Description

Technical Field

[0001] This invention relates to the field of GPS receiving device technology, and more specifically to a GPS-based land planning and surveying device. Background Technology

[0002] GPS positioning devices are mainly used for measuring time and speed, as well as geodetic surveying, such as underwater topographic surveying, crustal deformation measurement, deformation monitoring of dams and large buildings, and floating car data. When GPS positioning devices are installed on mobile surveying vehicles for data monitoring, they often need to be fixedly installed to prevent them from falling off during movement.

[0003] In the prior art, such as the GPS receiver bracket disclosed in CN221281230U, a rectangular base plate is provided with buffer protection components at the four corners of the top of the rectangular base plate. The buffer protection components include inclined support braces at the four corners of the rectangular base plate. A cross groove is opened at the center of the support brace, and an elastic support rod is slidably inserted into the inner wall of the cross groove. The top of the elastic support rod is connected to a fixed top plate, and an installation groove is opened at the center of the top of the fixed top plate. Fixed blocks are provided on the fixed top plate on both sides of the installation groove, and fastening pressure plates are installed on the fixed blocks by bolts. This utility model provides inclined sliding elastic support rods at the four corners of the bottom of the fixed top plate for sliding buffering treatment, and works in conjunction with a hydraulic damping shock absorber set in the middle of the fixed top plate to buffer the vibration in time, thereby reducing the damage of external shaking to the internal components of the GPS, thus extending the service life and improving the mapping accuracy.

[0004] When fixing the GPS receiver, it is secured with a bracket, but it is difficult to adjust the measuring angle of the measuring device. Since the device is used for land planning, it needs to be used in the field. During use, due to the influence of terrain, the device is difficult to fix and is prone to tipping over. For example, when measuring on sloping terrain, after the measuring personnel have finished adjusting, they need to keep a certain distance from the device to reduce the influence of their human body on the GPS signal. When the device tipps over, it is difficult to protect it in time, which can easily cause the optical components of the measuring device to be scratched, resulting in significant damage.

[0005] Therefore, this invention proposes a GPS-based land surveying and planning device. Summary of the Invention

[0006] The purpose of this invention is to provide a GPS-based land surveying and planning device to address the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0008] A GPS-based land surveying and planning device includes a surveying device with a GPS receiver mounted thereon, and further includes:

[0009] Mounting plate, on which an adjustment device is mounted, the adjustment device including a flat rotating plate rotatably mounted on the mounting plate, a vertical rotating platform hinged to the flat rotating plate, and a measuring device mounted on the vertical rotating platform;

[0010] A bracket structure is mounted on a mounting plate. The bracket structure includes a bracket rod hinged to the mounting plate, with a pin installed at the free end of the bracket rod. A protective plate for shielding or unshielding optical elements is installed on the measuring device. A triggering structure is installed on the bracket rod. The triggering structure is used to drive the protective plate to shield or unshield the optical elements. When the pin is in an unloaded state, the triggering structure forces the protective plate to shield the optical elements.

[0011] Furthermore, the triggering structure includes a mounting cavity formed on the mounting plate, a ring plate slidably mounted in the mounting cavity, a connecting spring installed between the ring plate and the mounting cavity, a connecting plate hinged to the free end of the support rod, a contact plate slidably mounted on the connecting plate, an abutting spring installed between the contact plate and the connecting plate, a pin mounted on the contact plate, a pull rope mounted on the contact plate, an abutting rod slidably mounted on the hinged end of the support rod for abutting the ring plate, the pull rope connected to the abutting rod, a torsion spring installed between the abutting rod and the support rod, a receiving shell mounted on the measuring device, a pushing spring connected to the protective plate installed inside the receiving shell, a trigger plate slidably mounted on the receiving shell for blocking the protective plate, a force-bearing inclined surface formed on the trigger plate, a pushing rod mounted on the ring plate for abutting the trigger plate, and when the pushing rod abuts the trigger plate, it forces the trigger plate to release its blockage of the protective plate.

