Description

Technical Field

[0001] This invention relates to the field of geographic information mapping instrument technology, specifically to a portable geographic information mapping instrument for detecting geographic information and its usage method. Background Technology

[0002] Surveying and mapping, literally understood as measuring and drawing, is based on computer technology, optoelectronic technology, network communication technology, space science, and information science. It utilizes Global Navigation Satellite System (GNSS), Remote Sensing (RS), and Geographic Information System (GIS) as its core technologies. It selects existing feature points and boundaries on the ground and obtains graphic and location information reflecting the current state of the ground through measurement methods for use in engineering construction, planning and design, and administrative management. A mapping instrument is a tool used in surveying and mapping operations, capable of collecting, processing, and outputting data; it is commonly used in engineering construction, planning and design, and construction.

[0003] Existing surveying instruments typically use a tripod for support, with a mounting platform at the top to hold the instrument. To ensure surveying accuracy, the tripod needs to be adjusted before surveying to ensure the mounting platform is level. However, in current technology, tripod adjustment is cumbersome and requires multiple people working together: one person adjusts the length of each leg while another observes the level. Adjusting by a single person is time-consuming. Furthermore, the accuracy of tripod adjustment is difficult to guarantee, requiring repeated adjustments. Additionally, surveying instruments are usually stored in a case, while the tripod needs to be carried, making it inconvenient to carry.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0064] Please see Figure 1-12 The present invention will describe the above technical solution in detail through the following embodiments:

[0065] Portable geographic information mapping instruments used for detecting geographic information include:

[0066] Storage bag 1 is used to store the geographic information mapping instrument. Storage bag 1 includes a shoulder strap 18 for the operator to carry.

[0067] The storage bag 1 includes a fixed groove 12, a shoulder strap 18 is fixedly installed on the back of the fixed groove 12, the fixed groove 12 is connected to a movable groove 13 by a hinge, a fixed ring 14 is provided at the top of the fixed groove 12 and the movable groove 13, a limiting plane 15 is provided below the fixed ring 14 and located at the top of the inner side of the fixed groove 12 and the movable groove 13, a partition 16 is placed on the limiting plane 15, and a top cover 11 is threadedly connected above the fixed ring 14.

[0068] The movable slot 13 can rotate around the bottom of the fixed slot 12 via a hinge. After the top cover 11 is removed, the fixed slot 12 and the movable slot 13 can be separated, thereby allowing the internal equipment to be taken out.

[0069] The top and bottom of the outer side of the fixed groove 12 and the movable groove 13 are fixedly installed with bracket buckles 17.

[0070] The surveying instrument 2 is used to measure geographic information. The surveying instrument 2 includes a body 21. The front and rear sides of the body 21 are respectively equipped with an observation eyepiece 22 and an observation objective lens 23. A fixing screw 24 is fixedly installed at the center of the bottom of the body 21, and a handle 25 is fixedly installed on the top surface of the body 21.

[0071] The handle 25 is for human hand gripping, making it convenient to pick up and put down the machine body 21. The observation eyepiece 22 is for human eye observation, and the observation objective lens 23 is for measuring geographical information.

[0072] Also includes:

[0073] The measuring platform 3 includes a support platform 31. A first threaded sleeve 34 is welded to the center of the bottom surface of the support platform 31. A positioning device 35 is threadedly connected to the first threaded sleeve 34. The positioning device 35 is used to locate the surveying point.

[0074] The positioning device 35 uses an infrared emitter. The axis of the infrared emitter is on the same straight line as the axis of the first threaded sleeve 34 of the support platform 31, so that the light emitted by the infrared emitter is on the same straight line as the axis of the first threaded sleeve 34, thus playing a positioning role.

[0075] The support platform 31 is also provided with a level slot 32, in which a level 33 is fixedly installed, and the surveying instrument 2 is located on the top surface of the support platform 31.

