基于链条传动的振荡浮子发电装置转换性能试验研究

Experimental study on transmission performance of oscillating buoy wave energy converter

针对振荡浮子式波浪能发电系统中波浪能的俘获及传递效率较低的问题,文章设计了一种基于链条传动的波浪能转换装置。该装置以链条传动的结构形式将波浪力推动浮子的上下运动转换为链轮的旋转运动,并输出扭矩,从而带动发电系统发电。文章对基于链轮链条传动的振荡浮子式波浪能转换装置的随波特性及能量转换特性进行了研究,研究结果表明:基于链条传动的振荡浮子的随波特性和能量转换特性良好;随着波浪环境的变化,振荡浮子会出现自振动现象;适当增加振荡浮子的质量,能有效提高波浪能的俘获效率,从而提高系统的发电效果;基于链轮链条的传动结构设计存在速度突变现象,合理设计链轮链条之间的啮合间隙,增加链传动的张紧装置,能减缓链条链轮之间的冲击,从而延长装置的使用寿命。

In order to meet the efficiency problem of oscillating buoy wave energy converter,a wave energy converter with chain was designed.The device converts the up and down motion of the buoy into the rotational motion of the sprocket and outputs the torque.In this paper,based on the experimental method to study the oscillating buoy wave energy converter.The results show that the oscillating buoy based on chain has good wave-following characteristics.The energy conversion characteristics is good.The buoy will self-oscillate with the change of wave environment.Increasing the weight of buoy can effectively improve the efficiency of wave energy capture.There is a variation of velocity in the conversion device.Rational design chain structure can reduce striking and prolong the service life of the device.
