Definitions

  • the invention describes a water feature for generating a figurative spatial impression of any represented objects, formed from water and optically perceptible to the human observer, which results from the synopsis of the throwing heights of a plurality of water fountains.
  • Water games or fountains realized using fountains have been known for many centuries.
  • Technical solutions aimed at this are primarily concerned with optimizing the jet formation and direction, throw distance and arrangement of water fountains for water features.
  • the German utility model specification describes DE 20 2015 000 215 U1 "Water feature with a continuous flow of jets" means a device with which the association of a well-known object/symbol is intended to result for the viewer via a jet guide - which is fixed for each application - with the special, generated course of the emitted water jets, for example by a Christmas tree explicitly mentioned as an example, whose "trunk” is symbolized by a vertical tube with several openings on the shell side, from which water jets emerge, which in turn are to be perceived as “twigs”.
  • this technical solution has the disadvantage that due to the unchangeable position of the water outlet openings created during initial installation, only the same object can be represented symbolically, ie only a Christmas tree according to the example.
  • the font WO 2012/003951 A2 shows a multitude of perforated tiles in a frame. Below each tile is an electrically operated pump with a nozzle pointing vertically upwards. Even further below is a drip pan that essentially covers the entire area below the tiles. When operating this water feature, the pump sucks in water via a short suction pipe and sprays it in the form of a fountain in the area above the tiles. People can step on the tiles and let the "forest of fountains" sprinkle them.
  • a disadvantage of this device is that it is too complex and therefore expensive because of the three assembly levels - the tiles, the air gap with pumps and electric motors and the drip pan.
  • the invention is therefore based on the object of creating an improved water feature without such a hydromechanical restriction, which can represent any number of different spatial objects symbolized by water jets.
  • the core and aim of the invention is to convey a completely new type of visual Water play experience, which is characterized by the fact that the water fountains generated by the system according to the invention are not perceived by the human observer in isolation as individual fountains or water jets, but as a planar-spatial model outlined by the totality of the fountain tips, i.e. the reversal points of the water shooting up or three-dimensional object.
  • the invention is therefore based on the further feature of a maximum distance of 100 mm between the central axes of the jet nozzles installed on the fountain field and of 60 mm around a jet nozzle grouped lighting elements from the central axis of the jet nozzle, while according to the prior art due to the suitable pumping devices only being available in larger dimensions, only larger nozzle spacings were possible and also only available diameters of at least 300 mm are known for lighting rings intended for installation in connection with water feature jet nozzles .
  • the invention also differs very advantageously from the prior art in that the shape of the objects modeled with the fountain system can not only be chosen arbitrarily, but can also be constantly changed over time. Not only static spatial models can be presented, but also dynamically changing forms, so that a completely different new figure can emerge from a figure that has just been presented as a virtual body of water a few moments later. Correspondingly changing lighting moods can significantly intensify the impression of form when using the illuminated embodiment.
  • a three-dimensional landscape model can also be simulated from water, for example, the shape of which changes continuously in accordance with the route overflown, similar to a two-dimensional impression generated by a flight simulator.
  • an electrically driven and pressure-controlled pump 3 In the pumping device connected to a water supply ( 1 ) an electrically driven and pressure-controlled pump 3 generates the water pressure required to create a water fountain. After leaving the pump 3 , the water runs through a laminar flow generator 2 (which is not functionally necessary according to the invention) under controllable operating pressure and which prepares the flow of the water jet. Connected to the laminar flow generator 2 is at least one jet nozzle 1, from which the water fountain exits in the operating state.
  • the jet nozzle 1 can be installed either perpendicularly to the carrier element through a carrier element 5 preferably designed as a circuit board or, in a further embodiment, can be individually rotated and pivoted at an angle that deviates from the perpendicular to the carrier element 5 and can be adjusted.
  • At least one or more light-emitting elements 4 are arranged directly next to the jet nozzle 1 for illuminating the exiting water fountain. Due to their specific low sensitivity to moisture and their low energy consumption, light-emitting diodes (LED) and/or semiconductor lasers (laser diodes) in a single-color or multi-colored design are preferably considered as light-emitting elements.
