Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a movable fountain device for demonstration purposes.

<Prior art> A structure in which a fountain device is mounted on a floating body (hereinafter referred to as a "barge") that moves on water has already been developed, but the following problems were encountered.

<B> Conventional fountain devices are structures that are fixed to the bottom of ponds or lakes, and are equipped with a motorized pump and nozzle.

However, in reality, it is not easy to create a structure that is fixed to the bottom of the water, and manufacturing costs are high.

<B> Furthermore, conventional devices rely on electric power transmitted from land as a power source.

This requires underwater wiring, but since it is difficult to monitor underwater, there is a possibility of an accident occurring.

<Objective of the present invention> The present invention has been made in order to improve the above-mentioned drawbacks, and an object of the present invention is to provide the following fountain device.

<A> A fountain device that is easy to install on water.

<B> A fountain device that does not require power from land.

<Structure of the present invention> Next, one embodiment of the structure of the present invention will be described.

<A> Overall structure The fountain device of the present invention is constructed by mounting an engine 2, a pump 3, and a nozzle 4 on a barge 1.

<B> Barge: As long as the barge 1 is a container that floats on water, a known structure can be used.

For example, it is made of steel, concrete, FRP, etc.

Inside this barge 1, an engine 2, a pump 3,
Retract and fix the nozzle 4.

In order to minimize the sway of the barge 1 due to waves, a sway reduction device is installed to suppress it.

The shape of barge 1 is as wide as possible horizontally,
If a shallow structure, that is, a flat structure is used, and the various equipment described below are evenly arranged inside the structure, stability will be improved.

<C> Engine As the engine 2, an independent type engine such as a known diesel engine is used.

An independent structure such as a diesel engine eliminates the need to introduce energy from an external power source.

For this purpose, there is an oil tank 21 inside the barge 1.
Set it up.

<D> Pump Furthermore, a fountain pump 3 is installed inside the barge 1.

The structure is simple if the rotating shaft of the pump 3 and the rotating shaft of the engine 2 are connected through a reduction gear or the like.

In addition, when adopting the pump 3 of the type with an electric motor, a generator is installed.

By installing a plurality of pumps 3 and appropriately distributing their arrangement, it is possible to minimize the shaking of the barge 1 due to mechanical vibrations.

<E> Nozzle Piping is done so that the water compressed by the pump 3 is supplied to the nozzle 4.

This nozzle 4 is installed near the center of the barge 1, facing vertically upward.

Rather than being completely fixed, the nozzle 4 can also be mounted so that its direction can be adjusted.

<f> Other devices A separate auxiliary generator is installed for the lighting device that illuminates the fountain from the nozzle 4 and the lighting inside the barge 1.

A receiver is installed so that the engine 2 and generator can be controlled wirelessly from land.

<How to use><A> Installation The barge 1 of the present invention is transported to the vicinity of the exhibition site such as a lake, sea, pond, etc. and floated on the water.

In this case, barge 1 can be propelled by itself if an outboard motor is attached to it, but it can also be pulled by another ship, or if it is a narrow area of water, it can be moved from land using a winch via a wire. .

<B> Injection Start engine 2 by radio from the ground,
Adjusts the rotational speed of the pump, opens and closes the valves on the piping to the nozzle 4, starts the fountain lighting engine, and opens and closes the switches.

Therefore, water can be sprayed to a set height when required.

<Effects of the Invention> Since the device of the present invention has the above-described structure, the following effects can be expected.

<B> It is not a type that is fixed to the bottom of the water, but a floating type.

Therefore, regardless of the water depth at the location where it is installed,
Demonstrations can be held at any location.

<B> For the above reasons, the installation cost remains almost constant regardless of the water depth, and the venue can be set up stably.

<C> Everything from the power source to the nozzle is installed inside the barge 1.

Therefore, there is no need for connection to the outside, and the navigation of surrounding ships will not be affected.

<D> Since it is installed on the water, it is impossible to avoid vibrations caused by the rotation of the power source, pump, etc., and disturbances caused by waves.

However, if a flat barge is used and each piece of equipment is placed evenly on a plane, the center of gravity will be lower and the structure will be less likely to sway.

<E> The equipment required for all injection operations is installed inside the barge.

Therefore, it is easy to change position or evacuate depending on the wind direction or wave conditions.

Similarly, since it is easy to move, demonstrations can be held at different locations in large venues.

<F> As mentioned above, the device of the present invention is configured so that it can be installed independently from land, so depending on the venue situation, it can be connected to a power source on land or connected to a pipeline. Of course, it is also possible to supply oil by
