Embodiment 1
[0032] refer to Figure 1-Figure 2 , an emergency automatic sealing device for the inlet hole of the flow channel of a hydropower station unit, comprising an outer corridor 1, an inlet hole 2, a water collection tank 3, an air supply pipe 10 and an electric wire 9, and the rear end of the outer corridor 1 is processed with an inlet circle The hole 2 and the outer corridor 1 are processed with a water collection tank 3. The design of the water collection tank 3 prevents normal water leakage from causing a small amount of water on the ground and falsely starting the device. The inner left wall of the outer corridor 1 is equipped with an air supply pipe 10 and electric wires through cable ties. 9. The design of the gas supply pipe 10 facilitates the delivery of gas to the inside of the plugging air bag 4, the design of the electric wire 9 facilitates the power supply to the normally closed solenoid valve control gas valve 6 and the liquid level controller 7, and the inner bottom o...
Embodiment 2
[0035] refer to Figure 3-Figure 6 , an emergency automatic plugging device for the flow passage of a hydropower station unit, which also includes a moving rod 13 and a rotating rod. Two springs 14 are symmetrically installed on the bottom of the sump 3 through screws, and the top of the spring 14 is welded with a moving rod 13. The moving rod 13 is slidably installed inside the sump 3. The design of the moving rod 13 facilitates the cleaning of the sundries inside the sump 3. The design of the spring 14 facilitates the movement and reset of the moving rod 13. On the front wall of the sump 3, A storage tank is processed, and a moving block 15 is movable inside the storage tank, and the rear end of the moving block 15 extends to the inside of the sump 3 and fits with the bottom end of the moving rod 13. This design facilitates the movement of the moving block 15 to drive the moving rod 13 to move. A T-shaped round block 16 is movably installed at the inner bottom of the outer c...
