Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the functions of the invention easy to understand, the invention is further explained by combining the specific embodiments.

As shown in fig. 1 to 5, the photovoltaic inspection unmanned aerial vehicle comprises an unmanned aerial vehicle body 1, a rotor wing 2, support legs 3, a connecting rod 4, a sling 5, a detector bracket 6, a detector 7 and a motor 8; rotor 2 rotates to be connected on the wing arm of unmanned

aerial vehicle body

1, 3 fixed connection of stabilizer blade are in the bottom of unmanned aerial vehicle body 1, connecting rod 4 passes through connecting piece 40 fixed connection in the bottom of unmanned

aerial vehicle body

1, 6 fixed connection of detection instrument support are in the bottom of connecting rod 4, detection instrument 7 rotates through pivot 70 to be connected in detection instrument support 6, hoist cable 5 is connected between unmanned aerial vehicle body 1 and detection instrument 7. Rotor 2 is equipped with four groups, and 3 symmetries of stabilizer blade are equipped with two sets ofly, and the both ends of connecting rod 4 are equipped with the screw thread, and connecting rod 4 is fixed through threaded connection with connecting piece 40 and detection instrument support 6, consequently can dismantle, still carries the camera on the detection instrument 7, and motor 8 is servo motor, can control just reversing in a flexible way.

Motor 8 fixed connection is in unmanned aerial vehicle body 1, and the key connection has wire winding roller 80 on motor 8's the output shaft, 5 mid portions of hoist cable twine on wire winding roller 80, and the both ends of hoist cable 5 pass the bottom plate 10 of unmanned aerial vehicle body 1 and the fixed connection of detection instrument support 6 is on detection instrument 7.
