Description

Technical Field

[0001] This utility model relates to the field of RTK measuring instrument technology, specifically a high-stability RTK measuring instrument suitable for gardens. Background Technology

[0002] In existing technologies, using RTK technology combined with a network CORS account for high-precision positioning has become one of the main methods for landscape surveying.

[0003] In landscape surveying, RTK main units typically require support from a centering rod and are positioned by hand by the operator. However, hand-held centering rods are susceptible to factors such as human body vibration, wind, and uneven ground during actual operation, causing the RTK main unit's posture and spatial position to constantly change. This results in drifting of the positioning point, affecting the stability and repeatability of RTK measurements.

[0004] In addition, some garden measuring points are located at the base of tree trunks, inside tree pits, or near shrubs. In such environments, it is difficult for surveyors to stably fix and place the centering rod at the precise measuring point. Moreover, handheld measurement requires manual maintenance of the centering rod's verticality, which is both laborious and difficult to maintain stability for a long time. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figures 1-4 This utility model discloses a highly stable RTK measuring instrument suitable for gardens, including an existing centering rod 1 and a main unit 2 installed on top of the centering rod 1. In this embodiment, the centering rod 1 can be cleverly fixed to the tree trunk, thereby effectively avoiding the shaking or offset of the RTK measuring instrument caused by manual handling or uneven ground, effectively improving the stability and repeatability of the measurement, and solving the problems of difficult and unstable positioning when measuring next to trees.

[0033] Specifically, such as Figure 1 As shown, the fixed base is a fixing plate 3. The fixing plate 3 is arc-shaped and can fit the tree trunk. The inner arc surface facing the tree trunk is provided with an anti-slip pad layer. The anti-slip pad layer is preferably made of a flexible material, such as rubber, and can be provided with raised dots or stripes to enhance the friction with the bark surface and avoid scratching damage to the bark.

[0034] The fixing plate 3 is fixed to the side of the tree trunk by a fixing mechanism, which specifically includes a strap 4 and a U-shaped plate 5, such as... Figure 2 As shown, a strap 4 is fixedly connected to one side of the fixing plate 3, and a U-shaped plate 5 is fixedly connected to the other side. A limiting space is formed between the U-shaped plate 5 and the fixing plate 3. After the strap 4 passes around the tree trunk, it passes through the limiting space and is then pasted and fixed to itself in the opposite direction, thereby binding and fixing the fixing plate 3 to the tree trunk. The overall structure is simple, easy to install, and suitable for trees of different diameters.

[0035] In this embodiment, at least two sets of fixing mechanisms are preferably provided on the fixing plate 3 to ensure the stability of the fixing plate 3 and prevent displacement or detachment. After fixing, the overall posture can be referenced. Figure 4 .

[0036] like Figure 3 As shown, a base plate 6 is fixedly installed perpendicular to the fixed plate 3. A rotating ball 7 is rotatably installed in the ball groove formed inside the base plate 6. A bearing sleeve 8 for supporting the centering rod 1 is fixedly installed on the top of the rotating ball 7. In this embodiment, the rotating ball 7 can be positioned by damping in the ball groove to ensure that the position of the rotating ball 7 is stable after rotation adjustment.

[0037] By rotating the ball 7 within the ball groove, the bearing sleeve 8, which supports the centering rod 1, can be adjusted in multiple directions, thereby ensuring the verticality of the centering rod 1.

[0038] In actual use, first fix the fixing plate 3, and then insert the bottom end of the centering rod 1 into the bearing sleeve 8. The size of the bearing sleeve 8 is preferably corresponding to the size of the centering rod 1.

[0039] Furthermore, a circumferential limiting flange can be provided on the inner wall of the bearing sleeve 8 to further limit the centering rod 1 and ensure the stability of the centering rod 1 during installation.

[0040] To facilitate the adjustment of the bearing sleeve 8, such as Figure 3 As shown, an upper movable opening 9 is provided at the top of the ball groove to allow the bearing sleeve 8 to swing in multiple directions;

[0041] In addition, a lower movable opening 10 is provided at the bottom of the ball groove. The lower movable opening 10 is used to allow the laser lamp 11 to move. The laser lamp 11 is fixedly installed at the bottom of the rotating ball 7.

[0042] The laser beam emitted by the laser lamp 11 can be projected onto the ground through the lower movable port 10, so that the spatial position of the centering rod 1 can be accurately projected onto the actual measuring point position on the ground, thereby enabling the surveyor to quickly and accurately locate the actual measuring point position on the ground, improving centering efficiency and point accuracy.

[0043] Example 2:

[0044] Please see Figure 3 Based on Embodiment 1, in order to further ensure the stability of the position of the rotating ball 7, in this embodiment, a side groove 12 is also provided on the inner wall of the ball groove. A pressure plate 13 is slidably provided in the side groove 12. The pressure plate 13 is used to press on the rotating ball 7 to restrict its rotation, thereby ensuring the stability of its position and maintaining a fixed posture after adjustment, thus ensuring that the centering rod 1 remains vertical and stable during the measurement process.

[0045] In this embodiment, the pressure plate 13 has a concave surface on the side facing the rotating ball 7. This concave surface cooperates with the ball wall and can provide a large friction force when pressed.

[0046] like Figure 3 The side groove 12 has a threaded hole at the end away from the rotating ball 7. A threaded rod 14 is screwed into the threaded hole. One end of the threaded rod 14 is rotatably connected to the pressure plate 13, and the other end is fixedly connected to the clamping handle 15. In use, the threaded rod 14 is turned by the clamping handle 15, so that the threaded rod 14 moves under the action of the thread, which can drive the pressure plate 13 to move, so that the pressure plate 13 is pressed against the rotating ball 7 to lock its position, or away from the rotating ball 7 so that it can rotate freely.

[0047] The design of the pressure plate 13 enables efficient adjustment and locking of the rotating ball 7, making the entire leveling mechanism more reliable and effectively preventing attitude changes caused by external vibration, wind or collision, thereby further improving the stability of the RTK measuring instrument.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
