Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV used for high-altitude surveying. Background Technology

[0002] Unmanned aerial vehicles (UAVs) used for high-altitude surveys are specialized aircraft designed for operation in harsh mountainous environments characterized by thin air, low temperatures, and strong winds. They typically possess powerful propulsion systems and optimized propellers to overcome insufficient lift; their batteries are insulated to prevent sudden power drops. By integrating high-precision GNSS navigation (such as RTK modules) and specialized aerial survey cameras or lidar, they can fly autonomously, accurately collect surface data, and ultimately generate high-precision 2D orthophotos and 3D models for mapping, resource exploration, and engineering planning, efficiently and safely completing survey tasks in remote, inaccessible areas.

[0003] The data collection units on drones are expensive and sensitive to the environment, which means that the data collection units need to be frequently disassembled for independent inspection, cleaning, calibration and storage. This is to avoid the accumulation of hidden dangers in harsh flight vibration and high-altitude environments, and to ensure the absolute accuracy of the data and the long-term reliability of the equipment. However, the existing drones have simple structures and generally use screws to collect the data collection units. Whether it is installation or disassembly, the steps are relatively complicated and inefficient. Utility Model Content

[0004] The purpose of this invention is to propose a drone for high-altitude surveying in order to solve the problem of cumbersome loading and unloading of data collection units.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drone for high-altitude surveying includes a drone body with wings and propellers on both the drone body and wings. A cover plate is detachably mounted on the drone body, and a battery pack is located inside the drone body below the cover plate. A data collection assembly is mounted on the drone body via a connecting component, and a mounting bracket is provided inside the connecting component. The cover plate has mounting holes adapted to the mounting bracket, and the lower end of the mounting bracket passes through the mounting holes. A shock-absorbing component is provided at the lower end of the mounting bracket to prevent excessive vibration of the data collection assembly.

[0006] As a further description of the above technical solution: the connecting component includes a fixed plate fixedly installed at the lower end of the data collection assembly, a gear rotatably mounted on the fixed plate, a toothed plate slidably connected to the fixed plate fixedly mounted on the fixed frame, the toothed plate meshing with the gear, a knob fixedly connected to the gear rotatably mounted on the lower end face of the fixed plate, and a limiting unit to prevent the gear from rotating is provided below the fixed plate.

[0007] As a further description of the above technical solution: the knob is provided with a non-slip groove.

[0008] As a further description of the above technical solution: the limiting unit includes a round rod slidably mounted on the knob, a horizontal plate fixedly mounted on the round rod, a first spring provided between the horizontal plate and the knob, and a round groove adapted to the round rod is opened on the lower end face of the fixed plate.

[0009] As a further description of the above technical solution: the shock absorption assembly includes a connecting frame, a damping rod is fixedly installed on the connecting frame, an elastic plate is fixedly installed at the end of the damping rod, and a second spring is provided between the damping rod and the connecting frame.

[0010] As a further description of the above technical solution: the wing includes a side wing and a tail wing, and the side wing and the tail wing are fixedly connected by a connecting rod.

[0011] As a further description of the above technical solution: the number of propellers located at the tail of the UAV is far less than the number of propellers between the wings.

[0012] As a further description of the above technical solution: the wing is made of carbon fiber composite material.

[0013] As a further description of the above technical solution: the elastic force of the first spring is much greater than the weight of the horizontal plate.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The knob drives the gear to rotate, and the gear meshes to drive the toothed plate to slide along the fixed plate. This causes a pair of toothed plates to drive a pair of fixed frames to move towards the center. The fixed frames clamp the outside of the battery pack through the shock-absorbing components. By rotating the knob in the opposite direction, the data collection assembly can be disassembled for inspection. Both installation and disassembly are quick and easy. The fixed frames clamp the outside of the battery pack through the shock-absorbing components, eliminating the need for direct installation on the drone shell. When the data collection assembly encounters unstable airflow at high altitudes, the vibration of the data collection assembly is transmitted to the battery pack and will not damage the drone shell. When the data acquisition assembly vibrates due to airflow, the damping rod and the second spring can absorb the energy generated by the vibration through their own deformation, preventing the data acquisition assembly from shaking violently.

[0017] 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.

