[0028] The relay buoy system in the related art has a large swing angle in a windy and wave environment, and the large swing of the relay buoy system will affect the signal transmission accuracy of the air-sea cross-medium communication. In addition, most of the relay buoy systems in the related art are powered by solar energy, and the relay buoy system needs to be equipped with a communication system and indicator light beacon, satellite positioning system and other devices, so it requires a large energy consumption. Due to the limited size of the relay buoy system, it is impossible to increase the efficiency of solar power generation by installing solar panels on land over a large area. In addition, adding solar panels may also increase the wind resistance area of ​​the relay buoy system, which is not conducive to the survival performance of the ocean buoy, and also affects the stability and difficulty of the buoy. Therefore, how to increase the endurance and service life of the offshore relay buoy system by comprehensive use of offshore energy, and how to achieve the anti-current stabilization performance of the offshore relay buoy system to increase the transmission accuracy of the air-sea communication system are problems that need to be solved in this field.

[0047] In some embodiments, a lifting ear 1 - 2 is provided on the top cover 1 - 1 .

[0050] The following describes the working steps for implementing the above embodiment:

[0051] When in use, the relay buoy system provided by the present invention is first assembled, and then hoisted to the sea surface through the lifting lugs 1-2, and floated on the water surface by the buoyancy generated by the main buoy 1, and the solar panels 4 and other components are symmetrically arranged to ensure that the overall center of gravity of the device is centered. After hoisting to the target position, the bottom anchor chain 7 and cement weights are dropped to the seabed to complete the mooring deployment of the relay buoy system.

[0052] During operation, the photovoltaic power generation device, the wind power generation device 2, the tidal power generation device 8 and the diesel generator 1-10 provide complementary energy to realize the all-weather power capture of the relay buoy system, ensuring that the relay buoy system can work normally even in extremely harsh environments. At the same time, the power generated in the power generation equipment is stored through the power storage device 1-9, and stably discharged to the corresponding equipment. By setting a heave plate 9 at the bottom of the relay buoy system, the relay buoy system is given additional mass and viscous damping, the heave natural period is increased, the heave damping is increased, and the heave response of the platform is reduced. At the same time, by setting a six-degree-of-freedom parallel stabilizing platform 6, the active movement of the driving element (electric cylinder 6-2) is used to offset the swing of the relay buoy system at sea to achieve the stabilization function.
