Embodiment Construction

[0008] The structural principles of the present invention will be further described below through embodiments and with reference to the accompanying drawings. The overall pressure-resistant part of the underwater robot is composed of an outer skin bag protection shell 1, a sealed chassis 3, a heat engine working chamber 8, and a sealed cylindrical shell 18, and the parts are sealed by O-ring seals. The installation method of the horizontal glider 16 is: the horizontal glider is inserted in the U-shaped groove at the junction of the heat engine working chamber 8 and the sealed cylindrical shell 18, and fixed by pins (as shown in the A-A sectional view of the accompanying drawing). For this embodiment, the accumulator 21 is a diaphragm accumulator with a working volume of 2L and a working pressure of 10Mpa. The working pressure of solenoid valve 14 and check valve 19 is 1.5Mpa. The thermal engine working chamber 8 of the underwater robot mainly plays a sealing role as a part of...

Abstract

A gliding underwater robot driven by temp difference energy is composed of external leather bag and internal leather bag for floating up or sinking down, control circuit board, working chamber of heat machine, electromagnetic valve, check valve, energy accumulator, the external casing consisting of sealed bottom, sealed cylinder and sealed front spherical end, exchangeable horizontal wings, and GPS. The temp variation of seawater can make paraffin wax generate phase change to provide drive energy.

Description

technical field [0001] The invention belongs to electromechanical integration, and in particular relates to a gliding underwater robot driven by temperature difference energy. technical background [0002] Underwater robots can be used as monitoring platforms to monitor oceans and other water environment, so they are also called underwater monitoring platforms. By carrying different measurement sensors, the underwater robot can be used for different purposes. Generally, the driving energy used by underwater robots is electric energy, which is provided by lithium batteries or other alkaline batteries carried by itself. For example, the self-sustaining Lagrangian detector ALACE developed by the United States and the electric energy-driven Slocum underwater glider produced by Webb research company are all driven by electric energy. Their main disadvantage is that due to energy constraints, the operating time is limited, and it is difficult ...
