Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, and more specifically, to a device for emergency repair of ruptured sewage pipelines. Background Technology

[0002] The sewage pipeline system consists of pipes and their ancillary structures for collecting and transporting urban sewage. Sewage flows from branch pipes into main pipes, then into the main trunk, and finally into the sewage treatment plant. The pipes are distributed in a tree-like pattern, from small to large, which is completely different from the circulation of water supply networks. Sewage generally flows from high to low in the pipes due to the difference in water level at both ends. The pipes do not bear pressure and flow by gravity.

[0003] During municipal construction, pipes may be accidentally cracked. In cases where the leakage is not serious, the perforated pipe can be sealed with a sealing gasket and temporarily fixed with clamps to complete the temporary seal. After the construction is completed, the repair can be redone. However, the existing clamp repair technique is cumbersome in practice. To address the above problems, the following solution is proposed. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a sewage pipe rupture repair device, which can facilitate the rapid repair of sewage pipes.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A sewage pipe rupture repair device includes a sealing plate, which is arc-shaped. Two sealing plates are provided and arranged symmetrically. Sealing gaskets are provided on the inner sides of the two sealing plates respectively. The two sealing gaskets can be combined to form a complete ring. Pull ropes are symmetrically provided on the outer side of one of the sealing plates, and a locking component is provided on one side of the other sealing plate. The two pull ropes and the locking component are detachably connected.

[0007] Preferably, the locking assembly includes a locking frame, a threaded rod, and a movable plate. The locking frame is mounted on a corresponding sealing plate, the movable plate is slidably arranged inside the locking frame, the threaded rod is rotatably arranged inside the locking frame, the threaded rod passes through the movable plate, the threaded rod and the movable plate are threadedly engaged, and the pull rope and the movable plate are detachably engaged.

[0008] Preferably, the locking frame has symmetrical grooves on both sides, the grooves are parallel to the axis of the threaded rod, and a slider is slidably disposed inside the groove, the slider and the two ends of the movable plate are fixedly connected.

[0009] Preferably, pull rods are symmetrically arranged on both sides of the movable plate, and the two ends of the pull rods are fixedly connected to the sides of the movable plate through connecting frames. A bayonet is formed between the pull rods, the movable plate and the two connecting frames. One end of the pull rope is connected to a hook, and the hook engages with the bayonet.

[0010] Preferably, the arc of the sealing plate is less than 180 degrees, and buffer blocks are fixedly connected to both ends of the sealing plate, with the two sealing plates and corresponding buffer blocks forming a complete ring.

[0011] Preferably, a connecting rod is provided on one side of the locking frame. The connecting rod passes through one end of the locking frame and the threaded rod and is fixedly connected. The connecting rod and the locking frame are rotatably engaged. An adjustment port is provided at the end of the connecting rod away from the threaded rod.

[0012] Preferably, the pull rope is made of steel wire.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This solution uses sealing gaskets to seal external cracks in the pipe. Two sealing gaskets can be combined to form a complete ring, thus providing a comprehensive seal to the outside of the pipe. Two sealing plates fix and protect the sealing gaskets. Two pull ropes and locking components work together to ensure that there is room for movement between the two sealing plates, thereby ensuring the friction between the sealing gaskets and the pipe surface and ensuring the sealing effect. The use of locking components and pull ropes facilitates installation and disassembly.

[0015] Second, the moving plate is driven by the threaded rod, and the moving plate drives one end of the pull rope to move, thereby increasing the pressure between the two sealing plates.

[0016] Third, the combination of the slide and the slider is used to limit the movement of the moving plate. On the one hand, it can make the moving plate slide stably, and on the other hand, it can prevent the moving plate from rotating.

[0017] Fourth, the pull rod, the movable plate, and the two connecting brackets form a bayonet and hook fit, which facilitates the connection of the pull rope and the locking component.

[0018] 5. The curvature of the sealing plate is less than 180 degrees to ensure that there is a movement distance between the two sealing plates. Buffer rubber blocks are used, which are elastic to ensure the distance between the sealing plates and at the same time, they can contact each other to increase friction.

[0019] 6. The adjustment port is used to facilitate the rotation of the connecting rod, which in turn drives the threaded rod to rotate.

