[0002] Today, land-based mineral fuels are becoming increasingly depleted, pollution has become more serious, and energy security and energy environment issues are becoming more and more of a high-profile issue for all sectors of the domestic and international community. Scientists from all over the world are working hard to research, develop and utilize new energy sources, and some major maritime countries in the world have turned their attention to the ocean. Seawater is a huge energy reservoir. As long as there is seawater, ocean energy will never be exhausted, and the development of ocean energy will not produce wastewater and exhaust gas, nor will it occupy large tracts of fertile land, and there will be no radiation pollution. Therefore, ocean energy is called the green energy of the 21st century. More importantly, the wave energy, tidal energy and tidal energy in ocean energy also have an advantage that wind energy and solar energy cannot match, that is, predictability. Tides caused by changes in the moon's gravity can be accurately predicted several years in advance, and ocean current maps can be accurately drawn by satellite. my country has a huge prospect for exploitable ocean energy resources, and the development of ocean energy is one of the development directions of my country's energy strategy.

[0003] After searching Chinese patents, a wave energy power generation device with the publication number CN106762367B was found, which solves the problems of low utilization rate of wave energy and high manufacturing cost of existing wave energy power generation devices. The wave energy power generation device includes a base, a hydraulic cylinder, a hydraulic motor and a generator. The base can be fixed on the shore, the cylinder body of the hydraulic cylinder is fixed on the base, the hydraulic cylinder and the hydraulic motor are connected in series through pipelines to form a loop, the output shaft of the hydraulic motor is connected to the input shaft of the generator, and the end of the piston rod is provided with a connecting plate that can be connected to the ship. In this design, there is no need to change the structure of the existing ship, nor to add additional equipment to the ship, and the wave energy can be effectively utilized when the ship is docked.

[0004] The existing offshore power generation devices have low power generation efficiency. Generally, the power generation method of offshore power generation devices is relatively single, either through tidal power generation or through wave power generation. The single power generation method greatly reduces the utilization of energy and causes energy waste. If tidal energy and wave energy need to be used at the same time, corresponding power generation devices need to be used separately, which increases the cost of power generation, increases the maintenance amount, and is inconvenient to use. In order to solve the above problems, we propose a floating offshore power generation device that integrates wave energy and tidal energy. Summary of the invention
