Buoyancy driving device of deep-sea underwater glider

Abstract

The invention discloses a buoyancy driving device of a deep-sea underwater glider, which comprises an oil tank, a high-pressure plunger pump, a gear pump and a normally closed electromagnetic valve. The oil tank is mounted in a pressure-resistant shell and consists of a shell fixedly connected with the pressure-resistant shell, a corrugated pipe type leather sac is mounted in the shell, one end of the corrugated tube type leather sac is hermetically fixedly connected with the bottom end of the shell, the other end of the corrugated tube type leather sac is hermetically fixedly connected with a movable end cover, the movable end cover is slidably connected into the shell, an end cover photoelectric sensor and a top end photoelectric sensor are mounted on the shell, an oil outlet of the oil tank is connected with an oil inlet of the gear pump, an oil outlet of the gear pump is connected with an oil inlet of the high-pressure plunger pump, an oil outlet of the high-pressure plunger pump is connected with an oil inlet of an outer oil sac, the oil outlet of the gear pump is connected with an oil inlet of the oil tank by a check valve communicated with the gear pump, and an oil outlet of the outer oil sac is connected with the oil inlet of the oil tank by the normally closed electromagnetic valve. By the aid of the buoyancy driving device, underwater gliders can run in the deep sea, and requirements on deep-sea operation for a long time and at high depth are met.

Description

technical field [0001] The invention relates to a driving device, in particular to a buoyancy driving device for a glider under deep sea water. Background technique [0002] At present, most of the underwater autonomous vehicles (AUVs) used for ocean parameter monitoring, marine biology and ecological observation, climate and meteorological services adopt the propeller propulsion method, which is severely constrained by energy sources and has a very short range, generally ranging from a few kilometers to hundreds of kilometers. , the maximum distance does not exceed 1000 kilometers, and the operation time is limited, usually a few hours to dozens of hours. As a new type of underwater equipment that emerged at the end of the 20th century, the underwater glider skillfully converts the gravity and buoyancy of objects into forward driving force, and can achieve long-term and large-depth operations with only a small amount of energy. Most of the buoyancy devices of gliders under...

AI Technical Summary

Problems solved by technology

Most of the buoyancy devices of gliders under shallow water use stepping motors to drive the pistons of hydraulic cylinders to reciprocate, so that the oil can be sucked out or discharged from the oil bag. Limited by the power of stepping motors and the sealing of hydraulic cylinders, the working depth generally does not exceed 200m, it is difficult to develop to the deep sea (over 1000m)
