This invention discloses a coaxial dual-cavity optical detection system, relating to the field of gas detection, which solves the problems of poor portability and low laser utilization in existing equipment. The system includes an air inlet, two coaxially arranged cavities with the inner cavity located inside the outer cavity, a vent, an outlet, a plano-concave mirror, and symmetrical window mirrors. The two cavities are interconnected through the vent, allowing for gas filling and exhaust with a single gas path. Coaxial parallel plano-concave mirrors are installed within the cavities, working in conjunction with an external reflector, convex lens, and detector to guide refracted light incident on the inner cavity into the outer cavity for utilization, forming a closed loop in the optical path of the two cavities. This system significantly reduces longitudinal and lateral dimensions, improving portability; simultaneous dual-cavity detection improves detection accuracy; the utilization of refracted light enhances laser utilization and sensing efficiency; and the increased effective optical path within a limited volume improves gas detection sensitivity, making it suitable for trace gas detection.

This utility model discloses an electric vertical takeoff and landing manned aircraft, including an aluminum alloy frame, a vibration damping assembly, a right guardrail connected to one side of the aluminum alloy frame, and a left guardrail connected to the other side via a pivot seat. The vibration damping assembly includes a first carbon fiber tube and a vibration damping seat fitted on the first carbon fiber tube. The upper and lower vibration damping seats are fastened with bolts through the penetration between the first carbon fiber tube and the aluminum alloy frame. The rubber vibration damping pad absorbs high-frequency vibration energy through its own elastic deformation, effectively blocking the direct transmission of vibration to the frame. The axial anti-roll bracket forms an elastic clamp on the sleeve through rubber clips. This clamping force can be flexibly adjusted by the hardness of the rubber clips, which greatly reduces the vibration felt in the cockpit area. Both the first and second carbon fiber tubes are made of carbon fiber composite material, which has a weak ability to reflect sound waves and can reduce the transmission efficiency of propeller aerodynamic noise.

The application relates to a cleaning base station and a cleaning system, which are used in cooperation with a cleaning robot, wherein the cleaning robot comprises a cleaning piece and a robot main body for driving the cleaning piece to rotate; the cleaning base station comprises a base, a limiting structure and a cleaning tank, the limiting structure and the cleaning tank are arranged on the base, the robot main body can be fixed on the base in an inclined or vertical mode through the limiting structure, meanwhile, the cleaning piece is also at least partially inserted into the cleaning tank to interact with cleaning liquid, the cleaning piece rotates, and the cleaning liquid is uniformly attached to the cleaning piece, so that the cleaning piece is cleaned; through cooperation of the base, the limiting structure and the cleaning tank, the cleaning robot can be fixed on the cleaning base station in an inclined or vertical mode for cleaning, and the transverse size of the base can be greatly reduced, so that the volume of the cleaning base station is reduced, and the packaging and carrying of the cleaning base station are facilitated.

This application relates to the field of tracked walking mechanism technology and discloses a walking mechanism for a multi-functional robot, mainly composed of a driven wheel assembly. The driven wheel assembly is movably arranged at the left end of the chassis. The driven wheel assembly consists of a driven wheel, a guide plate, a support column, and a support plate. The middle part of the guide plate is movably sleeved with the driven wheel, and a tensioning device is fixedly arranged at the right end of the guide plate. In this invention, the tensioning device elongates by pumping in grease, and simultaneously shortens by the slow overflow of grease. When the tensioning device shortens, the tension of the track assembly decreases, allowing the driven wheel and guide plate to slide left and right on the support column. This effectively facilitates the removal and detachment of the track assembly from the drive assembly, enabling rapid replacement of components in the multi-functional robot's walking mechanism. Compared to the traditional operation of removing the articulated track plates of the track assembly, this effectively reduces maintenance time and labor intensity.

The utility model relates to a fire fighting shouting investigation lighting unmanned plane, aims at solving the current fire fighting unmanned plane generally adopts fixed wing or non collapsible structure design, leads to its lateral size is bigger, is difficult to pass through door and window, corridor narrow entrance, thereby fixed wing unmanned plane enters the building inside, needs manual disassembly wing after reassembly, serious delay investigation opportunity technical problem, including: fuselage, the four machine arms with the spiral propeller that the outer periphery side of fuselage evenly distributed have, the top between four machine arms is connected with the apron through detachable component, the utility model drives the eccentric arc -shaped groove through fixed column to push and pull machine arm when driving assembly drives the disc rotation, realizes machine arm along the guide slide rail assembly telescoping, thereby enters narrow lane, door and window before, machine arm shortens and can reduce lateral size, easily passes through narrow channel, compared with the fixed wing unmanned plane, avoids delaying investigation opportunity by omitting the step of disassembly wing.
