1. Field of the Invention
The present inventions relates to an ice removal for a pond, and especially to an ice removal that can keep the surface temperature of the pond higher than about 5° C.
2. Description of the Prior Art
An ice removal for a pond is placed on the surface of water of a pond or a water bucket for breeding living things; when in a cold weather, the heat emitting from the ice removal for a pond is used to prevent freezing of the surface of water that may seal the water therebelow to be unable to contact with and obtain fresh air from the outside.
A conventional ice removal for a pond is loaded with a heat emitting means in a floating member; the heat emitting means generally is mounted on the bottom of the floating member or surrounds the inner periphery of the floating member. When the ice removal is used in a quite cold circumstance such as in a snowing weather, snowdrifts are subjected to being accumulated on the surface of the ice removal; if the ice removal is covered over, its position is uneasy to be found, this is a disadvantage in use of the conventional ice removal for a pond, and improvement is expected.
The present invention provides an ice removal for a pond to emit heat from its surface; the ice removal comprises a disk shaped upper cover, a disk shaped lower cover and a heat emitting cup, it can float on the surface of water. An electric circuit board is mounted on an inner bottom of the lower cover, and a helical heat emitting wire is mounted on the inner top surface of the upper cover in a contact mode, and the cup having a heat emitting source is mounted on the outer bottom surface of the lower cover. An electric power line is extended in from the bottom of the heat emitting cup to connect the circuit board to supply electric power, so that the helical heat emitting wire keeps the surface temperature of the upper cover above 5° C., so that the surface of the entire ice removal will not be covered by snow or ice, while the heat emitting cup can emit heat under the water for removing ice. Thereby, the defect of covering over the conventional ice removal for a pond can be overcome.
The ice removal for a pond to emit heat from its surface provided by the present invention has partitions on the inner top surface of its upper cover to form fixing means for mounting the helical heat emitting wire; thereby the helical heat emitting wire is tightly contacted with the upper cover.
The present invention will be apparent in its structure and effect of use to be achieved after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
Referring to
The peripheries of the upper cover 10 and the lower cover 20 are tightly contacted with each other to provide a function of water proofing, after assembling of them, a round disk shape or any other flat shape can be formed, for instance, an elliptic or a rectangular shape. An electric circuit board 40 is mounted on an inner bottom of the lower cover 20, the electric circuit board 40 is fixed above the heat emitting cup 30; while the upper periphery of the heat emitting cup 30 is mounted on the external bottom of the lower cover 20 in a waterproof mode. The heat emitting cup 30 is made of metal such as aluminum, the heat emitting cup 30 is installed inside the bottom of it with a circle of heat emitting source 31 that can generate heat energy to be transmitted to the outer surface to keep the surface temperature above the freezing point, in order that water will not freeze. Certainly, the tailing end of the heat emitting source 31 is connected to the electric circuit board 40.
An electric power line 60 is extended in from the central bottom of the heat emitting cup 30 in a waterproof mode, and is connected to the electric circuit board 40 for power supplying.
Referring to
The upper cover 10 is provided centrally thereof with an indicating lamp 70 to show whether the circuit is turned on by its lightening and extinguishing.
In conclusion, the present invention will have no snowdrifts on the outer surface of the upper cover 10, a user can find the position where the present invention is very easily even in a snowy weather. And the heat emitting cup 30 provides heat energy to prevent water from freezing, so that the water can contact with and obtain fresh air from the outside to keep the living things bred in a pond or a water bucket alive.
Having thus stated the present invention in detail, it can be understood that the present invention can have other embodiments as well as changes without departing from the spirit of it and the scope stated in the claims.
