Transverse twin-pillar-supported superstructure for unmanned surface vehicles

Abstract

The invention discloses a horizontal double-column support superstructure of an unmanned water surface boat. Two fully enclosed columns are symmetrically arranged on the deck of the main hull in the left and right width directions, and the centers of the two columns are located at the midship or At the position L in front of the midship (1 / 8-1 / 6), L is the design waterline length of the main hull, the bottom-to-top contour of the front and rear edges of the two pillars is a quadratic parabola, and the two pillars The area of ​​the horizontal cross-section gradually decreases from bottom to top; the top of each pillar is arranged with the first layer of perception platform and the second layer of perception platform directly above the first layer of perception platform, the first layer of perception platform and the second layer of perception platform The sensing platforms are connected by connecting columns to form a composite frame of the sensing platform; the sensing equipment can be better arranged, the longitudinal stability of the hull navigation can be improved, and the navigation performance and self-righting of the surface unmanned vehicle in wave navigation can be improved.

Description

technical field [0001] The invention relates to a water surface unmanned boat, which is used for water surface and underwater dynamic monitoring, water surface patrol and various operations, in particular to the horizontal double-column support superstructure structure of the water surface unmanned boat. Background technique [0002] Most of the unmanned boats are single-hull boats. Due to their small displacement and scale, they are particularly sensitive to external wind, waves and currents. It is difficult to maintain good motion stability when sailing at high speed, especially swaying motions. performance, dynamic stability and anti-overturning performance, the navigation economy is poor, and the probability of normal operation under high sea conditions is low. This type of boat structure, especially the superstructure, does not scientifically take into account dynamic stability, anti-overturning performance, sensing efficiency of sensing equipment and other performance ...

Problems solved by technology

[0002] Most of the unmanned boats are single-hull boats. Due to their small displacement and scale, they are particularly sensitive to external wind, waves and currents. It is difficult to maintain good motion stability when sailing at high speed, especially swaying motions. Performance, dynamic stability and anti-overturning performance, poor navigation economy, low probability of normal operation under high sea conditions

This type of boat structure, especially the superstructure, does not scientifically take into account dynamic stability, anti-overturning performance, sensing efficiency of sensing equipment and other performance requirements, but only builds a simple superstructure when needed. The superstructure structure is not closed, generally there is only one layer of sensing platform, which can not protect the sensing equipment well, but also makes the stability worse, thus reducing the overall navigation performance of the ship
