[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireworks fountain device and a method for producing a fireworks fountain, and more particularly, to intermittently squirting water from a fountain nozzle to cause a later fountain to flow in the air with respect to a first water mass. The present invention relates to a fireworks fountain device and a method for producing a fireworks fountain that can execute a fountain in a unique form as if a fireworks are being launched by causing the fireworks to be scattered and scattered.

[0002]

2. Description of the Related Art As a fountain device capable of executing a fireworks-like fountain (hereinafter referred to as a fireworks fountain), Japanese Patent Laid-Open Publication No.
A fountain device described in JP-A-7666 is provided. In this fountain device, as shown in FIG. 13, a fountain nozzle 51 is provided in a water storage 50 such as a pool or a fountain pond, and a pipe 5 is provided.
2 connects the fountain nozzle 51 and the T-joint 53, and one side of the T-joint 53 has a pipe 54, an elbow 55, and a vertical pipe 5, which are inclined upward from the T-joint 53.
6 to a three-way solenoid valve (three-way switching valve) 57
The other side of the joint 53 is opened to the water reservoir 50 through a check valve 58 and a strainer 59 that allows only the flow toward the T joint 53, and one port of the three-way switching valve 57.
The air compressor 60 is connected to the port and the other port of the three-way switching valve 57 is open to the atmosphere.

According to this fountain device, before the fountain starts,
The water W is filled by the head of the water storage unit 50 as shown by oblique lines, and the pipe 56 communicates with the atmosphere by the switching operation of the three-way switching valve 57. When the pipe 56 communicates with the air compressor 60 by the operation of the three-way switching valve 57 from this state, high-pressure air is sent into the pipe 56, and FIG.
As shown in (5), the water W in the elbow 55 and the pipe 54 is pressed and spouted from the fountain nozzle 51 to execute the fountain. Then, the three-way switching valve 57 switches the pipe 3
When 6 is communicated with the atmosphere, the head of the water reservoir 50
The check valve 58 is opened as shown in FIG.
Push the water W toward the pipe 52 and the pipe 54,
Finally, the water W is refilled as shown in FIG. 13 to prepare for the next fountain. Therefore, based on the control signal program output to the three-way switching valve 57, it is possible to execute the fireworks fountain giving a feeling that the fireworks are being intermittently launched.

[0004]

However, the above-mentioned conventional fountain device can only execute a simple fountain state in which water intermittently spouted from the fountain nozzle 51 spatters naturally in the air. It is not expected to give the satisfaction of enjoying the novel fountain molding. In addition, the filling speed of the water W related to the repetition cycle time of the fireworks fountain is left to the head of the water storage unit 50, so that the filling time becomes longer. For this reason, the repetition cycle time of the fireworks fountain becomes longer,
Even if there is a request to repeat the fireworks fountain in a short cycle time, there is a disadvantage that the repetition cycle time cannot be reduced.

[0005] Therefore, the present invention provides an unusual appearance as if a fireworks were launched by colliding a later fountain in the air with the first water mass intermittently ejected from the fountain nozzle and causing it to scatter. Fireworks fountain device and fireworks, which can execute the fountain of the present invention, and can easily adjust the repetition cycle time of the fireworks fountain to give the viewer a sense of satisfaction with enjoying the novel fountain formation It aims to provide a fountain production method.

[0006]

According to one aspect of the present invention, there is provided a fireworks fountain device according to the present invention, comprising: a fountain nozzle; pumping means for pumping high-pressure fountain water; And a water pipe for communicating the fountain nozzle,
A water / water switching zone is provided in the middle of the water pipe. The first water / water switching zone communicates with or shuts off both the fountain nozzle and the pumping means, and can be controlled to communicate only with the pumping means. Control means, and second control means for replacing the water / water switching zone from a water-filled state to an air-filled state in the shut-off state for both the fountain nozzle and the pumping means under the control of the first control means. It is characterized by having.

In order to achieve the above object, a method for producing a fireworks fountain according to the second aspect of the present invention is a method for producing a fireworks fountain in which a starting water mass ejected from a fountain nozzle is jetted from a fountain nozzle. The fountain is made to collide with each other to form a fireworks-like fountain in which both are scattered.

According to the fireworks fountain device according to the first aspect of the present invention, the steam / water switching zone is shut off from both the fountain nozzle and the pressure feeding means under the control of the first control means. In the ready state of the fireworks fountain in which air is sealed in the steam switching zone by the control, the steam switching zone is communicated only with the pressure feeding means by the control of the first control means.

When the steam switching zone communicates only with the pumping means, the sealed air in the steam switching zone is compressed by the high-pressure fountain water pumped into the steam switching zone by the pumping means.

Next, the steam / water switching zone is communicated with the fountain nozzle under the control of the first control means.

When the air / water switching zone also communicates with the fountain nozzle, the compressed air is sandwiched between the fountain water on the fountain nozzle side and the high-pressure fountain water on the pumping means side in the water pipe.

At the moment when the compressed air is sandwiched between the downstream fountain water and the upstream high-pressure fountain water, the compressed air and the downstream fountain water are pressure-fed to the upstream high-pressure fountain water. Irrigation water spouts from the fountain nozzle to form a water mass,
Subsequently, the low-pressure air having a low degree of compression is jetted from the fountain nozzle, and then the high-pressure fountain water on the upstream side is jetted.

When the starting water mass spouted from the fountain nozzle starts to spontaneously splinter in the air, the later high-pressure fountain water collides with the sprung water mass that has begun to sprung, and both violently splinter. It is possible to execute a peculiar fountain like a fireworks display.

After execution of the fireworks fountain, the steam control zone is shut off from both the fountain nozzle and the pumping means under the control of the first control means, thereby stopping the fireworks fountain and maintaining the steam-water switch zone in a full state. I do. Subsequently, the steam-water switching zone is changed from the water-filled state to the air-filled state under the control of the second control means, thereby returning to the fireworks fountain ready state. Thereafter, by repeating the above operation, the fireworks fountain can be executed intermittently.

Further, by adjusting the total amount of time per cycle necessary for the control operation of the first control means and the second control means, the repetition cycle time of the fireworks fountain can be easily adjusted.

According to the method for producing a fireworks fountain according to the second aspect of the present invention, it is possible to execute a fountain having a peculiar form as if a fireworks were launched.
