Buoyancy regulating system and method of full-ocean-depth underwater glider

Abstract

The invention belongs to the technical field of hydraulics, and specifically discloses a buoyancy regulating system and method of a full-ocean-depth underwater glider. The buoyancy regulating system comprises an internal oil tank, an external oil bag, an oil-filling oil passage and an oil-draining oil passage, wherein the oil-filling oil passage and the oil-draining oil passage are arranged between the internal oil tank and the external oil bag; the oil-filling oil passage comprises a first hydraulic pump, a one-way valve, a three-position four-way electromagnetic directional control valve anda hydraulic pressure booster which are sequentially connected through an oil passage pipeline; the oil-draining oil passage comprises a second on-off valve and a second hydraulic pump connected through the oil passage pipeline; the second on-off valve is connected to the hydraulic pressure booster; and the second hydraulic pump is connected to the internal oil tank and used for draining the oil from the external oil bag into the internal oil tank through the hydraulic pressure booster, the second on-off valve and the second hydraulic pump in sequence. The buoyancy regulating system and methodof the full-ocean-depth underwater glider solve the problem that an existing buoyancy regulating device can not work under the condition of full sea depth, that the weight, size and power consumptionare relatively large, and that the working range is relatively small. The buoyancy regulating system and method of the full-ocean-depth underwater glider achieve the purpose of greatly increasing theoutput hydraulic oil pressure under the condition of slightly increasing the size.

Description

technical field [0001] The invention belongs to the field of hydraulic technology, and more specifically relates to a buoyancy adjustment system and method for a full-sea deep underwater glider. Background technique [0002] Underwater glider is a new type of underwater autonomous observation equipment, which has the characteristics of low noise, low power consumption, long voyage, long range, and high concealment. transport. my country's glider technology research has just started, vigorously developing deep-sea glider technology will effectively shorten the gap with foreign advanced levels, fill the domestic gap, break the foreign technology blockade, and have great significance for improving my country's deep-sea marine environment monitoring capabilities. [0003] The buoyancy control device is one of the core components of an underwater glider. However, most of the buoyancy control devices at home and abroad currently have a small working range and cannot cover the ent...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above defects or improvement needs of the prior art, the present invention provides a buoyancy adjustment system and method for a full-sea deep underwater glider, which uses a high-pressure hydraulic pump and a hydraulic booster in the buoyancy adjustment system to solve the existing problems. The buoyancy adjustment device cannot work under the condition of full sea depth (underwater 0-11000m), the mass, volume and power consumption are too large, and the technical problems of low working range have achieved a large increase in output with a small increase in volume The pressure of the hydraulic oil enables it to cover the full sea depth pressure range of 0-110MPa
