Description

Technical Field

[0001] The utility model relates to the technical field of production measurement devices, in particular to a large-span remote sensing production measurement device. Background Art

[0002] Remote sensing yield assessment generally refers to the process of monitoring and evaluating crop production using remote sensing technology. This involves controlling drones equipped with multispectral cameras and other imaging equipment to fly along predetermined routes over fields, capturing images of target objects within them and obtaining corresponding data.

[0003] When the number of acres of cultivated fields to be measured is large, the working range of remote sensing yield measurement also increases. To ensure the accuracy of remote sensing yield measurement over a large span, it is necessary to obtain images of the cultivated fields to be measured from multiple angles. However, the existing camera equipment mounted on drones only supports vertical rotation, resulting in limited shooting angles. Therefore, testers currently usually equip drones with additional tilted camera equipment to obtain images of the cultivated fields to be measured from multiple angles to ensure the accuracy of yield measurement. However, the additional camera equipment on the drone increases the drone's load, which can easily cause the drone to lose stability during flight, making it difficult to maintain focus on the yield measurement images, thus affecting the clarity of the measurement images and the accuracy of the measurement. Utility Model Content

[0004] The utility model provides a large-span remote sensing production device, which solves the problem in the related art that the drone is difficult to keep stable during the flight due to the additional shooting equipment carried on the drone.

[0005] The technical solution of the utility model is as follows:

[0006] A large-span remote sensing production inspection device includes a drone and a production inspection camera. The production inspection camera is rotatably set on the drone. The drone includes a drone body and several legs. A mounting seat is provided between the production inspection camera and the drone body. The mounting seat includes a roll bracket. The production inspection camera is rotatably connected to the roll bracket. Each of the legs is symmetrically and evenly distributed with the production inspection camera as the center; each of the legs includes a supporting leg body and a stabilizing leg body. A stabilizing bar is provided between the roll bracket and the stabilizing leg body. The two ends of the stabilizing bar are respectively fixedly connected to the roll bracket and the slidably connected to the stabilizing leg body. The projection surface of the stabilizing leg body on the vertical horizontal plane is a fan ring structure.

[0007] Furthermore, the roll bracket has a connector, the connector and the roll bracket are integrally formed, and the stabilizer bar is threadedly connected to the connector.

[0008] Furthermore, both ends of the roll bracket are provided with a stabilizing rod and a connecting body, and each stabilizing rod corresponds one-to-one to each connecting body and each stabilizing leg body.

[0009] Furthermore, each of the stabilizing legs is provided with a rotation slot, and one end of the stabilizing rod close to the stabilizing leg is slidably connected to the rotation slot.

[0010] Furthermore, one end of the stabilizing rod close to the stabilizing foot body is an arc-shaped structure.

[0011] Furthermore, there are reinforcing ribs between each supporting leg body and each stabilizing leg body.

[0012] Furthermore, the rolling bracket includes a connecting frame and a motor housing. The motor housing has a driving motor. The connecting frame is linked to the output shaft of the driving motor, and the production measurement camera is rotationally connected to the connecting frame.

[0013] Furthermore, a plurality of reinforcing ribs are provided between the connector and the rolling support, and the reinforcing ribs are evenly distributed around the circumference of the connector.

[0014] The working principle and beneficial effects of the utility model are as follows:

[0015] 1. The drone in the present invention mainly includes a drone body and several legs. The drone body is provided with a mounting base for mounting a yield measurement camera. The mounting base includes a roll bracket, and the yield measurement camera is rotatably connected to the roll bracket. With the help of the rotation function of the roll bracket itself and the rotation connection between the yield measurement camera and the roll bracket, the yield measurement camera can be rotated in four directions: up, down, left, and right. Thus, a single camera can be used to capture images of the planting field from multiple angles without the need to carry multiple cameras on the drone, thereby reducing the load of the drone and ensuring the stability of the drone during flight.

[0016] 2. Each support leg in the present invention includes a stabilizing leg body, and a stabilizing rod is provided between the roll bracket and the stabilizing leg body.

[0017] 3. The projection surface of the stabilizing foot in the present invention on the vertical horizontal plane is a fan-ring structure, so that the stabilizing rod connected to the roll bracket can move along the stabilizing foot while maintaining the connection relationship with the stabilizing foot when the roll bracket rotates, ensuring that the connection relationship between the stabilizing foot, the stabilizing rod and the roll bracket will not affect the normal rotation of the roll bracket.

[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1-2 、 Figure 7 As shown, this embodiment proposes a large-span remote sensing production inspection device, which mainly includes a drone 1 and a production inspection camera 2. The production inspection camera 2 is rotatably arranged on the drone 1, so that the production inspection camera 2 can be rotated at multiple angles on the drone 1, rather than being limited to rotation in the up and down directions.

[0030] Specifically, the drone 1 mainly includes a drone body 11 and several legs 12. The legs 12 support the drone body 11 when the drone body 11 has not taken off, ensuring that the drone body 11 remains stable when taking off and landing on the ground, preventing the drone body 11 from tipping over during take-off and landing, and ensuring the safety of this embodiment.

