The shooting unit is fixed on the flip-up connecting part; When the drone hovers, the protective base tilts downwards via the flip-connection to carry the shooting unit inside the accommodating cavity to a position below each landing gear; or, during non-shooting periods, the protective base tilts upwards via the flip-connection to carry the shooting unit into the accommodating cavity.

2. The image acquisition device based on BIM smart construction site technology according to claim 1, wherein, The mounting base includes: A fixing base is detachably connected to the connecting platform; the fixing base has an inner cavity, and the bottom of the fixing base has an opening communicating with the inner cavity; the inner cavity is provided with a fixing cylinder surrounding the opening; A thrust bearing has an inner ring and an outer ring, the outer ring being interference-fitted with the fixed cylinder; one end of the inner ring extends out of the opening and is connected to a fixed disc, the fixed disc being the rotating connecting part; A drive structure is mounted on the fixed base and connected to the other end of the inner ring, used to drive the inner ring and the fixed disk to rotate.

3. The image acquisition device based on BIM smart construction site technology according to claim 2, wherein, The inner diameter of the fixed cylinder is larger than the diameter of the opening.

4. The image acquisition device based on BIM smart construction site technology according to claim 2, wherein, The driving structure includes: The first gear is located in the inner cavity and is fixedly connected to the end of the inner ring; The second gear is located in the inner cavity and meshes with the first gear; The first servo motor is fixed on the fixed base, and its power end is connected to the second gear.

5. The image acquisition device based on BIM smart construction site technology according to claim 2, wherein, The protective base includes: There are two vertical support plates, both of which are fixed on the fixed plate and are spaced apart along the interval direction of the two landing gears; each vertical support plate has a corresponding first vertical side, a second vertical side and a bottom side; A flip-up tray is rotatably connected at one end to the two vertical uprights; the pivot shaft of the flip-up tray is located at the intersection of the downward extension line of the first vertical side and the bottom side, and the axis is set along the interval direction between the two rises and falls; the flip-up tray is the rotatable connecting part. The second servo motor is fixed on one of the vertical plates, and its power end is connected to the adapter shaft. When the flip tray tilts upward to contact the second vertical side and the bottom side, it moves the shooting unit between the two vertical plates; when the flip tray tilts downward, it carries the shooting unit to a position below each landing gear.

6. The BIM-based smart construction site technology image acquisition apparatus of claim 5, wherein, The vertical plate also includes an auxiliary baffle, which is located at the first vertical side and connected to the two vertical plates. The cavity is formed by the two vertical plates, the auxiliary baffle, and the tilting tray that rotates upward to its limit position.

7. The BIM-based smart construction site technology image acquisition apparatus of claim 6, wherein, The inner wall of the auxiliary baffle is provided with a sponge pad that can elastically abut against the shooting unit.

8. The BIM-based smart construction site technology image acquisition apparatus of claim 5, wherein, The flip-over tray includes: The first flat plate is rotatably connected with the two vertical standing plates through the adapter shaft at one end; The second flat plate is fixedly connected with the other end of the first flat plate and is arranged perpendicularly to the first flat plate; the second flat plate is used for fixedly connecting the shooting unit.
