Description

Technical Field

[0001] This utility model relates to the field of overhead contact line inspection technology, specifically to an overhead contact line suspension inspection device. Background Technology

[0002] As a core component of the rail transit power supply system, the overhead contact system's suspension structure includes key components such as suspension columns, flexible cables, and droppers. The operational status of the suspension structure directly determines the stability of power supply and the safety of vehicle operation. With the continuous increase in the operating mileage and speed of rail transit, the inspection of the overhead contact system's suspension structure is becoming increasingly important, and the requirements for the efficiency and accuracy of inspections are also becoming higher.

[0003] Current methods for inspecting overhead contact lines mainly rely on manual inspection and inspection using traditional testing equipment. Manual inspection requires workers to use elevated equipment or inspection vehicles for observation, which has problems such as low efficiency, high labor intensity, and strong subjectivity. Traditional testing equipment mostly uses a single imaging module to photograph the entire overhead contact line, making it difficult to accurately inspect the structural characteristics of different components such as suspension columns, flexible cables, and droppers.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The technical solution of this utility model will be further illustrated below through specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The content of the embodiments does not constitute a limitation on this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1-2 As shown, this utility model discloses a catenary suspension inspection device, which is used to inspect and test the catenary, promptly detect defects in the catenary, and carry out timely maintenance to ensure the normal use of the catenary.

[0021] In this application, the overhead contact line suspension inspection device is installed on the top of the inspection vehicle, which has an inspection platform on top. The overhead contact line suspension inspection device includes a suspension column inspection module, a flexible cable inspection module, a dropper wire inspection module, and a data processing module.

[0022] The suspended column inspection module is used to identify and photograph the suspended columns of the overhead contact system; the flexible cable inspection module is used to identify and photograph the cables of the overhead contact system; and the dropper inspection module is used to identify and photograph the droppers of the overhead contact system.

[0023] The suspended column inspection module includes a suspended column imaging unit, a suspended column identification triggering unit, and a suspended column lighting compensation unit, which are connected in sequence. The suspended column imaging unit uses a high-definition industrial camera, capable of resolving detailed information about the suspended column and promptly detecting defects.

[0024] Preferably, four suspended column imaging units are provided, arranged in a rectangle on the inspection platform, with the imaging lens facing upwards from the center of the rectangle. This ensures omnidirectional imaging of the suspended column and avoids blind spots.

[0025] The suspended column lighting compensation unit is an LED fill light, which has advantages such as low energy consumption and fast response speed. There are four suspended column lighting compensation units, which are positioned in the center of the rectangular structure formed by the four suspended column imaging units to ensure that the fill light can evenly cover the surrounding suspended columns.

[0026] The suspended pillar imaging unit includes an infrared sensor and an image recognition camera. When the inspection vehicle drives near the suspended pillar, the infrared sensor first senses the outline of the suspended pillar, triggering the image recognition camera to make a preliminary image judgment. Once it is confirmed to be a suspended pillar, the suspended pillar imaging unit is immediately triggered to start shooting, so as to ensure the accuracy of the shooting timing and avoid collecting invalid images.

[0027] Preferably, the flexible cable inspection module includes a flexible cable positioning and imaging unit, a flexible cable identification triggering unit, and a flexible cable lighting compensation unit, which are electrically connected in sequence. The flexible cable positioning and imaging unit includes a high-definition camera with variable zoom, enabling precise and high-definition imaging of the cable. The flexible cable identification triggering unit includes a laser sensor, which scans the contact wire area by emitting a laser beam. When the contour features of the flexible cable are detected, the flexible cable positioning and imaging unit is immediately triggered to locate and capture images.

[0028] Specifically, there are four flexible cable positioning imaging units, which are distributed on the top of the inspection vehicle to ensure all-round imaging of the cable and avoid blind spots.

[0029] Four flexible cable lighting compensation units are provided, and these four units are distributed on the top of the inspection vehicle. By distributing the flexible cable lighting compensation units, it is ensured that the supplementary lighting can evenly cover the contact wire cables around the perimeter.

[0030] The flexible cable lighting compensation unit includes a xenon fill light, which features high light intensity and wide coverage, meeting the shooting needs of flexible cables in complex lighting environments such as strong light and backlight.

[0031] The dropper inspection module is used to identify and photograph the droppers of the overhead contact system. The droppers are key components that connect cables and catenary wires. If the droppers are broken, corroded, or displaced, it will directly affect the stability of the overhead contact system.

[0032] The dropper inspection module comprises a dropper imaging unit, a dropper recognition trigger unit, and a dropper lighting compensation unit, all electrically connected in sequence. The dropper imaging unit includes a macro high-definition camera, capable of capturing close-up details of the dropper and promptly identifying defects such as rust spots and loose connections. The dropper recognition trigger unit includes a laser sensor, which scans the area where the dropper might be present by emitting a laser beam. When the outline of the dropper is detected, the dropper imaging unit is immediately triggered to take an image. The dropper lighting compensation unit is a xenon supplemental lamp, which features high light intensity and wide coverage, meeting the shooting needs of droppers in complex lighting environments such as strong light and backlight.

[0033] Specifically, there are two suspension imaging units, which are installed on the top of the inspection vehicle at different shooting angles. There are also four suspension lighting compensation units, which are distributed across the top of the inspection vehicle. By using these multi-angle suspension lighting compensation units for supplementary lighting, shadows on the suspension can be eliminated, improving image contrast and clarity.

[0034] The data processing module is electrically connected to the suspended column imaging unit, the flexible cable positioning imaging unit, and the drop wire imaging unit, respectively. The data processing module processes and analyzes the images acquired by these units, performing identification and analysis to determine the presence of defects. The data processing module then outputs the analysis results.

[0035] Preferably, the overhead contact line suspension inspection device also includes a storage module, which is connected to the data processing module. The storage module is used to store images and the analysis results of the data processing module.

[0036] The data processing module can retrieve data stored in the storage module at any time and can perform data retrieval based on time.
