The invention relates to the technical field of engineering surveying and mapping, and provides an engineering surveying and mapping unmanned aerial vehicle which comprises a shell assembly and a surveying and mapping camera, a plurality of mounting bases are arranged on the side edge of the shell assembly, a connecting arm is slidably inserted into the inner side of each mounting base, and the connecting arms are jointly connected with a control mechanism; the end, away from the control mechanism, of the connecting arm is rotationally connected with a turning swing arm which is fixedly provided with a propeller. A containing cavity is formed in the outer surface of the shell assembly, and after the control mechanism drives the connecting arms to move inwards, the turning and swinging arms and the propellers can be turned over and contained in the containing cavity. A guide sleeve is movably arranged between the connecting arm and the turning and swinging arm in a sleeved mode, and after the control mechanism drives the connecting arm to move outwards, the guide sleeve is located on the outer side of the hinged position of the connecting arm and the turning and swinging arm. On the basis, the propeller is contained in the inner side of the shell assembly, the possibility that the propeller accidentally touches an external object can be reduced, and it is ensured that the precision of a plotted and shot image is good.
本申请涉及工程测绘技术领域,提供了一种工程测绘无人机,包括壳体总成和测绘相机,壳体总成的侧边缘布设有多个安装基座,每一安装基座内侧均滑移插设有连接臂,各个连接臂共同连接有操纵机构;连接臂远离操纵机构的一端转动连接有翻摆臂,翻摆臂固定有螺旋桨;壳体总成的外表面设有容纳腔室,当操纵机构带动连接臂向内移动之后,翻摆臂和螺旋桨能够翻转并收纳于容纳腔室内;连接臂与翻摆臂之间活动套设有导向套,当操纵机构带动连接臂向外移动之后,导向套位于连接臂与翻摆臂铰接位置的外侧。基于此,通过将螺旋桨收纳于壳体总成内侧,能够降低螺旋桨意外碰触到外部物体的可能,确保测绘拍摄的图像精度良好。
