Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and in particular relates to a protective device for an unmanned aerial vehicle surveying and mapping instrument. Background Art

[0002] Application No. 202223049879.8 provides a protective device for an unmanned aerial vehicle surveying instrument. By setting a surveying instrument, a protective cover, a compression rod, a limit block, a first spring, a T-shaped slot, a second spring and a force block, a protective cover is installed on the outer surface of the surveying instrument to protect the surveying instrument. By pressing the compression rod, the limit block is driven to compress the first spring, thereby driving the T-shaped slot to move to the left, and the T-shaped slot drives the second spring to compress on the force block, so that it can be quickly disassembled and installed. By setting a drone, a support frame, a telescopic rod, a third spring, a support foot and a rubber plate, when the drone lands, the support frame is driven to move downward inside the telescopic rod, and the support frame then transmits the force to the third spring, which is compressed by the third spring and then transmitted to the support foot. The rubber plate installed under the support foot performs the final buffering.

[0003] Most of the existing UAVs do not need to install a protective cover when using a surveying instrument for surveying, because the protective cover will increase the weight of the UAV and slightly affect the surveying effect of the surveying instrument. However, when a protective cover needs to be installed, a protective cover of suitable size can be selected to protect the surveying instrument. However, this device installs the surveying instrument on the protective cover. When the protective cover is not needed, the surveying instrument will be removed together, resulting in the user having to install the surveying instrument and the UAV. Such back-and-forth disassembly and installation increases the user's workload and working time, and is less practical. Utility Model Content
