Description

Technical Field

[0001] This utility model relates to the technical field of cable inspection, and in particular to a cable defect location device. Background Technology

[0002] A cable is a device for transmitting electricity. Its interior is a conductive metal core, and the outer surface of the metal core is usually covered with an insulating layer for insulation. During long-term use, cables are prone to internal damage due to natural aging or human-caused damage. Once the internal of the cable is damaged, it can easily cause leakage and short circuits, and in severe cases, it can cause fires. Therefore, it is necessary to inspect cables regularly to locate defects and then repair them to avoid risks caused by internal cable damage.

[0003] However, when detecting and locating internal defects in cables, the operator uses a detection device to locate the defect and then marks it with a marker pen for easy maintenance. However, this is very inconvenient for the operator to use the marker pen, and the marker pen is easy to lose. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cable defect location device that facilitates marking and locating the position of cable defects.

[0005] This utility model provides the following technical solution: a cable defect locating device, including a handle, an annular arc-shaped block at the end of the handle, an opening through one side of the arc-shaped block, and an indicator on the outer wall of the handle. The locating device also includes a magnetic sensor for measuring the magnetic field of the cable and a marking mechanism for marking the cable. The marking mechanism includes several slide rails on the outer wall of the handle, a slider slidably connected to the slide rails, a mounting component on the slider, a marking pen placed on the mounting component, and a fixing component on the mounting component for fixing the marking pen. When the magnetic sensor senses a change in the magnetic field of the cable, it provides a prompt through the indicator.

[0006] Furthermore, the indicator is at least one of the following: an indicator light or a display screen.

[0007] Furthermore, a through hole is formed through the arc-shaped block, and the magnetic sensor is disposed within the through hole.

[0008] Furthermore, a groove is provided on the slide rail, and the slider is slidably connected to the slide rail through the groove. A compression spring is provided between the slider and the slide rail, and the compression spring is located in the groove.

[0009] Furthermore, the push block is fixedly connected to the slider, and the slider can be driven to slide on the slide rail by pushing the push block.

[0010] Furthermore, the fixing component is a bolt, which is threadedly connected to the mounting component. By rotating the bolt, the bolt is pressed against the marking pen to achieve fixation.

[0011] Furthermore, the mounting component is rotatably connected to the slider, a torsion spring is provided between the mounting component and the slider, and the marking mechanism also includes a rotating component for driving the mounting component to rotate.

[0012] Furthermore, the rotating assembly includes a bracket disposed on the slide rail, a rack disposed on the bracket, and a gear disposed on the mounting member. The gear engages with the rack through the guide movement of the slide rail, thereby driving the mounting member to rotate.

[0013] The beneficial effects of this utility model are as follows: by pushing the slider to move closer to the cable, the slider drives the mounting component to move closer to the cable, and the mounting component drives the marking pen on it to move closer to the cable. When the marking pen contacts the cable, it marks the defect location of the cable, thereby achieving the effect of locating the cable defect location and facilitating subsequent repair of the defect location. Thus, by pushing the marking pen to move, it is easy to mark the cable. Furthermore, through the cooperation of gears and racks, the rotation of the mounting component drives the marking pen on it to rotate. Thus, when the marking pen rotates, it will make a relatively large mark on the cable, so that subsequent maintenance personnel can find the defect location by the mark. Attached Figure Description

Detailed Implementation

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] A cable defect location device, such as Figure 1 and Figure 2 As shown, the device includes a handle 1, an annular arc-shaped block 2 at the end of the handle 1, an opening 3 through one side of the arc-shaped block 2, an indicator on the outer wall of the handle 1, a magnetic sensor 7 for measuring the magnetic field of the cable, a through hole 8 through the arc-shaped block 2, the magnetic sensor 7 disposed within the through hole 8, and a marking mechanism 6 for marking the cable. The marking mechanism 6 includes several slide rails 61 on the outer wall of the handle 1, a slider 62 slidably connected to the slide rails 61, a mounting member 63 on the slider 62, a marking pen 67 placed on the mounting member 63, and a fixing member on the mounting member 63 for fixing the marking pen 67. When the magnetic sensor 7 senses a change in the magnetic field of the cable, it provides a prompt through the indicator.

