[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] like Figure 1-3 As shown, an aerial photogrammetry device with good stability includes a connection seat 1 for fixing on a drone and a measuring device 2 for photogrammetry. The measuring device 2 specifically refers to a mainframe in an aerial photogrammetry device with good stability with a publication number of CN219284280U, which is used for photogrammetry. The bottom surface of the connection seat 1 is rotatably connected to a worm gear ring 9, and the inner side wall of the worm gear ring 9 is fixedly connected to a mounting seat 11 for articulating the measuring device 2, and one side of the bottom surface of the worm gear ring 9 is fixedly connected to a connecting plate 16. By rotating the worm gear ring 9, the mounting seat 11 can drive the measuring device 2 and the connecting plate 16 to rotate. In addition, as shown in the figure, the connecting plate 16 is arranged in the plane where the swing direction of the measuring device 2 is located. Because the connecting plate 16 The inner wall is rotatably connected to a screw rod 5, and a lifting frame 6 is threadedly connected to the screw rod 5 and is sleeved on the side of the connecting plate 16. One side of the lifting frame 6 is rotatably connected to a connecting arm 4. The connecting arm 4 is rotatably connected to an anti-skid pad 3 for fixing on the measuring device 2 while it is movable, and the connecting arm 4 is used to drive the measuring device 2 to swing. The anti-skid pad 3 is fixed to the measuring device 2 by a clamp or bolts. Therefore, when the screw rod 5 rotates, the lifting frame 6 threadedly connected to the screw rod 5 can only be raised and lowered with the rotation of the screw rod 5 due to the restriction of the connecting plate 16, and then under the connecting action of the connecting arm 4, the angle adjustment of the measuring device 2 is realized. Combined with the worm gear ring 9 to drive the measuring device 2 and the connecting plate 16 to rotate, the multi-angle direction adjustment of the lens angle of the measuring device 2 can be realized.

[0022] Further discussion: The inner wall of the worm gear ring 9 is symmetrically fixedly connected with two springs 10 for clamping with the end faces of the measuring device 2 in the swinging direction of the measuring device 2. The function of the spring 10 is that when the measuring device 2 is swung by the traction and pushing action of the connecting arm 4, the spring 10 on the corresponding side can be elastically stretched, and the thrust generated by the connecting arm 4 on the measuring device 2 and the reaction tension of the spring 10 on the measuring device 2 can be utilized to achieve the position stability of the measuring device 2.

[0023] Further discussion: The top end of the screw rod 5 passes through the connecting plate 16 and extends outward to be fixedly connected to the worm gear block 7. The top edge of the connecting plate 16 is rotatably connected to two worms 15 that are respectively meshed with the worm ring 9 and the worm gear block 7. The same side end faces of the two worms 15 are fixedly connected to a connecting bevel gear 14. The connecting plate 16 is plugged with a motor 12. The main shaft of the motor 12 is fixedly connected to two driving bevel gears 13. The two driving bevel gears 13 are respectively used to mesh with the two connecting bevel gears 14. The connecting plate 16 is fixedly connected to an electric pusher for driving the motor 12 to move. Rod 8, two driving bevel gears 13 are used alternately, and the electric push rod 8 is extended and retracted to realize the movement of the motor 12, that is, one of the driving bevel gears 13 on the main shaft of the motor 12 is meshed with the connecting bevel gear 14 on the end face of the worm 15 close to the worm gear ring 9, or the other driving bevel gear 13 is meshed and connected with the connecting bevel gear 14 on the end face of the worm 15 close to the worm gear block 7. By adjusting the position of the motor 12, the motor 12 can drive one of the worms 15 to rotate, and the worm gear ring 9 or the worm gear block 7 can be rotated, thereby realizing the rotation or swing of the measuring device 2.

[0024] Working principle: when in use, the connecting seat 1 is installed on the drone, and then the electric push rod 8 is extended and retracted to realize the movement of the motor 12 until one of the driving bevel gears 13 on the main shaft of the motor 12 is meshed with the connecting bevel gear 14 at the end face of the worm 15 close to the worm gear ring 9, and then the motor 12 drives the driving bevel gear 13 to rotate, that is, the connecting bevel gear 14 at the end face of the worm 15 close to the worm gear ring 9 is rotated, and then the worm 15 at the corresponding position is rotated, that is, the worm gear ring 9 at the corresponding position is rotated to realize the measuring device 2 to drive the connecting plate 16 to rotate, or the motor 12 is driven by the electric push rod 8, and the other driving bevel gear 13 is meshed and connected with the connecting bevel gear 14 at the end face of the worm 15 close to the worm gear block 7, and then the motor 12 drives the driving bevel gear 13 to rotate, that is, the connecting bevel gear 14 at the end face of the worm 15 close to the worm gear block 7 is rotated, and then the worm 15 at the corresponding position is rotated, that is, the worm gear block 7 at the corresponding position drives the screw 5 to rotate, and the measuring device 2 swings.

[0025] The wiring diagram of the measuring device 2, the electric push rod 8 and the motor 12 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the measuring device 2, the electric push rod 8 and the motor 12 are no longer explained in detail.
