[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0026] Example 1

[0027] Reference Figure 1-4 In the first embodiment of this utility model, a data acquisition component 1 is provided, including a drone 101, a support frame 102, and an imager 103. The lower end of the drone 101 is fixedly connected to the upper end of the support frame 102. The imager 103 is disposed below the drone 101. An adjustment mechanism 2 is disposed below the drone 101. A mating mechanism 3 is disposed on the surface of the adjustment mechanism 2. The adjustment mechanism 2 is used to adjust the imager 103 back and forth, and the mating mechanism 3 is used to adjust the imager 103 left and right.

[0028] Specifically, the acquisition component 1, by placing the imager 103 below the drone 101 and integrating the adjustment mechanism 2 and the cooperating mechanism 3, achieves multi-dimensional precise adjustment of the imager in the front-back and left-right directions. This structure solves the problems of low adjustment freedom, limited shooting angle, and difficulty in adapting to complex terrain of traditional drone 101 aerial photography equipment, and improves the flexibility and coverage of image acquisition. The support frame 102 ensures the overall structural stability of the system. The adjustment and cooperating mechanisms 3 work together to enable the imager 103 to dynamically adjust its position and be reliably fixed during flight, effectively ensuring the integrity, clarity and efficiency of image data in land resource surveys.

[0029] Furthermore, to ensure the comprehensiveness and accuracy of image acquisition in land resource management, the position of the image equipment needs to be flexibly adjusted. In actual operation, when it is necessary to adjust the image machine 103 back and forth, the image machine 103 can be adjusted back and forth through the adjustment mechanism 2. If it is necessary to adjust it left and right, the image machine 103 can be adjusted left and right through the cooperation mechanism 3.

[0030] Example 2

[0031] The second embodiment of this utility model provides an adjustment mechanism 2 including a protective cover 201, a servo motor 202, an adjustment screw 203, and a sliding block 204. The surface of the protective cover 201 is fixedly connected to the surface of the servo motor 202, the output end of the servo motor 202 is fixedly connected to the surface of the adjustment screw 203, the surface of the adjustment screw 203 is threadedly connected to the inner wall of the sliding block 204, the upper end of the protective cover 201 is fixedly connected to the lower end of the drone 101, the upper end of the sliding block 204 is slidably connected to the lower end of the drone 101 through a sliding groove, and the surface of the sliding block 204 is slidably connected to the inner wall of the protective cover 201 through a sliding groove.

[0032] Specifically, the adjustment mechanism 2 drives the adjustment screw 203 to rotate via the servo motor 202, and uses thread transmission to drive the sliding block 204 to move linearly along the guide rail inside the protective cover 201, thereby achieving precise adjustment of the front and rear position of the image camera 103. This structure solves the problem that the traditional fixed method cannot flexibly adjust the shooting distance and angle, and improves the adaptability and coverage of image acquisition. At the same time, the sliding block 204 and the protective cover 201 cooperate through the sliding groove to ensure smooth movement, avoid uneven load or jamming, enhance the reliability of the adjustment process, and provide a stable foundation for subsequent left and right adjustment and clamping operations.

[0033] Furthermore, when it is necessary to adjust the position of the camera 103 in the forward and backward direction, the operator can start the servo motor 202 fixed on the outer surface of the protective cover 201. The output end of the servo motor 202 is connected to one end of the adjusting screw 203, which drives the adjusting screw 203 to rotate synchronously. The adjusting screw 203 is provided with threads, and the sliding block 204 that cooperates with it is nested on its surface and slides along the screw axis under the action of thread transmission. As the servo motor 202 runs, the rotating adjusting screw 203 drives the sliding block 204 to achieve precise forward and backward linear movement on the guide rail, thereby driving the camera 103 connected to it to complete the forward and backward position adjustment to meet the needs of different shooting distances and angles.

[0034] Example 3

[0035] The third embodiment of this utility model provides a mating mechanism 3 including a fixing ring 301, a mating motor 302, a mating screw 303, a sliding plate 304, a protective sleeve 305, a fixing block 306, and a clamping plate 307. The inner wall of the fixing ring 301 is fixedly connected to the surface of the mating motor 302, the output end of the mating motor 302 is fixedly connected to the surface of the mating screw 303, the surface of the mating screw 303 is threadedly connected to the upper inner wall of the sliding plate 304, and the upper surface of the sliding plate 304 is threadedly connected to the inner wall of the protective sleeve 305. The wall is slidably connected by a sliding groove. The surface of the fixing block 306 is fixedly connected to the inner wall of the clamping plate 307. The upper end of the fixing ring 301 is fixedly connected to the lower end of the sliding block 204. The upper end of the protective sleeve 305 is fixedly connected to the lower end of the sliding block 204. The two ends of the adjusting screw 203 are rotatably connected to the inner wall of the protective sleeve 305. The inner wall of the sliding plate 304 is fixedly connected to the surface of the fixing block 306. The surface of the servo motor 202 is fixedly connected to the surface of the protective sleeve 305. The inner wall of the clamping plate 307 is in contact with the surface of the image machine 103.