[0020] 7. The steel wire is strong and will not deform, ensuring stable fixation. Attached Figure Description

[0029] Example 1:

[0030] Please see Figure 1-6 A sewage pipe rupture repair device includes two sealing plates 1 arranged symmetrically. Each sealing plate 1 is arc-shaped with an arc angle less than 180 degrees. Buffer blocks 13 are fixedly connected to both ends of each sealing plate 1. The two sealing plates 1 and corresponding buffer blocks 13 form a complete ring. Sealing gaskets 2 are provided on the inner surfaces of the two sealing plates 1. The sealing gaskets 2 and buffer blocks 13 are integrally formed. The two sealing gaskets 2 can be combined to form a complete ring. The sealing gaskets 2 seal the external rupture of the pipe. The two sealing gaskets 2 can be combined to form a complete ring, thus providing all-around sealing of the pipe's exterior. The two sealing plates 1 fix and protect the sealing gaskets 2. The arc angle of the sealing plates 1 is less than 180 degrees, ensuring a movement distance between the two sealing plates 1. The buffer blocks 13 are elastic, maintaining the distance between the sealing plates 1 while also allowing them to contact each other to increase friction.

[0031] One of the sealing plates 1 has symmetrically arranged pull ropes 3 on its outer side. The pull ropes 3 are made of steel wire, which has the advantages of being strong and not deforming, ensuring stable fixation. The other sealing plate 1 has a locking assembly 4 on one side. The two pull ropes 3 and the locking assembly 4 are detachably connected. The locking assembly 4 includes a locking frame 5, a threaded rod 6, and a movable plate 7. The locking frame 5 is installed on the corresponding sealing plate 1. The movable plate 7 is slidably arranged inside the locking frame 5. The locking frame 5 has symmetrically arranged sliding grooves 8 on both sides, with the orientation of the sliding grooves 8 parallel to the axis of the threaded rod 6. A slider 9 is slidably arranged inside the sliding groove 8, and the slider 9 is fixedly connected to both ends of the movable plate 7. The threaded rod 6 is rotatably arranged inside the locking frame 5, locking... A connecting rod 14 is provided on one side of the frame 5. The connecting rod 14 passes through the locking frame 5 and is fixedly connected to one end of the threaded rod 6. The connecting rod 14 and the locking frame 5 are rotatably engaged. An adjustment port 15 is provided at the end of the connecting rod 14 away from the threaded rod 6. The adjustment port 15 is hexagonal and can be adjusted with a suitable Allen wrench. The threaded rod 6 passes through the movable plate 7. The threaded rod 6 and the movable plate 7 are threadedly engaged. Pull rods 10 are symmetrically provided on both sides of the movable plate 7. The two ends of the pull rods 10 are fixedly connected to the sides of the movable plate 7 through the connecting frame 11. A bayonet 12 is formed between the pull rods 10, the movable plate 7 and the two connecting frames 11. A hook 16 is connected to one end of the pull rope 3. The hook 16 is engaged with the bayonet 12.

[0032] A bayonet 12 and a hook 16 are formed between the pull rod 10, the movable plate 7 and the two connecting brackets 11 to facilitate the connection between the pull rope 3 and the pull rod 10. The movable plate 7 is moved by the threaded rod 6, and one end of the pull rope 3 is moved by the movable plate 7, thereby increasing the pressure between the two sealing plates 1.

[0033] Working principle:

[0034] Two sealing plates 1 are wrapped around the outside of the pipe, and sealing gaskets 2 are used to seal the cracks on the outside of the pipe. Two hooks 16 and two pull rods 10 are connected. An Allen wrench is used to turn the adjustment port 15, which drives the connecting rod 14 to rotate. The connecting rod 14 drives the threaded rod 6 to rotate. Since the threaded rod 6 and the moving plate 7 are threaded together, the rotating threaded rod 6 drives the moving plate 7 to move upward. The moving plate 7 drives the connecting frame 11 to move, the connecting frame 11 drives the pull rod 10 to move, and the pull rod 10 drives the hooks 16 to move. The hooks 16 will cause the pull rope 3 to taut, thereby bringing the distance between the two sealing plates 1 closer. The pressure between the two sealing plates 1 is applied to the sealing gasket 2, so that the sealing gasket 2 adheres to the pipe. The sealing gasket 2 seals the crack in the pipe, preventing liquid leakage, thus completing the emergency repair of the pipe.
