The present invention relates to computer controlled hydro-positioners used for example in display fountains and systems thereof, such hydro-positioners configured for operation in a body of liquid, such as water in a natural or mar-made pond, lake and tank.
Water displays known as dancing fountains comprise a at least one, and often a plurality of nozzles for such fountains, which nozzles ire arranged in groups. Some such nozzles are rotatably mounted about a substantially vertical axis. It is customary in dancing fountains to vary the height of the water streams rhythmically where desired, as for example, in synchronization with music or musical effects. Disadvantageously, such vertical water height is often controlled by varying the pressure applied by a pump to a water flow.
What is desired is an apparatus, assembly and system operable to vary the height of the water streams from a central controller platform, using a precision ball valve wherein the mechanical components for effecting the ejection of water through a ball valve and nozzle from a pump/manifold are submersible and wherein the volume of the conduit through the ball of the ball valve is dynamically variable using computer based instructions. The invention provides such an apparatus, assembly and system.
The present invention is an apparatus, assembly and system that will produce one or a variety of vertical spray of different heights from a water fountain nozzle. The apparatus, assembly and system is operable to vary the height of the water streams using a central controller platform communicable coupled to a submersible housing having therein a servo controller and servo, the servo operable to dynamically rotate a ball in a ball valve, the ball having a conduit through which a stream of water is directed for ejection through a nozzle. The location of the ball in a certain position allows a high volume of water to traverse the conduit, a portion thereof to traverse the conduit and another portion to be blocked, or all of the stream of water to be blocked. A manifold having a pump coupled to an ingress thereof provides the source of pressurized water, and th egress of the manifold is coupled to the ball valve.
The mechanical components for effecting the ejection of water from the pump/manifold is submersible. The invention is an apparatus, assembly and system operable to vary the height of the water streams from a central controller platform, using a precision ball valve wherein the mechanical components for effecting the ejection of water through a ball valve and nozzle from a pump/manifold is submersible and wherein the volume of the conduit through the ball of the ball valve is dynamically variable. The apparatus, assembly and system of the present invention is operable to control the height of water spray from at least one, and often a plurality, of water fountain(s). A novel characteristic of the invention is submersible housing and components therein which are coupled to a controller to allow for the selective adjustability of the water flow supplying the nozzle(s). In a system of multiple nozzles, the water flow to one or a group of nozzles are controlled or adjusted independently of dial to the other groups of nozzles by using, per nozzle, a servo controller coupled to servo and thence to a ball in a ball valve as described herein.

A manifold 501 is coupled between an egress thereto and ingress 203 to the ball valve assembly 200. A pump 502 is coupled to an ingress 503 to the manifold 501. The pump can be located above the water or can be a submersible pump. The servo controller 408, servo motor 407 and a partial length of the servo shaft 406, are housed within a water or liquid impermeable, submersible housing 201. The servo shaft extends from the servo motor to outside the submersible housing and is coupled to the ball within the ball valve assembly. The controller includes a computer application program having an operating system and a communication protocol which comprise instructions stored on a computer readable medium operable to be executed by a microprocessor within tire controller. The servo controller is operable to execute a computer application program comprising instructions stored on a computer readable medium operable to be executed by a microprocessor within the servo controller to send signals to the servo motor. The controller and servo controller each comprise buffers, memories, registers and busses for receiving, holding, and sending control information. In an embodiment, the control signals from the servo controller to the servo motor comprise pulse width signals. Any number of fountain nozzles can utilize the invention to provide a multi-fountain display. One manifold and pump, for example, can feed a plurality of nozzles via the ball valve assembly. Further, one controller can send control signals to a plurality of hydro-controller assemblies.
More specifically, the invention comprises a controller having an input panel and operable to execute a computer application program such as an operating system and a communication protocol, such as Digital Multiplex (DMX). DMX is a standard for digital communication networks that are commonly used to control stage lighting and effects. It was originally intended as a standardized method for controlling light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It soon became the primary method for linking controllers (such as a lighting console) to dimmers and special effects devices such as fog machines and intelligent lights. DMX has also expanded to uses in non-theatrical interior and architectural lighting, at scales ranging from strings of Christmas lights to electronic billboards. DMX512 employs EIA-485 differential signaling at its physical layer, in conjunction with a variable-size, packet-based communication protocol. It is unidirectional.
Said controller is communicatively coupled to a submersible assembly. The submersible assembly is operable to located within a body of liquid, such as water in a natural or man-made pond, lake and tank. More specifically, the submersible assembly comprises a servo controller electrically coupled to the control panel via a communication protocol for transmitting and receiving control and power signals. The control signals are any suitable communication protocol, such as DMX or other control protocol. The power signals can be a DC power signal or an AC signal that is rectified via a transformer.
The servo controller is electrically coupled to a servo or stepper motor, operable to step clockwise or counterclockwise in steps or increments, for example, in 1.8 degree steps. Stepper motors enable accurate positioning of the motor shaft. Servo or stepper motors are used in various types of equipment for accurate rotation angle and speed control using pulse signals. Stepper motors also hold their position at stop, due to their mechanical design. Stepper motor and the associated servo controller consist of a driver which takes pulse signals in and converts them to motor motion and a stepper motor. Servos are controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM), through the control wire. The servo controller can be programmed using any suitable small device programming language. Exemplary servo controllers include but not are limited to those provided by Servotronix, Arduino, Adafruit and Raspberry Pi.
The servo motor is coupled to a ball within a ball valve assembly via a servo shaft. The ball valve is operable to open a conduit from the manifold through one of two egress ports, or partially through both egress ports. The servo shaft is operable to rotate the ball within the ball valve assembly so as to direct the flow of water from an ingress port into the ball valve and hence the ball therein, and out one or both of a first egress port 204 (display port) or second egress port 205 (exhaust port). The first ingress port can further be extended with a nozzle for directing the water spray. The ingress port of the ball valve assembly is coupled to a manifold 501 that provides a nearly constant pressure of water from a pump 502 coupled to the ingress of the manifold. The water, at nearly constant pressure via the adjustment of the ball within the ball valve, flows through the manifold and to the ingress port of the ball valve assembly.
The servo controller, servo motor and a partial length of the servo shaft, are housed within a water or liquid impermeable, submersible housing 201. The servo shaft extends from the servo motor to outside the submersible housing and is coupled to the ball within the ball valve assembly. When the ball valve is in a first position, water entering into the ball valve assembly, and thence the ball, from the manifold is directed by a conduit in the ball in the positive y-direction, thus ejecting the water skyward to a certain height dependent on, inter alia, the pressure of the water. When the ball valve is in a second position, water entering into the ball valve assembly and thence the ball, from the manifold is directed by the conduit in the ball in the negative y-direction, thus ejecting the water downward (exhaust). In any increment between the first position and the second position, water is partially ejected upward and partially ejected downward, thus varying the height of the spray. In a further embodiment, any suitable portion of the assembly, nozzle, or other component can be mounted on a platform to allow for the nozzle and hence the spray to be positioned at any direction from the vertical axis. The invention is still used to vary the height of the spray from such off-vertical direction.
