Description

  The present invention relates to an apparatus for generating electricity using the energy of water, which is installed throughout a mountainous area, where water constantly flows from a river dam.

  Conventionally, in order to obtain electric energy, nuclear power, solar power, wind power, and solar power generation have some problems such as damage to the natural environment and excessive loss of green. In particular, nuclear power generation still has some problems that cannot be solved even by applying world technologies. In addition, generation of carbon dioxide from fossil fuels has become serious as a cause of global warming.

Japanese Patent Laid-Open No. 7-207649 JP 2011-43126 A

The problem to be solved is to provide a stable and high output of electric energy by utilizing the abundant infinite energy and water flow of Japan without damaging the beautiful green environment of nature. to reduce emissions, is that the responsible for the over end of global warming prevention.

The hydroelectric power generation device according to the present invention includes a water channel that branches off from a river dam, a water turbine that rotates by water flowing down the water channel, and a generator that generates power when the rotation of the water turbine is transmitted.
The waterway extends almost horizontally from the branching position with a slight gradient and then is bent down at an angle close to the vertical, and is integrated into one end in the width direction of the bottom and extends substantially vertically to the upstream side of the river. A mountain-side wall that is located, a valley-side wall that is integrated with the other end in the width direction of the bottom and extends substantially vertically and is located on the downstream side of the river, and is continuous to the valley-side wall and downstream along the waterway and on the bulk extending, Ru equipped with.
The top wall of the mountain side is approximately the same height as the top of the dam, and the top wall of the valley side is lower than the top wall of the valley. It is formed to be able to get over the water flowing through the river approximately equal to the height of the upper end of the wall.
The rotation axis of the water turbine is arranged on the dam side rather than the portion bent at a near-vertical angle at the bottom supported by the mountain side wall and the valley side wall.
Waterwheel Since the "rotation by the water flowing down the canal", is Installation naturally consuming fallen water waterways position.
In addition, the “top” in the present invention refers to the highest portion (reference numeral 23 in FIGS. 2 to 4) of the dam, as in the case of the usual “top” in the field of civil engineering. .

Side walls of the channel to rotate the water wheel is to increase the sidewall of waterways mountain from the valley side, not the side walls water waterways mountain side even when the flood and overflow. Water wheel is supported by two of the walls of the valley side and the mountain side.

Hydropower device according to the present invention, By raising the "excluding waterway" portion of the dam, always stable amount of water Ru flows through the water channel. The water turbine for rotating the generator always maintains a stable rotation, and in the event of a flood, it flows downstream regardless of the water channel and raised part, and is also affected by various fluids that flow in mixed turbulence. The water turbine always maintains a stable rotation.

The turbine blades that rotate by absorbing the energy of the water falling in the waterway are made of a material that does not produce any sound other than the sound of natural water flowing down, even in turbid flows mixed with pebbles during a flood.

For adjusting the rotation of the water wheel in the rotational force necessary for power generation, water turbine is connected to the acceleration pulley, adjusted the generator generates power to rotational force necessary for power generation.

  If you set up a sluice in the canal and close the sluice in that canal, the water flow will pass over the raised part and flow down to the waterhole.

By converting the energy of water flowing down from the dam, which is provided throughout the mountain The inter into electrical energy, and there is no need to send electricity from remote locations to the various facilities of the mountainous areas that use electricity . Reverse to send the electricity surplus be used in the facility of the mountainous areas in the town, by the use of electricity in the town, too lost while there natural environment and can be responsible for an end of global warming prevention.

Hereinafter, have One to an embodiment of the apparatus for generating power by utilizing energy from water flowing off the weir of the present invention will be described with reference to the drawings.

Figure 1 is a plan view of a hydropower device according to the present invention. FIG. 2 is a cross-sectional view of FIG. FIG. 3 is a cross-sectional view of FIG. FIG. 4 is a cross-sectional view of FIG. 1 viewed from the C-C plane.
As shown in FIGS. 3 and 4 , walls 4 and 5 having different heights are grounded at two places, a valley-side wall 4 supporting the water channel 3 at the top end 2 of the dam 1 and a raised mountain-side wall 5. As shown in the top 2 of FIG. 3 and 4, the water channel 3 is installed with a slight inclination toward the downstream, and the water channel 3 is bent down at an angle 6 near the middle along the way. A water turbine 11 having a pulley 9 attached to a rotary shaft 10 for rotating the generator 8 is installed at a position where the generator 7 falls.

For supplying the water to maintain a stable rotation of the water wheel 11 to the water channel 3, "except water channel 3" crest 2 of the dam 1 moiety By bulk on up (bulk on 12), constantly stable in the water channel 3 Thus, the water turbine 11 in the water channel 3 always maintains a stable rotation and rotates.

Further, when the flood water to flow downstream without distinction waterways 3, raising unit content (bulk on 12), the water wheel 11 will always maintain a stable rotation.

The blade 14 of the water wheel 11 that rotates by absorbing the energy of the water flow 7 falling on the water wheel 11 in the water channel 3 is a material that does not produce any sound other than the sound of the natural water flow that flows down even in a muddy flow mixed with pebbles during a flood. using the blade 14 of the 11, to the rotary shaft 10 of the water wheel 11 that is equipped with a pulley 9 for connection for rotating the generator 8.

  In order to adjust the rotation of the water turbine 11 to a rotational force necessary for power generation, the turbine 11 is connected to the acceleration pulley 15 and connected to the generator 8 with the adjusted rotational force to generate power.

The waterways provide a floodgate, when closing the sluice of the waterway, water 7 flows down to the basin 13 beyond raising unit content (the bulk on 12).
