[0036] This utility model proposes a wind farm unmanned aerial vehicle (UAV) intelligent patrol device 1000.

[0037] Please see Figure 1 , Figure 3 and Figure 4 In one embodiment of this utility model, the wind farm drone intelligent patrol equipment 1000 includes a body 1, a positioning component, a rotor component 2, a shooting device 3, and an installation component; the positioning component and the rotor component 2 are disposed on the body 1; the installation component includes a telescopic rod 4, a first mounting base 5, and a second mounting base 6, the telescopic rod 4 is disposed at one end of the body 1, the first mounting base 5 is disposed at one end of the telescopic rod 4, and the second mounting base 6 is detachably connected to the first mounting base 5; the shooting device 3 is disposed on the second mounting base 6.

[0038] The body 1 is made of high-strength, lightweight carbon fiber composite material to ensure sufficient load-bearing capacity.

[0039] The telescopic boom 4 is made of high-strength aluminum alloy, with one end fixedly installed inside the fuselage 1. It can extend and retract via a motor. The telescopic boom 4 has a large extension range, allowing its length to be adjusted during flight according to actual inspection needs, thus extending the imaging device 3 to a suitable position to obtain clearer and more comprehensive equipment image information. Furthermore, by setting the installation position of the telescopic boom 4, it can be completely retracted into the fuselage 1, bringing the imaging device 3 inside for protection.

[0040] In the technical solution of this utility model, the first mounting base 5 and the second mounting base 6 are designed to be detachable, so that the first mounting base 5 and the second mounting base 6 can be quickly separated, thereby realizing the separation of the shooting device 3 and the body 1, which facilitates the inspection and replacement of the shooting device 3.

[0041] There are various ways to detach the connection, such as using magnetic attraction and snap-fit. In one embodiment of this utility model, please refer to... Figure 3 and Figure 4 The second mounting base 6 has a connecting post 61 on the side facing the first mounting base 5, and the connecting post 61 forms a through hole; the first mounting base 5 has a sliding groove in the middle; the mounting assembly also includes a slider 7, which is slidably disposed in the sliding groove, and has a locking rod 71 in the middle of the slider 7, which passes through the through hole. The slider 7 is made of wear-resistant plastic or nylon material, has self-lubricating properties and good fatigue resistance, and can withstand frequent sliding friction and repeated locking operations. In actual use, after sliding the slider 7 to the appropriate position, the locking rod 71 can be inserted and locked, thus completing the connection between the first mounting base 5 and the second mounting base 6; conversely, by unlocking the locking rod 71 and sliding the slider 7, the first mounting base 5 and the second mounting base 6 can be easily separated, realizing the separation of the shooting device 3 and the camera body 1, which is convenient for the inspection and replacement of the shooting device 3. The size and shape of this mounting assembly can be appropriately adjusted and customized according to different models of shooting devices 3, and has strong versatility and adaptability. For example, different specifications of second mounting bases 6 can be used to mount different models of shooting devices 3, but the connecting posts 61 of these second mounting bases 6 are the same size, so they can be connected to the first mounting base 5 of the same specification.

[0042] Furthermore, in one embodiment of this utility model, please refer to... Figure 3 and Figure 4 The first mounting base 5 has a mounting groove communicating with the slide rail; the slider 7 has a connecting arm 72, which is located within the mounting groove; the mounting assembly also includes a spring 8, which is located within the mounting groove and connects the connecting arm 72 to the side wall of the mounting groove. The main function of the spring 8 is to provide a stable restoring force for the slider 7. When the slider 7 slides within the slide rail, the spring 8 can automatically return it to its initial position after the slider 7 moves. This automatic reset function ensures that the locking lever 71 can quickly reset after unlocking, thus preparing for the next locking operation. In addition, the spring 8 also has a certain buffering and shock absorption function, which can reduce the impact of vibration or impact on the shooting device 3 during the flight of the UAV, further improving the stability and service life of the shooting device 3.

[0043] Specifically, in one embodiment of this utility model, the first mounting base 5 is provided with two mounting slots; the slider 7 has two connecting arms 72, which are located on opposite sides of the slider 7, and each connecting arm 72 is disposed in a mounting slot; the mounting assembly includes two springs 8, each spring 8 is disposed in a mounting slot and connects a connecting arm 72 to the side wall of a mounting slot. The design of the double springs 8 makes the reset force of the slider 7 more uniform and reliable. The simultaneous action of the two springs 8 ensures that the slider 7 can reset quickly and stably.

