DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0026] like Figure 1-Figure 2 As shown, the utility model proposes a directional well fishing device, which includes a mounting shell 1, a pair of fixed shafts 13 are arranged in the mounting shell 1, and an anti-drop component 2 is movably arranged on the two fixed shafts 13. A transmission component 3 is also movably arranged in the mounting shell 1, and the anti-drop component 2 and the transmission component 3 are transmission-connected.

[0027] like Figure 3 As shown, two symmetrical limiting grooves 10 are provided on the front and back surfaces of the mounting shell 1, and a stop plate 11 is provided at the bottom of the limiting groove 10. A sliding hole 12 is provided on the stop plate 11, and movable grooves 14 corresponding to the connecting handle 24 are provided on the left and right side surfaces of the mounting shell 1; a storage tray 15 is provided on the top of the mounting shell 1, and a sliding hole 2 17 communicating with the interior of the mounting shell 1 is provided in the middle of the storage tray 15, and a plurality of first flow holes 16 are also provided around the sliding hole 2 17.

[0028] like Figure 4 As shown, the anti-drop assembly 2 includes a pair of transmission gears 25 respectively arranged on two fixed shafts 13, a connecting handle 24 is provided on one of the transmission teeth of the transmission gear 25, and the end of the connecting handle 24 away from the transmission gear 25 is provided in the square cover 20, and a conical cover 21 is provided at the bottom of the square cover 20; a second flow hole 22 and a third flow hole 23 are respectively provided on the inner bottom surfaces of the square cover 20 and the conical cover 21.

[0029] like Figure 5As shown, the transmission assembly 3 includes a transmission rod 30 slidably set in the sliding hole 17, and a transmission rack 32 is set at the bottom of the transmission rod 30. The transmission rack 32 is respectively meshed with the transmission gears 25 on both sides. Limit blocks 34 are symmetrically arranged above the front and back sides of the transmission rack 32. The limit blocks 34 are movably set in the limit groove 10. A sliding rod 35 is set at the bottom of the limit block 34. The sliding rod 35 is movably inserted in the sliding hole 12. A spring 36 is sleeved on the outer side of the sliding rod 35, and the spring 36 is set between the limit block 34 and the support plate 11; a connecting cap 31 is set at the top of the transmission rod 30, and an internal thread is set in the connecting cap 31; a strong magnet 33 is set at the bottom of the transmission rack 32.

[0030] When in use, the staff first screws one end of the drill pipe into the connecting cap 31, so that the drill pipe and the connecting cap 31 are threadedly connected, thereby facilitating the drill pipe to drive the device to move downhole; then, the device is moved into the well under the push of the drill pipe. When the liquid in the well enters, the transmission rod 30 pushes the transmission rack 32 forward due to the resistance of the liquid. The transmission gear 25 meshing with the left side of the transmission rack 32 and the transmission gear 25 meshing with the right side simultaneously rotate clockwise and counterclockwise respectively, thereby driving the square cover 20 to open outward through the connecting handle 24. At this time, the transmission rack 32 is pushed out, exposing the strong magnet 33. Figure 6 As shown, the metal fragments in the well can be adsorbed and recovered. Finally, after the adsorption is completed, the drill pipe is retracted. Under the tension of the drill pipe and the elastic force of the spring 36, the transmission rack 32 moves backward, so that the anti-drop components 2 on both sides are closed to prevent the adsorbed metal fragments from hitting the inner wall of the well and falling off. Finally, when the device is exposed to the surface of the liquid in the well, the prevention disc will recover the debris floating on the liquid surface. Finally, the device can be pulled back to the ground by the drill pipe for cleaning.
