Description

Technical Field

[0001] This utility model relates to the field of high-voltage cable detection technology, specifically a high-voltage cable fault detection device. Background Technology

[0002] High-voltage cables are the core carriers of electrical energy transmission in power systems, widely used in urban power grids, industrial parks, and long-distance transmission projects. However, due to factors such as insulation aging, external damage, construction defects, and environmental corrosion, high-voltage cable faults occur frequently, causing minor power outages or even grid paralysis, resulting in significant economic losses and social impact. Currently, high-voltage cable fault detection mainly relies on manual inspections and fault detection devices.

[0003] However, manual inspections are time-consuming and labor-intensive, making it difficult to achieve large-scale, high-frequency testing. Furthermore, they rely on human experience and judgment, which can easily lead to missed hidden faults. Existing fault detection devices for high-voltage cables have limited detection dimensions and cannot accurately locate the damaged parts during testing, making subsequent maintenance work more difficult for staff. Utility Model Content

[0004] This invention proposes a high-voltage cable fault detection device that can automatically inspect, accurately locate fault points, and achieve full-dimensional fault detection of high-voltage cables.

[0005] A high-voltage cable fault detection device includes a housing, an installation frame inside the housing, and a detection module, a walking module, a control module, and a power supply module mounted on the installation frame. The detection module includes two arc-shaped detection plates fixed on the mounting frame. The arc-shaped detection plates are equipped with an infrared thermal imager for collecting cable temperature, a camera for collecting cable appearance image data, and a partial discharge sensor for collecting partial discharge data of the cable. The walking module includes a drive motor, an active walking wheel, an upper driven limit wheel, and a lower driven tension wheel assembly. The active walking wheel and the upper driven limit wheel are located at the top of the mounting frame, and the lower driven tension wheel assembly is located at the bottom of the mounting frame. The drive motor is driven and connected to the active walking wheel, and the active walking wheel is equipped with an encoder for collecting walking data. The detection module and the walking module are both electrically connected to the control module, and the detection module, the walking module, and the control module are all electrically connected to the power supply module.

[0006] With the above structure, the detection module enables the acquisition of temperature, partial discharge, and appearance image data of the high-voltage cable, thus achieving full-dimensional fault detection of the high-voltage cable. The walking module allows the high-voltage cable fault detection device to walk along the high-voltage cable without manual operation, achieving automatic detection of the high-voltage cable. The encoder provides real-time feedback of the motion parameters of the active walking wheel, which, combined with the control module, enables the location of the fault.

[0007] To better collect temperature, partial discharge, and appearance image data of the high-voltage cable, two arc-shaped detection plates are arranged opposite each other. Multiple partial discharge sensors are arranged around the middle of the inner wall of each arc-shaped detection plate. The camera and infrared thermal imager are both located at the end of the arc-shaped detection plate near the upper driven limit wheel.

[0008] Preferably, the drive motor is fixedly mounted on the top of the mounting frame, and a traveling wheel mounting shaft and a limit wheel mounting shaft are rotatably mounted on the top of the mounting frame. A second bevel gear is fixedly mounted on the traveling wheel mounting shaft, and a first bevel gear is fixedly connected to the output end of the drive motor. The first bevel gear and the second bevel gear are connected in a transmission connection. The active traveling wheel and the encoder are both fixedly mounted on the traveling wheel mounting shaft, and the upper driven limit wheel is rotatably mounted on the limit wheel mounting shaft.

[0009] To enable the high-voltage cable fault detection device to move more effectively along the high-voltage cable, a drive cylinder is provided on the top of the mounting frame. A first hinge rod is hinged to the output end of the drive cylinder. A turntable is fixedly mounted on the end of the traveling wheel mounting shaft away from the drive motor. The side of the turntable is hinged to the first hinge rod.

[0010] To ensure a tight fit with the surface of the high-voltage cable, the lower driven tensioning wheel assembly includes two tensioning wheel mounting shafts. A lower driven tensioning wheel is rotatably mounted on the tensioning wheel mounting shafts. The two tensioning wheel mounting shafts are connected by a tensioning mechanism. Both ends of the tensioning wheel mounting shafts are hinged with a second hinge rod. The end of the second hinge rod away from the tensioning wheel mounting shaft is hinged to the bottom of the mounting frame.

[0011] Preferably, the tensioning mechanism includes a connecting frame fixedly mounted on the tensioning wheel mounting shaft, and the two connecting frames are connected by a tension spring.

[0012] To prevent the high-voltage cable fault detection device from damaging the outer surface of the high-voltage cable during its movement, the active walking wheel, the upper driven limit wheel, and the lower driven tensioning wheel are all equipped with a wear-resistant rubber layer.

[0013] Preferably, the control module includes a control chip, a storage module, a wireless communication module, and a positioning module; the wireless communication module is a 4G / 5G dual-mode communication module, and the positioning module is a GPS / BeiDou dual-mode positioning chip.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are: The high-voltage cable fault detection device provided by this utility model is equipped with a detection module, which integrates multiple sensors, including a partial discharge sensor, a camera, and an infrared thermal imager. This module can collect temperature, partial discharge, and appearance image data of the high-voltage cable, achieving full-dimensional fault detection. The walking module allows the device to move along the high-voltage cable without manual operation, enabling automatic detection. The encoder provides real-time feedback of the motion parameters of the active walking wheel, which, combined with the control module, allows for the location of the fault. The drive cylinder and lower driven tensioning wheel assembly ensure that the device moves more effectively along the high-voltage cable, guaranteeing that both the active walking wheel and the lower driven tensioning wheel are in close contact with the surface of the high-voltage cable.

The active traveling wheel 31 and the encoder 35 are both fixedly mounted on the traveling wheel mounting shaft. The upper driven limit wheel 4 is rotatably mounted on the limit wheel mounting shaft. The drive motor 32 rotates, driving the first bevel gear 33 to rotate, which in turn drives the second bevel gear 34 to rotate, which in turn drives the traveling wheel mounting shaft to rotate. This allows the high-voltage cable fault detection device to travel along the high-voltage cable without manual hand operation, thus realizing automatic detection of the high-voltage cable.

[0023] The top of the mounting frame 11 is equipped with a drive cylinder 36, which is an electric cylinder. The output end of the drive cylinder 36 is hinged to a first hinge rod 37.
