Long-term observation equipment and methods for submarine sand waves used in internal wave development areas

摘要

PROBLEM TO BE SOLVED: To provide a long-term observation device and an observation method for a seafloor sand wave used in an internal wave development area. A support mechanism is balanced and includes an anchor weight, a hexagonal rod, a ring measuring instrument control cabin and a support rod, the anchor weight is located at the bottom of the entire device, and the anchor weight is via a plurality of hexagonal rods. Connected to the ring-shaped measuring instrument control cabin above it, the internal wave energy power generation mechanism is installed inside the ring-shaped measuring instrument control cabin, and two support rods are symmetrically fixed to the outside of the ring-shaped measuring instrument control cabin, one of which is The support rod of the book is connected to the multifunctional observation rod via a mechanical pinch ring at its end, and the other support rod is connected to the sandy deposit sampling rod via the mechanical pinch ring at its end. Connected, the top of the ring-shaped measuring instrument control cabin is connected to the middle layer float on the seawater boundary layer surface via a Kevlar cable. [Selection diagram] Fig. 1
