[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-5 As shown, this utility model provides a drone data acquisition device, including a drone body 1 and a sampling camera 2, with a shielding mechanism 3 and a fixing mechanism 4 used in conjunction between the sampling camera 2 and the drone body 1.

[0021] The shielding mechanism 3 includes an L-shaped plate 31, which is fixedly connected to the UAV body 1. A frame 32 is fixedly connected to the inner side of the L-shaped plate 31. A connecting gimbal 21 is fixedly connected to the top of the sampling camera 2, and the top of the connecting gimbal 21 can slide and be inserted into the frame 32. The connecting gimbal 21 can adjust the angle and orientation of the sampling camera 2, which is existing technology and will not be elaborated further here. A motor 33 is fixedly installed on one side of the L-shaped plate 31. The output end of the motor 33 rotates through the L-shaped plate 31 and a gear 34 is fixedly sleeved at its end. Two racks 35 are meshed on the outer side of the gear 34, and a sliding post 36 is fixedly inserted into the rack 35. The sliding post 36 slides on the L-shaped plate 31, and a side rod 37 is fixedly inserted into the end of the rack 35 away from the gear 34. Two sliding grooves 312 are provided, and the sliding column 36 is slidably locked in the sliding grooves 312. The sliding grooves 312 limit and guide the movement of the sliding column 36. A shielding frame 38 is fixedly sleeved on the side rod 37. An insertion hole 313 is provided through the upper end of one side of the shielding frame 38, and the side rod 37 is fixedly inserted into the insertion hole 313. The shielding frame 38 is slidably connected to the insertion frame 32, and the two shielding frames 38 can be movably sleeved on the outside of the sampling camera 2. Symmetrically distributed guide rods 310 are fixedly installed on the insertion frame 32, and the shielding frame 38 is slidably sleeved on the guide rods 310. A guide hole 311 is provided through the upper end of the shielding frame 38, and the guide rod 310 slides through the guide hole 311. The cooperation between the guide rod 310 and the guide hole 311 limits and guides the movement of the shielding frame 38.

[0022] By adopting the above technical solution, when in use, starting the motor 33 drives the gear 34 to rotate, which in turn drives the two racks 35 to move synchronously, and further drives the two side rods 37 to move towards each other, which in turn drives the two shielding frames 38 to move towards each other until the opposite sides of the two shielding frames 38 are tightly fitted together, thereby covering and protecting the sampling camera 2 and preventing collision damage to the sampling camera 2 when it is idle. When the sampling camera 2 is in operation, the motor 33 needs to be started again, which drives the two shielding frames 38 to move away from each other until the distance between the two shielding frames 38 is moved to the maximum.

[0023] The fixing mechanism 4 includes a fixing rod 41, which is slidably inserted into the insertion frame 32. A collar 42 is fixedly sleeved at the end of the fixing rod 41. A sliding hole 39 is opened through one side of the insertion frame 32, and the fixing rod 41 is slidably inserted into the sliding hole 39. A groove 44 for matching is opened on the outer wall of the collar 42, and the grooves 44 are arranged in an array. The grooves 44 can increase friction and facilitate operation. A spring 43 is fixedly installed on one side of the collar 42, and the end of the spring 43 is fixedly connected to the insertion frame 32. A fixing hole 22 is opened on one side of the top of the connecting gimbal 21, and the fixing rod 41 can be slidably inserted into the fixing hole 22.

[0024] By adopting the above technical solution, when in use, pull the collar 42 away from the side of the insertion frame 32, thereby moving the fixing rod 41 and stretching the spring 43. When the distance between the collar 42 and the insertion frame 32 reaches its maximum, stop pulling the collar 42. Then, hold the corresponding sampling camera 2 and insert the top of the corresponding connecting gimbal 21 into the insertion frame 32. Then release the collar 42. At this time, the spring 43 will drive the collar 42 to reset, thereby driving the fixing rod 41 to reset. Then, the end of the fixing rod 41 can be inserted into the corresponding fixing hole 22, which can further facilitate the fixed installation of the corresponding sampling camera 2.

[0025] Working principle: When in use, pull the collar 42 away from the side of the insertion frame 32, which will move the fixing rod 41 and stretch the spring 43. When the gap between the collar 42 and the insertion frame 32 is moved to the maximum, stop pulling the collar 42. Then hold the corresponding sampling camera 2 and insert the top of the corresponding connecting gimbal 21 into the insertion frame 32. Then release the collar 42. At this time, the spring 43 will drive the collar 42 to reset, which will drive the fixing rod 41 to reset. Then the end of the fixing rod 41 can be inserted into the corresponding fixing hole 22, which can further facilitate the fixed installation of the corresponding sampling camera 2.

[0026] Then, the motor 33 is started, which drives the gear 34 to rotate, which in turn drives the two racks 35 to move synchronously, and further drives the two side rods 37 to move towards each other, which in turn drives the two shielding frames 38 to move towards each other until the opposite sides of the two shielding frames 38 are tightly fitted together, thus covering and protecting the sampling camera 2 to prevent collision damage when the sampling camera 2 is idle. When the sampling camera 2 is in operation, the motor 33 needs to be started again, which drives the two shielding frames 38 to move away from each other until the distance between the two shielding frames 38 is moved to the maximum.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
