Description

Technical Field

[0001] This utility model relates to the field of GNSS base station installation technology, and in particular to a mounting bracket for a GNSS base station used in forestry surveying. Background Technology

[0002] Forestry surveying refers to the measurement work that provides maps or data for forest surveys, management status assessments, and other purposes. It is an important application of surveying in the forestry field. High-precision positioning data provided by GNSS (Global Navigation Satellite System) is used to create accurate forest distribution maps, assess forest resources, and monitor forest changes. GNSS base stations are the key equipment for achieving this high-precision positioning. They receive signals transmitted by satellites and use precise measurement techniques to determine the satellite system's position and time data, providing high-precision position and time information for forestry surveying.

[0003] In forestry surveying, a suitable installation location needs to be selected for GNSS base stations. This location should be far away from sources of electromagnetic interference, such as high-voltage lines and substations, and ensure that the measurement point is in an open area with no large obstructions above the ±15° height cutoff angle to facilitate satellite signal reception. Then, according to design requirements, the GNSS base station is installed in a geologically sound, stable location that is easy to preserve long-term. Typically, the observation site should be flat, wide, unobstructed, and at a high elevation with good visibility. The main function of the GNSS base station mounting bracket is to provide a stable support platform, ensuring the GNSS base station can be stably installed in the designated location and avoiding positioning errors caused by unstable foundations or external interference. Simultaneously, the bracket design also considers ease of maintenance and adjustment, allowing personnel to easily inspect and calibrate the GNSS base station.

[0004] However, existing forestry surveying GNSS base station mounting brackets are large in size and heavy, making them inconvenient to move and operate manually. Utility Model Content

[0005] In view of this, the present invention proposes a mounting bracket for a GNSS base station in forestry surveying, in order to solve the problems mentioned above.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A mounting bracket for a GNSS base station used in forestry surveying includes a housing, a winding mechanism, and a controller. The housing has a sliding groove and a recess on its side. A lead screw is rotatably mounted within the sliding groove. One end of the lead screw is rotatably connected to the housing, and the other end passes through the housing and is connected to a first motor. The two ends of the lead screw have opposite rotational directions and are equipped with opposing moving blocks. Two recesses are located opposite each other on one side of the sliding groove. A winding mechanism is mounted within the recess, comprising a drum, a first rotating shaft, a worm gear, a worm, and a second motor. The housing has a receiving cavity located on one side of the recess. The first rotating shaft is rotatably mounted within the recess, with one end rotatably connected to the housing and the other end passing through the housing. The first motor enters the receiving cavity and is connected to a worm gear. The second motor is located in the receiving cavity, and its output shaft is equipped with a worm. The worm meshes with the worm gear. A belt is provided on the drum, and the other end of the belt is connected to a moving block. An antenna is provided on the side of the housing. Button 1 and Button 2 are provided on the side of the housing near the belt. Button 1 and Button 2 are used to control the forward and reverse rotation of the first motor. Button 3 and Button 4 are provided on the other side of the housing near the belt. Button 3 and Button 4 are used to control the forward and reverse rotation of the second motor. The controller is located in the receiving cavity and is electrically connected to the antenna, the first motor, the second motor, and Buttons 1, 2, 3, and 4.

[0008] Preferably, the antenna includes a support plate, a second rotating shaft, a third rotating shaft, a rotating rod, a connecting rod, a feed tube, and an antenna panel. The two support plates are disposed opposite to each other on the side of the housing. The second rotating shaft and the third rotating shaft are rotatably disposed between the two support plates. A rotating rod is rotatably disposed on the second rotating shaft. A connecting rod is connected to the ends of the two rotating rods. A feed tube is rotatably sleeved in the middle of the connecting rod. An antenna panel is disposed on the second rotating shaft.

[0009] Preferably, it also includes a support leg, which includes a foot and a screw. The side of the housing is provided with a threaded hole, and the screw is disposed in the threaded hole, with its bottom connected to the top of the foot.

[0010] Preferably, it also includes a level, which is located on the side of the box.

[0011] Preferably, it also includes an electric actuator, and the bottom of the housing is provided with a countersunk hole, and the electric actuator is provided in the countersunk hole.

[0012] Preferably, it also includes a support plate, which is disposed at the bottom of the electric actuator.

