Profile motion platform driven by ocean temperature difference and its power generation control method

Abstract

The invention relates to a profile motion platform driven based on ocean temperature difference energy and a power generation control method thereof, and belongs to the technical field of ocean equipment. The profile motion platform comprises a sealed cavity and a buoyancy control loop. The buoyancy control loop comprises a liquid storage pump, an energy storage device, an outer liquid storage device with discharge volume changing with storage quality of hydraulic oil, and an inner liquid storage device, wherein the liquid storage pump, the energy storage device, the outer liquid storage device and the inner liquid storage device are sequentially connected through oil lines to form a loop structure. A hydraulic motor for power generation, a first conduction control valve and a one-way valve only allowing the hydraulic oil to flow to the outer liquid storage device are sequentially connected to a pipeline located between the energy storage device and the outer liquid storage device in series. A short-circuit oil circuit is connected between a pipeline between the hydraulic motor and the first conduction control valve and the inner liquid storage device through a tee joint in a bypass mode; and a second conduction control valve is connected to the short-circuit oil circuit in series. Based on the added short-circuit oil circuit, the profile motion platform can generate power formultiple times in a profile cyclic motion process, so that the power generation efficiency is improved, and the profile motion platform can be widely applied to the field of ocean exploration.

Problems solved by technology

[0005] (1) Only one power generation can be performed in one profile cycle movement, resulting in low conversion efficiency of temperature difference energy

[0006] (2) Difficult to achieve fixed depth control

[0007] (3) It is impossible to rely on pressure to realize the movement of hydraulic oil from the outer oil bag to the inner oil bag and from the inner oil bag to the oil bag at the phase change, resulting in high complexity and high energy consumption of the entire hydraulic system

[0008] (4) Since the liquid storage capacity of the inner and outer oil pockets changes with the water depth, the control performance of the entire system is unstable

[0009] (5) The pipeline between the accumulator and the inner oil bag is prone to blockage, resulting in excessive pressure in this part of the oil circuit and damage to the components, and the problem that it cannot be floated and recovered smoothly

[0010] (6) It is impossible to rely on pressure to realize the movement of hydraulic oil from the outer oil bag to the inner oil bag and from the inner oil bag to the oil bag at the phase change, resulting in high complexity and high energy consumption of the entire hydraulic system
