Embodiment Construction

[0008] The structural principle of the present invention will be further described below through embodiments and with reference to the accompanying drawings. The outer integral pressure-resistant part of the underwater robot is composed of the outer skin protection shell 1, the sealing chassis 3, the heat engine working chamber 8, and the sealing cylindrical shell 18, and the O-ring sealing rings are used to seal the parts. The installation method of the horizontal glider 16 is as follows: insert the horizontal glider into the U-shaped groove at the joint of the thermal engine working chamber 8 and the sealed cylindrical shell 18, and fix it by pins (as shown in the cross-sectional view A-A of the accompanying drawings). For this embodiment, the accumulator 21 adopts a diaphragm accumulator with a working volume of 2L and a working pressure of 10Mpa. The working pressure of two solenoid valves and two one-way valves is 1.5Mpa. The heat engine working chamber 8 of the underwat...

Abstract

The gliding underwater robot driven by temperature difference mainly has outer skin bag, control circuit board, heat engine working chamber, inner skin bag, solenoid valve, one-way valve, accumulator, etc. The whole exterior of the underwater robot is composed of a sealed chassis, a thermal engine working chamber, a sealed cylindrical shell and a front sealing sphere. The thermal engine working chamber is designed as a cylindrical sealed body with an interlayer, and a control circuit board is arranged in the working chamber. The invention is equipped with replaceable horizontal wings, the robot can glide according to the predetermined course, and at the same time, the temperature change of the seawater is used to make the paraffin working medium produce a phase change as the driving energy, and the dive and buoyancy of the robot are controlled by the change of the skin bag volume . Underwater positioning is realized by using hydrodynamic force and GPS positioning, and the underwater robot completes tasks such as underwater observation and detection in designated water areas through the control system. The invention is equipped with different sensors and can also monitor water areas.

Description

technical field [0001] The invention belongs to mechatronics, 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 the ocean and other water environments, so they are also called underwater monitoring platforms. By carrying different measurement sensors, the underwater robot can be used for different purposes. The driving energy used by the general underwater robot is electric energy, which is provided by the lithium battery or other alkaline battery carried by itself. For example, the self-sustained Lagrangian detector ALACE developed by the United States and the electric-driven Slocum underwater glider produced by Webb research are all driven by electric energy. Their main disadvantage is that due to energy constraints, the operation time is limited, and it is difficult to operate in specific sea areas for a long time. This thermoele...
