Abstract
The utility model relates to a polar axis type electric satellite antenna spinner used for the rotation of the satellite antenna, which comprises a trigonal bracket the bottom board of which is provided with an upright post clamping sheet, a clamping sheet bolt, a pair of position limiting torque springs symmetrically connected with the opening surface of the antenna in a distributed way, and steel wires. One bevel face of the bracket is provided with a polar axis angle regulating leading screw, the other sloping plate is fixedly provided with a motor and an internal sleeve, and the shaft of the motor is connected with a worm. In addition, an external sleeve is connected with the internal sleeve through a bearing, a star-shaped wheel inlaid at the outer wall of the external sleeve is connected with a star-shaped rod, and the external sleeve is provided with an upper cover clamping sheet which can be connected with an antenna tray. The spinner has simple structure, low cost, stable operation, and good wind resistance performance, and is suitable for matching with antennae with different types for application.
Description
The utility model is the satellite antenna drive unit.Be specially a kind of Antenna change direction device.
In order to use common antenna to receive the TV signal of the satellites transmits of different spatial, need to adopt antenna driving device to change the receive direction of antenna.Advanced is the U.S. hawk board polar axis antenna that U.S. PBI company produces at present, and it is made up of electric pushrod driver, dedicated antenna controller.Make the push rod of driver act on antenna by controller, make antenna center on the pole axis rotation, reach the purpose of selecting different satellite-signals.The shortcoming of this device is its complex structure, cost height, wind resistance power poor performance, and needs the configure dedicated DC power supply.
The purpose of this utility model be to provide a kind of simple in structure, cost is lower, wind resistance power performance is good, and easily and the electronic satellite antenna steering gear of the matching used polar mounts of existing antenna.
Adopt the steering gear of following proposal, it is simple in structure, cost is low, wind resistance is good, working stability and easily cooperate different antennas to use.
Accompanying drawing is this steering gear structural representation
Among the figure: 1-A-frame, 2-column card, 3-card spiral shell
Bolt, thick stick during 4-pole axis angle is regulated, 5-stop nut, 6-spacing
The moment spring, 7-interior cover, 8-overcoat, 9-motor, 10-scroll bar,
11-turbine, 12-protective cover, 13-bearing, 14-loam cake card
Sheet, 15-pressure bearing, 16-steel wire.
Below in conjunction with accompanying drawing this steering gear working condition is briefly explained:
When motor 9 passes through to rotate (forward or reverse), be linked as with motor shaft The scroll bar 10 of one rotates; Because turbine 11 is crosslinked with scroll bar 9, and outer Cover 8 is connected as a single entity with turbine 11, and overcoat 8 is again by bearing 13, pressure axis Hold 15 and connect with inner sleeve 7, thus overcoat 8 rotate take inner sleeve 7 as the axle center, logical Cross the loam cake card 14 that is fixed on the overcoat 8 and drive antenna change reception The orientation. 12 anti-dustproof effect that brush up against of protective cover.
Owing on the base plate of A-frame 1 column card 2 and card bolt 3 are set, guarantee whole steering gear and connect antenna to be fixed on the basal plane by it.
By adjusting stop nut 5, in adjust the bearing height that leading screw 4 is regulated at the pole axis angle in having, thereby it is consistent with the local latitude angle to reach the antenna polar axis angle.Owing to be fixed with a pair of spacing moment spring 6 on the base plate of A-frame 1, and the steel wire on it 16 is connected with antenna (receiving plane), so can play the effect that limits the antenna slewing area and reach enhancing motor thrust moment.
