Description

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, The present invention relates to a device for absorbing carbon dioxide (CO ₂ ) or the like into cold water or phytoplankton contained in the water, that is, a pumping device for seawater or the like using waves 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 ) etc. to reduce the concentration of carbon dioxide in the atmosphere, fertilize the sea area, increase the amount 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.
1 floats on the sea surface, and a pumping pipe 62 is provided at substantially the center thereof. This pipe is lowered to the water depth for the purpose of water intake.
By moving the valve 2 up and down, the check valves 63, 66 and 67 are pumped to the sea surface by the action of the check valves.

[0005] Since the pumping device 61 for seawater or the like operates using waves, it does not require any energy source that leads to environmental pollution such as petroleum, and once installed, it operates semi-permanently. An excellent pumping device. Therefore, when the deep water (bottom water) containing nutrients such as deep sea is pumped to the surface of the sea using the pumping device 61 of seawater or the like, the deep water (bottom water) is semi-permanently at very low cost. Can be expected to be pumped over the sea surface and continue to be mixed with surface water.

[0006]

However, since the installation depth of the seawater or other pumping device 61 is very deep, as the length of the pumping tube becomes longer, the weight of the pumping tube and the water contained therein are reduced. Resistance such as penetrating force against weight increases,
There are problems such as inferior operation, transportation, manufacturing, strength, and mooring method.

When pumping water, the inside of the flexible hose part may be under negative pressure compared to the outside, so the pipe diameter of this flexible hose is in a reduced state, and it is a very inefficient device, so a major problem in terms of performance was there.

Accordingly, an object of the present invention is to solve the above-mentioned problems and to semi-permanently pump deep water (bottom water) with a simple structure, efficiently and without any artificial operation or fossil energy resources.

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 utilizing waves according to the present invention. As shown in FIG. 1, a pumping apparatus 1A for seawater or the like using waves (hereinafter referred to as a pumping apparatus) 1A is provided with a floating body 1 on the sea surface or in a closed water body such as a seaport or the like, and a pumping pipe 2 is provided therefrom. It is moored in a suspended state near the seabed, and furthermore, using mooring lines such as chains, wires and ropes.

The pumping device 1A is mounted on a substantially vertical center of a floating body 1 that floats on the sea surface 3 and moves up and down following a wave so as to penetrate the floating body 1 in a substantially vertical state. Both are integrated. In addition, the lowermost opening 2W of the insertion hoses 2b and 2c inserted into the fixed pipe 2a of the pumping pipe and suspended therefrom and the flexible hose 2F of the pumping pipe connected to the pipes faces the seabed 4 side. Has been extended. And the upper end opening 2V of the pumping tube 2
A check valve valve seat 5 is provided at an upper end of the check valve so as to warp outside the opening 2V, and a check valve 6 is provided thereon.

A hole is formed in the middle of the check valve 6, and a check valve 6a is provided so as to cover the hole. Also, depending on the design of the device, holes may be formed in the same manner in the order of 6b, 6c, and the like, and the holes may be stacked in multiple stages. 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.

A guide 8 is provided outside the check valve 6, and a stopper 9 is fixed to an upper end of the guide 8 so that the check valve 6 cannot move upward any more. The guide 8 keeps a certain gap,
The bottom water near the seabed 4 passes through 2W and 2V, and the check valve 6 is opened.
You can enter. The flow of the bottom water at this time is set to 10. When the check valve 6 is configured to be stacked in multiple stages as in 6a, 6b, 6c, etc., the check valve 6
A guide 8a and a stopper 9a are provided on the back of the check valve 6a, and a guide 8b and a stopper 9b are provided on the back of the check valve 6a in the same procedure.

