Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an UAV device for automatic surveying. Background Technology

[0002] In fields such as geological exploration, land surveying, engineering construction, and disaster monitoring, traditional surveying methods rely on manual on-site measurement or manned aircraft operations, which suffer from problems such as low efficiency, high cost, and high risk.

[0003] Automated surveying drones typically consist of a flight platform, navigation and positioning system, payload, data processing module, and ground control system. Their working principle is as follows: operators define the survey area and set parameters on the ground system. The drone takes off autonomously and flies along the planned route. The payload collects data synchronously, the navigation system corrects the trajectory in real time, obstacle avoidance sensors ensure flight safety, and the drone automatically returns to base upon completion. The data is then processed by the module to generate directly applicable survey results. In terms of operation, only 1-2 people are needed on the ground to complete equipment checks and parameter settings. The drone can then automatically execute the survey task. Real-time footage can be viewed through the ground station during the process, and data can be exported for further analysis after the task is completed.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional drones require manual preset waypoints and cannot adapt to changes in terrain in real time, requiring repeated stops for adjustments. Especially in complex scenarios such as logistics and tourism, the efficiency of task completion is low. In view of this, we propose an automatic surveying drone equipment. Utility Model Content

[0007] An automated surveying drone device includes a bottom outer shell of a frame, a top outer shell of a frame fixedly mounted on the bottom outer shell, and a storage assembly provided on the bottom outer shell, the storage assembly comprising:

[0008] An integrated automatic route survey and planning module is provided. The bottom shell of the frame is fixedly installed with the integrated automatic route survey and planning module, the laser origin database establishment module and the GPS positioning unit. A high-definition camera is fixedly installed at the bottom of the bottom shell of the frame. An upper hinge frame is fixedly installed on the top shell of the frame and a lower hinge frame is fixedly installed on the bottom shell of the frame.

[0009] The mounting rod is hinged to one end of the upper and lower hinge frames via a mounting tube. A knob is rotatably mounted on the upper hinge frame, and a screw is fixedly mounted on the knob. A nut is fixedly mounted on the lower hinge frame. A mounting bracket is fixedly mounted on the other end of the mounting rod. A transmission rod is rotatably mounted on the mounting bracket. A large gear is fixedly mounted on the transmission rod. A propeller is fixedly mounted on the transmission rod. A dust cover is snapped onto the mounting bracket.

[0010] A high-speed motor is fixedly mounted on the mounting bracket. A transmission gear is fixedly mounted on the output end of the high-speed motor. A square tube is fixedly mounted inside the mounting bracket. A limit groove is formed on the square tube. One end of a helical spring is fixedly mounted inside the mounting bracket. A rubber block is fixedly mounted on the other end of the helical spring. A square rod is fixedly mounted on the rubber block. A limit block is fixedly mounted on the square rod.

[0011] In a further embodiment, multiple sets of the upper hinge frame, lower hinge frame, mounting tube, knob, screw, nut, mounting rod, mounting bracket, transmission rod, large gear, propeller, dust cover, high-speed motor, transmission gear, square tube, limiting groove, square rod, limiting block, rubber block, and helical spring are provided.

[0012] In a further embodiment, the screw passes through the upper hinge frame, the lower hinge frame, the mounting tube, and the mounting rod and is threaded onto the nut. The large gear meshes with the transmission gear, and the large gear and the transmission gear are located below the dust cover.

[0013] In a further embodiment, the square rod slides inside the square tube, the limiting block slides inside the limiting groove, and the rubber block is positioned below the mounting frame.

[0014] In a further embodiment, a positioning component is provided on the bottom outer shell of the frame. The positioning component includes a limiting groove. A limiting groove is provided on the mounting rod. One end of a positioning spring is fixedly installed inside the mounting rod. A sliding plate is fixedly installed on the other end of the positioning spring. A spherical positioning block is fixedly installed on the sliding plate. A block is fixedly installed on the lower hinge frame. A positioning groove is provided on the block.

[0015] In a further embodiment, multiple sets of the limiting groove, positioning spring, sliding plate, spherical positioning block, square block, and positioning groove are provided.

[0016] In a further embodiment, the slide plate slides inside the limiting groove, and the spherical positioning block is positioned above the block and the positioning groove, with the spherical positioning block corresponding to the position of the positioning groove.

[0017] Compared with the prior art, this utility model provides an unmanned aerial vehicle (UAV) device for automatic surveying, which has the following beneficial effects:

[0018] 1. This automated surveying drone equipment, in order to meet the route planning needs of logistics, tourism and other scenarios, is equipped with a storage component. This component works in conjunction with an integrated automatic route surveying and planning module, a laser origin database establishment module and a GPS positioning unit. It collects terrain data through a high-definition camera, automatically generates compliant routes, establishes a geographic database through a laser radar, and simultaneously drives a large gear through a high-speed motor via a transmission gear to ensure stable rotation of the propeller and provide sufficient lift. Rotating the knob drives the screw to screw into the nut, causing the mounting rod to fold around the hinge frame. The dust cover protects the transmission components, the helical spring pushes the rubber block to buffer landing vibration, and the square rod and limit block ensure the rubber block is deflected.

