Description

Technical Field

[0001] The utility model relates to the technical field of remote sensing mapping, in particular to an aerial remote sensing mapping unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicle remote sensing (UAVRS) utilizes advanced unmanned aerial vehicle (UAV) technology, remote sensing sensors, telemetry and remote control, communications, GPS differential positioning, and remote sensing applications to rapidly acquire spatial remote sensing information on land resources, the natural environment, and earthquake-stricken areas in an automated, intelligent, and specialized manner, and to perform remote sensing data processing, modeling, and application analysis. Due to their advantages of mobility, speed, and cost-effectiveness, UAV remote sensing systems have become a hot research topic worldwide. They have gradually evolved from research and development to practical application, becoming one of the key aerial remote sensing technologies of the future.

[0003] In the existing technology, when replacing parts of surveying and mapping drones, the process of replacing blade parts is relatively cumbersome, and most of them use connection methods such as plugging and welding. The above methods have problems such as inconvenience in disassembly or time-consuming disassembly during the application process or disassembly process.

[0004] When a surveying and mapping drone is flying and measuring, the motor drives the blades to rotate, and this rotation is often accompanied by vibration. When the blades rotate, the entire drone body will vibrate. The internal parts of the drone are usually relatively precise. Continuous vibration may cause parts damage or poor contact. When a large maneuver and brake occur, the vibration is even greater. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides an aerial remote sensing mapping UAV, which has the advantages of rapid assembly and disassembly and shock absorption effect, and solves the problems raised by the above-mentioned background technology.

[0006] The utility model provides the following technical solution: an aerial remote sensing mapping UAV, comprising a UAV body, a static shaft fixedly installed at the middle of the bottom of the UAV body, a sphere provided at the bottom of the static shaft, a rotating camera movably installed at the outer ring of the sphere at the bottom of the static shaft, a rotating sleeve fixedly installed on both sides of the static shaft at the bottom of the UAV body, a bracket rotatably installed inside the rotating sleeve, the outer ring of the UAV body is in a circular ring shape and a fixed sleeve is evenly fixed thereon, the outer ring of the fixed sleeve is threadedly sleeved with a connecting column, the outer ring of the fixed sleeve is located at the outer ring of the connecting column and is threadedly sleeved with an external connecting sleeve, a protective block is fixedly installed on the end of the connecting column away from the UAV body, and a fan blade device is rotatably installed on the top of the protective block.

[0007] Through the above-mentioned structural setting, a modular design of the fan blade device components is realized. When the structure is repaired or replaced after use, it can be quickly disassembled and assembled, thereby improving maintenance efficiency and operational flexibility. Not only does it improve maintenance efficiency, but it can also quickly adjust the UAV configuration according to mission requirements. Through the internal setting of the fan blade device, the dynamic vibration of the fuselage is reduced when the blades rotate, thereby reducing the vibration of the fuselage caused by the rotation of the blades.

[0008] Preferably, the fixed sleeve includes an inner sleeve and an outer sleeve, the outer sleeve is located at the inner ring of the inner sleeve, the inner sleeve and the outer sleeve are fixedly connected, the outer ring of the inner sleeve is provided with a thread groove A, the outer ring of the outer sleeve is provided with a thread groove B, and one side of the outer sleeve is symmetrically provided with an adaptation groove.

[0009] Through the above structural setting, the connecting column is used to be threadedly sleeved with the outer sleeve, and the outer connecting sleeve is used to be threadedly sleeved with the inner sleeve. The connecting column is fixed at the position of the outer ring of the fixed sleeve through the above threaded connection, and it is convenient to work during disassembly and assembly.

[0010] Preferably, a plug connector is rotatably installed inside the connecting column, and a connector head adapted to the adapting groove is symmetrically fixedly installed on one side of the plug connector. The connecting column is located on the outer ring of the outer sleeve and is provided with an inner sleeve, and the inner sleeve is fixedly connected to the connecting column. The inner ring of the inner sleeve is provided with a thread B, and the thread B is adapted to the thread groove B.

[0011] Through the above-mentioned structural setting, the initial position limitation of the connecting column on the side of the drone body is achieved by setting the plug connector and the inner sleeve, and at the same time, a connection effect is achieved. After the inner sleeve is connected to the outer sleeve, the position is initially fixed.

[0012] Preferably, the outer connecting sleeve is located on the outer ring of the connecting column, and the outer connecting sleeve is slidably installed on the outer ring of the connecting column. The outer ring of the inner connecting sleeve is provided with a clamping block, and the clamping block is a limit block of the outer connecting sleeve. The inner ring of the outer connecting sleeve is provided with a thread A, and the thread A is adapted to the thread groove A.

[0013] Through the above-mentioned structural setting, by sliding the outer connecting sleeve to the end of the outer ring of the connecting column and threadedly connecting it with the outer ring of the inner sleeve, the connection position is simultaneously limited and fixed.

