Description

Multi-satellite TV antenna

What the present invention relates to is a forward antenna assembly of TV of geostationary satellite, satellite is a geostationary satellite, that is to say with respect to the earth and fix, and be in optimum state for the possibility that makes reception, promptly in order to increase the possibility that emission receives, antenna assembly can in turn aim at those satellites, so that accept their emissions separately.

Track is the geo-stationary orbit in the plane under the line, is its center with ground ball center, and radius is 42164km, that is to say, and be for the 12756km for locating the ground bulb diameter under the line, be 35786km with respect to ground level.

Fig. 1 shows the definition earth equatorial plane, the equator, and ground ball center (O), the place (M) of laying antenna, antenna is laid vertical line and the statement that asked a question of antenna itself a little.

At present, many satellite equipments have two engines, or pass through exploration one by one, perhaps lay the distinctive memory device in place by information programme and antenna station, each satellite that can take accurate aim perhaps has single engine, but has an approximate process tracking.Therefore many satellite antennas of first kind device is very expensive, be the sky type antenna of leaving professional purpose for, and second many satellite antennas of class device is based on two kinds of different mechanism.

First kind of mechanism (Fig. 2) is to determine to lay the vertical line in place and make this rotation of day wire-wound, antenna axis moves in perpendicular to the plane of the vertical line of laying the place (MO), and along straight line (D) cutting orbit plane, therefore the aiming of satellite is very approximate, can only receive near the seldom several satellites of sagittal plane that are positioned at the earth that comprises pole axis and place, antenna station, and receive very bad.

Second kind of mechanism (Fig. 3) is to determine these same factors, a but supplementary angle that will be in the meridian plane jointed shaft of antenna and rotating shaft be tilted to lay the latitude in place, so that this axle is perpendicular to equatorial plane, and antenna axis is tilted mutually in this rotating shaft, so that antenna beam is depicted the circular cone that circles round, its under the line the mid point at the end in the plane be to lay the place projection on the plane under the line, the sweep limits of beam and orbit plane intersection are off-centre operations with respect to ground ball center.

When people wanted to aim at low a little any the satellite of a liftoff horizontal line, aiming was just more accurate but become too false, and this just must have more large-scale antenna, and those angles that will show only are suitable for the place of laying at antenna station.

In fact, in the time of satellite of aiming, this satellite constitutes greater than 15 with respect to meridian plane spends to the angle of deviation of 20 degree, collimating fault will so obviously so that it will cause or the diameter over dimensioning of parabolic antenna is processed, perhaps use a very accurate and expensive electronic equipment, or accept only selecting correctly to receive some emission under those situations that aimed at satellite in the wave beam by a small margin.Like this, those are not that the country that is just facing some satellite has just been deprived Launch Right, those countries with a vast territory (U.S., the Soviet Union, China, India etc.) or those (French Africa, area that influenced by language or interests, Muslim country with regard to religion, Japan and the Southeast Asia with regard to culture) be compulsory, perhaps can not link up, perhaps should increase forward telstar; Telecommunication satellite for specialty also is the same.

The present invention can remedy these defectives.In fact, the invention enables just target trajectory exactly of a shared engine, can show a tool be suitable for antenna lay the place latitude angle and for aim at each different satellite have separately with equipment lay the irrelevant rotation (Fig. 6) in place.Therefore, it is less that antenna just can size, lays much also simply, and is easy to realize that device can be equipped one and be enclosed within the program that factory works out in advance, because irrelevant with the place.The installation of equipment can not undertake by the people of training by one, also without measuring instrument, and last position occupation that the expert is installed is still necessary.

The method of using in order to achieve this end is as follows: antenna beam is drawn a circle in the plane under the line, and it is the geo-stationary orbit of telstar forward.Antenna beam therefore should be always one to lay the place with the antenna station be the summit, be a bus of the oblique cone of inclined shaft with the vertical line of this point by ground ball center, and as this oblique cone under the line the directrix in the plane be geo-stationary orbit.If use plane cutting this oblique cone parallel with equatorial plane, the directrix of this circular cone on this plane is that a joining with the vertical line of laying the place at this plane and antenna station is the circle at center, radius is proportional, so that these two parts of circular cone (set out be limited in determined part between this track and the summit and be limited in determined part between this track and the summit and be limited in being parallel to that plane of equatorial plane and the part between the summit by geo-stationary orbit) be with the summit be the center and with the radius of the earth divided by being like the ratio position with the distance of the intersection point of the vertical line of laying the place from conical tip to this plane that is parallel to equatorial plane, this position may be positive or negative (Fig. 4) like property.

