DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.

The pump 1 shown in FIGS. 1 and 2 converts deep water containing abundant nutrients present in a relatively deep place such as the sea and having a low temperature and a small amount of bacteria to the vicinity of the sea surface 2 as a water surface. It is a pumping device.

As shown in FIGS. 1 and 2, the pump 1 has a buoy 10, a floating body 11, a compressed gas generator 12,

The cylinder 17 is provided along the vertical direction of the buoy 10 floating on the sea surface 2 in the longitudinal direction. A rod 19 is connected to the piston 18 on its upper surface 18a so as to be swingable in all directions.

The rod 19 has one end connected to the upper surface 18a of the piston 18 so as to be swingable in all directions.
The other end penetrates the upper wall of the cylinder 17 and protrudes from the upper surface 10 a of the buoy 10.

The seesaw 16 is attached to the upper surface 10a of the buoy 10. The seesaw 16 includes a fulcrum 20 and a seesaw rod 21. The fulcrum 20 is attached to the upper surface 10a of the buoy 10 and supports an intermediate portion 21a of the seesaw rod 21 so that the seesaw rod 21 can swing in all directions.

The seesaw rod 21 is formed in a rod shape, and has one end connected to the rod 19 so that the rod 19 can swing in all directions. In addition, the seesaw rod 21 has a floating body 11 at the other end via a rod 22.
It is connected to. The rod 22 is swingably connected to the seesaw rod 21 and the floating body 11 in all directions.
With the above-described configuration, the buoy 10 can swing freely following the waves 4 generated in the sea surface 2 in all directions.

The tube 13 has a first tube 23 and a second tube 24. The tube 13 comprises a first tube 23 and a second tube 24
Are connected to each other in series, and are provided through the buoy 10. The tube 13 has one end 1
3a is open above the water surface, and the other end 13b extends toward the seabed 3. The other end 13b is open to the sea as underwater. A first pipe 23 is located on the sea floor 3 side, and a second pipe 24 is arranged on the sea surface 2 side. The second tube 24 has a larger diameter than the first tube 23.

In the illustrated example, the pipe 13 is formed to extend about 200 m below the sea surface 2. The first tube 23 has an inner diameter of 200 mm. The second tube 24 has an inner diameter in the range of 200 mm to 250 mm.

The cylinder 17 and the pipe 13 are connected to each other by the pipe 2
5 are connected. The pipe 25 has one end 25a connected to the bottom wall of the cylinder 17 and the other end 25a.
b is connected in the middle of the tube 13. The other end 25b is
It is connected to the first tube 23.

The pipe 25 is provided with a check valve 26. The check valve 26 allows the fluid to flow only in the direction from the cylinder 17 to the pipe 13. In the illustrated example, the pipe 25 has an inner diameter of 150 mm to 20 mm.
0 mm and the other end 25b is the first
The pipe 23 is connected to a position within a range from 50 m to 70 m below the sea surface 2.

A check valve 27 is provided in the cylinder 17. The check valve 27 allows the fluid to flow only in the direction from the cylinder 17 to the pipe 13.
Further, a supply pipe 28 opened to the atmosphere is connected to the upper end of the cylinder 17. The supply pipe 28 is provided with a check valve 29. The check valve 29 allows the fluid to flow only from the atmosphere toward the cylinder 17.

The above-mentioned one floating body 11, one compressed gas generating part 12 and one pipe 13 constitute a pump unit 30. The water pump 1 includes a plurality of pump units 30. In the illustrated example, the pump 1
Has 12 sets of pump units 30. These pump units 30 are independent of each other.

According to the above-described configuration, the water pump 1
Moored by the mooring line 14 and connected to the seabed 3,
And the buoy 10 is installed in a state of floating on the sea surface 2. When a wave is generated on the sea surface 2 as indicated by reference numeral 4 in FIGS. 1 and 2, the floating body 11 shakes. This movement of the floating body 11 is transmitted to the piston 18 via the rod 22, the seesaw rod 21 and the rod 19.

The piston 18 is displaced in the vertical direction due to the movement of the floating body 11 transmitted through the seesaw rod 21 or the like. When the piston 18 is displaced from the bottom dead center toward the top dead center and is located near the top dead center, the atmosphere such as gas is sucked into the cylinder 17 through the check valve 29 and the supply pipe 28. When the piston 18 is displaced from the top dead center toward the bottom dead center, the air in the cylinder 17 is compressed to generate a compressed gas. Thus, the compressed gas generator 12
Generates compressed gas in conjunction with the movement of the floating body 11.

This compressed gas is supplied to the middle of the pipe 13 via the check valve 27, the pipe 25, the check valve 26 and the like.
In the illustrated example, the pressure of the compressed atmosphere as the compressed gas supplied into the pipe 13 at this time is 5 kg / c
The pressure ranges from m2 to 7 kg / cm2.

Since the compressed air supplied in the middle of the pipe 13 gradually decreases as the water pressure in the pipe 13 moves toward the sea surface 2, as shown by reference numerals S1 to S3 in FIG. It gradually expands as it rises toward the sea surface 2 in the interior. For this reason, the flow velocity in the pipe 13 gradually increases toward the sea surface 2, and an upward flow occurs in the pipe 13.

Further, in the so-called gas-liquid two-phase flow section in which air is present in the pipe 13, its specific gravity is smaller than the specific gravity of seawater as water outside the pipe 13. For this reason, deep water flows into the pipe 13. Therefore, a further upward flow is generated in the pipe 13.

By the upward flow, water such as seawater as deep water is sucked into the pipe 13 from the other end 13b of the pipe 13, and rises in the pipe 13 toward the one end 13a. Then, the water is discharged from the one end 13 a of the pipe 13 to the sea surface 2.

