[0024] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] Please refer to Figures 1 to 6 A total station turning point measuring device 1 is provided, including a base 13. The bottom of the base 13 is provided with a leveling component, and the top of the base 13 is provided with a high-strength rubber positioning tube 111. The high-strength rubber positioning tube 111 is provided with a prism rod slot 1111 along the axis, and the bottom center of the prism rod slot 1111 is provided with a crosshair positioning groove.

[0026] As described above, a total station point-shifting measuring device 1, through the cooperation of the prism rod slot 1111 and the prism rod 2, improves the efficiency of aligning the prism rod 2 with the crosshairs and enhances the stability of the prism rod 2 during operation. It features a simple structure and low cost. In use, the operator places the total station point-shifting measuring device 1 on the ground and adjusts it to a horizontal position using the leveling components at the bottom. Then, the prism rod 2 of the total station 3 is inserted into the prism rod slot 1111, with the crosshairs and slot aligned on the same axis. No manual calibration or positioning is required, making it more convenient and efficient. Simultaneously, the prism rod 2 is fixed by the high-strength rubber positioning tube 111, preventing displacement due to accidental manual contact and ensuring measurement accuracy.

[0027] Furthermore, the base 13 is provided with a support rib 112 for supporting the high-strength rubber positioning tube 111.

[0028] As described above, the support rib 112 supports the high-strength rubber positioning tube 111 to prevent the high-strength rubber positioning tube 111 from bending and shifting, which would indirectly affect the measurement accuracy.

[0029] Furthermore, the supporting rib plate 112 is a high-strength rubber reinforcing rib, and the high-strength rubber reinforcing rib has a hollow portion.

[0030] As described above, the reinforcing ribs have hollowed-out sections. Under the premise of ensuring structural strength, the use of hollowed-out reinforcing ribs results in low weight and easy portability.

[0031] Furthermore, the high-strength rubber positioning tube 111 is welded to the supporting rib plate 112.

[0032] As described above, the high-strength rubber positioning tube 111 is welded to the supporting stiffener 112, making it more robust and stable, less prone to deformation, and increasing the service life of the device.

[0033] Furthermore, a bubble level 1311 is provided on the base 13.

[0034] As described above, the bubble level 1311 is used to measure levelness. It is important to avoid device tilting, which could indirectly affect measurement accuracy.

[0035] Furthermore, the opening of the prism rod slot 1111 has a chamfer.

[0036] As described above, the opening of the prism rod slot 1111 has a chamfer, which facilitates the insertion of the prism rod 2 and improves work efficiency.

[0037] Furthermore, the leveling assembly includes two or more adjustable legs 133 disposed at the bottom of the base 13.

[0038] As described above, the adjustable support leg 133 is used to adjust the levelness of the device to ensure that the device is in a horizontal state.

[0039] Furthermore, the bottom of the support leg 133 is provided with a rubber pad 1331.

[0040] As described above, the rubber pad 1331 at the bottom of the support leg 133 is used to increase the friction between the support leg 133 and the bottom surface, so as to prevent the device from shifting and affecting the measurement.

[0041] Furthermore, the base 13 is circular, and the high-strength rubber positioning tube 111 is located at the center of the circle.

[0042] As described above, the base 13 is circular, and the high-strength rubber positioning tube 111 is located at the center of the circle, resulting in a more uniform mass distribution of the device and improved stability.

[0043] Furthermore, the prism rod slot 1111 is clearance-fitted with the prism rod 2.

[0044] As described above, the prism rod slot 1111 and the prism rod 2 are fitted with a clearance fit. The prism rod slot 1111 can better fix the prism rod 2 and prevent the prism rod 2 from shifting and affecting the measurement accuracy.

[0045] Please refer to Figures 3 to 4 Embodiment 1 of this utility model is as follows:

[0046] A total station pivot point measuring device 1 is provided, comprising a circular base 13. The bottom of the base 13 has a leveling assembly consisting of four telescopic legs 133, each leg 133 being threaded for extension and retraction. Each leg 133 has a rubber pad 1331 at its bottom. A high-strength rubber positioning tube 111 is vertically positioned at the top center of the base 13. The base 13 is supported and fixed to the high-strength rubber positioning tube 111 by three evenly distributed support ribs 112. The support ribs 112 are triangular and are high-strength rubber reinforcing ribs with hollowed-out portions. A prism rod slot 1111 is provided along the axis of the high-strength rubber positioning tube 111. The slot has a circular cross-section, and its diameter is the same as the cross-sectional diameter of the prism rod 2. A crosshair positioning groove is provided at the center of the slot's bottom. Further, a bubble level 1311 is provided on the base 13. Further, the opening of the prism rod slot 1111 has a 45-degree chamfer.

