Description

Technical Field

[0001] This application relates to the field of cable testing technology, and in particular to a cable testing device. Background Technology

[0002] Buried cables consist of one or more insulated conductors, primarily used for transmitting electrical energy and signals. Unlike overhead cables, buried cables are installed concealed by being buried in underground conduits. With rapid urbanization, underground cables are increasingly replacing overhead cables as the primary method of power transmission.

[0003] In related technologies, cables are laid inside pipes. Due to the limited space inside the pipes, it is necessary to use inspection equipment to move inside the pipes to inspect and maintain the cables and ensure their stable operation.

[0004] However, in related technologies, when testing equipment inspects cables inside pipes, foreign objects easily accumulate at the bottom of the pipes, causing interference to the testing equipment and affecting the accuracy of the test results. Summary of the Invention

[0005] This application provides a cable testing device to address the problem that when testing cables inside pipes, foreign objects easily accumulate at the bottom of the pipes, causing interference to the testing equipment and affecting the accuracy of the test results.

[0006] This application provides a cable testing device, including:

[0007] Matrix;

[0008] The testing mechanism includes a testing body and testing components. The testing body is mounted on a base and has a receiving space for accommodating cables. The testing components are mounted on the testing body and are used to test the surface condition of the cables.

[0009] At least two swinging mechanisms, including a first driving member and a swinging member, wherein the first driving member is disposed on the base and the swinging member is rotatably disposed on the base, and the first driving member and the swinging member are correspondingly connected;

[0010] The oscillating member is configured to rotate relative to the base under the drive of the first drive member in order to move the cable into the receiving space.

[0011] In some embodiments, the swing member is an arc shape that is recessed in a direction away from the receiving space;

[0012] The swinging component has a hinged end and a free end that are arranged opposite to each other, and the hinged end is hinged to the base.

[0013] At least two swinging members are arranged opposite each other, and the at least two swinging members arranged opposite each other are close to each other to jointly hook the cable and push the cable into the receiving space.

[0014] In some embodiments, the testing body includes an arc-shaped fixing frame, a first arc-shaped frame, and a second arc-shaped frame. The arc-shaped fixing frame is connected to the base, and the testing piece is disposed on the arc-shaped fixing frame. The first arc-shaped frame is movably disposed on the first end of the arc-shaped fixing frame, and the second arc-shaped frame is movably disposed on the second end of the arc-shaped fixing frame.

[0015] The arc-shaped fixing frame, the first arc-shaped frame, and the second arc-shaped frame together form an accommodating space; the gap between the end of the first arc-shaped frame away from the arc-shaped fixing frame and the end of the second arc-shaped frame away from the arc-shaped fixing frame constitutes a clearance gap, which is used to allow cables to enter and exit the accommodating space.

[0016] In some embodiments, a first drive gear and a second drive gear are provided on the arc-shaped fixing frame. The first drive gear and the second drive gear are arranged circumferentially along the arc-shaped fixing frame. A first arc-shaped tooth groove is provided on the outer side wall of the first arc-shaped frame. The first drive gear meshes with the first arc-shaped tooth groove to drive the first arc-shaped frame to enter and exit the arc-shaped fixing frame through the first end of the arc-shaped fixing frame. A second arc-shaped tooth groove is provided on the outer side wall of the second arc-shaped frame. The second drive gear meshes with the second arc-shaped tooth groove to drive the second arc-shaped frame to enter and exit the arc-shaped fixing frame through the second end of the arc-shaped fixing frame.

[0017] In some embodiments, the detection component includes an arc-shaped housing, a detection probe, and a second driving component. The arc-shaped housing is disposed within an arc-shaped fixed frame, the detection probe is disposed within the arc-shaped housing, and the second driving component is rotatably disposed on the arc-shaped housing. Guide rails are provided within the arc-shaped fixed frame, the first arc-shaped frame, and the second arc-shaped frame. The second driving component rolls with the guide rails to drive the arc-shaped housing to move within the arc-shaped fixed frame, the first arc-shaped frame, and the second arc-shaped frame. The detection probe is used to detect the surface condition of the cable.

[0018] In some embodiments, a moving mechanism is further included, which includes a third driving member and a rotating member. The third driving member is disposed on the base and drives the rotating member to rotate. The rotating member is used to slide with the pipeline to move the base within the pipeline.

