DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the operation of the present invention using the energy of wave, which is a clean natural energy, in today's world where global warming, destruction of the global environment, depletion of energy resources, etc. have become major problems. By replacing the water of the ocean, dams, lakes, etc. up and down, the effect as a device for preventing global warming, fertilization of the sea area, a device for preventing environmental destruction, and floating deep sea cold water on the sea surface, Since carbon dioxide (CO ₂ ) can be absorbed by the cold water or phytoplankton contained in the water,
The present invention relates to a device for pumping seawater and the like using wave energy for preserving and improving the global environment.

[0002]

2. Description of the Related Art Generally, the cultivation of seafood and seaweeds,
In biomass, biotechnology, marine ranch, measures to prevent global warming, and purification of seawater, surface seawater is created by floating deep water (bottom water) in the bottom layer of the ocean, etc., on the sea surface and mixing it with surface water. Temperature drop, phytoplankton contained in cold water and deep water
O ₂ ) is absorbed to lower the concentration of carbon dioxide in the atmosphere, fertilization of the sea area, increase of marine resources, etc.
It is generally widely known that low-oxygen water in the bottom layer is floated on the sea surface, mixed with surface water using ocean currents and waves, and purified by contacting air in the atmosphere. I have.

[0003] For this reason, conventionally, it has been general to use a driving source such as an electric motor or an internal combustion engine to take in this deep water (bottom water).

On the other hand, as a means for pumping seawater or the like utilizing natural energy, a device for drawing water using wave power is a "seawater pumping apparatus" invented by the same inventor as the present invention.
(Japanese Patent Publication No. 6-72594) is generally well known. As shown in FIG. 9, the seawater pumping device 41 floats on the sea surface, and a pumping pipe is provided substantially at the center thereof.

By moving the float and the pumping pipe up and down by the wave up and down, it is pumped to the sea surface by the action of the check valve.

[0005] Since the pumping device 41 for seawater or the like operates using the energy of waves, it does not require any energy source that causes environmental pollution such as petroleum.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view showing an embodiment of the apparatus for pumping seawater or the like using the energy of waves according to the present invention. As shown in FIG. 1, a pumping apparatus 1A for seawater or the like utilizing wave energy (hereinafter referred to as a pumping apparatus) 1A is moored on a sea or in a closed water area such as a harbor using a mooring line such as a chain or a rope. ing.

In the pumping apparatus 1A, a pumping pipe 2 is attached to a substantially central portion of a floating body 1 that floats on the sea surface 3 and moves up and down following waves to penetrate therethrough. It is integrated. The lower end opening 2b extends toward the seabed 4 side. At the upper end of the upper opening 2a of the pumping tube 2, a check valve valve seat 5 is provided so as to warp outside the opening 2a, and a check valve 6 is provided thereon. . A portion above the check valve 6 is defined as a main tank 7, and the water surface of the tank is defined as 7 a, and this tank is integrally connected to the floating body 1. The check valve 6 has a valve plate 8 and a weight 9 and a floating body 10 integrated with each other.
The valve plate 8 does not fall over due to the center of gravity.

A guide 11 is provided outside the valve plate 8, and a stopper 12 is fixed to an upper end of the guide 11 so that the valve plate 8 cannot move upward any more. The guide 11 keeps a certain gap,
Made of rods, steel bars, etc., the bottom water near the seabed 4 is 2b, 2a
, The check valve 6 is opened, and it is possible to enter the main tank 7 through the gap of the guide 11. A flexible flexible hose 13 is provided below the pumping tube 2 so that the lower portion of the pumping tube 2 does not reach the seabed even if the floating body 1 abnormally drops during a large wave.

Drainage pipes 14 are connected to both side walls of the main tank 7 and extend radially in the radial direction, and at the same time, penetrate the side plate of the floating body 1. The water in the main tank 7 can be drained to the outside of the floating body 1 through the drain pipe 14, but the external water cannot flow back into the main tank 7 by the action of the check valve 15.

The ceiling 16 at the upper part of the drain pipe 14 has an upward slope toward the center of the apparatus, that is, toward the main tank 7, so that the water in the main tank 7 drains from the drain pipe 14 to the outside of the apparatus. The structure is such that bubbles or bubbles contained in air or water above the water surface 7a in the main tank are not easily entrained. Even if bubbles or bubbles contained in the water in the main tank 7 get caught in the drain pipe 14 due to the shaking of the apparatus during a big wave or the like, the bubbles are transmitted to the drain pipe 14 by using the gradient of the ceiling 16. This is taken out by raising it while raising it, and is immediately returned to the main tank 7 so that the bubbles and bubbles can escape above the tank.

Below the floating body 1, in the vicinity of the attachment of the pumping tube 2, a mounting bracket 17 for a chain or a mooring line is fixed, and a chain or a mooring line 18 is connected to this, and the other lower end is connected to an anchor 19 or the like. Tied. This pumping device is moored by the above-described method, a floating body 1 is placed on the sea surface, and a pumping tube 2 is suspended just below the floating body 1. A marker lamp 20 and the like are also provided above the floating body 1 and are provided with means that do not hinder navigation of other ships or the like.

The check valve 15 provided at the discharge port 14a at the end of the drain pipe 14 is provided with a protective frame 21, a protective fence 22 and the like as means for preventing operation failure or failure due to unexpected large waves or the like. It is assumed that the check valve 15 is provided to protect the check valve 15. The wastewater discharged from the outlet 14a of the drainpipe 14 hits the lattice 23 or a crushing device and is crushed, and then discharged near the sea surface.

