Description
技术领域technical field
本发明涉及一种波浪能利用装置，属于海洋波浪能利用领域。The invention relates to a wave energy utilization device, which belongs to the field of ocean wave energy utilization.
背景技术Background technique
波浪能是指海洋表面波浪所具有的动能和势能。波浪的能量与波高的平方、波浪的运动周期以及迎波面的宽度成正比。波浪能是海洋能源中能量最不稳定的一种能源。波浪能是由风把能量传递给海洋而产生的，它实质上是吸收了风能而形成的。Wave energy refers to the kinetic and potential energy of ocean surface waves. The energy of a wave is proportional to the square of the wave height, the period of motion of the wave, and the width of the front facing the wave. Wave energy is the most unstable energy in ocean energy. Wave energy is produced by the wind transferring energy to the ocean, which essentially absorbs wind energy.
全世界波浪能的理论估算值也为109kW量级。利用中国沿海海洋观测台站资料估算得到，中国沿海理论波浪年平均功率约为1.3×107kW。但由于不少海洋台站的观测地点处于内湾或风浪较小位置，故实际的沿海波浪功率要大于此值。其中浙江、福建、广东和台湾沿海为波能丰富的地区。波浪能量如此巨大，存在的如此广泛，自古吸引着沿海的能工巧匠们，想尽各种办法，企图驾驭海浪为人所用。水力可以满足全世界3倍的能源。The theoretical estimate of wave energy in the world is also on the order of 109kW. It is estimated by using the data of China's coastal ocean observation stations that the theoretical annual average power of China's coastal waves is about 1.3×10 7 kW. However, since the observation sites of many marine stations are located in inner bays or where the wind and waves are small, the actual coastal wave power is greater than this value. Among them, Zhejiang, Fujian, Guangdong and the coastal areas of Taiwan are areas rich in wave energy. The wave energy is so huge and exists so widely that since ancient times, it has attracted the skilled craftsmen along the coast to try their best to control the waves for human use. Hydropower can satisfy 3 times the world's energy.
波浪能发电，现在大多数是利用发电部件如浮子直接与海水接触来采集波浪能，然后将采集的波浪能以动能形式传递给液压泵等机构来带动发电机发电。这种方法的不足是波浪能各个部件常年与海水直接接触，受海水的腐蚀破坏严重，这种发电设施与发电厂常建在海岸边，经常要面临海潮与海浪风暴的冲击破坏的威胁。Most of the wave energy power generation uses power generation components such as floats to directly contact seawater to collect wave energy, and then transmit the collected wave energy in the form of kinetic energy to hydraulic pumps and other mechanisms to drive generators to generate electricity. The disadvantage of this method is that all components of the wave energy are in direct contact with seawater all the year round, and are seriously damaged by seawater corrosion. This kind of power generation facilities and power plants are often built on the coast, and often face the threat of impact damage from sea tides and storm waves.
