Abstract
Description
Technical Field
[0001] The utility model relates to a power generation device, in particular to a suspended ocean wave power generation device. Background Art
[0002] In today's world, facing the depletion of fossil fuels, people are constantly searching for new renewable energy sources to meet their growing energy needs. The ocean, covering 71% of the Earth's surface, holds immense energy resources. It is a truly inexhaustible treasure trove of energy bestowed upon us by nature. When it comes to ocean energy, the first thing that comes to mind is the kinetic energy contained in the surging waves. As early as 1977, estimates of ocean waves across the world's oceans showed that global wave power was approximately 70 billion kilowatts, of which approximately 2.5 billion kilowatts were potentially exploitable. If this wave kinetic energy could be perfectly converted into electricity, the annual power generation would reach 21,900 terawatt-hours (TWh). It's worth noting that global power generation in 2019 was approximately 26,990 TWh. Fully utilizing the kinetic energy of ocean waves for power generation would significantly alleviate humanity's energy challenges.
[0003] Two types of wave generators are currently in operation: 1. The Pelamis wave generator, with its main body resembling a sea snake, consists of four cylindrical stainless steel pontoons articulated by three dynamic joints. It is 120 meters long, with a diameter of 3.5 meters and weighing 750 tons. Its design rated power is 750 kW. However, its disadvantages include its large size, difficulty in installation, long manufacturing cycle, high manufacturing costs, and high operating and maintenance costs. Its large size hinders navigation, making it unsuitable for global deployment and limiting its operation to specific sea areas. 2. The WEPTOS wave generator, shaped like a large pair of tweezers, features ten rotors mounted on two 8-meter-long legs. These rotors oscillate continuously with the rise and fall of waves. A mechanical device transfers torque in the same direction to the main shaft. A generator is located at the junction of the two main shafts. The mechanical energy transmitted by the rotors to the main shaft drives the generator to generate electricity. Its disadvantages are that it is bulky, difficult to install, has a long manufacturing cycle, high manufacturing cost, high operation and maintenance cost, complex structure and low reliability. Due to its large size, it affects the navigation of ships and cannot be deployed in global waters. It can only work in specific waters. Utility Model Content
