[0033] Exemplarily, the third fixing plate 291 also has the function of preventing pollutants from entering the interior of the mobile module 2, thereby ensuring the cleanliness of the interior of the mobile module 2 and protecting the components inside the mobile module 2 from damage.

[0035] Exemplarily, the guide wheel 292 is fixedly connected to the outer side of the main body 21 . When the mobile module 2 is moving, the guide wheel 292 rolls in the pipeline 1 , which can reduce the friction of the mobile module 2 when moving in the pipeline 1 .

[0036] Exemplarily, the guide wheels 292 are provided in multiple groups, and the multiple groups of guide wheels 292 are symmetrically arranged relative to the main body 21.

[0043] The present invention provides an intelligent pipeline plugging device, the working process of which is as follows:

[0044] (1) When preparing to enter the pipeline 1, first, for one of the mobile modules 2, start the second driving member 24, and drive the moving plate 27 to move away from the sealing rubber tube 262 through the second transmission member 290, so that a certain gap is left between the sealing rubber tube 262 and the inner wall of the pipeline 1; secondly, start the first driving member 23, and drive the rubber block 252 to rotate through the cam tensioning mechanism 251, so that a certain gap is left between the rubber block 252 and the inner wall of the pipeline 1. The same operation is performed for the other mobile module 2; finally, close all driving members, and the travel of all driving members is controlled by the controller, and the pipeline intelligent plugging device is placed in the pipeline 1.

[0045] (2) When preparing to enter the anchoring and sealing state, first, for one of the mobile modules 2, start the second driving member 24, and drive the moving plate 27 to move toward the direction of the sealing rubber tube 262 through the second transmission member 290, so that the sealing rubber tube 262 is pressed against the pipeline 1; secondly, start the first driving member 23, and drive the rubber block 252 to rotate through the cam tensioning mechanism 251, so that the rubber block 252 is pressed against the inner wall of the pipeline 1. The same operation is performed for the other mobile module 2. Finally, close all driving members, and the strokes of all driving members are controlled by the controller. The rubber block 252 can realize the anchoring of the intelligent plugger and the predetermined position of the inner wall of the pipeline 1, and the sealing rubber tube 262 can realize the sealing of the intelligent plugger and the predetermined position of the inner wall of the pipeline 1. At the same time, the position can be calibrated by the sensor 5.

[0046] (3) When the intelligent plugging device enters the moving state. After the plugging operation of pipeline 1 is completed, the pipeline intelligent plugging device is ready to move to the specified position of pipeline 1.

[0047] In the first step, for one of the mobile modules 2, the second driving member 24 is started, and the mobile plate 27 is driven to move away from the sealing rubber tube 262 through the second transmission member 290, so that a certain gap is left between the sealing rubber tube 262 and the inner wall of the pipe 1; the first driving member 23 is started, and the rubber block 252 is driven to rotate through the cam tensioning mechanism 251, so that a certain gap is left between the rubber block 252 and the inner wall of the pipe 1. At this time, this mobile module 2 is in a loose state, and the other mobile module 2 is in an anchored and sealed state.

[0048] In the second step, the third driving member 4 is started, so that the first transmission member 3 drives the mobile module 2 in the loose state to move through the guide wheel 292. After the mobile module 2 in the loose state moves a certain displacement, the third driving member 4 stops, and the mobile module 2 in the loose state stops moving. For the mobile module 2 in the loose state, the first driving member 23 is started, and the rubber block 252 is driven to rotate through the cam tensioning mechanism 251, so that the rubber block 252 is pressed against the inner wall of the pipe 1. At this time, the mobile module 2 is in an anchored state.

[0049] In the third step, for the other mobile module 2, the second driving member 24 is started, and the mobile plate 27 is driven to move away from the sealing rubber tube 262 through the second transmission member 290, so that a certain gap is left between the sealing rubber tube 262 and the inner wall of the pipe 1; the first driving member 23 is started, and the rubber block 252 is driven to rotate through the cam tensioning mechanism 251, so that a certain gap is left between the rubber block 252 and the inner wall of the pipe 1. At this time, this mobile module 2 is in a loose state, and the other mobile module 2 is in an anchored and sealed state.

[0050] In the fourth step, the third driving member 4 is started, so that the first transmission member 3 drives the mobile module 2 in the loose state to move through the guide wheel 292. After the mobile module 2 in the loose state moves a certain displacement, the third driving member 4 stops, and the mobile module 2 in the loose state stops moving. For the mobile module 2 in the loose state, the first driving member 23 is started, and the rubber block 252 is driven to rotate through the cam tensioning mechanism 251, so that the rubber block 252 is pressed against the inner wall of the pipe 1. At this time, the mobile module 2 is in an anchored state.

[0051] Repeat the above steps until the intelligent plugging device moves to the designated outlet position of the pipeline 1, and then close the third driving member 4 to stop moving.

[0052] (4) When the intelligent occluder is withdrawn from the pipeline 1, after the intelligent occluder moves to the designated exit position of the pipeline 1, first, for one of the mobile modules 2, the first driving member 23 is started, and the rubber block 252 is driven to rotate through the cam tensioning mechanism 251, so that a certain gap is left between the rubber block 252 and the inner wall of the pipeline 1; at the same time, the same operation is performed on the other mobile module 2; finally, when the two mobile modules 2 are in the loose state, the intelligent occluder is directly taken out from the exit of the pipeline 1, thereby realizing the state of the intelligent occluder withdrawing from the pipeline 1.
