[0002] A water supply pipeline is a pipe used to convey water. Over time, problems and damages are inevitable, which will affect the water supply in this area. Therefore, professional maintenance personnel are needed to quickly repair the damaged pipeline in order to restore the water supply in time. During this repair process, for safety and convenient operation considerations, it is necessary to block the water supply pipeline and then repair it.

[0003] When repairing and blocking existing water supply pipelines, most of them directly force an object made of rubber material into the water supply pipeline to block the water supply pipeline. The blocking effect is not good, and it is not convenient to disassemble the rubber material object after the repair and blocking of the water supply pipeline. Content of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A water blocking device for repairing water supply pipelines includes a fixed disk. A center disk is fixedly installed between two fixed disks. An airbag is sleeved on the center disk. One of the fixed disks is fixedly installed with a connecting rod. An air port is arranged in the connecting rod. One end of the air port is provided with an installation groove in which a plug is installed. Both the installation groove and the plug are in a T shape. A spring is sleeved on the plug. One side of the plug is fixedly installed with a push rod. One end of the connecting rod is installed with a fixing component.

[0007] A further preferred scheme of the utility model: The fixing component includes a sleeve plate, a clamping plate and a fixing bolt. The sleeve plate is fixedly connected with the connecting plate. Fixing bolts are screwed on both sides of the sleeve plate. One end of the fixing bolt is rotatably connected with the clamping plate. The clamping plate is installed in the sleeve plate and the clamping plate is arc-shaped.

[0008] A further preferred scheme of the utility model: The top of the connecting rod is fixedly connected with the sleeve plate, and the top of the air port passes through the sleeve plate.

[0009] A further preferred scheme of the utility model: There is a passage between the air port, the connecting rod, the center disk and the airbag.

[0010] The utility model has the following beneficial effects:

[0011] By inflating the airbag and blocking the pipeline with the airbag, the utility model solves the problem that it is difficult to take out the object made of rubber material forced into the water supply pipeline, and improves the safety and reliability. Description of the Drawings

[0013] Figure 2 This is the front view sectional structural schematic diagram of the present utility model;

[0014] Figure 3 This is the enlarged structural schematic diagram of part A of the present utility model;

[0015] In the figure: 1 is a fixed disk, 2 is an airbag, 3 is a connecting rod, 4 is an air port, 5 is a sleeve plate, 6 is a fixing bolt, 7 is a central disk, 8 is a clamping plate, 9 is a plug, 10 is an installation groove, 11 is a spring, 12 is a push rod. Detailed Implementation Manner

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0017] According to Figures 1-3 As shown, a water blocking device for repairing a water supply pipeline includes a fixed disk 1. A central disk 7 is fixedly installed between two fixed disks 1. An airbag 2 is sleeved on the central disk 7. A connecting rod 3 is fixedly installed on one of the fixed disks 1. An air port 4 is arranged inside the connecting rod 3. One end of the air port 4 is provided with a plug 9 installed in an installation groove 10. Both the installation groove 10 and the plug 9 are in a T shape. A spring 11 is sleeved on the plug 9. A push rod 12 is fixedly installed on one side of the plug 9. A fixing component is installed at one end of the connecting rod 3.

[0018] The fixing component includes a sleeve plate 5, a clamping plate 8 and a fixing bolt 6. The sleeve plate 5 is fixedly connected to the connecting plate. Fixing bolts 6 are screwed on both sides of the sleeve plate 5. One end of the fixing bolt 6 is rotatably connected to the clamping plate 8. The clamping plate 8 is installed inside the sleeve plate 5, and the clamping plate 8 is arc-shaped.

[0019] The top of the connecting rod 3 is fixedly connected to the sleeve plate 5. The top of the air port 4 passes through the sleeve plate 5.

[0020] There is a passage between the air port 4, the connecting rod 3, the central disk 7 and the airbag 2.

[0021] Working principle: Place the end with the airbag 2 into the water supply pipeline. Control the clamping plate 8 to fix the water supply pipeline opening through the fixing bolt 6. Then, fill the air port 4 with gas. The gas compresses the plug 9, and the spring 11 contracts. The airbag 2 will be filled with gas to block the water supply pipeline. When the device needs to be removed, push in the push rod 12, the spring 11 compresses, the gas flows out through the air port 4, and unscrew the fixing bolt 6 to separate the device from the water supply pipeline.

[0022] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
