Description

Technical Field

[0001] The utility model relates to the field of satellite navigation, and in particular to a multi-scene rotatable GNSS observation pier. Background Art

[0002] BeiDou satellite navigation system is a satellite navigation system independently developed by China. It has the characteristics of global coverage, high precision and high reliability. Its application scenarios are very wide, covering transportation, agriculture, emergency rescue, positioning services, scientific research, public safety and other fields. With the advancement of the global application of BeiDou satellite navigation system, more and more industries are more dependent on high-precision positioning. Therefore, in order to further improve the positioning accuracy and reduce or eliminate various errors in ordinary navigation and positioning systems, such as satellite clock error, ephemeris error, ionospheric error, etc., the above errors are corrected by building the BeiDou ground augmentation system, so that the final positioning result can reach the centimeter level in real time.

[0003] my country has built more than 3,300 BeiDou Ground-Based Augmentation Stations. Faced with increasing business demands, the site selection environment for BeiDou Ground-Based Augmentation Stations has become increasingly difficult. In the existing BeiDou Ground-Based Augmentation System base stations, side wall markers or vertical markers are usually used to build observation piers. They are applicable to a single environment and need to be fixed on horizontal or vertical walls. They cannot be well installed on inclined walls or roofs. Specifically:

[0004] Existing solution 1: side wall label.

[0005] like Figure 1 As shown, the side wall marker is mainly installed on the side of the parapet or vertical wall. Its structure includes a centralizer, an upper flange, a lower flange, a main support rod, an upper support member, a lower support member, and a U-bolt. The upper and lower support members are connected to the side of the parapet or vertical wall through expansion bolts, and the main support rod is connected to the upper and lower support members through upper and lower U-bolts respectively. The support rod is provided with a lower flange, which is connected to the upper flange through bolts. At the same time, the bolts between the flanges are used to adjust the horizontal state of the upper flange. A centralizer is installed in the center of the upper flange, and the screw part above the centralizer is used to install the GNSS antenna.

[0006] The second existing option is to set a standard.

[0007] like Figure 2 As shown in the figure, the vertical mark is mainly installed on the horizontal ground or the top of the wall. Its structure includes a centralizer, an upper flange, a lower flange, a main support rod, and a base. The base is connected to the main support rod by screws, and the support rod is provided with a lower flange, which is connected to the upper flange by bolts. At the same time, the bolts between the flanges are used to adjust the horizontal state of the upper flange. A centralizer is installed in the center of the upper flange, and the screw part above the centralizer is used to install the GNSS antenna.

[0008] As mentioned above, the traditional base station observation pier used in the existing Beidou Ground-Based Augmentation System base station only supports installation on vertical walls or horizontal ground. It does not support the tilt of the installation surface very well. Even if the slight tilt can be leveled through its horizontal adjustment device, the center of gravity of the GNSS antenna will not be able to pass through the base of the observation pier, resulting in insufficient stability for long-term observation, and it cannot be installed at all on large-angle slopes.

[0009] Therefore, a safe, reliable, convenient GNSS observation pier that can be applied to a variety of slopes and gradients is needed. Utility Model Content

[0010] The purpose of the utility model is to provide a multi-scenario rotatable GNSS observation pier, which can be suitable for installation environments of various slopes and gradients, has a safe and reliable overall structure, and is easy to install.

[0013] The bottom end of the support rod is connected to the rotating member 15, the rotating member upper hole 6 and the rotating member lower hole 7 are arranged on the rotating member 15 at intervals, the rotating member lower hole 7 is connected to the rotating seat 9 through the rotating fixing bolt 11, the rotating seat 9 is provided with the rotating slot 8, and the rotating limit bolt 10 passes through the rotating slot 8 and is installed in the rotating member upper hole 6;

[0014] The rotating member 15 drives the support rod to rotate through the rotating slide groove 8, so as to adjust the rotation angle of the support rod. After the angle adjustment is completed, the support rod is tightened and fixed by the rotating limit bolt 10.

[0015] In another preferred embodiment, the rotating seat 9 is fixed to a wall with an inclination angle of 0°-90° by expansion screws.

[0016] In another preferred embodiment, the support rod comprises: an outer support rod 3 and an inner support rod 5;

[0017] The inner support rod 5 is telescopically embedded in the outer support rod 3, the top end of the outer support rod 3 is provided with the lower flange, and the bottom end of the inner support rod 5 is connected to the rotating member 15;

[0018] The installation height of the GNSS antenna is adjusted by adjusting the length of the inner support rod 5 extending beyond the outer support rod 3 , and after the height adjustment is completed, the inner support rod 5 and the outer support rod 3 are tightened and fixed by the height limiting bolts 4 .

[0019] In another preferred example, the installation height of the GNSS antenna can be adjusted between 1000-1600 mm.

[0020] In another preferred embodiment, the outer support rod 3 is tubular, with a wall thickness of 3-4 mm and a diameter of 50-80 mm; the inner support rod 5 is tubular, with a wall thickness of 3-4 mm and a diameter of 40-50 mm.

[0021] In another preferred embodiment, it further includes: a base 14;

[0022] The rotating seat 9 is connected to the base 14;

[0023] The base 14 is fixed to a wall with an inclination angle of 0°-90° by expansion screws.

[0024] In another preferred example, a slide rail 13 is provided on the base 14 , and the rotating seat 9 is slidably connected to the slide rail 13 by rotating the sliding bolt 12 .

[0025] In another preferred embodiment, the sliding distance of the rotating seat 9 can be adjusted between 0-800 mm through the sliding rail 13 .

[0026] In another preferred embodiment, the rotating member 15, the rotating seat 9 and the base 14 are all made of a stainless steel plate with a thickness of 4-5 mm.

[0027] In another preferred example, the leveling bolt 1, the rotation limiting bolt 10, the rotation fixing bolt 11, the height limiting bolt 4 and the rotation sliding bolt 12 all include corresponding bolts and nuts.

[0028] In another preferred embodiment, the rotation angle of the support rod can be adjusted between 0°-90°.

[0029] Compared with the prior art, the main differences and effects of the implementation of the utility model are:

[0030] By setting the rotating parts, rotating seats and rotating slides, the rotation angle of the support rod can be freely adjusted, which increases the freedom of installation of the observation pier. It can be suitable for installation environments with various slopes and slopes. The overall structure is safe and reliable and easy to install.

[0031] Furthermore, the multi-scenario rotatable GNSS observation pier can well meet the installation support for large-angle inclined walls. Theoretically, it can support inclined walls of 0°-90°. According to the actual situation on site, the direction and height of the observation pier can also be adjusted. At the same time, after installation, the center of gravity of the GNSS antenna still passes through the antenna base, which can better meet the stability requirements.

Technically, only one can be used, and it is impossible to use them at the same time. Feature E can be combined with feature C technically. Then, the solution of A+B+C+D should not be deemed to have been recorded because it is technically infeasible, and the solution of A+B+C+E should be deemed to have been recorded.
