MEASURING SYSTEM FOR STUDY OF SMALL-SCALE TURBULENCE IN SURFACE SEA LAYER

摘要

The invention relates to oceanographic engineering, in particular to marine measuring systems. The measuring system for study of small-scale turbulence in the surface sea layer includes a stationary platform and instrument container with sensors connected to measuring apparatuses fixed at given horizon in the surface sea layer. The instrument container is installed with possibility of fixation at any given horizons in the surface sea layer. It is provided with means for control of its position and is fixed in vertical position in the cardan of power frame arranged as a ring placed in horizontal position, to that one, symmetrically in circle, three flexible links are connected, one of those is a cable-rope that is connected to the sensors and the mean for control of position of the instrument container, it goes through a block fixed at the end of the boom that is fixed with its other end on the lower deck of the platform with possibility of lift upwards in vertical plane with respect to the fixation point. Then the cable-rope goes through a block fixed on the lower deck of the platform by the line of the axis of the boom, and through a hoist with current collector it is connected to measuring instruments installed on the platform. Each of two other flexible links goes through one of the blocks fixed on the lower deck of the platform symmetrically with respect to the line of boom axis. Those two blocks with a block fixed on the end of the boom in layout are the tops of an equilateral triangle. Then each of two flexible links named is connected to one of the two other hoists installed on the platform. To the lower section of the instrument container on a cord with given length a streamlined load with given weight is fixed. The invention increases effectiveness and reliability of investigation of a given surface sea layer due to provision of stabilization of the sensors in space in given horizon, with possibility of following displacement of those and stable installation at any other given horizons, and due to decrease of labor consumption at production of the system and possibility of its operation without application of diving works.