The pumping tube 2 is of a suspending type, in which a pumping tube is inserted into a fixed tube 2a of the pumping tube, and a hanging tube 2b is inserted into the tube 2c. It is assumed that it is hung sequentially below the floating body 1. A flexible hose 2F of a flexible pumping tube is provided below the suspending tube 2c for inserting the pumping tube. Even if the floating body 1 is abnormally lowered in a large wave or the like, the suspending of the pumping tube provided below the pumping tube 2 is suspended. The lower part of the pipe 2c does not reach the seabed. Then, depending on conditions such as production, transportation, installation, economy, efficiency and the like of the apparatus, such means can be used from the middle of the pumping pipe depending on conditions.

Drain pipes 11 are connected to both side walls of the main tank 7 and extend radially from the pipes, and at the same time, penetrate through the side plate of the floating body 1. The water in the main tank 7 is
Although it is possible to drain the water to the outside of the floating body 1 through the valve 1, it is assumed that external water cannot flow back into the main tank 7 by the action of the check valve 12.

The ceiling surface 13 of the drain pipe 11 has a rising shape as it goes toward the center of the apparatus,
When the water inside is drained from the drain pipe 11 to the outside of the apparatus, it is configured such that air above 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 11.
Even if it is trapped in the main tank 7, it is lifted up while being transmitted to the drainage pipe 11 using the slope of the ceiling surface 13 of the drain pipe 11, and is immediately returned to the main tank 7. It can be escaped to.

In the pumping tube 2 provided below the floating body 1, the suspension tube 2 for inserting the pumping tube inserted into the fixed tube 2a of the pumping tube.
At the upper end of b, an inner ring tube 15b is provided inside the outward flange portion 14b and near the center thereof, from which an arm 16b extends toward the inside of the insertion suspension tube 2b of the pumping tube and is fixed. I have.

A mounting device 18 for the mooring line 17 is provided above the inner ring tube 15b and the arm 16b, and a screw rod 19 is incorporated in the center of the mooring line 17 as shown in FIG. By turning the handle 20 with a diver or a winch, the screw rod 19 cannot rotate but can move up and down.

The mooring line 17 passes through the inside of the screw rod 19, passes through the return rod 21 provided above the screw rod 19,
Above this, it is assumed that it is securely fastened by the fixing hardware 22. Therefore, the mooring line 17 can freely rotate and slide in the screw rod 19.

The mooring line 17 passes through substantially the center of the pumping tube 2, ie, the fixed tube 2a of the pumping tube, and the insertion and suspension tubes 2b and 2c of the pumping tube.
It is assumed that it passes through F and is connected to the seabed 4 via an anchor 23 provided on the seabed 4 via a chain 24, connecting hardware 25 a, 25 b, and a return 26.

The description of the suspension pipe 2c for inserting the suction pipe in the suction pipe 2 is almost the same as that of 2b except that the outward flange portion 14b is provided at 14c, the inner ring pipe 15b is provided at 15c, and the arm 16b is provided at 15c. Although it has only been replaced with 16c, the attachment device 18 for the mooring line 17 is located in the insertion / suspension tube 2b of the suction tube, but is not in the insertion / suspension tube 2c of the suction tube but only penetrates the mooring line 17. .

A detailed description of the structure of the flexible hose 2F of the pumping tube, its mounting method, operation, and the like will be described later. The check valve 12 provided at the discharge port 11a at the end of the drain pipe 11 is provided with a protective frame 27, a protective fence 28, 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 12 is protected. Drainage discharged from the discharge port 11a of the drainage pipe 11 hits the grid 29 or a crushing device or the like, is crushed, and then is discharged near the sea surface.

Next, the operation will be described. Now, suppose that the pumping device 1A of the present invention is located in the valley of a wave,
The bottom water in the vicinity is drawn from the lower end opening 2W to the suction pipe 2, namely, the flexible hose 2F of the suction pipe, the suspension pipes 2c and 2b for the suction pipe, the fixed pipe 2a of the suction pipe, and the check valve from the upper end opening 2V. 6 and 6a and the like above are opened and flowed in, the water level reaches 7a, the flow of water is stopped, and the check valve 6 and 6a and the like above it are closed.