[0013] Preferably, the top surface of the support plate abuts against the top surface of the countersunk hole, and its bottom surface is flush with the bottom surface of the box body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A first motor is installed. The rotation of the first motor drives the lead screw to rotate, which in turn drives two moving blocks to separate or move closer together. The operator can control the forward and reverse rotation of the first motor by operating buttons one and two, thereby increasing or decreasing the belt spacing. This can be adjusted according to different body types and usage habits, allowing the operator to carry the support more comfortably. The other end of the belt is connected to the retractor. Buttons three and four can be manually operated to control the forward and reverse rotation of the second motor, allowing the belt to be tightened or released. This ensures that the belt can be manually adjusted to a suitable tightness when worn, preventing the support from shaking or falling off during movement, thus improving the stability and safety of the support movement.

[0016] 2. Install electric actuators. The telescopic end of the electric actuators can extend to provide vertical support for the support frame, allowing the person carrying the load to rest and recover their strength. The telescopic end of the electric actuators can also extend to raise the support frame, making it easier to place the support frame on the back.

[0017] 3. Set up a level and adjustable support legs. By rotating the screw, the distance between the feet and the threaded hole can be adjusted. Place the bracket on the ground with its side facing down. While observing the level, adjust the distance between the feet and the threaded hole to adjust the bracket to a horizontal position, which is helpful for positioning the bracket.

[0026] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0027] See Figures 1 to 6 This utility model provides a GNSS base station mounting bracket for forestry surveying, including a housing 1, a winding mechanism, and a controller 20. The housing 1 has a sliding groove 2 and a recess 3 on its side. A lead screw 4 is rotatably mounted in the sliding groove 2. One end of the lead screw 4 is rotatably connected to the housing 1, and the other end passes through the housing 1 and is connected to a first motor 6. The first motor 6 is a stepper motor. The two ends of the lead screw 4 have opposite rotation directions and are equipped with opposing moving blocks 5. Two recesses 3 are located opposite each other on one side of the sliding groove 2. A winding mechanism is installed in the recess 3. The winding mechanism includes a drum 8, a first rotating shaft 13, a worm gear 28, a worm 29, and a second motor 30. The housing 1 has a receiving cavity 27 located on one side of the recess 3. The first rotating shaft 13 is rotatably mounted in the recess 3, with one end rotatably connected to the housing 1 and the other end passing through the housing 1 into the receiving cavity 27 and connected to the worm gear 28. The second motor 30 is located within the receiving cavity 27. The second motor 30 is a stepper motor, and its output shaft is equipped with a worm gear 29, which meshes with a worm wheel 28. A belt 7 is provided on the drum 8, and the other end of the belt 7 is connected to the moving block 5. An antenna is provided on the side of the housing 1. A button 15 and a button 26 are provided on the side of the housing 1 near the belt 7. The button 15 and the button 26 are used to control the forward and reverse rotation of the first motor 6. A button 31 and a button 42 are provided on the other side of the housing 1 near the belt 7. The button 31 and the button 42 are used to control the forward and reverse rotation of the second motor 30. The controller 20 is located within the receiving cavity 27 and is electrically connected to the antenna, the first motor 6, the second motor 30, and the buttons 15, 16, 31, and 32. The controller 20 uses a low-power microprocessor of model STM32-L0.

[0028] When the GNSS base station mounting bracket needs to be moved, the first motor 6 is controlled to rotate forward and reverse by operating buttons 15 and 16. The rotation of the first motor 6 drives the lead screw 4 to rotate. The lead screw 4 and the moving block 5 are threadedly connected. The moving block 5 moves along the axis of the lead screw 4. The threads at both ends of the lead screw 4 are opposite. Depending on the installation direction of the first motor 6, the moving blocks 5 move closer or further apart, thereby adjusting the spacing of the belt 7. After adjusting to a suitable spacing, the operator places the belt 7 on their shoulders and then controls the second motor 30 to rotate forward and reverse by operating buttons 31 and 32. The rotation of the second motor 30 drives the worm gear 29 to rotate. The rotation of the worm gear 29 drives the worm wheel 28 to rotate. The rotation of the worm wheel 28 drives the first rotating shaft 13 to rotate, thereby driving the drum 8 to rotate, realizing the tightening and loosening of the belt 7. Adjusting the belt 7 to a suitable tension ensures that the bracket will not shake or fall off during the movement, improving the stability and safety of the bracket movement. Once the GNSS base station mounting bracket reaches the surveying position, the winding mechanism is activated to tighten the belt 7. The belt 7 is located in the groove 3. Then, the belt 7 is placed on the ground with one side facing down, and its antenna is unfolded to receive satellite signals and perform surveying operations.

