Description
Technical field
The utility model relates to the marine survey device, particularly relates to the float gear that carries out ocean drift loop detection.
Background technology
International ARGO global ocean observational network is the large ocean surveillance program of a coastal countries support and participation, big midocean lays an ARGO satellite tracking buoy every 3 warps, latitudes in the whole world, form a huge ARGO global view survey grid of forming by 3300 buoys, carry out the simultaneous observation of global ocean environment.The purpose of ARGO global ocean observational network is the sea temperature salinity section data of collecting global ocean time top layer fast, accurately, on a large scale, to improve the precision of climatic prediction, the threat of effectively defending the serious day by day climate damage in the whole world to cause to the mankind.
ARGO satellite tracking buoy is a self-sustaining drift loop detection buoy, claim neutral section to survey drifting buoy again, be implemented in big marine dive and come-up by changing own vol, in uphill process, finish the ocean profile survey, realize the cross-sectional data of quick, accurate Measuring Oceanic subsurface sea water temperature and salinity.
After self-sustaining drift loop detection buoy lays the sea, automatically dive beneath the water 2000 meters with interior equidensity layer depth, keep neutral free-floating with ocean current, arriving desired depth floats automatically, sensor measurement sea temperature and salinity in floating-upward process, be in floating condition again after arriving the sea, then on the sea via satellite system send the take off data of gathering to user.After finishing the take off data transmission, self-sustaining drift loop detection buoy sinks automatically again and begins next automatic circulation detection process: reach the predetermined degree of depth, automatically float and measure, arrive the sea and enter floating condition, send the take off data of gathering then.A self-sustaining drift loop detection buoy is surveyed at the marine ground automatic circulation that sinks repeatedly, floats, but continuous working is more than 2 years.
Fig. 1 shows the basic structure of existing self-sustaining drift loop detection buoy.As shown in Figure 1, self-sustaining drift loop detection buoy is a cylindrical-shaped structure, and cylindrical pressure shell 8 upper outside can make pressure shell 8 be in erectility in seawater around gimbal 4 is set.Include reducing motor 6, hydraulic planger pump 7, battery pack 9, control circuit board 5, satellite transmitter in the pressure shell 8, pressure shell upper end cover outer setting CTD sensor 2, pressure sensor 3 and communication antenna 1, pressure shell 8 bottom end cover outer setting are contained outermost layer of skin capsule 10.
In the floating-upward process of sounding buoy, CTD survey sensor 2 is constantly measured temperature, salinity and the depth datas of seawater, arrive behind the sea by satellite transmitter via satellite communication antenna 1 take off data is sent.
The come-up of sounding buoy, dive, reducing motor 6 drive hydraulic planger pump 7 actions, and the data collection of sensor and the satellite communication of take off data emission all are by control circuit board 5 controls.Control circuit board 5 is connected with reducing motor 6, communication emitter, CTD sensor 2, pressure sensor 3.The desired depth that the sounding buoy dive arrives is controlled according to the hydraulic pressure that pressure sensor 3 is measured.
Self-sustaining drift loop detection buoy marinely float repeatedly, dive and automatic circulation survey, and obtains the ocean temperature salinity data of different sections.The global ocean observational network that is made of a plurality of sounding buoys plays a significant role for collecting global ocean temperature salinity section data fast, on a large scale.
But self-sustaining drift loop detection buoy is only applicable to 2000 meters with dark marine site, ocean, because sounding buoy sinks need not to worry to touch at the end at big midocean.If use in the shallow sea, because sounding buoy can't be determined seabed depth, might touch at the end at any time in the then sinking process, the adsorption affinity in seabed can make sounding buoy rise once more, and therefore, above-mentioned self-sustaining drift loop detection buoy can not be used for the shallow sea.
The shallow sea is the important area of ocean exploitation and research, is in great majority again and closes on the state sovereignty scope, and therefore, the shallow sea Marine environmental data information is particularly important.How to utilize self-sustaining drift loop detection buoy and secret communication system to collect the shallow sea oceanographic data on a large scale and become the importance that the thalassographer pays close attention to and studies.
Summary of the invention
Self-sustaining drift loop detection buoy at prior art can not be used for the shallow sea, the utility model is released a kind of section sounding buoy that is applicable to the shallow sea, its objective is in the buoy float lower end sonar is set, automatically survey the seabed, determine buoy stereomutation trend and service direction up and down according to self and seabed distance, prevent that buoy from touching the end and adsorbed by the seabed and lose, be implemented in that float in the shallow sea and the automatic circulation that sinks is surveyed, collect the shallow sea Marine environmental data information on a large scale.
The related shallow sea self-sustaining drift loop detection buoy of the utility model is cylindric sealing pressure-resistance structure, and shell is made of cylinder pressure shell, upper end cover and bottom end cover.
CTD survey sensor and pressure sensor are equipped with in the upper end cover outside, and the communication antenna that transmits also is installed.The bottom end cover outside is equipped with and is contained outermost layer of skin capsule and sonar.
Hydraulic planger pump, reducing motor, air pump, communication emitter, control circuit board and metering circuit plate etc. are set in the pressure shell.The metering circuit plate places the top in the housing, is connected with control circuit board with sensor respectively.Control circuit board also connects sonar, hydraulic planger pump and air pump, and air pump communicates by the annular air-pocket of gas piping with the setting of cylindrical shell upper outside.
Hydraulic planger pump is communicated with Sheng outermost layer of skin capsule by high pressure fuel pipe.Hydraulic planger pump is driven by reducing motor, hydraulic oil is injected in leather bag or extracts out, to change the overall volume of buoy, realizes the come-up or the dive of buoy.In the floating-upward process of sounding buoy, the CTD survey sensor is constantly measured temperature, salinity and the depth data of seawater.
The dive of self-sustaining drift loop detection buoy in shallow sea in water and come-up motion, data acquisition, communication emission etc. are all controlled according to predefined program by control circuit board.
In sounding buoy sinking process, sonar constantly sends and receives sound wave, calculate the distance of buoy apart from the seabed, control circuit board is determined the rotating and the rotating speed of motor according to range data, after buoy and seabed distance was less than predetermined value, hydraulic planger pump began oiling in leather bag, and buoyancy strengthens; the buoy rate of sinking reduces, and began come-up during near the seabed up to buoy.
After the sounding buoy come-up arrives the sea, the control circuit booster air pump, air is pressed into ring-shaped gasbag, and ring-type leather bag bulging increases buoy buoyancy, and it is partly higher that buoy float is surfaced.Treat the complete water outlet of communication antenna, the communication emitter sends to satellite to the cross-sectional data of underwater survey, and land ground station receives the data that satellite is passed back, after the processing quasi real time send the user to.
The sonar that the related shallow sea self-sustaining drift loop detection buoy of the utility model utilizes the buoy float lower end to be provided with, measure the distance in sounding buoy and seabed, control dive campaign, contact the seabed when preventing the buoy dive and adsorbed by the seabed and lose, realize utilizing self-sustaining drift loop detection buoy to collect shallow sea marine environment section data fast, on a large scale.
