Description

Technical Field

[0001] This invention relates to the field of survey point marking technology, specifically to a geological disaster prevention and control surveying and mapping device and method. Background Technology

[0002] Surveying and mapping equipment typically includes a marking device. The marking device is a fundamental tool or equipment used in surveying and mapping work to mark, locate, and measure key points, providing benchmarks or control points for subsequent measurement, monitoring, and data analysis.

[0003] Referring to Chinese Patent Publication No. CN115014308B, a device for marking and measuring points in marine engineering relates to the field of marking and measuring points. It includes a fixed shell, which is a rectangular shell structure with an installation space inside. A support seat is slidably disposed inside the installation space of the fixed shell. A collection shell is fixedly disposed on top of the support seat. With the cooperation of the collection shell and the support seat, when the device encounters heavy rain or other weather conditions, the support seat retracts into the fixed shell, thus protecting other components of the device in sequence, thereby extending the service life of the device and enabling the device to automatically provide protection in windy and rainy weather.

[0004] During geological disaster prevention and exploration, staff need to set up portable landmarks. Under the influence of soft ground subsidence or wind, the landmarks may shift. During the installation process, the metal nails at the bottom of the landmark are usually inserted directly into the ground, making it difficult to ensure that the landmark is installed vertically. If the insertion rod is tilted, it will cause the center point to deviate from the actual ground point during image measurement. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a geological disaster prevention and control surveying and mapping device and method. The device is fixed to the ground by an adjusting screw. Under the action of the threads of the cylinder and the adjusting screw, the height of one corner of the plate is changed, making the plate and circular plate parallel to the ground. The spiral lifting component is perpendicular to the ground and completes drilling. The elastic action controls the opening and closing of the circular plate, facilitating the replacement of the spiral lifting component and the marker, accelerating the placement of the marker, and ensuring that the marker and the survey point are perpendicular to each other.

[0006] Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: A geological disaster prevention and control exploration and mapping device, comprising: a flat plate, each corner of which is provided with a corner groove, and each corner of which is provided with an adjusting screw, the adjusting screw passing through the interior of the flat plate and slidably connected to the interior of the flat plate, each corner groove being provided with a spiral lifting component, the spiral lifting component being threadedly connected to the adjusting screw, the spiral lifting component driving one corner of the flat plate to move vertically by rotation, the top of the flat plate having two sliding grooves, each sliding groove being connected to a first semicircular plate by a slider, one side of the slider being connected to the inner wall of the sliding groove by a spring, the first semicircular plate and the second semicircular plate abutting and forming a circular plate, the center of the circular plate having a first threaded groove, the side of the first threaded groove having several first corner holes equidistantly distributed along the circumference, the first threaded groove being threadedly connected to a drill rod, the separation and engagement of the first semicircular plate and the second semicircular plate being controlled by elastic action, and the first corner holes being slidably connected to the side plates.

[0007] Preferably, the plate is a polygon with no less than three sides, and several side plates are connected to the side of the pole. Each side plate has a cutting edge connected to its bottom. The side plate has a triangular cross-sectional view. The end of the side plate away from the pole axis is a pointed tip. The side plate is a thin plate. The distance from the cutting edge to the pole axis gradually decreases in the vertical direction. The bottom end of the cutting edge is a blade tip.

[0008] Preferably, the two grooves are symmetrically distributed along the axial direction of the flat plate. The grooves are slidably connected to the sliders. The top of each slider is connected to the first wing plate through a support plate. The side of several first wing plates that are close to each other is connected to the side of the first semicircular plate. The side of the second semicircular plate is connected to the second wing plate. The second wing plate is connected to the top of the flat plate through a support plate. A level is connected to the top of the second semicircular plate. A first insertion hole is opened through the top of one end of the first wing plate. A second insertion hole is opened through the top of the slider. A third insertion hole is opened through the top of the support plate. A fourth insertion hole is opened through the bottom of the groove. The axes of the first insertion hole, the second insertion hole, the third insertion hole, and the fourth insertion hole are located on the same straight line. The first insertion hole is inserted into the insertion rod.

