BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water turbine power generator and a water pump.

[0002]

2. Description of the Related Art Water turbines have been around since ancient times, and have been mainly used as small-scale power sources. With the establishment of a stable electricity supply system, water turbines have been left behind and declined from the times.

[0003]

In recent years, global environmental destruction has become a major problem common to humankind. However, securing electricity, which we humans rely on in our daily lives, is also a factor in environmental destruction. It is one. In the case of thermal power generation using coal and oil, air pollution caused by the combustion gas has been pointed out as a cause of deforestation and global warming, and the waste of precious earth resources such as fossils has been concerned from many aspects as a future problem for humankind. I have. In the case of nuclear power generation, in the event of an accident, there is concern about radioactive contamination of the environment, and the actual Chernobyl nuclear power plant accident has left a wide range of disastrous claw marks. In addition, it seems that the cleanest hydroelectric power plant is environmentally clean, and the construction cost of the dam is huge and geographical constraints prevent its construction.

An object of the present invention is to restore a water turbine that has existed since ancient times but has not been effectively used in modern times as a trump card for solving environmental problems in power generation, and thereby to establish a power generation system that is friendly to the global environment. Is what you do.

[0005]

Means for Solving the Problems As described above, the conventional water turbine has only a method of laying a foundation on the ground, such as a mountain valley where a certain amount of water gathers or a river bank, that is, However, conventional water turbines cannot be widely used because they are premised on ground-based installation. On the other hand, the present invention revives the water wheel as a floating water wheel that can be operated by floating on the surface of the river itself where water is abundant.

[0010]

4. The floating water pumped water turbine according to the present invention in
The water wheel (2), the generator (3), etc. are not directly mounted on the surface floating structure (1) such as a ship, but as shown in FIG. A mobile platform (13) provided with a device (12) is installed on a surface floating structure object (1) such as a ship, and a lifting device (12) installed on the surface floating structure object (1) such as a ship is mounted. On a movable platform (13) provided, a turbine (2), a generator (3), a transmission (9), a water pump (10), and the like are mounted.
This is a floating water pumped water turbine. According to a fourth aspect of the present invention, the lifting device (12) of the movable platform (13) stops the rotation by pulling the water wheel (2) completely above the water surface during towing and during maintenance and inspection, so that management is possible. Is to ensure safety. Then, the water wheel (2) in which the slats (15) are underwater and rotating is capable of adjusting the water pressure receiving force by adjusting the depth of the slats (15) from the water surface. Can be obtained. It should be noted that the surface floating structure object (1) such as a ship in the floating power generation pumped water turbine floats on the water surface without any explanation. Careful consideration is necessary for the setting. Therefore, as shown in [FIG. 7], the present invention preferably employs an outer plate structure portion of a water surface floating structure object (1) such as a ship, a water wheel (2), and the like. The supporting part (1) for supporting the mounting load of the mobile platform (13) on which the equipment such as the water wheel (2) is installed is provided separately from the structural part where the equipment is installed.
4) is concentrated on the center of gravity of the water-floating structural object (1) such as a ship in the lateral direction, thereby ensuring the stability of the center of gravity.

[Claim 5] relates to the structure of the water turbine (2) itself in the floating water turbine of the present invention. The blade plate of the conventional water turbine has been attached to a side plate constituting an outer peripheral wheel of the water turbine by being fixed firmly with wedges or the like.
On the other hand, as shown in FIG. 8 and FIG. 9, the blades in the floating water pumped water turbine of the present invention have a blade (1).
A rotating shaft (16) is provided at an arbitrary intermediate point in 5), and as shown in FIG. 10, the provided rotating shaft (16) is used to attach a blade ( 1
5), and a side plate (17) is provided with a blade stopper (18) for stopping the rotation of the shaft-mounted blade (15) at any appropriate position. One of the inside of the blade plate (15) and an arbitrary portion of the water wheel (2) are elastically connected with an elastic material (19) such as rubber or a spring to be connected. With this, the impeller (15) is mounted on the water wheel (2) by axle, but despite being on the axle, the impeller (15) is located in the water and once subjected to water pressure.
Provides a rotational force to the water turbine (2) without any hindrance with the help of the blade plate stopper (18), and furthermore, a shaft bearing located in the air which is not subjected to water pressure in the rotating water wheel (2). Each of the slats (15) is made of an elastic material (19) so that the slats (15) do not rotate freely.
8) It is made stable by being depressurized. According to a fifth aspect of the present invention, the drifting material such as driftwood flows into the river, so that not only the impeller but also the impeller may be damaged by the impact of the collision in the conventional water turbine, but the impeller (15) is mounted on the shaft. The floating water turbine according to the present invention absorbs the impact of the contact by rotating the slats (15) even when it comes into contact with driftwood or the like, thereby preventing the water turbine (2) from being damaged.

