[0002] At present, in order to meet the increasingly urgent energy demand, human beings must increase the energy supply, which will lead to environmental problems and energy shortages. In order to solve these problems, people have turned their attention to new energy, including solar energy, wind energy, nuclear energy, geothermal resources, etc. For decades, new energy power generation technologies represented by hydropower, power generation, solar power generation and nuclear power have made great progress with the strong support of governments of various countries. However, according to statistics, although the cost of new energy power generation has been declining year by year, it is still high.

[0003] The ocean occupies 71% of the earth's surface, concentrates 97% of the earth's water, and contains huge energy. Ocean energy mainly refers to the renewable energy that is unique to the ocean and attached to seawater, such as tidal energy, temperature difference energy, tidal energy, ocean current energy, wave energy and salinity difference energy, among which wave energy is the highest-grade ocean energy. With the advancement of ocean development technology, the ocean has become a hot spot for energy development.

[0004] According to statistics from foreign research institutions, the wave energy in the world's oceans reaches 70 billion kilowatts. The use of ocean energy has a very broad application prospect and has become a key area of ​​ocean energy development in countries around the world. Although my country is also a country with a large ocean area, the development and utilization of marine resources is still in the research and experimental and initial stages, and these huge energy sources have not yet been commercially developed and utilized. Summary of the invention

[0005] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a concentrated wave plus gravity power generation system and an offshore ecological platform in view of the current situation of complicated technology, high cost, long construction period and high power generation cost in the existing wave power generation technology.

[0006] The energy-concentrating wave-plus-gravity power generation system and offshore ecological platform described in the present invention are characterized by comprising an equipment support platform and a wave-plus-gravity power generation device installed on the equipment support platform, the wave-plus-gravity power generation device comprising a generator set fixed on the upper surface of the equipment support platform and a buoyancy kinetic energy hammer floating on the water surface, a lever force arm is connected to the power input shaft of the generator set, a power arm is fixed to the top of the lever force arm, both ends of the power arm are respectively connected to a gravity kinetic energy hammer and a rope, the other end of the rope is fixed to the buoyancy kinetic energy hammer, the buoyancy kinetic energy hammer is slidably arranged on a guide column, an upper limit plate and a lower limit plate are respectively installed on the guide columns located above and below the buoyancy kinetic energy hammer, a restriction area is enclosed by the upper limit plate and the lower limit plate to limit the stroke of the buoyancy kinetic energy hammer, the equipment support platform and the guide column are both fixed on the seabed or underwater support platform.

[0007] When a wave crest arrives, the water surface height rises significantly, and the buoyancy of the seawater pushes the buoyancy kinetic energy hammer upward, reducing the pulling force on the power arm. The gravity kinetic energy hammer forms downward pressure on the power arm under the action of gravity, which is then amplified by the lever force arm, forming a huge torque on the power input shaft of the generator set, driving the generator set to generate electricity, and outputting electricity after rectification by the commutator. After the crest, the trough arrives, the water surface height drops significantly, and the buoyancy kinetic energy hammer loses the support of the buoyancy of the seawater. Since the mass of the buoyancy kinetic energy hammer is greater than the mass of the gravity kinetic energy hammer, the buoyancy kinetic energy hammer pulls down the front end of the power arm through the rope.
