Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a mud-resistant cable. Background Technology

[0002] Mud-resistant cables are special cables designed and manufactured specifically for use in harsh environments containing mud and related corrosive media. Through special material selection, structural design and process treatment, they can effectively resist the erosion of mud and its chemical additives, while maintaining stable electrical performance, mechanical performance and structural integrity, ensuring reliable execution of power transmission, signal transmission or control commands.

[0003] However, although mud-resistant cables are wrapped with special materials to achieve mud resistance, they are still prone to damage due to continuous erosion, wear or penetration of mud when immersed in mud for a long time. The limitation of the existing cable design is that it lacks an active protection mechanism that can remove itself from the mud environment. It relies solely on the material's own resistance to resist the impact of mud. This makes it difficult for its mud resistance performance to meet the needs of long-term and extreme working conditions, and it is easy for the cable to fail due to the gradual decay of its protective ability.

[0004] To address the aforementioned problems, this application proposes a mud-resistant cable. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a mud-resistant cable, which features the ability to actively remove the cable body from the mud environment, enhance long-term resistance to mud erosion, and extend its service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mud-resistant cable, comprising a cable, wherein a mud-resistant protective sleeve is provided on the outer surface of the cable, and the outer surface of the mud-resistant protective sleeve is provided with equally spaced sliding grooves, and a sliding sleeve is slidably connected inside two sets of sliding grooves. The inner wall of the sliding sleeve is in contact with the outer surface of the mud-resistant protective sleeve, and a rotating collar is fixedly connected to the outer surface of the sliding sleeve. A threaded sleeve is provided on the outer surface of the rotating collar, and a threaded rod is threadedly connected to the inner wall of the threaded sleeve. The top end of the threaded rod is fixedly connected to the outer surface of the outer ring of the rotating collar.

[0007] As a preferred embodiment of this utility model, the left and right ends of the mud-resistant protective sleeve are both fixedly connected with fixing rings, and the inner wall of each fixing ring is fixedly connected to the outer surface of the cable.

[0008] As a preferred embodiment of this utility model, two auxiliary rings are fixedly connected to the outer surface of the sliding sleeve, and each auxiliary ring has anti-slip holes arranged at equal intervals on its outer surface.

[0009] As a preferred embodiment of this utility model, both sides of the inner ring of the rotating collar are fixedly connected with reinforcing rings, and the inner wall of each reinforcing ring is fixedly connected to the outer surface of the sliding sleeve.

[0010] As a preferred embodiment of this utility model, a reinforcing ring is fixedly connected to the outer surface of the threaded rod, and the upper surface of the reinforcing ring is fixedly connected to the outer surface of the outer ring of the rotating collar.

[0011] As a preferred embodiment of this utility model, a rotating ring is fixedly connected to the outer surface of the threaded sleeve, and rubber strips arranged at equal intervals are fixedly connected to the outer surface of the rotating ring.

[0012] As a preferred embodiment of this utility model, a support frame is fixedly connected to the bottom surface of the threaded sleeve, and the support frame has fixing holes arranged at equal intervals inside.

[0013] As a preferred embodiment of this utility model, two fixing pins are provided on the upper part of the support frame, and the bottom end of each fixing pin passes through two corresponding fixing holes and extends to the lower part of the support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a sliding sleeve, a rotating collar, a threaded sleeve, and a threaded rod, the relative position of the cable body and the installation foundation can be adjusted by using threaded transmission, realizing fine-tuning of the cable height in the mud environment, reducing the direct contact area with the mud, and forming the first protective barrier with the mud-resistant protective sleeve. Combined with the sliding cooperation of the sliding groove and the sliding sleeve, the position of the support point can be flexibly adjusted to adapt to the mud depth under different working conditions, thus improving the cable's impact resistance and displacement resistance in the mud environment. By combining active position adjustment and passive protection enhancement, this invention solves the problem that existing cables rely solely on material durability and are prone to performance degradation due to long-term immersion, significantly extending the service life of the cable in harsh mud environments.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a mud-resistant cable, including a cable 1, a mud-resistant protective sleeve 2 provided on the outer surface of the cable 1, sliding grooves 17 arranged at equal intervals on the outer surface of the mud-resistant protective sleeve 2, a sliding sleeve 3 slidably connected inside the two sets of sliding grooves 17, the inner wall of the sliding sleeve 3 contacting the outer surface of the mud-resistant protective sleeve 2, a rotating collar 5 fixedly connected to the outer surface of the sliding sleeve 3, a threaded sleeve 10 provided on the outer surface of the rotating collar 5, a threaded rod 16 threadedly connected to the inner wall of the threaded sleeve 10, and the top end of the threaded rod 16 fixedly connected to the outer surface of the outer ring of the rotating collar 5;

[0025] In this embodiment, the mud-resistant protective sleeve 2 is made of ultra-high molecular weight polyethylene. This material has excellent wear resistance, chemical corrosion resistance and low coefficient of friction, which can effectively resist the scouring and wear of sand and gravel particles in the mud. At the same time, it has good resistance to acid and alkali components, oil and other media in the mud, which can significantly improve the long-term stability of the protective sleeve in the harsh mud environment and provide reliable protection for the internal cable 1.

