STUDY, DESIGN, AND MANUFACTURE OF MECHANICAL ROTATING MECHANISM OF THE PRAYER WHEEL TOWER ON THE TO LICH RIVER OVERFLOW WEIR

Abstract

In its effort to revive the To Lich river, Hanoi has taken many specifc actions, such as dredging, building a weir taking water from the Red River to clean up the To Lich river. The prayer wheel tower is placed on the observation deck on the weir. It has a round, conical shape with a symmetrical, golden painted pattern on black background, and it rotates on its own central line by the flow of water passing through the weir. The transmission structure, which receives energy from the water flow and converts it into the rotational mechanical motion for the tower, was provided by the National Institute of Mechanical Engineering (Narime). The prayer wheel tower and its rotation motion become a symbolic both classic and modern to highlight the landscape of the To Lich weir.
