An unmanned submersible system using ocean temperature difference to generate power and snorkeling and gliding control

Abstract

The invention discloses a snorkeling gliding control type unmanned submersible system using ocean temperature difference energy for generating power. Multifunctional airfoils are symmetrically mounted on the two sides of a submersible shell. Phase change working media and transmission liquid are stored in the multifunctional airfoils. Working media capable of achieving solid-liquid phase change in the ocean temperature gradient and deep sea differential pressure variation range are adopted as the phase change working media. Transmission of the transmission liquid in the multifunctional airfoils is controlled through volume changes in the phase change process. External linings are mounted at the roots of the multifunctional airfoils. Transmission liquid is stored in the external linings. Working gas and transmission liquid are stored in an energy storage cavity. Three-way valves control the inflow and outflow directions of the transmission liquid flowing into or out of the external linings. One-way valves control inflow and outflow of the transmission liquid passing through an internal lining, the multifunctional airfoils and the energy storage cavity. A safety valve controls the transmission liquid in the multifunctional airfoils to flow into a power generator when the transmission liquid reaches the preset outlet pressure. A check valve controls the inlet pressure of the power generator. The power generator is connected to the upper portion of a storage battery, and measurement control equipment and detection equipment are connected to the lower portion of the storage battery.

Problems solved by technology

[0005] However, the above ideas and concepts only consider the single use of ocean temperature difference energy, or simply provide buoyancy to realize the snorkeling and gliding control of unmanned submersibles; or simply realize power generation to solve the energy supply of unmanned submersibles

For the simple use of ocean temperature difference to provide buoyancy, it can only solve the power propulsion problem of unmanned submersibles, and about 40% of additional electric energy is needed to supply the payload; for the pure use of ocean temperature difference to generate electricity, the generated electric energy still needs to meet unlimited The propulsion power consumption of the snorkeling of the human submersible, whether it can realize the goal of propulsion of the unmanned submersible without energy in the true sense still needs further research