The mechanism that can reach this purpose Fig. 8 forms according to following universal model, and vertical axis is by fixing a pillar 1 and a micro-tensioning system is set up at device.On this axle, two fixing point A and M are specialized.At the M point, make a D wind axle perpendicular to meridian plane and rotate and equal the angle at supplementary angle that antenna is laid the latitude in place, so that axle D is perpendicular to equatorial plane.Be subjected to 1 B of D constraint around this rotation the time, to draw one with round like the synchronous position, pavilion road.People force the paraboloidal axle of antenna always by some A and some B, and this straight line AB just in time is a bus of the oblique cone of regulation in a section in front.If parabola is so-called " biasing ", that is to say, if its fixed pan is not orthogonal to the symmetry axis (antenna is just in this plane) of the paraboloidal endless that circles round but is oblique, just should make this plane the device on a reverse inclination angle is arranged so that make this turn back to along or be parallel on the direction of AB.Especially under the situation of " biasing " antenna, it is important a plane of antenna, for example symmetrical plane always remains parallel to itself in the process that moves.In order to reach this purpose, antenna holder should only have two kinds of rotations, for example vertical and a plane of symmetry that falls in an antenna level, rather than three kinds of rotations; This is more logical in any case, because two kinds of energy of rotations are determined straight line in the space.At the B point, connection between antenna holder and arm BM should allow three kinds of rotations and a kind of translation freely carry out, form around the rotation of straight line D in two kinds of rotations of these three kinds of rotations by branch line AB, be mostly that because of having fixing limit AM of two length and the triangle AMB of a BM and a variable angle ABM be deformable and put down.The method of Que Dinging is placed into the symmetrical plane of offset antenna on the direction that is parallel to the vertical line of laying the place like this.Under people wanted this plane of symmetry of antenna always to keep perpendicular to orbit plane and with respect to this track to be radially such a case, the rotating shaft MB of harmony axle AB and tracking system was installed with a sliding connector perpendicular to the latter (Fig. 9) together.

Because two circular cones are like the position, be identical in perpendicular to the plane of straight line D around the angle of M point rotation in order to carry out the transition on another satellite in the plane under the line from a satellite around angle that ground ball center rotates and B point.Because those satellites are fixed with respect to the earth, those rotations of determining like this on device are also fixed itself, and with device lay place irrelevant (Fig. 6).Therefore can program to rotation in advance during fabrication, only be left to have determined zero point to program according to the longitude of laying a little.Therefore such device only has the two kinds of adjustings that will carry out: the rotating shaft of straight line D is placed on device lays in the meridian plane in place, regulate the inclination angle of D according to an equal angle of the supplementary angle of the latitude of laying the place.It may be easy that adjusting in meridian plane is carried out as follows: around laying the vertical line tumbler in place, carry out after the point of theory that demonstrates this satellite about intercepting the adjusting of a satellite again, and fix the motion of device thereupon.Adjustment is envisioned for so obtains, when specialize lay the vertical line in place after, when showing the angle of being sought, by means of a method vernier scale or other mechanics or vision, or by means of a stepping motor or coordinate converter by using message count instrument especially, so a kind of such product can be sold in megastore.

Hope also will be meticulousr aiming so that consider under the situation of defective of circle of the earth, people make AM in (and being vertical under the normal condition) the very little correction angle that tilts in the meridian plane on the one hand, and on the other hand, can equip the little high device of a MB to antenna assembly, some numerical tabulars thereby be necessary, but the quality of aiming is absolute perfect, except the shortcoming that is caused by setter.

Satellite is the antenna assembly of TV forward, be characterized in the mechanism that can make antenna beam draw an oblique cone, this circular cone is the summit with the place of laying of equipment, is inclined shaft with the vertical line in this place by ground ball center, is directrix with the geo-stationary orbit of satellite; Device has the vertical axle that is conditioned for this reason, two concrete fixed points are arranged on this, one is the summit A of circular cone, another is that a M point apart from d is arranged from this summit, this point determines that a position equals the radius of d divided by the earth like the ratio of property, an axle D is through the M point, and can in meridian plane, be tilted an angle, this angle be laying of antenna station the supplementary angle of the angle of latitude of narrowing, and around a length of this rotation arm MB that is r (d and r are proportional with the radius of the radius of the earth and geo-stationary orbit respectively), simultaneously just draw out the round C that a center is M in the plane of geo-stationary orbit being parallel to, settle wave beam along straight line AB or along the straight line that is parallel to this straight line, this wave beam draws and is related to the circular cone of track, by summit A, axle AMO and circle C are the oblique cone determined of directrix be d divided by the radius of the earth with the track circular cone is like the ratio position, and this position may be positive or (Fig. 8) that bear like property.

