DETAILED DESCRIPTION

[0025] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0026] Please refer to Figure 1-Figure 2 , which is a schematic diagram of the overall structure of a ruler for geological mapping.

[0027] This embodiment provides a ruler for geological mapping, comprising a circular ruler body 1, a first moving bar 2 and a second moving bar 3.

[0028] The four sides of the circular ruler body 1 are all provided with main scale lines 11, and the zero scale line of the circular ruler body 1 is located at the intersection of two adjacent right-angle sides;

[0029] The first moving strip 2 and the second moving strip 3 cross each other and are parallel to different opposite sides of the circular ruler body 1. The ends of the first moving strip 2 and the second moving strip 3 are slidably connected to the circular ruler body 1 through a vernier scale block 4. The vernier scale block 4 is provided with a vernier scale line 42. The minimum division of the vernier scale line 42 is smaller than the minimum division of the main scale line 11.

[0030] The first moving bar 2 and the second moving bar 3 are both provided with a strip hole 5 along their length direction; wherein, the width of the strip hole 5 is not less than 2 mm; the second moving bar 3 is located above the first moving bar 2, and a positioning block 6 is slidably connected to the second moving bar 3, and the positioning block 6 is provided with a circular hole 61 which is connected to the strip hole 5 and has a diameter of 2 mm.

[0031] Next, a ruler for geological mapping according to this exemplary embodiment will be further described.

[0032] In some embodiments, reference Figure 1 The circular ruler body 1 is a rectangular circular ruler body 1 formed by four rulers connected to each other. The four sides of the circular ruler body 1 are provided with main scale lines 11, and the minimum division of the main scale lines 11 is 1mm (one grid is shown as 2mm in the figure); the zero scale line of the circular ruler body 1 is located at the intersection of two adjacent right-angle sides, forming a two-dimensional plane ruler with horizontal and vertical coordinates with the intersection as the zero scale. When filling geological maps, the zero scale can be quickly located at the coordinate base point; specifically, Figure 1 The zero scale lines of the upper bottom edge and the lower bottom edge of the circular ruler body 1 are located on the left side, and the zero scale lines of the left side and the right side are located on the lower side.

[0033] When marking the location of geological points on a geological mapping field hand map, a coordinate base point can be determined first. The above coordinate base point is a point close to the approximate position of the coordinates of a geological point measured by GPS. For example, if the coordinates of a geological point measured by GPS are: ordinate 4590908, abscissa 548571, then the base point close to the coordinates is determined to be: ordinate 4590000, abscissa 548000.

[0034] By placing the zero scale line of the circular ruler body 1 at the base point, and then finding the corresponding position on the circular ruler body 1 according to the difference between the horizontal and vertical coordinates of the base point and the horizontal and vertical coordinates of the geological point, the geological point can be found and marked on the field hand map.

[0035] In some embodiments, the first moving bar 2 and the second moving bar 3 cross each other and are respectively parallel to different groups of opposite sides of the circular ruler body, and the ends of the first moving bar 2 and the second moving bar 3 are respectively slidably connected to the circular ruler body 1 through a vernier scale block 4, and the vernier scale block 4 is provided with a vernier scale line 42, and the minimum division of the vernier scale line 4 is smaller than the minimum division of the main scale line 11; so that the first moving bar 2 and the second moving bar 3 can slide on the circular ruler body 1 respectively, and can slide the first moving bar 2 and the second moving bar 3 to corresponding positions according to the horizontal and vertical coordinates of the base point and the horizontal and vertical coordinates of the geological point by moving the vernier scale block 4, so that the corresponding grids of the vernier scale line 42 are aligned with the corresponding grids of the main scale line 11, so that the first moving bar 2 and the second moving bar 3 can be accurately positioned, and at this time, the intersection of the first moving bar 2 and the second moving bar 3 is the geological point. For example, the coordinates of the base point are: 4590000 ordinate, 548000 abscissa; the coordinates of the geological point are: 4590908 ordinate, 548571 abscissa; on a hand map with a scale of 1:10,000, its coordinates relative to the base point are: 90.8 mm ordinate, 57.1 mm abscissa. Then move the first moving bar 2 that moves longitudinally from zero scale to the position with a 90.8 mm ordinate, and move the second moving bar 3 that moves transversely from zero scale to the position with a 57.1 mm abscissa, and the intersection is the coordinates of the geological point. Through the above structural design, geological points can be found quickly and accurately.

