Description

Technical Field

[0001] This invention relates to the field of surveying and mapping system technology, and specifically to a wetland land surveying support system based on a multi-angle rotation structure. Background Technology

[0002] Land surveying is the core foundation for land resource investigation, planning, and management. Wetlands, as special ecological units, have complex topography, low surface carrying capacity, and a humid and decomposed environment, which places stringent requirements on the stability, adaptability, and accuracy of surveying equipment. The application of existing surveying supports in wetland scenarios has the following technical limitations:

[0003] The surface substrate of wetlands is mainly composed of silty soil and peat soil. These soils are loosely granulated and have extremely high water content, resulting in a severe lack of bearing capacity. Conventional surveying rigs generally use pointed feet or small-diameter round pads for their legs, which reduces the contact area between the legs and the ground. Under the weight of the instrument and the rig, the local pressure exerted by the legs on the wetland surface significantly exceeds the soil's bearing capacity, easily causing the legs to sink rapidly and directly damaging the basic support conditions for surveying operations. Although some surveying rigs attempt to increase the ground contact area by adding simple pads, there is no effective fixed connection structure between the pads and the legs. In the wetland environment, due to factors such as slight surface deformation and water erosion, the pads and legs are prone to relative sliding, failing to form a continuous and stable support system. This leads to instrument attitude deviation during surveying, ultimately causing deviations in the accuracy of the surveying data. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a wetland land surveying support system based on a multi-angle rotation structure. This system effectively solves the problems of loose wetland soil with high water content and weak load-bearing capacity, small contact area of ​​conventional surveying support legs leading to local pressure exceeding soil limits and easy subsidence and damage to the support, and the lack of effective fixation between the simple pads added to some supports and the legs, which easily leads to slippage and instrument attitude deviation, affecting surveying accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a wetland land surveying support system based on a multi-angle rotation structure, comprising:

[0007] The mounting base has a support mechanism that is rotatably connected to the lower edge of the mounting base via a connecting seat, and a locking mechanism is connected to the lower end of the mounting base.

[0008] The support mechanism includes round rods symmetrically fixedly connected to the lower end of the connecting seat. The lower ends of the two round rods are rotatably connected to a limiting seat. A support leg is slidably connected to the limiting seat. A ground anchor is fixedly connected to the lower end of the support leg. A grounding component to improve stability is connected to the ground anchor.

[0009] The locking mechanism includes a mounting tube, which is fixedly connected to the center of the lower end of the mounting base. An adjusting seat is rotatably connected to the mounting tube, and an adjusting component is connected to the adjusting seat. During installation, the adjusting component drives the round rod to rotate, thereby controlling the locking of the outrigger and the retraction and extension of the grounding component.

[0010] Furthermore, the adjustment assembly includes a connector, with the upper ends of two symmetrical round rods slidably connected to the connector. The outer circumference of the round rods is symmetrically provided with inclined grooves. A cylindrical block corresponding to the inclined groove is fixedly connected to the connector. The corresponding cylindrical block and the inclined groove are slidably connected. The three connectors are respectively hinged to the lifting seat through spring seats. The lifting seat is connected to the adjustment seat through threads.

[0011] Furthermore, the round rod is symmetrically provided with mounting grooves, and magnetic strips are symmetrically fixedly connected in the mounting grooves. The ends of the two magnetic strips that are far apart from each other have opposite magnetic properties. Magnetic blocks are symmetrically slidably connected to the upper end of the support leg, and a linkage module connected to the magnetic blocks is provided inside the support leg.

[0012] Furthermore, the linkage module includes push bars, which are symmetrically arranged on the top of the support legs and fixedly connected to the two magnetic blocks respectively. The two push bars are connected to a scissor plate assembly through two rows of symmetrically distributed slides. The two uppermost slides are fixedly connected to the push bars respectively, and the remaining slides are slidably connected to the push bars.

[0013] Furthermore, the two symmetrical slides at the bottom are each fixedly connected to a push rod at their lower ends. The lower ends of the two push rods are connected to a connecting block. The lower end of the connecting block is fixedly connected to a connecting plate, and the lower end of the connecting plate is fixedly connected to a traction block.

[0014] Furthermore, the grounding assembly includes a support plate, which adopts an L-shaped design and is rotatably connected to the ground anchor through its vertical section. The lower end of the longer straight section of the support plate is fixedly connected to an insert plate, and the longer straight section of the support plate is hinged to the traction block through a short plate.

[0015] Furthermore, the lower end of the round rod is eccentrically fixedly connected to a stop rod, and a stop block is symmetrically slidably connected within the limiting seat.

