Deep-sea hydrothermal-vent acoustic machine frame

Abstract

The invention relates to a deep-sea hydrothermal-vent acoustic machine frame. In the invention, the underwater acoustic transducer platform frame is a round frame, and slide blocks are uniformly distributed on the measuring circular-arc beam and can move along the measuring table circular-arc beam; an upper acoustic machine frame is a triangular frame, upper crossbeams are fixedly connected with each other through a four-way connecting piece, two of the upper crossbeams are fixedly provided with a right-angled hanger, and the other crossbeam is fixedly provided with an upper clamping device; a lower acoustic frame is a triangular frame, and lower crossbeams corresponding to the upper clamping device are fixedly provided with a lower clamping device; one end of a connecting rod is fixedly connected with the four-way connecting piece, and the other end is fixedly connected with a corresponding connecting piece; and one end of a brace bar is fixedly connected with the four-way connectingpiece, and the other end is fixedly connected with a three-way connecting piece. The invention takes the rigidity, strength and stability of the machine frame into account; and thus, on the premise of ensuring data measuring, the acoustic center range precision of the underwater acoustic transducer on the slide block can be controlled within the error range.

Description

technical field [0001] The invention belongs to the technical field of deep-sea equipment, and in particular relates to an acoustic frame for fixing an underwater acoustic transducer in an in-situ temperature measurement system of a deep-sea hydrothermal vent. Background technique [0002] Due to the existence of factors related to the origin of life such as huge heat flux, submarine hydrothermal organisms, and "dark biological chains", the submarine hydrothermal activity area has become a natural submarine laboratory. The temperature field is one of the key physical parameters for accurately and comprehensively estimating the hydrothermal heat flux and the way of hydrothermal movement and diffusion. It provides assistance in related fields such as the study of the growth model of the chimney body and the study of the mineralization mechanism of seabed hydrothermal fluids. In addition, for the extreme environment of high temperature, high pressure, corrosion, and dusty seab...
