DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the pumping apparatus shown in FIG. 1, a closed container 3 is arranged between an upstream reservoir 1 at a high position and a downstream reservoir 2 at a low position for storing water. Is separated into a closed water chamber 5 on one side and an air expansion chamber 6 on the other side through a piston 4 that slides up and down. The water inflow pipe 7 for inflowing water from the reservoir 2 is connected, and the closed water chamber 5 is also connected.
Compressed air press-fitting in which a water supply pipe 8 for pumping water in the upstream reservoir 1 is connected, and compressed air for pressing the piston 4 into the air expansion chamber 6 to expand the internal volume of the air expansion chamber 6 is pressed. A container 9 is attached. This compressed air corresponds to the Japanese Patent Application No. 2-174 already proposed by the present inventor.
No. 532, Japanese Patent Application No. 3-210462 and Japanese Patent Application No. 3-2
The compressed air obtained by the method and apparatus for producing compressed air of No. 10463 is used. A first control valve 11 is provided between the compressed air press-fitting container 9 and the air expansion chamber 6, and by adjusting the first control valve 11, the compressed air press-fitting container 9 is removed from the air expansion chamber 6. It controls the amount of compressed air released into the interior. In the figure, reference numeral 12 is a second control valve provided in the water inflow pipe 7, reference numeral 13 is a third control valve provided in the water supply pipe 8, and reference numeral 1
Reference numeral 4 is a fourth control valve provided in the air vent pipe 10, and these valves control the flow of water or air. It should be noted that although not particularly shown, the movement direction of the piston 4 may be horizontal.

In the water pumping apparatus shown in FIG. 2, the compressed air pressurizing container 9 is attached to the upper part of the closed container 3. As described above, in this embodiment, the compressed air press-fitting container 9 is replaced by the closed container 3.
Since it is attached to the upper part of the device, the gravity of water in the piston 4 and the closed water chamber 5 is not applied compared to the device shown in FIG.
Therefore, the process of pushing the piston 4 by the compressed air discharged from the container 9 and expanding the inner volume of the air expansion chamber 6 is efficiently performed. In the figure, reference numeral 15 is a partition wall whose lower part is opened. This partition wall 15 has the compressed air pressurizing container 9 attached to the upper part of the closed container 3 and the water inflow pipe 7 as described above.
This is because the water supply pipe 8 is attached to the upper side of the closed container 3 so that the closed water chamber 5 connected to the water inflow pipe 7 and the water supply pipe 8 is also formed on the upper side of the closed container 3. The partition wall 15 is not necessary if the water inflow pipe 7 and the water supply pipe 8 are provided below the maximum descending position of the piston 4. Other configurations in this embodiment are the same as those in the embodiment of FIG.

In the pumping apparatus shown in FIG. 3, a closed container 3 is arranged between an upstream reservoir 1 at a high position and a downstream reservoir 2 at a low position, and the inside of this sealed container 3 is opened downward. The closed water chamber 5 and the air expansion chamber 6 are configured through a partition wall 15, and a water inflow pipe 7 for flowing water from the downstream reservoir 2 into the closed water chamber 5 is provided in the closed water chamber 5. Connect
Further, a compressed air pressure is formed by connecting a water pipe 8 for pumping the water in the closed water chamber 5 to the upstream reservoir 1 and further pressurizing compressed air for expanding the inner volume of the air expansion chamber 6 into the air expansion chamber 6. A container 9 is attached. In the apparatus of FIG. 3, the compressed air bubbles discharged from the compressed air pressurizing container 9 into the closed container 3 rise by buoyancy and collect in the air expansion chamber 6 separated by the partition wall 15. Reference numeral 16 is a second air expansion chamber, and the second air expansion chamber 1
Reference numeral 6 is an air chamber for storing bubbles of compressed air that could not be captured in the air expansion chamber 6. Other than that is the same as the apparatus of FIG.

