Description

Technical Field

[0001] This invention relates to the field of geological surveying tools, specifically to a geological core sampling ruler. Background Technology

[0002] In geological exploration, it is often necessary to sample and analyze core samples obtained from drilling to determine stratigraphic boundaries or delineate mineral boundaries. The current technical approach involves loggers measuring the core length per run on-site, calculating the core recovery rate based on the run's footage, and then calculating the core length of each sample in the lab using a calculator or manually in the field, based on the run's footage and sample length. This determines the sampling location, which is then compiled into a core splitting table. After verification, the samples are marked and split on-site. However, calculating the core splitting table using a calculator requires multiple trips between the field and lab, and any adjustments to sample length necessitate recalculating all sampling locations after the adjustment, impacting efficiency. Manual calculation is time-consuming, labor-intensive, and prone to errors, especially when collecting large quantities of core or mineral samples, making accurate and rapid calculation of sampling locations a significant challenge for sampling workers. Summary of the Invention

[0003] To address the problems existing in current technologies, this invention provides a geological core sampling ruler that enables convenient and intuitive measurement of sample sampling locations on-site, improving on-site work efficiency. Specifically, it includes the following:

Each of the main ruler, the first auxiliary ruler, and the second auxiliary ruler includes a first end and a second end, and each of the three rulers has length graduation lines from the first end to the second end. The main ruler has a length guide groove running through its front and rear sides. The first end of the first auxiliary ruler is rotatably connected to the first end of the main ruler; the first end of the second auxiliary ruler is rotatably connected to the second end of the first auxiliary ruler. The sliding connecting device includes a third connecting column, a column cap, and an elastic device. The third connecting column has a first end and a second end, the first end of which is connected to the second end of the second auxiliary ruler, and the second end of the third connecting column passes through the length guide groove and is located on the other side of the main ruler.

[0006] Preferably, the main ruler, the first auxiliary ruler, and the second auxiliary ruler each include a front side and a rear side. The rear side of the first auxiliary ruler is connected to the front side of the main ruler, and the front side of the second auxiliary ruler is connected to the rear side of the first auxiliary ruler.

The 50% to 100% core recovery rate graduations are evenly divided.

[0011] Preferably, the sum of the lengths of the first and second auxiliary rulers from the first and second ends is equal to the lengths of the first and second ends of the main ruler.

Furthermore, the complete contents of the configurations illustrated in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0020] A geological core sampling ruler includes a main ruler 1, a first auxiliary ruler 2, a second auxiliary ruler 3, and a sliding connection device. Each of the main ruler 1, the first auxiliary ruler 2, and the second auxiliary ruler 3 includes a first end and a second end. Each of the main ruler 1, the first auxiliary ruler 2, and the second auxiliary ruler 3 has length graduation lines from the first end to the second end. The main ruler 1 has a length guide groove 7 that runs through its front and rear sides. The first end of the first auxiliary ruler 2 is rotatably connected to the first end of the main ruler 1. The first end of the second auxiliary ruler 3 is rotatably connected to the second end of the first auxiliary ruler 2. The sliding connection device includes a third connecting post 8, a post cap 9, and an elastic device 10. The third connecting post 8 includes a first end and a second end. The first end of the third connecting post 8 is connected to the second end of the second auxiliary ruler 3. The second end of the third connecting post 8 passes through the length guide groove 7 and is located on the other side of the main ruler 1. The post cap 9 is located at the end of the second end of the third connecting post 8. The elastic device 10 is sleeved on the third connecting post 8 and located between the post cap 9 and the main ruler 1. Preferably, the distance between the starting and ending scales of the length scale line of the main scale 1 is 1m, and the distance between the starting and ending scales of the first auxiliary scale 2 and the second auxiliary scale 3 is 0.5m.

[0021] In one embodiment of the present invention, a first connecting post 5 and a pad 4 are further included. The two ends of the first connecting post 5 are respectively connected to the first end of the first auxiliary ruler 2 and the first end of the main ruler 1. The first end of the first auxiliary ruler 2 and the first end of the main ruler 1 are rotatably connected through the first connecting post 5. The pad 4 is sleeved on the first connecting post 5 between the first end of the first auxiliary ruler 2 and the first end of the main ruler 1.

[0022] In one embodiment of the present invention, the main ruler 1, the first auxiliary ruler 2, and the second auxiliary ruler 3 each include a front side and a rear side. The rear side of the first auxiliary ruler 2 is connected to the front side of the main ruler 1, and the front side of the second auxiliary ruler 3 is connected to the rear side of the first auxiliary ruler 2. The thickness of the pad block 4 is equal to the thickness of the second auxiliary ruler 3.

[0023] In one embodiment of the present invention, a second connecting post 6 is further included. The two ends of the second connecting post 6 are respectively connected to the second end of the first auxiliary ruler 2 and the first end of the second auxiliary ruler 3. The first end of the second auxiliary ruler 3 and the second end of the first auxiliary ruler 2 are rotatably connected through the second connecting post 6.

[0024] In one embodiment of the present invention, both ends of the length guide groove 7 are arc-shaped.

