The piles 1 2 and piles 2 3 are connected by a cross bar 21. The cross bars 21 are fixedly connected to the piles 1 2 and piles 2 3. The lifter 211 is fixedly connected to the top of the cross bar 21. The lifter 211 is located in the middle of the cross bar 21. The inner side of the lifter 211 is provided with a threaded rod 22. The position of the threaded rod 22 can be raised or lowered by the lifter 211. The threaded rod 22 passes through the cross bar 21. The bottom of the threaded rod 22 is located below the cross bar 21, and the threaded rod 22 is fixed to the top of the cross bar 21. The bottom of 22 is provided with a gate plate 4. When the threaded rod 22 rises or falls, the gate plate 4 will also rise or fall synchronously, so that the height of the gate plate 4 can be controlled by the lifter 211. The gate plate 4 is provided with a clearance groove 42 on both sides. The clearance groove 42 is parallel to the pile 1 2 and the pile 2 3. The inner side of the clearance groove 42 is connected with a movable plate 43 through a plurality of springs 421. The plurality of springs 421 are arranged equidistantly, and the two ends of the spring 421 are fixedly connected to the gate plate 4 and the movable plate 43 respectively. The movable plate 43 is slidably connected to the clearance groove 42. A triangular water stop 431 is provided on the side of the movable plate 43 away from the spring 421. The triangular water stop 431 is fixedly connected to the movable plate 43. The movable plate 43 and the triangular water stop 431 can be squeezed by the spring 421 to squeeze the pile. The inner side of the first pile 2 and both sides of the pile 2 3 are provided with a connecting groove 31, the size of the connecting groove 31 is smaller than the triangular water stop strip 431, and the position of the fixing plate 1 32 corresponds to the position of the triangular water stop strip 431, and the triangular water stop strip 431 is movably connected to the connecting groove 31. When the triangular water stop strip 431 enters the inner side of the connecting groove 31, since the size of the triangular water stop strip 431 is larger than the connecting groove 31, the triangular water stop strip 431 will be stuck on the outer side of the connecting groove 31, and the spring 421 will make the connection between the triangular water stop strip 431 and the connecting groove 31 tighter, thereby achieving the purpose of water stopping. Two slide grooves 45 are respectively provided on both sides of the gate plate 4, and two fixed plates 32 are provided on the inner side of the pile 1 2 and both sides of the pile 2 3. The thickness of the fixed plate 1 32 is the same as that of the slide groove 4 5, a fixing plate 2 33 is provided on the top of the fixing plate 1 32, and the thickness of the fixing plate 2 33 is the same as that of the fixing plate 1 32, and a bevel is provided on the bottom of the fixing plate 2 33, and the fixing plate 1 32 is located on the inner side of the slide groove 45. When the gate plate 4 moves upward, the fixing plate 2 33 will enter the inner side of the slide groove 45. Therefore, in the process of the gate plate 4 moving up and down, the fixing plate 1 32 and the fixing plate 2 33 will be located on the inner side of the slide groove 45 in sequence. The size of the fixing plate 2 33 is larger than that of the fixing plate 1 32, and the width of the fixing plate 2 33 is larger than that of the fixing plate 1 32. A connecting rod 44 is provided on the top of the movable plate 43, and the connecting rod 44 moves synchronously with the movable plate 43. When the movable plate 43 slides on the inner side of the give way groove 42, the fixed seat 432 will also move synchronously.The two ends of the connecting rod 44 are respectively located above the two slide grooves 45. When the gate plate 4 contacts the top of the base 1, the gate plate 4 is located at the bottom of the pile 1 2 and the pile 2 3, and the fixed plate 1 32 is located on the inner side of the slide groove 45. Since the width of the fixed plate 1 32 is narrow, under the action of the spring 421, the movable plate 43, the triangular water stop strip 431 and the connecting rod 44 will move toward the position of the connecting groove 31, and the triangular water stop strip 431 will enter the inner side of the connecting groove 31, thereby achieving the purpose of water stopping. When the gate plate 4 slides upward, the fixed plate 2 33 will gradually be located on the inner side of the slide groove 45. Since the width of the fixed plate 2 33 is wide, during the rising process of the gate plate 4, the fixed plate 2 33 will connect The connecting rod 44 is pushed away from the connecting groove 31, so that the movable plate 43 and the triangular water stop strip 431 are retracted to the inner side of the clearance groove 42. This can prevent the triangular water stop strip 431 from generating friction with the pile 1 2 or the pile 2 3 during the rising and falling process of the gate plate 4, which may cause the triangular water stop strip 431 to be damaged and affect the water-stopping effect of the triangular water stop strip 431. At the same time, because the triangular water stop strip 431 moves with the gate plate 4, when the gate plate 4 moves upward to allow water to flow through, the water will not contact the triangular water stop strip 431, thereby preventing the mud and sand in the water from contacting the triangular water stop strip 431 and causing damage to the triangular water stop strip 431, which is beneficial to improving the service life of the triangular water stop strip 431.
