Description

Technical Field

[0001] This utility model relates to the field of drainage pipe sealing technology, and in particular to a rapid sealing device for municipal drainage pipes. Background Technology

[0002] Municipal drainage pipes are an important part of urban infrastructure, responsible for collecting and transporting rainwater and domestic sewage to ensure the normal operation of the city and flood control and drainage.

[0003] During emergency repairs of drainage pipes, a rapid leak-sealing device is needed to seal the leaking section. For example, Chinese Patent Publication No. CN223076563U discloses a rapid leak-sealing device for drainage pipes, comprising a covering tape and a connecting assembly. Both ends of the covering tape are fixedly fitted with snap-fit ​​strips, and connecting blocks are slidably fitted onto the surfaces of the snap-fit ​​strips on both sides. Insert seats are fixedly installed on the surfaces of the connecting blocks, and insertion holes are provided on the surfaces of the insert seats. The connecting assembly includes a connecting screw and a transition plate, with both sides of the transition plate inclined upwards. The insert seats and connecting assembly are assembled together, and the covering tape is tightened to wrap around the surface of the pipe to be repaired. This rapid leak-sealing device for drainage pipes, through the assembly of the covering tape and connecting assembly, tightens and wraps the covering tape around the surface of the pipe to be repaired. Because the covering tape can be freely bent, it can match the curvature of the pipe surface well, and the covering area is large, resulting in a good sealing effect. This design makes it suitable for sealing leaks in pipes of various diameters, demonstrating strong applicability.

[0004] In practice, the covering tape needs to be fixed to the surface of the drain pipe in conjunction with the transition plate and multiple locking bolts on both sides of the transition plate. However, considering that the connection by locking bolts is inefficient and cannot quickly fix the leak-sealing device to the surface of the drain pipe, its practicality is poor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot quickly fix the sealing device to the surface of the drainage pipe, and to propose a rapid sealing device for municipal drainage pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a rapid leak-sealing device for municipal drainage pipes, including a support base. The support base is fixed to the outer wall of the drainage pipe by an arc-shaped groove on the end face and connecting structures on both sides. The connecting structures are provided in at least two, and the connecting structures are detachably connected to the support base by a quick-release structure.

[0008] A leak-sealing structure is provided on the surface of the arc-shaped groove and on the back of the support base.

[0009] Furthermore, the connection structure consists of a pair of connectors, which together form a U-shaped structure, with their recessed portions engaging with the outer wall of the drain pipe, and the bent portions of the pair of connectors being rotatably connected.

[0010] Furthermore, the free end of one of the connectors is fixedly connected to the support base by a fastener, and the support base has a receiving groove on one side that communicates with the side, and the functional end of the other connector is movably connected in the receiving groove.

[0011] Furthermore, the quick-release structure includes a support portion, which is sleeved on the functional end of the movable connector, and an eccentric rod is pinned to it. The eccentric rod rotates eccentrically to drive the support portion to press against the support seat.

[0012] Furthermore, the leak-sealing structure includes a pressure relief valve, which is fixedly connected to the back of the support base and is connected to the arc-shaped groove through a delivery pipe.

[0013] Furthermore, the leak-stopping structure also includes a water-stopping layer, which is bonded to the arc-shaped groove with Velcro. The water-stopping layer is also provided with a drain outlet that is connected to the pressure relief valve.

[0014] The present invention provides a quick leak-sealing device for municipal drainage pipes, which has the following advantages: The support base of the present invention is fixed to the outer wall of the drainage pipe where the leak needs to be sealed by a pair of connecting parts on both sides. The movable connecting parts can be quickly locked or unlocked by the quick-release structure. By locking the pair of connecting parts on both sides, the support base can be fixed to the surface of the pipe to be repaired. Then, by reversing the eccentric rod, the movable connecting parts can be quickly unlocked, which effectively improves the disassembly and assembly efficiency of the support base. In addition, the support base is also provided with a pressure relief structure. When the support base is fixed by the pressure relief valve, the high-pressure water flow sprayed from the leak can be relieved, so as to avoid the water pressure being too strong and affecting the fixation of the support base.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A quick-plugging device for municipal drainage pipes includes a support base 1. The support base 1 is fixed to the outer wall of the drainage pipe through an arc groove 2 on the end face and connecting structures 3 on both sides. There are at least two connecting structures 3. The connecting structures 3 and the support base 1 are detachably connected through a quick-release structure 4.

[0021] Among them, a leak-stopping structure 5 is provided on the surface of the arc-shaped groove 2 and on the back of the support 1.

