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 pressure-resistant and sealed 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. 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 the pressure-resistant shell. In this embodiment, the temperature difference driven vertical lift underwater robot is designed to work in a water depth of 100 meters, with a water surface temperature of 20°C and a water depth of 100 meters with a temperature of about 10°C. The work...

Abstract

The underwater robot that can be driven vertically by temperature difference mainly has outer skin protection shell, outer skin, inner skin solenoid valve, sealed cylindrical shell, one-way valve and accumulator, etc. The outer body of the robot is composed of a sealed chassis, a thermal engine working chamber, a sealed cylindrical shell and a front sealing sphere, and the thermal engine working chamber is designed as a cylindrical sealed body with an interlayer. The working chamber is respectively connected to two forward and reverse conducting check valves through pipe joints. Each of the one-way valves has one way connected to the outer skin bag through the solenoid valve. The feature of the present invention is that it uses the temperature difference in the depth of the water area as the driving energy, changes the buoyancy of the system through the change of the volume of the external skin of the system, and realizes the tasks such as underwater observation and detection of the underwater robot in the designated water area through the control system. Equipped with different sensors, it can also realize the monitoring of water areas.

Description

technical field [0001] The invention belongs to electromechanical integration, and in particular relates to an underwater robot that can be driven vertically up and down depending on temperature difference. technical background [0002] In order to protect the marine environment and efficiently utilize marine resources, marine exploration is essential. It is far from enough to rely solely on manpower for the detection of the ocean, and it largely relies on marine detection tools. In recent years, due to the need for the development of marine resources and the urgent need for monitoring the marine environment, many developed countries in the world have continuously strengthened or updated the marine environment monitoring systems in the sea areas under their jurisdiction and the survey and monitoring methods for the marine environment and resources in the world's common sea areas. On a large scale, all platform systems that can monitor the underwater environment and extract ...
