DETAILED DESCRIPTION

[0019] It is easy to understand that, according to the technical scheme of the present application, those skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical scheme of the present application, and should not be regarded as the whole or as the limitation or restriction of the technical scheme of the present application.

[0020] According to embodiments of the present application, in combination Figures 1 to 8 is shown.

[0021] In actual operation, the existing detection equipment needs to be frequently adjusted according to the position of the detection target. Due to the adjustment of the detection position, the cable may be dragged. Since the ground in most detection scenes is not flat and smooth, there are often sand, gravel, metal debris or sharp protrusions. When the cable is dragged with the equipment, the outermost sheath layer will continuously rub against these rough surfaces. Lightly, it may cause the sheath layer to partially fluff, thin, or even partially damage. If the dragging distance is long or the frequency is high, the sheath layer may be directly scratched by sharp objects, forming an irregular break. When the sheath layer is damaged in this way, the internal structure of the cable originally wrapped tightly will gradually be exposed to the outside. The harsh environmental factors commonly existing in the detection scene will invade the cable through the damaged sheath layer, causing the exposed insulation layer to be damp and corroded, which may cause short circuit between the conductors, resulting in power interruption or sudden interruption of signal transmission of the detection equipment. At the same time, if the shielding layer is damaged and broken, the cable will lose the ability to resist external electromagnetic interference, and the detection signal will be severely disturbed by the surrounding environmental electromagnetic noise, resulting in distorted detection data, increased false alarm rate, or even inability to identify the real detection target. In order to solve this problem, the present application makes the following design on the low-loss wear-resistant cable for detection equipment.

[0022] A low-loss wear-resistant cable for detection equipment, comprising: a cable body 1, which is a flexible cable composed of a conductor, an insulation layer, a protective layer and the like, and has the core function of safely and low-lossly transmitting power or electrical signals between different devices or points. The outer wall of the cable body 1 is fixedly connected with a cable sheath layer 2, which is a protective structure wrapped around the outermost layer of the cable. The core function of the cable sheath layer 2 is to provide physical protection and environmental isolation for the core components such as the conductor, the insulation layer and the shielding layer inside the cable. It is the key barrier for the cable to resist external damage and adapt to complex use scenarios. The outer wall of the cable sheath layer 2 is provided with a limiting groove 3. The edge side of the cable sheath layer 2 is fixedly connected with a symmetrical sheath layer 4. The edge side of the limiting groove 3 is slidably connected with a limiting ball 5. The top of the limiting ball 5 is fixedly connected with an arc-shaped edge 6. The edge side of the arc-shaped edge 6 is fixedly connected with a U-shaped elastic workpiece 7. The inside of the U-shaped elastic workpiece 7 is fixedly connected with an elastic skeleton 8. The outer wall of the U-shaped elastic workpiece 7 is fixedly connected with symmetrical elastic workpieces 9. The top of the symmetrical elastic workpieces 9 is fixedly connected with a wear-resistant movable ring 10. The inside of the wear-resistant movable ring 10 is fixedly connected with a movable ring skeleton 11.

[0023] The cable sheath layer 2 is trumpet-shaped, the cable sheath layer 2 and the symmetrical sheath layer 4 are symmetrically arranged about the vertical central axis of the wear-resistant movable ring 10, the limiting grooves 3 are symmetrically arranged about the horizontal central axis of the cable sheath layer 2, the length of the limiting grooves 3 is one-tenth of the length of the cable sheath layer 2, the limiting balls 5 are located on the vertical central axis of the arc-shaped edge 6, the limiting balls 5 are semi-spherical, the diameter of the limiting balls 5 is the same as that of the limiting grooves 3, the number of the limiting grooves 3 is twice that of the limiting balls 5, the U-shaped elastic workpiece 7 and the symmetrical elastic workpiece 9 are symmetrically arranged about the vertical central axis of the wear-resistant movable ring 10, the U-shaped elastic workpiece 7 is fixedly connected with the wear-resistant movable ring 10, the U-shaped elastic workpiece 7 is made of silica gel, the silica gel is an elastic polymer material made of polysiloxane as the main component and adding reinforcing agents, vulcanizing agents and other additives, and has the flexibility of rubber and the weather resistance of inorganic materials, the U-shaped elastic workpiece 7 is symmetrically arranged about the horizontal central axis of the wear-resistant movable ring 10, the elastic skeleton 8 is made of titanium-nickel memory alloy, the titanium-nickel memory alloy is a new functional alloy composed of titanium and nickel in an atomic ratio of approximately 1:1, has the core characteristics of shape memory effect and super elasticity, can restore the preset shape under certain conditions, and has stable mechanical properties, is one of the most widely used memory alloys, and the elastic skeleton 8 plays a role of elastic support, the wear-resistant movable ring 10 is equidistantly arranged about the horizontal central axis of the cable body 1, the diameter of the wear-resistant movable ring 10 is greater than that of the cable body 1, the width of the movable ring skeleton 11 is half of that of the wear-resistant movable ring 10, and the movable ring skeleton 11 plays a supporting role.

