A drone for natural resource law enforcement

Abstract

The utility model discloses a drone for natural resource law enforcement, including: a drone body, an outer cover, an active turntable, a bracket, a follower turntable, a threaded rod, a pull rod, and an adjustment frame. The utility model, by designing the structure of the active turntable and the follower turntable, directly drives the bracket, the first connecting rod, and the camera body to rotate by the rotation of the active turntable, so as to be suitable for 360° all-round acquisition of images, and relies on the follower turntable to drive the threaded sleeve to move the threaded rod up and down, thereby driving the pull rod and the adjustment frame to adjust the top-down angle of the camera body, so as to adjust to a suitable shooting angle when the drone is flying in a high-low hole. The entire solution uses only one integrated motor, which reduces the weight of the drone and makes it more flexible.

Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle inspection, and in particular to a unmanned aerial vehicle for natural resource law enforcement. Background Art

[0002] Sustainable development is the common goal of all countries in the world. Protecting natural resources and combating illegal activities are crucial to achieving sustainable development.

[0003] As a common aerial inspection tool, drones have been widely used in the field of natural resource law enforcement. However, during the monitoring process, due to the limitations of the camera's own acquisition range, it is necessary to adjust the camera's angle and height position in order to obtain more comprehensive image information. Generally, two motors are required to cooperate (up and down angle and autorotation cruise detection), which increases the drone's own weight and reduces the cruise time. For this reason, the utility model provides a new type of drone for natural resource law enforcement. Summary of the invention

[0004] In order to solve the above shortcomings and deficiencies of the prior art, the purpose of the utility model is to provide a drone for natural resource law enforcement.

[0005] The technical solution of the utility model is:

[0031] The utility model is further introduced below in conjunction with the accompanying drawings and specific embodiments:

[0032] refer to Figures 1 to 5 A UAV for natural resource law enforcement includes: a UAV body 1, an outer cover 2, an active turntable 4, a bracket 9, a follower turntable 6, a threaded rod 8, a pull rod 12, and an adjustment frame 17.

[0033] A support member 3 is fixedly installed at the bottom of the drone body 1, which is used to support the drone body 1 when the drone body 1 lands. The outer cover 2 is fixedly installed at the bottom of the drone body 1, and the bottom of the outer cover 2 is higher than the bottom end of the support member 3 to prevent the bottom of the outer cover 2 from hitting the ground when the drone body 1 lands. The active turntable 4 is rotatably installed on the inner side of the outer cover 2, and is driven to rotate by a driving component arranged inside the outer cover 2. Specifically, the active turntable 4 and the outer cover 2 can be integrated into a motor component with the active turntable 4 as the rotor and the outer cover 2 as the stator. A coil is arranged on the outer side of the active turntable 4 and a magnetic sheet is arranged on the inner side of the outer cover 2, forming a motor component with the active turntable 4 as the rotor and the outer cover 2 as the stator.

[0034] The bracket 9 is fixedly mounted on the bottom end of the active turntable 4 , a first connecting rod 11 is movably mounted on the bracket 9 , and the middle portion of the first connecting rod 11 is connected to the bracket 9 , and a first end of the first connecting rod 11 is fixedly connected to the camera body 10 .

[0035] By rotating the active turntable 4, the bracket 9 and the first connecting rod 11 are directly driven to rotate, thereby driving the camera body 10 to rotate, thereby achieving 360° image acquisition.

[0036] The follower turntable 6 is rotatably mounted on the top of the driving turntable 4, and an arc-shaped slideway hole is opened on the end surface of the follower turntable 6. A transmission column 5 is fixedly connected to the top of the driving turntable 4 and inside the arc-shaped slideway hole.

[0037] When the active turntable 4 rotates, it drives the transmission column 5 to rotate. The transmission column 5 slides inside the arc-shaped slide hole. At this time, it will not drive the follower turntable 6 to rotate. However, if the transmission column 5 is against one end of the arc-shaped slide hole, the follower turntable 6 can rotate along with the active turntable 4.

[0038] A polygonal guide hole is provided at the top of the threaded rod 8, and a guide rod is fixedly connected to the bottom of the drone body 1 and located on the inner side of the polygonal guide hole. A threaded sleeve 7 is threadedly connected to the outer side of the threaded rod 8, and the outer ring of the threaded sleeve 7 is installed with an interference fit with the center hole of the follower turntable 6. The top of the pull rod 12 is rotatably installed with the bottom end of the threaded rod 8, and the bottom end of the pull rod 12 has a ball seat. The top of the adjustment frame 17 is spherical, and the top of the adjustment frame 17 is movably installed on the inner side of the ball seat. The adjustment frame 17 is movably connected to the first end of the first connecting rod 11.

[0039] When in use, the active turntable 4 rotates to directly drive the bracket 9 and the first connecting rod 11 to rotate, and then drive the camera body 10 to rotate, controlling the active turntable 4 to rotate back and forth, that is, the transmission column 5 will not abut against one end of the arc-shaped slide hole, and will not drive the follower turntable 6 to rotate.

[0040] When the flight altitude of the UAV body 1 changes, the active turntable 4 is driven to rotate. After the transmission column 5 abuts against one end of the arc-shaped slide hole, the active turntable 4 is continued to be driven to rotate, thereby driving the follower turntable 6 to rotate, so that the threaded sleeve 7 rotates. The threaded sleeve 7 and the threaded rod 8 are threadedly matched. When relative rotation occurs, the threaded rod 8 is synchronously driven to move up and down, pushing the adjustment frame 17, and then driving the first end of the first connecting rod 11 to move up and down. The first connecting rod 11 rotates, and the top-view angle of the camera body 10 is adjusted.

[0041] In one embodiment, it further comprises: a bottom cover 13, the top of the bottom cover 13 is fixedly connected to a suspension rod 15, the top of the suspension rod 15 is fixedly connected to a connecting seat 16, and the connecting seat 16 is movably installed on the outer side of the ball seat.

[0042] A notch 14 is formed on the bottom cover 13 at a position corresponding to the camera body 10 .

[0043] The bottom cover 13 is used to block the bottom port of the outer cover 2 to prevent debris from entering the outer cover 2 .

[0044] In one embodiment, two brackets 9 and two first connecting rods 11 are provided, the adjustment frame 17 is in an inverted "U" shape, and the two first connecting rods 11 correspond to two installation positions, one of which is used to install the camera body 10 and the other is used as a spare.

[0045] In one embodiment, the central angle corresponding to the arc-shaped slide hole is 340°-355°.

[0046] The sum of the illumination angle of the camera body 10 and the central angle corresponding to the arc-shaped slide hole is greater than 360°, so that the camera body 10 can acquire images at 360°.

[0047] In one embodiment, an elastic pressure plate is fixedly connected to the inner wall of the outer cover 2, and the elastic pressure plate abuts against the outer side of the follower turntable 6, so that the follower turntable 6 is not easy to rotate freely, thereby preventing the follower turntable 6 from rotating when the position of the drone body 1 changes, and preventing the active turntable 4 from driving the follower turntable 6 to rotate by contact friction.

[0048] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
