The invention discloses a drainage power generation device. The drainage power generation device comprises a first rotating pipe, a second rotating pipe, a first generator and a second generator, wherein the first rotating pipe consists of a water inlet section and a water outlet section communicated with each other; a spiral blade is fixed at the inner side of the water inlet section near the water outlet section; the water outlet section is a diffusion pipe; the second rotating pipe consists of an expansion section and a conventional section communicated with each other; the expansion section expands to form an accommodating cavity; the water outlet section is accommodated in the accommodating cavity; a blade is arranged at the inner side of the expansion section opposite to the edge of a water outlet of the water outlet section; the first generator is connected with the first rotating pipe through a first power transmission device; and the second generator is connected with the second rotating pipe through a second power transmission device. The drainage power generation device is simple in structure; and as the gravitational potential energy of water currents is converted to kinetic energy, when the first rotating pipe and the second rotating pipe rotate, the first power transmission device and the second power transmission device drive the first generator and the second generator to rotate for electricity generation. The drainage power generation device can be applied to the high-rise waste water power generation. |
