[0002] In the current geological exploration work, the exploration engineering original geological recording is an important basic work, and the standardization, rigor, authenticity and objectivity of the recording have important significance for the research and report preparation of the geological results. At present, there is an important work called trench exploration in the geological exploration and mining engineering, which needs to dig a exploration trench with a depth not more than 3m on the ground. When recording the exploration trench, a tape measure is generally needed to be pulled along the exploration trench as a baseline, and the position of the tape measure (baseline) is taken as the 0 scale. When recording the exploration trench, the box ruler is needed to measure the distance between the surface topographic line, the bedrock boundary and the bottom of the trench and the 0 scale. At present, the box ruler is used to measure the distance between the surface topographic line, the bedrock boundary and the bottom of the trench and the 0 scale separately, which leads to complicated measurement, and when measuring the distance, the tape measure (baseline) is not always close to the trench wall, so the recording personnel need to align by visual inspection at this time, or when the measured distance is large, the box ruler cannot keep vertical state, which is easy to cause error.

[0021] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0022] Please refer to Figures 1-3 , the overall structure of the schematic diagram of the ruler for trench logging,
[0023] The present embodiment provides a kind of ruler for trench logging, including first housing 1 and the ruler 2 of sliding connection in the inside of first housing 1,
[0024] Ruler 2 is provided with division line 21 along its length direction;Division line 21 is divided into upper division line 211 and lower division line 212 by zero scale, the length of upper division line 211 is less than the length of lower division line 212, and upper division line 211 is located at the end away from first housing 1;
[0025] Ruler 2 is slidably connected with slider 3, and slider 3 is hinged with crossbar 4.
[0026] Below, a kind of ruler for trench logging of the present exemplary embodiment will be further described.
[0027] In some embodiments, refer to Figure 1The first shell 1 is a hollow shell with a fixed length. The ruler 2 is slidingly connected to the first shell 1 to form a length-adjustable ruler together with the first shell 1, i.e., the total length of the ruler 2 and the first shell 1 is adjusted by extending or retracting the ruler 2. The ruler 2 is provided with scale lines 21 along the length direction thereof, and the scale lines 21 are divided into upper scale lines 211 and lower scale lines 212 by zero scale lines. The length of the upper scale lines 211 is smaller than that of the lower scale lines 212, and the upper scale lines 211 are located at the end away from the first shell 1. The upper scale lines 211 are used to measure the distance between the ground surface terrain line and the base line, and the distance is small because the base line is located near the top of the trench, so the upper scale lines 211 with a small length are used to measure the distance. The lower scale lines 212 are used to measure the distance between the bottom of the trench and the base line, and the distance is large because the trench has a certain depth, so the lower scale lines 212 with a large length are used to measure the distance. When working, it is observed whether the bedrock boundary line is above or below the base line. If the bedrock boundary line is above the base line, the distance between the bedrock boundary line and the base line on the upper scale lines 211 is read. If the bedrock boundary line is below the base line, the distance between the bedrock boundary line and the base line on the lower scale lines 212 is read.
[0028] As Figure 2 measuring, the first shell 1 is placed at the bottom of the trench, and the ruler 2 is pulled out to a certain distance until the zero scale line on the ruler 2 is aligned with the base line. At this time, the reading H1 below the zero scale line (the lower scale lines 212) plus the length H2 of the first shell 1 is the distance between the bottom of the trench and the base line, and the reading h1 above the zero scale line (the upper scale lines 211) is the distance between the ground surface terrain line and the base line. If the bedrock boundary line is above the base line, the reading h2 above the zero scale line (the upper scale lines 211) is the distance between the bedrock boundary line and the base line. If the bedrock boundary line is below the base line, the reading h3 below the zero scale line (the lower scale lines 212) is the distance between the bedrock boundary line and the base line.
[0029] In a specific embodiment, the upper scale line part above the zero scale line on the ruler 2 is set to 60 cm, the lower scale line part below the zero scale line is set to two sections, each section is 100 cm, and the first shell 1 is set to 100 cm. The first shell 1 can be marked as 0 cm-100 cm. Different sizes of scales can also be set according to actual needs.
[0030] In some embodiments, the ruler 2 is slidingly connected with a sliding block 3, and the sliding block 3 is hingedly connected with a horizontal rod 4. The horizontal rod 4 can be moved along the ruler 2 by the sliding block 3, and the horizontal rod 4 can be rotated to be perpendicular to the ruler 2 or overlapped with the ruler 2 by being hingedly connected to the sliding block 3. The perpendicular state is convenient for measurement, and the overlapped state is convenient for storage.
