2. Description of the Related Art Most of the seawater such as deep water and lake water currently in practical use, the pumping, and the water supply equipment are equipped with a prime mover such as a turbine, an electric motor, an internal combustion engine, etc. on the land, and the suction line of the pump is submerged. It is carried out by operating the pump with the aforementioned power. Also, although it is still in the idea stage with a slightly different method, it has already applied for "Seawater transmission system to be installed on the seabed" (Japanese Patent Application No. 6).
2-97462, 63-171026), but the current situation is that there are no countermeasures for lifting, collecting, replacing, etc. of the equipment caused by equipment failure and life in the deep sea.

[0004]

SUMMARY OF THE INVENTION The present invention relates to water intake such as deep sea water, and the suction line system described above has a problem in that as the suction line becomes longer, the limit of the equipment caused by the limit of the degree of vacuum and the sea bottom or the lake bottom are increased. As long as the pipeline to be laid is a suction line, rigid pipes are required, so there are technical and economic limitations to the construction work, as well as the construction period. However, there was a problem in taking water from the bottom of the ocean and deep water.

Next, to describe the problem of the main body of the water intake device,
"Seawater transmission system installed on the seabed" (Japanese Patent Application No. 6)
2-97462, 63-171026), etc.
Since there is no partition wall between the driving pressure water, that is, the hot water discharge port and the cold water intake port, there is a problem of mixing both water. In addition, because it is not possible to sufficiently fix the drive device such as the water turbine and the intake pump, these vibrations, stability, check valve mounting,
There were also problems with the rectification problem of discharged water and the number of years of service. Next, there was a problem in the operation control of the water intake device laid at the bottom of the water, and the recovery and replacement of the water intake device and the water intake hose.

[0006]

In order to solve the above problems, the present invention relates to a drive device for a water turbine or the like, which is provided with pressure water or a pressure working medium from the land, the ocean, the surface of a lake or the like, and which is provided at the bottom of the water by the pressure medium. The water is pumped to the destination by rotating it and operating the water intake pump linked to it. With this method, it is not necessary to use a rigid pipe for the water supply pipe, and it is conceivable to use a soft pipe such as a vinyl hose, a polyethylene hose, a rubber hose, or a cloth hose. That is, the above-mentioned flexible hose can be folded and carried at the time of transportation, and can be extended from the carrier while supplying air to the hose at the site. In addition, this air is extracted when sunk. Next, when replacing the water intake device that has been sunk, maintenance, or the like, the air that has been extracted may be reinjected.

Further, a pressure water hose 4 for sending pressure water for driving an intake pump or a pressure working medium into a water intake hose 5 provided at the bottom of the water, and a flow for this flow through a valve 25
Pressure water hose 2 for valve opening and closing for control by opening and closing
8. Store underwater camera conductors, other control cables and control hoses at the same time, or water intake hose 5
The purpose is achieved by sunk along the outside of the ship and controlling it from land.

Next, also in the water intake device main body, the above-mentioned water intake device is three-dimensionally viewed, and a tank is provided in the substantially central portion thereof, and this tank is designed to function as a partition plate on the upper side and the lower side of the tank. By doing so, it is possible to solve the problem of mixing the driving pressure water, that is, the warm water discharged from the driving device such as the water wheel provided on the upper side with the cold water taken by the water intake pump provided on the lower side. In addition, if a tank that is structurally reinforced is installed between the drive unit of the water turbine and the intake pump and both of the above-mentioned tanks are firmly fixed to this tank, vibrations, failures, and resonances during operation can be solved. Then, this tank is divided into a collective tank and an individual tank in the vertical direction, and the discharge water discharged from the intake pump passes through the individual tank provided at the upper part of the tank, and the check valve is provided at the collective tank provided at the upper part. Just push it in through. At this time, the check valve should be moved away from the intake pump so that it does not directly hit the valve, or it should be moved as far as possible in the circumferential direction in this individual tank at the location after the water flow has been bent. By providing this valve, the discharge water of the intake pump can quietly and stably flow from the turbulent flow, that is, the rectification problem can be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1AB is a conceptual diagram in the case where ocean temperature difference power generation is performed using the “drainage device for deep water, etc.” of the present invention. The configuration of this figure will be described below.

