In the figure, 20 is an adjusting screw (fixing tool) for fixing the discharge cylinder at a predetermined position of the pumping cylinder.

Next, the use of the water pumping device 19 based on the above embodiment will be described.

The base 1 of the water pumping device 19 is attached to the bottom of the water tank 36. Next, pressurize air from the air supply hose 17 in the direction of arrow 21 and
Pressurized air is injected into the intermittent air supply device 6 from 16. The injected pressurized air enters the outer chamber 9 and passes through the communication hole 15 to reach the outer chamber 9.
And the water accumulated in the intermediate chamber 8 and discharged from the outer chamber 9 and the intermediate chamber 8. When the pressurized air is sent again and the water level reaches 22, the accumulated pressurized air enters the inner chamber 7 as indicated by the arrow 23, and the water in the inner chamber 7 is discharged from the communication hole 11. While rising,
Further, it is discharged from the communication hole 11 into the pumping cylinder 3 as shown by an arrow 24. At this time, the pressurized air becomes air bubbles 25 that are fully spread in the cross section of the water pump 3, rises in the direction of the arrow 26, and is pushed by the air bubbles 25 to move the water in the water pump 3 from the discharge port 5 to the arrow 27. Push in the direction. Further, due to the rising force of the bubbles 25, water is sucked into the pumping cylinder 3 through the suction port 2 at the lower end of the pumping cylinder 3 as shown by an arrow 28. Further, the bubbles 25 rise in the pumping cylinder 3, are discharged from the discharge port 5 in the direction of the arrow 27 to the outside of the pumping cylinder 3, and rise toward the water surface.

Further, when the air in the intermittent air supply device 6 is discharged as bubbles 25, water enters the intermittent air supply device 6 through the suction port 18 as indicated by the arrow 29, and the outer chamber 9, the intermediate chamber 8 and The inner chamber 7 is again filled with water as in the beginning.

In the above description, the bubbles 25 in the pumping cylinder 3 are intermittently supplied at intervals determined by the capacity of the intermittent air supply device 6 and the air supply capacity of the pressurized air, so that the water absorption is intermittently accelerated and continuously. It is sucked into the pumping cylinder 3.

When the above operation is repeated, bubbles 25 are intermittently generated in the pump cylinder 3.
Occurs, water near the bottom of the water is pumped and discharged from the discharge port 5, so that the water in the water tank circulates.

Therefore, the pumping device 19 is placed on the bottom of the water tank 36 as shown in FIGS. 4 and 5, the adjusting screw 20 is loosened, and the discharge cylinder 4 is moved up and down.
If the discharge cylinder 4 is fixed so that the discharge port 5 is located near the water surface, and the pumping device 19 is installed at the corner of the square water tank 36, it will be shown in the direction of arrows 30 and 30 in all planes, and will also be shown. The water in the water tank is vertically convectively circulated over the entire depth like 31, 31. Furthermore,
Aerated by bubbles 25. If the pumping device 19 is installed at the edge of the circular water tank 37 as shown in FIG.
As in 32, the water in the water tank is vertically convected and circulated.

In the above description, the capacity of the intermittent air supply device and the air supply capacity of the pressurized air are determined according to the capacity of the installation location and the like. Therefore, although the pumping device 19 is installed in the aquarium in the above-mentioned embodiment, if the pumping device 19 has a large size, it can be used in aquaculture ponds, lakes, reservoirs and the like.

Further, in the above-mentioned embodiment, the pumping cylinder 3 and the discharge cylinder 4 are square cylinders, but as shown in FIG. 3, the upper part may be a circular cylinder to form the pumping device 19a. In the case of the pumping cylinder 3a and the discharge cylinder 4a which are round cylinders, bubbles 25 are easily formed, and the direction of the discharge port can be freely adjusted in a desired direction. In the above, a locking hole for locking the tip of the adjusting screw 20 or a vertical locking recess is provided on the outer wall of the pumping cylinder 3 so that the discharge cylinder 4 can rotate at a predetermined angle (for example, 30 degrees). It is also possible (not shown).

Further, in the above-described embodiment, the discharge cylinder 4 provided with the discharge port 5 is fitted to the pump cylinder 3, but the discharge cylinder 4 is not used but the pump cylinder 3 is used.
It is also possible to provide a discharge port 5 on one side wall of the upper part (not shown).

(Second Embodiment) Next, another embodiment of the present invention will be described with reference to FIGS. 7 and 8.

The circular pumping pipe 3a of the pumping device 19a formed in the first embodiment.
In addition, the intermittent air supply device 6 and the intermittent air supply device having a similar structure to the target
Install 6a.

The intermittent air supply device 6a includes an inner chamber 7a, an intermediate chamber 8a, and an outer chamber 9a, and a pumping cylinder wall 10a between the pumping cylinder 3a and the internal chamber 7a has a communication hole 11a in the upper part. Further, a partition wall 12a between the inner chamber 7a and the intermediate chamber 8a is provided with a communication hole 13a in the lower portion, and a partition wall 14a between the intermediate chamber 8a and the outer chamber 9a is provided with a communication hole 15a in the upper portion. ing. A water inlet 18a is provided at the lower end of the outer chamber 7a. Through holes 33 and 33a are provided at the upper ends of the side walls of the intermediate chambers 6 and 6a, respectively, and are connected by a communication pipe 34 to form a pumping device 35.

The method of using the water pumping device 35 based on the above embodiment is the same as that of the first embodiment
Is the same as. That is, the pressurized air is indicated by the air supply hose 17.
The air is sent in the direction of 21, and pressurized air is injected into the intermittent air supply device 6 from the air supply port 16. The injected pressurized air enters the outer chamber 9, passes through the communication hole 15, the communication pipe 34, and the communication hole 15a, accumulates in the outer chambers 9 and 9 and the intermediate chambers 8 and 8a, and drains the water in each chamber. To do. Further, when pressurized air is fed in, the pressurized air is discharged into the pumping pipe 3a through the communication holes 13, 13a, 11, 11a as in the case of the first embodiment, and bubbles 25a are generated, which are discharged from the discharge port 5. It is discharged as shown by arrow 27. Therefore, as in Example 1, the water near the bottom of the water is pumped as shown by arrows 28 and 28 and discharged from the discharge port 5, so that the water in the water tank circulates.

In the above, since the intermittent air supply devices 6 and 6a are connected by the connecting pipe 34, the pressurized air that has been fed is simultaneously discharged from the connecting holes 11 and 11a into the pumping cylinder 3a. Further, in the above-described embodiment, the capacity of the intermittent air supply device is doubled as compared with the first embodiment, so that the pumping amount is also almost doubled.

In the above embodiment, the intermittent air supply devices 6 and 6a are located symmetrically with respect to the pumping cylinder 3a, but they may be installed at other positions.

(Effect of the device) Since this device has a discharge port that is oriented horizontally in the upper part of the pumping pipe, the water absorbed from the lower end of the pumping pipe is discharged in one direction, so install it at the edge of a tank or lake. There is an effect that can be used. Therefore, there is an effect that the maintenance and inspection of the water pumping device can be facilitated. Next, if the intermittent air supply device is provided on one side and is on the opposite side to the discharge port, it is rational when installing on one side of the water tank.

Further, when the water level changes, there is an effect that the height of the discharge port can be adjusted to properly maintain the water fog at the discharge port.
