Embodiment 1

[0056] Such as Figure 1-6 As shown, an ocean profiling buoy comprising,

[0057] The housing, the housing is composed of an upper end cover 23, a cylinder body 24 and a lower end cover 25, and a sealing ring is arranged between the upper end cover 23, the lower end cover 25 and the cylinder body 24 to realize the purpose of sealing, and the housing is arranged as The three parts are easy to disassemble and easy to maintain. An outer oil bag 2 arranged outside the casing, specifically, the outer oil bag 2 is arranged on the outer wall of the upper part of the cylinder 24, and the outer oil bag 2 is arranged on the upper part of the cylinder 24 can overcome the problem of insufficient self-priming force of the plunger pump 7 . The outer oil bag 2 forms a ring around the periphery of the cylinder 24, and an inner oil bag 4 is arranged in the housing. Specifically, the inner oil bag 4 is arranged at the upper part of the cylinder 24, which can also compensate for the self-primi...

Embodiment 2

[0103] as attached Figure 5 As shown, this embodiment is a replacement for the linear displacement sensor 9 in Embodiment 1. Specifically, the linear displacement sensor 9 is replaced by a flow meter 14. The specific connection and oil circuit control are as follows:

[0104] The flowmeter 14 is installed between the outer oil bag 2 and the pressure transmitter 3 or in the pipeline between the inner oil bag 4 and the outer oil bag 2 .

[0105] When the profile buoy floats up, the solenoid valve B11 and solenoid valve C12 are closed (solenoid valve A10 and solenoid valve D13 are normally open), the motor 8 drives the plunger pump 7, and the oil in the inner oil bag 4 passes through the solenoid valve C12 and flows through the column in turn. The plug pump 7, solenoid valve B11, pressure transmitter 3 and flowmeter 14 enter the outer oil bag 2, the volume of the outer oil bag 2 increases, the buoyancy of the profile buoy increases, and the profile buoy rises.

[0106] When the...

Embodiment 3

[0110] as attached Figure 6 As shown, in this embodiment, the plunger pump 7 in the power unit in Embodiment 1 is replaced by a two-way gear pump 16, and a hydraulic booster 15 and a relief valve 17 are added to the hydraulic oil circuit. The road control is as follows:

[0111] The above-mentioned motor 8 is driven and connected with a bidirectional gear pump 16, and the two ends of the bidirectional gear pump 16 are respectively connected with a relief valve 17 and a check valve. The relief valve 17 can protect the hydraulic oil circuit from pressure in the hydraulic oil circuit. Too large to destroy the work of the entire power unit; the two ends of the two-way gear pump 16 are also connected with the inner oil bag 4 and the outer oil bag 2, and the hydraulic booster 15 is connected between the outer oil bag 2 and the two-way gear pump 16, and the two-way gear pump 16 and hydraulic booster 15 can solve the problem of insufficient self-priming force that plunger pump 7 exi...

Abstract

The invention provides a marine profile buoy and a control method thereof. The marine profile buoy comprises a shell, at least one external oil bag, at least one internal oil bag, a power unit, a volume measurement unit and a control unit, wherein the external oil bags are arranged outside the shell, the internal oil bags are arranged in the shell, and the internal oil bags are communicated with the external oil bags; the power unit is in driving connection with the internal oil bags, and the power unit is used for driving the internal oil bags to make oil move between the internal oil bags and the external oil bags; the volume measurement unit is used for measuring the volume of oil in the internal oil bags, volume of oil in the external oil bags and/or the volume of oil between the external oil bags and the internal oil bags; the control unit is connected with the power unit, and the control unit receives the data measured by the volume measurement unit and controls the power unit todrive the internal oil bags. The buoy has the advantages of an adaptive control profile buoy, and moreover, the buoy can measure marine spring layer information and ocean current flow velocity and can obtain more marine information.

Description

technical field [0001] The invention relates to the technical field of ocean parameter monitoring, in particular to an ocean profile buoy and a control method thereof. Background technique [0002] Ocean profile buoys, also known as Argo buoys, can automatically move up and down in the vertical direction of the ocean according to mission requirements, rely on the sensors set in the profile buoys to measure the parameters of the ocean profile buoys, and transmit the measured data to Scientific research ships or shore-based receiving stations provide data for climate warnings, scientific research, and future development of the ocean. Specifically, the upward and downward movement of the profile buoy in the ocean mainly depends on the hydraulic system to control the volume of the oil bag. Under the condition that the mass of the profile buoy remains the same, increasing the volume of the oil bag can obtain greater buoyancy. When the buoyancy force on the profile buoy is greate...
