Description

Technical Field

[0001] The utility model relates to the field of forestry surveying and mapping, in particular to a forestry surveying and mapping UAV device. Background Art

[0002] The existing patent (publication number: CN218806639U) proposes a forestry surveying and mapping UAV device. Four support blocks are fixedly connected to the outer surface of one side of the fuselage. Connecting blocks are fixedly arranged between the inner surfaces on both sides of the four support blocks. One end of each of the four connecting blocks away from the support block is fixedly connected to a support seat. Connecting rods are fixedly arranged on the top surfaces of the four support seats. One end of each of the four connecting rods away from the support seat is fixedly connected to a fan blade. However, in the process of forestry surveying and mapping, the flight environment is relatively complex. The completely exposed fan blades are more likely to be interfered by external sundries, affecting flight safety. Summary of the Invention

[0003] In view of the above deficiencies in the prior art, the utility model provides a forestry surveying and mapping UAV device. The propeller is protected by a propeller protection shell covering the outside of the propeller, avoiding damage to the propeller by sundries during forestry surveying of the UAV. The protection crankshaft on the top of the propeller protection shell has a curved structure and is arranged in an annular array. When the propeller protection shell is collided, the propeller protection shell itself and the protection crankshaft array group can undergo a certain amount of elastic deformation, buffering the impact of the collision object to a certain extent and increasing the safety of this device during forestry surveying operations.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A forestry surveying and mapping UAV device includes a UAV main body, a propeller protection shell, a protection shell mounting platform, mounting platform connecting screws, protection shell positioning screws, protection shell positioning pressing blocks, and buffer springs. The side of the UAV main body has propeller mounting arms. The surface of the propeller mounting arms has lower screw mounting holes. The end of the propeller mounting arms has propellers. A protection shell mounting platform is arranged above the propeller mounting arms. The inside of the protection shell mounting platform has a protection shell mounting groove. The bottom of the protection shell mounting platform has a mounting platform connecting seat. The middle of the mounting platform connecting seat has an upper screw connection hole. The mounting platform connecting screws pass through the upper screw connection holes and are threadedly connected to the lower screw mounting holes. The nuts of the mounting platform connecting screws press on the upper part of the mounting platform connecting seat. The protection shell mounting platform coincides with the propeller axis. The propeller protection shell covers the outside of the propeller. The top of the propeller protection shell has a protection crankshaft, and a chamfer is provided at the top of the protection crankshaft.

[0006] The side surface of the propeller protective shell has side hollow grooves, and multiple groups of side hollow grooves are evenly arranged around the propeller protective shell. The propeller protective shell is inserted into the protective shell installation groove. The inner side of the protective shell installation groove has a longitudinal positioning platform, and the propeller protective shell has a longitudinal positioning groove inside. The longitudinal positioning groove is adapted to the longitudinal positioning platform. The longitudinal positioning groove is connected to the longitudinal positioning platform, and the longitudinal positioning groove sleeves the outside of the longitudinal positioning platform. The side surface of the protective shell installation platform has protective shell positioning screw holes.

[0007] The three groups of protective shell positioning screw holes are evenly arranged on the surface of the protective shell installation platform. The protective shell positioning screw holes are threadedly connected with the protective shell positioning screws. The protective shell positioning screws have longitudinal positioning grooves inside. The longitudinal positioning grooves are adapted to the protective shell positioning pressing blocks. The longitudinal positioning grooves are connected to the protective shell positioning pressing blocks, and the protective shell positioning pressing blocks slide inside the longitudinal positioning grooves.

[0008] Beneficial effects: 1. The present utility model protects the propeller by covering the propeller with the propeller protective shell, avoiding damage to the propeller by debris interference during forestry survey of the unmanned aerial vehicle. The protective crankshaft on the top of the propeller protective shell has a curved structure and is arranged in a circular array, enabling the propeller protective shell itself and the protective crankshaft array group to undergo a certain amount of elastic deformation when being collided, buffering the impact of the collision object to a certain extent, and increasing the safety of this device during forestry survey operations.

[0009] 2. The protective crankshaft of the present utility model is a thin column structure, ensuring the ventilation of the propeller protective shell itself. At the same time, a chamfer is provided at the top of the protective crankshaft, and the chamfer can better divide the flowing air, reducing the degree of air flow disorder when passing through the propeller protective shell, and ensuring the smoother flight of this unmanned aerial vehicle.

[0010] 3. One side of the buffer spring of the present utility model is fixedly connected to the protective shell positioning pressing block, and the other side is fixedly connected to the inside of the longitudinal positioning groove. By pressing the protective shell positioning pressing block against the side surface of the propeller protective shell, the buffer spring can contract when the propeller protective shell is impacted, further buffering the impact received by the propeller protective shell, and further increasing the protection of the propeller protective shell.

[0011] 4. The longitudinal positioning groove of the present utility model sleeves the outside of the longitudinal positioning platform. After the propeller protective shell is positioned by the protective shell positioning pressing block, the propeller protective shell is completely positioned in the longitudinal direction, preventing the propeller protective shell from falling off during flight, ensuring the convenience of the installation and disassembly process of the propeller protective shell while ensuring the stability of the installation of the propeller protective shell.
