[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 3 , a special anti-collision device for drone oblique photography, including a body 5, a wing 1, and a protective shell 7. The top of the protective shell 7 is fixed with a mounting shell 3 by bolts, and a mounting rod 12 is fixed to the inner wall of one side of the mounting shell 3 by bolts. Two first springs 11 are welded to the top of the mounting rod 12, and one end of the two first springs 11 is welded to a connecting plate 10, and the connecting plate 10 slides with the mounting shell 3. The bottom of the protective shell 7 is fixed with two mounting cylinders 8 by bolts. The top inner walls of the two mounting cylinders 8 are fixed with threaded rods 14 by bolts. The circumferential outer walls of the two threaded rods 14 are threadedly connected with nuts 15. The bottoms of the nuts 15 are welded with second springs 13. One end of the second spring 13 is fixed with a connecting rod 16 by bolts, and the connecting rod 16 slides with the mounting cylinder 8. The bonding limit ring 17 of the mounting cylinder 8 is fixed to the bottom of the two connecting rods 16 with the support plate 6 by bolts. If the top of the body 5 collides, The connecting plate 10 moves downward and compresses the first spring 11. The first spring 11 uses its own spring elasticity. The first spring 11 can absorb and store the energy brought by the impact force, thereby protecting the top of the body 5. When the drone falls, the support plate 6 contacts the ground, thereby applying an impact force to the connecting rod 16. The connecting rod 16 moves upward, thereby squeezing the second spring 13. The second spring 13 can absorb and store the energy applied by the impact force, thereby achieving protection for the body 5 during landing and flight, and improving the service life of the drone. If it is necessary to replace drones of different sizes or different working conditions, the operator can turn the nut 15. Under the action of the threaded rod 14, the nut 15 moves up and down. At this time, the limit ring 17 limits the connecting rod 16, changes the length of the second spring 13, and thereby adjusts the preload force of the second spring 13, thereby ensuring the stability and resilience of the second spring 13.

[0022] Two protective rings 4 are fixed on both sides of the protective shell 7 by bolts, and the two protective rings 4 are symmetrically distributed. The protective ring 4 can effectively protect the wing 1, preventing the wing 1 from colliding during flight and causing the flight control to be impacted, thereby causing damage to the wing 1, thereby improving the service life of the wing 1. One side of the multiple protective rings 4 is bonded with a rubber sleeve 9, which has a shock-absorbing and buffering effect, and can further improve the protective effect of the protective ring 4. The bottom of the support plate 6 is provided with multiple anti-skid grooves, and the multiple anti-skid grooves are evenly distributed. The anti-skid grooves can improve the circumferential outer wall of the nut 15 is provided with multiple anti-skid patterns, and the multiple anti-skid patterns are evenly distributed. The anti-skid patterns can improve the friction of the nut 15 when used, making the nut 15 more convenient to use. A baffle 2 is fixed on one side of the protective shell 7 by bolts. The baffle 2 can protect the camera of the drone and block rain to prevent rain from blocking the camera when it rains, thereby affecting the shooting quality.

[0023] Working principle: During the flight of the drone, the protection ring 4 can effectively protect the wing 1. If the top of the body 5 is hit, the connecting plate 10 moves downward and compresses the first spring 11. The first spring 11 uses its own spring elasticity to absorb the impact force. When the drone falls, the support plate 6 contacts the ground, thereby applying an impact force to the connecting rod 16. The connecting rod 16 moves upward, thereby squeezing the second spring 13. The second spring 13 uses its own spring elasticity to absorb the impact force. The operator can turn the nut 15. Under the action of the threaded rod 14, the nut 15 moves up and down. Under the action of the nut 15 and the limit ring 17, the preload force of the second spring 13 is adjusted to suit drones of different weights or different working conditions.

[0024] In addition, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
