Abstract

A water turbine device is provided which can move a water turbine from a use position to a nonuse position with a light force, and which has a simplified structure. An intermediate portion of a suspension support rod for suspending a water turbine immersed in a flowing water in a waterway is pivotally attached to a platform provided on the waterway with a horizontal shaft, and a power generation device as a balance weight is provided at the free end of the suspension support rod, and the water turbine is rotatable around the horizontal shaft between the use position where the water turbine is immersed in a flowing water and the nonuse position above the flowing water.

Claims

1. A water turbine device comprising:

a platform provided on a waterway;

a suspension support rod for suspending a water turbine that can be immersed in a flowing water in the waterway, an intermediate portion of the suspension support rod is pivotally attached to the platform with a horizontal shaft; and

a balance weight provided at the free end of the suspension support rod,

wherein the water turbine is configured to be rotatable around the horizontal shaft as a center between a use position where the water turbine is immersed in a water flow in the waterway and a nonuse position above the water flow in the waterway.

2. The water turbine device according to claim 1,

wherein the balance weight is a power generation device connected to the water turbine by power transmission means provided in the suspension support rod, and the power generation device generates power by the rotational force of the water turbine.

3. The water turbine device according to claim 1,

further comprising a fixing means for fixing either one of the suspension support rod, the balance weight, or the water turbine to the platform in a state where the water turbine is located at the nonuse position.

4. The water turbine device according to claim 1,

wherein the balance weight is detachably attached to the suspension support rod, or the balance weight and a part of the suspension support rod are detachably attached to the other part of the suspension support.

5. A hydroelectric power generation device comprising:

a support base provided on a waterway;

a pair of left and right shaft supports provided on the support base; and

a suspension support body fixed to an upper surface of a water turbine housing, an upper part of the suspension support body is hung and fixed vertically to the pair of shaft supports through a horizontal hanging shaft,

wherein the water turbine housing is configured to be rotatable around the horizontal shaft as a center and can be pulled up onto the support base.

6. The hydroelectric power generation device according to claim 5,

wherein a downward bearing groove is formed in the center part in the front and rear of an upper surface of the shaft supports, and

wherein the horizontal hanging shaft provided on an upper edge part of the suspension support body is configured to be inserted into the downward bearing groove from the top and supported therein.

7. The hydroelectric power generation device according to claim 5,

wherein on the upper surface of the suspension support body, a hook for hanging the water turbine housing is formed.

8. The hydroelectric power generation device according to claim 5,

wherein on the upper portion of the suspension support body, a lever rod for swinging the water turbine housing around the horizontal hanging shaft is detachably mounted.