In order to consider the true body of the earth, people have determined some numerical tabulars, vertical axis are tilted in meridian plane, so that vertical axis comprises the center of the earth veritably.Angle of sloping shaft D in meridian plane (front is determined), owing to consider the actual latitude in place, and the length of regulating arm MB, so that take accurate aim very much track.

In order to make device have the linear rule of rotation with respect to control, and in order to ensure the irreversibility of motion, make homing position fix and the energy wind resistance, these are all irrelevant with control, those terminal parts that move control are realized by worm gear system, the ratio of the gear teeth and module makes enough accurate a deceleration, by showing the rotation of screw simply, the precision that obtains aiming at.The gear teeth of worm gear system and module be than making the gear teeth that an irreversibility and the enough mechanical resistance strong wind with the exception of per hour resisting 160km be arranged, only with independent device or replenish under the situation of a fixture again.

Device only has three adjustings, the first forms the adjusting of the perpendicularity that has bearing pin 3 of straight line AM, another is the orientation of laying the symmetrical plane that installs in the meridian plane in place at the antenna station, last is to lay the lifting of the supplementary angle of the latitude in place carrying out according to the antenna station to regulate, these are regulated all is simple, without any need for special equipment.Except the equipment of device supply.Because machinery is adjusted in factory, AM realizes after aiming is regulated and aimed at a satellite in the fine setting in the meridian plane on the extended line of shouldered pin.

In order to meet the responsibility of very strict particulars of sale regulation; about facing near child or domestic animal; the safety issue of operation is about anti-bad weather with about the implantation in the face of vegetable remains and some toys (insect, birds etc.); the maintenance problem of machinery; device is by a casing system protection, and the casing system reduces its chance in wind, has so just protected those dangerous parts of machinery; and guarantee enough water proofing properties, to guarantee to realize the responsibility of this particulars of sale regulation.

First example (Figure 11 is to Figure 16) of realizing.Vertical axis is that the support 4 by a pillar 1 and a proper device constitutes, and pillar can be installed in the garden, on the roof, on balcony, or the front in house.Pillar has a hoop on its top, three screw holes of 120 ° of being separated by are arranged on hoop, and all holes are all on a circle of pillar, and a screw hole is arranged in central authorities.The support 4 of device has four smooth holes and is suitable for four screw holes of pillar and three screw holes so that tightens in those screw holes of support by three pressure screws, people can make the direction of appliance stand change, and by four rigging screws this support is fixed on the support, four screws are tightened in four holes of pillar.This support has the bore hole of a standard, be connected with the dismountable pin of antenna assembly so that realize, and be exactly that this axle corrects angular adjustment by vertical adjusting or along one, axle by a shouldered pin, device connects together securely with this support, match with the aperture of support, and by for example pressure screw, a kind of anchor clamps or tangent feeler gauge are fastened on its position.

The adjusting of the perpendicularity of pillar and the adjusting of antenna holder, the symmetrical plane of device is all monitored by the level meter-compass 5 of a precision with the parallel of meridian plane of location of the machine to be installed, it is the air-bubble level formation with the radius of curvature on the horizontal plane of bubble of a circle, and it can judge 1/100 degree (radius is more than or equal to 1.5 meters).Comprise a unsteady needle in the bubble and form compass.For the spheroid form of considering the earth when doing meticulous adjusting, this level meter is attached to its lower surface on the supporting surface in the support of antenna of axle of shouldered pin of proper device, the bore hole of this face and support is owing to be fully vertical, be engraved in limbus graticule on the transparent upper surface of level meter guarantee antenna holder bore hole spool in the meridian plane of laying the place of equipment, the tilt possibility of an angle correction of perpendicularity.

Connection between parabolic support and device is realized by two movable joints, one to be vertical pivot be known as between intermediary's part of support casing 6 the axle 3 of the shouldered pin of proper device (and and the latter be conllinear) and one, and another is shell-like 24 at support casing 6 with have between the parabola support 7 of out-of-level axle so that these two axles are intersected in the A point of stipulating previously.These movable joints can be realized by some axle bushes or some ball bearings of for example sealing.

The shouldered pin 3 of device has a shell-like movable joint, the latitude sloping shaft 8 of trunnion axis and framework is connected together, this axle with the shouldered pin cylinder of this same part crosses, and this point is exactly the M point that the front is determined, one distance is arranged as the length A M that is determined by part integral body with the tenon shoulder; These parts are axles of the shouldered pin of proper device, axle sleeve, parabolic support and the articulated axle that is connected shouldered pin and latitude sloping shaft.

