Description
Technical field
The invention belongs to electromechanical integration, be specifically related to a kind of instrument of measuring waters vertical section turbulent motion situation.
Technical background
In order to protect the marine environment, efficiently utilize ocean resources, consider the demand of warfare at sea simultaneously, marine survey technology is most important.The turbulent motion of seawater is ubiquitous a kind of complicated phenomenon in the ocean, and it is significant for the theoretical and meteorological variation of research ocean large scale deeply to be familiar with oceanic turbulence mechanism.Seawater movement is turbulent flow high frequency random motion form mostly.Research seawater turbulent motion rule has important scientific meaning to understanding oceanographic phenomena, wherein obtains the seawater of microscale and shears the important source book that flow speed data is research seawater turbulent motion rule and kinetic energy dissipation rate.It is that ocean measuring instrument by special use measures that the microscale flow velocity is sheared data.The turbulent flow section plotter can the Measuring Oceanic vertical section the microscale data, the turbulent flow research of ocean is had vital role.Canada has begun the research of vertical turbulence section plotter the seventies in 20th century, and Osborn in 1972 etc. develop " Osborn " section plotter, but there are a lot of problems in it, comprises portability, stability and vibrations or the like; Subsequently, people such as Osb0rn develop Camel series section plotter, this series section plotter carries two VELOCITY SHEAR sensors, a thermal sensor, a pressure transducer and a pair of acceleration transducer, its section movement velocity 0.7m/s uses disposable cable that the signal of measuring is transferred to the surveying vessel deck.Bendford institute of oceanography (BIO) has developed Octuprobe series and improved EPSONE section plotter, they carry the VELOCITY SHEAR sensor, fast temperature response sensor FP07, and pressure transducer and acceleration transducer, 500 meters of working depth are by the folding and unfolding of Kevlar cable with obtain data.All there are product in Washington, DC university, Oregon State University, WoodsHole institute of oceanography and Japan etc. in addition.But the structure of these turbulent flow section plotters is all very complicated, and is complicated unusually aspect processing, and has a common problem, and operation is very loaded down with trivial details when promptly measuring.
Summary of the invention
The objective of the invention is to propose the instrument of a kind of Measuring Oceanic microscale (millimeter level) turbulent motion situation, instrument is thrown in the water, measure the vertical section turbulent motion of aqua region, reclaim the back and read the data of measurement by computing machine by heaving pile.
The present invention is achieved by the following technical programs.With reference to accompanying drawing; flow profile measuring device has gland bonnet 1, pressure transducer 2, rechargeable battery 3, composite sealing pad 4, seal casinghousing 5, sealing bolt 6, O shape ring O-ring seal 7, shears probe 8, cable signal line 9, control circuit board 10, circuit board support 11, electric cable splice enclosure 12, cable splice 13, buoyant disk 14, probe protective cradle 15, fastening bolt 16 and heaving pile suspension ring 17 etc.Fixedly constitute annular seal space by gland bonnet 1 and seal casinghousing 5 by bolt and O shape ring O-ring seal 7-3.Shear probe 8 and be loaded on the annular seal space lower end, be connected with control circuit board 10, by composite sealing pad 4 sealings by cable signal line 9.Shearing probe 8 is the main sensors of flow profile measuring device, and the turbulent motion situation is converted into voltage signal.Pressure transducer 2 is housed in annular seal space.Rechargeable battery 3 and control circuit board 10 are fixing by the circuit board support in the chamber 11.Electric cable splice enclosure 12 is sealingly fastened in the annular seal space with cable splice 13 usefulness sealing bolts 6, and cable splice 13 places electric cable splice enclosure 12 inner free to rotate.Outer upper end at annular seal space is equipped with buoyant disk 14, and buoyant disk is the frustum shape, is fixed in the annular seal space outside with fastening bolt 16.Buoyant disk 14 is used for adjusting the net weight power of flow profile measuring device in water, and then regulates the decline rate of instrument.The lower end edge circumference of annular seal space is equipped with three probe protective cradles 15, prevents the accident collision injury.Heaving pile suspension ring 17 are used for the tether cable, guarantee that instrument uses the back to reclaim.
When starting working, at first unclamp sealing bolt 6 electric cable splice enclosure 12 is taken out annular seal space, take out cable splice 13 and charge, pass through computer starting control circuit board 10 after to be charged the finishing.Control circuit board 10 is used for the measuring process of control instrument and the storage of finishing measurement data.After heaving pile suspension ring 17 are fixed cable, with the instrument input under water, pressure transducer 2 opening entry submergence depths, when reaching trigger condition, control circuit board 10 begins to store the data of measurement.When reaching the fathoming of appointment, control circuit board 10 stops to gather, and reclaims by the cable that ties up on the heaving pile suspension ring 17.Can read the data of measurement by computing machine, finish one action.
Characteristics and beneficial effect that the present invention has are, can realize the measurement of waters turbulent motion situation easily, and its cable splice part-structure can substitute the watertight cable connector, can realize the sealing of deep water, has convenient and practical characteristics.
Description of drawings
Accompanying drawing assembles structural drawing for each parts of the present invention.
Embodiment
By the following examples and with reference to accompanying drawing structural principle of the present invention is described further.For present embodiment, 2000 meters of the flow profile measuring device design effort degree of depth are used aluminum alloy materials, and physical dimension is as follows: 780 millimeters of length overalls, 110 millimeters of seal 16 diameters, 140 millimeters of lower sealing cover 2 place's diameters.Shearing probe protective cradle 15 is three, and along circumferentially uniform, its uniform diameter is 129 millimeters.Buoyant disk 14 is the diagram taper, and density of material 0.54 can provide 3 kilograms of buoyancy.1 kilogram of the relative weight of flow profile measuring device in water, at the uniform velocity decline rate 0.7 meter per second.250 hertz of the sample frequency of shearing probe 8,2 hertz of the sample frequency of pressure transducer 2.Withstand voltage and hermetic unit by, pressure transducer 2, sealing bolt 6, seal casinghousing 5 and shear probe 8 and constitute jointly.Shear between probe 8 and the gland bonnet 1 and be tightly connected by O RunddichtringO 7-2.The checking sealing degree of depth can reach more than 2000 meters by experiment.Cable splice 13 adopts 7 core cable-to-cable connectors, and pressure transducer 2 ranges are 20 MPas, and control circuit board 10 uses 8,000,000 FLASH memory stores data.
