[0002] In water conservancy engineering, a water stopping device is needed to effectively block the water flow of the waterway in the construction area. As the core equipment for water flow blocking, the degree of adaptation of the water stopping device to the waterway working condition directly determines the blocking effect.

[0003] The existing waterway structure presents significant diversity characteristics. The difference in the shape of the waterway slope is one of the key factors affecting the adaptability of the water stopping device. The existing waterway slope generally has a certain inclination angle, and the slope gradient values of different water conservancy projects differ greatly, covering various slope types from gentle slope to steep slope. This uncertainty in slope gradient puts high demands on the adaptability of the water stopping device.

[0027] Example 1, refer to the appendix of the instruction manual. Figures 1-15 A water-stopping device for water conservancy construction includes a water-stopping plate 1. Two bottom sliding plates 2 that slide relative to each other are provided at the bottom of the water-stopping plate 1. The bottom sliding plates 2 are provided with grooves. A slider that cooperates with the grooves is fixedly connected to the bottom of the water-stopping plate 1, so that the bottom sliding plates 2 can slide on the water-stopping plate 1. The bottom sliding plates 2 are provided on both sides of the water-stopping plate 1. Support rods 3 are rotatably connected to both ends of the bottom sliding plates 2. The support rods 3 at both ends of the bottom sliding plates 2 are arranged in parallel. The end of the support rod 3 away from the bottom sliding plate 2 is rotatably connected to a top connecting plate 4. The support rod 3 has a slide rail 5 inside, and multiple longitudinally arranged extension plates 6 are set between two support rods 3. Both ends of the extension plates 6 are fixedly connected to the slide shafts 7 that cooperate with the slide rail 5. When in use, when the support rod 3 swings, the slide rail 5 drives the slide shafts 7 to move, so that the adjacent extension plates 6 slide synchronously with the swing angle of the slide rail 5. This allows the extension plates 6 to slide synchronously after the support rod 3 is adjusted to a suitable angle, thereby achieving the isolation of the waterway. The middle position of the waterstop plate 1 is provided with a distance control drive structure for controlling the bottom sliding plate 2 to slide in a direction away from or close to each other, and an angle control drive structure for controlling the angle between the support rod 3 and the bottom sliding plate 2.

[0028] The waterstop plate 1 has a mounting groove 8 in the middle. The distance control drive structure includes a bottom threaded rod 9 that is slidably connected to the bottom of the mounting groove 8. Both ends of the bottom threaded rod 9 are provided with bottom limiting sliding shafts. The bottom of the mounting groove 8 is provided with a bottom limiting hole that is slidably connected to the bottom limiting sliding shafts. This configuration allows the bottom threaded rod 9 to rotate on the mounting groove 8 and slide up and down inside the mounting groove 8. Both ends of the bottom threaded rod 9 are provided with control springs 10. A distance drive block 11 is threadedly connected to the bottom threaded rod 9. A bottom connecting rod 12 is connected between the bottom sliding plate 2 and the distance drive block 11. In use, by rotating the bottom threaded rod 9, the distance drive block 11 slides on the bottom threaded rod 9, thereby pushing the bottom sliding plate 2 to move closer to or further away from the bottom threaded rod 9. The angle control drive structure includes a top threaded rod 13 that slides vertically on the top of the mounting groove 8. Both ends of the top threaded rod 13 are fixedly connected to a top limiting sliding shaft. The top of the mounting groove 8 has a top limiting hole that slides vertically with the top limiting sliding shaft. This configuration allows the top threaded rod 13 to rotate on the mounting groove 8 and slide vertically inside the mounting groove 8. Both ends of the top threaded rod 13 are equipped with drive springs 14. An angle drive block 15 is threaded onto the top threaded rod 13. A top connecting rod 16 connects the support rod 3 near the mounting groove 8 and the angle drive block 15. In use, after the bottom sliding plate 2 is fixed, rotating the top threaded rod 13 pushes the support rod 3 to move via the top connecting rod 16, adjusting the angle between the support rod 3 and the bottom sliding plate 2, thereby allowing the support rod 3 to fit against the waterway sidewall with different slope gradients.

[0029] The bottom threaded rod 9 is fixedly connected to the upper end of the bottom connecting sleeve 17. The inner wall of the bottom connecting sleeve 17 is provided with a plurality of bottom connecting balls 18. The lower end of the top threaded rod 13 is provided with a plurality of bottom connecting grooves 19 that cooperate with the bottom connecting balls 18. The bottom connecting grooves 19 are vertically arranged. The upper end of the bottom connecting grooves 19 is provided with a bottom annular groove 20 that cooperates with the bottom connecting balls 18. In the initial state, the bottom connecting ball 18 is located inside the bottom connecting groove 19. When the top threaded rod 13 rotates, it drives the bottom threaded rod 9 to rotate synchronously.

