Description

Technical Field

[0001] The utility model belongs to the technical field of insulated cable production, and particularly relates to a cable insulation detection device. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires, and a non-conductive material such as resin, plastic, silicone rubber, and PVC is evenly and hermetically wrapped around the cable to form an insulating layer to prevent accidents such as electric leakage, short circuit, and electric shock caused by the contact between the conductor and the outside world. The cable with such an insulating layer is called an insulated cable. After the insulated cable is produced and processed, its insulation performance needs to be detected.

[0003] In the existing cable insulation detection devices, when detecting the insulation of the cable, not only the operation is inconvenient, but also the detection efficiency is low. At the same time, it is inconvenient to accurately find the damaged part of the cable. At the same time, most of the existing cable insulation detection devices are inconvenient to integrally cover and detect the surface of the cable, resulting in poor efficiency of cable insulation detection.

[0004] Therefore, a cable insulation detection device is needed to solve the problems of low detection efficiency, inconvenient accurate finding of the broken part of the cable, and inconvenient all-round coverage detection of the insulation of the cable in the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cable insulation detection device to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cable insulation detection device includes a bottom plate, and a plurality of corresponding brackets and mounting frames are fixed on the top end of the bottom plate. A positioning ring is fixed at the top end of the bracket, a rotating groove is opened on the inner wall of the positioning ring, and a plurality of rotating parts are rotatably installed on the inner wall of the rotating groove. The other ends of the rotating parts are all fixed with connecting parts, a rotating adjustment mechanism is arranged at one end of the connecting part, and a protective shell is fixed at the other end of the connecting part. An insulation detection mechanism is arranged on the inner wall of the protective shell.

[0007] The insulation detection mechanism can mainly realize the insulation detection of the cable. One end of the cable penetrates through the protective shell and is fixed to one end of the cable winder at the same time, and the other end of the cable is energized at low voltage, and then the cable is wound up. Then, through the insulation detection mechanism, the insulation of the cable can be detected.

[0008] It should be noted that in the solution, the insulation detection mechanism includes a plurality of movable slots, which are circumferentially distributed and opened on the protective shell. A reset spring is arranged on the inner wall of the movable slot, and the other end of the reset spring is fixed with a connecting block, and the other end of the connecting block is fixed with a receiving head;

[0009] The insulation detection mechanism further includes telescopic test pens, and a plurality of the telescopic test pens are circumferentially distributed and fixed on the outer wall of the protective shell.

[0010] It is further worth noting that one end of the telescopic head of the telescopic test pen penetrates through the movable slot and extends to the center of one end of the connecting block, and both the connecting block and the receiving head are made of conductive materials.

[0011] Since the connecting block and the receiving head are made of conductive materials, when the receiving head can contact the outer wall of the broken cable, the electric power of the energized cable can be transmitted to the inner wall of the telescopic test pen, so that the flashing light can flash.

[0012] It is further necessary to note that the rotation adjustment mechanism includes a worm, and the worm is fixedly installed at the top of the mounting frame;

[0013] The rotation adjustment mechanism further includes a worm gear, and one side of the worm gear is fixed to one end of a plurality of connecting pieces.

[0014] At the same time, through the action of the rotation adjustment mechanism, when the worm is rotated, it can drive the worm gear to rotate, thereby further driving the connecting piece to be stressed. Through the action of the connecting piece, it can drive the protective shell to rotate, thereby driving the insulation detection mechanism inside it to operate, enabling the receiving head to be adjusted. Through the action of the insulation detection mechanism and the ability to adjust the angle of the receiving head, the outer wall of the cable can be more comprehensively insulatedly detected, thereby improving the coverage rate of the outer wall of the cable.

[0015] As a preferred implementation manner, a limiting ring is fixedly installed at the center of the protective shell, and the receiving head penetrates through the limiting ring and is slidably limited.

[0016] As a preferred implementation manner, a cable winder is fixed at the other end of the top of the bottom plate.

