[0009] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0010] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0011] Example 1

[0012] See also Figure 1 As shown, a terrain survey drone for construction engineering involved in this embodiment includes a drone frame 1, a camera 2 and a ring-shaped support foot 3 surrounding the camera 2 are provided at the bottom of the drone frame 1, four sets of fan-wing assemblies 4 are arranged around the side of the drone frame 1, and the interval angles between two adjacent fan-wing assemblies 4 are equal. The fan-wing assembly 4 is hinged on the drone frame 1, and a torsion spring (not shown) that is unfolded in a natural state is provided at the hinge between the fan-wing assembly 4 and the drone frame 1. A block 5 for limiting the unlimited upward lifting of the fan-wing assembly is provided on the drone frame 1, and a fan blade 41, a motor 42 and a motor mounting seat 43 are provided on the fan-wing assembly 4. A metal insert 6 with ferromagnetism is provided on the motor mounting seat 43, and a positioning truncated table 7 is provided inside the drone frame 1. The side of the positioning truncated table 7 is arranged with positioning holes 8 that match the fan-wing assembly 4 one by one and are provided for inserting a corresponding metal insert 6, and a magnet (not shown) for adsorbing the metal insert 6 is buried on the hole wall of the positioning hole 8.

[0013] In this embodiment, first, the metal insert 6 is separated from the positioning hole 8, at which time, under the elastic force provided by the torsion spring, the wing assembly 4 is lifted up to unfold. When the wing assembly 4 needs to be stored, downward pressure can be applied to it to close the wing assembly 4 until the metal insert 6 is inserted into the positioning hole 8, and the magnet on the hole wall of the positioning hole 8 adsorbs and fixes the metal insert 6.

[0014] If the wing assembly 4 needs to be unfolded again, the metal insert 6 and the positioning hole 8 can be separated by a slight pulling force.

[0015] Among them, by setting the stopper 5, the fan wing assembly is restricted from being lifted up infinitely, thus playing a limiting role.

[0016] The utility model relates to a terrain survey drone for construction engineering, and the wing assembly on the survey drone can be folded and stored, and the metal inserts on the wing assembly in the stored state are adsorbed and fixed by the positioning holes, so that the volume in the folded and stored state is greatly reduced, which is convenient for transportation and occupies little space; if the wing assembly on it needs to be unfolded, it can be done by slightly exerting force to separate the metal inserts and the positioning holes, and the overall function is complete and practical.
