[0028] The working principle of the above-mentioned salvage device is as follows:

[0029] During use, the user places the salvage device in the oil well through the main lifting rope, and then adjusts the left and right angles of the device through the left and right adjustment ropes on the left and right adjustment rings 3. The device is flexible for transportation, so there is no need to design a rotating device. The magnetic block 16 in the bottom adsorption mechanism 1 can absorb and salvage metal objects in the oil well. The rope limiting mechanism 4 set therein can pass the main lifting rope of the device into the rope threading tube 44 before the salvage device is used, and then pass the left and right adjustment ropes into the limiting pulley 43. The limiting pulley 43 can prevent the main lifting rope and the left and right adjustment ropes from being entangled with each other and affecting the use of the device, and can also facilitate people to operate. The left and right adjustment ropes are used to fine-tune the device left and right. Since the device is symmetrical front and back, no front and back adjustment is required. The bottom adsorption mechanism 1 set therein can be used to install the mounting base 14 to the lower end of the device housing 2 by installing screws 15 when the salvage device is in use. The bottom fixing frame 11 and the connecting frame 13 form a conical structure, which increases the salvage area of ​​the bottom end face. At the same time, the larger outer diameter of the bottom end face is restricted by the well wall and is more stable. The device can collect small ferromagnetic fallen objects into the conical structure to the greatest extent at the bottom of the well, thereby improving the stability of the device. The magnetic suction block 16 can adsorb the salvaged metal objects and improve the overall salvage efficiency of the device.
