Description

  The present invention relates to a vertical hydroelectric power generation apparatus that generates electric power using the potential energy of water.

  Hydroelectric power generation is the conversion of energy by moving an object with potential energy due to the gravity drop of water in rivers, lakes, dams, etc. located upstream. Normally, water in rivers, dams, etc. located upstream. The power is generated by moving the blades to the low position.

  As shown in FIG. 4, the existing hydroelectric generator has a water storage unit 50, a water flow passage 60, and a power generation unit 70, and the water flow passage 60 is obliquely downward so as to communicate with the water storage unit 50. The power generation unit 70 is installed so as to communicate with the lower end of the water flow passage 60, and a shaft 71 is vertically attached to a lower portion thereof, and a blade 72 is rotatably attached to the shaft 71. According to this configuration, when power is generated, the water stored in the water storage unit 50 is caused to flow obliquely downward from the water flow passage 60 by gravity, and the blade 72 of the power generation unit 70 is rotated to generate power.

  However, since the water flow passage in the existing hydroelectric power generation device extends obliquely downward, the impact force of the water flow is divided into a vertical force and a horizontal force. In addition, the existing hydroelectric generator can generate power by rotating the blades with a horizontal force, but cannot rotate the blades with a vertical force and does not friction with the inner wall of the water passage. As a result, the impact force of the water flow is weakened, and the power generation efficiency is lowered.

The vertical hydroelectric generator according to the present invention is
A water storage unit with an internal water storage space;
A water flow passage which is installed so as to communicate with the water storage unit and has a lower opening formed downward;
A power generation unit including a shaft installed below the water storage unit and attached in a lateral direction, and a plurality of blades attached to the shaft in an annular manner at intervals to correspond to the lower opening of the water flow passage. Is.

  In such a vertical hydroelectric generator, the water flow passage includes a lateral portion and a longitudinal portion, and the lateral portion is attached so as to communicate with the water storage unit, and the longitudinal portion is an end of the lateral portion. In addition, the inner diameter of the horizontal portion is larger than the inner diameter of the vertical portion, and the bonding portion between the horizontal portion and the vertical portion has a trumpet shape in cross section. Is preferred.

  In such a vertical hydroelectric generator, it is preferable that the guide passage extends downward so as to communicate with the lower opening of the water passage.

  In such a vertical hydroelectric generator, a drainage unit is connected to the power generation unit, the drainage unit includes a shell and a drainage passage communicating with the shell so as to extend in a lateral direction, and a plurality of the power generation units The blades are preferably housed inside the shell.

  In such a vertical hydroelectric generator, the blades are preferably installed so as to bend clockwise or counterclockwise.

  In the vertical hydroelectric power generator of the present invention, since water falls vertically by gravity after flowing in the horizontal direction, there is no horizontal force at the time of dropping, and the frictional force with the inner wall of the guide passage 40 is reduced. , Greater potential energy can be transmitted to the blades 25 to improve power generation efficiency.

It is a partial expanded sectional view which shows the upper opening and lower opening of a water flow path in the vertical hydroelectric generator which concerns on this invention. It is a front view of the axis | shaft and blade | wing of a power generation unit in the vertical type hydroelectric generator which concerns on this invention. It is side surface sectional drawing of the existing hydroelectric generator.

  As shown in FIGS. 1 and 2, the vertical hydroelectric generator according to the present invention includes a water storage unit 10, a water flow passage 12, a power generation unit 20, a drainage unit 30, and a guide passage 40.

  Among them, the water storage unit 10 is provided with a water storage space 11 for storing water therein, and may be a dam or a water tower. The water flow passage 12 is installed so as to communicate with the water storage unit 10, The horizontal direction part 121 and the vertical direction part 122 are provided, and this horizontal direction part 121 is attached to the upper part of the water storage unit 10 so that it may connect with the water storage space 11, and the one part exhibits a semicircle, this vertical direction The direction part 122 extends vertically and downward from the end of the horizontal part 121 so as to communicate with the horizontal part 121, and a lower opening is formed downward at the lower end thereof. Is larger than the inner diameter of the vertical portion 122, and the bonding portion between the horizontal portion 121 and the vertical portion 122 has a trumpet shape or a funnel shape. In the present embodiment, it is preferable that the upper opening is formed upward at a location where the lateral portion 121 and the longitudinal portion 122 in the water flow passage 12 are in contact with each other.

  The power generation unit 20 is installed below the water storage unit 10, and includes a case 21, a stator 22, a rotor 23, a shaft 24, and a plurality of blades 25. The stator 22 is attached to the case 21, the rotor 23 is rotatably attached to the stator 22, and the shaft 24 is parallel to the lateral portion 121 of the water storage unit 10. The blades 25 are attached to the rotor 23 in the lateral direction, and the plurality of blades 25 are annularly attached to the shaft 24 at intervals so as to correspond to the lower opening of the longitudinal portion 122 of the water flow passage 12. Further, as shown in FIG. 3, each of the blades 25 is annularly attached to the outer peripheral surface of the shaft 24 so as to bend clockwise or counterclockwise. Strikes the blade 25 and the shaft 24 rotates to rotate the rotor 23 relative to the stator 22 to generate electricity.

  The drainage unit 30 is connected to the power generation unit 20 and includes a shell 31 and a drainage passage 32, and is installed in the shell 31 so that the shaft 24 and the blades 25 in the power generation unit 20 are accommodated. The drainage passage 32 extends laterally from a lower portion on one side so as to communicate with the shell 31. The drainage passage 32 in this embodiment is a tubular pipe that communicates with the shell 31, and guides the water from the shell 31 to flow into the river, or sends it to other water storage devices for circulation. be able to.

  The guide passage 40 is installed between the water passage 12 and the drainage unit 30 so as to communicate with the lower opening of the water passage 12. In this embodiment, the upper end of the guide passage 40 is mounted on the longitudinal portion 122 of the water flow passage 12 and the lower end corresponds to the shell 31 of the drainage unit 30 so as to correspond to the blades 25 of the power generation unit 20. Connected. According to this configuration, the water stored in the water storage unit 10 flows into the shell 31 from the guide passage 40 through the water flow passage 12 and rotates against the blades 25 of the power generation unit 20. There is no slippage due to air resistance.

  As shown in FIG. 1, when the present invention is actually used, if the water stored in the water storage unit 10 is about to overflow, the water flows in the horizontal direction through the horizontal portion 121 of the water flow passage 12 and then in the vertical direction. To the unit 122. At this time, water falls in the vertical direction due to gravity, passes through the guide passage 40, hits the blade 25 in the vertical direction, and generates power by the power generation unit 20.
