Description

Technical Field

[0001] This utility model relates to the field of cable fault location technology, specifically a cable grounding fault location device. Background Technology

[0002] A cable fault locator is a comprehensive cable fault detection instrument that can test for high-resistance flashover faults, high and low-resistance grounding faults, short circuits, cable breaks, poor contacts, and other faults in cables. Equipped with an acoustic fault location device, it can accurately determine the precise location of the fault. It is particularly suitable for testing various types and voltage levels of power cables and communication cables.

[0003] Existing cable fault locators are generally placed in a specially designed device box, and the four sides of the cable fault locator are fixed and limited by a placement pad to prevent the cable fault locator from shaking inside the device box. However, when it is necessary to use the cable fault locator to locate and detect cable faults, there is a problem that it is not convenient and quick to take it out. Therefore, corresponding improvements are needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cable grounding fault location device to solve the problems mentioned in the background art.

[0006] Preferably, the interior of each of the four sets of mounting holes is inserted into the interior of the mounting rod, and the top end of each mounting rod is installed with the bottom end of the cover plate, and a hand handle is installed on the top end of the cover plate.

[0007] Preferably, the top of the placement slot is open, and a through hole is provided inside the placement pad near the electric push rod.

[0008] Preferably, one end of the electric push rod passes through a through hole into the inner wall of the bottom end of the placement pad and extends into the interior of the spiral plate, and the placement plate is located inside the spiral plate.

[0009] Preferably, the slider is located inside the slide groove, and the slider is slidably connected to the inside of the slide groove.

[0010] Preferably, the outer diameter of the four sets of positioning rods is adapted to the inner diameter of the four sets of positioning grooves, and one end of each of the four sets of positioning rods is inserted into the interior of the corresponding positioning groove.

[0011] Preferably, the outer frame of the detector is adapted to the inner frame of the rectangular plate, and the detector is placed inside the rectangular plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating components such as an electric push rod, placement plate, slider, positioning rod, placement pad, U-shaped plate, and slide groove, this design effectively solves the problem that existing cable fault locators are typically placed in a specially designed device box and secured on all four sides using placement pads. This prevents the cable fault locator from shaking inside the box, but when it is needed to locate and detect cable faults, there is a problem that it is not convenient and quick to remove the cable fault locator.

[0014] When a cable fault location tester is needed, the user can move the cover plate upwards using a hand lever. This allows the four sets of mounting rods to move upwards from their respective mounting holes. Then, the user can activate the electric push rod, which moves the placement plate upwards within the U-shaped plate. This causes the two sets of sliders to move upwards within their respective sliding grooves, allowing the tester to move upwards and exit from the U-shaped plate. The tester can then be easily moved upwards, allowing the four positioning rods to move out of their respective positioning slots. Once the tester separates from the placement plate, the cable fault location tester can be performed. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To achieve the above objectives, according to Figures 1-4 As shown, the present invention provides the following technical solution: a cable grounding fault location device, including a device box 1, with mounting holes 11 on all four sides of the top of the device box 1, and a placement groove 12 inside the device box 1. An electric push rod 13 is installed inside the placement groove 12, and a placement plate 14 is installed on the top of the electric push rod 13. Slider blocks 15 are installed on both sides of the placement plate 14, and positioning rods 16 are installed on all four sides of the top of the placement plate 14.

[0022] Inside the device box 1, above the placement groove 12, a placement pad 2 is embedded, and inside the placement pad 2, a U-shaped plate 21 is embedded. Both sides of the inner wall of the U-shaped plate 21 are provided with sliding grooves 22. The top of the placement groove 12 is open. Inside the placement pad 2, near one end of the electric push rod 13, a through hole 23 is provided. One end of the electric push rod 13 passes through the through hole 23, passes through the bottom inner wall of the placement pad 2, and extends into the interior of the U-shaped plate 21. The placement plate 14 is located inside the U-shaped plate 21, and the slider 15 is located inside the sliding groove 22.
