Deep sea buoy hydraulic system

Abstract

The invention provides a deep sea buoy hydraulic system. The system comprises an inner oil bag, an oil outlet of the inner oil bag is connected with a bidirectional gear pump, the bidirectional gear pump is respectively connected with an oil tank and an oil inlet of an outer oil bag through a supercharging unit, an oil outlet of the outer oil bag is connected with the bidirectional gear pump to form a closed hydraulic oil path, the bidirectional gear pump is matched with the supercharging unit for using, so that the problem that self-suction capacity is insufficient due to a plunger pump is solved, the energy consumption is reduced by the low-pressure bidirectional gear pump and the supercharging unit, and the underwater working time is prolonged; a double-action booster pump is adopted, the interior of the double-action booster pump adopts a mechanical structure mode to achieve supercharging, and the floating and diving flexibility is high, the problem that the occupied space is too large and the load is too large due to the fact that an air pump and an auxiliary structure such as a driving air pump are installed is avoided.

Description

technical field [0001] The invention relates to the technical field of marine detection, in particular to a deep-sea buoy hydraulic system. Background technique [0002] Ocean profile buoys, also known as "Argo" buoys, are mainly used for profile parameter detection, data sampling and data transmission, and can independently complete floating and diving movements during the detection process. [0003] At present, most of my country's ocean profiling buoys are 2000-meter-level profiling buoys, and their research and development and production are in the mature stage. The research on 4000-meter-level and 6000-meter-level profiling buoys is still in the theoretical and experimental stage, especially for deep sea areas. Research on the hydraulic system of profile buoys is still in its infancy. The Teledyne Webb Company of the United States has developed a 4000-meter-level APEX profile buoy, and the Scripps Institute of Oceanography has successfully developed a 6000-meter-level D...