[0014] Preferably, a motor is provided inside the protective block, the output shaft end of the motor is located at the top of the protective block and is fixedly connected to a rotating shaft, a horizontal axis is provided on the top of the rotating shaft, the angle between the horizontal axis and the rotating shaft is a vertical angle, and a heat dissipation plate is provided on one side of the protective block.

[0015] The above-mentioned structural setting is used to dissipate heat generated by the continuous operation of the motor. By fixing the protective block at the end of the connecting column, a stable and secure environment is created for the motor inside the protective block.

[0016] Preferably, the fan blade device includes a movable sleeve and a frame. The movable sleeve is movably mounted on the outer ring of the horizontal axis. Redundant holes are opened at the bottom of the movable sleeve. The top and bottom surfaces of the movable sleeve are fixedly mounted with frames, and the blades are symmetrically and movably mounted between the frames.

[0017] With the above-mentioned structural setting, since the movable sleeve can rotate on the outer ring of the horizontal axis, the vibration effect of the blades and other components caused by the rotation of the shaft can be offset, and the vibration can be reduced or eliminated through the cooperation of this structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The aerial remote sensing mapping UAV is easy to disassemble and assemble by providing a fixing sleeve, a connecting column, an outer connecting sleeve and other structures. The outer connecting sleeve is rotated in the opposite direction to release the threaded sleeve connection with the thread groove A on the outer ring of the inner sleeve, so that the reinforced connection between the connecting column and the fixing sleeve is released. The connecting column is located on the outer ring of the outer sleeve and is rotated in the opposite direction to contact the threaded connection between the inner sleeve and the outer sleeve, so that the connecting column, the protective block and the fan blade device are separated from the outer ring of the UAV body. New components are taken out and installed by reversing the above steps, which makes disassembly and replacement easy.

[0020] 2. The aerial remote sensing mapping UAV achieves a shock absorption effect by setting up structures such as protective blocks and fan blade devices. The output shaft of the motor drives the rotating shaft and the transverse axis to rotate coaxially, and the transverse axis drives the fan blade device to rotate synchronously. Since the movable sleeve can rotate on the outer ring of the transverse axis, in order to facilitate the rotation of the movable sleeve on the outer ring of the transverse axis, a redundant hole is opened at the position of the rotating shaft, leaving enough redundant space during rotation, which can offset the vibration effect of the rotating shaft on components such as the blades. The structure cooperates to reduce or eliminate vibration. At the same time, the movable sleeve will not affect the rotation of the blades while rotating on the outer ring of the transverse axis, thereby achieving a shock absorption effect.

[0030] The above-mentioned structural setting realizes the modular design of the fan blade device components. When the structure is repaired or replaced after use, it can be quickly disassembled and assembled, thereby improving maintenance efficiency and operational flexibility. It not only improves maintenance efficiency, but also can quickly adjust the UAV configuration according to mission requirements. Through the internal setting of the fan blade device, the dynamic vibration of the fuselage can be reduced when the blades rotate, thereby reducing the vibration of the fuselage caused by the rotation of the blades.

[0031] See also Figure 1-Figure 4 The fixed sleeve 2 includes an inner sleeve 21 and an outer sleeve 22. The outer sleeve 22 is located in the inner ring of the inner sleeve 21. The inner sleeve 21 and the outer sleeve 22 are fixedly connected. The outer ring of the inner sleeve 21 is provided with a thread groove A, and the outer ring of the outer sleeve 22 is provided with a thread groove B. The outer sleeve 22 has symmetrical adaptation grooves on one side.

[0032] By setting the thread groove A and the thread groove B, quick assembly with the connecting column 3 and the outer connecting sleeve 4 is achieved. The connecting column 3 is threadedly sleeved with the outer sleeve 22, and the outer connecting sleeve 4 is threadedly sleeved with the inner sleeve 21. The connecting column 3 is fixed to the position of the outer ring of the fixed sleeve 2 through the above-mentioned threaded connection, and it is convenient to work during disassembly and assembly.

[0033] See also Figure 1-Figure 4 A plug connector 31 is rotatably installed inside the connecting column 3, and a connector head adapted to the adapting groove is symmetrically fixedly installed on one side of the plug connector 31. The connecting column 3 is located on the outer ring of the outer sleeve 22 and is provided with an inner sleeve 32. The inner sleeve 32 is fixedly connected to the connecting column 3, and the inner ring of the inner sleeve 32 is provided with a thread B, which is adapted to the thread groove B.

[0034] By setting the plug connector 31 and the internal sleeve 32, the connecting column 3 is initially limited on the side of the drone body 1, and at the same time a connection effect is achieved. The user can choose to realize intelligent control of the protective block 5 and the fan blade device 6 through the plug connector 31. After the internal sleeve 32 is connected to the outer sleeve 22, the position is preliminarily fixed.