[0044] Furthermore, in one embodiment of this utility model, please refer to... Figure 3 and Figure 4 The bottom wall of the chute is provided with a positioning hole 51, into which the connecting post 61 is inserted. The positioning hole 51 is a cylindrical structure, and its axis is perpendicular to the length direction of the chute. The size of the positioning hole 51 matches the outer diameter of the connecting post 61, and the two adopt a transition fit to ensure that the connecting post 61 can be smoothly inserted into the positioning hole 51, while ensuring a certain positioning accuracy and stability. The fit between the positioning hole 51 and the connecting post 61 provides a precise positioning reference for the second mounting base 6, facilitating the connection between the first mounting base 5 and the second mounting base 6.

[0045] Furthermore, in one embodiment of this invention, the imaging device 3 is a visible light camera or an infrared camera. In practical applications, the visible light camera and the infrared camera can be flexibly switched or combined according to different task requirements and environmental conditions. For example, under normal daylight conditions, the visible light camera is mainly used for environmental monitoring and image acquisition; while at night or in low-light environments, the infrared camera is switched to ensure that effective image information can be continuously acquired.

[0046] Specifically, in one embodiment of this utility model, please refer to... Figure 2 The positioning components include a lidar 9 and an IMU module 10 mounted on the fuselage 1. The lidar 9, installed on the fuselage 1, measures the precise distance between the drone and surrounding objects by emitting a laser beam and receiving reflected light. The IMU module 10, also mounted on the fuselage 1, measures the drone's acceleration and angular velocity. The IMU module 10 typically includes three-axis accelerometers and three-axis gyroscopes, enabling real-time sensing of the drone's motion in space, including acceleration, angular velocity, and attitude changes. Using this data, the controller can precisely control the drone's flight attitude, ensuring its stability and safety during flight.

[0047] To improve the accuracy of control, in one embodiment of this utility model, please refer to... Figure 2The wind farm drone intelligent patrol equipment 1000 also includes a drive motor 11 and a rotating frame 12. The drive motor 11 is located on the body 1, and the rotating frame 12 includes a horizontal plate and a vertical plate connected together. The horizontal plate is connected to the output end of the drive motor 11. The lidar 9 is located on the vertical plate, and the IMU module 10 is located on the horizontal plate. The rotating frame 12 consists of a horizontal plate and a vertical plate, with the horizontal plate connected to the output end of the drive motor 11. The horizontal and vertical plates are made of high-strength, lightweight materials to ensure structural stability and durability. Furthermore, the design of the vertical and horizontal plates fully considers the installation requirements of the lidar 912 and the IMU module 10, providing suitable installation interfaces and fixing structures. Driven by the drive motor 11, the rotating frame 12 can rotate around a certain axis of the body 1, thereby changing the orientation of the lidar 9 and the IMU module 10. This design allows the lidar 9 to scan a wider space and acquire more comprehensive environmental information; simultaneously, the IMU module 10 can sense the movement state of the drone in different attitudes during rotation, further improving the accuracy of positioning and attitude control.

[0048] Specifically, in one embodiment of this utility model, the fuselage 1 has four arms; the rotor assembly 2 includes four wings and four drive components. Each wing is located on one arm, and each drive component is located on one arm and drives one wing to rotate. The four arms are evenly distributed around the center point of the fuselage 1, forming a stable quadrilateral frame. This structural design not only enhances the overall strength and stability of the fuselage 1 but also provides ample space and support for the installation of the rotor assembly 2. Each arm is made of lightweight but high-strength materials, such as carbon fiber composite materials, to reduce the weight of the UAV while ensuring it can withstand various loads and stresses during flight. Each wing is installed at the end of one arm, and the wing adopts a highly efficient aerodynamic design, possessing good lift characteristics and anti-interference capabilities. Each drive component is also installed on the corresponding arm and connected to the wing, used to drive the high-speed rotation of the wing. The drive components are typically brushless motors, characterized by high efficiency, high torque, and low noise, providing strong power output to ensure stable flight and agile maneuverability of the UAV. The four-arm structure and the evenly distributed design of the four rotors make the drone's center of gravity more stable and its flight attitude more balanced.

[0049] Furthermore, in one embodiment of this utility model, please refer to... Figure 1The rotor assembly 2 also includes four protective rings 13, each located on one arm and surrounding one wing. The protective rings 13 are made of lightweight, high-strength engineering plastics or carbon fiber materials, possessing good toughness, impact resistance, and wear resistance. The protective rings 13 have a circular or elliptical ring structure, with an inner diameter slightly larger than the wing's diameter, allowing them to tightly wrap around the wing without affecting its normal rotation. Each protective ring 13 is mounted on an arm and connected to it via clips, bolts, or a dedicated mounting bracket, ensuring stability during drone flight. The position of the protective rings 13 is precisely adjusted to maintain an appropriate gap with the wing, preventing friction or interference during high-speed wing rotation. The protective rings 13 effectively prevent direct collisions between the wing and obstacles during flight, avoiding wing damage or drone loss of control due to collisions.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
