Remotely actuated quick connect/disconnect coupling
View Patent ↗A water flushing system for a pressurized subterranean water distribution system includes an inlet conduit for receiving pressurized water from the subterranean water distribution system; an outlet fluidly connected to the inlet conduit for discharging pressurized water in the inlet conduit downwardly towards a drain; and a control valve for controlling the flow of pressurized water in the inlet conduit. The water flushing system further includes one or more of the following features: a freeze protection assembly, a detachable coupling system, a dechlorination system, and a backflow prevention system.
1. A remote latch system for a partially below ground water flushing apparatus comprising:
a pressurized subterranean water distribution system;
a water flushing apparatus having a flow controlled passage with an inlet adapted for fluid connection to the pressurized water distribution system, a first portion of the water flushing apparatus being above ground and including an outlet, a second portion of the flow controlled passage being below ground, wherein water from the water distribution system exiting the outlet is directed downwardly toward the ground;
a flow control valve disposed along the flow controlled passage for selectively permitting and prohibiting the flow of pressurized water through the flow controlled passage;
a programmable controller operatively associated with the flow control valve, wherein the controller regulates the flow of pressurized water received from the water distribution system through the flow controlled passage by activating and deactivating the flow controlled valve on a predetermined timed basis;
a quick connect/disconnect coupling for detachably coupling the pressurized subterranean water distribution system and the inlet of the water flushing apparatus, the quick connect/disconnect coupling having a locked mode, in which the pressurized subterranean water distribution system and the inlet of the water flushing apparatus are coupled, and an unlocked mode, in which the pressurized subterranean water distribution system and the inlet of the water flushing apparatus are decoupled, wherein the second portion of the water flushing apparatus extends from the quick connect/disconnect coupling to the first portion, wherein the second portion is distributed in a generally vertically elongated manner;
an elongated first connecting rod having a proximal end and distal end, an elongated second connecting rod having a proximal end and a distal end, the distal end of each connecting rod being operatively connected to the quick connect/disconnect coupling so as to permit manipulation, remotely at the distal end, of the quick connect/disconnect coupling between the locked and unlocked modes, whereby in the unlocked mode the flushing system can be retrieved as a unit from below ground by way of the connecting rods, wherein the proximal end of each connecting rod is operatively connected to a respective handle, wherein each handle is rotatably mounted on the water flushing apparatus,
wherein the flow control valve, the quick connect/disconnect coupling, the first and second connecting rods and the handles are located below ground, and
a below ground housing substantially enclosing the second portion of the water flushing apparatus, the flow control valve, the first and second connecting rods and the handles.
2. The system of claim 1 wherein at least one of the connecting rods includes a substantially straight portion and a bent proximal end, wherein the proximal end is bent from about 14 degrees to about 26 degrees relative to the substantially straight portion of the connecting rod.
3. The system of claim 1 wherein the quick connect/disconnect coupling is a cam lock.
4. The system of claim 3 wherein the quick connect/disconnect includes a male connector and a female connector, wherein the male connector is integral with the water distribution system and the female connector is integral with the water flushing apparatus.
5. The system of claim 4 wherein the female connector includes a pair of cam handles for selectively lockingly engaging the male connector, wherein the distal end of each connecting rod is operatively connected to a respective cam handle.
6. The system of claim 1 wherein the quick connect/disconnect coupling is located at a depth of at least 3 feet below the ground.
7. The system of claim 1 further including an above-ground housing at least partially enclosing the first portion of the water flushing apparatus.
8. The system of claim 7 further including a cap operatively positioned to redirect water exiting the outlet downwardly toward the ground and about the exterior of the above-ground housing.
9. The system of claim 7 further including a splash guard substantially at ground level and separating the above ground housing and the below ground housing, whereby erosion of the ground due to water exiting from the outlet is minimized.
10. The system of claim 1 wherein the first portion is configured such that the outlet is positioned downwardly toward the ground.
