The cable has the characteristics of being powered inside and insulated outside. This structure is conducive to protecting the cable and extending its service life, but it still cannot completely avoid aging problems such as oxidation of the wires in the cable. Once the wires in the cable have aging problems such as oxidation, it will affect the transmission function of the line, and in severe cases, it will cause the cable to fail.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to solve the problem of low efficiency in the prior art of using relatively large machines or manual labor to perform aging detection on cables, the present invention provides a cable aging detection device.

[0026] Please refer to Figures 1 to 4 As shown, in one aspect of the technical solution applied to the present invention, the cable 1 aging detection device includes a shell body 10, a support frame 20, a lifting component 21, a temperature detector 22 and two limiting components 30; the support frame 20 is movably arranged in the through cavity 11 of the shell body 10 along the vertical direction, and the support frame 20 has an active cavity for the cable 1 to pass through; the lifting component 21 is rotatably arranged in the active cavity; the temperature detector 22 is arranged in the active cavity; the two limiting components 30 are respectively rotatably arranged in the through cavity 11 of the shell body 10 and are located on both sides of the support frame 20, the cable 1 is respectively passed through the two limiting components 30 and at least part of the cable 1 is wound around the lifting component 21, so that the lifting component 21 drives at least part of the cable 1 to move to a bending state, and the temperature detector 22 detects the outer skin temperature of the cable 1 at the bending point.

[0027] Thus, when in use, by controlling the rotation of the two limiting components 30, the two limiting components 30 pull the cable 1 to move. In this process, the support frame 20 can be controlled to move in the through cavity 11 in the vertical direction, so that the lifting component 21 drives at least part of the cable 1 to move to a bending state, and then the temperature detector 22 is used to detect the outer skin temperature of the cable 1 at the bending point in real time. When the cable 1 is bent, the contact between its internal conductor and the insulation layer will be closer, making the heat conduction faster, thereby causing the temperature at the bending point to rise, and then the aging condition of the insulation layer of the cable 1 can be detected. The efficiency and accuracy of the detection are significantly improved, and the convenience of the detection is improved, thereby solving the problem of low efficiency of aging detection of the cable 1 using larger machines or manual labor in the prior art.

[0028] In this embodiment, the temperature detector 22 is an infrared detector.

[0029] In the present application, the cable 1 aging detection device also includes a marking component 40, which is movably arranged in the through cavity 11 of the shell body 10 in the vertical direction, and is used to mark the outer skin of the cable 1 after being detected by the temperature detector 22. With such a configuration, the marking component 40 can detect that the temperature of the outer skin layer of the cable 1 is abnormally high, that is, there may be an aged or damaged part, and control the marking component 40 to move to contact the part to mark the part. This avoids the tedious process of finding the problem point again after the detection, provides accurate location information for subsequent maintenance or replacement, reduces unnecessary time and cost waste, and improves detection efficiency and accuracy.

[0030] like Figure 1 As shown, an adjusting member 23 is rotatably connected to the support frame 20, the first end of the adjusting member 23 is inserted into the shell body 10 and is threadedly connected to the first threaded hole on the shell body 10, the second end of the adjusting member 23 passes through the support frame 20 and is connected to the temperature detector 22, and a handle 24 is also provided on the first end of the adjusting member 23 to drive the adjusting member 23 to rotate so as to drive the support frame 20 to move in the vertical direction. In this embodiment, the adjusting member 23 is a threaded rod. In this way, the threaded connection between the adjusting member 23 and the shell body 10 allows the vertical movement of the support frame 20 to be accurately controlled by rotating the handle 24, so that the lifting member 21 drives at least part of the cable 1 to move to accurately adjust the bending degree of the cable 1, and the temperature detector 22 can detect the outer skin temperature of the cable 1 at the bending point in real time. This is very important for detecting the aging of the cable 1 under different bending states, because the aging degree of the cable 1 may be related to its bending state. Furthermore, by manually controlling the movement of the adjusting member 23, it is possible to adapt to cables 1 of different diameters and lengths. By adjusting the position of the supporting frame 20, it is possible to ensure that the cable 1 is in the best bending state during the detection process, so as to perform accurate aging detection.

