The present invention relates to a hydroelectric power generation device that can obtain highly efficient electric power.

  In recent years, as a clean energy, a large number of hydroelectric generators are installed in the inflow and outflow pipelines in buildings. However, since the amount of drainage is generally small, there is a situation where the desired amount of power generation cannot be obtained. It was.

  For this reason, conventionally, for example, as disclosed in Patent Document 1, a required amount of power generation can be obtained, the drainage channel is not clogged, and the drainage channel is further improved in maintainability. A technology called a hydroelectric power generation system has been proposed.

  This system comprises a hydroelectric generator comprising a field magnet disposed in a collecting pipe of a drainage channel and rotated by drainage, and a coil arranged around the collecting pipe and interlinked with the magnetic flux of the field magnet. And a charge control device for rectifying and smoothing the AC voltage generated in the coil to obtain a predetermined DC voltage.

At the same time, the battery is charged by this DC voltage.

JP 2007-205217 A

  However, in the case of the drainage hydroelectric power generation system shown in Patent Document 1 described above, an AC voltage is induced in the coil by rotating the field magnet in a certain direction only by a head of water that naturally falls from the collecting pipe, and this AC Since the voltage is rectified and smoothed by the charge control device and converted to a DC voltage of a predetermined magnitude, the field magnet cannot be efficiently rotated, and instead the field magnet acts as a resistance, For this reason, there has been a problem that sufficient battery charging cannot be performed.

  Therefore, the present invention has been created in view of various circumstances existing in the past, and a plurality of water flow introduction portions are arranged inside a rotating body in a drive turbine, and water flow is vigorously ejected from the water flow ejection portion. An object of the present invention is to provide a hydroelectric power generation device that can rotate a rotating body of a driving turbine at a high speed by the jetted water flow and obtain sufficient electric power by a generator.

  In the present invention, a generator and a water flow introduction body are arranged inside a cylindrical body, and a vertical drive turbine having a central rotating shaft arranged so as to penetrate the water flow introduction body is rotatably attached. A hydroelectric generator that rotates a drive turbine by a water flow ejected from a water flow introducing body and obtains electric power from a generator linked to a central rotating shaft, and the water flow is placed on a peripheral wall of the water flow introducing body, A plurality of water jets that jet in a specific horizontal direction are provided so that the drive turbine has a rotating body that has a plurality of turbine blades erected in an arc shape and is formed into a substantially cylindrical shape as a central rotating shaft. The above-described problems have been solved by being configured so that the rotating body of the driving turbine is disposed so as to surround the water flow ejection portion of the water flow introducing body.

  Moreover, the problem mentioned above was similarly solved by providing the water-flow ejection part in four places in the surrounding wall of a water-flow introduction body.

  Further, each water jetting portion provided on the peripheral wall of the water flow introducing body jets a water flow toward the turbine blade of the rotating body located outside, and the rotating body of the driving turbine is driven by the collision force of the water flow against the turbine blade. By rotating, the same problem as described above was solved.

  In addition, each water jetting part provided on the peripheral wall of the water flow introducing body jets a water flow toward the turbine blades of the rotating body located outside, and turns around the water flow introducing body inside the cylindrical body. The above-mentioned problem was solved by generating a flow and rotating the rotating body of the drive turbine by this swirling flow.

  In addition, each water jet part provided on the peripheral wall of the water flow inlet body jets the water stream toward the turbine blades of the rotating body located on the outside, and the collision force of water against the turbine blades and the cylindrical part body The above-mentioned problem was solved by rotating the rotating body of the drive turbine by the swirl flow generated around the water flow introducing body inside.

  In addition to this, each water jet part provided on the peripheral wall of the water flow introducing body jets a water flow toward the turbine blades of the rotating body located on the outside, and the rotating body of the driving turbine by the collision force of the water flow against the turbine blades Therefore, the direction of the water flow (specific horizontal direction ... left side) and the rotation direction of the rotating body (left rotation) must be the same when the water flow is ejected vigorously from each water jet part. Thus, the rotating body of the driving turbine can be rotated at a high speed by the jetted water flow.

  In addition, each water jetting part provided on the peripheral wall of the water flow introducing body jets a water flow toward the turbine blades of the rotating body located outside, and turns around the water flow introducing body inside the cylindrical body. Since the rotating body of the drive turbine is rotated by this swirl flow, even if the water flow ejected from each water flow ejection portion does not have a predetermined momentum, for example, The rotating body can be reliably rotated.