[0019] In some embodiments, the rotating component includes a rotating wheel, and the third driving component includes a drive motor;

[0020] The base has a receiving cavity and a connecting port. The connecting port is connected to the receiving cavity. The housing of the drive motor is located inside the receiving cavity. The motor shaft of the drive motor extends out of the receiving cavity through the connecting port and is connected to the rotating wheel.

[0021] In some embodiments, the moving mechanism further includes a locking bolt and a locking nut. One end of the locking bolt is connected to the housing of the drive motor, and the other end of the locking bolt passes through a clearance hole in the base. The locking nut is threadedly connected to the locking bolt and abuts against the base to adjust the angle between the rotating wheel and the base.

[0022] In some embodiments, the base includes a body and two support rods, which are cross-connected by a hinge shaft on the body. Each support rod has a moving mechanism at its end, and an adjustment mechanism is provided between the two support rods to adjust the angle between them.

[0023] In some embodiments, there are multiple support rods, and each end of the body is provided with a hinge shaft. Each hinge shaft is provided with two support rods, and an adjustment mechanism is provided between each pair of support rods.

[0024] There are two bodies, which are hinged together by a universal joint. At least one body is equipped with a distance measuring module, which is used to detect the distance between the body and the inner wall of the pipe.

[0025] This application provides a cable testing device, comprising a base, a testing mechanism, and at least two swinging mechanisms. Through automated transport by the swinging mechanisms, the cable is lifted upwards by the swinging components into a receiving space, where it is then tested using a testing device. This eliminates the need for direct testing of the cable at the bottom of the pipe, preventing foreign objects in the pipe from affecting the test results. The receiving space of the testing body provides a fixed testing position for the cable. Combined with the precise transport by the swinging mechanisms, this ensures that each cable is within the receiving space, facilitating testing and preventing missed or false detections due to cable position deviations, thus improving the consistency and accuracy of the test results. The simultaneous operation of at least two swinging mechanisms provides more stable clamping and support for the cable compared to a single structure, preventing cable sagging or bending during transport and ensuring uniform transport speed. Both the testing mechanism and the swinging mechanisms are integrated into the base, resulting in a compact overall structure that does not require a large additional space. During testing, the cable is confined within the receiving space and cannot move freely, ensuring stable data acquisition by the testing device and further improving the reliability of the test data.

[0040] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] Buried cables consist of one or more insulated conductors, primarily used for transmitting electrical energy and signals. Unlike overhead cables, they are typically buried in underground conduits. The installation method of buried cables differs from overhead installation, achieving concealed installation through underground conduits. Due to urban land scarcity, heavy traffic, and urban beautification efforts, cities are increasingly adopting buried cables for power transmission. Compared to overhead lines, buried cables offer advantages such as smaller footprint, reliable power transmission, and stronger anti-interference capabilities.

[0043] Due to the limited space in underground pipelines, cables are laid inside the pipes, requiring inspection equipment to move within the pipeline for inspection and maintenance to ensure stable operation. This makes inspection during use very difficult. Furthermore, because they are buried underground for extended periods and the cables are often close to the bottom of the pipeline, traditional self-propelled inspection devices are easily affected by internal contaminants, leading to low inspection accuracy. Moreover, because the pipelines are buried underground, foreign objects easily accumulate at the bottom, causing interference from these objects during inspection and affecting the accuracy of the results.

[0044] In view of this, this application provides a cable testing device, which utilizes a base set inside a pipe, a testing body set on the base, and a receiving space for accommodating the cable. A testing element is set on the testing body to detect the surface condition of the cable. Two swinging mechanisms are set on the base, and the first driving members of the two swinging mechanisms are both set on the base. The first driving members drive the swinging elements to swing, so that under the action of the first driving members, the swinging elements can be driven to rotate, thereby moving the cable from the bottom of the pipe to the receiving space of the testing body for detection. The testing is then performed using the testing element. This avoids interference from foreign objects in the pipe on the testing body and facilitates the detection of the surface condition of the cable.

[0045] The cable testing device provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0046] like Figures 1 to 3 As shown, the cable testing device of this embodiment includes a base 100, a testing mechanism 200, and at least two swing mechanisms 300.

