Description

technical field [0001] The invention relates to technical fields such as communication, measurement and control, and radio astronomy, and in particular to a high-precision continuous adjustment device for a reflective antenna panel and a manufacturing method thereof. Background technique [0002] Reflector antennas are widely used in the fields of communication, measurement and control, and radio astronomy because of their high gain, low sidelobe, and strong designability. For large and medium-sized reflector antennas, due to the limitation of processing and manufacturing capabilities and transportation directions, the reflector should be divided into several antenna panels. During installation, these antenna panels should be combined to form a complete reflector. . [0003] For reflector antennas working in high-frequency bands (such as Ku-band), the surface accuracy is generally better than 0.5mm (rms), and the surface accuracy is generally composed of a single panel ac...

AI Technical Summary

Problems solved by technology

In the above three patents, the connection between the panel and the adjustment rod or the connection between the adjustment rod and the support point of the back frame are all in the form of plane contact. During the adjustment process of the panel, there will inevitably be a rotational movement between the adjustment rod and the panel. The planar connection between the two limits the degree of freedom of rotation, which will generate internal stress between the panel and the adjustment rod. When the internal stress is large, the panel will be deformed, thereby reducing the accuracy of the panel.

[0006] (2) Does not involve translation adjustment or how to achieve translation adjustment

The adjustment of the antenna panel involves translation adjustment and rotation adjustment. The above three patents only involve the axial adjustment of the panel, and do not involve the translation adjustment method, or the translation adjustment and the axial direction of a single panel cannot be independent of each other. Therefore, the three solutions Affected the adjustment accuracy of the panel

[0007] (3) The panel is in a state of internal stress for a long time, resulting in a decrease in accuracy

The above two patents can realize the axial continuous adjustment of the panel by means of threads, but for the movement adjustment in the horizontal plane of the panel, there is no corresponding continuous adjustment method

[0010] (2) When the antenna panel is in different attitudes, it needs to overcome the gravity adjustment, which is difficult to operate

As we all know, the reflector antenna is in the form of a parabola. When a single panel is at different positions on the reflector, its attitude is different. It is very large. When moving and adjusting a panel with a large slope, it is necessary to overcome the self-weight of the panel. During the adjustment process, slippage is prone to occur, especially when working at high altitudes, which will bring great difficulties to the operator and even bring come dangerous

[0011] (3) The adjustment efficiency is low, and it is easy to cause the adjustment position to not converge

For devices without continuous movement and adjustment, it is completely dependent on manual experience. When one direction is adjusted, it will affect the adjusted direction, resulting in a vicious circle where the panel adjustment position does not converge
