Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0023] By providing a pipeline plugging device for pipeline emergency repair in the embodiments of the present application, the problems that the traditional airbag cannot achieve sealing stability when the water pressure is relatively high, and it is easy to shift or slide inside the pipeline, resulting in poor sealing stability, and the current operation of sealing the pipe orifice is cumbersome and inconvenient are solved.

[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0025] An embodiment of the present utility model discloses a pipeline plugging device for pipeline emergency repair. As shown in the attached Figures 1-4 figures, it includes a plugging device seat 2 that is positioned and clamped on the pipeline main body 1. A clamping and positioning block 3 is provided at the bottom of the plugging device seat 2, and the pipeline main body 1 is clamped between two groups of clamping and positioning blocks 3.

[0026] A driving mechanism for adjusting the clamping and positioning block 3 is provided on the plugging device seat 2.

[0027] A bearing plate 4 is fixedly connected to the plugging device seat 2. A plug 5 is fixedly connected to the bearing plate 4. An airbag main body 6 is fixedly connected to the outside of the plug 5, and the airbag main body 6 is clamped between the plug 5 and the pipeline main body 1.

[0028] The driving mechanism includes a double-threaded screw rod 201 that is rotatably connected inside the plugging device seat 2. An adjusting block 202 is slidably connected inside the plugging device seat 2. A slider 203 is fixedly connected between the adjusting block 202 and the clamping and positioning block 3. The adjusting block 202 is threadedly connected to the double-threaded screw rod 201. The structure of the driving mechanism is compact and easy to use. By rotating the double-threaded screw rod 201, the two groups of adjusting blocks 202 can be synchronously driven to move. The adjusting block 202 drives the slider 203 and the clamping and positioning block 3 to move, so that the two groups of clamping and positioning blocks 3 can quickly clamp and position the pipeline main body 1.

[0029] Furthermore, a guide rail rod 204 is fixedly connected to the plugging device seat 2, and the adjusting block 202 is slidably connected to the guide rail rod 204. The provided guide rail rod 204 provides support and limit for the adjusting block 202 to ensure the stable force of the adjusting block 202.

[0030] Further, a chute 2031 corresponding to the slider 203 is provided on the plugging device base 2. The provided chute 2031 provides lateral support for the slider 203 to ensure the stable force on the slider 203.

[0031] A rotating handle 2011 is provided on the double-threaded lead screw 201. The provided rotating handle 2011 makes it labor-saving and convenient to rotate the double-threaded lead screw 201.

[0032] Further, an air tube 601 is fixedly connected to the airbag main body 6. The air tube 601 passes through the bearing plate 4 and is fixedly connected to an air nozzle 602. The provided air tube 601 and air nozzle 602 facilitate the inflation of the airbag main body 6. The airbag main body 6 is attached to the plug 5, which can reduce the volume of the airbag main body 6 and enhance the stability of the airbag main body 6.

[0033] A rubber pad 301 is fixedly connected to the clamping and positioning block 3. The provided rubber pad 301 makes the clamping and positioning block 3 stable and not easy to loosen when clamping the pipeline main body 1.

[0034] The pipeline plugging device for pipeline emergency repair is convenient to quickly plug the pipeline main body 1 during use, and has a good plugging effect.

[0035] During operation, first insert the plug 5 into the inside of the pipeline main body 1, and then drive the clamping and positioning block 3 to adjust the position through the plugging device base 2 and the driving mechanism, so that the two groups of clamping and positioning blocks 3 clamp the outer wall of the pipeline main body 1 to provide position support and fixation for the bearing plate 4, the plug 5 and the airbag main body 6.

[0036] Finally, inflate the inside of the airbag main body 6 through the air nozzle 602 and the air tube 601, so that after the airbag main body 6 expands, it quickly plugs the inside of the pipeline main body 1.

[0037] This plugging method is simple to operate. The plugging device base 2 and the clamping and positioning block 3 are used to quickly clamp and position the plugging device with the outer wall of the pipeline main body 1, and then cooperate with the designs of the bearing plate 4, the plug 5 and the airbag main body 6 to realize the internal plugging of the pipeline main body 1. The airbag main body 6 can be supported by the bearing plate 4 and the plug 5, is not easy to loosen, and has a good sealing effect, so that the pipeline plugging is convenient and stable.

[0038] When using the driving mechanism to adjust the position of the clamping and positioning block 3, just directly rotate the double-threaded lead screw 201. The double-threaded lead screw 201 drives the adjusting block 202 to move, the adjusting block 202 drives the slider 203 to move, and the slider 203 drives the clamping and positioning block 3 to move. Therefore, the two groups of clamping and positioning blocks 3 can conveniently and quickly clamp and position the pipeline main body 1.
