Abstract
Description
Technical Field
[0001] This utility model relates to the field of shipbuilding and marine engineering technology, specifically to a lightweight radar mast device. Background Technology
[0002] Radar masts are essential outfitting equipment for ships navigating at sea, playing a supporting role in normal navigation and emergency collision avoidance, and are widely used on ships. Traditional radar masts mostly adopt a streamlined steel plate design, are relatively heavy, have a tall and bulky appearance, and are expensive. They are also usually located on the ship's bridge deck or other high positions, which is not conducive to the weight center of gravity control of the ship's superstructure.
[0003] In practical applications, if the overall height of the radar mast is higher than the height of the ship's superstructure, it will not only greatly increase the weight of the empty ship, but also make the ship's overall center of gravity higher, and the overall shape of the ship will not be aesthetically pleasing. Therefore, traditional radar masts are not suitable for small and medium-sized ships that have strict control over the weight of the empty ship and the height of the center of gravity. In addition, the radar base and the lighting mast of the traditional radar mast are arranged separately, which not only leads to redundancy in the overall structure, but also makes daily maintenance inconvenient. Furthermore, the arrangement of the lighting on the traditional radar mast must meet the lateral spacing requirements of maritime regulations (such as 2m), which limits the flexibility of the design.