[0016] Furthermore, a hinge seat is fixedly sleeved on the upper end of the mounting tube, and the three connecting seats are respectively hinged to the hinge seat through a rotating plate.

[0017] The technical solution provided by this invention has the following advantages compared with the prior art:

[0018] 1. In this invention, after the local anchor is inserted into the soil and the mounting base is adjusted to be approximately horizontal, the operating adjustment component drives two symmetrical round rods on the same mounting base to rotate synchronously in opposite directions. The abutment rods fixed eccentrically at the lower end of the round rods rotate together, pushing the symmetrically sliding rubber abutment blocks in the limiting seat to approach each other and tightly abut against the surface of the outrigger. Compared with conventional mechanical hard locking, the rubber abutment blocks form a firm lock due to their high friction performance, which not only avoids scratches and wear on the surface of the outrigger by metal parts during the locking process, but also effectively prevents the outrigger from sliding under the support of soft soil in wetland, ensuring the stability of the outrigger position, and making the operation simpler.

[0019] 2. In this invention, when the round rod rotates synchronously in the opposite direction by 180 degrees, the magnetic strip in the mounting slot switches, changing from attraction between opposite poles to repulsion between like poles with the magnetic block on the support leg. The repulsive force pushes the magnetic block to drive the push bar to move closer to each other, triggering the linkage module to act. The push bar moves closer to drive the scissor plate assembly to gradually unfold from a vertically folded state, increasing the distance between adjacent slides. The lowest slide drives the push rod, connecting block, and connecting plate to move down synchronously, pushing the traction block to release the constraint on the grounding component. The L-shaped support plate then rotates around the ground anchor, with the longer straight section pressed against the ground to increase the grounding area. The lower insertion plate is inserted into the soil to enhance grip. By expanding the grounding area, the local pressure of the support on the wetland soil is greatly reduced, avoiding the support leg sinking caused by the small grounding area and pressure exceeding the soil bearing capacity of conventional supports, thus reducing the risk of distortion in surveying accuracy.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0031] The present invention will be further described below with reference to embodiments.

[0032] Example

[0033] Please see Figures 1-8 This invention provides a technical solution: a wetland land surveying support system based on a multi-angle rotation structure, comprising:

[0034] Mounting base 1, the lower edge of the mounting base 1 is evenly rotatably connected to the support mechanism 3 through the connecting base 2, and the lower end of the mounting base 1 is connected to the locking mechanism 4.

[0035] The support mechanism 3 includes two round rods 31 symmetrically fixedly connected to the lower end of the connecting seat 2. The lower ends of the two round rods 31 are rotatably connected to a limiting seat 32. A support leg 33 is slidably connected to the limiting seat 32. A ground anchor 34 is fixedly connected to the lower end of the support leg 33. A grounding component 35 for improving stability is connected to the ground anchor 34. A stop rod 36 is eccentrically fixedly connected to the lower end of the round rod 31. A stop block 37 is symmetrically slidably connected inside the limiting seat 32. The stop block 37 is preferably made of rubber to increase the friction between it and the support leg 33.

[0036] The locking mechanism 4 includes a mounting tube 41, which is fixedly connected to the center of the lower end of the mounting base 1. An adjusting seat 42 is rotatably connected to the mounting tube 41, and an adjusting component 43 is connected to the adjusting seat 42. During installation, the adjusting component 43 drives the round rod 31 to rotate, thereby controlling the locking of the support leg 33 and the retraction and extension of the grounding component 35. A hinge seat 38 is fixedly sleeved on the upper end of the mounting tube 41, and the three connecting seats 2 are respectively hinged to the hinge seat 38 through a rotating plate.

[0037] Specifically, the surveying and mapping equipment is folded during transportation and carrying. At this time, the length of the round rod 31 is consistent with that of the installation tube 41, reducing the overall volume and making it easier for surveyors to move and transport the equipment in complex wetland terrain.

[0038] Upon reaching the survey point, first slide the support leg 33 along the limiting seat 32 to a height that meets the requirements of the surveying operation. Then, hold any one of the legs 33 and rotate it outward. With the coordinated action of the hinge seat 38 and the rotating plate, the three support legs 33 can be deflected outward synchronously without the need to adjust the angle of each support leg 33 individually. This not only significantly improves the installation efficiency but also ensures that the deflection angles of the three are consistent, laying the foundation for the overall stability of the support in the future.