[0031] Specifically, first sliders 25 are respectively provided on opposite sides of the support frame 20, first slide grooves 12 are respectively provided on opposite inner walls of the shell body 10, and two first sliders 25 are respectively slidably connected with two first slide grooves 12. In this way, the cooperation between the first sliders 25 and the first slide grooves 12 can provide guidance for the support frame 20, ensure its stable movement in the vertical direction, avoid the support frame 20 from deflecting or shaking during the movement, thereby ensuring the stability and accuracy of the cable 1 during the detection process.

[0032] In the present application, the limiting component 30 includes a first limiting wheel 31 and a second limiting wheel 32 arranged from top to bottom, and the cable 1 is arranged between the first limiting wheel 31 and the second limiting wheel 32. The cable 1 aging detection device also includes a first driving component 50, and the first driving component 50 is connected to the first limiting wheel 31 or the second limiting wheel 32 to drive the first limiting wheel 31 and the second limiting wheel 32 to move along the extension direction of the cable 1. In this way, the first limiting wheel 31 and the second limiting wheel 32 can fix the cable 1, ensuring that when the lifting component 21 drives at least part of the cable 1 to a bent state, the cable 1 can be stably maintained in the detection position, avoiding inaccurate detection results caused by the movement of the cable 1. In addition, when in use, through the connection between the first driving component 50 and the first limiting wheel 31 or the second limiting wheel 32, the movement of the cable 1 along its extension direction can be automatically controlled, thereby realizing aging detection of different positions of the cable 1 without manual intervention, thereby improving detection efficiency and automation.

[0033] In this embodiment, the first limiting wheel 31 and the second limiting wheel 32 are both rubber wheels, and both the first limiting wheel 31 and the second limiting wheel 32 are provided with anti-slip grooves.

[0034] like Figure 3 As shown, specifically, the first driving assembly 50 includes a first transmission wheel 51 and a first driving component 52; the first transmission wheel 51 is arranged on the rotating shaft of the first limiting wheel 31 or the second limiting wheel 32; the second transmission wheel 53 is arranged on the output shaft of the first driving component 52, and a chain 54 is wound around the first transmission wheel 51 and the second transmission wheel 53, so that the first driving component 52 drives the first limiting wheel 31 or the second limiting wheel 32 to rotate. In the above arrangement, the first driving component 52 is a driving motor. In this way, through the connection between the chain 54 and the first transmission wheel 51 and the second transmission wheel 53, power can be effectively transmitted, so that when the first driving component 52 drives the first limiting wheel 31 or the second limiting wheel 32 to rotate, the cable 1 is driven to move along its extension direction, avoiding energy loss caused by sliding friction or elastic connection, and ensuring that the output energy of the first driving component 52 can be efficiently converted into the rotation of the first limiting wheel 31 or the second limiting wheel 32.

[0035] Specifically, the second sliders 33 are respectively provided on both ends of the rotating shaft of the second limiting wheel 32, and the second slide grooves 13 are respectively provided on the two opposite inner walls of the shell body 10, and the bottoms of the two second sliders 33 are respectively connected to the two second slide grooves 13 by the first elastic member 34. In the above configuration, the first elastic member 34 is a spring. In this way, the sliding connection between the second slider 33 and the second slide groove 13 ensures the stability and guidance of the second limiting wheel 32 during the movement, and avoids the unnecessary lateral displacement of the second limiting wheel 32 when subjected to force, thereby improving the working accuracy and reliability of the entire cable 1 aging detection device. In addition, the first elastic member 34 is used to provide resistance to the downward movement of the second slider 33, so that the second limiting wheel 32 can automatically reset when not subjected to external force, thereby ensuring that when detecting cables 1 of different diameters or different conditions, the second limiting wheel 32 can adaptively adjust its position, so that the first limiting wheel 31 and the second limiting wheel 32 limit the cable 1, and automatically return to the initial position after the detection is completed, ready for the next detection.

