Description
GUIDED SATELLITE DISK ANTENNA MOUNTING STRUCTURE
The present invention relates to a guided satellite disk antenna mounting structure which is comprised of an adjustable mounting unit, which holds the disk antenna, and a driving mechanism, which is controlled by the ground control station to turn the rotating member of the adjustable mounting unit in changing the angular position of the disk antenna subject to the degrees of latitude in geography.
Nowadays, more and more artificial satellites have been launched for the purpose of telecommunication.
Therefore, disk antennas have become more and more popular. Because artificial satellites are commonly moved around the equator, the turning angle of disk antennas has great concern with the degrees of latitude in geography, and several disk antennas must be installed when to receive signals from different artificial satellite. Therefore, the installation of regular disk antennas is complicated and expensive.
The present invention has been accomplished to provide a guided satellite disk antenna mounting structure which permits one disk antenna to receive the signals from several artificial satellites.
According to one aspect of the present invention, the guided satellite disk antenna mounting structure is comprised of an adjustable mounting unit, and a driving mechanism. The adjustable mounting unit comprises a mounting base fixed with a mounting plate and secured to a support by screws, the mounting base comprising a front coupling chamber, a pivot transversely mounted inside said front coupling chamber, two arched slots at two opposite sides of said front coupling chamber, and graduations along each arched slot on said mounting base; an oscillating member turned up and down about the pivot within the front coupling chamber of the mounting base along the arched slots on the mounting base and fixed in the desired angular position relative to the mounting base by tightening up screws, the oscillating member comprising an upright stub shaft having a flat top side, a threaded portion on the periphery of the upright stub shaft, two recessed holes on the flat top side of the upright stub shaft, a half-round groove on the flat top side of the upright stub shaft and connected between the two recessed holes, and an axle hole through the longitudinal center of the upright stub shaft; a rotating member mounted on the oscillating member and turned horizontally on its own axis, the rotating member comprising a vertical bottom shaft fastened to the axle hole on the upright stub shaft of the oscillating member, a bushing mounted around the vertical bottom shaft within the axle hole, a half-round groove at a top side thereof corresponding to the half-round groove on the upright stub shaft, a plurality of vertical holes on the half-round groove, at least one stop bolt respectively fastened to the vertical holes and projecting into the half-round groove on the upright stub shaft, two arched slots bilaterally and horizontally disposed at one end, graduations respectively made along each arched slot on the rotating member, and a transverse pivot transversely disposed at a lower elevation than the arched slots on the rotating member; a chuck fastened to the rotating member to hold a disk antenna, the chuck comprised of two jaw plates fixed together and turned about the transverse pivot on the rotating member along the arched slots on the rotating member and fixed in the desired angular position by tightening up screws; and a cover covered on the rotating member. The driving mechanism is mounted on the rotating member and controlled by a ground control station to turn said rotating member, comprising a power drive fixedly secured to the rotating member, a worm mounted on the rotating member by bearings and meshed with the threaded portion on the upright stub shaft, a transmission gear coupled between the power drive and the worm, and two contact switches respectively mounted in the recessed holes on the oscillating member and triggered by the at least one stop bolt to stop the power drive.When the power drive is controlled by the ground control station to turn the worm, the rotating member is turned horizontally on the upright stub shaft to change the angular position of the disk antenna. When one contact switch is touched by the at least one stop bolt, the power drive is stopped.
When the control switch is started again, the power drive is driven to turn the worm in the reversed direction, causing the disk antenna turned to the reversed direction. Therefore, the disk antenna can be conveniently controlled to change its angle of inclination as well as angle of trim in tracing an artificial satellite, which moves in a track.
According to another aspect of the present invention, the vertical holes on the half-round groove on the rotating member are equiangularly spaced from one another at a pitch of 10 . If only one stop bolt is installed in the midway, the rotating member is allowed to be turned within 1800. Therefore, the installation of the at least one stop bolt is done subject to the degrees of latitude in geography.
The invention will now be described further by way of example with reference to the accompanying drawings in which:
Fig. 1 is an exploded view of a guided satellite disk antenna mounting structure according to the present invention;
Fig. 2 is an installed view of the guided satellite disk antenna mounting structure shown in
Figure 1, showing the angular position of the disk antenna adjusted; and
Fig. 3 is a top plain of the oscillating member, showing the turning angle of the screw in the half-round groove between the contact switches.
Referring to Figure 1, a guided satellite disk antenna mounting structure in accordance with the present invention comprises an adjustable mounting unit 1, and a driving mechanism 2.
