The invention discloses a shaft through-flow turbine provided with a tidal current energy rotating wheel. The shaft through-flow turbine comprises a rinsing runner. A concrete shaft, a through-flow rotating wheel movable guide vane, a through-flow wheel and at least two tidal current energy rotating wheels b are successively arranged on the center axis of the rinsing runner along the water flow direction; generators b are connected to main shafts of the tidal current energy rotating wheels b, at least two tidal current energy rotating wheels a are symmetrically arranged on opposite two sides of the concrete shaft, separately, generators a are connected to main shafts of the tidal current energy rotating wheels a, and generators c are connected to the through-flow rotating wheel movable guide vane and the main shaft of the through-flow wheel. The investment on civil engineering of a power station can be reduced, the generating capacity of the power station can be increased, and the operating stability of the power station can be improved.
Description
technical field [0001] The invention belongs to the technical field of tidal power generation, and relates to a shaft tubular water turbine arranged with a tidal current energy runner. Background technique [0002] As the focus of my country's water conservancy development has gradually shifted from high water head to medium and low water head, the traditional axial flow turbine has the problems of low energy index and large investment in civil engineering and equipment under the conditions of low water head and large flow. The hydraulic turbine, which has good operation effect under the condition of low water head, has been widely developed and applied. Tubular turbines can be mainly divided into bulb tubular turbines, shaft extension tubular turbines and shaft tubular turbines. Among them, the bulb tubular turbine has relatively high cost due to problems in design, installation, operation and maintenance. The curved flow channel of the shaft-extension tubular turbine and ...