[0012] Furthermore, a first lever, a second lever, and a third lever are rotatably mounted within the mounting cavity. Each of the first, second, and third levers has a force-applying end and a force-receiving end. The force-receiving end of the first lever contacts the actuating rod, and the force-applying end contacts the force-receiving end of the second lever. The force-receiving end of the first lever is shorter than the force-applying end. The force-applying end of the second lever contacts the force-receiving end of the third lever. A hinge block is hinged to the force-applying end of the third lever. The force-receiving end of the third lever is shorter than the force-applying end. An annular plate is slidably mounted on the mounting plate. The annular plate is slidably connected to the hinge block. A force-applying inclined surface parallel to the force-receiving inclined surface on the trigger plate is provided on the annular plate.

[0013] Furthermore, an extension rod is installed on the rotating shaft of the flat rotating plate, and a wedge block is installed on the extension rod. Multiple wedge grooves for accommodating the wedge blocks are opened on the ring plate. The wedge grooves are arranged in a ring array along the center of the ring plate. When the abutting rod abuts against the ring plate, the wedge grooves are used to accommodate the wedge blocks.

[0014] Furthermore, a sliding rod is mounted on the mounting plate, a collar is slidably mounted on the sliding rod, and a hinge rod is hinged to the collar, with the free end of the hinge rod hinged to the support rod.

[0015] Furthermore, the sliding rod has a cavity communicating with the mounting cavity, a counterweight is installed on the ring plate, a sliding block is installed on the collar, and a through groove for accommodating the sliding block is provided on the sliding rod. The counterweight is used to press the sliding block.

[0016] Furthermore, a handle is installed on the side wall of the protective plate, and a long slot is provided on the housing to accommodate the handle, which forces the interior of the housing to communicate with the outside.

[0017] Furthermore, a worm gear is installed on the vertical turntable shaft, a hollow circular plate is rotatably installed on the mounting plate, and a worm gear that meshes with the worm gear is rotatably installed on the hollow circular plate.

[0018] Furthermore, an insert plate is installed on the vertical rotating platform, and a slot is opened on the insert plate. A disassembly plate for insertion into the slot is installed on the measuring device. A compression spring is installed in the slot, and a limiting plate for blocking the disassembly plate is installed on the free end of the compression spring.

[0019] Furthermore, the insert plate is rotatably mounted on the vertical rotating platform. The insert plate has a groove for accommodating the limiting plate. One side of the groove has an opening that communicates with the outside. An external plate that slides with the opening is mounted on the limiting plate. A support block for abutting against the external plate is mounted on the vertical rotating platform.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention involves mounting a support rod on a mounting plate and inserting it into the ground via a pin. During the process, when the pin is inserted into the ground, the triggering structure will not be triggered. When the pin is not in the ground, it indicates that the device has tipped over. At this time, the triggering structure drives the protective plate to shield the optical elements on the measuring device. Thus, when the device tipps over, the protective plate protects the optical elements, reducing the possibility of damage to the device. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figure 1 - Figure 11As shown, an embodiment of the present invention proposes a GPS-based land surveying device for land planning, including a surveying device 3 equipped with a GPS receiver. The surveying device 3 also includes a host unit, such as a display screen, control panel, and camera, for measuring terrain. This invention is applicable to land planning and is therefore often used in field scenarios. It also includes:

[0036] Mounting plate 1 has an adjustment device 2 mounted on it. The adjustment device 2 includes a flat rotating plate 201 rotatably mounted on the mounting plate 1, and a vertical rotating platform 202 hinged to the flat rotating plate 201. The measuring device 3 is mounted on the vertical rotating platform 202. The flat rotating plate 201 and the mounting plate 1 rotate tightly together. The two can be kept in close rotation by installing a rubber ring. The vertical rotating platform 202 also rotates tightly, and the two can be kept in close rotation by the above structure. When the device is measuring, the horizontal position of the lens of the measuring device 3 is adjusted by rotating the flat rotating plate 201, and the vertical position of the lens of the measuring device 3 is adjusted by rotating the vertical rotating platform 202. This allows the device to measure and plan the terrain in different directions without moving the device, reducing the number of times the device is moved, thereby reducing the possibility of damage to the device during transportation and increasing the practicality of the device.

