Description

Technical Field

[0001] This utility model relates to the field of GNSS tripod technology, and more specifically, to a suspended counterweight stabilization device for GNSS tripods used in windproof environments. Background Technology

[0002] In GNSS surveying operations, the tripod, as the core support structure for carrying the surveying equipment, directly determines the accuracy and reliability of the measurement data. However, actual surveying scenarios often face complex environmental interference, especially when operating in open fields, high-altitude platforms, or windy areas. Wind forces can easily cause the tripod to sway horizontally and twist. If the tripod is placed on uneven ground, it will further exacerbate the problem of support imbalance, seriously affecting the attitude stability of the surveying equipment, increasing measurement errors, and making it difficult to meet the requirements of high-precision measurement.

[0003] Currently, to improve the stability of tripods, counterweights are typically added to the three legs of the tripod or additional support is provided by rigid connections. However, sandbags or counterweights placed next to the tripod legs have limited stabilizing torque and cannot effectively suppress torsional vibrations of the tripod. On uneven ground, traditional rigid counterweights cannot guarantee that the counterweight force is always perpendicular to the central axis of the tripod and may instead introduce additional torque, exacerbating tripod instability. Therefore, this invention proposes a suspended counterweight stabilization device for GNSS tripods in windproof environments. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a suspended counterweight stabilization device for GNSS tripods in windy environments, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suspended counterweight stabilizing device for GNSS tripods in windproof environments, comprising a connecting plate, wherein the connecting plate is provided with a hook adapted to the hanging ring structure on the GNSS tripod, and the bottom of the connecting plate is connected to a screw via a universal structure, wherein a counterweight structure is installed on the screw.

[0006] Preferably, the universal structure includes a first universal seat, a second universal seat, and a universal ball, wherein the first universal seat is fixedly installed at the bottom of the connecting plate, the second universal seat is fixedly installed at the top of the screw, and the universal ball is movably installed between the first universal seat and the second universal seat.

[0007] In order to allow the screw to swing slightly under wind force, the structure always maintains the counterweight vertically downward to generate a restoring torque, thereby suppressing the horizontal and torsional swaying of the tripod.

[0008] Preferably, the counterweight structure includes a metal tray mounted on the outside of the screw. A through hole is formed at the center of the surface of the metal tray, and a sliding sleeve is fixedly installed inside the through hole. The metal tray is slidably connected to the outside of the screw via the sliding sleeve. A limit nut is provided at the bottom of the metal tray, and the limit nut is threaded to the outside of the screw to limit and support the bottom of the metal tray. Several counterweight blocks are arranged outside the screw and above the metal tray. The counterweight blocks have a disc structure and a clearance opening on their surface. The counterweight blocks are mounted on the screw through the clearance opening. A soft magnet is attached to the bottom of the counterweight block, and the soft magnet is adapted to the structure of the counterweight block.

[0009] This structure allows for adjustment of the metal tray height to accommodate the counterweight installation, while using limit nuts to secure the tray and soft magnets to prevent the counterweight from detaching, thereby achieving precise weight distribution and improving the overall stability of the device.

[0010] The technical effects and advantages of this utility model are as follows: 1. By setting up a universal structure, which consists of a first universal seat, a second universal seat, and a universal ball, the screw can swing slightly with the wind and always keep the counterweight vertically downward. Based on the pendulum principle, a restoring torque is generated, which can effectively suppress the horizontal swaying and torsion of the GNSS tripod caused by wind interference or uneven ground, greatly improve the stability of the tripod in complex windproof environments, and provide a reliable guarantee for measurement accuracy. 2. By setting up a counterweight structure, which includes a sliding adjustable metal tray, a limit nut, and a counterweight block with a soft magnet, the height of the metal tray can be adjusted according to the actual wind protection requirements and secured by the limit nut. This allows for the installation of different numbers of counterweight blocks to achieve precise weight distribution, increasing the overall weight of the tripod and improving wind resistance. At the same time, the magnetic attraction of the soft magnets prevents the counterweight blocks from detaching from the screw after stacking. This ensures the safety of the counterweight while further enhancing the adaptability and stability of the device for different usage scenarios. Attached Figure Description

[0013] 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.

[0014] As attached Figure 1-5 The suspended counterweight stabilization device for GNSS tripods in windproof environments shown includes a connecting plate 1, on which a hook 2 adapted to the hanging ring structure on the GNSS tripod is provided, and a screw 3 is connected to the bottom of the connecting plate 1 through a universal structure, on which a counterweight structure is installed.

[0015] Specifically, in this structure, the hook 2 on the connecting plate 1 can be suspended at the hanging ring on the GNSS tripod. When performing this operation, it is further limited that the GNSS tripod must be equipped with extra hanging rings, or hanging rings must be pre-installed at the position on the GNSS tripod where counterweight is required. The shape of the hook 2 can be selected according to the actual situation.

[0016] After the hook 2 is suspended on the hanging ring, the screw 3, through the universal structure, is allowed to swing slightly at the bottom of the connecting plate 1 under the action of wind force, always keeping the direction of the counterweight force vertically downward. The restoring torque is generated by using the pendulum principle, which can greatly suppress the horizontal and torsional sway of the tripod, thereby better adapting to uneven ground and effectively suppressing the sway of the tripod, improving measurement accuracy. A counterweight structure is installed on screw 3, which can apply the gravity of the GNSS tripod to improve stability.

