A connecting belt 20 is provided at the middle position of the two pulleys 24. A second motor 23 is fixed at the position of the top of one of the second threaded rods 17 in the inner cavity of the first slot 18, and the top of one of the second threaded rods 17 is fixed to the output end of the second motor 23. The two ends of the bottom surface of the limiting plate 14 are inclined, and the two second threaded rods 17 can be rotated by starting the second motor 23, so that the limiting plate 14 can move in the vertical direction, so as to be embedded in the mud and sand in the river channel or channel, thereby improving the waterproof effect of the water retaining plate 2, thereby avoiding the situation that water will penetrate into the gap at the bottom of the water retaining plate 2 after long-term use, and improving the stability of the water retaining plate 2 when waterproofing.
[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that the top of the inner warehouse 3 is connected to a rod groove 4, the inside of the rod groove 4 is rotatably connected to a first threaded rod 5, the outer circumferential surface of the first threaded rod 5 is threadedly connected to a first threaded sleeve 6, the bottom of the first threaded sleeve 6 passes through the first threaded rod 5 and is fixed to the surface of the top of the water baffle 2, a first motor 7 is fixed to the surface of one side of one of the mounting seats 1, one side of one of the first threaded rods 5 passes through the mounting seat 1 and is fixed to the output end of the first motor 7, because the inner cavity of the rod groove 4 can play a role of resistance and limitation for the first threaded sleeve 6, so that when the first threaded rod 5 can rotate, the first threaded sleeve 6 can drive the water baffle 2 to move in a horizontal direction under the cooperation between the internal thread structure of the inner wall of the first threaded sleeve 6 and the external thread structure of the outer circumferential surface of the first threaded rod 5.
[0024] Further as Figure 3 As shown, it is worth explaining in detail that an opening 11 is provided on the surface of the top of the rod groove 4, and a second gear 12 is fixedly sleeved at a position near the opening 11 on the outer circumference of the first threaded rod 5, and a first gear 10 is meshed on the top of the second gear 12, and a support block 8 is fixed on the surface of the top of the mounting base 1, and a rotating shaft 9 is rotatably connected through the middle position of the two support blocks 8, and both sides of the outer circumference of the rotating shaft 9 are fixed to the inner wall of the first gear 10, and when the first threaded rod 5 can rotate, it drives the second gear 12 to rotate, so that the rotating shaft 9 can be in a rotating state under the meshing action of the second gear 12 and the first gear 10 and the support action of the support block 8.
[0025] Further as Figure 6 As shown, it is worth explaining in detail that a first slot 18 is opened on the surface of one side of one of the limiting plates 14, and a first inserting strip 19 is inserted inside the first slot 18. One side of the first inserting strip 19 passes through the first slot 18 and is fixed to the surface of the other limiting plate 14. When the two limiting plates 14 are attached, the first inserting strip 19 on the surface of one side of the limiting plate 14 can extend to the inner cavity of the first slot 18, thereby improving the sealing of the connection between the two limiting plates 14.
[0026] This solution has the following working process: in actual use, when the two water retaining plates 2 need to be closed to achieve waterproofing, the first motor 7 is started to rotate one of the first threaded rods 5, so that the rotating shaft 9 can be in a rotating state under the meshing action of the second gear 12 and the first gear 10 and the support action of the support block 8, so that the two first threaded rods 5 can be rotated synchronously under the meshing action between the other group of first gears 10 and the second gear 12. Since the inner cavity of the rod groove 4 can play a role of resistance and limitation for the first threaded sleeve 6, and the outer peripheral surface structures of the two first threaded rods 5 are arranged in opposite directions to each other, the first threaded sleeve 6 can make the two water retaining plates 2 close to each other under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer peripheral surface of the first threaded rod 5. The plates 2 can move toward each other so that the two water baffles 2 fit together, so that the two water baffles 2 cooperate to play a waterproof role, and then the second motor 23 is started to rotate one of the second threaded rods 17, so that the two second threaded rods 17 can rotate synchronously under the connection between the pulley 24 and the connecting belt 20, so that the limiting plate 14 can move vertically downward under the cooperation of the threaded structure between the second threaded rod 17 and the opening 15 and the interference and limitation between the opening 15 and the limiting shaft 16, so that the two limiting plates 14 can be embedded in the mud of the river channel, thereby improving the waterproof effect of the limiting plate 14, thereby avoiding the situation that water will seep in from the gap at the bottom of the water baffle 2 after long-term use, and improving the stability of the water baffle 2 when waterproofing.
[0027] According to the above working process, it can be known that: by starting the second motor 23, the two second threaded rods 17 can be rotated, so that the limiting plate 14 can move in the vertical direction, so as to be embedded in the mud in the river or channel, so as to improve the waterproof effect of the water retaining plate 2, thereby avoiding the situation that water flow will penetrate into the gap at the bottom of the water retaining plate 2 after long-term use, and improve the stability of the water retaining plate 2 when waterproof, thereby improving the practicality of the device, and by starting the first motor 7, one of the first threaded rods 5 can be rotated, so that the rotating shaft 9 can be rotated under the meshing action between the first gear 10 and the second gear 12, so that the two first threaded rods 5 can rotate synchronously, so as to facilitate the two water retaining plates 2 to move in the direction close to each other, and have a waterproof effect after being fitted, thereby further improving the practicality of the device.

One side of the second insertion strip 21 passes through the second slot 22 and is fixed to the surface of the other water baffle 2. When the water baffles 2 are fitted together, the second insertion strip 21 can be embedded in the second slot 22 at an adjacent position, so that the sealing effect can be achieved when the two water baffles 2 are fitted together, thereby improving the waterproof effect of the water baffle 2 when it is sealed.
[0029] In summary: by starting the second motor 23, the two second threaded rods 17 can be rotated, so that the limiting plate 14 can move in the vertical direction, so as to be embedded in the mud in the river or channel, so as to improve the waterproof effect of the water retaining plate 2, so as to avoid the situation that water flow will penetrate into the gap at the bottom of the water retaining plate 2 after long-term use, and improve the stability of the water retaining plate 2 when waterproof, thereby improving the practicality of the device; by starting the first motor 7, one of the first threaded rods 5 can be rotated, so that the rotating shaft 9 can be rotated under the meshing action between the first gear 10 and the second gear 12, so that the two first threaded rods 5 can be rotated synchronously, so as to facilitate the two water retaining plates 2 to move in the direction close to each other and play a waterproof effect after being fitted, thereby further improving the practicality of the device; when the water retaining plates 2 are fitted together, the second insert 21 can be embedded in the second slot 22 at the adjacent position, so that the sealing effect when the two water retaining plates 2 are fitted can be achieved, thereby improving the waterproof effect of the water retaining plates 2 when sealed.
