Description
Technical Field
The utility model relates to antenna technical field, in particular to large-scale antenna with rubber shock insulation structure.
Background
With the great development of the social science and technology ability, the radio astronomy has entered into a large sample age with high sensitivity, and a large radio telescope antenna plays an important role therein. The demand of human beings on increasingly deep and urgent exploration in space further drives the construction requirement of large radio telescope antennas, in particular to large full-movable reflector type telescope antennas with the caliber of about fifty meters or even more than one hundred meters.
Typically, the main structure of such large antennas comprises mainly two parts, namely a chassis part and a reflector part. Wherein the reflector part functions as a functional part of the antenna. The reflector bears a large-area reflecting surface for receiving electromagnetic wave signals collected in the deep space, not only has a more complex structural form, but also can be provided with a plurality of expensive and precise devices, which is the main contradiction of the antenna. The seat frame belongs to a steel structure support subordinate part with a simpler structure form and has the function of supporting and driving the reflector part to perform pitching and azimuth motion.
For decades, humans have built more and more large telescope antennas but their basic form is rarely innovative. Such as 65 meters astronomical telescope built in Shanghai, 66 meters deep space exploration antenna built in Jia Musi, 70 caliber antenna built in Tianjin, and 120 meters antenna in Yunnan. Such conventional large antenna structures are characterized by high height, large weight and volume. The reflector portion is connected to the mount only by two pitch axis seating positions. The form hardly considers the damage of earthquake to the antenna structure from the perspective of structural design, and no active shock absorption measure is taken. In addition, the construction and site selection of the large telescope antenna mainly pursues a pure electromagnetic environment far away from modern human life and the requirement of large span of networking observation among a plurality of large antennas, but mainly considers the influence of earthquake. Therefore, besides the large-scale built antennas, some devices which are not built can be built on the seismic belt, and the potential hazard of earthquake ring breaking exists. If once earthquake happens, the large antenna with huge height, weight and volume can directly bear the impact and vibration brought by earthquake waves, and deformation, damage and collapse are easy to happen, and the consequences are not imaginable.
In recent years, domestic seismic isolation and absorption technologies for dealing with earthquake disaster damage are developed greatly and are widely popularized and applied to many high-rise buildings and large-scale equipment. Among them, the vibration isolation rubber support is more applied. The support mainly comprises a sandwich structure formed by tightly combining a steel plate and rubber, and not only has very high vertical bearing capacity, but also has larger horizontal deformation capacity and repeated load fatigue resistance. In practical engineering application, a flexible shock insulation layer is added between an upper layer structure and a foundation, and a rubber shock insulation support is installed to play a role in flexible connection with the foundation. When an earthquake occurs, most of energy generated by the earthquake is absorbed by the flexible seismic isolation layer in the process of transmitting to the upper structure, and only a small part of energy is transmitted to the upper structure. It is understood that by such a technique, it is possible to offset about 80% of the seismic destruction energy, thereby effectively reducing the seismic destruction effect of the superstructure and improving the safety of the superstructure.
Therefore, by combining the respective characteristics of the large antenna structure and the rubber shock-isolation support, a main body structure of the large antenna with the active shock-isolation and shock-absorption functions needs to be developed. The novel structural form has the advantages that the state is stable when no earthquake occurs, the accurate operation of the antenna is not influenced, and the shock insulation and absorption effects can be effectively realized in the earthquake occurrence process.

The following is a specific example:
as shown in fig. 1 and 2, the present embodiment mainly includes a reflector 1, a pitch shaft seat 2, an upper rubber vibration isolation structure 3, a pitch seat frame 4, a lower rubber vibration isolation structure 5, an azimuth turntable 6, a foundation 7, and the like.
Wherein, the reflector 1 is connected with two pitching shaft seats 2. The bottoms of the two pitching shaft seats are respectively connected with two upper rubber shock insulation structures 3.
