The invention discloses a conveying pipeline for water conservancy irrigation. The conveying pipeline comprises a valve body, a sealing device is arranged in the valve body, a water inlet pipe is arranged at one side of the valve body, a connecting block is arranged at the other side of the valve body, and a connecting pipe is arranged at one side, near the valve body, of the connecting block, and is connected to the inside of the valve body; a first protection box internally provided with an air cylinder is arranged on the connecting block, the connecting block is internally provided with a cavity, a piston rod of the air cylinder penetrates through the side walls of the first protection box and the connecting block in sequence and extends into the cavity, a closing block is fixed to the tail end of the piston rod of the air cylinder, a fixing box is connected to one side, far from the valve body, of the connecting block, and a second protection box is arranged at one side of the fixing box. In the conveying pipeline for the water conservancy irrigation, the electricity generation function is achieved through the combination of hydroelectric equipment, the water volume can be automatically adjusted through the combination of the air cylinder and the closing block, not only is the irrigation convenient, but also electricity generation can be conducted, and the conveying pipeline corresponds to the idea of sustainable development, and suitable for popularization.
