Description

Alignment adjustment device and satellite antenna

technical field

The invention relates to an alignment adjustment device and a satellite antenna, in particular to an alignment adjustment device and a satellite antenna with omnidirectional and high-precision adjustment functions.

Background technique

Because satellite communication has the characteristics of long communication distance and extremely wide coverage, satellite communication is widely used in many fields, such as radio and television, communication and so on. Therefore, even in the desolate desert or the vast sea, as long as the receiving antenna is set up, the satellite signal can be received. Please refer to FIG. 1 , which is a schematic diagram of a conventional satellite antenna system 10 . The satellite antenna system 10 includes a satellite dish 102 , a satellite wave collector (Low Noise Block Down-converter with Integrated Feed, LNBF) 104 , and a support arm 106 . In the satellite antenna system 10 , the satellite signal is usually reflected to the satellite collector 104 by the satellite dish 102 which is in the shape of a parabola. After the high-frequency satellite signal is extracted by the satellite collector 104 and down-converted into an intermediate-frequency satellite signal, the satellite signal is transmitted to the back-end satellite receiver through the coaxial cable for processing.

At present, for the installation of the components of the satellite antenna system 10 , the alignment adjustment is mainly performed manually. For example, the satellite wave collector 104 is usually installed on the support arm 106 to receive satellite signals reflected by the satellite dish 102 . Generally speaking, in the multi-satellite application, there will be multiple satellite collectors 104 fixedly installed on the support arm 106 at the same time. When the oscilloscope 104 is used, the most complete satellite signal is usually received. However, when the satellite wave collector 104 is fixedly installed on the support arm 106, it is often impossible to flexibly perform more precise alignment adjustments. Since the antenna has a very sensitive directivity, if the satellite wave collector 104 cannot be adjusted to the optimum The receiving position will seriously affect the receiving performance. Especially when it is applied to a multi-satellite situation, if the relative position between each satellite wave collector 104 and satellite dish 102 cannot be flexibly adjusted, each satellite wave collector 104 will not be able to realize the most complete signal acquisition function , thereby affecting the receiving performance of the overall satellite antenna system 10 .

Therefore, it is necessary to provide an alignment adjustment device and a satellite antenna with omnidirectional and high-precision adjustment functions.

It should be noted that the present invention can be applied to a satellite antenna system with one or more satellite wave collectors. The following description takes a satellite antenna system with two satellite wave collectors as an example, but is not limited thereto. . As shown in FIG. 2 , the satellite antenna system 20 includes a satellite dish 22 , a satellite wave collector 24 , a support arm 26 and an alignment adjustment device 200 . Wherein, the satellite dish 22 has a focus axis F. As shown in FIG. The alignment adjustment device 200 is disposed on the support arm 26 . The satellite collector 24 is disposed on the alignment adjusting device 200 to receive satellite signals reflected by the satellite dish 22 . Therefore, the receiving position of the satellite collector 24 relative to the satellite dish 22 can be precisely adjusted by the alignment adjusting device 200 of the present invention.

The alignment adjusting device 200 includes a fixing base 220 and an axis rotating bracket 240 . The fixing base 220 is fixed on the supporting arm 26 . The fixing base 220 includes a first pivot portion 222 , a second pivot portion 224 and a fixing component 226 . Each of the first pivotal portion 222 and the second pivotal portion 224 has a through hole. The fixing component 226 includes a bolt 2262 and a nut 2264 , wherein the bolt 2262 and the nut 2264 are corresponding screwed parts. The fixing component 226 is used to pivotally connect the fixing base 220 to the supporting arm 26 . For example, the fixing base 220 is pivotally connected to the support arm 26 through the bolt 2262 passing through the second pivot portion 224 and a third pivot portion (not shown in FIG. 2 to FIG. 4 ) of the support arm 26 . The axis rotation bracket 240 is connected to the fixed seat 220 in a manner that can rotate along the axis F of the focus point. The axis rotation bracket 240 includes a bracket base 242 , an arc groove 244 and a first positioning component 246 . As shown in FIG. 3 , the satellite wave collector 24 is fixed on the bracket body 242 . The arc groove 244 is disposed on the support body 242 , and a center of the arc groove 244 is located on the axis F of the focal point. The first positioning component 246 can pass through the first pivot portion 222 and the arc groove 244 to pivotally connect the axis rotation bracket 240 to the fixed base 220 , and can position the fixed base 220 and the axis rotation bracket 240 along the arc groove 244 relative position. In other words, the first positioning component 246 can slide along the arc groove 244 to adjust the relative position of the axis rotation bracket 240 and the fixing base 220 , so that when the alignment adjustment is performed, the first positioning component 246 can slide along the arc groove. 244 slides to change the fixed position, and the axis rotation bracket 240 will correspondingly rotate and move based on the center of the arc groove 244 . In this case, the axis rotation bracket 240 rotates along the focus axis F to perform rotation alignment adjustment. Therefore, when adjusting the relative position between the satellite wave collector 24 and the satellite dish 22, through the design of the alignment adjustment device 200, the satellite wave collector 24 can be rotated and moved along the axis F of the focal point to adjust the most Suitable signal receiving location.
