Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a leak plugging and drainage device for water conservancy projects. Background Art
[0002] In water conservancy projects, there are often underground rivers around reservoirs. When the underground river water is abundant, it is introduced into the reservoir through the cave to replenish the reservoir water. When the underground river water dries up in the dry season, the water in the reservoir will enter the underground river through the cave, resulting in a decrease in the water storage capacity of the reservoir. Therefore, a leak-plugging and drainage device is often used, that is, a drainage pipe is used to connect the reservoir and the underground river for one-way controlled drainage.
[0003] Existing leak-plugging and drainage devices usually control the introduction and blocking of water flow on both sides by setting valves. They cannot automatically adjust according to changes in water levels on both sides. Workers need to patrol and operate valves to control them. The operation is cumbersome and reduces drainage efficiency. In addition, the partitions on both sides of the water pipes are easily clogged with mud, etc., which is inconvenient to clean, resulting in poor circulation and further affecting the drainage rate.
[0004] Therefore, in view of the problem that the above-mentioned existing leak-plugging and drainage devices use a single valve to control the introduction and blocking, and cannot automatically adjust according to the changes in water levels on both sides, which increases the labor intensity of the staff, is time-consuming and labor-intensive to operate, and reduces the drainage efficiency. In addition, the partitions on both sides of the water pipe are easily clogged with mud, etc., which is inconvenient to clean, resulting in poor circulation and further affecting the drainage rate, a water conservancy project leak-plugging and drainage device can be designed. Through the different water pressures on both sides, the movable disk is controlled to move, driving the blocking disk to open or block the water holes on the blocking disk, and automatically adjusting according to the water level conditions on both sides to perform drainage or blocking work. At the same time, the two cleaning scrapers can be driven to clean the surface of the blocking net by rotating the rotating column to prevent the mesh from being clogged and improve the fluidity of the blocking net. Utility Model Content

[0014] Beneficial effects of the utility model:
[0015] 1. When the water level on the cave side is high, the pressure on the left side is higher than that on the right side, and the water flow pushes the blocking disc and the movable disc to move right, exposing the water holes on the surface of the blocking disc.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] See also Figures 1-6 The utility model provides an embodiment of a water conservancy project leakage plugging and drainage device, including a drainage pipe 1; it also includes a blocking disc 2, a blocking disc 4, a movable disc 5, a positioning disc 7, a spring 8, a rotating column 10 and a cleaning scraper 11. The left end of the inner side of the drainage pipe 1 is fixedly connected with the blocking disc 2. The middle part of the blocking disc 2 is provided with a water hole 3. The inner side of the water hole 3 is penetrated by a blocking disc 4. The right end of the blocking disc 4 is fixedly connected with the movable disc 5. The right end of the inner side of the drainage pipe 1 is symmetrically fixed with four fixing plates 6. The middle parts of the four fixing plates 6 are commonly fixedly connected with a positioning disc 7. A spring 8 is fixedly connected between the positioning disc 7 and the movable disc 5. The left and right ends of the drainage pipe 1 are fixedly connected with the same baffle 9. The middle part of the blocking disc 4, the movable disc 5 and the positioning disc 7 is movably penetrated by a rotating column 10. The left and right ends of the rotating column 10 are symmetrically fixedly connected with cleaning scrapers 11. The left end of the drainage pipe 1 is connected to the karst cave connected to the underground river. When the water level on the left side is too high, the pressure on the left side will be higher than that on the right side. Then, the water on the left side will flow into the reservoir in large quantities for drainage and replenishment. When the underground river dries up and the water level drops, the pressure on the right side will be higher than that on the left side. Under the push of the spring 8, the movable plate 5 will be pushed to the left, and the blocking plate 4 will be reinserted into the water hole 3 in the blocking plate 2 to seal it, preventing the water storage capacity of the reservoir from being lost, thereby achieving the purpose of blocking and drainage. The device can automatically adjust according to the water level conditions on both sides to perform drainage or blocking work, avoiding the trouble of controlling the valve operation, saving time and effort, and improving work efficiency. At the same time, when there is a lot of debris attached to the baffle nets 9 on both sides, the rotating column 10 can be rotated to drive the two cleaning scrapers 11 to clean the surface of the baffle net 9 to prevent the mesh from being blocked, improve the fluidity of the baffle net 9, and increase the flow rate of river water during drainage.