[0022] Two piles 2 are located at both ends of the base 1, and several piles 2 3 are located between the two piles 1, and the distance between the several piles 2 3 and the distance between piles 1 2 and piles 2 3 are the same; piles 1 2 and piles 2 3 are both fixedly connected to the base 1, and several gate plates 4 are located between the several piles 2 3 and pile 1 2.
[0023] The crossbar 21 is parallel to the base 1 , and the width of the gate plate 4 matches the length of the crossbar 21 ; the gate plate 4 is located below the crossbar 21 , and the top and bottom of the gate plate 4 are always parallel to the crossbar 21 .
[0024] The give way groove 42 is located between the two slide grooves 45 and is not connected to the slide groove 45; the give way groove 42 and the fixed plate 2 33 are staggered with each other, so the fixed plate 2 33 and the fixed plate 1 32 will not interfere with the movable plate 43.
[0025] A connecting seat 41 is provided at the top of the gate 4, and the bottom of the threaded rod 22 is rotatably connected to the connecting seat 41; through the rotatable connection between the connecting seat 41 and the threaded rod 22, the gate 4 is always in a translation state, preventing the gate 4 from being affected by the rotation of the threaded rod 22.
[0026] A fixed seat 432 is provided on the top of the movable plate 43 , and the connecting rod 44 is rotatably connected to the inner side of the fixed seat 432 ; the fixed seat 432 is fixedly connected to the movable plate 43 , and the connecting rod 44 and the movable plate 43 can move synchronously through the fixed seat 432 .
[0027] Two limiting rings 441 are fixedly connected to the outer side of the connecting rod 44, and the two limiting rings 441 are respectively located on both sides of the fixing seat 432; the two limiting rings 441 can avoid displacement between the connecting rod 44 and the fixing seat 432, resulting in the situation where the position of the connecting rod 44 and the sliding groove 45 do not correspond.
[0028] The working principle and use process of the present invention are as follows: when in use, the height of the gate plate 4 can be controlled by the lifter 211. When the gate plate 4 contacts the top of the base 1, the gate plate 4 is located at the bottom of the pile 1 2 and the pile 2 3, and the fixed plate 1 32 is located on the inner side of the slide groove 45. Since the width of the fixed plate 1 32 is narrow, under the action of the spring 421, the movable plate 43, the triangular water stop 431 and the connecting rod 44 will move to the position of the connecting groove 31, and the triangular water stop 431 will enter the inner side of the connecting groove 31. Due to the size of the triangular water stop 431, the movable plate 43, the triangular water stop 431 and the connecting rod 44 will move to the position of the connecting groove 31. The inch is larger than the connecting groove 31, therefore, the triangular water stop strip 431 will be stuck on the outside of the connecting groove 31, and the spring 421 will make the connection between the triangular water stop strip 431 and the connecting groove 31 tighter, thereby achieving the purpose of stopping water. When the gate plate 4 slides upward, the fixed plate 2 33 will gradually be located on the inner side of the slide groove 45. Since the width of the fixed plate 2 33 is wider, during the rising process of the gate plate 4, the fixed plate 2 33 will push the connecting rod 44 away from the connecting groove 31, thereby causing the movable plate 43 and the triangular water stop strip 431 to shrink to the inner side of the give way groove 42.
