The present invention relates to the field of water display.

At the EPCOT Center at Disney World, Florida, there is a water display known as the Leapfrog fountain with laminar flow nozzles. Such a water display is characterized in that a plurality of laminar flow nozzles are arranged to be spaced apart at irregular intervals across a certain area. At each nozzle position, the laminar flow nozzle ejects the laminar flow stream toward the adjacent laminar flow nozzle position. A drainage section is also provided adjacent each laminar flow nozzle location to minimize splashes from laminar flow entering the drainage section and to recover water for continued use. Therefore, each nozzle uses an arch of constant height and width, so that an arcuate laminar flow jetting to each nozzle can be directed to the drainage portion of the adjacent nozzles. By placing two blow nozzles at each nozzle position, the laminar flow classification can be directed in the desired direction in either direction. By controlling the classification, the leaf log display can be shaped like a sea snake, so that in fact, a single length of classification erupts at the bottom, arcs to the ground on another floor, and eventually appears to disappear into the bottom.

By properly adjusting the laminar flow classification, these fractions can all form their own properties, providing fun for children and adults. This was developed by the inventor of the present invention for Disney. As a result, the assignee of the present invention has installed this general type of fountain in various parts of the world, especially under a contract with Disney.

It is an object of the present invention to extend the use of laminar flow nozzles through a new and different water display that provides unique sights for day and night atmospheres.

The present invention discloses a water display using laminar flow classification to make a dynamic arched display. The laminar flow nozzle is mounted on an assembly for changing the angle and repositioning the laminar flow nozzle, so that the laminar flow is ejected at different angles from a certain position, which changes the characteristics of the display in a dynamic manner. By controlling the pressure of the water to be supplied and controlling the nozzle position and angle at the same time, the classification can be changed so that a dynamic display is formed while returning the classification to a constant position irrespective of the height of the water classification. Illuminating the laminar flow from the inside, the neon tube with the supplied color and the distillation distillation are illuminated. Intersecting the laminar flow provides interesting water formation, by intersecting two classifications of different colors, producing a third color in the flare portion of the intersection. Features of the invention may be used in combination, or all independently, on the same device as desired.

Referring first to Figure 1, one embodiment of the present invention is illustrated. In this embodiment, the laminar flow nozzle, generally indicated by reference numeral 20, is located below the floor level, and the laminar flow classification 22 is ejected upward in an arcuate direction to bend toward the "drainage" region, generally indicated by reference numeral 24. The drainage zone receives the laminar flow as minimally as possible and receives the water through the outlet 26 for filtration and reuse in the system. Drainage area 24 may take many forms, such as a suitable screen on which small rocks are supported to provide natural progression, and the classification may be accommodated in any manner desired. As shown in FIG. 1, in the above embodiment, a plurality of arcuate classifications 22 may be provided to form a cover shape for use at the entrance of a place such as a shopping center.

Detailed examples of the laminar flow nozzles used in the present invention are shown in FIGS. 8 and 9. The nozzle is characterized in that the cylindrical enclosure 28 has a water inlet 30 adjacent its bottom to supply pressurized water to the enclosure 28.

To provide a relatively small plurality of flow passages, there is a member 30 above the water inlet that, for example, goes straight into the stream, such as a rigid, open cell foam and reduces turbulence. Above it is a plenum 32 below the exit orifice 34 atop the cover 36 of the enclosure. The outlet orifice is a sharp orifice to provide a small viscous pull to the laminar flow classification 22 ejected there. Thus, the flow in fraction 22 is not only a laminar flow, but a slug that is highly preferred for the present invention. Laminar flow is a parallel flow of local streamlines. This is compared to turbulence, where the streamline of turbulence crosses each other and fluid mixing occurs in the flow. In the case of laminar flow fully deployed into the tube, this flow characteristic is essentially a parabola with the maximum velocity at the center of the tube, which is reduced along the radius by viscous towing, resulting in zero velocity at the wall of the tube. do. Slugs, on the other hand, are not only streams with local streamlines parallel to each other, but also the flow of all the streamlines across the cross section of the flow plane. The slugs are generated by the laminar flow nozzles of FIGS. 8 and 9, which occur as a result of the sharp edge orifices 34 which do not have any significant area in contact with the high velocity jet 22. Complete laminar flow and complete slugs cannot be achieved, but can be close to these. However, as described in more detail below, the dynamic effects in the various embodiments of the present invention are enhanced by the slugs, so slugs in which better laminar flow typically occurs are preferred in the present invention.