Next, the operation will be described. Now, suppose that the pumping device is in the valley of the wave, and the bottom water near the seabed 4 flows into the main tank 7 through the pumping pipe 2 and the check valve 6, and the water level reaches 7a and the check valve Assume that 6 is closed. Next, it is assumed that a mountain of waves has come and the entire apparatus has been lifted to this mountain.
Then, the discharge port 14a at the end of the drain pipe 14 protruding through the outer peripheral surface of the floating body 1 is located near the wave trough on the sea surface 3 as shown in the figure. Therefore, a water level difference occurs between the water surface 7a of the water in the main tank 7 and the sea surface 3 near the wave trough, and the water in the main tank 7 passes through the drain pipe 14 and is provided at the discharge port 14a. The valve 15 is pushed open and discharged outside the device.

At this time, when an unexpected large wave comes and this wave tries to hit the check valve 15, this valve is destroyed because the protection frame 21 and the protection fence 22 are provided in front of it. And damage can be avoided.

In addition, when the entire apparatus shakes greatly in response to these large waves, the water in the main tank 7 undulates or foams, and bubbles and bubbles contained in the water at the time of this abnormal phenomenon are discharged. When they flow into the drain pipe 14, they come into contact with the ceiling 16 of the drain pipe 14 and rise upward through the drain port 14 a, since the drain pipe 14 is inclined upward in the upward shape from the discharge port 14 a. By the action, the bubbles, bubbles and the like are returned into the main tank 7 and simultaneously radiated upward.

Therefore, these bubbles and air bubbles are returned to the main tank 7 at an early stage when they do not reach the discharge port 14a at the end of the drain pipe 14, so that the resistance in the drain pipe 14 is relieved and drainage is reduced. Increasing the speed increases the performance of the device.

Next, FIG. 2 will be described. FIG. 2 is a plan view taken along the line AA in FIG. Since most of the description of this figure has been made in the description of FIG. 1, the description of the overlapping part will be avoided, and only the part of the description that is insufficient will be described.

The floating body 1 has a substantially circular shape, and a main tank 7, a check valve 6, a guide 11, an opening 2a, and the like are arranged substantially concentrically with the center thereof as shown in the figure.
The drain pipe 14 extends radially from the outside of the main tank 7,
A check valve 15 is provided through the side plate of the floating body 1 and near the discharge port 14a. Outside the check valve 15, a protective frame 21, a protective fence 22, and a grid 23 are provided for each of the valves.
Alternatively, a crushing device or the like is provided as shown in FIG.
Is protected and the water discharged from it is crushed.

The drain pipe 14 extending radially from the outside of the main tank 7 is made wider as it extends in the radial direction from the main tank 7, so that the water in the main tank 7 is easily discharged.

As will be described in detail later, a surface water discharge nozzle 31 and the like are also provided near the outlet 14a at the end of the drain pipe 14. At the same time, a surface water intake 23 is provided on both outer sides of the drain pipe 14, and a suction strainer 27, a check valve 26, and the like are connected to the intake. A ring pipe 25 arranged in a ring shape is provided below the drain pipe 14 in the floating body 1, and the surface water intake port 23 is provided.
And the surface water discharge nozzle 31 are connected to the ring pipe 25 using pipes or the like.

Next, the operation will be described. On a substantially circular floating body 1,
Regardless of which direction the wave enters, the conditions are almost the same, but the wave arrives and the wave passes through the protection fence 22 and the check valve 1
Suppose you hit 5. At this time, it is sufficient if the check valve 15 operates normally and the external water does not flow into the drain pipe 14. However, if the check valve 15 does not operate normally due to the fluctuation of the device or the like. It is assumed that water outside the apparatus flows backward from the outlet 14a at the end of the drain pipe 14. At this time, since the width of the drain pipe 14 is reduced (widened when viewed from the main tank 7 in the radial direction) as the width of the drain pipe 14 advances toward the main tank 7 from the discharge port 14a, Cannot flow into the main tank 7 unless the flow velocity is increased as it goes deeper into the drain pipe 14 or the water surface is raised considerably. Therefore, in any case, the backflow water has a large resistance for reducing the pipe line, and it is difficult for the backflow water to flow back therethrough.

The explanation is before and after, but as another phenomenon,
If the width is made wider in the radial direction than the main tank 7, the level of the water outside the outlet 14a provided at the end of the drain pipe 14 decreases due to the progress of the wave, the check valve 15 opens, and this outlet 14
Assuming that the water is drained from a, the water level can be rapidly lowered in this area due to the wide drainage channel.
This phenomenon is caused by the difference between the water level 7a in the main tank 7 and the water level near the outlet 14a where the water level is rapidly lowered.
The flow rate of the drainage in the tank 4 is increased, and the water in the main tank 7 is drained at once.

The two functions are effectively utilized to improve the efficiency of pumping the bottom water for the purpose of water intake. The detailed description of the surface water intake 23, the ring pipe 25, and the surface water discharge nozzle 31 will be described later.

The following description will be made with reference to FIGS. FIG. 3 is a schematic diagram showing a state when the device of the present invention comes to a wave trough, and FIG. 4 is a schematic diagram showing a state when the device of the present invention comes to a wave peak. Since the description of the configuration of the apparatus itself shown in this figure is almost the same as that of FIG. 1, the description will not be repeated. 3 and 4
As is clear from the figure, in the water outside the floating body 1 and the water in the pumping pipe 2 and the main tank 7, the former means that the motion of water particles is large due to the waves, and the latter means that the water is small. I do.