[0076] There are three levels 33, which are evenly installed on the support platform 31. When all three levels 33 are level, the support platform 31 is level. The first threaded sleeve 34 is welded to the center of the bottom surface of the support platform 31. The fixing screw 24 passes through the support platform 31 and is threadedly connected to the first threaded sleeve 34, so that the surveying instrument 2 is fixedly installed.

[0077] The bracket fixing assembly 4 is located on the bottom surface of the support platform 31. The bracket fixing assembly 4 includes an insert plate 44 for quick disassembly of the bracket mounting assembly 5. The bracket fixing assembly 4 includes a bracket fixing box 41, which is evenly fixed to the bottom surface of the support platform 31 by screws. The bracket fixing box 41 has a first guide groove 42 inside and a fixing hole 43 through its top surface. The insert plate 44 is slidably mounted on the right side below the fixing hole 43. A sliding rod 45 is threaded to the right side of the top surface of the insert plate 44. The top end of the sliding rod 45 passes through the bracket fixing box 41 and engages with a push plate 46. A return spring 47 is engaged between the push plate 46 and the bracket fixing box 41, with both ends of the return spring 47 abutting against the push plate 46 and the bracket fixing box 41 respectively.

[0078] The return spring 47 provides a force to the push plate 46 away from the bracket fixing box 41, so that the insert plate 44 is positioned to the right of the fixing hole 43 when there is no external force, with the side of the insert plate 44 closest to the fixing hole 43 being inclined. When the push plate 46 is pushed towards the bracket fixing box 41, the return spring 47 is compressed, and the slide rod 45 moves into the bracket fixing box 41, thereby driving the insert plate 44 to move towards the center of the fixing hole 43 until it completely blocks the fixing hole 43. After the push plate 46 is released, the insert plate 44 will return to its original position under the action of the return spring 47.

[0079] The bracket mounting assembly 5 includes a pin 53 for fixing the bracket mounting assembly 5 to the bracket fixing assembly 4; the bracket mounting assembly 5 is connected to the first guide groove 42. The bracket mounting assembly 5 also includes a cover plate 51, which is slidably installed in the first guide groove 42. A connecting block 52 is installed below the cover plate 51 by screws, and a rotating shaft 58 is rotatably installed at the bottom of the connecting block 52.

[0080] The connecting block 52 is provided with a mounting hole 55. The pin 53 is slidably installed in the mounting hole 55. A second return spring 57 is provided below the pin 53 and located in the mounting hole 55. The two ends of the second return spring 57 abut against the bottom surface of the pin 53 and the bottom surface of the mounting hole 55, respectively. The top of the pin 53 is a slope.

[0081] A guide block 54 is provided on the outer side of the bottom of the pin 53. The guide block 54 is integrally formed of metal. A second guide groove 56 is provided on the inner side of the mounting hole 55. The width of the second guide groove 56 is the same as the width of the guide block 54. The angle of the top slope of the pin 53 is the same as the angle of the slope of the fixing hole 43. When the cover plate 51 slides into the first guide groove 42, the top slope of the pin 53 touches the inner top edge of the bracket fixing box 41. The pin 53 is subjected to a downward force, thereby compressing the second return spring 57. The pin 53 retracts into the cover plate 51. When the pin 53 moves to below the fixing hole 43, the pin 53 will rise under the action of the elastic force of the second return spring 57. The pin 53 will lock the fixing hole 43, preventing the bracket mounting assembly 5 from slipping out of the first guide groove 42.

[0082] The fixed bracket 6 can be fixed by using the cooperation of the pin 53 and the fixing hole 43. The insertion plate 44 can be quickly disassembled by pushing the push plate 46. The quick disassembly and assembly of the fixed bracket 6 makes it convenient for operators to carry.