[0018] Example: This example provides a drone for high-altitude surveying. See [link to example]. Figure 1 - Figure 5 Specifically, the drone includes a drone body 1, on which wings 11 are mounted, and propellers 12 are mounted on the drone body 1 and wings 11. A cover plate 13 is detachably mounted on the drone body 1. A battery pack 14 is located inside the drone body 1 below the cover plate 13. A data collection assembly 15 is mounted on the drone body 1 via a connecting component. A mounting bracket 22 is located inside the connecting component. The cover plate 13 has mounting holes 16 that are adapted to the mounting bracket 22. The lower end of the mounting bracket 22 passes through the mounting holes 16. A shock-absorbing component is provided at the lower end of the mounting bracket 22 to prevent excessive vibration of the data collection assembly 15. The connecting component includes a fixing plate 2 fixedly mounted at the lower end of the data collection assembly 15. A gear 21 is rotatably mounted on the fixing plate 2. A toothed plate 23 is fixedly mounted on the fixing bracket 22 and slidably connected to the fixing plate 2. The toothed plate 23 meshes with the gear 21. A knob 24 fixedly connected to the gear 21 is rotatably mounted on the lower end face of the fixing plate 2. A limiting unit is provided below the fixing plate 2 to prevent the gear 21 from rotating. Place the data collection assembly 15 above the cover plate 13, rotate the knob 24, the knob 24 drives the gear 21 to rotate, the gear 21 drives the toothed plate 23 to slide along the fixed plate 2 through meshing, the pair of toothed plates 23 move in opposite directions, thus causing the pair of toothed plates 23 to drive the pair of fixed brackets 22 to move towards the middle, the lower end of the fixed bracket 22 passes through the mounting hole 16 and enters the inside of the cover plate 13, the fixed bracket 22 clamps the outside of the battery pack 14 through the shock absorption component, abandoning the method of directly installing on the drone shell, when the data collection assembly 15 encounters unstable airflow at high altitude, the oscillation of the data collection assembly 15 is transmitted to the battery pack 14, and will not cause damage to the drone shell. Since the battery pack 14 has a large mass, the data collection assembly 15 can be fixed more stably. Rotate the knob 24 in the opposite direction, and the data collection assembly 15 can be disassembled for inspection; The knob 24 has a non-slip groove. The elongated groove prevents slippage when turning the knob 24, facilitating the installation of the data collection assembly 15; The limiting unit includes a round rod 32 that is slidably mounted on the knob 24, a horizontal plate 3 that is fixedly mounted on the round rod 32, a first spring 31 that is provided between the horizontal plate 3 and the knob 24, and a round groove 33 that is adapted to the round rod 32 is provided on the lower end face of the fixed plate 2. Before turning the knob 24, pull the horizontal plate 3 down until the round rod 32 disengages from the round groove 33. After installation, release the horizontal plate 3. The first spring 31 drives the horizontal plate 3 back to its original position. During this process, the horizontal plate 3 drives the round rod 32 to insert into the corresponding round groove 33, so that the position of the knob 24 will not deflect again, thereby ensuring that the position of the fixing frame 22 will not change, ensuring the stability of the clamping, and preventing loosening during the operation of the drone. The shock absorption assembly includes a connecting frame 4, a damping rod 41 fixedly installed on the connecting frame 4, an elastic plate 42 fixedly installed at the end of the damping rod 41, and a second spring 43 provided between the damping rod 41 and the connecting frame 4. When the data collection assembly 15 vibrates due to airflow, the damping rod 41 and the second spring 43 can absorb the energy generated by the vibration through their own deformation, preventing the data collection assembly 15 from shaking violently. The elastic plate 42 has a certain degree of extensibility to prevent damage to the battery pack 14 casing during the installation of the data collection assembly 15. The wing 11 includes a side wing and a tail wing, and the side wing and tail wing are fixedly connected by a connecting rod; The connection between the side wings and the tail fin improves the overall structural rigidity of the drone, enabling it to cope more easily with unstable airflow at high altitudes and enhancing the safety of the device. The number of propellers 12 located at the tail of the UAV body 1 is far less than the number of propellers 12 between the wings 11; The propellers 12 between the wings 11 are used to climb the altitude, and the propellers 12 at the tail of the drone body 1 are used to propel the drone forward. The presence of more propellers 12 between the wings 11 gives the drone a strong climbing ability, enabling it to easily perform high-altitude operations. Wing 11 is made of carbon fiber composite material; Carbon fiber has a density only 1 / 3 that of aluminum, but its tensile strength is close to or even exceeds that of steel, and its specific strength is several times that of high-grade alloy steel. Carbon fiber composites can withstand extreme temperatures (-40℃ to 50℃), reduce structural deformation caused by temperature changes, and can adapt well to low-temperature environments at high altitudes. The elastic force of the first spring 31 is much greater than the weight of the horizontal plate 3; During normal use of the drone, the first spring 31 can firmly restrict the round rod 32 within the round groove 33 through the cross plate 3, preventing the internal structure of the drone from becoming loose.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
