Problems solved by technology

Therefore, in addition to some large-scale antennas that have been built, some equipment that has not been built may also be built on the seismic zone, which poses a risk of earthquake damage
If an earthquake occurs, the large antenna with huge height, weight and volume will directly bear the impact and vibration brought by the seismic wave, and it is very easy to deform, damage and collapse, and the consequences will be disastrous

Abstract

The invention discloses a large antenna with a combined shock isolation and absorption structure, and belongs to the technical field of antennas. The structure comprises a reflector, a seat frame, a cable, a cable power device, an upper-layer damping structure, a middle-layer damping structure and a lower-layer damping structure. The antenna is stable in state and does not affect accurate operation of the antenna when an earthquake does not occur, can effectively play a role in shock isolation and shock absorption in the earthquake occurrence process, and has the advantages of light weight, low cost, easiness in installation and replacement and the like.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a large-scale antenna with a combined shock-isolation and shock-absorbing structure. Background technique [0002] With the rapid development of society's scientific and technological capabilities, radio astronomy has entered the era of high-sensitivity large samples, and large radio telescope antennas have played an important role in it. Human beings' desire for deeper and more urgent exploration of space has further driven the demand for the construction of large-scale radio telescope antennas, especially large-scale fully movable reflector telescope antennas with a diameter of about 50 meters or even more than 100 meters. [0003] Usually, the main structure of such a large antenna mainly includes two parts, that is, a mount part and a reflector part. Among them, the reflector part is used as the functional part of the antenna. The reflector carries a huge reflective surfac...