2 to 7, the suspension of the laminar flow nozzle of the present invention is shown in detail. The base, consisting of parallel base members 38, to which the horizontal member 40 is welded and spaced apart by the horizontal member 40, is provided with a flange 42 thereon to fasten the assembly to the desired installation position. . A pair of upright members 44 are firmly welded to the base adjacent one end thereof, and a pair of inclined members 46 are welded to the base to form a triangular structure with the base as viewed from the side. A structure composed of parallel members 50 spaced apart by the rod members 52 as shown in FIG. 4, a view along line 4-4 of FIG. These rod end bearings support the shaft 54 which extends while supporting on both ends (FIGS. 3 and 5). In general, additional rod end bearings 56 for supporting the laminar flow nozzle on the shaft-shaped protrusion 60 connected to the laminar flow nozzle indicated by the reference numeral 58 are fastened to the upper end of the member 50 (see FIG. 2). . Preferably, the laminar flow nozzle is supported approximately at the center of gravity so as to rotate freely in the rod end bearing 56 without actual imbalance. A counterweight 61, which is a rigid metal weight body, is installed at the opposite end of the balancing member 50 to balance the boom of the laminar flow nozzle 58 with respect to the axis defined by the shaft 54 and the rod end bearing 48 (fourth). See also).

The wheel-shaped member 62 is firmly fastened to the member 46 (see FIGS. 3, 5 and 6), and the wheel-shaped member is provided with a gap with one of the crocus members 52. Remove portion 64 to have. The wheel 66, which is firmly fastened to the nozzle 58, is also installed on the same plane as the wheel-shaped member 62, and with this bearing about the axis of the rod end bearing 56 of the wheel 66. Let the laminar flow nozzle 58 rotate. The wheel-shaped member 62 and the wheel 66 fix one end 70 to the wheel-shaped member 62, as shown in the figure, around the wheel 66 and around the wheel-shaped member 62. Fastened by means of a stainless steel belt 68 wound clockwise with an adjustment anchor 72 that pulls a spring 74 extending between the anchor and the stainless steel belt 68 to provide the belt with the desired tension. It can be fixed by. That is, the rotation of the parallel member 50 moves the belt 68 and the movement of the belt 68 rotates the wheel 66 and the nozzle 58. Therefore, the belt 68 converts the movement of the pneumatic cylinder 80 into the rotational movement of the laminar flow nozzle 58. Here, the direction of rotation of the parallel member 50 and the direction of rotation of the laminar flow nozzle 58 itself by the action of the belt 68 become opposite directions. This is because the wheel-shaped member 62 is a non-rotatable member fixed to the member 46 so that the rotation of the parallel member 50 relatively opposes the wheel-shaped member 62 in the direction of rotation of the parallel member 50. This is because the same effect as rotated in the direction. The ratio of the rotation angle of the parallel member 50 and the rotation angle of the laminar flow nozzle 58 body depends on the diameter ratio of the wheel 66 and the wheel-shaped member 62. This belt securely holds the wheel 66 by the clamp bolt 76 which securely tightens the belt to the wheel 66 in the clamp position, thereby preventing slipping against the wheel 66.

In the above arrangement, this assembly, which has a laminar flow nozzle 58 at one end and a counterweight 61 at the other end, is a balanced assembly that rotates about an axis 54 with a suitable angle freedom. 66 and the wheel-shaped member 62 have the same diameter, and the laminar flow nozzle 58 rotates in an arc but does not rotate at all with respect to the center of gravity, so that the original position of the laminar flow classification is changed. It does not change the angle. By making the wheel 66 smaller than the wheel-shaped member 62, rotating the entire structure about the axis 54 axis causes the laminar flow nozzle to rotate about its center of gravity by the effect of the belt 68. . This is illustrated in FIG. 6, in which the assembly in which the laminar flow nozzle is installed rotates clockwise about the axis 54, and the laminar flow nozzle rotates counterclockwise relative to the fixed base. do. Therefore, as shown in FIG. 6, the laminar flow 22, which is illustrated as ejecting from the laminar flow nozzles at two specific locations of the assembly, is placed on the nozzle according to the relative size of the wheel 66 and the wheel-shaped member 62. FIG. It will pass through a point in space (78: intersection of classifications) in which it is located. For different relative positions of the assembly, the laminar flow 22 has different angles, but still passes through the point 78, so if the point 78 is placed at the bottom level, the laminar flow is controlled by the position control of the assembly. Although it appears to be ejecting from a fixed position, it can be at any angle.

