DETAILED DESCRIPTION

[0024] The embodiment of the utility model provides an electronic tower ruler for stereophotogrammetry.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a ruler body 1, a mounting base 2 is rotatably mounted on the ruler body 1, an infrared laser ranging camera 3 is fixedly mounted on the mounting base 2, the infrared laser ranging camera 3 is composed of an infrared camera and a laser rangefinder, and can intuitively obtain distance data, a sliding groove 6 is opened on the top of the mounting base 2, and a gear driving structure is arranged inside the sliding groove 6, an installation groove 4 is opened on the outside of the ruler body 1, an electromagnet 5 and a transmission plate 11 are arranged inside the installation groove 4, and an external hard shell 13, an internal sponge pad 14 and a magnet plate 15 are fixedly connected to the bottom of the transmission plate 11.

[0026] When the utility model is in use: a mounting base 2 is rotatably installed on the outside of the tower ruler body 1, and the infrared laser ranging camera 3 is arranged inside the mounting cavity 16 opened on one side of the mounting base 2. When the infrared laser ranging camera 3 and the mounting base 2 are fixedly installed together, most of the structure is protected by the mounting base 2 inside the mounting cavity 16, thereby reducing the possibility of the infrared laser ranging camera 3 being damaged by external forces. In addition, the infrared laser ranging camera 3 is composed of an infrared camera and a laser rangefinder, which can intuitively obtain distance data and improve the measurement accuracy of the electronic tower ruler composed of the tower ruler body 1, the mounting base 2, the infrared laser ranging camera 3 and other parts. (The image is captured by a camera device as a data measurement support, which is a known technology in the application of the tower ruler. For details, please refer to the utility model of patent application number: 202120650682.6)

[0027] When the orientation angle of the infrared laser ranging camera 3 needs to be adjusted, the forward and reverse motor 9 installed inside the mounting circular groove 10 formed on the tower ruler body 1 can be controlled to work. When the forward and reverse motor 9 fixedly installed on the tower ruler body 1 works, since the output end of the forward and reverse motor 9 is fixedly connected to the transmission gear 8 in the gear drive structure, the forward and reverse motor 9 drives the transmission gear 8 to rotate, and the transmission gear 8 is arranged inside the sliding groove 6 and meshed with the driven gear 7, so the transmission gear 8 drives the meshed driven gear 7 to rotate; the driven gear 7 arranged inside the sliding groove 6 is fixedly connected to the mounting seat 2, so the rotating driven gear 7 drives the mounting seat 2 to rotate, so that the orientation angle of the infrared laser ranging camera 3 inside the mounting seat 2 changes. The staff only needs to control the power-on time of the forward and reverse motor 9 to control the orientation of the infrared laser ranging camera 3.

[0028] And the forward and reverse motor 9 can work forward and reverse to control the forward and reverse rotation of the transmission gear 8, so that the mounting base 2 can be reversed. Therefore, it is only necessary to control the mounting base 2 to rotate 180° in one direction and then reset, and then rotate 180° in the other direction, so that the infrared laser ranging camera 3 can complete the rotation around the tower ruler body 1, reducing the difficulty of the circuit arrangement of the infrared laser ranging camera 3.

[0029] When the control tower ruler body 1 is fixedly connected to the electromagnet 5 for operation, the electromagnet 5 works and is fixed to the tower ruler body 1 through magnetic force, so that the transmission plate 11 is fixed to the tower ruler body 1. At this time, the transmission plate 11 will not rotate synchronously with the mounting seat 2, so the rotating mounting seat 2 can rotate the infrared laser ranging camera 3 to the side of the internal sponge pad 14. The internal sponge pad 14 that can be elastically deformed can wipe the lens of the infrared laser ranging camera 3 exposed inside the mounting cavity 16 to ensure the measurement accuracy of the infrared laser ranging camera 3, and the external hard shell 13 is fixedly connected to the side of the internal sponge pad 14 away from the mounting seat 2. The external hard shell 13 blocks foreign flying birds and stones, and can transport the infrared laser ranging camera 3 to the side of the external hard shell 13 to protect the infrared laser ranging camera 3 that is not in use temporarily, and prevent the infrared laser ranging camera 3 from being damaged by the outside.

[0030] During the time period when the electromagnet 5 is not working, since the mounting frame 12 fixedly connected to the bottom of the transmission plate 11 is slidably connected to the mounting seat 2, although the transmission plate 11 is mounted by the mounting frame 12 and cannot be detached from the mounting seat 2, when the mounting seat 2 rotates, the magnet plate 15 is arranged on the top of the driven gear 7 and is adsorbed and works together with the driven gear 7 through magnetic force, so the transmission plate 11 can be driven by the driven gear 7 to rotate, and the transmission plate 11 can rotate synchronously with the mounting seat 2, thereby preventing the infrared laser ranging camera 3 in use from being blocked by the external hard shell 13.

[0031] When the transmission plate 11 rotates and collides with the output end of the forward and reverse motor 9, the movement trajectory of the transmission plate 11 is limited by the mounting frame 12. The magnet plate 15 fixed to the transmission plate 11 is adsorbed together with the driven gear 7 by magnetic force and is not completely fixed. The relative position between the magnet plate 15 and the driven gear 7 can change. When the transmission plate 11 is limited and cannot move, it will not affect the movement of the driven gear 7.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