[0019] 2. To enhance the structural stability of this automated surveying drone equipment, a positioning component is incorporated. When the mounting rod is unfolded, the positioning spring pushes the sliding plate along the limiting groove, causing the spherical positioning block to engage with the positioning groove of the cube, locking the angle of the mounting rod and ensuring the propeller is under balanced force. When folded, the spherical positioning block is compressed by external force, causing the positioning spring to disengage from the positioning groove, achieving smooth folding. Multiple positioning units are symmetrically distributed, reducing the coaxiality error after the mounting rod is unfolded and preventing structural sway from affecting the surveying accuracy of the high-definition camera and lidar.

[0034] Please see Figures 1-8 This utility model provides a technical solution:

[0035] An automated surveying drone device includes a bottom shell 1 and a top shell 2 fixedly mounted on the bottom shell 1.

[0036] In one embodiment of this utility model, a storage component 3 is provided on the bottom outer shell 1 of the rack. The storage component 3 includes an integrated automatic route survey and planning module 31. The integrated automatic route survey and planning module 31, a laser origin database establishment module 32, and a GPS positioning unit 33 are fixedly installed on the bottom outer shell 1 of the rack. A high-definition camera 34 is fixedly installed at the bottom of the bottom outer shell 1 of the rack. An upper hinge frame 35 is fixedly installed on the top outer shell 2 of the rack. A lower hinge frame 36 is fixedly installed on the bottom outer shell 1 of the rack. Mounting rods are hinged to the upper hinge frame 35 and the lower hinge frame 36 through mounting tubes 37. At one end of mounting rod 311, a knob 38 is rotatably mounted on the upper hinge frame 35, and a screw 39 is fixedly mounted on the knob 38. A nut 310 is fixedly mounted on the lower hinge frame 36. At the other end of mounting rod 311, a mounting bracket 312 is fixedly mounted. A transmission rod 313 is rotatably mounted on the mounting bracket 312. A large gear 314 is fixedly mounted on the transmission rod 313. A propeller 315 is fixedly mounted on the transmission rod 313. A dust cover 316 is snapped onto the mounting bracket 312. A high-speed motor 317 is fixedly mounted on the mounting bracket 312. A transmission gear 318 is fixedly mounted on the output end of the high-speed motor 317. A square tube 319 is fixedly installed inside the mounting bracket 312. A limit groove 320 is provided on the square tube 319. One end of a helical spring 324 is fixedly installed inside the mounting bracket 312. A rubber block 323 is fixedly installed on the other end of the helical spring 324. A square rod 321 is fixedly installed on the rubber block 323. A limit block 322 is fixedly installed on the square rod 321. Other components include an upper hinge bracket 35, a lower hinge bracket 36, a mounting tube 37, a knob 38, a screw 39, a nut 310, a mounting rod 311, a mounting bracket 312, a transmission rod 313, a large gear 314, a propeller 315, a dust cover 316, and a high-speed motor. Multiple sets of components are provided, including transmission gear 317, transmission gear 318, square tube 319, limiting groove 320, square rod 321, limiting block 322, rubber block 323, and helical spring 324. Screw 39 passes through upper hinge frame 35, lower hinge frame 36, mounting tube 37, and mounting rod 311 and is threaded onto nut 310. Large gear 314 meshes with transmission gear 318. Large gear 314 and transmission gear 318 are located below dust cover 316. Square rod 321 slides inside square tube 319. Limiting block 322 slides inside limiting groove 320. Rubber block 323 is located below mounting frame 312.