In the configuration shown in this figure, first, a wave power pump 1 which operates by the power of waves is installed near the coast such as a remote island and a cape on a peninsula. The pressure water obtained from this wave pump 1 is sent to an accumulator 3 provided on land via a water supply pipe 2. It is assumed that the pressure water sent to the accumulator 3 is rectified from the pulsating flow to a smooth flow and is distributed as stable pressure water to some extent according to its purpose.

First, from the accumulator 3 of FIG. 1A to FIG.

Next, the shaft of the drive unit such as the water turbine and the shaft of the intake pump are connected to each other so that the intake pump rotates when the drive unit of the water turbine rotates. Therefore, it is assumed that the water intake hose 5 is connected from the water intake device A of the present invention to the ocean temperature difference power generation plant 6 provided on land. However, at this time, depending on the condition of the sea area, it is naturally conceivable to insert the pressure hose 4 into the water intake hose 5 or to separately connect these two hoses.

The pressure water discharged from the accumulator 3 is sent to a pumped-storage power plant 8 and a hot water intake pump 9 via a pipe 7 as a separate circuit. Here, these pressured water shall be discharged to a farm, an ocean ranch, a harbor, etc. after being used as a power source by rotating a water wheel or the like. Further, the cold water sent from the water intake device A of the present invention is sent to the ocean temperature difference power generation plant 6 via the water intake hose 5, and at the same time, the surface seawater (hot water) from the hot water intake pump 9 passes through the pipe 10 to generate the ocean temperature difference power. Sent to plant 6. Both types of water shall be subjected to temperature difference power generation and then discharged to a farm, marine ranch or port. The following description will be given with reference to FIGS.

FIG. 3 is a vertical sectional view showing the structure and mechanism of the water intake device A of the present invention, and FIG. 2 is a plan view taken along the line Z--Z. The configuration of this figure will be described below. First, it is assumed that the pressure water hose 4 and the water intake hose 5 described above are respectively connected to the water intake device A of the present invention via a flange or the like. In the water intake device A, an aggregate 12 is provided on a substrate 11 having a structure such that the installation position can be moved to some extent depending on the hose laying condition and the floor 13 is laid on the aggregate 12. A support column 14 integrated with these components is provided as shown in the figure, and a collecting tank 15 is fixed to the support column 14 at approximately the center thereof. At the upper end of the pillar 14, there is an aggregate that collects them together, a lifting metal fitting 16, and a roof 17 that has a structure that does not hinder the water turbine or the like even if foreign matter such as pebbles falls from the top of this device. It is supposed to be provided as follows. However, this roof is of a size that does not allow falling objects to enter the drive unit such as the water turbine, and holes are made in places to allow the pressure water discharged from the drive unit such as the water turbine to rise easily. That is, the aggregate 1 is attached to the substrate 11 described above.
2, the floor 13, the pillars 14, the collective tank 15, the lifting metal fittings 16, and the roof 17 are integrated into a rigid structure.

Next, as shown in FIG. 2, drive devices 18 (five in this case) of the water intake pump and the like are arranged above the collecting tank 15, and the drive shaft 20 penetrates the collecting tank 15 and the individual tank 22. The intake pump 21 provided at the bottom
It is assumed that they are respectively connected to. Turbine drive device 18
A discharge pipe 19 and the like are also provided on the upper part of the. Further, in accordance with the number of pumps installed in the lower portion of the collecting tank 15, each pump is provided with an individual tank 22, and at the same time, the water intake pump 21 is attached to the lower portion thereof. Therefore, from the structural aspect of this device, it is the most economical and effective in designing and manufacturing the device to use the pedestal for mounting the water intake pump 21 and the individual tank 22 together. Further, a plurality of check valves 23 are arranged inside the individual tank 22 as shown in FIG. The combination of the water wheel drive device 18 for the water intake pump and its drive shaft 20, the water intake pump 21, the individual tank 22, and the check valve 23 will be described in detail later.

