This creation is related to a kind of antifreeze body structure and the fishing pond winterization system using that,The antifreeze body include a shell,Insulating layer and one in one filling what shell set the buoyancy layer in what insulating layer center,Wherein insulating layer be selected from it is light,And have the material every cold effect,And buoyancy series of strata are to have the material of buoyancy,Thereby,Cover antifreeze body can with what on the water surface in what fishing pond,Through the covering of antifreeze body,It generates every cold effect,The problem for avoiding causing aquatic products inadaptable and dead because rapidly cooling down,This creation is not only easy to use and operate,And every cold and time-histories excellent,With more environmental protection,The benefits of durable.本創作涉及一種防凍體結構及應用彼之漁池防凍系統，該防凍體包含有一外殼、一充填於外殼內之保溫層及一設於保溫層中央的浮力層，其中保溫層選自質輕、且具隔寒效果之材質，而浮力層係為具浮力之材質，藉此，使防凍體可用於覆蓋於漁池的水面上，透過防凍體的覆蓋，產生隔寒效果，避免因急遽降溫而造成水產不適應而死亡的問題，本創作不僅使用操作方便，且隔寒及時程效果極佳，更具有環保、耐久之效。
