Deep-sea automatic continuous sectional intelligent buoyage system

Abstract

The invention provides a deep-sea automatic continuous sectional intelligent buoyage system. The system includes a satellite communication system, a buoy protection cover, a glass floating ball compressive cabin, a high-pressure plunger pump, an internal oil bag, a one-way valve, a ball valve, an air pump, an electromagnetic air valve, a battery pack, a circuit control system, a temperature-salinity-depth sensor and a buoy bottom base; a piston in the internal oil bag divides the internal oil bag into an internal oil cavity and an internal air cavity; the high-pressure plunger pump pumps hydraulic oil in the internal oil bag into an external oil bag to make the total drainage volume of a buoy increased and the buoy floats up; when the electromagnetic air valve is switched on, an external air bag, the internal air cavity and the glass floating ball compressive cabin are communicated, and when the ball valve is switched on, the external oil bag is communicated with the internal oil bag;an internal-external pressure difference between vacuum in the glass floating ball compressive cabin and an external sea pressure presses the hydraulic oil in the external oil bag and air in the external air bag back to the glass floating ball compressive cabin, and the buoy dives down. According to the system, by changing the self-drainage volume of the buoy, the average density is changed, it isachieved that the buoy floats up and dives down at deep-sea 0-6000 m, the cost is low, the work is reliable, and the power dissipation is very low.

Description

Technical field [0001] The present disclosure relates to the field of marine monitoring, in particular to a deep-sea self-supporting profile intelligent buoy system. Background technique [0002] The deep-sea self-sustained profile intelligent buoy is also called Argo buoy. The main feature of the buoy is that it is convenient to carry. Once deployed, it will continue to operate automatically without human maintenance. It can drift freely in the ocean and automatically profile the temperature, salinity and depth of the ocean subsurface between the sea surface and 6000 meters. [0003] Among the deep-sea intelligent profile buoys currently in operation of the global Argo real-time ocean observation network, there are mainly two representative deep-sea buoys, the 6000-meter APEX buoy developed by the US Webb company and the deep-sea 4000-meter ARVOR buoy developed by the French Martec company. The number of smart buoys is the largest. The deep-sea 6000-meter APEX buoy of the Americ...

Problems solved by technology

However, this design method also has corresponding problems. On the one hand, the air lock problem caused by the insufficient oil absorption capacity of the high-pressure plunger pump affects the oil discharge capacity of the inner oil bag and the working efficiency of the system; on the other hand, the use of double springs and The mechanical method of combining the rolling diaphragm needs to be customized according to the oil discharge pressure, which increases the production cost of the buoy prototype, and the spring and the rolling diaphragm itself have a low service life due to the frequent oil discharge work of the buoy
