Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a UAV inspection gimbal device with multi-angle adjustment. Background Technology

[0002] A drone inspection gimbal is a device installed on a drone to carry various inspection equipment, such as cameras, infrared thermal imagers, and lidar, enabling multi-angle, high-precision shooting and monitoring. It plays a crucial role in industrial inspection fields such as power line inspection, oil and gas pipeline inspection, photovoltaic power station inspection, and infrastructure maintenance.

[0003] Existing drone inspection gimbals still have certain limitations in their structural design. On the one hand, their angle adjustment function is relatively limited, usually only able to fix the camera at a few preset specific angles, making it difficult to make flexible and precise angle adjustments according to the complex and ever-changing needs of actual inspection scenarios, thus failing to meet diverse and high-precision shooting requirements. On the other hand, most gimbals are directly installed on the drone shell using a fixed connection method, resulting in cumbersome and time-consuming operations during disassembly or replacement, which is not conducive to the rapid switching of different functional modules and the timely maintenance and replacement of faulty parts, thereby affecting the efficiency of the overall inspection operation and the flexibility of system operation.

[0004] Therefore, there is a particular need for a multi-angle adjustable drone inspection gimbal device to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing drone inspection gimbals, such as inflexible angle adjustment, inconvenient assembly and disassembly, and reduced operational efficiency and functional expandability, this utility model provides a drone inspection gimbal device with multi-angle adjustment.

[0006] This utility model is achieved through the following technical approach: A multi-angle adjustable drone inspection gimbal device, comprising a drone body, a waterproof connector one, a waterproof connector two, limiting rods, a mounting frame, a sleeve, a locking assembly, a connecting frame one, a servo motor one, a connecting frame two, a servo motor two, a waterproof shell, protective glass, and a camera. The waterproof connector one is located on one side of the lower part of the drone body. Multiple limiting rods arranged in a U-shape are fixed to the lower part of the drone body, and the mounting frame is inserted between the multiple limiting rods. The waterproof connector two is located on one side of the mounting frame, and the sleeve is fixed to the mounting frame. At the top, the locking component is located between the drone body and the sleeve. Connecting bracket one is fixed to the lower part of the mounting bracket, on which servo motor one is mounted. The output shaft of servo motor one extends to the right and is fixed to connecting bracket two. Connecting bracket two is mounted on servo motor two. The output shaft of servo motor two extends forward and is fixed to a waterproof shell. Protective glass is installed on one side of the waterproof shell. Connecting bracket one, servo motor one, connecting bracket two, servo motor two, waterproof shell and protective glass together form a gimbal structure. The camera is installed inside the waterproof shell, and its shooting lens is aimed at the protective glass.

[0007] Furthermore, the locking assembly includes a conical block, a wedge block, a spring, a support plate, a slide rod, and a lever. The conical block is fixed to the lower part of the UAV body and located between multiple limit rods. Two support plates are arranged side by side and fixed to the top of the mounting frame and distributed on both sides of the sleeve. A slide rod is slidably arranged on the upper part of each support plate. A wedge block is fixed to one end of each slide rod near the sleeve. The wedge block is located in a preset groove in the sleeve and forms a tight contact with the conical block. A spring is sleeved on the outside of each slide rod. The two ends of each spring are fixedly connected to the corresponding wedge block and the corresponding support plate, respectively. A lever is fixed to the other end of each slide rod away from the sleeve.

[0008] Furthermore, it also includes a bearing seat, a drive motor, a support frame, a reciprocating screw, and a cleaning block. The support frame is installed on the upper side of the waterproof shell, and two bearing seats are fixedly connected inside it. The reciprocating screw is rotatably located between the two bearing seats. The drive motor is installed on the inner side of the support frame, and its output shaft extends to the left and is fixedly connected to one end of the reciprocating screw through a coupling. The connecting block is threaded on the outside of the reciprocating screw and forms a sliding fit with the support frame. The cleaning block is fixed on the connecting block, and its working surface is in close contact with the surface of the protective glass. The lowest point of the cleaning block is at the same horizontal height as the bottom of the protective glass.

