A waterfall tank system is described for sheeting water onto a passing vehicle. The waterfall tank system includes a tank with a water supply inlet and a soap injector for injecting soap into the water flow to create a soap mix that is supplied to the tank. An air motor is included for providing air to an air manifold that is disposed within the tank. When air is introduced into the soap mix, bubbles are created. As the water, soap mix, and bubbles fill the tank, they fall from the tank via an overflow lip that creates a sheeting action, with the water, soap mix, and/or bubbles sheeting onto a vehicle passing below.

(1) Field of Invention
The present invention relates to a waterfall tank and, more particularly, to a waterfall and bubbler tank system for sheeting water and bubbles onto a passing vehicle.
(2) Description of Related Art
Vehicle washing systems have long been known in the art. By way of example, automatic vehicle-washing systems are well-known and are in widespread use for washing passenger automobiles, trucks, buses, railroad equipment, and the like. A typical system includes a conveyor for moving the vehicle through the installation, and a series of power-driven brushes which are moved around the vehicle under a drenching spray of water and soap or detergent to remove dirt and grease. The washed vehicle is given a spray of clean rinse water, and is then moved to a drying station.
While such drenching spray systems are operable for introducing soap and water to a passing vehicle, they require multiple spray heads, each of which is prone to breakage and maintenance. Additionally, typical spray heads introduce a low volume to the passing vehicle and, therefore, are operated under high pressure to be effective. Further, due to the pumps that are required to operate such spray systems, traditional drenching spray systems utilize a lot of electricity and are otherwise not environmentally sensitive. Finally, spray systems do not evenly distribute the solution as any distribution is largely limited to the location and reach of the spray heads.
Thus, a continuing need exists for an environmentally sensitive system for introducing a relatively large volume of soap and water to a passing vehicle without the need for multiple, high-pressure spray heads.
While considering the failure of others to make and/or use all of the above factors/ingredients/steps/components in this technology space, the inventor unexpectedly realized that a waterfall tank system can be employed to introduce a large volume of water, soap, and bubbles to a passing vehicle through a sheeting effect without the need for multiple high-pressure spray heads. Additionally, the use of a sheeting effect provides for an even distribution of water, etc., to the passing vehicle.
Thus, the present invention is a waterfall tank system for sheeting water onto a passing vehicle. The system includes a tank having a trough portion and an overflow lip that is at least as wide as a passing vehicle. A support system is connected with the tank for elevating the tank above a ground surface to allow a vehicle to pass beneath the tank. Additionally, a water supply inlet is fluidly connected with the trough portion of the tank for receiving a water flow from an external water source and introducing water into the tank. Upon receiving water, the trough portion collects the water until the water reaches the overflow lip, at which point the water flows over the overflow lip and sheets from the tank onto a passing vehicle.
To provide soap and bubbles to the system, a soap injector is fluidly connected with the water supply inlet for injecting soap into the water flow to create a soap mix that is supplied to the tank. Additionally, a perforated air manifold is positioned in the trough portion of the tank, with an air motor fluidly connected with the perforated air manifold. An example of such an air manifold is an elongated pipe with a top half and a bottom half, with two rows of holes formed along the top half while a single row of holes are formed along the bottom half. The air motor is used to introduce air through the perforated air manifold and into the soap mix. Thus, upon receiving the soap mix and air, bubbles are created that fill the tank until reaching the overflow lip, at which point the bubbles and soap mix (and water) flow over the overflow lip and onto the passing vehicle.
To control the volume of the water, soap, bubbles, and/or soap mix within the tank, a mechanical float valve is operably connected with the water supply inlet to close upon the volume exceeding a predetermined level within the tank and to open upon the volume falling below the predetermined level.
In some circumstances, it may be desirable to direct the flow of the water. In this aspect, a flow director is connected with the overflow lip to direct water flowing over the overflow lip. An example of such a flow director includes a first pivoting arm and a second pivoting arm. Each of the pivoting arms are pivotally connected with the overflow lip such that they can independently reside on the overflow lip to narrow a width of flow of water flowing over the overflow lip or pivot way from the overflow lip to increase the width of flow of water flowing over the overflow lip.
The sheeting effect described above can, in some cases, be disturbed due to air turbulence. To mitigate such disturbance, a curtain is attached with the tank such that it hangs from the tank proximate the overflow lip. The curtain operates to block the air turbulence from affecting the water as it flows from the overflow lip to create the sheeting effect.
Finally, as can be appreciated by one in the art, the present invention also comprises a method for forming and using the waterfall tank system described herein. The method comprises a plurality of acts of forming and operating the waterfall tank system.

(1) Description
As shown in
In this aspect, the waterfall tank system 100 includes a tank 102 having a trough portion 104 and an overflow lip 106. The trough portion 104 acts as a trough to collect water that is introduced into the tank 102 from a water supply inlet 108. The water supply inlet 108 is fluidly connected (e.g., via piping) with the trough portion 104. In operation, the water supply inlet 108 receives water from an external water source and introduces the water into the tank 102 where it gathers in the trough portion 104. It should be understood that although the system as described uses water, the present invention is not intended to be limited thereto as it can be used with any fluid and/or fluid source. Thus, the water supply inlet 108 is, in its broadest form, a fluid supply inlet, with water being but one non-limiting example.
