Description

Technical Field

[0001] The invention belongs to the technical field of land surveying, and specifically relates to a field measurement device for territorial space planning. Background Art

[0002] Land slope measurement is the process of determining the degree of surface inclination, which is crucial for fields such as territorial planning, architectural design, agricultural irrigation, and soil and water conservation. Land slope measurement often requires on-site measurement in the wild environment and the recording of on-site geomorphic features during the measurement process. Most existing slope measuring instruments complete the measurement by directly attaching a measuring plate to the surface of the slope and measuring the angle formed with the horizontal line. However, since most of the slopes in the wild are uneven, it is difficult for the measuring plate to fit evenly with the surface of the slope, resulting in an increase in the angular error measured by the surveyor and a decrease in the accuracy of slope measurement.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Most existing slope measuring instruments directly attach a measuring plate to the surface of the slope and then measure the angle it makes with the horizontal line. However, since most of the slopes in the wild are uneven, it is difficult for the measuring plate to fit evenly with the surface of the slope, resulting in an increase in the angular error measured by the surveyor and a decrease in the accuracy of slope measurement.

[0030] Embodiment 1: A field measurement device for territorial spatial planning, as Figures 1 - 4 shown, includes a base 101. A fitting frame 102 is rotatably connected to the right side of the base 101. A first steering gear 103 is fixedly connected to the front side of the fitting frame 102. The first steering gear 103 is a bevel gear. A rotating shaft 104 is rotatably connected to the front side of the base 101. A second steering gear 105 is fixedly connected to the right side of the rotating shaft 104. The second steering gear 105 is a bevel gear. The first steering gear 103 meshes with the second steering gear 105. The rotating shaft 104 causes the fitting frame 102 to deflect along the base 101 through the first steering gear 103 and the second steering gear 105. Ten first fixed cylinders 106 in a linear array are rotatably connected to the inner side of the fitting frame 102. First piston shafts 107 are hermetically and slidably connected in the ten first fixed cylinders 106 in the linear array. The first fixed cylinders 106 and the adjacent first piston shafts 107 cooperate to form a sealed cavity. First elastic elements 108 are provided between the ten first fixed cylinders 106 in the linear array and the adjacent first piston shafts 107 respectively. The first elastic elements 108 are springs. The first elastic elements 108 are used to drive the adjacent first piston shafts 107 to reset. Eight first piston shafts 107 in the middle of the linear array are rotatably connected to a first hinge plate 109 and a second hinge plate 110 respectively. The first piston shaft 107 at the top is only rotatably connected to the first hinge plate 109. The first piston shaft 107 at the bottom is only rotatably connected to the second hinge plate 110. The first hinge plate 109 on the first piston shaft 107 and the second hinge plate 110 on the adjacent first piston shaft 107 are slidably connected to adapt to the position change between two adjacent first piston shafts 107 and simultaneously show the slope of the slope between the two first piston shafts 107. A leveling component for adjusting the angle of the first fixed cylinder 106 is arranged outside the fitting frame 102. A triggering component for pushing the first piston shaft 107 is arranged on the upper plane of the base 101. A measuring component for measuring the slope of the first hinge plate 109 and the adjacent second hinge plate 110 is arranged outside the fitting frame 102. By dividing the area of the measured slope into nine small areas and showing the slopes of the nine small areas through the first hinge plate 109 and the second hinge plate 110, it is possible to avoid an increase in error during large-scale unified measurement due to the unevenness of the slope and reduce the measurement accuracy of the slope gradient.

[0031] As Figure 3 andFigure 4 As shown in the figure, the leveling component includes a first rack 111. The first rack 111 is slidably connected to the inner side of the fitting frame 102. Ten leveling gears 112 are fixedly connected to the outside of the ten first fixed cylinders 106 arranged in a linear array. The ten leveling gears 112 arranged in a linear array are all meshed with the first rack 111. The first rack 111 drives the adjacent first fixed cylinders 106 to rotate through the leveling gears 112, so that the first fixed cylinders 106 are in a horizontal state. The fitting frame 102 is threadedly connected with a limiting shaft 113. The limiting shaft 113 is in extrusion fit with the first rack 111. The limiting shaft 113 moves along the fitting frame 102 to extrude the first rack 111 and lock the first rack 111.

