An underwater glider temperature difference energy driving device

Abstract

The temperature difference energy driving device of the underwater glider proposed by the present invention, through the phase change working medium in the heat exchanger, reasonably utilizes the characteristics of the external water temperature changing with the depth during the working process of the glider, and collects the thermal energy in the environment to complete the conversion of mechanical energy ; Change the heavy buoyancy of the glider through water intake and drainage, provide the driving force for the underwater glider for a long-term endurance, and ensure the stability and hydrodynamic characteristics of the glider during navigation. The main shell is a rotary structure, the two ends are sealed by sealing flanges, the tail is equipped with a buoyancy adjustment mechanism, and the interior adopts a cylindrical layout. The heat exchanger adopts a heat transfer enhanced structure, and heat transfer copper sheets are installed inside to improve the heat transfer efficiency of the heat exchanger and the volume change rate of the phase change working medium, which can more efficiently utilize the ocean temperature difference energy. The driving device has good expansibility, and can be widely used in underwater temperature difference energy buoys and underwater temperature difference energy sinking and floating detection devices in addition to being applied to underwater gliders.

Description

technical field [0001] The invention relates to an ocean temperature difference energy buoyancy adjusting device, in particular to a driving device for adjusting the heavy buoyancy of an underwater glider. Background technique [0002] The underwater glider is a new type of underwater vehicle that combines buoy technology with underwater vehicle technology. Its biggest feature is its long endurance, and it is suitable for carrying specific sensors to conduct relatively comprehensive monitoring and measurement of water areas. It is different from traditional underwater vehicles in that the underwater glider has no propellers. It uses net buoyancy and attitude adjustment to obtain propulsion, and consumes very little energy, so it has the characteristics of high efficiency and strong endurance. [0003] The temperature difference energy underwater glider is a new type of underwater vehicle that uses renewable clean energy. It relies on absorbing the temperature difference betw...
