[0024] In order to enable the two buffer baffles 5 to rotate simultaneously, and the two buffer baffles 5 rotate in opposite directions, the top surface and the bottom surface of the inner wall of the fixed plate 6 are connected to a connecting shaft 9 by a common bearing, and a driving spur gear 10 is fixedly sleeved on the middle part of the surface of the connecting shaft 9, and a driven spur gear 11 is fixedly sleeved on the upper end of the surface of the right rotating shaft 7, and the driving spur gear 10 and the driven spur gear 11 are meshed with each other, and a driving sprocket 12 is fixedly connected to the upper end of the surface of the left rotating shaft 7, and a driven sprocket 13 is fixedly sleeved on the lower end of the surface of the connecting shaft 9, and a transmission chain 14 is commonly sleeved on the surfaces of the driving sprocket 12 and the driven sprocket 13, and the driving sprocket 12 and the driven sprocket 13 are transmission connected through the transmission chain 14.

[0025] In order to enable the gate plate 2 to move up and down, thereby opening the gate to release water, support plates 15 are fixedly connected to the left and right sides of the top surface of the gate pier 1, and the top surfaces of the two support plates 15 are commonly fixedly connected to a top plate 16. The middle part of the bottom surface of the top plate 16 is fixedly connected to a first electric telescopic rod 17, and the lower end of the first electric telescopic rod 17 is fixedly connected to the middle part of the top surface of the gate plate 2.

[0026] In order to fix the buffer baffle 5 so that the buffer baffle 5 cannot rotate after the direction is adjusted, thereby improving the stability of the buffer baffle 5, a front positioning hole 18 is opened on the front side of the top surface of each buffer baffle 5, and a rear positioning hole 19 is opened on the rear side of the top surface of each buffer baffle 5.

[0027] In order to protect the support shaft 4 and prevent impurities in the water from damaging the bearing at the bottom of the support shaft 4, a protective cover 24 is fixedly connected to the top surface of the bottom plate 3, and the two support shafts 4 are movably sleeved in the protective cover 24.

[0029] Working principle: First, since the buffer baffle 5 is arranged on the front side of the gate plate 2, the water will first impact the buffer baffle 5, and the two buffer baffles 5 are arranged in an eight-shaped tilt, which will guide the water to flow to both sides, so that only a small part of the water will impact the gate plate 2 from the middle, thereby greatly reducing the impact force of water on the gate plate 2, avoiding the gate plate 2 from being damaged by excessive impact of water. When it is necessary to release water, the first electric telescopic rod 17 is started by the controller 25, and the first electric telescopic rod 17 pulls the gate plate 2 up, thereby opening the gate. The water is released, and then the second electric telescopic rod 20 is started through the controller 25, and the second electric telescopic rod 20 drives the connecting plate 21 to rise, and the connecting plate 21 drives the front positioning rod 22 to rise, so that the front positioning rod 22 is pulled out from the front positioning socket 18, and the buffer baffle 5 is unlocked, and then the motor 8 is started through the controller 25, and the motor 8 drives the left rotating shaft 7 to rotate, and the left rotating shaft 7 drives the driving sprocket 12 to rotate, and the driving sprocket 12 drives the driven sprocket 13 to rotate through the transmission chain 14, and the driven sprocket 13 The connecting shaft 9 is driven to rotate, the connecting shaft 9 drives the active spur gear 10 to rotate, the active spur gear 10 drives the driven spur gear 11 to rotate, the driven spur gear 11 drives the left rotating shaft 7 to rotate, the left and right rotating shafts 7 rotate in opposite directions, the two rotating shafts 7 respectively drive the two buffer baffles 5 to rotate, the buffer baffle 5 on the left rotates 180° clockwise, and the buffer baffle 5 on the right rotates 180° counterclockwise, so that the two buffer baffles 5 become inwardly facing eight-shaped, so that the buffer baffle 5 not only no longer blocks the flow of water, It can also guide water to flow toward the gate plate 2 to speed up the water flow. At this time, the rear positioning socket 19 on the buffer baffle 5 is changed to be set forward, and the second electric telescopic rod 20 is started by the controller 25. The second electric telescopic rod 20 pushes the connecting plate 21 to descend, and the connecting plate 21 drives the rear positioning rod 23 to descend, so that the two rear positioning rods 23 are respectively inserted into the rear positioning sockets 19 on the two buffer baffles 5, so that the buffer baffle 5 can be fixed, the buffer baffle 5 cannot rotate, and the stability of the buffer baffle 5 is improved.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