[0031] Specifically, when the baseline is not close to the groove wall, there is a certain distance between the ruler 2 and the baseline, which makes it difficult to align the ruler 2 with the baseline when reading, and is easy to cause errors. At this time, by rotating the crossbar 4 to be perpendicular to the ruler 2, the baseline is aligned with the scale line 21 of the ruler 2 through the crossbar 4, so that the reading can be quickly obtained, and the measurement accuracy is improved.
[0032] As a more preferred embodiment, the above-mentioned crossbar 4 is a telescopic rod, which can adjust the length of the crossbar 4 according to the actual use requirement.
[0033] As a more preferred embodiment, the maximum rotation angle of the above-mentioned crossbar 4 is 90°, and when the crossbar 4 is rotated by 90°, the crossbar 4 is perpendicular to the ruler 2. By limiting the rotation angle of the crossbar 4, when the crossbar 4 is rotated to be perpendicular to the ruler 2, the crossbar 4 cannot be further rotated, which can avoid the rotation of the crossbar 4 under the action of gravity during the leveling process, and can also free the hands of the workers, so that they do not need to hold the crossbar 4.
[0034] As a more preferred embodiment, with reference to Figure 1 and Figure 3 the side of the above-mentioned first shell 1 is provided with a second shell 5, and the second shell 5 is used to accommodate the crossbar 4. The first shell 1 is used to accommodate the ruler 2, and the second shell 5 is used to accommodate the crossbar 4, so that when it is stored, the ruler can be contracted to the shortest length and the smallest volume, which is convenient for storage and carrying, as shown in Figure 3 .
[0035] As a more preferred embodiment, the above-mentioned sliding block 3 is sleeved on the ruler 2, and the sliding block 3 is provided with a first locking bolt 31, which is used to lock the sliding block 3 on the ruler 2. The sliding block 3 is locked and fixed during measurement, so as to avoid displacement of the sliding block 3 and the crossbar 4.
[0036] As a more preferred embodiment, the side wall of the above-mentioned first shell 1 is provided with a second locking bolt 11, which is used to lock the ruler 2 on the first shell 1. After the ruler 2 is pulled out to a specified length during measurement, it is locked, which can avoid the ruler 2 from retracting during measurement and affecting the measurement accuracy.
[0037] As a more preferred embodiment, the side wall of the above-mentioned first shell 1 is provided with a length identifier 12, which corresponds to the total length of the first shell 1. By providing the length identifier 12, the length of the first shell 1 can be quickly obtained, and then the scale of the ruler 2 can be quickly summed up during measurement to obtain the height of the groove bottom.
[0038] The working principle of the embodiment of the application is as follows: during measurement, the first shell 1 is placed on the groove bottom, the internal scale 2 is pulled out to a certain length, the 0 scale of the scale 2 is aligned with the base line, the crossbar 4 is rotated to be perpendicular to the scale 2, the sliding block 3 is slid to move to the position where the 0 scale is aligned with the base line, alignment of the two is ensured, if the two are not aligned, the pull-out length of the scale 2 is adjusted to make the two aligned. At this time, the sum of the pull-out scale of the lower scale line 212 of the scale 2 and the length of the first shell 1 is the distance from the groove bottom to the base line. The sliding block 3 is moved to the upper scale line 211 part to make the crossbar 4 aligned with the ground surface, at this time, the scale of the upper scale line 211 aligned with the crossbar 4 is the distance from the ground surface to the base line. If the bedrock boundary line is above the base line, the sliding block 3 is moved to the upper scale line 211 part to make the crossbar 4 aligned with the bedrock boundary line, at this time, the scale of the upper scale line 211 aligned with the crossbar 4 is the distance from the bedrock boundary line to the base line; if the bedrock boundary line is below the base line, the sliding block 3 is moved to the lower scale line 212 part to make the crossbar 4 aligned with the bedrock boundary line, at this time, the scale of the lower scale line 212 aligned with the crossbar 4 is the distance from the bedrock boundary line to the base line. The application can simultaneously measure the distances from the ground surface, the bedrock boundary line and the groove bottom to the base line, and the operation is simple, fast and high in measurement accuracy.
