Modular fixed-point profile buoy

Abstract

The invention relates to the field of marine environment monitoring, and in particular to a modular fixed-point profile buoy that comprises sensor modules which are sequentially connected and mutuallyindependent inside, a buoyancy material module, an electric control module, a buoyancy driving module and a power supply module; an emergency load rejection module is arranged on one side of the power supply module; an anchoring module is arranged at the lower end of the power supply module; a buoyancy adjusting mechanism is arranged in the buoyancy driving module; the buoyancy adjusting mechanism comprises a buoyancy adjusting clear water cabin and a buoyancy adjusting seawater cabin which are separated through an isolating membrane; clear water and a piston capable of moving in a reciprocating mode are arranged in the buoyancy adjusting clear water cabin; a through hole is formed in the buoyancy adjusting seawater cabin, and in addition, a plurality of hollow holes are formed in the lower end of a shell of the buoyancy driving module. The modular fixed-point profile buoy comprises a plurality of independent module units, different operation requirements can be met, the buoyancy adjusting structure is simple, the buoy cost is greatly reduced, and in addition, the anchoring module with a force unloading ring is further arranged, so that long-term fixed-point monitoring is achieved.

Description

technical field [0001] The invention relates to the field of marine environment monitoring, in particular to a modular fixed-point profile buoy. Background technique [0002] The ocean is the largest treasure house of resources on the earth. At present, marine technology has become an important field for the development of modern science and technology. Sensor detection technology for physical parameters of the marine environment is a key technology for detecting seawater temperature, salinity, depth, and turbidity. The submersible buoy system is a comprehensive equipment platform that applies marine sensor detection technology, and it is also an indispensable part of the all-weather three-dimensional observation system for the marine environment. my country has a continental coastline of about 18,000 kilometers.

Problems solved by technology

my country has a continental coastline of about 18,000 kilometers. However, the equipment capable of monitoring the marine environment in shallow waters within the coastline is still quite scarce, especially the lack of profiling buoy equipment that can achieve long-term, shallow waters, and fixed-point monitoring. The sea area can only be monitored by traditional monitoring methods, which not only consumes a lot of manpower and material resources, but also cannot accurately, long-term, and continuously collect statistics on the state of the marine environment in shallow sea areas

[0003] In addition, the shells of profile buoys widely used in the world are all designed in an integrated manner. After the design of the buoy is completed, its structural functions and application scenarios are determined and solidified, which limits the diversity of buoy functions to a large extent, and once the buoy If a fault occurs, it is very inconvenient to maintain and re-upgrade, and most of the buoyancy adjustment methods use external oil bladders to change their own drainage volume to realize the floating and diving of the buoy. This method requires very high processing technology of the oil bladders, so that the buoy The cost is expensive, and the profiling buoys in the prior art all drift with the waves and currents by themselves, and cannot perform long-term operations on a specific ocean area
