A self-righting method for an unmanned ship

Abstract

The invention discloses an unmanned ship with a self-straightening function and a method. The unmanned ship comprises an unmanned ship body. The unmanned ship body is of a fully-sealed structure. Whenthe unmanned ship body is in a positive floating state, the gravity center is located under the buoyancy center, and the unmanned ship becomes a tumbler in water. The unmanned ship comprises an automatic straightening calculation control module, an inclination angle measurement device and a straightening propelling device in the water depth direction, the straightening propelling device is drivenby a steering engine, inclination angle rotation at a certain angle is achieved, so that the water spraying propelling direction is changed, and the automatic straightening calculation control moduleis connected with the straightening propelling device in the water depth direction and the inclination angle measurement device. The unmanned ship has the beneficial effects that a water spraying propelling device is connected through the automatic straightening calculation control module, so that the water spraying flow, the water spraying direction and the water spraying duration of the water spraying propelling device are controlled through the automatic straightening calculation control module, and safety is provided for following navigation.

Description

technical field [0001] The invention relates to the field of design and application safety of an unmanned ship, in particular to a self-righting technology for an unmanned ship after buckling and overturning. Background technique [0002] As people's awareness of the research and protection of oceans, lakes, reservoirs and other waters increases, people begin to investigate and detect them. When the investigation and detection personnel arrive in special waters, they use the detection equipment and sensing equipment ADCP to carry out detection, that is, use manned ships to conduct investigations, but this is usually only conducted in a specific period of time, because it requires a large number of participants, so , usually the labor and economic costs of this kind of investigation are relatively high, and it is usually not possible to maintain round-the-clock, uninterrupted investigation and detection, and usually only occasional investigations can be conducted; [0003] A...

[0006] On the other hand, there are also ships that use water jets to propel in the opposite direction, but they do not consider the size of the ship's inclination, ship's load capacity, center of gravity, center of gravity, and sea conditions, that is, the righting moment provided is always the same , not to mention the generation time of the righting moment, which is more of a theoretical conceptual model, but in actual use, the magnitude and duration of the force are not considered, which will inevitably lead to the fact that the propulsion and righting moment cannot really make the ship resist Capsizing means that the ship tilts in the opposite direction, or even capsizes, and even if it does not capsize, it will cause the ship to shake continuously. Therefore, this vague conceptual model obviously does not consider the actual situation and cannot be used to right the ship;