[0037] The support structure 4 is installed on the mounting plate 1. The support structure 4 includes a support rod 401 hinged to the mounting plate 1. A pin 402 is installed at the free end of the support rod 401. The free end of the pin 402 is a pointed tip. Since the ground in the field is mostly soil, when the device is fixed, it is inserted into the ground through the pointed tip of the pin 402, which increases the stability of the device when measuring, reduces the possibility of the device tipping over, and increases the safety of the device when in use.

[0038] The measuring device 3 is equipped with a protective plate 5 for shielding or removing the shielding of optical elements. Figure 1 From the main perspective, the protective plate 5 is slidably mounted on the measuring device 3 in the vertical direction. When the device is measuring, the protective plate 5 is slid down to release it from obstructing the lens of the measuring device 3. The protective plate 5 has a slot. When the protective plate 5 obstructs the lens of the measuring device 3, the edge of the slot of the protective plate 5 contacts the housing of the measuring device 3. The slot is directly facing the lens, so that even if the device is hit, it will not directly collide with the lens, reducing the possibility of damage to the lens when tilted and increasing the practicality of the device.

[0039] A triggering structure 6 is installed on the support rod 401. The triggering structure 6 is used to drive the protective plate 5 to block or unblock the optical element. When the pin 402 is in the unblocked state, the triggering structure 6 forces the protective plate 5 to block the optical element. The unblocked state of the pin 402 is when it is not inserted into the soil. That is, when the device is idle or tilted, the pin 402 is pulled out of the soil. Through the cooperation of the triggering structure 6, the protective plate 5 is forced to slide upward, so that the protective plate 5 can protect the lens of the measuring device 3 in time. This allows the device to protect itself even when the observer is not available, increasing the practicality of the device.

[0040] Compared with the prior art, by installing a support rod 401 on the mounting plate 1 and inserting it into the ground with a pin 402, the triggering structure 6 will not be triggered when the pin 402 is inserted into the ground. When the pin 402 is not in the ground, it indicates that the device has tipped over. At this time, the triggering structure 6 drives the protection plate 5 to block the optical elements on the measuring device 3. Thus, when the device tipps over, the protection plate 5 protects the optical elements and reduces the possibility of damage to the device.

[0041] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the trigger structure 6 includes a mounting cavity 601 formed on the mounting plate 1, and an annular plate 602 is slidably mounted in the mounting cavity 601, so as to... Figure 1 From the main perspective, the ring plate 602 slides vertically within the mounting cavity 601;

[0042] A connecting spring 6013 is installed between the ring plate 602 and the mounting cavity 601. The connecting spring 6013 forces the ring plate 602 to move upward. A counterweight is installed on the mounting plate 1. When the support rod 401 opens, the counterweight pulls the ring plate 602 downward, causing the ring plate 602 to move downward. At this time, the connecting spring 6013 is in a stretched state.

[0043] The free end of the support rod 401 is hinged to a connecting plate 603. When the support rod 401 is unfolded, the connecting plate 603 is rotated to keep it parallel to the ground to be inserted, which makes it easier to insert the pin 402 into the soil later.

[0044] A contact plate 604 is slidably mounted on a connecting plate 603. An anti-collision spring 605 is installed between the contact plate 604 and the connecting plate 603. A channel is opened on the connecting plate 603. A through plate that slides through the channel is installed on the contact plate 604. An L-shaped plate is installed on the connecting plate 603. The anti-collision spring 605 is located between the L-shaped plate and the through plate. The anti-collision spring 605 forces the contact plate 604 away from the connecting plate 603. A pin 402 is installed on the contact plate 604. When the pin 402 is inserted into the soil, the weight of the device presses on the contact plate 604, forcing the contact plate 604 to contact the connecting plate 603. At this time, the anti-collision spring 605 is in a compressed state. When the device is tilted, the device tilts, the positive pressure applied to the contact plate 604 disappears, and the push of the anti-collision spring 605 to reset forces the contact plate 604 away from the connecting plate 603.