[0009] Furthermore, it also includes guide rods, with two guide rods fixedly connected between the two bearings, and the guide rods slidingly connected to the connecting block.

[0010] Furthermore, it also includes heat dissipation fins, with heat dissipation fins provided on the rear, left, and right surfaces of the waterproof casing.

[0011] Furthermore, a buffer layer is wrapped around the cylindrical surface of each limiting rod.

[0012] Beneficial effects: 1. By using servo motor one and servo motor two to realize the angle adjustment of the camera in the horizontal and vertical directions respectively, the camera can be flexibly and accurately adjusted in three-dimensional space to meet the needs of different inspection scenarios, improve the comprehensiveness and accuracy of inspection, obtain richer and more detailed inspection information, and provide stronger support for inspection decision-making.

[0013] The mounting bracket and the drone body can be quickly installed and removed by locking components. When it is necessary to replace inspection equipment with different functions or maintain the connecting bracket, no complicated tools and cumbersome operations are required. Disassembly can be completed simply by turning the lever, which greatly improves work efficiency, reduces downtime of inspection operations, and enhances the flexibility and maintainability of the equipment.

[0014] 2. An automatic cleaning system consisting of a motor, a reciprocating lead screw, and a cleaning block can clean the protective glass surface in a timely manner when there are stains, ensuring that the camera always maintains good shooting clarity and avoiding blurry images caused by stains on the protective glass, thus guaranteeing the quality and reliability of inspection data.

[0022] Example: A multi-angle adjustable UAV inspection gimbal device, such as... Figures 1-6 As shown, the device includes a drone body 1, a waterproof connector 1 2, a waterproof connector 2 201, limiting rods 3, a mounting bracket 5, a sleeve 6, a locking assembly, a connecting bracket 1 12, a servo motor 1 121, a connecting bracket 2 122, a servo motor 2 123, a waterproof shell 13, a protective glass 131, a camera 132, and heat dissipation fins 20. The waterproof connector 1 2 is located on the lower right side of the drone body 1. Four limiting rods 3 arranged in a U-shape are fixed to the lower part of the drone body 1. The mounting bracket 5 is inserted between the four limiting rods 3. Each limiting rod 3 has a rubber buffer layer wrapped around its cylindrical surface to ensure greater stability and reduce wear when inserted into the mounting bracket 5. The waterproof connector 2 201 is located on the right side of the mounting bracket 5. The sleeve 6 is fixedly connected to the top of the mounting bracket 5. The locking assembly is located between the drone body 1 and the sleeve 6. The connecting bracket 1 12 is fixedly connected to the lower part of the mounting bracket 5, and a servo motor is bolted to it. Servo motor 121 extends to the right and is fixedly connected to connecting frame 122. Servo motor 123 is bolted to connecting frame 122. Servo motor 123 extends forward and is fixedly connected to waterproof housing 13. Protective glass 131 is bolted to the front of waterproof housing 13. Connecting frame 121, servo motor 122, connecting frame 123, waterproof housing 13, and protective glass 131 together form a gimbal structure. Camera 132 is bolted inside waterproof housing 13, and its lens is aimed at protective glass 131, allowing it to capture external scenes through protective glass 131. Heat dissipation fins 20 are provided on the rear, left, and right sides of waterproof housing 13, which helps dissipate the heat generated by camera 132 during operation, preventing performance degradation or damage due to overheating and extending the service life of camera 132.

