[0072] Combination Figure 5 In the steps (a1) to (a2) and (b1) to (b2), before the aircraft body 11 takes off, the drive assembly 22 is activated, the drive assembly 22 drives the lead screw 23 to rotate, the lead screw 23 drives the connecting sleeve 24 to retract, the connecting sleeve 24 drives the T-shaped slider 25 and the rotating shaft 26 to move to the left as a whole, and the T-shaped slider 25 slides within the range of the first sliding hole 101;

[0073] On the one hand, the rotating shaft 26 pulls the connecting plate 27 and the mounting base 3 together to retract toward the bottom of the body 11;

[0074] On the other hand, while the mounting base 3 retracts, the rotating shaft 26 drives the gear 28 to roll on the second toothed plate 29 and toward the first toothed plate 212. While the gear 28 is rolling, it drives the mounting base 3 to rotate counterclockwise through the rotating shaft 26 and the connecting plate 27, so as to adjust the use angle of the mounting base 3.

[0075] Combination Figure 6 In (c1) to (c2), while the connecting plate 27 and the mounting base 3 rotate around the T-shaped slider 25, the drive shaft 34 rotates around the surface of the missing disc 35. The drive shaft 34 extends and pushes the L-shaped card plate 33 and the first elastic telescopic member 32 to retract, so that the L-shaped card plate 33 automatically extends within the installation range of the storage frame 31.

[0076] Ultimately, the storage frame 31 can be rotated and automatically locked while it retracts and moves, which facilitates the automatic retraction, angle adjustment, and automatic locking of the camera 4 after installation.

[0079] As the T-shaped slider 25 moves to the left, the connecting plate 27 and the storage frame 31 move to the left and rotate clockwise simultaneously. The gear 28 rolls from the range of the second toothed plate 29 to the range of the first toothed plate 212.

[0085] Please refer to the following: Figures 7 to 8 Based on the survey and evaluation system for land spatial planning provided in the first embodiment of the present invention, the second embodiment of the present invention proposes another survey and evaluation system for land spatial planning. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0086] Specifically, the second embodiment of the present application provides a research and evaluation system for territorial space planning, which is different from the first embodiment in that the driving assembly 22 comprises a connecting frame 221, a first bevel gear 222 and a second bevel gear 223, the connecting frame 221 is fixed on the top of the rotating disc 21, the shaft end of the rotating motor 13 penetrates through the connecting frame 221 and is rotationally connected, the first bevel gear 222 is fixed with the shaft end of the rotating motor 13, one end of the lead screw 23 penetrates through the connecting frame 221 and is rotationally connected, and the second bevel gear 223 is fixed with one end of the lead screw 23; the first bevel gear 222 is meshingly connected with the second bevel gear 223.

[0087] In the embodiment, the rotating disc 21 is in frictional contact with the machine body 11.

[0088] After the camera 4 is installed, the first bevel gear 222 is rotated by the rotating motor 13, the second bevel gear 223 is synchronously rotated, and the lead screw 23 is synchronously rotated, thereby providing a power source for the movement of the T-shaped sliding block 25; after the camera 4 is returned to the normal position, the T-shaped sliding block 25 cannot move, the first bevel gear 222 is locked with the second bevel gear 223, and the rotating motor 13 continues to rotate the rotating disc 21 and the camera 4 as a whole; finally, the camera 4 is retracted and returned to the normal position, the rotating disc 21 is automatically unlocked, and when the rotating motor 13 continues to rotate, the camera 4 can be rotated for rotation adjustment of the shooting direction.

[0089] The rotating motor 13 is used to provide a power source for the rotation adjustment of the lead screw 23, and an independent power source is not needed.

[0090] In combination with Figure 7 and Figure 9 , the machine body 11 is provided with a retraction groove 102, and the research and evaluation system for territorial space planning further comprises a damping mechanism 5, which abuts against the machine body 11 and the rotating disc 21. The damping mechanism 5 is arranged between the rotating disc 21 and the machine body 11, which is used to increase the stability of the rotating disc 21 when it is not rotationally adjusted, and to provide stable support for the rotation adjustment of the lead screw 23.

[0091] In the embodiment, the damping mechanism 5 comprises a second elastic extension piece 51 and a damping plate 52, the second elastic extension piece 51 elastically connects the machine body 11 and the damping plate 52, and the damping plate 52 abuts against the outside of the rotating disc 21. The second elastic extension piece 51 provides elastic support for the installation of the damping plate 52, so that the damping plate 52 can stably abut against the outer surface of the rotating disc 21 and increase the friction.

[0092] In combination withFigure 9 and Figure 10 The damping plate 52 is in an arc structure and is a rubber plate. The arc-shaped rubber plate can be attached to the surface of the rotating disc 21, further increasing the stability of the rotating disc 21 when not rotating, and providing support for the stable rotation of the lead screw 23.

[0093] During the rotation of the lead screw 23, the rotating disc 21 does not rotate.

[0094] The working principle of the investigation and evaluation system for national space planning provided by the embodiment is as follows:

[0095] S1, when it is necessary to correct the installed camera 4, the rotating motor 13 is started, the rotating motor 13 drives the first bevel gear 222 to rotate, the first bevel gear 222 drives the second bevel gear 223 to rotate, the second bevel gear 223 drives the lead screw 23 to rotate, the lead screw 23 is used to control the left movement of the connecting sleeve 24 and the T-shaped sliding block 25, and provides a power source for the contraction, rotation and locking of the storage frame 31 and the camera 4.

[0096] S2, during the rotation of the second bevel gear 223 driven by the first bevel gear 222, the second elastic expansion piece 51 elastically abuts against the damping plate 52, the damping plate 52 stably abuts against the rotating disc 21, so that the T-shaped sliding block 25 does not rotate during the contraction and left movement.

[0097] S3, after the storage frame 31 and the camera 4 are completely contracted and corrected, the T-shaped sliding block 25 and the connecting sleeve 24 cannot move leftward, so that the T-shaped sliding block 25 and the connecting sleeve 24 are locked, and the second bevel gear 223 and the first bevel gear 222 are locked.

[0098] so that the rotating motor 13 drives the connecting frame 221 and the corrected camera 4 to rotate and adjust (the rotation power overcomes the frictional force between the damping plate 52 and the rotating disc 21), for adjusting the shooting direction.

[0099] Similarly, when the camera 4 needs to be disassembled, the first sliding hole 101 and the second sliding hole 211 are aligned in advance, only the rotating disc 21 needs to be controlled to rotate within the range of 0-360° and finally stop at 0° or 360°, the rotating motor 13 is started in reverse, the rotating motor 13 drives the first bevel gear 222 to rotate in reverse, the second bevel gear 223 drives the lead screw 23 to rotate in reverse, the connecting sleeve 24 and the T-shaped sliding block 25 move rightward, the camera 4 automatically rotates to the side of the unmanned aerial vehicle 1 and is automatically unlocked, and a power source is provided for the extension and unlocking of the camera 4.

[0100] The above merely provides the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structure variations made according to the present application, or direct / indirect application in other related technical fields, shall fall within the patent protection scope of the present application.
