Rolling and vibration reduction and battery position adjustment system for surface unmanned boat manufacturing method

1. The utility model relates to the technical field of ship equipment, specifically a system for anti-rolling and vibration reduction and battery position adjustment of a surface unmanned boat.

Background technique:

2. Surface unmanned boat, or surface robot, is an unmanned surface vessel. The general surface unmanned craft is small in size, shallow in draft, usually has no ballast tank, and it is difficult to adjust the floating state. During the design of ordinary surface unmanned boats, the position of the center of gravity is estimated based on the installed equipment; and the center of gravity is adjusted by changing the position of some heavy equipment along the length (longitudinal) of the ship, thereby changing the floating state. However, this method cannot give feedback to the external environment and its own changes. Therefore, this method only has a better effect under the conditions of low weight of external equipment and stable sailing conditions. When the weight of the externally installed equipment changes and the navigation conditions of the unmanned boat are complicated, the center of gravity and the position of the buoyancy center will change uncontrollably, which will cause the navigation state to deteriorate, which will affect the speed, stability and maneuverability of the unmanned boat. In addition, unmanned boats are often equipped with complex sensors and control systems. These devices contain high-precision electronic components, some of which require harsh working environments. Large swings and vibrations will cause the performance of these devices to decline, fail to work properly, or even be damaged. Therefore, the anti-rolling and damping of important components are very important in unmanned boats.

3. At present, there have been studies on the floating state of unmanned boats in China, mainly focusing on the stability of unmanned boats, and there are few applications for automatically adjusting the floating state. There is a new utility model "unmanned boat self-righting device" that can be used for floating adjustment, but this device mainly addresses the problems of large inclination and rollover, and the device has a large structure and is not easy to install. Foreign research on the automatic adjustment of the floating state is mainly concentrated in the field of underwater robots, and there is not much research on the automatic adjustment of the floating state of the surface unmanned boat. There are few domestic and foreign researches on the vibration reduction of unmanned boats. Shanghai Jiaotong University has published a study on the active control vibration reduction of unmanned boats with nonlinear negative stiffness.

4. Batteries are the main source of energy for unmanned boats. Under normal circumstances, the higher the endurance requirements of unmanned boats, the heavier the battery weight; usually, its weight can reach 30 percent of the total weight of the unmanned boat. Therefore, adjusting the battery position is an important method to adjust the floating state of the unmanned boat. In addition, anti-rolling of the battery can improve the working environment of the battery, and increase the stability and overall structural strength of the unmanned boat.

5. The present invention is to develop an integrated mechanical structure and automatic control system. Its purpose is to stabilize the battery, control elements and sensors, and adjust the position of the battery in real time to control the unmanned boat floating. state.