[0030] A top connecting sleeve 21 is fixedly connected to the upper end of the top threaded rod 13. Multiple top connecting balls 22 are provided on the inner wall of the top connecting sleeve 21. A control base 23 is fixedly connected to the top of the waterstop plate 1. A drive shaft 24 is slidably connected to the inside of the control base 23. Multiple top connecting grooves 25 that cooperate with the top connecting balls 22 are opened at the lower end of the drive shaft 24. A top annular groove 26 that cooperates with the top connecting balls 22 is opened at the upper end of the top connecting grooves 25. In the initial state, the top connecting ball 22 is located inside the top connecting groove 25. When the drive shaft 24 rotates, it drives the top threaded rod 13 to rotate synchronously.

[0031] In use, the device is placed inside the waterway, with the bottom sliding plate 2 and support rod 3 initially located inside the waterstop plate 1. The drive shaft 24 is rotated, and the drive shaft 24 drives the top threaded rod 13 to rotate through the top connecting ball 22 and the top connecting groove 25. The top threaded rod 13 drives the bottom threaded rod 9 to rotate through the bottom connecting ball 18 and the bottom connecting groove 19. This causes the angle drive block 15 and the distance drive block 11 to slide on the top threaded rod 13 and the bottom threaded rod 9, respectively. The angle drive block 15 and the distance drive block 11 drive the support rod 3 and the bottom sliding plate 2 to move away from the placement groove 8 through the top connecting rod 16 and the bottom connecting rod 12. This pushes the bottom sliding plate 2, the support rod 3, and the extension plate 6 out of the waterstop plate 1, thereby adapting it to waterways of different widths. When the bottom sliding plate 2 and the support rod 3 are moved synchronously away from the placement groove 8 until the end of the bottom sliding plate 2 away from the placement groove 8 contacts the two side walls of the waterway, the top threaded rod 13 continues to rotate. The top threaded rod 13 synchronously drives the bottom threaded rod 9 to rotate. At this time, the bottom threaded rod 9 continues to rotate, and the distance drive block 11 cannot continue to slide downward under the action of the bottom connecting rod 12. At this time, the distance drive block 11 pushes the bottom threaded rod 9 to move upward, compressing the control spring 10 at the upper end of the bottom threaded rod 9 and stretching the control spring 10 at the lower end of the bottom threaded rod 9. The bottom threaded rod 9 synchronously drives the bottom connecting sleeve 17 to move upward. The bottom connecting ball 18 slides upward inside the bottom connecting groove 19 to the bottom annular groove 20. The bottom connecting ball 18 cannot drive the top threaded rod 13 to rotate. At this time, the top threaded rod 13 continues to rotate, and the bottom threaded rod 9 cannot rotate synchronously.

[0032] Subsequently, the top threaded rod 13 continues to rotate via the drive shaft 24. The angle drive block 15 controls the support rod 3 to swing towards the side wall of the waterway via the top connecting rod 16 until the support rod 3 near the side wall of the waterway is in contact with the side wall. Under the action of the top connecting rod 16, the angle drive block 15 is prevented from moving downward. The top threaded rod 13 continues to rotate, and under the action of the angle drive block 15, the top threaded rod 13 is pushed upward, compressing the drive spring 14 at the upper end of the top threaded rod 13 and stretching the drive spring 14 at the lower end of the top threaded rod 13. The sleeve 21 moves upward synchronously until the top connecting ball 22 slides upward into the top annular groove 26 inside the top connecting groove 25. At this time, the top connecting sleeve 21 and the drive shaft 24 rotate relative to each other. When the drive shaft 24 continues to rotate, the top threaded rod 13 will not rotate with the drive shaft 24. When the top threaded rod 13 moves upward, the bottom connecting ball 18 slides out from the bottom annular groove 20 and slides into the bottom connecting groove 19. At this time, when the top threaded rod 13 rotates, it can drive the bottom threaded rod 9 to rotate through the bottom connecting ball 18 and the bottom connecting groove 19.