[0009] Preferably, the slider moves along the groove direction. When the slider moves directly above the fourth insertion hole, the slider is in the first position. The first semicircular plate and the second semicircular plate abut against each other to form a circular plate. The bottom end of the insertion rod passes through the first insertion hole, the second insertion hole, and the third insertion hole in sequence and is inserted into the fourth insertion hole. When the slider moves the first semicircular plate away from the second semicircular plate, the slider is in the second position. A spiral lifting component is placed between the first semicircular plate and the second semicircular plate. The spiral lifting component is threadedly connected to the circular plate. A ring plate is provided directly below the circular plate. Several connecting plates are connected to the side of the ring plate. The several connecting plates are equidistantly distributed in the circumferential direction of the ring plate. One end of the connecting plate is connected to the inner wall of the flat plate. Several second corner holes are opened on the inner wall of the ring plate. The upper surface of the circular plate is parallel to the upper surface of the flat plate.

[0010] Preferably, the spiral lifting component includes: a first rod body, with a first drill bit connected to the bottom of the first rod body and a first threaded rod connected to the top of the first rod body, the first threaded rod being connected to a handle via a vertical rod; the adjusting screw includes: a second rod body, with a second threaded rod connected to the top of the second rod body and a second drill bit connected to the bottom of the second rod body.

[0011] Preferably, the corner groove is a triangular groove, which divides one corner of the flat plate into an upper plate and a lower plate. A first channel is formed through the top of the upper plate, and the bottom of the first channel is connected to the corner groove. A third channel is formed at the bottom of the lower plate, and a second channel is formed through the top of the third channel, which is connected to the corner groove. An upper pressure plate is provided directly below the first channel. The bottom of the upper pressure plate is connected to the lower pressure plate through a cylinder. A second threaded groove is formed on the inner wall of the cylinder. Several levers are connected to the side of the cylinder, and the levers are equidistantly distributed along the circumference of the cylinder. The upper pressure plate abuts against the upper plate, and the lower pressure plate abuts against the lower plate.

[0012] Preferably, the diameter of the third channel is greater than the diameter of the second channel, the diameter of the first channel is equal to the diameter of the second channel, the inner diameter of the upper plate is the same as the inner diameter of the lower plate, and the inner diameter of the upper plate is smaller than the diameter of the cylinder.

[0013] A method, applied to the geological disaster prevention and exploration mapping device, involves inserting an adjusting screw into the ground, fixing the adjusting screw to the exploration ground, placing a plate on the exploration ground, pushing the first semicircular plate, compressing the spring, and moving the slider from the first position to the second position, separating the first and second semicircular plates, and placing the bottom end of the spiral lifting component between the first and second semicircular plates. The first semicircular plate, under the thrust of the spring's recovery, abuts against the second semicircular plate to form a circular plate. The spiral lifting component is rotated to connect with the first threaded hole. The level is observed, and the offset direction of the plate is determined by the position of the bubble. The cylinder is threadedly connected to the adjusting screw. Rotating the cylinder causes it to move slowly vertically. The upper and lower pressure plates drive the flat plate, making it parallel to the ground. The circular plate is parallel to the flat plate, thus parallel to the ground. The plane of the circular plate is perpendicular to the axis of the auger lifting component. At this time, the auger lifting component is also perpendicular to the ground. Rotating the auger lifting component causes its tip to drill into the ground to a preset depth. The first threaded rod of the auger lifting component is located below the first threaded groove. The auger lifting component is slidably connected to the first threaded groove, pushing the first semicircular plate. The first semicircular plate separates from the second semicircular plate. The auger lifting component is removed, and the bottom end of the marker passes through the ring plate. The middle part of the marker is slidably connected to the first threaded groove. The marker is inserted into the hole opened in the ground. This reduces the adjustment time for the auxiliary marker insertion platform to be parallel to the ground, improves the accuracy of the marker's vertical insertion into the survey point, and facilitates the replacement of the marker and the auger lifting component.