[0047] The testing mechanism 200 includes a testing body 210 and a testing element 220. The testing body 210 is disposed on the base 100 and has a receiving space 211 for accommodating the cable. The testing element 220 is disposed on the testing body 210 and is used to test the surface condition of the cable.

[0048] At least two swing mechanisms 300, including a first driving member 310 and a swing member 320, the first driving member 310 is disposed on the base 100, and the swing member 320 is rotatably disposed on the base 100, and the first driving member 310 and the swing member 320 are correspondingly connected.

[0049] The swing member 320 is configured to rotate relative to the base 100 under the drive of the first drive member 310 to move the cable to the receiving space 211.

[0050] In this application, the base 100 serves as a supporting foundation, providing a stable mounting platform for the detection mechanism 200 and the swing mechanism 300, ensuring that the positions of each component are relatively fixed and preventing overall displacement during movement. The detection body 210 is fixed on the base 100, and its internal accommodating space 211 has an opening (such as an arc-shaped groove or a semi-enclosed cavity, with the opening facing the swing mechanism 300 to facilitate cable entry). The detection element 220 is aligned with the accommodating space 211 to ensure that the surface condition of the cable can be captured after entry, thereby using the detection element 220 to detect the surface condition of the cable. At least two swing mechanisms 300 are symmetrically distributed. In the initial state, the swing element 320 is in an unfolded position away from the accommodating space 211 to avoid obstructing the initial placement of the cable. The first driving element 310 can drive the swing element 320 to swing, thereby moving the cable into the accommodating space 211.

[0051] Specifically, when it is necessary to move the cable into the receiving space 211, the first driving member 310 drives the corresponding swing member 320 to rotate on the base 100. Since at least two swing mechanisms 300 work together (such as the swing members 320 on both sides rotating synchronously towards the receiving space 211), the swing member 320 contacts the surface of the cable, and the rotation drives the cable to be smoothly transferred into the receiving space 211 of the detection machine body 210. During this process, the first driving member 310 ensures that the rotation speed of the swing member 320 is uniform and the transfer position is accurate by precisely controlling the rotation angle of the swing member 320, thus avoiding the cable from deviating or bumping into the detection machine body 210 during movement.

[0052] Once the cable is fully inside the receiving space 211, the first driving member 310 stops driving, and the swing member 320 maintains its current position. At this time, the detection member 220 detects the surface condition of the cable according to preset detection requirements. After the detection is completed, the first driving member 310 drives the swing member 320 to rotate in the opposite direction, removing the cable from the receiving space 211. Subsequently, the swing member 320 returns to its initial position.

[0053] The cable testing device provided in this application embodiment, through the automated transfer of the swing mechanism 300, allows the cable to be lifted upwards by the swinging component 320 of the swing mechanism 300 into the receiving space 211, where it is then tested using the testing component 220. The testing component 220 does not need to directly test the cable at the bottom of the pipe 10, thus avoiding the influence of foreign objects in the pipe 10 on the test results. The receiving space 211 of the testing body 210 provides a fixed testing position for the cable. Combined with the precise transfer of the swing mechanism 300, this ensures that each cable is within the receiving space 211, facilitating testing by the testing component 220 and avoiding missed or false detections due to cable position deviations, thereby improving the consistency and accuracy of the test results.

[0054] At least two swing mechanisms 300 operate synchronously, providing more stable clamping and support for the cable compared to a single structure. This prevents cable sagging and bending during transport and ensures uniform transport speed. Both the detection mechanism 200 and the swing mechanism 300 are integrated into the base 100, resulting in a compact overall structure that requires no additional space. During detection, the cable is confined within the receiving space 211 and cannot move freely, ensuring stable data acquisition by the detection component 220 and further improving the reliability of the detection data.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, the swing member 320 is an arc shape that is recessed in the direction away from the receiving space 211.

[0056] In this application, the first driving member 310 can drive the arc-shaped swing member 320 to rotate on the base 100 toward the receiving space 211. At this time, because the arc-shaped recess of the swing member 320 is oriented away from the receiving space, during the rotation, the inner side of the arc will form a close-fitting push with the cable surface. Under the constraint of the recess, the cable will not deviate due to the force applied by the swing member, but will be automatically centered by the arc structure. Compared with the planar swing member, the arc-shaped recess can disperse the pushing force, and will not cause squeezing deformation even for softer insulated cables. At the same time, the cable always moves close to the inner side of the arc during the rotation, avoiding slippage and deviation, and ensuring that it moves from the initial position into the receiving space 211.

