Drainage type buoyancy regulating device

Abstract

The invention provides a drainage type buoyancy regulating device. The buoyancy regulating device comprises a motor bracket, a motor, a band-type brake machine, a coupling, a ball screw, a ball screw pair, end covers, a sliding screw, ripple sacs, bearings, press covers, fastening nuts, small sealing rings, a connector, large sealing rings and sealing pressure strips. According to the drainage type buoyancy regulating device provided by the invention, seawater in the ripper sacs can be easy to drain, and the drainage volume change of an underwater glider is realized, so that the buoyance is regulated. The drainage type buoyancy regulating device has the advantages of being simple in structure, easy to operate, small in occupied space, good in reliability and the like.

Description

Technical field: [0001] The invention belongs to the field of marine environment monitoring and resource development, and in particular relates to a drainage type buoyancy regulating device. Background technique: [0002] Now marine environmental monitoring and marine development are getting more and more attention from various countries. Many new marine detectors have been designed, such as underwater autonomous vehicles, manned submersibles, underwater glider, etc. Among them, underwater glider is due to its navigation When using its own buoyancy to sail, it has the advantages of long sailing time and long sailing distance, so it is highly valued. In the design of an underwater glider, the buoyancy adjustment device is a very critical part, which requires the buoyancy adjustment to be very effective and reliable, and the structure should be as simple as possible, and the space occupied should be small; Most of the buoyancy adjustment devices are oil bladder type. Although...

Problems solved by technology

In the design of the underwater glider, the buoyancy adjustment device is a very critical part, which requires the buoyancy adjustment to be very effective and reliable, and the structure should be as simple as possible, and the space occupied should be small; and most of the current underwater glider Most of the buoyancy adjustment devices are oil bladder type. Although this design is effective, the overall structure is too complicated and the weight is relatively large. Therefore, a new type of buoyancy adjustment device is very meaningful and necessary