[0017] When the cable is wound and one end of the cable is energized at low voltage, it fits with the insulating rubber on the outer wall of the cable. At the same time, when the cable is wound, the receiving head slides to the outer wall of the insulating rubber of the cable. When the damaged end of the outer wall of the cable fits with the receiving head, the receiving head can transmit it to the connecting block, and then the telescopic test pen can sense it, and the flashing light at the top of the telescopic test pen gives a prompt.

[0018] Compared with the prior art, a cable insulation detection device provided by the utility model has at least the following beneficial effects:

[0019] (1) Through the mutual cooperation of the protective member, the cable winder, the insulation detection mechanism, the movable groove, the return spring, the connecting block, the receiving head, and the telescopic test pen, and then applying low-voltage power to one end of the cable, it is possible to achieve that when the cable is being wound, when the outer wall of the cable is in contact with the receiving head, and when the broken side of the cable contacts the receiving head, the received power can be transmitted to the telescopic test pen through the connecting block, so as to quickly and accurately detect the insulation of the cable.

[0020] (2) Through the mutual cooperation of the rotation adjustment mechanism, the worm, and the worm wheel, it is possible to drive the protective box to rotate, thereby driving the receiving head inside it to rotate, and then adjusting the position of the receiving head. By means of multiple groups of cable insulation detection mechanisms and receiving heads, they can be more evenly distributed on the surface of the cable, so as to achieve full coverage of the cable surface and thus detect the insulation of the cable.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following further describes the utility model with reference to the embodiments.

[0027] Please refer to Figures 1-4, the present utility model provides a cable insulation detection device, including a bottom plate 1. Multiple corresponding brackets 2 and a mounting frame 8 are fixed to the top end of the bottom plate 1. A positioning ring 3 is fixed to the top end of the bracket 2. A rotating groove 4 is formed in the inner wall of the positioning ring 3. A plurality of rotating members 5 are rotatably installed in the inner wall of the rotating groove 4. The other ends of the rotating members 5 are all fixed with connecting members 6. One end of the connecting member 6 is provided with a rotation adjustment mechanism 9. The other end of the connecting member 6 is fixed with a protective shell 10. An insulation detection mechanism 12 is arranged on the inner wall of the protective shell 10.

[0028] Through the insulation detection mechanism 12, the cable can be mainly insulated and detected. One end of the cable is passed through the protective shell 10 and fixed to one end of the cable winder 7 at the same time, and the other end of the cable is energized at low voltage, and then the cable is wound up. Then, through the insulation detection mechanism 12, the insulation of the cable can be detected.

[0029] At the same time, under the action of the rotation adjustment mechanism 9, first rotate the worm 91, so as to drive the worm wheel 92 to rotate, and further drive the connecting member 6 to be stressed. Then, under the action of the connecting member 6, the protective shell 10 can be driven to rotate, so as to drive the internal insulation detection mechanism 12 to operate, and the receiving head 124 can be adjusted. Then, under the action of the insulation detection mechanism 12 and the angle of the receiving head 124 can be adjusted, so as to more comprehensively detect the insulation of the outer wall of the cable, and thus improve the coverage rate of the outer wall of the cable.

[0030] Further, as Figure 2 , Figure 3 shown, specifically, the insulation detection mechanism 12 includes a plurality of movable grooves 121, which are circumferentially distributed in the protective shell 10. A return spring 122 is arranged on the inner wall of the movable groove 121. The other end of the return spring 122 is fixed with a connecting block 123. The other end of the connecting block 123 is fixed with a receiving head 124;

[0031] The insulation detection mechanism 12 further includes a telescopic test pen 125, and a plurality of telescopic test pens 125 are circumferentially fixed to the outer wall of the protective shell 10.

[0032] When the cable is wound up and one end of the cable is energized at low voltage, the insulating rubber on the outer wall of the cable is in contact. At the same time, when the cable is wound up, the receiving head 124 slides to the outer wall of the insulating rubber of the cable. When the damaged end of the outer wall of the cable is in contact with the receiving head 124, the receiving head 124 can transmit to the connecting block 123, and then the telescopic test pen 125 can be induced. Thus, a warning is given by the flashing light at the top of the telescopic test pen 125.