[0036] like Figure 1 and Figure 2 As shown, the marking component 40 includes a connecting rod 41 and a marking block 42, the first end of the connecting rod 41 is rotatably connected to the marking block 42, the second end of the connecting rod 41 is inserted into the shell body 10 and is threadedly connected to the second threaded hole on the shell body 10, and the cable 1 aging detection device also includes a second drive assembly 60, the second drive assembly 60 is connected to the second end of the connecting rod 41, so as to drive the connecting rod 41 to drive the marking block 42 to move relative to the cable 1. In the above configuration, the connecting rod 41 is a threaded rod. In this way, when the temperature detector 22 detects that the outer skin temperature of a certain part of the cable 1 exceeds the preset threshold, indicating that the part may have an aging problem, the second drive assembly 60 drives the connecting rod 41 to rotate, thereby driving the marking block 42 to move in the direction toward the cable 1 until it contacts the cable 1, so as to achieve accurate marking of the aging part detected on the cable 1. This marking method is helpful for subsequent maintenance and replacement work, and there is no need to find the problem part again, which improves work efficiency. Furthermore, the rotatable connection between the connecting rod 41 and the marking block 42 enables the marking block 42 to adapt to different diameters and shapes of the cable 1 and maintain good contact and marking effects when the cable 1 is bent or the diameter changes.

[0037] In this embodiment, the marking block 42 is an arc-shaped block used to fit the outer surface of the cable 1; the marking block 42 is provided with a through hole connected to the connecting rod 41, and a sponge is provided at the bottom of the marking block 42 and inside the connecting rod 41. The sponge is used to store marking pigment, so that the connecting rod 41 can drive the marking block 42 to move toward the cable 1 until the sponge contacts the aging part on the cable 1, so as to mark the aging part of the cable 1.

[0038] Specifically, the second drive assembly 60 includes a turbine 61, a transmission rod 62 and a second drive component 65; the turbine 61 is rotatably arranged on the shell body 10, and the second end of the connecting rod 41 is inserted into the turbine 61 and threadedly connected to the turbine 61; the two ends of the transmission rod 62 are respectively provided with a worm 63 and a first bevel gear 64, and the worm 63 and the turbine 61 are meshed with each other; the output shaft of the second drive component 65 is provided with a second bevel gear 66, and the second bevel gear 66 and the first bevel gear 64 are meshed with each other, so that the second drive component 65 drives the connecting rod 41 to rotate, so as to drive the marking block 42 to perform lifting and lowering movements. In the above arrangement, the second drive component 65 is a driving motor. In this way, the second bevel gear 66 is driven to rotate by the second drive component 65, and the transmission rod 62 with the first bevel gear 64 rotates under the rotation of the second bevel gear 66, and then the connecting rod 41 connected to the marking block 42 rotates under the transmission of the turbine 61 worm 63, so as to drive the marking block 42 to move in the direction toward the cable 1 until it contacts the cable 1 for marking.

[0039] Since the worm 61 and worm 63 mechanism has a self-locking characteristic, that is, the worm 63 can easily drive the worm 61, but it is difficult for the worm 61 to reversely drive the worm 63, this characteristic is particularly important in the control of the marking component 40, which can ensure that the marking block 42 accurately marks when the cable 1 is detected to be aged, prevent the marking block 42 from sliding in an uncontrolled manner, and improve the accuracy and reliability of marking. In addition, the use of the first bevel gear 64 and the second bevel gear 66 can realize the transmission of power between different axes, so that the second drive component 65 can be arranged in a more convenient position without being restricted by the linear motion direction of the marking block 42, which is beneficial to the overall layout and space utilization of the device.

