[0032] Reference Figure 1 , Figure 2 and Figure 3The installation ring 2 is fixedly connected to the top end of the air bag 1 outside the air cock 4, the front inner wall of the installation ring 2 is fixedly connected with a sliding block 24 sliding into a sliding groove 23 to limit the installation of the installation ring 2, the front surface of the installation disc 3 is provided with the sliding groove 23 capable of cooperating with the sliding block 24 to install the installation ring 2, the sliding block 24 is movably inserted into the inner wall of the sliding groove 23, the sliding groove 23 penetrates the top end of the installation disc 3 and extends to the right rear quarter in a circular arc shape at the middle of the installation disc 3, after the sliding block 24 slides into the sliding groove 23 from the top end of the installation disc 3, the installation ring 2 is rotated to make the sliding block 24 clamped into the inner wall of the sliding groove 23 extending to the right rear quarter in a circular arc shape at the middle of the installation disc 3, so that the installation ring 2 can be installed and fixed, the extension rod 25 is slidingly connected to the left inner side of the horizontal rod 22 and penetrates the left side of the horizontal rod 22, the left side of the rubber plate 27 is provided as an arc surface, the arc surface can increase the fitting area with the pipeline and better support the air bag 1, the guide block 28 is horizontally and left-right slidingly connected to the inner wall of the long strip-shaped moving groove, the connecting rod 29 is hingedly connected to the left side of the guide ring 210 at the end away from the guide block 28, the fixing plate 26, the extension rod 25 and the connecting rod 29 are provided with two groups, and the two groups are symmetrically arranged with the center line of the horizontal rod 22 as the symmetric axis.
[0033] Working principle: in use, when the pipeline closed water test is performed, first, the installation preparation work of the device is performed, the sliding block 24 of the front inner wall of the installation ring 2 is aligned with the sliding groove 23 of the top end of the installation disc 3, the sliding block 24 is slid into the sliding groove 23, then the installation ring 2 is rotated to make the sliding block 24 clamped into the inner wall of the sliding groove 23 extending to the right rear quarter in a circular arc shape at the middle of the installation disc 3, the fixed connection of the installation ring 2 and the installation disc 3 is completed, at this time, the protective cap 31 is opened, the connecting pipe of the inflator is connected with the air cock 4, then the horizontal rod 22 is pushed to slowly put the air bag 1 into the downward pipeline to be tested in the pipeline opening, and drives the whole supporting assembly and the air bag 1 to move to a suitable position in the pipeline.
[0034] Further, by holding the crossbar 22 with one hand and rotating the threaded rod 211 with the other hand, the guide ring 210 is moved downward along the outer wall of the threaded rod 211 due to the threaded connection between the threaded rod 211 and the guide ring 210, forcing the right end of the connecting rod 29, which is hingedly connected to the left side of the guide ring 210, to move downward. The left end of the connecting rod 29 is hingedly connected to the guide block 28, which is horizontally slidingly connected to the long strip-shaped moving groove at the top end of the crossbar 22. Therefore, the guide block 28 is slidingly moved to the left along the long strip-shaped moving groove under the driving of the connecting rod 29, and the movement of the guide block 28 drives the extension rod 25, which is fixedly connected to the guide block 28, to move to the left, causing the fixed plate 26 to move to the left and the rubber plate 27 on the left to move to the left until the rubber plate 27 is tightly attached to the inner wall of the pipeline. Since the rubber plate 27 is made of rubber and has an arc-shaped surface on the left, the friction with the inner wall of the pipeline is increased, and the attachment area is also increased. The two sets of rubber plates 27 can more stably support the installation ring 2 and the air bag 1, so that the air bag 1 can be kept stable in the pipeline without manual support, and the injection of gas can be conveniently performed by one person, improving the convenience and pipeline repair efficiency.
[0035] Further, the air bag 1 can be inflated by using the inflator and the air nozzle 4. Since the protective cap 31 is connected to the top end of the installation disc 3 by the connecting rope 32, the protective cap 31 will not be lost. During the inflation process, the inflation of the air bag 1 is observed. When the air bag 1 is fully inflated and tightly attached to the inner wall of the pipeline, the pipeline is sealed. Then, water is injected into the pipeline for a closed water test. During the test, whether there is leakage around the pipeline is closely observed to determine the sealing performance of the pipeline.
[0036] After the test is completed, the gas in the air bag 1 is released to make the air bag 1 contract. The threaded rod 211 is rotated in the opposite direction to move the guide ring 210 upward. The guide block 28, the extension rod 25, the fixed plate 26, and the rubber plate 27 are moved inward by the connecting rod 29, so that the rubber plate 27 is separated from the inner wall of the pipeline. Then, the air bag 1 can be taken out of the pipeline, and the closed water test is completed.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
