[0002] The surveying device is a professional integrated surveying equipment that is suitable for all scenarios of field land surveys and integrates surveying operations and auxiliary operation functions. It can realize the core data collection of surveying operations and meet the professional use requirements of various land surveying and mapping work such as land ownership confirmation. It is a special surveying equipment for field land surveys that integrates surveying operations, on-site data processing, and accessory storage.

[0003] However, most existing surveying devices rely on a single power supply mode with built-in batteries, which can easily lead to power outages and shutdowns during field operations. Some devices equipped with solar charging structures often have fixed, integrated photovoltaic panels with limited light-receiving area and low light energy conversion efficiency. Furthermore, they lack flexible storage and deployment structures, leaving the photovoltaic panels directly exposed during idle periods or transport, making them susceptible to damage from impacts, dust, and sand. Additionally, the inability to adjust the position of the photovoltaic panels according to the angle of sunlight significantly reduces charging efficiency, making it difficult to provide continuous auxiliary power to the surveying instrument. This also prevents the precise adjustment of the instrument's operating height and rotation angle based on complex terrain and varying surveying perspectives, resulting in inaccurate data collection at some surveying points due to perspective deviations, further impacting the accuracy of the surveying data.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please refer to Figure 1 and Figure 2A surveying device for land surveying includes: a support base 1, a mounting base 3 on the top of the support base 1, a surveying instrument body 4 on the top of the mounting base 3, a wiping plate 8 on one side of the surveying instrument body 4, a plurality of adjustment knobs 7 installed between the mounting base 3 and the surveying instrument body 4, and a stabilizing component at the bottom of the support base 1.

[0021] Please refer to Figure 7 - Figure 9 The charging mechanism is located on the top of the surveying instrument body 4 and is used to assist in charging the surveying instrument body 4. The charging mechanism includes an installation chamber 13 installed on the top of the surveying instrument body 4 and a receiving cavity 24 opened inside the installation chamber 13. A guide solar panel 22 is provided inside the receiving cavity 24. Multiple extended solar panels 23 are provided at one end of the guide solar panel 22. A guide component is provided at one end of both the multiple extended solar panels 23 and the guide solar panel 22. The guide component includes a guide groove 28 opened at the bottom of the multiple extended solar panels 23 and the guide solar panel 22, and a guide groove opened inside the installation chamber 13. A guide plate 29 is fixedly installed at one end of the guide solar panel 22. The guide plate 29 is located inside the guide groove. A guide slide plate is fixedly installed at one end of each of the multiple extended solar panels 23. The guide slide plate is located inside the guide groove 28. A drive component is provided on the top of the installation chamber 13, and an angle adjustment mechanism is provided on the top of the support seat 1. When using this surveying device, first place the support base 1 at the surveying work point, unfold the stabilizing component at its bottom to fix the device, and then fine-tune the initial angle of the surveying instrument body 4 using the adjustment knob 7 on the mounting base 3 to position the surveying instrument body 4 in the basic surveying position. Then, the charging mechanism can be activated according to the power demand of outdoor surveying. First, the drive component at the top of the mounting chamber 13 drives the guide solar panel 22 to extend from the housing cavity 24. The guide plate 29 at the bottom of the guide solar panel 22 will slide along the guide groove inside the mounting chamber 13 to achieve stable guidance. Then, pull multiple extended solar panels 2 3. The guide slide plate at one end of the extended solar panel 23 will slide along the guide groove 28 at the bottom of the guide solar panel 22, allowing multiple extended solar panels 23 to unfold in sequence. After unfolding, the guide solar panel 22 and the extended solar panel 23 can receive light energy to assist in charging the surveying instrument body 4. During the operation of the charging mechanism and the surveying operation, the angle adjustment mechanism can be adjusted to allow the charging mechanism to better receive light energy and to adapt the surveying instrument body 4 to different surveying angle requirements. Throughout the process, the wiping plate 8 can clean the lens 10 of the surveying instrument body 4 at any time to ensure the accuracy of the surveying operation.