[0035] See also Figure 1-Figure 4 The outer connecting sleeve 4 is located at the outer ring of the connecting column 3, and the outer connecting sleeve 4 is slidably installed on the outer ring of the connecting column 3. The outer ring of the inner sleeve 32 is provided with a block, and the outer connecting sleeve 4 cannot slide out of the outer ring of the connecting column 3. The block is a limit block of the outer connecting sleeve 4. The inner ring of the outer connecting sleeve 4 is provided with a thread A, and the thread A is adapted to the thread groove A. By sliding the outer connecting sleeve 4 to the end of the outer ring of the connecting column 3, it is threadedly connected to the outer ring of the inner sleeve 21, which plays a role in limiting and fixing the position of the connecting column 3 while connecting. This structural cooperation can further limit the position of the connecting column 3 and strengthen the connection between the connecting column 3 and the fixed sleeve 2.

[0036] See also Figure 1-Figure 5 A motor is provided inside the protective block 5. The end of the output shaft of the motor is located at the top of the protective block 5 and is fixedly connected to a rotating shaft 51. A horizontal axis 52 is provided on the top of the rotating shaft 51. The angle between the horizontal axis 52 and the rotating shaft 51 is a vertical angle. A heat sink 53 is provided on one side of the protective block 5 to dissipate the heat generated by the continuous operation of the motor. By fixing the protective block 5 at the end of the connecting column 3, a stable and secure environment is created for the motor inside the protective block 5. When the motor starts, it can drive the rotating shaft 51 to rotate synchronously with the output shaft, and the horizontal axis 52 will rotate synchronously with the rotating shaft 51.

[0037] See also Figures 1-6The fan device 6 includes a movable sleeve 61 and a frame 62. The movable sleeve 61 is movably installed on the outer ring of the horizontal shaft 52. A redundant hole 611 is opened at the bottom of the movable sleeve 61. The redundant hole 611 is a redundant space left for the rotating shaft 51 when the movable sleeve 61 rotates on the outer ring of the horizontal shaft 52, so that the movable sleeve 61 has enough space to rotate. The top and bottom surfaces of the movable sleeve 61 are fixedly installed with the frame 62, and the blades 63 are symmetrically and movably installed between the frames 62.

[0038] In the prior art, the propeller blades 63 are fixedly connected to the shaft 51, and the shaft 51 only drives the propeller blades 63 to continuously rotate horizontally. The vibration of the drone body caused by the rotation of the shaft 51 drives the precision components inside the drone body 1 to vibrate continuously. Since the parts are precisely installed, parts may fall off or become disconnected during the continuous vibration, causing chronic damage to the drone.

[0039] By setting the movable sleeve 61 to be movably installed on the outer ring of the horizontal shaft 52, after the motor is started, the output shaft drives the rotating shaft 51 to rotate in the chassis, and at the same time drives the horizontal shaft 52 and the movable sleeve 61 on the outer ring to rotate simultaneously, and drives the blades 63 to start rotating. Since the movable sleeve 61 can rotate on the outer ring of the horizontal shaft 52, the vibration effect of the blades 63 and other components caused by the rotation of the rotating shaft 51 can be offset. Through this structure, the vibration is reduced or eliminated. At the same time, the movable sleeve 61 will not affect the rotation of the blades 63 when it rotates on the outer ring of the horizontal shaft 52.

[0040] Working principle: After the device is assembled and unfolded as a whole, it is placed on the ground. The bracket 14 will provide support for the device and at the same time start the motor inside the protective block 5. The output shaft of the motor drives the rotating shaft 51 and the horizontal shaft 52 to rotate coaxially. The horizontal shaft 52 will drive the blade device 6 to rotate synchronously. Since the movable sleeve 61 can rotate on the outer ring of the horizontal shaft 52, in order to facilitate the rotation of the movable sleeve 61 on the outer ring of the horizontal shaft 52, a redundant hole 611 is opened at the position of the rotating shaft 51, leaving enough redundant space for rotation, which can offset the vibration effect of the rotating shaft 51 on the blades 63 and other components. The vibration is reduced or eliminated through the cooperation of this structure. At the same time, the movable sleeve 61 will not affect the rotation of the blades 63 when it rotates on the outer ring of the horizontal shaft 52.

[0041] When the fan blade device 6 or the protective block 5 and the connecting column 3 and other components have reached their service life or are damaged and need to be replaced, the outer connecting sleeve 4 is rotated in the opposite direction to release the threaded sleeve connection with the threaded groove A of the outer ring of the inner sleeve 21, so that the reinforced connection between the connecting column 3 and the fixed sleeve 2 is released, and the connecting column 3 located on the outer ring of the outer sleeve 22 is rotated in the opposite direction to contact the threaded connection between the inner sleeve 32 and the outer sleeve 22, so that the connecting column 3 and the protective block 5 and the fan blade device 6 are separated from the outer ring of the drone body 1, and new components are taken out. The new components can be installed by reversing the above steps, thereby achieving the effect of easy disassembly and replacement.