Next, the operation will be described. First, as shown in FIG. 3, the wave descends and the device becomes a valley of the wave, and the average sea level 3
When the main tank 7 is moved slightly below, the inside of the main tank 7 becomes in a negative pressure state and the pumping check valve 6 opens, and the seawater at the lower part of the main tank 7 passes through the pumping check valve 6 into the pumping pipe 2. Moves upward, and flows into the main tank 7. When the apparatus reaches the lowest part of the wave trough, the water pressure in the main tank 7 and the water pressure in the lower suction pipe 2 become equal, and the flow of seawater in the suction pipe 2 stops. The water surface in the main tank 7 is 7a.

Next, as shown in FIG. 4, when the wave gradually rises and the apparatus starts to rise, the water pressure in the main tank 7 is increased.
When the water pressure becomes higher than the water pressure in the lower pumping pipe 2, the pumping check valve 6 closes, and the seawater in the main tank 7 is lifted above the sea surface as the waves rise. When the water reaches the top of the wave over the average sea level 34, the drain 1
4 and its discharge port 14a begin to be exposed above the sea surface 3, and at the same time, the main tank 7 above the check valve 6 for pumping.
The water surface 7a of the main tank 7 depends on the head pressure of the seawater inside.
Is higher than the discharge port 14a, the check valve 15 for drainage opens, and the seawater pumped into the main tank 7 passes through the drain pipe 14 and is discharged from the discharge port 14a to above the sea surface 3. Will be.

At this time, the discharge port 14a is exposed above the sea surface 3, and the drainage is sprinkled while being aerated so as to be exposed to the air. Therefore, by exposing cold water such as deep water (bottom water) to air above the sea surface, not only does the temperature of the atmosphere fall, but also the concentration of carbon dioxide in the atmosphere decreases. In other words, cold water in the deep sea has a great effect of absorbing CO _{2 and the} like in the atmosphere, and phytoplankton contained in this water is mixed with surface water to add photosynthesis, etc. Therefore, the absorption of CO ₂ increases, and the concentration of carbon dioxide (CO ₂ ) in the atmosphere can be further reduced, which is very useful for preventing global warming.

The stagnant water stagnating in the sea bottom of a closed water area such as a harbor is exposed to the oxygen in the atmosphere by exposing the bottom water pumped in the anoxic state to the air in the atmosphere on the sea surface. Can be dissolved, and the activation of seawater is effectively achieved.

When the apparatus descends again due to the movement of the waves, the inside of the main tank 7 becomes in a negative pressure state, but the drain check valve 1 provided near the drain at the end of the discharge pipe 14 is provided.
With the closure of 5, the seawater on the sea surface side does not flow back into the main tank 7 except for an abnormal case such as a large wave. In addition, since the check valve 15 for drainage is provided near the drainage port 14a of the drainage pipe 14 and has a shape that is wider in the radial direction than the center of the apparatus, the seawater is drained in the drainage pipe 14. The reciprocating flow does not adversely affect the opening / closing operation of the check valve 15 for drainage or the pumping efficiency.

Thereafter, by repeating the same vertical movement, the seawater on the seafloor side is well pumped while being aerated on the sea surface, and the bottom water and the surface water are mixed.

Next, FIGS. 5 and 6 will be described. FIG. 5 is an enlarged plan view of a drain pipe and a surface water intake of the present invention. FIG. 6 is a vertical sectional view taken along the line BB of FIG. 5 and 6 will be described below.

In FIG. 5, a drain pipe 14 extending from the main tank 7 and a discharge port 14a thereof have a relationship as shown in the figure. Surface water intakes 23 are provided on the sides of the floating body 1 on both sides of the drainage pipes 14, from which the intake pipes 24 extend toward the center of the device, and each of the intake pipes is located below the drainage pipe 14. The inside of the floating body 1 is connected to a ring tube 25 that makes a round circuit inside. The intake pipe 24 penetrates the wall of the surface water intake 23, and a check valve 26, a suction strainer 27, a grid 28, and the like are also connected to the inside of the intake as shown in FIG. It is assumed that surface water can flow into the ring pipe 25 through these constituent devices.

FIG. 6 is a longitudinal sectional view taken along the line BB of FIG. 5, so that the ring pipe 25 is arranged below the drain pipe 14 as shown. As described with reference to FIG. 5, the intake pipe 24 connected above the ring pipe 25 and extending toward the outside of the floating body 1 penetrates the wall of the surface water intake port 23, and a check valve is provided at the end. 26, Suction strainer 2
7, the configuration of the grating 28 and the like also have the relationship shown in the figure. The water intake pipe 24 has a rising shape as approaching the outside of the floating body 1, and a vent hole 29 is provided inside the surface water intake 23,
A check valve 30 is attached to this.

Accordingly, when bubbles or bubbles are mixed into the ring pipe 25 or the water intake pipe 24 due to a large wave or the like, it can be immediately removed from the vent hole 29 and the check valve 30.

