Solar energy and temperature difference energy combined power generation system used for underwater vehicle

Abstract

The invention aims to provide a solar energy and temperature difference energy combined power generation system used for an underwater vehicle. The system comprises a photovoltaic module, a storage battery, an organic Rankine cycle power generation module and a phase change heat storage module, the organic Rankine cycle power generation module comprises a heat exchanger, a power turbine, a flash evaporator, a condenser and a liquid storage tank, and the phase change heat storage module comprises heat conduction silicone grease, a phase change heat storage material and a heat pipe. According to the system, photovoltaic power generation is carried out on the water surface to charge the storage battery, the phase change material stores waste heat of the solar photovoltaic module to carry out thermoelectric power generation underwater, a turbine power generation device stores electric power in the upward floating and downward diving processes of the underwater vehicle, water and underwater uninterrupted power generation is achieved, the technical problems that an existing underwater vehicle is single in energy source and low in energy conversion efficiency are solved, the problem that the endurance of the existing underwater vehicle cannot be guaranteed is solved, and therefore the technical problem that the endurance of the underwater vehicle is short is solved, and long endurance of the underwater vehicle is achieved.

Description

technical field [0001] The invention relates to a power generation system, in particular to an underwater vehicle power generation system. Background technique [0002] With the increasing demand for exploration of marine resources, underwater vehicles can conduct large-scale uninterrupted surveys of marine resources and underwater environment mapping, and have broad application prospects in marine resource surveys and other fields. In the face of diverse and long-term observation tasks, the power supply of underwater vehicles is the key to limiting their long-term endurance work. At present, underwater submersibles are powered by batteries. When the batteries need to be replaced or recharged, they need to surface and dock with the mother ship. Problems such as inconvenient battery disassembly, harsh offshore operating environment, and short battery life have seriously affected underwater vehicles. work performance. In order to solve the power problem of submersibles, most...
