Description
Technical field
The present invention relates to maritime traffic means of transport field, relate in particular to a kind of navigation air cushion liquid magnetic compass.
Background technology
There is open defect in the liquid magnetic compass of using in navigation at present: sieve basin casing component of compass is many, often occurs leakage problem; Between the carrying plane of compass scale and pivot, have friction force, thereby all there is certain frictional error in new, old compass; When boats and ships navigate by water in high sea, sieve basin rocking tendency is large, and compass scale rocks obviously, and compass points to stabilizing power extreme difference; When adjust compass heeling deviation, also do not have at present simple and efficient, intuitively measure magnetic force to instrument.
Summary of the invention
The object of this invention is to provide a kind of navigation air cushion liquid magnetic compass, is also to carry out structure, principle, member by the navigation liquid magnetic compass to current to innovate, and produces a kind of renewal product of performance brilliance.By changing the inner structure of sieve basin, and adopt hermetically sealed transparent rigid body that assembly that same material makes fusion form, exquisitely carved attractive in appearance, reach without leakage object forever; By changing sieve basin inner structure, the gas of sieve basin internal upper part both can be stretched and prevented that sieve basin shell was split up, be used for again air cushion, row moves compass liquid and makes the floating assembly of compass entirely float and be stabilized in sieve basin, the frictional error that not only reaches compass is very little and negligible, and has simplified the inner structure of sieve basin; By setting up righting ball and making righting ball and sieve basin synchronous rotary, in the time that sieve basin swings, righting ball has the performance of very strong righting and stable sieve basin; Magnetic force by exploitation of innovation, can quickness and high efficiency ground correct tilt autodyne to the heeling deviation Special tool for correcting of indicator.
The object of the invention is to be achieved through the following technical solutions:
A kind of navigation air cushion liquid magnetic compass, comprises binnacle, binnacle internal partition, the outer flange of binnacle, compass deviation means for correcting, sieve basin righting ball, basin ball line, upper gimbal, lower gimbal, magnetic force indicator; On described binnacle internal partition He on outer flange, be equipped with compass deviation means for correcting, described sieve basin is fixed on binnacle internal upper part by upper gimbal, righting ball is fixed on bottom in binnacle by lower gimbal, sieve basin is connected by basin ball line with righting ball, and forming synchronous rotary, righting ball can play righting and stable sieve basin.Described sieve basin shell is the assembly hermetically sealed transparent steel body that also fusion forms that adopts same material to make, and is filled with flexible gas in sieve basin, and sieve basin shell can not be split up.
The inside of described sieve basin comprises fixation kit, floating assembly, compass liquid, flexible gas, and fixation kit comprises annular control chamber, cylindricality control chamber, broad wool breeder tube, the damping sheet in annular control chamber, aperture, lubber line mark circle, sieve basin central shaft; Floating assembly comprises compass scale, fixed buoyancy chamber, scale center pit jacket layer, compass magnet steel, automatically controls float.In annular control chamber, be provided with horizontal damping plate, also can establish vertical damping plate, when normal use, by handstand sieve basin, gas is imported in cylindricality control chamber and annular control chamber, automatically the middle part of controlling float by designing requirement just floats on the liquid level of cylindricality control chamber, sieve basin central shaft is through the hole of the scale center pit jacket layer of floating assembly, and the floating component level of restriction moves.Designing requirement 1: the gross mass of compass liquid in sieve basin and the ratio of the gross mass of floating assembly equal compass liquid at the total area of the top gas-liquid interface of annular control chamber and cylindricality control chamber and automatically controls the stage casing of float at the ratio of the area of section at compass liquid liquid level place, and annular control chamber, cylindricality control chamber, connect with broad wool breeder tube, its objective is that to reach the floating height and position of assembly of compass irrelevant and stablize with the transformation temperature of compass liquid.Designing requirement 2: the center of gravity of floating assembly is under the centre of buoyancy of floating assembly, but the distance of disloyalty is unsuitable excessive, the rotary inertia size of floating assembly scale length hunting period actual needs and determine per compass, its object makes floating assembly minimizing shaking amplitude and stablizes.This structure object makes compass frictional error very little negligible.
Described sieve basin righting bag is drawn together righting ball shell, interior ectosphere connecting link, upper flexible hemisphere, lower flexible hemisphere, the flexible gas of righting ball, righting ball liquid, righting ball damping fin composition.Aufbauprinciple: in sieve basin righting ball is connected by righting ball shell hemisphere face, the assembly of flexible hemisphere fuses the hermetically sealed righting ball shell forming, and is furnished with righting ball damping fin on sieve basin righting ball outer casing inner wall.Crossing point of axes is overlapping in length and breadth for sieve basin righting geometry of sphere centre of sphere and lower gimbal, in the time of Ship Swaying, righting ball liquid only has translation there is no turn, sieve basin line end is connected and synchronous rotary by basin ball line with sieve basin righting ball line end, and in the time that sieve basin rocks, righting ball has the effect of very strong righting and stable sieve basin.Sieve basin, righting ball center of gravity are respectively a little less than upper and lower gimbal crossing point of axes in length and breadth, and between gimbal frame axle and bearing, rotational resistance is minimum, its objective is and make in the time of Ship Swaying, and sieve basin, righting ball can not produce large turning moment and can be kept upright again.
Described magnetic force director comprises floating plate, Y shape frame, underframe hole seat, indicator liquid, indicator container, magnetic dip baseline, indicator magnet steel.Design concept is that Y shape frame floats in indicator liquid entirely, and Y shape frame is fixed in the hole of underframe hole seat, and Y shape frame can freely rotate along surface level 360 degree; Floating plate floats in the Y shape frame groove in indicator liquid in the magnetic force situation of disregarding magnet steel, also can centered by floating plate axis, carry out free rotation, the magnetic force that at this moment magnet steel direction represents this position to.It is all symmetrical in floating plate central shaft bobbin central point that technical requirement floating plate requires its geometric configuration mass distribution, and the central point of indicator magnet steel is just positioned on the central point of floating plate axle.The axle of indicator magnet steel is vertical with the axle of floating plate, in floating plate outer rim, be marked with magnetic dip angle index chi, can read the size of magnetic dip, in the time of adjust compass heeling deviation, take out sieve basin, magnetic force is placed on to the position of former sieve basin to indicator, and make indicator magnet steel be positioned at the magnet steel part of sieve basin, and adjust heeling deviation means for correcting and make indicator magnetic force consistent with local magnetic dip to inclination angle, proofread and correct complete.
Beneficial effect of the present invention is: described compass has that simple and compact for structure, exquisitely carved attractive in appearance, cheap, working service is convenient, dependable performance is stable, outstanding advantages is many, pointing system friction force is little, frictional error littlely extremely can be ignored, prominent advantages, it is fine that boats and ships navigate by water compass pointing stability in stormy waves, can just match with the navaid such as radar, autopilot instrument.