[0026] See also Figure 4-Figure 6In this embodiment, the right end of the movable disk 5 is fixedly connected with an outer ring 12, the left end of the positioning disk 7 is fixedly connected with an inner ring 13, and the left end of the inner ring 13 is inserted into the inner side of the outer ring 12. The outer ring 12 and the inner ring 13 wrap the spring 8 therein to prevent the river water from corroding the spring 8. The left end of the movable disk 5 is fixedly connected with an elastic sealing gasket 14, and the right end of the outer ring 12 is fixedly connected with an elastic sealing gasket 2 15. The elastic sealing gasket 14 improves the sealing performance of the sealing disk 4 when sealing the water hole 3, and the elastic sealing gasket 2 15 improves the sealing performance of the gap between the outer ring 12 and the inner ring 13. A guide column 16 is fixedly connected between the blocking disk 2 and each fixed plate 6, and each guide column 16 movably passes through the movable disk 5 and the elastic sealing gasket 14. The guide column 16 can improve the stability of the movable disk 5 when it moves.
[0027] See also Figure 1-Figure 3 In this embodiment, the middle parts of the two baffles 9 are fixedly connected with positioning pieces 17, and the left and right ends of the rotating column 10 are rotatably connected to the surfaces of the two positioning pieces 17. The two positioning pieces 17 are used for the rotation connection of the rotating column 10. The middle part of the right positioning piece 17 is movably connected with a connecting shaft 18. The left end of the connecting shaft 18 is fixedly connected to the rotating column 10, and the right end of the connecting shaft 18 is fixedly connected with a knob 19. Rotating the knob 19 drives the connecting shaft 18 to rotate, thereby driving the rotating column 10 to rotate. A fixing ring 20 is fixedly connected to the outer side of the right end of the drainage tube 1. A plurality of mounting holes 21 are opened on the surface of the fixing ring 20. The fixing ring 20 and the mounting holes 21 are used to install the entire device in the corresponding connecting pipeline.
[0028] When working, the entire device is installed in the corresponding connecting pipeline through the fixing ring 20 and the mounting hole 21. The left end of the drainage pipe 1 is connected to the cave connected to the underground river, and the right end of the drainage pipe 1 is connected to one side of the reservoir. When the water level on the cave side is high, the pressure on the left side is higher than that on the right side, and the water flow pushes the blocking plate 4 and the movable plate 5 to move right, exposing the water hole 3 opened on the surface of the barrier plate 2, and a large amount of water on the left side flows into the reservoir for drainage replenishment. When the underground river dries up and the water level drops, the pressure on the right side is higher than that on the left side, and the movable plate 5 is pushed to the left under the push of the spring 8, and the blocking plate 4 is reinserted into the water hole 3 in the barrier plate 2 for blocking to prevent the loss of water storage in the reservoir. When there is a lot of debris attached to the baffle nets 9 on both sides, the knob 19 can be rotated externally to drive the rotating column 10 to rotate through the connecting shaft 18. The rotating column 10 drives the two cleaning scrapers 11 to clean the surface of the baffle net 9 to prevent the mesh from being blocked, thereby improving the fluidity of the baffle net 9 and increasing the river water flow rate during drainage.
[0029] Through the above steps, the device can control the movable disk 5 to move according to the different water pressures on both sides, drive the sealing disk 4 to open or block the water hole 3 opened on the blocking disk 2, and automatically adjust according to the water level conditions on both sides to perform drainage or blocking work, avoiding the trouble of controlling the valve operation, saving time and effort, and improving work efficiency. At the same time, the two cleaning scrapers 11 can be driven by rotating the rotating column 10 to clean the surface of the baffle 9 to prevent the mesh from being blocked, improve the fluidity of the baffle 9, and increase the flow rate of river water during drainage, so as to solve the problem that the existing plugging and drainage device uses a single valve to control the introduction and blocking, and cannot automatically adjust according to the changes in the water levels on both sides, which increases the labor intensity of the staff, is time-consuming and labor-intensive to operate, and reduces the drainage efficiency. Moreover, the baffles on both sides of the water pipe are easily blocked by mud, etc., which is inconvenient to clean, resulting in poor circulation, further affecting the drainage rate.
