Description

Technical Field

[0001] This invention relates to the field of cable technology, and in particular to a low-loss, wear-resistant cable for detection equipment. Background Technology

[0002] A cable is a flexible cable composed of a conductor, an insulation layer, a protective layer, etc. Its core function is to safely and with low loss transmit power or electrical signals between different devices or locations.

[0003] According to Chinese Patent Publication No. CN218333191U, this utility model relates to the field of cable technology and discloses a bending-resistant, wear-resistant, and low-loss cable assembly, including a cable body and an RF connector. An insulating sleeve is fixedly sleeved on the side of the cable body, a waterproof sleeve is fixedly sleeved on the side of the insulating sleeve, a protective sleeve is fixedly sleeved on the side of the waterproof sleeve, and an inner sheath is fixedly sleeved on the side of the protective sleeve. A mounting groove is circumferentially arrayed and equidistantly formed on the side of the inner sheath, and a deformation strip is provided inside the mounting groove. A constraint plate is circumferentially arrayed and equidistantly fixed on the side of the inner sheath corresponding to the deformation strip, and the constraint plate is attached to the side of the deformation strip. This utility model can withstand multiple bends without causing the outer sheath to crack. The constraint plate limits the deformation strip, and the outer wear-resistant sleeve enhances the friction on the side of the cable. When the outer wear-resistant sleeve wears, the internal wear-resistant blocks also provide wear resistance to the cable, thereby extending the service life of the cable assembly.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When existing detection equipment is used, due to the adjustment of the detection position, the cable may be dragged. During the dragging process, the cable comes into contact with the ground, which will cause the cable sheath to wear. When the sheath is damaged, the internal structure of the cable will be exposed, making it difficult to use the cable safely. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing technology has the disadvantage of cable dragging, which leads to damage to the cable sheath layer. To this end, we propose a low-loss wear-resistant cable for detection equipment.

[0006] To achieve the above objectives, this application adopts the following technical solution: a low-loss wear-resistant cable for a detection device, comprising: a cable body, a cable sheath layer fixedly connected to the outer wall of the cable body, a limiting groove formed on the outer wall of the cable sheath layer, a symmetrical sheath layer fixedly connected to the side of the cable sheath layer, a limiting ball slidably connected to the side of the limiting groove, an arc-shaped edging fixedly connected to the top of the limiting ball, a U-shaped elastic workpiece fixedly connected to the side of the arc-shaped edging, an elastic skeleton fixedly connected inside the U-shaped elastic workpiece, a symmetrical elastic workpiece fixedly connected to the outer wall of the U-shaped elastic workpiece, a wear-resistant movable ring fixedly connected to the top of the symmetrical elastic workpiece, and a movable ring skeleton fixedly connected inside the wear-resistant movable ring.

[0007] Preferably, the cable sheath layer is flared, and the cable sheath layer and the symmetrical sheath layer are symmetrically arranged about the vertical central axis of the wear-resistant moving ring.

[0008] Preferably, the limiting groove is set at an angle to the horizontal centerline of the cable sheath layer, and the length of the limiting groove is nine-tenths of the length of the cable sheath layer.

[0014] Preferably, the wear-resistant movable rings are evenly spaced about the horizontal centerline of the cable body, and the diameter of the wear-resistant movable rings is larger than the diameter of the cable body.

[0015] Preferably, the width of the movable ring skeleton is half the width of the wear-resistant movable ring, and the movable ring skeleton plays a supporting role.

