By filling and draining pipelines with water (or gas) to inflate it, the water filling and draining process of the rubber dam is a key link for realizing functions such as water level regulation, flood control, irrigation, and power generation.

[0003] The rubber dam water filling and draining device disclosed in the authorized publication number "CN212103929U" records the technical problem of "filtering the water filled into the rubber dam to reduce the damage and destruction of the rubber dam bag".

However, since the filtering device of this water filling pipeline is located inside the flange, when cleaning the filtering part, the entire flange needs to be disassembled, and it needs to be assembled again after cleaning, which is cumbersome and time-consuming.

[0032] To solve this technical problem, the present utility model provides a rubber dam water filling and draining device.

[0034] In order to enable the personnel in the technical field to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings.

[0035] Embodiment 1:

[0036] Please refer to Figures 1 - 3 , A rubber dam filling and draining device, which includes a dam foundation 1. A rubber dam bag 2 is installed on the top of the dam foundation 1. One side of one end of the rubber dam bag 2 is fixedly connected to a water inlet pipe 3. A water supply pipe 4 is arranged at the end of the water inlet pipe 3 far from the rubber dam bag 2. A filtering component 5 is arranged between the water inlet pipe 3 and the water supply pipe 4. Both ends of the filtering component 5 are fixedly connected to the water inlet pipe 3 and the water supply pipe 4 respectively. A reserved groove is opened on the top of the dam foundation 1. The bottom of the filtering component 5 is in clearance fit with the reserved groove. A cleaning component 6 is arranged inside the filtering component 5. One end of the rubber dam bag 2 close to the water inlet pipe 3 is fixedly connected to a drain pipe 7, and the drain pipe 7 is arranged at the end far from the water inlet pipe 3. A water valve is arranged inside the drain pipe 7.

[0037] Through the connection setting of the water supply pipe 4, the water inlet pipe 3 and the filtering component 5, the inside of the rubber dam bag 2 can be filled with water;

[0038] Through the setting of the filtering component 5, the water flowing into the inside of the water supply pipe 4 can be filtered, so as to reduce the damage to the inner wall of the rubber dam bag 2 caused by the residual impurities and stones in the water entering the inside of the rubber dam bag 2. At the same time, when the rubber dam bag 2 is urgently needed, the filtering effect of the water flow in the water supply pipe 4 can be cancelled, so as to improve the efficiency of quickly filling the rubber dam bag 2 with water;

[0039] Through the setting of the cleaning component 6, the impurities and stones filtered out by the filtering component 5 can be centrally managed, so as to improve the service life of the filtering component 5;

[0040] Through the setting of the drain pipe 7, the rubber dam bag 2 can be drained by opening the water valve inside the drain pipe 7.

[0041] Embodiment 2:

[0042] Embodiment 2 is used to further disclose the specific structure of the filtering component 5 on the premise of the above embodiment. By cooperating the filtering component 5 with the structure in the above embodiment, the setting that the filtering part can be adjusted internally is achieved. When in an emergency water filling state, the filtering part can be directly rotated inside the pipeline to be close to the inner wall of the pipeline, so as to avoid the filtering part blocking the inner wall of the pipeline, and thus improve the water filling efficiency.

[0043] A rubber dam water filling and draining device provided in Embodiment 1 is further optimized. Specifically, as Figures 4 - 7 shown, the filtering component 5 includes a filtering box 8, a first water pipe 9, and a second water pipe 10. The filtering box 8 is in clearance fit with the inner side of the reserved groove opened at the top of the dam foundation 1. One end of the outer side of the top of the filtering box 8 is fixedly connected to the first water pipe 9. The end of the first water pipe 9 away from the filtering box 8 is fixedly connected to the water inlet pipe 3 through a flange. The other end of the outer side of the top of the filtering box 8 is fixedly connected to the second water pipe 10. The end of the second water pipe 10 away from the filtering box 8 is fixedly connected to the water supply pipe 4 through a flange.

[0044] The filtering component 5 further includes a first rotating rod 14, a filtering plate 15, a second rotating rod 16, a transmission belt 17, a gear 18, and a first motor 19. Both sides of the inner side of the filtering box 8 are rotatably connected to the first rotating rod 14. Filtering plates 15 are fixedly connected to the sides of the two first rotating rods 14 close to each other. A first movable groove is opened at the top of the filtering box 8. The tops of the two first rotating rods 14 both extend into the inner side of the first movable groove. Second rotating rods 16 are rotatably connected to both sides of the central position of the inner side of the first movable groove. Transmission belts 17 are arranged on the outer sides of the second rotating rods 16 on the same side and the tops of the outer sides of the first rotating rods 14. And the second rotating rods 16 drive the first rotating rods 14 to rotate through the transmission belts 17. Gears 18 are fixedly connected to the outer sides of the second rotating rods 16. The two gears 18 are meshed. A first motor 19 is fixedly connected to the top of the filtering box 8. And the position of the first motor 19 corresponds to one of the second rotating rods 16. And the output end of the bottom of the first motor 19 extends into the inner side of the first movable groove and is fixedly connected to the top of the corresponding second rotating rod 16.

[0045] Specifically: when the two filtering plates 15 are adjusted to be perpendicular to the inner wall of the filtering box 8, the sides of the two filtering plates 15 close to each other are in a fitting state. At this time, the two filtering plates 15 can filter the water flow passing through the inner side of the filtering box 8.