[0033] Further, asFigure 3 As shown, it is worth specifically explaining that one end of the telescopic test pen 125 passes through the movable slot 121 and extends to the center of one end of the connecting block 123. Both the connecting block 123 and the receiving head 124 are made of conductive materials.

[0034] The telescopic test pen 125 can mainly achieve that when the receiving head 124 touches the surface of the damaged cable, the cable is energized at low voltage. Thus, it can be realized that the receiving head 124 conducts the electricity to the connecting block 123, and then through the connecting block 123, it can be transmitted to the telescopic test pen 125, so that the flashing light at the top of the telescopic test pen 125 flashes. Thus, it can be realized to quickly detect the cable.

[0035] This solution has the following working process: Through the insulation detection mechanism 12, it can mainly achieve the insulation detection of the cable. And by fixing the center of the protective shell 10 and the limiting ring 11 at one end of the cable to one end of the cable winder 7 at the same time, and energizing the other end of the cable at low voltage, then winding the cable, and then through the insulation detection mechanism 12, it can realize the insulation detection of the cable. At the same time, through the telescopic test pen 125, it can mainly achieve that when the receiving head 124 touches the surface of the damaged cable, it can be realized that the receiving head 124 transmits the electricity to the connecting block 123, and then through the connecting block 123, it can be transmitted to the telescopic test pen 125, so that the flashing light at the top of the telescopic test pen 125 flashes. Thus, it can be realized to quickly detect the insulation of the cable. And through the action of the rotation adjustment mechanism 9, while rotating the worm 91, it can be realized to drive the worm gear 92 to rotate. Thus, it can further realize driving the connecting member 6 to be stressed. Through the action of the connecting member 6, it can drive the protective shell 10 to rotate. Thus, it can be realized to drive the internal insulation detection mechanism 12 to operate, so that the receiving head 124 can be adjusted in angle, and then it can be realized to more comprehensively detect the outer wall of the cable, and thus improve the coverage rate of the outer wall of the cable.

[0036] According to the above working process, it can be known that through Figure 3 As shown, multiple receiving heads 124 are arranged at intervals, so that it can be realized to more comprehensively detect the outer wall of the cable. And through the action of the return spring 122, it can drive the connecting block 123 and the receiving head 124 to slide under stress, so that it can be realized to fit more closely with the outer wall of the cable, and thus can more excellently detect the insulation of the cable.

[0037] Furthermore, as Figure 1 、 Figure 2 shown, it is worth specifically explaining that the rotation adjustment mechanism 9 includes a worm 91, and the worm 91 is fixedly installed at the top of the mounting frame 8;

[0038] The rotation adjustment mechanism 9 further includes a worm gear 92, and one side of the worm gear 92 is fixed to one end of a plurality of connecting members 6.

[0039] Since the connecting block 123 and the receiving head 124 are made of conductive materials, when the receiving head 124 can contact the outer wall of the broken cable, the electric power of the energized cable can be transmitted to the inner wall of the telescopic test pen 125, so that the flashing lamp can flash.

[0040] Furthermore, as shown in Figure 1 、 Figure 3 It is worth specifically stating that a limiting ring 11 is fixedly installed at the center of the protective shell 10, and the receiving head 124 passes through the limiting ring 11 and is limited to slide.

[0041] The limiting ring 11 can mainly limit the movement of the receiving head 124, thereby improving the stability during cable winding.

[0042] Furthermore, as shown in Figure 1 、 Figure 4 It is worth specifically stating that a cable winder 7 is fixed to the other end of the top of the bottom plate 1.

[0043] When the cable winder 7 winds the cable, and the outer wall of the cable is attached to the receiving head 124, the insulation of the outer wall of the cable can be detected more excellently.

[0044] In summary: Through the mutual cooperation between a plurality of protective shells 10 and the insulation detection mechanism 12 inside them, and the receiving heads 124 between the plurality of protective shells 10 are all distributed at intervals, the broken parts of the outer wall of the cable can be comprehensively insulated and detected, and the broken parts of the cable can be accurately detected by the insulation detection mechanism 12.

[0045] The cable winder 7 and the telescopic test pen 125 can be purchased on the market. The cable winder 7 and the telescopic test pen 125 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