The adjustable mounting unit 1 comprises a mounting base 11, an oscillating member 12, a rotating member 13, a chuck 14, and a cover 15.

The mounting base 11 further comprises two arched slots 114 at two opposite sides, through which a respective screw 3 is inserted to hold down the oscillating member 12 in the desired angular position. Graduations are made along each arched slot 114 to facilitate the positioning of the oscillating member 12 in the desired angular position.
The oscillating member 12 comprises an upright stub shaft 121 having threads 122 around the periphery, two recessed holes 123 on the top side of the upright stub shaft 121 for mounting a respective contact switch 5, a half-round groove 124 connected between the top recessed holes 123, and an axle hole 125 through the longitudinal center of the upright stub shaft 121 for mounting the rotating member 13. Each contact switch 5 has a button 51 facing the half-round groove 124.
The rotating member 13 comprises a vertical bottom shaft 131 inserted through a bushing 132, which is mounted within the axle hole 125 on the upright stub shaft 121 of the oscillating member 12, and then secured in place by a locknut 133. The driving mechanism 2 is mounted on the rotating member 13, comprised of a power drive 21 fixedly secured to the top side of the rotating member 13, a worm 22 mounted on the rotating member 13 by bearings 24, and a transmission gear 23 coupled between the power drive 21 and the worm 22.The rotating member 13 further comprises a half-round groove 133 at the top side corresponding to the half-round groove 124 on the upright stub shaft 121 of the oscillating member 12, a plurality of vertical holes 134 on the half-round groove 133, a plurality of stop bolts 8 respectively fastened to the vertical holes 134 and projecting into the half-round groove 124 on the upright stub shaft 121, and two arched slots 135 bilaterally and horizontally disposed near the front end for adjusting the angular position of the chuck 14 forwards and backwards. The chuck 14 is turned about a transverse pivot 4 at the front end of the rotating member 13 and fixed in the desired angular position by screws 3, which are respectively inserted through the arched slots 135.
Graduations are made along each arched slot 135 to facilitate the positioning of the chuck 14 in the desired angular position. The chuck 14 is comprised of two jaw plates 141 fixed together to hold a disk antenna 7. An electronic device (not shown) is installed in the rotating member 13 for communication with the ground control station (this electronic device is not within the scope of the invention, therefore it is not described herein in details).
Referring to Figure 2 and Figure 1 again, the mounting base 11 is fixedly secured to a support 6 to hold the oscillating member 12, permitting the oscillating member 12 to be turned vertically about the pivot 4 along the arched slots 114 and then fixed in the desired angular position, then the contact switches 5 are respectively installed in the recessed holes 124 on the upright stub shaft 121 of the oscillating member 12, and then the rotating member 13 is fastened to the axle hole 125 on the upright stub shaft 121 of the oscillating member 12, and then the driving mechanism 2 is installed in the rotating member 13, permitting the worm 22 to mesh with the threads 122 on the upright stub shaft 121, and then mounting at least one stop bolt 8 in the vertical holes 134 on the half-round groove 133 of the rotating member 13 for controlling the rotating angle of the rotating member 13, and then the disk antenna 7 is fastened to the chuck 14 on the rotating member 13, and then the cover 15 is covered on the rotating member 13 over the driving mechanism 2.
Before the use, the angular position of the disk antenna 7 can be adjusted up and down as well as forwards and backwards by changing the angular position of the oscillating member 12 relative to the mounting base 11 and the angular position of the chuck 14 relative to the rotating member 13. When the power drive 21 is controlled by the ground control station to turn the worm 22, the rotating member 13 is turned horizontally along the threads 122 on the upright stub shaft 121 to change the angular position of the disk antenna 7. When one contact switch 5 is touched by the stop bolt 8 in the half-round groove 133, the power drive 21 is stopped. When the control switch is started again, the power drive 21 is driven to turn the worm 22 in the reversed direction, causing the disk antenna 7 turned to the reversed direction.Therefore, the disk antenna 7 can be conveniently controlled to change its angle of inclination as well as angle of trim in tracing an artificial satellite, which moves in a track.
Referring to Figure 3, the vertical holes 134 are equiangularly spaced from one another at a pitch of 100 When the stop bolt 8 is fastened to the 900 position in the midway of the half-round groove 133, the rotating member 13 is allowed to be turned horizontally with 1800. If two stop bolts 8 are respectively fastened to the left 200 position and the right 200 position, the rotating member 13 is allowed to be turned horizontally within 400 only. Therefore, the applicable turning angle of the rotating member 13 can be conveniently set subject to the degrees of latitude in geography.
