Installation structure of rapid gate of water diversion pipe of hydraulic turbine set

The installation structure comprises an installation frame, an inner cavity is formed in the installation frame, a water passing opening communicated with the inner cavity is formed in the installation frame in a penetrating mode, a gate is connected into the inner cavity in a sliding mode, and a guide rolling wheel abutting against the inner wall of the inner cavity is installed on the gate. And a driving piece for driving the gate to move up and down is installed in the inner cavity, a flow guide groove is formed in the bottom of the gate, and a flow guide protection plate is rotationally connected into the flow guide groove. When the gate is opened, the sealing air bag can be stored and protected, the flow guide protection plate is inclined, the gate is protected, the service life of the gate is prolonged, when the gate is closed, the flow guide plate protection plate is vertical, the sealing air bag is expanded, the sealing performance of the gate is guaranteed, in addition, impurities in the inner cavity