[0024] When the detection device is in use, the cable is dragged on the ground, at this time, the wear-resistant movable ring 10 is in contact with the ground to generate friction, thereby avoiding that the cable is directly dragged on the ground, the wear-resistant movable ring 10 lifts the cable body 1, so that the cable body 1 is in a suspended state, when the cable encounters stones and other objects during the dragging process, at this time, the wear-resistant movable ring 10 is in contact with the stones, and the cable sheath layer 2 slides in the wear-resistant movable ring 10, the limiting ball 5 slides in the limiting groove 3, as the diameter of the cable sheath layer 2 becomes larger, at this time, the U-shaped elastic workpiece 7 starts to deform under the action of pressure, when the limiting ball 5 is located at the edge side of the limiting groove 3, at this time, the U-shaped elastic workpiece 7 and the cable sheath layer 2 are in a relatively static state, at this time, under the pulling force of the cable movement, the wear-resistant movable ring 10 generates friction with the stones, when the stones leave the wear-resistant movable ring 10, the next wear-resistant movable ring 10 continues to work with the stones, when the resistance of the wear-resistant movable ring 10 disappears, at this time, the elastic potential energy of the U-shaped elastic workpiece 7 starts to act, accompanied by the vibration and jumping in the cable dragging process, the U-shaped elastic workpiece 7 promotes the wear-resistant movable ring 10 to return to the initial position, and prepares for the next contact with the obstacles, when the wear-resistant movable ring 10 returns to the initial position, at this time, the limiting ball 5 is in contact with the limiting groove 3, and plays a role of resetting.

[0025] The cable sheath layer 2 is provided with a horn shape, the U-shaped elastic workpiece 7 and the wear-resistant movable ring 10, when the cable is dragged on the ground, at this time, the wear-resistant movable ring 10 is in contact with the ground, avoiding the friction between the cable and the ground, and isolating the wear from the source. The wear-resistant movable ring 10 directly receives the ground friction and replaces the cable body 1 to become the main body of loss, and also lifts the cable off the ground to form a suspension, completely avoiding the direct contact of the sheath layer with sand and sharp objects, greatly reducing the probability of sheath hair, cracking and breaking, 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 stone, at this time, the cable continues to advance, and the cable sheath layer 2 slides inside the wear-resistant movable ring 10, at the same time, the cable sheath layer 2 extrudes the U-shaped elastic workpiece 7. When the wear-resistant movable ring 10 is located at the side position, at this time, the wear-resistant movable ring 10 generates friction with the stone, and after the first wear-resistant movable ring 10 passes through the stone, the second wear-resistant movable ring 10 performs the same step, and can dynamically buffer and protect when encountering obstacles. The stone and other obstacles only contact the wear-resistant movable ring 10, and the cable sheath layer 2 can slide inside the wear-resistant movable ring 10, and the limiting ball 5 and the limiting groove 3 guide to avoid misalignment, and the horn-shaped cable sheath layer 2 extrudes the U-shaped elastic workpiece 7 to generate deformation, converting the impact into elastic buffering, which not only protects the wear-resistant movable ring 10 from being damaged by hard collision, but also prevents the sheath from being torn due to stress concentration. At the same time, under the elastic action of the U-shaped elastic workpiece 7, the U-shaped elastic workpiece 7 extrudes the cable sheath layer 2, promoting the wear-resistant movable ring 10 to return to the initial position, which can continuously cycle protection. The U-shaped elastic workpiece 7 pushes the wear-resistant movable ring 10 to accurately reset by means of elastic potential energy, and the subsequent wear-resistant movable ring 10 can relay to complete the wear-resistant task, with no protection blank period throughout the process, which can significantly prolong the service life of the cable, reduce the problems of equipment downtime, signal interference and data distortion caused by cable wear during detection operation, reduce the cost of cable replacement and equipment maintenance, adapt to the wear-resistant requirements of complex detection scenes such as field and construction site, and ensure the efficient and stable progress of detection work.

[0026] The wear-resistant movable ring 10 directly contacts with the ground and the stone, and replaces the cable sheath layer 2 to become the main body of wear and tear. Compared with the sheath layer of the cable body 1, the wear-resistant movable ring 10 can be selected from high-wear-resistant materials, and the wear-resistant life is ten times that of the ordinary sheath. The wear-resistant movable ring 10 can resist the friction of sand and stone and sharp protrusions for a long time, avoid the cable sheath layer 2 from being rough, cracking and breaking, and fundamentally prevent the internal insulation layer, shielding layer and conductor from being exposed. When the wear-resistant movable ring 10 encounters a stone, the cable does not directly collide with the stone, but converts the impact force of the stone into the elastic deformation of the U-shaped elastic workpiece 7, so that the sheath layer is not locally depressed and torn due to hard impact. The elastic reset of the U-shaped elastic workpiece 7 can ensure that the wear-resistant movable ring 10 quickly returns to the initial position after passing through the stone. Even if the wear-resistant movable ring 10 is repeatedly encountered and dragged, the wear-resistant movable ring 10 will not be misaligned, thereby realizing the continuous protection of the whole dragging process of the cable, greatly prolonging the service life of the cable body 1, and reducing the transmission loss through the cable suspension layout and the design of the limiting groove 3. On the one hand, the cable is suspended to avoid direct friction with the ground, thereby reducing the transmission performance attenuation caused by friction heat. On the other hand, the suspension state cooperates with the design of the limiting groove 3 to greatly increase the contact area of the cable and the air, thereby accelerating heat dissipation and further inhibiting the influence of heat loss on transmission. The double effects jointly realize the reduction of transmission loss. After reducing the transmission loss, the detection equipment operation can bring many key values, including ensuring the stability and accuracy of the detection signal, reducing signal attenuation and distortion caused by loss, ensuring the detection data, truly reflecting the target situation, avoiding misjudgment or omission, improving the reliability of the detection result, prolonging the effective detection distance, reducing the equipment load and energy consumption, reducing the power supply pressure during field operation, reducing the risk of data acquisition, preventing signal interruption caused by loss, preventing data loss during acquisition, reducing repeated detection work, improving overall operation efficiency, and ensuring that the detection task is pushed forward according to the plan.

[0027] The technical scope of the present application is not limited to the content in the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application. These modifications and changes should be within the protection scope of the present application.
