Gravity type internal solitary wave maker with rotary blind door

Abstract

A gravity type internal solitary wave maker with a rotary blind door comprises a blind door and a linkage control mechanism, wherein the blind door comprises a plurality of long and thin stainless steel vanes; partition doors formed by all the vanes are arranged in an overlap mode; the overlap parts have good tightness when the partition doors are closed; the linkage control mechanism comprises link rod sliders, a slide guide, a cylinder and a steam pump; each stainless steel vane is riveted with upper and lower axes; all the upper axes are connected one ends of the link rod sliders corresponding to the upper axes; all the link rod sliders rotate around the corresponding upper axes on the vanes; the other ends of all the link rod sliders are connected with a cylinder piston rod; the link rod sliders reciprocate on the slide guide; a cylinder piston drives the link rod sliders to move to drive the upper axes on the vanes to simultaneously rotate 90 degrees while driving the piston rod to reciprocate, thus realizing synchronous opening and closing of the blind door. The movement amplitude of the mechanism generating the internal solitary waves through the interface density difference is greatly reduced, the quality of the made waves is effectively improved and the mechanical device has concise overall structure and is convenient to operate.

Description

technical field [0001] The present invention is an important experimental device for simulating ocean waves, especially a device for generating internal solitary waves in density-stratified water tanks, and is especially suitable for simulating large amplitudes in density-stratified oceans in large-scale tanks with lateral width and vertical depth Inner solitary wave. Background technique [0002] The vertical change of density is an important feature of the ocean, and the internal ocean wave is a kind of fluctuation that occurs in the seawater with stable density stratification, and its maximum amplitude occurs in the interior of the ocean. On the one hand, oceanic internal waves play an important dynamic role in the ocean and have an important impact on the improvement of marine primary productivity and the protection of the marine environment and ecology; on the other hand, oceanic internal waves, especially large-amplitude internal solitary waves, It affects the safe op...
