Abstract

This utility model relates to the field of unmanned aerial vehicle (UAV) technology and discloses a convenient take-off and landing surveying UAV. The convenient take-off and landing surveying UAV includes a fuselage, with a mobile gimbal located at the center of the bottom end of the fuselage. Landing gear tops are fixedly mounted at both ends of the bottom of the fuselage, and mobile components are mounted on the landing gear. To improve the adaptability of the UAV itself, this convenient take-off and landing surveying UAV, through the inclusion of mobile components, works in conjunction with the fuselage, propellers, mobile gimbal, and surveying instrument to achieve surveying of target areas. During landing, a first asynchronous motor on the landing gear and a fixed block is activated, causing the rotating frame to rotate. A second asynchronous motor is activated, causing a hydraulic rod to rotate. Activating the hydraulic rod causes the piston rod to extend and retract, allowing multiple sets of piston rods to move along multiple axes, adapting to uneven road surfaces, thus facilitating take-off and landing and improving adaptability. A rubber ring is used to clean the piston rod when it retracts into the hydraulic rod.

Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a surveying UAV that is easy to take off and land. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently. UAVs use mapping instruments to produce digital line maps.

[0003] In existing technologies, surveying drones have shortcomings in take-off and landing. Traditional surveying drones have a simple landing gear structure that is in direct contact with the ground. When encountering uneven road surfaces, their stability during take-off and landing is poor, which brings many inconveniences to the drone's take-off and landing operations. They lack adjustment mechanisms to adapt to the take-off and landing requirements of uneven road surfaces, and their adaptability needs to be improved. Furthermore, it is inconvenient to sample the soil at the target location.

[0004] In view of this, we propose a mapping drone that is easy to take off and land. Utility Model Content

[0005] The purpose of this invention is to provide a surveying drone that is easy to take off and land, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A convenient take-off and landing mapping drone includes a fuselage, a propeller mounted at the top of the fuselage, a mobile gimbal mounted at the center of the bottom of the fuselage, a mapping instrument attached to the mobile gimbal, and landing gear tops fixedly mounted at both ends of the bottom of the fuselage. A moving component is mounted on the landing gear, the moving component comprising:

[0008] A fixed block is fixedly installed on the outer wall of the bottom end of the landing gear, a first asynchronous motor is fixedly installed on the top of the fixed block, and a rotating frame is fixedly installed on the bottom output end of the first asynchronous motor.

[0009] The second asynchronous motor is fixedly installed on the outer wall of the rotating frame. A hydraulic rod fixed end is fixedly installed at the output end of the second asynchronous motor, and a piston rod is fixedly installed at the piston end of the hydraulic rod.

[0010] A rubber ring is fixedly installed at the end of the hydraulic rod away from the rotating frame, and the rubber ring slides against the outer wall of the piston rod.

[0011] In a further embodiment, the propellers are provided in four sets, and the landing gear is provided in two sets, thereby enabling the drone body to operate better.

[0012] In a further embodiment, the fixed block, the first asynchronous motor, the rotating frame, the second asynchronous motor, the hydraulic rod, the piston rod, and the rubber ring are arranged in four sets, and the four sets of the fixed block, the first asynchronous motor, the rotating frame, the second asynchronous motor, the hydraulic rod, the piston rod, and the rubber ring are respectively arranged at the four corners of the bottom of the body, making the take-off and landing of the UAV more stable.

[0013] In a further embodiment, the end of the piston rod furthest from the rotating frame is configured as a bevel.

[0014] In a further embodiment, the landing gear is also equipped with a sampling component, which includes a multi-axis robotic arm. The fixed end of the multi-axis robotic arm is fixedly connected to the center of the outer wall at the bottom of the landing gear. A movable frame is fixedly installed on the movable end of the multi-axis robotic arm. A third asynchronous motor is fixedly installed on the outer wall of the movable frame. An active gear block is fixedly installed on the outside of the output shaft of the third asynchronous motor.

[0015] In a further embodiment, a driven gear block is rotatably mounted inside the movable frame, and the driving gear block meshes with the driven gear block.

