The present invention provides a grooved buoy structure, the structure comprising: a first body, the first body is provided with at least one first annular groove, and the density of the first body is less than the density of water； The tail end extends from the top of the first body, and is provided with at least one first marking line； and a foot end extending from the bottom end of the first body. The main feature of the novel is that, by the annular groove provided on the buoy body, the buoy can be stabilized on the water surface when floating on the water surface, and the misalignment of the irregular settlement is prevented by the inclination of the buoy.本新型提供一種具凹槽的浮標結構，其結構包括：一第一標身，第一標身設置有至少一第一環狀凹槽，且第一標身之密度小於水的密度；一標尾端，延伸自第一標身之頂端，設置有至少一第一標線；以及一標腳端，延伸自第一標身之底端。本新型之主要特點在於，藉由浮標標身上設置的環狀凹槽，可使浮標在水面上浮沉時，具有在水面穩定的效果，避免浮標傾斜形成不規則沉降形成的誤判。
