PROBLEM TO BE SOLVED: To eliminate some defects that a conventional type hydraulic generating device utilizing river water flow was a device used at a water flow of deep water depth, a screw installing work was troublesome and when an amount of river water was increased in typhoon season, it was necessary to remove a power generating device installed at water surface or immersed in water becoming trouble in flowing river water.SOLUTION: In order to solve the aforesaid theme, the hydraulic generating device of this invention is constituted that a rotating shaft of a power generator main body installed out of a water flow and a screw immersed in the water flow are connected by a universal joint. The extremity end of a screw shaft can be oscillated around the universal joint, resulting in that the screw shaft faces toward a direction of water flow to cause the power generating device to be easily installed. In the case that the power generating device is installed at the river bottom part, the power generating device of this invention is installed at a power generating trench and a concavity of the power generator not to hinder against the river water flow. |
