Seawater collecting device and method

Abstract

The invention relates to a seawater collecting device. The device comprises a disc which is transversely arranged, a plurality of sampling cylinders, pulling wires and wire winding mechanisms; the sampling cylinders, the pulling wires and the wire winding mechanisms are arranged at intervals in the circumferential direction of the disc; a winding and unwinding rope is fixed on the disc; the sampling cylinders are longitudinally fixed on the disc, and sampling covers are hinged to the upper ends of the sampling cylinders; the wire winding mechanisms comprise wire winding shafts which are longitudinally arranged on the disc in a rotating mode, wire winding gears and wire winding frames; the wire winding gears and the wire winding frames are fixed on the wire winding shafts in a sleeving mode; one ends of the pulling wires are fixedly connected with the upper ends of the sampling covers, and the other ends of the pulling wires are wound on the wire winding frames; a driving motor is longitudinally fixed in the center of the disc; a driving wheel is fixedly connected to an output shaft of the driving motor in a sleeving mode; a section of rack is arranged on the outer edge of the driving wheel; and the rack can be meshed with the wire winding gears. The driving motor drives the rack to rotate for intermittently driving the wire winding shafts to rotate for winding the pulling wiresto realize intermittent opening of the sampling covers and seawater is collected.

Description

technical field [0001] The invention relates to the field of marine monitoring, in particular to a seawater collection device and a collection method thereof. Background technique [0002] The ocean contains the richest species diversity and the largest biomass on earth. Both developed and developing countries recognize that marine genetic resources have great potential application value. Marine environmental monitoring is an important part of marine strategy development, and the analysis of seawater composition is an important content of marine environmental monitoring. Since the composition of seawater at each depth is different, the collection of seawater at a specific depth is the first step in the analysis of seawater composition, and it is also a particularly important step, which directly affects the correctness and accuracy of subsequent analysis results. Existing seawater collection devices often open the lid first, and then close the lid of the water collection bo...

Problems solved by technology

However, in actual use, since the seawater collection device is equipped with a one-way valve at the bottom of the syringe to prevent seawater from other depths from being mixed in, it is difficult to push the piston rod to the bottom of the syringe before suctioning seawater, and it is difficult to fully discharge The air in the syringe is troublesome to use and poor in applicability