[0022] Furthermore, such as Figure 7 - Figure 10As shown, the drive assembly includes a drive motor 30 mounted on the top of the mounting chamber 13 and a transmission gear 25 rotatably mounted on the top of the mounting chamber 13. A mounting rod is provided at the bottom of the transmission gear 25, penetrating the mounting chamber 13 and located inside the receiving cavity 24. One end of each of the extended solar panels 23 and the guide solar panel 22 is mounted on the mounting rod. A semi-toothed plate 31 meshing with the transmission gear 25 is provided on one side of the main shaft of the drive motor 30. A protective cover 21 is installed on the top of the mounting chamber 13, and the drive motor 30, the semi-toothed plate 31, and the transmission gear 25 are all located inside the protective cover 21. Therefore, when using the charging mechanism of this surveying device, the drive motor 30 on the top of the mounting chamber 13 is first started. The drive motor 30 drives the semi-toothed plate 31 on one side of the main shaft to move. The semi-toothed plate 31 meshes with the transmission gear 25, causing the transmission gear 25 to rotate. When the transmission gear 25 rotates, it drives... The mounting rod at the bottom rotates synchronously, which drives the guide solar panel 22 and multiple extension solar panels 23 on its outer side to move synchronously. This enables the guide solar panel 22 to extend out of the receiving cavity 24 and the multiple extension solar panels 23 to unfold. During the entire driving process, the protective cover 21 encloses the drive motor 30, the half-tooth plate 31, and the transmission gear 25, preventing wind, sand, rain, and other impurities from corroding and damaging the drive components during outdoor operations. This ensures the stable operation of the drive components, allowing the guide solar panel 22 and the extension solar panels 23 to unfold smoothly and be adjusted to a suitable angle of light reception, continuously providing auxiliary power to the surveying instrument body 4. When power is not needed, the drive motor 30 is started in reverse. Through the meshing of the half-tooth plate 31 and the transmission gear 25, the mounting rod is driven to rotate in the opposite direction, which retracts the guide solar panel 22 and the extension solar panels 23 into the receiving cavity 24 for storage.

[0023] Furthermore, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the stabilizing component includes multiple support rods 5 hinged to the bottom of the support base 1 and fixed insert rods 18 installed at the bottom of the multiple support rods 5. Each support rod 5 has a sliding groove 26. An adjusting component is provided between the fixed insert rod 18 and the support rods 5. The adjusting component includes an adjusting bracket 6 fixedly installed on the top of the fixed insert rod 18 and an adjusting rod 17 disposed inside the adjusting bracket 6. The adjusting bracket 6 is slidably installed on the support rods 5, and the adjusting rod 17 is located inside the sliding groove 26. A fixing bolt 27 is provided at one end of the adjusting bracket 6, and one end of the adjusting rod 17 passes through the adjusting bracket 6. The fixing bolt 27 is screwed onto the adjusting rod 17. Therefore, when using the stabilizing component of this surveying device, first, the multiple support rods 5 hinged to the bottom of the support base 1 are extended outwards to form a stable support angle with the ground. Then, the fixed insert rod 18 is adjusted according to the ground terrain of the surveying operation. The height is adjusted so that the adjusting bracket 6 at the top of the fixed rod 18 slides along the support rod 5. The adjusting bracket 6 drives the internal adjusting rod 17 to move synchronously in the sliding groove 26 of the support rod 5. After the fixed rod 18 is adjusted to a suitable height that can be stably inserted into the ground, the fixing bolt 27 at one end of the adjusting bracket 6 is turned so that the fixing bolt 27 is screwed onto the adjusting rod 17 to complete the position locking. Then, multiple fixed rods 18 are forcefully inserted into the ground at the surveying point. The cooperation of multiple support rods 5 and fixed rods 18 forms multi-directional support, which firmly fixes the bearing seat 1 at the work point, preventing the device from shaking or shifting during the surveying process and ensuring the operational stability of the surveying instrument body 4. If it is necessary to change the surveying point, first loosen the fixing bolt 27 in the reverse direction, slide the adjusting bracket 6 up to retract the fixed rod 18, and then retract the support rod 5 towards the bearing seat 1 to complete the movement of the device.