[0040] In an exemplary embodiment of the present application, a one-way bearing is provided on the output shaft of the first driving component 52, the second transmission wheel 53 is arranged on the one-way bearing, and the second bevel gear 66 is also arranged on the output shaft of the first driving component 52, so that when the output shaft of the first driving component 52 rotates in the forward direction and the reverse direction respectively, one of the second transmission wheel 53 and the second bevel gear 66 rotates, and the other does not rotate, so that the first driving component 52 drives the cable 1 to move along its extension direction and the marking component 40 to move in the direction toward the cable 1.

[0041] Specifically, a mounting frame 70 is provided on the shell body 10, and the second end of the connecting rod 41 extends into the mounting frame 70 and is rotatably connected to a blocking block 71, and the blocking block 71 is connected to the top of the mounting frame 70 through a second elastic member 72, so as to block the movement of the connecting rod 41. In the above configuration, the mounting frame 70 is an inverted U-shaped frame, and the second elastic member 72 is a spring. In this way, the second elastic member 72 is used to provide resistance to the downward movement of the connecting rod 41, and the blocking block 71 is connected to the top of the mounting frame 70 through the second elastic member 72, which can block the movement of the connecting rod 41, thereby controlling the precise position and movement stroke of the marking block 42. When the marking block 42 needs to mark the cable 1, if the marking block 42 does not have an appropriate blocking mechanism during the movement, it may cause excessive pressure on the outer skin of the cable 1 due to excessive driving force or inaccurate control, resulting in damage to the outer skin of the cable 1, and the combination of the blocking block 71 and the second elastic member 72 can prevent such overshoot phenomenon and protect the cable 1 from damage. When the marking operation is completed, the blocking block 71 can be restored to its initial position under the action of the second elastic member 72 to prevent the marking block 42 from continuing to move due to inertia or external force, thereby ensuring clear and accurate marking.

[0042] In this embodiment, a controller is also included, and the first drive component 52 or the second drive component 65 and the temperature detector 22 are respectively connected to the controller signal, and the controller stores a temperature threshold of the cable 1, so that when the temperature detector 22 detects that the temperature of the outer skin at the bending point of the cable 1 exceeds the temperature threshold, the controller sends a signal to control the first drive component 52 or the second drive component 65 to control the marking component 40 to move toward the cable 1, so as to mark the part of the cable 1 where the temperature is too high.

[0043] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0044] The cable 1 aging detection device includes a shell body 10, a support frame 20, a lifting component 21, a temperature detector 22 and two limiting components 30; the support frame 20 is movably arranged in the through cavity 11 of the shell body 10 along the vertical direction, and the support frame 20 has an active cavity for the cable 1 to pass through; the lifting component 21 is rotatably arranged in the active cavity; the temperature detector 22 is arranged in the active cavity; the two limiting components 30 are respectively rotatably arranged in the through cavity 11 of the shell body 10 and are located on both sides of the support frame 20, the cable 1 is respectively passed through the two limiting components 30 and at least part of the cable 1 is wound around the lifting component 21, so that the lifting component 21 drives at least part of the cable 1 to move to a bending state, and the temperature detector 22 detects the outer skin temperature of the cable 1 at the bending point. Thus, when in use, by controlling the rotation of the two limiting components 30, the two limiting components 30 pull the cable 1 to move. In this process, the support frame 20 can be controlled to move in the through cavity 11 in the vertical direction, so that the lifting component 21 drives at least part of the cable 1 to move to a bending state, and then the temperature detector 22 is used to detect the outer skin temperature of the cable 1 at the bending point in real time. When the cable 1 is bent, the contact between its internal conductor and the insulation layer will be closer, making the heat conduction faster, thereby causing the temperature at the bending point to rise, and then the aging condition of the insulation layer of the cable 1 can be detected. The efficiency and accuracy of the detection are significantly improved, and the convenience of the detection is improved, thereby solving the problem of low efficiency of aging detection of the cable 1 using larger machines or manual labor in the prior art.