[0031] There is a mounting base 3 between the production test camera 2 and the drone body 11, so that the production test camera 2 can be installed (mounted) on the drone body 11; the mounting base 3 includes a roll bracket 31, and the production test camera 2 is rotatably connected to the roll bracket 31. Specifically, the roll bracket 31 mainly includes a connecting frame 312 and a motor housing 313. The motor housing 313 has (is fixedly provided with) a drive motor, that is, the motor housing 313 plays a role in protecting the drive motor, and the connecting frame 312 is linked with the output shaft of the drive motor so that the rotation of the connecting frame 312 is controlled by the drive motor; the production test camera 2 is rotatably connected to the connecting frame 312. Specifically, a rotating motor is mounted (fixedly arranged) on the connecting frame 312, and the yield measurement camera 2 is linked to the output shaft of the rotating motor so that the rotation of the yield measurement camera 2 is controlled by the rotating motor. In summary, the rotation of the yield measurement camera 2 and the rotation of the connecting frame 312 are both controlled by motor-type electronic controls, so that during the flight of the drone body 11, the yield measurement personnel can change the shooting angle of the yield measurement camera 2 by rotating the yield measurement camera 2 itself or by rotating the connecting frame 312 on which the yield measurement camera 2 is installed, thereby realizing multi-angle shooting of the planting field to be measured.

[0032] Specifically, the rotation direction of the output shaft of the rotating motor and the rotation direction of the output shaft of the driving motor form a "+" structure on the horizontal projection surface, thereby realizing the rotation of the production measurement camera 2 in four directions of up, down, left and right.

[0033] The rotating motor and the driving motor in this embodiment are preferably motors with precise control performance, such as servo motors, so as to ensure the accuracy of adjusting the angle of the production measurement camera.

[0034] The supporting legs 12 are symmetrically and evenly distributed around the production measurement camera 2 , that is, the production measurement camera 2 is located between adjacent supporting legs 12 , so that the supporting legs 12 can protect the production measurement camera 2 to a certain extent.

[0035] The stabilizing rod 4 is connected to the stabilizing leg 122 by the support rod 121, and the support rod 122 is connected to the support rod 121 by the support rod 122.

[0036] Because each leg 12 in this embodiment is bifurcated to form a supporting leg 121 and a stabilizing leg 122, this bifurcated structure is prone to shaking when encountering sudden airflow during flight. Therefore, a reinforcing rib 123 is provided between each supporting leg 121 and each stabilizing leg 122. The reinforcing rib 123 connects the stabilizing leg 122 and the supporting leg 121, effectively resisting the tension and other forces generated by shaking due to wind, thereby enhancing the overall stability of the leg 12.

[0037] like Figure 3 As shown, the projection surfaces of the stabilizing foot 122 and the rotating slide groove 1221 provided thereon in the present embodiment on the vertical horizontal plane are both fan-ring structures, that is, each stabilizing foot 122 or each rotating slide groove 1221 is on a unified circular trajectory, thereby preventing the stabilizing bar 4 connected to the roll bracket 31 from interfering with the stabilizing foot 122 during the rotation process, so that the stabilizing bar 4 can move along the stabilizing foot 122 while maintaining the connection relationship of the stabilizing foot 122, that is, the connection relationship among the stabilizing foot 122, the stabilizing bar 4 and the roll bracket 31 will not affect the normal rotation operation of the roll bracket 31, thereby ensuring the smoothness of the rotation of the production measurement camera 2 in this direction.

[0038] like Figure 2 、 Figures 4-5As shown, the roll bracket 31 in this embodiment has a connector 311, and the connector 311 and the roll bracket 31 are integrally formed. Specifically: the connector 311 and the connecting frame 312 are integrally formed, which fully ensures the connection strength between the two; the stabilizer bar 4 is threadedly connected to the connector 311, that is, the fixed connection between the stabilizer bar 4 and the connecting frame 312 (connector 311) is achieved by threaded connection, which not only ensures the reliability of the connection between the two, but also facilitates the later disassembly, assembly, repair and maintenance of this embodiment, killing two birds with one stone; and the existence of the connector 311 ensures that the connecting frame 312 has enough space to be threadedly connected to the stabilizer bar 4, preventing the threaded connection between the connecting frame 312 and the stabilizer bar 4 from squeezing out the internal space of the connecting frame 312 for loading the rotating motor.

[0039] Both ends of the roll bracket 31 have a stabilizing rod 4 and a connecting body 311. Each stabilizing rod 4 corresponds one-to-one to each connecting body 311 and each stabilizing foot body 122. That is, both sides of the roll bracket 31 can have a supporting stabilizing point on the corresponding stabilizing foot body 122 through the stabilizing rod 4, so that the production measurement camera 2 in this embodiment can be more stable during the rotation process.

[0040] A plurality of reinforcing ribs 5 are provided between each connector 311 and the roll bracket 31. Each reinforcing rib 5 has a triangular structure. That is, the strong characteristic of the triangular structure is utilized to further improve the connection strength between the connector 311 and the connecting frame 312, thereby preventing the connector 311 from being deformed by force during use of the present embodiment, thereby causing its internal thread features to be scrapped. The reinforcing ribs 5 are evenly distributed around the circumference of the connector 311, thereby avoiding reinforcement dead angles between the connector 311 and the connecting frame 312, thereby fully ensuring the overall structural strength and service life of the present embodiment.

[0041] like Figure 3 、 Figure 6 As shown, the end of the stabilizing bar 4 in this embodiment close to the stabilizing foot body is an arc-shaped structure, that is, the stabilizing bar 4 slides in the rotating groove 1221 in a point contact manner, effectively reducing the contact area between the stabilizing bar 4 and the rotating groove 1221, thereby reducing the friction generated during the movement, so that each stabilizing bar 4 can move more smoothly in the corresponding rotating groove 1221.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
