Description
Technical field
The invention belongs to marine monitoring technology fields, more particularly, to the water sail of sea drifting buoy.
Background technique
Satellite Tracking sea table drifting buoy is the instrument and equipment generally used in international ocean investigation, is typical
Lagrangian Current Observations, are substantially carried out the observation of sea surface stream, the hysteresis quality problem of flow measurement be it is most outstanding, from
One drifting buoy is laid so far, could not obtain satisfactory solution always.Be but with any it is generally acknowledged, that is exactly water sail
It plays a significantly greater role to the induction result for improving ocean current.
Water sail also known as ocean current plate are the important components of drifting buoy, main to provide the power of system drifting, measured layer water flow
It acts on water sail and generates drag, the buoy float of the water surface is driven to drift about, then pass through the localized delivery mould of buoy float enclosed inside
Block sends location data.
Past water sail generallys use umbrella-type ocean current plate, and it is due to using why umbrella-type ocean current plate, which is widely adopted,
Umbrella cloth that is at low cost, light-weight and being of close texture, for before laying packaging and transport both provide good condition, also as only
The on line length of umbrella plate and standard type control appropriateness is wanted, standard type can not be influenced in vertical direction to the induction of wave.It
The disadvantage is that laying difficulty, umbrella cloth is in softened state always and is difficult to accomplish.Even since laying, the on line of umbrella cloth begins some
It twists together, never opened eventually.However, umbrella ocean current plate or someone are with it lays depth usually in 30m
It is more than the depth of water.
Now widely used is column type water sail, and laying stretching, extension compared with compared with umbrella-type water sail has biggish improvement, but surveys
The hysteresis quality of stream is but still very significant.This kind of drifting buoy incomplete statistics that the whole world is being observed at present just has more than 4000
It is a, but the observation effect of these buoys, there is apparent lag, many experiments show when flow velocity is 1 throttling left and right, lag
Up to 10% or so；When flow velocity is 2 throttling left and right, lag up to 15% or so；When flow velocity is 3 throttling left and right, lag up to 25%
Left and right.This lag has seriously affected observation accuracy, and is difficult to effectively calibrate.Thus, it is necessary to take invention to arrange it
It applies, effectively reduces lag.
A large number of experiments show that influence drifting buoy drift about lag principal element first is that the buoyancy control of drifting buoy water sail
System, observation effect is not achieved less than predetermined water layer in the sinking that kicks the beam, overweight, is easy to alienation when being pulled by water and exhibits hysteresis, most
It is good be it is completely the same with the water density of observing water layer, still, it is not uniform for observing the vertical change of water layer, and in the mistake of float
Certain variation is had in journey, it is desirable that it is difficult that the water density of drifting buoy water sail and observation water layer, which reaches really completely the same,
, having reached consistent it is difficult to that water sail is made effectively to trail naturally.So carrying out buoyancy control to drifting buoy water sail
Key be：On the basis of keeping the control of entire water sail neutral buoyancy, weight is provided according to the variation range of observation water layer density
Measure the range of redundancy.It not only ensure that the expansion of entire water sail in this way, but also inhibited due to caused by water sail weight to greatest extent
It drifts about and lags.These, in previous document, patent of invention and product description is medium did not all occur.
A large number of experiments show that influence drifting buoy drift about lag principal element second is that drifting buoy water sail without slippage
Control.It is tested by a large amount of field observation, being drifted about in nature without the best example of effect is slipped is exactly jellyfish, imitates jellyfish
The manufacture of water sail is important inspiration of the invention.However, completely imitative jellyfish water sail is more troublesome in operational use, and cost
High, volume change control difficulty.So we mutually tie the cylinder-shaped sail body of easy to operate with anti-slip jellyfish shape villus
It closes, jellyfish shape villus is not only set on cylinder-shaped sail body, but also adds jellyfish shape suede on the supportive sail bone inside sail body
Hair lacing film, so that the drift for effectively reducing water sail slips.It is this that the drift slippage of water sail is reduced by jellyfish shape villus and lacing film
Measure, in previous document, patent of invention and product description is medium did not all occur.As for water sail merogenesis with it is right
Diameter hole is to increase slippage due to preventing and shrinking in the middle part of sail body because pulling, it is necessary to caused by increasing midfoot support, merogenesis number
The thickness for then depending on observation water layer, is not one layer constant.
Summary of the invention
The purpose of the present invention is being directed to the above-mentioned problems in the prior art, provides one kind and be obviously improved drifting buoy
The water sail of flow measurement hysteresis quality defect.
The basic element of character such as drifting buoy water sail, including sail face, sail muscle, sail bone and traction rope, water sail material are selected low respectively
In or close to density of sea water material, it is ensured that entire sail body weight is not more than corresponding buoyancy.
Further, since observation water body is all that lower water is higher than upper layer water density under normal circumstances, to keep water sail smooth
Excessive redundancy weight is stretched down and does not generate, the link for designing and producing adjustable weight carries out neutral buoyancy adjusting, keeps water
Redundancy weight is 5% or so of weight in water sail air in sail water.
Further, the cylinder-shaped sail body of easy to operate and anti-slip jellyfish shape villus are combined, not only in cylinder
Jellyfish shape villus is set on shape sail body, and adds jellyfish shape villus lacing film on the supportive sail bone inside sail body.
Further, to increase slippage due to preventing and shrinking in the middle part of sail body because pulling, increase midfoot support, thus by water sail main body