According to the present embodiment, the floating body 11 is provided so as to be freely oscillated by the wave 4 on the sea surface 2, and the compressed gas generator 12 generates the compressed gas in conjunction with the movement of the floating body 11.
The generated compressed gas is supplied to the middle of the tube 13 and the buoyancy of the compressed gas causes the other end 13b of the tube 13 to flow.
, And pumps water such as deep water toward one end 13a. As described above, since the pump 4 uses the wave 4 on the sea surface 2 as a power source when pumping deep water, there is no need to use external power such as electric power.

Further, since the pump 4 pumps deep water by the waves 4, it requires less manual operation and is preferable for cultivation and fisheries where fish 5 as aquatic organisms gather. Since the pump units 30 are independent of each other,
Pumping can be performed with small wave power, and even if one pump unit 30 fails, deep water can be pumped.

FIGS. 3 and 4 show a second embodiment.
The same components as those in the first embodiment described above are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIGS. 3 and 4, the water pump 1 of the present embodiment has only one pipe 13 and only one storage tank 31 as a storage part. As shown in FIG. 3, the tube 13 is
It branches into a plurality of branch pipes 32 on the a side. These branch pipes 32 are formed to extend toward the outer peripheral direction of the buoy 10. These branch pipes 32 are arranged at equal intervals along the circumferential direction of the buoy 10. In the illustrated example, three branch pipes 32 are provided.

The storage tank 31 is connected to each cylinder 17 through a pipe 33 and
Is connected in the middle of the first tube 23 of the tube 13.
The pipes 33 and 34 are provided with check valves 35 and 36, respectively. The check valve 35 provided in the pipe 33 allows the fluid to flow only in the direction from the cylinder 17 to the storage tank 31. Check valve 36 provided in pipe 34
After the pressure in the storage tank 31 reaches a predetermined pressure, the fluid flows only from the storage tank 31 toward the pipe 13.

With the above-described configuration, the compressed gas generated in the cylinder 17 by the movement of the floating body 11 is
3 and is temporarily stored in the storage tank 31 via the check valve 35. After reaching a predetermined pressure, the compressed gas stored in the storage tank 31 is supplied to the middle of the pipe 13.

According to the present embodiment, as in the first embodiment, since deep water is pumped by the waves 4, there is no need to use external power such as electric power, and there are few operations that require humans, and as aquatic organisms. It is preferable for the cultivation fishery where fish 5 and the like gather.

A plurality of compressed gas generators 12 are provided. The compressed gas generated by these compressed gas generators 12 is temporarily stored in a storage tank 31, and then the compressed gas is supplied to the middle of the pipe 13 to be supplied to the deep water. Pump. As described above, since the compressed gas is once stored in the storage tank 31 and then supplied to the pipe 13, a relatively large amount of compressed gas is supplied into the pipe 13, so that a larger amount of deep water can be pumped up Becomes

FIG. 5 shows a third embodiment, in which the same components as those in the above-described first and second embodiments are denoted by the same reference numerals, and description thereof will be omitted.

The water pump 1 of the present embodiment includes a buoy 10
Are urged toward the seabed 3 against the buoyancy thereof by mooring lines 14a as urging means. Further, the water pump 1 of the present embodiment includes a plurality of pump units 30 each including one floating body 11, one compressed gas generator 12, and one pipe 13.

According to this embodiment, as in the first embodiment, since deep water is pumped by the waves 4, there is no need to use external power such as electric power, and there are few operations that require humans, and as aquatic organisms. It is preferable for the cultivation fishery where fish 5 and the like gather. Further, it is possible to pump water with a small wave power, and even if one pump unit 30 fails, it is possible to pump deep water.

Further, in the water pump 1 of the present embodiment, the buoy 10 is urged toward the seabed 3, so that the buoy 10 and the floating body 11 oscillate in substantially the same phase by the waves 4 on the sea surface 2. Is suppressed. Therefore, the relative movement between the buoy 10 and the floating body 11 is suppressed from being reduced, and the deep water can be more efficiently pumped by the waves 4 on the sea surface 2.

Further, in the illustrated example, the pump 1 having a plurality of pump units 30 is shown. However, like the pump 1 shown in the second embodiment, only one pipe 13 and only one pump 13 are provided. The buoy 10 may be provided by biasing toward the seabed 3 by the mooring cable 14a.

In this case, in addition to the above-described effects of the present embodiment, since the compressed gas is once stored in the storage tank 31 and then supplied to the pipe 13, a relatively large amount of compressed gas can be supplied into the pipe 13. , It is possible to pump a larger amount of deep water.

[0042]

According to the pump of the present invention, the floating body is provided so as to be able to swing by the wave of the water surface, and the compressed gas generator generates the compressed gas in conjunction with the swing of the floating body. By supplying this compressed gas to the middle of the pipe, water is pumped from the other end of the pipe extending toward the bottom to one end opened to the water surface. Therefore, since the pump uses the wave on the water surface as a power source when pumping water, there is no need to use external power such as electric power.

Further, the pump has a plurality of compressed gas generators. The compressed gas generated by these compressed gas generators is temporarily stored in the storage unit, and then the compressed gas is supplied to the middle of the pipe to supply water. Pump it up. Since this pump uses water waves as a power source when pumping water, there is no need to use external power such as electric power, and since the compressed gas is once stored in the storage section and then supplied to the pipe, it is relatively large. By supplying the compressed gas into the pipe, a larger amount of water can be pumped.

Furthermore, the pump does not need to use external power such as electric power, and the buoy is urged toward the bottom of the water, so that the waves on the water surface cause the buoy and the floating body to oscillate substantially in phase with each other. Is suppressed. For this reason, since the relative motion between the buoy and the floating body is suppressed from being reduced, it is possible to pump water more efficiently by the waves on the water surface.
