Similarly, the second extended umbrella surface bone 6 that is rotated and unfolded is arranged in coordination with the second reinforcing rib 9 to realize the rotation and unfolding of the third extended umbrella surface bone 7. Finally, the sealing rubber airbag 3 fixedly connected by the fixing ring 18 is unfolded through the unfolded first extended umbrella surface bone 4, the second extended umbrella surface bone 6, and the third extended umbrella surface bone 7.

[0033] As a preferred embodiment, two support seats 15 are fixedly sleeved on the outside of the main shaft rod 1, and then a base 14 is connected to the bottom walls of the two support seats 15, and a hydraulic push rod 13 is installed on the support seat 15, and then a moving sleeve 11 is connected to one end of the moving connecting seat 10, and then the moving sleeve 11 is slidably sleeved and connected to the outside of the main shaft rod 1, and the outer wall of the moving sleeve 11 is fixedly connected to the pushing seat 12, and finally the free end of the hydraulic push rod 13 is connected to the pushing seat 12; further, when the device is in use, the pushing seat 12 can be pushed by the hydraulic push rod 13 arranged on the support seat 15. The push causes the pushing seat 12 to move along the main shaft rod 1, and the pushed moving sleeve 11 further drives the moving connecting seat 10 and one end of the main support rod 5 rotatably connected to the moving connecting seat 10 to rotate, thereby quickly deploying the first extended umbrella rib 4, the main support rod 5, the second extended umbrella rib 6 and the blocking rubber airbag 3 connected thereto, thereby facilitating the rapid deployment of the blocking rubber airbag 3 when in use, and at the same time, the blocking rubber airbag 3 can also be quickly stored when not in use, thereby reducing the overall space occupied by the device, facilitating storage and placement, and improving the practicality of the device.

[0034] As a preferred embodiment, a one-way valve 23 is bolted to the support seat 15, and a discharge pipe 21 is connected to the output end of the one-way valve 23, and then the central axis of the main shaft 1 is passed through the discharge pipe 21, and a plurality of connecting pipes 22 are connected to one end of the discharge pipe 21, and one end of the discharge pipe 21 is connected to the plugging rubber airbag 3 through the plurality of connecting pipes 22, and the input end of the one-way valve 23 is connected to the input pipe 24, and one end of the input pipe 24 is connected to the output end of the air pressure high-pressure pump; further, when the device is in use, the one-way valve 23 can be opened, and the air pressure high-pressure pump power supply connected to one end of the input pipe 24 is opened, and then the air pressure high-pressure pump injects high-pressure gas into the discharge pipe 21 through the input pipe 24 and the one-way valve 23, and then the discharge pipe 21 injects high-pressure gas into the plugging rubber airbag 3 through the plurality of connecting pipes 22, so that the plugging rubber airbag 3 expands rapidly, and then the plugging rubber airbag 3 squeezes and seals the joint with the well wall.

[0035] As a preferred embodiment, a rotating sealing ring 16 is screwed and connected to the outer side of the end of the main shaft rod 1 close to the end plate 2, and an external thread screwed and connected to the rotating sealing ring 16 is arranged on the outer side of the end of the main shaft rod 1 close to the end plate 2, and a sealing rubber ring is installed on one side of the rotating sealing ring 16 close to the sealing rubber airbag 3; further, by setting the rotating sealing ring 16, the connection between the main shaft rod 1 and the sealing rubber airbag 3 can be further sealed, thereby improving the sealing effect of the entire device on the pipeline. When in use, the rotating sealing ring 16 can be screwed and rotated to a suitable position first, and then high-pressure gas is injected into the sealing rubber airbag 3, and then the rotating sealing ring 16 is squeezed by the inflated sealing rubber airbag 3 to seal the gap between the rotating sealing ring 16 and the sealing rubber airbag 3. Finally, you can try to rotate the rotating sealing ring 16 with the help of an external tool so that the rotating sealing ring 16 is close to the sealing rubber airbag 3, thereby improving the sealing between the rotating sealing ring 16 and the sealing rubber airbag 3.

[0036] The working process of the present invention is as follows: first, the base 14 is fixed, and then the first expansion umbrella surface bone 4, the second expansion umbrella surface bone 6, and the third expansion umbrella surface bone 7 are unfolded. When unfolding, the hydraulic push rod 13 arranged on the support seat 15 can push the pushing seat 12 so that the pushing seat 12 moves along the main shaft rod 1, and the pushed moving sleeve 11 further pushes the moving connecting seat 10 and one end of the main support rod 5 rotatably connected to the moving connecting seat 10 to rotate, and then the end of the main support rod 5 away from the moving connecting seat 10 pushes the first expansion umbrella surface bone 4 to rotate and unfold, and then the first expansion umbrella surface bone 4 and the second expansion umbrella surface bone 6 are rotated and connected by the cooperation of the first tensioning rib 8 connected, so that When one end of the first expansion umbrella rib 4 is rotated and unfolded, the second expansion umbrella rib 6 is pulled by the first tensioning rib 8 to rotate and unfold with the connection node 25 at one end of the main support rod 5 as the rotation point. Similarly, the second expansion umbrella rib 6 that is rotated and unfolded is arranged in cooperation with the second tensioning rib 9, thereby realizing the rotation and unfolding of the third expansion umbrella rib 7. Finally, the blocking rubber airbag 3 fixedly connected by the fixing ring 18 is unfolded by the unfolded first expansion umbrella rib 4, the second expansion umbrella rib 6, and the third expansion umbrella rib 7. At the same time, when not in use, the blocking rubber airbag 3 can also be quickly stored, thereby reducing the overall space occupied by the device, facilitating storage and folding, and improving the practicality of the device.

[0037] When it is necessary to introduce high-pressure gas into the sealing rubber airbag 3, the one-way valve 23 can be opened, and the power supply of the air pressure high-pressure pump connected to one end of the input pipe 24 can be opened. Then, the air pressure high-pressure pump injects high-pressure gas into the discharge pipe 21 through the input pipe 24 and the one-way valve 23, and then the discharge pipe 21 injects high-pressure gas into the sealing rubber airbag 3 through multiple connecting pipes 22, so that the sealing rubber airbag 3 expands rapidly, and then the sealing rubber airbag 3 squeezes and seals the joint with the well wall, thereby achieving a higher sealing effect. The above is the working principle of this kind of assembled quick-disassembly and quick-installation pipeline sealing robot.
