Description

Technical Field

[0001] This utility model relates to the field of cable insulation layer testing technology, specifically a cable insulation layer testing device. Background Technology

[0002] Cable insulation is a key component of power cables, communication cables, and signal cables. It is mainly used to isolate the conductor from the external environment, prevent current leakage, and improve the safety and durability of the cable. Cable insulation testing equipment is a device used to test the insulation performance of cables. Its main function is to detect cable insulation defects, aging, breakdown points, or potential faults, and ensure the safe operation of the cable.

[0003] A cable insulation layer detection device is described in the existing patent document with authorization announcement number CN220154306U. The described scheme initially winds the cable around the winding part of the first cable winding structure and winds the cable end around the winding part of the second cable winding structure. The winding part rotates to realize cable transmission, and the cable insulation layer is detected by the detection structure, thereby realizing efficient detection of the surface of the cable insulation layer. It can be connected to an external display device for better observation by the operator, and the detection camera can follow the horizontal position of the cable to improve the efficiency of detection.

[0004] The aforementioned technology can only inspect one side of the cable using a camera, and cannot inspect the entire cable. Since the camera can only acquire an image of one side of the cable, the back, sides, or obscured areas of the cable cannot be detected. If defects (such as cracks, wear, or bulges) appear in areas not covered by the camera, they may be overlooked, resulting in major hidden dangers going undetected. Furthermore, the aforementioned technology also has the problem of not being able to guide the cable when winding it up. If it cannot be guided, the cable will randomly pile up on the winding roller instead of being arranged neatly according to rules. Parts that are wound too tightly may be squeezed, while loose areas may be deformed or tangled together. Without guidance, the cable may twist, coil, or become twisted. Utility Model Content

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figure 1 — Figure 3As shown, a cable insulation layer testing device includes: a base plate 100, a first support plate 200, a first air expansion shaft 300, and a winding assembly. The first support plate 200 is disposed on the top of the base plate 100, and the first air expansion shaft 300 is rotatably connected to the first support plate 200. The winding assembly includes two support columns 401, which are slidably connected to both ends inside the first support plate 200. A second support plate 402 is fixedly connected between the tops of the two support columns 401. A first motor 403 is provided on one end of the second support plate 402, and a second air expansion shaft 404 is provided at the output end of the first motor 403. The first support plate 200 is provided with a counter-support. The adjustment assembly is adjusted by the support column 401. The first support plate 200 is provided with a detection assembly for detecting the cable insulation layer. The second support plate 402 is provided with a guide assembly for guiding the cable. A cable winding roller containing the cable to be tested is placed on the first air shaft 300 and then fixed by the first air shaft 300. Then, a winding roller for winding the tested cable is placed on the second air shaft 404 and fixed by the second air shaft 404. Then, one end of the cable is placed on the winding roller on the outer surface of the second air shaft 404. Then, the first motor 403 is started to drive the second air shaft 404 to rotate, thereby completing the winding of the cable.

[0030] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the adjustment assembly includes two locking screws 501, which are threaded to the upper middle part of both sides of the first support plate 200. Each of the two support columns 401 has several threaded holes 502 on one side, and the locking screws 501 are threaded to the threaded holes 502. By rotating the locking screws 501 away from the threaded holes 502, the second support plate 402 is pulled, causing the support columns 401 to slide inside the first support plate 200. After the adjustment is completed, the locking screws 501 are rotated again to bring them closer to the threaded holes 502, thereby fixing the support columns 401.

[0031] In one embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, the detection component includes a first support frame 601, which is disposed on one end of a first support plate 200. A bidirectional lead screw 602 is rotatably connected inside the first support frame 601. Two clamping plates 603 are also slidably connected inside the first support frame 601, and the threads at both ends of the bidirectional lead screw 602 are threadedly connected to the two clamping plates 603 respectively. Several spring guide pins 604 are provided on the side of the two clamping plates 603 that are close to each other. A signal receiver 605 is provided on the top of the first support frame 601, and the signal receiver 605 is electrically connected to the several spring guide pins 604. By rotating the bidirectional lead screw 602, it causes the two clamping plates 603 to move closer to each other, thereby clamping the cable and causing the spring guide pins 604 to adhere to the cable surface. If the cable insulation layer is damaged, the conductor inside the cable will come into contact with the spring guide pins 604, thereby energizing the spring guide pins 604. Subsequently, the signal receiver 605 receives the electrical signal, thereby detecting that the cable insulation is damaged.

[0032] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the guiding assembly includes a second support frame 701, which is disposed on one end of the second support plate 402. A second motor 702 is provided on one end of the second support frame 701. A reciprocating screw 703 is provided at the output end of the second motor 702. A reciprocating block 704 is provided on the reciprocating screw 703 and matches the reciprocating thread. The reciprocating block 704 is slidably connected inside the second support frame 701. A limiting rod is also provided inside the second support frame 701. The limiting rod is slidably connected to the reciprocating block 704. A first guide ring 705 is provided on one end of the reciprocating block 704. By starting the second motor 702, it drives the reciprocating screw 703 to rotate. Then, under the action of the limiting rod, it drives the reciprocating block 704 to reciprocate inside the second support frame 701.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, a support bar 801 is provided on one end of the first support plate 200, and a second guide ring 802 is provided on one end of the support bar 801 to further guide the cable.

[0034] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the ends of several spring guide pins 604 that are close to each other are all arc-shaped to prevent damage to the cable insulation layer when they come into contact with it.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, an alarm is also provided on the top of the first support frame 601. The alarm is also electrically connected to the signal receiver 605. When the signal receiver 605 receives a signal, it is then transmitted to the alarm to remind the operator.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, a turntable is provided on one end of the bidirectional lead screw 602 to facilitate the rotation of the bidirectional lead screw 602.

[0037] The above embodiment discloses a cable insulation layer testing device. A cable winding roller containing the cable to be tested is placed on a first air shaft 300 and then fixed by the first air shaft 300. A winding roller for winding the tested cable is then placed on a second air shaft 404 and fixed by the second air shaft 404. One end of the cable is then passed through a first guide ring 705 and a second guide ring 802 and placed on the winding roller on the outer surface of the second air shaft 404. The tension of the cable is then adjusted according to the different cables. The locking screw 501 can be rotated away from the threaded hole 502, and then the second support plate 402 is pulled, causing the support column 401 to slide inside the first support plate 200. After adjustment, the locking screw 501 is rotated again to bring it closer to the threaded hole 502. The perforated hole 502 secures the support column 401. Then, the first motor 403 is activated, causing the second air shaft 404 to rotate, thus completing the cable winding. Next, the bidirectional lead screw 602 is rotated, causing the two clamping plates 603 to move closer together, clamping the cable. This causes the spring guide pin 604 to adhere to the cable surface. If the cable insulation is damaged, the internal conductors of the cable will contact the spring guide pin 604, energizing it. The signal receiver 605 then receives the electrical signal, detecting the damage. During winding, the second motor 702 can also be activated, causing the reciprocating lead screw 703 to rotate. Then, under the action of the limit rod, it causes the reciprocating block 704 to reciprocate within the second support frame 701, guiding the cable.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
