Description

Technical Field

[0001] This utility model relates to the technical field of pipeline sealing devices, specifically an adjustable drainage pipeline sealing device. Background Technology

[0002] During the construction, maintenance, or inspection of drainage pipes, it is often necessary to temporarily seal the pipes to prevent water or debris from entering the work area. Traditional sealing methods typically use sandbags, rubber plugs, or fixed-size sealing devices, which have poor adaptability, are difficult to adapt to the sealing requirements of different pipe diameters, and are relatively inconvenient to operate, requiring the use of external tools (such as air pumps) or multiple people to complete the sealing.

[0003] Therefore, this application provides an adjustable drainage pipeline sealing device to solve the problems of existing sealing devices being inconvenient to adapt to different pipe diameter sealing requirements and being difficult to operate. Utility Model Content

[0004] To solve the above problems, this utility model provides an adjustable drainage pipeline sealing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable drainage pipeline sealing device, including a sealing airbag and an operating rod. The sealing airbag has a connecting hole on its axis, a connecting sleeve is provided at one end of the sealing airbag, an operating handle is provided at one end of the operating rod, and the other end of the operating rod passes through the connecting sleeve and the connecting hole and is located at the bottom of the sealing airbag.

[0006] The operating lever is equipped with a limiting wedge, and the inner side of the connecting sleeve is provided with a limiting ratchet along the length direction. The limiting wedge is positioned opposite to the inner side of the limiting ratchet. After the connecting sleeve is pushed to squeeze the sealing airbag, the limiting ratchet engages with the limiting wedge to lock the state of the sealing airbag.

[0007] As an optimization, the diameter of the sealing airbag gradually decreases from the middle to both ends, and the two ends of the sealing airbag converge to form a plane.

[0008] As an optimization, a first compression plate is provided at the end of the operating lever away from the operating handle, and a second compression plate is provided at the end of the connecting sleeve adjacent to the sealing airbag. The first compression plate and the second compression plate are arranged in parallel and opposite to each other on both sides of the sealing airbag.

[0009] As an optimization, both the first extrusion plate and the second extrusion plate include a fixed end piece and an extension ring. The extension ring is detachably connected to the fixed end piece. Both the extension ring and the fixed end piece have limit holes, and the interior of the limit holes accommodates limit pins.

[0010] As an optimization, a receiving groove is provided in the upper middle part of the operating lever, the limiting wedge is slidably disposed inside the receiving groove, a support spring is provided inside the receiving groove, and the limiting wedge is fixedly connected to the support spring.

[0011] As an optimization, the connecting sleeve can be moved along the operating rod to the end away from the operating handle;

[0012] One side of the limiting wedge is retracted to form a guide slope. Rotating the operating lever can push the limiting wedge to retract inwards.

[0013] As an optimization, the upper end of the operating lever is provided with a threaded portion, and the operating handle is provided with a connecting screw hole for accommodating the threaded portion.

[0014] The beneficial effects of this plan are as follows:

[0015] This application achieves convenient adjustment of the diameter of the sealing airbag through the elastic deformation of the sealing airbag and the lockable adjustment of the limiting ratchet-limiting wedge structure, which can adapt to the sealing requirements of different pipe diameters.

[0016] Pushing the connecting sleeve allows the airbag to be fixed in place by engaging the limiting ratchet and wedge, requiring no additional tools and making the operation convenient;

[0017] The first and second extrusion plates are arranged in parallel and opposite directions to evenly distribute the pressure, ensure uniform deformation of the sealing airbag, and improve sealing stability. Attached Figure Description

[0026] like Figures 1-7 As shown, an adjustable drainage pipeline sealing device includes a sealing airbag 1 and an operating rod 2. The sealing airbag 1 has a connecting hole 5 at its axis. One end of the sealing airbag 1 is equipped with a connecting sleeve 3. One end of the operating rod 2 is equipped with an operating handle 4. The other end of the operating rod 2 passes through the connecting sleeve 3 and the connecting hole 5 and is located at the bottom of the sealing airbag 1.

[0027] The operating lever 2 is equipped with a limiting wedge 6, and the inner side of the connecting sleeve 3 is provided with a limiting ratchet 7 along the length direction. The limiting wedge 6 is disposed opposite to the inner side of the limiting ratchet 7. After the connecting sleeve 3 is pushed to squeeze the sealing airbag 1, the limiting ratchet 7 and the limiting wedge 6 are engaged to lock the state of the sealing airbag 1.

[0028] The sealing airbag 1 is made of high-strength rubber material (such as EPDM or neoprene rubber), which has excellent elasticity and corrosion resistance. The sealing airbag 1 is equipped with stretchable pleats, which can be flattened in the middle, making it suitable for sewage environments in drainage pipes.

