Description

Technical Field

[0001] This utility model belongs to the field of railway catenary inspection technology, specifically relating to an online inspection device for railway catenary insulators based on AI vision. Background Technology

[0002] Railway contact wire insulators are core components that ensure the safe operation of electrified railways. Their function is to isolate high-voltage live conductors from the grounding structure, prevent current leakage, and support the contact wires.

[0003] Most existing AI vision-based online inspection devices for railway contact network insulators lack the ability to adjust the angle of the inspection device. This prevents the insulators from being inspected from different angles, reducing the effectiveness of the inspection and thus presenting a defect.

[0004] To address the aforementioned issues, this application proposes an online inspection device for railway catenary insulators based on AI vision. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an online inspection device for railway contact wire insulators based on AI vision, which features adjustable angle of the inspection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online inspection device for railway contact network insulators based on AI vision, including a suspension frame, and further comprising: An insulator body is provided at the bottom of the suspension, an adjustment mechanism is provided at the top of the suspension, and a detection mechanism is provided on the right side of the suspension surface; The testing institutions include: A support frame is provided on the right side of the bottom of the suspension. A first positioning plate is fixedly connected to the left side of the bottom of the support frame. A first support shaft is rotatably connected inside the first positioning plate. A first positioning component is rotatably connected to the surface of the first support shaft. A cylinder is fixedly connected to the bottom of the first positioning component. A fixed shaft is rotatably connected to the bottom of the cylinder. A positioning frame is rotatably connected to the surface of the fixed shaft.

[0007] Preferably, a vertical plate is fixedly connected to the right side of the positioning frame, a second positioning component is fixedly connected to the top of the vertical plate, a second support shaft is rotatably connected inside the second positioning component, a second positioning plate is rotatably connected to the surface of the second support shaft, and the second positioning plate is fixedly connected to the bottom right side of the support frame. The second positioning component and the second support shaft serve as fulcrums to share part of the load when driven by the cylinder, making the lifting and lowering movement of the positioning frame more stable and reducing stress concentration in the support frame.

[0008] Preferably, the main body of the detection device is fixedly connected to the left side of the vertical plate. The main body of the detection device is located on the right side of the insulator body. The main body of the detection device is installed on the right side of the insulator body, forming a specific angle with the insulator body, which can realize multi-view imaging and cover defects such as dirt, cracks, and damage on the surface of the insulator.

[0009] Preferably, a mounting plate is fixedly connected to the top of the support frame, and a fixing rod is inserted into the mounting plate. The fixing rod is located on the right side of the suspension surface. The insertion and connection between the mounting plate and the fixing rod enables the rapid assembly of the testing mechanism, allowing maintenance or replacement to be completed without complicated tools, thereby improving on-site operation efficiency.

[0010] Preferably, one end of the fixing rod is threaded, and a locking nut is threadedly connected to one end of the fixing rod. The locking nut and the thread of the fixing rod cooperate to provide preload force, preventing the testing mechanism from loosening due to vibration of train operation during the testing process, and ensuring long-term stable operation of the equipment.

[0011] Preferably, the adjustment mechanism includes support members, each of which is fixedly connected to both sides of the bottom of the suspension. A threaded rod is rotatably connected between two of the support members. A motor is fixedly connected to the left side of the surface of the threaded rod, and the motor is fixedly connected to the left side of the bottom of the suspension. A sliding plate is threadedly connected to the surface of the threaded rod, and the insulator body is fixedly connected to the bottom of the sliding plate. The sliding plate is connected to the suspension through the support members on both sides, so that the weight of the insulator body is evenly distributed, reducing the deformation and stress concentration of the suspension.

[0012] Preferably, the bottom of the suspension is provided with a sliding groove, and a limiting plate is slidably connected in the sliding groove. The limiting plate is fixedly connected to the top of the sliding plate. The sliding groove limits the movement trajectory of the sliding plate to prevent it from deviating or twisting when the threaded rod rotates, thus ensuring the movement accuracy of the insulator body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This AI vision-based online inspection device for railway contact network insulators can detect minute cracks and hidden dirt accumulation on the surface of the insulator body from different angles, thus improving the inspection effect of the insulator body.

[0014] 2. This AI vision-based online inspection device for railway contact network insulators can quickly isolate fault points and reduce power outage time by moving its sliding plate along a horizontal position when the insulator body itself is damaged or aged, or when there are safety hazards such as trees or foreign objects in the surrounding area. At the same time, it can avoid the impact of the external environment on the insulation performance of the insulator body.

[0015] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0020] Furthermore, a vertical plate 202 is fixedly connected to the right side of the positioning frame 201, and a second positioning member 28 is fixedly connected to the top of the vertical plate 202. A second support shaft 27 is rotatably connected inside the second positioning member 28, and a second positioning plate 26 is rotatably connected to the surface of the second support shaft 27. The second positioning plate 26 is fixedly connected to the bottom right side of the support frame 25. The second positioning member 28 and the second support shaft 27 serve as fulcrums to share part of the load when the cylinder 21 is driven, making the lifting and lowering movement of the positioning frame 201 more stable and reducing stress concentration in the support frame 25.

[0021] Furthermore, a detection device body 203 is fixedly connected to the left side of the vertical plate 202. The detection device body 203 is located on the right side of the insulator body 4. The detection device body 203 is installed on the right side of the insulator and forms a specific angle with the insulator body 4, which can realize multi-view imaging and cover defects such as dirt, cracks, and damage on the surface of the insulator.

[0022] Furthermore, a mounting plate 204 is fixedly connected to the top of the support frame 25, and a fixing rod 205 is inserted into the mounting plate 204. The fixing rod 205 is located on the right side of the surface of the suspension 1. The insertion and cooperation between the mounting plate 204 and the fixing rod 205 can realize the rapid assembly of the detection mechanism 2, and maintenance or replacement can be completed without complicated tools, thereby improving on-site operation efficiency.

[0023] Furthermore, one end of the fixing rod 205 is threaded, and a locking nut is threadedly connected to the other end of the fixing rod 205. The locking nut and the thread of the fixing rod 205 cooperate to provide preload force, preventing the detection mechanism 2 from loosening due to vibration of train operation during the detection process, and ensuring long-term stable operation of the equipment.

[0024] Example 2: See Figure 4 Furthermore, based on Embodiment 1, the adjustment mechanism 3 includes support members 32, which are fixedly connected to both sides of the bottom of the suspension 1. A threaded rod 35 is rotatably connected between the two support members 32. A motor 31 is fixedly connected to the left side of the surface of the threaded rod 35.

The groove limits the movement trajectory of the sliding plate 34 to prevent it from shifting or twisting when the threaded rod 35 rotates, thus ensuring the movement accuracy of the insulator body 4.

[0026] The working principle and usage process of this utility model are as follows: When it is necessary to detect the fine cracks and hidden dirt on the surface of the insulator body 4, the cylinder 21 can be started. When the cylinder 21 performs stretching or compression, the vertical plate 202 can be swung, thereby adjusting the angle of the detection device body 203. This allows for the detection of fine cracks and hidden dirt on the surface of the insulator body 4 from different angles, improving the detection effect of the insulator body 4. When the position of the insulator body 4 needs to be adjusted, the motor 31 can be started. The motor 31 can drive the threaded rod 35 to rotate. During the rotation of the threaded rod 35, the sliding plate 34 can be moved horizontally. When the insulator body 4 is damaged or aged, or there are safety hazards such as trees or foreign objects in the vicinity, moving the insulator body 4 can quickly isolate the fault point, reduce the power outage time, and avoid the influence of the external environment on the insulation performance of the insulator body 4.