A sixth aspect of the present invention is a vane plate (15) provided with a rotating shaft (16) in the floating water pumped water turbine of the present invention.
It is related to the shape of. There are various types of blades in conventional water turbines, such as those with a simple flat surface, and those with a box-like upper surface, such as a rotating blade plate that collects water on the upper surface. Had a shape that did not leave a flat area. On the other hand, the impeller (1)
5) is a special form of being attached on a shaft, so [Fig. 11]
As shown in FIG. 12 and FIG. 13, in the longitudinal direction, a V-shape having a concave upper surface and a convex lower surface is closed, and the tip is closed. )
It is what it was. In the sixth aspect, when the impeller attached to the water wheel is a flat plate, at the time of landing, a slight anti-rotational operation occurs due to the resistance of the water, although momentarily, and this causes a play of rotational force called loss. Therefore, in order to reduce the water resistance at that moment, the shape of the lower surface of the slat (15) is formed into a V-shaped convex shape with a sharp apex most suitable for cutting water. Furthermore, the V-shaped convex shape on the lower surface is also effective in reducing the resistance of the slat (15) from separating when the blade (15) separates from the water surface. In addition, although the surface floating object (1) such as a ship is moored on the water, the water does not always hit the slat (15) from directly in front of the surface, let alone the upper surface has a simple planar shape. In the case of the wing plate, the water pressure is released laterally or diagonally, so there is a loss in receiving the water pressure. However, the wing plate (15) provided with a V-shaped concave groove on the upper surface has The groove that closed off catches without escape. Although not shown in the drawings, if a pinhole is provided at an arbitrary position from the tip of the V-shaped slat (15), the air flows into the closed groove when water is separated. Facilitated, resulting in increased water removal efficiency. in this way,
The convexities on the lower surface and the concaves on the upper surface formed at the same time by the V-shape are the blades (1
In 5), it exerts tremendous efficacy.

[Claim 7] relates to the structure of a water-floating structural body (1) such as a ship in the floating water-powered pumping water turbine of the present invention. As shown in [FIG. 14], all the ships are constructed of components such as steel such as iron, wood, and reinforced plastics, and the internal space (20) of the constructed structure stores luggage and the like. It was a functional space that was needed for loading. On the other hand, the water surface floating structural object (1) such as a ship in the present invention is the internal space (2) of the structure.
0) because there is no use for loading luggage,
5] in the internal space (20) of the structure, any suitable amount of a foaming chemical (2) such as styrofoam.
1), and this is used as a water-floating structural body (1) such as a ship, which is filled with a foaming chemical substance (21) in a floating-type power generation pumped water turbine. The floating body (1) such as a ship according to claim 7 increases the buoyancy with a very light foaming chemical substance (21) filled therein and obtains the volume pressure of the foaming chemical substance (21). Since the strength of the component material with respect to the water pressure of the water-floating structural object (1) can be reduced, manufacturing costs can be reduced.

To describe an example of mounting a water wheel (2) on a water-floating structural object (1) such as a ship, as shown in FIG. 1, FIG. 2, FIG. 4, and FIG. The two sets of water turbines (2) are arranged and set on both symmetrical sides of the surface floating structure object (1), and the generator (3) and the pumping device (10) are also intended. Is set at each of the predetermined positions.

As an extension thereof, as shown in FIG. 16, if physically possible, a plurality of water turbines (2) having a pair of symmetrical two units may be mounted.

