Description

Technical Field

[0001] The invention relates to the field of antenna technology, and in particular to an inflatable self-supporting antenna mount. Background Art

[0002] Antennas used in certain places need to be filled with inert gas on the electromagnetic beam path within the antenna system to ensure the normal emission of the antenna electromagnetic beam. This requires the installation of an inflatable cover on the electromagnetic beam path inside the antenna to ensure that the inert gas on the electromagnetic beam path does not dissipate. At the same time, in order to realize the function of the antenna, the antenna mount must support the weight of the antenna surface, and at the same time ensure that the antenna surface rotates within a certain angle range in azimuth and pitch. This requires the antenna mount to have a certain strength and rigidity. In particular, when the antenna is installed on a mobile carrier, the overall weight of the antenna system will be limited. At this time, the antenna mount not only has to bear the weight of the antenna surface, but also needs to withstand various vibration shocks and wind loads brought about by the movement of the mobile carrier.

[0003] The antenna mount of a traditional antenna system generally requires two arm assemblies to support the antenna surface and rotate within a certain range of azimuth and elevation. If the inert gas on the electromagnetic beam path is to be prevented from dissipating, an additional rigid inflatable cover is required. This will increase the weight of the entire antenna system and is not conducive to installation and use on a mobile carrier.

[0004] When high-power electromagnetic waves are emitted, sparks will occur when they reach a critical state; in the event of sparks, black spots will be burned on the mechanical structural parts, making it difficult to emit electromagnetic waves. Summary of the invention

[0005] In view of this, the present invention provides an inflatable self-supporting antenna mount, which reduces the weight of the entire antenna system and is more convenient for installation on a mobile carrier.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] An inflatable self-supporting antenna mount, comprising an azimuth mechanism, an inflatable cover assembly and an elevation arm assembly;

[0008] The azimuth mechanism comprises an azimuth bearing 2, an azimuth turntable 4 and an azimuth driving device 3 located on an azimuth base 1; the azimuth bearing is fixedly arranged on the top of the azimuth base; the azimuth turntable is installed on the top of the azimuth bearing, and the two bearings are connected; the azimuth driving device is inverted on the azimuth turntable, and its driving end passes through the azimuth turntable and meshes with the outer edge teeth of the azimuth bearing;

[0009] The inflatable hood assembly includes a first inflatable hood 5, a pitch bearing 6, a second inflatable hood 7 and a pitch fan gear 8 located on the azimuth turntable 4; the pitch bearing connects the first inflatable hood and the second inflatable hood to achieve relative rotation of the two inflatable hoods; the pitch fan gear is installed at the other end of the second inflatable hood;

[0010] The pitch arm assembly includes a pitch arm 10 and a pitch drive device 9; the pitch arm is located on the upper surface of the azimuth turntable, and the pitch drive device is installed on the pitch arm, and its pinion is engaged with the pitch fan gear in the inflatable hood assembly to provide power for the second inflatable hood to rotate in pitch.

[0011] Furthermore, both the first inflatable hood and the second inflatable hood need to be filled with inert gas.

[0012] Furthermore, the antenna reflector is installed at a mounting position on the top of the second inflatable cover to achieve the pitch rotation of the antenna.

[0013] The beneficial effects of the above technical solution of the present invention are:

[0014] 1. The inflatable self-supporting antenna mount of the present invention is light in weight and is convenient for installation and use in a mobile carrier.

[0015] 2. Compared with the traditional antenna mount, the inflatable self-supporting antenna mount of the present invention uses one less elevation arm assembly, and the height of the other elevation arm assembly is greatly reduced, which reduces the weight of the entire antenna system and also reduces the price, making it more competitive.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] An inflatable self-supporting antenna mount comprises an azimuth mechanism, an inflatable cover assembly and an elevation arm assembly.

[0023] The azimuth mechanism comprises an azimuth bearing, an azimuth turntable and an azimuth driving device located on a base.

[0024] The inflatable hood assembly includes a first inflatable hood, a pitch bearing, a second inflatable hood and a pitch fan gear located on the azimuth turntable, the pitch bearing connects the first inflatable hood and the second inflatable hood to achieve relative rotation of the two inflatable hoods. The pitch fan gear is installed at the other end of the second inflatable hood.

[0025] The pitch arm assembly comprises a pitch arm and a pitch driving device, wherein the pitch driving device is mounted on the pitch arm, and a pinion gear of the pitch driving device is meshed with a pitch sector gear in the inflatable hood assembly to provide power for pitch rotation for the second inflatable hood.

[0026] The rigid inflatable cover assembly needs to be filled with inert gas of a certain pressure, which requires that each of the first inflatable cover, the pitch bearing, the second inflatable cover and the pitch sector gear is airtight and leak-proof and can withstand a certain gas pressure. At the same time, the inflatable cover assembly after the parts are assembled together is also required to be airtight and leak-proof and can withstand a certain gas pressure. The connection between the inflatable cover assembly and other structural parts needs to be equipped with a sealing ring to ensure that the inert gas filled in the entire antenna system does not leak.

[0027] The first inflatable hood in the rigid inflatable hood assembly also functions as a replacement for a pitch arm assembly, that is, the pitch arm assembly is no longer needed as a support, reducing the weight of the antenna system. At the same time, the height of the other pitch arm assembly is much lower than the height of the pitch axis, further reducing the weight of the antenna system. When transmitting high-power electromagnetic waves, in order to ensure that the electromagnetic wave channel is unobstructed, an inert gas is filled in the inflatable hood and used as a support to replace the existing support arm.

[0028] The antenna surface is fixed on the top of the second inflatable cover by bolts, the second inflatable cover is connected to the first inflatable cover by a pitch bearing, the first inflatable cover is fixed on the azimuth turntable by bolts, and the azimuth turntable is connected to the mounting base by bolts through the azimuth bearing. That is, the two sets of pitch arms of the traditional antenna system are not needed, but the structural support of the antenna surface is achieved through the inflatable cover assembly.

[0029] The pitch arm assembly is equipped with a pitch drive device, which provides a power source for pitch rotation. The second inflatable hood in the inflatable hood assembly is equipped with a pitch fan gear at one end, and the other end is connected to the first inflatable hood through a pitch bearing by bolts. The pitch bearing realizes the relative rotation of the second inflatable hood relative to the first inflatable hood. The small gear of the pitch drive device meshes and rotates with the pitch fan gear, so as to realize the continuous pitch rotation of the antenna surface within a certain angle range. The first inflatable hood is fixed to the azimuth turntable as a whole by bolts, the azimuth turntable is connected to the inner ring of the azimuth bearing by bolts, and the outer ring of the azimuth bearing is connected to the mounting base by bolts. An azimuth drive device is installed on the azimuth turntable, which provides a power source for azimuth rotation. The small gear of the azimuth drive device meshes with the large gear of the outer ring of the azimuth bearing to realize the continuous azimuth rotation of the antenna mount. Through the continuous rotation of azimuth and pitch, the continuous clockwise and counterclockwise rotation of the antenna surface in the azimuth and pitch directions within a certain angle range is realized.
