Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping devices, and in particular to a surveying and mapping device for natural resource investigation and collection. Background Art

[0002] In the survey and collection of natural resources, surveying and mapping devices are key tools for obtaining geographic spatial information and accurately mapping resource distribution. When surveying and mapping devices are used in field environments, the geological conditions in the field are complex and diverse, among which soft soil is an extremely common condition. In such soft soil areas, after the bracket of the surveying and mapping device is directly placed, the legs of the bracket are very easy to sink because the soil is difficult to provide sufficiently solid support. The soil in different locations has different degrees of sinking due to differences in composition, humidity, compaction degree and other factors. Moreover, in actual use, various external forces, such as collisions with passing animals and vibrations caused by wind, will further aggravate the sinking of the legs. When the sinking degree of each leg is inconsistent, the bracket will deflect, which will cause deviations in the measurement angle, and ultimately seriously affect the measurement accuracy.

[0003] In the prior art, for example, a Chinese invention patent with authorization announcement number CN114754748B discloses a geographic surveying and mapping instrument, a surveying and mapping method and an application. In the public document, an anti-sinking airbag is set so that when the geographic surveying and mapping instrument is used for geographic surveying and mapping on soft ground, after the legs of the geographic surveying and mapping instrument are inserted into the ground, the anti-sinking airbag is controlled to expand and become larger, so that the anti-sinking airbag is in direct contact with the ground, thereby increasing the direct contact area between the legs of the geographic surveying and mapping instrument and the ground, thereby preventing the legs from sinking into the soil. However, in the public document, the same size of anti-sinking airbags are set on the end face of each leg. When the hardness of the ground on which different legs are located is different, there may still be a situation where the sinking degree of different legs is inconsistent, which leads to deviation in the measurement angle and affects the measurement accuracy.

However, at this time, there may be a difference between the axial direction of the positioning plate and the surveying and mapping reference point. At this time, the adjustment part adjusts the position of the total station on the mounting frame while keeping the center of gravity of the positioning plate unchanged, thereby ensuring that the vertical line where the total station is located is on the surveying and mapping reference point, further improving the accuracy of surveying and mapping.

[0024] like Figures 1 to 8 As shown, an embodiment of the present invention provides a surveying and mapping device for natural resource survey and collection, which includes a positioning plate 110, a mounting frame, a positioning pin 140 and an adjusting member.

[0025] The positioning disk 110 has an upper end surface and a lower end surface. The lower end surface of the positioning disk 110 is provided with a plurality of legs 120. The plurality of legs 120 are evenly distributed along the circumferential direction of the positioning disk 110. Each leg 120 is hinged to the positioning disk 110, and each leg 120 can be telescopic. A first locking piece is provided on each leg 120. The first locking piece is used to limit the length change of the leg 120. Specifically, the first locking piece is a first locking knob 121. The leg 120 includes a fixed portion and a sliding portion. The fixed portion is hollow inside, and one end of the sliding portion is inserted into the fixed portion. The first locking knob 121 is spirally connected to the fixed portion. The first locking knob 121 can abut the sliding portion. The first locking knob 121 can squeeze the sliding portion so that the sliding portion cannot slide on the fixed portion, thereby limiting the length change of the leg 120.

[0026] The mounting frame includes a base plate 130 and a joint 131. The base plate 130 is used to connect the positioning plate 110. The joint 131 is fixedly connected to the base plate 130. The total station can be installed on the joint 131. Before surveying and mapping begins, the total station is placed in a suitcase. When surveying and mapping is required, the total station is installed on the joint 131 to prevent damage to the total station by staff during transportation.