[0047] For detailed implementation procedures, please refer to: Figures 1 to 4 The total station turning point measuring device 1 of Embodiment 1 is placed at an arbitrary turning point position. The height of each support leg 133 is adjusted to ensure the device is level. The level can be determined using a bubble level 1311. Then, the prism rod 2 is directly inserted into the high-strength rubber positioning tube 111. The coordinates of the turning point are then measured using a total station 3 set up at the reference point. The position of the total station turning point measuring device 1 is then kept still, and the total station is set up at the turning point position using a tripod 4. During setup, the centering laser of the total station 3 must illuminate the crosshairs at the tip of the conical hollow cylinder of the device. The measured coordinates of the turning point and the reference point are then input into the total station 3 to establish a free coordinate system, thereby achieving the migration from the reference point to the turning point position.

[0048] Please refer to Figures 5 to 6 Embodiment two of this utility model is as follows:

[0049] The total station measuring device 1 includes a fixed support structure 11, a solar panel 12, and a base 13. The fixed support structure 11 is constructed by welding together a high-strength rubber positioning tube 111 and three supporting ribs 112. The base 13 includes a circular fixed disk 131, a central control system 132, and four support legs 133. The support legs 133 are hydraulic support legs. In this embodiment, the high-strength rubber positioning tube 111 is a thin-walled tube, with a prism rod 2 directly inserted in the middle, and a laser-engraved crosshair at its tip. The supporting ribs 112 are hollowed out in the middle to reduce structural weight. Both the high-strength rubber positioning tube 111 and the supporting ribs 112 are made of high-strength rubber material. In this embodiment, the solar panel 12 provides power to the central control system 132 and the support legs 133. A bubble level 1311 is mounted on the upper surface of the circular fixed disk 131. The bubble level 1311 is embedded in the circular fixed disk 131. The circular fixed disk 131 is molded from high-strength rubber material. In this embodiment, the central control system 132 is located inside the circular fixed disk 131. The central control system 132 has a built-in system program that can intelligently control the retraction of each support leg 133 via wireless remote control with one button, ensuring that the bubble level 1311 is centered. In this embodiment, the support leg 133 has a built-in intelligent hydraulic device that intelligently adjusts the height of the support leg by receiving instructions from the central control system 132, so as to meet the automatic leveling adjustment for different flat surfaces. In this embodiment, the fixed bracket structure 11, the solar panel 12, and the base 13 are connected to each other as a whole by adhesive bonding.

[0050] For detailed implementation procedures, please refer to: Figure 1 , Figure 2 , Figure 5 and Figure 6The total station turning point measuring device 1 is placed at an arbitrary turning point position. Using the remote control to operate the central control system 132, the height of each support leg 133 is adjusted with a single button, allowing the device to quickly level itself. Leveling can be determined by checking the centering of the bubble level 1311. Then, the prism rod 2 is placed directly into the high-strength rubber positioning tube 111 of the total station turning point measuring device 1. The coordinates of the turning point are then measured using the total station 3, which is mounted on the reference point. Keeping the total station turning point measuring device 1 stationary, the total station 3 is then mounted on the turning point position using a tripod 4. During the mounting of the total station 3, it is essential to ensure that the centering laser of the total station 3 illuminates the crosshairs at the tip of the high-strength rubber positioning tube 111. The measured coordinates of the turning point and the reference point are then input into the total station 3 to establish a free coordinate system, thus achieving the migration from the reference point to the turning point position. In this embodiment, one-button intelligent leveling is adopted via wireless remote control, which is efficient and accurate. The intelligent control program and the connection control relationship between the components are conventional technologies that can be obtained directly rather than being an improvement of this utility model, so they will not be described again.

[0051] In summary, a total station point-shifting measuring device improves the efficiency of aligning the prism rod with the crosshairs by using a prism rod slot and prism rod in conjunction, enhancing the stability of the prism rod during operation. It features a simple structure and low cost. In use, the operator places the total station point-shifting measuring device on the ground and adjusts it to a horizontal position using the leveling components at the bottom. Then, the prism rod of the total station is inserted into the prism rod slot, with the crosshairs and slot aligned on the same axis; no manual calibration or positioning is required, making it more convenient and efficient. Simultaneously, the prism rod is fixed by a high-strength rubber positioning tube, preventing displacement due to accidental manual contact and ensuring measurement accuracy. Furthermore, the supporting ribs support the high-strength rubber positioning tube, preventing bending and displacement that could indirectly affect measurement accuracy. Furthermore, the supporting ribs have hollow sections, ensuring structural strength while maintaining low weight and easy portability. Furthermore, the high-strength rubber positioning tube is welded to the supporting ribs, resulting in greater strength and stability, reducing deformation and increasing the device's lifespan. Finally, a bubble level is used to measure levelness. To prevent the device from tilting and indirectly affecting measurement accuracy, the prism rod slot opening is chamfered to facilitate prism rod insertion and improve work efficiency. Adjustable legs are used to adjust the device's level, ensuring it remains horizontal. Rubber pads at the bottom of the legs increase friction between the legs and the base, preventing device displacement and measurement errors. The circular base with a high-strength rubber positioning tube at the center results in more uniform mass distribution and improved stability. Furthermore, the prism rod slot and prism rod are fitted with a clearance fit, allowing for better prism rod fixation and preventing displacement that could affect measurement accuracy.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