[0046] When it is necessary to urgently fill water inside the rubber dam bag 2, by starting the first motor 19 and driving one of the second rotating rods 16 to rotate inside the first movable groove, the gear 18 fixedly connected to the outer side of the second rotating rod 16 can be driven to rotate synchronously. At the same time, through the meshing connection of the two gears 18, the other second rotating rod 16 can be driven to rotate in the reverse direction;

[0047] Through the transmission setting of the transmission belt 17, when the second rotating rod 16 rotates, the corresponding first rotating rod 14 can be driven to rotate synchronously, so that the filter plate 15 fixedly connected to the bottom of the first rotating rod 14 can be driven to rotate synchronously, and the two filter plates 15 can be rotated into a state parallel to the inner wall of the filter box 8, so that the water flow can pass through the inside of the filter box 8 conveniently. At the same time, when it is urgent to fill water inside the rubber dam bag 2, the cumbersome operation of disassembling the filtering part can be avoided, thereby improving the convenience of the filling and draining device.

[0048] Embodiment 3:

[0049] This Embodiment 3 further discloses the specific structure of the cleaning component 6 on the premise of the above embodiment. By cooperating the cleaning component 6 with the structure in the above embodiment, it can be achieved that by setting the cleaning component, the impurities and foreign matters in the filtering device can be effectively cleaned conveniently without disassembling the filtering device, and the filtering device can be prevented from being blocked by impurities or foreign matters and becoming ineffective, thereby improving the smoothness of the pipeline water filling. At the same time, the impurities and foreign matters generated by filtration can be automatically collected, so that the filtering device can be recycled without being blocked, thereby improving the service life of the filtering device and the entire filling and draining pipeline.

[0050] On the basis of Embodiment 1 and Embodiment 2, a rubber dam filling and draining device is further optimized. Specifically, as Figures 8 - 10 shown, the cleaning component 6 includes a plugging disc 11, a connecting rod 12 and a rotating plate 13. Plugging discs 11 are rotatably connected to the inside of the first water pipe 9 and the second water pipe 10 respectively. The plugging discs 11 play a plugging effect on the inside of the first water pipe 9 and the second water pipe 10. Connecting rods 12 are fixedly connected to the tops of the plugging discs 11 respectively. The tops of the connecting rods 12 extend to the outside of the tops of the first water pipe 9 and the second water pipe 10 respectively. Rotating plates 13 are fixedly connected to the outside of the connecting rods 12 located at the tops of the first water pipe 9 and the second water pipe 10.

[0051] The cleaning component 6 further includes a collection box 20, a fixed right-angle plate 21, a second motor 22, and a threaded rod 23. A second movable groove is formed at the bottom of the filter box 8, and a communication notch is formed at the top inside the second movable groove. The second movable groove is communicatively connected to the inside of the filter box 8 through the communication notch. The collection box 20 is in clearance fit with the inside of the second movable groove. An inlet groove is formed at the top of the collection box 20, and the position and size of the inlet groove are correspondingly set with the communication notch. The top of the filter box 8 is fixedly connected to the fixed right-angle plate 21, and the top of the fixed right-angle plate 21 is fixedly connected to the second motor 22. The output end at the bottom of the second motor 22 extends below the top of the fixed right-angle plate 21 and is fixedly connected to the threaded rod 23.

[0052] The cleaning component 6 further includes a movable push rod 24, a limiting strip 25, and a cleaning scraper 26. The movable push rod 24 is threadedly connected to the outer side of the bottom of the threaded rod 23. Limiting strips 25 are fixedly connected to both sides of the movable push rod 24. The movable push rod 24 and the limiting strips 25 penetrate through the inside of the first movable groove at the top of the filter box 8 and extend into the inside of the filter box 8. The movable push rod 24 and the limiting strips 25 are in clearance fit with the top of the filter box 8. The cleaning scraper 26 is fixedly connected to the bottom of the movable push rod 24 and the limiting strips 25 inside the filter box 8, and the cleaning scraper 26 is in contact with the surfaces of the two filter plates 15.

[0053] Specifically: when the two filter plates 15 filter the water flow, dirt and impurities in the water flow will remain on the surfaces of the filter plates 15;

[0054] By turning on the second motor 22, the threaded rod 23 can be driven to rotate at the bottom of the fixed right-angle plate 21, so that the movable push rod 24 threadedly connected to the outer side of the bottom of the threaded rod 23 can move up and down on the outer side of the threaded rod 23, and then the cleaning scraper 26 located inside the filter box 8 can be driven to move up and down synchronously through the connection of the movable push rod 24;

[0055] Through the setting of the limiting strip 25, the movable push rod 24 can maintain its own angle during the up and down movement, and the movable push rod 24 can move up and down stably;

[0056] Through the up and down movement of the cleaning scraper 26 inside the filter box 8, the surfaces of the two filter plates 15 can be scraped and cleaned, and the dirt and impurities on the surfaces of the filter plates 15 can be pushed into the inside of the communication notch and then into the collection box 20 inside the second movable groove for collection;

[0057] After a certain amount of impurities are collected inside the collection box 20, the collection box 20 can be taken out from the inside of the bottom of the filter box 8 and cleaned;

[0058] Before extracting the collection box 20, the rotating plate 13 can be rotated, and the connection setting of the connecting rod 12 drives the blocking disc 11 to block the inner sides of the first water pipe 9 and the second water pipe 10, so as to be able to cut off the water flow inside the filter box 8, and further facilitate the extraction and cleaning of the collection box 20.
