The unmanned aerial vehicle-based automatic power distribution network inspection device according to claim 7, wherein: the sleeve (334) is provided with a through hole (3341) for the movable column (3321) and the outer cylinder (3322) to pass through, and a rubber ring pad (3342) is arranged in the inner cavity of the through hole (3341).
9. The unmanned aerial vehicle-based automatic power distribution network inspection device according to claim 7, wherein: the adjusting piece (34) comprises a stud (341) which is rotatably connected to the center of the top of the lower support plate (32), a movable plate (342) is connected to the surface of the stud (341) in a threaded mode, the surface of the sleeve (334) is fixedly connected with the corresponding movable plate (342), and a knob (343) is fixedly connected to the top end of the stud (341).
10. An inspection method of an automatic inspection device for a power distribution network based on an unmanned aerial vehicle, which adopts the automatic inspection device for the power distribution network based on the unmanned aerial vehicle according to any one of claims 1 to 9, and is characterized by comprising the following steps:
s1, adjusting a pre-pressing value of a spring (331): through rotating knob (343), knob (343) drives double-screw bolt (341) to rotate, under the screw effect, double-screw bolt (341) drives fly leaf (342) along its axial direction upwards or down remove, fly leaf (342) drives sleeve (334) and upwards or down removes in the surface of extensible member (332) in step, because keep off ring (333) and movable column (3321) fixed connection, therefore the top position of spring (331) is unchangeable, and when sleeve (334) reciprocates, can drive the bottom of spring (331) and take place the position change, and then adjust the pre-compaction value of spring (331), make sleeve (334) play the guard action to spring (331) simultaneously still can adjust spring (331);
s2, power grid inspection: positioning is carried out through a sensor on the shell (13), the ground controller is controlled, so that the power grid can accurately fly around, then shooting is carried out through the camera (14), an image is transmitted to a terminal on the ground, and accurate positioning shooting of power grid inspection is realized;
s3, landing: when the unmanned aerial vehicle body (1) is patrolled and examined and flies to falling the drop point, the ground wheel (22) contacts with the ground, the weight of the unmanned aerial vehicle body (1) is patrolled and examined and the gravitational potential energy that carries is compressed to damper (3), go up extension board (31) and move towards the direction of extension board (32), go up extension board (31) and drive movable column (3321) and slide in the inner chamber of urceolus (3322), movable column (3321) still drives baffle ring (333) synchronous movement for spring (331) atress shrink, and then the elastic force of usable spring (331) is to patrolling and examining unmanned aerial vehicle body (1) buffering, ensures to patrol and examine unmanned aerial vehicle body (1) and descend smoothly.