[0057] Specifically, the arc-shaped recessed support groove structure allows the cable to fall naturally into the center of the recess when placed, achieving a centering effect, reducing the rework rate caused by inaccurate positioning, and the arc-shaped recess can also prevent the cable from slipping.

[0058] In some embodiments, the swing member 320 has a hinged end and a free end disposed opposite to each other, the hinged end being hinged to the base 100.

[0059] In this application, the hinged end of the swing member 320 is hinged to the base 100, thereby enabling the swing member 320 to rotate relative to the base 100. The free end of the swing member 320 can swing towards or away from the base 100. Under the action of the free end of the swing member 320, the cable can enter the swing member 320, so that the swing member 320 can drive the cable to move into the receiving space 211.

[0060] like Figure 1 As shown, in some embodiments, at least two swing members 320 are arranged opposite each other, and the at least two swing members 320 arranged opposite each other are close to each other to jointly hook the cable and push the cable into the receiving space 211.

[0061] In this application, at least two swing members 320 are symmetrically distributed, and each swing member 320 is provided with a hinged end and a free end. At this time, the two swing members 320 are in an open state away from each other, and the arc-shaped recesses at the free ends face each other, which facilitates the movement of the cable between the two swing members 320 when the swing members 320 swing toward the detection body 210. As the swing members 320 rotate, the arc-shaped recesses on both sides of the free ends gradually come into contact with the cable surface. When the distance between the two swing members 320 decreases to less than the cable diameter, the arc-shaped recesses abut against the cable surface.

[0062] Specifically, the first driving member 310 is disposed on the base 100, and the rotation axis of the first driving member 310 is hinged to the hinge end of the swing member 320. This allows the first driving member 310 to rotate, causing the swing member 320 to swing towards or away from the detection body 210. This switches the rotation of the motor shaft of the first driving member 310 to the swinging of the swing member 320 around the rotation axis of the first driving member 310, facilitating the use of the swing member 320 to abut against the cable and move it into the receiving space 211. Furthermore, in this application, the swing member 320 is an arc-shaped rod, with its arc-shaped recess facing away from the receiving space 211.

[0063] It should be noted that in other embodiments, a stop structure is provided on the swing member 320 to stop the cable from falling off, thus completing the hooking process. At this time, the cable is hooked and limited by the arc-shaped recesses on both sides and the two stop structures, preventing it from slipping off due to gravity or slight vibration. Once the cable has fully entered the receiving space 211, the first driving member 310 stops driving the swing member 320, and then they rotate synchronously in opposite directions, moving away from each other, releasing the cable and resetting to the initial open state, waiting for the next hooking.

[0064] like Figure 4 and Figure 5 As shown, in some embodiments, the stop structure on the swing member 320 includes a baffle 330, which is disposed on the side wall of the swing member 320 facing the receiving space 211. When the two swing members 320 hook the cable, when the swing member 320 is in contact with the cable, the baffle 330 of one swing member 320 is located on one side of the cable, and the baffle 330 of the other swing member 320 is located on the opposite side of the cable, so that both baffles 330 limit the cable.

[0065] As the swinging member 320 swings toward the detection body 210, the baffles 330 on both swinging members 320 abut against and limit the cable, thereby preventing the cable from swaying on the swinging member 320. Using the swinging member 320 in this embodiment, the movement of the cable on the swinging member 320 can be restricted, while ensuring that the cable moves into the receiving space 211 under the action of the two swinging members 320, thus allowing the detection member 220 to detect the cable within the receiving space 211.

[0066] like Figure 6 and Figure 7 As shown, in some embodiments, the detection body 210 includes an arc-shaped fixing frame 212, a first arc-shaped frame 213, and a second arc-shaped frame 214. The arc-shaped fixing frame 212 is connected to the base 100. The detection element 220 is disposed on the arc-shaped fixing frame 212. The first arc-shaped frame 213 is movably disposed on the first end of the arc-shaped fixing frame 212, and the second arc-shaped frame 214 is movably disposed on the second end of the arc-shaped fixing frame 212. The arc-shaped fixing frame 212, the first arc-shaped frame 213, and the second arc-shaped frame 214 together form a receiving space 211. The gap between the end of the first arc-shaped frame 213 away from the arc-shaped fixing frame 212 and the end of the second arc-shaped frame 214 away from the arc-shaped fixing frame 212 forms a clearance notch 215. The clearance notch 215 is used for the cable to enter and exit the receiving space 211.

