Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power system for a water pumping apparatus and a solar cell apparatus, which uses a solar battery as a motor power source of a compressor of the water pumping apparatus.

[0002]

2. Description of the Related Art Conventionally, an intermittent air pumping device has been used as a drainage device for dams, lakes, swamps, harbors and the like. The intermittent air pumping device intermittently applies pressurized air to the lower part of a pumping cylinder installed upright in water, raises bubbles in the pumping cylinder, and vertically convects the water area. A compressor is exclusively used to apply the air, and a motor is exclusively used as a driving force of the compressor. Therefore, in order to install a pumping pipe and to flush the water, it is necessary to drive the motor for the compressor operation, so an electric wire is erected during the drainage of the lake in the mountains and the swamp.

[0003]

As described above, a motor for driving a compressor is required to send the pressurized air to the water area that requires the fresh water, but in the case of lakes or bays in the mountains, etc. Requires an electric wire to be installed over a considerable long distance (for example, ten kilometers or more), which causes a problem such as a high installation cost or the necessity of maintenance.

[0004]

However, the present invention has solved the above-mentioned conventional problems by using a solar cell as a power source for a motor.

That is, according to the present invention, there is provided a power system for a water pumping apparatus, characterized in that the output side of a solar cell is connected to a circuit of a compressor motor of the water pumping apparatus. Another invention is to connect a controller to the circuit of the compressor motor of the water pumping device, and to the output side of the solar cell to this controller,
A power system for a water pumping device, characterized in that it is connected to the output side of a storage battery. Next, another invention is that a solar cell is laid on a building on land. Regarding the installation of solar cells, the solar cells are laid on a structure above water. Still another invention is that, on a floating body, vertical axis rotating means,
A solar cell device of a power system for a pumping system, wherein a solar cell panel is installed through a horizontal axis rotating means, and a control device for the vertical axis rotating means and the horizontal axis rotating means is additionally provided.

[0006] In the above, the solar cell may be of a stationary fixed type or a computer controlled moving type. In the case of the fixed method, the irradiation angle of sunlight on the solar cell changes with time, but in the case of the moving method, the irradiation angle can be kept substantially constant and the power generation efficiency can be improved. In addition, since it is not possible to generate electricity at night, use a storage battery,
In the daytime, it is also possible to charge the storage battery with extra electricity for continuous operation day and night. Whether to perform the intermittent operation or the continuous operation is determined in consideration of the cross-sectional shape of a dam, the number of pumping equipment installed, the degree of pollution, and the like. The required capacity of the solar cell is 0.2 kW
Because it is ～22Kw, footprint 2m ² 200 m ²
Will be needed. Therefore, the diameter is 50c, considering some safety factor.
In the case of a compressor motor having a pumping cylinder of m and a length of 10 m, at least 7.5 kW is required.

[0007]

According to the present invention, the solar battery or the solar battery and the storage battery are required as the power source of the motor. Therefore, even when the water is drained in the mountains or the bay without electricity, no overhead wire is required. The object can be achieved even if the hose for feeding the compressed air is significantly shortened.

Further, according to the system of the present invention, the running cost can be remarkably reduced.

[Embodiment 1] In the embodiment of FIG. 1, the output of the solar cell 1 installed on the ground or on the water is input to the circuit of the motor 2, and the motor 2
The compressor 3 is driven by the rotation of the pump, and reference numeral 4 in the drawing is a pump.

An air chamber 5 is fitted to the lower portion 12 of the pumping cylinder 4 as shown in FIG. The pumping cylinder 4 is vertically installed slightly below the water surface 8 (1 m to 20 m below) by a weight 6 and a floating chamber 7 provided above the pumping cylinder 4.

When pressurized air is fed into the air chamber 5 of the pumping cylinder 4 as shown by the arrow 9, the air in the air chamber 5 causes
The water level drops. When the water level descends to the through hole 11 of the inner cylinder 10, the air passes through the inner cylinder 10, the partition cylinder 12 and the through holes 11, 13, 14 of the pumping cylinder 4 as indicated by arrows 15, 16, 17, and the air bubbles 18 enters the pumping cylinder 4 and bubbles 18
Is lifted as indicated by arrow 19 by buoyancy, and accordingly, the water at the bottom of the pumping cylinder 4 is sucked up as indicated by arrow 20. On the other hand, the water discharged from the upper end of the pumping cylinder 4 as indicated by arrow 21 once jets out as shown by arrows 22 and 22, rises, and then diffuses radially as indicated by arrows 23 and 23. Therefore, centering on the pumping cylinder, arrows 21, 22, 2
Up-and-down convection such as 3, 24, 25, and 20 is generated, and the water near the water surface descends to the bottom of the water and mixes, whereby the dissolved oxygen amount is rapidly improved. There, aerobic microorganisms reproduce and decompose organic matter, and the water-bloom is caught in the bottom of the water, loses its vitality, and eventually die.

[Embodiment 2] The embodiment of FIG. 2 is a solar cell 1 and a storage battery 2.
6 is used as a power source for the motor used in the compressor.

That is, the output of the solar cell 1 and the output of the storage battery 26 are controlled and input to the circuit of the motor 2 via the device, the compressor 3 is driven, and the pressurized air is supplied to the air chamber 5 of the pumping cylinder 4.
Send to. When the electric power of the solar cell 1 is surplus, the surplus portion is used by the controller 27 to charge the storage battery 26, and when the output of the solar cell 1 is lower than the required power of the motor 2, the storage battery 26 supplies it. It was done. Since the output of the solar cell 1 decreases or disappears at night or in rainy weather, the output from the storage battery 26 becomes the main force. In the above, the driving of the motor may be interrupted at an appropriate time during the night, taking into consideration the power generation, the storage battery capacity, the cleaning capacity, and the like.
Regarding the control, the controller 27 may be provided with a sequence required for control in advance, and may be automatically controlled depending on the season.

According to the present invention, since the output side of the solar cell is connected to the circuit of the compressor motor of the water pumping apparatus, the compressor can be driven by the motor even in the mountains where there is no electric equipment or on the water. There is. Therefore, there is no need for power transmission equipment, so not only the cost of solar power generation equipment is much higher than that of ordinary solar power generation equipment, but there is also the effect of reducing the total cost of clean water such as the electricity cost for subsequent operation is free.

Further, if the solar cell is installed on the water, there is an effect that the cost required for air supply such as an air supply hose can be reduced.