The operation of FIGS. 5 and 6 will be described below. A wave arrives at any one of a large number of drain pipes 14 extending radially from the main tank 7, and the height relationship between the water surface 3, the drain pipe 14 and the surface water intake 23 is shown in FIG.
It is assumed that the state is as shown in FIG. Since the surface water intake 23 is below the water surface 3, water pressure is applied to the inside of the surface water intake 23 due to a difference in water level. Due to this water pressure, water outside the floating body 1 pushes open the suction strainer 27 and the check valve 26, passes through the water intake pipe 24, and enters the ring pipe 25.

At this time, the vent hole 29 and the check valve 30 provided in the intake pipe 24 are connected to the water pressure in the intake port 23 and the intake pipe 24.
The internal water pressure is equalized and almost equal to each other, so that there is almost no operation. However, only when bubbles or bubbles are mixed in the water intake pipe 24, it can be extracted therefrom. Therefore, as long as water in the ring tube 25 is not actually extracted somewhere, the water is filled therein,
The water at the peak of the wave outside the floating body 1 cannot flow into the ring pipe 25 through the water intake pipe 24 only by applying water pressure to these pipes.

The following description will be made with reference to FIGS. FIG.
FIG. 8 is a plan view in which a surface water discharge nozzle is provided in the bottom water discharge conduit of the drain pipe 14 of the present invention, and FIG. 8 is a longitudinal sectional view taken along the line CC of FIG. The configuration of FIGS. 7 and 8 will be described below.

In FIG. 7, a drain pipe 1 provided in a floating body 1 is shown.
Numeral 4 is provided radially from the main tank 7 and widens as it extends in the radial direction. A surface water discharge nozzle 31 is provided near the drain pipe 14a, and the nozzle 31 and the ring pipe 25 are connected by a discharge pipe 32. Since the nozzle 31 is located in the bottom water discharge line in the drain pipe 14, it is assumed that a measure is taken so that the flow of water does not become too low when the bottom water is discharged.

In FIG. 8, a drain pipe 1 provided in a floating body 1 is shown.
Numeral 4 extends from the main tank 7 in the radial direction, penetrates through the side plate of the floating body 1 and protrudes to the outside of the floating body 1, and has a check valve 15 at its discharge port 14a. Drain pipe 1
The surface water discharge nozzle 31 and the discharge pipe 32 connecting the ring pipe 25 are connected in the shape shown in the figure near the bottom of the nozzle 4 and near the discharge port 14a, and the water surface in the main tank 7 is located at the position 7b. I do. Support 33 for surface water discharge nozzle 31
It is assumed that measures are taken such that the bottom layer water in the drain pipe 14 is not very resistant to the flow of the water when the bottom layer water is discharged.

The operation of FIGS. 7 and 8 will be described below. First,
As described briefly in the description of FIG. 6, when the arrangement of the drain pipe 14 of this device is viewed as a whole (in a plan view), there is a wave peak portion in any direction (direction), and that portion is present. Since the water surface 3 is located slightly higher than the surface water intake 23 and the ring pipe 25 in the floating body 1, the surface water intake 23 and the ring pipe 25 are subjected to a corresponding water pressure.

On the other hand, the drain pipe 14 having the wave peaks
And the drainpipe 14, which is about 90 ° different from the general direction, is often approaching a wave trough. Therefore, FIG.
As described above, the surface water discharge nozzle 31
Is located at a higher position than the ring pipe 25 but the drain pipe 14
6 and the water surface 7b of FIG. 8 or the surface water discharge nozzle 31
In either case, a water head pressure is generated due to a difference in water level at the sea surface.

Therefore, the surface water outside the surface water intake 23 shown in FIG. 6 passes through the suction strainer 27 in the surface water intake 23, pushes the check valve 26 open, passes through the intake pipe 24, and passes through the ring pipe. Enter 25. Subsequently, the water is discharged from the surface water discharge nozzle 3 provided in the drain pipe 14 at the wave trough in a direction different from the drain pipe 14 at the wave crest in plan view.
1 and the ring pipe 25 are connected via a discharge pipe 32, so that the water is discharged from the surface water discharge nozzle 31 in this direction due to the water head pressure.

The surface water discharge water and the bottom water flowing in the drain pipe 14 are mixed in this portion, and the floating body 1 is discharged from the discharge port 14a.
When the water is discharged to the outside of the water, there is no significant difference between the surface water and the discharged water in terms of water temperature and specific gravity. The surface water on the water surface 3 and the bottom water discharged from the apparatus can be mixed widely without sinking to the deep seabed.

Next, the bottom water pumped up from the pumping pipe 2 of the apparatus enters the main tank 7, flows through the drain pipe 14 and is discharged from the discharge port 14a. Due to the rapid flow velocity of the bottom water flowing through the surface water, the surface water discharged from the surface water discharge nozzle 31
Produce a suction effect, increase the water supply effect of surface water,
It further improves the mixing effect of surface water and bottom water.

[0053]

In summary, according to the present invention, the following excellent effects can be obtained.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the operation of the present invention using the energy of wave, which is a clean natural energy, in today's world where global warming, destruction of the global environment, depletion of energy resources, etc. have become major problems.

[0002]

2. Description of the Related Art Generally, the cultivation of seafood and seaweeds,
In biomass, biotechnology, marine ranch, measures to prevent global warming, and purification of seawater, surface seawater is created by floating deep water (bottom water) in the bottom layer of the ocean, etc., on the sea surface and mixing it with surface water. Temperature drop, phytoplankton contained in cold water and deep water
O ₂ ) is absorbed to lower the concentration of carbon dioxide in the atmosphere, fertilization of the sea area, increase of marine resources, etc.
It is generally widely known that low-oxygen water in the bottom layer is floated on the sea surface, mixed with surface water using ocean currents and waves, and purified by contacting air in the atmosphere. I have.

