These devices are not conducive to real-time monitoring of cable operating conditions and are relatively unable to promptly detect cable aging and potential faults, leading to an incomplete assessment of the aging state of the cable insulation layer.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figures 1-9 This is the first embodiment of the present invention. This embodiment provides a cable aging degree detection device, which can realize non-contact and accurate detection of cable aging degree through the collaborative working mode of infrared thermal imaging detection component 102 and gas detection component 104, thereby improving the detection effect.

[0037] Specifically, the detection unit 100 includes a housing 101, an infrared thermal imaging detection component 102 disposed inside the housing 101, a heating component 103 disposed inside the housing 101, and a gas detection component 104 disposed inside the housing 101.

[0038] The winding unit 200 includes a transmission assembly 201, a rotating assembly 202 disposed on the transmission assembly 201, and a cover plate 203 detachably disposed on the rotating assembly 202.

[0039] The detection unit 100 is used to detect the degree of aging of the cable;

[0040] The winding unit 200 is used for automatically winding cables.

[0041] Furthermore, the gas detection assembly 104 includes two sets of annular frames 104a, a detection cylinder 104b sleeved inside the two sets of annular frames 104a, an air intake hole 104c disposed inside the detection cylinder 104b, and a microporous membrane 104d sleeved inside the detection cylinder 104b.

[0042] Furthermore, the gas detection assembly 104 also includes an air inlet pipe 104e inserted into the outside of the detection cylinder 104b, a filter pump 104f disposed on the air inlet pipe 104e, and an exhaust pipe 104g disposed on the filter pump 104f.

[0043] Furthermore, the heating assembly 103 includes a heating tube 103a and a fixing seat 103b sleeved on the outside of the heating tube 103a.

[0044] Furthermore, the infrared thermal imaging detection assembly 102 includes an infrared detector tube 102a, several sets of sensors 102b disposed around the infrared detector tube 102a, and two sets of ring frames 104a sleeved on the outside of the infrared detector tube 102a.

[0045] It should be noted that the infrared detection tube 102a can receive and gather the infrared radiation emitted from the cable surface to form an infrared image. The sensor on its surface enhances the detection capability of the infrared detection tube, improving image resolution and sensitivity, ensuring comprehensive and high-precision infrared thermal imaging detection. The heating tube 103a can preheat the cable, accelerating the release of gases during the aging process of the insulation material. Heat generated by the heating tube 103a increases the cable temperature, promoting gas release. It is installed at the connection point between the infrared thermal imaging detection assembly 102 and the gas detection assembly 104 via the mounting bracket 103b. The detection tube 104b in the gas detection assembly 104 collects gas samples from the environment surrounding the cable. These samples are introduced into the detection tube 104b through the microporous membrane 104d and the suction port 104c, detecting specific gases such as CO2 and SO2 released during cable aging. The microporous membrane 104d filters the gas entering the detection tube, preventing dust and other impurities from entering, thus improving detection accuracy. The filter pump 104f purifies any toxic gases detected. The gas after detection is drawn from the detection cylinder 104b into the filter pump 104f through the intake pipe 104e, and the purified gas is discharged from the exhaust pipe 104g.

[0046] In summary, the cable aging detection device of the present invention achieves comprehensive and accurate detection of cable aging through the coordinated operation of the infrared thermal imaging detection component 102 and the gas detection component 104. Firstly, the infrared thermal imaging detection component 102 can quickly and accurately acquire temperature distribution information on the cable surface, making a preliminary judgment on the cable's aging degree and localized overheating issues. The gas detection component 104 detects specific gases generated after heating the cable; changes in these gases can reflect the aging degree of the cable's internal insulation material. This comprehensive assessment of the cable's aging state from both chemical and thermal dimensions improves the accuracy and reliability of the detection results.

[0047] Example 2

[0048] Reference Figures 10-11 This is the second embodiment of the present invention. Unlike the first embodiment, it can also rewind the tested cable, thus improving the work efficiency of the staff.

[0049] Specifically, the detection unit 100 includes a housing 101, an infrared thermal imaging detection component 102 disposed inside the housing 101, a heating component 103 disposed inside the housing 101, and a gas detection component 104 disposed inside the housing 101.

[0050] The winding unit 200 includes a transmission assembly 201, a rotating assembly 202 disposed on the transmission assembly 201, and a cover plate 203 detachably disposed on the rotating assembly 202;

[0051] The detection unit 100 is used to detect the degree of aging of the cable;

[0052] The winding unit 200 is used for automatically winding cables.