[0017] The structure described above in this embodiment will be further explained below with reference to the accompanying drawings: In this embodiment, as shown in the appendix Figure 1 , 2 As shown, the universal structure includes a first universal seat 4, a second universal seat 5, and a universal ball 6. The first universal seat 4 is fixedly installed at the bottom of the connecting plate 1, the second universal seat 5 is fixedly installed at the top of the screw 3, and the universal ball 6 is movably installed between the first universal seat 4 and the second universal seat 5.

[0018] Specifically, in this structure, the second universal joint 5 can move within a range between the universal ball 6 and the first mounting base, thereby ensuring that the screw 3 can swing slightly.

[0019] In this embodiment, as shown in the appendix Figure 1 , 3 As shown in Figures 4 and 5, the counterweight structure includes a metal tray 7, which is installed on the outside of the screw 3. A through hole is opened in the center of the surface of the metal tray 7, and a sliding sleeve 8 is fixedly installed inside the through hole. The metal tray 7 is slidably connected to the outside of the screw 3 through the sliding sleeve 8. A limit nut 9 is provided at the bottom of the metal tray 7, which is threaded to the outside of the screw 3 to limit and support the bottom of the metal tray 7. Several counterweight blocks 10 are provided on the outside of the screw 3 and above the metal tray 7. The counterweight blocks 10 are disc structures, and a clearance opening 11 is opened on the surface of the counterweight blocks 10. The counterweight blocks 10 are installed on the screw 3 through the clearance opening 11. A soft magnet 12 is attached to the bottom of the counterweight blocks 10, and the soft magnet 12 is adapted to the structure of the counterweight blocks 10.

[0020] Specifically, in this structure, the metal tray 7 can slide outside the screw 3 via the sliding sleeve 8 to adjust the height of the support tray. Different numbers of counterweights 10 can be installed according to the actual situation. After the support tray is slidably adjusted, the bottom of the adjusted metal tray 7 can be limited and supported by the limit nut 9 rotating on the screw 3 through the thread and being restricted by the thread, thus preventing the metal tray 7 from sliding without reason. After the height of the metal tray 7 is adjusted, the corresponding number of counterweights 10 are selected according to the actual counterweight weight, and the counterweights 10 are installed on the outside of the screw 3 through the clearance opening 11. The bottom counterweight 10 is supported by the metal tray 7, while the upper counterweights 10 are stacked layer by layer to achieve the purpose of counterweight. A soft magnet 12 is installed at the bottom of the counterweight 10, so that the counterweights 10 and the metal tray 7 are magnetically attracted to each other, preventing the counterweights 10 from detaching from the screw 3. The magnetic force of the soft magnet 12 can be selected according to the actual situation.

[0021] Working principle of this utility model: This application provides a suspended counterweight stabilization device for GNSS tripods in windproof environments. In specific use, it is necessary to first ensure that the GNSS tripod is equipped with extra hanging rings or to install hanging rings in advance at the position where counterweight is required. Then, accurately align the hook 2 on the connecting plate 1 with the tripod hanging ring and suspend it to complete the initial installation of the device and the tripod, laying the foundation for the subsequent counterweight stabilization function. After the hanging ring is suspended, according to the actual wind protection requirements and the stability and accuracy requirements of the tripod, the support height of the metal tray 7 is adjusted by sliding the sliding sleeve 8 on the metal tray 7 outside the screw 3. After the height is determined, the limiting nut 9 outside the screw 3 is rotated. The limiting effect of the threaded connection is used to provide stable support from the bottom of the metal tray 7 to prevent the tray from sliding without reason in subsequent use and to ensure the stability of the counterweight support foundation. According to the required counterweight weight, select the appropriate number of disc-shaped counterweight blocks 10, and install the counterweight blocks 10 sequentially on the outside of the screw 3 through the clearance openings 11 on their surface. The bottom counterweight block 10 is supported by the adjusted metal tray 7. The upper counterweight blocks 10 are stacked layer by layer to achieve the target counterweight weight, increase the overall gravity of the tripod, and improve wind resistance. At the same time, because each counterweight block 10 has a soft magnet 12 that is compatible with its own structure attached to its bottom, during the stacking process, the counterweight blocks 10 will have a magnetic attraction between each other and between the bottom counterweight block 10 and the metal tray 7, which prevents the counterweight blocks 10 from falling off the screw 3, and further ensures the safety and stability of the counterweight structure. The bottom of the connecting plate 1 is connected to the screw 3 through a universal structure consisting of the first universal seat 4, the universal ball 6 and the second universal seat 5. When encountering wind, the universal ball 6 can move slightly between the first universal seat 4 and the second universal seat 5, causing the screw 3 and the counterweight structure to swing synchronously, always keeping the counterweight force vertically downward. Based on the pendulum principle, the vertical counterweight force can generate a restoring torque, effectively suppressing the horizontal swaying and torsion of the tripod caused by wind or uneven ground, and balancing the influence of external interference on the stability of the tripod in real time.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