[0032] As Figure 1 and Figure 3 As shown in the figure, the triggering component includes a second fixed cylinder 201. The second fixed cylinder 201 is fixedly connected to the rear side of the upper plane of the base 101. A second piston shaft 202 is slidably connected inside the second fixed cylinder 201. The second fixed cylinder 201 and the second piston shaft 202 cooperate to form a sealed cavity. First flexible pipes 203 are fixedly connected between two adjacent first fixed cylinders 106 and between the second fixed cylinder 201 and the bottom first fixed cylinder 106. The length of the first flexible pipe 203 between two adjacent first fixed cylinders 106 has a margin, which is used to adapt to the position change between two adjacent first fixed cylinders 106 and the position change between the second fixed cylinder 201 and the bottom first fixed cylinder 106. The sealed cavity formed by the cooperation of the second fixed cylinder 201 and the second piston shaft 202 is communicated with the sealed cavity formed by the cooperation of the first fixed cylinder 106 and the adjacent first piston shaft 107 through the first flexible pipe 203, which is used to make the gas push the first piston shaft 107 to fit with the sloping soil layer. A limiting component for stabilizing the position of the second piston shaft 202 is arranged at the top of the second fixed cylinder 201.

[0033] As Figure 5 As shown in the figure, the limiting component includes a clamping shaft 204. The clamping shaft 204 is a wedge-shaped block, and its inclined surface faces upward. The clamping shaft 204 is slidably connected to the top of the second fixed cylinder 201. A linear array of limiting holes 205 is arranged on the left side of the second piston shaft 202. The linear array of limiting holes 205 is all in limiting cooperation with the clamping shaft 204. The internal contour of the limiting holes 205 is consistent with the contour of the clamping shaft 204 near the inclined surface. A second elastic element 206 is arranged between the clamping shaft 204 and the second fixed cylinder 201. The second elastic element 206 is a tension spring. The second elastic element 206 is used to drive the clamping shaft 204 to reset, lock the second piston shaft 202 and the second fixed cylinder 201 with each other, and stabilize the angle presented by the first hinge plate 109 and the second hinge plate 110, which is convenient for subsequent staff to measure.

[0034] As Figure 3 andFigure 6 As shown, the measuring assembly includes a sliding frame 301. The sliding frame 301 is slidably connected to the left side of the fitting frame 102. A fixed pushing frame 302 is slidably connected to the middle of the sliding frame 301. A dashboard 303 is installed on the fixed pushing frame 302 (the dashboard 303 has a leveling function to avoid the change of its value due to swinging following the fitting frame 102). A measuring frame 304 is rotatably connected to the fixed pushing frame 302. The linearly arrayed first hinge plates 109 and the linearly arrayed second hinge plates 110 are both in contact and cooperation with the measuring frame 304. The measuring frame 304 is externally fitted to the first hinge plates 109 and the second hinge plates 110, so that the measuring frame 304 rotates along the fixed pushing frame 302. The measuring frame 304 is fixedly connected to a first gear 305. A second rack frame 306 is slidably connected to the sliding frame 301. A second gear 307 is rotatably connected to the fixed pushing frame 302. Both the first gear 305 and the second gear 307 are meshed with the second rack frame 306. The second gear 307 is fixedly connected to a reading rod. The measuring frame 304 drives the reading rod to rotate around the dashboard 303 through the first gear 305, the second rack frame 306 and the second gear 307.

