The anti-slip sleeve 4 can increase the contact area of the worker's hand when holding and picking up the cable, and prevent the cable from slipping and falling and being damaged. A hanging ring 5 is fixedly connected to the top of the anti-slip sleeve 4. The hanging ring 5 can provide additional support and fixing force for the cable.
[0041] Specifically, the cable core 6 is composed of multiple strands of silver-plated copper wire, each with a diameter of 0.5 mm and a total cross-sectional area of 25 square millimeters. These strands are tightly twisted together, with waterproof fibers 8 filling the center to enhance the cable's overall flexibility and waterproof performance. The shielding layer consists of a double-layer braided mesh: an outer layer of stainless steel wire braided mesh 7 and an inner layer of aluminum-magnesium alloy braided mesh 10, with gaps between the two layers for heat dissipation. The inner sheath 9 is made of polytetrafluoroethylene (PTFE) material with a thickness of 1.5 mm, possessing excellent corrosion resistance and a low coefficient of friction, effectively isolating the internal cable core 6 from external corrosive media. The outer sheath 1 is made of modified epoxy resin material with a thickness of 2 mm, exhibiting not only good corrosion resistance but also high mechanical strength and wear resistance, capable of resisting external physical damage. During production, the silver-plated copper wire is first twisted according to a specified twisting method. The cable core 6 is formed by combining the inner and outer layers of the cable core 6. Then, polytetrafluoroethylene (PTFE) material is wrapped around the cable core 6 to form a long inner sheath 9. Next, stainless steel wire braided mesh 7 and aluminum-magnesium alloy braided mesh 10 are wrapped around the outer layer to form a double shielding layer. Finally, modified epoxy resin material is wrapped around the outer layer to form the outer sheath 1. When the cable is used in deep well operations, the PTFE material of the inner sheath 9 can effectively prevent corrosive media from entering the interior, protecting the cable core 6 from damage. At the same time, the stainless steel wire braided mesh 7 and aluminum-magnesium alloy braided mesh 10 provide additional mechanical protection and electromagnetic shielding functions, ensuring the cable works normally in complex underground environments. An anti-slip sleeve 4 is fixedly connected to the front side of the outer wall of the outer sheath 1. The anti-slip sleeve 4 can increase the contact area of the worker's hands when holding and handling the cable, preventing the cable from slipping and falling and causing damage.

[0042] Reference Figure 2 , Figure 5 and Figure 6The protective mechanism 2 includes an elongated hollow plate 201, which is installed on the left and right sides of the outer wall of the outer sheath 1. Threaded rods 207 are rotatably connected to the front and rear sides of the inner wall of the left elongated hollow plate 201. A bevel gear 202 is fixedly connected to one adjacent end of the outer wall of each threaded rod 207. A fixing piece 208 is fixedly connected to the left side of the outer wall of the left elongated hollow plate 201. A fixing rod 209 is rotatably connected to the middle of the fixing piece 208, and the fixing rod 209 in the middle of the fixing piece 208 serves a rotational function. A bevel gear 204 is fixedly connected to the right side of the outer wall of the fixing rod 209, and the bevel gear 204 meshes with the bevel gear 202. Rotation of the outer wall of the fixing rod 209... The rotation of the second bevel gear 204 on the right side can drive the two first bevel gears 202 to rotate in different directions. The outer wall of the threaded rod 207 is threadedly connected to the movable plate 203. Multiple tapes 205 are equidistantly installed on the top of the long hollow plate 201. The bottom of the tapes 205 is fixedly connected to the connecting rope 206. The other end of the outer wall of the connecting rope 206 is fixedly connected to the top of the movable plate 203. The top of the outer sheath 1 is fixedly connected to the scale strip 3, which allows the staff to easily observe the length of the cable. The bottom of the outer sheath 1 is fixedly connected to the protective pad 13, which can prevent damage to the bottom of the outer sheath 1 and protect the outer sheath 1.
[0043] Specifically, rotating the fixed rod 209 drives the bevel gear 204 at the rear end of the outer wall to rotate. Since threaded rods 207 are rotatably connected to both the front and rear sides of the inner wall of the left-side elongated hollow plate 201, and bevel gears 202 are fixedly connected to adjacent ends of the threaded rods 207, with bevel gear 204 meshing with bevel gear 202, rotating the fixed rod 209 causes the bevel gear 204 to rotate synchronously, thus causing the threaded rods 207 on both sides to begin rotating. Because the outer wall of the threaded rod 207 is threadedly connected to the moving plate 203, rotating the threaded rod 207 will cause the moving plate 203 to move along the outer wall of the threaded rod 207. The cable moves back because multiple reels 205 are equidistantly installed on the top of the elongated hollow plate 201, and the bottom of each reel 205 is connected to the top of the moving plate 203 via a connecting rope 206. Therefore, when the moving plate 203 is adjusted in position by the threaded rod 207, the reels 205 will be pulled out via the connecting rope 206. The top of the outer sheath 1 is fixedly connected with a scale strip 3, which allows workers to easily observe the length of the cable. The bottom of the outer sheath 1 is fixedly connected with a protective pad 13, which can prevent damage to the bottom of the outer sheath 1 and protect the outer sheath 1.
