Abstract:
A weir having an integrated gate mechanism, pertaining to the field of hydraulic engineering facilities. The weir comprises a gate member (1) installed between gate walls (5). The gate member (1) and the gate walls (5) form a sealed structure for preventing leaks at the sides thereof by means of installing side rubber sealing members on left and right sides of the gate member. A bottom rubber sealing member (10) is installed between a bottom portion of the gate member (1) and a bottom threshold (4) to form a sealed structure for preventing leaks at the bottom portion. Multiple support hinge bases (2) are fixed to the bottom threshold (4). The bottom portion of the gate member (1) is hinge connected to front ends of the support hinge bases (2) via front hinge pins (7). The gate member (1) is provided with a hydraulic cylinder (3) on the side away from water. One end of the hydraulic cylinder (3) is hinge connected to a rear surface of the gate member (1) via an upper hinge pin (11), and another end of the hydraulic cylinder (3) is hinge connected to a rear end of the support hinge bases (2) via a rear hinge pin (6). The weir having the integrated gate mechanism is low cost, easily managed and applicable to all types of river courses, especially in wider river courses, and has a superior price–performance ratio.
