Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a camera mount assembly for power line maintenance UAVs. Background Technology

[0002] Drones are frequently used in the maintenance of power lines, such as in mountainous and forested areas where transportation is difficult. In such cases, manual inspection is dangerous and difficult, while drones can effectively observe and inspect power lines at high altitudes.

[0003] Currently available drones are divided into two types: those with cameras and those without. In order to ensure the clarity of drone footage during power line inspections, it is generally necessary to install additional cameras so that the condition of the lines can be clearly captured and transmitted to the monitoring room for easy inspection and observation.

[0004] Patent document CN209938984U discloses a camera fixing device for drone aerial photography. Addressing the problem of poor fixing effect in existing drone camera fastening connections, the following solution is proposed: It includes a drone housing, a buffer pad on the lower surface of the drone housing, a motor installed in the middle of the lower surface of the buffer pad, and a rotating plate connected to the motor's output shaft. Guide rods are symmetrically fixed on both sides of the lower surface of the drone housing, with a first positioning block fixed on each guide rod. A second positioning block is movably fitted at the bottom of the guide rod, and a buffer spring is provided between the first and second positioning blocks. Grooves are provided on the adjacent sidewalls of the two second positioning blocks, and a mounting plate is provided between the two second positioning blocks. This utility model has a simple structure and novel design, can easily fix the camera, reduce the vibration experienced by the camera, ensure shooting effect, and extend the camera's service life, making it worthy of promotion.

[0005] As in the prior art of the aforementioned patent, existing drones are equipped with landing gear. The aforementioned fixing device directly installs guide rods and mounting rods under the drone's shell without avoiding the landing gear. This is because the spacing and length of the landing gear vary depending on the size of the drone, and the camera mounting mechanism cannot be adapted to landing gears of all sizes. Furthermore, the guide rods and mounting rods of the aforementioned device are fixedly installed under the drone's shell and cannot be disassembled. This makes subsequent maintenance and upkeep quite troublesome for both the drone and the mounting mechanism. Utility Model Content