[0003] For this reason, conventionally, it has been general to use a driving source such as an electric motor or an internal combustion engine to take in this deep water (bottom water).

On the other hand, as a means for pumping seawater or the like utilizing natural energy, a device for drawing water using wave power is a "seawater pumping apparatus" invented by the same inventor as the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view showing an embodiment of the apparatus for pumping seawater or the like using the energy of waves according to the present invention. As shown in FIG. 1, a pumping apparatus 1A for seawater or the like utilizing wave energy (hereinafter referred to as a pumping apparatus) 1A is moored on a sea or in a closed water area such as a harbor using a mooring line such as a chain or a rope. ing.

In the pumping apparatus 1A, a pumping pipe 2 is attached to a substantially central portion of a floating body 1 that floats on the sea surface 3 and moves up and down following waves to penetrate therethrough. It is integrated. The lower end opening 2b extends toward the seabed 4 side. At the upper end of the upper opening 2a of the pumping tube 2, a check valve valve seat 5 is provided so as to warp outside the opening 2a, and a check valve 6 is provided thereon. . A portion above the check valve 6 is defined as a main tank 7, and the water surface of the tank is defined as 7 a, and this tank is integrally connected to the floating body 1. The check valve 6 has a valve plate 8 and a weight 9 and a floating body 10 integrated with each other.
The valve plate 8 does not fall over due to the center of gravity.

A guide 11 is provided outside the valve plate 8, and a stopper 12 is fixed to an upper end of the guide 11 so that the valve plate 8 cannot move upward any more. The guide 11 keeps a certain gap,
Made of rods, steel bars, etc., the bottom water near the seabed 4 is 2b, 2a
, The check valve 6 is opened, and it is possible to enter the main tank 7 through the gap of the guide 11. A flexible flexible hose 13 is provided below the pumping tube 2 so that the lower portion of the pumping tube 2 does not reach the seabed even if the floating body 1 abnormally drops during a large wave. Further, depending on the location conditions in terms of the economy and efficiency of the apparatus, such means can be used from the middle of the pumping pipe.

Drainage pipes 14 are connected to both side walls of the main tank 7 and extend radially from the pipes, and at the same time, penetrate the side plate of the floating body 1. The water in the main tank 7 is
It is assumed that the water can be drained to the outside of the floating body 1 through the tank 4, but the external water cannot flow back into the main tank 7 by the check valve 15.

The ceiling surface 16 of the drain pipe 14 has a rising shape as it goes toward the center of the apparatus.
When the water inside is drained to the outside of the apparatus from the drain pipe 14, the air and water contained in the upper part of the water surface 7a in the main tank and bubbles and bubbles contained in the water are hardly entrained. If the device is shaken during a large wave or the like, bubbles or bubbles contained in the water in the main tank 7 may be removed from the drain pipe 14.
Even if it is entangled in the water, it is lifted while being transmitted by utilizing the slope of the ceiling surface 16 of the drain pipe 14 and is taken out immediately. It can be escaped to.

Below the floating body 1, in the vicinity of the attachment of the pumping tube 2, a mounting bracket 17 for a chain or a mooring line is fixedly connected, and a chain or a mooring line 18 is connected thereto, and the other lower end is clearly shown in the figure. Although not done, it is tied to anchor 19 or the like.
This pumping device is moored by the above-described method, a floating body 1 is placed on the sea surface, and a pumping tube 2 is suspended just below the floating body 1. One point may be moored below the device, depending on the conditions of navigation of the ship in the sea area and currents. Floating body 1
A sign lamp 20 and the like are also provided above the vehicle, and means are provided for preventing navigation of other ships and the like.

The check valve 15 provided at the discharge port 14a at the end of the drain pipe 14 is provided with a protective frame 21, a protective fence 22 and the like as means for preventing operation failure or failure due to unexpected large waves or the like. It is assumed that the check valve 15 is provided to protect the check valve 15. Drainage discharged from the discharge port 14a of the drainage pipe 14 hits a grid 35 or a crushing device or the like, is crushed, and then is discharged near the sea surface.

Next, the operation will be described. Suppose now that the pumping device is in the valley of the wave and the bottom water near the seabed 4 flows into the main tank 7 through the pumping pipe 2 and the check valve 6, and the water surface reaches 7a, and Assume that the flow has stopped and check valve 6 has closed. Next, it is assumed that a mountain of waves has come and the entire apparatus has been lifted to this mountain. Then, the outlet 14a at the end of the drain pipe 14 protruding through the outer peripheral surface of the floating body 1
As shown in the figure, it is near the wave trough on the sea surface 3. Therefore,
A water level difference occurs between the water surface 7a of the water in the main tank 7 and the sea surface 3 near the valley of the wave, and the water in the main tank 7 passes through the drain pipe 14 and the check valve 15 provided at the outlet 14a. And is released outside the device.

At this time, when an unexpected large wave comes and this wave tries to hit the check valve 15, this valve is destroyed because the protection frame 21 and the protection fence 22 are provided in front of it. And damage can be avoided.