[0067] In this application, the arc-shaped fixing frame 212 serves as the basic frame and is rigidly connected to the base 100, with the detection component 220 fixed inside the arc-shaped fixing frame 212. The first arc-shaped frame 213 and the second arc-shaped frame 214 are respectively movably connected to both ends of the arc-shaped fixing frame 212. In the initial state, the first arc-shaped frame 213 and the second arc-shaped frame 214 can be moved into the arc-shaped fixing frame 212 to keep the clearance notch 215 at its maximum opening, ensuring that there is no obstruction when the two swinging components 320 push the cable.

[0068] When the two swinging components 320 hook the cable and move it into the receiving space 211, the first arc frame 213 and the second arc frame 214 maintain their initial positions, and the clearance notch 215 maintains its maximum opening. When the cable enters the receiving space 211, the first arc frame 213 and the second arc frame 214 can move to protrude beyond the arc fixed frame 212. The opening of the clearance notch 215 gradually decreases as the cable enters the space. At this time, the arc fixed frame 212, the first arc frame 213, and the second arc frame 214 together form the receiving space 211, and the cable is stably confined within the receiving space 211, preventing the cable from radially shifting and ensuring that the detection component 220 can detect the surface condition of the cable.

[0069] Specifically, by adjusting the positions of the first arc frame 213 and the second arc frame 214 on the arc fixed frame 212, the size of the clearance notch 215 of the accommodating space 211 can be flexibly adapted to cables of different diameters. Compared with the traditional fixed-size accommodating space 211, there is no need to frequently replace the testing body 210, which can meet the cable testing needs of multiple fields such as power and communication.

[0070] like Figure 6 As shown, in some embodiments, a first drive gear 216 and a second drive gear 217 are provided on the arc-shaped fixing frame 212. The first drive gear 216 and the second drive gear 217 are arranged circumferentially along the arc-shaped fixing frame 212. A first arc-shaped tooth groove is provided on the outer wall of the first arc-shaped frame 213. The first drive gear 216 meshes with the first arc-shaped tooth groove to drive the first arc-shaped frame 213 to enter and exit the arc-shaped fixing frame 212 through the first end of the arc-shaped fixing frame 212. A second arc-shaped tooth groove is provided on the outer wall of the second arc-shaped frame 214. The second drive gear 217 meshes with the second arc-shaped tooth groove to drive the second arc-shaped frame 214 to enter and exit the arc-shaped fixing frame 212 through the second end of the arc-shaped fixing frame 212.

[0071] In this application, the inner side of the arc-shaped fixing frame 212 is pre-installed at a circumferential position. The first drive gear 216 and the second drive gear 217 are respectively fixed to the arc-shaped fixing frame 212 via rotating shafts. The first drive gear 216 and the second drive gear 217 are respectively connected to independent drive motors. The first arc-shaped tooth groove on the outer side wall of the first arc-shaped frame 213 meshes with the first drive gear 216, and the second arc-shaped tooth groove of the second arc-shaped frame 214 meshes with the second drive gear 217. In the initial state, the drive motor drives the first drive gear 216 and the second drive gear 217 to reverse, causing the first arc-shaped frame 213 and the second arc-shaped frame 214 to move towards the inside of the arc-shaped fixing frame 212, and then move into the arc-shaped fixing frame 212, avoiding the notch 215 and maintaining the maximum opening.

[0072] Furthermore, when the two swinging components 320 hook the cable and move it into the receiving space 211, the first drive gear 216 and the second drive gear 217 rotate under the drive of the motor. Through the meshing of the first drive gear 216 with the first arc-shaped tooth groove, the first arc-shaped frame 213 moves on the arc-shaped fixed frame 212. The second drive gear 217 meshes with the second arc-shaped tooth groove, and the second arc-shaped frame 214 moves synchronously on the arc-shaped fixed frame 212. The opening of the clearance notch 215 can be precisely adjusted by controlling the rotation angle of the first drive gear 216 and the second drive gear 217.

