Description

Technical Field

[0001] The utility model relates to a support base, in particular to a support base of an RTK base station. Background Art

[0002] The operating principle of RTK surveying instruments is based on real-time dynamic differential GPS technology, achieving high-precision positioning through data transmission and processing between a base station and a rover. However, before each measurement, point calibration of known control points is required to complete station orientation. The coordinate values of the base station serve as the foundation for differential corrections throughout the entire survey area, and their accuracy directly determines the measurement accuracy of all stations within the survey area. Therefore, the location selection of the base station and the accuracy of the control point coordinates are very important in RTK measurement. To ensure that the receiver bubble is centered and the error is minimized during point calibration, existing control point coordinate calibration is generally performed manually or with the assistance of a tripod. The location selection is relatively simple and arbitrary, usually on a raised stone or concrete pavement. Although this meets the requirements for the location and spatial distance from the base station, it is easily affected by external factors, which seriously affects the calibration results. Utility Model Content

[0003] In response to the above problems, the present invention provides a support base for an RTK base station, which effectively improves the coordinate accuracy of the reference station, solves the problem of the control point coordinates being affected by external factors, and at the same time improves the support stability of the RTK base station and improves measurement accuracy.

[0004] In order to achieve the above-mentioned purpose, the support base of the RTK base station of the present invention includes a base and a metal column located on the upper surface of the base. A spherical groove is provided at the center position of the upper end surface of the metal column, and the spherical groove abuts against the lower end of the RTK base station. An annular groove is provided on the upper surface of the base, and the annular groove is arranged outside the metal column.

[0005] Furthermore, the fixing device includes an annular clamp and several support members located inside the annular clamp. The annular clamp is embedded in the annular groove. The annular clamp is provided with a vertical positioning groove. The number of positioning grooves is the same as that of the support member. A threaded column is fixed on the back of the support member. The outer end of the threaded column passes through the corresponding positioning groove and is threadedly connected to a nut.

[0006] Furthermore, the number of the support members and the positioning grooves is three, the transverse cross-section of the support member is arc-shaped, and the three support members are arranged in a circular manner on the inner wall of the annular clamp.

[0007] Furthermore, a fixing strip is longitudinally provided on the inner wall of the support member, a card groove is longitudinally provided on the two side surfaces of the fixing strip, a positioning member is provided on the outer periphery of the fixing strip, the positioning member includes two parallel mounting plates and an arc-shaped member fixedly connected to the outer end surface of the mounting plate, and a slider is provided on the inner side surface of the mounting plate, and the slider is located in the card groove.

[0008] Furthermore, the arc-shaped member is made of elastic material, and the two side directions of the fixing strip with the slots are defined as the width of the fixing strip. The fixing strip is a structure with a width that gradually increases from bottom to top.

[0009] Furthermore, there is a damping effect between the slider and the slot.

[0035] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] like Figure 1 and Figure 2 As shown, it is a partial structural diagram of the support base of the RTK base station of the present invention and a cross-sectional diagram of the base 10. The support base of the present invention is provided with a base 10 and a metal column 20 located on the upper surface of the base 10. The base 10 can be a base made of concrete. The metal column 20 is embedded in the center position of the base 10 (such as Figure 2 As shown), a spherical groove 30 is provided at the center of the upper end surface of the metal column 20, and the spherical groove 30 abuts against the lower end of the RTK base station data sensor, and an annular groove 40 is provided on the upper surface of the base 10, as shown Figure 1As shown, the annular groove 40 is a relatively narrow, deep annular groove structure, and is disposed around the metal column 20. During use, the support base of this embodiment does not require any other brackets or fixing structures. The lower end of the data sensor is placed on the metal column 20, and the spherical groove 30 on the metal column 20 precisely aligns with the lower end of the data sensor, facilitating quick and stable point calibration. Furthermore, the surveyor stands with both feet on the upper surface of the base 10, and the sensor and the surveyor's legs form a stable triangular support. Utilizing the principle of high stability of the triangle, the point calibration accuracy is more accurate, reducing human error.

[0037] See also Figure 3 and Figure 4 As shown, the present invention also includes other embodiments, in which a fixing device is further provided in the annular groove 40, and the fixing device is used to fix the sensor of the RTK base station more stably on the base 10, specifically, as shown in FIG. Figure 3 As shown, the fixing device is provided with an annular clamp 50 and several support members 60 located in the annular clamp 50. In this embodiment, the transverse cross-section of the support member 60 is arc-shaped, and the number of the support members 60 is three. The three support members 60 are arranged in a circular manner on the inner wall of the annular clamp 50, and the annular clamp 50 is stably embedded and engaged in the annular groove 40. The depth of the annular groove 40 can completely prevent the annular clamp 50 from tipping over. A vertical positioning groove 51 is provided on the annular clamp 50. The number of the positioning grooves 51 is the same as that of the support member 60. In this embodiment, the number of the positioning grooves 51 is also three. A threaded column 52 is fixed on the back of the support member 60. The outer end of the threaded column 52 passes through its corresponding positioning groove 51 and is screwed to a nut 53, thereby stably fixing the support member 60 inside the annular clamp 50. At the same time, the position of the threaded column 52 can be adjusted at any time in the positioning groove 51, thereby adjusting the height and position of the support member 60 to adapt to different height requirements.

[0038] Please refer to Figure 3 and Figure 4 As shown, the inner wall of the support member 60 of the present invention is provided with a fixing strip 61 in the longitudinal direction, and the two sides of the fixing strip 61 are provided with a card slot 62 in the longitudinal direction. The two side directions of the fixing strip 61 with the card slot 62 are defined as the width of the fixing strip 61. The fixing strip 61 is a structure with a width gradually increasing from bottom to top (such as Figure 5 As shown), a positioning member 70 is provided on the outer periphery of the fixing bar 61. The positioning member 70 includes two parallel mounting plates 71 and an arc-shaped member 72 fixedly connected to the outer end surface of the mounting plate 71. The arc-shaped member 72 is made of an elastic material and has a certain elasticity and can be deformed. A slider (not shown in the figure) is fixedly provided on the inner side surface of the mounting plate 71. The slider is located in the slot 62, and there is a damping effect between the slider and the slot 62.

[0039] During use of the support base of the present invention, after the sensor is placed on the metal column 20, if some special circumstances occur and manual fixation is not possible and automatic fixation is required, the position of the positioning member 70 can be adjusted and moved from bottom to top. Since the width of the fixing bar 61 gradually increases from bottom to top, all the positioning members 70 gradually move closer to the middle, and finally the RTK base station sensor is fixed. Since the base 10 has a certain weight, once the RTK base station sensor is stably fixed, the base 10 can completely prevent the sensor from tipping over.

[0040] Through the above technical solution, the support base of the RTK base station of the utility model is provided with a base 10, and a spherical groove 30 is provided on the metal column 20 on the base 10, which coincides with the lower end of the data sensor. The base 10 replaces the complex external environment of the RTK base station in the prior art, thereby improving the accuracy; in addition, the utility model is also provided with a fixing device, which can further stably fix the RTK base station, and the fixing device is flexible to be disassembled and assembled. When no external tools are needed, the fixing device can be taken out, and when it is needed, it can be directly installed on the base 10; furthermore, the support base of the utility model does not use easily damaged parts such as electric devices or springs, so the RTK base station can be well fixed for use, and it is simple to operate and easy to transport, and has a high value of popularization and application.

[0041] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
