The present invention relates to a polka dot generator capable of drawing a horizontal or parabolic line and launching it.

[0002]

2. Description of the Related Art Conventionally, a fountain device has been known as a device for blowing up water for viewing. This fountain device is generally created with various sculptures and three-dimensional structures,
The water blown up by this has been loved by people since ancient times because it gives a cool feeling to the dry atmosphere.

[0003]

However, the shape of the water blown up by the fountain device is rod-like (straight).
Alternatively, it was continuous in a film form (sheet form) or in a splash diffusion form (shower form), or was intermittent and had no unexpectedness.

Therefore, the amusement of the movement of water by appropriately combining the shapes of water in the form of a straight, a sheet, and a shower, and the versatility by combining the movement of water with light and sound have been produced. However, it was naturally limited, and it was extremely difficult to excite more interest.

[0005] In view of the above, the present invention is highly surprising, in which water is formed in a spherical shape (polka dots) and the polka dot is produced as if a catch ball or a polka dot is being passed. It is intended to provide a polka dot generator.

[0006]

In order to achieve the above object, the present invention comprises a water discharging means, and a shutter for shutting off, opening, and shutting off a water flow spouted from the water discharging means.

FIG. 1 is a block diagram showing the overall configuration of the apparatus of the present application, FIG. 2 is a cross-sectional view schematically showing the operation of the shutter, and FIG. 3 is a diagram in which the shutter is run obliquely from the rear to the front in the flow direction of the water flow. FIG. 4 is a cross-sectional view schematically showing the operation of the case in which water droplets are circulated, FIG. 4 is a cross-sectional view schematically showing the operation of the means for restricting splashing around the body of water, and FIG. FIG. 6 is an explanatory view showing a state in which a polka dot is horizontally driven, FIG. 7 is an explanatory view showing a state in which a polka dot is drawn in a parabola, and FIG. It is sectional drawing which shows for reference the effect | action at the time of running across orthogonally.

In FIG. 1, reference numeral 1 denotes a water discharging means. The water discharging means 1 comprises a pump 3 for pumping water in a water tank 2 and a nozzle 6 which communicates with the pump 3 via an electromagnetic valve 4 and a flow control valve 5. Become. Although only two pumps 3 and nozzles 6 are shown in the example of FIG. 1, the numbers of the pumps and the nozzles 6 are not limited.

The water discharged from the nozzle 6 and the water leaking to the outside of the nozzle housing 6a are collected in a receiving tray 6b and discarded into a sewer system or the like. The housing 6a is configured to recover 0, and to return to the water tank 2 to return K.

The water tank 2 is provided with a water level sensor 2a, and when the water level drops by a predetermined amount, the water inflow means 2b
Is activated to supply water. The water tank 2 is provided with an overflow means 2c, and the water flowing out of the overflow means is collected by a storage basin 2d and can be disposed of in a sewer.

The flow control valve 5 is for adjusting the flow rate of water sent from the pump 3 to the nozzle 6, that is, for creating a momentum for causing the water flow 7 discharged from the nozzle 6 to reach a target location. The solenoid valve 4 is for opening and closing the nozzle 6 instantaneously. The ON / OFF timing of the solenoid valve 4 forms an optimum water discharge interval in relation to the control means 9 of the shutter 8.

In front of the nozzle 6 of the water discharging means 1, as shown in FIG.
A shutter 8 for opening and closing is provided. The shutter 8 is operated by control means 9. The control means 9 comprises an air source (such as a compressor) 10, an air regulator 11, an air solenoid valve 12, and an air cylinder 13.

The shutter 8 is fixed to the tip of a piston 13a which reciprocates by an air cylinder 13. An open hole 8a is provided at the center thereof, and blind surfaces 8b and 8c are provided at the front and rear portions of the open hole 8a. ing.

After defining the strength of the water flow 7 ejected from the nozzle 6 of the water discharging means 1, the shutter 8 moves forward by the operation of the control means 9, and as shown in FIG. 2 (a), the front blind face 8b To the front of the nozzle 6 to block the water flow 7.

The shutter 8 is further advanced by the operation of the control means 9, and as shown in FIG.
Coincides with the nozzle 6, the head 7A of the water flow 7, which has been restrained by the front blind surface 8b of the shutter 8, comes out of the open hole 8a and rises as shown by the arrow, but at the next moment, FIG. Thus, the water flow 7 is blocked by the rear blind surface 8c of the shutter 8.

The water flow 7 that has passed through the open hole 8a of the shutter 8 flies in an upward direction as an independent water mass 7 '. This flight is based on the water discharge energy obtained from the water discharge means 1. Thus, the body of water 7 'is deformed into a sphere over time due to the physical phenomenon of water (surface tension phenomenon) during flight.

In the above case, as shown in FIG. 2, the running of the shutter 8 obliquely crosses the water flow 7 ejected from the nozzle 6 of the water discharging means 1 from the rear to the front in the flow direction. The lump 7 'can be cut into a shape that is likely to be spherical due to the surface tension phenomenon.

That is, at the front blind surface 8b of the shutter 8 as shown in FIG. 3A, the head 7A of the water flow 7 is restrained as shown in FIG. Leading edge 8
When a 'reaches the water flow 7, the head 7A of the water flow 7 escapes from that part. As shown in FIG. 3 (c), a part of the head 7A that has escaped in this way has the height of the front edge 8a 'of the opening 8a while the opening 8a of the shutter 8 reaches the position where the water flow 7 is completely opened. It will rise to that point.

