A turbine structure for a tidal power plant is provided to circulate the water in a lake and to generate electricity using seawater entering and leaving a channel and to utilize as easily approchable resources for marine tourism by forming a hydro-turbine generator chamber, a machine room and an air-conditioning system in an integral system and unifying with an approach road. The turbine structure for a tidal power plant includes a base course(2) constructed on the seabed rock surface(1) to form a foundation, a hydro-turbine generator(10) placed on the base course, a draft tube(16) formed to discharge seawater(W) from the hydro-turbine generator to a lake(L), a passage(62) having a moisture condensation trench and a maintenance passage(63) formed on a lower space(65) of the base course, and an outlet(60) installed to a part which is easily approchable from the maintenance passage to discharge the moisture condensation and leaking water generated in the passage and the maintenance passage through a drainpipe(61). The hydro-turbine generator generates electricity when seawater flows in the lake from the seawater side by placing a front head toward the seawater side and a runner(18) toward the lake side and has an opening of a curve structure(R) to prevent the vortex generation of seawater and aeration and a venturi structure which is narrow to the runner of the hydro-turbine generator and wide to the discharge unit of the lake. In addition, a hydro-turbine generator chamber(21) connected to an approach passage(40) for managing a hydro-turbine generator is installed on the upper part of the hydro-turbine generator, a machine room(22) is installed adjacently to the hydro-turbine generator chamber, primary and secondary approach roads(33,34) are installed on the back part of the draft tube in a multi-layer structure, and stop log support channels(12,17) are installed on two ends of the turbine structure to install stop logs using gantry cranes(27,35). |