[0083] The fixed bracket 6 includes a handwheel 64, which is connected to a second screw 67 via a bevel gear transmission assembly 66. The handwheel 64 can drive the second screw 67 to rotate via the bevel gear transmission assembly 66. The fixed bracket 6 is connected to a rotating shaft 58. The fixed bracket 6 also includes a rotating bracket 61, which is sleeved on the rotating shaft 58. A main bracket 62 is welded below the rotating bracket 61. The handwheel 64 is mounted on the side of the main bracket 62 and is connected to the bevel gear transmission assembly 66 via a handwheel shaft 65. The main bracket 62 is provided with a third guide groove 63.

[0084] The main support 62 is wider than the rotating support 61. The rotating support 61 can rotate around the pivot 58. When it rotates to a certain angle, the top edge of the main support 62 will lock onto the bottom of the main connecting block 52, thus preventing the main support 62 from rotating too much. The handwheel shaft 65 is mounted through the main support 62. The handwheel 64 is fixedly connected to the handwheel shaft 65. The handwheel 64 can drive the handwheel shaft 65 to rotate, thereby driving the second screw 67 to rotate through the bevel gear transmission assembly 66. A screw fixing plate 68 is installed below the bevel gear transmission assembly 66 and inside the main support 62 by screws. The second screw 67 passes through the screw fixing plate 68. A guide plate 69 is installed at the bottom of the main support 62 by screws.

[0085] The handwheel 64 drives the handwheel shaft 65 to rotate, which in turn drives the second screw 67 to rotate through the bevel gear transmission assembly 66. In conjunction with the threaded sleeve 81 and the level 33, the telescopic bracket 7 can be precisely adjusted without bending over, allowing for single-person operation.

[0086] The telescopic bracket 7 includes a support leg 71. The top of the support leg 71 has a fifth guide groove 75 for mounting a quick-adjustment assembly 8. The telescopic bracket 7 is connected to a third guide groove 63. Second guide blocks 72 are welded to the left and right sides of the top of the support leg 71. The second guide blocks 72 are snap-fitted into the third guide groove 63. The support leg 71 passes through a guide plate 69, and the second guide blocks 72 can slide within the third guide groove 63. The support leg 71 has a through hole 74, and a positioning block 73 is threadedly connected to the bottom end of the support leg 71.

[0087] The inner diameter of the through hole 74 is slightly larger than that of the second screw 67; the positioning block 73 is used to contact the bottom surface, and the top of the positioning block 73 is a four-sided pyramid shape, which can be inserted into the bottom surface to prevent the device from sliding.

[0088] The quick-adjustment assembly 8 includes a threaded sleeve 81, which is threadedly connected to the second screw 67. The threaded sleeve 81 consists of two symmetrical semi-circular sleeves. A second guide plate 82 is welded to the bottom of the threaded sleeve 81. A guide sleeve 83 is welded to the bottom surface of the end of the second guide plate 82. The guide sleeve 83 is slidably installed in the fifth guide groove 75 by a guide bolt 84. A third return spring 85 is sleeved on the guide bolt 84 and located in the fifth guide groove 75. The two ends of the third return spring 85 abut against the bottom surface of the guide sleeve 83 and the fifth guide groove (75) respectively.

[0089] The threaded sleeve 81 has an overall shape that is narrow at the top and wide at the bottom. The third return spring 85 applies a force to the guide sleeve 83 along the axis of the guide bolt 84 towards the head of the guide bolt 84, so that the two threaded sleeves 81 automatically separate without external force, thus separating from the second screw 67.

[0090] The quick adjustment assembly 8 also includes a tapered sleeve 86, which is located at the top of the threaded sleeve 81. A third guide plate 87 is welded to both sides of the bottom of the tapered sleeve 86. A second guide bolt 88 is provided on the third guide plate 87. A fourth return spring 89 is provided on the second guide bolt 88 and above the third guide plate 87. The two ends of the fourth return spring 89 abut against the second guide bolt 88 and the third guide plate 87 respectively. The second guide bolt 88 passes through the third guide plate 87 and is threadedly connected to the support leg 71.

