Description

Technical Field

[0001] The invention belongs to the field of hull structure engineering and relates to a ground-type antenna ball cover base structure. Background Art

[0002] In recent years, with the continuous development of measurement and control communication technology, people's demand for measurement and control distance and measurement accuracy has been growing, and the scale of measurement and control antennas has tended to be larger and larger. As the Yuanwang series of ships are mainly used to measure flight data related to aerospace equipment, there are more and more various measurement and control communication antennas on board, and their scale is also getting larger and larger. The corresponding antenna dome diameter has also increased from a few meters to more than ten meters or even dozens of meters. As the dome size increases, the load it receives also increases. The original fiberglass dome can no longer withstand such a large load alone. The current common practice is to use a combination of metal trusses and fiberglass, which also greatly increases the weight of the antenna dome.

[0003] In the past, the antenna dome base and the cylinder base were usually designed in an integrated manner. A platform connected to the antenna cylinder was built near the height of the antenna dome base, and the dome base was located on the platform. This integrated design of the antenna dome base and the cylinder base will inevitably cause the antenna dome to deform the cylinder base. When the dome is enlarged and heavier to a certain extent, this effect cannot be ignored and may even interfere with the antenna operation.

[0004] On the other hand, some scattered small cabins, such as small fan rooms, are often needed on the open deck. At the same time, the antenna equipment itself may also have some working cabins or spare rooms that need to be arranged around the antenna. These cabins are scattered everywhere, affecting the appearance of the open deck. Summary of the invention

[0005] At least one technical problem among the above-mentioned defects to be solved by the present invention is to provide a ground-type antenna ball cover base structure, which realizes the separate design of the antenna ball cover base and the antenna cylinder base on the basis of ensuring the utilization rate of the deck space, reduces the influence of the antenna ball cover base on the antenna cylinder base, and reduces the probability of interference with the antenna operation.