[0045] A pull rope 606 is installed on the contact plate 604 and mounted on the through plate. The pull rope 606 is a steel wire rope or hemp rope. A contact rod 607 for abutting against the ring plate 602 is slidably installed on the hinge end of the support rod 401. An arc-shaped plate is installed on the contact rod 607, located at the hinge end of the support rod 401, and the two are slidably connected. The pull rope 606 is connected to the contact rod 607. A torsion spring 608 is installed between the contact rod 607 and the support rod 401. The torsion spring 608 is a torsion spring. A cavity is opened on the support rod 401. The cavity is an annular cavity, and its center is concentric with the hinge point of the support rod 401. The free end of the torsion spring 608 passes through the cavity and is located on the outside, parallel to the arc of the contact rod 607. The shaped plate connection allows the sliding path of the abutment rod 607 to be a reciprocating arc motion along the arc surface of the free end of the support rod 401. When the support rod 401 is in the unfolded support state, the abutment rod 607 is in an inclined state compared to the vertical direction, and the pull rope 606 is in a relaxed state. When the pin 402 is in an unloaded state, the contact plate 604 is away from the connecting plate 603. At this time, the pull rope 606 is tightened, and then the pull rope 606 pulls the abutment rod 607, forcing it to slide to a position in the vertical direction. At this time, the abutment rod 607 pushes against the ring plate 602. The pushing of the abutment rod 607 and the pulling of the connecting spring 6013 counteract the counterweight, forcing the ring plate 602 to move upward.

[0046] The measuring device 3 is equipped with a housing 609, and a push spring 6010 connected to the protective plate 5 is installed inside the housing 609. The push spring 6010 forces the protective plate 5 to move outward from the housing 609. A trigger plate 6011 for shielding the protective plate 5 is slidably mounted on the housing 609. The trigger plate 6011 slides horizontally. The housing 609 has an opening, and the trigger plate 6011 is U-shaped, with one end inserted into the housing 609 through the opening, thereby shielding the protective plate 5. The protective plate 5 provides cover, the trigger plate 6011 has a force-bearing inclined surface, and the ring plate 602 is equipped with a push rod 6012 for abutting the trigger plate 6011. When the push rod 6012 abuts the trigger plate 6011, it forces the trigger plate 6011 to release the cover of the protective plate 5. When the push rod 6012 moves upward, it abuts the force-bearing inclined surface of the trigger plate 6011, thereby forcing the trigger plate 6011 to slide, so that its other end moves out from the opening to release the cover of the protective plate 5.

[0047] When the device is in use, pressing down on the protective plate 5 compresses the push spring 6010, and then sliding the trigger plate 6011 to block the protective plate 5. At this time, the protective plate 5, pushed by the push spring 6010, abuts against the trigger plate 6011, restricting the sliding of the trigger plate 6011 and preventing it from sliding arbitrarily under small external forces. The two act as a mutual lock. When the device is measuring normally, the pin 402 is inserted into the ground, and the device presses against the contact plate 604. Therefore, the abutment spring 605 is in a compressed state. When the device tilts, the pin 402 will inevitably separate from the ground. At this time, the abutment spring 605 pushes the contact plate 604 away from the connecting plate 603, and... This causes the pull rope 606 to become taut, which in turn pulls the abutment rod 607 to rotate to a position where it abuts the ring plate 602, lifting the ring plate 602 and the push rod 6012 upward. At this time, the push rod 6012 abuts the trigger plate 6011 through the force-bearing inclined surface, and through the guidance of the force-bearing inclined surface, forces the trigger plate 6011 to slide away from the housing 609, releasing the obstruction of the protective plate 5. The protective plate 5 is pushed by the push spring 6010, so that it completes the obstruction of the lens of the measuring device 3. While protecting the lens, the device triggers the protection mechanism by sensing whether the pin 402 is firmly inserted into the ground. Even if the observer reacts slowly, the lens of the measuring device 3 can still be protected.