Upon receiving water, the trough portion 104 collects the water until the water level reaches the overflow lip 106, at which point the water flows over the overflow lip 106 and sheets from the tank 102 onto a passing vehicle (as depicted in
In addition to providing water onto a passing vehicle, the present invention provides soap and bubbles to said vehicle. As depicted in
To create bubbles (e.g., soap bubbles), an air manifold 112 is positioned in the trough portion 104 of the tank 102. An air motor 114 is fluidly connected with the air manifold 112 to introduce air through the air manifold 112 and into the soap mix. The air motor 114 is any suitable mechanism or device that is operable for pumping air, a non-limiting example of which includes a 1.5 horse power (HP), 120 Volt Alternating Current (VAC) electric air motor. Upon receiving the soap mix and air, bubbles are created that fill the tank 102 until reaching the overflow lip 106, at which point the bubbles and soap mix flow over the overflow lip 106 and onto a passing vehicle (as depicted in
Referring again to the air manifold 112, the manifold is any suitable mechanism or device that is operable for receiving air and distributing the air into a fluid (e.g., soap mix), a non-limiting example of which includes a two-inch polyvinyl chloride (PVC) pipe. The air manifold 112 is perforated to allow air that is introduced into the manifold 112 from the air motor 114 to escape into the soap mix. As a non-limiting example, the perforated air manifold 112 is an elongated pipe manifold with a top half and a bottom half, with two rows of holes formed along the top half and a single row of holes formed along the bottom half (e.g., facing downward).
To control the amount of water and soap (and the corresponding soap mix) that is introduced to the tank, a volume control valve 116 is operably connected with the water supply. As a non-limiting example, the volume control valve 116 is a mechanical float valve that is operably connected with water supply inlet to close upon the soap mix exceeding a predetermined level within the tank and to open upon the soap mix falling below the predetermined level.
In operation, as bubbles flow from the overflow lip 106, they fall onto a passing car. However, wind and other air turbulence can sometimes affect the fall of the bubbles. As such, a curtain 118 is attached with the tank 102 to block such air turbulence and prevent the falling bubbles from blowing uncontrollably away from a car surface. For example, the curtain 118 hangs from the tank 102 proximate the overflow lip 106 is formed of any suitably durable and semi-rigid material, a non-limiting example of which includes vinyl. Thus, the curtain 118 allows the bubbles to freely fall, yet blocks wind and other air turbulence.
As noted above, wind and other air turbulence can sometimes affect the fall of the bubbles. Such turbulence can also have an effect on the sheeting of the water that falls from the tank 102. To control the sheeting effect of the water, a flow director 119 can be connected with the overflow lip 106 to direct water that is flowing over the overflow lip 106. The flow director 119 is any suitable mechanism or device that is capable of directing the flow from the overflow lip 106, a non-limiting example of which includes a pair of pivoting arms. For example, a first pivoting arm 119A and a second pivoting arm 119B are pivotally connected with the overflow lip 106 such that they can independently reside on the overflow lip 106 to narrow a width of flow of water flowing over the overflow lip 106. Alternatively, each of the pivoting arms 119A and 119B can pivot away from the overflow lip 106 to increase the width of flow of water (and bubbles, soap mix, etc.) flowing over the overflow lip 106. In other words, the pivoting arms 119A and 119B operate to alter the flow of water by decreasing or increasing the width of the overflow lip 106 (or at least the portion of the overflow lip 106 from which the water can escape and flow)
By narrowing the portion of the overflow lip 106 from which water escapes, the thickness or depth of the water is increased (due the volume of water remaining relatively constant). As such, the sheet of water that now falls from the overflow lip 106 is thicker and less susceptible to air turbulence.
Alternatively, in a situation of low air turbulence, it may be desirable to pivot the pivoting arms 119A and 119B away from the overflow lip 106 to maximize the width of the overflow lip 106 (or the portion of the overflow lip 106 from which water escapes) and, thereby, the width of sheeting water. In this example, the depth of water that flows over the overflow lip 106 is thinner (than the circumstance described above), which creates a thinner, yet wider, sheet of water.
Additionally, a lid 120 is attached with the tank 102 to cover the tank 102 yet allow selective access thereto. For example, the lid 120 is pivotally connected with the tank 102 via hinges 122 or any other suitable connection.
For further understanding,
Additionally,
Pivoting arms 119A and 119B are shown residing on top of the overflow lip 106. As can be appreciated by one skilled in the art and as described above, the flow director (e.g., pivoting arms 119A and 119B) is used to alter the width 400 of the flow that flows over the overflow lip 106. Such width 400 control can be used to manage the thickness (or depth) of the sheet of water that falls from the tank 102.
