[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 - Figure 4This utility model provides an embodiment of an engineering surveying drone with a protective structure, comprising a drone body 1, a connecting rod 2 fixedly connected to the outer wall of the drone body 1, a brushless motor 3 fixedly connected to the outer wall of the connecting rod 2, a rotating propeller 4 fixedly connected to the output end of the brushless motor 3, a first spring 5 fixedly connected inside the drone body 1, a sliding block 8 fixedly connected to one end of the first spring 5, a T-shaped locking block 9 fixedly connected to the lower surface of the sliding block 8, a first groove 6 and a second groove 7 formed on the outer wall of the drone body 1, and the sliding block 8... The outer wall is slidably connected to the inner wall of the first slide groove 6, the outer wall of the T-shaped block 9 is slidably connected to the inner wall of the second slide groove 7, the lower surface of the drone body 1 is attached to a U-shaped protective plate 10, the inner wall of the U-shaped protective plate 10 is provided with a slot 11, the outer wall of the T-shaped block 9 is slidably connected to the inner wall of the slot 11, the outer wall of the U-shaped protective plate 10 is provided with a protective component, the protective component is used to protect the brushless motor 3 and the rotating blade 4; the protective component includes a protective frame 12, one end of the protective frame 12 is fixedly connected to the outer wall of the U-shaped protective plate 10, and the outer wall of the protective frame 12 is fixedly connected to a blade protective cover 13;

[0027] Specifically, the connecting rod 2 is used to connect the brushless motor 3 and provide support and fixation for the brushless motor 3. The first groove 6 opened on the outer wall of the drone body 1 is used to provide space for the sliding block 8 to move. The second groove 7 opened on the outer wall of the drone body 1 is used to provide space for the T-shaped locking block 9 fixedly connected to the lower surface of the sliding block 8 to move and limit its movement. The first spring 5 is used to move and reset the sliding block 8. When the first spring 5 is pressed and slides on the inner wall of the first groove 6 opened on the outer wall of the drone body 1, the first spring 5 is compressed. When the sliding block 8 is no longer pressed, the first spring 5 will rebound and push the sliding block 8 to reset. The reset of the sliding block 8 will drive the T-shaped locking block 9 to slide in the inner wall of the slot 11 opened on the inner wall of the U-shaped protective plate 10, thereby completing the quick installation of the U-shaped protective plate 10. The U-shaped protective plate 10 can fix the protective frame 12. The protective frame 12 and the propeller protective cover 13 form a protective assembly to provide protection for the brushless motor 3 and the rotating propeller 4.

[0028] Reference Figure 1 , Figure 5 and Figure 6 The drone body 1 has a sliding connection of a push block 14 inside, and a rectangular block 15 is fixedly connected to the lower end of the push block 14. The drone body 1 has a sliding connection of a fixing block 21 on its outer wall. An engineering measurement camera 22 is provided on the outer wall of the fixing block 21, and a fixing hole 23 is provided on the inner wall of the fixing block 21.

[0029] Specifically, the push block 14 is used to provide a force point. Pressing the push block 14 can drive the rectangular block 15 to move. The fixed block 21 is used to provide a carrier for the engineering measurement camera 22. The engineering measurement camera 22 is used to analyze the health status and safety of engineering structures such as buildings, bridges, and towers as the drone body 1 takes off.

[0030] Reference Figure 1 , Figure 5 and Figure 6 The outer wall of the rectangular block 15 is slidably connected to the inside of the drone body 1, and a rectangular inclined frame 16 is fixedly connected to the lower surface of the rectangular block 15; a locking post 17 is slidably connected to the inner wall of the rectangular inclined frame 16, a first limiting post 18 is fixedly connected to the inside of the locking post 17, and a second limiting post 19 is fixedly connected to the inside of the locking post 17; the outer wall of the first limiting post 18 is slidably connected to the outer wall of the rectangular inclined frame 16, and the outer wall of the second limiting post 19 is slidably connected to the outer wall of the rectangular inclined frame 16; a second spring 20 is fixedly connected to the lower surface of the rectangular block 15, and the bottom end of the second spring 20 is fixedly connected to the inside of the drone body 1; the outer wall of the locking post 17 is slidably connected to the inner wall of the fixing hole 23.

[0031] Specifically, the rectangular block 15 is used to fix the second spring 20 and the rectangular inclined frame 16 at the same time. The top end of the second spring 20 is fixed to the lower surface of the rectangular block 15, and the bottom end is fixed inside the drone body 1. It can move and reset the rectangular block 15. The first limiting post 18 and the second limiting post 19 fixedly connected inside the locking post 17 are used to pull the locking post 17 to slide on the inner wall of the rectangular inclined frame 16 and move when the rectangular inclined frame 16 moves.

[0032] Working principle: When the propeller guard 13 needs to be quickly installed on the drone, firstly, press the sliding block 8 to make it slide into the inner wall of the first groove 6 opened on the outer wall of the drone body 1. The sliding block 8 will drive the outer wall of the T-shaped locking block 9 to slide into the inner wall of the second groove 7, and cause the first spring 5 to contract under force. At this time, place the upper surface of the U-shaped protective plate 10 into a position that fits against the lower surface of the drone body 1. Then stop pressing the sliding block 8. At this time, the first spring 5 will rebound and push the sliding block 8 to reset. Then, the sliding block 8 will drive the T-shaped locking block 9 to slide into the inner wall of the locking groove 11 opened on the inner wall of the U-shaped protective plate 10, thereby... The propeller guard 13 is quickly installed, providing protection for the brushless motor 3 and rotating propeller 4 during operation. This effectively prevents the rotating propeller 4 from colliding with buildings or other structures. When the engineering measurement camera 22 needs to be installed quickly, simply press the push button 14 to make the push button 14 move the rectangular block 15 downwards inside the drone body 1. This causes the second spring 20 to contract under pressure, and the rectangular inclined frame 16 moves downwards accordingly. The second limiting post 19 and the first limiting post are fixedly connected inside the locking post 17 that slides on the inner wall of the rectangular inclined frame 16. 18. As the rectangular inclined frame 16 moves downward, it slides against the outer walls on both sides of the rectangular inclined frame 16. This causes the rectangular inclined frame 16 to slide against the inner wall of the rectangular inclined frame 16, pulling the locking post 17 inward. This causes the locking post 17 to slide inward inside the drone body 1. At this point, the inner wall of the fixing block 21 can slide along the outer wall of the drone body 1. When the inner wall of the fixing block 21 is in contact with the lower surface of the U-shaped protective plate 10, the pressing block 14 is no longer pressed. At this time, the second spring 20 will reset, pushing the rectangular block 15 upward and causing the rectangular inclined frame 16 to move upward as well. When the locking post 17 is subjected to force and resets, it slides into the inner wall of the fixing hole 23 opened in the inner wall of the fixing block 21, thus fixing the fixing block 21 in place. This completes the rapid installation of the engineering measurement camera 22, thereby achieving the effect of rapid installation of the engineering measurement camera 22, reducing preparation time and measurement intervals, and improving the efficiency of task execution. In actual use, this UAV can not only achieve the effect of rapid installation of the propeller guard 13, effectively preventing the UAV rotating propeller 4 from colliding with buildings or other structures, but also achieve the effect of rapid installation of the engineering measurement camera 22, reducing preparation time and measurement intervals, and improving the efficiency of task execution.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