In addition, when the entire apparatus shakes greatly in response to these large waves, the water in the main tank 7 undulates or foams, and bubbles and bubbles contained in the water at the time of this abnormal phenomenon are discharged. When they flow into the drain pipe 14, when they come into contact with the ceiling surface 16 of the drain pipe 14, there is a slope that is inclined upward from the discharge port 14 a toward the main tank 7. As a result, the bubbles, bubbles and the like are returned into the main tank 7 and simultaneously scattered upward.

Therefore, these bubbles and air bubbles are returned to the main tank 7 at an early stage when they do not reach the discharge port 14a at the end of the drain pipe 14, so that the resistance in the drain pipe 14 is relieved and drainage is reduced. Increasing the speed increases the performance of the device.

Next, FIG. 2 will be described. FIG. 2 is a plan view taken along the line AA in FIG. Since most of the description of this figure has been made in the description of FIG. 1, the description of the overlapping part will be avoided, and only the part of the description that is insufficient will be described.

The floating body 1 has a substantially circular shape, and a main tank 7, a check valve 6, a guide 11, an opening 2a, and the like are arranged substantially concentrically with the center thereof as shown in the figure.
The drain pipe 14 extends radially from the outside of the main tank 7,
A check valve 15 is provided through the side plate of the floating body 1 and near the discharge port 14a. Outside the check valve 15, a protective frame 21, a protective fence 22, a grid 35
Alternatively, a crushing device or the like is provided as shown in FIG.
Is protected and the water discharged from it is crushed.

The drain pipe 14 extending radially from the outside of the main tank 7 is made wider as it extends radially from the main tank 7 so that water in the main tank 7 can be easily drained.

As will be described in detail later, a surface water discharge nozzle 31 and the like are also provided near the outlet 14a at the end of the drain pipe 14. At the same time, a surface water intake 23 is provided on both outer sides of the drain pipe 14, and a suction strainer 27, a check valve 26, and the like are connected to the intake. A ring pipe 25 arranged in a ring shape is provided below the drain pipe 14 in the floating body 1, and the surface water intake port 23 is provided.
And the surface water discharge nozzle 31 are connected to the ring pipe 25 using pipes or the like.

Next, the operation will be described. On a substantially circular floating body 1,
Regardless of which direction the wave enters, the conditions are almost the same, but the wave enters and the wave passes through the protection fence 22 and the check valve 1
Suppose you hit 5. At this time, it is sufficient if the check valve 15 operates normally and the external water does not flow into the drain pipe 14. However, if the check valve 15 does not operate normally due to the fluctuation of the device or the like. It is assumed that water outside the apparatus flows backward from the outlet 14a at the end of the drain pipe 14. At this time, the width of the drain pipe 14 is reduced (as viewed from the main tank 7 toward the outside of the apparatus, the width is increased) as the width of the drain pipe 14 advances toward the main tank 7 from the outlet 14a. The backflow increases the flow velocity as it goes deeper into the drainpipe 14,
Alternatively, the water cannot flow into the main tank 7 unless the water surface is raised considerably. Therefore, in any case, the backflow water has a large resistance for reducing the pipe line, and it is difficult for the backflow water to flow back therethrough.

The explanation is before and after, but as another phenomenon,
If the shape is expanded radially from the main tank 7, the level of water outside the outlet 14a provided at the end of the drain pipe 14 decreases due to the progress of the wave, the check valve 15 opens, and the outlet 14a
If the water is drained further, the water level can be rapidly lowered in this area because of the wide drainage channel. This phenomenon is caused by the difference between the water level 7a in the main tank 7 and the water level near the discharge port 14a where the water level is rapidly lowered.
The flow rate of the drainage in the tank is increased, and the water in the main tank 7 is drained at once.

The two functions are effectively utilized to improve the efficiency of pumping the bottom water for the purpose of water intake. The detailed description of the surface water intake 23, the ring pipe 25, and the surface water discharge nozzle 31 will be described later.

The following description will be made with reference to FIGS. FIG. 3 is a schematic diagram showing a state when the device of the present invention comes to a wave trough, and FIG. 4 is a schematic diagram showing a state when the device of the present invention comes to a wave peak. Since the description of the configuration of the apparatus itself shown in this figure is almost the same as that of FIG. 1, the description will not be repeated. 3 and 4
As is clear from the figure, in the water outside the floating body 1 and the water in the pumping pipe 2 and the main tank 7, the former means that the motion of water particles is large due to the waves, and the latter means that the water is small. I do.

Next, the operation will be described. First, as shown in FIG. 3, the wave descends and the device becomes a valley of the wave, and the average sea level 3
When the main tank 7 is moved slightly below, the inside of the main tank 7 becomes in a negative pressure state and the pumping check valve 6 opens, and the seawater at the lower part of the main tank 7 passes through the pumping check valve 6 into the pumping pipe 2. Moves upward, and flows into the main tank 7. When the apparatus reaches the lowest part of the wave trough, the water pressure in the main tank 7 and the water pressure in the lower suction pipe 2 become equal, and the flow of seawater in the suction pipe 2 stops. The water surface in the main tank 7 is 7a.

Next, as shown in FIG. 4, when the wave gradually rises and the apparatus starts to rise, the water pressure in the main tank 7 is increased.
When the water pressure becomes higher than the water pressure in the lower pumping pipe 2, the pumping check valve 6 closes, and the seawater in the main tank 7 is lifted above the sea surface as the waves rise. When the water reaches the top of the wave over the average sea level 34, the drain 1
4 and its discharge port 14a begin to be exposed above the sea surface 3, and at the same time, the main tank 7 above the check valve 6 for pumping.
The water surface 7a of the main tank 7 depends on the head pressure of the seawater inside.
Is higher than the discharge port 14a, the check valve 15 for drainage opens, and the seawater pumped into the main tank 7 passes through the drain pipe 14 and is discharged from the discharge port 14a to above the sea surface 3. Will be.

