Both ends of each transmission chain are fixedly connected to a gate assembly and are in transmission connection with a set of transmission components. Each set of transmission components is arranged on the same side of the transmission chain that is in transmission connection with it. This invention does not require building a dam for water storage and power generation. The water conservancy power generation device of this invention is directly arranged in the water flow or on the shore. By sequentially blocking the water flow with each gate at the lowest vertical height, a continuous thrust is generated to drive the turntable assembly to rotate. The rotation of the turntable assembly drives the mechanical energy output shaft to rotate, and after increasing the speed through the speed change gearbox, it drives the generator to rotate to achieve power generation.

The movement of the T-shaped plate (47) toward the end away from the connecting plate (43) will drive the slide plate (45) to move toward the end away from the connecting plate (43); Step 4: When the slide plate (45) leaves the range of the connecting plate (43), the connecting plate (43) will move downward, and the downward movement of the connecting plate (43) will drive the filter box (44) to move downward to cope with the situation of low water flow. When the water flow is high, the connecting plate (43) will be manually pushed to move upward; Step 5: The connection plate (43) moves upward to contact and squeeze the slide plate (45) to move toward the end away from the connection plate (43). When the connection plate (43) leaves the range of the slide plate (45), the slide plate (45) returns to the initial state under the action of spring 1 (46) without being squeezed.
