Abstract

PURPOSE: To prevent damage to pripheral parts caused by a fracture of the safety pin by obtaining the pin such that its fracture has a smooth face when broken.
CONSTITUTION: The opening-shutting structure of the guide vane of the pump water-wheel is provided with the safety pin 6 in the overlap of both the guide vane arm 2 fixed to the guide vane 1 and the link 3 attached to the guide ring 4 which drives the guide vane, the pin 6 is broken in order to prevent damage to other parts when an excessive force is applied to the guide vane 1 by a foreign substance. The portion of the pin 6 which is put in the hole 7 of the link 3 is made the driving side cylinder 8 of height H and the portion put in the hole 9 of the arm 2 is made the driven side cylinder 10, the weak point 12 of a loop groove of diameter D is provided to the boundary between both the cylinders 8, 10, and a hole 13 of diameter d is formed in the weak point so that respective dimensions H, D and d satisfy the formula.
