Adopt the utility model discloses the hydraulic turbine, rivers flow through the hydraulic turbine by water inlet end 10, and arc guide plate 4 is located the bottom side of cylinder 1, the length of arc guide plate 4 is greater than or equal to the length of cylinder 1, and form the sluicing passageway between arc guide plate 4 and the cylinder 1, guarantee from this that rivers all can flow over along arc guide plate 4, and the water that flows out by water inlet end 10 flows through along the sluicing passageway and flows out along the water outlet end, rivers rotate cylinder 1 through movable blade 5 when flowing through, thereby convert the gravitational potential energy of water into cylinder 1 pivoted mechanical energy, power shaft 2 external power generation facility converts mechanical energy into electric energy storage afterwards, and then realize converting hydroenergy into electric energy; specifically, when the movable blade 5 rotates along with the roller 1 and does not enter the drainage channel, the control device controls the second side of the movable blade 5 to be connected with the locking device, so that the movable blade 5 is in a retracted state when entering water from the air, the movable blade 5 is in contact with the water flow, because the contact area between the movable blade 5 and the water flow is small, the reverse resistance of the water flow on the movable blade 5 is small, thereby reducing unnecessary water energy loss, when the movable blade 5 enters the drainage channel, the control device enables the second side of the movable blade 5 to be separated from the locking device and to be far away from the fixed frame 3 outside the roller 1, at the moment, the second side of the movable blade 5 is a movable side, and the water flow impacts the movable blade 5 to enable the second side of the movable blade 5 to be abutted against the outer wall surface of the roller 1 and form a water blocking groove, the movable blade 5 is always in an, namely, the movable blade 5 is abutted against the outer wall surface of the roller 1 to form a water blocking groove, and the two ends of the water blocking groove are the left side plate 31 and the right side plate 32, so that the water blocking groove, the left side plate 31 and the right side plate 32 form a water blocking chamber, water flow in the water blocking chamber flows from a high position to a low position to further drive the roller 1 to rotate, thereby the gravitational potential energy of water is fully converted into mechanical energy for rotating the roller 1, when the movable blade 5 comes out from the water drainage channel and continues to rotate, the second side of the movable blade 5 is gradually connected with the locking device, namely after the movable blade 5 rotates out from the water drainage channel, the movable blade 5 is fixedly connected with the fixed frame 3 again, namely when the movable blade 5 is positioned outside the water drainage channel, the second side of the movable blade 5 is connected with the locking device, and then until the movable blade 5 rotates to the inlet of the water drainage channel again, the movable blade 5 is opened again, thereby achieving the cyclic operation of opening and retracting the movable blade 5. To sum up, because above-mentioned structure can guarantee that movable blade 5 is in the state of packing up when entering into to the aquatic by the air, can not make 1 pivoted mechanical energy loss of cylinder be used for overcoming huge rivers reverse resistance this moment, thereby improved the conversion rate of hydroenergy, and can not beat rivers and cause the noise and damage movable blade 5 because of movable blade 5, make long service life and the steady operation of hydraulic turbine, in addition, movable blade 5 is in the state of opening completely in sluicing passageway department, the water blocking groove of its formation makes rivers can not spill over and promote cylinder 1 better from this and rotate, the utilization ratio of hydroenergy has further been mentioned.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "top", "bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
