Description

FIELD OF THE INVENTION

This disclosure relates generally to a fluid delivery system and more particularly to an apparatus for mounting a pressure switch/control box remotely from the fluid delivery system.

BACKGROUND OF THE INVENTION

Referring to FIG. 1, a typical well water system 100 for a building 102 in accordance with the prior art is shown. Typically, well water is drawn from a water source 104 located below the surface of the earth and stored in a storage tank 106 located close to or within the building 102. A pumping device 108 disposed between the water source 104 (which may be a well or a storage tank in the building) and the storage tank 106 is used to draw water from the water source 104 and deposit the water within the storage tank 106 for later use. The storage tank 106 is typically located within the cellar of the building 102 and may be connected to various points within the building 102 (e.g. faucets) from which water can be drawn as needed. As the stored water is drawn from the storage tank 106, the volume of the water within the tank 106 decreases and when the volume of water within the tank 106 has reached a predetermined volume or level, the pumping device 108 is operated to draw water from the well to replace the water that was drawn from the storage tank 106. The volume of the water in the storage tank 106 is thus monitored via a storage tank monitoring device 110 so that the pumping device 108 ‘knows’ when to begin replenishing the water being drawn from the storage tank 106. When the water within the storage tank 106 needs to be replenished, the pumping device 106 is turned on to pump water from the water source 104.
The pumping device 108 is electrically communicated with a power source 112 via a pump switching or control device 114 and is turned on and off via the pump control device 114. The pump control device 114 typically includes or is disposed within close proximity to the storage tank monitoring device 110. As the volume of water in the storage tank 106 falls depending on the water requirements of the building, the pump control device 114 turns the pumping device 108 on to draw more water from the water source 104 for storage in the storage tank 106. As the volume of water in the storage tank 106 increases to a predetermined level, the pump control device 114 turns the pumping device 108 off to stop drawing water from the water source 104. Thus, as water is being called by the building 102, the pumping device 108 is being cycled on and off to maintain a desired water volume within the storage tank 106.
Unfortunately, the pump control device 114, which is an electromechanical switching device, is typically disposed in close proximity to the outlet 116 of the storage tank 106 which is usually located near the bottom of the storage tank 106 in close proximity to the floor 117 of the cellar or basement. This is undesirable for several reasons. First, because a large number of basements are ‘wet’ basements, water accumulates on the floor of the cellar during wet seasons. And in some cases, these areas may become flooded causing the pump control device 114 to be exposed to or even disposed within water contained with the cellar. This can cause the components of the pump control device 114 to short circuit, become damaged and/or cease operating altogether. Thus, even if the pumping device 108 is a submersible-type device (i.e. able to operate under water), the pumping device 108 may not be able to operate because the control device 114 (which is typically not water-proof) may be damaged due to exposure to water.
Second, because the storage tank 106, storage tank monitoring device 110 and pump control device 114 are typically located out of the way and in space limited areas, it is usually very difficult and inconvenient to access and work on the pump control device 114 when needed. As the pump control device 114 is an electrical device, this limited accessibility can be a safety hazard to individuals working on the system 100. Third, because the pump control device 114, which is usually only covered by a non-sealed plastic cover that is easily removed by hand or via a screwdriver, are located close to the floor 117 of the basement, it is also easily accessible to children. And because there is electrical power running from the power source 112 to the device 114, this is extremely unsafe and can expose children or animals to electrocution.

