Detailed Implementation

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: an unmanned aerial vehicle (UAV) oblique photogrammetry device for earthwork engineering surveying, including a body 1, four wings 2 fixedly connected to the upper surface of the body 1, a mounting ring 3 fixedly connected to the lower surface of the body 1, a camera 4 mounted on the surface of the mounting ring 3, a protective device 5 provided on the side of the body 1 near the wings 2, and a control device 6 provided on the upper surface of the body 1.

[0031] The specific setup and function of its protective device 5 and control device 6 will be described in detail below.

[0032] Reference Figures 1-4 As shown in this embodiment: the protective device 5 includes a protective ring 52, which is installed on the upper surface of the fuselage 1. Four grooves are formed on the lower surface of the protective ring 52. Sliding blocks 58 are slidably connected to the surfaces of the four grooves on the protective ring 52. A U-shaped rod 53 is fixedly connected to the lower surface of the sliding block 58. A damper 59 is fixedly connected to the side of the sliding block 58, and the other end of the damper 59 is fixedly connected to the protective ring 52. By setting the protective ring 52, the fuselage 1 can be protected while the U-shaped rod 53 can be connected to the fuselage 1. By setting the sliding block 58, damper 59, and U-shaped rod 53, damage to the wing 2 can be minimized in the event of a collision with the fuselage 1. Four square tubes 54 are fixedly connected to the upper surface of the fuselage 1. Connecting plates 51 are slidably connected to the inner walls of the four square tubes 54, and the connecting plates 51 are fixedly connected to the protective ring 52. By setting up the square tube 54 and the connecting plate 51, the protective ring 52 can be easily connected to the body 1 or removed from the body 1.

[0033] Each of the four square tubes 54 has a connecting rod 55 slidably connected to its inner wall. The connecting rod 55 is slidably connected to the inner wall of the connecting plate 51, and a pull plate 56 is fixedly connected to the end of the connecting rod 55 furthest from the square tube 54. The connecting rod 55 facilitates the connection and separation of the square tubes 54 and the connecting plate 51, while the pull plate 56 allows for easy control of the movement of the connecting rod 55. A spring 57 is fitted onto the surface of the connecting rod 55, with both ends of the spring 57 fixedly connected to the square tube 54 and the pull plate 56, respectively. The spring 57 ensures a stable connection between the connecting rod 55 and the square tube 54, and also restricts the position of the connecting rod 55.

[0034] Reference Figure 1 and Figure 2 as well as Figure 5 As shown, specifically, the control device 6 includes four first clamping blocks 61, all of which are fixedly connected to the side of the pull plate 56 away from the square tube 54. A telescopic plate 62 is rotatably connected to the inner wall of each of the four first clamping blocks 61. The telescopic plate 62, rotatably connected to the inner wall of the first clamping blocks 61, can rotate. By setting the telescopic plate 62 and the first clamping blocks 61, the movement of the pull plate 56 can be controlled. A second clamping block 63 is rotatably connected to the surface of the telescopic plate 62, and a control plate 64 is fixedly connected to the side of the second clamping block 63 away from the first clamping block 61. By setting the second clamping block 63, the control plate 64 and the telescopic plate 62 can be connected. By setting the control plate 64, the rotation and extension / retraction of the telescopic plate 62 can be controlled.

[0035] Two clamping plates 65 are fixedly connected to the upper surface of the control plate 64, and a rotating plate 66 is rotatably connected to the surfaces of the two clamping plates 65. By setting the clamping plates 65, the rotating plate 66 can be connected to the control plate 64, so that the rotation of the rotating plate 66 can drive the movement of the control plate 64.

[0036] Working principle: Before using the UAV oblique photogrammetry equipment, the connecting rod 55 is first slid along the inner wall of the square tube 54 by the pull plate 56, causing the pull plate 56 to move away from the square tube 54. Then, the connecting plate 51 is moved closer to the square tube 54. The pull plate 56 is released, and under the action of the spring 57, the connecting rod 55 moves closer to the connecting plate 51, completing the installation and fixation of the protective ring 52. After that, the UAV oblique photogrammetry equipment can be started to collect images using the camera 4 on the mounting ring 3. When the UAV oblique photogrammetry equipment is bumped, the "U"-shaped rod 53 takes the place of the body 1 to collide. During the collision, the "U"-shaped rod 53 drives the slider 58 to slide on the groove surface of the protective ring 52. At the same time, the damper 59 reduces the impact force of the "U"-shaped rod 53 collision, thereby achieving the protective effect on the wing 2. By setting the protective device 5, the UAV oblique photogrammetry equipment can be protected, minimizing the possibility of damage to the wing 2 when the UAV oblique photogrammetry equipment is bumped. This ensures that the UAV oblique photogrammetry equipment will not be affected by the bumps and minimizes the repair costs caused by the damage to the wing 2.

[0037] When the protective ring 52 needs to be installed or removed, first press the rotating plate 66 to control the rotation of the two rotating plates 66. At this time, the rotating plate 66 rotates on the surface of the clamping plate 65, thereby pushing the control plate 64 to move through the clamping plate 65. The movement of the control plate 64 causes the second clamping block 63 to rotate on the surface of the telescopic plate 62, and at the same time drives the telescopic plate 62 to extend. At this time, the telescopic plate 62 rotates on the inner wall of the first clamping block 61, and controls the pull plate 56 to drive the connecting rod 55 to move. Then the protective ring 52 is installed. After the protective ring 52 is installed, the rotating plate 66 is released. At this time, under the action of the spring force of the spring 57, the rotating plate 66 rotates away from the machine body 1. By setting the control device 6, the four connecting rods 55 can be moved synchronously, thereby simplifying the operation of installing and removing the protective ring 52 as much as possible, and improving the convenience and efficiency of installing and removing the protective ring 52.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
