Abstract

A low-noise hydrophone element suitable for a wave glider belongs to the technical field of underwater acoustic receiving transducers. The invention aims to solve the problems of many blind spots and inaccurate visual positioning in existing manual inspections of substations. The invention includes a curved disc hydrophone, a support ring, three suspension springs, an upper sound-transmitting flow-guiding positioning cover, a lower sound-transmitting flow-guiding positioning cover and a balance wing plate; In the circular hole on the wing plate, the curved disk hydrophone is a cylindrical structure, which is set in the center of the support ring. The end of the three suspension springs far from the hydrophone is installed on the support ring, and the end near the hydrophone is installed on the support ring. On the side of the curved disc hydrophone, the upper and lower sound-transmitting guide positioning covers have the same structure, and are symmetrically installed on the upper and lower sides of the circular hole of the balance wing plate, so that the curved disc hydrophone is placed in the cavity of the upper and lower sound-transmitting guide positioning cover , and the cavity has the amplitude space for the vibration of the curved disk hydrophone. The invention is applicable to wave glider.

Description

technical field [0001] The invention relates to a low-noise hydrophone element suitable for a wave glider, and belongs to the technical field of underwater sound receiving transducers. Background technique [0002] The wave glider is a new type of unmanned marine vehicle that has emerged in the past ten years. It can convert the endless wave energy in the ocean into its own forward thrust through the hang gliding board, so as to convert the wave energy into kinetic energy to make it move forward, and cooperate with the solar panels and batteries installed on the surface floating body boat without providing additional power. The wave glider is an autonomous ocean observation platform that can continuously observe the ocean environment under different sea conditions. It has outstanding advantages such as ultra-long endurance, autonomy, unmanned, zero emission, small size, and economy. [0003] The wave glider has various and flexible sensor loading capabilities. It can be u...
