Experimental platform for wave-driven unmanned surface robot

Abstract

The invention relates to an experimental platform for a wave-driven unmanned surface robot. The platform comprises a floating body and an underwater carrier, which are connected by a mooring cable. The floating body is provided with a servo motor, a speed reducer and a reel. The underwater carrier portion is provided with webbed wings and a fixing mechanism for a webbed wing rotating shaft. The servo motor on the floating body drives the speed reducer and the reel to rotate after being powered on, and the mooring cable around the reel is connected with the underwater carrier, so that the amplitude and period of wave motions can be simulated by adjusting the forward and reverse rotation and the motion period of the motor on the floating body. The platform overcomes the randomness of sea wave motions and the complex conditions of sea trials, and can be carried out in a pool of a laboratory. The platform can simulate the wave motions under different sea conditions by on-line modifying motor motion parameters through a PLC controller to carry out quantitative analysis, which provides great convenience. Therefore, the platform has the advantage of simple operation, safety, reliability,adjustability, convenient use, high efficiency, low cost and the like.

Description

technical field [0001] The invention relates to the field of underwater robot engineering, in particular to an experimental platform for a wave-driven unmanned surface robot. Background technique [0002] As an important marine operation and observation platform, underwater robots have been widely used in marine scientific research, marine resource development, marine atmospheric physics, and marine ecology. However, the ocean is a vast water area. It is not easy to carry out the above tasks. The main problem is that due to the constraints of the size of the underwater robot itself, the energy it carries is very limited, and its battery life is greatly limited by the energy. All countries are striving to make breakthroughs in the energy issues of underwater robots. [0003] On the one hand, countries are optimizing and improving the energy utilization rate of the system. On the other hand, they are researching and developing some new energy sources, such as temperature diff...

Problems solved by technology

However, the application of these wave energy conversion devices in the field of underwater robots has certain difficulties. On the one hand, the volume of the conversion devices is large and it is not easy to assemble. On the other hand, even if they can be assembled, the inertia of the underwater robot will make the wave energy conversion devices The efficiency of the underwater robot is very low, because the wave first needs to excite the shell of the underwater robot to make the underwater robot move, and then the underwater robot transmits the motion to the internal wave energy conversion device