[0026] Specifically, the left and right ends of the mud-resistant protective sleeve 2 are fixedly connected with fixing rings 4. The inner wall of each fixing ring 4 is fixedly connected to the outer surface of the cable 1. In this embodiment, the fixing rings 4 are double-fixed to the cable 1 and the mud-resistant protective sleeve 2, which can form a rigid limit at both ends of the protective sleeve, preventing the protective sleeve from becoming loose or curled at the ends due to mud erosion or slight displacement of the cable 1 during long-term use. At the same time, it enhances the overall bonding strength between the protective sleeve and the cable 1, preventing mud from seeping in from the gap between the two.

[0027] Specifically, two assist rings 6 are fixedly connected to the outer surface of the sliding sleeve 3. Each assist ring 6 has anti-slip holes 7 arranged at equal intervals on its outer surface. In this embodiment, the assist rings 6 provide a force point for adjusting the position of the sliding sleeve 3. The anti-slip holes 7 increase the friction between the hand or tool and the assist rings 6, making it easier for the operator to push the sliding sleeve 3 along the sliding groove 17 more stably and effortlessly in the mud environment, thus improving the convenience and accuracy of position adjustment.

[0028] Specifically, reinforcing rings 8 are fixedly connected to both sides of the inner ring of the rotating collar 5. The inner wall of each reinforcing ring 8 is fixedly connected to the outer surface of the sliding sleeve 3. In this embodiment, the connection between the rotating collar 5 and the sliding sleeve 3 is extended from a single side to a two-sided reinforcement support through the reinforcing rings 8, which disperses the radial force generated during threaded transmission, prevents the connection between the rotating collar 5 and the sliding sleeve 3 from cracking or loosening due to long-term stress, and enhances the load-bearing capacity of the overall structure.

[0029] Specifically, a reinforcing ring 9 is fixedly connected to the outer surface of the threaded rod 16. The upper surface of the reinforcing ring 9 is fixedly connected to the outer surface of the outer ring of the rotating collar 5. In this embodiment, the reinforcing ring 9 increases the contact area between the threaded rod 16 and the rotating collar 5, and evenly transmits the axial force on the threaded rod 16 to the rotating collar 5, avoiding deformation or breakage of the connection point due to excessive local force, thereby improving the stability and service life of the threaded transmission structure.

[0030] Specifically, a rotating ring 11 is fixedly connected to the outer surface of the threaded sleeve 10, and rubber strips 12 arranged at equal intervals are fixedly connected to the outer surface of the rotating ring 11. In this embodiment, the rotating ring 11 provides a convenient force application structure for the rotation operation of the threaded sleeve 10. The rubber strips 12 increase the friction between the hand and the rotating ring 11. At the same time, the rubber strips 12 have a certain elasticity, which can alleviate hand discomfort during operation and make the thread adjustment process more effortless and less prone to slippage.

[0031] Specifically, a support frame 14 is fixedly connected to the bottom surface of the threaded sleeve 10. The support frame 14 has equidistantly arranged fixing holes 13 inside. In this embodiment, the support point of the cable 1 is extended to surface contact through the support frame 14, which enhances the stability of the overall structure at the bottom of the mud or on the installation foundation. The multiple fixing holes 13 provide multiple positions for fixing the support frame 14, which can be adapted to the fixing needs of different installation scenarios.

[0032] Specifically, two fixing pins 15 are provided on the upper part of the support frame 14. The bottom end of each fixing pin 15 passes through the corresponding two fixing holes 13 and extends to the lower part of the support frame 14. In this embodiment, the fixing pins 15 are connected to the installation foundation through the fixing holes 13, which can firmly fix the support frame 14 and prevent the cable 1 from being displaced under the impact of mud or external force. At the same time, the setting of double pins further improves the reliability of fixing and avoids the shaking or loosening that may occur with single-point fixing.

[0033] The working principle and usage process of this utility model are as follows: First, based on the depth of the mud environment and installation requirements, the sliding sleeve 3 is moved along the sliding groove 17 on the outer surface of the mud-resistant protective sleeve 2 by the assist ring 6. Then, in conjunction with the rotation of the rotating collar 5, the position of the sliding sleeve 3 and its connected structure is precisely adjusted so that the support frame 14 is in the appropriate support position. Subsequently, the support frame 14 is placed on the installation foundation, and a fixing hole 13 matching the foundation fixing structure is selected. The fixing pin 15 is passed through the fixing hole 13 and inserted into the preset hole position of the installation foundation, thus completing the firm fixation of the support frame 14 and effectively preventing the overall structure from shifting under the impact of mud. When it is necessary to adjust the relative position of the cable 1 and the mud surface to reduce contact, the outer surface of the rotating ring 11 is used to adjust the position of the cable 1. The rubber strip 12 applies force to rotate the threaded sleeve 10. Utilizing its threaded engagement with the threaded rod 16, it drives the rotating collar 5 and sliding sleeve 3 to rise and fall axially, thereby flexibly adjusting the height of the cable 1 and achieving the effect of actively detaching from the mud environment. During operation, the mud-resistant protective sleeve 2, thanks to the excellent properties of ultra-high molecular weight polyethylene, can effectively resist the abrasion of sand and gravel in the mud and the erosion of chemicals. The fixing ring 4 can prevent the end of the protective sleeve from loosening and block mud from seeping in. The reinforcing ring 8 and the strengthening ring 9 respectively enhance the connection strength between the rotating collar 5 and the sliding sleeve 3, and between the threaded rod 16 and the rotating collar 5, ensuring the stability and reliability of the threaded transmission and support structure. If the position needs to be adjusted again, the above-mentioned movement operation of the sliding sleeve 3 and rotation operation of the threaded sleeve 10 can be repeated.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