[0029] The operating lever 2 is made of stainless steel with rust-proof treatment. The operating lever 2 is sealed to the connection hole 5.

[0030] like Figure 2 As shown, the diameter of the sealing airbag 1 gradually decreases from the middle to both ends, and the two ends of the sealing airbag 1 converge to form a plane.

[0031] Pushing the connecting sleeve 3 can simultaneously compress the upper and lower ends of the sealing airbag 1, causing the middle part of the sealing airbag 1 to extend outward. Depending on the inner diameter of the sealing pipe, the sealing airbag 1 can be compressed to different degrees.

[0032] like Figure 2 As shown, the end of the operating lever 2 away from the operating handle 4 is provided with a first extrusion plate, and the end of the connecting sleeve 3 adjacent to the sealing airbag 1 is provided with a second extrusion plate. The first extrusion plate and the second extrusion plate are arranged in parallel opposite directions on both sides of the sealing airbag 1.

[0033] The first extrusion plate and the sealing airbag 1 are in contact and sealed. The diameters of the first and second extrusion plates are not less than half the diameter of the sealing airbag 1. Furthermore, the diameters of the first and second extrusion plates can be adjusted according to the actual diameter of the pipe to be sealed. When the diameter of the pipe to be sealed is large, the diameters of the first and second extrusion plates also need to be increased accordingly.

[0034] like Figure 3 As shown, both the first extrusion plate and the second extrusion plate include a fixed end piece 8 and an extension ring 9. The extension ring 9 is detachably connected to the fixed end piece 8. Both the extension ring 9 and the fixed end piece 8 have limit holes, and the limit holes accommodate limit pins 10.

[0035] The extension ring 9 is coaxially arranged with the fixed end piece 8, and different sizes of extension ring 9 can be selected according to the diameter of the pipe to be sealed. The diameter of the first extrusion plate and the second extrusion plate is not greater than the inner diameter of the pipe to be sealed.

[0036] like Figure 3 As shown, the upper middle part of the operating lever 2 is provided with a receiving groove, the limiting wedge 6 is slidably disposed inside the receiving groove, the receiving groove is provided with a support spring 11, and the limiting wedge 6 is fixedly connected to the support spring 11.

[0037] Under the action of the support spring 11, the limiting wedge 6 can retract into the receiving groove.

[0038] like Figure 3 and Figure 7 As shown, the connecting sleeve 3 can move along the operating rod 2 to the end away from the operating handle 4;

[0039] One side of the limiting wedge 6 is retracted to form a guide slope 12. Rotating the operating lever 2 can push the limiting wedge 6 to retract into the operating lever 2.

[0040] The bottom surface of the limiting wedge 6 is a long plane, which is used to lock the limiting ratchet 7.

[0041] The limiting ratchet 7 is closed in the width direction. When the operating lever 2 is rotated, the guide slope 12 is pressed against the closed end, pushing the limiting ratchet 7 to retract into the receiving groove.

[0042] like Figure 3 As shown, the upper end of the operating lever 2 is provided with a threaded part, and the operating handle 4 is provided with a connecting screw hole, which is used to accommodate the threaded part.

[0043] The operating lever 2 and the operating handle 4 are detachably connected and can be assembled immediately during use.

[0044] When using this device, first select a suitable extension ring 9 according to the inner diameter of the pipe, and fix the extension ring 9 to the fixed end piece 8 with the limiting pin 10.

[0045] Connect and fix the operating handle 4 to the operating lever 2;

[0046] Insert the entire device into the pipe to be sealed, so that the first extrusion plate, the second extrusion plate and the sealing airbag 1 are all located inside the pipe to be sealed.

[0047] Push the connecting sleeve 3 to move it along the operating rod 2, flattening the sealing airbag 1 until the outer periphery of the sealing airbag 1 is pressed tightly against the inner wall of the pipe to be sealed.

[0048] The limiting ratchet 7 engages with the limiting wedge 6 to lock the sealing airbag 1.

[0049] After completing the operation, rotate the operating lever 2 to disengage the limiting wedge 6 from the limiting ratchet 7, release the lock on the connecting sleeve 3, and move the connecting sleeve 3 outward along the operating lever 2 to release the sealing airbag 1.

[0050] Simply pull the entire device outwards.

[0051] When the diameter of the pipe to be sealed is small, the extension ring 9 can be removed and used. Different sizes of extension ring 9 can be selected depending on the diameter of the pipe to be sealed. The extension ring 9 adopts a modular design and is easy to disassemble.