[0037] In this embodiment, before executing a task, based on actual needs such as planning transportation routes in logistics and distribution or planning sightseeing routes in tourist scenes, the integrated automatic route survey and planning module 31 in the storage component 3 is activated. This module works in conjunction with the laser origin database establishment module 32 and the GPS positioning unit 33. The high-definition camera 34 is activated to capture images of the surrounding terrain and collect image data. The laser origin database establishment module 32 uses lidar technology to emit laser beams and receive reflected signals to establish a high-precision geographic database, providing detailed terrain information for route planning. The GPS positioning unit 33 receives signals emitted by multiple GPS satellites in space and calculates the position of the satellite based on the signal propagation time difference. The machine's own position information is fed back to the integrated automatic route survey and planning module 31. Based on terrain data collected by the high-definition camera 34, the geographic database generated by the laser origin database establishment module 32, and the position information provided by the GPS positioning unit 33, the integrated automatic route survey and planning module 31 automatically generates a compliant route that meets the needs of the actual scenario using a specific algorithm. When takeoff is required to perform a mission, the high-speed motor 317 is activated. The output of the high-speed motor 317 drives the transmission gear 318 to rotate. Since the large gear 314 meshes with the transmission gear 318, the large gear 314 rotates accordingly, thereby driving the transmission rod 313 and the propeller 315 fixed on the transmission rod 313 to rotate at high speed. The rotating propeller 315 pushes air to generate upward lift. When the lift exceeds the drone's own weight, the drone takes off. Multiple propellers 315 work together to ensure the drone obtains sufficient and balanced lift for stable flight. To store the drone, turn knob 38. Knob 38 drives screw 39 to rotate. Since screw 39 is threaded onto nut 310, it gradually screws into nut 310 during rotation, causing mounting rod 311 to fold around mounting tube 37 between upper hinge frame 35 and lower hinge frame 36. This reduces the overall size of the drone, making it easier to store and carry. During the rotation of propellers 315, dust cover 316 controls the transmission gears 314, 318, etc. The moving parts serve a protective function, preventing dust and debris from entering and affecting transmission efficiency or damaging components. When the drone lands, the rubber block 323 under the mounting bracket 312 first contacts the ground. The rubber block 323 is connected to the square rod 321. The limiting block 322 on the square rod 321 slides in the limiting groove 320 of the square tube 319. The helical spring 324 is in a compressed state. After the rubber block 323 is subjected to the impact force of the ground, it compresses the helical spring 324 through the square rod 321. The elastic deformation of the helical spring 324 plays a buffering role, reducing the vibration when the drone lands and protecting the internal precision components. The limiting block 322 cooperates with the limiting groove 320 to ensure that the rubber block 323 will not shift during the buffering process and will always be subjected to vertical force.

[0038] In one embodiment of this utility model, a positioning component 4 is provided on the bottom outer shell 1 of the frame. The positioning component 4 includes a limiting groove 41. A limiting groove 41 is provided on the mounting rod 311. One end of a positioning spring 42 is fixedly installed inside the mounting rod 311. A sliding plate 43 is fixedly installed on the other end of the positioning spring 42. A spherical positioning block 44 is fixedly installed on the sliding plate 43. A block 45 is fixedly installed on the lower hinge frame 36. A positioning groove 46 is provided on the block 45. Multiple sets of limiting grooves 41, positioning springs 42, sliding plates 43, spherical positioning blocks 44, blocks 45 and positioning grooves 46 are provided. The sliding plate 43 slides inside the limiting groove 41. The spherical positioning block 44 is located above the blocks 45 and the positioning groove 46. The spherical positioning block 44 and the positioning groove 46 are positioned corresponding to each other.

[0039] In this embodiment, during the takeoff preparation phase of the UAV, the mounting rod 311 unfolds from its folded state. At this time, the positioning spring 42 inside the mounting rod 311 is in a compressed state. When the mounting rod 311 unfolds to a predetermined angle, the positioning spring 42 restores its elastic deformation, pushing the sliding plate 43 to slide along the limiting groove 41 on the mounting rod 311. The sliding plate 43 drives the spherical positioning block 44 to move until the spherical positioning block 44 is engaged in the positioning groove 46 of the fixed square block 45 on the lower hinge frame 36. The positioning components 4 on multiple mounting rods 311 work synchronously to lock the angle of the mounting rod 311, so that the mounting rod 311 remains stable during flight. To ensure the propeller 315 is in force balance when generating lift during rotation, when the UAV needs to be stored after completing its mission, an external force is applied to the mounting rod 311 to fold it. During this process, the spherical positioning block 44 is squeezed by the block 45, overcoming the elastic force of the positioning spring 42, compressing the positioning spring 42 and disengaging it from the positioning groove 46, thus achieving smooth folding of the mounting rod 311. Multiple positioning units are symmetrically distributed on the UAV's frame, effectively reducing the coaxiality error after the mounting rod 311 is unfolded, avoiding the impact of structural swaying on the shooting stability of the high-definition camera 34 and the survey accuracy of the lidar, and ensuring that the data obtained by the UAV during flight survey is accurate and reliable.

[0040] In this application, all electrical components are electrically connected to the controller and the power supply. The controller is a conventional and known device that can control the integrated automatic route survey and planning module 31, the laser origin database establishment module 32, the GPS positioning unit 33, the high-definition camera 34, and the high-speed motor 317. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. In addition, the standard parts are all conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art.

[0041] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that each electrical appliance can work normally. The components are all general standard parts or components known to those skilled in the art.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art.