Further, FIG. 17 shows that the installation positions of the water turbines (2) are alternately arranged in the horizontal direction, so that
This makes it possible to mount more water turbines within a limited range.

[0017] Then, as shown in Fig. 18, a water-floating structure object (1) such as a ship in a floating-type power-generating pump-turbine mounted with a water turbine (2), a generator (3), and a pumping device (10). ), A connector (22) is provided before and after the surface floating structure object (1) such as a plurality of ships provided with the connector (22) is connected to each connector (22) as shown in FIG. 22), and are knitted as a plurality of unions and moored in the river. The intention of knitting with this coupler is to obtain as much electricity as possible, build large numbers of water-floating structures such as ships on a suitable scale without dare to make them huge, and connect them like a train With the aim of knitting and mooring, while getting more electricity,
In addition, when constructing a water-floating structural object such as a ship that is equivalent to a ship of thousands or tens of thousands of tons, which can reduce the size of maintenance measures and evacuation countermeasures in the event of a disaster such as a flood, etc. It is necessary to prepare a suitable quay quay, but if it is large enough to be suspended by a large crane or the like, it can be lifted on land and stored on land to evacuate from disasters such as typhoons.

[0018]

According to the present invention, the water flowing down the river has potential energy at every point in the basin, but the existence of a turbine that changes the flow of water into energy has been forgotten. In modern times, most of the potential energy of the water flowing down of all rivers on the earth is absorbed into the sea without being effectively utilized. On the other hand, the present invention is characterized in that the waterwheel and the generator are floating floating power pumped water turbines floating on the water,
If there is a certain depth and width of the river in the long basin from the upstream to the estuary, it is possible to moor a floating water-powered pumped water turbine of a corresponding scale as much as possible. To put it in extreme terms, tens of thousands of Floating Water Pumped Mills moored across the river basin,
By rotating the water turbine without wasting 365 days a year, 24 hours a day without wasting the potential energy flowing in meters, it is possible to supply an incalculable amount of electricity. As described above, the floating hydroelectric turbine of the present invention has a large number of water surface floating structures having a size corresponding to a ship of the tens of thousands tons class, including a small one in accordance with river conditions. By constructing them and installing them with water turbines and generators and operating them in rivers around the world, the reliance on thermal power and nuclear power, which had to be relied on so far, can be greatly reduced, and emission The greatest effect of the present invention is to prevent air pollution by gas and to save fossil resources in the future, and to prevent the danger of radioactive contamination of fear. That means you don't need it at all. And furthermore, since the floating water generating pumped water turbine of the present invention is moored on abundant water,
Along with power generation, pumping water from a pumping system to an area or farmland that is chronically short of water due to geographical factors can produce invaluable synergies, such as increased food production, expansion of green spaces, and improved environmental health throughout the region.

Then, during the Industrial Revolution before the invention of the screw as a propulsion device for a ship, a ship equipped with a steam engine as a power source was equipped with a foreign vehicle as a propulsion device. The outer wheel as the propulsion unit of this ship is similar in structure to the water wheel, but the outer wheel without being called the water wheel is
Its intended function is defined as a foreign wheel because it is the exact opposite of a water wheel.In other words, a water wheel is a passive function that is rotated by the energy of flowing water, whereas a water wheel is its own rotation obtained from other power sources. It is an active function to transmit the power of water to water. Thereby, in the present invention, a floating power generation pumped water turbine mounted on a surface floating structure object such as a ship,
This is a radically different definition from a ship of the Industrial Revolution when a foreign vehicle was installed as a propulsion device.

The concept of a ship is defined as a structure capable of moving on the water surface or underwater, and is defined as a means of transportation on which people and goods are placed. It is not a ship because it is not a means of transport as defined by a ship, but it cannot be determined if it is not a ship.
In any case, a waterwheel may be mounted on a structure that is defined as a ship and is equipped with a propulsion device such as a screw, and in addition, floating is one of the important functions, which is mooring on the water surface. Since it does not matter whether a water turbine is mounted on a surface floating structure such as a dock or the like, in the present invention, the structure on which the water turbine is mounted and installed is dared to be a surface floating structure such as a ship. .