[0016] The technical effects and advantages of this invention are as follows: This invention comprises a trumpet-shaped cable sheath layer, a U-shaped elastic workpiece, and a wear-resistant movable ring. When the cable is dragged on the ground, the wear-resistant movable ring contacts the ground, preventing friction between the cable and the ground. When the wear-resistant movable ring encounters a stone, the cable continues to move forward, and the cable sheath layer slides inside the wear-resistant movable ring. At the same time, the cable sheath layer squeezes the U-shaped elastic workpiece. When the wear-resistant movable ring is in the side position, friction occurs between the wear-resistant movable ring and the stone. After the first wear-resistant movable ring passes the stone, the second wear-resistant movable ring performs the same steps. Simultaneously, under the elastic action of the U-shaped elastic workpiece, the U-shaped elastic workpiece squeezes the cable sheath layer, causing the wear-resistant movable ring to return to its initial position, which helps to enhance the wear resistance of the cable and reduce cable loss.

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] According to the embodiments of the present invention, Figures 1 to 8 As shown.

[0022] In actual operation, existing detection equipment requires frequent adjustments to its placement based on changes in the target's location. These adjustments lead to cable dragging. Since most detection scenarios involve uneven surfaces, often containing sand, gravel, metal debris, or sharp protrusions, the cable's outermost sheath experiences continuous friction against these rough surfaces as it is dragged. This can cause minor issues like localized fraying and thinning of the sheath, or more serious problems such as scratches, cracks, or even partial damage. If the dragging distance is long or the frequency is high, the sheath may be directly scratched by sharp objects, creating irregular tears. Once the sheath suffers this type of damage, the original protective sheath becomes completely worn away. The internal structure of a tightly wrapped cable will gradually be exposed. Harsh environmental factors commonly found in detection scenarios can penetrate the cable through damage to the sheath, causing the exposed insulation layer to become damp and corroded. This may lead to short circuits between conductors, resulting in power outages or sudden signal transmission interruptions for the detection equipment. At the same time, if the shielding layer breaks due to damage, the cable will lose its ability to resist external electromagnetic interference. The detection signal will be severely affected by electromagnetic noise from the surrounding environment, leading to distorted detection data, increased false alarm rates, and even the inability to identify the true detection target. To solve this problem, the present invention incorporates the following design in the low-loss wear-resistant cable for detection equipment.

[0023] A low-loss, wear-resistant cable for detection equipment includes: a cable body 1, which is a flexible cable composed of a conductor, an insulation layer, and a protective layer, etc., whose core function is to safely and with low loss transmit power or electrical signals between different devices or points. A cable sheath layer 2 is fixedly connected to the outer wall of the cable body 1. The cable sheath layer 2 is a protective structure wrapped around the outermost layer of the cable, and its core function is to provide physical protection and environmental isolation for the core components inside the cable, such as the conductor, insulation layer, and shielding layer. It is the key to the cable's resistance to external damage and its adaptability to complex usage scenarios. The barrier has a limiting groove 3 on the outer wall of the cable sheath layer 2. A symmetrical sheath layer 4 is fixedly connected to the side of the cable sheath layer 2. A limiting ball 5 is slidably connected to the side of the limiting groove 3. An arc-shaped edging 6 is fixedly connected to the top of the limiting ball 5. A U-shaped elastic workpiece 7 is fixedly connected to the side of the arc-shaped edging 6. An elastic skeleton 8 is fixedly connected inside the U-shaped elastic workpiece 7. A symmetrical elastic workpiece 9 is fixedly connected to the outer wall of the U-shaped elastic workpiece 7. A wear-resistant movable ring 10 is fixedly connected to the top of the symmetrical elastic workpiece 9. A movable ring skeleton 11 is fixedly connected inside the wear-resistant movable ring 10.

