Description

Technical Field

[0001] This utility model relates to the field of rubber dam bag technology, and in particular to an emergency sealing device for damaged rubber dam bags. Background Technology

[0002] Rubber dam bags are a new type of hydraulic structure that expands to form a water-retaining dam by filling them with water (or air). However, during use, rubber dam bags are often punctured by floating debris or sharp objects carried downstream. Damaged rubber dam bags have a significantly reduced water-retaining effect. If not repaired in time, they may eventually tear and collapse, failing to properly retain and store water. The water intercepted in the river will then overflow, causing flooding disasters along the downstream banks of the project.

[0003] The authorized announcement number “CN219568729U” discloses an emergency sealing device for damaged rubber dam bags, which states that: “Since the area of ​​the sealing plate is necessarily larger than the area of ​​the hole, in actual use, it is not convenient to put the bottom sealing plate into the rubber dam bag, and it is necessary to enlarge the hole when necessary, which increases the workload.”

[0004] In the process of implementing this patent, the applicant discovered the following technical problems:

[0005] The sealing device described in this patent uses two airbags to clamp and seal the opening of the rubber dam bag. Because the airbags are flexible and elastic, they expand along the normal direction after inflation, making it difficult to fit snugly around the damaged area. This affects the sealing effect. Furthermore, the device requires a long inflation time and the airbags need to be moved closer together after inflation, making the operation cumbersome and reducing the efficiency of sealing the rubber dam bag. Therefore, an emergency sealing device for damaged rubber dam bags is needed to address the technical problems mentioned in the patent and provide a new technical solution. Utility Model Content

[0006] Based on this, an emergency sealing device for damaged rubber dam bags is provided to solve the following technical problems mentioned in the background art: Since the sealing device set in this patent uses two airbags to clamp and seal the opening of the rubber dam bag, and because the airbags themselves are soft and elastic, they will expand along the normal direction after inflation, making it difficult to fit around the damaged area of ​​the dam bag. Therefore, it will have a certain impact on the sealing effect of the damaged area of ​​the rubber dam bag. At the same time, the inflation time of this device is relatively long when sealing, and after inflation, it is necessary to move the airbags closer to each other, which is cumbersome and reduces the efficiency of sealing the rubber dam bag.

[0048] The sealing assembly 2 also includes a protective sleeve 22, a second screw 23, a second gear 24, a first fixing block 25, a rotating shaft 26, a guide rod 27, and a second fixing block 28. Protective sleeves 22 are fixedly connected to the outer sides of both ends of the hollow column 1. A gap is left between the bottom of the protective sleeve 22 and the hollow column 1. A second screw 23 is provided inside one of the protective sleeves 22. The top of the second screw 23 is rotatably connected to the inner side of the fixing plate 4, and the top of the second screw 23 extends to the top of the fixing plate 4. A second gear 24 is fixedly connected to the outer side of the second screw 23 at the top of the fixing plate 4, and the second gear 24 is meshed with the first gear 7.

A guide rod 27 is provided inside the other protective sleeve 22. The top of the guide rod 27 is fixedly connected to the bottom of the fixing disk 4, and the bottom of the guide rod 27 is clearance-fitted to the inner side of the second sliding disk 14. A second fixing block 28 is fixedly connected to the outer side of the bottom of the sliding cylinder 13. The second fixing block 28 is located below the second sliding disk 14 and its position corresponds to the guide rod 27. The inner side of the second fixing block 28 is clearance-fitted to the guide rod 27.

[0049] Specifically: After the lower half of the hollow column 1 is inserted into the rubber dam bag, the first sliding plate 11 and the second fixing rod 12 are both located inside the rubber dam bag;

[0050] Then, by rotating the rotating disk 5, the connecting rod 6 can be driven to rotate inside the fixed disk 4, thereby driving the first screw 8, which is fixedly connected to the connecting rod 6, to rotate synchronously inside the hollow column 1.

[0051] With the top and bottom of the first screw 8 being symmetrically arranged, the first fixed rod 10 and the second fixed rod 12 can be driven to move synchronously and in opposite directions inside the hollow column 1, and at the same time, the extrusion plate 9 and multiple first sliding discs 11 can be driven to move synchronously and in opposite directions.

[0052] While the first sliding disc 11 moves upward, it can drive the sliding cylinder 13 to move synchronously on the outer side of the bottom of the hollow column 1, thereby driving the multiple extrusion blocks 17 located on the outer side of the first sliding disc 11 to move synchronously. At the same time, the gap between the bottom of the protective sleeve 22 and the hollow column 1 can prevent the protective sleeve 22 from blocking the upward movement of the sliding cylinder 13.