[0023] In this embodiment, two slide rails 61 are fixedly connected to the outer wall of the handle 1. Slider 62s are slidably connected to each slide rail 61. A mounting member 63 is disposed between the two sliders 62. The handle 1 is equipped with a power supply, a control board, and a switch. The power supply, control board, and switch are existing technologies and are not shown in the figure. It can be understood that when it is necessary to detect and locate internal defects in a cable, the operator can insert the energized cable into the inner side of the arc-shaped block 2 through the opening 3, and then operate the switch to energize the control board magnetic sensor 7 and the indicator. The operator then holds the handle 1 and moves the entire positioning device along the extension direction of the cable. When the positioning device moves to the defect location of the cable, the magnetic field at the defect location is relatively large, and the magnetic sensor 7 detects it. The magnetic sensor 7 senses a large magnetic field fluctuation and sends the information to the control board. The control board processes the information and sends it to the indicator. By observing the indicator, the operator can determine the location of the cable fault. When a defect is detected at the cable location, the operator can push the slider 62 towards the cable. The slider 62 moves the mounting part 63 towards the cable, and the mounting part 63 moves the marking pen 67 on it towards the cable. When the marking pen 67 contacts the cable, it marks the location of the cable defect, thus locating the defect and facilitating subsequent repairs. After marking the defect location, the operator resets the marking pen 67 and continues the above operation to test subsequent cables.

[0024] The indicator is at least one of the following: indicator light 4, display screen 5.

[0025] In this embodiment, the indicator includes an indicator light 4 and a display screen 5. When the magnetic sensor 7 senses a change in the magnetic field at the location of a cable defect, the indicator light 4 is turned on by the control board to alert people that a defect has been detected and can be marked. The data on the change in magnetic field is also processed by the control board and displayed on the display screen 5. The operator can also judge whether there is a defect at the location of the cable by looking at the display screen 5.

[0026] like Figure 4 As shown, a groove 69 is provided on the slide rail 61, and the slider 62 is slidably connected to the slide rail 61 through the groove 69. A compression spring 68 is provided between the slider 62 and the slide rail 61, and the compression spring 68 is located in the groove 69.

[0027] It is understandable that when the operator pushes the slider 62 to move closer to the cable, the compression spring 68 is compressed. After the operator marks and locates the defect position of the cable, he only needs to release the slider 62. The compression spring 68 will reset and drive the sliding mechanism to reset, thereby causing the mounting part 63 to drive the marking pen 67 to reset.

[0028] like Figure 3 As shown, the push block 64 is fixedly connected to the slider 62, and the slider 62 is driven to slide on the slide rail 61 by pushing the push block 64.

[0029] It can be understood that the push block 64 set between the two sliders 62 can be pushed to move the sliders 62, which in turn moves the mounting part 63, thereby enabling the marking pen 67 to make marks.

[0030] like Figure 3 As shown, the fixing component is a bolt 65, which is threadedly connected to the mounting component 63. By rotating the bolt 65, the bolt 65 is pressed against the marking pen 67 to achieve fixation.

[0031] It is understandable that when the marker pen 67 is damaged, the operator can rotate the bolt 65 so that the bolt 65 no longer presses the marker pen 67. Then the operator can remove the marker pen 67 from the mounting part 63, replace it with a new marker pen 67, and then rotate the bolt 65 in the opposite direction so that the bolt 65 abuts against the outer wall of the marker pen 67 and presses it, thereby fixing the marker pen 67.

[0032] like Figure 3 As shown, the mounting member 63 is rotatably connected to the slider 62, and a torsion spring 664 is provided between the mounting member 63 and the slider 62. The marking mechanism 6 also includes a rotating component 66 for driving the mounting member 63 to rotate. The rotating component 66 includes a bracket 661 provided on the slide rail 61, a rack 662 provided on the bracket 661, and a gear 663 provided on the mounting member 63. The gear 663 moves under the guidance of the slide rail 61 and meshes with the rack 662, thereby driving the mounting member 63 to rotate.

[0033] It is understandable that when the slider 62 moves closer to the cable, the slider 62 drives the mounting part 63 to move, and the mounting part 63 drives the gear 663 to move. When the gear 663 moves to contact the rack 662, the rack 662 will drive the gear 663 to rotate. The rotation of the gear 663 will drive the mounting part 63 to rotate, and the torsion spring 664 will deform. The rotation of the mounting part 63 will drive the marking pen 67 on it to rotate. Thus, when the marking pen 67 rotates, it will make a relatively large mark on the cable so that subsequent maintenance personnel can find the defect location by the mark. When the slider 62 returns to its original position, the rack 662 will also drive the gear 663 to rotate and reset the mounting part 63. The torsion spring 664 will also reset from the deformed state. Through the action of the torsion spring 664, the mounting part 63 can be kept at an angle so that it does not rotate arbitrarily.

[0034] In summary, by pushing the slider 62 to move closer to the cable, the slider 62 drives the mounting part 63 to move closer to the cable, and the mounting part 63 drives the marking pen 67 on it to move closer to the cable. When the marking pen 67 contacts the cable, it marks the location of the cable defect, thereby achieving the effect of locating the cable defect and facilitating subsequent repair. Thus, by pushing the marking pen 67 to move, it is easy to mark the cable. Furthermore, through the cooperation of the gear 663 and the rack 662, the rotation of the mounting part 63 drives the marking pen 67 on it to rotate. As the marking pen 67 rotates, it will make a relatively large mark on the cable, so that subsequent maintenance personnel can find the defect location by the mark.