That is, the front edge 8a 'of the open hole 8a when the shutter 8 crosses obliquely from the rear to the front in the flow direction of the water flow 7 discharged from the nozzle 6 of the water discharging means 1.
The head 7A of the water flow 7 becomes horizontal with the time difference at which the water flow 7 cuts off the water flow 7.

Subsequently, as shown in FIG. 3C, when the rear edge 8a "of the open hole 8a cuts into the water flow 7 and cuts off the water flow 7 as the shutter 8 travels, as in the case described above. Due to the time difference when the trailing edge 8a ″ of the opening 8a crosses the water flow 7 obliquely, the water flow 7 is cut horizontally as shown in FIG. Therefore, when the water flow 7 is completely interrupted by the rear blind portion 8c of the shutter 8 as shown in FIG. 3 (e), the upper and lower surfaces are horizontal, and a cylindrical water mass which tends to be spherical due to the surface tension phenomenon. It becomes 7 'and rises.

On the other hand, the shutter 8 is replaced with the one shown in FIG.
As shown in (e), when the vehicle is run so as to cross the water flow 7 at right angles, the water flow 7 becomes the front edge 8 of the open hole 8a of the shutter 8.
The head 7A of the water flow 7 becomes an inclined surface by the time difference until the opening hole 8a is completely opened because the part that has escaped from the a 'side precedes.

When the trailing edge 8a ″ of the opening 8a partially cuts into the water flow 7 to cut off the water flow 7, the lower surface of the water flow 7 is similarly inclined by the time difference until the opening hole 8a is completely cut off. Therefore, a water mass 7 'formed by cutting the water flow 7 above and below has a slanted upper and lower surface, and the shape of the water mass 7' is hardly spherical due to the surface tension phenomenon. It can be said.

In front of the water mass 7 'formed by the operation of the shutter 8 in the direction of flight, as shown in FIG. 2, a restriction for restricting the splash 7 "surrounding the water mass 7'. Means 14 is provided. The above-mentioned droplets 7 "are obstacles when the water mass 7 'becomes spherical due to the surface tension phenomenon, and it is preferable that the droplets 7" be surely removed in order to change into a beautiful polka dot. .

The splash control means 14 can be provided with a baffle plate (not shown) having a hole corresponding to the outer diameter of the water mass 7 'on the orbit of the flying water mass 7'. However, in such a case, if the size or flight trajectory of the water body 7 'is slightly deviated, the main part of the water body 7' may be destroyed.

Therefore, the droplet control means 14 includes:
A plurality of elements 1 for forming a hole corresponding to the outer diameter of the water body 7 '
4a and 14b, and the elements 14a and 14b are installed in multiple stages in the flight direction of the water body, and if the installation positions can be finely adjusted, the size of the water body 7 'and the subtle deviation of the flight trajectory can be improved. And the possibility of destroying the main part of the water body 7 'can be further reduced.

In the example shown in the figure, the regulating means 14 is constructed in two stages. However, if it is constructed in three or four stages, it is possible to more reliably remove the droplet 7 "and to form a desirable beautiful polka dot. become able to.

As shown in FIG. 4 (a), after the polka-dotted water mass 7 'flies, as shown in FIG. 4 (a), the water discharge from the nozzle 6 of the water discharge means 1 is stopped. Return to the old position (the front blind portion 8b of the shutter 8 is located in front of the nozzle 6). This completes one polka dot generation cycle.

Next, an example of installation of the present apparatus will be described. FIG. 5 shows a state in which the nozzles 6 of the water discharging means 1 are arranged at regular intervals in the horizontal direction, and a water mass 7 ′ formed by a polka dot is vertically ejected from each nozzle 6. In this case, the launched water mass 7 'falls to the same position at a certain height and disappears, but similarly at the timing when the first water mass 7' falls and disappears, the water mass 7 'is similarly vertically moved. If you do, you can see it as if you were playing a beanbag. In particular, if the nozzles 6 of the water discharging means 1 are installed below the floor surface and the ejection timing from each nozzle 6 is changed, the unexpectedness is further increased.

Also, as shown in FIG.
Are arranged at regular intervals in the horizontal direction, and water droplets 7 ′ formed by polka dots are ejected horizontally from the respective nozzles 6. The ejected water masses 7 ′ hit the shoulders of the adjacent nozzles 6 and disappear.
For example, the water mass 7 'coming out of the leftmost nozzle is
When the water droplets 7 'are ejected horizontally from the adjacent nozzles 6 at the timing of disappearing by hitting the shoulders, and successively ejected like the next adjacent nozzles, it can be appreciated that the shoulders are sequentially knocked in appearance. . In particular, it is more effective if the nozzle 6 is formed in the shape of a predetermined character.

Further, as shown in FIG. 7, the nozzles 6 of the water discharging means 1 are arranged at regular intervals in the horizontal direction, and a water mass 7 'formed by a polka dot from each of the nozzles 6 is drawn in a parabola so as to reach the adjacent nozzle 6. In this way, if the launch timing is sequentially performed from the leftmost nozzle, it is possible to appreciate as if the polka dots were dancing. In particular, when the nozzles 6 of the water discharging means 1 are arranged below the floor in a flat matrix, the floor looks narrow and the polka dots dance. .

In each of the cases shown in FIGS. 5 to 7, it is possible to install several nozzles 6 in different directions, instead of one nozzle 6 at one location. Further, it is needless to say that the direction of the nozzle 6 may be arbitrarily changed by control means such as a computer.