[0025] In one embodiment of the present invention, the length guide groove 7 includes a first end and a second end, the second end of the length guide groove 7 being located at the second end of the main scale 1; the main scale 1 is provided with a core recovery rate scale line along the direction from the first end to the second end of the length guide groove 7.

[0026] In one embodiment of the present invention, the first end of the length guide groove 7 is located at the center of the first and second ends of the main scale 1. The core recovery rate is graduated from 50% to 100%, with the 50% core recovery rate graduation line coinciding with the 10.5m length graduation line on the main scale, and the 100% core recovery rate graduation line coinciding with the 11m length graduation line on the main scale. The 50% to 100% core recovery rate graduations are evenly divided.

[0027] In one embodiment of the present invention, the sum of the length of the first auxiliary ruler 2 from the first end to the second end and the length of the second auxiliary ruler 3 from the first end to the second end is equal to the length of the first end and the second end of the main ruler 1. Thus, when the sliding connecting device slides to the second end of the length guide groove 7, the first auxiliary ruler 2 and the second auxiliary ruler 3 are exactly in a straight line and parallel to the main ruler 1.

[0028] In one embodiment of the present invention, the elastic device 10 is a telescopic spring. The function of the elastic device 10 is to both facilitate the sliding of the sliding connection device in the length guide groove 7, thus allowing for convenient position adjustment, and to provide a certain degree of fixation.

[0029] In one embodiment of the present invention, the geological core sampling ruler includes a main ruler 1, a first auxiliary ruler 2, and a second auxiliary ruler 3. The main ruler 1, the first auxiliary ruler 2, and the second auxiliary ruler 3 are all provided with length graduation lines. A pad 4 is provided at one end of the main ruler 1. The pad 4 is hinged to one end of the first auxiliary ruler 2 via a first connecting post 5. The center of the first connecting post 5 coincides with the starting graduation line of both the main ruler 11 and the second auxiliary ruler 3. The other end of the first auxiliary ruler 2 and one end of the second auxiliary ruler 3 are hinged via a second connecting post 6. The center of the second connecting post 6 coincides with the end of the first auxiliary ruler 2. The scale extension lines of the main scale 1 and the starting scale extension lines of the second auxiliary scale 3 are all coincident. The other end of the main scale 1 is provided with a length guide groove 7, which is provided with a core recovery rate scale line. The other end of the second auxiliary scale 3 is fixedly connected to a third connecting column 8. The third connecting column 8 passes through the length guide groove 7 and can move along the length guide groove 7. The third connecting column 8 is connected to a column cap 9, which is located below the length guide groove 7. When the core sampling scale is closed, the center of the third connecting column 8 coincides with the end scale extension line of the main scale 1. The main scale 1, the first auxiliary scale 2, and the second auxiliary scale 3 can all move relative to each other.

[0030] When the core sampling ruler disclosed in this invention is in operation, the main ruler 1 is first placed on the core to be sampled. The main ruler 1 is parallel to the core axis, and the starting scale of the main ruler 1 coincides with the starting point of the core to be sampled. According to the calculated core recovery rate of the sampling round, the center of the third connecting column 8 is slid in the length guide groove 7 to the corresponding core recovery rate scale line position. The sample length of the sampling round is read on the first auxiliary ruler 2 or the second auxiliary ruler 3 and vertically projected onto the main ruler 1. The length scale line corresponding to the main ruler 1 is the core length. The core length calculation and measurement are completed simultaneously.

[0031] The main scale 1 of the core sampling ruler of this invention has a starting and ending scale distance of 1m, and the starting and ending scale distances of the first auxiliary scale 2 and the second auxiliary scale 3 are both 0.5m. When the sample length of the proposed sampling round is between 0 and 0.5m, the scale of the first auxiliary scale 2 is read. When the sample length of the proposed sampling round is between 0.5 and 1m, the scale of the second auxiliary scale 3 is read. When the proposed sampling round spans multiple rounds, measurements can be performed separately for each round.

[0032] In addition, according to the "Specifications for Solid Mineral Exploration" and the construction quality requirements for drilling engineering, the core recovery rate should generally be greater than 70%, and the mineral core recovery rate should be greater than 80%. Considering redundancy design, the core recovery rate scale is set to 50% to 100%. The 50% core recovery rate scale line coincides with the 10.5m long scale extension line of the main scale, and the 100% core recovery rate scale line coincides with the 11m long scale extension line of the main scale. The 50% to 100% core recovery rate scale is evenly divided.

[0033] In addition, the two ends of the length guide groove 7 are arc-shaped, and the shape and size of the third connecting post 8 match the shape and size of the strip through hole to ensure that the center of the third connecting post 8 can be accurately aligned with the core recovery rate scale when sliding.

[0034] In addition, the main ruler 1, the first auxiliary ruler 2, and the second auxiliary ruler 3 are made of transparent material.

[0035] In addition, to prevent the second scale 3 from wobbling up and down during sliding, and to ensure that the center of the third connecting column 8 is temporarily fixed after being aligned with the core recovery rate scale, an elastic device 10 is provided between the column cap 9 and the main scale 1.

[0036] In addition, the elastic device 10 is a telescopic spring, which is wrapped around the lower outer periphery of the third connecting post 8.
