Caisson-type construction water-stopping device has good sealing performance and stability, and is suitable for construction sites with large water depth. It can be adjusted according to actual conditions to keep the construction area dry and provide a relatively safe working environment for construction personnel. In addition to caisson-type construction water-stopping device, there are other types of water-stopping devices, such as temporary arch gates, temporary retaining walls, etc.

[0005] When the device is in use, the device uses two power components to move the waterstop plate. However, the two power components are prone to asynchrony when in use, which can easily cause the waterstop plate to get stuck and the power components to be damaged. Impurities are easily stuck in the slot corresponding to the sealing plate below, thereby affecting the use of the waterstop plate. Therefore, we need to propose a waterstop device for water conservancy project construction. Summary of the invention

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A water-stopping device for water conservancy project construction includes a support frame 1, a motor 2 is fixedly connected to the upper end of the support frame 1, a screw 3 is fixedly connected to the output shaft of the motor 2, the screw 3 is connected to the support frame 1 through a bearing, a water-stop plate 4 is threadedly connected to the outer side of the screw 3, the water-stop plate 4 is slidably connected to the support frame 1, a cleaning ring 5 is fixedly connected to the upper end of the water-stop plate 4, the cleaning ring 5 contacts the screw 3, a limiting hole 6 is provided inside the water-stop plate 4, a slider 7 is fixedly connected to the outer side of the water-stop plate 4, and an electromagnetic block 10 is fixedly connected to the upper end of the support frame 1.

[0026] A slide groove 8 is provided inside the support frame 1 , and the slide groove 8 is slidably connected to the slider 7 .

[0027] An installation groove 9 is provided inside the upper end of the support frame 1 , and a fixing rod 11 is fixedly connected inside the installation groove 9 .

[0028] A spring 12 is arranged on the outer side of the fixing rod 11 , one end of the spring 12 is fixedly connected to the mounting groove 9 , and the other end of the spring 12 is fixedly connected to the limiting plate 13 .

[0029] Through the design of the spring 12 , the spring 12 uses elasticity to control the position of the limiting plate 13 .

[0030] A limit plate 13 is slidably connected inside the installation groove 9 , and a dust discharge groove 14 is provided at the bottom end of the support frame 1 .

[0031] Through the design of the limiting plate 13, when the water stop plate 4 moves upward to the top, the limiting hole 6 squeezes the limiting plate 13, the limiting plate 13 moves toward the direction of the screw 3, and then enters the limiting hole 6. Under the action of the spring 12, it is stuck in the limiting hole 6, and the limiting plate 13 limits the water stop plate 4.

[0032] An extrusion plate 15 is slidably connected inside the ash discharge chute 14 , and the extrusion plate 15 is fixedly connected to the water stop plate 4 .

[0033] Through the design of the ash discharge trough 14, small pieces of impurities on the bottom of the water fall under the water stop plate 4 and accumulate behind the triangular plate 18. When they reach a certain height, they will be carried away by the water flow or fall into the ash discharge trough 14 and discharged from the ash discharge trough 14.

[0034] The outer side of the water stop plate 4 is fixedly connected with a mounting strip 16 , and the outer side of the mounting strip 16 is fixedly connected with a diverter plate 17 .

[0035] Through the design of the diverter plate 17, the diverter plate 17 is installed in the water inlet direction of the water stop plate 4 through the mounting strip 16. When the water flows through the diverter plate 17, the water flows to both sides under the influence of the slope of the diverter plate 17, avoiding the water flow directly impacting the water stop plate 4 and causing damage to the water stop plate 4.

[0036] A triangular plate 18 is fixedly connected to the bottom end of the support frame 1 , and the triangular plate 18 is slidably connected to the water stop plate 4 .

[0037] Through the design of the triangular plate 18, when water flows through the triangular plate 18, large impurities on the bottom of the water are driven by the water flow, pass through the slope of the triangular plate 18, and fall behind the support frame 1, thereby preventing large impurities from being stuck under the water stop plate 4 and affecting the closure of the lower end of the water stop plate 4 and the support frame 1.

[0038] Working principle: When the utility model is used, the motor 2 drives the screw rod 3 to rotate, and the screw rod 3 controls the position of the water stop plate 4 through the threaded movement between the screw rod 3 and the water stop plate 4. When the water stop plate 4 moves, the slider 7 slides in the slide groove 8 to guide the device to prevent the water stop plate 4 from rotating with the screw rod 3. When the water stop plate 4 moves upward to the top end, the limiting hole 6 squeezes the limiting plate 13, and the limiting plate 13 moves toward the direction of the screw rod 3, and then enters the limiting hole 6. Under the action of the spring 12, it is stuck in the limiting hole 6. The limiting plate 13 limits the water stop plate 4 and fixes the water stop plate 4 above the support frame 1. The water flow begins to flow. When the water flow passes through the triangular plate 18, the large impurities on the bottom of the water are driven by the water flow and pass through the slope of the triangular plate 18 and fall behind the support frame 1, so as to prevent large impurities from being stuck in the water stop. The bottom of the plate 4 affects the closure of the lower end of the water stop plate 4 and the support frame 1. After the small and medium-sized impurities on the bottom of the water fall under the water stop plate 4, they accumulate behind the triangular plate 18. When they reach a certain height, they will be carried away by the water flow, or fall into the ash discharge trough 14 and be discharged from the ash discharge trough 14. When the water stop plate 4 needs to be dropped, the electromagnetic block 10 is energized to attract the limit plate 13 to release the limit on the water stop plate 4. The screw 3 controls the water stop plate 4 to move downward, and the extrusion plate 15 squeezes the ash inside the ash discharge trough 14 to prevent the ash discharge trough 14 from being blocked by impurities and causing the ash to be unable to be discharged. The diverter plate 17 is installed in the water inlet direction of the water stop plate 4 through the mounting strip 16. When the water flows through the diverter plate 17, the water flows to both sides under the influence of the slope of the diverter plate 17 to avoid the water flow directly impacting the water stop plate 4 and causing damage to the water stop plate 4.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
