BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fountain device used for, for example, ponds, lakes and marshes, and more particularly to a fountain device capable of intermittently spraying mixed water containing a large amount of oxygen into the outside air. It is.

[0002]

2. Description of the Related Art As a conventional fountain device, there is a device in which water in a pond or the like is pumped up by a pump and sprayed into the outside air from a nozzle connected to the discharge side of the pump. In the case of this device, the pump is driven and stopped at a constant cycle by the control device, so that water is intermittently sprayed. The sprinkled water has the effect of entraining air and falling into the water when it falls into a pond or the like.

[0003]

However, according to the above-mentioned conventional fountain device, most of the air only enters the water near the water surface of a pond or the like. I couldn't do much. For this reason, it is not possible to decompose or remove, for example, organic substances, which are decomposed by oxygen, to a certain degree or more, and it was not possible to sufficiently purify water. Accordingly, an object of the present invention is to provide a fountain device that can promote purification of water in a pond or the like by spraying water in which a large amount of oxygen is dissolved into the pond or the like.

[0004]

The main means adopted by the present invention in order to achieve the above object is that the gist of the invention is that in a fountain device for fountain into the outside air, water stored in a pressure vessel is subjected to high pressure. A mixed water generating means for supplying air to generate mixed water mixed with air, a water spraying means for spraying the generated mixed water into the outside air, the mixed water generating means and the water spraying means And valve means for opening the valve when the water pressure in the water path becomes equal to or higher than a predetermined value and supplying the mixed water to the water sprinkling means. It is constituted as a fountain device characterized by the above.

[0005]

In the fountain device according to the present invention, the mixed water generation means first stores water in the pressure vessel and supplies high-pressure air to the stored water. As a result, mixed water mixed with air is generated. Therefore, the water spraying unit sprays the generated mixed water into the outside air. At this time, the valve means closes when the water pressure in the water channel connecting the mixed water generation means and the water sprinkling means is equal to or less than a predetermined value to supply water of the mixed water to the water sprinkling means. On the other hand, when the water pressure is equal to or higher than the predetermined value, the valve is opened to supply the mixed water to the sprinkling means. As a result, the mixed water containing a large amount of oxygen in the air is intermittently sprayed into the outside air. As a result, it is possible to promote the purification of water in a pond or the like where the sprinkled mixed water lands.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; It should be noted that the following embodiment is an example that embodies the present invention and does not limit the technical scope of the present invention. Here, FIG. 1 is a configuration diagram showing a schematic configuration of the fountain device according to one embodiment of the present invention. As shown in FIG. 1, a fountain device 1 according to the present embodiment includes a pressure vessel 7 for storing water W in the vessel,
A compressor 6 for supplying high-pressure air A into the pressure vessel 7, a pump 5 for pumping water from a pond or the like and supplying the pressure to the pressure vessel 7, and a stirring blade 2 for stirring water W in the pressure vessel 7
connecting a stirrer 2 provided with a _a, a nozzle 4 sprinkling admission water W _a which air is mixed in the pressure vessel 7 to the outside air in (an example of water spray means), and the pressure vessel 7 and the nozzle 4 A water pressure in the pipe 8 provided in the pipe 8 (an example of a water channel) is set to a predetermined value (for example, 15 kg / cm ^2.
closed when less than atg) to open when equal to or greater than the predetermined value the solenoid valve to the water supply to the admission water W _a to the nozzle 4 3
(An example of valve means). In this case, the solenoid valve 3 is driven and controlled by a control device (not shown) so as to close when the pressure in the pressure vessel 7 is less than the predetermined value and to open when the pressure in the pressure vessel 7 exceeds the predetermined value. . Therefore, in the fountain device 1 having the above configuration, the electromagnetic valve 3
With the valve closed, water W is introduced into the pressure vessel 7 by the pump 5.
Is stored, and high pressure air is supplied into the pressure vessel 7 by the compressor 6, and the stirring blade _2a of the stirrer 2 is driven to rotate at high speed. Thus, the water W in the pressure vessel 7 by being vigorously stirred, the air admission water W _a which is mixed to produce. Oxygen in the air in keeping a large amount for this admission water W _a. That is, the configuration mainly including the pressure vessel 7, the compressor 6, the pump 5, and the stirrer 2 is an example of the mixed water generation means according to the present invention.

[0007] Thus, when the pressure in the pressure vessel 7 is equal to or more than the predetermined value, the electromagnetic valve 3 is opened the admission water W _a is the water supply to the nozzle 4, into the outside air in from the nozzle 4 Sprinkled. At this time, by sprinkling water drops into the pond or the like, as well the air caught in the water is mixed in water, a large amount of air to admission water W _a himself that the fall is mixed Therefore, the amount of dissolved oxygen in the water in the entire pond can be made relatively large. As a result, it becomes possible to decompose and remove a large amount of, for example, organic substances, which are decomposed by oxygen in the water, and it is possible to sufficiently purify the water. Then, in the bubbler 1, the pressure drop in the pressure vessel 7 by sprinkling the admission water W _a is generated, the electromagnetically valve 3 is closed, the electromagnetic valve 3 closing operation in the pressure vessel 7 The pressure is maintained until the pressure becomes equal to or higher than the predetermined value. Such repetition of closing-opening operation of the solenoid valve 3, since the admission water W _a is intermittently watering from the nozzle 4,
The fountain device 1 exhibits the taste of an artificial geyser, and strongly attracts interest in what is seen. At the same time, it is an intermittent fountain, so the amount of water in the fountain can be reduced. Furthermore,
The Admission water W _a which is sprinkled from the nozzles 4, since a large amount of air is mixed is irradiated with, for example, night lighting the admission water W _a, the appearance emerged white strong water film Will increase. Further, since the mixed water W _a contains air, which is a high-pressure compressible fluid, the apparent viscosity coefficient becomes smaller as compared with the case where only water is ejected at the same pressure, and the mixed water W is ejected from the nozzle 4. It will be easier. In addition, the effect of expanding the water in the water immediately after it is released into the atmosphere has the effect of blowing up water much higher. It should be noted that the drive of the pump 5 and the compressor 6 is stopped in conjunction with the valve closing operation of the solenoid valve 3, while the drive of the pump 5 and the compressor 6 is started in conjunction with the opening operation of the solenoid valve 3. It is also possible to configure. The high-pressure air from the compressor 6 may be directly injected into the water W stored in the pressure vessel 7 as shown by a two-dot chain line in the figure. Thereby, the action of mixing air into the water W can be made more effective. In this case, it is more effective to adopt a configuration in which air having a fine bubble diameter is generated in the water W in an injection nozzle (not shown) of the air injected into the water W.

[0008]

According to the present invention, in a fountain device that fountains into the outside air, a high-pressure air is supplied to water stored in a pressure vessel to generate a mixed water mixed with air. A water sprinkling means for sprinkling the generated mixed water into the outside air; and a water passage provided in the water passage connecting the water mixture means and the water sprinkling means, wherein a water pressure in the water passage is set to a predetermined value. A fountain device is provided, comprising: valve means for opening the valve at the time of the above to supply the mixed water to the water sprinkling means. Thus, water in which a large amount of oxygen has been dissolved can be sprinkled into, for example, a pond. Therefore, it is possible to decompose and remove, for example, organic substances and the like contained in the water of the pond and the like, and it is possible to promote the purification of the water. In addition, due to the expansion action of the high-pressure air immediately after watering, water can be sprayed at a higher pressure than when only water is sprayed at the same pressure.