[0039] After the outriggers 33 are adjusted into place, the ground anchors 34 are inserted into the wet soil. Then, by fine-tuning the extension length of each outrigger 33, the mounting base 1 is initially placed in a horizontal position. After that, by operating the adjustment component 43, the two symmetrical round rods 31 on the same mounting base 1 are driven to rotate synchronously in opposite directions. This action can achieve a dual function: on the one hand, the rotation of the round rods 31 drives the eccentrically connected abutment rods 36 to push the two rubber abutment blocks 37 closer to each other and tightly abut against the surface of the outriggers 33. The rubber abutment blocks 37, with their excellent friction properties, can form a firm locking effect. Compared with the mechanical hard locking method used by conventional outriggers 33, it avoids wear on the surface of the outriggers 33 during the locking process and effectively prevents the outriggers 33 from sliding during operation, resulting in higher locking reliability.

[0040] On the other hand, the rotation of the round rod 31 synchronously triggers the grounding component 35 to unfold and insert into the soil. By increasing the contact area between the support and the wetland surface, the local pressure is greatly reduced, avoiding the problem of the conventional surveying support leg 33 sinking due to its small grounding area and excessive local pressure on the soft wetland soil. This fundamentally reduces the risk of surveying accuracy distortion caused by support settlement and is suitable for special working conditions with low wetland soil bearing capacity.

[0041] The adjustment assembly 43 includes a connector 431. The upper ends of two symmetrical round rods 31 are slidably connected to the connector 431. The outer circumference of the round rods 31 is symmetrically provided with inclined grooves 432. A cylindrical block 433 corresponding to the inclined groove 432 is fixedly connected to the connector 431. The corresponding cylindrical block 433 and the inclined groove 432 are slidably connected. The three connectors 431 are respectively hinged to the lifting seat 435 through spring seats 434. The lifting seat 435 is connected to the adjustment seat 42 through threads.

[0042] The round rod 31 is symmetrically provided with mounting grooves 311, and magnetic strips 436 are symmetrically fixedly connected in the mounting grooves 311. Magnetic blocks 437 are symmetrically slidably connected to the upper end of the support leg 33, and a linkage module 438 connected to the magnetic blocks 437 is provided inside the support leg 33.

[0043] The linkage module 438 includes push bars 4381, which are symmetrically arranged on the top of the support leg 33 and fixedly connected to the two magnetic blocks 437 respectively. The magnetic ends of the two magnetic bars 436 that are far apart from each other have opposite magnetic properties. The two push bars 4381 are connected to the scissor plate assembly 4383 through two rows of symmetrically distributed slide blocks 4382. The two uppermost slide blocks 4382 are fixedly connected to the push bars 4381 respectively, and the remaining slide blocks 4382 are slidably connected to the push bars 4381.

[0044] The two symmetrical slide blocks 4382 at the bottom are fixedly connected to the lower ends of push rods 4384. The lower ends of the two push rods 4384 are connected to a connecting block 4385. The lower end of the connecting block 4385 is fixedly connected to a connecting plate. The lower end of the connecting plate is fixedly connected to a traction block 4386.

[0045] Specifically, in the initial state, the adjustment component 43 and the linkage module 438 are in a preset storage state: the magnetic block 437 and the magnetic strip 436 near the support leg 33 attract each other due to their opposite magnetism. Under the action of this attraction, the two push bars 4381 are distributed in a state of distance from each other, thereby keeping the scissor plate assembly 4383 in a vertical folded state. At this time, the slides 4382, which are on the same straight line, are close to each other. The lower slide 4382 is at a higher height because the distance between adjacent slides 4382 is small. Through the traction of the push rod 4384 and the connecting block 4385, the two are synchronously maintained at a high position. The connecting block 4385 then drives the traction block 4386 to be in a relatively high position inside the support leg 33 via the connecting plate. Finally, the grounding component 35 is in a folded storage state under the constraint of the traction block 4386.

[0046] When the outrigger 33 opens and the ground anchor 34 is inserted into the soil, the adjusting seat 42 is rotated. Since the outrigger 33 and the spring seat 434 remain stationary, the rotational motion of the adjusting seat 42 is converted into the downward motion of the lifting seat 435 through the screw drive. When the lifting seat 435 descends, the spring seat 434 synchronously pulls the three connecting parts 431 to slide downward along the round rod 31. During the downward movement of the connecting parts 431, the cylindrical blocks 433 fixed on their surfaces slide along the inclined grooves 432 opened on the outer circumference of the round rod 31, thereby driving the round rod 31 to rotate. Because the inclined grooves 432 on the symmetrical round rods 31 are symmetrically arranged, the two symmetrical round rods 31 can achieve synchronous reverse rotation of 180 degrees. Compared with the conventional adjustment assembly 43, which requires each component to be driven to rotate separately, this structure can ensure the consistency of the symmetrical component's movement without additional calibration, greatly improving the adjustment efficiency and synchronization accuracy.

