Temperature difference energy driven ocean section movement system

Abstract

The invention discloses a temperature difference energy driven ocean section movement system. The system comprises phase change cavities, phase change hydraulic oil bags arranged in the phase change cavities, an energy accumulator connected with the phase change hydraulic oil bags through an oil outlet way, an outer oil bag connected with the energy accumulator through an oil inlet way, and an inner oil bag connected with the outer oil bag through a first oil return way. The phase change hydraulic oil bags are connected with the inner oil bag through a second oil return way. The outer oil bag and the phase change cavities are arranged outside a sealing cavity, and other parts and the oil ways are all arranged in the sealing cavity. According to the system, no electromagnetic valve is needed for control, and electric energy is saved; the system can automatically float and sink through temperature difference of seawater; phase change time can be changed in a self-adapting mode according to the temperature of seawater, and the system floats or sinks after completion of phase change, so that the number of section movement is greatly increased. Control of the system is achieved through oil pressure of hydraulic pipelines directly, a traditional pressure sensor is not adopted, cost is reduced, and the reliability of the system is improved.

Description

technical field [0001] The invention relates to an ocean profile motion system, in particular to an energy-saving temperature difference energy driven ocean profile motion system. Background technique [0002] Ocean profiling equipment is an important tool for people to study and explore the ocean. For monitoring equipment that needs to work continuously in the ocean for a long time, lithium batteries are traditionally used as power supply. However, a considerable part of the energy consumption of lithium batteries is used for driving and controlling the equipment, which greatly reduces the power consumption of profile movement equipment. service life. At present, there are motion systems driven by temperature difference energy, and the control of equipment motion is completed by solenoid valves. However, the energy consumption of tens of watts of solenoid valves is still too large for this kind of profile motion equipment that is on duty in the ocean for a long time. On t...

For monitoring equipment that needs to work continuously in the ocean for a long time, lithium batteries are traditionally used as power supply. However, a considerable part of the energy consumption of lithium batteries is used for driving and controlling the equipment, which greatly reduces the power consumption of profile movement equipment. service life

At present, there are motion systems driven by temperature difference energy, and the control of equipment motion is completed by solenoid valves. However, the energy consumption of tens of watts of solenoid valves is still too large for this kind of profile motion equipment that is on duty in the ocean for a long time.

On the other hand, sufficient ocean observation data is a necessary condition for people to have a deep understanding of the ocean. Traditional profile monitoring equipment is limited by battery power and cannot increase the number of profile movements.

Finally, the movement of profile monitoring equipment is generally controlled electrically by a single-chip microcomputer. Once a problem occurs, it will cause equipment failure and reduce the reliability of the equipment.
