Description

Technical Field

[0001] This utility model relates to the field of geological mapping, and more specifically, to a ruler for geological mapping. Background Technology

[0002] Geological mapping is a fundamental task in geological and mineral exploration. Geological maps of different scales are created according to the requirements of each exploration stage, providing basic geological data for exploration. When conducting geological mapping, a field map must be carried at all times. The locations of the geological points determined during the mapping process are then marked on the field map using a 2mm diameter circle based on the coordinates of the geological points obtained from GPS. Currently, the most common method for marking geological points is to first measure the horizontal and vertical coordinates of the geological points on the field map using a set square, and then draw a 2mm diameter circle using a compass. However, this method requires carrying a set square, compass, and ink, making it inconvenient and resulting in inaccurate markings. When the center of the compass does not coincide with the geological point, the marking error becomes large, and the drawn circles are not very standardized. Utility Model Content

Detailed Implementation

[0025] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0026] Please refer to Figures 1-2 The image shows a schematic diagram of the overall structure of a ruler used for geological mapping.

[0027] This embodiment provides a ruler for geological mapping, including a rectangular ruler body 1, a first movable strip 2, and a second movable strip 3.

[0028] The four sides of the spiral ruler 1 are provided with main scale lines 11, and the zero scale line of the spiral ruler 1 is located at the intersection of two adjacent right-angled sides.

[0029] The first moving strip 2 and the second moving strip 3 are arranged vertically and are parallel to different sets of opposite sides of the spiral ruler body, and the ends of the first moving strip 2 and the second moving strip 3 are slidably connected to the spiral ruler body 1 through the slider 4; both the first moving strip 2 and the second moving strip 3 have strip-shaped holes 5 along their length direction; wherein the width of the strip-shaped hole 5 is not less than 2mm.

[0030] The second moving strip 3 is located above the first moving strip 2. A positioning block 6 is slidably connected to the second moving strip 3. The positioning block 6 has a circular hole 61 with a diameter of 2mm.

[0031] The following will further describe a ruler for geological mapping according to this exemplary embodiment.

[0032] In some implementations, refer to Figure 1 The aforementioned rectangular ruler 1 is formed by connecting four rulers. Each of the four sides of the ruler 1 has a main scale line 11, with a minimum division of 1mm (one division in the figure is shown as 2mm). The zero mark of the ruler 1 is located at the intersection of two adjacent right-angled sides, forming a two-dimensional plane ruler with the intersection as the zero mark. During geological mapping, this zero mark can be quickly positioned at the coordinate base point. Specifically, as shown... Figure 1 The zero mark lines on the top and bottom edges of the ruler body 1 are located on the left side, while the zero mark lines on the left and right sides are located on the bottom side.

[0033] When marking geological points on a field map for geological mapping, a coordinate base point can be determined first. This base point is a point approximately located close to the coordinates of a geological point determined by GPS measurements. For example, if the coordinates of a geological point measured by GPS during a 1:10000 geological mapping process are 4590908 (ordinate) and 548571 (axophone), then the base point approximately located close to these coordinates on the 1:10000 field map would be 4590000 (ordinate) and 548000 (axophone).

[0034] By placing the zero mark of the spiral ruler 1 at the base point, and then finding the corresponding position on the spiral ruler 1 based on 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 located and marked on the field map.

[0035] In some embodiments, the first moving strip 2 and the second moving strip 3 are vertically arranged and parallel to different sets of opposite sides of the circular ruler body, and the ends of the first moving strip 2 and the second moving strip 3 are slidably connected to the circular ruler body 1 via sliders 4, so that the first moving strip 2 and the second moving strip 3 can slide on the circular ruler body 1 respectively. 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 first moving strip 2 and the second moving strip 3 are slid to the corresponding positions, and the intersection of the first moving strip 2 and the second moving strip 3 is the geological point. For example, the coordinates of the base point are: vertical coordinate 4590000, horizontal coordinate 548000; the coordinates of the geological point are: vertical coordinate 4590908, horizontal coordinate 548571; on a 1:10,000 scale hand map, its coordinates relative to the base point are: vertical coordinate 90.8mm, horizontal coordinate 57.1mm. The first vertical moving strip 2 is moved from the zero mark to a position with a vertical coordinate of 90.8 mm, and the second horizontal moving strip 3 is moved from the zero mark to a position with a horizontal coordinate of 57.1 mm. The intersection of these two strips is the coordinate of the geological point. Through the above structural design, geological points can be located quickly and accurately.

[0036] Both the first moving strip 2 and the second moving strip 3 have strip-shaped holes 5 along their length; the width of the strip-shaped holes 5 is not less than 2mm. The second moving strip 3 is located above the first moving strip 2, and a positioning block 6 is slidably connected to the second moving strip 3. The positioning block 6 has a circular hole 61 with a diameter of 2mm. By creating the strip-shaped holes 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 strip 2 and the second moving strip 3. A 2mm circle can be obtained by drawing a circle directly through the circular hole 61 on the positioning block 6, which represents the position of the geological point on the hand map. Setting the width of the strip-shaped holes 5 to not less than 2mm ensures that the strip-shaped holes 5 do not obstruct the drawing of a circle through the circular hole 61. Through the above structural design, geological points can be quickly and accurately located, and the circles used to represent the positions of geological points are standardized.

[0037] In a preferred embodiment, the slider 4 is slidably fitted onto the spiral ruler 1. An observation hole 41 is provided on the top surface of the slider 4 to expose the main scale line 11 of the spiral ruler 1. Preferably, the slider 4 is only fitted onto the top surface, inner side, and outer side of the spiral ruler 1, and the bottom surface of the spiral ruler 1 is not covered by the slider 4. This allows the spiral ruler 1 to be more accurately positioned at the base point, and the slider 4 avoids affecting the initial positioning of the spiral ruler 1 when it moves.

