Claim:
A hydroelectric device, comprising two base members, a hoist member, a paddle wheel member, and a power generation member; wherein the base members are for the installation of the hoist member, the paddle wheel member, and the power generation member; an accommodation space is formed between the base members; two pivotal elements are configured on the base members, respectively; the host member comprises a pair of arm elements and a connection rod; each arm element has a first end joined to one of the pivotal elements with a shaft so that the two arm elements are connected to the base members, and are able to swivel with the shafts as pivots; the connection rod is configured between and perpendicularly connected to the arm elements so that the arm elements swivel synchronously; the paddle wheel member comprises an axle whose two ends are pin-joined to the arm elements' second ends, respectively, a plurality of paddles radially configured around the axle, and a first transmission element configured at an end of the axle spinning synchronously along with the axle; the axle is rotatably configured across the arm elements, and across the base members, and each paddle is capable of being submerged at least partially into a water stream; the water stream pushes the paddles to turn the axle; each paddle has an outer end configured into a roughly V-shaped bended section; and the power generation member comprises a second transmission element at an input end engaged by the first transmission element of the axle; when the axle is turned and the first transmission element spins synchronously, the second transmission element of the power generation member is engaged to spin synchronously; and the power generation member is driven to produce electricity.