In order to control the assembly, an air cylinder 80 is formed between one of the horizontal members 40 on the fixed frame assembly and the pin 82 passing through the U-shaped connector member 84 welded to the cross bars 52 of the rotating assembly. (See FIG. 4), the axis of the pin 82 is effectively below the axis 54 of the axis on which the assembly rotates. As the pneumatic cylinder is extended, the assembly rotates counterclockwise and reverses. ) Is also the same. These various parts mentioned above are shown in FIG. 7, taken along line 7-7 of FIG.

Control of the system is shown schematically in FIG. In particular, a computer, typically an IBM PC or PC-combined computer 86, controls the pressure of the water supplied to the clear stream nozzle 58 by the pump 88 by an appropriate controller 90. Similarly, the supply to the pneumatic cylinder 80 by the pump 92 is controlled by the controller 94. In general, these controls may be any type of control known in the art for this purpose. Through a specific embodiment, the pump to the laminar flow nozzle, for control of the water going to the laminar flow nozzle, is based on the pressure required for the laminar flow nozzle enclosure or based on the pressure measured at a representative point of the supply line to the laminar flow nozzle. Control the flow of water. Optionally, the water flow can be controlled to provide the desired pressure and pressure characteristics, which is limited in the line to pump water, and then by dumping the amount to be dumped at any time selected to provide the desired hydraulic pressure control to the distillation nozzle. Consists of draining a part. It is possible to control the pump 88 itself to generate different pressures, but this is usually more difficult than operating the pump at the same power level or controlling the water flow. Similarly, when controlling the pneumatic cylinder 8 Position feedback using position feedback to allow the control device 94 to act on the difference between the command position of the computer 86 and the actual position of the pneumatic cylinder or, alternatively, to return the pneumatic cylinder to its known position frequently. In the absence of this, long-term drift of the pneumatic cylinder caused by inaccurate control can be avoided. In this respect, for this purpose, a turnbuckle type regulator 96 (FIG. 7) is provided for the engagement between the pneumatic cylinder 80 and the rotary assembly to provide a known pneumatic cylinder position and the desired equivalent laminar flow classification. You can manually adjust the orientation to match.

Referring to FIG. 10, the advantages and effects of the above-mentioned structure can be seen. As shown, the nozzle assembly, generally designated as 20, causes the laminar flow 22 to be ejected upwards, curved above and proceeding to the lower drain, generally designated 24. The laminar flow 22 may exhibit an irregular shape by merely changing the pressure of the water supplied to the laminar flow nozzle, while the classification falls around the drainage area 24 depending on how the pressure in the laminar flow nozzle changes, and sometimes falls short of it. It also falls over. However, by controlling both the pressure and the angle of the jet in the laminar flow nozzle, the laminar flow fraction 22 is continuously provided in the drain 24 without being found and provided in the shape shown in FIG. This can be visualized as follows:

Referring to FIG. 1, the laminar flow classification 22 generally represents a parabola starting from the laminar flow nozzle, indicated by reference numeral 20, and ending at the drain 24. As shown in FIG. However, the arch shown is only one of a continuous family of arches ejected from the laminar flow nozzle 20 and ending at the drain 24, and through the above mentioned device the angle of the laminar flow nozzle By adjusting the water pressure, it is possible to form a higher or lower arch as desired so that this classification can be spread out as desired to reach the drain. In this regard, the relationship between the pressure and the laminar flow angle, or, optionally, the position of the device controlled by the pneumatic cylinder 80 can be calculated. Preferably, the arch formed and angled to terminate at the drain 24 create a look up table for use in the computer 86 controlling the system using empirical measurements obtained by adjusting the pressure. Can be. Due to the effect of slugs, the basic design of each water fractionation is a laminar flow nozzle because no water exchange occurs with adjacent fractions forming different trajectories due to the same housing across the stream diameter of the slugs. It is very similar to an independent projectile starting from and following its own trajectory towards the drain, so that it is relatively unaffected by the fraction that precedes or follows the fraction. For this reason, slugs are preferred in the present invention, and laminar flow, which develops faster in the central part, causes such water exchange to take place, especially in the dynamic sorting as illustrated in FIG. 10. torsion of rodlike characteristics occurs.

