Research has been done on operating a low-speed turbine device to obtain electric power, and has succeeded in its practical application. However,
Huge dams have been constructed in various places, and the amount of water stored in the huge dams is so large that the amount of water flowing down the river is extremely small. And, in the river below the huge dam, the places suitable for installing the low-speed water turbine device, which requires running water of a large amount of river, have been extremely limited, and at present, the place suitable for the installation However, the reality is that there are no rivers at all. In particular, recently, the number of construction of adjustment dams whose main purpose is not to generate electricity is increasing, and there are places suitable for installing low-speed turbines.
Furthermore, it is becoming smaller. And, although the characteristics are slightly different from those of large-flow rivers, similar conditions exist in ocean currents occurring in the ocean. However, even under similar conditions, it is possible to operate the low-velocity turbine device by utilizing the energy of the ocean currents such as the Kuroshio in the ocean. Whether it should be installed or not, even if it is fixed at that place, the current of the ocean current will always move, so if you do not track the flow of the strong ocean current, the energy due to the movement of a large amount of seawater accompanying the movement of a large amount of seawater will be appropriate. It is extremely difficult to make good use of. Therefore, considering the use of ocean currents such as the Kuroshio, there is energy due to the movement of a large amount of seawater, so even if it is possible to exchange energy, the exchange of energy that should be possible is actually , It is not easy, and there is a large amount of seawater movement in the straits and waterworks, or at the intake weir, etc., using the energy that a large amount of running water has, despite the low head,
Even if it can be expected that the low-speed water turbine device can be operated by appropriately utilizing the energy, in reality, the energy cannot be easily used. In particular, in recent years, extremely excellent corrosion-resistant metal materials have been supplied, and not only do they not impair the natural landscape, but rather artificially improve the existing natural environment and Responsible with responsible technology to improve the natural environment and ensure the durability of the low-velocity turbine even after installation of the low-velocity turbine, and in addition,
It is required to be manufactured at low cost. In addition, there is a demand for virtually no maintenance costs. However, the results of that research are not necessarily as good as expected. Therefore, it is now time to move from the research stage to the practical stage. Therefore, it is necessary and urgent to pay attention to the energy of a large amount of seawater in the ocean and utilize the energy. Certainly, until now, it has been
Relying solely on thermal and nuclear power has required large capital costs. In particular, even if the construction costs of thermal power generation and nuclear power generation are cheaper than the construction of a new hydroelectric power plant, today, when public opinion that refuses environmental destruction is dominant, hydropower plants that require a large amount of equipment costs. It is necessary to think about the new establishment. However, in reality, due to the slowdown of the cement manufacturing business, there is a limit to constructing a dam in the deep mountain valley. On the other hand, the possibilities of the ocean are endless and there is no fear of pollution. Accompanying the inflow and outflow of seawater due to the ebb and flow of fresh water such as Lake Shinji and Lake Hamana and the extremely high tide of Ariake Sea, where straits, waterworks and seawater can flow in and out, including the Kuroshio flowing nearby. The use of energy is a topic of the day and there may be research to address it. Japan surrounded by sea on all four sides,
It can be said that it is an opportunity to tackle and research such issues. Considering that even in the Pacific Ocean, when the Kuroshio approaches Japan, the flow velocity grows to the maximum, it is necessary to move from the mere research stage to the practical stage. And an invention by an individual
Even if it is the basis, the technical content is a matter of strong public interest. Therefore, research on the use of energy associated with the movement of seawater should now be in full swing. The use of water energy in rivers is also an important issue of today. For example, even if it is expected that the efficiency of the turbine of the low-velocity turbine will be improved by increasing the size, in reality, the number of installation locations in rivers will be very small, and even in large rivers in Japan where there are relatively many. , Not only the amount of water flowing down is small, but also the flow path that flows down is not fixed, every time of heavy rain,
The flow path that flows down has changed, giving priority to the construction of water discharge channels to prepare for heavy rains and the construction of water blocking weirs to prevent tides during high tides and high tides. The maintenance of rivers to prepare for the disaster has always been postponed, and it has been considered difficult to actually use low-speed turbines in Japanese rivers, if that is not the only reason. At present, it is difficult to install a low-velocity water turbine device in a river.

させることを本発明の第六の目的とする。Therefore, it is required to use the energy of not only rivers but also ocean currents and to appropriately utilize the energy to operate the low-velocity turbine device. When a low-velocity turbine device is installed, the water flowing in at that position is closer to the central axis portion of the low-velocity turbine device than the water flowing into the part farther away.
Its momentum becomes large, and as a result, rather than forming the blade portion of the turbine of the low flow turbine device entirely,
The blade portion is formed only in the portion where the momentum is large to maintain the efficiency at a high level, and the portion of the supporting shaft of the blade of the turbine of the low flow turbine is made to have a relatively large diameter. The part of the support shaft of the blade of the turbine has a hollow shaft, the part of the hollow shaft serves as the water guide passage, and the inside of the part of the hollow shaft becomes the water guide passage that does not substantially contribute to the turning of the blade part of the turbine. It is a first object of the present invention to provide a low-speed water turbine device having a high practicability by allowing water to pass through with as little resistance as possible. Also, it is required to use the energy of ocean currents not only in rivers, but also to properly utilize that energy to operate the low-velocity turbine device. It is not easy to set up and install a low flow turbine device at that position. So, that point is the barrier to commercialization,
It was necessary to eliminate that barrier. Therefore, although not explicitly shown in the drawings, the low-velocity turbine is a position where the blade portion of the turbine of the low-velocity turbine device is removed by several supporting members formed in a radial shape, which is a conventionally used technique. By fixing between the blade shaft part of the turbine of the device and the large-diameter cylindrical structure part that becomes the water guide passage, it is possible to reliably perform the function as a low-velocity turbine device at low cost. A second object of the invention. In addition, the axis connecting the intake and discharge ports of the low-velocity water turbine device in order to maximize the use of the energy of the water current that has the property of changing the direction of the current, such as the Kuroshio Current. It is a third object of the present invention that the direction can always have a proper direction. In addition, in order to make maximum use of the energy of the water current, which has the property of changing the direction of flow of the ocean current, such as the ocean current caused by the vortex of Naruto, the intake and discharge ports of the low-velocity turbine device are A fourth object of the present invention is to make it possible to always have a proper axial direction in the tied axial direction. Also, even when the tide flow between high and low tides reverses, such as in the Kanmon Straits, by reversing the direction of the intake and discharge ports of the low-velocity water turbine device, it is possible to use the direction other than during high and low tides. Virtually continuous,
A fifth object of the present invention is to maximize the use of the energy of the ocean current. Further, in particular, the turbine structure portion and the turbine structure portion are disposed inside, and a large diameter cylindrical structure portion serving as a water guide passage is disposed outside thereof to form a shaft structure portion of the turbine structure portion. , A small-diameter cylindrical structure part penetrating in the front-rear direction is formed inside the shaft part structure part, and the small-diameter cylindrical structure part serves as a water guide passage, and water entering toward the shaft part structure part of the water turbine structure part with a small momentum. By the small-diameter cylindrical structure part that becomes a water guide passage formed in the shaft structure part of the water turbine structure part, the water is effectively guided with little resistance, and the energy of the water flow is used effectively without waste. It is a sixth object of the present invention to operate a water turbine of a low-velocity water turbine device reliably with a relatively simple structure.
