Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to lakes, ponds, dams,
The present invention relates to a water circulation apparatus suitable for purifying closed water bodies such as a basin.

[0002]

2. Description of the Related Art A method of circulating water in a water body for purifying water quality in a closed water area (hereinafter, simply referred to as "water area") such as lakes, ponds, dams, and reservoirs is known. As a circulating device for a water area that performs this circulating method, a pump-type circulating device that generates a circulating flow in a water region by a discharge jet of a submersible pump or a propeller-type circulating device that generates a circulating flow in a water region by rotating a propeller in water by a submersible motor Generally referred to as underwater mixers).

[0003]

The conventional pump-type circulating apparatus and the propeller-type circulating apparatus use a submersible motor as a prime mover, and therefore consume a large amount of power. In addition, since it has a plurality of moving parts (operating parts), the mechanical loss increases, which hinders a reduction in running cost.

[0004] Therefore, an object of the present invention is to provide a circulating device for a water area in which running power can be reduced by suppressing power consumption and mechanical loss to a small level.

[0005]

In order to achieve the above object, a water circulating apparatus according to the present invention is provided with a vertically extending pumping pipe and a water pipe circulating below the pumping pipe. Forming a bubble pump with a water guide pipe extending to the air pump means for blowing air for lift into the water pump pipe,
The water in the water area is sucked into the water pipe along with the pumping inside the water pipe by the ejection of the air for lift, and the water in the water area is directed toward the opposite side of the direction of extension of the water pipe with the suction. The invention is characterized in that the bubble pump is installed in the water area so as to generate a flow.

According to the present invention, when the air for lifting is ejected into the pumping pipe by the air ejecting means, the air mixes with the water in the pumping pipe to reduce the specific gravity of the water in the aeration part, As the air (bubbles) rises, a lift action occurs inside the pumping pipe. The water in the pumping pipe is drained to the outside by the synergistic action of the specific gravity reducing action and the lift action. The water in the water area is sucked into the water pipe with the drainage from the water pipe.

[0007] As the water in the water area is sucked into the water pipe, a flow of the water in the water area is directed toward the opposite side of the direction in which the water pipe extends, that is, a flow is directed toward the suction port of the water pipe. Such a flow of water causes the water in the water area to circulate, and by continuing the circulation, the water in the water area can be circulated to purify the water quality.

On the other hand, by limiting the moving part (operating part) to only the air blowing means, power consumption and mechanical loss can be reduced.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an embodiment of the present invention in partial cross section, and FIG. 2 is a plan view of FIG. In these figures, a bubble pump 1 is provided with a water pump 2
And a water pipe 3 and an air jetting means 4, and are mounted and fixed on a gantry 6 installed at a bottom 5A of a water body 5 such as a lake or a pond.

The pumping pipe 2 is a cylindrical body which is located at the base end of the bubble pump 1 and has a vertical axis opening at the upper end. The upper end opening 2A faces slightly above the water surface WL of the water area 5. .

The water pipe 3 has a distal end (downstream end) communicating with a lower end (upstream end) of the water pump 2 and a tube extending horizontally from the water pump 2 toward the upstream side. The rear end suction port (upstream end suction port) 3A is directed to the upstream side while being submerged in the water area 5. That is, the side surface shape of the bubble pump 1 is L-shaped.

The air jetting means 4 is for jetting lift air from the lower end of the pumping pipe 2, and has an air supply pipe 40 whose upper end is open upward facing the lower end of the pumping pipe 2. An air supply source 41 formed by an electromagnetic air compressor to which an inlet of the air supply pipe 40 is connected;
An outlet is connected to the air supply source 41, and an inlet is opened slightly above the water surface WL of the water area 5; an air introduction pipe 42 that opens; a power supply device 43 that supplies power to the air supply source 41; Solar cell 4 for supplying power to power supply device 43
The power supply device 43 includes a control unit provided with an inverter circuit that converts a DC current from the solar cell 44 into an AC current, a controller that sets and controls the power supplied to the air supply source 41, and a storage battery. Composed and air supply 4
1, the power supply device 43, the solar cell 44, and the like are appropriately installed on the ground around the water body 5.

The air supply source 41, the power supply unit 42, the solar cell 43, and the like may be mounted on a floating body (not shown) floating in the water area 5 instead of the above-mentioned ground around the water area 5. When mounted on a floating body, it is necessary to fix the floating body to the shore of the water area 5 via a rope or a wire so that the floating body does not move due to wind, waves, or the like. Also,
Air supply source 41 composed of an electromagnetic air compressor
The existing commercial AC power supply may be used instead of the solar cell 43 for power supply to the power supply.

According to the above configuration, an electromotive force is generated by irradiating the solar cell 44 with a predetermined amount of light, and this electromotive force is supplied to a control unit (not shown) of the power supply device 43.
The supplied DC electromotive force is converted into AC by an inverter circuit of a control unit, and a predetermined amount of power preset by a controller is supplied to an air supply source 41 formed by an electromagnetic air compressor to drive the air supply source 41.

The driving of the air supply source 41 causes the pumping pipe 2
The air for lift squirts upward from inside from inside. The jetted air becomes bubbles and mixes with the water in the pumping pipe 2 to reduce the specific gravity of the water in the aeration section, and a lift action is generated inside the pumping pipe 2 as the jetting air (bubbles) rises. . The water in the pumping pipe 2 is drained to the outside by the synergistic action of the specific gravity reducing action and the lift action. With the drainage from the pumping pipe 2, the water in the water area 5

When installed on the R and operated at the same time, the water in the water area 5 is sucked into the water pipes 3 of the bubble pumps 1, 1,..., And the water in the water area 5 on the upstream side of the bubble pumps 1, 1,. A flow indicated by an arrow f toward the suction port 3A is generated at this time, and such a flow of water f causes the water in the water area 5 to circulate F. By continuing the circulating flow F, the water in the water area is circulated to improve the water quality. Can be purified.

On the other hand, the moving part (operating part) is limited to only the air supply source 41 constituted by the electromagnetic air compressor of the air blowing means 4, so that it is compared with a conventional pump-type circulating device or a propeller-type circulating device. , Power consumption and mechanical loss are kept small. Therefore, the running cost can be reduced.

Are installed on the endless line R at appropriate intervals with their pumping tubes 2 positioned at the downstream end. However, the installation number and the installation pattern of the bubble pumps 1 can be arbitrarily changed according to the size and shape of the water area 5.

[0020]

As described above, since the water circulation apparatus according to the present invention is constituted, the following special effects can be obtained.

That is, as the water in the water area is sucked into the water pipe by the operation of the bubble pump, the water in the water area flows toward the opposite side of the extension direction of the water pipe, that is, flows toward the suction port of the water pipe. A flow occurs, and such a flow of water causes the water in the body of water to circulate, and by continuing the circulation,
The water quality can be purified by circulating the water in the water area. In addition, since the moving part (operating part) is limited to only the air blowing means, power consumption and mechanical loss can be suppressed smaller than in a conventional circulating device, and running costs can be reduced.
