Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to an aerial surveying UAV. Background Technology

[0002] In the field of modern land surveying, aerial surveying drones have become core equipment for acquiring geospatial data due to their advantages of flexibility, high efficiency, and low cost. They are widely used in scenarios such as land surveys, urban and rural planning, and disaster monitoring. However, in actual operations, these devices still face three major challenges that restrict the further improvement of surveying accuracy and efficiency. Aerial surveying drones, also known as aerial photogrammetry drones, are intelligent unmanned aerial vehicles equipped with professional image acquisition equipment. They acquire high-resolution ground image data at low altitudes through autonomous or semi-autonomous flight and combine positioning, navigation, and data processing technologies to achieve topographic mapping, 3D modeling, and geographic information collection.

[0003] However, existing aerial survey drones have the following drawbacks: (1) The support structure of traditional aerial survey UAVs is usually a fixed structure. Although the vertical support can ensure the stability when parked, the protruding support will generate additional airflow resistance during flight, causing the fuselage to shake, the image to be blurred, and even the aerial survey field of view to be affected by the support. (2) Aerial survey equipment needs to cope with complex environments during operation. If the protection is tight, it can protect the equipment, but it will lead to complicated disassembly and assembly, and a lot of time will be spent on maintenance or replacement of the equipment.

[0004] Therefore, this utility model provides an aerial surveying drone. Utility Model Content

[0005] (a) Technical problems to be solved The problem solved by this utility model is to provide a more practical aerial survey drone that addresses the issues mentioned in the background art, such as the additional airflow resistance caused by the protruding bracket during flight and the cumbersome disassembly and assembly process despite protecting the equipment.

[0006] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: an aerial surveying drone, including a drone, with brackets provided on both sides of the drone, a cavity opened inside the drone, an adjustment component provided inside the cavity, a mounting base installed at the bottom of the drone, aerial surveying equipment installed at the bottom of the mounting base, and a protective component provided on the surface of the mounting base; The adjustment assembly includes a dual-head motor installed on the bottom wall of the cavity. Both output ends of the dual-head motor are splined to a transmission rod. One end of the transmission rod is fixedly connected to a worm gear. A worm wheel meshes with the surface of the worm gear. A circular hole is opened on one side of the worm wheel. A connecting rod is fixedly connected to the inner side wall of the circular hole. The top of the bracket is installed on the surface of the connecting rod. The protective assembly includes a mounting ring disposed on the surface of the mounting base. A protective cover is fixedly connected to the bottom of the mounting ring. The mounting ring has four cavities inside. Movable plates are movably connected to the inner sidewalls of the cavities. A spring is connected between one side of the movable plate and the inner sidewall of the cavity. A plug rod is fixedly inserted through one side of the movable plate. The surface of the mounting base has slots that are adapted to the plug rods. One end of the plug rod is inserted into the interior of the slot.

[0007] Optionally, a rubber pad is fixedly connected to the bottom of the bracket. The surface of the rubber pad is provided with anti-slip texture. The rubber pad is made of rubber material and has a certain degree of elasticity, which can buffer the impact force generated when the drone comes into contact with the ground when it is parked, and reduce the vibration impact on the body and internal components.

[0008] Optionally, two support blocks are fixedly connected to both sides of the drone. A circular hole is opened on the front of the support block, and the connecting rod is rotatably connected to the inside of the circular hole. The circular hole on the front of the support block is adapted to the connecting rod, which ensures the coaxiality and stability of the connecting rod during rotation, making the angle adjustment of the bracket more stable and precise.

[0009] Optionally, a retaining ring is fitted on the surface of the connecting rod, with one side of the retaining ring contacting the front of the support block. During the flight of the UAV and the adjustment of the bracket angle, the retaining ring ensures that the connecting rod will not move axially due to vibration or external force, thus ensuring the accuracy and stability of the bracket angle adjustment.

[0010] Optionally, the other end of the insertion rod extends to the outside of the mounting ring, and a pull ring is fixedly connected to the other end of the insertion rod. By pulling the pull ring, the operator can easily move the insertion rod into the cavity, so that the insertion rod can be pulled out of the slot.

[0011] Optionally, the inner wall of the cavity is provided with a rotating groove adapted to the worm. One end of the worm is rotatably connected to the inside of the rotating groove. The rotating groove can limit the radial displacement of the worm, ensuring that the worm and the worm wheel always maintain a good meshing state, thus ensuring the normal operation of the adjustment component.

[0012] (III) Beneficial Effects This utility model provides an aerial survey drone, which has the following beneficial effects: 1. Before takeoff, the vertical support of this aerial survey UAV provides stable support and prevents the fuselage from tilting when parked. After takeoff, the support turns to a horizontal position, which can minimize airflow resistance during low-altitude flight and reduce the impact and interference of airflow on the fuselage. This reduces the amplitude of fuselage vibration and indirectly ensures the clarity of the images captured by the aerial survey equipment. It also avoids image blurring caused by support obstruction or airflow disturbance, thus improving the accuracy of survey data.

