the liquid water forms a wave-like flowing direction in the containing frame 10, and accordingly the lifting float 27 and the turning rod 25 perform a lifting motion around the hinge point, thereby causing the first crank 241 and the second crank 242 to perform a lifting motion, when the first crank 241 and the second crank 242 perform the lifting motion, the first crank 241 performs a swinging motion through the first annular body 243, the first annular body 243 performs a pulling motion on the first push plate 246 through the first pulling rod 244 and the first movable rod 245, simultaneously the first annular body 243 performs a pulling motion on the first push plate 246 through the second pulling rod 247, when the first annular body 243 performs a counterclockwise rotation, the first push plate 246 is fixedly clamped through the barbed groove structure 230, that is, the first movable rod 245 performs a pulling motion on the first push plate 246 in a counterclockwise direction, and simultaneously the second pulling rod 247 performs a pulling motion on the first push plate 246 at the bottom in the barbed groove structure 230 The first ratchet wheel is driven to rotate, so that the subsequent power generation effect is realized; in addition, when the first annular body 243 rotates clockwise, the barbed sheet groove structure 230 does not engage and fix the first pushing plate 246, the first movable rod 245 pulls the first pushing plate 246 clockwise, and the second pulling rod 247 drives the first pushing plate 246 to rotate downward at the bottom;

in addition, when the first annular body 243 moves counterclockwise, the second annular body 240 moves clockwise, and when the second annular body 240 rotates counterclockwise, the second push plate 2430 is fastened and fixed through the barbed sheet groove structure 230, that is, the second movable rod 2420 pulls the second push plate 2430 in the counterclockwise direction, and meanwhile, the fourth pull rod 2440 drives the second barbed wheel to rotate in the barbed sheet groove structure 230 for the second push plate 2430 at the bottom, thereby realizing the subsequent power generation effect; in addition, when the second annular body 240 rotates clockwise, the barbed sheet groove structure 230 does not engage and fix the second pushing plate 2430, the second movable rod 2420 pulls the second pushing plate 2430 clockwise, and the fourth pulling rod 2440 drives the second pushing plate 2430 to rotate downward at the bottom.

Just can realize the rotation effect to driving wheel and dwang through the cooperation relation of parts such as first crank and second crank to because the inclined plane structure of thorn piece groove structure, it can realize one-way drive mode, just can drive first thorn wheel under anticlockwise circumstances promptly and rotate the drive, and can not make first thorn wheel rotate because the inclined plane structure under clockwise circumstances. Meanwhile, the two groups of driving rods are symmetrically arranged in position relation, namely the third crank and the fourth crank form different driving tenses with the first crank and the second crank, the third crank rotates anticlockwise when the first crank rotates clockwise, and the third crank rotates clockwise when the first crank rotates anticlockwise. Meanwhile, the second pushing plate can drive the second ratchet wheel to rotate and drive under the condition of anticlockwise, and the second ratchet wheel cannot rotate under the condition of clockwise due to the inclined surface structure, but the first crank and the second crank are opposite in rotation mode, so that the driving action on the driving wheel can be alternately realized, namely the second pushing plate does not drive the second ratchet wheel when the first pushing plate drives the first ratchet wheel, and the second pushing plate drives the second ratchet wheel when the second pushing plate does not drive the first ratchet wheel, so that the alternate driving is realized, the continuous power generation process is realized, and the basic principle of how to realize the continuous power generation of water flow by students forms an intuitive impression.
