[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a surveying and mapping device based on a drone, such as Figure 1-4As shown, the UAV-based surveying and mapping equipment includes: a UAV body 1; a fixing member 6, the fixing member 6 is installed at the bottom of the UAV body 1; an adjusting member 7, the adjusting member 7 is installed at the bottom of the fixing member 6, and the adjusting member 7 is used to adjust the surveying and mapping direction; a mounting plate 2, the mounting plate 2 is installed at the bottom of the adjusting member 7; a stabilizer 3, the stabilizer 3 is arranged on the top of the mounting plate 2, and the stabilizer 3 is used to maintain stable surveying and mapping; a surveying and mapping instrument body 4, the surveying and mapping instrument body 4 is installed on the stabilizer 3, and the surveying and mapping instrument body 4 is used for geographic surveying and mapping.

[0022] In this embodiment, the drone body 1 serves as the carrier of the entire surveying and mapping system. The drone body 1 is responsible for flying in the changeable terrain and environment in the wild, providing a mobile platform for surveying and mapping tasks. The fixing part 6 serves as a bridge connecting the drone and the surveying and mapping equipment below. The design of the adjustment part 7 allows the user to flexibly adjust the direction of the surveying and mapping equipment. In complex surveying and mapping tasks, the orientation of the surveying and mapping instrument can be adjusted quickly and accurately to improve the surveying and mapping accuracy and efficiency. The stabilizer 3 is used to maintain stability during the surveying and mapping process. The drone body 1 will inevitably encounter adverse factors such as airflow disturbances and wind direction changes during flight. The stabilizer 3 can effectively offset these external interferences and ensure that the data obtained by the surveying and mapping instrument body 4 is accurate, which is crucial to improving the surveying and mapping accuracy and ensuring the quality of the surveying and mapping results. The surveying and mapping instrument body 4 uses advanced sensors and data processing technology to efficiently and accurately obtain information such as ground terrain, landforms, and elevation, providing an important basis for subsequent geographic analysis, planning decisions, etc.

[0023] In a further preferred embodiment of the utility model, the fixing member 6 includes a limit block 8, a limit shell 9, two springs 10 and two clamping blocks 11, the limit block 8 is fixed to the bottom of the drone body 1, the limit shell 9 is sleeved outside the limit block 8, the two springs 10 are both installed in the limit shell 9, the two springs 10 are respectively located on both sides of the limit block 8, the two clamping blocks 11 are respectively fixed on the side where the two springs 10 are close to each other, and the two clamping blocks 11 can extend into the limit block 8.

[0024] In this embodiment, the limit block 8 serves as the basis for installation and positioning. The introduction of the spring 10 enables the block 11 to produce a certain elastic deformation when subjected to external force, thereby facilitating the installation and disassembly of the surveying and mapping equipment. At the same time, the reset force of the spring 10 ensures that the block 11 can be tightly clamped in the limit block 8 when not subjected to external force, thereby ensuring the stability of the connection. The block 11 is a key component for achieving rapid installation and disassembly. When installing the surveying and mapping equipment, the block 11 is pushed to compress the spring 10, and then the surveying and mapping equipment is placed in and the block 11 is released. The reset force of the spring 10 is used to clamp the block 11 into the limit block 8, thereby achieving a rapid and stable connection. When disassembling, the reverse operation can be performed.

[0025] In a further preferred embodiment of the utility model, the adjusting member 7 includes a cylinder 17, a limit plate 18, a limit cylinder 19, a base 20, a motor 21, a reducer 22 and a connecting rod 23, the cylinder 17 is fixed to the bottom of the limit shell 9, the limit plate 18 is installed on the cylinder 17, the limit cylinder 19 is rotatably sleeved outside the cylinder 17, the base 20 is fixed to the bottom of the limit cylinder 19, the motor 21 and the reducer 22 are both installed in the cylinder 17, the reducer 22 is connected to the output shaft of the motor 21, the connecting rod 23 is installed on the output shaft of the reducer 22 and is fixedly connected to the base 20, and the mounting plate 2 is fixed to the bottom of the base 20.

