This patent increases the stability of the anchor body during the lowering process into the oil well to prevent it from touching the inner cavity of the oil well and causing damage. There are a large number of smaller garbage in the oil well that are enough to pass through the gap between two adjacent salvage movable rods, which results in the salvage anchor being able to salvage only larger garbage.

[0031] The working principle of the above embodiment is:

[0032] (1) When the filter screen 104 and the connection frame 105 need to be opened to salvage garbage, the drive motor 101 is started. The drive motor 101 drives the rotating shaft 102 to rotate through the output shaft, and drives the rotating seat 103 to rotate together through the rotating shaft 102. The connecting frame 105 drives the filter screen 104 to rotate together with the rotating seat 103. At the same time, the connecting frame 105 drives the two connecting plates 111 to rotate together, so that the support plate 110 rotates outside the second rotating rod 112. At the same time, the support plate 110 rotates on the outside of the first rotating rod 106. The outer side rotates and drives the first rotating rod 106 to move downward. The positioning plate 107 moves with the first rotating rod 106 and drives the slider 108 to move downward until the filter screen 104 is flipped to a suitable inclination slope. The interception mechanism 1 adjusts the inclination angle of the filter screen 104 and the connecting frame 105 through the cooperation of the driving motor 101, the rotating shaft 102 and the rotating seat 103, so that four interception nets are opened around the anchor body 2 to salvage garbage. At the same time, the filter screen 104 can filter out the oil residue and salvage the garbage in the oil well.

[0033] (2) When the stabilizing clamping ring 5 needs to be replaced, the two rotating boxes 402 are rotated, and the rotating boxes 402 drive the two positioning rods 401 to rotate together, and drive the movable plate 406 to rotate together through the positioning rods 401. The screw 403 rotates together with the movable plate 406 and pushes the movable plate 406 toward the inside of the rotating box 402. When the movable plate 406 is in contact with the inner cavity wall of the rotating box 402 away from the connecting seat 405, the screw 403 is completely separated from the fixing block 404. At this time, the stabilizing clamping ring 5 can be moved to the right to take out the fixing block 404 for replacement. The connection mechanism 4 facilitates the staff to replace different types of stabilizing clamping rings 5 ​​through the cooperation of the positioning rods 401, the rotating box 402, the screw 403, the fixing block 404, the connecting seat 405, the movable plate 406 and the limit block 407, so that the salvage anchor can be fixed on the outside of oil pipes of different thicknesses, thereby expanding the use range of the salvage anchor.
