Swing-hydrofoil-type wave energy collecting device for small-size ocean underwater vehicle

Abstract

The invention discloses a swing-hydrofoil-type wave energy collecting device for a small-size ocean underwater vehicle. The swing-hydrofoil-type wave energy collecting device comprises a swing hydrofoil, a transmission cabin, an internal rotary transmission mechanism, a cabin connecting baffle and an electric generator. The internal rotary transmission mechanism comprises an input shaft, a gear accelerating mechanism and an output shaft. The swing hydrofoil is connected with the input shaft through a U-shaped connecting piece, the output shaft is connected with the electric generator, the cabin connecting baffle achieves sealed connection between cabins, and bearing saddle holes used for supporting the input shaft or the output shaft are formed in the cabin connecting baffle; and a spring is further connected between the swing hydrofoil and a shell body of the transmission cabin. According to the swing-hydrofoil-type wave energy collecting device for the small-size ocean underwater vehicle, based on the difference of hydrodynamics responses of the two parts of the swing hydrofoil and an engine body of the underwater vehicle, the heaving and dipping energy of wave is absorbed by utilizing the swing hydrofoil, the input shaft is driven to conduct rotational motion, after acceleration is conducted, the electric generator is driven by the output shaft to generate electricity, and the problem of the energy supply of long-time operation of the small-size ocean underwater vehicle is solved; and the swing-hydrofoil-type wave energy collecting device further has the advantages that the structure is simple, disassembly and assembly and maintenance are convenient, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of marine vehicles, in particular to a swing-wing wave energy collection device for small marine vehicles. Background technique [0002] Small marine vehicles mainly include underwater autonomous underwater vehicle (AUV), remotely operated vehicle (ROV), underwater glider (Glider) and surface glider (ASV). As a convenient and efficient marine mobile platform, it has very important strategic significance in the fields of marine resource exploration, underwater military reconnaissance, and remote equipment monitoring. It is an important part of the integrated monitoring network of sea, land, air, and sky diving. [0003] At present, the power source of small marine vehicles mainly relies on primary batteries, storage batteries or fuel cells, etc., and the limited internal space also restricts the total amount of power that can be loaded, which can only provide power supply for several hours to several days of ...