Next, it is assumed that a wave peak comes and the entire apparatus is lifted by this peak. Then, the discharge port 11a at the end of the drain pipe 11 protruding through the outer peripheral surface of the floating body 1 is
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 11 and is provided at the discharge port 11a. 12
Press open to be discharged outside the device.

At this time, when an unexpected large wave comes and this wave tries to hit the check valve 12, this valve is destroyed because the protection frame 27 and the protection fence 28 are provided in front of it. And damage can be avoided.

In addition, when the entire apparatus is largely shaken by these large waves, the water in the main tank 7 becomes wavy or bubbling, and bubbles and bubbles contained in the water at the time of this abnormal phenomenon are discharged. When they flow into the inside of the drain pipe 11, when they come into contact with the ceiling surface 13 of the drain pipe 11, there is a slope that is inclined upward from the discharge port 11 a toward the main tank 7. As a result, the bubbles, bubbles, and the like are immediately returned to the main tank 7 and simultaneously radiated upward.

Therefore, these bubbles and air bubbles are immediately returned to the main tank 7 at an early stage when they do not reach the outlet 11a at the end of the drain pipe 11, so that the resistance in the drain pipe 11 is reduced. Increasing the moderating drainage rate increases the performance of the device. Next, even if the pumping device provided on the sea surface causes irregular rotation due to seasonal winds, ocean currents, large waves, etc., the reversing members 21 and 26 provided at the upper and lower ends of the mooring line 17 rotate. By acting, the mooring line 17 is prevented from being broken. However,
A detailed description of the rotating action of the rotating fins 36 provided outside the fixed tube 2a of the pumping tube and outside the bottom plate of the floating body 1 will be described later.

The following description will be made with reference to FIGS. FIG. 2 is a schematic diagram showing a state when the pumping device 1A of the present invention reaches a valley of a wave, and FIG. 3 is a schematic diagram showing a state when the pumping device 1A of the present invention comes to a mountain ridge on the contrary. It is. The detailed configuration of the device itself shown in this figure is substantially the same as that described in the description of FIG. 1, and therefore, description thereof will not be repeated. However, FIGS. 2 and 3
As is clear from this figure, the water in the outside of the floating body 1 and the water in the pumping pipe 2 and the main tank 7 have a large motion of water particles due to waves in the former, and the water in the latter is small. Means

Next, the operation will be described. First, as shown in FIG. 2, when the wave descends and the pumping apparatus 1A of the present invention becomes a valley portion of the wave and moves slightly below the average sea level 30, the inside of the main tank 7 is in a negative pressure state and the pumping operation is performed. The check valve 6 and its upper 6a are opened, and the seawater at the lower part of the main tank 7, that is, the fixed pipe 2a of the pumping pipe constituting the pumping pipe 2,
Seawater of bottom water flowing from the lower end opening 2W into the insertion / suspension pipes 2b and 2c of the pumping pipe and the flexible hose 2F of the pumping pipe (not shown in the figure) is checked by a check valve for pumping. 6 and 6a thereabove are pushed open to move upward in the pumping pipe 2, and the bottom layer water flow 10 flows into the main tank 7. When the apparatus reaches the lowermost part of the wave trough, the water pressure in the main tank 7 and the water pressure in the lower suction pipe 2 are balanced, and the flow of seawater in the suction pipe 2 is stopped.
The water surface in the main tank 7 at this time is defined as 7a.

Next, as shown in FIG. 3, when the wave gradually rises and the pumping apparatus 1A of the present invention starts to rise, the water pressure in the main tank 7 becomes higher than the water pressure in the lower pumping pipe 2 thereunder. At the same time, the non-return valve 6 and its own weight 6a etc. are also added, and the check valve 6 for pumping and 6a etc. on it close,
The seawater in the main tank 7 is lifted above the sea surface together with the present apparatus as the waves rise. Then, when the water level 7a of this water exceeds the average sea level 30 and the present apparatus reaches the top of the wave, the drain pipe 11 and its discharge port 11a are connected to the sea level 3.
Of the seawater in the upper main tank 7, such as the check valve 6 for pumping and 6a thereabove, causes the water surface 7a in the main tank 7 to be higher than the discharge port 11a. Because of this, the check valve 12 for drainage opens, and the seawater pumped into the main tank 7
1 and is discharged above the sea surface 3 from the discharge port 11a.

