AI Technical Summary
Technical Problem
”；该组件通过设置的降噪壳、隔音板和吸音棉的配合使用，从而使风力发电机工作所产生的噪声，通过降噪壳起到一定的降噪作用，同时缓冲机构也起到辅助降噪的作用，降低风力发电机工作所产生的刺耳噪声，但是该组件中所使用的隔音板为市场上常见的板状隔音板，其隔音效果基本上是靠自身的材质特性，使得隔音板的噪音抑制效果存在较大的浮动，而材质好的隔音板，虽然噪音抑制效果好，然而价格也相对较贵，同时单纯的板状结构，使得隔音板自身的结构强度较低，容易出现损坏问题
Benefits of technology
[0012]与现有技术相比，本实用新型的有益效果是：通过板体、密封板、降噪液和吸音海绵的配合，能够有效增强该隔音板对噪音的抑制效果，并且通过传播介质的多重变换，能够进一步增强该隔音板的降噪效果，同时，通过定位杆、密封板和加固条的配合，能够有效增强该隔音板整体的结构强度，从而降低该隔音板出现意外损坏的几率。
