Problems solved by technology

[0009] However, in the conventional technology, since the entire vertical-axis hydroelectric power generation device including the generator is supported by the floating body, a large floating body capable of obtaining sufficient buoyancy is required.
Therefore, there is a problem of increasing the size of the device
In addition, since the entire vertical-axis hydroelectric power generation device floats on the water surface, the attitude of the entire device including the water turbine becomes unstable, and there is a problem that power generation tends to become unstable.
In addition, since the overall posture of the device is unstable, there is a problem that maintainability and reliability are inferior.

Embodiment Construction

[0028] figure 1 It is a figure which shows the schematic structure of the vertical axis type hydroelectric power generation apparatus 1 which concerns on embodiment of this invention.

[0029] figure 2 It is a figure which shows the movement guide part 30 and the fixed part 50.

[0030] The vertical-axis hydroelectric power generation device 1 is installed, for example, in a canal C used in agriculture, industry, waterways, and the like.

[0031] In the vertical axis type hydroelectric power generation device 1 , the vertical axis type water turbine 10 is disposed below the water surface Ws of the canal C. As shown in FIG. The vertical axis type water turbine 10 is disposed in a channel C so as to be submerged in water.

[0032] The vertical axis type water turbine 10 is arranged such that the central axis (rotation center) A of the rotating shaft 13 faces the vertical direction. A generator 55 is indirectly connected to a portion of the rotating shaft 13 that is exposed ...

Abstract

The hydroelectric power generation equipment (1) is provided with: a water wheel (10) that is disposed below the water surface (Ws); a power generator (55) for generating power using the rotation of the water wheel (10); a movement guiding unit (30) that comprises a shaft (31), which is disposed coaxially with the center of rotation (A) of the water wheel (10), and is capable of transmitting the rotation of the shaft (31) to the power generator (55) while moving the shaft (31) in the direction of the axis of rotation of the power generator (55); and a water wheel position-adjusting unit (60) for moving the shaft (31) in the vertical direction to match variations in the water level (Ws).

Description

technical field [0001] The invention relates to a hydroelectric power generation device. [0002] this application claims priority based on Japanese Patent Application No. 2012-176500 for which it applied to Japan on August 8, 2012, and uses the content here. Background technique [0003] In a power generation device using a vertical-axis turbine (tubular turbine), even if the water level (water surface) changes up and down, the turbine (blade portion) must always be placed below the water surface (submerged in water). When a part of the water turbine is exposed on the water surface, the load applied to the water turbine becomes uneven, which may cause malfunction of the water turbine. [0004] In this regard, the following technology has been proposed: by fixing the generator to a floating body floating on the water surface, and arranging the water turbine on the bottom surface side (lower side) of the floating body, the vertical axis type water turbine is always arranged ...