At this time, the discharge port 11a is exposed above the sea surface 3, and the drainage is sprayed 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 in the atmosphere fall, but also the concentration of carbon dioxide (CO ₂ ) 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 by reducing greenhouse gases and the like.

According to the literature and the like, the carbon dioxide (C) absorbed by sea phytoplankton by photosynthesis
The O ₂ ) content is said to be about the same as that absorbed by land plants. In addition, stagnant water stagnating in the bottom layer of closed water areas such as harbors dissolves more oxygen by exposing the bottom water pumped in anoxic condition to the air in the atmosphere on the sea surface And effective activation of seawater is achieved.

Then, when the apparatus descends again due to the movement of the waves, the inside of the main tank 7 is brought into a negative pressure state, but the drain check valve 12 provided near the discharge port 11a at the end of the drain pipe 11 is operated. By closing, the seawater on the sea surface side rarely flows back into the main tank 7 except for an abnormal case such as a large wave. In addition, the check valve 12 for drainage is provided near the discharge port 11a of the drainage pipe 11, and although not explicitly shown in this figure, the width of the check valve 12 becomes wider as it goes radially outward from the center of the apparatus. Therefore, the seawater does not reciprocate in the drain pipe 11 to adversely affect the opening / closing operation of the check valve 12 for drainage and the pumping efficiency.

By repeating the same up-and-down motion thereafter, the seawater on the seafloor side is pumped satisfactorily and efficiently while being aerated on the sea surface, and the bottom water and the surface water are mixed. Although the efficiency of the apparatus and the amount of pumping vary greatly depending on the wave conditions, etc., generally, the bottom water in the flexible hose 2F often has a somewhat smooth flow due to the inertia of the water. Therefore, the opening and closing of the check valve 6 and 6a thereon does not always operate as described above, and the reverse operation or a phenomenon with a different time limit may occur. It is activated.

Next, FIG. 4 will be described. FIG. 4 is a longitudinal sectional view of the pumping apparatus 1A according to the present invention in a state where the pumping apparatus 1A is assembled in a dock or in a harbor and can be towed. The configuration of this figure will be described below.

Floating body 1 of pumping apparatus 1A of the present invention on sea surface 3
, And a pumping tube 2 is provided below the floating body 1. The pumping pipe 2 is inserted with a pumping pipe fixed pipe 2a, a pumping pipe insertion suspending pipe 2b, 2c, etc., which are sequentially inserted, and are pushed in such a manner that they do not reach the seabed 4 in a state of being superposed.
The flexible hose 2F of the pumping tube is pushed into the insertion / suspension tube 2c of the pumping tube in such a manner as to be compressed, and finally the mooring line 17 is passed through.

At the lower end of the mooring line 17, a rebar 26 and a connection fitting 25a are provided. Even if the suspension pipes 2b, 2c and the flexible hose 2F of the pumping pipe are elongated as shown in FIG. 1, the mooring cable 17 is strongly pulled upward by the crane 31 or the like. It is assumed that the flexible hose 2F can be sequentially compressed and retracted into the insertion suspension tube 2c of the pumping tube as shown in FIG. However, since the insertion and suspension pipes 2b, 2c, etc. of the pumping pipes are substantially large in weight, it is safer to contract them using an auxiliary crane or the like. At this time, naturally, the mooring line 17
Passes vertically through the center of the apparatus, it is assumed that the check valve 6 for pumping and 6a and the like on the pump check valve 6 have been removed.

Since the mooring line 17 is very large depending on the scale of the apparatus, the main tank 7 of the present apparatus is used.
The drum 32 and the like are provided above and the tow is wound around the drum 32. While the drum 32 is rotated by a motor or an internal combustion engine, the mooring cable 1 is also
7 can be taken in and out of the drum 32.