The shouldered pin of latitude sloping shaft 8 (Figure 11) and proper device has the pivot of the tracking system 9 of the movable joint of the band cover of determining a front and the cylinder formation that one is with the standard cotter pin together, this cylinder is perpendicular to its band cover movable joint axle, in the plane of symmetry of cover.

Tracking system 9 (Figure 10 and Figure 12) comprises the bore hole that has pin of a standard, form the pivotally connected of a realization with the latitude sloping shaft by for example axle bush or bearing, chute 10 with the vertical axis of a tracking system 9, its symmetrical plane comprises this axle, the feasible ball-and-socket joint supporting member 11 that can accept to form the connection B that determines the front.

Form to connect the ball-and-socket joint supporting member 11 (Figure 13 and Figure 10) of B but have a slide block to settle down in the chute of the tracking system of scalable and fixed position, there is one to be parallel to the bore hole of slide block and in the symmetrical plane of this slide block, to accept a ball-and-socket joint 12 special or spill that buy in market (Figure 10), so that the pivot of the zero latitude sloping shaft of the axle that the center of that ball-and-socket joint is connected with the tape spool cover has a distance abreast, the axle that this tape spool cover connects links to each other with the shouldered pin of proper device, and the center of ball-and-socket joint and this pivot vertically have a distance in the symmetrical plane of tracking system, so that ratio AM/BM equals the ratio of earth radius and geo-stationary orbit radius.

Parabolic support 7 vertically and has the bore hole of a standard with crossing in its symmetrical plane, it accepts the axle 13 of a standard, this forms completely detachable connection with bore hole, this freely slides in the hollow ball-and-socket joint of being determined by the front, there is a parabolic fixed platform to be parallel to the axle of this support casing, the plane that forms with respect to the axle and the standard bore hole of this support by this cover, its inclination angle is that a fixing angle equals 90 ° for the parabola of those symmetries, it is parabolical perhaps to be known as " biasing " for those, its inclination angle is an angle that equals " biasing " angle, the pivot that the axle of a cover that is parallel to this parabolic support is perhaps arranged, therefore accept one to the distinctive adapter of the parabolic type that is used, the supporting surface of this adapter and the locking of this adapter and adjusting device.

The tilting gearing of sloping shaft realizes that by means of a worm gear system 14 (Figure 10) accuracy that its deceleration device with vernier scale that is connected with screw can show is 1/100 degree.This system is irreversible, and is replenished completely by the lock-screw 15 of a fixed position, makes it possible to take in the effect of most bad weather to antenna, thereby for smaller volume, drag and keep the ability of original position to be eager to excel.Device is adjusted when assembling in factory, so that the pivot of tilting gearing is parallel to the axle of the shouldered pin of proper antenna assembly.

Mobile control with respect to sloping shaft is to realize by means of output device 16 and a decelerator 17 of a gear-screw rod.Its middle gear and sloping shaft connect together, and screw rod with tracking system have one pivotally connected, or gear drive, or second gear-screw rod system, its input parts are stepping motors 18, electronic casing is ined succession tracking system so that each step rotation of motor is rotated an angle corresponding to tracking system with respect to sloping shaft, and is better less than 1/100 degree.

Connection B between tracking system and parabolic support can realize by two orthogonal connection pivots 19, the tracking rotating shaft perpendicular to sloping shaft of a level, and perpendicular to it symmetrical plane and intermediary's part together, another vertical connecting axle is vertical in the horizontal level of antenna beam, be called this intermediary's part and one between the axle of harmony, this is worn the pivot of the hole of a level perpendicular to tracking system, all such axles are owing to all be intersected in mathematical point B in the symmetrical plane of tracking system, so just realize a kind of being rotationally connected and a translation (Figure 31 of three degree of freedom that have along MB, 32,33).

If want paraboloidal symmetrical plane always to keep perpendicular to orbit plane, in second key diagram, adorning a chute perpendicular to the rotating shaft of tracking system in the earlier paragraphs on the determined coordination axle connects, its sliding axle with a standard axle in the symmetrical plane of this system, its shape be complementary part with being known as parabolic support have one pivotally connected, therefore parabola is connected on this standard axle fully, being connected in the support on this fully and being suitable for parabola (Fig. 9 of every kind of model and specification with a standard, Figure 31, Figure 32, Figure 33).

Relevant position this means if the position seemingly is positive like being positive or negative, mathematical point A just above mathematical point M, and connector B with respect to by axle sleeve 6 and shouldered pin spools 3 between the straight line AM that constitutes of rotation axis, be positioned at paraboloidal the same side; On the throne like under the negative situation, M point A order above, connector B and parabola are distributed in the both sides of vertical line AM.

