A water turbine device is disclosed. The water turbine device includes a water shaft, a plurality of blade frames, a plurality of turbine blades, a pivot shaft and a blade control mechanism. The water shaft has a first axis. The plurality of blade frames are radially distributed around the water shaft. The plurality of turbine blades are mounted on the plurality of blade frames respectively. The pivot shaft is disposed on a corresponding one of the plurality of blade frames, has a second axis, and allows one of the plurality of turbine blades corresponding to the corresponding blade frame to be pivotally mounted on the corresponding blade frame. The blade control mechanism is disposed on an end opposite to the pivot shaft on the corresponding blade frame, wherein the turbine blade mounted on the corresponding blade frame has a stopper adjacent to the blade control mechanism.

1. A water turbine device, comprising: a water shaft having a first axis;a plurality of blade frames radially distributed around the water shaft;a plurality of turbine blades mounted on the plurality of blade frames respectively;a pivot shaft disposed on a corresponding one of the plurality of blade frames, having a second axis, and allowing one of the plurality of turbine blades corresponding to the corresponding blade frame to be pivotally mounted on the corresponding blade frame; andan axially extending body disposed on an end opposite to the pivot shaft on the corresponding blade frame, wherein the turbine blade mounted on the corresponding blade frame has a stopper adjacent to the axially extending body, and the first axis and the second axis are parallel to each other. 2. The water turbine device as claimed in claim 1, wherein the stopper protrudes from the turbine blade. 3. The water turbine device as claimed in claim 2, wherein the axially extending body includes a gap portion, so that when the axially extending body moves to allow the gap portion to align with the stopper, the stopper can freely pass through the axially extending body. 4. The water turbine device as claimed in claim 3, further comprising: a stopper release mechanism being a roller, adjacent to the axially extending body, wherein the stopper release mechanism contacts and causes the axially extending body to no longer abut against the turbine blade; anda stopper actuating mechanism being a roller, adjacent to the axially extending body, wherein the stopper actuating mechanism contacts and causes the axially extending body to abut against the turbine blade. 5. The water turbine device as claimed in claim 4, wherein the stopper release mechanism and the stopper actuating mechanism are disposed beside the water channel. 6. A control mechanism for controlling a water turbine device, wherein the water turbine device comprises a water shaft having a first axis, a plurality of blade frames radially distributed on the water shaft, a plurality of turbine blades mounted on the plurality of blade frames respectively, and a pivot shaft having a second axis and disposed on a corresponding one of the plurality of blade frames to allow one of the plurality of turbine blades corresponding to the corresponding blade frame to be pivotally mounted on the corresponding blade frame, wherein the first axis and the second axis are parallel to each other, and the control mechanism comprises: a stopper disposed on the turbine blade mounted on the corresponding blade frame and mounted thereon the pivot shaft; andan axially extending body, wherein under a first condition, the control element abuts against the stopper to restrain a pivot turn of the turbine blade, and under a second condition, the control element releases an abutment with the stopper to allow the turbine blade to pivot relative to the corresponding blade frame. 7. The control mechanism as claimed in claim 6, wherein the stopper is a free end of the turbine blade. 8. The control mechanism as claimed in claim 7, wherein the stopper protrudes from the turbine blade. 9. The control mechanism as claimed in claim 6, wherein the axially extending body includes a gap portion, so that when the axially extending body moves to allow the gap portion to align with the stopper, the stopper can freely pass through the axially extending body. 10. The control mechanism as claimed in claim 6, further comprising: a first push portion disposed at one end of the axially extending body, wherein when the first push portion is pushed, the axially extending body changes from the first condition to the second condition, and thereby releases the abutment with the stopper; anda second push portion disposed at the other end of the axially extending body and opposite to the first push portion, wherein when the second push portion is pushed, the axially extending body changes from the second condition to the first condition, and restores the abutment with the stopper to restrain the pivot turn of the turbine blade. 11. The control mechanism as claimed in claim 10, wherein the first push portion and the second push portion have a camber shape. 12. The control mechanism as claimed in claim 10, wherein the water turbine device is configured in a water channel. 13. The control mechanism as claimed in claim 10, wherein the axially extending body further includes: a stopper release mechanism being a roller, disposed beside the water channel and adjacent to the first push portion, wherein the stopper release mechanism contacts and pushes the first push portion. 14. The control mechanism as claimed in claim 10, wherein the axially extending body further includes: a stopper actuating mechanism being a roller, disposed beside the water channel and adjacent to the second push portion, wherein the stopper actuating mechanism contacts and pushes the second push portion. 15. The control mechanism as claimed in claim 10, wherein the axially extending body further includes a transition portion disposed between the first push portion and the second push portion.
