Patent ID: 7355147

Claim:
An ice removal for a pond to emit heat from its surface, said ice removal comprises: an upper cover; a lower cover connected with said upper cover in a waterproof mode to form a hollow floating member; a heat emitting cup mounted on an external bottom of said lower cover in a waterproof mode, said heat emitting cup is installed inside its bottom with a heat emitting source that generates heat energy to be transmitted to an outer surface of said heat emitting cup; a helical heat emitting wire mounted on an inner top surface of said upper cover in a contact mode; an electric circuit board mounted on an inner bottom of said lower cover, a tailing end of said helical heat emitting wire and a tailing end of said heat emitting source are both connected to said electric circuit board; and an electric power line is extended in from outside of said heat emitting cup to connect said circuit board to supply electric power; after power supplying of said electric power line, said helical heat emitting wire generates heat energy to keep outer surface temperature of said upper cover above that for snow melting, and said heat emitting source in said heat emitting cup generates heat energy to keep temperature outside of said heat emitting cup above freezing point.
