Description

Technical Field

[0001] This utility model relates to the field of inspection drone technology, specifically a modular quick-assembly inspection drone. Background Technology

[0002] Inspection drones are widely used in fields such as power, oil and gas, and security, enabling multi-dimensional inspection of target areas by carrying different detection components. However, existing inspection drones still have the following problems in use: the detection components of traditional inspection drones (such as optical cameras and thermal imagers) are mostly integrated and fixed. When it is necessary to replace different types of detection equipment or perform component maintenance, the disassembly and assembly process is cumbersome, often requiring special tools and taking a long time, which seriously affects the efficiency of inspection operations. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a modular quick-assembly inspection drone. By setting up a quick-assembly structure with a top-mounted inspection component, a modular assembly component, and a bottom-mounted inspection component, it solves the problems of cumbersome disassembly and assembly and poor connection stability of existing inspection drones' detection components.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular quick-assembly inspection drone, comprising an aircraft assembly, wherein the aircraft assembly is configured with a top-mounted inspection assembly, a modular assembly assembly, and a bottom-mounted inspection assembly.

[0007] The aircraft assembly includes a drone main body, which houses a drone main controller for processing detection data, controlling flight, and coordinating with other components. Connecting arms are evenly distributed around the periphery of the drone main body, with rotor components mounted at the ends of these arms furthest from the main body, providing flight propulsion. The top of the drone main body has a first and a second slot for engaging with a top-mounted inspection component. Fixing frames are fixedly connected to both sides of the bottom of the drone main body, with shaft holes on the front and rear sides to support the rotational connection of modular assembly components. Four threaded holes are arranged in a rectangular array at the center of the bottom of the drone main body for fastening with threaded connecting posts of the modular assembly components. The drone main body is also equipped with a drone support frame for support and protection during takeoff and landing.

[0008] The top-mounted inspection component includes a first detector. The bottom of the first detector is provided with a locking block that matches the first slot and a buckle that matches the second slot. The top-mounted inspection component can be quickly installed by the locking of the locking block and the buckle. High-definition optical cameras are installed at the front and rear ends of the first detector to collect high-definition visible light images of the inspection area.

[0009] The modular assembly component includes an upper limit plate, with threaded connecting posts that rotatably connect to the four corners of the top of the upper limit plate and are adapted to threaded holes. By tightening the threaded connecting posts, the modular assembly component can be quickly fastened to the main body of the UAV. The modular assembly component also has a rotating block that rotatably engages with the shaft hole of the fixing frame. The front and rear ends of the rotating block are fixedly connected with connecting bolts that rotatably engage with the shaft hole, further improving the stability of the connection between the modular assembly component and the main body of the UAV. The rotating block is fixedly connected to a bracket for supporting the bottom-mounted inspection component.

[0010] The bottom-mounted inspection component includes a second detector. The second detector is limited and secured above by an upper limit plate and below by two brackets, achieving stable clamping in both directions. An infrared thermal imager is installed on the front side of the bottom of the second detector to detect abnormal temperatures of the inspection target. An ultraviolet imager and a gas sensor are installed on the rear side of the bottom of the second detector. The ultraviolet imager is used to identify ultraviolet signals such as corona discharge, and the gas sensor is used to detect the composition and concentration of ambient gases.

[0011] As a further improvement of this utility model: the rotor assembly is provided in four parts, which are distributed in a cross-shaped symmetrical pattern around the main body of the drone, making the drone flight more stable and the power output more balanced.

[0012] As a further improvement of this utility model: the buckle is provided in two parts, both of which are U-shaped. The two buckles are respectively engaged with the corresponding second slot. The U-shaped structure improves the stability and guidance of the engagement, and facilitates quick alignment and installation.

[0013] As a further improvement of this utility model, four threaded connecting posts are provided, and each is threadedly connected to one of the four threaded holes at the bottom of the UAV main body. Through the synergistic effect of the four threaded connecting posts, the robustness of the connection between the modular assembly components and the UAV main body is ensured.

[0014] As a further improvement of this utility model, an anti-loosening washer is provided at the joint between the nut of the connecting bolt and the outer wall of the corresponding side of the fixing frame to prevent the connecting bolt from loosening due to vibration during the flight of the drone, thereby improving the connection stability.

[0015] As a further improvement of this utility model: the inner side wall of the bracket and the bottom wall of the upper limit plate are both provided with anti-slip textures to increase the friction with the bottom-mounted inspection component and prevent the bottom-mounted inspection component from sliding and shifting.

[0016] As a further improvement of this utility model: the drone support frame has two connecting arms, each with its top end fixedly connected to its corresponding side, and the outside of the drone support frame is fitted with a shock-absorbing rubber sleeve, which plays a buffering and shock-absorbing role when the drone takes off and lands, protecting the fuselage and components.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by adapting and engaging the top-mounted inspection component's locking block and buckle with the first and second locking slots of the UAV main body, and through the coordinated cooperation of the threaded connecting column and threaded hole, rotating block and shaft hole, connecting bolt and fixing frame of the modular assembly component, the top-mounted inspection component and the bottom-mounted inspection component can be quickly modularly disassembled and assembled. Component replacement or maintenance can be completed without special tools, which greatly improves the efficiency of inspection operations.

[0019] 2. In this utility model, the top-mounted inspection component achieves a stable connection through the interference fit of the card block and the card slot. The modular assembly component ensures the connection stability with the main body of the UAV through multiple structures such as threaded connection, shaft hole rotation fit and anti-loosening gasket. The bottom-mounted inspection component further prevents displacement through the bidirectional clamping of the upper positioning plate and bracket and the anti-slip texture. The stability of the connection between each component and the main body of the UAV is improved in multiple dimensions, effectively avoiding the problem of inaccurate detection data caused by component loosening during flight.