[0036] Specifically, the cooperating mechanism 3 drives the cooperating screw 303 to rotate via the cooperating motor 302. The screws with opposite directions at both ends synchronously drive the sliding plate 304 and the clamping plate 307 to move in opposite directions, thereby realizing the rapid clamping and left-right adjustment of the image machine 103. This structure effectively solves the problem of the image equipment lacking stable fixation and being prone to displacement after adjustment, and improves the synchronicity and reliability of left-right adjustment. At the same time, the cooperating mechanism 3 and the front-back adjustment mechanism 2 form a linkage support through the protective sleeve 305 and the sliding block 204, ensuring the coordinated movement of the overall structure and enhancing the stability of the equipment during image acquisition.

[0037] Furthermore, after completing the initial positioning of the front and rear positions, if it is necessary to adjust the horizontal direction of the image machine 103 or clamp it for positioning, the system uses another independent mating mechanism 3. This mechanism is driven by a mating motor 302, the output of which is connected to a mating screw 303. The two ends of the mating screw 303 are rotatably connected to the inner wall of the protective sleeve 305, while the upper end of the protective sleeve 305 is fixedly connected to the lower part of the aforementioned sliding block 204, thereby forming a linkage support structure between the left and right adjustment mechanism 2 and the front and rear adjustment mechanism 2. The two ends of the mating screw 303 are respectively machined with threads of opposite directions, and two sliding plates 304 that match the threads are mounted on it. The sliding plates 304 are connected to the clamping plate through the fixing block 306. The 307 connection forms a symmetrical clamping assembly. When the motor 302 is started, the screw 303 rotates as a whole. Since the threads at both ends turn in opposite directions, the two sliding plates 304 move synchronously in opposite directions along the rod under the action of thread transmission, thereby driving the clamping plates 307 on both sides to move towards or away from each other. When the clamping plate 307 moves to the point where its inner wall contacts the surface of the outer shell of the imager 103, a stable clamping force is formed, realizing the fixation or fine-tuning positioning of the device. Since the entire mating mechanism 3 is connected with the sliding block 204 and the protective sleeve 305, the clamping action and the front and rear adjustment mechanism 2 maintain structural synchronicity and coordination, thereby ensuring that the position adjustment of the imager 103 in space is both accurate and stable.

[0038] Working principle:

[0039] To ensure the comprehensiveness and accuracy of image acquisition in land resource management, the position of the image equipment needs to be flexibly adjusted. In actual operation, when it is necessary to adjust the position of the image machine 103 in the forward and backward direction, the operator can start the servo motor 202 fixed on the outer surface of the protective cover 201. The output end of the servo motor 202 is connected to one end of the adjusting screw 203, driving the adjusting screw 203 to rotate synchronously. The adjusting screw 203 is provided with threads, and the sliding block 204 that cooperates with it is nested on its surface and is driven by the thread along the axial direction of the screw. As the servo motor 202 rotates, the adjusting screw 203 drives the sliding block 204 to move precisely forward and backward on the guide rail, thereby adjusting the position of the connected camera 103 to meet the needs of different shooting distances and angles. After the initial positioning of the forward and backward position is completed, if it is necessary to adjust the horizontal position of the camera 103 or clamp it for positioning, the system uses another independent cooperating mechanism 3. This mechanism is driven by the cooperating motor 302, and its output end is connected to the cooperating screw 303. The two ends of the cooperating screw 303 are connected to the cooperating screw 303. The upper end of the protective sleeve 305 is rotatably connected to the inner wall of the protective sleeve 305, while the lower end of the protective sleeve 305 is fixedly connected to the lower part of the aforementioned sliding block 204, thereby forming a linkage support structure between the left and right adjustment mechanism 2 and the front and rear adjustment mechanism 2. The two ends of the screw 303 are respectively machined with threads of opposite directions, and two sliding plates 304 matching the threads are mounted on it. The sliding plates 304 are connected to the clamping plate 307 through the fixing block 306, forming a left and right symmetrical clamping assembly. When the motor 302 is started, the screw 303 rotates as a whole, and due to the threads at both ends of its rotation... Conversely, the two sliding plates 304 move synchronously in opposite directions along the rod under the action of threaded transmission, thereby driving the clamping plates 307 on both sides to move towards or away from each other. When the clamping plates 307 move to their inner wall and contact the outer surface of the imager 103, a stable clamping force is formed, realizing the fixation or fine-tuning positioning of the equipment. Since the entire mating mechanism 3 is connected with the sliding block 204 and the protective sleeve 305, the clamping action and the front and rear adjustment mechanism 2 maintain structural synchronicity and coordination, thereby ensuring that the position adjustment of the imager 103 in space is both accurate and stable.

[0040] In summary, by using a servo motor to drive the adjusting screw and sliding block through threaded transmission, and by using a cooperating motor to drive a screw with reverse threads, sliding plate, and clamping plate, precise position adjustment and stable clamping of the imager in the front-back and left-right directions are achieved. The front-back adjustment mechanism and the left-right clamping mechanism form a linkage structure through the sliding block and protective sleeve, ensuring synchronization and overall stability during the adjustment process. This effectively guarantees the comprehensiveness, flexibility, and operational accuracy of image acquisition in land resource management.