Under situation like a kind of normotopia, shell guarantees the safety for child, adult and domestic animal simultaneously, reduces the chance that wind-engaging attacks, in the face of bad weather, and vegetable remains thing and toy (insect etc.) protection machinery.Shell generally is spherical, it is centered close to the A point of machinery, be two

hollow hemispheres

20 and 21, a hemisphere concealment is in another, and its in conjunction with the plane be oblique and perpendicular to the device symmetrical plane, for the forefield that makes antenna can be accepted one by the projection of boring, this protective cover is aligned in frame put, and this part is fixed on the stock with two hold-down screws.An opening in symmetrical plane is in order to make the standard axle that forms connector B with ball-and-socket joint can pass through this opening, and this opening has one for block water, snow, and residual thing enters the outside hoop in the machinery.Allow the water of condensation flow out in the hole of the bottom of this protective cover.Another part of protective cover is hemispheric, compares without any special details with its opposite except disappearance.

Parabolic support has a spherical part 24 topped mouths of opening on protective cover, in order to guarantee sealing with gap and baffle plate between protective cover and support.

Under situation like a kind of normotopia; in a kind of modification; shell generally is spherical as the front, but except parabolic support is provided the protection; at first inner one second protective cover in addition; be the part sphere, on the projection of following the tracks of support, this makes the connection between support and the hoop therefore be formed with the double-deck baffle plate of sealing function; the amplitude of spherical part is such, and the opening of main protective cover always " is closed ".

Under situation like a kind of negative position, shell is to be made of a general main protective cover spherical in shape, is used for fixing at the bed course that is fixed on the parabola support by a tunnel-like and replenishes.This protection is covered with a big opening with internal hoop, and in this protective cover, intermediary's protective cover of a sphere freely slides in groove, and in its bottom a big opening with outside hoop is arranged.In second protective cover, have the 3rd spherical protective cover be placed in device shouldered pin the axle on, that tighten with one or paste flange and an outside hoop, so that with respect to the motion of these protective covers all by they separately hoop drive, the amplitude of these motions is consistent with the possibility of protective cover.The centre of sphere of these protective covers overlaps with the A point of machinery.

Under situation like a kind of negative position, in a kind of modification, shell is made of an exterior protection cover divided into two parts, a top part keeps spherical, be secured on the parabola support by a tunnel-shaped bed course prolongation, another part is connected by screw or jockey, be one hemispheric, a big lower openings is arranged, make part that the relative gap of moving about be arranged, an internal Protection cover is connected in by a flange that tighten or that be stained with on the axle of shouldered pin, and the lower openings of the always topped exterior protection cover of this spherical protective cover is to guarantee sealing, and the center of these balls all overlaps with the A point.

Under situation like a kind of negative position, in a kind of modification, the axle of shouldered pin can be a deflection, and separated into two parts, strictly couple together between them, so that shell can be realized with the cover of the outside of ball portion in two, connect together with screw or jockey between them, its part near apart from parabola is equipped with a flange, on the terminal part of tightening or be pasted and fixed on shouldered pin, second half protection is covered with a big opening, it can make the standard axle that forms connector B pass through, and by being connected on the support of tracking system at a flange on the ball-and-socket joint level, this second protective cover is in the overall process of the relative motion of each part of machinery with the method for tightening or pasting for the anti-cover of the sphere of second inside, sealing the opening of exterior protection cover, so that guarantee its sealing with narrow passage always.The center of these protective covers is on the M of machinery point; parabolic support can have the outside bed course of a sphere to guarantee the protection to protective cover and machinery, is the flange that is connected and the paraboloidal fixed head of frame shell-like for flange and those of connecting band ball-and-socket nodal axisn.

In a kind of negative position like under the situation of property, in a kind of modification, shell can be realized with a spherical protective cover divided into two parts, connect with screw or jockey between these two parts, its underpart has a flange to be in the vertical axis of frame cover and use screw, and methods such as clamping or stickup are connected frame and put.In the symmetrical plane of machinery, also have one and observe poroid opening, for the standard axle that can convey ball-and-socket joint formation connector B passes through, this inspection hole receives a lid to be passed through by this axle, its bed course of also accepting to be connected with other function surface of parabolic support.The center of this protective cover is at the A of machinery point.

Rotate, translation, some valve rubbers of columniform or spiral nappa tiger shape can be installed, in order to improve sealing and to supply sealing, under the situation of protective cover exterior mechanical part.

All not protected friction surfaces all are equipped with baffle plate and stop that humidity enters.

The machinery integral building can be: perhaps in the inside of shell, or frame overlaps and is connected the outside of shell.

