And function III: and adjusting the gravity center in the X direction. When the center of gravity in the X direction needs to be adjusted, the first locking ring screw 27 of the X direction adjusting screw and the second locking ring screw 32 of the X direction adjusting screw are loosened, then the X direction adjusting hand wheel 19 is rotated, the rotation of the X direction adjusting screw 33 is driven by the rotation of the hand wheel, the rotating force is changed into a horizontal force by the screw nut arranged in the Y direction supporting connecting block 12, the Y direction supporting connecting block 12 is driven to move horizontally, the force is transmitted to the central adjusting platform 11 by the first Y direction supporting connecting rod 29 and the second Y direction supporting connecting rod 31, and finally the central adjusting platform is driven to move in the X direction, so that the center of gravity in the X direction is adjusted. When the adjustment of the center of gravity in the X direction is finished, the adjustment of the center of gravity in the X direction can be finished only by locking the first X-direction adjusting screw rod locking ring screw 27 and the second X-direction adjusting screw rod locking ring screw 32.
And the function is four: and adjusting the gravity center in the Y direction. When the Y-direction center of gravity needs to be adjusted, the first Y-direction adjusting screw locking ring screw 30 and the second Y-direction adjusting screw locking ring screw 34 are loosened, the Y-direction adjusting hand wheel 14 is rotated, the rotation of the hand wheel drives the Y-direction adjusting screw 28 to rotate, the screw nut built in the central adjusting platform 11 is used for converting the rotating force into the horizontal force, and the central adjusting platform 11 is driven to horizontally move in the Y direction, so that the adjustment of the Y-direction center of gravity is realized. When the Y-direction gravity center adjustment is completed, the Y-direction gravity center adjustment can be completed only by locking the first Y-direction adjusting screw locking ring screw 30 and the second Y-direction adjusting screw locking ring screw 34.
And a fifth function: and adjusting the gravity center in the Z direction. When the Z-direction gravity center needs to be adjusted, firstly, a locking ring screw 26 of a Z-direction adjusting screw rod is loosened, then, a Z-direction adjusting hand wheel 2 is rotated, the rotation of the Z-direction adjusting screw rod 7 is driven through the rotation of the hand wheel, the rotating force is changed into horizontal force through a screw nut arranged in a middle-layer supporting connecting block 23, the middle-layer supporting connecting block 23 is driven to move in the Z direction, the force is transmitted to a Y-direction supporting connecting block 12 through a middle-layer supporting connecting rod 9, then, the force is transmitted to a central adjusting platform 11 through a Y-direction supporting connecting rod I29 and a Y-direction supporting connecting rod II 31, and finally, the Z-direction gravity center is driven to move in the. When the adjustment of the center of gravity in the Z direction is completed, the adjustment of the center of gravity in the Z direction can be completed only by locking the locking ring screw 26 of the Z-direction adjusting screw.
In conclusion, this frame can realize that unmanned aerial vehicle carries out the timesharing of many equipment and carries simultaneously, satisfies the detection requirement of different tasks, can also satisfy the range requirement of different tasks through the increase and decrease of battery. And, this frame can also guarantee that unmanned aerial vehicle's focus is in all the time and sets for the within range through X, Y, Z three directions's focus regulatory function to guarantee unmanned aerial vehicle's flight safety and the flexibility of flight.