[0024] The cable sheath layer 2 is flared. The cable sheath layer 2 and the symmetrical sheath layer 4 are symmetrically positioned about the vertical central axis of the wear-resistant movable ring 10. The limiting groove 3 is angled about the horizontal central axis of the cable sheath layer 2. The length of the limiting groove 3 is nine-tenths of the length of the cable sheath layer 2. The limiting ball 5 is located on the vertical central axis of the arc-shaped edge 6. The limiting ball 5 is hemispherical, and its diameter is the same as the diameter of the limiting groove 3. The number of limiting grooves 3 is twice the number of limiting balls 5. The U-shaped elastic workpiece 7 and the symmetrical elastic workpiece 9 are symmetrically positioned about the vertical central axis of the wear-resistant movable ring 10. The U-shaped elastic workpiece 7 is fixedly connected to the wear-resistant movable ring 10. The U-shaped elastic workpiece 7 is made of silicone, which is a material mainly composed of polysiloxane with added reinforcing agents and vulcanizing agents. The elastic polymer material, made with additives, combines the flexibility of rubber with the weather resistance of inorganic materials. The U-shaped elastic workpiece 7 is set at equal angles to the horizontal central axis of the wear-resistant movable ring 10. The elastic skeleton 8 is made of titanium-nickel shape memory alloy, a new type of functional alloy composed of titanium and nickel in an approximately 1:1 atomic ratio. Its core characteristics are shape memory effect and superelasticity, which can restore a preset shape under specific conditions and has stable mechanical properties. It is one of the most widely used shape memory alloys. The elastic skeleton 8 plays a role in elastic support. The wear-resistant movable rings 10 are set at equal intervals to the horizontal central axis of the cable body 1. The diameter of the wear-resistant movable ring 10 is larger than the diameter of the cable body 1. The width of the movable ring skeleton 11 is half the width of the wear-resistant movable ring 10. The movable ring skeleton 11 plays a supporting role.

[0025] When the detection equipment is in use, the cable is dragged on the ground. At this time, the wear-resistant movable ring 10 contacts the ground, generating friction to prevent the cable from dragging directly on the ground. The wear-resistant movable ring 10 lifts the cable body 1, making it suspended in the air. When the cable encounters objects such as stones during dragging, the wear-resistant movable ring 10 contacts the stone. As the cable continues to move forward, the cable sheath layer 2 slides inside the wear-resistant movable ring 10, and the limiting ball 5 slides inside the limiting groove 3. As the diameter of the cable sheath layer 2 increases, the U-shaped elastic workpiece 7 begins to deform under pressure. When the limiting ball 5 is located at the outermost side of the limiting groove 3, the U-shaped... The elastic workpiece 7 and the cable sheath layer 2 are in a relatively static state. At this time, under the tension of the moving cable, the wear-resistant movable ring 10 and the stone are in friction. When the stone leaves the wear-resistant movable ring 10, the next wear-resistant movable ring 10 continues to work with the stone. When the resistance of the wear-resistant movable ring 10 disappears, the elastic potential energy of the U-shaped elastic workpiece 7 begins to take effect. With the vibration and jumping during the cable dragging process, the U-shaped elastic workpiece 7 causes the wear-resistant movable ring 10 to return to the initial position, preparing for the next contact with the obstacle. When the wear-resistant movable ring 10 returns to the initial position, the limiting ball 5 contacts the limiting groove 3, which plays a role in resetting.