[0035] When it is necessary to measure the slope of the land, the staff places this device on the measured slope, makes the base 101 in a horizontal state, and the bottom of the fitting frame 102 contacts the slope. At this time, the staff rotates the rotating shaft 104. The rotation of the rotating shaft 104 drives the second steering gear 105 to rotate. The second steering gear 105 drives the first steering gear 103 to rotate. The first steering gear 103 drives the fitting frame 102 to deflect outward along the base 101. The fitting frame 102 drives the linearly arrayed first fixed cylinders 106 thereon to move synchronously. In this way, until the fitting frame 102 fits the slope. At this time, the central axis of the first fixed cylinder 106 is perpendicular to the slope. At this time, the staff pushes the first rack frame 111. The first rack frame 111 slides along the fitting frame 102. The first rack frame 111 drives the linearly arrayed leveling gears 112 to rotate. The leveling gears 112 drive the adjacent first fixed cylinders 106 to rotate along the fitting frame 102, and rotate the central axis of the first fixed cylinder 106 to the horizontal state. Then the staff rotates the limiting shaft 113. The limiting shaft 113 moves inward along the fitting frame 102 until the limiting shaft 113 contacts the first rack frame 111 and presses and fixes it. Then stop rotating the limiting shaft 113. At this time, the preparatory work for measuring the slope of the slope is completed.

[0036] When the preparation work for slope measurement is completed, at this time, the staff pushes the second piston shaft 202 to slide inward along the second fixed cylinder 201. The second piston shaft 202 pushes the air in the second fixed cylinder 201 into the sealed cavity where the bottom first fixed cylinder 106 cooperates with the adjacent first piston shaft 107 along the first flexible tube 203, and sequentially enters the sealed cavities where the remaining first fixed cylinders 106 cooperate with the adjacent first piston shafts 107 upward through the first flexible tube 203. At this time, the gas pressure in the sealed cavity where the first fixed cylinder 106 cooperates with the adjacent first piston shaft 107 increases, and the gas pushes the adjacent first piston shaft 107 to slide along the first fixed cylinder 106. At the same time, the first elastic element 108 is compressed until the staff observes that all the first piston shafts 107 are in contact with the ground. At this time, the pushing of the second piston shaft 202 is stopped. At the same time, the first piston shaft 107 drives the first hinge plate 109 and the second hinge plate 110 on it to move synchronously. To conform to the position change between two adjacent first piston shafts 107, both the first hinge plate 109 and the second hinge plate 110 rotate along the adjacent first piston shaft 107. At the same time, sliding occurs between the adjacent first hinge plate 109 and the second hinge plate 110 until the first piston shaft 107 is in contact with the ground. At this time, the first hinge plate 109 and the second hinge plate 110 between two adjacent first piston shafts 107 form a certain angle with the horizontal line. This angle is the slope of the slope between the two first piston shafts 107. By dividing the measured area of the slope into several small areas and presenting the slopes of the several small areas through the first hinge plate 109 and the second hinge plate 110, it is avoided that due to the unevenness of the slope, the error increases during large-scale unified measurement, and the measurement accuracy of the slope gradient is reduced.

[0037] When the second piston shaft 202 pushes the second fixed cylinder 201 to slide inward, the second piston shaft 202 drives the linear array of limit holes 205 on it to move synchronously. At this time, the limit holes 205 squeeze the clamping shaft 204, and the clamping shaft 204 slides along the second fixed cylinder 201 under the extrusion force. At the same time, the second elastic element 206 is stretched. In this way, until all the first piston shafts 107 in the linear array are in contact with the slope. At this time, the pushing of the second piston shaft 202 is stopped. Then the second elastic element 206 resets and drives the clamping shaft 204 to reset synchronously, so that the clamping shaft 204 is stuck into the adjacent limit hole 205 to limit the second piston shaft 202. By locking the second piston shaft 202 and the second fixed cylinder 201 with each other, the angle presented by the first hinge plate 109 and the second hinge plate 110 is stabilized, which is convenient for subsequent staff to measure.

[0038] After the staff stops pushing the second piston shaft 202, the staff controls the sliding frame 301 to slide along the fitting frame 102 to between the two first piston shafts 107, and then pushes the fixed push frame 302. The fixed push frame 302 drives the measuring frame 304 to contact and fit with the adjacent first hinge plate 109 and the adjacent second hinge plate 110. At this time, the measuring frame 304 deflects along the fixed push frame 302. At this time, the measuring frame 304 drives the first gear 305 thereon to rotate synchronously, and drives the second gear 307 to rotate through the second rack frame 306. The second gear 307 drives the reading rod thereon to rotate around the instrument panel 303. After the reading rod stops rotating, the staff records the value at this time, and then drives the fixed push frame 302 to reset, and tests the angles presented by the remaining first hinge plates 109 and the adjacent second hinge plates 110 in this way. Then the staff takes out the mode in the values and takes its average value to obtain the final degree.

[0039] After the measurement is completed, the staff pulls the clamping shaft 204. At this time, the second elastic element 206 is stretched, and the limit of the clamping shaft 204 on the second piston shaft 202 is released. Then the second piston shaft 202 is pulled to reset. At the same time, the first elastic element 108 resets and pushes the adjacent first piston shaft 107 to reset synchronously. In this way, until all the first piston shafts 107 in the linear array are reset to the initial state. Then the rotating shaft 104 is reset to rotate, so that the rotating shaft 104 drives the fitting frame 102 to reset to the initial state through the first steering gear 103 and the second steering gear 105. Then the limiting shaft 113 is rotated to release the extrusion of the first rack frame 111, and drives the first rack frame 111 to reset and slide to the initial state. Then wait for the next detection of the slope gradient and repeat the above steps.

[0040] Embodiment 2: On the basis of Embodiment 1, as Figure 2 shown, it further includes a fixing component for stabilizing the base 101. The fixing component is arranged on the base 101. The fixing component includes a rotating shaft 401. The rotating shaft 401 is rotatably connected to the base 101. Two auger shafts 402 distributed in mirror image are rotatably connected to the bottom of the base 101. The bottom of the rotating shaft 401 is fixedly connected with a first sprocket 403. The bottoms of the two auger shafts 402 distributed in mirror image are both fixedly connected with a second sprocket 404. A chain is wound around the first sprocket 403 and the two second sprockets 404 distributed in mirror image. The radius of the first sprocket 403 is larger than the radius of the second sprocket 404 to ensure that the chain meshes with the first sprocket 403, and the two auger shafts 402 distributed in mirror image are inserted into the soil layer to fix the base 101, so as to avoid shaking during the subsequent slope measurement, resulting in an increase in the error of the slope gradient.

[0041] After the staff member makes the bottom of the fitting frame 102 contact with the slope, the staff member rotates the rotating shaft 401. The rotating shaft 401 drives the first sprocket 403 at its bottom to rotate. The first sprocket 403 drives two second sprockets 404 distributed in mirror image to rotate synchronously through a chain. The second sprockets 404 drive the adjacent auger shafts 402 to rotate respectively. The auger shafts 402 rotate and contact the ground, and gradually penetrate into the soil layer. At this time, the base 101 deflects gradually downward along the fitting frame 102 until the base 101 is in a horizontal state. Then, stop rotating the rotating shaft 401, and fix the base 101 by penetrating the soil layer with the two auger shafts 402 distributed in mirror image, so as to avoid shaking during the subsequent slope measurement, resulting in an increase in the error of the slope of the slope.