[0027] There are multiple positioning pins 140, each positioning pin 140 is coaxially fixedly connected to the lower end of a leg 120, and the lower end of each positioning pin 140 is set to a pointed end to ensure that the positioning pin 140 can be smoothly inserted into the ground. There are multiple limiting claws 150 on the positioning pin 140, and the multiple limiting claws 150 are evenly distributed around the circumferential direction of the positioning pin 140. Specifically, each limiting claw 150 includes a first claw body 151 and a second claw body 152, one end of the first claw body 151 is hinged to the side wall of the positioning pin 140, and the other end of the first claw body 151 is hinged to one end of the second claw body 152; a sliding sleeve 160 is coaxially slidably provided on the positioning pin 140, and the sliding sleeve 160 can slide on the outer side wall of the positioning pin 140 along the axial direction of the positioning pin 140. In the initial state, the sliding sleeve 160 is at the upper end of the positioning pin 140. The end of the second claw body 152 away from the first claw body 151 is rotatably connected to the sliding sleeve 160. When the sliding sleeve 160 slides along the axial direction of the positioning needle 140, the angle between the first claw body 151 and the second claw body 152 can change. In the initial state, according to the position of the sliding sleeve 160 on the positioning needle 140, the angle between the first claw body 151 and the second claw body 152 is at the minimum state. As the angle between the first claw body 151 and the second claw body 152 increases, it becomes more difficult for the positioning needle 140 to penetrate into the ground.

[0028] The adjusting member can adjust the sliding distance of the sliding sleeve 160 on the positioning pin 140 to be larger when the difficulty of the positioning pin 140 penetrating the ground is lower. On the contrary, when the difficulty of the positioning pin 140 penetrating the ground is higher, the adjusting member adjusts the sliding distance of the sliding sleeve 160 on the positioning pin 140 to be smaller, thereby ensuring that the difficulty of multiple positioning pins 140 penetrating the ground remains at the same state. After the total station is installed on the joint 131, irregular settlement of multiple legs 120 is prevented, thereby reducing measurement errors and further improving the accuracy of surveying and mapping.

[0029] Furthermore, if there are differences in ground height, when multiple legs 120 of the same length are inserted into the ground, the positioning plate 110 is in a non-horizontal state. First, keep the positions of different legs 120 contacting the ground unchanged, adjust the lengths of different legs 120, and ensure that the positioning plate 110 is in a horizontal state. At this time, the axial direction of the positioning plate 110 is different from the surveying and mapping reference point. The adjustment part can maintain the center of gravity of the positioning plate 110 unchanged, and adjust the position of the total station on the mounting frame, so that the vertical line where the total station is located is directly above the surveying and mapping reference point, further improving the accuracy of surveying and mapping.

[0030] The surveying and mapping device for natural resource survey and collection of the present invention adjusts the lengths of the plurality of legs 120 to the same state when surveying and mapping in the field, and then uses the first locking member to limit the length change of the legs 120. Then, the plurality of legs 120 are unfolded, and the lower ends of the plurality of legs 120 are inserted into the ground. Since the soil conditions of each leg 120 may be different, during the process of inserting the lower end of the leg 120 into the ground, the positioning pin 140 directly contacts the soil. When the positioning pin 140 is inserted into the soil, the adjustment member adjusts the sliding sleeve 140 to adjust the length of the plurality of legs 120. 60 The more the positioning pin 140 slides downward, in the initial state, the sliding sleeve 160 is on the upper part of the positioning pin 140. When the sliding sleeve 160 approaches the lower end of the positioning pin 140, the sliding sleeve 160 squeezes the first claw body 151 and the second claw body 152, so that the angle between the first claw body 151 and the second claw body 152 increases, thereby increasing the resistance of the positioning pin 140 entering the soil, reducing the different degrees of settlement of different legs 120 during use, thereby reducing the measurement error and improving the accuracy of surveying and mapping.

[0031] In one embodiment, the adjusting member includes a reference plate 170 and a first driving source. The reference plate 170 is coaxially fixed on the surveying and mapping reference point. Specifically, since the surveying and mapping reference point is clear, the reference plate 170 is fixed on the ground to ensure that the reference plate 170 is coaxial with the surveying and mapping reference point. A plurality of winding rollers are rotatably arranged on the reference disk 170, and a first driving source is arranged on the reference disk 170. The first driving source can drive the plurality of winding rollers to rotate simultaneously, and the first driving source drives each winding roller with the same rotational force, and each winding roller is connected to a sliding sleeve 160 by a traction rope 210, and the length of each traction rope 210 is the same. During the process of inserting the positioning needle 140 into the ground, the first driving source always exerts a winding force on the traction rope 210, so that the sliding sleeve 160 slides downward on the positioning needle 140. The sliding distance of the sliding sleeve 160 on the positioning needle 140 can be determined according to the amount of traction rope 210 wound on the winding roller, and the amount of traction rope 210 wound on the plurality of winding rollers can be compared and analyzed, so as to determine the difficulty of different positioning needles 140 to penetrate into the ground.

