[0002] The oil pipeline is used for transporting crude oil, and is generally a normal pressure oil pipeline. In use, the oil pipeline may leak. In order to find the leakage position in time, professional personnel need to conduct inspection. Once the leakage position is found, the leakage position is repaired. However, the applicant finds that it is difficult to find the position with small leakage when the oil pipeline is inspected, so that the leakage position cannot be repaired in time.

"Up", "down", "left", "right" and the like are only used to represent the relative positional relationship, and when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0080] The first aspect of the present application provides an oil pipe leak-proof detection and repair device, as shown in Figure 1 、 Figure 2 、 Figure 10 It comprises:

[0081] The track 17 arranged on both sides of the oil pipe, which is above the oil pipe;

[0082] The moving block 1 and the wheel set arranged on the lower surface of the moving block 1, the wheel set comprising two front wheels 9 and two rear wheels 13, when the two front wheels 9 roll on the track 17, the two rear wheels 13 are driven to roll on the track 17;

[0083] The oil pipe leak-proof detection and repair device further comprises:

[0084] The first driving part for driving the front wheels 9 to rotate, which is arranged in the moving block 1;

[0085] The fixed plate 3, the first circular ring 5 and the CCD camera 6 arranged on the inner side wall of the first circular ring 5, the lower surface of the moving block 1 is provided with a bottom groove 2, the top end of the fixed plate 3 is fixed to the top wall of the bottom groove 2, and the fixed plate 3 is provided with a first perforation 4 penetrating through both sides thereof, the first circular ring 5 is installed in the first perforation 4, and the central axis of the first circular ring 5 coincides with the central axis of the first perforation 4;

[0086] The rotating part for driving the first circular ring 5 to rotate in the first perforation 4;

[0087] The cylinder 60 arranged on one side of the fixed plate 3, the central axis of the cylinder 60 coincides with the central axis of the first circular ring 5, and the oil pipe passes through the first circular ring 5 and the cylinder 60;

[0088] A plurality of sealing rings 61 sleeved on the cylinder 60, the sealing rings 61 have elasticity;

[0089] The second drive unit is used to drive the sealing ring 61 to move along the axial direction of the cylinder 60.

[0090] In this embodiment, the specific steps are as follows: Step 1: The CCD camera 6 is started, and at the same time, it rotates, causing the first ring 5 to rotate; Step 2: After the CCD camera 6 rotates one revolution, the first drive unit is started, driving the moving block 1 forward a certain distance, and then the first drive unit stops driving. At this time, the distance moved by the moving block 1 is exactly the limit width observed by the CCD camera 6; Step 3: If no oil leak is found during the entire detection process, the detection ends. If an oil leak is found, the subsequent steps continue; Step 4: When the CCD camera 6 detects an oil leak in the oil pipe, the first drive unit drives the moving block 1 forward. When the oil leak is located exactly behind the cylinder 60, the first drive unit stops driving, and then the second drive unit drives the sealing ring 61 closest to the oil leak to move towards the oil leak. After the sealing ring 61 is separated from the cylinder 60, the oil leak is sealed by the contraction force of the sealing ring 61 itself; Step 5: The first drive unit drives the moving block 1 backward, so that the CCD camera 6 moves back to the oil leak location, and then steps 1 to 3 are repeated. Here, the CCD camera 6 can observe various parts of the oil pipe. The CCD camera 6 can transmit image information to the control room and determine whether there is an oil leak. If there is an oil leak, it can be repaired by the sealing ring 61. This invention can clearly observe various leak points through the CCD camera 6, including small leak points. After a leak point is found, it can be repaired in time by the sealing ring 61, thereby effectively reducing the amount of crude oil lost due to leakage. Of course, since the leak prevention effect of the sealing ring 61 is limited, if a large leak point is observed, after the initial sealing by the sealing ring 61, after all the inspections are completed, staff can be arranged to recheck the positions of the sealing ring 61 on the oil pipe, or measures can be taken to further seal the sealing ring 61 to ensure that the leak point is repaired in time.
