Satellite positioning antenna device

Abstract

The invention belongs to the technical field of antenna devices, and particularly relates to a satellite positioning antenna device. The satellite positioning antenna device comprises a supporting block, a first threaded rod, a base, a leveling bubble, a first connecting column, a center plate, an outer frame plate, a supporting column, a vertical column, a second threaded rod, an inclined block,a nut, a circular concave block, a paraboloid, a feed source, a fixed frame, a second connecting column, a disc, a bearing, a sun wheel, planetary gears, a motor, a connecting block, a fixed plate anda connecting plate. The motor is installed at the bottom of the disc to adjust the azimuth angle, and the motor rotates to drive the sun wheel at the tail end of the output shaft to rotate; then thefour planetary gears are used for decelerating the sun wheel, and then the sun wheel is transmitted to the disc, so that the disc can rotate slowly, and the paraboloid can rotate in the horizontal direction; and the leveling bubble is installed on the base of the satellite antenna, and the distance between the supporting block and the base is adjusted by rotating the first threaded rod to compensate the uneven surface of the ground; and the water drops in the leveling bubble are adjusted to the middle position.

Description

technical field [0001] The invention belongs to the technical field of antenna devices, in particular to a satellite positioning antenna device. Background technique [0002] The satellite antenna is often called the cauldron, which is a metal parabola, which is responsible for reflecting the satellite signal to the feed source and high frequency head at the focal point; the function of the satellite antenna is to collect the weak signal transmitted by the satellite and remove it as much as possible. Noise; most antennas are usually parabolic, and some multi-focus antennas are composed of spherical and parabolic. The satellite signal is concentrated to its focus after being reflected by the parabolic antenna. [0003] Satellite antennas are widely used in daily life. When adjusting the azimuth angle, it is necessary to use precision instruments to measure the angle, and the antenna needs to be manually moved during the adjustment process. This not only makes the adjustment p...

Problems solved by technology

[0006] The object of the present invention is to provide a satellite positioning antenna device in order to solve the above problems, by installing a motor at the bottom of the disc to adjust the azimuth angle, the motor rotates to drive the sun gear at the end of its output shaft to rotate, and then four A planetary gear decelerates the sun gear, and then transmits it to the disc, so that the disc rotates slowly, realizing the rotation of the parabola in the horizontal direction, and judging the correct position of its angle through the display of the satellite receiving equipment, achieving automatic The purpose of adjustment is to solve the problem of using instruments to measure during the adjustment process, and to avoid manual adjustment. A level bubble is installed on the base of the satellite antenna, and the distance between the support block and the base is adjusted by rotating the first threaded rod. Compensate for the unevenness of the ground. When the water droplets in the vial move to the middle position, the satellite antenna has been adjusted to the horizontal position at this time, avoiding the problem of repeated adjustments caused by the unevenness of the ground.
