Multi-degree-of-freedom deep sea vehicle with sandwich type structure based on piezoelectric driving

Abstract

The invention provides a multi-degree-of-freedom deep sea vehicle with a sandwich type structure based on piezoelectric driving, and belongs to the field of underwater vehicles. The problems that an existing underwater vehicle is large in structural size, high in manufacturing cost and the like when used in deep sea are solved. The device comprises a buoyancy regulation and control module, a middle rotation driving module and a bottom snorkeling driving module, a shell of the buoyancy regulation and control module is streamlined, an inner cavity of the buoyancy regulation and control module is of a hollow structure and is used for containing buoyancy materials, and the middle rotation driving module comprises two side spraying driving units which are distributed in the vertical direction; the two side spraying driving units are each internally provided with a piezoelectric vibrator and a side spraying water spraying opening, the bottom snorkeling driving module comprises a snorkeling driving unit used for achieving snorkeling movement, and the snorkeling driving unit is internally provided with a piezoelectric vibrator and a bottom direct spraying water spraying opening. The buoyancy regulation and control module, the middle rotation driving module and the bottom snorkeling driving module are sequentially, vertically and coaxially connected in a fastened mode to form a sandwich type structure. The multi-degree-of-freedom deep sea vehicle is mainly used for underwater vehicles.

Description

technical field [0001] The invention belongs to the field of underwater vehicles, in particular to a piezoelectric-driven deep-sea vehicle with a sandwich structure and multiple degrees of freedom. Background technique [0002] With the development of the marine economy, the increase in military demand and the urgent need for offshore oil and gas development, the theoretical and applied research on underwater vehicles has developed rapidly, and the number and types of vehicles have also increased significantly, including manned diving. vehicles, autonomous underwater vehicles, and cable-operated remote-controlled vehicles. [0003] Although the aircraft technology is relatively mature in theoretical research and practical application, there are still some shortcomings such as large structure size, high noise, poor environmental disturbance and high cost. When the existing common aircraft conducts deep sea exploration, in order to resist the deep water pressure, it is often ...

AI Technical Summary

Problems solved by technology

New functional materials, such as soft robots made of shape memory alloys and dielectric elastomers, although the structure can be miniaturized, but the movement form is relatively simple, it cannot achieve multiple degrees of freedom, and the cost is high
