Description
技术领域technical field
本发明属于海洋能利用领域，涉及风能-波浪能综合利用装置，尤其涉及一种基于单桩平台垂直轴风力机与垂向-水平两向波浪能发电集成结构。The invention belongs to the field of ocean energy utilization, and relates to a wind energy-wave energy comprehensive utilization device, in particular to an integrated structure based on a single pile platform vertical axis wind turbine and vertical-horizontal two-way wave energy generation.
背景技术Background technique
海上风能和波浪能都是清洁可再生的海洋能源，可利用风力发电机将风力能转换成电能，利用波浪发电装置将波浪能转换成电能。我国东部沿海的海上可开发风能资源约达7.5亿千瓦，不仅资源潜力巨大，而且开发利用市场条件良好，更靠近中国的经济中心。海上风能开发具有节约宝贵土地资源、风力更稳定、风电机组单机容量更大、年有效利用小时数更高、受噪音标准限制更小、运输条件更为便利等优势。风能丰富水域的波浪能资源也很丰富。但是，相比于海上风力发电，波浪能发电装置能量转化率较低，单位发电成本较高，一定程度限制了其商业化应用。Offshore wind energy and wave energy are both clean and renewable ocean energy. Wind power generators can be used to convert wind energy into electrical energy, and wave power devices can be used to convert wave energy into electrical energy. The exploitable offshore wind energy resources in the eastern coast of my country are about 750 million kilowatts, which not only has huge resource potential, but also has good market conditions for development and utilization, and is closer to China's economic center. Offshore wind energy development has the advantages of saving precious land resources, more stable wind power, larger wind turbine unit capacity, higher annual effective utilization hours, less restricted by noise standards, and more convenient transportation conditions. Wave energy resources are also abundant in wind-rich waters. However, compared with offshore wind power generation, the energy conversion rate of wave power generation devices is lower, and the unit power generation cost is higher, which limits its commercial application to a certain extent.
现有技术中，近海风力发电装置的基础主要有单桩式、多桩式、重力式、导管架式、高桩承台式等固定式支撑平台结构，其中，单桩式平台以其施工便利、建造成本低、适用性强等优势，应用最为广泛。波浪能发电装置的种类繁多，不拘一格，有点头鸭式、波面筏式、波力发电船式、环礁式、整流器式、海蚌式、软袋式、振荡水柱式、多共振荡水柱式、波流式、摆式、结合防波堤的振荡水柱式、收缩水道式等十余种。In the prior art, the foundations of offshore wind power generation devices mainly include fixed support platform structures such as single pile type, multi-pile type, gravity type, jacket type, and high pile cap type. Among them, the single pile type platform is convenient for construction, Low construction cost, strong applicability and other advantages, the most widely used. There are many types of wave energy generating devices, eclectic, nodding duck type, wave surface raft type, wave power generation ship type, atoll type, rectifier type, sea clam type, soft bag type, oscillating water column type, multi-common oscillating water column There are more than ten types such as wave type, wave flow type, pendulum type, oscillating water column type combined with breakwater, shrinking channel type, etc.
现有技术的不足是：波浪能发电装置能量转化率较低，单位发电成本较高，且缺少同时利用两向及多向相对运动获取波浪能的发电装置结构系统。目前还非常缺少将垂直轴风力机与多向波浪能发电装置集成为一体的海洋能源综合开发结构系统。The deficiencies of the prior art are: the energy conversion rate of the wave power generation device is low, the unit power generation cost is high, and there is a lack of a power generation device structural system that simultaneously utilizes two-way and multi-way relative motion to obtain wave energy. At present, there is still a lack of a comprehensive marine energy development structure system that integrates vertical axis wind turbines and multi-directional wave energy generation devices.