At this time, the discharge port 14a is exposed above the sea surface 3, and the drainage is sprinkled while being aerated so as to be exposed to the air. Therefore, by exposing cold water such as deep water (bottom water) to air above the sea surface, not only does the temperature of the atmosphere fall, but also the concentration of carbon dioxide in the atmosphere decreases. In other words, cold water in the deep sea has a great effect of absorbing CO _{2 and the} like in the atmosphere, and phytoplankton contained in this water is mixed with surface water to add photosynthesis, etc. Therefore, the absorption of CO ₂ increases, and the concentration of carbon dioxide (CO ₂ ) in the atmosphere can be further reduced, which is very useful for preventing global warming.

The stagnant water stagnating in the sea bottom of a closed water area such as a harbor is exposed to the oxygen in the atmosphere by exposing the bottom water pumped in the anoxic state to the air in the atmosphere on the sea surface. Can be dissolved, and the activation of seawater is effectively achieved.

When the apparatus descends again due to the movement of the waves, the inside of the main tank 7 becomes in a negative pressure state, but the drain check valve 1 provided near the drain at the end of the discharge pipe 14 is provided.
With the closure of 5, the seawater on the sea surface side does not flow back into the main tank 7 except for an abnormal case such as a large wave. In addition, since the check valve 15 for drainage is provided near the drainage port 14a of the drainage pipe 14 and is widened radially from the center of the apparatus, seawater reciprocates in the drainage pipe 14. Check valve for draining and draining 1
The opening / closing operation of No. 5 and the pumping efficiency are not adversely affected.

Thereafter, by repeating the same vertical movement, the seawater on the seafloor side is well pumped while being aerated on the sea surface, and the bottom water and the surface water are mixed.

Next, FIGS. 5 and 6 will be described. FIG. 5 is an enlarged plan view of a drain pipe and a surface water intake of the present invention. FIG. 6 is a vertical sectional view taken along the line BB of FIG. 5 and 6 will be described below.

In FIG. 5, a drain pipe 14 extending from the main tank 7 and a discharge port 14a thereof have a relationship as shown in the figure. A surface water intake 23 is provided on both sides of the drainage pipe 14 and on the side surface of the floating body 1, from which a surface water intake pipe 24 extends toward the center of the apparatus, and each of the intake pipes is connected to the drainage pipe 1.
The lower part 4 is connected to a ring pipe 25 which makes a round around the inside of the floating body 1 in a ring shape. The surface water intake pipe 24 penetrates the wall of the surface water intake 23, and a check valve 26, a suction strainer 27, a grid 28, and the like are connected to the inside of the intake as shown in FIG. Can flow into the ring pipe 25 through these constituent devices.

FIG. 6 is a longitudinal sectional view taken along the line BB of FIG. 5, so that the ring pipe 25 is arranged below the drain pipe 14 as shown. As described with reference to FIG. 5, the surface water intake pipe 24 connected above the ring pipe 25 and extending toward the outside of the floating body 1 penetrates the wall of the surface water intake port 23, and is turned upside down. The configurations of the stop valve 26, the suction strainer 27, the grid 28, and the like also have a relationship as shown in the drawing.
The surface water intake pipe 24 has a rising shape as approaching the outside of the floating body 1, and a vent hole 29 is provided inside the surface water intake 23 and a check valve 30 is attached thereto.

Accordingly, when bubbles or bubbles are mixed into the ring pipe 25 or the water intake pipe 24 due to a large wave or the like, it can be immediately removed from the vent hole 29 and the check valve 30.

The operation of FIGS. 5 and 6 will be described below. In FIG. 5, a wave arrives at the outside of any one of a large number of drain pipes 14, which are now radially extended from the main tank 7, and the sea surface 3, the drain pipe 14, and the surface water intake 23 are formed. Assume that the height relationship is as shown in FIG. Therefore, since the surface water intake 23 is below the sea surface 3, water pressure is applied to the inside of the surface water intake 23 due to a difference in water level. Due to this water pressure, water outside the floating body 1 pushes open the suction strainer 27 and the check valve 26, passes through the water intake pipe 24, and tries to enter the ring pipe 25.

At this time, the vent hole 29 and the check valve 30 provided in the intake pipe 24 are connected to the water pressure in the intake port 23 and the intake pipe 24.
The internal water pressure is equalized and almost equal to each other, so that there is almost no operation. However, only when bubbles or bubbles are mixed in the water intake pipe 24, it can be extracted therefrom. Therefore, as long as water in the ring tube 25 is not actually extracted somewhere, the water is filled therein,
The surface water outside the apparatus cannot flow into the ring pipe 25 through the water intake pipe 24 only by applying water pressure to these pipes in the wave peaks outside the floating body 1.

The following description will be made with reference to FIGS. FIG.
FIG. 8 is a plan view in which a surface water discharge nozzle is provided in the bottom water discharge conduit of the drain pipe 14 of the present invention, and FIG. 8 is a longitudinal sectional view taken along the line CC of FIG. The configuration of FIGS. 7 and 8 will be described below.

