[0002] With the rapid development of technology, more and more professional equipment is being used in outdoor surveying and mapping, replacing traditional simple measuring tools and providing fast and accurate measurement data for surveying. Typically, laser rangefinders and ultrasonic rangefinders play an important role in measuring target distance, target size, water flow depth, and other fields.

[0003] In recent years, with the development of UAV technology, the use of UAVs to detect targets such as target distance, target size, and water flow depth has become a new development direction in the surveying field, further improving surveying efficiency and flexibility.

The surveying drone 6 is mounted on the top of the self-leveling bracket via a displacement guiding mechanism 5. The displacement guiding mechanism 5 includes a vertical guide rod 51 suspended from the top of the self-leveling bracket. A rotating seat 52 is rotatably mounted on the top of the vertical guide rod 51. A horizontal guide rod 53 is horizontally mounted on the side of the rotating seat 52. The vertical guide rod 51 and the horizontal guide rod 53 are multi-stage telescopic rods. A lifting latch 62 is provided at the bottom end of the horizontal guide rod 53. A locking seat 21 is provided on the top of the self-leveling bracket. The lifting latch 62 is movably connected to the locking seat 21. The surveying drone 6 is connected to the top end of the horizontal guide rod 53. A surveying probe group 61 is mounted on the surveying drone 6. The surveying probe group 61 includes a laser ranging probe, an ultrasonic ranging probe, and a camera.

[0036] The self-leveling bracket is equipped with a controller and a wireless communication module. The controller is electrically connected to the self-leveling bracket and the surveying drone.

[0037] This application utilizes a self-leveling bracket to automatically level itself, providing a foundation for the measurement of the surveying drone 6. Users can use mobile terminals or other remote control devices to communicate with the controller via a wireless communication module, controlling the surveying drone 6 to move vertically or horizontally under the constraints of the vertical guide rod 51 and horizontal guide rod 53 of the displacement guiding mechanism 5. The surveying probe group 61 is used to measure the survey target, which helps to reduce the operation difficulty of the surveying drone 6 and avoid damage to the surveying drone 6 due to operational errors. At the same time, the constraint and guidance of the displacement guiding mechanism 5 also helps to reduce or even avoid the influence of outdoor wind, which is conducive to the accurate hovering of the surveying drone 6 and improves the measurement accuracy.

[0038] Preferably, the laser ranging probe, the ultrasonic ranging probe, and the camera are respectively mounted on the surveying UAV 6 via a displacement gimbal. The displacement gimbal shown is an electric gimbal, which is commonly used for automatic adjustment of the camera's shooting direction. The specific structure will not be described in detail in this application.

Three leveling telescopic mechanisms 3 are evenly hinged to the top of the support base 1 along its central axis. The top end of the leveling telescopic mechanism 3 is hinged to the bottom of the working base 2. A gyroscope is embedded inside the working base 2.

[0040] The user manually extends the tripod 4, and the level of the top surface of the working seat 2 is detected inside. The detection data is sent to the controller, which controls each leveling telescopic mechanism 3 to extend or retract until the level meets the preset requirements.

[0041] Preferably, a tripod tightening mechanism 7 is provided at the bottom of the support base 1. The tripod tightening mechanism 7 includes a first lifting rod 71 suspended at the bottom of the support base 1. A clamping disc 72 is provided at the bottom end of the lifting part of the first lifting rod 71. Three clamping slots are evenly opened on the side of the clamping disc 72 around its central axis. The width of the clamping slots is adapted to the diameter of the three supporting legs of the tripod 4. A first clamping mechanism 74 is provided in the clamping slots and is movably connected to the supporting legs of the tripod 4.

[0042] When this application is not in use, the controller controls the first lifting rod 71 to move the clamping disc 72 to a predetermined position.

[0043] Furthermore, a pressure probe 73 is provided at the bottom of the clamping disc 72. The pressure probe 73 is used to provide the surveying UAV 6 with the distance data between the working seat 2 and the ground. After the working seat 2 is leveled, the controller controls the first lifting rod 71 to move the clamping disc 72 downward until the pressure probe 73 contacts the ground and generates pressure data.

[0044] Specifically, the first clamping mechanism 74 includes a first telescopic mechanism symmetrically embedded in the side wall of the clamping groove. The telescopic shaft ends of the two first telescopic mechanisms are connected to the first clamping plates. The two first clamping plates move against the symmetrical side wall of the tripod 4 support leg.

[0045] Preferably, the end sidewall of the clamping groove near the center of the clamping disk 72 is arc-shaped.

[0046] Specifically, the lifting latch 62 includes a second lifting rod that is vertically mounted at the bottom of the horizontal guide rod 53. The bottom end of the lifting shaft of the second lifting rod is provided with a latch body. The top of the locking seat 21 is provided with a locking groove. The symmetrical sidewalls of the locking groove are respectively embedded with second telescopic mechanisms. The telescopic shaft end of the second telescopic mechanism is provided with a second clamping block. The two second clamping blocks move against the symmetrical sidewalls of the latch body.

[0047] The lifting latch 62 and locking seat 21 are used to fix the surveying drone 6 on the top of the work seat 2. After the surveying drone 6 completes the measurement operation and resets, the controller controls the second lifting rod to drive the latch body to insert into the locking groove. The two second telescopic mechanisms drive the second clamping blocks to simultaneously abut against the symmetrical side wall of the latch body to clamp the latch body and thus fix the surveying drone 6.

[0048] Preferably, the bottom end of the support leg of the tripod 4 is fitted with a rubber sleeve.

[0049] Preferably, a handle 11 is provided on one side of the support base 1.

[0050] The controller is an industrial computer device.

The first clamping plate and the second clamping block are made of elastic material. The wireless communication module is a 4G or 5G communication module.

[0051] Implementation principle:

[0052] The user sets up the tripod 4, and the controller, based on the data from the gyroscope, controls the leveling telescopic mechanism 3 of the self-leveling bracket to automatically level the working seat 2. The controller controls the locking seat 21 to release the lifting latch 62, and the latch body of the lifting latch 62 disengages from the locking seat 21. Through wireless communication with the controller via a mobile terminal, the user controls the surveying drone 6 to move vertically or horizontally under the constraint of the vertical guide rod 51 and the horizontal guide rod 53 of the displacement guide mechanism 5, and uses the surveying probe group 61 to measure the survey target.
