Kind Code:
A1
Abstract:
Provided is an opening/closing, lifting/lowering device for a water gate, capable of automated opening/closing and lifting/lowering of a water gate using a small drive device and capable of being installed at a low cost. The opening/closing, lifting/lowering device for a water gate comprises a deceleration mechanism (12) for lifting/lowering, such that the water gate (11) can be manually lifted, lowered, opened or closed using a handle (15) detachable from an input shaft (13), and has: an extendable input shaft (20) provided in a shaft coupling section (13a) for the input shaft having the detachable handle (15), so as to be coupled and extended in series via a joint section (20a); a bearing section (21) for the extendable input shaft (20) that bears the extendable input shaft; a casing (22) fixed to a housing (12a) for the deceleration mechanism for lifting/lowering so as to support the bearing section (21) of the extendable input shaft and cover the extendable input shaft (20); and a dynamic force deceleration device (30) provided as a dynamic force source that rotates the extendable input shaft (20), configured by an electric motor (31) and a deceleration mechanism (32) for the dynamic force source that receives the dynamic force of the electric motor and transmits a deceleration dynamic force to the extendable input shaft (20), and contained within the casing (22).
