Description
Technical Field
[0001] This utility model relates to the field of flood control technology, specifically to an adaptive sealing connector for prefabricated flood walls. Background Technology
[0002] Traditional flood control facilities often suffer from long construction periods, high construction difficulty, and insufficient flexibility, making them ineffective in responding to sudden flood threats. Against this backdrop, prefabricated flood walls have emerged. Prefabricated flood walls are modular flood control facilities that can be assembled quickly. They have advantages such as fast construction speed, reusability, and strong adaptability, which can effectively improve flood emergency response capabilities and reduce losses caused by floods. As a key component of prefabricated flood walls, connectors are used to firmly splice the various prefabricated flood wall modules together to prevent flood leakage and ensure the structural stability and sealing of the entire flood wall system. Thus, they can effectively block flood intrusion when floods occur, protecting people's lives and property.
[0003] In emergency situations, the rapid construction of flood walls is often constrained by time and site conditions, leaving insufficient time for distance measurement and installation. This results in inconsistent spacing between the constructed flood walls. However, most existing flood wall connectors are fixed-size structures, which are difficult to adapt to the connection requirements of different spacings. This not only makes it difficult to connect the flood walls but may also make it difficult to guarantee the sealing of the connection points, thereby affecting the reliability and integrity of the entire flood control system. Therefore, based on the above problems, a prefabricated flood wall adaptive sealing connector is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide an adaptive sealing connector for prefabricated flood walls, so as to solve the problem that existing connectors are difficult to adapt to the connection requirements of different spacings of various flood walls. This not only brings difficulties to the connection between flood walls, but may also lead to the problem that the sealing performance of the connection is difficult to guarantee.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An adaptive sealing connector for prefabricated flood control walls includes a frame, a roller, an venting section, a waterproof roll, an elastic bladder, a connecting section, and a positioning section. The frame includes a frame body with a longitudinally penetrating rotating hole on its upper inner side and an installation opening on its front side. A roller is mounted on the frame body, and the roller includes a roller shell rotatably connected to the rotating hole.

[0009] Preferably, the waterproof rolls are all wound on the outside of the roller shell, the waterproof rolls are all disposed on the inside of the frame, and the lowest point of the elastic band is higher than the lower end face of the roller shell.
[0010] Preferably, the piston block is disposed on the upper side of the venting groove and the air inlet hole. The diameter of the piston block is the same as the inner diameter of the roller shell. The outer end face of the piston block is in contact with the inner wall of the roller shell. A convex ring is provided on the upper outer side of the roller shell.

[0030] Please see Figure 1-8 This utility model provides a technical solution:
[0031] An adaptive sealing connector for a prefabricated flood control wall includes a frame 1, a roller 2, an exhaust 3, a waterproof roll 4, an elastic bladder 5, a connecting part 6, and a positioning part 7. The frame 1 includes a frame body 11, with a longitudinally penetrating rotating hole 12 on the upper inner side of the frame body 11 and an installation opening 13 on the front side of the frame body 11. The roller 2 is installed at the frame body 11. The roller 2 includes a roller shell 21 rotatably connected to the rotating hole 12. Connecting strips 22 are fixedly connected to both the front and rear sides of the roller shell 21. Ventilation grooves 23 communicating with the roller shell 21 are opened on the lower inner side of each connecting strip 22. An air inlet 24 is opened on the left side of the rear ventilation groove 23, and an air outlet 24 is opened on the right side of the front ventilation groove 23. An air inlet 24 is provided, and an exhaust part 3 is installed at the roller shell 21. The exhaust part 3 includes a piston rod 31 that is slidably connected to the upper hole of the roller shell 21. A linkage bar 32 is fixedly connected to the upper end of the piston rod 31, and a control handle 33 located on the front side of the frame 11 is fixedly connected to the lower end of the linkage bar 32. A piston block 34 located on the inner side of the roller shell 21 is fixedly connected to the lower end of the piston rod 31. Waterproof rolls 4 are fixedly connected to the outer sides of the front and rear connecting bars 22. An elastic bladder 5 communicating with the air inlet 24 is fixedly connected to the lower side of the waterproof rolls 4. A connecting part 6 is fixedly connected to the end of the waterproof rolls 4 away from the roller shell 21, and the connecting parts 6 are all located on the left and right sides of the frame 1.
