The working principle of the invention is as follows:
jellyfish is transparent umbrella-shaped, and moves in a mode of extruding the inner cavity to spray water by contracting the umbrella-shaped shell.

A more detailed description follows:
the buoyancy of the water surface buoy is larger, the water surface buoy floats on the water surface and can move up and down along with waves, when the water surface buoy moves up along with waves, the bionic body can move up along with the water surface buoy, six swinging plates in the embodiment can swing downwards around the hinge shaft like the shrinkage of the umbrella cover due to the action of water resistance, the swinging plate supporting rods are driven to push the follow-up base plates to move downwards, the follow-up base plates push the piston push rods, the piston push rods drive the pistons to move downwards, and then the water injection action to the energy accumulator is completed once. When the water surface buoy moves downwards from the wave crest, the reset tension spring pulls the swing plate to quickly return to the balance position, the piston is driven to move upwards to return to the balance position, and sufficient seawater is sucked into the piston cylinder through the one-way valve I on the inlet of the piston cylinder for filling water into the energy accumulator again, so that the water accumulator is periodically reciprocated, and high-pressure water can be continuously accumulated in the energy accumulator.
When the power buoy for sailing observation needs to move, the electromagnetic stop valve on the pressure nozzle can be opened to spray water outwards, and the movement is realized by utilizing the reaction force of high-pressure water spraying.
An overflow valve is arranged at the bottom of a piston cylinder of the power system, when the interior of the energy accumulator is completely filled with seawater, the overflow valve can be used for discharging redundant seawater, so that the following wave swing of an upper swing plate and a lower swing plate of the bionic body can not be blocked due to the fact that water cannot be injected into the energy accumulator, and meanwhile, the water injection pressure of the piston cylinder can be adjusted by adjusting the overflow pressure of the overflow valve.
The solar power generation system on the water surface buoy can absorb abundant solar energy, converts the absorbed solar energy into electric energy to be stored in the storage battery, and supplies power for navigation, positioning, data acquisition and the like of the solar power generation system; the bionic body and the power system can effectively convert wave energy and store the converted wave energy for driving the buoy to navigate.