[0014] Beneficial Effects: This invention provides a geological disaster prevention and control surveying and mapping device and method. Compared with the prior art, it has the following beneficial effects: 1. The entire device has a simple structure. The flat plate and the circular plate are parallel and fixed to the exploration ground by adjusting screws. Under the action of the threads of the cylinder and the adjusting screws, the height of one corner of the flat plate is changed, so that the flat plate and the circular plate are parallel to the ground. The screw lifting component is perpendicular to the ground and completes the drilling. The elastic effect is used to control the opening and closing of the circular plate, which facilitates the replacement of the screw lifting component and the marker, speeds up the placement of the marker, and ensures that the marker and the survey point are perpendicular to each other.

[0015] 2. To avoid contact between the soil and the first threaded hole during drilling, and to ensure the drilling depth, the height of the first rod and the first threaded rod must not be less than the drilling depth. Therefore, the circular plate needs to be at a certain height from the ground. Because there is a height difference between the circular plate and the ground, it is difficult to directly adjust the circular plate and make it level with the ground. Instead, the circular plate is fixedly connected to the flat plate, the circular plate and the flat plate are set parallel to each other, and the circular plate and the flat plate move synchronously. The tilt angle of the circular plate is adjusted by finely adjusting the tilt angle of the flat plate.

[0016] 3. The distance from the side plate to the axis of the marker is slightly larger than the diameter of the borehole. The side plate is a thin plate with a pointed tip on the outside. The distance from the cutting edge to the axis of the marker gradually decreases in the vertical direction. The bottom of the cutting edge is the tip. The cutting edge facilitates the side plate to break through the soil surface. Finally, the marker and the cutting edge move to the bottom of the borehole. Through the contact between the side plate and the ground, the marker is less likely to rotate due to wind or external environment, reducing the possibility of the marker shifting.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1 - Figure 14As shown, an embodiment of the present invention provides a geological disaster prevention and control surveying and mapping device, comprising: a flat plate 61, each corner of the flat plate 61 having a corner groove 62, each corner of the flat plate 61 having an adjusting screw, the adjusting screw passing through the interior of the flat plate 61 and slidably connected to the interior of the flat plate 61, each corner groove 62 having a spiral lifting component, the spiral lifting component being threadedly connected to the adjusting screw, the spiral lifting component rotating to drive one corner of the flat plate 61 to move vertically, and the top of the flat plate 61 having two sliding grooves 38, each... The slide grooves 38 are all connected to the first semicircular plate 31 via sliders 35. One side of the slider 35 is connected to the inner wall of the slide groove 38 via spring 37. The first semicircular plate 31 and the second semicircular plate 41 abut against each other to form a circular plate. A first threaded groove 43 is provided at the center of the circular plate. Several first corner holes 45 are provided on the side of the first threaded groove 43, which are equidistantly distributed along the circumference. The first threaded groove 43 is threadedly connected to the drill rod. The separation and engagement of the first semicircular plate 31 and the second semicircular plate 41 are controlled by elastic action. The first corner holes 45 are slidably connected to the side plate 12.

[0037] One or two slide grooves 38 can be formed on the plate 61. Each slide groove 38 is connected to a slider 35, a support plate 34, and a first wing plate 32. Reducing the number of slide grooves 38 can reduce costs and the weight of the entire device. By setting two slide grooves 38, the sides of both ends of the first semicircular plate 31 are connected to the first wing plate 32, increasing the support points of the first semicircular plate 31. The two slide grooves 38 extend to intersect at one corner of the plate 61, moving the first semicircular plate 31 towards that corner.

[0038] The plate 61 is a polygon with no less than three sides. Several side pieces 12 are connected to the side of the rod 11. Each side piece 12 has a blade 13 connected to its bottom. The side piece 12 has a triangular cross-sectional view. The end of the side piece 12 away from the axis of the rod 11 is a pointed end.