[0047] As the round rod 31 rotates 180 degrees in the opposite direction, another magnetic strip 436 in the mounting groove 311 of the round rod 31 switches to a position close to the magnetic block 437 on the support leg 33. Since the magnetic strip 436 and the magnetic block 437 have the same magnetism at the end that is close to each other, they generate magnetic repulsion. Under the action of repulsion, the two magnetic blocks 437 move closer to each other in sync, thereby driving the push bar 4381 connected to them to move closer in sync. During the process of the push bar 4381 moving closer, the drive scissor plate assembly 4383 gradually changes from a vertically folded state to a vertically unfolded state. In this process, compared with conventional mechanical hard connection transmission, the magnetic control drive method has no direct contact wear, which can effectively extend the service life of the components and is more responsive.

[0048] When the scissor lift assembly 4383 is deployed, the distance between adjacent slide blocks 4382 gradually increases as the deployment progresses. The two lowest symmetrical slide blocks 4382 decrease in height within the support leg 33 in sync. The push rod 4384 pushes the connecting block 4385 downward, and the connecting block 4385 then drives the traction block 4386 to move downward within the support leg 33 via the connecting plate. Finally, the traction constraint on the grounding component 35 is released, allowing the grounding component 35 to be deployed and inserted into the soil.

[0049] The linkage module 438 transmits power through the extension and retraction of the scissor plate assembly 4383. Compared with conventional lever-type transmission, the scissor structure distributes force more evenly, ensuring that the traction block 4386 moves smoothly downwards. This avoids the problem of incomplete unfolding of the grounding component 35 due to transmission jamming, thus reliably increasing the grounding area and further preventing the ground anchor 34 from settling, thereby enhancing the overall stability of the support. The folding and retraction of the scissor plate assembly 4383 in the vertical direction can provide a longer extension stroke, which is suitable for long and narrow installation environments such as inside the outrigger 33, thus meeting the longitudinal stroke required for the unfolding and retraction of the grounding component 35.

[0050] The grounding assembly 35 includes a support plate 351, which is L-shaped and rotatably connected to the ground anchor 34 through its shorter straight section. The lower end of the longer straight section of the support plate 351 is fixedly connected to an insert plate 352, and the longer straight section of the support plate 351 is hinged to the traction block 4386 through a short plate.

[0051] Specifically, during the initial storage and transport phase of the support frame, since the lowest slide 4382 is in a relatively high position, the traction block 4386, driven by the connecting plate, is also located in a high position inside the support leg 33. At this time, the short plate pulls on the L-shaped support plate 351, causing its longer straight section to fit tightly against the surface of the support leg 33, while the bottom insert plate 352 is retracted inside. Compared with conventional exposed grounding components, this storage design effectively avoids safety hazards such as damage to the insert plate 352 due to collisions or scratches to operators during transport, thus improving the safety and convenience of carrying the equipment.

[0052] When the support frame enters the installation stage, the traction block 4386 slides downward along the support leg 33 under the push of the connecting plate. This causes the L-shaped support plate 351 to rotate around the ground anchor 34 via the short plate, gradually flipping its longer straight section from a state of contact with the support leg 33 to a state of close contact with the ground. Compared to conventional flat grounding components, this L-shaped structure design significantly increases the contact area with the ground surface after close contact, thereby reducing the local pressure of the support frame on the soft soil of wetlands and effectively mitigating settlement problems. Simultaneously, the insertion plate 352, which is inserted into the soil synchronously with the rotation of the support plate 351, further enhances the interlocking force between the support frame and the soil, improving grip performance. Furthermore, the L-shaped support plate 351, tilted after rotation, acts as a reinforcing rib, effectively improving the bending resistance of the support leg 33 compared to conventional grounding components 35 without reinforcement, further strengthening the overall stability of the support frame.

[0053] After the support frame is installed, its force system forms a stable equilibrium: the top spring seat 434 continuously applies an inward traction force to the top of the round rod 31 through the connector 431, which in turn acts on the top of the support leg 33; while at the lower end of the support leg 33, since the support leg 33 is inclined outward, the traction block 4386, pushed by the connecting plate, presses the support plate 351 through the short plate, while simultaneously applying an outward pushing force to the lower end of the support leg 33. This bidirectional force-bearing mode of "inward traction at the top and outward pushing at the bottom" allows the support leg 33 to form a more stable force balance compared to the single support structure of conventional supports, greatly enhancing the overall anti-overturning ability of the support frame, giving it good wind resistance performance, and making it adaptable to the complex wind environment of wetlands.