[0033] After use, pull the drive shaft 24 upwards to allow the top connecting ball 22 to slide from the top annular groove 26 into the top connecting groove 25, so that when the drive shaft 24 rotates, it can drive the bottom threaded rod 9 to rotate through the top connecting sleeve 21. Rotate the drive shaft 24 in the opposite direction. At this time, the top threaded rod 13 and the bottom threaded rod 9 rotate synchronously in opposite directions. Under the action of the drive spring 14 and the control spring 10, the top threaded rod 13 and the bottom threaded rod 9 are pushed to their initial positions. At this time, continue to rotate the top threaded rod 13 and the bottom threaded rod 9. The angle drive block 15 and the distance drive block 11 move upwards synchronously, thereby retracting the bottom sliding plate 2, the support rod 3, and the extension plate 6 into the waterstop plate 1. When the bottom sliding plate 2 is retracted to its limit position, the bottom sliding plate 2 can no longer move towards the bottom threaded rod 9. At this time, continue to rotate the bottom threaded rod 9. The bottom threaded rod 9 slides downwards to compress the control spring 10 at the lower end of the bottom threaded rod 9 and stretches the control spring 10 at the upper end of the bottom threaded rod 9. At this time, the bottom connecting sleeve 17 moves downwards synchronously, and the bottom connecting ball 18 and the bottom connecting groove... 19 disengages, and the rotation of the top threaded rod 13 does not cause the bottom threaded rod 9 to rotate; then the drive shaft 24 continues to rotate, and the drive shaft 24 continues to drive the top threaded rod 13 to rotate, and the angle drive block 15 continues to move upward, driving the support rod 3 to swing through the top connecting rod 16 until the support rod 3 is in a vertical state. Then, the position of the support rod 3 is restricted by the limiting plate set inside the waterstop plate 1, so that the support rod 3 cannot continue to swing towards the angle drive block 15, and the top connecting rod 16 cannot pull the support rod 3 to continue to move towards the mounting groove 8. The drive shaft 24 continues to rotate, causing the top threaded rod 13 to rotate. Under the action of the angle drive block 15, the top threaded rod 13 is pushed downward, compressing the drive spring 14 at the lower end of the top threaded rod 13 and stretching the drive spring 14 at the upper end of the top threaded rod 13. When the top threaded rod 13 moves downward, the bottom connecting ball 18 slides into the bottom connecting groove 19, and the top connecting ball 22 slides out from the top connecting groove 25. At this time, the rotation of the drive shaft 24 cannot drive the top threaded rod 13 to rotate.

[0034] When used again, push the drive shaft 24 downwards, and the top connecting ball 22 slides back into the top connecting groove 25, driving the top threaded rod 13 and the bottom threaded rod 9 to rotate via the drive shaft 24.

[0035] In Embodiment 2, based on Embodiment 1, a locking slider 27 is slidably connected to the inside of the control base 23, and multiple circumferentially distributed locking vertical plates 28 are fixedly connected to the outer wall of the top connecting sleeve 21. Multiple locking vertical grooves 29 that cooperate with the locking vertical plates 28 are opened inside the locking slider 27. Rounded corners are provided on the upper part of the locking vertical plates 28 and the lower end of the locking vertical grooves 29. A downward pressure spring 30 is provided between the locking slider 27 and the control base 23. In the initial state, the locking slider 27 is pushed downward by the action of the downward pressure spring 30. Locking grooves 31 are provided on both sides of the locking slider 27. A trapezoidal control slider 32 that cooperates with the top connecting sleeve 21 is slidably connected inside the locking groove 31. A limiting slider 33 that cooperates with the locking groove 31 is slidably connected on the control base 23. A push spring 34 is provided between the limiting slider 33 and the control base 23. In the initial state, the limiting slider 33 is pushed towards the drive shaft 24 by the action of the push spring 34.

[0036] In the initial state, after the locking slider 27 moves upward to the limit position, the locking groove 31 and the limiting slider 33 are at the same height. Under the action of the push spring 34, the limiting slider 33 is pushed to insert into the locking groove 31. Then the limiting slider 33 pushes the trapezoidal control slider 32 to move towards the drive shaft 24. At this time, the locking slider 27 is restricted to the current position by the limiting slider 33 and the locking groove 31. In use, when the top connecting sleeve 21 moves upward to its limit position, the top connecting ball 22 slides into the top annular groove 26. At this time, the top of the top connecting sleeve 21 contacts the inclined surface of the trapezoidal control slider 32. The top connecting sleeve 21 pushes the trapezoidal control slider 32 away from the drive shaft 24 until the trapezoidal control slider 32 pushes the limit slider 33 out of the locking groove 31. At this time, under the action of the downward spring 30, the locking slider 27 is pushed downward, and the locking vertical plate 28 is inserted into the locking vertical groove 29. Thus, the top connecting sleeve 21 is fixed by the locking slider 27 to prevent the top threaded rod 13 and the bottom threaded rod 9 from rotating. This is used to fix the extended bottom sliding plate 2 and support rod 3 so that they fit against the side wall of the waterway. When it is necessary to retract the bottom sliding plate 2 and support rod 3, the control locking slider 27 is moved upward to its limit position.