[0091] The inner side of the tapered sleeve 86 is a frustum shape that is narrower at the top and wider at the bottom. The bottom of the tapered sleeve 86 is fitted onto the top of the threaded sleeve 81. The fourth return spring 89 applies a downward force along the axis of the second guide bolt 88 to the third guide plate 87, causing the tapered sleeve 86 to move downward and fit onto the outside of the threaded sleeve 81. Since the inner side of the tapered sleeve 86 is a frustum shape that is narrower at the top and wider at the bottom, the threaded sleeve 81 will move towards the axis of the tapered sleeve 86 to achieve engagement with the second screw 67.

[0092] When the threaded sleeve 81 is engaged with the second screw 67, the rotation of the second screw 67 will cause the threaded sleeve 81 to move along the axis of the second screw 67, thereby causing the support leg 71 to move along the axis of the second screw 67.

[0093] The third return spring 85 can automatically separate the threaded sleeve 81 from the second screw 67, and the fourth return spring 89 can tighten the tapered sleeve to achieve automatic engagement between the threaded sleeve 81 and the second screw 67, enabling rapid adjustment of the length of the telescopic bracket 7.

[0094] The method for using a portable geographic information mapping instrument for detecting geographic information includes the following steps:

[0095] S1: Insert the cover plate 51 of the bracket mounting assembly 5 into the first guide groove 42 until the pin 53 is inserted into the fixing hole 43;

[0096] S2: Lift the tapered sleeve 86 upwards. At this time, the threaded sleeve 81 will move to both sides and separate from the second screw 67 under the elastic force of the third return spring 85. Apply a downward force to the support leg 71 along the axis of the second screw 67, push the support leg 71 out of the main bracket 62 to the required length, and then release the tapered sleeve 86. At this time, the tapered sleeve 86 will move downwards under the elastic force of the fourth return spring 89, so that the threaded sleeve 81 moves down towards the second screw 67 and engages with the second screw 67.

[0097] S3: Rotate the fixed bracket 6 and the telescopic bracket 7 to the required angle and place them securely;

[0098] S4: Rotate handwheel 64, which will drive handwheel shaft 65 to rotate. Handwheel shaft 65 will drive second screw 67 to rotate through bevel gear transmission assembly 66. Rotation of second screw 67 will drive threaded sleeve 81 to move along the axis of second screw 67, thereby driving support leg 71 to move. Fine-tune the length of support leg 71 extending from main bracket 62 until level 33 shows horizontal and positioning instrument 35 shows that the center of support platform 31 is directly above the survey point.

[0099] S5: Hold the top handle 25 of the machine body 21, align the fixing screw 24 at the bottom of the machine body 21 with the first threaded sleeve 34, rotate the machine body 21 until the bottom surface of the machine body 21 abuts against the top surface of the support platform 31, install the surveying instrument 2 on the support platform 31, put your eye close to the observation eyepiece 22, and perform surveying through the observation objective lens 23.

[0100] S6: After the survey is completed, hold the top handle 25 of the machine body 21 and rotate the machine body 21 in the opposite direction until the fixing screw 24 is separated from the first threaded sleeve 34, and remove the machine body 21 from the support platform 31.

[0101] S7: Push the push plate 46. The push plate 46 drives the insert plate 44 to move toward the center of the fixing hole 43 via the slide rod 45 until the push plate 46 can no longer move. At this time, the insert plate 44 will push the pin 53 out of the fixing hole 43.

[0102] S8: Remove the cover plate 51 from the first guide groove 42, then lift the tapered sleeve 86 and apply an upward force to the support leg 71 along the axis of the second screw 67 to retract the support leg 71 into the main bracket 62.

[0103] S9: Place the surveying instrument 2 and the measuring platform 3 into the storage bag 1, and insert the fixed bracket 6 into the bracket buckle 17.
