It is used to transmit electricity or information from one place to another. It has the functions of carrying current, transmitting signals and energy, etc.

[0003] At present, most of the existing cable insulation layer damage detection equipment adopts the method of locating and maintaining the damaged parts of the cable insulation layer to reduce the dangers caused by the cable during use. For example, an overhead cable insulation layer damage detection equipment disclosed in announcement number CN117665646A can transmit current through annular magnetic fluid to achieve the effect of reducing danger.

[0004] As described in the above application documents, most of the existing cable insulation layer damage detection equipment requires a relatively high cost to purchase. Therefore, when the cable needs to be replaced and maintained in daily household life, the replaced cable is often only observed by the naked eye to determine whether the insulation layer on the cable surface is damaged. Since the length of a single cable is often long, the user needs to spend a long time inspecting and maintaining the cable surface, which is more troublesome. In addition, some damaged parts may be on the opposite side of the naked eye observation range, resulting in the user not checking them in time, which may lead to danger during use. Therefore, a cable insulation layer damage detection device is needed. Utility Model Content

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0033] See also Figure 1 and Figure 2 The present embodiment is a cable insulation layer damage detection device, comprising a base plate 1, the top and bottom of the base plate 1 are both horizontal planes, and the horizontal setting ensures that the bottom end of the base plate 1 can be easily placed on a desktop or the ground, and the top of the base plate 1 is fixedly connected to a mounting plate 2, and the number of mounting plates 2 is set to two, and the right end of the right mounting plate 2 is fixedly connected to a motor body 4, and the bottom end of the motor body 4 is provided with a baffle fixedly connected to the right end of the right mounting plate 2, and the output shaft of the motor body 4 passes through the inner wall of the mounting plate 2 and is fixedly connected to a winding rod 5, and the winding rod 5 is in the shape of a cylinder.

The position setting of the clamp 6 ensures that the protruding part of the clamp 6 is not easy to affect the winding of the cable.

[0034] See also Figure 1 , Figure 2 and Figure 4 The bottom plate 1 is provided with a detection mechanism 7 at the top end of the front end of the mounting plate 2. The detection mechanism 7 includes a positioning block 71. The bottom end of the positioning block 71 is fixedly connected to the top end of the bottom plate 1. A through hole with a diameter larger than the cable diameter is opened in the middle of the positioning block 71. The through hole is set to ensure that the cable can pass through the through hole, so that the outer area of ​​the positioning block 71 can achieve the positioning effect. The bottom plate 1 is fixedly connected with a detection plate 72 at the top end of the rear end of the positioning block 71. A through hole with a diameter larger than the cable diameter is opened in the middle of the upper side of the front end of the detection plate 72, and the height of the detection plate 72 is higher than the height of the positioning block 71. The height difference between the positioning block 71 and the detection plate 72 is set to ensure that the cable has a certain degree of bending deformation when entering the through hole opened in the detection plate 72, so that the degree of damage at the damaged part can be enlarged, which is convenient for detection, and the bending amplitude is small, which does not affect the normal use of the cable.

[0035] See also Figure 4 - Figure 6The inner wall of the detection plate 72 is penetrated by and slidably connected with a moving rod 73. The number of moving rods 73 is set to be several, and the several moving rods 73 are in a circular array. The inner wall of the moving rod 73 near the middle of the detection plate 72 is rotatably connected with a roller 74. The setting of the roller 74 ensures that when the cable is moving, it is not easy to be unable to move due to the friction of the moving rod 73. The inner wall of the detection plate 72 is provided with a working chamber 75, and the shape of the working chamber 75 is annular. The end of the moving rod 73 away from the roller 74 is elastically connected to the inner wall of the working chamber 75 by a spring 76. One end of the spring 76 is fixedly connected to the end of the moving rod 73 away from the roller 74, and the other end of the spring 76 is fixedly connected to the inner wall of the working chamber 75. The rear end of the moving rod 73 is fixedly connected with a control block 77, and the inner wall of the working chamber 75 is slidably connected with a moving Ring 78, the front end of the moving ring 78 is fixedly connected with a pressure block 79, the cross-sectional shapes of the control block 77 and the pressure block 79 are both right-angled trapezoids, and the cross-sectional shape of the control block 77 and the pressure block 79 after the inclined surfaces are fitted is approximately rectangular, through the shape setting of the control block 77 and the pressure block 79, it is ensured that when the control block 77 is displaced in the left and right or up and down directions, the pressure block 79 can be driven by the inclined surface to produce a front and back displacement, thereby driving the moving ring 78 to move and achieve the expected effect, the rear end of the moving ring 78 is elastically connected to the inner wall of the working bin 75 by spring 2 710, one end of the spring 2 710 is fixedly connected to the rear end of the moving ring 78, and the other end of the spring 2 710 is fixedly connected to the inner wall of the working bin 75, and the inner wall of the working bin 75 at the rear end of the moving ring 78 is provided with a motor switch 8, and when the motor switch 8 is pressed, the motor body 4 is closed.

