Imitated pirate ship type hydroelectric power generation device

An imitated pirate ship type hydroelectric power generation device, filled with a working fluid (WF) therein, the imitated pirate ship type hydroelectric power generation device comprising:

• a long box body (10), comprising an accommodating cavity (11) providing the working fluid (WF) to be filled;
• a hydro-turbine power generator unit (20), comprising an impeller (22) and a power generator (21) coupled to the impeller (22), and the impeller (22) installed in the accommodating cavity (11);
• a pivot structure (30), installed on the long box body (10) and located at a middle portion of the long box body (10);
• and
• a connecting structure (40), coupled to the pivot structure (30) and the long box body (10);
• wherein, after a force is applied to the long box body (10), the long box body (10) swings pivotally by the pivot structure (30) as a rotation center, and the working fluid (WF) flows reciprocally in the accommodating cavity (11) and drive the impeller (22) to rotate to generate an electric power from the power generator (21).
