DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in 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.

[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6The utility model provides a technical solution: a high-precision aerial survey and remote sensing data acquisition device, including an unmanned aerial vehicle 1 and a rotating head 2 installed at the bottom of the unmanned aerial vehicle 1, and a connecting head 3 rotatably connected to the surface of the rotating head 2, the purpose of which is to facilitate the subsequent installation of the connecting arm 4 to rotate, so as to facilitate the camera 7 to take all-round pictures during the data collection process. The connecting arm 4 is plugged into the side of the connecting arm 3 away from the rotating head 2, and the camera 7 is installed at the bottom end of the connecting arm 4 for aerial shooting and data collection. The lens component 8 is threadedly connected to the camera end of the camera 7, the groove 802 is opened on the inner wall of the lens component 8, and the heating wire 803 is installed in the groove body of the groove 802. There are two grooves 802 and two heating wires 803, the purpose of which is to improve the efficiency of heating the lens 804. A lens 804 is fixedly mounted inside the lens assembly 8 and is in contact with the heating wire 803. The purpose of the contact between the lens 804 and the heating wire 803 is to facilitate faster heat transfer from the heating wire 803 to the surface of the lens 804, thereby quickly defogging. A connection hole 805 is provided on the housing surface of the lens assembly 8. The power supply assembly 5 is mounted on the arm body of the connecting arm 4. A wire 6 is connected between the power supply assembly 5 and the heating wire 803 via the connection hole 805. A thread 801 is provided on one end surface of the lens assembly 8 to facilitate installation and connection between the lens assembly 8 and the camera 7. A locking assembly is provided between the connector 3 and the connecting arm 4.

[0024] A plug 401 is welded to one end of the connecting arm 4, near the connector 3. Two locking holes 402 are defined on the surface of the plug 401. The locking assembly includes a slot 301 defined in a side wall of the connector 3. The slot 301 and the plug 401 fit together to facilitate insertion of the plug 401 into the slot 301. A U-shaped cavity 302 and a cavity 304 are defined within the connector 3. A locking member 303 is disposed within the U-shaped cavity 302. The end of the locking member 303 fits into the locking hole 402, allowing the end of the locking member 303 to be inserted into the locking hole 402, thereby securing the connecting arm 4 in position. Connecting rods 305 are installed in the front and rear cavities of the cavity 304. The top rod body of the connecting rod 305 movably passes through the wall of the cavity 304 and is fixedly connected to the bottom end of the locking piece 303. The bottom rod body of the connecting rod 305 movably passes through the bottom wall of the cavity 304. A reset plate 307 is provided in the cavity 304. The two ends of the reset plate 307 are fixedly sleeved on the rod surface of the two connecting rods 305 respectively. A spring 306 is provided in the cavity 304 and is sleeved on the surface of the connecting rod 305. The spring 306 is provided on the side of the reset plate 307 close to the locking piece 303. Its purpose is to facilitate the reset plate 307 to drive the connecting rod 305 to automatically reset under the action of the spring 306 when the handle 308 is released. A handle 308 is provided at the bottom of the connector 3 , and both ends of the handle 308 are respectively connected to the ends of the two connecting rods 305 , so as to facilitate pushing the connecting rods 305 to move.

[0025] The heating wire 803 is energized through the power supply assembly 5 and the wire 6, causing it to heat up, thereby achieving the effect of heating the lens 804, thereby avoiding the occurrence of water mist on the lens 804 due to the large temperature difference when working at high altitudes, which is beneficial to improving the accuracy of data collection. When the connecting arm 4 needs to be removed from the drone 1, it is only necessary to push the connecting rod 305 upward through the handle 308. During the upward movement of the connecting rod 305, it will drive the reset plate 307 to squeeze the spring 306, and at the same time drive the locking member 303 to move upward, so that the end of the locking member 303 is pulled out from the locking hole 402 of the plug 401, and then the connecting arm 4 can be disassembled. This is very convenient and facilitates the subsequent maintenance and repair of the camera 7. When it needs to be reinstalled, just push the handle 308 again, which is easy to operate.