Next, the pressure water hose 4 is provided inside the water intake hose 5 and the collecting tank 15 provided in the water intake device A.
And the intake hose 5, and also a drive unit 1 for the intake turbine such as a water turbine.
8 and the pressure water hose 4 are connected via a pipe 24 and a valve 25, respectively. And at the end of the pipe 24 is a pipe 24
′ And a valve 25 ′ are provided, and foreign matter such as shells, seaweeds, pebbles and iron pieces contained in the pressure water hose 4 and the pipe 24 can be removed by opening the valve 25 ′. The collection tank 15 has a water intake hose 5 and a pipe 2 through which water in the tank can flow in and out.
6, and the valve 27 are provided as shown.
Next, a valve opening / closing pressure hose 28 is connected to each of the valves 25 (five pumps in this case, since there are five pumps), 25 'and 27, and at the same time, the hose is connected to the above-mentioned one. It is assumed that each valve is connected to a valve opening / closing switching device provided on land through the inside of the water intake hose 5. The valves 25, 25'27 are preferably opened / closed by a ball valve by a cylinder opening / closing device, but a butterfly valve or other similar type may be used in view of the size and budget of the device. Next, FIG. 4 will be described.

FIG. 4 is a diagram showing in detail the combination of the intake pump 21 and the drive device 18 for the water turbine and the like. The configuration of this figure will be described below. First, it is assumed that a drive device 18 such as a water wheel of an intake pump is provided on the upper part of the collecting tank 15 and both of them are fixed by bolts or the like. Also a collection tank 15
Shall have a structure that can sufficiently withstand the strength due to the pressure difference between the external seawater and the internal seawater, and the vibration due to pump operation. Next, it is assumed that the individual tank 22 is provided in the lower portion of the collecting tank 15, the water intake pump 21 is provided in the lower portion thereof, and the strainer 29 is provided in the lower portion thereof. This intake pump 21 is an individual tank 2
2, and the strainer 29 is firmly fixed to the water intake pump 21 by bolts or the like. It is assumed that the rotary shaft of the drive unit 18 such as a water turbine and the rotary shaft of the water intake pump are connected by a shaft 20 and at the same time the shaft penetrates the collecting tank 15 and the individual tank 22 as shown in the drawing. In addition, a bearing 30 and the like are also provided in the hole forming portion of this tank. With such a structure, the water intake pump 21 and the drive device 18 such as the water turbine are integrated, and a very stable operation can be performed. Further, if both blades are designed in such a direction as to cancel the thrust action of the shaft generated when the drive device 18 such as the water turbine rotates and the thrust action generated when the intake pump 21 rotates, wear and damage of each part of the device will be prevented. It becomes a durable device.

Next, a plurality of check valves 23 are provided at the lower surface of the collecting tank 15, in other words, on the upper portion of the individual tank 22 as shown in the figure, and the water sent from the water intake pump 21 is delivered to the individual tank 21. It is assumed that the liquid has entered and has been sent to the collecting tank 15 via the check valve 23. At this time, the check valve 23 is of a type that is hung on the lower surface of the collecting tank 15, so that the water intake device (A) is assembled, transported, and lifted.
It is very stable even during installation and operation on sloping ground, etc., and this valve has a structure that is not easily destroyed. Further, it is assumed that the plurality of check valves 23 are arranged at substantially the same distance as far as possible from the rotary shaft 20. Next, the operation of FIGS. 2, 3 and 4 will be described below.

The pressure water sent from the wave pump is once pushed into an accumulator provided on land, and after being rectified there, it is sent to a water intake device A provided at the bottom of the water via a pressure water hose 4. A track device 18 such as a water turbine for driving the water intake pump 21 is naturally provided inside the water intake device A. Therefore, the pressure water sent from the pressure water hose 4 is discharged from the discharge pipe 19 attached to the upper part of the drive device 18 by rotating the drive device 18 such as a water turbine. At this time, the pressure water sent from the land has a high water temperature, and the cold water at the bottom of the water has a low water temperature, so the hot water rises upward.