[0036] The first moving bar 2 and the second moving bar 3 are both provided with a strip hole 5 along their length direction; wherein, the width of the strip hole 5 is not less than 2 mm. The second moving bar 3 is located above the first moving bar 2, and a positioning block 6 is slidably connected to the second moving bar 3, and the positioning block 6 is provided with a circular hole 61 with a diameter of 2 mm. By providing the strip hole 5 and setting the positioning block 6, after locating the geological point, the positioning block 6 can be moved to the intersection of the first moving bar 2 and the second moving bar 3, and a 2 mm circle can be obtained by directly passing through the strip hole 5 through the circular hole 61 on the positioning block 6 to draw a circle, and the circle is the position of the geological point on the hand map. The width of the strip hole 5 is set to be not less than 2 mm, so that the strip hole 5 will not hinder the drawing of a circle through the circular hole 61. Through the above structural design, the geological point can be located quickly and accurately, and the circle specification used to represent the position of the geological point can be obtained.

[0037] As a preferred embodiment, the main scale line 11 is arranged on the inner side of the circular ruler body 1, which is convenient for locating the base point and geological point, and avoids errors caused by being arranged on the outer side. The vernier scale block 4 is slidably mounted on the circular ruler body 1, and an observation hole 41 is opened on the top surface of the vernier scale block 4, and the observation hole 41 is used to expose the main scale line 11 of the circular ruler body 1; the vernier scale line 42 is arranged on one side of the observation hole 41 close to the inner side of the vernier scale block 4 and is opposite to the main scale line 11 up and down, so that the main scale line 11 and the vernier scale line 42 can be aligned, which is convenient for reading and avoids reading errors. Preferably, the vernier scale block 4 is only mounted on the top surface, inner side and outer side of the circular ruler body 1, and the bottom surface of the circular ruler body is not covered by the vernier scale block 4, so that the circular ruler body 1 can be more accurate when locating the base point, and the vernier scale block 4 avoids affecting the initial positioning of the circular ruler body 1 when moving.

[0038] As a preferred implementation method, refer to Figure 2 , the zero scale line of the above-mentioned vernier scale line 42 is located on the side close to the zero scale line of the circular ruler body 1; the above-mentioned main scale line 11 and the vernier scale line 42 are similar to the main scale and vernier scale of the vernier caliper in the prior art, and the minimum division of the vernier scale line 42 is smaller than the minimum division of the main scale line 11, which can improve the accuracy of positioning. The center line of the center of the circular hole 61 is aligned with the center line of the bar hole 5, and the center line of the bar hole 5 is aligned with the zero scale line of the vernier scale line 42 corresponding thereto. Since the center of the circular hole 61 is located on the center line of the bar hole 5, aligning the center line with the zero scale line of the vernier scale line 42 facilitates the rapid positioning between the vernier scale line 42 and the main scale line 11.

[0039] As a preferred embodiment, the minimum division of the main scale line 11 is 1mm, the minimum division of the vernier scale line 42 is 0.9mm, and the difference between the minimum division of the vernier scale line 42 and the minimum division of the main scale line 11 is 0.1mm. Specifically, when the horizontal coordinate is 57.1mm, because the accuracy is required to be 0.1mm, the vernier scale block 4 of the second moving bar 3 is moved to the position where the first grid of the vernier scale line 42 is aligned with 58mm on the main scale line 11. At this time, the difference between the 0 scale line of the vernier scale line 42 and its first grid is 0.9mm, and the reading of the 0 scale line of the vernier scale line 42 is 57.1mm; when the vertical coordinate is 90.8mm, the vernier scale block 4 of the first moving bar 2 is moved to The eighth grid of the vernier scale 42 is aligned with the position of 98mm on the main scale 11. At this time, the 0 scale line of the vernier scale 42 and its eighth grid differ by 7.2mm, and the reading of the 0 scale line of the vernier scale 42 is 90.8mm; the zero scale line of the vernier scale 42 on the first moving bar 2 and the second moving bar 3 is aligned with the center line of the bar hole 5, that is, aligned with the center of the circular hole 61. At this time, the circular hole 61 is moved to the intersection to circle the geological point. By setting the vernier scale 42 on the vernier ruler block 4, the positioning accuracy of the geological point can be improved, and the geological point position can be more accurately marked on the field hand map.