  • LED light-emitting diodes
  • laser diodes semiconductor lasers
  • the lamp connections and the circuit board (carrier element 5 ) are filled with a watertight sealing compound in a manner known to those skilled in the art (not illustrated).
  • jet nozzle 1 depending on the intended use, various known to the person skilled in the art can also be rotated in the longitudinal axis and pivoted with a bend from it Versions are used to generate different jet shapes and to achieve variable throw distances of the exiting water fountain.
  • Jet nozzles that generate a strongly bundled, linear jet, (partial) circular jet nozzles that spread more widely or jet nozzles that generate a flat water film can also be used.
  • different types of jet nozzles can generate special effects or, for example, create desired turbulence with fountains from adjacent jet nozzles, primarily in statically operated fountain fields in which no ongoing change in shape of the symbolized water body is provided.
  • the appearance of a disordered, turbulent flow after the water has exited the jet nozzle which is undesirable for optical and energetic reasons, can be significantly reduced if the water has previously been deliberately placed in a laminar flow.
  • This purpose is served by the laminar flow generator 2, which directs the course of the flow through the use of a damping element and thereby considerably improves the flow behavior of the water after it emerges from the jet nozzle.
  • a metal mesh that is known to those skilled in the art and is designed for laminar flow optimization can be used as the damping element.
  • the use of the laminar flow generator results in a noticeable increase in the throwing distance of the fountain without any additional energy expenditure.
  • the pump field according to the invention ( 2 and 3 ) consists of the combination of any number of pumping devices ( 1 ) in any arrangement. one as in 2 and 3
  • the square arrangement of the pumping devices shown as an example is not required.
  • Several pump fields can also be combined in a modular manner.
  • a pump field is preferably installed horizontally so that the throwing direction of the emerging water fountains points vertically upwards with permanently installed jet nozzles.
  • the pump field can also be installed at an angle, particularly if the pumping devices are provided with swiveling jet nozzles and the water fountains are to be thrown in different directions in order to achieve special optical effects.
  • the pump field is watertight overall (protection class IP68 is technically feasible without further ado), which allows it to be used both above and below the water surface.
  • the pump control (not shown in the drawing) is carried out according to the invention by a suitable input and control unit (computer technology with corresponding control software), in that each pump device present in the pump field is controlled independently of the other pump devices belonging to the pump field via a suitable digital control protocol, which and event technology for controlling effect lighting is the established digital multiplex protocol (DMX) is individually controlled and regulated.
  • DMX digital multiplex protocol
  • the input and control unit for example a notebook with control software
  • Control signal generated and sent to a microcontroller, which contains at least one processor and has at least one suitable interface for the control protocol used for communication between the input and control unit and the pump field.
  • the microcontroller processes the control signal received from the input and control unit and uses D/A conversion or pulse width modulation (PWM) to generate one or more new signals to at least one downstream driver stage, which acts as a (e.g. MOSFET) output stage and in turn provides analog or PWM power supply and speed control for the pumping devices.
  • PWM pulse width modulation
  • the light in the illuminated further embodiment, can also be controlled via a (eg MOSFET) output stage in a similar way, in which case the power supply and brightness control can also be implemented via PWM in this case.
  • a (eg MOSFET) output stage in which case the power supply and brightness control can also be implemented via PWM in this case.
  • each of the light-emitting elements 4 can be controlled via additional channels of the bus system within the framework of the number of levels available according to the control protocol used in terms of brightness (0-100%) and color mixture (up to 16.8 million colors). be controlled and regulated in any degree.
  • a memory element for non-volatile storage of the control signals generated by the input and control unit and/or status information reported back by the pump field or its pump devices and possibly by the light-emitting elements.
  • An allocation table is stored in the storage element, which contains all of the commands transmitted by the input and control unit for the speed control of the pump devices and, in the case of the illuminated further embodiment, for the light control as well as the status information of the pump devices and the Contains lighting elements, insofar as they are technically designed and able to provide feedback on their status information.
  • the invention provides for the exchange of status information to be carried out bidirectionally via Remote Device Management (RDM).
  • RDM Remote Device Management
  • RDM also paves the way for manual or automatic (fine) calibration.