[0039] Two sliding grooves 38 are symmetrically distributed along the axis of the plate 61. The sliding grooves 38 are slidably connected to the sliders 35. The top of each slider 35 is connected to the first wing plate 32 through a support plate 34. Several first wing plates 32 are connected to the side of the first semicircular plate 31 on the side of their adjacent sides. The side of the second semicircular plate 41 is connected to the second wing plate 42. The second wing plate 42 is connected to the top of the plate 61 through a support plate 34. A level 44 is connected to the top of the second semicircular plate 41. A first insertion hole 33 is opened through the top of one end of the first wing plate 32. A second insertion hole 36 is opened through the top of the slider 35. A third insertion hole 51 is opened through the top of the support plate 34. A fourth insertion hole 52 is opened through the bottom of the sliding groove 38. The axes of the first insertion hole 33, the second insertion hole 36, the third insertion hole 51, and the fourth insertion hole 52 are on the same straight line. The first insertion hole 33 is inserted into the insertion rod 39.

[0040] The slider 35 moves along the direction of the slide groove 38. When the slider 35 moves directly above the fourth insertion hole 52, the slider 35 is in the first position. The first semicircular plate 31 and the second semicircular plate 41 abut against each other and form a circular plate. The bottom end of the insertion rod 39 passes through the first insertion hole 33, the second insertion hole 36, and the third insertion hole 51 in sequence and is inserted into the fourth insertion hole 52. When the slider 35 drives the first semicircular plate 31 away from the second semicircular plate 41, the slider 35 is in the second position. The first semicircular plate 31 and the second semicircular plate 41 are used to pick up and put in the spiral lifting component. The spiral lifting component is threadedly connected to the circular plate. A ring plate 46 is provided directly below the circular plate. Several connecting plates 48 are connected to the side of the ring plate 46. The several connecting plates 48 are equidistantly distributed in the circumferential direction of the ring plate 46. One end of the connecting plate 48 is connected to the inner wall of the flat plate 61. Several second corner holes 47 are opened on the inner wall of the ring plate 46. The upper surface of the circular plate is parallel to the upper surface of the flat plate 61.

[0041] The spiral lifting component includes: a first rod body 21, a first drill bit 22 connected to the bottom of the first rod body 21, a first threaded rod 23 connected to the top of the first rod body 21, and a handle 24 connected to the first threaded rod 23 via a vertical rod. The adjusting screw includes: a second rod body 71, a second threaded rod 72 connected to the top of the second rod body 71, and a second drill bit 73 connected to the bottom of the second rod body 71.

[0042] The corner groove 62 is a triangular groove that divides one corner of the flat plate 61 into an upper plate and a lower plate. The top of the upper plate has a first channel 63 that runs through it, and the bottom of the first channel 63 is connected to the corner groove 62. The bottom of the lower plate has a third channel 65, and the top of the third channel 65 has a second channel 64 that runs through it, and the top of the second channel 64 is connected to the corner groove 62. An upper pressure plate 76 is provided directly below the first channel 63. The bottom of the upper pressure plate 76 is connected to the lower pressure plate 77 through a cylinder 74. A second threaded groove 78 is provided on the inner wall of the cylinder 74. Several levers 75 are connected to the side of the cylinder 74. The levers 75 are equidistantly distributed along the circumference of the cylinder 74. The upper pressure plate 76 abuts against the upper plate, and the lower pressure plate 77 abuts against the lower plate.

[0043] The diameter of the third channel 65 is greater than the diameter of the second channel 64. The diameter of the first channel 63 is equal to the diameter of the second channel 64. The inner diameter of the upper plate is the same as the inner diameter of the lower plate. The inner diameter of the upper plate is smaller than the diameter of the cylinder 74.

