Abstract

A fluid leak detection system includes a reservoir, a predetermined quantity of a disinfecting liquid contained within such a reservoir, and at least a pair of elongated conduits. A mechanism for automatically opening the distal end of the at least one conduit includes a leaking fluid absorbent member disposed along the distal end of each of the conduits. The fluid-dissolvable member is dissolved by the leaking fluid and absorbed by the member to permit the conduit to be unfolded and allow the disinfecting liquid to flow outwardly from the distal end of the at least one conduit. The system further includes a support frame attached to a support surface, an interface, a communications device electrically coupled to a switch, a monitoring station, and a communications link connecting the communications device to the monitoring station.

Claims

1. A fluid leak detection system for substantially preventing mold and mildew growth, said fluid leak detection system comprising:

a reservoir;

a predetermined quantity of a disinfecting liquid contained within said reservoir;

at least one conduit having one end in fluid communication with said reservoir and having a distal end in an initial closed position; and

means for automatically opening said distal end of said at least one conduit to an open position upon detecting a leaking fluid disposed on a surface external of said at least one conduit such that said disinfecting liquid automatically discharges from said distal end and encounters the detected fluid to substantially prevent mold and mildew growth.

2. The fluid leak detection system of claim 1, wherein said system further includes:

a leaking fluid absorbent member disposed along said distal end of said at least one conduit, said fluid absorbent member extending along a partial longitudinal length of said at least one conduit and spanning outwardly therefrom;

said distal end being folded onto an adjacent portion of said at least one conduit;

a leaking fluid-dissolvable member wrapped about said distal end and said adjacent portion of said at least one conduit such that said disinfecting liquid is prohibited from egress outwardly of said distal end;

said fluid-dissolvable member becoming saturated with the leaking fluid after said fluid absorbent member becomes saturated by the leaking fluid, said fluid-dissolvable member being dissolved by the leaking fluid and absorbed by said member to permit said at least one conduit to be unfolded and allowing said disinfecting liquid to flow outwardly from said distal end of said at least one conduit.

3. The fluid leak detection system of claim 2, further including:

a support frame attached to a support surface, said reservoir being anchored to said support frame and maintained at an elevated position above said distal end of said conduit so that said disinfecting liquid is allowed to freely flow downstream along said at least one conduit after said distal end is in said open position.

4. The fluid leak detection system of claim 3, further including an electrical switch located between said reservoir and said support surface, a low voltage electrical source and an alarm, said switch becoming open upon general depletion of said disinfecting liquid in said reservoir and activating said alarm.

5. The fluid leak detection system of claim 4, further including:

an interface electrically coupled to an existing fluid source control valve of the leaking fluid;

said switch when open activates said interface upon detecting the leaking fluid, said interface turning said control valve of the leaking fluid to a closed position for eliminating continuance of the leaking fluid.

6. The fluid leak detection system of claim 4, further including:

a communications device electrically coupled to said switch;

a monitoring station; and

a communications link connecting said communications device to said monitoring station;

said communications device automatically notifying said monitoring station of the leaking fluid when said switch activates said communication device.

7. The fluid leak detection system of claim 1, wherein said disinfecting liquid is an antimicrobial liquid to prevent mold and mildew growth.

10. The fluid leak detection system of claim 7, further including:

a support frame attached to a support surface, said reservoir being anchored to said support frame and maintained at an elevated position above said distal ends of said conduits so that said disinfecting liquid is allowed to freely flow downstream along said at least one conduit after said distal end is in said open position.

11. The fluid leak detection system of claim 10, further including an electrical switch located between said reservoir and said support surface, a low voltage electrical source and an alarm, said switch becoming open upon general depletion of said disinfecting liquid in said reservoir and activating said alarm.

12. The fluid leak detection system of claim 11, further including:

an interface electrically coupled to an existing fluid source control valve of the leaking fluid;

said switch when open activates said interface upon detecting the leaking fluid, said interface turning said control valve of the leaking fluid to a closed position for eliminating continuance of the leaking fluid.

13. The fluid leak detection system of claim 11, further including:

a communications device electrically coupled to said switch;

a monitoring station; and

a communications link connecting said communications device to said monitoring station;

said communications device automatically notifying said monitoring station of the leaking fluid when said switch activates said communication device.

14. The fluid leak detection system of claim 7, wherein said disinfecting liquid is an antimicrobial liquid to prevent mold and mildew growth.

15. A method for substantially preventing mold and mildew growth by said system according to claim 1, said method comprising the steps of:

a) providing said reservoir;

b) depositing a predetermined quantity of a disinfecting liquid into said reservoir;

c) connecting one end of at least one conduit to said reservoir;

d) closing a distal end of said at least one conduit to an initial closed position by folding said distal end onto an adjacent portion of said at least one conduit; and

e) automatically opening said distal end of said at least one conduit to an open position upon detecting a leaking fluid disposed on a surface external of said at least one conduit such that said disinfecting liquid automatically discharges from said distal end and encounters the detected fluid to substantially prevent mold and mildew growth.

16. The method of claim 15, wherein step e) includes the steps of:

wrapping a leaking fluid-dissolvable member about said distal end and said adjacent portion of said at least one conduit such that said disinfecting liquid is prohibited from egress outwardly of said distal end;

disposing a leaking fluid absorbent member along said distal end of said at least one conduit by extending outwardly said leaking fluid absorbent member along a partial longitudinal length of said at least one conduit;

dissolving said fluid-dissolvable member when said fluid-dissolvable member becomes saturated and thereby permitting said at least one conduit to be unfolded; and

allowing said disinfecting liquid to flow outwardly from said distal end of said at least one conduit.

17. The method of claim 15, further including the steps of:

disposing a support frame on a support surface adjacent an area likely to have a leaking fluid

anchoring said reservoir to said support frame; and

maintaining said reservoir at an elevated position above said distal end of said conduit so that said disinfecting liquid is allowed to freely flow downstream along said at least one conduit after said distal end is in said open position.

18. The method of claim 17, further including the steps of:

locating an electrical switch between said reservoir and said support surface;

connecting a low voltage electrical source to an alarm; and

said interface turning said control valve of the leaking fluid to a closed position for eliminating continuance of the leaking fluid.

20. The method of claim 19, further including the steps of:
