Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surveying and mapping systems, in particular to a wetland land surveying and mapping support system based on a multi-angle rotating structure. BACKGROUND

[0002] Land surveying and mapping is the core foundation of land resource investigation, planning and management, and as a special ecological unit, wetlands have complex topography and geomorphology, low surface bearing capacity and high humidity and rotting environment, which puts high requirements on the stability, adaptability and precision of surveying and mapping equipment. The application of existing surveying and mapping supports in wetland scenes has the following technical limitations: The surface matrix of wetlands is mainly composed of silt soil and peat soil. The particles of such soil are loose and have a very high water content, which results in a serious lack of bearing capacity. The legs of conventional surveying and mapping supports are generally designed with sharp feet or small-diameter round pad, which makes the contact area between the legs and the surface small. Under the action of the overall weight of the instrument and the support, the local pressure generated by the legs on the wetland surface significantly exceeds the bearing limit of the soil, which easily causes the legs to sink rapidly and directly destroys the basic support conditions for surveying and mapping operations. Although some surveying and mapping supports attempt to increase the contact area by adding simple pads, there is no effective fixed connection structure between the pads and the legs. In the wetland environment, the pads and the legs are easily relative to each other under the influence of factors such as slight surface deformation and water flow scouring, which cannot form a sustained and stable support system, and further causes the instrument attitude to deviate during the surveying and mapping process, resulting in a deviation in the precision of the surveying and mapping data.

DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings of the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0018] The present application will be further described below in connection with the embodiments.

[0019] Embodiment: Please refer to Figures 1-8 The present application provides a technical solution: a wetland national land surveying and mapping support system based on a multi-angle rotating structure, comprising: A mounting seat 1, the edge of the lower end of the mounting seat 1 is uniformly rotationally connected with a supporting mechanism 3 through a connecting seat 2, and the lower end of the mounting seat 1 is connected with a locking mechanism 4; Among them, the supporting mechanism 3 includes a round rod 31 fixedly connected to the lower end of the connecting seat 2 in symmetry, the lower ends of the two round rods 31 are commonly rotationally connected with a limiting seat 32, the limiting seat 32 is slidingly connected with a supporting leg 33, the lower end of the supporting leg 33 is fixedly connected with a ground anchor 34, the ground anchor 34 is connected with a grounding assembly 35 for improving stability, the lower end of the round rod 31 is eccentrically fixedly connected with an abutting rod 36, the limiting seat 32 is symmetrically slidingly connected with an abutting block 37, the abutting block 37 is preferably made of rubber material, for increasing the friction between the abutting block 37 and the supporting leg 33; The locking mechanism 4 comprises a mounting pipe 41 fixedly connected at the center of the lower end of the mounting seat 1, an adjusting seat 42 rotatably connected to the mounting pipe 41, and an adjusting assembly 43 connected to the adjusting seat 42. During installation, the adjusting assembly 43 drives the round rod 31 to rotate to control the locking of the supporting legs 33 and the folding and unfolding of the grounding assembly 35. The upper end of the mounting pipe 41 is fixedly sleeved with a hinged seat 38, and the three connecting seats 2 are hingedly connected to the hinged seat 38 through rotating plates.

[0020] Specifically, the surveying and mapping directly as a whole is in a folded state during transportation and carrying. At this time, the length direction of the round rod 31 is consistent with the mounting pipe 41, the overall volume is reduced, and the surveying and mapping personnel can move and transport in the complex terrain of wetlands.

[0021] After arriving at the surveying and mapping point, first, the supporting legs 33 are slid along the limiting seats 32 to a height that meets the surveying and mapping operation requirements. Then, any one of the supporting legs 33 is rotated outward. Under the cooperative action of the hinged seat 38 and the rotating plate, the three supporting legs 33 can be synchronously deflected outward without the need for separate adjustment of the angles of the supporting legs 33. This not only significantly improves the installation efficiency, but also ensures that the deflection angles of the three supporting legs 33 are consistent, laying a foundation for the subsequent stability of the whole bracket.

[0022] After the supporting legs 33 are adjusted in place, the ground anchors 34 are inserted into the soil of the wetland. Then, the extension lengths of the supporting legs 33 are fine-tuned to preliminarily place the mounting seat 1 in a horizontal state. Thereafter, the adjusting assembly 43 is operated to drive the two symmetrical round rods 31 on the same mounting seat 1 to synchronously and reversely rotate. This action can realize double functions. On the one hand, the rotation of the round rod 31 drives the eccentrically connected abutting rod 36 to push the two rubber abutting blocks 37 to approach each other and tightly abut against the surface of the supporting leg 33. The rubber abutting block 37 can form a firm locking effect due to its excellent friction performance. Compared with the conventional mechanical hard locking method used by the supporting leg 33, the locking method can not only avoid the wear of the surface of the supporting leg 33 during the locking process, but also effectively prevent the supporting leg 33 from sliding during the operation, so the locking reliability is higher.

