Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ornamental fountain device that is capable of continuously producing a fountain at a high speed.

[Prior Art] In the case of an ornamental fountain device, when the fountain is ejected from a nozzle rapidly and synchronized with music, etc., conventionally, a solenoid valve or the like that uses electromagnetic force to force water into the fountain nozzle has been used. It was controlled by opening and closing to keep the water gushing out.

[Problem to be solved by the invention] According to the conventional method, when a solenoid valve is opened and closed at high speed, the inertia of the water in the water pipe causes the water to start moving.
Since it takes a long time to stop, there is a drawback that the fountain ejected from the fountain nozzle starts and stops slowly. As a result, the water diameter at the beginning and end of the water jet ejected from the fountain nozzle gradually changes, and the water droplets are scattered and become turbulent. Therefore, it was difficult to synchronize with crisp music.

The purpose of the present invention is to improve these drawbacks, shorten the response time, and obtain a fountain column in which the starting and ending ends of the fountain flow are shaped as if they were cut with a knife.

[Means for Solving the Problems] In order to achieve the above object, the fountain device of the present invention is equipped with an air compressor, an air control valve, an air nozzle, and a water blocker in addition to a water pump and a fountain nozzle. ing. The water shield is fixed at a position close to the fountain's flight path. The air nozzle is also positioned close to and substantially perpendicular to the fountain flight path between the fountain nozzle and the water blocker. The air nozzle and the air compression device are connected via an air amount control solenoid valve.

[Operation] In the fountain configured as described above, if air is not ejected from the air nozzle, the water ejected from the fountain nozzle will fly high in the air without colliding with the water shield and draw a parabolic flight path. . Therefore, the fountain can be seen by the audience.

On the other hand, when the air control solenoid valve opens and a high-speed air stream is ejected from the air nozzle, the water ejected from the fountain nozzle is subjected to air pressure in a direction almost perpendicular to the direction of flight.
Its flight direction changes. As a result, the gushing water collides with the water shield and its direction of motion is directed downward, so it cannot fly high into the air and falls. Therefore, the fountain is no longer visible to the audience and appears to have suddenly stopped.

[Example] Examples will be described with reference to the drawings.

In FIG. 1, water 2 is stored inside a water tank 1, and a submersible pump 3 is fixed inside the tank. The pressurized water from the pump 3 is discharged into the air from the fountain nozzle 5 after excess flow is removed by the rectifier 4.

If there is no action from peripheral devices, the fountain nozzle 5
The fountain flies high in the air above the water tank and falls to the water surface, following a parabolic flight path. To the audience, it appears as if the fountain is coming out of the small tube 9A of the water shield 9, which also serves as a cover for the fountain nozzle, etc., and falling onto the water surface.

An air compressor 6 is installed adjacent to the water tank 1, and compressed air with a pressure of 5 kg/cm ² is supplied from this to the air nozzle 7 via a solenoid valve 8.

When the solenoid valve 8 is closed, no air comes out from the air nozzle 7, so it has no effect on the water jet flow.

When the electromagnetic valve 8 is opened, high-speed air is ejected from the air nozzle 7 and acts on the jet stream. The direction of flight of the water jetted from the fountain nozzle 5 is deflected in the direction opposite to that of the air nozzle 7, since this air is subjected to a force in a direction substantially perpendicular to the direction of movement due to the action of the flow.
As a result, the water from the fountain nozzle 7 flows through the water shield 9
The water passes through the outside of the small cylinder 9A and collides with the cover of the water shield 9. The collided water loses kinetic energy while flowing along the back surface of the water shield 9 and falls to the water surface 2. Since the audience cannot see the water flow behind the water shield, it appears that the water from the small tube 9A has stopped.

[Effects of the invention] Since the present invention is configured as described above, it has the following effects.

The solenoid valve can be opened and closed in a short period of time, and the response of the air flow to this is also quick, so by electrically opening and closing the solenoid valve, the water fountain that comes out of the small cylinder of the water shield can be continued at a high speed. As a result, the fountain and the music can be accurately synchronized. Furthermore, if the opening/closing time of the electromagnetic valve is shortened, parts of the water dropout will occur in the fountain flow flying in the air, resulting in a fountain flow with many breaks. This allows for a new type of fountain that has never existed before.