[0037] In Example 3, based on Example 2, a one-way drive ring 35 is rotatably connected to the control base 23. A one-way bearing is installed between the one-way drive ring 35 and the control base 23. Two inclined grooves 36 are opened on the one-way drive ring 35. The grooves 36 are inclined downward. Height control shafts 37 that cooperate with the grooves 36 are fixedly connected to both sides of the drive shaft 24. A mating plate 38 that cooperates with the locking slider 27 is fixedly connected to the drive shaft 24.

[0038] In the initial state, the height control shaft 37 is engaged at the bottom of the inclined groove 36. At this time, the drive shaft 24 drives the one-way drive ring 35 to rotate through the height control shaft 37 and the inclined groove 36 until the top threaded rod 13 slides upward to the limit position. Then, the top connecting sleeve 21 moves upward to the limit position, the locking slider 27 moves downward, and the locking vertical plate 28 is engaged in the locking vertical groove 29. When in use, when the bottom sliding plate 2, support rod 3 and extension plate 6 need to be retracted into the waterstop plate 1, the drive shaft 24 is rotated clockwise. At this time, the one-way drive ring 35 cannot rotate in the opposite direction under the action of the one-way bearing. Then the height control shaft 37 moves upward along the inclined groove 36, thereby driving the drive shaft 24 to move upward. Then the top connecting ball 22 slides from the inside of the top ring groove 26 into the inside of the top connecting groove 25, thereby driving the top threaded rod 13 to rotate through the drive shaft 24 until the top threaded rod 13 moves downward to the limit position. The top connecting sleeve 21 moves downward synchronously, and the top connecting ball 22 and the top connecting groove 25 disengage. When it is necessary to push the bottom sliding plate 2, support rod 3 and extension plate 6 out of the waterstop plate 1, rotate the drive shaft 24 counterclockwise. At this time, the height control shaft 37 is engaged in the lower end of the inclined groove 36. Then the height control shaft 37 slides down along the inclined groove 36, and the drive shaft 24 moves down synchronously. At this time, the top connecting ball 22 slides into the top connecting groove 25.

[0039] A drive sleeve 39 is rotatably connected to the control base 23. The drive sleeve 39 is slidably connected to the drive shaft 24. The drive sleeve 39 is connected to the circumferential drive device, which can be driven by a motor and a chain.

[0040] In embodiment four, a bottom sealing rubber strip 40 is fixedly connected to the bottom of the waterstop plate 1, a side wall sealing rubber strip 41 is fixedly connected to the support rod 3 on the side away from the placement groove 8, and an extension sealing rubber strip 42 is fixedly connected to the bottom of the bottom sliding plate 2. This arrangement facilitates sealing of the water channel and the bottom of the waterstop plate 1, as well as the side wall of the water channel and the support rod 3.

[0041] In embodiment 5, a trapezoidal connecting slider 43 is fixedly connected to one end of the extension plate 6, and a trapezoidal groove 44 that cooperates with the connecting slider 43 is opened at the other end of the extension plate 6. The upper and lower adjacent extension plates 6 are connected by the connecting slider 43 and the trapezoidal groove 44. This arrangement allows the upper and lower adjacent extension plates 6 to be connected to each other to improve the sealing effect, while not affecting the sliding between the extension plates 6.

[0042] In Example 6, a fixing frame 45 is fixedly connected to one side of the waterstop plate 1, and a connecting beam 46 is fixedly connected to the top of the fixing frame 45. Both ends of the connecting beam 46 are fixedly connected to fixing bases 47. In use, the fixing bases 47 are fixed to both sides of the waterway, and the waterstop plate 1 is placed inside the waterway.

[0043] A reinforcing plate 48 is fixedly connected to the side of the fixing frame 45 away from the waterstop plate 1, thereby reinforcing the fixing frame 45.

[0044] An auxiliary support threaded rod 49 is rotatably connected to the fixed frame 45. A pressing support plate 50 is provided at the bottom of the auxiliary support threaded rod 49. Multiple evenly distributed fixing rods 51 are fixedly connected to the lower end face of the pressing support plate 50. In use, the auxiliary support threaded rod 49 is rotated and moves downward. The auxiliary support threaded rod 49 pushes the pressing support plate 50 downward, and the fixing rods 51 are driven into the bottom of the waterway, thereby providing support force to the fixed frame 45 and thus improving the support force on the waterstop plate 1.

[0045] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