[0023] On the other hand, the rotation of the round rod 31 synchronously triggers the grounding assembly 35 to unfold and be inserted into the soil. By increasing the contact area between the bracket and the surface of the wetland, the local pressure is greatly reduced, avoiding the problem of the sinking of the supporting leg 33 caused by the small grounding area of the conventional surveying and mapping supporting leg 33 and the excessive local pressure on the soft soil of the wetland. This fundamentally reduces the risk of distortion of the surveying and mapping accuracy caused by the settlement of the bracket, and adapts to special working conditions with low bearing capacity of the wetland soil.

[0024] The adjusting assembly 43 comprises a connecting piece 431, the upper ends of the two symmetrical circular rods 31 are connected with the connecting piece 431 in sliding mode, the outer circumferential surface of the circular rod 31 is symmetrically provided with an inclined groove 432, the connecting piece 431 is fixedly connected with a columnar block 433 corresponding to the inclined groove 432, the corresponding columnar block 433 and the inclined groove 432 are connected in sliding mode, the three connecting pieces 431 are respectively hinged through spring seats 434 and lifting seats 435, and the lifting seat 435 is connected with the adjusting seat 42 in threaded mode.

[0025] The circular rod 31 is symmetrically provided with a mounting groove 311, the mounting groove 311 is symmetrically fixedly connected with a magnetic stripe 436, the upper end of the supporting leg 33 is symmetrically connected with a magnetic block 437 in sliding mode, and the inside of the supporting leg 33 is provided with a linkage module 438 connected with the magnetic block 437.

[0026] The linkage module 438 comprises a push strip 4381, the push strip 4381 is symmetrically arranged at the top of the supporting leg 33 and is fixedly connected with the two magnetic stripes 436 respectively, the ends of the two magnetic stripes 436 away from each other are magnetically opposite, the two push strips 4381 are commonly connected with a scissor plate group 4383 through two rows of symmetrically distributed sliding seats 4382, the uppermost two sliding seats 4382 are fixedly connected with the push strip 4381 respectively, and the remaining sliding seats 4382 are connected with the push strip 4381 in sliding mode.

[0027] The lower ends of the two symmetric sliding seats 4382 at the lowermost position are fixedly connected with push rods 4384, the lower ends of the two push rods 4384 are commonly connected with a connecting block 4385, the lower end of the connecting block 4385 is fixedly connected with a connecting plate, and the lower end of the connecting plate is fixedly connected with a traction block 4386.

[0028] Specifically, in the initial state, the adjusting assembly 43 and the linkage module 438 are in a preset storage state: the magnetic block 437 and the magnetic stripe 436 close to one side of the supporting leg 33 are attracted to each other due to the magnetic repulsion, under the action of the attraction, the two push strips 4381 are distributed in a state of moving away from each other, thereby making the scissor plate group 4383 maintain a vertical folding mode, at this time, the sliding seats 4382 at the upper and lower positions on the same straight line are close to each other, the lowermost sliding seat 4382 is at a relatively high height due to the small distance between the adjacent sliding seats 4382, the push rod 4384 and the connecting block 4385 are synchronously maintained at a high position through the traction effect, the connecting block 4385 drives the traction block 4386 in the supporting leg 33 to a relatively high position through the connecting plate, and finally the grounding assembly 35 is in a folding storage state under the constraint of the traction block 4386.

[0029] When the legs 33 are opened and the ground anchors 34 are inserted into the soil, the adjusting seat 42 is rotated, and since the legs 33 and the spring seat 434 are kept stationary, the rotating movement of the adjusting seat 42 is converted into the descending movement of the lifting seat 435 through threaded transmission, and when the lifting seat 435 descends, the three connecting pieces 431 are synchronously pulled downward along the circular rods 31 through the spring seat 434, and in the downward movement of the connecting pieces 431, the cylindrical blocks 433 fixed on the surfaces thereof slide along the inclined grooves 432 on the circumferential outer surfaces of the circular rods 31, thereby driving the circular rods 31 to rotate; since the inclined grooves 432 on the symmetric circular rods 31 are symmetrically arranged, the two symmetric circular rods 31 can be synchronously and reversely rotated by one hundred and eighty degrees, compared with the conventional adjusting assembly 43 which needs to separately drive each component to rotate, this structure can ensure the consistency of the actions of the symmetric components without additional calibration, greatly improving the adjusting efficiency and synchronization accuracy.