[0040] As a preferred implementation, the zero scale line of the vernier scale line 42 is aligned with the edge of the vernier scale block 4 , so that there is no error between the vernier scale line 42 and the main scale line 11 .

[0041] As a preferred embodiment, the top surface of the vernier scale block 4 extends along the zero scale line of the circular ruler body 1 near the zero scale line to form an extension portion 43; the extension length of the extension portion 43 is not less than 1 / 2 of the width of the first moving bar 2 / the second moving bar 3; the ends of the first moving bar 2 / the second moving bar 3 are connected to the vernier scale block 4 and the extension portion 43. Since the edge of the vernier scale block 4 is aligned with the zero scale line, and the center line of the bar hole 5 is aligned with the zero scale line, in order to avoid the first moving bar 2 or the second moving bar 3 from interfering with the circular ruler body 1 and to ensure a stable connection with the vernier scale block 4, the top surface of the vernier scale block 4 extends a certain distance to the zero scale line side, and the distance is sufficient to connect and fix with the moving bar to improve its stability. Since the moving bar is connected to the top surface of the vernier scale block 4 and the vernier scale block 4 is sleeved on the circular ruler body 1, the moving bar does not affect the movement of the vernier scale block 4 and does not interfere with the circular ruler body 1.

[0042] As a preferred embodiment, the top surfaces of the vernier scale blocks 4 at both ends of the second moving bar 3 are higher than the top surfaces of the vernier scale blocks 4 at both ends of the first moving bar 2, so that the second moving bar 3 does not interfere with the first moving bar 2 when they cross. At the same time, it is only necessary to set the positioning block 6 on a higher moving bar to draw a circle.

[0043] As a preferred embodiment, a slide groove 51 is opened on the top surface of the second movable bar 3, and the positioning block 6 is slidably connected to the slide groove 51, so that the positioning block 6 can be limited in the slide groove 51 without falling off, and can slide along a fixed track without shifting.

[0044] Furthermore, first locking bolts 62 are threadedly penetrated on both sides of the positioning block 6, and the first locking bolts 62 are opposite to the slide groove 51. The positioning block 6 can be fixed by the first locking bolts 62, so as to mark the geological point position by drawing a circle.

[0045] As a preferred embodiment, the outer wall of the vernier scale block 4 is penetrated with a second locking bolt 44, and the second locking bolt 44 is opposite to the outer wall of the circular scale body 1. The vernier scale block 4 can be limited and fixed by the second locking bolt 44, so that the position of the vernier scale block 4 will not be affected when the positioning block 6 moves and draws a circle, thereby preventing it from accidentally moving and causing the position deviation of the geological point.

[0046] Working principle of the embodiment of the present application: Assuming a 1:10000 geological mapping, the ordinate of a geological point measured by a handheld GPS is 4590908 and the abscissa is 548571, then find the intersection of the ordinate 4590000 and the abscissa 548000 on the field hand map, and overlap the intersection with the zero scale line intersection of the circular ruler body 1, and take this point as the "base point". The abscissa of the geological point is theoretically located at a position 57.1mm from the base point, and slide the second moving bar 3 that moves left and right to the vernier scale. The first grid on the line 42 is aligned with the position 58mm away from the base point on the horizontal circular ruler body 1; the longitudinal coordinate of the geological point is theoretically located at a position 90.8mm away from the base point, and the first moving bar 2 that moves up and down is slid to the position where the eighth grid on the vernier scale line 42 is aligned with the position 98mm away from the base point on the longitudinal circular ruler body 1, and then the positioning block 6 is moved to the intersection of the first moving bar 2 and the second moving bar 3. Use a pencil to draw a circle along the circular hole 61 with an inner diameter of 2mm, which is the position of the geological point on the field hand map.
