The worker can install the device in the deep position of the forest, when in installation, the lower part of the base 1 of the device can be buried in the soil, the base 1 forms a closed track, during the period, a proper gap is needed to be left between the bottom surface and the bottom surface of the roller 4, after the installation is finished, when the area monitoring in the track is carried out, the electric control rotary clutch is triggered to be opened when the motor 17 rotates forwards, so that the upper half section and the lower half section of the rotating shaft 14 rotate synchronously, the worker can use the motor 17 to drive the bevel gear 16 positioned on the left side to rotate, then under the mutual meshing relationship of the two bevel gears 16, the rotating shaft 14 can rotate and drive the transmission gear 10 to rotate, when the transmission gear 10 rotates, the plurality of tooth columns A11 fixedly arranged on the inner wall of the bottom groove 2 drive the movable seat 3 to move circularly along the top surface of the base 1, so as to greatly improve the shooting range of the main body 26 of the aerial camera, and under the sliding fit effect of the sliding ball 12 fixed on the bottom surface of the transmission gear 10 and the spherical groove 31 on the bottom surface of the bottom groove 2, the position of the transmission gear 10 is limited to a position which can be just meshed with the tooth post A11, so as to avoid the problem that the transmission gear 10 is shifted to cause the movable seat 3 to be blocked and unable to move during moving, and meanwhile, the rollers 4 on the two sides of the bottom surface of the movable seat 3 can also be firmly moved along the track of the wheel groove 9 under the guiding action of the two wheel grooves 9, thereby further ensuring that the movable seat 3 can not be shifted or derailed, moreover, the upper end of the axle center 5 rotatably connected with the middle part of the roller 4 is fixedly provided with the sliding block 6, when the movable seat 3 moves to the inflection point of the base 1, the sliding block 6 can be moved towards the inner side of the sliding groove 7 or be extruded by the base 1 to slide outwards under the contraction force of the tension spring 8, so that the position of the roller 4 can be fully adapted to the shape of the inner and outer side wall of the base 1, the turnover stability of the moving seat 3 is enhanced again, on the other hand, when the rotating shaft 14 rotates, the tooth column B18 at the upper end of the rotating shaft 14 drives the round seat 23 to rotate along the round groove 24 through the meshing connection relation with the tooth groove 25 on the outer wall of the round seat 23, and only one tooth column B18 is fixedly arranged at the upper end of the left wall of the rotating shaft 14, so that the rotating shaft 14 only stirs the round seat 23 to rotate by an arc angle equivalent to the size of the included angle of the two tooth grooves 25 every turn, so that the rotating disc 20 synchronously rotates at equal time and equal angle along the rotating matching direction of the rotating column 21 and the rotating groove 22 in the moving process of the moving seat 3, the shooting range which can be shot by the aerial photography instrument main body 26 is ensured to be smooth and stable, the shooting range which can be shot by the aerial photograph instrument main body can be improved, the operation can also stably shoot the environment in the inner area of the closed track, in addition, the weather of rain and snow can not wet the aerial photograph instrument main body 26, the two baffles 30 on the two sides can protect the main body 26 of the aerial photography instrument from the two sides, so that the phenomenon that the movement of the device is blocked or the main body 26 of the aerial photography instrument is damaged due to the fact that the branches growing too high around the supporting column 13 are clamped into the fixed seat 27 is avoided, and the protection effect on the main body 26 of the aerial photography instrument is improved.
When shooting the area outside the track and monitoring the area inside the track, the motor 17 is controlled to rotate reversely, the electrically controlled rotary clutch is triggered to be closed at the moment, so that the upper half section is kept static when the lower half section of the rotating shaft 14 rotates, and the aerial camera main body 26 at the top can automatically follow the position change of the movable seat 3 and change the shooting direction when the movable seat 3 circularly moves on the closed track formed by the base 1.
Therefore, the monitoring angles of the inner area and the outer area of the closed track can be automatically matched through the electric control rotary clutch and the motor rotating in two directions, other power driving mechanisms do not need to be arranged independently, cost is saved, and system reliability is improved.
