Description

  The present invention relates to a hydrodynamic power generation apparatus that utilizes the energy of a fluid.

  Currently, large-scale power generation facilities such as hydroelectric power generation, thermal power generation, nuclear power generation, geothermal power generation, wind power generation, and solar power generation are installed, and the electric power obtained from these power generation facilities is not large. It is supplied to users using incidental facilities. There are also provided private engine power generators and small hydroelectric power generators that are convenient for carrying when power cannot be received or for some places. Furthermore, in recent years, the spread of private solar power generation devices has been remarkable as their own power.

  Installation of hydroelectric power plants, thermal power plants, nuclear power plants, etc. requires enormous costs for large-scale civil engineering work and construction work as well as construction of incidental facilities. There are problems such as abnormalities in the ecosystem caused by these various constructions, and adverse effects on the natural environment, such as exhausts during operation polluting the atmosphere.

  In view of the above-mentioned phenomenon, the present invention enables installation, movement, and removal of natural clean energy, particularly fluid energy such as water flow and tide flow, which can be converted into clean electrical energy. An object of the present invention is to provide a hydroelectric power generation apparatus that can be easily provided with a necessary scale at a required place without impairing the natural environment.

  In order to achieve the above object, the present invention achieves mechanical energy by rotating a pressure receiving plate that receives the energy of the fluid according to claim 1 and a rotating body integrated with the pressure receiving plate. And a mechanical generator that inputs the mechanical energy into the generator and generates electrical energy by the generator, and a mooring floating deck that includes the generator. A physical power generation apparatus is provided.

  According to a second aspect of the present invention, the pressure receiving plate integrated with the rotating body according to the first aspect is a disk whose shape is inclined at an appropriate angle on the axis of the rotating body and the center of rotation of the rotating body is projected. The present invention provides a hydrodynamic power generation device characterized in that it is one continuous piece.

  According to a third aspect of the present invention, in the pressure receiving plate integrated with the rotating body according to the second aspect, the flat plate positioned vertically on the rotation center line of the rotating body is inclined at an appropriate angle on the axis of the rotating body. However, the present invention provides a hydrodynamic power generation device that is continuous while being provided.

  According to a fourth aspect of the present invention, the pressure receiving plate integrated with the rotating body according to the second aspect is such that a flat plate that is positioned vertically on the rotation center line of the rotating body and has a part that is inclined and curved in part. The hydrodynamic power generation apparatus is characterized in that it is continuous while being inclined at an appropriate angle on the axis.

  According to a fifth aspect of the present invention, in the hydrodynamic power generation, the rotating body integrated with the pressure receiving plate according to the third and fourth aspects has a conical hollow structure at both ends. A device is provided.

  The invention according to claim 6 is characterized in that the rotating body integrated with the pressure receiving plate according to claim 5 has a mechanism for adjusting on the axis thereof in the vertical direction of the rotation center line. A power generation apparatus is provided.

  Since the present invention is configured as described above, the following effects are exhibited.

  In conventional hydraulic power generation turbines, the pressure receiving portions that receive the energy of the fluid are arranged radially on the rotating shaft in the form shown in FIGS. 8 and 9. Accordingly, the energy of the fluid can be received only intermittently. However, according to the present invention, the pressure receiving plate is inclined at an appropriate angle on the axis of the rotating body and rotated. Since the projected shape of the center of rotation of the body is a single continuous disk-like shape, it is possible to receive the fluid's energy continuously and continuously. To do.

  Further, the pressure receiving portion of the conventional hydroelectric power turbine has a shape as shown in FIG. 8 and FIG. 9, so that the pressure receiving of the energy that the fluid has is limited to the flow in one direction. 3, the pressure receiving plate is a flat plate as shown in FIG. 6 that is inclined while being inclined at an appropriate angle on the axis of the rotating body. The effect of being able to continuously and continuously receive the energy of the fluid corresponding to both the flow in the right direction or the flow in the left direction and the right direction perpendicular to the axial center is exhibited.

  Then, in order to take advantage of the feature that the pressure receiving portion of the conventional hydroelectric turbine as shown in FIG. 8 has a shape with high working efficiency, the present invention is inclined on the axis of the rotating body as described in claim 4. However, since a part of the continuous flat plate has an inclined or curved portion as shown in FIG. 7, the effect that the energy of the fluid can be received continuously and continuously with higher efficiency is exhibited. To do. However, the present invention is most effective for a unidirectional flow parallel to the axis of the rotating body and a unidirectional flow perpendicular to the axis.

  Since the rotating body integrated with the pressure receiving plate of the present invention has a hollow structure as described in claim 5, it can have buoyancy, and its own weight can be adjusted by adjusting L and D shown in FIG. The comparative weight with respect to water and seawater can be brought close to 1: 1, and the load load of the floating deck to be mounted can be reduced as much as possible.

  Therefore, the structure can have a large moment of inertia without being constrained by its own weight, so that the rotating body can maintain extremely smooth rotation without being influenced by the energy level of the fluid due to the instantaneous change in flow velocity. Demonstrate the effect that can.

  Since the rotating body integrated with the pressure receiving plate of the present invention has a conical shape at both ends as described in claim 5, turbulence is unlikely to occur in the fluid flow, and thus the energy of the fluid is impaired. Therefore, the pressure receiving plate can receive the energy with high efficiency.

  Further, the conical portions at both ends serve as a rudder and exhibit an effect of stably maintaining the axis of the rotating body parallel to the fluid flow direction.

  Since the rotating body of the present invention has a mechanism that adjusts in the vertical direction of the center of rotation as described in claim 6, it can be adjusted to a position below the surface of the water where the acting force of energy of the fluid is the highest. And exerts the effect of receiving the maximum amount of energy.

  If a pair of the pressure receiving plates integrated with the rotating body of the present invention in which the inclination direction is symmetrical with respect to the rotation center of the rotating body is used as a pair, each counteracts the reaction force generated by the rotation of each rotating body. By fitting, the floating deck on which the power generation device is mounted exhibits the effect that it can be stably positioned on the water surface.

  The hydrodynamic power generation device of the present invention has a floating deck on which the power generation device is mounted as described in claim 1 and is moored. Therefore, the fluid power generation device can easily move in the vertical direction, and can respond to changes in tide level and water level. Since the energy of the fluid can be stably received, the power can be generated with high efficiency at all times.
