Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) surveying and mapping technology, specifically to a UAV surveying and mapping data acquisition device. Background Technology
[0002] The increasing maturity of drone technology has led to its widespread application in civilian fields such as mapping, disaster monitoring, and geological exploration. During flight, drones use onboard small cameras to capture images and videos of the target area, then transmit this data back to the control center. This allows management personnel to dynamically understand the actual situation of the target area, providing necessary reference for subsequent related work.
[0003] The lower part of the surveying drone is equipped with a camera component for surveying. The camera component is fixedly connected to the drone body. The camera component lacks a protective structure. When the surveying drone is not performing surveying operations, the camera component is exposed to the outside for a long time and is easily damaged. Utility Model Content

The UAV body includes a flight platform, and a camera assembly is provided at the lower end of the flight platform. The protective structure includes an annular base located around the flight platform. The annular base has a first lifting plate, a second lifting plate, a third lifting plate, and a fourth lifting plate built into it. Support legs are fixedly provided on the outer sides of the first and second lifting plates. Four sets of electric cylinders are installed at the top of the annular base.
[0006] The four sets of electric cylinders correspond to the first lifting plate, the second lifting plate, the third lifting plate, and the fourth lifting plate, respectively.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a UAV mapping data acquisition device, including a UAV body 1 and a protective structure 2. The UAV body 1 includes a flight platform 11, and a camera assembly 3 is provided at the lower end of the flight platform 11. The protective structure 2 includes an annular base 21, which is located on the periphery of the flight platform 11. The annular base 21 has a first lifting plate 22, a second lifting plate 23, a third lifting plate 24 and a fourth lifting plate 25 built inside. Support legs 26 are fixedly provided on the outer sides of the first lifting plate 22 and the second lifting plate 23. Four sets of electric cylinders 27 are installed at the top of the annular base 21.
[0024] The drone body 1 and camera assembly 3 constitute a surveying drone. A protective structure 2 is added to the drone body 1 to protect the camera assembly 3. The first lifting plate 22, the second lifting plate 23, the third lifting plate 24, and the fourth lifting plate 25 can all slide under the drive of the electric cylinder 27. When the drone body 1 takes off for surveying, the electric cylinder 27 drives the first lifting plate 22, the second lifting plate 23, the third lifting plate 24, and the fourth lifting plate 25 to rise. Figure 1 and Figure 2 As shown, at this time, the first lifting plate 22, the second lifting plate 23, the third lifting plate 24, and the fourth lifting plate 25 will not obstruct the camera assembly 3, and the camera assembly 3 can perform normal surveying. When the surveying is completed and the camera is ready to land, the electric cylinder 27 drives the first lifting plate 22, the second lifting plate 23, the third lifting plate 24, and the fourth lifting plate 25 to descend a certain distance, such as... Figure 3 As shown, the legs 26 of the first lifting plate 22 and the second lifting plate 23 are used to support the main body of the drone 1 to ensure that the main body of the drone 1 can land stably. The first lifting plate 22, the second lifting plate 23, the third lifting plate 24 and the fourth lifting plate 25 together form a cover structure, which covers the outside of the camera assembly 3 to provide safety protection for the camera assembly 3.
[0025] When maintenance is required on camera assembly 3, the third lifting plate 24 and the fourth lifting plate 25 can be raised separately.
[0026] Among them, the four sets of electric cylinders 27 correspond to the first lifting plate 22, the second lifting plate 23, the third lifting plate 24 and the fourth lifting plate 25 respectively. The push rod of the electric cylinder 27 is fixedly connected to one end of the lifting plate. One set of electric cylinders 27 corresponds to one set of lifting plates and can lift the lifting plate.
[0027] Among them, the first lifting plate 22, the second lifting plate 23, the third lifting plate 24 and the fourth lifting plate 25 are all set as arc-shaped structures, and the four sets of arc-shaped lifting plates together form a circular cover structure.
[0028] The annular base 21 has an arc-shaped groove. The first lifting plate 22, the second lifting plate 23, the third lifting plate 24 and the fourth lifting plate 25 are all slidably connected to the arc-shaped groove. The first lifting plate 22, the second lifting plate 23, the third lifting plate 24 and the fourth lifting plate 25 slide along the arc-shaped groove under the drive of the electric cylinder 27.
[0029] The camera assembly 3 includes a pan-tilt structure, and the pan-tilt structure includes a first motor 31. The output shaft of the first motor 31 is connected to a drive disk 32. The drive disk 32 is fixedly connected to a drive frame 33. The drive frame 33 is fixedly connected to a U-shaped frame 34.
[0030] A second motor 35 is installed on one side of the U-shaped frame 34. The output shaft of the second motor 35 is connected to the drive shaft 36, and the drive shaft 36 is connected to the camera body 37.
[0031] The first motor 31 drives the camera body 37 at the end to rotate in the left and right direction, and the second motor 35 drives the camera body 37 at the end to rotate in the up and down direction. By controlling the rotation direction and number of rotations of the output shafts of the first motor 31 and the second motor 35, the angle of the camera body 37 can be flexibly adjusted, making the survey data acquisition more comprehensive.
[0032] The main body of the drone 1 includes a power mechanism 12, which mainly provides flight power and includes equipment such as motors, power supplies, and batteries.
[0033] The main body of the drone 1 includes a navigation and flight control mechanism 13, which is used to locate and navigate the drone.
[0034] The first lifting plate 22, the second lifting plate 23, the third lifting plate 24 and the fourth lifting plate 25 together constitute a protective cover structure, which covers the outside of the camera assembly 3 to provide safety protection for the camera assembly 3.
[0035] Working principle: During use, the power mechanism 12 of the main body 1 of the UAV provides flight power, the navigation and flight control mechanism 13 positions and navigates the UAV, the camera assembly 3 performs mapping, and the mapping data is collected. When the main body 1 of the UAV takes off to perform mapping, the electric cylinder 27 drives the first lifting plate 22, the second lifting plate 23, the third lifting plate 24, and the fourth lifting plate 25 to rise, as shown. Figure 1 and Figure 2 As shown, the lifting platform structure at this time will not obstruct the camera assembly 3, and the camera assembly 3 can perform normal surveying. When the surveying is completed and the camera is ready to land, the electric cylinder 27 drives the first lifting platform 22, the second lifting platform 23, the third lifting platform 24, and the fourth lifting platform 25 to descend a certain distance, as shown. Figure 3 As shown, the legs 26 of the first lifting plate 22 and the second lifting plate 23 are used to support the main body 1 of the drone, ensuring that the main body 1 of the drone can land stably. The four lifting plates together form a cover structure, which covers the outside of the camera assembly 3 and provides safety protection for the camera assembly 3. When the camera assembly 3 needs to be maintained, the third lifting plate 24 and the fourth lifting plate 25 can be raised separately.