The rotational force of the drive unit 18 such as the water turbine is transmitted to the water intake pump 21 via the shaft 20. By operating this pump, the water for the purpose of water intake is sucked into this pump via the strainer 29. Then, this water passes through the individual tank 22 from the water intake pump 21, and is sent to the collecting tank 15 via the check valve 23 provided at substantially the same distance from the rotary shaft 20 therein. At this time, the vortex flow discharged from the intake pump 21 once rectifies the flow in the individual tank 22 to some extent, and then opens the check valve 23. Therefore, since this check valve has a cushioning effect to some extent, it can be opened and closed relatively stably. After that, this water that has entered the collecting tank is sent to the ocean temperature difference power generation device 6 provided on land via the water intake hose 5.

Next, as is apparent from the plan view shown in FIG. 2, the water intake apparatus A includes a plurality of water intake pumps 21,
In this case, 5 units are provided. The reason is that this device is a device installed in the deep sea, and therefore cannot be easily inspected and maintained like a land-based device. Therefore, a plurality of pumps are mounted at the same time, and by operating alternately while switching from land, the life of the entire device, that is, the useful life is increased. Next, the method for the operation by this alternate switching will be described below.

First, it is assumed that the valve 25 'is opened by remotely applying water pressure to the valve opening / closing pressure water hose 28 connected to the valve 25' of the water intake device A submerged in the water bottom. That is, in the pressure water sent from the pressure water hose 4, foreign matters such as shells, seaweed, gravel, pebbles, and iron pieces inside the pressure water hose 4 and the pipes 24, 24 'are discharged from here.
After that, if the pressure of the valve opening / closing pressure water hose 28 that has just been applied is removed, the valve opening / closing piston is pushed back by the action of the spring or the like in this valve 25 ', and this valve is closed. Therefore, the remaining intake pumps 21 to be operated can be sequentially driven by the same method.
That is, it is possible to operate a plurality of these pumps by freely operating them from the land on a daily basis, or to schedule them on a daily basis or on a weekly basis. Becomes Next, the installation of this device and the laying of the hose will be described.

FIG. 5 is a diagram showing a procedure for connecting the water intake hose 5 and the water intake device A at the land portion by using the manufacturing quay and for assembling the device into the skid. FIG. 6 shows the intake hose 5 and the intake device A.
It is explanatory drawing which showed the process of mounting and carrying in the skid on the carrying barge 31. FIG. 7 is an explanatory view showing a process of extending the water intake hose 5 from the transportation barge 31 in the installation sea area of the device. The configuration of this figure will be described below. First of all, this figure puts the transportation barge 31 on the sea surface,
This is stopped by the anchor 32. Also this barge 31
The water intake hose 5 is extended from the hose 33, and an air injection hose 33 is connected to the end of the hose 33.
More air can enter and exit the intake hose 5. Next, this procedural operation will be described below. First intake hose 5
Is extended from the carrying barge 31, and air is injected into the hose from the air injecting hose 33. That is, the hose 5 is extended while inflating the floating bag while floating above the water surface. Therefore, at this time, depending on the conditions of the external force such as wind, ocean current, tidal current, wave force in the sea area, wire the hose 5 from the land to adjust its length or provide a construction anchor or the like. It is natural to work. The following description will be given with reference to FIG.

FIG. 8 shows a water intake hose 5 extending above the water surface.
It is also an explanatory view showing a process of submerging the water intake device A in water. The configuration and operation of this figure will be described below. That is, as is apparent from this figure, the water intake device A connected to the water intake hose 5 floating above the sea surface is the crane carrier 34.
For example, it is lifted above the sea surface, the carrying barge 31 is pulled out, and then it is lowered into the water. At this time, on the sea surface, the anchor 35 is sequentially connected to the intake hose 5 from the intake device A side. At the same time, the air previously injected is extracted from the air injection hose 33 attached to the end of the water intake hose 5. That is, the buoyancy of the water intake hose 5 is reduced and the hose is sunk. At this time, the hose 5 while adjusting the wire etc. provided from the land mentioned above.
To land. Depending on the conditions of the sea area, the work float 36, etc. may also be installed while being installed. The following description will be given with reference to FIG.

