Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an unmanned aerial vehicle (UAV) for surveying and mapping. Background Art

[0002] In modern society, drones are developing more and more rapidly and are usually used in surveying and mapping projects. Surveying and mapping is the measurement and mapping of various information such as space, landforms, geological structures, etc., to facilitate personnel surveying and mapping.

[0003] However, existing drones are prone to tilt due to their own influence, which causes deviations in the surveying angle and affects the surveying results.

[0004] In order to solve the above-mentioned defects, in the prior art, a Chinese patent with publication number CN220996788U discloses a surveying and mapping UAV, which is used in combination with a fixing rod, a connecting shaft, a vertical rod, a through hole, an insertion rod, a spring, a rubber sheet, a connector and a magnet sheet. Since the rubber sheets are all in contact with the surface of the insertion rod in the four through holes, in actual use, when the UAV takes off on an inclined ground and is affected by the resonance of the airflow, the vertical rod can initially suppress the resonance force. In this case, the resonance force on the vertical rod can be transmitted to the rubber sheet, and finally buffered by the spring to dissipate the resonance. The stability of the drone during takeoff is ensured, and the fixation of the plug rod is also more convenient. After the plug rod is inserted into the socket, the connector will be magnetically connected to the connecting shaft with the help of a magnet sheet, so that the plug rod is fixed in the socket without loosening. Since a screw hole is provided at the middle end of each plug rod, and four screw holes are provided at the upper end of each through hole, and since the screw holes pass through the socket respectively, through this arrangement, external screws can be passed through the screw holes and the screws can be passed through the screw holes together, so that the plug rod can be further fixed in the socket without loosening, so as to ensure the reliability of suppressing and buffering the resonance suffered by the vertical rod.

[0005] Moreover, in the prior art, a Chinese patent with publication number CN221738136U discloses a surveying and mapping UAV. When the camera body at the bottom of the UAV body is rotated and adjusted, the driving motor is started to drive the driving gear to rotate, and the surface of the driving gear is meshed with the gear ring body, thereby driving the cylinder to rotate. The cylinder will drive the support ring body on the surface to rotate. Since the support ring body is located between the upper limit ring and the lower limit ring, and balls are rollingly installed in the six spherical grooves in the support ring body, the rotation of the cylinder drives the balls to roll between the upper limit ring and the lower limit ring, which makes the drive of the cylinder smoother and reduces friction. At the same time, a fixed cylinder is arranged on the outside to protect the internal structure of the fixed cylinder to a certain extent. The bottom of the cylinder is connected to the camera body through a mounting mechanism to realize the rotation adjustment of the camera body, so as to avoid the camera rotation adjustment being not smooth enough, resulting in a large load on the driver driving the camera rotation, and a large friction during the camera rotation process, which affects the service life of the driver.

[0006] The above-mentioned device uses vertical rods and rubber to reduce the resonance force of the drone during use. However, the vertical rods and rubber in the above-mentioned device reduce the resonance force of the drone. When the drone lands, the bottom is easily subjected to impact vibration, thereby affecting the horizontal angle of the surveying and mapping device. In addition, the disassembly of the fan blades is relatively cumbersome. Therefore, in actual use, when the drone lands, the bottom is easily subjected to impact vibration, thereby affecting the horizontal angle of the surveying and mapping device.