Therefore, in view of the above description, the point 96 of the fraction 22 appears to have been ejected from the laminar flow nozzle at a pressure and angle corresponding to the virtually shown arch 98 having a relatively high pressure and a high angle. The portion 100 of the laminar flow classification not far from the point 96 is on the lower arch 102, such as the points 104 and 106, corresponding to the shallower angle, the jet of the lower laminar flow nozzle pressure. see. Point 96, of course, continues along orbit 98, and points 100, 104, 106, of course, also along orbit 102, all of which enter the drain 24, which is actually the same place. . Of course, the flow portion following the middle track will continue to follow this middle track until they also enter drain 24, which is the same place. Therefore, for a given range of change in classification angle, the amount of "wiggle" in the classification increases until it reaches the top of the orbit, and the tenth degree knows that the classification decreases to zero as it enters the drain. Can be. However, this is not limited to the instantaneous shape such as the shape shown in FIG. Because the shape of the different parts at any moment represents the fraction of water jetted at different times, it can instantaneously show a larger change in fractionation angle in the rise and fall of the fraction than the top of the orbit.

Other features of the invention are illustrated in FIGS. 6, 8, and 9. In particular, with reference to FIGS. 8 and 9, the optical fiber bundles are connected through the walls of the laminar flow nozzles 58, which are coaxially coaxial with the laminar flow sorter 22 and upwardly through the flow straight member 30. It extends and its upper end 110 is supposed to terminate about below the exit orifice 34 of the laminar flow nozzle. Therefore, the light connected to the optical fiber bundle is irradiated along the laminar flow classification 22 which itself acts as one large light pipe. In particular, since the light emitted from the ends of the sugar fiber bundles has a finite angular scattering, and the laminar flow 22 has a soft glass rod outer surface, the light reflected by the water-air interface is reflected from the water-air interface. Repeated reflections will cause continuous laminar flow. For reasons such as laminar flow is not complete, curved, etc., some of the light in the entire long stream will have an angle of incidence that is too large to reflect to the water-air interface and will "leak" through the surface of the resulting stream. This appears as the final effect of the laminar sorting along the way of the colored laminar class depending on the color of the light supplied, thus representing a fairly unusual and fascinating nighttime display. As shown in FIG. 6, the color wheel 112 may provide a continuous discoloration of the color classification or optionally command a color change as part of choreography of the laminar flow classification with concurrency with the motion of the laminar flow classification. Or, if desired, controlled by the computer 86 to synchronize the color and movement of the classification with other shapes, such as music.

Referring to FIG. 11, there is shown another form of display that can be achieved by the present invention. Here, the two laminar flow nozzles 20 jet laminar flow classifications 22a and 22b upward from the opposite ends of the same arch to fan out at the top portion 116. By providing two laminar flow nozzles with water of equal pressure and controlling the direction of the laminar flow nozzles to coincide, the laminar flow 22 can move upward and downward or symmetrically meander as shown in FIG. This may cause the fan-shaped portion 116 to move up and down. In this embodiment, an interesting movement can be achieved by changing only the pressure, or by changing only the angles of both classes, or by changing both the pressure and the angle. By simultaneously changing the pressure angle and position of the nozzle, these jets can be ejected from two points and passed through two fixed points spatially, as if each jet is hung at one of each point and orbit Irrespective of By illuminating the two laminar flow classifications with different colored lights, the laminar flow classification 22a is illuminated in red, and the laminar flow classification 22b is illuminated in green, as shown in the embodiment shown in FIG. The classification produces light of each color, but in fan portion 116, the colors are mixed to form a yellow fan shape portion. In some cases, the fan-shaped portion 116 may actually occur on one side of the center of the display rather than in the center, as shown in FIG. 11 so that the curvature may form a kind of mushroom shape under the influence of gravity. . In any case, due to the slit flow of the laminar flow classification, the fan-shaped part (except when the surface tension is far enough from the point of collision of the fan-shape to break the fan-like part into small droplets around the fan-shaped outer periphery) ( It should be noted that the flow in 116 represents a relatively good condition.

In some cases, desirable results can be obtained by varying the pressure of the water in the laminar flow nozzle without changing the elevation direction of the nozzle in a complementary manner. This results in an interesting and time-dependent laminar flow classification as intended. When a fraction of the fraction is ejected through the nozzle orifice, the fraction of the water supplied to the nozzle falls off at various distances from the laminar flow nozzle, depending on the pressure, but, for example, an ow that is actually provided with a drain between the deck slabs. If you have a garden deck with adequate drainage, such as an open joint pavement garden tech, or a large sized pool, you'll have no problem. While interesting results can be achieved from a single laminar flow nozzle, a plurality of side-by-side nozzles guided by a common variable pressure source provides a more interesting display due to the inherent identity in the movement of each of the plurality of classes.

A novel and unique water display is disclosed herein using a laminar flow nozzle and preferably using a laminar flow nozzle that generates slugs for various decorative and recreational purposes. While various embodiments of the present invention have been disclosed herein, it will be understood by those skilled in the art that various modifications may be made without departing from the scope and spirit of the invention.
