Abstract

A deicing system includes a heating element configured to impart heat to water within a water-retaining structure, a guard configured to prevent the heating element from abutting surfaces of the water-retaining structure, and a securing spring that securely fastens the heating element to the guard.

Claims (36)

1. A deicing system configured to be positioned within a water-retaining structure, wherein the deicing system is configured to prevent ice from forming within the water-retaining structure, the deicing system comprising:

a heating element configured to impart heat to water within the water-retaining structure;

a guard configured to prevent said heating element from abutting surfaces of the water-retaining structure; and

a securing spring that securely fastens said heating element to said guard, wherein said securing spring comprises internal coil surfaces that are threaded.

2. The deicing system of claim 1 , wherein said guard is a wire-frame guard comprising a base integrally secured to a cross-beam through braces, wherein said securing spring compressively winds around said cross-beam and said heating element.

3. The deicing system of claim 1 , wherein said securing spring securely fastens said heating element to said guard without separate and distinct fasteners.

4. The deicing system of claim 1 , wherein said securing spring comprises a plurality of evenly-spaced coils.

5. The deicing system of claim 1 , wherein said securing spring comprises intermediate coils and a terminal coil, wherein a spacing between a terminal coil and an adjacent intermediate coil is less than a spacing between two intermediate coils.

6. The deicing system of claim 1 , wherein said securing spring wraps around said heating element and a portion of said guard about a central longitudinal axis of said securing spring.

7. The deicing system of claim 1 , wherein said heating element comprises a caloric rod.

8. A deicing system configured to be positioned within a water-retaining structure, wherein the deicing system is configured to prevent ice from forming within the water-retaining structure, the deicing system comprising:

a heating element configured to impart heat to water within the water-retaining structure;

a wire-frame guard configured to prevent said heating element from abutting a surface of the water-retaining structure, wherein said wire-frame guard comprises a base integrally secured to a cross-beam through braces; and

a securing spring that securely fastens said heating element to said wire-frame guard, wherein said securing spring comprises internal coil surfaces that are threaded, wherein said securing spring wraps around said heating element and a portion of said guard about a central longitudinal axis of said securing spring, and wherein said securing spring compressively winds around said cross-beam and said heating element.

9. The deicing system of claim 8 , wherein said securing spring securely fastens said heating element to said guard without separate and distinct fasteners.

10. The deicing system of claim 8 , wherein said securing spring comprises a plurality of evenly-spaced coils.

11. The deicing system of claim 8 , wherein said securing spring comprises intermediate coils and a terminal coil, wherein a spacing between a terminal coil and an adjacent intermediate coil is less than a spacing between two intermediate coils.

12. The deicing system of claim 8 , wherein said heating element comprises a caloric rod.

13. A deicing system, comprising:

a heating element comprising a caloric rod, wherein said caloric rod is configured to impart heat to water within a water-retaining structure;

a wire-frame guard configured to prevent said heating element from abutting a surface of the water-retaining structure, wherein said wire-frame guard comprises a base integrally secured to a cross-beam through braces, wherein said braces are configured to suspend said heating element above a basin of the water-retaining structure, and wherein said base, said cross-beam and said braces are configured to prevent said heating element from abutting walls of the water-retaining structure; and

a securing spring that securely fastens said heating element to said wire-frame guard, wherein said securing spring comprises internal coil surfaces that are threaded, wherein said securing spring wraps around said heating element and a portion of said guard about a central longitudinal axis of said securing spring, wherein said securing spring compressively winds around said cross-beam and said heating element, and wherein said securing spring is devoid of separate and distinct fastener such that said securing spring securely fastens the heating element to the wire-frame guard without separate and distinct fasteners.

14. The deicing system of claim 13 , wherein said securing spring comprises a plurality of evenly-spaced coils.

15. The deicing system of claim 13 , wherein said securing spring comprises intermediate coils and a terminal coil, wherein a spacing between a terminal coil and an adjacent intermediate coil is less than a spacing between two intermediate coils.

16. A deicing system configured to be positioned within a water-retaining structure, wherein the deicing system is configured to prevent ice from forming within the water-retaining structure, the deicing system comprising:

a heating element configured to impart heat to water within the water-retaining structure;

a guard configured to prevent said heating element from abutting surfaces of the water-retaining structure; and

a securing spring that securely fastens said heating element to said guard, wherein said securing spring comprises intermediate coils and a terminal coil, wherein a spacing between a terminal coil and an adjacent intermediate coil is less than a spacing between two intermediate coils.

17. A deicing system configured to be positioned within a water-retaining structure, wherein the deicing system is configured to prevent ice from forming within the water-retaining structure, the deicing system comprising:

a heating element configured to impart heat to water within the water-retaining structure;

a wire-frame guard configured to prevent said heating element from abutting a surface of the water-retaining structure, wherein said wire-frame guard comprises a base integrally secured to a cross-beam through braces; and

a securing spring that securely fastens said heating element to said wire-frame guard, wherein said securing spring comprises intermediate coils and a terminal coil, wherein a spacing between a terminal coil and an adjacent intermediate coil is less than a spacing between two intermediate coils, wherein said securing spring wraps around said heating element and a portion of said guard about a central longitudinal axis of said securing spring, and wherein said securing spring compressively winds around said cross-beam and said heating element.

18. A deicing system, comprising:

a heating element comprising a caloric rod, wherein said caloric rod is configured to impart heat to water within a water-retaining structure;

a wire-frame guard configured to prevent said heating element from abutting a surface of the water-retaining structure, wherein said wire-frame guard comprises a base integrally secured to a cross-beam through braces, wherein said braces are configured to suspend said heating element above a basin of the water-retaining structure, and wherein said base, said cross-beam and said braces are configured to prevent said heating element from abutting walls of the water-retaining structure; and

a securing spring that securely fastens said heating element to said wire-frame guard, wherein said securing spring comprises intermediate coils and a terminal coil, wherein a spacing between a terminal coil and an adjacent intermediate coil is less than a spacing between two intermediate coils, wherein said securing spring wraps around said heating element and a portion of said guard about a central longitudinal axis of said securing spring, wherein said securing spring compressively winds around said cross-beam and said heating element, and wherein said securing spring is devoid of separate and distinct fastener such that said securing spring securely fastens the heating element to the wire-frame guard without separate and distinct fasteners.