[0038] As a preferred implementation method, refer to Figure 2The top surface of the slider 4 is provided with a vernier scale line 42 opposite to the main scale line 11. The minimum division of the vernier scale line 42 is smaller than that of the main scale line 11. The zero mark of the vernier scale line 42 is located on the side closer to the zero mark of the ruler body 1. The main scale line 11 and the vernier scale line 42 are similar to the main scale and vernier scale of a vernier caliper in the prior art. The smaller minimum division of the vernier scale line 42 compared to the main scale line 11 improves the positioning accuracy. The center line of the circular hole 61 is aligned with the center line of the strip hole 5, and the center line of the strip hole 5 is aligned with the zero mark of the corresponding vernier scale line 42. Since the center of the circular hole 61 is located on the center line of the strip hole 5, aligning the center line with the zero mark of the vernier scale line 42 facilitates rapid positioning between the vernier scale line 42 and the main scale line 11.

[0039] In a preferred embodiment, the minimum graduation of the main scale line 11 is 1 mm, and the minimum graduation of the vernier scale line 42 is 0.9 mm. The minimum graduation of the vernier scale line 42 differs from the minimum graduation of the main scale line 11 by 0.1 mm. Specifically, when the horizontal coordinate is 57.1 mm, since accuracy to 0.1 mm is required, the slider 4 of the second moving bar 3 is moved to the position where the first division of the vernier scale line 42 aligns with 58 mm on the main scale line 11. At this time, the 0 mark of the vernier scale line 42 differs from its first division by 0.9 mm, so the reading of the 0 mark of the vernier scale line 42 is 57.1 mm. When the vertical coordinate is 90.8 mm, the slider 4 of the first moving bar 2 is moved to the position where the vernier scale line 42 aligns with 58 mm on the main scale line 11. When the eighth division of the scale line 42 aligns with the 98mm mark on the main scale line 11, the difference between the 0 mark of the vernier scale line 42 and its eighth division is 7.2mm, so the 0 mark reading of the vernier scale line 42 is 90.8mm. When the zero mark of the vernier scale line 42 on the first moving bar 2 and the second moving bar 3 aligns with the center line of the strip hole 5, that is, with the center of the circular hole 61, moving the circular hole 61 to the intersection point allows for drawing circles around the geological points. By setting the vernier scale line 42 on the slider 4, the positioning accuracy of the geological points can be improved, allowing for more precise marking of the geological point locations on the field map.

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

[0041] In a preferred embodiment, the top surface of the slider 4 extends along the zero mark of the ruler 1 near the zero mark, forming an extension 43. The extension length of the extension 43 is not less than half the width of the first moving strip 2 / second moving strip 3. The ends of the first moving strip 2 / second moving strip 3 are connected to the slider 4 and the extension 43. Since the edge of the slider 4 is aligned with the zero mark, and the center line of the strip hole 5 is aligned with the zero mark, in order to avoid interference between the first moving strip 2 or the second moving strip 3 and the ruler 1, and to ensure a stable connection with the slider 4, the top surface of the slider 4 extends a certain distance to the zero mark side. This distance is sufficient to connect and fix the moving strip, thereby improving its stability. Since the moving strip is connected to the top surface of the slider 4, and the slider 4 is fitted onto the ruler 1, the moving strip does not affect the movement of the slider 4 and does not interfere with the ruler 1.

[0042] In a preferred embodiment, the top surfaces of the sliders 4 at both ends of the second moving bar 3 are higher than the top surfaces of the sliders 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 intersect. At the same time, only the positioning block 6 needs to be set on the higher moving bar to draw circles.

[0043] In a preferred embodiment, the top surface of the second moving strip 3 is provided with a groove 51, and the positioning block 6 is slidably connected to the groove 51, so that the positioning block 6 can be confined within the groove 51 without falling off, and can slide along a fixed trajectory without shifting.

[0044] Furthermore, the positioning block 6 is threaded with first locking bolts 62 on both sides, 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, which facilitates marking the geological point positions.

[0045] In a preferred embodiment, a second locking bolt 44 is provided on the outer wall of the slider 4, and the second locking bolt 44 is opposite to the outer wall of the spiral ruler body 1. The slider 4 can be limited and fixed by the second locking bolt 44, so that the position of the slider 4 will not be affected when the positioning block 6 moves or when drawing circles, thus avoiding accidental movement and deviation of the geological point position.

[0046] The working principle of this application embodiment is as follows: Assuming a 1:10000 geological mapping, the vertical coordinate of a geological point measured by a handheld GPS is 4590908, and the horizontal coordinate is 548571. Then, the intersection of the vertical coordinate 4590000 and the horizontal coordinate 548000 is found on the field map. This intersection is then aligned with the zero mark of the ruler 1. This point is taken as the "base point". Theoretically, the horizontal coordinate of this geological point is located 57.1 mm away from the base point. The second moving bar 3, which moves left and right, is then slid to the vernier scale. The first grid on line 42 is aligned with the horizontal spiral ruler 1 at a distance of 58mm from the base point. The vertical coordinate of this geological point is theoretically located at a distance of 90.8mm from the base point. Slide the first moving bar 2, which moves up and down, to the eighth grid on the vernier scale line 42, which is aligned with the vertical spiral ruler 1 at a distance of 98mm from the base point. Then move the positioning block 6 to the intersection of the first moving bar 2 and the second moving bar 3. Draw a circle with a pencil along the 2mm inner diameter hole 61 to get the location of the geological point on the field map.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.
