specific embodiment

As shown in the figure, a surge floating energy power generation device includes buoys, pistons, valves, and generator sets. The buoy 1 is hollow and sealed, and is equipped with an automatic controllable tensioning device for steel cables, floating on the sea surface. Piston is contained in the hydraulic cylinder block 8, and the piston handle 3 stretches out of the hydraulic cylinder block 8, and four steel cables 2 are connected with the underwater piston handle 3 outside the hydraulic cylinder block 8. The piston and the piston handle are integrated, the top of the piston is provided with a one-way water inlet valve 4, and the return spring 5 is connected to the piston and the hydraulic cylinder body 8. A one-way water outlet valve 6 is installed on the hydraulic cylinder block 8 . When the piston moves upward, the seawater in the hydraulic cylinder 8 generates pressure to close the water inlet valve 4, and the compressed return spring 5 pushes the one-way water outlet valve 6, and enters the energy storage cylinder 7 through the high-pressure water pipe 11. A piston, an energy storage spring 12 and a boost pressure regulating valve 13 are housed in the energy storage cylinder 7 . The amount of water in the energy storage cylinder 7 increases, and the water pressure increases, so that the piston compression spring 12 of the energy storage cylinder 7 is retreated, and the high-pressure water is delivered to the water turbine or hydraulic motor to drive the generator to generate electricity. Four lugs 9 are arranged on the outer end surface of the lower part of the hydraulic cylinder body 8 to connect with the four anti-corrosion columns respectively. The anti-corrosion column 10 is fixedly connected to the hydraulic cylinder block 8 in the sea or. Or connect an overweight object at the lower end of the cable to fix the hydraulic cylinder 8.

When the swell comes, the buoy rises with the wave, and the steel cable connected with the buoy also rises to pull the piston handle, so that the piston handle pushes the piston upward. The water in the cylinder is under pressure, the piston tops the water inlet valve and closes, the piston moves upward to compress the return spring, and the high-pressure water tops the outlet valve to flow into the energy storage cylinder through the high-pressure water pipe, and the energy storage cylinder can receive high-pressure water from multiple hydraulic cylinders . The water volume in the energy storage cylinder increases, and the water pressure increases, so that the piston compression spring of the energy storage cylinder retreats, and the high-pressure water is delivered to the water turbine or hydraulic motor to drive the generator to generate electricity. The energy storage capacity of the energy storage cylinder should be designed according to the surge frequency and the flow and pressure required by the water wheel or hydraulic motor.

When the swell recedes and the buoy sinks, the piston moves downward under the action of the return spring. Because the pressure in the cylinder is lower than the seawater pressure, the water outlet valve is closed and the water inlet valve is opened. The water is filtered by the filter at the bottom of the piston and enters from the top of the piston. The valve goes into the hydraulic cylinder. Such a cycle, again and again.