[0053] Furthermore, the transmission assembly 201 includes a support base 201a, a drive wheel 201b disposed on the support base 201a, a belt 201c sleeved on the drive wheel 201b, and a driven wheel 201d sleeved on the other end of the belt 201c.

[0054] Furthermore, the rotating assembly 202 includes a rotating wheel 202a disposed on the driven wheel 201d and five sets of cylindrical rods 202b inserted onto the rotating wheel 202a.

[0055] Furthermore, it also includes a platform 300, which includes a conveying device 301 disposed on the platform 300 and a groove 302 formed on the platform 300, and the groove 302 is slidably connected to the support base 201a.

[0056] It should be noted that the platform 300 provides power and electricity to the entire device; the drive wheel 201b drives the belt 201c to rotate, and under the drive of the belt 201c, the driven wheel 201d begins to rotate. The rotating wheel 202a connects to the driven wheel 201d, and the five sets of cylindrical rods 202b are inserted into the rotating wheel 202a, so the entire rotating assembly 202 also begins to rotate. In addition, the design of the five sets of cylindrical rods 202b ensures that the cable is evenly arranged during the winding process, preventing the cable from tangling or knotting, and also facilitating the handling of the cable by the workers. The cover plate 203 adopts a detachable design, which not only protects the rotating assembly 202, but also makes it easier for workers to remove the wound cable. The support base 201a is inserted into the inner groove, so that the entire winding unit 200 moves back and forth within the groove 302, ensuring that the cable is evenly arranged during the winding process, preventing the cable from tangling or knotting, and improving the quality and stability of the winding.

[0057] In summary, this invention, by designing the winding unit 200 to move back and forth within the groove 302, not only improves the efficiency and quality of cable winding but also reduces manual intervention and prevents cable tangling or knotting. The detachable cover plate 203 not only protects the rotating component 202 but also facilitates the handling of wound cables by workers. Through the coordinated operation of these components, the stability and reliability of this device are further improved.

[0062] The detection unit 100 is used to detect the degree of aging of the cable;

[0063] The winding unit 200 is used for automatically winding cables.

[0064] Furthermore, the gas detection assembly 104 includes two sets of annular frames 104a, a detection cylinder 104b sleeved inside the two sets of annular frames 104a, an air intake hole 104c disposed inside the detection cylinder 104b, and a microporous membrane 104d sleeved inside the detection cylinder 104b.

[0066] Furthermore, the heating assembly 103 includes a heating tube 103a and a fixing seat 103b sleeved on the outside of the heating tube 103a.

[0067] Furthermore, the infrared thermal imaging detection assembly 102 includes an infrared detector tube 102a, several sets of sensors 102b disposed around the infrared detector tube 102a, and two sets of ring frames 104a sleeved on the outside of the infrared detector tube 102a.

[0068] Furthermore, the housing 101 includes an outlet end 101a, an inlet end 101b located near the infrared thermal imaging detection component 102, a brush 101c arrayed inside the inlet end 101b, a clamping component 101d located near the inlet end 101b, and a display screen 101e mounted on the housing.

[0069] Furthermore, the clamping assembly 101d includes a fixed rod 101d-1 and a rotating ball 101d-2 that is interchangeably mounted on the fixed rod; the clamping assembly 101d has 4 sets, and the included angle between each set is 90 degrees.

[0073] Preferably, the clamping assembly 101d is used to stably transport the cable to be tested into the testing unit 100; the conveying device 301 is used to accurately guide the tested cable to the winding unit 200. Furthermore, with the combined effect of both, the entire cable remains in a very stable state during testing.

[0074] In operation, the operator inserts the cable to be tested through the clamping device 101d from the inlet end into the testing unit, exiting from the outlet end on the housing. It then passes through the conveying device 301 to the winding unit 200. The device is then activated, with the platform 300 providing power to the entire unit. First, the infrared thermal imaging detection component 102 receives the infrared radiation emitted from the cable surface, forming an infrared image to assess the surface temperature distribution of the cable. Simultaneously, the heating component 103 preheats the cable, accelerating the release of gases during the aging process of the insulation material. Then, the detection cylinder 104b in the gas detection component 104 collects and analyzes specific gases in the environment surrounding the cable through the suction port 104c and the microporous membrane 104d. Finally, the test report is transmitted to the display screen 101e for analysis and reference by the operator. After testing, the cable is finally wound up by the rotating component 202.