[0054] It is worth noting that the aforementioned wetland land surveying support system based on a multi-angle rotation structure also has the following advantages:

[0055] Advantage 1: During transportation, the length of the round rod 31 is consistent with that of the installation pipe 41, and the entire bracket is folded, greatly reducing its volume. This makes it easier for surveyors to transport the bracket in complex terrains such as wetlands, mud, and dense vegetation. After arriving at the survey point, there is no need to adjust the angle of each leg 33 individually. Simply hold any one leg 33 and rotate it outward. With the coordinated action of the hinge seat 38 and the rotating plate, all three legs 33 can deflect outward synchronously. This ensures that the deflection angle of the legs 33 is consistent, laying the foundation for subsequent stable support. It also eliminates the tedious step of individually calibrating the angle of conventional brackets, significantly improving installation efficiency.

[0056] Advantage 2: After the local anchor 34 is inserted into the soil and the mounting base 1 is adjusted to a roughly horizontal position, the operating adjustment component 43 drives the two symmetrical round rods 31 on the same mounting base 1 to rotate synchronously in opposite directions. The abutment rods 36, which are eccentrically fixed at the lower end of the round rods 31, rotate together, pushing the symmetrically sliding rubber abutment blocks 37 inside the limiting seat 32 closer together and tightly abutting against the surface of the outrigger 33. Compared with conventional mechanical hard locking (such as bolt tightening), the rubber abutment blocks 37 form a firm lock due to their high friction performance. This not only avoids scratches and wear on the surface of the outrigger 33 by metal parts during the locking process, but also effectively prevents the outrigger 33 from sliding under the support of soft soil in wet areas, ensuring the stability of the outrigger 33's position, and making operation simpler.

[0057] Advantage 3: When the round rod 31 rotates 180 degrees in the opposite direction, the magnetic strip 436 in the mounting slot 311 switches, changing from attraction between opposite poles to repulsion between like poles with the magnetic block 437 on the support leg 33. The repulsive force pushes the magnetic block 437 to bring the push bar 4381 closer together, triggering the linkage module 438 to move. The push bar 4381 approaches and drives the scissor lift plate assembly 4383 to gradually unfold from a vertically folded state. The distance between adjacent slide blocks 4382 increases, and the lowermost slide block 4382 drives the push rod 4384 and the connecting block. 4385. The connecting plate moves down synchronously, pushing the traction block 4386 to release the constraint on the grounding component 35; the L-shaped support plate 351 rotates around the ground anchor 34, and the longer straight section is close to the ground to increase the grounding area. The lower end insertion plate 352 is inserted into the soil to enhance the grip. By dynamically expanding the grounding area, the local pressure of the support on the wetland soil is greatly reduced, avoiding the sinking of the legs 33 of the conventional support due to the small grounding area and the pressure exceeding the soil bearing limit, and reducing the risk of distortion of surveying accuracy.

[0058] Fourthly, after installation, the top spring seat 434 continuously applies an inward traction force to the top of the round rod 31 through the connector 431. This force is transmitted to the top of the support leg 33, which can counteract the outward overturning force generated by the wind at the top of the support, weakening the tendency of the top to overturn. At the same time, because the support leg 33 is inclined outward, when the traction block 4386 is pushed by the connecting plate and presses the L-shaped support plate 351 through the short plate, it applies an outward pushing force to the lower end of the support leg 33. This force acts on the outside of the ground end of the support leg 33, forming an anti-overturning moment opposite to the direction of the overturning moment. This two-way force system of "inward traction at the top and outward pushing at the bottom" can more actively resist the risk of overturning caused by wind than the conventional support that only relies on its own weight and soil friction to resist wind, ensuring the stability of the support in the windy environment of wetlands.

[0059] Fifthly, the drive of the magnetic block 437 and the magnetic strip 436 does not require direct contact. Compared with conventional mechanical hard-connection transmissions such as gears and levers, this avoids frictional loss between components and reduces the probability of metal parts rusting in wet and humid environments, thus extending service life. The scissor plate assembly 4383 in the linkage module 438 achieves extension and retraction through the cooperation of the slide block 4382 and the push bar 4381. The force is evenly distributed during transmission, which can ensure that the traction block 4386 moves down smoothly and avoids the jamming and jamming problems that are prone to occur in conventional lever transmissions. Even when the lubrication of components decreases due to high humidity in wet environments, the grounding component 35 can still be smoothly deployed and stored, ensuring the stability of the bracket function.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
