A multiplexing hydraulic oil circuit applied to underwater glider driven by ocean temperature difference

Abstract

The invention discloses a multiplexing hydraulic oil circuit applied to an underwater glider driven by ocean temperature difference, including a head fuel tank, a middle fuel tank, a tail fuel bag, an accumulator, a heat exchanger, an oil return solenoid valve, and an oil discharge solenoid valve. valve, the first one-way valve, the second one-way valve, the third one-way valve, air pump, gas solenoid valve, air pressure sensor, oil pressure sensor and connecting oil pipes to form the oil return circuit (lower head oil circuit) and the solidification oil circuit , release oil circuit (the first lift oil circuit), the second lift oil circuit, energy storage oil circuit five functional oil circuits. The invention utilizes the multiplexing of the hydraulic oil circuit, and utilizes the distribution position and volume of the circulating oil in each hydraulic component during the process of collecting, converting, and storing the temperature difference energy and adjusting the buoyancy state by using the hydraulic oil circuit to drive the underwater glider by the temperature difference. The temperature difference realized by the change can drive the change of the overall mass distribution of the underwater glider to adjust the axial position of the center of gravity and the gliding pitch angle. Compared with the axially moving battery pack adjustment method, the present invention has equal adjustment ability.

Description

A multiplexed hydraulic oil circuit applied to an underwater glider driven by ocean temperature difference energy technical field The invention belongs to the technical field of novel marine unmanned aircraft, be specifically related to a kind of water driven by ocean temperature difference energy The multiplexed hydraulic oil circuit for the glider to implement pitch attitude adjustment. Background technique [0002] The ocean temperature difference energy-driven underwater glider is a kind of heave motion in seawater that relies on the change of the buoyancy state. At the same time, the unmanned underwater vehicle that adjusts its own pitch and attitude angle and moves in a "zigzag" trajectory in the ocean has power consumption. It has the advantages of low power, strong self-sustainability, long endurance, and high cost-effectiveness ratio. Observation activities have broad application prospects in the field of ocean observation. Among them, the temperature differe...

Problems solved by technology

[0004] Due to the natural environment energy supply method, the capacity and weight of the battery packs configured by the ocean temperature difference can be significantly reduced, and the configuration of the battery pack can be eliminated under ideal conditions. The adjustment ability of the method of axially moving the battery pack cannot meet the ocean temperature difference. Requirements for moving distance of center of gravity position and pitch angle adjustment range of underwater glider

In addition, axially moving the battery pack (weight) will generate additional energy consumption. This method is not suitable for driving underwater gliders with strict ocean temperature differences that require low power consumption.