[0048] When the device is measuring, the pin 402 is inserted into the ground → the weight of the device presses down the contact plate 604 → the abutment spring 605 is compressed → the pull rope 606 is relaxed → the abutment rod 607 deviates from the vertical position under the action of the torsion spring 608. This design not only prepares for triggering protection, but more importantly, under normal measurement conditions, the pull rope 606 is in a relaxed state. This effectively avoids the possibility that the pull rope 606 will accidentally tighten due to outdoor wind swaying, slight vibration, etc., and thus accidentally trigger the protection mechanism, i.e., drive the protection plate 5 to block the lens. This improves the system's anti-interference ability and the stability of the measurement process.

[0049] like Figure 9 and Figure 11 As shown, in some embodiments, a first lever 7, a second lever 8, and a third lever 9 are rotatably mounted within the mounting cavity 601. Each lever has a force-applying end and a force-receiving end. The force-receiving end of the first lever 7 contacts the actuating rod 6012, and the force-applying end contacts the force-receiving end of the second lever 8. The force-receiving end of the first lever 7 is shorter than the force-applying end. The force-applying end of the second lever 8 contacts the force-receiving end of the third lever 9. A hinge block 10 is hinged to the force-applying end of the third lever 9. An annular plate 11 is slidably mounted on the mounting plate 1, and the annular plate 11 is slidably connected to the hinge block 10. The annular plate 11 has a force-applying inclined surface parallel to the force-receiving inclined surface on the trigger plate 6011. The first lever 7, the second lever 8, and the third lever 9 are all installed at an angle... Figure 9 As shown, when the jacking rod 6012 pushes against the force-bearing end of the first lever 7, its force-applying end also pushes against the force-bearing end of the second lever 8, forcing its force-bearing end to rotate away from the third lever 9. This forces the force-applying end of the second lever 8 to rotate closer to the third lever 9 and push against the force-bearing end of the third lever 9, thus forcing the force-applying end of the third lever 9 to rotate vertically. This, in turn, lifts the hinge block 10, indirectly pushing the annular plate 11. Both the first lever 7 and the third lever 9 are levers that require more effort. Leveraging levers saves distance, even if the annular plate 602 rises a small distance, the amplification between the two levers allows the third lever 9 to push the annular plate 11 a sufficiently long distance, forcing the annular plate 11 to push against the contact plate 604. By having the annular plate 11 push against the contact plate 604, the contact plate 604 remains in contact regardless of the angle to which the measuring device 3 rotates in the horizontal direction, increasing the feasibility of the device.

[0050] The contact plate 604 includes an outer shell and an inner plate, with the inner plate slidably connected to the outer shell. The inner plate includes two hinged plates, with a force-bearing inclined surface on the lower hinge plate. The hinge point of the two plates is connected by a rotating rod, which has a threaded connection for a nut. The threaded nut is not shown in the accompanying drawings for clarity of the remaining structure. When the nut rotates to contact the hinge plate, it restricts the rotation of both plates. This allows the measuring device 3 to maintain contact with the annular plate 11 by sliding the inner plate and rotating the hinge plate during vertical adjustment. The threaded nut further restricts the rotation of the hinge plate. When the annular plate 11 contacts it, the hinge plate can smoothly transmit the force, allowing the contact plate 604 to smoothly release the obstruction of the protective plate 5, increasing the feasibility of the device. Through the amplification effect of the first lever 7 and the third lever 9, the final lifting stroke of the annular plate 11 is large enough. This ensures that no matter what angle the measuring device 3 is adjusted to in the vertical direction, the contact plate 604, especially its adjustable inner plate, always has enough space to adjust to the position of contact with the annular plate 11 by sliding and rotating. This ensures that the automatic protection function can be reliably triggered under any measuring posture, greatly enhancing the adaptability and reliability of the device.

