Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] As attached Figures 1 to 5 The shown device is an airbag pipeline sealing device for not going down into the well, comprising a supporting bracket 1 and an airbag tightening bracket 9, wherein stabilizing brackets 5 are arranged on the four sides of the supporting bracket 1, and a fixing ring 2 is arranged at the center of the four groups of stabilizing brackets 5, and telescopic rods 3 are installed on both sides of the inner wall of the fixing ring 2, and an airbag inflation tube 4 is placed under the inner wall of the telescopic rod 3, and the airbag tightening bracket 9 is arranged on the side of the telescopic rod 3 away from the supporting bracket 1 and away from the fixing ring 2.

[0024] Among them: when the airbag is used, the stabilizing bracket 5 is installed above the supporting bracket 1. After the installation is completed, the supporting bracket 1 is erected above the pipe to be blocked by the stabilizing bracket 5, and then the fixing ring 2 is installed on the top of the telescopic rod 3, and then the telescopic rod 3 is fixed at the center of the fixing ring 2 by the fixing ring 2, so that the airbag tightening bracket 9 under the telescopic rod 3 is above the inner wall of the blocked channel, thereby completing the pre-placement of the airbag tightening bracket 9. Example

[0025] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 5 As shown, see the following description for details:

[0026] As a preferred embodiment, the airbag tightening bracket 9 includes an expansion plate 901, a tightening belt 10, an extrusion protrusion 11 and an inflatable airbag bag 12, and the tightening belt 10 is wrapped around the top of the expansion plate 901, and the inflatable airbag bag 12 is arranged on the side of the expansion plate 901 away from the tightening belt 10, and the extrusion protrusion 11 is arranged on the inner wall of the expansion plate 901. When the airbag tightening bracket 9 is placed at the opening of the pipe to be blocked through the telescopic rod 3, the gas is filled into the inflatable airbag bag 12 through the inflation head 14 connected to the airbag inflation tube 4. At this time, the inflatable airbag bag 12 folded into the airbag tightening bracket 9 enters the air, and then the inflatable airbag bag 12 squeezes the expansion plate 901 during the continuous expansion process, and then the expansion plate 9 01 continuously squeezes the tightening band 10 on the outer surface, and when the specified expansion amplitude is reached, the inflatable airbag bag 12 squeezes the extrusion protrusion 11 inside the expansion plate 901, so that the extrusion protrusion 11 is squeezed out, and then the extrusion protrusion 11 protrudes out of the expansion plate 901, so that the tip of the top of the extrusion protrusion 11 squeezes the tightening band 10, so that the force position of the tightening band 10 changes, so that the tightening band 10 is cut, and then the inflatable airbag bag 12 releases the extrusion force applied by the expansion plate 901, so that the inflatable airbag expands inside the blocked pipe. Since the expansion plate 901 of the airbag tightening bracket 9 is specifically made of rubber material, when the inflatable airbag bag 12 squeezes the expansion plate 901, the outer surface of the inflatable airbag bag 12 will not be squeezed by the expansion plate 901 and malfunction.

[0027] As a preferred embodiment, a pressure control valve 16 is provided on the side of the airbag inflation tube 4 away from the telescopic rod 3, and a pressure gauge 17 is provided on the side of the airbag inflation tube 4 away from the telescopic rod 3, and the gas output therein is controlled by the pressure control valve 16 installed on the airbag inflation tube 4, so that the output of the gas is controlled by the pressure control valve 16, and at the same time, the pressure delivered into the inflatable airbag bag 12 is fed back through the pressure gauge 17, so as to confirm the gas pressure inside the inflatable airbag bag 12.

[0028] As a preferred embodiment, an adjusting ring 15 is installed on the outer surface of the telescopic rod 3, and a connecting bracket 13 is provided at the center of the telescopic rod 3 and the airbag tightening bracket 9, and an inflation head 14 is installed on the side of the connecting bracket 13 away from the telescopic rod 3, and its extension length on the telescopic rod 3 is adjusted by the adjusting ring 15. By rotating the adjusting ring 15, the restriction of the extension rod portion of the telescopic rod 3 is released, so that the airbag tightening bracket 9 is brought into the pipe that needs to be blocked by the telescopic rod 3.

