Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-8 , the present utility model provides the following technical solutions.

[0033] Embodiment 1: To solve the problem of poor sealing performance during the plugging process in the prior art, therefore, in this embodiment, through the following technical solutions, an internally filled expandable and quickly opened underwater pipeline emergency plugging device is provided, which is provided with a fixed plate 1, an auxiliary rod 2, and an internally filled expandable and quickly opened airbag 3. The fixed plate 1 is connected to the internally filled expandable and quickly opened airbag 3 through the auxiliary rod 2. As Figure 1 and Figure 2 shown, the operator drives the internally filled expandable and quickly opened airbag 3 through the auxiliary rod 2 to place the fixed plate 1 in the pipeline to be plugged. Through the internal inflation and rapid expansion of the internally filled expandable and quickly opened airbag 3, it can be tightly attached to the inner wall of the pipeline, effectively plugging the pipeline with better sealing performance.

[0034] Embodiment 2: For the existing underwater pipeline emergency plugging device with internal filling and rapid expansion opening, it is inconvenient to store the device. Therefore, by setting the movable plate 4, positioning column 5, fixed frame 6, fixed block 7, auxiliary block 8, spring 9, fixed pin 10, pull rod 11 and limit column 12, a positioning column 5 is fixedly connected to the side of the movable plate 4 near one end of the fixed plate 1, and the positioning column 5 is connected to the fixed plate 1 through a card slot. A fixed block 7 is fixedly connected to the left end of the fixed plate 1. The movable plate 4 and the fixed plate 1 are hinged, and a torsion spring is arranged at the connection between the movable plate 4 and the fixed plate 1. The rotation angle range between the movable plate 4 and the fixed plate 1 is 0 - 90°, and the movable plates 4 are arranged at equal angles outside the fixed plate 1. An auxiliary block 8 is fixedly connected to the side of the fixed frame 6, and a spring 9 is arranged inside the auxiliary block 8. The movable end of the spring 9 is fixedly connected to a fixed pin 10. The fixed pin 10 is telescopically connected to the middle of the auxiliary block 8, and the fixed pin 10 is fixedly connected to the pull rod 11. The pull rod 11 and the auxiliary block 8 form a sliding structure. The fixed pin 10 is inserted into the middle of the limit column 12, and the limit column 12 is fixedly connected to the edge of the left end of the fixed plate 1. As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 , after the internal filling and rapid expansion airbag 3 plugs the pipeline, the movable plate 4 is flipped. The movable plate 4 rotates with the fixed plate 1, and the torsion spring at the connection between the movable plate 4 and the fixed plate 1 undergoes elastic deformation. The movable plate 4 drives the positioning column 5 to be connected to the fixed plate 1 through a card slot, so that the state of the movable plate 4 and the positioning column 5 changes from the state shown in Figure 8 to the state shown in Figure 1 . At this time, the movable plate 4 drives the positioning column 5 to penetrate through the middle of the fixed frame 6. Then, by pressing the pull rod 11, the pull rod 11 drives the fixed pin 10 to slide in the middle of the auxiliary block 8, and the fixed pin 10 squeezes the spring 9, causing the spring 9 to undergo elastic deformation. Then, the fixed frame 6 is pulled towards the side close to the horizontal central axis of the fixed plate 1, and the fixed frame 6 slides with the fixed block 7, so that the fixed frame 6 and the positioning column 5 are in a fitting arrangement, thus facilitating the limitation of the positioning column 5 and fixing between the movable plate 4 and the fixed plate 1. At this time, the fixed pin 10 aligns with the limit column 12, and then the pull rod 11 is directly released. At this time, the spring 9 restores its elastic deformation, pushing the fixed pin 10 to slide with the auxiliary block 8, so that the fixed pin 10 is inserted into the middle of the limit column 12, further facilitating the limitation between the fixed frame 6 and the fixed block 7. In addition, after use, the above operations can be reversed, and the movable plate 4 can be flipped to the state shown in Figure 8 , so as to facilitate the folding and storage of the device, which is convenient for storage and recycling.

[0035] Embodiment 3: For the existing underwater pipeline emergency plugging device with internal filling and rapid expansion opening, which is sealed only by an airbag, the actual fastening property is not good, and it is inconvenient to reinforce between the airbag and the pipeline. Therefore, by setting the connecting mechanism 13 and the clamping plate 18, the connecting mechanism 13 includes a fixing rod 14 fixedly connected to the middle of the movable plate 4, a fixing sleeve 15 for limiting, a connecting plate 16 sleeved on the outer surface of the fixing rod 14, and a mounting rod 17 fixedly connected to the side of the connecting plate 16. The fixing sleeve 15 is connected to the fixing rod 14 by a threaded manner, and the fixing sleeve 15 is in a fitting setting with the connecting plate 16. A sliding structure is formed between the connecting plate 16 and the fixing rod 14, and the connecting plate 16 drives the mounting rod 17 to form a sliding structure with the movable plate 4. The mounting rod 17 and the clamping plate 18 are installed and fixed by bolts. As Figure 1 , Figure 2 , Figure 4 and Figure 7 shown, the mounting rod 17 and the clamping plate 18 are installed and fixed by bolts. Then, by rotating the fixing sleeve 15 threadedly connected to the outer surface of the fixing rod 14, the fixing sleeve 15 pushes the connecting plate 16 to slide between the fixing rod 14, so that the connecting plate 16 drives the mounting rod 17 to slide with the movable plate 4, and further drives the clamping plate 18 to support and fix on the inner wall of the pipeline to be plugged, thereby facilitating the reinforcement and support of the device, improving the stability of the whole device during the plugging process, and preventing detachment.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
