Power supplying and driving device and method for ocean monitoring device

Abstract

The invention discloses a power supplying and driving device and method for an ocean monitoring device. By means of the power supplying and driving device and method for the ocean monitoring device, power can be supplied to the ocean monitoring device, meanwhile, driving force can be provided for the ocean monitoring device, and the ocean monitoring device is simple, convenient to use, high in reliability, low in cost, free of pollution and long in service life. The characteristic that a solid-liquid phase change material conducts phase changes along with temperature changes is utilized, a phase change cylinder containing the solid-liquid phase change material is in direct contact with seawater, the phase change cylinder can be solidified and melted repeatedly in the floating and submerging process of the ocean monitoring device, the ocean temperature difference energy is converted into the size change, energy is charged to an accumulator, the accumulator is controlled to release the energy and change the size of an external oil bag so as to drive the ocean monitoring device to vertically move through a series of pipelines and valves, a hydraulic motor is driven to rotate to drive a generator to generate electricity, and power is supplied to a control system and a measuring device of the ocean monitoring device.

Description

technical field [0001] The invention relates to the technical field of marine environment monitoring, in particular to a power supply and drive device for marine monitoring equipment and a method thereof. Background technique [0002] At present, various security threats from the sea are becoming more and more serious. On the South China Sea issue, my country's sovereignty is violated, islands and reefs are occupied, sea areas are divided, resources are plundered, development is blocked, and security is threatened. The crisis in the South China Sea is escalating step by step. In order to better detect and observe the marine environment and collect ocean-related data and information, various equipment and devices for marine environment monitoring have been successfully developed and put into use. [0003] For these monitoring equipment that needs to work continuously in the ocean for a long time, energy supply has become a problem. At present, domestic and foreign products a...

AI Technical Summary

Problems solved by technology

[0004] 1) The number of lithium batteries that the device can carry is limited, and the working life of the device is limited

At the same time, these batteries make the device heavy and bulky

[0005] 2) Due to the remote location and the unstable working location, the marine monitoring equipment is discarded after the battery is exhausted, and then the monitoring equipment needs to be re-launched, which costs a lot of money

Or it can be floated up regularly to replenish energy artificially, which greatly limits the depth and breadth of its work

[0006] 3) For discarded equipment, lithium batteries will pollute the marine environment

[0007] 4) The battery is prone to failure, making the device less than the design life
