Abstract

PURPOSE:To save installation cost and running cost by performing water spouting by using kinetic energy of waves generated by a natural phenomenon. CONSTITUTION:Pressurizing and pressure lowering are repeated in an air room 10 of a pressurized air feeding tank 1 by means of movement of the wave (WE) to feed the pressurized air into an accumulator 21 of an pressure accumulation tank 2 and when the air pressure in the accumulator 21 is elevated to a set value, a water spouting valve 4 is opened to spout water from a water spouting nozzle 31. In addition, the pressure of the accumulator 21 is detected by means of a pressure sensor 14 and the detected pressure signal is inputted into a controller 9 to output a valve opening signal to the water spouting valve.

A water fountain system in which the inlet side is submerged in the water stored in the water storage unit and the fountain port is exposed to the outside of the pressure storage tank, and the air chamber and the pressure storage chamber communicate with each other, and the air of the pressure storage unit It is characterized in that a fountain valve that opens and fountains when the pressure is raised to a set value is provided in the fountain system.By performing the fountain by the kinetic energy of waves generated by a natural phenomenon, the equipment cost and running cost are reduced. Achieved the goal of reduction.

[0005]

According to the present invention, due to the motion of the waves, the pressure increase and the pressure decrease are repeated in the air chamber of the pressure increased air supply tank. The air whose pressure has been increased in the air chamber is sent to the pressure accumulating unit of the pressure accumulating tank to increase the pressure of the pressure accumulating unit. The air pressure boosted by the pressure accumulator is applied to the water storage surface of the water storage. The fountain valve opens when the air pressure in the accumulator rises to the set value. The water in the reservoir is
The air pressure boosted to the set value that is loaded on the reservoir surface causes it to be pumped to the fountain system and ejected from the fountain port.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of the present invention. In this figure, 1 is a boost air supply tank, 2 is a pressure storage tank, 3 is a fountain system, and 4 is a fountain valve. The boosted air supply tank 1 is for converting the motion of waves into a boosted pressure change in the air chamber 10 and sending out air, and is formed of a non-rusting metal in a downward cup shape and has a lower end opening 11 thereof. And its vicinity are submerged in water, and are attached to, for example, a column 6 installed on the seabed 5. An intake valve 12, which is a check valve, is attached to the boosting air supply tank 1, and the air chamber 10 communicates with the atmosphere via the intake valve 12. The accumulator tank 2 has a watertight section 20 for storing the fountain water W and a pressure accumulator section 21 composed of a space formed above the water reservoir section 20, and has a closed structure.
Installed on. Of course, the pressure accumulating tank 2 may be installed on the land side. The fountain water is appropriately supplied to the water storage section 20 from a water supply port 23 which is always closed by a lid 22. The pressure accumulator 21 of the accumulator tank 2 and the air chamber 10 of the boosted air supply tank 1 are provided with an exhaust valve 13 which is a check valve.
Are communicated with each other by an air supply pipe 8 provided therebetween. The fountain system 3 is composed of a vertical water fountain introduction pipe 30 and a fountain nozzle 31 connected to the upper portion of the fountain water introduction pipe 30. The fountain system 3 submerges the inlet 30a of the fountain water introduction pipe 30 into the fountain water (reservoir) W of the water reservoir 20, and sets the fountain nozzle 31 to the accumulator tank 2.
It is installed in the accumulator tank 2 in a state in which it is located on the upper part of 2. The fountain valve 4 is an electromagnetic valve and is provided in the fountain water introduction pipe 30 of the fountain system 3. On the other hand, the pressure of the pressure accumulator 21 is detected by the pressure sensor 14, and the detected pressure signal is input to the controller 9. The controller 9 compares the input pressure signal value with the previously input set value, and when the pressure signal value input from the pressure sensor 14 has risen to the set value, an opening signal is sent to the fountain valve 4. Is output. The pressure sensor 14 and the controller 9 may be omitted by using a well-known pressure valve that opens at the set pilot pressure as the fountain valve 4. Further, in place of the water supply port 23 which is always closed by the lid 22, 5
By providing the water check valve 0 for water supply in the accumulator tank 2, it is possible to automatically supply water when the pressure in the accumulator tank 2 drops due to the fountain.

With such a structure, the movement of the wave WE lowers the water level WL in the boosted air supply tank 1 from the level of h1 to the level of h0, so that the pressure in the air chamber 10 is lowered and the intake valve 12 is opened. Let it inhale. on the other hand,
As the water surface WL in the boosted air supply tank 1 rises from the level of h0 to the level of h1, the air chamber 10
Boosts. In other words, due to the motion of the waves, the pressure increase / reduction is repeated in the air chamber 10 of the pressure increased air supply tank 1. The pressure-increased air opens the exhaust valve 13, is sent to the pressure accumulator 21 of the accumulator tank 2 through the air supply pipe 8, and gradually increases the pressure of the pressure accumulator 21. The pressure of the pressure accumulator 21 is detected by the pressure sensor 14, and the detected pressure signal is input to the controller 9. At the time when the pressure signal value input from the pressure sensor 14 is increased to a set value that is input in advance to the controller 9, the fountain valve 4 is output by the valve opening signal output from the controller 9.
Open the valve. The water in the water storage section 20 is jetted from the fountain nozzle 31 through the fountain system 3 by the air pressure boosted to the set value loaded on the water storage surface WL to perform fountain. The fountain valve 4 is closed due to the pressure drop in the pressure accumulator 21. Hereinafter, intermittent fountain is performed by repeating the above-mentioned operation.

As described above, since the fountain is generated by utilizing the kinetic energy of the wave generated by the natural phenomenon, it is possible to omit the use of devices such as a pump and a pump driving prime mover. Therefore, it is possible to reduce equipment costs and running costs.

In the above embodiment, the boosted air is sent from one boosted air supply tank 1 to the accumulator tank 2, but a plurality of boosted air supply tanks 1 to one accumulator tank 2 are described. You may make it pressurize air into. Further, the present invention can also be used for irrigation as a water supply device corresponding to a pump that utilizes the tide wave force.

[0010]

As described above, according to the present invention, the fountain can be generated by utilizing the kinetic energy of the wave generated by the natural phenomenon, so that the equipment such as the pump and the prime mover for driving the pump can be used. Can be omitted. Therefore, the equipment cost and running cost can be reduced.