[0032] In one embodiment, the positioning pin 140 is provided with a first slide groove and a second slide groove, the first slide groove and the second slide groove are parallel to the axis of the positioning pin 140, and the first slide groove and the second slide groove are arranged at intervals. The lower end of the first slide groove is connected with the lower end of the second slide groove through the first connecting groove. The traction rope 210 enters the second slide groove from the upper end of the second slide groove, and then the traction rope 210 slides along the second slide groove, the traction rope 210 passes through the first connecting groove and enters the lower end of the first slide groove, the traction rope 210 slides along the first slide groove, and the traction rope 210 is fixedly connected to the sliding sleeve 160 after the upper end of the first slide groove is separated from the first slide groove. Further, a smooth wheel is provided at the upper end of the second slide groove, the smooth wheel is rotatably connected to the positioning pin 140, and the traction rope 210 enters the second slide groove after being wound around the smooth wheel, ensuring that the traction rope 210 can smoothly enter the second slide groove, while reducing the wear of the traction rope 210 at the upper end of the second slide groove. In addition, by providing the first sliding groove, the second sliding groove and the first connecting groove, it is ensured that when the positioning pin 140 is inserted into the ground, the sliding sleeve 160 can slide downward smoothly on the positioning pin 140.

[0033] In one embodiment, the adjusting member further comprises a rotating disk 250, an installation box 260 and a second driving source. The rotating disk 250 is coaxially rotatably connected to the reference disk 170, the rotating disk 250 is located on the upper end surface of the reference disk 170, and a guide rail along its own radial direction is provided on the rotating disk 250. The installation box 260 is rotatably provided on the rotating disk 250, and the installation box 260 can slide along the guide rail, and multiple winding rollers and the first driving source are installed inside the installation box 260. In this embodiment, the installation box 260 is set to a transparent material, so that the staff can observe the multiple winding rollers inside the installation box 260. The second driving source is used to drive the rotating disk 250 to rotate on the reference disk 170. The second driving source can also drive the installation box 260 to slide along the guide rail. Specifically, when the second driving source drives the rotating disk 250 to rotate on the reference disk 170, under the action of multiple winding rollers and the traction rope 210, since the traction rope 210 is in a tensioned state, the installation box 260 and the rotating disk 250 rotate relative to each other. At this time, only the direction of the guide rail is changed. Furthermore, the direction of the guide rail is determined by the difficulty of different positioning pins 140 to penetrate into the ground. The direction of the guide rail is away from the positioning pin 140 that is easiest to penetrate into the ground. When the second driving source drives the installation box 260 to slide along the guide rail, the multiple winding rollers on the installation box 260 move synchronously along the guide rail. By clarifying the direction of the guide rail, after the installation box 260 slides along the guide rail, the sliding sleeve 160 connected to the positioning needle 140 that is easiest to penetrate into the ground further slides downward along the axial direction of the positioning needle 140, further increasing the angle between the first claw body 151 and the second claw body 152, thereby balancing the difficulty of different positioning needles 140 penetrating into the ground.

[0034] In one embodiment, the second driving source includes a gear ring 270 and a first knob 280. The first knob 280 is rotatably connected to the reference disk 170. A first gear is fixedly provided on the first knob 280. The gear ring 270 is coaxially fixedly connected to the outer peripheral wall of the rotating disk 250. The gear ring 270 is always engaged with the first gear. When it is necessary to drive the rotating disk 250 to rotate, the staff can do so by rotating the first knob 280.

[0035] In one embodiment, the second driving source further includes a second knob 290 and a lead screw 310, the lead screw 310 is rotatably arranged in the guide rail, the second knob 290 is rotatably connected to the rotating disk 250, the second knob 290 is arranged vertically, a first bevel gear is fixedly arranged at the end of the lead screw 310, a second bevel gear is fixedly arranged at the lower end of the second knob 290, the first bevel gear and the second bevel gear are always meshed, and when the second knob 290 is rotated, the lead screw 310 rotates in the guide rail. A rotating block is rotatably arranged on the installation box 260, the rotating block is spirally connected to the lead screw 310, and the rotating block is slidably arranged along the guide rail. Under the action of multiple winding rollers and the traction rope 210, since the traction rope 210 is in a tensioned state, and under the action of the rotating block, when the rotating disk 250 rotates on the reference disk 170, the installation box 260 is in a stationary state, thereby preventing the traction rope 210 from being entangled on the installation box 260.

