PURPOSE: A manual hydraulic generator for hydraulic lifting or rotating floodgates is provided to facilitate the long-term and stable use by manually ascending or descending floodgates in case of emergency. CONSTITUTION: A manual hydraulic generator for hydraulic lifting or rotating floodgates comprises a fixing board(310), a rotary shaft, a manual hydraulic pump(330), and gears(345,355). The fixing board is vertically installed on the single body of the hydraulic generator which has an oil tank. The rotary shaft is combined with the front side of the fixing board and is rotated by the rotation of a handle. The manual hydraulic pump is fixed so that the rotary shaft can protrude from the rear side of the fixing board, and has an intake pipe for receiving oil and a discharge pipe for supplying hydraulic power. The gears are installed on the rotary shafts of the handle and manual hydraulic pump for operating the manual hydraulic pump by interlocking with each other in order to deliver the rotation power of the handle to the rotary shaft of the manual hydraulic pump. |