[0013] 2. The protective cover of this aerial survey drone can provide physical protection for the aerial survey equipment during aerial survey operations, avoiding impact or contamination from tree branches, dust, raindrops, etc. during low-altitude flight, reducing equipment maintenance costs and operation downtime. It can be quickly disassembled and assembled without tools, improving maintenance efficiency and facilitating rapid inspection, lens cleaning, or model replacement of aerial survey equipment, reducing operation waiting time caused by equipment maintenance.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1 to 4This utility model provides a technical solution: an aerial surveying drone, including a drone 1, with brackets 101 on both sides of the drone 1, a cavity inside the drone 1, an adjustment component 2 inside the cavity, a mounting base 102 at the bottom of the drone 1, and an aerial surveying device 103 at the bottom of the mounting base 102, which is a core working component used to collect ground image data and is a key device for realizing land surveying functions; a protective component 3 is provided on the surface of the mounting base 102. The adjustment assembly 2 includes a dual-head motor 201 installed on the bottom wall of the cavity. It synchronously drives the transmission structure on both sides through two output ends to realize the attitude conversion of the bracket 101. Both output ends of the dual-head motor 201 are splined connected to transmission rods. One end of the transmission rod is fixedly connected to a worm 202, which transmits the rotational motion of the dual-head motor 201 to the worm wheel 203 and changes the transmission direction. The surface of the worm 202 is meshed with the worm wheel 203, which converts the rotational motion of the worm 202 into its own circular motion and realizes deceleration and torque increase. A circular hole is opened on one side of the worm wheel 203. A connecting rod 204 is fixedly connected to the inner wall of the circular hole, which transmits the rotational motion of the worm wheel 203 to the bracket 101 to realize the angle adjustment of the bracket 101. The top of the bracket 101 is installed on the surface of the connecting rod 204. The protective component 3 includes a mounting ring 301 disposed on the surface of the mounting base 102. A protective cover 302 is fixedly connected to the bottom of the mounting ring 301 to protect the aerial survey equipment 103 from the influence of the external environment and prevent damage to the equipment from branches, dust, raindrops, etc. during low-altitude flight. The mounting ring 301 has four cavities inside. A movable plate 303 is movably connected to the inner wall of the cavity. A spring 304 is connected between one side of the movable plate 303 and the inner wall of the cavity, which pushes the movable plate 303 and the insertion rod 305 to move outward, so that the insertion rod 305 automatically engages in the slot, thereby fixing the protective cover 302. The insertion rod 305 is fixedly inserted through one side of the movable plate 303. Through the cooperation with the slot, the mounting ring 301 is fixedly connected to the mounting base 102. The surface of the mounting base 102 has a slot adapted to the insertion rod 305. One end of the insertion rod 305 is inserted into the inside of the slot. A rubber pad 4 is fixedly connected to the bottom of the bracket 101. The surface of the rubber pad 4 is provided with anti-slip texture. The rubber pad 4 is made of rubber material and has a certain elasticity, which can buffer the impact force generated when the drone 1 is parked and comes into contact with the ground, and reduce the vibration impact on the body and internal components. Two support blocks 5 are fixedly connected to both sides of the drone 1. A circular hole is opened on the front of the support block 5. The connecting rod 204 is rotatably connected to the inside of the circular hole. The circular hole on the front of the support block 5 is compatible with the connecting rod 204, which ensures the coaxiality and stability of the connecting rod 204 during rotation, making the angle adjustment of the bracket 101 more stable and precise. A retaining ring 6 is fitted on the surface of the connecting rod 204. One side of the retaining ring 6 contacts the front of the support block 5. During the flight of the UAV 1 and the angle adjustment of the bracket 101, the retaining ring 6 ensures that the connecting rod 204 will not move axially due to vibration or external force, thus ensuring the accuracy and stability of the angle adjustment of the bracket 101. The other end of the insertion rod 305 extends to the outside of the mounting ring 301. A pull ring 7 is fixedly connected to the other end of the insertion rod 305. By pulling the pull ring 7, the operator can easily move the insertion rod 305 into the cavity and pull the insertion rod 305 out of the slot. The inner wall of the cavity is provided with a rotating groove that is compatible with the worm 202. One end of the worm 202 is rotatably connected to the inside of the rotating groove. The rotating groove can limit the radial displacement of the worm 202, ensuring that the worm 202 and the worm wheel 203 always maintain a good meshing state, thus ensuring the normal operation of the adjustment component 2.

[0018] In this invention, the working steps of the device are as follows: First step: After the UAV 1 takes off, the dual-head motor 201 inside the cavity starts. Its two output ends drive two transmission rods to rotate synchronously through splines, which in turn drives the worm gears 202 at both ends to rotate. The worm gears 202 and worm wheels 203 form a gear meshing structure. The rotational motion of the worm gears 202 is converted into the circular motion of the worm wheels 203. Since the worm wheels 203 are fixedly connected to the connecting rods 204 through the circular holes, the rotation of the worm wheels 203 will directly drive the connecting rods 204 to rotate synchronously. The top of the bracket 101 is fixed to the surface of the connecting rods 204. When the connecting rods 204 rotate in the circular holes of the support block 5, the bracket 101 changes its angle with the rotation of the connecting rods 204, gradually rotating from the vertical support state before takeoff to the horizontal state. The second step: Place the mounting ring 301 on the surface of the mounting base 102, aligning the insertion rod 305 on one side of the movable plate 303 with the slot on the surface of the mounting base 102. At this time, the movable plate 303 is pushed outward by the spring 304 in the cavity, and the insertion rod 305 automatically inserts into the slot under the elastic force of the spring 304, completing the fixation of the protective cover 302 and realizing the physical protection of the aerial survey equipment 103. Pull the pull ring 7 outside the mounting ring 301 outward, driving the insertion rod 305 to move into the cavity. At this time, the movable plate 303 compresses the spring 304, and the insertion rod 305 is pulled out of the slot. After the insertion rod 305 is completely disengaged from the slot, the mounting ring 301 and the protective cover 302 can be removed from the mounting base 102 for easy maintenance or replacement of the aerial survey equipment 103.