Next, the operation and operation of this figure will be described below.
The pumping device 1A of the present invention may be entirely assembled on land depending on the scale of the device and lowered on the sea surface using a crane or the like, or assembled and towed in a dock. And assembling it into a harbor where the water is relatively deep and calm, and assembling it until it can be towed using a large crane or the like.

The assembled device is towed by a tugboat or the like, is directed to a place for installation, and is installed there.

Next, FIGS. 5 and 6 will be described. FIG. 5 is a plan view of a fixed pipe of the suction pipe and a suspended pipe inserted into the suction pipe, and FIG. 6 is a view taken along the line AA of FIG. It is a longitudinal cross-sectional view which shows the insertion state of the insertion suspension tube 2b, 2c of a pumping tube, and the flexible hose 2F of a pumping tube in detail. The configuration of this figure will be described below.

An insertion suspension tube 2b for the suction tube is provided in the fixed tube 2a of the suction tube, and an insertion suspension tube 2c for the suction tube is provided in the insertion suspension tube 2b for the suction tube. A ring-shaped inward flange 33 is provided inside the lower end of the fixed pipe 2a of the pumping pipe.
a is provided, and an outward flange 14b provided on the upper part of the insertion / suspension tube 2b of the suction tube is superimposed thereon. Here, the fixed tube 2a of the suction tube and the insertion / suspension tube 2b of the suction tube are connected. Shall be. Means such as packing are also provided in the overlapped portion, and the sliding portion of the inside of the fixed tube 2a of the suction tube, the outward flange 14b provided on the insertion hanging tube 2b of the suction tube, and the fixed tube 2a of the suction tube are provided. Inward flange 3 provided on the lower inside
It is assumed that measures such as guide rails are provided for the sliding portion of the suspension tube 2b for insertion of the pumping tube 3a and means for preventing the coating and the heat insulating material from being destroyed.

An outward flange 14b is provided outside the upper end of the suspension pipe 2b, and an inner ring pipe 15b is provided inside and near the center of the suspension pipe 2b. Arms 16b extending radially therefrom are provided. Are fixed to the inner side of these 14b and 15b, but a flange 34b and the like are also provided due to the assembly procedure of the apparatus and the work.

An inward flange 33b is provided inside the lower end of the insertion / suspension tube 2b of the pumping tube, into which the next insertion / suspension tube 2c is inserted. After that, 2c, 14c, 15
The detailed description of c, 16c, 33c, 34c, etc. is as described in 2b, 14b, 15b, 16b, 33b, 34b.
Since the description is almost the same, the description will not be repeated.

Insertion of Pumping Pipe The inner peripheral surface of the inward flange 33c provided inside the lower end of the suspension pipe 2c is damaged by the flexible hose 2F of the pumping pipe because the flexible hose 2F of the pumping pipe enters and exits. Means such as rounding and attaching a flexible material such as a pier material shall be provided as no means.

Insertion of pumping tube Inside the hanging tube 2c, an outward flange 1 for hanging a flexible hose 2F of the pumping tube.
4d is provided, and this flange can be overlapped with the inward flange 33c provided at the lower end of the above-mentioned pumping tube insertion suspension tube 2c. An inner ring tube 15d and a suspension neck 37 are provided at a substantially central portion inside the suspension outward flange 14d, from which an arm 16d extends radially and is fixed to the inner peripheral surface of the outward flange 14d. Have been.

The detailed description of the flexible hose 2F of the pumping tube will be described later and will not be repeated in this drawing. However, as will be described in detail later, the flexible hoses 2F of the pumping pipes are stacked in multiple stages, and a mooring line is passed from above the apparatus to below the ring body provided on the lower side of the lowermost stage. Down,
Attach the return bracket 26 and the connection fitting 25a, and
Is strongly pulled upward so that the flexible hose 2F of the suction pipe can be contracted into the insertion suspension pipe 2c of the suction pipe.