Paraboloidal fixedly is to realize with the paraboloidal part that adapts to various models.The method that these adaptive parts have a kind of uniqueness with four screw on the support that " biasing " tilts, this support is hinged along an axle of the axle that is parallel to parabolic support frame inner room connection, this fixedly is adjustable, but and on a plane of parabolic support the fixed position, parabolic support plane is perpendicular to by the definite plane of the axle that is connected between the axle of the standard that forms connector B with ball-and-socket joint and frame cover and parabolic support and perpendicular to the symmetrical plane of machinery.

Those proprietary adaptive parts of each antenna are regulated with the cushion block of screw or variable thickness subtly with respect to parabolic supporting plate, these cushion blocks be embedded into these adaptive fixture upper screw around, this defective of making of compensation part.

Various solutions all can be taken into account fully, or with assembly, or, do not hinder the good operation of machinery with the part assembling.

Device has a whole set of size grades or the size grades of some part is only arranged, and from the resistive drag force viewpoint but also from aesthetic view point, the motorization viewpoint was fit to the parabolic antenna of various sizes for not only.

Even in the enforcement of connection, structure and annex, have tangible different, also can be at this point and constitute novelty and invention.

Now, several other non-restrictive example are arranged here, in their selections like symbol or other part solution on the throne architectural difference is arranged.

First kind of modification (seeing Figure 17 and 18) has positive position like feature.

Be fixed on garden, balcony, the roof or the mast 23 on the vertical wall is used in that level meter that draw and that provide is transferred to vertically approx on another physical features.On this mast, proper three pressure screws of bracing frame 21 usefulness and precision level are regulated subtly, and the accuracy of level meter reading is 0.01 number of degrees magnitude; Then, this bracing frame is fixed on the mast by means of three hold-down screws 22.

The 7th kind of modification (seeing Figure 31,32,33) is characterised in that the modification to various other schemes, and applicable to all schemes, therefore various solution methods may all be in the condition that therefore is modified.

This modification is applicable to whole schematic diagrams (Fig. 6 and Fig. 9).

Height adjusting system has been reversed, not the gear that is connected the rising back shaft to be arranged and in other words, follow the tracks of on the support but this screw rod has a pivotally connected and gear to be connected direction with the rising back shaft by a pivotally connected screw rod that is connected on the direction track frame.This solution has been simplified the enforcement of part widely, both to the rising support, again the assembling of direction tracking support has been simplified.

It is not to have one and the bar that is connected antenna holder slip ball-and-socket joint connection together with antenna holder that direction is followed the tracks of support, but one dual pivotally connected: one of be perpendicular to aforesaid bar and perpendicular to the symmetrical plane of motor bracket, its two be the axle be slidingly connected, be connected in the axle of the bar on the antenna holder.This makes and can reduce cost greatly and reduce the couple that the junction antenna of this antenna holder in the frame cover waves greatly under wind action.

These different modifications can be the use that also separates that takes into account to same scheme.

Decelerator here is that installation that be determined and adjusting screw(rod) and direction tracking also is determined.

The 8th kind of modification (seeing Fig. 9,36 to 42) is identical with scheme (seeing Figure 10 to 16) on its structure and general solution, but is different about connector B and

parabolic support.Part

11,13,12 with go-no-go the axle be connected B on the whole, as to the 7th kind of modification (Figure 31,32,33) equally be implemented, for example have a longitudinal key and form a chute with the bookkeeping axle and connect but decide the bore axle, it is placed in this symmetrical plane in the symmetrical plane of tracking system.Therefore, this symmetrical plane of deciding the bore axle always keeps the shaft parallel with tracking system, that is to say vertical with the common plane in the geo-stationary orbit of satellite and equator.Decide the bore axle with intermediary's part 20 have one for example by means of two self-lubricating bearings realize pivotally connected, and it is connected on the antenna holder 7 fully.Intermediary's part 20 and frame cover 6 have together one pivotally connected and and this cover together as the sealing function that an opening is arranged in scheme (Figure 10 to 16) lining.

Figure 34 and Figure 35 represent to have an example of two row gear reduction unit motors of screw rod outlet.

In a word, antenna assembly comprises: the axle 3 of a shouldered pin, can be with a proper appliance stand 4 by vertical direction ground adjusting subtly, one be hinged on these frame cover 6 usefulness on 3 it spool intersection point determine a fixing point A, one flatly is hinged on axle 3 the M point and is conditioned so that the latitude vertical with equatorial plane 8 sloping shaft D, a tracking system 9 on every side that is hinged on D is overlapped the linear fitting B that 6 hinged parabolic supports 7 have an annular with frame, a whole set of protection and safe hood are so that the motion of machinery produces a positive or negative position seemingly, using by the definite track circular cone of its summit A is center A, lay the axle of the vertical curve in place for it, with the geo-stationary orbit with satellite be its directrix, ratio AM/BM with earth radius the same with the ratio of orbit radius.