[0024] Furthermore, such as Figure 1 - Figure 4As shown, a drive motor 2 9 is installed at one end of the surveying instrument body 4, a lens 10 is installed at the other end of the surveying instrument body 4, a wiping plate 8 is installed at one end of the lens 10, a linkage rod 11 is fixedly installed on one side of the wiping plate 8, and a protective mounting cover is installed on one side of the surveying instrument body 4. The drive motor 2 9 is located inside the protective mounting cover, and one end of the linkage rod 11 is connected to the main shaft of the drive motor 2 9. Based on this, when the surveying instrument body 4 is conducting land surveying operations, if dust or debris adheres to the surface of the lens 10 and affects the clarity of the surveying, the drive motor 2 9 at one end of the surveying instrument body 4 can be activated, and the protective mounting cover on one side of the surveying instrument body 4 can be activated. It can protect the drive motor 29 from damage caused by impurities during outdoor operations. The operation of the drive motor 29 will drive the linkage rod 11 connected to the main shaft to rotate. The linkage rod 11 will simultaneously drive the wiping plate 8 on one side to rotate. The wiping plate 8 will rotate and wipe the surface of the lens 10, which can quickly clean the dirt and dust on the surface of the lens 10. After wiping, the drive motor 29 will be turned off to stop the wiping plate 8 from rotating. The entire operation can be carried out at any time during the surveying operation without disassembling any parts. It can keep the cleanliness of the lens 10 in time, and keep the surveying instrument body 4 at all times with a clear surveying perspective, ensuring the accuracy of the land surveying data.

[0025] Please also refer to... Figure 1 , Figure 2 , Figure 11 and Figure 12The angle adjustment mechanism includes an adjustment seat 15 mounted on the top of the support 1 and an adjustment cavity opened inside the fixed rod 2. An extension rod 14 is mounted on the top of the fixed rod 2, and the bottom of the extension rod 14 is slidably mounted inside the adjustment cavity. The fixed rod 2 is hinged to the adjustment seat 15. Multiple fixing slots 32 are opened on one side of the extension rod 14. A limit insert rod 16 is provided on one side of the fixed rod 2. One end of the limit insert rod 16 passes through the fixed rod 2 and is inserted into the fixing slot 32. A rotating assembly is provided on the top of the support 1. The rotating assembly includes a semi-circular plate 12 mounted on the top of the support 1 and an installation chamber 13 opened on the semi-circular plate 12. One end of the fixed rod 2 is fixedly mounted on a sliding block, which is inside the installation chamber 13. A limit slide plate 19 is provided on one side of the semi-circular plate 12. A fastening bolt 20 is mounted on one end of the limit slide plate 19. One end of the fastening bolt 20 passes through the limit slide plate 19 and is screwed into the sliding block. Based on this, the angle adjustment mechanism of the surveying device is used... During setup, the position of the extension rod 14 can be adjusted according to the required surveying height. The extension rod 14 is then pulled up and down in the adjustment cavity inside the fixed rod 2. After adjusting to the appropriate height, one end of the limiting rod 16 is inserted through the fixed rod 2 into the fixing slot 32 on one side of the extension rod 14 to fix the height of the extension rod 14. If it is necessary to adjust the horizontal angle, the sliding block at one end of the fixed rod 2 can be pushed to slide inside the mounting chamber 13 on the semicircular plate 12. The sliding block drives the fixed rod 2 and the extension rod 14 to rotate synchronously in an arc. After adjusting the surveying instrument body 4 to the required angle, the fastening bolt 20 on the limiting slide plate 19 on one side of the semicircular plate 12 is tightened so that one end of the fastening bolt 20 passes through the limiting slide plate 19 and is screwed into the interior of the sliding block to lock the position of the sliding block. This ensures that the entire angle adjustment mechanism is firmly fixed and prevents angle deviation during the surveying process. The entire adjustment process can flexibly adjust the height and multi-directional angle of the surveying instrument body 4 to adapt to different surveying operation needs in the field.
