Description

Technical Field

[0002] UAV aerial survey is a powerful supplement to traditional aerial photogrammetry. It has the characteristics of flexibility, high efficiency, precision, low operating cost, wide application range and short production cycle. It has obvious advantages in the rapid acquisition of high-resolution images in small areas and areas with difficult flight. With the development of UAV and digital camera technology, digital aerial photography technology based on UAV platform has shown its unique advantages. The mechanical anti-shake technology of UAV gimbal is widely used in aerial photography, environmental monitoring and other fields. Its advantage is that it can significantly improve the stability and clarity of the captured image, reduce the blur and ghosting caused by shaking, and improve the surveying and mapping accuracy.

The lower end head 500 includes a lower seat plate 510, and vertical frames 520 are fixedly connected to both sides of the top surface of the lower seat plate 510. An annular frame 550 is fixedly connected between the top ends of the two vertical frames 520, and four receiving plates 2 560 are fixedly connected in an annular manner at equal angles to the outer wall of the annular frame 550. The four receiving plates 2 560 correspond one to one to the four receiving plates 1 130.

[0039] Embodiment 1

[0040] like Figures 5 to 7As shown, in this embodiment, the upper receiving assembly 200 includes a fixing frame 210, and a fixing plate 140 is fixedly connected between the outer side walls of both sides of the fixing frame 210 and the upper seat plate 110. There are two transverse frames 230, which are respectively fixed to the positions on both sides of the fixing frame 210. Both ends of the fixing frame 210 are fixedly connected to the sleeve seat 220. Both sides of one end of the outer sleeve 250 are fixedly connected to the shaft rod 251. One end of the shaft rod 251 is fixedly sleeved with a gear 252. The inside of the gear 252 is fixedly installed with the magnetic block, and the outer side of the shaft rod 251 is fixedly mounted with the magnetic block. The side wall is slidably connected to the inner wall of the outer sleeve 250, there are two tooth plates 240, and they are located above the transverse frame 230, the tooth plate 240 is fixedly connected to the fixed frame 210, the tooth plate 240 is meshed with the adjacent gear 252, two screw rods 700 are arranged between the upper supporting component 200 and the lower supporting component 300, and the two ends of the fixed frame 210 are fixedly connected with the socket seats 220, the screw rod 700 is slidably socketed with the two adjacent socket seats 220, and the top end of the screw rod 700 is screwed with a nut 710.

[0041] In this embodiment, the nut 710 is rotated to adjust the distance between the upper supporting component 200 and the lower supporting component 300, thereby adjusting the distance between the two magnetic blocks. Since the magnet 540 is located between the two magnetic blocks, the upward and downward fluctuation amplitude of the magnet 540 is adjusted by adjusting the distance between the two magnetic blocks.

[0042] like Figure 4 , 8 As shown, in this embodiment, a side wall of the receiving plate 2 560 and the corresponding receiving plate 1 130 close to each other is an arc-shaped surface, and a side wall of the receiving plate 1 130 is provided with an edge platform.

[0043] In a specific implementation, when the corresponding receiving plate 1 130 and receiving plate 2 560 move closer to each other, the balloon 600 is squeezed, so that the rebound force of the balloon 600 increases, thereby facilitating the distance between the receiving plate 1 130 and the balloon 600 to return to the initial position. By setting the arc surface of the side wall of the receiving plate 1 130, when the receiving plate 1 130 and the receiving plate 2 560 are staggered to both sides, the balloon 600 is further squeezed, so that when the balloon 600 rebounds, the receiving plate 1 130 and the receiving plate 2 560 are driven to move back to the initial position. 60 is realigned, thereby limiting the rotation of the lower end head 500 in the horizontal direction, and limiting the movement of the lower end head 500 in the horizontal direction, and the balloon 600 is located between the receiving plate 1 130 and the receiving plate 2 560 and is not fixedly connected to the receiving plate 1 130 and the receiving plate 2 560. When the receiving plate 1 130 and the receiving plate 2 560 are misaligned, the balloon 600 is rubbed. Compared with the existing rubber ball fixing method, the receiving plate 2 560 has a larger movable range, which is convenient for adapting to the up and down movement of the lower end head 500.

[0044] Embodiment 2

[0045] On the basis of the first embodiment, in order to facilitate the flipping of the magnetic block in the first embodiment, the connection state between the upper end head 100 and the lower end head 500 can be changed as needed.

[0046] like Figures 4 to 7 As shown, in this embodiment, the flip assembly 400 includes two mounting plates 410, the mounting plates 410 are fixedly connected to the top surface of the fixing frame 210, and both ends of the mounting plates 410 are fixedly connected with fixing ears 420, and a screw rod 430 is rotatably connected between the top ends of the two fixing ears 420, and a long groove 411 is provided on the top surface of the mounting plate 410, and an internal thread seat 440 is screwed and connected to the outer wall of the screw rod 430, and a driving rod 450 is fixedly connected to the bottom end of the internal thread seat 440, and the top end of the driving rod 450 is slidably connected to the inner wall of the long groove 411, and a sliding groove 451 is provided on the outer wall of the driving rod 450, and the shaft rod 251 is connected to the adjacent side The inner wall of the slide groove 451 is slidably connected, one end of the fixed frame 210 is located between one end of the two screw rods 430 and is fixedly connected with a transmission box 460, and the two screw rods 430 are synchronously driven through the transmission box 460, one end of the fixed frame 210 is fixedly connected with a drive motor 470, and the output end of the drive motor 470 is transmission-connected to one end of a screw rod 430, and the distance from the axis line of the shaft rod 251 to the center of the side of the outer set 250 is equal to one quarter of the outer circumference of the gear 252, the receiving plate 130 and the upper seat plate 110 are perpendicular to each other, and the distance from the transverse frame 230 to the bottom surface of the upper seat plate 110 is greater than the length of the outer set 250.

[0047] In the specific implementation, initially, the two magnetic blocks repel the magnet 540. When the surveying and mapping is completed, the drive motor 470 is controlled to start through a signal, and the drive motor 470 drives a screw rod 430 to rotate. Through the setting of the transmission box 460, the two screw rods 430 rotate synchronously. When the screw rod 430 rotates, it drives the internal thread seat 440 to move along the mounting plate 410. The screw rod 430 drives the drive rod 450 to move. The drive rod 450 pushes the shaft rod 251. Through the meshing between the gear 252 and the toothed plate 240, when the shaft rod 251 moves horizontally, the outer set 250 is driven to flip through the gear 252. The distance from the axis line of the shaft rod 251 to the side center of the outer set 250 is The distance is equal to one quarter of the outer circumference of the gear 252. When the gear 252 rotates half a circle, one end of the outer set 250 moves to the original position of the other end, thereby driving the outer set 250 to flip half a circle in situ, so that the magnetic block and the magnet 540 are converted from a repulsive state to an adsorbed state, so that the two magnetic blocks and the magnet 540 are adsorbed together, so that the lower end head 500 and the upper receiving component 200 are switched to a rigid connection, so that when the UAV is transferred, the influence of the swing of the surveying instrument on the posture of the UAV is reduced, and the operation is convenient. When the UAV moves into place and is ready for surveying, the lower end head 500 and the upper receiving component 200 are switched to a flexible connection state again.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