[0042] Embodiment 3: On the basis of Embodiment 2, as Figure 7 shown, it further includes a cleaning component for cleaning sundries at the measurement position. The cleaning component is arranged on the base 101. The cleaning component includes a third fixed cylinder 501. The third fixed cylinder 501 is fixedly connected to the front side of the upper plane of the base 101. A third piston shaft 502 is slidably connected inside the third fixed cylinder 501. The third fixed cylinder 501 and the third piston shaft 502 cooperate to form a sealed cavity. An air outlet shell 503 is fixedly connected to the right side of the fitting frame 102. The fitting frame 102 and the air outlet shell 503 cooperate to form a sealed cavity. A second flexible pipe 504 is arranged between the third fixed cylinder 501 and the air outlet shell 503. The length of the second flexible pipe 504 has a surplus to adapt to the position change of the fitting frame 102. The sealed cavity formed by the cooperation of the third fixed cylinder 501 and the third piston shaft 502 is communicated with the sealed cavity formed by the cooperation of the fitting frame 102 and the air outlet shell 503 through the second flexible pipe 504. The third piston shaft 502 pushes the gas in this sealed cavity into the second flexible pipe 504, so that the air in the sealed cavity formed by the cooperation of the third fixed cylinder 501 and the third piston shaft 502 enters the sealed cavity formed by the cooperation of the fitting frame 102 and the air outlet shell 503. Linear arrays of air outlet holes 505 are arranged on the front and rear sides inside the air outlet shell 503. The linear arrays of air outlet holes 505 on the front and rear sides inside the air outlet shell 503 are alternately distributed to avoid gas counterflow, resulting in stones being unable to leave the measurement position. The third piston shaft 502 is provided with a reset component for changing the air intake position. By impacting small stones and fallen leaves on the slope, the small stones and fallen leaves are forced by the impact force to move away from the soil layer at the measurement position, avoiding the first piston shaft 107 contacting the soil layer and being blocked by stones, and reducing the subsequent slope measurement accuracy.

[0043] As Figure 8As shown, the reset component includes an inner shaft 506. The inner shaft 506 is rotatably connected to the inside of the third piston shaft 502. The third piston shaft 502 is provided with three air extraction holes 507 arranged in an annular array. The air extraction holes 507 are fan-shaped holes. The bottom of the inner shaft 506 is fixedly connected with three blocking blocks 508 arranged in an annular array. The three blocking blocks 508 arranged in an annular array are all in sealing cooperation with the three air extraction holes 507 arranged in an annular array. The inner shaft 506 drives the three blocking blocks 508 to rotate, releasing or opening the blocking of the air extraction holes 507 by the blocking blocks 508. When resetting the third piston shaft 502, it is used to allow the outside air to enter the third fixed cylinder 501 along the three air extraction holes 507 arranged in an annular array, avoiding the gas entering the third fixed cylinder 501 from the air outlet hole 505. The gas drives the stones and fallen leaves to move to the measurement position again under the extraction force.

[0044] When the staff drives the fitting frame 102 to fit with the slope, the staff pushes the third piston shaft 502 to slide along the third fixed cylinder 501. At this time, the third piston shaft 502 pushes the air in the third fixed cylinder 501 to enter the sealed cavity where the air outlet housing 503 cooperates with the fitting frame 102 along the second flexible tube 504, and is discharged from the air outlet holes 505 arranged in a linear array on the front and back sides in the air outlet housing 503. The discharged gas impacts the small stones and fallen leaves on the slope, causing the small stones and fallen leaves to move away from the soil layer at the measurement position under the impact force, avoiding direct contact with the stones when the first piston shaft 107 contacts the soil layer, and reducing the subsequent slope measurement accuracy. In this way, until the third piston shaft 502 slides to the bottom along the third fixed cylinder 501.

[0045] After the third piston shaft 502 slides to the bottom along the third fixed cylinder 501, at this time, the staff rotates the inner shaft 506. The rotation of the inner shaft 506 drives the three blocking blocks 508 arranged in an annular array to rotate synchronously. The rotation of the three blocking blocks 508 arranged in an annular array releases the blocking of the three air extraction holes 507 arranged in an annular array. Then the staff pulls the third piston shaft 502 to reset, allowing the outside air to directly enter the third fixed cylinder 501 along the three air extraction holes 507 arranged in an annular array, avoiding the gas entering the third fixed cylinder 501 from the air outlet hole 505. The gas drives the stones and fallen leaves to move to the measurement position again under the extraction force. Then, after the third piston shaft 502 slides to the top along the third fixed cylinder 501, the inner shaft 506 is rotated again, so that the inner shaft 506 drives the three blocking blocks 508 arranged in an annular array to block the three air extraction holes 507 arranged in an annular array. Then the third piston shaft 502 is pushed to slide towards the bottom of the third fixed cylinder 501 again. This cycle continues until the stones and fallen leaves at the measurement position are cleaned up. Then the inner shaft 506 is reset to the initial position, and the measurement of the slope of the slope begins.
