The unloading method based on a drone photovoltaic panel transport device as described in claim 4, characterized in that: The formula for calculating the maximum weight that the drone can carry is as follows: P is the maximum weight that the UAV (1) can carry, and F is the rope tension value, which includes the rope tension values ​​of the fourth rope (6) and the fifth rope (7). a F is the tension in the fifth rope (7). b The tension of the fourth rope (6) is calculated, and the rope diameter value includes the diameters of the fourth rope (6) and the fifth rope (7).

6. The unloading method based on a drone-based photovoltaic panel transport device as described in claim 5, characterized in that, The calculation method for the tension of the fifth rope (7) is as follows: The calculation method for the tension of the fourth rope (6) is as follows: N is the number of photovoltaic panels (12), W a W is the weight of a single photovoltaic panel (12). b For the net weight of the photovoltaic panel mounting device, F c To unload the self-weight of structure (9), θ is the angle between the two fourth ropes (6). The formula for calculating the rope diameter is: σ max The maximum tensile stress of the rope is the value on the rope nameplate; D is the rope diameter in mm. This formula is applicable to the calculation of the diameter of the fourth rope (6) and the fifth rope (7).
