The Buoyancy System and Design Method of Submarine buoy for Ocean Internal Wave Observation

Abstract

The invention discloses a buoyancy system for ocean internal wave observation subsurface buoy and a design method of the buoyancy system. The design method of the buoyancy system comprises the steps that large buoyancy control of a releasing unit is conducted, specifically, the net buoyancy of the releasing unit is 3 times the net weight of the releasing unit in water; allowance buoyancy control of an observation unit is conducted, specifically, the net buoyancy of the observation unit is 1.2 times the net weight of the observation unit in the water; zero-buoyancy control of a connecting system is conducted, specifically, soft connection of the connecting system adopts a zero-buoyancy connecting cable, and a zero-buoyancy control unit is additionally arranged at the hard connection position of the connecting system; the total buoyancy control of a main floating body is conducted, specifically, the net buoyancy of the main floating body is twice the net weight of a whole buoyancy system, except an anchoring system and the main floating body, in the water; and weight redundancy control of the anchoring system is conducted, specifically, a quantitative control base line of the weight of the anchoring system is at least 3 times the total weight of the entire buoyancy system, except the anchoring system, in air. The design procedure of the subsurface buoy buoyancy system is simplified, operation is convenient, the design defects are overcome, the subsurface buoy success rate is increased, and the guarantee is provided for the reliability and validity of ocean internal wave observation data.

Description

technical field [0001] The invention relates to the technical field of ocean internal wave observation, in particular to a buoyancy system of an ocean internal wave observation submersible buoy and a design method thereof. Background technique [0002] The submersible buoy is a traditional way of ocean internal wave observation, and the design of its buoyancy system is very important. First of all, it must ensure the stability of the position of the observation instrument when the internal wave passes by, and also requires smooth deployment and easy recovery. [0003] The design of the buoyancy system through buoyancy calculation is a basic step, but it must be based on a systematic grasp of the specific purpose of submersible buoy observation and the living environment, otherwise the calculation results may be misleading, and there have been many cases of relying on blind calculations On the contrary, only relying on the physical grasp of the rough frame without accurate ca...

[0003] The design of the buoyancy system through buoyancy calculation is a basic step, but it must be based on a systematic grasp of the specific purpose of submersible buoy observation and the living environment, otherwise the calculation results may be misleading, and there have been many cases of relying on blind calculations However, the accident caused by the loss of the submerged mark; on the contrary, only relying on the physical grasp of the rough frame without accurate calculation will lead to waste of cost and increase of useless work, and even affect the effect of observation