[0073] The first drive gear 216 drives the first arc-shaped frame 213 and the second drive gear 217 drives the second arc-shaped frame 214 to move synchronously. The arc-shaped fixed frame 212, the first arc-shaped frame 213, and the second arc-shaped frame 214 together form a receiving space 211 that fits against the cable. The self-locking property of the gear transmission keeps the positions of the first arc-shaped frame 213 and the second arc-shaped frame 214 stable, preventing the first arc-shaped frame 213 and the second arc-shaped frame 214 from shifting due to vibration during the testing process, and ensuring that the testing piece 220 is accurately aligned with the cable surface.

[0074] like Figure 6 As shown, in some embodiments, the detection element 220 includes an arc-shaped housing 221, a detection probe 222, and a second driving element 223. The arc-shaped housing 221 is disposed within the arc-shaped fixing frame 212, the detection probe 222 is disposed within the arc-shaped housing 221, and the second driving element 223 is rotatably disposed on the arc-shaped housing 221. Guide rails are provided in the arc-shaped fixing frame 212, the first arc-shaped frame 213, and the second arc-shaped frame 214. The second driving element 223 rolls with the guide rails to drive the arc-shaped housing 221 to move within the arc-shaped fixing frame 212, the first arc-shaped frame 213, and the second arc-shaped frame 214. The detection probe 222 is used to detect the surface condition of the cable.

[0075] In this application, the arc-shaped housing 221 is adapted to the curvature of the arc-shaped fixing frame 212 and is pre-installed inside the arc-shaped fixing frame 212. The detection probe 222 is disposed inside the arc-shaped housing 221, initially facing the receiving space 211 and in a standby acquisition state. The second driving member 223 is rotatably mounted on the arc-shaped housing 221 via a rotating shaft, and the second driving member 223 contacts the pre-set guide rail inside the arc-shaped fixing frame 212. After the two swinging members 320 push the cable into the receiving space 211, the first driving gear 216 and the second driving gear 217 respectively drive the first arc-shaped frame 213 and the second arc-shaped frame 214 to fully close. At this time, the guide rails inside the arc-shaped fixing frame 212, the first arc-shaped frame 213, and the second arc-shaped frame 214 are connected to form a closed annular guide rail around the cable. The second drive component 223 is now fully embedded in the closed guide rail. The second drive component 223 is activated and the guide rail rolls, causing the arc-shaped housing 221 to move at a constant speed along the annular guide rail.

[0076] Furthermore, during the movement, the arc-shaped housing 221 always conforms to the curvature of the guide rail, and the detection probe 222 moves synchronously around the cable circumference with the arc-shaped housing 221. The surface condition data collected by the detection probe 222 is transmitted to the external control system in real time, and the system simultaneously analyzes whether there are defects such as scratches, bulges, and uneven insulation layers. When the arc-shaped housing 221 drives the detection probe 222 to complete the detection, the motor of the second drive component 223 stops. Subsequently, the first drive gear 216 and the second drive gear 217 respectively drive the first arc-shaped frame 213 and the second arc-shaped frame 214 to open, the annular guide rail separates, and the second drive component 223 drives the arc-shaped housing 221 to return to the initial position along the guide rail of the arc-shaped fixed frame 212, waiting for the next detection.

[0077] Specifically, in this application, the second driving component 223 is a driving wheel. The moving detection component 220 drives the detection probe 222 to move around the entire circumference of the cable via the second driving component 223, which can accurately capture minute defects in the axial and circumferential directions of the cable. The annular guide rail formed by the closed arc-shaped fixing frame 212, the first arc-shaped frame 213, and the second arc-shaped frame 214 provides a fixed motion trajectory for the detection component 220. The rolling engagement between the second driving component 223 and the guide rail is without offset, avoiding slippage. The concentric arrangement of the arc-shaped housing 221 with the cable during movement ensures that the detection probe 222 is always aligned with the cable surface.

[0078] like Figure 1 , Figure 2 , Figure 3 as well as Figure 7As shown, in some embodiments, a moving mechanism 400 is also included. The moving mechanism 400 includes a third driving member 410 and a rotating member 420. The third driving member 410 is disposed on the base 100 and drives the rotating member 420 to rotate. The rotating member 420 is used to slide with the pipe 10 to drive the base 100 to move within the pipe 10.