[0030] With the synchronous and reverse rotation of the circular rods 31 by one hundred and eighty degrees, another magnetic stripe 436 in the mounting groove 311 of the circular rod 31 switches to a position close to the magnetic blocks 437 on the legs 33, since the magnetic stripe 436 and the close end of the magnetic blocks 437 have the same magnetism, the two magnetic blocks 437 synchronously approach each other under the magnetic repulsion, thereby driving the push strips 4381 connected thereto to synchronously approach, and in the approaching process of the push strips 4381, the scissor plate group 4383 is gradually converted from the vertical folded state to the vertical unfolded state, and in this process, compared with the conventional mechanical hard connection transmission, the magnetic control driving mode has no direct contact wear, can effectively prolong the service life of the components, and has more sensitive response.

[0031] When the scissor plate group 4383 is unfolded, the distance between the adjacent sliding seats 4382 gradually increases with the unfolding degree, and the two symmetric sliding seats 4382 at the lowest level synchronously descend in the legs 33, and the connecting blocks 4385 are pushed downward by the push rods 4384, and the connecting blocks 4385 drive the traction blocks 4386 to move downward in the legs 33 through the connecting plates, and finally the traction constraint of the grounding assembly 35 is released, so that the grounding assembly 35 is unfolded and inserted into the soil.

[0032] The linkage module 438 realizes power transmission through the expansion and contraction of the scissor plate group 4383, compared with the conventional pull rod type transmission, the stress of the scissor structure is more uniform, which can ensure the smooth downward movement of the traction block 4386 and avoid the problem that the grounding assembly 35 is not completely unfolded due to transmission jam, thereby reliably realizing the function of increasing the grounding area, further preventing the ground anchor 34 from sinking, and strengthening the overall stability of the support, and the folding and storage of the scissor plate group 4383 in the vertical direction can bring a longer stretching stroke, which is suitable for the long strip-shaped installation environment inside the legs 33, thereby meeting the longitudinal stroke required for the unfolding and storage of the grounding assembly 35.

[0033] The ground assembly 35 comprises a support plate 351 which is designed in L shape and is rotationally connected to the ground anchor 34 through the shorter linear segment thereof, and the lower end of the longer linear segment of the support plate 351 is fixedly connected with an insertion plate 352, and the longer linear segment of the support plate 351 is hingedly connected with the traction block 4386 through a short plate.

[0034] Specifically, when the support is in the initial storage and carrying transfer stage, since the lowermost sliding seat 4382 is at a relatively high position, the traction block 4386 is also located at a high position inside the support leg 33 under the driving of the connecting plate, at this time, the short plate forms traction on the L-shaped support plate 351, so that the longer linear segment thereof is closely attached to the surface of the support leg 33, and the bottom insertion plate 352 is stored inside. Compared with the conventional exposed ground assembly, this storage design can effectively avoid damage to the insertion plate 352 due to collision during carrying, or cause safety hazards such as scratches to the operator, thereby improving the safety and convenience of carrying the equipment.

[0035] When the support enters the installation stage, the traction block 4386 slides downward along the support leg 33 under the pushing of the connecting plate, and the L-shaped support plate 351 is driven to rotate around the ground anchor 34 through the short plate, so that the longer linear segment thereof is gradually turned from the state of being attached to the support leg 33 to the state of being closely attached to the ground. Compared with the conventional flat ground assembly, this L-shaped structure design can significantly increase the contact area with the ground after being closely attached to the ground, thereby reducing the local pressure of the support on the soft soil of the wetland, effectively relieving the settlement problem; at the same time, the insertion plate 352 inserted into the soil synchronously with the rotation of the support plate 351 can further enhance the engagement degree of the support and the soil, improve the grip performance, in addition, the L-shaped support plate 351 in the inclined state after rotation can play a supporting role similar to a reinforcing rib, compared with the conventional ground assembly 35 without reinforcing structure, it can effectively improve the bending resistance of the support leg 33, and further strengthen the overall stability of the support.

[0036] After the installation of the support is completed, its stress system forms a stable balance state: the spring seat 434 at the top continuously applies an inward traction force to the top of the round rod 31 through the connecting piece 431, and then acts on the top end of the support leg 33; and at the lower end of the support leg 33, since the support leg 33 is arranged outwardly inclined, the traction block 4386 is pressed against the support plate 351 through the short plate under the pushing of the connecting plate, while applying an outward pushing force to the lower end of the support leg 33. Compared with the conventional single support stress structure, this bidirectional stress mode of "inward traction at the top end and outward pushing at the lower end" can make the support leg 33 form a more stable stress balance, greatly enhance the overall anti-overturning ability of the support, and make it have good wind resistance, which can adapt to the complex wind environment of the wetland.

