The utility model provides a floating ball structure, in application, the floating ball needs to be dumped on the aquaculture area in large quantities to cover the water surface of the aquaculture area in large areas, the structure includes: a closed spherical surface, which is one of the spherical shell closures in external form； and a holding space, which is an internal space covered by the closed ball.Through the application of the floating ball in different embodiments, the cold air is isolated by covering the cultivation area with the floating ball, so as to prevent the cold air from quickly taking away the heat energy of the pool water in the cultivation area, and even further enable the floating ball to release the heat energy to the pool water in the cultivation area for heat preservation and even generate the effect of heat energy heating.本新型提供一種浮球結構，應用時需將該浮球大量傾倒於養殖區，以大面積覆蓋於養殖區之水面上，其結構包含：一封閉球面，係為外型為球體之一薄殼封閉體；以及一容置空間，該容置空間係為被該封閉球面包覆的內部空間。並透過不同實施例的浮球應用，利用浮球覆蓋於養殖區的方式隔絕冷空氣，防止冷空氣快速帶走養殖區中池水的熱能，甚至更進一步讓該浮球對養殖區中的池水進行釋放熱能保溫甚至產生熱能加溫的效果。