[0051] like Figure 11 As shown, in some embodiments, an extension rod 12 is mounted on the rotating shaft of the flat rotating plate 201, and a wedge block 13 is mounted on the extension rod 12. A plurality of wedge grooves 14 for accommodating the wedge blocks 13 are formed on the annular plate 602. The wedge grooves 14 are arranged in a ring array around the center of the annular plate 602. When the abutting rod 607 abuts against the annular plate 602, the wedge grooves 14 accommodate the wedge blocks 13. When the device is measuring, the counterweight forces the annular plate 602 to slide downwards. At this time, there is a gap between the wedge blocks 13 and the annular plate 602, and the wedge blocks 13 will not be inserted into the wedge grooves 14, thus not affecting the rotation of the flat rotating plate 201. However, when the device tilts, the abutting rod... 607 pushes the ring plate 602 upward, so that the wedge block 13 can be inserted into the wedge groove 14. The inner wall of the wedge groove 14 blocks the side wall of the wedge block 13, restricting the rotation of the flat rotating plate 201. This reduces the possibility of the measuring device 3 rotating randomly when the device is tilted, and reduces the range of motion of the measuring device 3 when tilted. At the same time as triggering the lens protection, the horizontal rotation axis is automatically locked. This prevents the measuring device 3 and its heavy GPS component from swinging violently due to inertia during the tilting and rolling process, thereby impacting or damaging the components of the flat rotating plate 201, extending the service life of the core adjustment components, and further increasing the protection effect of the measuring device 3.

[0052] When the device is in use: the support rod 401 unfolds → the collar 15 slides down → the counterweight 17 falls and presses down on the sliding block 1501 → the ring plate 602 is pulled down → the wedge block 13 disengages from the wedge groove 14 → the flat rotating plate 201 can rotate freely, forming an interlocked operating sequence. Only when the support is fully unfolded and stabilized by the counterweight is the horizontal rotation adjustment function of the measuring device unlocked. This forces the observer to stably support the entire device before adjusting the measurement angle, avoiding the risk of tipping caused by forced adjustment when the support is unstable, and cultivating safe operating habits.

[0053] like Figure 7 As shown, in some embodiments, a sliding rod 27 is mounted on the mounting plate 1, and a collar 15 is slidably mounted on the sliding rod 27. A hinge rod 16 is hinged to the collar 15, and the free end of the hinge rod 16 is hinged to the support rod 401. The collar 15, the hinge rod 16, and the support rod 401 form an umbrella-like structure. When the device is idle, the collar 15 is located at the top of the sliding rod 27. When the support rod 401 needs to be unfolded, the collar 15 is slid downwards, causing the hinge rod 16 to rotate and unfold, while also pulling the support rod 401 outwards. In use, the collar 15 and the hinge rod 16 increase the support points of the support rod 401, thereby increasing the stability of the device during measurement.

[0054] like Figure 7 As shown, in some embodiments, the sliding rod 27 has a cavity communicating with the mounting cavity 601, a counterweight 17 is mounted on the ring plate 602, and a sliding block 1501 is mounted on the collar 15. The sliding rod 27 has a through groove 1502 for accommodating the sliding block 1501. The counterweight 17 is used to press the sliding block 1501. The counterweight 17 is the aforementioned counterweight component. When the device is stored, the sliding block 1501 on the collar 15 pushes the counterweight 17 upward, so that the ring plate 602 is in the upper position. When the device needs to measure, the bracket is... When rod 401 is extended, as collar 15 slides downward, counterweight 17 also slides downward due to gravity, pulling ring plate 602 downward. By pressing down on sliding block 1501, collar 15 is held in place, limiting its upward movement and increasing the stability of collar 15 during use. If collar 15 cannot slide, hinge rod 16 cannot rotate. If hinge rod 16 cannot rotate, support rod 401 cannot be retracted, reducing the possibility of support rod 401 being stored during use due to complex outdoor environments, and further increasing the stability of the device.

[0055] like Figure 6As shown, in some embodiments, a handle 18 is installed on the side wall of the protective plate 5, and a long slot 19 for accommodating the handle 18 is provided on the housing 609. The long slot 19 forces the interior of the housing 609 to communicate with the outside, thereby causing the handle 18 to be located on the outside. When the protective plate 5 is pressed down, the handle 18 provides a gripping point for the observer, which is convenient for operation and increases the practicality of the device.