[0026] The cable is equipped with a trumpet-shaped cable sheath layer 2, a U-shaped elastic workpiece 7, and a wear-resistant movable ring 10. When the cable is dragged on the ground, the wear-resistant movable ring 10 contacts the ground, preventing friction between the cable and the ground and isolating wear at the source. The wear-resistant movable ring 10 directly bears the ground friction, replacing the cable body 1 as the main source of loss, and also lifts the cable off the ground to create a suspension, completely preventing the sheath layer from directly contacting sand, gravel, or sharp objects, greatly reducing the probability of sheath fraying, cracking, and tearing, and preventing the internal insulation layer, shielding layer, and conductor from being exposed due to sheath damage. When the wear-resistant movable ring 10 encounters a rock, the cable continues to move forward, and the cable sheath layer 2 slides inside the wear-resistant movable ring 10. At the same time, the cable sheath layer 2 squeezes the U-shaped elastic workpiece 7. When the wear-resistant movable ring 10 is in the side position, friction is generated between the wear-resistant movable ring 10 and the rock. After the first wear-resistant movable ring 10 passes the rock, the second wear-resistant movable ring 10 performs the same steps. It can dynamically buffer and protect against obstacles such as rocks. The object only contacts the wear-resistant movable ring 10. The cable sheath layer 2 can slide within the wear-resistant movable ring 10. With the help of the limiting ball 5 and the limiting groove 3, misalignment is avoided. At the same time, the trumpet-shaped cable sheath layer 2 squeezes the U-shaped elastic workpiece 7 to deform, converting the impact into elastic buffer. This protects the wear-resistant movable ring 10 from damage caused by excessive impact and prevents the sheath from tearing due to stress concentration. Meanwhile, under the elastic action of the U-shaped elastic workpiece 7, the U-shaped elastic workpiece 7 squeezes the cable sheath layer 2, causing the wear-resistant movable ring 10 to return to its initial position. This provides continuous cyclic protection. The U-shaped elastic workpiece 7 uses its elastic potential energy to push the wear-resistant movable ring 10 to accurately reset. Subsequently, the wear-resistant movable ring 10 can take over to complete the wear-resistant task. There is no protection gap throughout the process, which can significantly extend the service life of the cable, reduce equipment downtime, signal interference, and data distortion caused by cable wear during detection operations, reduce cable replacement and equipment maintenance costs, adapt to the wear-resistant requirements of complex detection scenarios such as field and construction sites, and ensure the efficient and stable progress of detection work.

[0027] The wear-resistant movable ring 10 directly contacts the ground and stones, replacing the cable sheath layer 2 as the main wear-prone element. Compared to the sheath layer of the cable body 1, the wear-resistant movable ring 10 can be made of highly wear-resistant material, with a wear life ten times that of ordinary sheaths. It can withstand the friction of sand and sharp protrusions for a long time, preventing the cable sheath layer 2 from fraying, cracking, and breaking. It fundamentally prevents the internal insulation layer, shielding layer, and conductor from being exposed. When the wear-resistant movable ring 10 encounters stones, the cable does not directly collide with the stones, but instead converts the impact force of the stones into the elastic deformation of the U-shaped elastic workpiece 7. To prevent localized dents and tears in the sheath layer due to hard impacts, the elastic reset of the U-shaped elastic workpiece 7 ensures that the wear-resistant movable ring 10 quickly returns to its initial position after passing over stones. Even with repeated obstacles and dragging, the wear-resistant movable ring 10 will not become misaligned, achieving continuous protection for the cable throughout the entire dragging process and significantly extending the service life of the cable body 1. The suspended cable layout and the design of the limiting groove 3 reduce transmission loss. On the one hand, the suspended cable avoids direct friction with the ground, reducing transmission performance degradation caused by frictional heat. On the other hand… In terms of the suspended state combined with the design of the limiting groove 3, the contact area between the cable and the air is greatly increased, accelerating heat dissipation and further suppressing the impact of heat loss on transmission. The dual effect works together to reduce transmission loss. After reducing transmission loss, it can bring several key benefits to the operation of detection equipment. First, it ensures stable and accurate detection signals, reduces signal attenuation and distortion caused by loss, ensures that the detection data truly reflects the target situation, avoids misjudgment or omission, and improves the reliability of detection results. Second, it extends the effective detection distance. After the loss is reduced, the signal can be transmitted over a longer distance in the cable, eliminating the need to frequently add signal relay equipment, expanding the detection operation range, especially suitable for large-scale field exploration scenarios. Third, it reduces equipment load and energy consumption. Smooth signal transmission can avoid the equipment from consuming extra energy due to compensation for loss, reducing the burden on the power module, extending the equipment's endurance, and reducing the power supply pressure during field operations. Fourth, it reduces data acquisition risks, avoids signal interruption caused by loss, prevents data loss during acquisition, reduces repeated detection work, improves overall operation efficiency, and ensures that the detection mission proceeds as planned.

[0028] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