Means for covering the mooring line 17 with a coating, a rubber hose, or the like to protect the mooring line 17 are provided outside the mooring line 17. Similarly, the inner ring pipes 15b and 15c described above and 41a described later,
It is assumed that the mooring line 17 is provided with a coating and a measure against abrasion at 41b, 41c, etc. because the mooring line 17 comes into contact therewith.

When the apparatus is towed or installed, the fixed pipe 2a of the pumping pipe and the suspension pipe 2b for inserting the pumping pipe are temporarily supported 35a.
Then, the suspension pipes 2b and 2c for inserting the pumping pipes are the temporary supports 35b.
Then, the suspension pipe 2c for inserting the pumping pipe and the flexible hose 2F for the pumping pipe, which are firmly fastened with the temporary support 35c or the like, can be sequentially unraveled according to the installation procedure.

Outside the fixed pipe 2a of the pumping pipe or the floating body 1
On the outer side of the bottom plate, several rotating fins 36 are provided in the same direction with respect to the center line under substantially the same conditions in several places in the circumferential direction, and over substantially the entire vertical direction of the fixed tube 2a of the pumping tube. Therefore, the sea current is not fixed to the fixed pipe 2a of the pumping pipe or the floating body 1
In this case, it is assumed that the action of the fins 36 causes a slight but slight rotation of the entire apparatus in a certain direction, or that a rotational force always acts in that direction. It is assumed that it is difficult to perform reverse rotation at least from the direction of the fins 36.

Next, the operation will be described. As shown in FIG. 6, it is assumed that the devices of the respective parts, which have been compressed into the fixed pipe 2a of the pumping pipe, are sequentially extended and connected to the anchor 23 of the seabed 4 as shown in FIG. The whole apparatus moves up and down due to the wave up and down movement. On the other hand, not from an overall view of the sea area, but from a narrow viewpoint in the vicinity of each of the individual devices of the present invention, the ocean current flows at a substantially constant speed per unit time and in a certain direction. Flows almost in parallel. Therefore, the operation of the rotating fins 36 causes the device as a whole to rotate slightly in a certain direction, albeit little by little, or a rotational force always acts in that direction.

On the other hand, in FIG. 1 described above, since the mooring cable 17 such as a wire and a rope is formed in a rope shape in a certain direction, the mooring line 17 is twisted, that is, twisted up in a rope shape. Even if the device is slightly rotated or its rotation is stopped, if the reverse rotation is difficult, the mooring line 17 is durable because the rope-like twisting is not broken. When rotated in the opposite direction, the mooring line 17 is unraveled, and the durability is lost. That is, the strength of the mooring line 17 is increased by using this function.

Nevertheless, depending on the conditions of the ocean current, the rotation speed and the rotation force of the device may increase, and the mooring line 1 such as a wire or a rope may be used.
When a phenomenon such as twisting 7 occurs, the wire,
The rebars 21, 26 and the like provided on the upper and lower sides of the mooring line 17 such as a rope act to return the mooring line 17, thereby preventing the mooring line 17 such as a wire or a rope from being cut.

The following description will be made with reference to FIGS. FIG.
8 is a plan view of the upper end portion of the flexible hose 2F, and FIG. 8 is a vertical sectional view showing a detailed configuration of the flexible hose 2F of the apparatus of the present invention, which is a view taken along the line BB of FIG. The configuration of this figure will be described below.

The suspension neck 37 of the flexible hose 2F is passed through an inward flange 33c provided inside the lower end of the above-described suspension tube 2c for inserting the pumping tube 2, and an outward flange is provided outside the upper end thereof. 14d is fixed. The inward flange 33c and the outward flange 14d are overlapped as shown in the figure. However, since these two flanges may slide in the rotation direction, a slippery sliding ring 38 also serving as a packing is provided between them. Is also provided.

An inner ring tube 15d is provided inside the outward flange 14d and near the center of the apparatus, from which an arm 16d extends radially.
4d or fixed inside the hanging neck 37. The arm 16d is also provided with an eye plate 39 for attaching a spring described later.