[0053] When the first sliding disc 11 and the extrusion sheet 9 are in a close fit and clamp the gap of the rubber dam bag, the multiple extrusion blocks 17 at the top of the first support rod 16 will be in a synchronous fit with the bottom of the extrusion sheet 9. By setting the right angle position of the top of the first support rod 16 on the inner side of the bottom of the extrusion block 17, it can provide partial support for the bottom of the extrusion block 17. Thus, while the top of the extrusion block 17 and the top of the first support rod 16 are rotatably connected, the extrusion block 17 is kept at an upward angle, which makes it easier for the top of the extrusion block 17 and the bottom of the extrusion sheet 9 to clamp the gap of the rubber dam bag.

[0054] While rotating the connecting rod 6, the first gear 7 on the outside of the connecting rod 6 can be driven to rotate synchronously, thereby driving the second gear 24 meshing with the first gear 7 to rotate synchronously, thereby driving the second screw 23 fixedly connected to the second gear 24 to rotate synchronously, thereby driving the second sliding disk 14 threadedly connected to the second screw 23 to move upward on the outside of the sliding cylinder 13.

[0055] Meanwhile, the guide rod 27 can support and stabilize the up-and-down movement of the second sliding disc 14 on the outside of the sliding cylinder 13.

[0056] The protective sleeve 22 can protect the second screw 23 and the guide rod 27.

[0057] While the first sliding disc 11 drives the sliding cylinder 13 to move upward, it can also drive the first fixed block 25 and the second fixed block 28, which are fixedly connected to the bottom of the sliding cylinder 13, to move upward synchronously. By setting the rotating shaft 26 rotatably connected to the inner side of the first fixed block 25, it can be achieved that the rotation effect of the second screw 23 will not be affected while the first fixed block 25 moves upward.

[0058] After the second sliding disc 14 moves upward outside the sliding cylinder 13, it can drive multiple first rotating seats 15 on the outside of the second sliding disc 14 to move upward synchronously. This can drive the first support rod 16, which is rotatably connected to the outside of the first rotating seat 15, to move upward synchronously. At the same time, through the support effect of the second support rod 19, the third support rod 20 and the extension rod 21, the first support rod 16 can be flipped while the first rotating seat 15 moves upward. This causes the first support rod 16 to drive the top extrusion block 17 to move away from the sliding cylinder 13, thereby expanding the support range formed by the multiple extrusion blocks 17 and increasing the sealing area of ​​the rubber dam bag at the damaged location.

[0059] Meanwhile, the sliding connection between the second support rod 19, the third support rod 20, and the extension rod 21 allows the lengths of the second support rod 19, the third support rod 20, and the extension rod 21 to be adaptively adjusted according to the flipping angle of the first support rod 16.

[0060] Example 3:

[0061] This embodiment 3 further discloses the specific structure of the limiting component 3 based on the above embodiments. By cooperating with the structure in the above embodiments, the limiting component 3 can prevent the subsequent clamping position from becoming loose by setting a limit on the rotation position, thereby improving the stability of the sealing device in clamping and sealing the gaps of the rubber dam bag.

[0062] The emergency sealing device for damaged rubber dam bags provided in Embodiment 1 and Embodiment 2 has been further optimized, specifically, as follows: Figure 11As shown, the limiting component 3 includes a third fixing rod 29, a fixing plate 30, a sliding plate 31, a spring 32, and an insert rod 33. Multiple first limiting grooves are provided on the inner side of the rotating disk 5, and two second limiting grooves are provided on the top of the fixing disk 4. The size of the second limiting grooves corresponds to the size of the first limiting grooves. A third fixing rod 29 is fixedly connected to one end of the top of the fixing disk 4. A fixing plate 30 is fixedly connected to the top of the third fixing rod 29. A sliding plate 31 is fitted to the outer side of the third fixing rod 29 with clearance. A spring 32 is provided on the outer side of the third fixing rod 29, located between the sliding plate 31 and the fixing plate 30. The top and bottom of the spring 32 are fixedly connected to the fixing plate 30 and the sliding plate 31, respectively. One end of the sliding plate 31 away from the third fixing rod 29 extends above the rotating disk 5. Insert rods 33 are fixedly connected to both sides of the bottom of the sliding plate 31 above the rotating disk 5. The insert rods 33 are inserted into and limited by the first and second limiting grooves.

[0063] Specifically: by moving the sliding piece 31 upward, the two insert rods 33 at the bottom of the sliding piece 31 can be moved to the top of the rotating disk 5, thereby canceling the insertion and limiting cooperation of the insert rods 33 with the first limiting groove on the inner side of the rotating disk 5, and thus enabling the rotating disk 5 to rotate.

[0064] As the sliding piece 31 moves upward, it can compress the spring 32.

[0065] After the rotating disk 5 rotates to a certain extent, it can drive the sliding piece 31 to insert downwards, and the sliding piece 31 is inserted into the second limiting groove opened on the top of the fixed disk 4 through the first limiting groove on the inner side of the rotating disk 5, thereby limiting the position of the rotating disk 5. At the same time, through the elastic setting of the spring 32, it can continuously push the sliding piece 31 downwards, thereby maintaining the limiting effect of the insertion rod 33 on the rotating disk 5.
