The utility model has a stable buoy structure, which is characterized in that: a guiding trough is arranged on the tail section of the body, and when the water flow impacts the buoy body, the water flow can flow from the diversion trough, so that the buoy can achieve a stable effect when it is on the water surface.一種具穩定浮標結構,其特點在於:本體的標尾段上設置有一導流槽,當水流沖擊浮標本體時,水流能從導流槽流過,使得浮標在水面時能達到穩定的效果。