[0029] Preferably, the antenna includes a support plate 12, a second rotating shaft 21, a third rotating shaft 26, a rotating rod 17, a connecting rod 18, a feed tube 19, and an antenna panel 14. The two support plates 12 are disposed opposite to each other on the side of the housing 1. The second rotating shaft 21 and the third rotating shaft 26 are rotatably disposed between the two support plates 12. The second rotating shaft 21 and the third rotating shaft 26 have friction when rotating, which plays a certain damping role during the rotation process. The rotating shaft can be held in the desired position when it is rotated. The rotating rod 17 is rotatably disposed on the second rotating shaft 21. The ends of the two rotating rods 17 are connected to the connecting rod 18. The feed tube 19 is rotatably sleeved in the middle of the connecting rod 18. The antenna panel 14 is disposed on the second rotating shaft 21.

[0030] During forestry surveying, the GNSS base station mounting bracket is first placed side down on the ground at a predetermined location. The antenna panel 14 is rotated around the second pivot 21 by a certain angle. Then, the rotating rod 17 is rotated around the first pivot 13 by a certain angle, and the feed tube 19 is rotated so that the feed tube 19 is directly opposite the antenna panel 14. The antenna panel 14 is then operated to start searching for satellite signals to complete the surveying operation. After the surveying operation is completed, the antenna panel 14 and the rotating rod 17 can be reset. This reduces the size of the GNSS base station mounting bracket, which is beneficial for improving mobility.

[0031] Preferably, it also includes a support leg, which includes a foot 22 and a screw 23. The side of the housing 1 is provided with a threaded hole 24, and the screw 23 is disposed in the threaded hole 24, with its bottom connected to the top of the foot 22.

[0032] When the GNSS base station mounting bracket is placed side down, the support legs support the GNSS base station mounting bracket. The height of the bracket can be adjusted by rotating the foot 22 to drive the screw 23 to rotate, which is beneficial for the installation of the bracket and improves convenience.

[0033] Preferably, it also includes a level 9, which is located on the side of the housing 1.

[0034] When the GNSS base station mounting bracket is placed side down, the level 9 is used to detect the level of the bracket. By rotating the screw 23, the distance between the foot 22 and the threaded hole 24 can be adjusted. By placing the bracket side down on the ground and observing the level 9, the distance between the foot 22 and the threaded hole 24 can be adjusted to make the bracket level, which is helpful for positioning the bracket.

[0035] Preferably, it also includes an electric actuator 10, and the bottom of the housing 1 is provided with a countersunk hole 25, and the electric actuator 10 is provided in the countersunk hole 25.

[0036] When operators need to take a short break while carrying the GNSS base station installation bracket, they can activate the electric push rod 10. The telescopic end of the electric push rod 10 extends and touches the ground, providing vertical support for the bracket, allowing the personnel carrying it to rest and recover their strength. When it is necessary to lower or carry the bracket, the telescopic end of the electric push rod 10 can extend to raise the bracket to a certain height, which is beneficial for the operation of the bracket.

[0037] Preferably, it also includes a support plate 11, which is disposed at the bottom of the electric actuator 10.

[0038] The support plate 11 can increase the contact area with the ground, which can distribute the load over a larger area, allowing the GNSS base station mounting bracket to be placed in different soil environments.

[0039] Preferably, the top surface of the support plate 11 abuts against the top surface of the countersunk hole 25, and its bottom surface is flush with the bottom surface of the box body 1.

[0040] When the operator carries the GNSS base station mounting bracket and moves it, the electric push rod 10 will be activated. The telescopic end of the electric push rod 10 will shorten and drive the support plate 11 to move, so that the top surface of the support plate 11 abuts against the top surface of the countersunk hole 25. This can reduce the overall size of the GNSS base station mounting bracket and improve its mobility.

[0041] 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.
