[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] The present application embodiment provides a cable status early warning monitoring device, referring to Figure 1 and Figure 2 , comprising a box body 10 with openings at both ends and a hollow interior, wherein the openings at both ends of the box body 10 are connected to the inner cavity of the box body 10;

[0029] The box body 10 is provided with a first pipe 11 and a second pipe 12 for the cables to pass through. The ends of the first pipe 11 and the second pipe 12 close to each other have a receiving portion 13 for accommodating the cable connection point. The inner diameter of the receiving portion 13 of the first pipe 11 and the second pipe 12 is larger than the inner diameter of the opening parts of the first pipe 11 and the second pipe 12 close to the two ends of the box body 10. When two cables pass through the first pipe 11 and the second pipe 12 respectively, the connection point of the cables is located on the inner side of the receiving portion 13. The receiving portion 13 of the first pipe 11 is provided with a temperature detection module 34 for detecting the temperature of the cable connection point. The first pipe 11 is fixedly connected to the inner side of one of the openings of the box body 10, and the second pipe 12 is movably inserted into the inner side of the other opening of the box body 10 and the inner side of the oscillation detection circle 20. When not in an assembled state, the second pipe 12 can be axially displaced in the end opening of the box body 10.

[0030] A discharge detection ring 30 is provided between the first pipe fitting 11 and the second pipe fitting 12. Both ends of the discharge detection ring 30 are detachably connected to the first pipe fitting 11 and the second pipe fitting 12, respectively. In the assembled state, the first pipe fitting 11, the second pipe fitting 12 and the discharge detection ring 30 are connected to form a whole.

[0031] An oscillation detection ring 20 for detecting cable oscillation is also provided inside the box body 10. The oscillation detection ring 20 is located at the opening of the box body 10 where the second pipe fitting 12 is inserted. The oscillation detection ring 20 is detachably connected to the inside of the box body 10. The diameter of the opening part of the second pipe fitting 12 inserted into the box body 10 is smaller than the inner diameter of the end opening of the box body 10 where it is located. The inner side of the oscillation detection ring 20 is in close contact with the outer side of the second pipe fitting 12.

[0032] The following is a further introduction based on specific usage scenarios.

[0033] When in use, the operator first moves the second tube 12 toward the first tube 11, installs the oscillation detection ring 20 near the end of the box body 10, and then moves the second tube 12 away from the first tube 11. The second tube 12 moves axially away from the first tube 11 on the inner side of the opening at the end of the box body 10. At this time, the distance between the first tube 11 and the second tube 12 is relatively large, which allows the operator to connect cables and install detection components.

[0034] After the first pipe fitting 11 and the second pipe fitting 12 are away from each other, the operator installs the discharge detection ring 30 on the first pipe fitting 11, and then the operator passes the two cables to be connected through the first pipe fitting 11 and the second pipe fitting 12 respectively, and connects and fixes the two cables. After the two cables are connected, the operator installs the second pipe fitting 12 on the side of the discharge detection ring 30 close to the second pipe fitting 12. At this time, the connection point of the cable is located on the first pipe fitting 11, the second pipe fitting 12 accommodating portion 13 and the inner side of the discharge detection ring 30. Then the operator installs the temperature detection module 34 on the accommodating portion 13 of the first pipe fitting 11 to complete the installation.

[0035] In the embodiment of the present application, the temperature detection module 34, the oscillation detection coil 20 and the discharge detection coil 30 are detection components for detecting the cable status. The temperature detection module 34 is installed on the accommodating portion 13 of the first pipe fitting 11, the oscillation detection coil 20 is installed inside the box body 10, and the discharge detection coil 30 is installed between the first pipe fitting 11 and the second pipe fitting 12. The first pipe fitting 11 and the box body 10 are fixedly connected to form a whole. It can be found that in the embodiment of the present application, the status of the attachment to which the detection component is installed is fixed. When the operator installs the detection component, there is no need to additionally fix the detection component, which reduces the overall installation difficulty of the device and reduces the assembly process of the device.

[0036] In the embodiment of the present application, the temperature detection module 34, the oscillation detection circle 20 and the discharge detection circle 30 detection components are modularly arranged and can be detachably connected to the attachment body, which is relatively easy to install and can also be disassembled with faster efficiency during maintenance.

[0037] In general, the embodiment of the present application adopts a modular arrangement of detection components such as a temperature detection module 34, an oscillation detection circle 20 and a discharge detection circle 30, so that the detection components are installed on an attachment with a fixed shape and position through a detachable connection, thereby reducing the overall installation difficulty of the device, reducing the assembly process of the device, reducing the difficulty of disassembly during maintenance of the device, and significantly improving the efficiency of the device during installation and maintenance.

[0038] It can be found that in the embodiment of the present application, the second tube fitting 12 is located on the inner side of the oscillation detection circle 20 and the end opening of the box body 10. Since the oscillation detection circle 20 is in close contact with the outer side of the second tube fitting 12, when the cable oscillates, the cable will vibrate inside the second tube fitting 12, and the oscillation detection circle 20 will capture the vibration of the cable. That is, when the second tube fitting 12 vibrates, the oscillation detection circle 20 can infer that the cable is vibrating by capturing the vibration signal of the vibration of the second tube fitting 12, which increases the oscillation detection range and stability of the oscillation detection circle 20.

