Compact and modular ocean temperature difference energy driven buoyancy adjusting device

Abstract

The invention discloses a compact and modular ocean temperature difference energy driven buoyancy adjusting device. The compact and modular ocean temperature difference energy driven buoyancy adjusting device comprises a buoyancy adjusting hydraulic unit and an ocean temperature difference energy capture converter. The main structure of the buoyancy adjusting hydraulic unit is composed of an oil tank end cover, an oil tank pipe shell, a long cylinder pipe wall, a valve block end cover and a flow guide cover. An internal hydraulic system of the buoyancy adjusting hydraulic unit is composed of an inner leather bag, an outer leather bag, an energy accumulator, an electromagnetic valve, a one-way valve, a cabin penetrating cable, a valve block, a pressure sensor, hydraulic steel pipes and connectors, wherein the hydraulic steel pipes and the connectors are arranged between hydraulic devices. The ocean temperature difference energy driven buoyancy adjusting device serves as an independent modular unit and can be externally carried by an existing underwater vehicle platform, the ocean temperature difference energy driven buoyancy adjusting device captures ocean temperature difference energy and converts the ocean temperature difference energy into hydraulic energy in the submerging and floating process along with submerging and floating of an underwater vehicle, and meanwhile buoyancy adjusting energy is provided for the vehicle.

Description

technical field [0001] The invention belongs to the technical field of underwater unmanned vehicle engineering, and in particular relates to a compact and modular ocean temperature difference driven buoyancy adjustment device for carrying and using on small and medium-sized underwater vehicles. Background technique [0002] At present, underwater vehicles mainly rely on their own batteries and fuels to provide energy for the energy supply during navigation. Due to the limited battery and fuel energy carried, the endurance and self-sustainability of underwater vehicles are restricted. The development of ocean observation and detection in the direction of deep and open seas puts forward higher requirements for the endurance and self-sustainability of underwater vehicles. The aircraft cannot complete long-term missions in deep and open seas only by relying on the limited amount of batteries and fuel it carries. Utilizing the energy of the external marine environment on the spo...
