Temperature difference energy power supply system of marine monitoring platform

Abstract

The invention provides a temperature difference energy power supply system of a marine monitoring platform, which comprises an integrated serial connected liquid metal magnetic fluid generator, a compression extrusion type temperature difference acquisition device, an energy storage and release device, a connecting device and an electrical storage device, wherein the integrated serial connected liquid metal magnetic fluid generator is vertically fixed inside the monitoring platform and connected with the energy storage and release device and the electrical storage device; and the compression extrusion type temperature difference energy acquisition device is vertically fixed inside the monitoring platform and exposed in seawater as well as connected with the energy storage and release device inside the monitoring platform through the connecting device. In the invention, by using temperature difference among different depths of cold and heat water layers in sea, hydraulic oil is pressurized by using an expansive force of a wax solid-liquid phase transition material is heated and melted, the serial connected liquid metal magnetic fluid generator is periodically driven for generating electricity and charges for the storage battery. The invention can be applied to an unmanned underwater propelled marine monitoring platform.

Description

technical field [0001] The invention relates to a power supply device for a marine monitoring platform, in particular to a power supply device for an unmanned underwater self-propelled marine monitoring platform. technical background [0002] Ocean monitoring technology is a strategic requirement for national defense construction and economic development, and it is also a necessary means for ocean development and utilization, environmental protection, and disaster prevention and mitigation. With the continuous advancement of science and technology, marine monitoring has entered a three-dimensional comprehensive monitoring stage integrating air, sea surface and underwater monitoring technologies. Aviation and satellite remote sensing technology can realize large-area, real-time or quasi-real-time synchronization from the air to the ocean surface, and fixed monitoring stations, survey ships, buoys, submersible buoys and bottom-mounted monitoring platforms can solve fixed-point...