[0026] In this embodiment, the cylinder 17 provides a stable installation foundation for the entire adjusting member 7, and the limit plate 18 is used to limit the rotation range of the limit cylinder 19 and provide support at the same time. The existence of the limit plate 18 ensures the stability and safety of the adjusting member 7 during the adjustment process. The motor 21 provides a power source for the adjusting member 7. The introduction of the motor 21 and the reducer 22 enables the adjusting member 7 to achieve precise adjustment of the surveying and mapping equipment at a lower speed of the motor 21, thereby improving the accuracy and stability of the adjustment. The connecting rod 23 is a key component for transmitting power and realizing adjustment.

[0027] In a further preferred embodiment of the utility model, a plurality of balls are embedded on the top of the limiting plate 18, and the plurality of balls are in contact with the top inner wall of the limiting cylinder 19, and a plurality of supporting legs 5 are installed on the bottom of the drone body 1.

[0028] In this embodiment, the introduction of the ball realizes rolling contact between the limit plate 18 and the limit cylinder 19 instead of traditional sliding contact. The rolling contact significantly reduces the friction resistance between the limit plate 18 and the limit cylinder 19, making the limit cylinder 19 smoother and more labor-saving when rotating and adjusting. This not only improves the flexibility and response speed of the adjustment, but also reduces the wear and heat generated by friction, thereby extending the service life of the equipment. The support legs 5 provide additional support and stability when the drone body 1 lands or parks, thereby preventing the surveying and mapping equipment from contacting the ground and causing damage or affecting the surveying and mapping accuracy.

[0029] In a further preferred embodiment of the utility model, a plurality of connecting tubes 14 are detachably mounted on the drone body 1, a plurality of supporting rods 15 are detachably mounted in the plurality of connecting tubes 14, and a propeller 16 is mounted on the plurality of supporting rods 15.

[0030] In this embodiment, the connecting tube 14 serves as the installation base for the support rod 15 and the propeller 16. Its detachability provides great convenience for the maintenance and upgrade of the UAV body 1. When the propeller 16 needs to be replaced or repaired, the propeller 16 can be easily removed by simply disassembling the connecting tube 14. There is no need to disassemble the entire UAV body 1. This not only saves time and labor costs, but also reduces the risk of damage that may be caused during the disassembly process. The propeller 16 is a key component for generating lift and thrust for the UAV.

[0031] In a further preferred embodiment of the utility model, a connecting rope 12 is fixed to each of the two clamping blocks 11 , and the two connecting ropes 12 extend to two sides of the limiting shell 9 respectively, and a pull ring 13 is fixed to each of the two connecting ropes 12 .

[0032] In this embodiment, the connecting rope 12 serves as a transmission element to connect the card block 11 with the external pull ring 13, so that the user can indirectly control the movement of the card block 11 by operating the pull ring 13. The introduction of the connecting rope 12 makes the operation of the card block 11 more convenient and safer. The user does not need to directly touch or contact the card block 11 and the spring 10 and other internal components. The card block 11 can be compressed and released by pulling the pull ring 13. This not only simplifies the operation process, but also reduces the risk of equipment damage due to misoperation.

[0033] In a further preferred embodiment of the utility model, rubber pads are installed at the bottom of the plurality of support legs 5, and two clamps are provided on the stabilizer 3. The two clamps are hinged to each other, and a torsion spring is installed between the two clamps. The clamps are used to clamp and stabilize the surveying instrument body 4.

[0034] In this embodiment, the introduction of the rubber pad makes the contact between the support leg 5 and the ground softer when the drone body 1 is landing or parking, reducing the impact and vibration caused by hard contact. This not only helps to protect the drone body 1 and the surveying and mapping equipment thereon from damage, but also improves the stability of the drone on uneven ground. The rubber pad can also increase the friction between the support leg 5 and the ground to prevent the drone from sliding or tipping over under the action of external forces such as wind. The design of the splint forms an openable and closable clamping mechanism, and the torsion spring is used to provide the clamping force.

[0035] In summary, compared with the related art, the present device can install the surveying instrument body 4 on the drone body 1 by setting the fixing part 6, and can adjust the surveying direction of the surveying instrument body 4 by setting the adjusting part 7. There is no need to adjust the orientation of the drone body 1, and more comprehensive surveying data can be obtained on a single surveying path. By setting the connecting tube 14 to connect the support rod 15, the propeller 16 and the drone body 1, the subsequent disassembly and maintenance of the propeller 16 is facilitated, and at the same time, the space occupied by the drone body 1 during storage is reduced.

[0036] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.
