Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-2 As shown, a remote sensing mapping drone includes a drone 1. A support frame 11 is symmetrically arranged on the drone 1. A crossbar 12 is arranged on the support frame 11. A propeller 19 is symmetrically arranged on the crossbar 12. A protective ring 17 is symmetrically arranged on the crossbar 12. Multiple ventilation slots 18 arranged in a circular array are opened on the protective ring 17. The propeller 19 is arranged inside the protective ring 17. A connecting rod 16 is fixedly arranged between two protective rings 17.

[0023] Specifically, during use, the drone 1 is taken off. When encountering complex environments, the crossbar 12 on the support frame 11 of the drone 1 increases the strength of the drone 1. At the same time, the protective ring 17 on the crossbar 12 protects the propeller 19. If foreign objects are attached to the protective ring 17, the wind generated by the propeller 19 will blow the foreign objects off the protective ring 17 through the ventilation groove 18, reducing the load on the drone 1. When disassembling, the connecting rod 16 can remove the two protective rings 17 for cleaning.

[0024] In the above solution, the crossbar 12 is supported by the support frame 11 on the drone 1, the propeller 19 on the crossbar 12 supports the drone 1 to take off, the protective ring 17 on the crossbar 12 protects the propeller 19, the multiple ventilation slots 18 on the protective ring 17 allow foreign objects to be blown away when they are attached to the protective ring 17, and the connecting rod 16 allows the entire protective ring 17 to be disassembled for cleaning.

[0025] As a further embodiment provided by this utility model, according to Figure 2 As shown, slots 13 are symmetrically provided on the crossbar 12, and insert rods 14 are movably disposed in the slots 13. Fixing rods 15 are provided on the two insert rods 14.

[0026] Specifically, the crossbar 12 is moved downwards so that the insert rod 14 is inserted into the slot 13, and the connecting rod 16 is fixed on the crossbar 12 to prevent the two protective rings 17 from falling off.

[0027] As a further embodiment provided by this utility model, according to Figure 2 As shown, a support plate 20 is symmetrically arranged at the bottom of the UAV 1, and multiple ventilation holes 21 arranged in a linear array are provided on the support plate 20.

[0028] Specifically, the multiple ventilation slots 18 ensure that the drone 1 does not have excessive air resistance during flight.

[0029] As a further embodiment provided by this utility model, according to Figure 2 As shown, a placement rack 23 is provided between the two support plates 20. A sliding groove 24 is provided on the placement rack 23, and a camera 26 is installed in the sliding groove 24.

[0030] Furthermore, a slider 25 is provided inside the slide groove 24, and multiple placement rods 251 arranged in a linear array are provided on the slider 25. The placement rods 251 are provided with sliding grooves 252.

[0032] Furthermore, a pusher frame 250 is provided inside the slide 24.

[0033] Furthermore, a bearing plate 22 is provided at the bottom of the support plate 20.

[0034] Specifically, the sliding slider 25 drives the placement rod 251 to move, and at the same time, the elastic element 253 in the placement rod 251 pushes the sliding rod 254 to move towards the camera 26. Meanwhile, the slider 25 at the other end of the camera 26 is pushed by the pusher 250, causing the camera 26 to move onto the slider 25 at one end and fix the camera 26 in the slide groove 24.

[0035] Working principle: During use, the sliding slider 25 drives the placement rod 251 to move. At the same time, the elastic element 253 inside the placement rod 251 pushes the sliding rod 254 to move towards the camera 26. Meanwhile, the slider 25 at the other end of the camera 26 is pushed by the push frame 250, causing the camera 26 to move onto the slider 25 at one end and fix the camera 26 in the slide groove 24, allowing the drone 1 to take off. When encountering complex environments, the crossbar 12 on the support frame 11 set on the drone 1 increases the strength of the drone 1. At the same time, the protective ring 17 on the crossbar 12 protects the propeller 19. If foreign objects are attached to the protective ring 17, the wind generated by the propeller 19 will blow the foreign objects off the protective ring 17 through the ventilation groove 18, reducing the load on the drone 1. During disassembly, the connecting rod 16 can remove the two protective rings 17 for cleaning.
