DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0030] Embodiment 1

[0031] Reference Figures 1-5 A measuring device, the main body structure of the device includes a mounting plate 1, the bottom of the mounting plate 1 is firmly fixed with a mounting pipe 2. At the bottom of the mounting pipe 2, we install a protection mechanism to protect the internal precision components.

[0032] The protection mechanism is composed of a connecting ring 3 and a transparent protective cover 4. The connecting ring 3 is ingeniously rotatably sleeved at the bottom of the mounting pipe 2, and the transparent protective cover 4, which is in the shape of a hemisphere, is firmly fixed at the bottom of the connecting ring 3. Such design not only provides dust protection for the measuring mechanism below, but also ensures the accuracy of measurement. At the same time, we fix a mounting block 5 at the bottom of one side of the mounting pipe 2, and an arc-shaped scraping rod 6 is installed at the bottom of the mounting block 5, which keeps close contact with the outer side of the transparent protective cover 4. When the connecting ring 3 rotates under the action of the driving mechanism, the transparent protective cover 4 will also rotate, so that the outer side of the transparent protective cover 4 can be in full contact with the arc-shaped scraping rod 6, and the dust falling on it can be cleaned in time, thereby ensuring the shooting effect of the multi-spectrum measurement camera 11.

[0033] The measuring mechanism is mainly composed of a supporting assembly and a multi-spectrum measuring camera 11. The core of the supporting assembly is a supporting column 7 which is rotatably connected at the bottom center of the mounting plate 1. The bottom end of the supporting column 7 is fixed with a connecting frame 8, and the bottom of one side of the connecting frame 8 is mounted with a driving motor 9. The output shaft of the driving motor 9 penetrates into the connecting frame 8 and is fixedly connected with a fixed plate 10, and the multi-spectrum measuring camera 11 is stably mounted on one side of the fixed plate 10. Such a design enables us to easily adjust the shooting direction of the multi-spectrum measuring camera 11 by starting the driving motor 9 to drive the fixed plate 10 and the multi-spectrum measuring camera 11 to move in an arc shape in the longitudinal direction.

[0034] In order to drive the rotation of the protection mechanism, a driving mechanism is installed on the inner wall of one side of the mounting tube 2. The mechanism is mainly composed of a driving motor 12, a driving gear 13 and a transmission gear ring 14. The output shaft of the driving motor 12 is fixedly connected with the driving gear 13, and the transmission gear ring 14 is fixedly installed on the inner side of the connecting ring 3. The driving gear 13 is in close engagement with the transmission gear ring 14, so that when the driving motor 12 is started, the transmission gear ring 14 and the connecting ring 3 can be driven to rotate through the driving gear 13, and then the transparent protective cover 4 is driven to rotate.

[0035] In order to realize the horizontal rotation adjustment of the multi-spectrum measuring camera 11, a connecting mechanism is designed. The mechanism is mainly composed of an L-shaped frame 17, a belt assembly, a rotating shaft 26, a driving shaft 22, a transmission bevel gear 23, a driving bevel gear 21, a connecting bevel gear 24 and a bevel gear ring 16. The L-shaped frame 17 is sleeved on the supporting column 7, and the belt assembly is installed on the top inner wall of the L-shaped frame 17. The belt assembly is composed of a first synchronous pulley 18, a second synchronous pulley 19 and a synchronous belt 20, which are collectively sleeved on the supporting column 7 and connected with the two sliding grooves 15 on the supporting column 7. The bottom end of the rotating shaft 26 is fixedly connected with the driving bevel gear 21, and the bottom inner wall of one side of the L-shaped frame 17 is rotatably connected with the driving shaft 22, and the driving shaft 22 is fixedly sleeved with the transmission bevel gear 23. The driving bevel gear 21 is in close engagement with the transmission bevel gear 23, and one end of the driving shaft 22 is fixedly connected with the connecting bevel gear 24. The top of the transmission gear ring 14 is fixedly installed with the bevel gear ring 16, and the connecting bevel gear 24 is in movable engagement with the bevel gear ring 16.

[0036] When the bevel gear ring 16 rotates with the transmission gear ring 14, the connecting bevel gear 24 will drive the driving shaft 22 to rotate. Then, under the meshing transmission action of the transmission bevel gear 23 and the driving bevel gear 21, the rotating shaft 26 will drive the second synchronous pulley 19 to rotate. At this time, under the transmission cooperation of the synchronous belt 20 and the first synchronous pulley 18, the supporting column 7 will rotate, thereby driving the multi-spectrum measuring camera 11 to rotate in the horizontal direction with the supporting column 7 as the center, and realizing the adjustment of the shooting range.

[0037] In addition, in order to drive the support column 7 to rotate more stably when the first synchronous wheel 18 rotates, two sliding strips are symmetrically and fixedly installed in the first synchronous wheel 18. The sides close to each other of the two sliding strips respectively extend into the corresponding sliding grooves 15 and are in close sliding connection with the inner walls of the sliding grooves 15.

[0038] The application can be used in the field of aerial photography, and can also be used in other fields applicable to the application.

[0039] Embodiment 2

[0040] Reference Figure 3 On the basis of Embodiment 1, a multispectral aerial photogrammetry device is improved and applied to the field of aerial photography. In order to conveniently adjust the meshing state of the connecting bevel gear 24 and the bevel gear ring 16, an electric push rod 25 is fixedly installed on one side of the top of the mounting plate 1. A connecting plate is fixedly connected to the output shaft of the electric push rod 25, and the connecting plate is fixedly installed on one side of the L-shaped frame 17. When it is needed to adjust the horizontal direction rotation of the multispectral measurement camera 11, the electric push rod 25 can be started to drive the L-shaped frame 17 to move longitudinally, so that the connecting bevel gear 24 and the bevel gear ring 16 are kept in meshing. When it is not needed to make such adjustment, the connecting bevel gear 24 can be moved upward to be separated from the bevel gear ring 16, so that the rotation of the transmission gear ring 14 will not drive the multispectral measurement camera 11 to rotate in the horizontal direction.

[0041] However, as known by those skilled in the art, the working principles and wiring methods of the driving motor 9, the multispectral measurement camera 11, the driving motor 12 and the electric push rod 25 are common, which belong to conventional means or common general knowledge, and will not be described here. Those skilled in the art can make any selection or arrangement according to their needs or convenience.

[0042] The above is only a preferred specific embodiment of the application, but the protection scope of the application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered within the protection scope of the application.
