[0031] A sliding groove 13 is formed through the middle of one set of support rods 12, a movable rod 14 is formed through the top of one set of support rods 12 and is slidably connected, and the movable rod 14 passes through one side of the support rod 12 and is fixedly connected to the baffle 2, a U-shaped rod 15 is fixedly connected to one side of the two sets of movable rods 14, and the U-shaped rod 15 slides in the sliding groove 13, and a resistance groove 16 is formed in the middle of the bottom of the U-shaped rod 15, and the resistance groove 16 cooperates with the resistance rod 11;

[0032] A set of movable rods 14 are provided with arc grooves 17 at both ends of one side, two compression grooves 18 are penetrated and provided on both sides of one side of the movable rod 14, a spring 19 is provided on the relatively close side of the two compression grooves 18, a rotating rod 20 is fixedly connected to the top of the relatively far side of the two compression grooves 18, the outer walls of the two rotating rods 20 are rotatably connected to movable blocks 21, and the movable blocks 21 are fixedly connected to the spring 19, and a recovery rod 22 is fixedly connected to one side of the two movable blocks 21, and the recovery rod 22 slides in the arc groove 17;

[0034] The above scheme is adopted: when the water level intercepted by the baffle 2 is high, the floating plate 4 will change according to the height of the water flow and always float to the surface of the water. When the floating plate 4 rises, it will drive the connecting plate 5 and the output rod 6 to slide upward on the surface of the baffle 2.

[0038] An L-shaped rotating plate 10 is fixedly connected to the bottom of the baffle 2, and the L-shaped rotating plate 10 passes through the hinge seat 25 and is rotatably connected;

[0039] A sealing groove 30 is provided on one side of the L-shaped rotating plate 10 away from the baffle 2, which can be sealed when the baffle 2 rotates;

[0043] The above scheme is adopted: when the floating plate 4 rises, it will drive the connecting plate 5 and the output rod 6 to slide upward on the surface of the baffle plate 2, and the upward sliding of the output rod 6 will drive the L-shaped connecting rod 7 to slide upward. When the L-shaped connecting rod 7 slides upward, the resistance rod 11 will also slide upward. At this time, the resistance rod 11 will resist the resistance groove 16 and drive the U-shaped rod 15 to slide upward. When the U-shaped rod 15 moves upward, it will drive the movable rod 14 to slide upward. When the movable rod 14 pushes the baffle plate 2 to rotate, the baffle plate 2 will drive the L-shaped rotating plate 10 to rotate in the mounting groove 24 through the hinge seat 25. When the baffle plate 2 drives the L-shaped rotating plate 10 to rotate, the sealing gasket 29 will contact the sealing groove 30 for sealing, so as to prevent water from flowing out through the mounting groove 24 and affecting the sealing effect. The elastic force of the spring 27 makes the limit plate 28 and the sealing gasket 29 always resist in the sealing groove 30.

[0044] The working principle and use process of the present invention:

[0045] When the device is needed, it is placed at a location where flood prevention is needed. The steel cone 31 is inserted into the ground to make the device more stable when in use. When the water level intercepted by the baffle 2 is high, the floating plate 4 will change according to the height of the water flow and always float to the surface of the water. When the floating plate 4 rises, it will drive the connecting plate 5 and the output rod 6 to slide upward on the surface of the baffle 2. The upward sliding of the output rod 6 will drive the L-shaped connecting rod 7 to slide upward. When the L-shaped connecting rod 7 slides upward, it will drive the resistance rod 11 to slide upward. At this time, the resistance rod 11 will resist upward in the resistance groove 16 and drive the U-shaped rod 15 to slide upward. When the U-shaped rod 15 moves upward, the U-shaped rod 15 will slide upward. When the movable rod 14 moves upward, it will drive the movable rod 14 to slide upward, and when the movable rod 14 slides upward, it will push the baffle 2 to move forward to adjust the angle of the baffle 2. When the movable rod 14 is pushed by the U-shaped rod 15 to slide in the support rod 12, the movable blocks 21 on both sides of the bottom of the movable rod 14 will be squeezed to compress the spring 19. At this time, the movable block 21 will be stored in the compression groove 18. When the movable rod 14 stops moving, the movable block 21 will be reset by the elastic force of the spring 19. At this time, the movable block 21 will be stuck in the card slot 23 to limit the movable rod 14, and the baffle 2 is supported by the movable rod 14;

[0046] When the movable rod 14 pushes the baffle plate 2 to rotate, the baffle plate 2 will drive the L-shaped rotating plate 10 to rotate in the installation groove 24 through the hinge seat 25. When the baffle plate 2 drives the L-shaped rotating plate 10 to rotate, the sealing gasket 29 will contact with the sealing groove 30 for sealing, so as to prevent water from flowing out through the installation groove 24 and affecting the sealing effect. The elastic force of the spring 27 makes the limit plate 28 and the sealing gasket 29 always contact with the sealing groove 30.

[0047] When flood prevention is not needed, the two recovery rods 22 are pinched and brought close to each other, and the two recovery rods 22 slide in the arc groove 17. When the two recovery rods 22 are pinched and brought close to each other, the movable block 21 is retracted into the compression groove 18 through the recovery rod 22, and the spring 19 is compressed at the same time, so that the movable block 21 is disengaged from the slot 23, and the limit state is released. Then, the recovery rod 22 is pinched and pressed downward to make the movable rod 14 slide downward for reset, and the movement of the movable rod 14 can drive the baffle 2 to reset.