[0036] In one embodiment, the adjusting member further comprises a mounting plate 320, a counterweight plate 330, an adjusting plate 340 and a transmission member, wherein the mounting plate 320 is coaxially rotatably connected to the upper end surface of the positioning plate 110. The counterweight plate 330 is slidably connected to the mounting plate 320, specifically, a limiting protrusion 321 is provided on the mounting plate 320, a limiting groove 331 is provided on the counterweight plate 330, and the limiting protrusion 321 is slidably provided in the limiting groove 331, so that the counterweight plate 330 and the mounting plate 320 can slide relative to each other, and further, a counterweight block is provided on the counterweight plate 330, and in the initial state, the counterweight plate 330 and the mounting plate 320 are in a coaxial state. The adjusting disk 340 is rotatably connected to the mounting frame, specifically, the adjusting disk 340 is rotatably connected to the base plate 130. In the initial state, the adjusting disk 340 and the base plate 130 are in a coaxial state, and the adjusting disk 340 and the counterweight plate 330 are in a coaxial state. The adjusting disk 340 and the counterweight plate 330 are slidably connected, and the adjusting disk 340 and the counterweight plate 330 can slide relative to each other, and the direction of relative sliding between the adjusting disk 340 and the counterweight plate 330 is opposite to the direction of relative sliding between the counterweight plate 330 and the mounting disk 320. The transmission member is arranged between the adjustment disk 340 and the counterweight disk 330. When there is a difference in ground height, when multiple legs 120 of the same length are inserted into the ground, the positioning disk 110 is in a non-horizontal state. First, the positions of different legs 120 contacting the ground are kept unchanged, and the lengths of different legs 120 are adjusted to ensure that the positioning disk 110 is in a horizontal state, resulting in a difference between the axial direction of the positioning disk 110 and the surveying and mapping reference point. At this time, when the total station is installed on the joint 131, the actual measurement reference point of the total station is offset from the surveying and mapping reference point. The staff needs to push the adjustment disk 340 to get close to the vertical line where the surveying and mapping reference point is located. If the adjustment disk 340 can be pushed, there is no It is necessary to rotate the adjusting disk 340. If the adjusting disk 340 cannot be pushed, the adjusting disk 340 needs to be rotated so that the direction in which the adjusting disk 340 approaches the vertical line where the surveying and mapping reference point is located is parallel to the direction in which the adjusting disk 340 and the counterweight disk 330 slide relative to each other, thereby ensuring that the staff can smoothly push the adjusting disk 340. When the staff pushes the adjusting disk 340 to move relative to the counterweight disk 330, the counterweight disk 330 moves relative to the mounting disk 320 at the same time through the transmission of the transmission member, and the axis of the counterweight block and the axis of the adjusting disk 340 move away from each other, thereby ensuring that the overall center of gravity of the positioning disk 110 remains unchanged, thereby achieving adjustment of the actual measurement reference point of the total station.

[0037] In one embodiment, the transmission member includes a first rack 350, a second rack 360 and a transmission roller 370, the first rack 350 is fixedly connected to the adjustment disk 340, the second rack 360 is fixedly connected to the counterweight disk 330, the first rack 350 and the second rack 360 are arranged in parallel, and the first rack 350 and the second rack 360 are both parallel to the limiting groove 331. Further, the limiting protrusion 321 penetrates the limiting groove 331, one end of the transmission roller 370 is rotatably connected to the limiting protrusion 321, and a fixed gear is arranged on the transmission roller 370, and the fixed gear meshes with the first rack 350 and the second rack 360 at the same time. When the staff pushes the adjustment disk 340 to move relative to the counterweight disk 330, the counterweight disk 330 moves relative to the mounting disk 320 at the same time, and the axis of the counterweight block and the axis of the adjustment disk 340 are away from each other.

[0038] In one embodiment, a positioning rod 410 is coaxially arranged on the mounting frame. Specifically, the positioning rod 410 is coaxially connected to the base plate 130. The positioning rod 410 can be telescopically arranged.
