Description
Technical field
The utility model relates to a kind of ocean observation investigation and uses equipment, relates in particular to the subsurface buoy that a kind of ocean observation field is used.
Background technology
Marine Submersible Buoy System is one of visual plant of ocean environment observation.Different according to contact method between subsurface buoy and water surface support equipment (lash ship or platform), can roughly be divided into two large classes: a class is that cable underwater observations subsurface buoy is arranged, and provides power by lash ship to it by cable, and the people carries out remote control by cable to it on lash ship; Another kind of is without cable underwater observations subsurface buoy, also is the subsurface buoy of autonomous type observation under water.
Traditional cable formula ocean observation submerged buoy system that has generally is comprised of lower apron and machine waterborne.Lower apron generally is comprised of main buoyancy aid, detecting instrument, float anchor system and releaser.Common main buoyancy aid cloth is placed in sea lower about 100 meters or the darker zone; The anchor system is fixed on whole system on a certain selected measuring point.On the mooring rope between main buoyancy aid and the anchor, hang up as required multilayer automatic Observation instrument and float, in the junction of mooring guy and anchor releaser is installed.Marine Submersible Buoy System is laid by repair ship, and observation instrument carries out under water macrocyclic automatic Observation and observed data is stored.During recovery system, repair ship arrives former measuring point, and machine waterborne sends instruction makes releaser discharge anchor block, and system's floating reclaims.
Traditional cable that has lays formula ocean observation subsurface buoy for the ocean wave parameter on the aspect of observing different depth under the sea, must place required observation instrument at the different depth at be separated by tens meters or hundreds of rice along heaving pile, therefore, cause cost very high owing to the observation instrument quantity of carrying.Tradition has cable formula ocean observation subsurface buoy to be fit to long-term ocean wave parameter observation work, does not possess the characteristics of maneuverability.
Take the ARGO buoy as the example introduction without the principle of work of cable formula ocean observation subsurface buoy: the sink-float function of buoy mainly relies on fluid power system to realize.Hydraulic efficiency pressure system then is comprised of parts such as single cycle pump, leather bag, pressure sensor and pressure ducts, and leather bag is contained in the outside of buoy float, has pipeline to link to each other with hydraulic efficiency pressure system.The leather bag volume is increased, cause the buoyancy of buoy to increase gradually and rise.Otherwise plunger pump is drawn back the oil in the leather bag, the leather bag volume-diminished, and buoy buoyancy reduces thereupon, until gravity is greater than buoyancy, buoy float sinks gradually.If the program that input is write by the predetermined action requirement in the control microcomputer of buoy, then microcomputer can be controlled submerged depth according to the depth parameter that pressure sensor is measured, length of the halt, floating, sectional parameter measurement, the water surface stop and data transmission under water, and the working link such as dive again, thereby realize the functions such as automatic sink-float, measurement and data transmission of buoy.
The measurement process of ARGO buoy is to arrive set depth by program setting so that buoy is dived in advance, then utilizing self-contained various sensors to carry out serial section in uphill process measures, after buoy arrives the sea, automatically take off data is sent to satellite earth receiving station by location and data transmission satellite system, after signal conversion processes, sends to the buoy owner.Buoy approximately needs 6-12 hour at the length of the halt on sea, and after whole data transfers were complete, buoy can sink to desired depth again automatically, restarts next cyclic process.Although the ARGO buoy is unlike there being cable formula buoy need carry a lot of groups of sensors, but it can not move at any time as required, do not possess the function that stops at a certain set depth yet, the characteristics that do not possess maneuverability, and data can not real-time Transmission, need to be after emerging via satellite transfer transmission to the buoy owner.In addition.The maximum oil drain quantity of ARGO buoy is limited, and the size of oil drain quantity is determined by the oil drain quantity of a stroke of fluid power system piston, is subject to the restriction of cylinder diameter size, length.
The research of submarine hydrothermal solution starts from 1977, and at that time, the Alfven of the U.S. number manned submarine was adopted to get the sulfide that is comprised of iron pyrite, blende and chalcopyrite at the axial region of Eastern Pacific's mid-ocean ridge.1979 again in same place approximately on the seabed lava of 2610-1650 rice, found that dozens of is emitting the chimney of black and white smog, approximately 350 ℃ the ore deposit hydrothermal solution that contains sprays from the chimney of 15 centimetres of diameters, after sea water mixing on every side, produce very soon precipitation and become " black smoke chimney ", accretion mainly is comprised of pyrrhotine, iron pyrite, blende and copper iron sulfide.These Seafloor Sulfides are piled up and are formed upright column cima, are called " black smoke chimney ".The extensive development of cold seepage is in movable and seabed, passive continental margin slope, under the bottom deposit interface, take water, hydro-carbon (natural fuels and oil), hydrogen sulphide, fine-grained sediment as main component, the fluid that temperature and seawater are close, inject the basin to gush with the seepage mode, and producing a series of physics, chemistry and biological agent, this effect and product are called cold spring.The place that cold spring is different from hydrothermal vent is, the liquid that fountain ejects and sea temperature is unanimous on the whole on every side, and the liquid of submarine hydrothermal solution ejection is projecting sea temperature then.We also do not have the instrument and equipment that can directly observe the upwelling of submarine hydrothermal solution or cold spring at present.