[0023] like Figure 3 and Figure 4As shown, the locking assembly includes a conical block 4, a wedge block 7, a spring 8, a support plate 9, a slide rod 10, and a lever 11. The conical block 4 is fixedly connected to the lower part of the UAV body 1 and is located between the four limiting rods 3. Two support plates 9 are arranged side by side and fixedly connected to the top of the mounting bracket 5 and distributed on the left and right sides of the sleeve 6. A slide rod 10 is slidably arranged on the upper part of each support plate 9. A wedge block 7 is fixedly connected to one end of each slide rod 10 near the sleeve 6. The wedge block 7 is located in a preset groove in the sleeve 6 and forms a tight contact with the conical block 4. Through this contact, the gimbal structure is fixed to the UAV body 1. A spring 8 is sleeved on the outside of each slide rod 10. The two ends of each spring 8 are fixedly connected to the corresponding wedge block 7 and the corresponding support plate 9, respectively, to provide a reset force for the wedge block 7. A lever 11 is fixedly connected to the other end of each slide rod 10 away from the sleeve 6.

[0024] like Figure 5 and Figure 6 As shown, it also includes a bearing seat 14, a drive motor 15, a support frame 16, a reciprocating lead screw 17, a guide rod 18, and a cleaning block 19. The support frame 16 is bolted to the upper front side of the waterproof shell 13, and two bearing seats 14 arranged side by side are fixedly connected inside it. The reciprocating lead screw 17 is rotatably disposed between the two bearing seats 14. The drive motor 15 is bolted to the right side inside the support frame 16, and its output shaft extends to the left and is fixedly connected to the right end of the reciprocating lead screw 17 through a coupling. The connecting block 191 is threaded. The cleaning block 19 is fixedly connected to the connecting block 191 and is placed outside the reciprocating lead screw 17 and forms a sliding fit with the support frame 16. Its working surface is in close contact with the surface of the protective glass 131, and the lowest point of the cleaning block 19 is at the same level as the bottom of the protective glass 131, so as to ensure that the cleaning block 19 can fully wipe the surface of the protective glass 131 during the reciprocating movement. Two guide rods 18 are fixedly connected between the two bearing seats 14 and are distributed vertically. The guide rods 18 pass through the connecting block 191 and are slidably connected to it.

[0025] When the gimbal needs to be installed, the mounting bracket 5 is aligned with the four limiting rods 3 at the bottom of the drone body 1 and inserted, so that the sleeve 6 is close to the conical block 4. As the mounting bracket 5 is inserted, the conical block 4 gradually enters the sleeve 6 and contacts the inclined surface of the wedge block 7, squeezing the wedge block 7. After the wedge block 7 is squeezed, it moves away from the sleeve 6 by compressing the spring 8 through the slide rod 10. When the mounting bracket 5 is inserted into place, the elastic force of the spring 8 makes the wedge block 7 return to its original position and form a tight contact with the conical block 4, thereby achieving a stable lock between the mounting bracket 5 and the drone body 1.

[0026] When the gimbal needs to be disassembled, the lever 11 is moved outward. The lever 11 moves the slide rod 10 outward, which in turn moves the wedge block 7 outward, separating the wedge block 7 from the cone block 4. At this time, the mounting bracket 5 is no longer constrained by the locking component, and the mounting bracket 5 can be pulled out from the limit rod 3 to complete the disassembly operation.

[0027] During the inspection, servo motor 121 starts, and its output shaft drives the connecting bracket 122 to rotate around the output shaft axis of servo motor 121, thereby realizing the angle adjustment of camera 132 in the pitch direction. Servo motor 123 starts, and its output shaft drives the waterproof shell 13 to rotate around the output shaft axis of servo motor 123, thereby realizing the angle adjustment of camera 132 in the yaw direction. By controlling the rotation of servo motor 121 and servo motor 123, camera 132 can be flexibly adjusted to multiple angles in three-dimensional space to meet the shooting needs of different inspection scenarios.

[0028] When dust or stains on the surface of the protective glass 131 affect the shooting, the drive motor 15 is started. The output shaft of the drive motor 15 drives the reciprocating lead screw 17 to rotate, causing the connecting block 191 to reciprocate linearly along the reciprocating lead screw 17. The connecting block 191 drives the cleaning block 19 to reciprocate on the surface of the protective glass 131, thereby cleaning the surface of the protective glass 131 and ensuring the shooting clarity of the camera 132. After cleaning is completed, the drive motor 15 is turned off.