[0044] Reference Figure 1 and Figure 2A circular handle 11 is fixedly connected to the left end of the outer wall of the fixed rod 209. The circular handle 11 can facilitate the operator to rotate the fixed rod 209 for use. A protective sleeve 12 is fixedly connected to the outer wall of the circular handle 11. The protective sleeve 12 fixedly connected to the outer wall of the circular handle 11 can protect the circular handle 11 and prevent it from being damaged.
[0045] Specifically, a circular handle 11 is fixedly connected to the left end of the outer wall of the fixed rod 209. The circular handle 11 facilitates the use of the fixed rod 209 by rotating it. A protective sleeve 12 is fixedly connected to the outer wall of the circular handle 11. The protective sleeve 12 protects the circular handle 11 and prevents it from being damaged.
[0046] Working Principle: The cable core 6 is composed of multiple strands of silver-plated copper wires, each with a diameter of 0.5mm and a total cross-sectional area of 25 square millimeters. These wires are tightly twisted together, with waterproof fibers 8 filling the center to enhance the cable's overall flexibility and waterproof performance. The shielding layer consists of a double-layer braided mesh: an outer layer of stainless steel wire braided mesh 7 and an inner layer of aluminum-magnesium alloy braided mesh 10, with gaps between the two layers for heat dissipation. The inner sheath 9 is made of polytetrafluoroethylene (PTFE) material with a thickness of 1.5mm, possessing excellent corrosion resistance and a low coefficient of friction, effectively isolating the internal cable core 6 from external corrosive media. The outer sheath 1 is made of modified epoxy resin material with a thickness of 2mm, exhibiting not only good corrosion resistance but also high mechanical strength and wear resistance, resisting external physical damage. During production, the silver-plated copper wires are first twisted according to a specified method... The cable core 6 is formed by stranding the strands together. Then, polytetrafluoroethylene (PTFE) material is wrapped around the cable core 6 to form a long strip-shaped inner sheath 9. Next, stainless steel wire braided mesh 7 and aluminum-magnesium alloy braided mesh 10 are wrapped around the outer layer to form a double shielding layer. Finally, modified epoxy resin material is wrapped around the outer layer to form an outer sheath 1. When the cable is used in deep well operations, the PTFE material of the inner sheath 9 can effectively prevent corrosive media from entering the interior and protect the cable core 6 from damage. At the same time, the stainless steel wire braided mesh 7 and aluminum-magnesium alloy braided mesh 10 provide additional mechanical protection and electromagnetic shielding functions, ensuring that the cable can work normally in complex underground environments. This avoids the problem that existing cables, although their metal sheaths can prevent physical damage, are not corrosion resistant, while composite materials have good corrosion resistance but poor temperature resistance, and anti-corrosion coatings cannot provide lasting protection due to thickness and adhesion issues, thus causing cable damage.
[0047] Rotating the fixed rod 209 causes the bevel gear 204 at the rear end of the outer wall to rotate. Since threaded rods 207 are rotatably connected to both the front and rear sides of the inner wall of the elongated hollow plate 201 on the left, and bevel gear 202 is fixedly connected to each adjacent end of the threaded rod 207, with bevel gear 204 meshing with bevel gear 202, rotating the fixed rod 209 causes bevel gear 204 to rotate synchronously, thus causing the threaded rods 207 on both sides to begin rotating. The outer wall of the threaded rod 207 is threadedly connected to the moving plate 203. Therefore, when the threaded rod 207 rotates, it will drive the movable plate 203 to move back and forth on the outer wall of the threaded rod 207. Since multiple rolls 205 are installed at equal intervals on the top of the elongated hollow plate 201, and the bottom of each roll 205 is connected to the top of the movable plate 203 through a connecting rope 206, when the movable plate 203 is adjusted in position under the drive of the threaded rod 207, it will pull the rolls 205 out through the connecting rope 206, thereby achieving the effect of supporting and protecting the outer sheath 1.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
