[0002] Power line inspection is a crucial part of ensuring the safe operation of the power system. High-definition images of power equipment (such as transformers, insulators, and conductors) are collected using handheld or fixed devices to monitor equipment status and detect potential faults. However, existing image acquisition equipment has the following problems in power line inspection scenarios: First, ordinary cameras have insufficient resolution, making it difficult to capture subtle defects in the equipment (such as cracks in insulators or wear on conductors). Secondly, the equipment is complex to operate or too large, making it inconvenient for inspection personnel to carry and use in the field or high-altitude working environments (such as power poles and substations); Third, network coverage is insufficient in complex environments (such as remote mountainous areas or underground substations), limiting wireless transmission of image data; fourth, there is a lack of image optimization and efficient transmission technologies for power inspection environments, making it difficult to balance image quality and transmission efficiency. With the rapid growth of my country's power infrastructure and the increase in inspection tasks, there is an urgent need for an efficient, portable image acquisition device that can adapt to complex network environments in order to improve inspection efficiency and data transmission reliability.

[0020] Working principle: During power inspection, push the frame 1 and move the device to the target inspection area via the casters 2 at the bottom. Activate the locking device on the casters 2 to fix the device position and prevent the device from moving during the inspection. The frame 1 and the cover plate 3 are fixedly connected through the mounting holes 4 to form a stable load-bearing structure. The bottom of the X-shaped connecting plate 7 passes through the connecting holes 5 on the cover plate 3.

The Mesh network can transmit data stably in complex environments, with a single-hop latency of less than 50ms. On the guide rail 8 at the bottom of the cover plate 3, the sliding plate 9 can drive the U-shaped cable clamp 10 to slide linearly along the guide rail 8. The cable clamp 10 organizes and fixes the cables in the device, such as the data cable and power cable of the camera 15, to prevent the cables from getting tangled and messy. The acquired images are transmitted to the backend system via Mesh self-organizing network technology, completing the process of acquiring and transmitting power inspection images; The casters 2 at the bottom of frame 1 allow the device to move flexibly within the inspection area, adapting to the power inspection needs of different terrains. The locking device can quickly fix the device position, ensuring that the device does not shake during image acquisition and improving shooting stability. Four fixed plates 6 are arranged in an array to restrict the horizontal displacement of the X-shaped connecting plates 7 from all sides. Combined with the connection holes 5, the camera 15 and related components are firmly installed, reducing the impact of vibration and collision on the acquisition equipment during the inspection process and ensuring the stability of image acquisition.
