Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fountain device installed and used in a reservoir of a park, for example.

[0002]

[Prior art]

 In the conventional fountain device, as shown in FIG. 5, a fountain nozzle 101 installed in a reservoir or the like and a discharge side of a pump 103 driven by a motor 102 are connected via a water supply pipe 104. At the same time, an electromagnetic valve 105 is interposed in the water supply pipe 104, and the electromagnetic force is supplied to the nozzle 101 by driving the pump 103 to supply a certain amount of water through the water supply pipe 104. By controlling the opening / closing of the valve 105, the water W is ejected from the nozzle 101 or stopped to change the height of the water column.

[0003]

[Problems to be solved by the device]

 Since the conventional fountain device having the above-described configuration is configured to eject and stop the water W from the nozzle 101 by controlling the opening / closing of the solenoid valve 105 provided in the water supply pipe 104, Not only the responsiveness is poor due to the distance from the nozzle 101, but also the solenoid valve 105 itself is expensive, resulting in an increase in overall cost.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fountain device that can control the height change of the fountain with good responsiveness and that can be manufactured inexpensively as a whole. I am trying.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the fountain device according to the present invention sets a nozzle for a fountain in a substantially upward posture so that it can be raised and lowered with respect to the water surface, and the nozzle is set to a raised position where its tip projects above the water surface. It is equipped with an electromagnetic solenoid mechanism that displaces it to a lowered position that is submerged below the surface of the water.

[0006]

[Action]

 According to the present invention, when the electromagnetic solenoid mechanism is turned on, for example, from the off state, the tip of the nozzle is immediately displaced to the raised position protruding above the water surface, and the height of the fountain from the nozzle is increased. can do. Further, when the electromagnetic solenoid mechanism is turned off, the nozzle is rapidly displaced to the lowered position where the tip of the nozzle is submerged below the water surface, and the height of the fountain from the nozzle can be reduced. At this time, if the lower position of the nozzle is set so that its tip is below the surface of the water, the water ejected from the nozzle will be low enough to raise the surface of the water, which will cause a change in the height of the water column. You can Moreover, since the nozzle is displaced by the electromagnetic solenoid mechanism, the height of the fountain can be changed as described above with good responsiveness, and since an expensive electromagnetic valve is not used, the manufacturing cost can be kept low.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are vertical sectional views showing a fountain device according to an embodiment of the present invention in different operating states.

In FIGS. 1 and 2, reference numeral 1 denotes a nozzle for a fountain installed in a reservoir such as a park in an upward posture, and is set so as to be able to move up and down with respect to the water surface S. Reference numeral 2 denotes a pump driven by a motor 3 for supplying water to the nozzle 1, and a discharge side thereof and a base end 1a of the nozzle 1 are connected via a water supply pipe 4 such as a flexible hose. There is.

Reference numeral 5 denotes an electromagnetic solenoid mechanism that is located concentrically with the nozzle 1 and is installed in water. The electromagnetic coil 7 is wound around an annular spool 6, and is externally fitted and fixed to the nozzle 1. And a cylindrical iron core 8 driven by the electromagnetic coil 7, and controlling the energization of the electromagnetic coil 7 causes the nozzle 1 to move to a raised position (Fig. 2) where its tip 1b projects above the water surface. , Its tip 1b is selectively displaced to a descent position (FIG. 1) in which it is submerged below the water surface.

In the above structure, when the pump 2 is driven by the motor 3, the pump 2 sends water to the nozzle 1. At this time, when the electromagnetic coil 7 in the electromagnetic solenoid mechanism 5 is energized, an upward electromagnetic attraction acts on the iron core 8, so that the nozzle 1 ascends together with the iron core 8, and the tip 1b thereof is as shown in FIG. Then, it is displaced to a raised position that slightly protrudes above the water surface. Therefore, the water W is ejected from the nozzle 1 as a comparatively high water column.

Further, if the electromagnetic coil 7 is de-energized from this state, the electromagnetic attraction force is lost, so that the nozzle 1 suddenly drops together with the iron core 8 due to its own weight and the fountain reaction force, and the tip 1b thereof. Is displaced to a descending position which is submerged below the water surface, as shown in FIG. Therefore, the water W from the nozzle 1 is suppressed to a height such that the water surface is slightly raised. In this way, by controlling the energization of the electromagnetic coil 7, it is possible to obtain a fountain state in which the height of the water column is drastically changed. In particular, since the nozzle 1 is directly moved up and down by the electromagnetic solenoid mechanism 5, the response time when the water W is jetted high is extremely shortened, and a relatively expensive solenoid valve is used. Since it is not used, the manufacturing cost of the device can be kept low.

3 and 4 show another embodiment of the present invention, in which the electromagnetic solenoid mechanism 5 itself is driven between the lowered position shown in FIG. 3 and the raised position shown in FIG. The second electromagnetic solenoid mechanism 31 is installed. Specifically, a second electromagnetic coil 33 wound around an annular second spool 32 concentrically located in the electromagnetic solenoid mechanism 5 and fixed to the outer peripheral side of the spool 6 in the electromagnetic solenoid 5 are fixed. The second electromagnetic solenoid mechanism 31 is constituted by the annular second iron core 34 driven by the second electromagnetic coil 33.

In this case, as shown in FIG. 3, in a state where the second electromagnetic coil 33 is cut off, when the electromagnetic coil 7 is energized and cut off, the nozzle 1 is moved to a position where the tip 1b of the nozzle 1 rises below the water surface. It is possible to selectively set two positions, that is, the (chain line position) and the lowered position (solid line position). In addition, when the second electromagnetic coil 33 is energized, the nozzle 1 is positioned so that its tip 1b is above the water surface. Two positions can be selected and set: a raised position (chain line position) and a lowered position (solid line position). That is, it is possible to obtain a versatile fountain state in which the height of the water column is further changed as compared with the above embodiment.

[0014]

[Effect of device]

 As described above, according to the present invention, the fountain nozzle, which is set so as to be able to move up and down with respect to the water surface in a substantially upward posture, is sunk to the rising position where the tip projects above the water surface and the water surface by the electromagnetic solenoid mechanism. Since it is displaced to the lowered position, it is possible to obtain a fountain state in which the height of the water column is drastically changed, and to have excellent responsiveness at the time of fountain, and also to reduce the cost of the entire device.
