[0030] Detailed content introduction:

[0031] A comprehensive power generation system for buoyancy, gravity, and waves. By draining water through the hydraulic piston rod 71, the water inside the outer floating cylinder 62 is discharged to generate air, causing the outer floating cylinder 62 to emerge from the water surface and driving the generator 44 to generate electricity simultaneously. At the same time, waves can also be generated, and the waves are converted into kinetic energy to drive the generator 44 to generate electricity. The hydraulic piston rod 71 automatically retracts due to the weight of the inner floating cylinder 61, the air is discharged, water is inhaled, and it sinks while generating gravitational power generation and wave power generation simultaneously. Emerging from the water surface at a depth of 50 meters drives the generator 44 to generate electricity. According to the experimental results of the 200L outer floating cylinder 62: 100L of buoyancy can generate 1KW of electricity, and the floating speed: when the 200L drives a 2KW generator 44 under load, the floating speed is 50 meters in 60 seconds, and the stable voltage generated by the generator 44 can be 240V. Gravity: After the outer floating cylinder 62 emerges from the water surface and exhausts air, water enters the outer floating cylinder 62, and the sinking of the outer floating cylinder 62 drives the generator 44 to generate electricity. The total weight of the outer floating cylinder 62 and the transmission shaft gear is 80kg, which can drive the generator 44 to generate a stable voltage of 0.8KW. Wave power generation: There are two types of wave power generation that can be recovered. One is the wave power generation generated by nature, and the other is the wave power generation generated when the outer floating cylinder 62 emerges from the water surface and the wave power generation generated when the outer floating cylinder 62 sinks to the bottom. The electricity generated by the waves is determined by the size of the outer floating cylinder 62. The drainage and exhaust mechanism 7 uses the hydraulic piston rod 71 to do work, and the power consumption at the same time: The outer floating cylinder 62 with a diameter of 1900 mm and a height of 1500 mm requires a thrust of 127.17 tons for exhaust and drainage at a depth of 50 meters underwater, which is 90 square centimeters * 90 square centimeters * 3.14 * 5. When using the hydraulic piston rod 71 for drainage, a 150t thrust requires 380V, 15KW, a 1500 mm stroke, and 48 seconds. In the case of load pushing, it takes 48 seconds to 60 seconds. 0.9 meters * 0.9 meters * 3.14 * 1.5 meters = 3.8151 cubic meters = 3815.1L * 1.43 buoyancy = 5.455593 tons. According to the experimental data, 100L of buoyancy produces 1KW of data, and the self-weight can be designed to be about 2.7277965 tons, enabling the outer floating cylinder 62 to generate a maximum of 27KW of electricity when floating up and down. Calculated as follows: According to the above experimental data, it takes 15KW of electricity for one work in 48 seconds, and it can generate 27KW in 120 seconds. The power supply to the power supply bureau is: 12KW of buoyancy power generation in 12 seconds and 27KW of gravitational power generation in 60 seconds. When 4 outer floating cylinders 62 operate simultaneously, continuous power supply for 24 hours can be achieved. When 60 outer floating cylinders 62 do work up and down, waves can be generated once per second. In this case, a wave power generation device can be directly purchased on the market and installed on the shore for direct power generation. The capacity depends on the height of the waves.
