [0001] The invention relates to a surface collector, in particular to a benthos collector. Background technique [0002] With the massive consumption of the earth's resources, the ocean has become a new field for human beings to further develop. Whether it is studying seabed ecology, investigating resources, or developing and utilizing marine ranches, it is inseparable from seabed sampling and investigation. Especially in the investigation of seabed shellfish resources, the method of trawling is usually adopted, and the special net gear is sunk into the seabed, dragged by a ship, so that the net gear moves close to the seabed, and the shellfish samples from the seabed are collected; The trawling method not only does great damage to the seabed environment, destroys the ecological balance of the seabed, but also cannot accurately collect a certain area of ​​seabed shellfish resources, so that there are uncertain errors in the statistical and calculation results...

Especially in the investigation of seabed shellfish resources, the method of trawling is usually adopted, and the special net gear is sunk into the seabed, dragged by a ship, so that the net gear moves close to the seabed, and the shellfish samples from the seabed are collected; The trawling method not only does great damage to the seabed environment, destroys the ecological balance of the seabed, but also cannot accurately collect a certain area of ​​seabed shellfish resources, so that there are uncertain errors in the statistical and calculation results; In the sampling process, there are also problems such as unreliable grasping and closing actions, and the inability to carry out sampling smoothly, which seriously restricts the sustainable development of breeding production.
