FOUR-DIMENSIONALLY DRIVING INJECTION DEVICE

摘要

PURPOSE: A multi-shaft time-varying driving injection system is provided to make the directions of an injection nozzle be freely changed in all directions to implement various three dimensional shapes of a water stream, thereby presenting fantastic water shows. CONSTITUTION: A multi-shaft time-varying driving injection system includes a first rotating unit, a second rotating unit and a third rotating unit. The first rotating unit rotates a first vertical tube(10) and a part of the first vertical tube. The second rotating unit rotates a second vertical tube(20) and a part of the second vertical tube rotating around the first vertical as a center by the first rotating unit. The third rotating unit rotates a horizontal tube(30) and a part of the horizontal tube rotating around the first vertical tube or the second vertical tube as a center by at least one between the first rotating unit and the second rotating unit.