[0036] See also Figure 1 - Figure 3 The interior of the mounting plate 2 and the front end of the winding rod 5 are jointly provided with an auxiliary component 9, the auxiliary component 9 includes a mounting groove 91, the shape of the mounting groove 91 is similar to the shape formed by connecting two cylinders, the mounting groove 91 is opened on the inner wall of the left mounting plate 2, the inner wall of the mounting groove 91 and the outer wall of the winding rod 5 are fixedly connected with a gear 1 92, the inner wall of the mounting plate 2 is rotatably connected with a reciprocating screw rod 93, the leftmost end of the reciprocating groove on the surface of the reciprocating screw rod 93 is at the right end of the clip 6, the outer wall of the reciprocating screw rod 93 inside the mounting groove 91 is fixedly connected with a gear 2 94, and the gear 1 92 is meshed with the gear 2 94 A slider 95 is provided on the outside of the reciprocating screw rod 93. The slider 95 can make reciprocating movements in the left and right directions under the drive of the reciprocating screw rod 93. A positioning ring 97 is fixedly connected to the top of the slider 95. A through hole with a diameter larger than the cable diameter is opened in the middle of the front end of the positioning ring 97. A sliding rod 96 is penetrated and slidably connected to the inner wall of the slider 95. The left and right ends of the sliding rod 96 are fixedly connected to one end of the two mounting plates 2 that are close to each other. Through the setting of the sliding rod 96, it is ensured that during the rotation of the reciprocating screw rod 93, the slider 95 cannot rotate with the rotation of the reciprocating screw rod 93 and can only reciprocate in the left and right directions.

[0037] Working principle: When in use, the user takes out the cable end that needs to be tested, passes it through the through hole in the middle of the positioning block 71, the through hole in the middle of the detection plate 72 and the through hole in the middle of the positioning ring 97, and then clamps the end of the cable with the clamp 6. After clamping is completed, the staff starts the motor body 4.

[0038] When the motor body 4 is started, the output shaft of the motor body 4 drives the winding rod 5 to rotate, so that the cable fixed by the clamp 6 can be wound around the outside of the winding rod 5 during the rotation of the winding rod 5. At the same time, the winding rod 5 drives gear 1 92 to rotate, and drives gear 2 94 to rotate through gear 1 92, so that the reciprocating screw rod 93 rotates under the drive of gear 2 94, so that the slider 95 moves back and forth in the left and right directions under the drive of the reciprocating screw rod 93, thereby driving the cable to be wound in the process of moving left and right, ensuring that the cable can be evenly distributed on the outside of the winding rod 5.

[0039] When the cable is moved, due to the height difference between the positioning block 71 and the through hole of the detection plate 72, the area where the cable is located between the positioning block 71 and the detection plate 72 is in a vertical state. Since the hole on the detection plate 72 is horizontal and the line connecting the through hole between the detection plate 72 and the positioning ring 97 is approximately horizontal, when the cable enters the hole inside the detection plate 72, there is a certain degree of bending. Therefore, if it is damaged, the damaged part is likely to produce a greater deformation due to the bending. At this time, after the hole moves to the horizontal position where the moving rod 73 is located, the moving rod 73 moves in the direction of entering the hole under the elastic force of the spring 1 76, so that the moving rod 73 is displaced and drives the control block 77 to move, so that the control block 77 pushes the inclined surface of the pressure block 79 through the inclined surface, so that the pressure block 79 moves backward and drives the moving ring 78 to move backward, thereby contacting the motor switch 8, so that the motor switch 8 is turned off. At this time, if the user finds that the equipment stops running, he can distinguish the damaged part of the cable insulation layer.

[0040] At the same time, if the damaged area appears on the concave surface of the cable bend, the damaged area will still expand, but an outward bulge will appear on the surface of the damaged insulation layer. When the roller 74 rolls to the bulge, since the surface of the roller 74 is a cylindrical surface, the bulge can squeeze the roller 74 at this time, so that the roller 74 drives the moving rod 73 to move toward the side away from the cable first. When it moves away from the bulge and the hole appears, the moving rod 73 and the roller 74 enter the hole again.

[0041] The above contents described in this specification are merely examples of the present utility model. A person skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in a similar manner, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, and they shall all fall within the protection scope of the present utility model.
