Description
Technical field
The utility model relates to a kind of offshore shoal water zone sounding gear, particularly relates to a kind of swath bathymeter system transducer shock preventing device.
Background technology
For offshore shallow water area, in various field operating type, column suspension type ship side is adopted to install close to hull centre of gravity place the simplest with flexibly beyond doubt, especially at fishing net, the shallow water area of the more water environment complexity of structures on waste water, also can pack up underwater unit rapidly when running into emergency situations.
Although suspension type does restriction to a certain degree to system water lower unit, due to column and non-rigid bodies, still can there is the teeter of certain amplitude in system water lower unit.Fluid stream closely vertically place steel pipe time pressure raise, water particle is impelled to form boundary-layer gradually in steel pipe leading edge and develop to both sides, when fluid viscosity lower (high reynolds number), boundary-layer departs near the widest part of tube wall cross section, wake flow forms a regular scroll stream at steel pipe lee side, occurs the vortex street (Vortexstreet) periodically provided.The interaction between moving of this swirl flow and steel pipe, just create vortex-induced vibration phenomenon, when the frequency of exciting force, during natural frequency close to the steel pipe of pads sounding system underwater unit of the frequency of namely vortex shedding, steel pipe resonates, even if now very little external force, the high vibration of steel pipe also can be caused.
The transverse vibration of column can make the system water lower unit of its lower end also swing thereupon, this swing produces tripartite's face to the quality of data and rings: first, for transmitting transducer, during high-frequency small amplitude motion, the relative position of sound source and reflection spot changes, produce a large amount of noise signal, and increase along with emission angle and increase; Secondly, for receiving transducer, a kind of noise is not only in vibration, also can have a strong impact on the precision of phase-shift detection; Again, by substantial deviation initial makeup location during transducer generation low frequency large-amplitude vibration, installation calibrating parameter in late time data processing procedure is caused to use.Due to vibration from limit effect, this phenomenon be discontinuity appearance.
Utility model content
Technical problem to be solved in the utility model is to provide one and greatly reduces vortex-induced vibration, avoids underwater unit to swing the swath bathymeter system transducer shock preventing device affecting measurement effect.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of swath bathymeter system transducer shock preventing device, comprise and be arranged on column on ship side by side hanging and be fixed on the drawstring of column lower end, the two ends of described drawstring are fastened and are gone up on the quarter, the outer wall of described column arranges guiding device, described guiding device is dismountable to be installed on the outer wall of column, described guiding device is the flow guide bar of flexible fin-shaped, described flow guide bar has a fin being arranged on the installation portion on column and being connected on installation portion, and described flow guide bar is looped around on column in the shape of a spiral.
As preferred technical scheme, the installation end of described flow guide bar installation portion is provided with groove, groove internal fixtion magnetic block, and described column is hollow tubular, is provided with the second magnetic block in column inner chamber, with groove corresponding position.
As preferred technical scheme, described second magnetic block is entrenched in the second groove be arranged on column madial wall.
As preferred technical scheme, described flow guide bar arranges connecting hole, separately have connecting pipe one end to be fixedly attached on the lateral wall of column through connecting hole.
As preferred technical scheme, the section of described flow guide bar is T-shaped.
As preferred technical scheme, the section of described flow guide bar is U-shaped.
As preferred technical scheme, the section of described flow guide bar is V-arrangement, and the lateral wall of described column is provided with bar-shaped trough, the end face of described flow guide bar extends flange, described flange snaps fitted in bar-shaped trough, separately has the bolt be arranged in outside bar-shaped trough to be screwed to bar-shaped trough, is fastened on flange side.
As preferred technical scheme, the section of described flow guide bar is S shape.
Owing to have employed technique scheme, a kind of swath bathymeter system transducer shock preventing device described in the utility model carries out water conservancy diversion by the flow guide bar be arranged on outside column, greatly reduce vortex street, make column not by the effect of vortex-induced vibration power, change vortex street form or eliminate vortex street and reach the effect weakening or eliminate vortex-induced vibration, this flow guide bar can cut randomly according to on-the-spot needs the such as column external diameter, underwater penetration, installs, easy to adjust, can not have an impact to transducer and peripherals.Meanwhile, the flow guide bar of different size can also be used for the anti-vibration of seabed suspended span cable, high hollow tube-like structure thing.