Inside the lower end of the suspension neck 37, an inward flange 37a for attaching the ring body 40A and the flexible hose 2F are also provided. The ring body 40A is connected to the inner ring tube 41a and the outer ring tube 42a by an arm 43a, and both ring tubes are substantially concentric. An outward flange 44a is provided outside the outer ring tube 42a.
a, the inward flange 37a described above, and a flange portion at the upper end of the flexible hose 2Fa to be described later are fixed with through bolts or the like.

The arm 43a of the ring body 40A is also provided with an eye plate 45a for fixing a spring described later. It is assumed that a support portion of a later-described spring casing is passed through the eye plate 39 provided on the arm 16d and the eye plate 45a provided on the arm 43a of the ring body 40A, and is fastened with a fastening nut or the like. .

The flexible hose 2F is divided every time the ring bodies 40A, 40B, 40C and the like are provided therein.
They are numbered 2Fa, 2Fb, 2Fc in order from the top. Below the outward flange 44a of the ring body 40A,
The upper end flange portion of the flexible hose 2Fa is put in a packing shape, and is pressed from below by a pressing flange 46a.
This and the above-mentioned inward flange 37a, outward flange 44a and the like are simultaneously tightened with through bolts or the like.

A ring body 40B is provided at the lower end of the flexible hose 2Fa.
Although it is almost the same as the case of the ring body 40A described above, the description will be repeated just in case. An inner ring tube 41b is provided substantially at the center of the device, from which the arm 43b extends radially and is connected to the outer ring tube 42b. Outer ring tube 4
An outward flange 44b is provided on the outside of 2b, and the lower flange portion of the flexible hose 2Fa is placed in a packing shape on the upper side, and the holding flange 46b is placed thereon.

Outward flange 4 provided on ring body 40B
The lower end of the flexible hose 2Fb is pressed against the lower end of the flexible hose 2Fb in a packing shape, and the lower end of the flexible hose 2Fb is pressed by the holding flange 46b. To state the above in order from the top,
The holding flange 46b, the flange at the lower end of the flexible hose 2Fa, the outward flange 44b, the flange at the upper end of the flexible hose 2Fb, and finally the holding flange 46b are pressed and simultaneously tightened with through bolts or the like.

The ring body 40C and the detailed description below are substantially the same as the description of the ring body 40B, and thus the description thereof will not be repeated. The arm 43b of the ring body 40B is provided with an eye plate 45b for connecting a wire, a rope, a chain, and the like. The eye plate 39 provided on the arm 16d and the ring 4
The support of the casing 47 of the spring is passed through the eye plate 45a provided at
9 and tighten as shown.

In the spring casing 47, the spring 50 and its pulling rod 51 (actually, the spring is compressed by this pulling rod. Is provided as shown in the figure, and a ring 52 for binding a wire, a rope, a chain, or the like is fixed to the lowermost end.

A ring 52 provided at the lowermost end of a pull rod 51 of the spring 50 and an eye plate 45b provided on the ring body 40B are connected to a wire, a rope, a chain or the like 53.
a, and a shackle or a twister may be provided near the knot. When the floating body 1 shown in FIG. 1 of the apparatus of the present invention moves up and down due to waves, this movement propagates through the pumping tube 2, and the outward flange 14d, the ring body 40A and the casing of the spring shown in FIG. 47 and so on.

Eye plate 45 provided on ring body 40B
b and the eye plate 45c provided on the ring body 40C are firmly connected by a wire, a rope, a chain, etc. 53b, so that the ring body 40B and the ring body 40C
Since the wire, the rope, the chain, and the like 53b cannot be separated far more than the length, it is assumed that this action protects the flexible hose 2Fb.