[0032] The connecting part 6 includes a mating frame 61 that fits against the outer end face of the frame 11. A vent pipe 62, communicating with the elastic band 5, is installed in the lower inner channel of the mating frame 61. One end of the vent pipe 62, away from the elastic band 5, is connected to an elastic fold 63, which is fixedly connected to the inner wall of the base frame 71. This arrangement allows the connecting part 6 to communicate with the elastic band 5. A damping pad 64 is fixedly connected to the inner wall of the elastic band 5, which improves the connection strength of the connecting part 6. The base frame 71, the elastic band 5, and the damping pad 64 are all U-shaped structures. The components 4 are arranged in a multi-layered nested configuration; the waterproof rolls 4 are all wound on the outside of the roller shell 21, and the waterproof rolls 4 are all set on the inside of the frame 11. This configuration allows for the storage of the waterproof rolls 4. The lowest point of the elastic bladder 5 is higher than the lower end face of the roller shell 21. This configuration ensures that the elastic bladder 5 will not contact the ground when it moves with the waterproof rolls 4. The piston block 34 is set above the venting groove 23 and the air inlet 24. The diameter of the piston block 34 is the same as the inner diameter of the roller shell 21. The outer end face of the piston block 34 is in contact with the inner wall of the roller shell 21. This configuration allows the air under the piston block 34 to be released when it moves downward. As the body is pushed down, a convex ring is provided on the upper outer side of the roller shell 21. The convex ring of the roller shell 21 is rotatably connected to the annular groove of the rotating hole 12. This arrangement ensures that the roller shell 21 is always rotatably connected to the rotating hole 12. A positioning part 7 is installed on the inner side of the mounting port 13. The positioning part 7 includes a base frame 71 fixedly connected to the inner wall of the mounting port 13. A pressure guide block 72 is slidably connected to the inner side of the base frame 71. A guide rail 73 is provided on the inner side of the pressure guide block 72. A base block 74 is provided on the inner side of the guide rail 73 and fixedly connected to the inner wall of the base frame 71. A spring 75 is fixedly connected between the front end face of the base block 74 and the front inner wall of the guide rail 73. A spring is fixedly connected to the rear side of the pressure guide block 72. The elastic damping block 76, through the positioning part 7, can position the roller 2 and the waterproof roll 4 that may not be fully unwound, preventing the waterproof roll 4 from being further unwound; the positioning part 7 is located on the front side of the roller 2, and through this setting, the rearward movement of the elastic damping block 76 of the positioning part 7 can position the roller 2; the pressure guide block 72 protrudes from the front end face of the frame 11, and the pressure guide block 72 is located directly below the control handle 33, and through this setting, the downward movement of the control handle 33 can apply pressure to the pressure guide block 72 and push it back; the rear end face of the vertical plate of the linkage bar 32 is in contact with the front end face of the frame 11, and through this setting, the exhaust part 3 can only move up and down.
[0033] Workflow: The operation procedure for using the adaptive sealing connector for flood wall connection is as follows: First, complete the construction of each flood wall. Then, precisely move the connector of this application to the spacing between each flood wall. At this time, the operator can pull the connecting parts 6 on both sides to move them in opposite directions, so that the mating frame 61 of the connecting part 6 fits onto the outside of the flood wall. As the connecting parts 6 on both sides move, the waterproof roll 4 wound on the outside of the roller shell 21 will be pulled out from the frame 11, simultaneously driving the roller shell 21 to rotate, thus realizing the waterproof roll... As the waterproof roll 4 is unwound, the elastic bladder 5 connected to it will also shift. After completing the above preparations, the operator holds the control handle 33 and pulls down the linkage bar 32, piston rod 31, and piston block 34. The downward movement of the piston block 34 will release the gas under the piston block 34 into each elastic bladder 5 through the vent groove 23 and the air inlet 24. Subsequently, some gas will be further transported to the elastic fold 63 through the vent pipe 62. This operation will cause each elastic fold 63 and elastic bladder 5 to move together. The system inflates and unfolds, with the elastic bladder 5 expanding to fit tightly against the ground, effectively preventing subsequent flood leakage from the bottom. Meanwhile, the expansion of the elastic folding bladder 63, in conjunction with the damping pad 64, allows for a tight fit and locking against the flood control wall, ensuring both connection stability and reliable sealing. Furthermore, the downward movement of the control handle 33 and the connecting frame 32 applies pressure to the pressure guide block 72, causing it to move the elastic damping block 76 backward, positioning the roller 2 and any potentially incompletely unwound waterproof roll 4. To prevent the waterproof roll 4 from being further unwound, the vertical plate of the connecting frame 32 abuts against the front of the pressure guide block 72 to position the pressure guide block 72 and the elastic damping block 76. The connection operation is completed through the above steps. This realizes that the adaptive sealing connector can adapt to the connection requirements of different spacings of various flood walls and ensures the sealing performance. It solves the problem that the existing connector is difficult to adapt to the connection requirements of different spacings of various flood walls, which not only brings difficulties to the connection between flood walls, but may also lead to the problem that the sealing performance of the connection is difficult to guarantee.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