DETAILED DESCRIPTION

As referred to herein, the pump control device 212 may include any control or switching device used to start or stop the flow of fluid. As such, the terms control and switch may be used interchangeably herein.
Referring to FIG. 2, a first embodiment of a pump control system 200 for a building 102 is shown in accordance with the present invention and includes a water reservoir 104 in flow communication with a water storage tank 106 (or a water treatment device) and a pumping device 108. The pump control system 200 includes a monitoring device 210 associated with the storage tank 106 to monitor the level or pressure of the water contained within the storage tank 106. Although the monitoring device 210 is shown as being located in proximity to the storage tank outlet 116, the monitoring device 210 may be located at any point suitable to the desired end purpose, such as being located within or integrated with the storage tank 106, so long as the monitoring device 210 is able to accurately monitor the level or pressure of the water contained with the tank 106.
The pump control system 200 further includes a pump control device 212 that may be securely mounted to a support structure 214 via a device mounting apparatus 216, wherein the device mounting apparatus 216 may be securely associated with the support structure 214 via any securing means suitable to the desired end purpose, such as screws, bolts, clips and/or adhesive. Similarly, the pump control device 212 may be securely associated with the device mounting apparatus 216 via any securing means suitable to the desired end purpose, such as screws, bolts, clips and/or adhesive. An adapter interface device 218 is provided and is associated with the pump control device 212 and the monitoring device 210 to allow communication between the pump control device 212 and the monitoring device 210.
As shown in FIG. 2, the adapter interface device 218 is directly associated with the pump control device 212 and is associated with the monitoring device 210 via an interface link 215. Interface link 215 may be any communications link suitable to the desired end purpose, such as a wireless connection, an electrical connection and/or a mechanical connection (such as a pressure tube and/or a configurable mechanical linkage). This allows the monitoring device 210 to communicate the level and/or pressure of the water contained within the storage tank 106 to the pump control device 212. The pump control device 212 may also be in electrical communication with both the power source 112 and the pumping device 108 and may be controllably configurable to cycle the power to the pumping device 108 on and off in order to be able to turn the pumping device 108 on and off as needed. Referring to FIG. 3 and FIG. 4, the pump control device 212 is shown as being securingly mounted to a support structure 214 via a support device 216 and a means for associating the pump control device 212 to the support device 216. It should be appreciated that the interface link 215 is shown as being several feet in length to allow the pump control device 212 to be located away from the floor 117 of the building 102 and preferably at higher levels away from the reach of children.
In accordance with the present invention and referring again to FIG. 2, the pump control system 200 operates as follows. As water is called from various locations within the building 102, the water contained within the water storage tank 106 flows out of the storage tank outlet 116 to the required destination. This causes the level of water contained with the storage tank 106 to decrease thus causing the pressure within the tank 106 to decrease. This decrease in pressure is sensed by the monitoring device 210 which sends a signal responsive to the pressure level to the pump control device 212 via the interface link 215 and the interface device 218. When the pressure drops to a predetermined level, the pump control device 212 directs power from the power source 112 to the pumping device 108, causing the pumping device 108 to switch on to draw water from the water source 104 into the water storage tank 106. As the water in the water storage tank 106 increases, a corresponding increase in the pressure within the water storage tank 106 occurs. This increase in pressure is sensed by the monitoring device 210 which again sends a signal responsive to the pressure level to the pump control device 212 via the interface link 215 and the interface device 218. When the pressure increases to a predetermined level, the pump control device 212 disables the power flow between the power source 112 and the pumping device 108, causing the pumping device 108 to shut off and stop drawing water from the water source 104.
Referring to FIGS. 5A-5D, the pump control device 212 is shown being associated with the support structure 214 via the device mounting apparatus 216, in accordance with one embodiment. Also, in accordance with an embodiment of the invention, the adapter interface device 218 is a device that receives/generates a signal (via pressure, electrical or mechanical means) and communicates this signal to the pump control device 212. For example, the adapter interface device 218 may be identical to the monitoring device 210 connected to the monitoring device 210 via a pressure tube 215. This allows the pump control device 212 to sense the pressure at the storage tank outlet 116 and act accordingly. As another example, the adapter interface device 218 may be connected to the monitoring device 210 via a wire connection 215. In this embodiment, the monitoring device 210 may sense the pressure at the storage tank outlet 116, generate an electrical signal responsive to that pressure and communicate that electrical signal to the pump control device 212 via an electrical connection, such as a wire 215. The pump control device 212 may then act responsive to the electrical signal. It is also contemplated that the pump control device 212 may be configured to control operation of the pumping device 108 via any configuration suitable to the desired end purpose. For example, the pump control device 212 may be configured to control power to the pumping device 108 at the power source 112 or the pump control device 212 may be configured to control power to the pumping device 108 at the pumping device 108 or the pump control device 212 may be configured to control operation of the pumping device 108 via control logic at the pumping device 108.
Referring to FIG. 6, a second embodiment of a pump control system 300 for a building 102 is shown in accordance with the present invention and includes a water reservoir 104 in flow communication with a pressure tank 302 and a pumping device 108 via a flow pipe 105. The pump control system 300 includes a monitoring device 210 associated with the flow pipe 105 to monitor the pressure of the flow within the flow pipe 105. Although the monitoring device 210 is shown as being located in proximity to the pressure tank outlet 304, the monitoring device 210 may be located at any point suitable to the desired end purpose, such as being located within or integrated with the pressure tank 302, so long as the monitoring device 210 is able to accurately monitor the pressure of the flow within the flow pipe 105.
The pump control system 300 further includes a pump control device 212 having a pump control interface device 218, wherein the pump control interface device 218 is in signal communication with the pump control device 212 and the monitoring device 210 via an interface link 215. This allows the monitoring device 210 to communicate the pressure of the flow within the flow pipe 105 to the pump control device 212. The pump control device 212 is also in electrical communication with both the power source 112 and the pumping device 108 and configured to be able to cycle the power to the pumping device 108 on and/or off in order to turn the pumping device 108 on/off as needed. Thus, the pump control device 212 can control the pumping device 108 responsive to the pressure within the flow pipe 105.
It should be appreciated that while the present invention has been described herein in terms of a building water system, the pump control system 200, 300 of the present invention may be used for any fluid system that has electronic controls located in an area that exposes the controls to moisture or access by children. Additionally, although the invention is discussed herein in terms of sensing pressure of a fluid, the invention may be practiced relative to any other suitable characteristic, such as fluid flow rate and/or fluid volume.