[0022] Furthermore, the connection structure 3 consists of a pair of connectors 31. The pair of connectors 31 are closed to form a U-shaped structure, and their recessed parts are engaged with the outer wall of the drain pipe. The bent parts of the pair of connectors 31 are rotatably connected.

[0023] Furthermore, the free end of one of the connectors 31 is fixedly connected to the support base 1 by a fastener 6. The support base 1 has a receiving groove 11 on one side that communicates with the side, and the functional end of the other connector 31 is movably connected to the receiving groove 11.

[0024] In this embodiment, as Figure 2 As shown, the fastener 6 consists of a nut and a baffle. The baffle is fixedly connected to the end of the fixed connector 31, and the nut is threadedly connected to it. The baffle and the nut abut against the upper and lower sides of the support base 1, respectively, thereby fixing one of the connectors 31.

[0025] More specifically, the quick-release structure 4 includes a support part 41, which is sleeved on the functional end of the movable connector 31, and an eccentric rod 42 is pinned to it. The eccentric rod 42 rotates eccentrically to drive the support part 41 to press against the support seat 1.

[0026] It should be added that the structure of the eccentric rod 42 and the support part 41 fastening the connecting piece 31 by eccentric rotation can be referred to in the prior art bicycle seat adjustment clamp structure.

[0027] In specific operation, when the eccentric rod 42 flips, it presses against the support part 41 by eccentric contact. The support part 41 is pressed against the support seat 1 to lock the movable connecting piece 31. In this way, the pair of connecting pieces 31 can fix the support seat 1 on the surface of the drain pipe to be repaired when locked and fixed.

[0028] Specifically, after the eccentric rod 42 is reversed to unlock the support part 41, the support part 41 is intermittently separated from the bottom of the support base 1. At this time, the movable connector 31 can be flipped over, and then the entire leak-sealing device can be removed.

[0029] Among them, a pair of connectors 31 are rotated by a pin, and the pin can be inserted on the bent end near the fixed connector 31 to prevent the movable connector 31 from getting stuck with the drain pipe when it flips over.

[0030] In general, the leak-sealing structure 5 includes a pressure relief valve 51, which is fixedly connected to the back of the support base 1 and is connected to the arc-shaped groove 2 through a delivery pipe.

[0031] Finally, the leak-stopping structure 5 also includes a water-stopping layer 52, which is bonded to the arc-shaped groove 2 by Velcro 53. The water-stopping layer 52 is also provided with a drain outlet 54 that is connected to the pressure relief valve 51.

[0032] It is worth mentioning that if the high-pressure water jet from the damaged drainage pipe is directly fitted and fixed to the support base 1, the high-pressure water jet will affect the operation. The pressure relief valve 51 is used to relieve the pressure of the jetting water jet, making it easier to fit and fix the support base 1.

[0033] Specifically, after the support base 1 is fixed, the quick-release structure 4 drives the support base 1 to be fastened to the outer wall of the drain pipe. At the same time, the water-stop layer 52 is pressed and adhered to the surface of the drain pipe to seal the outer wall of the drain pipe and prevent water from continuing to leak.

[0034] More specifically, after the support base 1 is fixed, the pressure relief valve 51 can be closed to temporarily plug the leak in the pipeline to be repaired, while waiting for the subsequent maintenance process.

[0035] It should be added that the waterstop layer 52 generally includes a base treatment layer, a waterproof layer and a rubber layer. The rubber layer can be used to drive the waterstop layer 52 to be compressed and then tightly adhered to the outer wall of the drainage pipe.

[0036] Among them, the Velcro 53 is existing technology and is used to replace the damaged waterproof layer 52 after long-term use.

[0037] Working method: During operation, the support seat 1 is fitted onto the location where the leak needs to be plugged in the pipe through the connecting structures 3 on both sides, and the support seat 1 is also attached to the outer wall of the drain pipe through the arc groove 2 on the end face.

[0038] Then, flip the connector 31 and place it in the receiving groove 11. Then rotate the eccentric rod 42. The eccentric rod 42 drives the support part 41 to press against the bottom of the support base 1 through eccentric contact. During the pressing process, the movable connector 31 is locked. A pair of connectors 31 can fix the support base 1.

[0039] While the support base 1 is being fitted, the pressure relief valve 51 will also release the pressure of the sprayed high-pressure water flow. After the support base 1 is fixed, the pressure relief valve 51 can be closed. In addition, after long-term use, the water-stop layer 52 can be replaced directly through the Velcro 53.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
