Description

  The present invention relates to a hybrid compact power generator that generates power using hydropower and wind power.

  2. Description of the Related Art Conventionally, an apparatus that stably generates power by combining natural energy such as wind power generation, hydroelectric power generation, and solar power generation has been devised.

  In a small power generator, a device capable of generating power stably and efficiently even with a small amount of wind power or hydraulic power is required.

  In order to generate power using the natural energy of conventional wind power generation or hydroelectric power generation, it is necessary to select and install a place where the wind is strong and the water flow is large. On the other hand, a small power generator is required to be installed near a place where the generated electricity is used. If the wind is strong and there is no place with a large water flow, a small power generator can be widely used if power can be generated even with a low wind or a small water flow.

  In addition, installation work is required to install the power generation device, and it takes a lot of time and money to install.

  In order to solve such problems, the present invention provides two types of blades for wind power generation, one is a Saponius type that rotates even in low winds, and the other is efficient rotation when wind power becomes strong. Adopting a vertical shape, the vertical axis of the wind turbine's rotating shaft is coupled by a one-way clutch mechanism.

  Further, a helical water turbine for hydroelectric power generation is provided, and the generator is rotated through a mechanism for transmitting the rotation shaft of the water turbine from the rotation shaft of the vertical wind turbine. The generator has a configuration in which the internal magnet arrangement is rotated by 90 degrees in the direction of the magnetic poles of adjacent magnets.

  The power generation device having the above-described configuration is configured above and below the base plate, and a floating body 21 is provided below the base plate, and power generation is performed by floating the power generation device over river or sea water.

  According to the present invention, it is possible to provide a small power generator that can efficiently generate power even in a light wind or a small water flow and does not require installation work.

The small generator includes a tail 1, a cover 2, a saponius wind turbine 3, a vertical vane wind turbine 4, and a first generator. The rotating shaft 5, the one-way clutch 6, the generator 7, the second rotating shaft 15, the helical water turbine 16, the power generation base plate 13, and the floating body 21 are included.

  The Saponius wind turbine 3 is coupled to the first rotating shaft 5.

  The Saponius type windmill 3 is characterized by being able to rotate even in a weak wind due to the blade structure. Further, a tail blade 1 is provided on the upper part of the Saponius wind turbine 3, and the wind is blocked by the cover 2 on the front side opposite to the rotation direction of the Saponius wind turbine 3 with respect to the windward direction in accordance with the moving direction of the tail blade 1. It has a structure. By adopting the above-described structure, wind is applied only in the rotation direction, and the Saponius wind turbine 3 rotates efficiently.

  When the top view of the Saponius wind turbine 3 is shown in FIG. 2, the blades 31 of the Saponius wind turbine are arranged in a circle with respect to the rotation axis. In addition, a cover 32 is provided on the right side from the wind direction, and the cover 32 also changes the direction in conjunction with the tail blade 33 changing the direction according to the wind direction.

  In FIG. 1, the first rotary shaft 5 is provided with a vertical blade type windmill 4 via a one-way clutch 6. The vertical vane wind turbine 4 is also configured to block the wind with the cover 2 on the right front side from the wind direction of the vertical vane wind turbine 4 in accordance with the moving direction of the tail blade 1 above the Saponius wind turbine 3. . By adopting the above structure, the wind is applied only in the rotation direction, and the vertical blade type windmill 4 is efficiently rotated.

  FIG. 3 is a top view of the vertical blade type windmill 4. The vertical blade type windmill 4 has a cylindrical shape as a whole, and the blades 41 are arranged in a circle with respect to the rotation axis. Further, a cover 42 is provided on the right side from the wind direction, and the cover 42 also changes its direction in conjunction with the direction of the tail 1 changing its direction according to the wind direction.

  In FIG. 1, the one-way clutch 6 transmits the torque of the vertical vane wind turbine 4 to the first rotary shaft 5 when the vertical vane wind turbine 4 rotates faster than the first rotary shaft 5. On the contrary, when the vertical blade type windmill 4 rotates slower than the first rotating shaft 5, the torque of the vertical blade type windmill 4 is not transmitted to the first rotating shaft 5. That is, during the period when the wind is weak, the rotation of the Saponius wind turbine 3 rotates faster than the rotation of the vertical vane wind turbine 4, so that the first rotating shaft 5 rotates with the rotational torque of the Saponius wind turbine 3, and the wind When the rotational speed of the vertical blade wind turbine 4 rotates faster than the rotational speed of the Saponius wind turbine 3, the rotational torque of the vertical blade wind turbine 4 is transmitted to the first rotary shaft 5, The rotating shaft 5 is rotated by the rotational torque of the vertical blade wind turbine 4 and the rotational torque of the Saponius wind turbine 3.

  The first rotary shaft 5 is provided with a first pulley 8 and is coupled to a second pulley 10 via a belt 9, and the second pulley 10 is connected to the generator 7 via an electromagnetic clutch 11.

A signal generated by the rotation sensor is connected to the control panel 20, and the control panel 20 controls the electromagnetic clutch 11.

  The electromagnetic clutch 11 operates to transmit the rotation of the pulley 10 to the shaft of the generator 7 when the rotation speed of the second pulley 10 exceeds a specified value. That is, when the rotational speed is less than the torque for rotating the generator 7, the rotation of the Saponius wind turbine 3 is separated from the generator 7 by the electromagnetic clutch 11, and the rotational speed of the Saponius wind turbine 3 is a specified value. When it becomes above, it connects with this electromagnetic clutch 11. With this method, the generator 7 can be reliably started.
