Abstract

The invention relates to a profile motion platform that can be driven based on ocean temperature difference and can be controlled by fixed depth, and belongs to the technical field of marine equipment. The platform includes a buoyancy control circuit, a hydraulic motor, a generator and a control unit; the buoyancy control circuit includes a liquid storage pump, an accumulator, an external liquid storage device and an internal liquid storage device which are sequentially connected to form a circuit structure through an oil circuit; The first conduction control valve, the hydraulic motor and the first one-way valve are serially connected in series between the energy device and the external liquid storage; the second conduction control valve is connected in series between the external liquid storage and the internal liquid storage; A short-circuit oil circuit connected to the internal liquid reservoir is connected between a conduction control valve and the hydraulic motor, and a second check valve is connected in series on the short-circuit oil circuit; the hydraulic motor constitutes a hydraulic pump based on the rotation of the generator, so as to communicate with the first A one-way valve, an external liquid reservoir, a second conduction control valve, an internal liquid reservoir and a second one-way valve are sequentially connected in series to form a fixed-depth control loop system. The platform integrates power generation and depth control functions, and can be widely used in 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. Background technique [0002] Ocean profile motion equipment is an important tool for people to study and explore the ocean. In order to prolong its service life, the motion equipment is usually configured to include a lithium battery for power supply and a power generation device based on ocean temperature difference energy. [0003] For example, the patent document with the publication number CN105889144A discloses a kind of ocean temperature difference energy power generation device, which is used to build an ocean profile motion platform; figure 1 As shown, the ocean temperature difference power generation device includes a sealed cavity and a buoyancy control circuit; wherein, along the direction of travel of the hydraulic oil, the buoyancy control ci...

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