[0044] A method applied to a geological disaster prevention and control surveying and mapping device, characterized in that: an adjusting screw is inserted into the ground and fixed to the exploration ground; a plate 61 is placed on the exploration ground; a first semicircular plate 31 is pushed, compressing a spring 37; a slider 35 moves from a first position to a second position, separating the first semicircular plate 31 from the second semicircular plate 41; the bottom end of a spiral lifting component passes through a ring plate 46 and approaches the exploration ground; the spiral lifting component is placed between the first and second semicircular plates; the first semicircular plate 31, under the pushing force of the spring 37, abuts against the second semicircular plate 41 and forms a circular plate; the spiral lifting component is rotated to connect with the first threaded hole; the level 44 is observed, and the offset direction of the plate 61 is determined by the position of the bubble; a cylinder 74 is threadedly connected to the adjusting screw; the cylinder 74 is rotated, and the cylinder 74 moves slowly in the vertical direction; the cylinder 74, under the pressure of the upper part of the ring plate 41, moves slowly in the vertical direction. Plate 76 and pressure plate 77 drive plate 61, making plate 61 parallel to the ground. The circular plate is parallel to plate 61, so the circular plate is parallel to the ground. The plane of the circular plate is perpendicular to the axis of the spiral lifting component. At this time, the spiral lifting component is also perpendicular to the ground. Rotate the spiral lifting component, and the tip of the spiral lifting component drills into the ground and reaches the preset depth. The first threaded rod 23 of the spiral lifting component is located below the first threaded groove 43. The spiral lifting component is slidably connected to the first threaded groove 43, pushing the first semicircular plate 31. The first semicircular plate 31 is separated from the second semicircular plate 41. Remove the spiral lifting component. The bottom end of the marker 11 passes through the ring plate 46. The middle part of the marker 11 is slidably connected to the first threaded groove 43. The marker 11 is inserted into the hole opened in the ground, reducing the adjustment time for the auxiliary marker 11 to be inserted into the platform parallel to the ground, improving the accuracy of the vertical insertion of the marker 11 into the survey point, and facilitating the replacement of the marker 11 and the spiral lifting component.

[0045] When using the device, select a relatively flat location as the survey point. Each corner of the plate 61 is equipped with an adjustment screw. Insert the second drill bit 73 of the adjustment screw into the ground so that the plate 61 contacts the ground being surveyed. The circular plate is composed of a first semicircular plate 31 and a second semicircular plate 41. The inner wall of the circular plate has a first threaded groove 43. When the first semicircular plate 31 and the second semicircular plate 41 abut, the first threaded groove 43 is complete. The two grooves 38 extend and intersect at one corner of the plate 61. Pulling the first semicircular plate 31 and moving it towards that corner compresses the spring 37. The first semicircular plate 31, along with the two first wing plates 32, the support plate 34, and the slider 35, moves along the direction of the groove 38. The slider 35 moves from the first position to the second position, separating the first semicircular plate 31 from the second semicircular plate 41. The first rod 21 is placed between the first semicircular plate 31 and the second semicircular plate 41, so that the bottom end of the first drill bit 22 passes through the ring plate 46 and approaches the ground. The first semicircular plate 31 is no longer pulled, and the spring 37 returns to its original position. The spring 37 pulls the slider 35, the first wing plate 32, and the first semicircular plate 31 back to their initial positions. The slider 35 slides from the second position... When moved to the first position, the first semicircular plate 31 abuts against the second semicircular plate 41. The bottom end of the insertion rod 39 passes through the first insertion hole 33, the second insertion hole 36, the third insertion hole 51 in sequence and is inserted into the fourth insertion hole 52, so that the first semicircular plate 31, the support plate 34, and the slider 35 are fixed to the plate 61 as a whole by the insertion rod 39, which can prevent the first semicircular plate 31 and the second semicircular plate 41 from separating or shifting in subsequent operations. The complete first threaded groove 43 is slidably connected to the first rod body 21. Press down the handle 24, and the first threaded rod 23 and the first rod body 21 move vertically downward. When the first threaded rod 23 contacts the first threaded groove 43, turn the handle 24 slightly, and the first threaded rod 23 is threadedly connected to the first threaded groove 43.