[0056] like Figure 5 As shown, in some embodiments, a worm gear 20 is mounted on the shaft of the vertical turntable 202, and a hollow circular plate 21 is rotatably mounted on the mounting plate 1. The hollow circular plate 21 is annular, and a worm 22 that meshes with the worm gear 20 is rotatably mounted on the hollow circular plate 21. When the horizontal turntable 201 rotates, the worm 22 can also rotate with the hollow circular plate 21, so that the worm 22 can maintain meshing with the worm gear 20. When adjusting the vertical direction of the measuring device 3, the adjustment is made through the transmission of the worm gear 20 and the worm 22. Because the two have a self-locking function, the vertical turntable 202 is naturally prevented from falling. When linked with the horizontal rotation lock, in the protected state, the adjustment functions of the measuring device 3 in both the horizontal and vertical dimensions are effectively fixed. This minimizes the relative displacement and collision of the internal optical and electronic components of the device caused by tilting and rolling, and provides a buffering and fixing effect on the entire internal structure of the measuring device beyond lens protection, further reducing the possibility of damage to the measuring device 3.

[0057] like Figure 2 and Figure 6As shown, in some embodiments, a plate 23 is installed on the vertical turntable 202, and a slot 2301 is provided on the plate 23. A disassembly plate 2302 for insertion into the slot 2301 is installed on the measuring device 3. A compression spring 2303 is installed in the slot 2301, and a limiting plate 2304 for blocking the disassembly plate 2302 is installed on the free end of the compression spring 2303. The limiting plate 2304 has a bevel on the side facing the opening of the slot 2301. When the device is in use, the disassembly plate 2302 is aligned with the slot 2301 and inserted into the slot 2301. The bevel on the limiting plate 2304 causes the limiting plate 2304 to be pressed downward, so that the limiting plate 2304 releases the blocking of the disassembly plate 2302. After the disassembly plate 2302 passes the limiting plate 2304, it is inserted into the innermost part of the slot 2301. At this point, the compression spring 2303 forces the limiting plate 2304 to reset. The side of the limiting plate 2304 facing the inside of the slot 2301 is flat. At this point, the disassembly plate 2302 cannot simply slide the limiting plate 2304 to make way for it. The above setting allows the measuring device 3 to be disassembled, so that it can be disassembled and transported separately, reducing the possibility of damage during transport and increasing the reliability of the device. In harsh field environments, if extreme weather (such as strong winds) is predicted or an emergency evacuation is required, the observers can quickly disassemble the core measuring device 3 from the support and put it into a protective box for separate storage, while the heavy support structure can be temporarily left in place or disposed of separately. This "rapid separation of core and carrier" design improves the survivability and portability of the valuable measuring unit in emergencies.

[0058] like Figure 4 and Figure 6 As shown, in some embodiments, the insert plate 23 is rotatably mounted on the vertical turntable 202. The insert plate 23 has a groove 24 for accommodating the limiting plate 2304. One side of the groove 24 has an opening communicating with the outside. An external plate 25 is mounted on the limiting plate 2304, slidingly engaging with the opening. A support block 26 is mounted on the vertical turntable 202 to abut against the external plate 25. When the insert plate 2302 presses against the limiting plate 2304 during installation, it retracts downwards into the groove 24, allowing the limiting plate 2304 to communicate with the outside. Pressing the outer plate 25 forces it to slide down into the groove 24 again, making the disassembly plate 2302 easier to remove and increasing the convenience of the device. After the measuring device 3 is installed, rotate the insert plate 23 to align the outer plate 25 with the support block 26. The support block 26 restricts the downward movement of the outer plate 25, reducing the possibility that the limiting plate 2304 may be accidentally touched and restrict the disassembly plate 2302 when the device is measuring, thus increasing the feasibility of the device.

[0059] Among them, the outer plate 25 and the support block 26 are equipped with frame plates, such as Figure 1 and 6As shown, after the frame plate accommodates both, it restricts the rotation of the insert plate 23, thereby reducing the impact of accidental rotation of the insert plate 23 on the measurement results.

[0060] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