[0016] In a further embodiment, sampling clips are hingedly mounted on both the driving gear block and the driven gear block. There are two sampling clips, and each of the two sampling clips is hingedly mounted with a hinge rod to the moving frame, which can sample the soil at the target location, thereby improving work efficiency.

[0017] Compared with the prior art, this utility model provides a surveying drone that is convenient for take-off and landing, and has the following beneficial effects:

[0018] 1. This convenient take-off and landing surveying drone, in order to improve the adaptability of the drone itself, is equipped with a mobile component, which works in conjunction with the fuselage, propellers, mobile gimbal, and surveying instrument to achieve surveying of the target area. When landing, the first asynchronous motor on the landing gear and fixed block is activated, causing the rotating frame to rotate. The second asynchronous motor is activated, causing the hydraulic rod to rotate. The hydraulic rod is activated, causing the piston rod to extend and retract. Thus, multiple sets of piston rods can move in multiple axes to adapt to uneven road surfaces, thereby facilitating take-off and landing and improving adaptability. The rubber ring is used to clean the piston rod when it retracts into the hydraulic rod.

[0019] 2. This convenient take-off and landing surveying drone, in order to facilitate soil sampling at target locations, is equipped with a sampling component. When the drone hovers on the target ground, the multi-axis robotic arm enables the mobile frame to move in multiple axes. The third asynchronous motor is activated, causing the drive gear block to rotate. This, combined with the transmission of the driven gear block and the hinge rod, allows the two sampling clamps to move towards each other. When the two clamps approach each other, soil samples can be taken at the target location, thereby improving work efficiency. Attached Figure Description

[0030] 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.

[0031] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0032] Please see Figures 1-6 This utility model provides a technical solution:

[0033] A surveying drone that is easy to take off and land includes a body 1, a propeller 2 is installed at the top of the body 1, and there are four sets of propellers 2. A mobile gimbal 3 is installed at the center of the bottom of the body 1, and a surveying instrument 4 is attached to the mobile gimbal 3. Landing gears 5 are fixedly installed at both ends of the bottom of the body 1, and there are two sets of landing gears 5, so that the drone body can operate better.

[0034] Specifically, when the mapping drone is started, the controller sends a start command to the drive motor of the propeller 2. The four propellers 2 begin to rotate, generating lift to lift the drone body 1 off the ground. The mobile gimbal 3 adjusts its attitude according to a preset program or real-time control signal to ensure that the mapping instrument 4 is aligned with the target mapping area. The mapping instrument 4 starts and begins to collect data on the target area (such as terrain scanning, image capture, etc.). The controller adjusts the speed and angle of each propeller 2 according to a preset flight path or real-time control signal to achieve stable flight of the drone. The mobile gimbal 3 continuously adjusts the orientation and angle of the mapping instrument 4 to ensure the integrity and accuracy of the mapping data. The mapping instrument 4 transmits the collected data to the data processing unit inside the drone body 1 in real time. After preliminary processing, the data is stored or transmitted back to the ground control station.

[0035] In one embodiment of this utility model, a moving component 6 is provided on the landing gear 5. The moving component 6 includes a fixed block 61. The fixed block 61 is fixedly installed on the outer wall of the bottom end of the landing gear 5. A first asynchronous motor 62 is fixedly installed on the top of the fixed block 61. A rotating frame 63 is fixedly installed on the bottom output end of the first asynchronous motor 62. A second asynchronous motor 64 is fixedly installed on the outer wall of the rotating frame 63. A fixed end of a hydraulic rod 65 is fixedly installed on the output end of the second asynchronous motor 64. A piston rod 66 is fixedly installed on the piston end of the hydraulic rod 65. The end of the hydraulic rod 65 away from the rotating frame 63 is fixedly installed... A rubber ring 67 is installed, which slides and fits against the outer wall of the piston rod 66. In addition, there are four sets of fixing blocks 61, first asynchronous motor 62, rotating frame 63, second asynchronous motor 64, hydraulic rod 65, piston rod 66 and rubber ring 67. The four sets of fixing blocks 61, first asynchronous motor 62, rotating frame 63, second asynchronous motor 64, hydraulic rod 65, piston rod 66 and rubber ring 67 are respectively set at the four corners of the bottom of the body 1, which makes the take-off and landing of the drone more stable. In addition, the end of the piston rod 66 away from the rotating frame 63 is set as a bevel.