In the pumping system shown in FIG. 4, a closed container 3 is arranged between an upstream reservoir 1 at a high position and a downstream reservoir 2 at a low position, and the inside of this closed container 3 is separated by a partition wall 15. To form a closed water chamber 5 and an expanded air storage container storage chamber 17,
A water inflow pipe 7 for inflowing water from the downstream reservoir 2 into the closed water chamber 5 is connected to the closed water chamber 5, and the water in the closed water chamber 5 is sent under pressure to the upstream reservoir 1. The water pipe 8 is connected. The inside of the expanded air storage container storage chamber 17 is provided with an air expansion chamber 6, and an expanded air storage container 18 having a stretchable structure is provided so that the internal volume of the air expansion chamber 6 can be increased or decreased by the internal air pressure. .. A compressed air press-fitting container 9 is attached to the expanded air storage container 18 via a first control valve 11, and an air vent pipe 10 for discharging the expanded air is attached via a fourth control valve 14. The apparatus shown in FIG. 4 is an improved version of the apparatus shown in FIG. 3, and the compressed air released from the compressed air pressurizing container 9 by the expanded air storage container 18 can be efficiently captured in the air expansion chamber 6. Is.

The operation of the apparatus shown in FIGS. 1 to 4 will be described. First, used water after power generation by a power generator (not shown) from the downstream reservoir 2 through the water inflow pipe 7 is closed water chamber 5.
The inside of the closed water chamber 5 is filled with water. All the air in the air expansion chamber 6 is removed from the air vent pipe 10 by opening the fourth control valve 14. The second control valve 12 and the fourth control valve 14 are closed, and the third control valve 13 is opened. The first control valve 11 of the compressed air press-fitting container 9 is attached to the air expansion chamber 6 by slightly opening it. 1 and 2 is the case where the piston 4 is used, the compressed air pressurizing container 9
Since the pressure of the compressed air released from is much larger than the water pressure in the closed water chamber 5, the piston 4 is pushed and the water is pushed up. The apparatus of FIG. 3 does not use a piston, and the bubbles of the compressed air discharged from the compressed air pressurizing container 9 rise in the water in the sealed water chamber 5 and accumulate in the air expansion chamber 6 while expanding the volume. Push up the water by that volume. In the device shown in FIG. 4, the air discharged from the compressed air pressurizing container 9 has an air expansion chamber 6 inside.
Enter into the expandable air storage container 18
The volume of the air expansion chamber 6 is increased and water is pushed up by that volume. In any case, water rises in the water supply pipe 8 by the volume of the compressed high-pressure air, and flows into the upstream reservoir 1 when the pipe is filled with water. When the release of air from the compressed air pressurizing container 9 is almost stopped, the third control valve 13 is closed, and the fourth control valve 14 of the air vent pipe 10 is opened to release the air.
The control valve 12 is opened to guide the water after power generation in the downstream reservoir 2 into the sealed water chamber 5. When all the air in the air expansion chamber 6 is released, the second control valve 12 and the fourth control valve 14 are closed, a new compressed air pressurizing container 9 is attached, and the third control valve 13 is attached.
By opening and repeating the same procedure as before, the water used after power generation can be sent to the upstream reservoir 1 and repeatedly used for power generation. This method means that the air expansion energy of the high-pressure air increases the energy of the gravity position of the water in the low position to the high place so that it can be used again for power generation.

5 to 8 show application examples of the present apparatus. FIG. 5 is an example in which an upstream water storage tank 1 and an underground water storage tank 2 are provided on the roof of a building and a small-scale power generation is performed by the same device as in FIG. Sewage treated water can be used as water. In addition, Figure 6 shows an underground reservoir 2 that temporarily stores floods in the city.
This is an example in which the above water is pushed up to the surface reservoir 1 and then naturally flowed down by the river. Further, FIG. 7 shows an example of pumping water from a river or an irrigation canal into an irrigation canal provided in the cultivated land in order to irrigate the arable land. Further, FIG. 8 is an example of hydroelectric power generation in which the ocean or lake is used as the downstream reservoir 2 and a reservoir constructed by constructing a dam in the valley of a nearby mountain is used as the upstream reservoir 1. In FIGS. 5 and 8, reference numeral 20 indicates a generator. The description of the reference numerals in FIGS. 5 to 8 is the same as in FIG.

[0013]

According to the present invention, the energy of the position of water is increased by pushing the water in the low position to the high position by using the energy of compressed air. It is one application example to generate the same water over and over again by returning the used water from the hydroelectric power generation to the upstream reservoir again. Of course, it can also be used when the hydroelectric power generation facility is installed. In particular, the use of seawater lake water shown in FIG. 8 greatly expands the range of selection of points suitable for power generation. In addition to power generation, for example, when it is desired to pump water to a high place in a low-lying area, it can be used in the same way as a pump, so it can be used in a wide range of applications such as a substitute for electric power. As an energy source, it will be a powerful tool for solving the problems of pollution of the global environment and the energy problems that can be the limiting factor for the growth of civilized society.
