Description

Technical Field

[0001] This invention relates to the field of methane leak detection technology, specifically to an unmanned aerial vehicle (UAV)-borne laser methane leak inspection instrument. Background Technology

[0002] A drone, officially termed an "unmanned aerial vehicle," is a type of unmanned aircraft controlled by radio remote control equipment and its own programmed control system. A complete drone system includes not only the aircraft itself but also the ground control system and communication links.

[0003] A search revealed a Chinese patent with application number "CN202020680495.8", which specifically describes a UAV-borne laser methane leak detector. The device includes a laser detector housing, inside which are a detector and a laser. A lens is located at the front end of the laser detector housing, and the detection laser emitted by the laser is output through the center of the lens. An alignment camera is located above the lens at the front end of the laser detector housing. A three-axis stabilization gimbal is located at the rear end of the laser detector housing. The three-axis stabilization gimbal includes a bracket, a connecting ring, and an angle adjustment frame. The rear end of the laser detector housing is connected to the UAV via the bracket and connecting ring. The UAV is controlled via a ground control terminal to navigate the inspection route.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] During operation, the operator first controls the electric push rod 6318 to raise the lifting plate 6317. The lifting plate 6317 then rotates the inclined plate 6315, which in turn moves the control rod 6313. The control rod 6313 then moves the push block 6312. Under the action of the moving plate 637, the gear plate 638, and the gear 635, the gear 635 drives the rotating rod 634 to rotate. The rotating rod 634 then rotates the protective plate 633 on the L-shaped block 632, protecting the lens with the protective plates 633 on both sides. Simultaneously, the lifting plate 6317 moves the lifting rod 6312. As the lens rises, the control shaft 6322 on the control block 6323 rotates under the action of the lifting block 6328, toothed plate 6329, gear 6327, control plate 6325, and inclined plate 6326. The control shaft 6322 drives the support plate 6320 to rotate, which facilitates the support plate 6320 to support the inspection instrument. At the same time, the lifting plate 6317 drives the push plate 6332 to rise. Under the action of the connecting rod 6333, piston disc 6334, and connecting hose 6331, the arc-shaped airbag 6330 expands to seal the protective plate 633 and prevent external rainwater from entering the lens.