[0039] When installing the oscillation detection ring 20, the operator is required to move the second pipe fitting 12 in a direction close to the first pipe fitting 11. In a possible implementation method of the embodiment of the present application, the outer diameter of the accommodating portion 13 of the first pipe fitting 11 is smaller than the inner diameter of the accommodating portion 13 of the second pipe fitting 12, and the accommodating portion 13 of the second pipe fitting 12 can be looped around the outside of the accommodating portion 13 of the first pipe fitting 11. In this way, when the operator moves the second pipe fitting 12 in a direction close to the first pipe fitting 11, the second pipe fitting 12 can be looped around the first pipe fitting 11 to provide more workpieces for the operator to install the oscillation detection ring 20.

[0040] The discharge detection ring 30 is detachably connected between the first pipe 11 and the second pipe 12. The operator first installs the discharge detection ring 30 on the first pipe 11, and then installs the second pipe 12 on the discharge detection ring 30 in place. The discharge detection ring 30 is detachably connected to the first pipe 11 and the second pipe 12. In a possible implementation of the embodiment of the present application, a mounting hole is provided on the accommodating portion 13 of the first pipe 11, and one end of the discharge detection ring 30 close to the first pipe 11 is fixedly connected to the first connecting ring 31, and a plurality of elastic spring pieces 32 are fixedly connected to the outer side of the first connecting ring 31. When the first connecting ring 31 is inserted into the accommodating portion 13 of the first pipe 11, the spring pieces 32 outside the first connecting ring 31 are embedded in the accommodating portion 13 of the first pipe 11 by their own elastic parts. The second pipe 12 is inserted into the mounting hole, and one end of the discharge detection ring 30 close to the second pipe 12 is fixedly connected to the second connecting ring 33. An external thread is arranged on the outer side of the second connecting ring 33, and an internal thread matched with the external thread on the outer side of the second connecting ring 33 is arranged on the inner side of the accommodating portion 13 of the second pipe 12. When the second pipe 12 is sleeved on the outer side of the second connecting ring 33, the second pipe 12 is threadedly connected with the second connecting ring 33. During installation, the operator only needs to insert the first connecting ring 31 into the first pipe 11 to fix the discharge detection ring 30, and only needs to rotate the second pipe 12 to make the second pipe 12 threadedly connected with the second connecting ring 33 to install the second pipe 12. The steps for installation and disassembly are simple, which improves the efficiency of the device during installation and maintenance.

[0041] The temperature detection module 34 is installed on the top of the first pipe fitting 11 accommodating portion 13. In a possible implementation method of the embodiment of the present application, a temperature detection hole for installing the temperature detection module 34 is also opened on the top of the first pipe fitting 11 accommodating portion 13. The temperature detection module 34 is detachably connected to the temperature detection hole by screws. The temperature detection module 34 is installed on the top of the first pipe fitting 11 accommodating portion 13 by screw connection, and the installation and disassembly steps are simple.

[0042] The oscillation detection ring 20 is located at the opening of the box body 10 where the second pipe fitting 12 is inserted. In a possible implementation method of the embodiment of the present application, a plurality of clamping posts 21 are installed on the outside of the oscillation detection ring 20, and an installation groove adapted to the clamping posts 21 is provided on the inside of the box body 10. In the installed state, the clamping posts 21 are interference fit with the installation grooves, and the steps for installation and disassembly are simple, thereby improving the efficiency of the device during installation and maintenance.

[0043] As a feasible specific implementation method of the present application embodiment, refer to Figure 3 The first pipe 11 is also provided with a fixing component 35 for fixing the cable. The first pipe 11 is also provided with a long hole for installing the fixing component 35. The cables in the first pipe 11 are fixed by the fixing component 35, thereby reducing the vibration of the cables in the first pipe 11.

[0044] It should be understood that in actual applications, when there is no relative displacement between the cables inside the box body 10 and the box body 10, it should be understood that the cables inside the box body 10 have no vibration. After the cables inside the first tube 11 are fixed, the disturbance caused by the external cables is concentrated on the cables inside the second tube 12. In this way, the oscillation detection ring 20 on the outside of the second tube 12 can detect the vibration of the cables with a larger detection range.

[0045] In this embodiment, the fixing assembly 35 includes an elastic ring 36 which is ring-shaped on the outside of the first pipe 11. A plurality of pressing blocks 37 are arranged on the inside of the elastic ring 36. The pressing blocks 37 extend into the long holes. The elastic force of the elastic ring 36 allows the pressing blocks 37 to press the cables tightly, thereby reducing the vibration of the cables in the first pipe 11.

[0046] Furthermore, a shape-adjustable packaging sheet 14 is provided on the inner side of one end of the first tube 11 away from the first tube 11 accommodating portion 13. There are a plurality of packaging sheets 14, which are distributed in a circular array on the inner side of the first tube 11. The packaging sheets 14 can further fix the cables and reduce the influence of the external environment on the interior of the box body 10.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
