Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a float type fountain device in which a float has a fountain nozzle.

[0002]

2. Description of the Related Art Conventionally, this type of float type fountain device is
The float only had its own buoyancy. For this reason, the fountain device remains floating above the water both during operation of the fountain and at rest, and it is impossible to submerge it or change the submersion depth as necessary.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances. In a float type fountain device, it is possible to float above the water, and of course, to submerge it or to adjust the submerged depth. An object is to provide a float type fountain device that can be changed.

[0004]

According to a first aspect of the present invention, there is provided a float type fountain device in which a float having a variable buoyancy is equipped with a fountain nozzle.

In the float type fountain device constructed as described above, the float of variable buoyancy is used for controlling the hollow tank and the supply / drainage / exhaust of the hollow tank. And a means for controlling water supply / drainage and air supply / exhaust to / from the hollow tank are provided in the upper portion of the hollow tank, as in the invention according to claim 3. It is possible to employ a configuration in which a control on-off valve, a water supply / drainage water passage provided at the bottom of the hollow tank, and an air supply system for supplying air to the hollow tank are provided.

[0006]

In the invention according to claim 1, in the fountain device, when the buoyancy of the float is reduced, it is submerged in water, and when the buoyancy is increased, it is floated on the water, and the submersion depth is changed by adjusting the buoyancy.

According to the second aspect of the invention, the buoyancy of the float is adjusted to be increased or decreased by controlling the amount of water supplied to and discharged from the hollow tank and the amount of air supplied and discharged. At that time, if the amount of water supply and drainage and the amount of air supply and exhaust are adjusted steplessly, the buoyancy of the float is also adjusted steplessly, and the floating of the fountain device above water, submersion in water, adjustment of submersion depth, etc. can be freely performed.

In the invention according to claim 3, when the on-off valve is opened, water is supplied to the hollow tank from the water passage due to the weight of the fountain device, and when the on-off valve is closed during such water supply, water supply is stopped. When the open / close valve is closed and air is supplied to the hollow tank containing water from the air supply system, the water in the hollow tank is pushed out from the water passage, and when the air supply is stopped, water will flow out from the water passage. Stop. The buoyancy of the float is determined by the amount of air in the hollow tank. When the amount of air increases, the buoyancy increases, and when the amount of air decreases, the buoyancy decreases.

1 and 2 are side views schematically showing the operation of a float type fountain device according to an embodiment of the present invention according to claims 1 to 3, and FIG. 3 is a schematic plan view of the float type fountain device. It is a figure.

This float type fountain device is equipped with a float 1
And a fountain nozzle 2 mounted on the float 1, and two submersible pumps 3 and 3 for pumping water to the fountain nozzle 2.
And a plurality of hollow tanks 1 provided in the float 1 as well as a sitting leg 4 attached to the float 1 and a weight 6 connected to the float 1 by a cord 5 such as a chain.
1 is provided with a means (hereinafter, referred to as a steam supply / discharge control means) 7 for controlling the supply / discharge amount and the supply / exhaust amount.

As shown in the figure, the float 1 is provided with hollow tanks 11 ...
The structure is connected with. And the submersible pumps 3 and 3 are installed in front of and behind the stand 12, respectively,
The fountain nozzle 2 is installed at the center of a frame 12 surrounded by the hollow tanks 11, ..., And the submersible pumps 3, 3.
It is desirable that the submersible pumps 3, 3 send water to the fountain nozzle 3 by operating them, such as water in the hydrosphere where the fountain device is installed, for example, a pond, an artificial pool, a lake, or the sea. Water may be sent to the fountain nozzle 3 from a place.

As shown in FIGS. 1 and 2, the air / water supply / discharge control means 7 is provided with an electromagnetic on-off valve 71 for exhaust control provided on the upper part of each hollow tank 11 ... And each hollow tank 11 ... Water supply port 72 for water supply and drainage provided at the bottom ...
And an air supply system 73 for supplying air to the respective hollow tanks 11 ..., The air supply system 73 is provided with a flexible air supply pipe (air supply) installed in each hollow tank 11. Tube 74 and its air supply, such as its compressor.

The float type fountain device configured as described above is carried into the hydrosphere, and its installation position is determined by the weight 6. When the electromagnetic opening / closing valve 71 is opened, the hollow tank 11 is discharged from the water passage 72 due to the weight of the fountain device.
When the electromagnetic opening / closing valve 71 is closed during such water supply, the water supply to the hollow tank 11 is stopped. During water supply, the air accumulated in the hollow tank 11 corresponding to the amount of water supply escapes to the outside through the electromagnetic opening / closing valve 71, the buoyancy of the float 1 gradually decreases, and the fountain device submerges as indicated by arrow S. Go. Therefore, as shown in FIG. 1, the seating leg 4 can reach the bottom of the water G and be submerged to a position where the fountain device bottoms, or the submersion depth of the fountain device can be adjusted.

When the electromagnetic on-off valve 71 is closed and air is supplied to the hollow tank 11 containing water from the air supply system 73, the water in the hollow tank 11 is pushed out from the water passage 72 to the outside,
When the supply of air is stopped, the outflow of water from the water passage 72 is stopped. Since the amount of air in the hollow tank 11 gradually increases during air supply, the buoyancy of the float 1 gradually increases correspondingly, and the fountain device floats up like arrow F. Therefore, the fountain device can be floated on the water as shown in FIG. 2 or the submersion depth can be adjusted.

In the present embodiment, the air supply system 73 includes an air supply source such as an air supply pipe 74 and a compressor. Generally, the air supply pipe 74 is connected to the hollow tank 11 from a land-based air supply source.
In some cases, a pressure vessel filled with air can be used as the air supply system 73. In addition,
The electromagnetic opening / closing valve 71, opening / closing control, operation control of the submersible pump 3, etc. are generally based on a command from the land.

[0016]

According to the invention of claim 1, the buoyancy of the float is adjusted to levitate the fountain device on the water,
Since it can be submerged or the submersion depth can be freely adjusted, for example, it is possible to float the float above the water only when the fountain is in operation and hide the float and the entire fountain device under water during operation suspension. It is possible, and the float can be submerged in applications where it is not desirable to have obstacles on the water. Furthermore, it is possible to utilize the movements of the floating and submerged processes of the fountain device for the production of the fountain. Therefore, according to the present invention,
It becomes possible to provide a float type fountain device which can be adapted to various places and uses.

According to the inventions of claims 2 and 3,
Since the weight of the fountain device is used for adjusting the buoyancy of the float, there is an advantage that the structure of the means for controlling the amount of water supplied and discharged and the amount of gas supplied and discharged to and from the hollow tank is simplified.
