Description

[Detailed Description of the Invention] This invention relates to a fountain device for a garden pond or the like, and particularly to a device that can change the appearance of water that is sprayed. The gist of the invention of the present application is to provide an on-off valve for switching the fountain nozzle, which is switched by the water flow of the pump, between the jet pipe of the pump and the fountain nozzle, and to utilize pumped water energy. The amount of water injected from the injection hole is changed by automatically changing the opening degree of the valve.

Below, we will explain this idea in detail based on the drawings.
First, the configuration is as shown in the figure, a submersible pump 1
A rotatable jet pipe 3 is provided opposite to the spout port 2, a rotary plate 4 for valve actuation that can rotate in conjunction with the jet pipe 3, and an inclined portion 5 on the surface of the rotary plate 4. and a fountain nozzle 6 at the top.
An on-off valve 9 is provided at the inlet 8 of the plurality of distribution chambers 7...
One end of the valve stem 10 of this on-off valve 9 is brought into contact with the surface of the rotating plate 4, and the valve stem 10 is slid in the longitudinal direction by rotation of the rotating plate 4. . The plurality of distribution chambers 7 are arranged concentrically, and an on-off valve 9 is attached to the inlet 8 of each distribution chamber 7.

Next, to explain in detail the opening/closing device of the opening/closing valve 9, as shown in FIGS. 2 and 3, a spring 11 is inserted into the valve stem 10 of the opening/closing valve 9,
is applied to the inlet 8 of the distribution chamber 7, and the valve stem 1
One end of the valve arm 12 is pivotally connected to the central part 13 of the valve arm 12, and one end of the valve arm 12 is connected to the lower part 14 of the bottom wall of the distribution chamber 7.
A roller 15 is provided at the other end, and this roller 15
is brought into contact with the rotating plate 4, and the rotation of the rotating plate 4 causes the valve stem 10 to slide in the longitudinal direction. Further, reference numeral 16 is a valve box, and a large number of openings 17 are provided around the periphery. And rotating plate 4
As shown in FIG. 2, the drive device includes a jet pipe 3 mounted on a rotating shaft 18, a central portion 19 of the jet pipe 3 facing the jet port 2 of the pump 1, and left and right arms 20,
20 are provided with openings 21, 21 in opposite directions, a driving gear 22 is fitted onto the rotating shaft 18, and a driven gear 23 is meshed with the driving gear 22.
and the rotary plate 4 are fitted onto the driven shaft 24, and both ends of the rotary shaft 18 and the driven shaft 24 are held by support plates 26, 26 fixed to the side wall of the working chamber 25. Note that the reference numeral 27 is a frame body having a float 28 on its upper circumference, into which a cylindrical strainer 29 and a fountain device 30 are inserted.
Water is drawn into the submersible pump 1 through a strainer 29. And the float 28
The fountain nozzle 6 provided in the upper part of the distribution chamber 7 is positioned above the water surface, and the fountain device 30 is movable. Code 31 is the water surface, 32
3 is a cable, 33 is a rope for suspension, 34 is a locking belt, and 35 is a weight for fixing the position.

Next, the operation of this invention will be explained. Since this invention is constructed as described above, when the fountain device 30 is installed at a desired position and the submersible pump 1 is started, the water flowing out from the pump 1 passes through the central part 19 of the spout pipe 3. Openings 21 of left and right arms 20, 20,
It erupts from 21. At this time, the jet pipe 3 rotates due to the water jet energy, and this rotational force is transmitted to the drive gear 2.
2 to the driven gear 23, and also rotates the rotary plate 4 provided coaxially with the driven gear 23. As the rotating plate 4 rotates, the roller 1 provided on the valve arm 12 rotates.
5 swings up and down while rolling, so the valve stem 1
0, the valve body 36 also slides up and down at the same time, changing the aperture ratio of the inlet 8 of the distribution chamber 7. and,
The flow rate flowing into the distribution chamber 7 also changes moment by moment, so that the amount of water jetted from the fountain nozzle 6 above the water surface 31 can be changed.

As described above, the invention of the present application converts pumped water energy into rotational motion, transmits this rotational motion to back and forth motion to slide the valve body, and automatically switches the opening ratio of the valve. , there is no need for a special water injection amount switching device, and maintenance costs are low. Furthermore, by replacing the rotary plate with rotary plates of various shapes as shown in FIGS. 1, 2, and 3, it is possible to realize various water appearances with one fountain device. In the embodiment, a fountain device using a submersible pump has been described, but the pump may be installed on the ground, and tap water may be used in a small garden pond.
