Wave power generation device based on drilling platform

Abstract

The invention discloses a wave power generation device based on a drilling platform. The wave power generation device based on the drilling platform comprises a drilling platform body, an annular wave receiving body, a turbine blade and vibration floater assemblies. The annular wave receiving body is fixed around the drilling platform body through corrosion-resistant steel cables. The top portions of the vibration floater assemblies are fixed in the annular wave receiving body, and the bottom portions of the vibration floater assemblies are fixed to the drilling platform body. The turbine blade is fixedly arranged on the annular wave receiving body in a sleeving mode, and the central axis of the turbine blade coincides with the central axis of the annular wave receiving body. Each vibration floater assembly comprises an arc blade arranged inside the annular wave receiving body, and mechanical energy of the arc blades and the turbine blade is transmitted to a conversion mechanism in the center of the drilling platform body. Meanwhile, a power generating device is arranged at the bottom of the drilling platform body. An offshore drilling platform and a wave type power generating device are combined; the drilling platform serves as a reliable support and a repairing platform for wave power generation, wave power generation is used for providing energy and electricity for the drilling platform, and therefore the effects of saving energy and reducing emission are achieved.

Description

Technical field [0001] The invention relates to the technical field of ocean power generation, in particular to a wave power generation device based on a drilling platform. Background technique [0002] With the development of society and rapid population growth, energy problems have become increasingly prominent. People have regained recognition of clean and renewable energy, and wave energy has naturally attracted attention as a resource that is almost completely pollution-free and extremely rich in resources. According to statistics, if the average wave height of the world's oceans is 1 meter and the period is 1 second, the global ocean wave energy power is about 70 billion kilowatts, of which about 2.5 billion kilowatts can be developed and utilized, which is similar to tidal energy. However, as the current wave power generation technology is not yet mature, it has not been better utilized. Comprehensive analysis shows that it currently has the following shortcomings: [0003...

AI Technical Summary

Problems solved by technology

However, due to the immaturity of current wave power generation technology, it has not been better utilized. Comprehensive analysis shows that it currently has the following shortcomings:

[0005] 3), the current power generation economy is poor

[0006] The capacity of the power generation device must match the magnitude of the wave force, but the existing information is not detailed enough, and the sea test is difficult to carry out; at the same time, the existing offshore oil wells can only supply power by themselves due to their own structure and function, and the power supply method generally adopts Distributed power generation, that is, mainly wind power generation, with other auxiliary power generation equipment such as fuel power generation

However, these methods are poor in safety and reliability, high in cost and pollute the environment
