[0027] Embodiment 1:

[0028] The electronically controlled water inlet gate of a hydropower station provided by the utility model is preferably implemented as follows Figures 1 to 7 As shown: an electrically controlled water inlet gate of a hydropower station, comprising a frame 1 and a gate 2, a gate 3 is provided at the bottom of the frame 1, a contraction groove 4 is provided at the top of the inner wall of the gate 3, the gate 2 is inserted into the contraction groove 4, and an electrically controlled switch gate mechanism 5 is provided between the gate 2 and the frame 1;

[0029] The electric control switch gate mechanism 5 includes a top box 501 and a traction rope 505. The top box 501 is fixedly installed on the top of the frame 1. A motor 502 is fixedly installed on the inner wall of the top box 501. A long rotating shaft 503 is fixedly installed on the output end of the motor 502. One end of the long rotating shaft 503 is rotatably connected to the inner wall of the top box 501 through a bearing. A winding wheel 504 is fixedly sleeved on the outer wall of the long rotating shaft 503. One end of the traction rope 505 is fixedly installed on the inner wall of the winding wheel 504. A through hole 513 is opened on the top of the frame 1. The other end of the traction rope 505 passes through the through hole 513 and is fixedly installed on the top of the gate 2. The gate 2 A fixed block 506 is fixedly installed at the top, a slide groove 510 is opened at the top of the inner wall of the contraction groove 4, and a moving block 508 is slidably connected to the inner wall of the slide groove 510. A slide rod 509 is fixedly installed on the inner wall of the slide groove 510. A rod hole 511 is opened on the moving block 508, and the slide rod 509 movably passes through the moving block 508 through the rod hole 511. A spring 512 is surrounded by the outer wall of the slide rod 509, one end of the spring 512 is fixedly installed on the left side of the moving block 508, and the other end of the spring 512 is fixedly installed on the inner wall of the slide groove 510, and the moving block 508 and the fixed block 506 support are hinged with a folding plate 507.

[0030] Specifically, the above technical solution is as follows: the motor 502 is started through the control panel 8, the motor 502 drives the long rotating shaft 503 to rotate, the long rotating shaft 503 drives the winding wheel 504 to rotate, the winding wheel 504 drives the traction rope 505 to move upward, the traction rope 505 drives the gate 2 to move upward quickly, so as to open the gate 3, when the gate 2 moves upward, it drives the fixed block 506 to move upward, the fixed block 506 drives the folding plate 507 to rotate, and the folding plate 507 drives the moving block 508 to move to the outside of the slide slot 510, so that the moving block 508 compresses the spring 512, and when it is necessary to close the gate 3, the motor 502 is started to reverse, the traction rope 505 is released downward, and the moving block 508 is compressed. Block 508 will move toward the inside of the slide groove 510 under the restoring force of the spring 512, and the moving block 508 drives the folding plate 507 to rotate, and the folding plate 507 drives the gate 2 to move downward through the fixed block 506, so that the gate 2 can quickly close the gate 3 under the joint action of its own gravity. Through this mechanism, the gate 3 can be opened and closed quickly to meet the operational needs in emergency situations, and the problem that most of the existing water intake gates 2 of hydropower stations are used to lift the gate 2 and switch operations by hand-cranked winch opening and closing machines, which leads to reliance on manual labor, low efficiency and excessive manpower consumption, and cannot meet the operational needs of fast opening and closing of the gate 2 in emergency situations.