[0029] As a preferred embodiment, the stabilizing bracket 5 includes a first mounting bracket 6, a connecting hole 501, a rotating shaft 7 and a second mounting bracket 8, and a rotating shaft 7 is provided on the side of the first mounting bracket 6 away from the mounting bracket, and a second mounting bracket 8 is provided on the side of the rotating shaft 7 away from the first mounting bracket 6, and a detachable structure is formed between the stabilizing bracket 5 and the supporting bracket 1 through the connecting hole 501 and bolts, and the stabilizing bracket 5 is connected to the supporting bracket 1 through the connecting hole 501 on the first mounting bracket 6 and fixed by bolts, thereby completing the fixation of the stabilizing bracket 5, and at the same time, the first mounting bracket 6 and the second mounting bracket 8 adjust the angle between the first mounting bracket 6 and the second mounting bracket 8 through the adjusting shaft, so that the telescopic rod 3 can adapt to different heights.

[0030] As a preferred embodiment, a stainless steel connecting ring 18 is provided on the side of the inflation head 14 away from the inflatable airbag bag 12, and the stainless steel connecting ring 18 and the expansion plate 901 are buckled to form a rotating structure, and the expansion plate 901 is connected to the stainless steel connecting ring 18. When the expansion plate 901 is restricted, the expansion plate 901 connected by the tightening belt 10 and the stainless steel connecting ring 18 can collect the folded inflatable airbag bag 12.

[0031] The working process of the utility model is as follows: when the airbag tightening bracket 9 is placed at the opening of the pipe to be blocked through the telescopic rod 3, the gas is filled into the interior of the inflatable airbag bag 12 through the inflation head 14 connected to the airbag inflation tube 4. At this time, the inflatable airbag bag 12 folded into the airbag tightening bracket 9 enters the air, and then the inflatable airbag bag 12 is in the process of continuous expansion. The inflatable airbag bag 12 squeezes the expansion plate 901, and then the expansion plate 901 continuously squeezes the tightening belt 10 on the outer surface. When the specified expansion amplitude is reached, the inflatable airbag bag 12 squeezes the extrusion convex inside the expansion plate 901. The block 11 is pressed out, and then the pressed protrusion 11 protrudes out of the expansion plate 901, so that the tip of the top of the pressed protrusion 11 squeezes the tightening belt 10, so that the force position of the tightening belt 10 changes, so that the tightening belt 10 is cut, and then the inflatable airbag bag 12 releases the extrusion force applied by the expansion plate 901, so that the inflatable airbag expands inside the blocked pipe. Since the expansion plate 901 of the airbag tightening bracket 9 is specifically made of rubber material, when the inflatable airbag bag 12 squeezes the expansion plate 901, the outer surface of the inflatable airbag bag 12 will not be squeezed by the expansion plate 901 and fail, and the input The gas discharged is controlled by the air pressure control valve 16 installed on the airbag inflation tube 4, so as to control the output of the gas through the air pressure control valve 16, and at the same time, the pressure delivered into the inflatable airbag bag 12 is fed back through the pressure gauge 17, so as to confirm the gas pressure inside the inflatable airbag bag 12, and the extension length of the telescopic rod 3 is adjusted by the adjustment ring 15, and the restriction of the extension rod part of the telescopic rod 3 is loosened by rotating the adjustment ring 15, so that the airbag tightening bracket 9 is brought into the pipeline to be blocked by the telescopic rod 3, and the stabilizing bracket 5 is connected to the support through the connecting hole 501 on the first mounting bracket 6 The bracket 1 is connected and fixed by bolts to complete the fixation of the stable bracket 5, and at the same time, the first mounting bracket 6 and the second mounting bracket 8 adjust the angle between the first mounting bracket 6 and the second mounting bracket 8 through the rotating shaft 7, so that the telescopic rod 3 can adapt to different heights, and the expansion plate 901 is connected to the stainless steel connecting ring 18. When the expansion plate 901 is restricted, the expansion plate 901 connected by the tightening belt 10 and the stainless steel connecting ring 18 can collect the folded inflatable airbag bag 12. The above is the working principle of the non-downhole airbag pipeline sealing device.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