[0079] In this application, the third driving member 410 is fixed on the base 100, and the rotating member 420 is connected to the output end of the third driving member 410 through a rotating shaft. Initially, the rotating member 420 is in contact with the inner wall of the pipe 10. The rotating member 420 slides against the inner wall of the pipe 10, driving the entire base 100 to move at a constant speed along the axial direction of the pipe 10. When the base 100 moves to the point where the cable needs to be inspected inside the pipe 10, the third driving member 410 decelerates and stops, while the rotating member 420 maintains a slight rotational tendency, thus maintaining contact with the inner wall of the pipe 10 and preventing the base 100 from sliding or shifting. At this time, the swing mechanism 300 and the detection mechanism 200 of the base 100 are precisely aligned with the cable to be inspected, completing the initial positioning. This facilitates the subsequent hooking of the cable into the receiving space 211 by the two swing members 320, and then the detection member 220 is used to inspect the cable in the receiving space 211. Once the cable inspection is complete and the inspection mechanism 200 is reset, the third drive component 410 is restarted, driving the rotating component 420 to move the base 100 to the position of the next cable to be inspected. Through the sliding cooperation of the rotating component 420 and the precise speed control of the third drive component 410, continuous automated inspection within the pipeline 10 can be achieved without manual intervention in the pipeline 10.

[0080] Specifically, the pipeline 10 is equipped with multiple sections of cables to be tested arranged along the axial direction of the pipeline 10. The moving mechanism 400 can drive the base 100 to move, position and test without stopping for manual adjustment. This avoids conflicts between the movement and testing process, and allows the cable to be moved within the pipeline 10 while being tested, ensuring comprehensive testing of the cable and improving testing efficiency and accuracy.

[0081] like Figure 3 and Figure 7 As shown, in some embodiments, the rotating member 420 includes a rotating wheel 421, the third driving member 410 includes a driving motor, the base 100 is provided with a receiving cavity 110 and a communicating port 120, the communicating port 120 communicates with the receiving cavity 110, the housing of the driving motor is disposed in the receiving cavity 110, and the motor shaft of the driving motor extends through the communicating port 120 to the outside of the receiving cavity 110 and is drivenly connected to the rotating wheel 421.

[0082] In this application, the housing of the third drive component 410 is fixed within the receiving cavity 110, ensuring that the motor as a whole remains secure. The connecting port 120 on the outside of the receiving cavity 110 is coaxially aligned with the motor shaft. The motor shaft of the third drive component 410 extends through the connecting port 120 to the outside of the receiving cavity 110, and the end of the motor shaft of the third drive component 410 is rigidly connected to the rotating wheel 421 via a coupling. Guided by the connecting port 120, the motor shaft precisely drives the rotating wheel 421 to rotate at high speed around its own axis. The rolling friction between the rotating wheel 421 and the inner wall of the pipe 10 is converted into axial traction force, which pulls the base 100 to move uniformly along the pipe 10. When the base 100 approaches the cable section to be tested, the drive motor decelerates, the motor shaft maintains stable output through the connecting port, the rotation speed of the rotating wheel 421 decreases, and after the base 100 stops moving, the motor maintains a low speed torque, and the rotating wheel 421 maintains slight contact with the inner wall of the pipe 10 to prevent the base 100 from sliding due to the slope or vibration of the pipe 10.

[0083] It should be noted that in this application, a guide groove is provided on the inner side wall of the pipe 10, and the rotating wheel 421 is disposed in the guide groove. The rotating wheel 421 is driven to rotate by the motor shaft of the drive motor, so that the base 100 is driven in the pipe 10, which facilitates movement in the pipe 10.

[0084] like Figure 7 As shown, in some embodiments, the moving mechanism 400 further includes a locking bolt 430 and a locking nut 440. One end of the locking bolt 430 is connected to the housing of the drive motor, and the other end of the locking bolt 430 passes through the clearance hole of the base 100. The locking nut 440 is threadedly connected to the locking bolt 430 and abuts against the base 100 to adjust the angle between the rotating wheel 421 and the base 100.