In FIG. 7, a drain pipe 1 provided in a floating body 1 is shown.
Numeral 4 is provided radially from the main tank 7 and is widened as it extends radially. The drain pipe 1
A surface water discharge nozzle 31 is provided near 4a, and the nozzle 31 and the ring pipe 25 are connected by a discharge pipe 32.
Since the nozzle 31 is located in the bottom water discharge line in the drain pipe 14, it is assumed that a measure is taken so that the flow of water does not become too low when the bottom water is discharged.

In FIG. 8, a drain pipe 1 provided in a floating body 1 is shown.
Numeral 4 extends radially from the main tank 7 and penetrates through the side plate of the floating body 1 to protrude to the outside of the floating body 1. At the same time, a check valve 15 is provided at its discharge port 14a. Drainpipe 14
Near the bottom of the surface and near the discharge port 14a, the surface water discharge nozzle 3
1 and the discharge pipe 32 connecting the ring pipe 25 are connected in a shape as shown in the figure, and the water surface in the main tank 7 is assumed to be at a position 7b. Support 33 for surface water discharge nozzle 31
It is assumed that measures are taken such that the bottom layer water in the drain pipe 14 is not very resistant to the flow of the water when the bottom layer water is discharged.

The operation of FIGS. 7 and 8 will be described below. First,
As described briefly in the description of FIG. 6, when the arrangement of the drain pipe 14 of this device is viewed as a whole (in a plan view), there is a wave peak portion in any direction (direction), and that portion is present. Since the water surface 3 is located slightly higher than the surface water intake 23 and the ring pipe 25 in the floating body 1, the surface water intake 23 and the ring pipe 25 are subjected to a corresponding water pressure.

On the other hand, the drain pipe 14 having the wave peaks
Although it cannot be said unconditionally, the drain pipes 14 having directions different from each other by about 90 ° generally generally reach the valleys of the waves. Therefore, as described in FIG. 8,
Although the surface water discharge nozzle 31 is located at a position higher than the ring pipe 25 but substantially at the bottom of the drain pipe 14, the water surface 3 in FIG. 6 and the water surface 7b in FIG. In this case, a water head pressure is generated due to a difference in water level at the sea surface.

Therefore, the surface water outside the surface water intake 23 shown in FIG. 6 passes through the suction strainer 27 in the surface water intake 23, pushes the check valve 26 open, passes through the intake pipe 24, and passes through the ring pipe. Enter 25. Subsequently, the water is discharged from the surface water discharge nozzle 3 provided in the drain pipe 14 at the wave trough in a direction different from the drain pipe 14 at the wave crest in plan view.
1 and the ring pipe 25 are connected via a discharge pipe 32, and therefore, discharge from the surface water discharge nozzle 31 in this direction due to the water head pressure.

At this time, when the apparatus is viewed in a plan view,
There is a wave peak near any of the outlets 14a, and at the same time, a height due to a combination of various natural conditions such as a wave trough near the outlet 14a in a different direction. By making good use of the difference, the surface water discharge water and the bottom water flowing in the drain pipe 14 are firstly mixed at the outlet 14a in the first stage, and are discharged from the outlet 14a to the outside of the floating body 1. When the water is discharged, the surface water and the discharged water have little difference in surface temperature and specific gravity in terms of water temperature and specific gravity. Therefore, even if the water is discharged to the water surface 3 shown in FIG. The surface water on the sea surface 3 and the bottom water discharged from the device can be mixed widely without sinking.

Next, the bottom water pumped up from the pumping pipe 2 of the apparatus enters the main tank 7, flows through the drain pipe 14 and is discharged from the discharge port 14a. Due to the rapid flow velocity of the bottom water flowing through the surface water, the surface water discharged from the surface water discharge nozzle 31
Produce a suction effect, increase the water supply effect of surface water,
It further improves the mixing effect of surface water and bottom water. Although the description of the present invention has been made with emphasis on the ocean, the same applies to dams, lakes and marshes.

In summary, according to the present invention, the following excellent effects can be obtained.

(1) According to the first aspect of the present invention, not only the deep water (bottom water) is efficiently pumped by utilizing the energy of the wave, but also the bottom water discharged through the drain pipe 14 is discharged. Because of the backflow prevention effect, a further pumping effect can be expected.

(2) According to the second aspect of the present invention, not only the deep water (bottom water) is efficiently pumped by utilizing the energy of the wave, but also the bottom water discharged through the drain pipe 14 is discharged. By immediately extracting bubbles, bubbles and the like contained therein, the drainage effect is significantly increased, and the pumping efficiency of the entire apparatus is increased.

(3) According to the third aspect of the present invention, mixing of the surface water and the bottom water is promoted by efficiently extracting the surface water without requiring any manual operation.

(4) According to the fourth aspect of the present invention, by providing the surface water discharge nozzle in the bottom water discharge pipe of the drain pipe, the first surface primary water in the discharge pipe is provided. And the bottom layer water are mixed, and the temperature difference and the specific gravity difference between the two can be reduced to a certain extent, so that the water can be discharged to the outside of the apparatus.

(5) According to the fifth aspect of the present invention, a ring pipe which goes around the floating body of the apparatus of the present invention is provided, and all the surface water intake pipes and the surface water discharge nozzle are connected to the ring pipe. Thereby, even at the peaks and valleys of the waves that have entered from any direction, the mixing of the surface water intake obtained from the water level difference and the bottom water in the bottom water discharge conduit of the drainage pipe is performed smoothly. .
