Abstract

The invention discloses a single-pillar superstructure of an unmanned water surface boat. A fully enclosed pillar is arranged on the deck of the main hull. The bottom of the pillar is smoothly transitioned and fixedly connected to the deck. Quadratic parabola, and the area of ​​the horizontal cross-section gradually decreases from bottom to top, the height of the pillar is equal to 1 / 2 to 11 / 8 of the design waterline length of the main hull, and the front and rear length of the lower part of the pillar is equal to the design waterline length of the main hull 1 / 4 to 3 / 4 of the pillars, the top of the pillars are set up three layers of sensing platforms from bottom to top, and each layer of sensing platforms is connected by connecting columns; more platforms are provided for the arrangement of equipment, and the main hull completely forms a Overall, the structural strength of the hull is increased, so that the surface unmanned boat has good self-righting performance.

Description

technical field

[0001] The invention relates to a surface unmanned boat, which is used for surface and underwater dynamic monitoring, water surface patrol and various operations, in particular to a single-column superstructure structure of the surface unmanned boat. Background technique

[0002] The type of unmanned boat is mostly monohull type. Due to its small displacement and size, it is particularly sensitive to the external environment such as wind, waves and currents, and it is difficult to maintain good motion stability during high-speed sailing, especially the swaying motion. The stability, dynamic stability and anti-overturning performance are poor, the sailing economy is poor, and the probability of normal operation under high sea conditions is low. This type of boat-type structure, especially the superstructure structure, does not scientifically take into account the requirements of dynamic stability, anti-overturning, perception efficiency of sensing equipment an...

Embodiment Construction

[0018] see figure 1 , 2 As shown, the surface unmanned boat includes a main hull 1, and the design waterline length of the main hull 1 is L.

[0019] A strut 2 is arranged on the deck 11 of the main hull 1. The strut 2 is a fully enclosed structure. Relative to the main hull 1, the centroid of the strut 2 can be set aft, centered, and forward. The bottom of the strut 2 and the deck 11 of the main hull 1 are smoothly transitioned and fixedly connected to form a fully enclosed hull, and it is necessary to avoid stress concentration in the connecting part of the two. The pillar 2 is made of non-metallic composite materials such as carbon fiber composite materials or lightweight materials such as aluminum alloys. The contour lines of the front and rear edges of the pillar 2 are quadratic parabola from bottom to top, and the area of ​​the horizontal cross-section of the pillar 2 gradually decreases from bottom to top, so that the center of gravity of the pillar 2 is the lowest, w...
