Ocean profile motion platform based on ocean temperature difference energy driving and capable of achieving depth setting control

Abstract

The invention relates to a profile motion platform given based on ocean temperature difference energy and capable of achieving depth setting control, and belongs to the technical field of ocean equipment. The platform comprises a buoyancy control loop, a hydraulic motor, a generator and a control unit. The buoyancy control loop comprises a liquid storage pump, an energy storage device, an outer liquid storage device and an inner liquid storage device, which are sequentially connected into a loop structure through oil lines. A first conduction control valve, a hydraulic motor and a first one-way valve are sequentially connected in series between the energy storage device and the outer liquid storage device; a second conduction control valve is connected in series between the outer liquid storage device and the inner liquid storage device; a short-circuit oil circuit communicated with the inner liquid storage device is connected between the first conduction control valve and the hydraulic motor in a bypass mode; and a second one-way valve is connected to the short-circuit oil circuit in series. The hydraulic motor forms a hydraulic pump based on the rotation of the generator, so thatthe hydraulic pump is sequentially connected with the first one-way valve, the outer liquid storage device, the second conduction control valve, the inner liquid storage device and the second one-wayvalve in series to form a set-depth regulation and control loop system. The platform integrates power generation and depth setting control functions and can be widely applied to the field of ocean exploration.

Description

technical field [0001] The invention relates to an ocean detection equipment, in particular to an ocean profile motion platform that can be driven based on ocean temperature difference and can be controlled by fixed depth.

AI Technical Summary

Problems solved by technology

[0005] (1) It is difficult to realize fixed depth control;

[0006] (2) For the working conditions in the deep water area, the accumulator is required to store high pressure to drive the whole process, resulting in a large overall volume and quality;

[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;

[0008] (4) The pipeline between the accumulator 16 and the inner oil bag 6 is equipped with equipment such as a power generation unit and a control valve, and the oil circuit is the longest, which is prone to clogging, resulting in excessive pressure and failure to float and recover;

[0009] (5) When the pressure of the accumulator is low, it is difficult to detect deep water areas
