Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention uses model flying objects that are mainly installed at event venues such as amusement parks, parks, and expositions to produce a show-like effect. The present invention relates to a fountain device equipped with a fountain device.

BACKGROUND OF THE INVENTION Previously known fountain devices are generally said to be static and lack dynamic elements. Therefore, various measures have been taken to compensate for the lack of dynamic elements, such as making the jet water oscillate or intermittent.

(Problem to be solved by the invention) However, even with conventional fountain devices that have been devised in this way, it is difficult to expect dynamic and varied performance effects because the object of appreciation is the jet water itself, and it is difficult to expect a dynamic and varied performance effect. As a performance at an event venue such as a park or an exposition, it has a weak show effect, lacks topicality, and has problems with its production effect, such as low attention.

The present invention was made in view of the above circumstances, and it is possible to establish an extremely dynamic and magnificent show system, which dramatically increases the topicality and attention of event venues such as amusement parks, parks, and expositions. It is an object of the present invention to provide a fountain device equipped with a model flying object that can be improved.

(Means for Solving the Problems) A first invention made to achieve the above object is a telescopic cylinder in which a model flying object having a fountain nozzle is integrally connected with a plurality of cylinders in a liquid-tight and slidable manner. The telescoping cylinder is fixedly held at the upper part of the uppermost cylinder in the model flying object holding means, which is controlled to expand and contract by supplying and discharging water to the hollow part. The upper hollow part of the model flying object holding means is connected to the fountain nozzle as a water supply passage, and the lowermost cylindrical body of the model flying object holding means is attached to penetrate the bottom of the fountain basin in a liquid-tight manner, and the fountain basin and the telescopic cylinder are connected to each other. The lowermost cylindrical body is communicated with a water supply channel equipped with a valve body and a drainage channel equipped with a valve body, and water is supplied to the fountain nozzle through the hollow part of the telescopic cylinder in the water supply channel. A pump is interposed to serve both the purpose of supplying water to the hollow portion for controlling the extension of the telescopic tube.

Further, in the second invention, the model flying object having the first fountain nozzle is a telescoping cylinder in which a plurality of cylinders are integrally connected in a fluid-tight and slidable manner, and the telescoping cylinder is configured to prevent water from flowing into the hollow portion thereof. The model flying object holding means is fixedly held at the top of the uppermost cylindrical body whose extension is controlled by supplying and discharging the cylinder, and the hollow part of the extensible cylinder serves as a water supply passage to the first fountain nozzle. The lowermost cylindrical body of the model flying object holding means is attached to penetrate the bottom of the fountain basin in a liquid-tight manner, and the fountain basin and the lowermost cylindrical body of the telescoping cylinder are provided with a valve body. A first water supply channel and a drainage channel equipped with a valve body communicate with each other, and a second water channel installed in the fountain pond
A second water supply channel having a valve body branched and extended from the first water supply channel is communicated with the fountain nozzle, and
In the water supply channel, the first tube passes through the hollow part of the telescopic tube.
A pump is interposed to supply water to the fountain nozzle, to supply water to the hollow portion for controlling the extension of the telescoping tube, and to supply water to the second fountain nozzle via the second water supply channel.

(Operation) In the first invention, when the pump is operated with the valve body of the drainage channel closed and the valve body of the water supply channel opened,
The pump supplies water from the fountain pond to the hollow part of the telescoping cylinder through the water supply channel, and the telescoping cylinder expands, causing the model flying object to begin to rise. By functioning as a water supply passage, water is also supplied to the fountain nozzle of the model flying object, and water is ejected from the fountain nozzle. Therefore, the model flying object ascends while spouting water from the fountain nozzle. When the amount of water supplied by the pump is large, the telescoping tube expands at high speed and a large amount of water is spouted from the fountain nozzle. In addition, if the valve body of the drainage channel is opened while the pump is stopped or the valve body of the water supply channel is closed, the water in the hollow part of the telescoping cylinder is drained into the fountain pond, and the telescoping cylinder contracts.
Along with this, the model flying object descends. Furthermore, if drainage and water supply to the hollow part of the telescoping cylinder are carried out simultaneously, the telescoping cylinder will expand or contract at a speed corresponding to the ratio of the amount of water discharged and the amount of water delivered. When the telescopic cylinder contracts at a higher speed than the speed, the model flying object descends while spouting water from the fountain nozzle.

In particular, the structure in which the model flying object holding means is made up of a telescoping cylinder in which a plurality of cylinders are integrally connected in a liquid-tight and slidable manner allows the vertical length and extension of the model flying object holding means in the contracted state to be improved. The effect is that the difference between the vertical length of the model flying object holding means, that is, the stroke, can be made extremely long. installed through the
Due to the configuration in which the model flying object is fixedly held at the top of the top cylinder, the effect of raising and lowering the model flying object between the fountain pond and the area above it is exhibited, so these effects are synergized. By this,
It becomes possible to raise a model flying object from a low level position corresponding to a fountain pond to an extremely high position above it, or to lower it from an extremely high position above a fountain pond to a low level position corresponding to a fountain pond. This effect is exerted.

Therefore, in the first invention, by using a multi-stage telescopic cylinder for the model flying object holding means, the model flying object holding means is made smaller and the fountain pond is made shallower, thereby simplifying the construction work and reducing construction costs. Even if the construction period is significantly reduced, the model flying object can be moved up and down dynamically by increasing the lifting stroke of the flying model.

Furthermore, in the first invention, the same pump can supply water for extending the telescoping cylinder of the model flying object holding means and water supply for spouting water from the fountain nozzle of the model flying object. This makes it possible to minimize the number of pumps required, which helps to further simplify construction work and reduce construction costs.

In the second invention, in addition to the above-described effects described in the first invention, by controlling the valve body of the second water channel, water can be ejected from the second fountain nozzle of the fountain pond. It is.