Proper appliance stand 4 comprises a pedestal, and it accepts to be fixed on the hold-down screw on the pillar and the adjustment screw of vertically spending and a vertical bore hole of accepting the axle 3 of shouldered pin; The axle of shouldered pin comprises two coaxial vertical cylinders, one is placed 4 li of bore holes, another is hinged on the frame cover 6 as universal joint, the bore hole of a level receives the rotating shaft of latitude sloping shaft 8 and the mounting yoke of a worm Gear-Worm tilting gearing 14, sloping shaft 8 comprises the pivot (linearity that tracking system 9 has annular connects B and receives worm Gear-Worm system 16 and its decelerator groups of motors 18) of a receiving and tracking system 9, be hinged on the frame cover 6 of axle on 3 vertically and connector in frame cover place one level arranged with parabola support 7, the parabola support have one in the vertical bar at frame cover place and junction on axle, the linearity of receiving ring-type that is coupling at frame cover place connects, and parabola support 7 also has a supporting plane perpendicular to the peculiar coupling part of each parabola of this bar.

Tracking system 9 that B is ordered and the annular linear fitting between the parabola support 7 can with a fixing different guide rail adjust position (along the BM section) changes simultaneously the position like ratio and along local latitude inclined belt cotter pin spools 3 so that be suitable for the actual level surface of the earth.

Tilt adjustments obtains with the fixed worm Gear-Worm of pressure screw 15 system 14 by means of one, the moving then of tracking system obtained by means of a worm Gear-Worm system that is subjected to motor 18 controls of a decelerator and a controlled rotation, the motor 18 of controlled rotation makes it maintain static and makes it that a machinery group power that has nothing to do with driving power be arranged, guarantee the safety when being subjected to speed per hour and reaching the attack of blast of 160KM/H, and enough speed reducing ratio, with guarantee by screw or motor according to a kind of rotation and the simple rotation of the linear rule between the rotation of wheel and connected parts precision that just can reach the aiming 1 of 3/100 degree at screw or motor.

In order to ensure accurate three kinds of adjustings of aiming satellite is enough: the adjusting of perpendicularity that at first is the axle 3 of the shouldered pin obtained by the level compass 5 of a sphere, this spherical level compass can be judged the deflection of one 1/100 degree by three pressure screws between pillar and proper appliance stand 4, and is fixed by four hold-down screws; Next is the meridional plane orientation of laying the place towards the symmetrical plane of device, 3 one rotation of axle of axle with shouldered pin around the vertical adjusting of the quilt of the bore hole of proper appliance stand 4, and with a pressure screw, pliers, tangential feeler gauge etc. makes it to maintain static.Be by to the aiming of a satellite and the meticulous adjusting of adjustment at last, by satellite being regulated with a worm Gear-Worm system and by means of the demonstration at the supplementary angle of the latitude of laying the place of the fixing latitude sloping shaft 8 of a pressure screw, machinery has been transferred to zero in factory, axle D is on the extended line of axle 3, and annular linear fitting B is in the symmetrical plane of device.

The casing system is by generally being that hemispheric two parts constitute, connect with backing plate between them or tighten that screw links up, the center of these two parts or A point, one of them is connected on the frame cover 6, or M point, main casing is connected in or frame overlaps on 6, and perhaps on the axle 13 of shouldered pin, another casing slides and links to each other with parabola support 7.The shape of the complementation of other part; the joint of some sealing gaskets or some multilayer foldings carries out the complete closure of this mechanism; the protection of assurance mechanism is in case bad weather, plant and relic, the invasion and attack of insect and toy and the protection that moves in the face of people, child or domestic animal.

Want paraboloidal symmetrical plane always to keep seeing Fig. 9 under the situation vertical people with orbit plane, parabola support 7 has a pivot connector of ordering by the A of device with paraboloidal fixed head in its symmetrical plane, this plate has the connection of a three degree of freedom with tracking system 9: the firstth and connecting rod do translation along aforementioned pivotal line together, the secondth, connecting rod and with the axis framework of the vertical and junction of axle of front between rotation, the 3rd then be framework and and the trihedral tracking system 9 in axle formation right angle of front between rotation.

Machinery can be fully in the inside of hood, or frame cover and its connector are all in the outside of hood.

Paraboloidal fixedly is to use the part that mates according to various parabolic model to realize, these parts have the fixation of four hold-down screws of usefulness uniqueness on " compensation " tilt stand that is hinged, this " compensation " tilt stand along one with frame cover and parabola support between the axle that is connected parallel axle be hinged, parabola be adjustable and on the plane of parabola support the fixed position, this plane is perpendicular to the plane of being determined by the axle of the connecting rod of accepting ring-type linear fitting B.

