Abstract

A hydroelectric power generation apparatus includes a hydroelectric power generation module, a beam as a supporting part, and a fixing part. The hydroelectric power generation module includes a rotary blade and a power generator that generates power by rotation of the rotary blade. The supporting part supports the hydroelectric power generation module. The fixing part fixes the supporting part to a water channel. The fixing part includes a bolt to press a surface of a wall portion of the water channel to fix the supporting part to the water channel. The hydroelectric power generation apparatus can dispense with a work performed around the water channel to install the apparatus and also be relocated easily and inexpensively.

First claim

The invention claimed is:

1. A hydroelectric power generation apparatus comprising:
a hydroelectric power generation module including a rotary blade and a power generator configured to generate power by rotation of the rotary blade;
a supporting part that supports the hydroelectric power generation module; and
a fixing part that fixes the supporting part to a water channel,
wherein the fixing part includes a plate-shaped member a bolt, and
wherein the plate-shaped member is pressed against a wall surface of the water channel using the bolt such that the plate-shaped member is disposed between a tip of the bolt and the wall surface of the water channel.

2. The hydroelectric power generation apparatus according to claim 1 , wherein the fixing part includes:
a base member having a threaded hole to receive the bolt; and
a nut connected to the bolt.

3. The hydroelectric power generation apparatus according to claim 1 ,
wherein the fixing part includes a L-shaped base member,
wherein the L-shaped base member includes 1) a bolt hole, 2) a first member fixed to the supporting part, and 3) a second member including the bolt hole for receiving the bolt, and
wherein the bolt is inserted into the bolt hole of the second member of the L-shaped base member.

4. The hydroelectric power generation apparatus according to claim 1 ,
wherein the plate-shaped member has a step,
wherein the tip of the bolt is in contact with the step of the plate-shaped member.

5. The hydroelectric power generation apparatus according to claim 1 , wherein the plate-shaped member has a recess to receive the tip of the bolt.

6. The hydroelectric power generation apparatus according to claim 1 , wherein the fixing part is displaceably connected to the supporting part.

7. The hydroelectric power generation apparatus according to claim 1 , wherein the rotary blade is a horizontal-axis-type, propeller-type rotary blade.

8. The hydroelectric power generation apparatus according to claim 1 , wherein the rotary blade is a vertical-axis-type rotary blade.

9. A hydroelectric power generation apparatus comprising:
a hydroelectric power generation module including a rotary blade and a power generator configured to generate power by rotation of the rotary blade;
a supporting part that supports the hydroelectric power generation module; and
a fixing part that fixes the supporting part to a water channel,
wherein the fixing part includes 1) a plate-shaped member including a step and 2) a bolt to press the plate-shaped member against a wall surface of the water channel such that i) a tip of the bolt is in contact with the step of the plate-shaped member and ii) the plate-shaped member is disposed between the tip of the bolt and the wall surface of the water channel.

10. A hydroelectric power generation apparatus comprising:
a hydroelectric power generation module including a rotary blade and a power generator configured to generate power by rotation of the rotary blade;
a supporting part that supports the hydroelectric power generation module; and
a fixing part that fixes the supporting part to a water channel,
wherein the fixing part includes 1) a plate-shaped member including a recess and 2) a bolt to press the plate-shaped member against a wall surface of the water channel such that i) the recess of the plate-shaped member receives a tip of the bolt and ii) the plate-shaped member is disposed between the tip of the bolt and the wall surface of the water channel.
