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

Embodiment Construction

[0016] see figure 1 , 2 , 3, the surface unmanned boat includes the main hull 1, the design waterline length of the main hull 1 is L, and the design waterline width is B.

[0017] There are two fully enclosed pillars 2 on the deck 11 of the main hull 1, which are made of composite light materials such as glass fiber reinforced plastics or aluminum alloys, and all the remaining spaces in the interior are filled with light materials. Two pillars 2 are vertically arranged above the deck 11, relative to the main hull 1, the two pillars 2 are symmetrical in the left and right width direction, and their center is located at the midship part of the main hull 1 or at the front of the midship (1 / 8-1 / 6) At position L, the bottom and sides of the two pillars 2 are connected smoothly and seamlessly to the deck 11, and the stress concentration at the connection part should be avoided during connection. The contour lines of the front and rear edges of the two pillars 2 from bottom to top...

Abstract

The invention discloses a crosswise double-column supporting type superstructure of an unmanned surface vehicle. Two fully-closed struts are symmetrically arranged on a deck of a main vehicle body in the left-and-right width direction, the center of the two struts is located on the midship portion or at the position which is located in front of the midship by (1 / 8-1 / 6) L, L is the designed waterline length of the main vehicle body, the contour line between the front-most edge of the each strut and the rear-most edge of the strut from top to bottom is a quadratic parabola, and the area of the horizontal cross sections of the two struts decreases gradually from top to bottom. A first-layer perception platform and a second-layer perception platform located over the first perception platform are arranged at the top of each strut, and the first-layer perception platforms are connected with the second-layer perception platforms through connecting columns to form a composite framework of the perception platforms. Thus, perception equipment can be better arranged, the longitudinal stability of sailing of the vehicle body can be enhanced, and the sailing performance and the self-righting performance of the unmanned surface vehicle during wave sailing are enhanced.

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 ...
