Laboratory internal wave and internal solitary wave making device

Abstract

The invention discloses a laboratory internal wave and internal solitary wave making device which includes a water tank, a bracket and a rack. Slide rails are respectively arranged on the upper ends of the left and right walls of the water tank. The two sides of the lower end of the bracket are in sliding connection with the slide rails through two movable sliders. The movable sliders are fixedly connected with bracket. A vertical connecting rod is arranged on the upper end of the bracket. Two fixed sliders are arranged along the axis of the vertical connecting rod. The gear is provided with a vertical slide rail matching the two fixed sliders on the side away from the rack sawteeth. The vertical slide rail and the rack are welded together. A servo motor for driving the vertical slide rail to move to or away from the water tank along the vertical direction is also arranged on the bracket. A pumping plate or a cylindrical thrust box is arranged at the lower end of the rack. The extending direction of the slide rails is perpendicular to the plane where the pumping plate is located. The axis of the cylindrical thrust box is perpendicular to the left and right walls of the water tank. The laboratory internal wave and internal solitary wave making device has a simple structure, is convenient to operate, and can be switched between internal wave making and internal solitary wave making through the pumping plate and the cylindrical thrust box.

Description

technical field [0001] The invention relates to a laboratory internal wave and internal solitary wave wave-making device, which belongs to the technical field of ships and ocean engineering. Background technique [0002] Ocean internal waves are different from sea surface fluctuations in that they cannot be easily detected by people. Because when the ocean internal wave passes near the sea surface, the vertical fluctuation of isodensity near the sea surface is very small, and its maximum amplitude appears in the interior of the ocean. However, the amplitude of internal ocean waves can reach hundreds of meters, causing large-scale movement of the thermocline or densocline inside the seawater, which in turn transmits matter and energy, changes the propagation route of acoustic signals in seawater, and leads to strong convergence of seawater. divergence, and pose a serious threat to marine structures, etc. Therefore, it is very important for the study of internal waves.
