[0013] This utility model provides an emergency sealing device for sewage pipelines, which has the following beneficial effects: 1. This application utilizes a reinforcement mechanism. A waterproof motor drives a screw to rotate, which is screwed to a movable cylinder. As the screw rotates, the movable cylinder moves, causing the connecting seat to move. This, in turn, causes the connecting rod to deflect and unfold, moving the mounting seats away from each other. This, in turn, causes the movable rod to move, which in turn moves the support block, allowing the support block to fit against the pipe sidewall, thus reinforcing the airbag and securing it firmly in the sewage pipe. This prevents the airbag from being washed away by water flow, allowing for long-term placement in a designated location and improving sealing quality.

[0014] 2. This application utilizes a placement mechanism where pulling the pull plate moves the extension rod, causing the slot to press against the inclined surface of the block, retracting the block inside the mounting housing. This, in turn, moves the moving plate, compressing a powerful spring. When the block aligns with the slot, the spring resets, embedding the block within the slot. This allows for easy adjustment of the extension rod's position based on the depth of the sewage well. The connection between the connecting pipe and the extension rod facilitates placement of the airbag body into the sewage pipe, preventing manual placement and reducing safety hazards.

[0017] This utility model provides an emergency sealing device for sewage pipelines.

[0018] Example 1: An emergency sealing device for sewage pipes includes an airbag body 1, a hanging ring 2 fixed to one side of the airbag body 1, an air nozzle 3 fixed to one side of the airbag body 1, a counterweight 4 placed inside the airbag body 1, a sleeve 5 fixed to the middle of one side of the airbag body 1, and a reinforcement mechanism 6 provided on the outside of the sleeve 5.

[0019] Please refer to it again. Figure 2 and Figure 3The reinforcement mechanism 6 includes a housing 601 symmetrically fixed to the outer wall of the sleeve 5. A movable rod 602 slides through the middle of one side of the housing 601. A support block 603 is fixed to one end of the movable rod 602. A mounting base 604 is fixed to one side of the movable rod 602. A connecting rod 605 rotates inside the mounting base 604. An mounting cylinder 606 is fixed to the side of the inner wall of the sleeve 5. A waterproof motor 607, model SF86H48V-15, is fixed to the middle of one side of the inner cavity of the mounting cylinder 606. 6. A screw 608 is fixed to the end of the output shaft of the waterproof motor 607. A movable cylinder 609 is screwed to the outer wall of the screw 608. A connecting seat 610 is symmetrically fixed to the outer side of the movable cylinder 609. A through groove is opened through the middle of one side of the housing 601, and the mounting seat 604 is located inside the through groove. One end of the connecting rod 605 rotates inside the connecting seat 610. A baffle is fixed to one end of the movable rod 602, and the baffle is located inside the housing 601. A connecting rod 605 is symmetrically opened through the outer side of the sleeve 5. A groove is formed, and the connecting seat 610 is located inside the groove; the movable cylinder 609 passes through the middle of one side of the mounting cylinder 606, and a sealing ring is provided between the movable cylinder 609 and the mounting cylinder 606; the connecting wire of the waterproof motor 607 passes through the outside of the mounting cylinder 606 and the sleeve 5, and a sealant is provided between the connecting wire and the mounting cylinder 606; through the setting of the reinforcing mechanism 6, the starting of the waterproof motor 607 drives the screw 608 to rotate, and the screw 608 is screwed to the movable cylinder 609. When the cylinder 609 rotates, it moves the movable cylinder 609, which in turn moves the connecting seat 610, causing the connecting rod 605 to deflect and unfold. This causes the mounting seats 604 to move away from each other, which in turn moves the movable rod 602, causing the support block 603 to move. This allows the support block 603 to fit against the side wall of the pipe, completing the support and fixing, thereby reinforcing the airbag and making it stable in the sewage pipe. This prevents the airbag from being washed away by the water flow, making it easy to place in a designated position for a long time and improving the sealing quality.

[0020] Example 2: Please refer to it again. Figure 4 and Figure 5One end of the sleeve 5 is bolted to a placement mechanism 7. The placement mechanism 7 includes a connecting pipe 701 bolted to one end of the sleeve 5. A mounting shell 702 is fixed to the top of the connecting pipe 701. A strong spring 703 is fixed to the middle of one side of the inner cavity of the mounting shell 702. A moving plate 704 is fixed to one end of the strong spring 703. A locking block 705 is fixed to the middle of one side of the moving plate 704. A pull rod 706 is fixed to the middle of the other side of the moving plate 704. A sliding plate 707 slides inside the connecting pipe 701. An extension rod 708 is fixed to the middle of the top of the sliding plate 707. The outer side wall of the extension rod 708 is evenly provided with locking grooves 709. A pull plate 710 is fixed to the top of the extension rod 708. The placement mechanism 7 includes a limiting groove 711 opened on the outer side wall of the sliding plate 707. Limiting strips 712 are symmetrically fixed to the inner side wall of the connecting pipe 701. A fastening bolt 713 is threaded through the top of the outer side wall of the connecting pipe 701. The limiting strip 712 is located inside the limiting groove 711, the moving plate 704 slides inside the mounting shell 702, the pull rod 706 passes through one side of the mounting shell 702, and the bottom of the slot 709 and the bottom of the block 705 are both provided with inclined surfaces. Through the setting of the placement mechanism 7, by pulling the pull plate 710, the extension rod 708 is moved, so that the slot 709 squeezes the inclined surface of the block 705, causing the block 705 to retract into the mounting shell 702, which drives the moving plate 704 to move and squeeze the strong spring 703. When the block 705 is aligned with the slot 709, the strong spring 703 resets, so that the block 705 is embedded in the slot 709, which facilitates the adjustment of the position of the extension rod 708 and the adjustment according to the depth of the sewage well. With the cooperation of the connecting pipe 701 and the extension rod 708, it is easy to place the airbag body 1 in the sewage pipe, preventing manual placement in the well and reducing safety hazards.

[0021] When using this utility model: Working principle: Connect the electrical components to an external power source and control switch. Connect the external connecting rope to the hanging ring 2. Simultaneously, connect the external air source to the air nozzle 3 through the air pipe. Pull the pull plate 710, which moves the extension rod 708. This causes the slot 709 to press against the inclined surface of the locking block 705, causing the locking block 705 to retract into the mounting shell 702. This moves the moving plate 704, which presses against the strong spring 703. When the locking block 705 aligns with the slot 709, the strong spring 703 resets, allowing the locking block 705 to be embedded in the slot 709. This facilitates adjustment of the position of the extension rod 708 according to the depth of the sewage well. Then, the airbag... The airbag body 1 is placed in the sewage pipe, and the connecting rope is tied to the outside. The air source is connected, and the airbag body 1 is inflated to seal the sewage pipe. Then, the waterproof motor 607 is started. The start of the waterproof motor 607 drives the screw 608 to rotate. The screw 608 is screwed to the moving cylinder 609. When the screw 608 rotates, the moving cylinder 609 moves, thereby driving the connecting seat 610 to move. This causes the connecting rod 605 to deflect and unfold, thereby causing the mounting seats 604 to move away from each other. This causes the moving rod 602 to move, driving the support block 603 to move, so that the support block 603 fits against the side wall of the pipe, completing the support and fixation.
