[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 4 As shown, this embodiment provides a natural gas inspection drone, including: a drone body 1, a camera structure, and several propeller structures. The camera structure is detachably connected to the drone body 1 via a connecting shaft 2. The camera structure includes an angle adjustment structure and a camera 5. The camera 5 is used to acquire images. The angle adjustment structure can adjust the angle of the camera 5. A gas monitoring sensor 17 is provided on the camera 5. The gas monitoring sensor 17 is preferably located on one side or outside the lens of the camera 5. The gas monitoring sensor 17 is used to monitor whether there is a gas leak. The gas monitoring sensor 17 is preferably a methane sensor. Several propeller structures are all provided on the drone body 1 and are evenly arranged along the circumference of the drone body 1. This embodiment provides a natural gas inspection drone, which is applied to the scenario of monitoring and inspecting natural gas pipelines. In this embodiment, the drone body 1 and the camera structure are detachable, and upgrades, improvements, and reassemblies can be achieved by replacing the drone body 1 or the camera structure. In this embodiment, the angle of the camera 5 can be changed by the angle adjustment structure, thereby increasing the monitoring range.

[0022] In some specific embodiments, the main body 1 of the drone is provided with a heat dissipation vent, and a fan blade 21 is provided at the heat dissipation vent.

[0023] In some specific embodiments, the drone body 1 is provided with a display screen 6, which is used to display the working status of the drone body 1, such as the drone's attitude, so that the staff can observe it more conveniently.

[0024] In some specific embodiments, the propeller structure includes a connecting block 7, a connecting rod 8, a sleeve 9, and a propeller blade 10. The connecting block 7 is disposed on the outer peripheral surface of the drone body 1 and is fixed relative to the drone body 1. One end of the connecting rod 8 is connected to the connecting block 7, and the other end of the connecting rod 8 is connected to the sleeve 9. The propeller blade 10 is disposed on the sleeve 9. The arrangement of the connecting block 7, connecting rod 8, sleeve 9, and propeller blade 10 facilitates assembly by workers.

[0025] In some specific embodiments, a connecting plate 11 is fixedly provided at one end of the connecting shaft 2. The connecting plate 11 is detachably connected to the lower end of the drone body 1. Specifically, the upper end of the connecting plate 11 is provided with a threaded head 12 for fixing, and the other end of the connecting shaft 2 is provided with a retaining pin 13 for connection. The lower end of the retaining pin 13 is fixedly connected to a mounting plate 14 for fixing. The mounting plate 14 is detachably connected to the camera structure. Specifically, the upper end of the mounting plate 14 is provided with a bolt 15 for fixing, and the bolt 15 passes through the mounting plate 14 and is threadedly connected to the mounting shaft 3. The connection plate 11 and the threaded head 12 make it easier for the operator to fix the connecting shaft 2 more stably to the lower end of the drone body 1. At the same time, the retaining pin 13, the mounting plate 14, and the bolt 15 make it easier for the operator to fix the mounting shaft 3 to the lower end of the connecting shaft 2, further ensuring greater stability when the operator fixes the camera 5 to the lower end of the connecting shaft 2.

[0026] In some specific embodiments, the camera structure includes a mounting shaft 3 and a camera 5. The mounting shaft 3 is detachably connected to the connecting shaft 2, and a camera 5 is respectively provided on both sides of the mounting shaft 3. The mounting shaft 3 is detachably connected to the camera 5.

[0027] In some specific embodiments, an angle adjustment structure is provided on the mounting shaft 3, and the power output end of the angle adjustment structure is used for transmission connection with the camera 5.

[0028] In some specific embodiments, the angle adjustment structure includes a motor 19, a first gear, and a second gear. The motor 19 is mounted on a mounting shaft 3. The first gear is located at the power output end of the motor 19. Both the first and second gears are bevel gears, meshing with each other. Both the first and second gears are rotatable relative to the mounting shaft 3. The first gear can rotate about an axis perpendicular to the mounting shaft 3, and the second gear can rotate about the axis of the mounting shaft 3. The second gear is connected to the camera 5. When the camera 5 needs angle adjustment, the motor 19 drives the first gear to rotate. Through the first and second gears, the transmission direction is changed, causing the camera 5 to move.

[0029] In some specific embodiments, the power output end of the angle adjustment structure is provided with a rotating disk 4, which can rotate relative to the mounting shaft 3. The rotating disk 4 is detachably connected to the camera 5. Specifically, the rotating disk 4 is provided with a screw 16 for fixing, which passes through the rotating disk 4 and is threaded to the side of the camera 5.

[0030] In some specific embodiments, a locator is fixedly installed on the side of the camera 5, preferably a laser locator 20.

[0031] In some embodiments, a protective housing 18 is fixedly mounted on the upper end of the camera 5.

[0032] The screw 16 allows the operator to more stably fix the camera 5 to the end face of the rotating disk 4, further ensuring the stability of the camera 5. The gas monitoring sensor 17 can monitor the natural gas pipeline. The housing 18 can protect the camera 5, further ensuring the stability of the camera 5 during operation.

[0033] The working steps of the natural gas inspection drone in this embodiment are as follows: First, connect the connecting disc 11 of the connecting shaft 2 to the lower end of the drone body 1 to ensure a secure connection. Second, fix the camera 5 to the rotating disc 4 using screws 16. Then, after confirming that all components are securely installed, start the flight system of the drone body 1. Finally, control the drone body 1 to fly to the airspace above the natural gas system for inspection according to the preset inspection route and altitude.

[0034] This invention aims to improve the structure, while the control process is based on existing technology. The electrical components in this invention are all connected to an external main controller, which can be a conventional, known device such as a computer for control.

[0035] This embodiment of the natural gas inspection drone, through the coordinated arrangement of the drone body 1, connecting shaft 2, mounting shaft 3, rotating disk 4, and camera 5, allows for convenient installation and disassembly of each structure. This design greatly simplifies the installation and disassembly process, improves work efficiency, and allows for easy operation of the camera 5 without expending significant time and effort when maintenance or upgrades are required. This helps extend the service life of the natural gas inspection drone and ensures it is always in optimal working condition. Furthermore, since the two rotating disks 4 are rotatably mounted at both ends of the mounting shaft 3 and can be driven to rotate by the motor 19, the camera 5 can achieve angular positioning. The camera 5 adjusts the temperature, thus increasing the monitoring range. With the help of the laser locator 20, the camera 5 can detect the location of the leak and mark it, allowing staff to find the leak in time and carry out repairs. The fan blades 21 actively enhance airflow, alleviating the core problem caused by high temperature and playing a key role in improving the stable operation of the equipment. They can accelerate the dissipation of heat from the fuselage of the UAV body 1, preventing the flight control, signal module and other electronic components from malfunctioning due to high temperature, such as calculation errors, signal interruptions or overheat protection triggering, thus maintaining hovering accuracy and control responsiveness.