[0085] In this application, a threaded hole is pre-drilled on the outer side of the drive motor housing. One end of the locking bolt 430 is threadedly connected to the motor housing, and a clearance hole is provided at a corresponding position on the base 100. The other end of the bolt extends through the clearance hole to the outer side of the base and is threadedly connected to the locking nut 440. At this time, the motor housing rotates within the receiving cavity 110 to adjust its angle, causing the drive shaft of the drive motor to pass through the connecting port 120 and connect with the rotating wheel 421. When the drive motor housing adjusts its angle within the receiving cavity 110, the motor shaft of the drive motor, which extends out of the connecting port 120, also rotates synchronously, thereby driving the motor shaft and the rotating wheel 421 to adjust their angles synchronously. The rotating wheel 421 fits against the inner wall of the pipe 10 to avoid point contact that could cause slippage. After angle calibration, the locking nut 440 is fitted onto the locking bolt 430 and tightened, causing the locking nut 440 to slightly abut against the outer wall of the base 100, fixing the position of the motor housing and ensuring the stability of the angle of the rotating wheel 421.

[0086] Specifically, when the motor housing is installed into the receiving cavity 110, precise angle alignment is not required. Calibration can be achieved by adjusting the locking bolts 430 and 440, improving assembly efficiency and reducing maintenance costs. The locking bolts 430 and 440 only serve for angle adjustment and locking, and do not interfere with the power transmission between the motor shaft and the rotating wheel, thus improving transmission efficiency.

[0087] like Figure 1 As shown, in some embodiments, the base 100 includes a body 130 and two support rods 140. The two support rods 140 are cross-connected by a hinge shaft, which is disposed on the body 130. Each support rod 140 has a moving mechanism 400 at its end. An adjustment mechanism 150 is disposed between the two support rods 140 to adjust the angle between the two support rods 140.

[0088] In this application, the body 130 provides a fixed carrier for the detection mechanism 200 and the swing mechanism 300. Two support rods 140 are cross-connected by a hinge shaft, and a moving mechanism 400 is fixed at both ends of each support rod 140. The two ends of the adjusting mechanism 150 are hinged to the two support rods 140 respectively. When adjusting the angle, the adjusting mechanism 150 pushes the two cross-connected support rods 140 to rotate around the hinge shaft, thereby enabling the two support rods 140 to match the inner diameter of the pipe 10.

[0089] like Figure 1 and Figure 3 As shown, in some embodiments, there are multiple support rods 140, and both ends of the body 130 are provided with hinge shafts. Each hinge shaft is provided with two support rods 140, and an adjustment mechanism 150 is provided between every two support rods 140.

[0090] In this application, the adjustment mechanisms 150 at both ends of the main body 130 can be adjusted according to the change in the diameter of the pipe 10, and are adjusted and fixed in conjunction with the locking bolts 430 and locking nuts 440 of the moving mechanism 400 to prevent the moving mechanism 400 from slipping due to the deformation of the pipe 10.

[0091] It should be noted that in this application, the adjusting mechanism 150 includes a cylinder and a telescopic rod. One end of the cylinder is hinged to one of the support rods 140, one end of the telescopic rod is mounted on the cylinder, and the other end of the telescopic rod is hinged to the other support rod 140. Thus, the telescopic rod can be extended and retracted by the cylinder to adjust the angle between the two support rods 140, thereby enabling the support rod 140 to be adjusted according to the diameter of the pipe 10, adapting to pipes 10 of different diameters, and facilitating cable inspection.

[0092] like Figure 1 and Figure 3As shown, in some embodiments, there are two bodies 130, which are hinged together by a universal joint. At least one body 130 is provided with a ranging module 160, which is used to detect the distance between the body 130 and the inner wall of the pipe 10.

[0093] In this application, the two bodies 130 are hinged by a universal joint, which enables the bodies 130 to cope with the bends in the pipe 10, thereby making it easier for the inspection body 210 to cope with the complex environment of the pipe 10 and improving the practicality and reliability of the cable inspection device.

[0094] It should be noted that the ranging module 160 detects the distance between the top and bottom of the main body 130 and the pipe 10 respectively, thereby performing optical scanning and identification of the position of the entire cable detection device and the position and status of the internal cable, which can accurately determine the position of the device in real time.

[0095] Finally, it should be noted that other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the invention is limited only by the appended claims.
