Bentonic organism collector

Abstract

The invention relates to a bentonic organism collector, which comprises a box body and two grab buckets. The grab buckets used for opening or closing an opening at the bottom of the box body are provided with clamping pieces, while the box body is provided with fastening pieces. The clamping pieces and the fastening pieces are clamped or separated to lock or unlock the opening states of the grab buckets at both sides of the box body. The end portion of a steel wire rope is fixed onto one grab bucket and moves round the other grab bucket and the box body at the same side and arranged above the box body. During the sinking and sampling process, the two grab buckets are locked at an opened state. Upon contacting the seabed, the clamping pieces and the fastening pieces are separated from each other and the opened locking state of the grab buckets are released. During the closing of the two grab buckets, samples at the seabed are picked up and put into the box body by the grab buckets. The bentonic organism collector not only can reliably sample, but also can exactly collect bentonic shellfish samples in set areas and depths, thus 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.