Those special-purpose next parts that mate with each parabola are regulated subtly in parabola supporting bracket 7 usefulness screws or adjusting cushion block mutually, compensate paraboloidal those manufacturing defect by these being adapted to part on every side attached to hold-down screw.

For satisfy some more specifically needs (Northern European countries, specialty use) need to change homing position to the neighborhood that is positioned at a mean place on the geo-stationary orbit.

For this reason, two kinds of methods are equipped with this antenna:

1) people can make the elevation angle regulate motorization this can aim at any position of satellite.At this moment this device lose can be in factory the principal character of programmed in advance because the elevation angle on the track is distinctive to laying the place.

2) people can (Figure 44 to 52) directly not be connected tracking system with proper appliance stand, but will embed intermediary's parts 19 at an adjustable track elevation angle.With an axle △ ₂Horizontal loose joint joint and perpendicular to the rotating shaft △ of tracking system 9 ₁, people can change mean orbit plane aiming operation up and down.By centering on △ ₁Rotation α ' at A ₁The place is on average aimed at, and people guide to B to aiming ₁With △ ₂Guide to △ ₂', by β ' at △ ₂' rotating people the P point guided in aiming on every side.Because the aiming of device mechanism and satellite is the center with A is like the position, and identical rotating shaft seemingly can have the accurate aiming of satellite in identical deduction angle of property with this on its orbital cycle.

By a two deceleration worm and gear, for example cooperate a stepper motor again, the new rotating shaft △ between 9 and 19 ₂Be motorized, have pulse to calculate again, make the anglec of rotation meet linear rule along with the rotation of motor.Orthogonal being rotated on the orthonormal axle realized by two in the location of aiming on the track circle, therefore, and in order to determine that the equational use of track circle information programme track circle has been greatly simplified.

This solution makes basic actual tracking means keep principal character:

-install easily, can sell by kit;

-aiming is accurately absolute;

The sequencing in advance and the Unit Installation place of-the special track that carries out in factory are irrelevant.

It is identical on the reference axis that reduces cost with the specification procedure equation group that two motor reducer systems of 20.21 are regulated at tracking

system

16,18 and the track elevation angle.

For reducing by two production cost of products, most of common part are retained between basic tracking system of the public and special using system (geo-stationary orbit).

With the same in base apparatus, parts 19 have kept the connection the same with proper antenna holder 7.

In military purposes, public security, under the operating position of movable dwellings or camping vehicle, such antenna can be fixedly mounted on the standby car, for example " jeep " type or be positioned at least on the anchor post pedestal on the car.

The Gulf War and some natural calamities show that the communication level also has very big gap, show also that simultaneously some plans of finding on the spot, document, strategy, material use the possibility that directly reaches, but do not know that simple and unadorned daily life equipment that stage of rescue team member, mechanical drawing knowledge (Tchernobyl) geology landform etc. and motoring has a rest all may obtain the advantage that the plan much much effective and quick participates in and the advantage of reception.

Since equipment be fix or at least pillar be to be fixedly mounted in (Figure 53) on the automobile therefore to there is no need on device, to keep the fine tuning of vertical degree because the parking landform of automobile unusual level not, regulate simple how faster (universal joint 1 is between the fixed support and first radius arm 3, another 2 between this radius arm 3 and second radius arm 4) by obtain this with respect to two

universal joints

1 and 2 of automobile axle vertical and level.These connectors make they adjusting and be fixed on ± 45 ° amplitude range in, lay those places of vehicle in order to consider people.Regulate and obtain with two

spirit levels

5 and 6 that are installed on the radius arm.

The top of device or proper device can be torn open in vehicle and happen frequently so that more not noticeable or better on the highway or advance in the place of stopping up or pass through in plant in great numbers.

Stop the back less than five minutes at vehicle by this way, those take the people just can be directly with those important country contacts, receive some plans, file, using method, nuclear power station sketch and key point, the image of target etc., so that by means of the satellite image that sends from a broadcasting unit, finish their task better.This broadcasting unit itself receives control centre or spy satellite TV image forward or the broadcasting of watching them to like more simply.

It is effective especially that this application can seem, breaks out in fire, earthquake, volcano, conflagration, nuclear accident and for Military Application (Somalia, Yugoslavia ...) or in order to utilize his vacation.

Different schemes is can be whole or in part compatible and the function that do not hinder mechanism in different connections, in the enforcement of structure etc., even tangible difference is arranged, also can not constitute the novelty of present patent application, because their motion principle is identical.