[0037] It is worth noting that the wetland national land surveying and mapping support system based on the multi-angle rotating structure has the following advantages: Advantage one, in the transportation stage, the length direction of the round rod 31 is consistent with the installation pipe 41, the support is in a folded state as a whole, the volume is greatly reduced, the surveying personnel can easily carry the support in the complex terrain of wet and muddy land and dense vegetation, after reaching the surveying point, the angle of each support leg 33 does not need to be adjusted one by one, only needs to be rotated outward by holding any support leg 33, under the synergistic action of the hinge seat 38 and the rotating plate, the three support legs 33 can be simultaneously deflected outward, which can ensure that the deflection angles of the support legs 33 are consistent, lay a foundation for subsequent stable support, save the cumbersome steps of separately calibrating the angle of the conventional support, and significantly improve the installation efficiency.

[0038] Advantage two, after the local anchor 34 is inserted into the soil and the installation seat 1 is adjusted to be substantially horizontal, the adjusting assembly 43 is operated to drive the two symmetrical round rods 31 on the same installation seat 1 to be synchronously and reversely rotated, the eccentrically fixed abutting rod 36 at the lower end of the round rod 31 is rotated at the same time, the symmetrical rubber abutting blocks 37 in the limiting seat 32 are pushed to approach each other and tightly abut against the surface of the support leg 33. Compared with the conventional mechanical hard locking (such as bolt fastening), the rubber abutting blocks 37 form firm locking by virtue of high friction performance, which can not only avoid scratching and wearing of the surface of the support leg 33 by the metal parts in the locking process, but also can effectively prevent the support leg 33 from sliding under the support of the soft soil in the wet land, ensure the position stability of the support leg 33, and the operation is simpler.

[0039] Advantage three, when the round rod 31 is synchronously and reversely rotated by one hundred and eighty degrees, the magnetic strip 436 in the installation groove 311 is switched, the magnetic blocks 437 on the support legs 33 change from being attracted to each other to being repelled to each other, the repulsion pushes the magnetic blocks 437 to drive the push strips 4381 to approach each other, trigger the action of the linkage module 438; the push strips 4381 approach to drive the scissor plate group 4383 to gradually unfold from the vertical folded state, the distance between the adjacent sliding seats 4382 increases, the lowermost sliding seat 4382 drives the push rod 4384, the connecting block 4385 and the connecting plate to move downward synchronously, pushes the traction block 4386 to release the constraint on the grounding assembly 35; the L-shaped support plate 351 rotates around the local anchor 34, the longer straight section closely abuts against the ground to increase the grounding area, the lower end insertion plate 352 synchronously inserts into the soil to enhance the ground holding property, through dynamically expanding the grounding area, the local pressure of the support on the soil in the wet land is greatly reduced, the sinking of the support leg 33 caused by the small grounding area and large pressure of the conventional support being greater than the bearing limit of the soil is avoided, and the risk of distortion of the surveying precision is reduced.

[0040] Advantage four, after installation, the spring seat 434 at the top continuously applies an inward pulling force to the top of the round rod 31 through the connecting piece 431, which is transmitted to the top end of the supporting leg 33, and can offset the outward overturning force generated by the wind at the top of the support, weakening the overturning tendency at the top; at the same time, because the supporting leg 33 is outwardly inclined, when the traction block 4386 is pressed by the short plate against the L-shaped supporting plate 351, an outward pushing force is applied to the lower end of the supporting leg 33, which acts on the outside of the grounding end of the supporting leg 33, forming an anti-overturning torque opposite to the direction of the overturning torque. This two-way force system of "pulling inward at the top and pushing outward at the lower end" can more actively resist the overturning risk caused by wind than the conventional support which only relies on the weight and soil friction to resist wind, and can ensure the stability of the support in the wetland outdoor windy environment.

[0041] Advantage five, the magnetic block 437 does not need to be directly connected with the magnetic strip 436 for driving, which avoids the friction loss between components compared with the conventional mechanical hard connection transmission such as gears and pull rods, and reduces the rust probability of metal components in the high-humidity environment of wetlands, prolonging the service life; the scissor plate group 4383 in the linkage module 438 realizes expansion and contraction through the cooperation of the sliding seat 4382 and the push bar 4381, and the stress is uniform during transmission, which can ensure the smooth downward movement of the traction block 4386 and avoid the jamming and locking problems of the conventional pull rod type transmission. Even in the case of decreased lubricity of components caused by high humidity in wetlands, the grounding assembly 35 can still be smoothly deployed and stored, ensuring the stability of the support function.

[0042] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
