Abstract
The utility model provides a novel axial-flow turbine. The novel axial-flow turbine comprises a runner, a guide vane, a main shaft and a volute connected with a water inlet pipe, wherein the volute is made of a steel plate in a welded mode. The novel axial-flow turbine further comprises a water guide mechanism made of a steel plate. A front-end shell of the water guide mechanism is connected with the volute in a welded mode. A speed control mechanism is installed at the upper end of the water guide mechanism. A water inlet valve is arranged on a water inlet of the volute. The other end of the water inlet pipe is connected with a pressure pool. A filter screen is arranged at a water outlet of the pressure pool. The far end of the water inlet pipe is connected with the pressure pool. Water in the pressure pool is deep, so that it is guaranteed that the pressure of water entering the runner is basically constant, and therefore electricity generation efficiency is improved; the volute and the water guide mechanism are both made of steel plates and are welded and fixed to each other, so that the stability of the novel axial-flow turbine is guaranteed, and the novel axial-flow turbine is not prone to influence of vibration; the speed control mechanism guarantees the stability of the novel axial-flow turbine to a certain extent; the water inlet pipe is fixed through an anti-skidding pier, so that displacement of the water inlet pipe is avoided.
