Temperature-difference-energy-drive ocean profile moving and power generating system with speed regulating valve

The invention discloses a temperature-difference-energy-drive ocean profile moving and power generating system with a speed regulating valve. The temperature-difference-energy-drive ocean profile moving and power generating 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 provided with a sequence valve and a reversing valve, an inner oil bag connected with the outer oil bag through a first oil return way provided with a sequence valve and a reversing valve, and a power generation device. The phase change liquid oil bags are connected with the inner oil bag through a second oil return way provided with a one-way valve. The reversing valve on the first oil return way and the sequence valve on the oil inlet way are controlled by the outer oil bag. The sequence valve on the first oil return way is controlled by the energy accumulator. The reversing valve on the oil inlet way is controlled by the inner oil bag. The temperature-difference-energy-drive ocean profile moving and power generating system can float and sink by means of the temperature difference of seawater; and the system is exquisite in design, does not need to be controlled by any electromagnetic valves, does not consume electric energy and can generate power, external control is not needed, the service life of the system is prolonged, and the reliability of the system is improved.
