Hydroelectric generator

This invention is made of a rotational hollow blade ( 11 ) turbine, which can be installed in watercourses for power generation. This system may include up to six propellers placed in hexagon shape, since this is the recommended shape for a better collection of the river flow, so that their movement does not obstruct the turbine rotation, and increases speed when immersing and emerging. The mentioned propellers are assembled on top of an axis of rotation, and the latter has an emission pinion ( 12 ) on both ends, which connects to a receiver pinion ( 13 ) placed inside a reduction gear box. Several turbines can be installed depending on the motive power of each hydric flow, and on the connection to two flow generators, one on each side, so that the power falling upon the turbine is regular and balanced.

Improvements relating to high speed water turbines for low heads

245,583. Bovine & Co., Ltd., and Cook, H. D. Dec. 24, 1924. Regulating. - The angularity of the runner blades b of a highspeed water turbine is automatically adjusted according to the head of water, and also, if desired, according to the load. Float or other mechanism l, m, l<1> m<1>, n, o actuated by differences in level in the head and tail races operates a pivoted cam i bearing on a roller h at the end of a rod e. This rod e adjusts the angularity of the blades b directly or through a servo-motor. The usual governor-control may be superimposed by making the pivot member k of the cam i slidable and causing a pivoted cam s to bear on a roller q on the pivot member, the cam s being displaced by a governor-controlled servo-meter d. In place of the two cams i, s, a single governor-rocked cam r, Fig. 3, may be used, having its pivot displaceable along a curved slotway w by the float-displaced rod o. Alternatively, the rod o may displace the point of connection of the governor-displaced rod u. In a further modification, the pivoted cam has a warped surface and is bodily displaced to present different cam tracks.