The inner ring tubes 41a, 41b, 41c used for the ring bodies 40A, 40B, 40C, etc., the outer ring tubes 42a, 42b, 42c, the arms 43a, 43
For b, 43c, etc., it is assumed that the ring body itself has buoyancy by filling it with air or the like using a tube material or the like. For example, a flexible hose 2Fb and a ring body 40B,
In addition, the weight of the two parts of the holding flange 46b and the bolts, wires, ropes, chains, and the like 53b corresponding to each node and the buoyancy of these parts are substantially balanced, so that the entire flexible hose 2F floats like a jellyfish to some extent. Be a body. However, it is assumed that the buoyancy is set to such an extent that if it is kept quiet, it will sink slightly.

Next, the operation will be described. First, look at FIG. 1 to see the overall device movement. It is assumed that the floating body 1 of the pumping apparatus 1A of the present invention floating on the sea surface moves up and down more sensitively to waves. As a matter of course, this movement is transmitted to the fixed tube 2a of the pumping tube, the suspension tube 2b, 2c of the pumping tube in order, and transmitted to the outward flange 14d provided above the flexible hose 2F.

FIG. 8 shows that the up-and-down motion of the floating body 1 is almost unchanged.
To the outward flange 14d, the suspension neck 37, the ring body 40A, the spring casing 47, and the like.
On the other hand, the flexible hose 2 </ b> F in the floating state, which is slightly sunk under the apparatus, floats while being guided by the mooring line 17. That is, the flexible hose 2F
In the vicinity of “a”, the upper part responds sensitively to the vertical movement transmitted from the floating body 1, and below the flexible hose 2Fb, floats at a moderate pace slightly sinking and squatting, irrespective of the upward movement.

Accordingly, it is the flexible hose 2Fa that connects completely different movements above and below the flexible hose 2Fa. Therefore, in this portion, a large tensile action and a compressive action are generated by the energy of the wave. Therefore, the spring 50 and the pulling rod 5 of the spring 50 are provided so that the impact force above the spring 50 is not transmitted to the lower part as it is but has flexibility.
1, means such as wires, ropes, chains and the like 53a are provided.

However, the basic position of the pumping water of the apparatus above the flexible hose 2Fa is to follow the up-and-down motion of the floating body 1 due to the waves and to form a pulsating flow.
The flow below the flexible hose 2Fb is a smooth flow that has been smoothed to some extent. The pulsating flow has a large resistance to the inertial force due to the weight of the fluid in each case, whereas the smooth flow has a small resistance. Therefore, in order to operate the device efficiently, the flexible hose 2Fb which moves in a flexible floating state is required.
It is preferable to lengthen the lower part, but it is also necessary to consider the stability of the device during ocean currents and large waves. Therefore, depending on design conditions, the insertion suspension pipe 2 shown in FIG.
It is conceivable that b, 2c, etc. are deleted and the flexible hose 2F is lengthened.

When the current is particularly severe or when there is a large wave, the flexible hose may be stretched to the lowermost end, not only the flexible hose 2Fa, but also to the lowermost end thereof, such as 2Fb and 2Fc. To prevent this, wires, ropes, chains, etc. 53a, 5
The gap between the ring bodies is limited by using 3b, 53c and the like. For example, limiting the gap between the ring bodies 40B and 40C so as not to extend more than a certain extent by the tension of the wire, rope, chain, etc. 53b significantly increases the durability of the apparatus.

Although described in the description of FIGS. 5 and 6, the rotation fins 36 provided outside the fixed tube 2a of the pumping tube or outside the bottom plate of the floating body 1 are provided. The floating body 1, the fixed pipe 2a of the pumping pipe provided below the floating body 1, and the insertion suspension pipes 2b, 2c, etc. make a slight rotation in a certain direction. On the other hand, flexible hose 2F
May not be able to rotate depending on the bending conditions of the mooring cable 17 or the like. At this time, since a countermeasure such as the slide ring 38 provided between the inward flange 33c and the outward flange 14d performed in the description of FIG. 8 is provided, this part prevents the float 1 from being forcedly rotated. Absorb the rotation,
The rotation cannot be transmitted to the flexible hose 2F.