[0036] In this embodiment, when the UAV approaches the target landing area, the controller sends a deployment command to the moving component 6. When the moving component 6 deploys, specifically, the first asynchronous motor 62 on the fixed block 61 starts, driving the rotating frame 63 to rotate; the second asynchronous motor 64 starts, driving the hydraulic rods 65 to rotate, adjusting the position of the piston rods 66. The inclined surfaces at the bottom of the four sets of piston rods 66 first contact the ground. Through the extension and retraction of their respective independent hydraulic rods 65 and piston rods 66, the hydraulic system monitors the force on each piston rod 66 in real time and feeds it back to the controller via pressure sensors. The controller dynamically adjusts the position of each set of hydraulic rods 65 based on the sensor data. The extension and retraction allow the four sets of piston rods 66 to maintain stable contact with the ground. When encountering uneven surfaces, the piston rods 66 in the raised areas experience increased pressure, causing the hydraulic system to automatically retract; the piston rods 66 in the recessed areas experience decreased pressure, causing the hydraulic system to automatically extend. When the UAV completes its operation and prepares for takeoff, the hydraulic rod 65 drives the piston rods 66 to retract. When the piston rods 66 pass through the rubber ring 67, the inner wall of the rubber ring 67 fits tightly against the outer wall of the piston rods 66, scraping off any attached dirt or impurities. After all four sets of piston rods 66 have fully retracted, the first asynchronous motor 62 and the second asynchronous motor 64 work together to return the landing gear 5 and the moving assembly 6 to their initial positions.

[0037] In one embodiment of this utility model, a sampling component 7 is also provided on the landing gear 5. The sampling component 7 includes a multi-axis robotic arm 71. The fixed end of the multi-axis robotic arm 71 is fixedly connected to the center of the outer wall of the bottom end of the landing gear 5. A movable frame 72 is fixedly installed on the movable end of the multi-axis robotic arm 71. A third asynchronous motor 73 is fixedly installed on the outer wall of the movable frame 72. A drive gear block 74 is fixedly installed on the outside of the output shaft of the third asynchronous motor 73. In addition, a driven gear block 75 is rotatably installed inside the movable frame 72. The drive gear block 74 meshes with the driven gear block 75. In addition, sampling clips 76 are hingedly installed on both the drive gear block 74 and the driven gear block 75. There are two sampling clips 76. The two sampling clips 76 are respectively hingedly installed with hinge rods 77 between them and the movable frame 72, which can sample the soil at the target location, thereby improving work efficiency.

[0038] In this embodiment, the drone flies to and hovers above the target sampling area. The controller sends a command to the multi-axis robotic arm 71. The multi-axis robotic arm 71, according to a preset program or real-time control signal, drives the moving frame 72 to move above the sampling position. The third asynchronous motor 73 starts, driving the drive gear block 74 to rotate. Through gear meshing, the drive gear block 75 rotates synchronously. The rotation of the drive gear block 74 and the drive gear block 75, through the transmission action of the hinge rod 77, causes the two sampling clamps 76 to move towards each other. During the closing process, the target soil sample is gradually clamped until the preset clamping force is reached. The multi-axis robotic arm 71 lifts the sampled sample to a safe height to avoid collision with ground obstacles. The drone carries the sample back to the designated area. The multi-axis robotic arm 71 moves the sampling clamp 76 above the sample collection device. The third asynchronous motor 73 reverses, driving the active gear block 74 and the driven gear block 75 to rotate in opposite directions, causing the two sampling clamps 76 to move in opposite directions. The sampling clamps 76 open, and the soil sample falls into the collection device, completing the sampling process.

[0039] All electrical components appearing in this application are electrically connected to the controller and power supply inside the machine body 1. The controller is a conventional and known device that can control the machine body 1, the mobile gimbal 3, the surveying instrument 4, the first asynchronous motor 62, the second asynchronous motor 64, the hydraulic rod 65, the multi-axis robotic arm 71, and the third asynchronous motor 73. 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. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0040] 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. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
