In order to achieve the purpose, the magnetometer distance adjustable unmanned aerial vehicle magnetic detection device comprises an unmanned aerial vehicle body and a magnetometer, a rigid telescopic rod is arranged between the unmanned aerial vehicle body and the magnetometer and is arranged along the vertical direction, the unmanned aerial vehicle body and the magnetometer are connected through the telescopic rod, the telescopic rod comprises a fixed rod and a sliding rod which are in sliding connection with each other, a wire box is installed on the fixed rod, a rope is wound in the wire box and is connected with the sliding rod, and a height adjusting power device for winding and loosening a driving rope is arranged on the wire box.

Further, height adjustment power device includes the line roller, and the line roller rotates to be connected on the line box, and the line box is worn out to the one end of line roller, and the rope is fixed with first gear around rolling up on the line roller, the one end that the line box was worn out to the line roller, and the outside of line box is fixed with the motor, is fixed with the second gear in the pivot of motor, second gear and first gear engagement.

Further, the slide bar includes the body of rod and stopper, stopper and body of rod integrated into one piece to be in on the perisporium of the body of rod, the rope is connected with the stopper, the body of rod is followed the fixed rod in-process that upwards slides, stopper and fixed rod contact.

Further, the wire box is fixed on the fixed rod through a bolt.

Furthermore, a plurality of clamping holes are formed in the rod body along the axis direction, a bolt is connected to the fixed rod in a threaded mode, and the bolt is screwed and inserted into the clamping holes.

Has the advantages that: the flexible of slide bar is controlled to the rolling of rope in through the line box to the change is at the fixed magnetometer of slide bar bottom and the unmanned aerial vehicle between the pole top decide the distance, avoids unmanned aerial vehicle's the magnetic influence to the magnetometer, because the pole and the slide bar of telescopic link are rigid, so can not take place to change the magnetometer angle at will when surveying. Moreover, because the length of the telescopic rod is adjustable, an unmanned aerial vehicle does not need to be specially selected and matched, and the use is convenient.

Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1, in the magnetic detection device for the unmanned aerial vehicle with the magnetometer 2 having the adjustable distance according to the preferred embodiment of the present invention, a rigid telescopic rod is arranged between an unmanned aerial vehicle body 1 and the magnetometer 2, the telescopic rod is arranged along a vertical direction, the unmanned aerial vehicle body 1 is located at the top of the telescopic rod, and the magnetometer 2 is located at the bottom of the telescopic rod. The telescopic link includes mutual sliding connection's fixed rod 7 and slide bar 6, unmanned aerial vehicle body 1 and fixed rod 7's top fixed connection, magnetometer 2 and slide bar 6 fixed connection.

The fixed rod 7 is provided with a wire box 3 through a bolt 11, and the wire box 3 is internally provided with a height adjusting power device for adjusting the total length between the sliding rod 6 and the fixed rod 7.

Height adjustment power device includes line roller 4, and line roller 4 rotates to be connected inside line box 3, and the book has rope 5 in line box 3, and line box 3 is worn out to one of them end of rope 5 to fix on slide bar 6, line roller 4 can receive and release rope 5 through rotating. The line box 3 is worn out to the one end of line roller 4, and the one end that line roller 4 wore out line box 3 is fixed with first gear 10, and the outside of line box 3 is fixed with motor 8, is fixed with second gear 9 in motor 8's the pivot, and second gear 9 and first gear 10 mesh.

Under the action of the motor 8, the wire roller 4 is driven to rotate, and when the wire roller 4 releases the rope 5, the rope 5 can keep a stretched state under the influence of the gravity of the magnetometer 2.