[0046] Observe the level 44 on the upper surface of the circular plate. Determine whether the circular plate is level with the ground by the position of the bubble. If the bubble in the level 44 is not in the center of the instrument panel, it means that the circular plate is not parallel to the ground and the tilt angle of the circular plate needs to be adjusted. However, in order to avoid the soil from contacting the first threaded hole during drilling and to ensure the drilling depth, the height of the first rod 21 and the first threaded rod 23 cannot be less than the drilling depth. Therefore, the circular plate needs to be at a certain height from the ground. Because there is a height difference between the circular plate and the ground, it is difficult to directly adjust the circular plate and make it level with the ground. The circular plate is fixedly connected to the plate 61, and the circular plate and the plate 61 are set parallel to each other. The circular plate and the plate 61 move synchronously. The tilt angle of the circular plate is adjusted by fine-tuning the tilt angle of the plate 61. The offset direction of plate 61 is determined by the position of the bubble. If the bubble is to the left, it means that the left side of the level 44 is too high. The left side of plate 61 needs to be lowered or the right side of plate 61 needs to be raised. Find the corresponding adjustment position of plate 61 and rotate lever 75. Lever 75 rotates cylinder 74. Cylinder 74 is threadedly connected to the second threaded rod 72. Cylinder 74 moves along the axis of the second threaded rod 72 with the upper pressure plate 76 and the lower pressure plate 77. If cylinder 74 moves downward, cylinder 74 and the lower pressure plate 77 press against a corner of plate 61 and move plate 61 downward. If cylinder 74 moves upward, cylinder 74 and the upper pressure plate 76 press against a corner of plate 61 and move plate 61 upward. For each rotation of cylinder 74, a corner of plate 61 rises by 0.05-0.1mm. Plate 61 moves slightly under the action of cylinder 74. When the bubble of level 44 moves to the center of the instrument panel, stop rotating lever 75. The circular plate is parallel to the ground, and the axis of the circular plate is perpendicular to the survey point on the ground.

[0047] Turn handle 24, the first threaded rod 23 moves down along the axis of the first threaded hole, the first drill bit 22 drills into the soil and to a predetermined depth to form a borehole. The depth of the borehole is usually greater than 50 cm. The bottom of the borehole passes through the soft soil layer and is located in the solid bottom layer. Remove the insert rod 39, pull the first semicircular plate 31, the spring 37 is compressed, the gap between the first semicircular plate 31 and the second semicircular plate 41 increases, and the spiral lifting component is removed.

[0048] Place the marker 11 between the first semicircular plate 31 and the second semicircular plate 41. The bottom end of the marker 11 passes through the ring plate 46. The first semicircular plate 31 and the second semicircular plate 41 are combined into a circular plate. The flat plate 61 is fixed to the circular plate by the insert rod 39. Alternatively, the flat plate 61 is fixed to the circular plate by the insert rod 39 first, so that the bottom end of the marker 11 passes through the first threaded hole and the ring plate 46 in sequence, and the side piece 12 on the marker 11 is slidably connected to the first corner hole 45 and the second corner hole 47.

[0049] The marker 11 can only move vertically under the limiting effect of the first threaded hole and the inner diameter of the ring plate 46, preventing the marker 11 from shifting during its downward movement. The distance from the side plate 12 to the axis of the marker 11 is slightly larger than the diameter of the borehole. The side plate 12 is a thin plate with a pointed outer edge. The distance from the cutting edge 13 to the axis of the marker 11 gradually decreases vertically. The bottom end of the cutting edge 13 is a cutting tip, which facilitates the side plate 12 in breaking through the soil surface. Finally, the marker 11 and the cutting edge 13 move to the bottom of the borehole and contact the ground through the side plate 12. The marker 11 is unlikely to rotate under wind or external environmental conditions, reducing the possibility of the marker 11 shifting.

[0050] The entire device has a simple structure. The plate 61 is parallel to the circular plate and is fixed to the ground by the adjusting screw. Under the action of the screw thread of the cylinder 74, the height of one corner of the plate 61 is changed, so that the plate 61 and the circular plate are parallel to the ground. The screw lifting component is perpendicular to the ground and completes the drilling. The elasticity is used to control the opening and closing of the circular plate, which facilitates the replacement of the screw lifting component and the marker 11, speeds up the placement of the marker 11, and ensures that the marker 11 is perpendicular to the survey point.
