Float, to prevent the formation of ice on a garden pond or fishing pool, has hard foam components forming a hollow cone with an adjustable weight and forced ventilation

摘要

The float, to prevent the formation of ice on water surface, is composed of two hard foam components (1,2), an outer ring weight (3) to set a variable floating depth and two eyelet hooks (4,5). The lower component (1) is round and conical, with an open top, fitted with three spacers (6) for ventilation. The upper component (2) is round, with a center plug (7), and rests on the spacers with a supended weight.. Heat from the water passes up through the assembly, to pass out through the lateral ventilation.