FIG. 9 is an explanatory view when the water intake hose 5 and the water intake device A are installed on the seabed to be installed. That is, at this time, it is preferable that the water intake device A is installed in a stable position on a horizontal place as much as possible. If installed, on a sloping ground or an unstable place, look at the underwater camera etc. Replacing work must be done before the wire is removed. The following description will be given with reference to FIG.

FIG. 10 is an explanatory view for explaining the means for raising the water intake hose 5 and the water intake device A of the once-sunk ocean temperature difference power generator to the sea surface. Since this configuration is as described above, only its operation will be described. However, since the water intake device A is generally located in the deep sea before that, it seems impossible to hang the hook of the crane carrier 34 etc. once removed from it. Therefore, the air injecting hose 33 described above is used to send air again to the water intake hose 5 to lift the water intake device A onto or near the water surface. However, at this time, as described in the explanation of the configuration of FIG. 3, the intake device A is supposed to be provided with the pipe 26 through which the water in the intake hose 5 and the water in the collecting tank 15 can enter and exit, and the valve 27. Air is injected into the air injecting hose 33 while opening and draining water in the water intake hose 5 from here. The following description will be given with reference to FIG.

As described with reference to FIG. 10, FIG. 11 introduces air into the water intake hose 5 and lifts the water intake device A near the water surface.
It is explanatory drawing which showed the process of hanging the wire etc. which were unloaded from the crane barge 34 using this to a diver. The structure and operation of this figure are substantially the same as those described above, and therefore will not be repeated. The following description will be made with reference to FIG.

FIG. 12 is an explanatory view showing a process in which the lifted water intake device A is placed on the above-described transportation barge 31 or a work pontoon and the water intake device A is replaced or maintained here. The configuration and operation of this figure are not so different from those described above and are general explanations, and therefore will not be repeated.

[0028]

As described above, the "intake device for deep water, etc." of the present invention has a problem of depletion of fossil energy resources such as petroleum and coal in today's ocean temperature difference power generation, concentration difference power generation. By disseminating such information, it is possible to contribute greatly to the development of new energy and energy saving. Next, also in the fisheries industry, it is very meaningful for humanity to perpetuate that deep-water is pumped up to increase aquatic resources by cultivating animal plankton from phytoplankton. Also, from the environmental point of view, by using the relatively simple means of the present invention, the seawater in the bottom layer, which is highly polluted and is highly oxygenated, is pumped to the land, where it is purified and then discharged into the sea, and the pollution is extremely closed. Circulating the upper and lower seawater in the water area is very important for the future global environment, water purification, and securing water resources, and will also make a great contribution to this field.

Also in the details of the water intake device A, a collecting tank 15 is provided in the substantially central part of this device, and a drive device such as a water turbine is placed on the upper part thereof, and discharged water having a relatively high water temperature discharged from this is directed upward. At the same time as it is discharged toward the bottom, in the lower part of the collecting tank 15, in order to take in cold water that should not be mixed with a certain amount of hot water from the water pump 21, this tank serves as a partition plate between the two, so that hot water and cold water are Mixing is reduced and the effect is great. Next, since this equipment is installed in the deep sea, there is no maintenance or inspection at that location.Therefore, a collective tank is placed at approximately the center of the equipment and an individual tank is installed under this tank. Fixing the drive unit such as the water turbine and the intake pump to the top and bottom is very stable because there are few failures against vibrations and resonance phenomena due to the operation of the pump, and other external forces. You can drive very quietly. In addition, since the rotating shaft of this device rotates almost vertically, there is little wear of the bearings, etc., and the force in the thrust direction is in the direction in which the driving device for the water turbine, that is, the water turbine, etc. and the intake pump are offset, so there is no failure Few.

Even in the used equipment submerged in the deep sea, it is impossible to recover the water taken by the conventional steel pipe or the like, but if it is the method of the present invention, it is recovered, replaced, or re-installed. However, because the water intake hose is relatively easy to manufacture and all of the water intake hoses are manufactured onshore, the cost of laying the water intake device and water intake hose is significantly lower than that of steel pipes. As a result, the cost of power generation decreases and its contribution to humankind is great.
