Description

TECHNICAL FIELD

[0001] The utility model belongs to rock weathering measurement technical field, concretely relates to a device for measuring the weathering and denudation rate of rock surface. BACKGROUND

[0002] Rock surface weathering is the phenomenon of rock breaking, loosening and mineral composition secondary change under the action of solar radiation, atmosphere, water and biology. The measurement of the denudation rate of rock surface weathering is mainly based on the following important reasons:

[0003] The measurement of the denudation rate is helpful to the in-depth understanding of the physical, chemical and biological processes of rock weathering. By comparing the erosion rates under different conditions (such as temperature, humidity, rainfall, rock type, etc.), the main driving factors and mechanisms of weathering can be revealed, which has important significance for the research in the fields of geology, geochemistry and geomorphology. The weathering of rock surface has an important influence on the development and evolution of landforms. By measuring the denudation rate, the future trend of landforms can be predicted, such as the lowering of mountains and the widening of rivers, which has practical application value in geological disaster warning, land use planning and environmental protection. In engineering construction, the weathering degree of rock directly affects its mechanical properties and stability. By measuring the denudation rate, the durability and stability of rock can be evaluated, which provides an important basis for engineering design and construction. For example, in the calculation of pile bearing capacity, the weathering degree of rock and its influence on bearing capacity need to be considered.

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] For example, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an apparatus for measuring the weathering, dissolution, and erosion rate of rock surface includes a measuring frame 1, and further includes a protective measuring mechanism and a laser measuring sensor 207 for protecting the laser measuring sensor 207. The protective measuring mechanism includes a square groove 2 opened on one side of the top of the measuring frame 1. A limiting crossbar 201 is fixedly connected inside the square groove 2. A limiting magnetic block 202 is slidably connected to the outer wall of the limiting crossbar 201. A movable plate 203 is installed on the top of the limiting magnetic block 202. An installation groove 204 is opened at the bottom of the movable plate 203. A telescopic rod 205 is fixedly installed on the top of the inner wall of the installation groove 204. An installation plate 206 is connected to the bottom of the telescopic rod 205. Multiple laser measuring sensors 207 are installed at the bottom of the installation plate 206. A sliding rod 208 is fixedly connected to the side of the installation plate 206 away from the multiple laser measuring sensors 207, and the top of the sliding rod 208 slides to the outer side of the top of the movable plate 203. A pull plate 209 is installed at the top of the sliding rod 208.

[0025] As can be seen from the above, when the staff measures the dissolution and erosion rate of the weathered rock surface, the sliding plate 203 is slidable, so that it slides according to the sliding action between the limiting magnetic block 202 and the inner wall of the square sliding groove 2. This causes the sliding plate 203 to move the multiple laser measuring sensors 207 located at its bottom. When the bottom of the sliding plate 203 moves to the middle position of the measuring frame 1, the mounting plate 206 at the bottom of the sliding plate 203 loses its top pressure effect, which allows the mounting plate 206 to move the multiple laser measuring sensors 207 at its bottom downward, reducing the distance between them and the rock surface. By using the sliding action of the sliding plate 203, the dissolution and erosion rate of the weathered rock surface can be measured.

[0026] It should be noted that the measuring frame 1 is installed on the weathered rock surface, which is existing technology, and its working principle will not be described in detail.

[0027] After the staff completed the measurements of the weathered rock surface, such as Figure 1 As shown, the movable plate 203 is moved to the initial position, and the pull plate 209 is pulled upward, causing the sliding rod 208 to slide upward. This causes the mounting plate 206 to move the laser measuring sensor 207 into the mounting groove 204. When the movable plate 203 slides to the initial position, the bottom of the mounting plate 206 contacts the top of the measuring frame 1, allowing the multiple laser measuring sensors 207 at the bottom of the mounting plate 206 to fit against the top of the measuring frame 1, thus stably protecting them above the measuring frame 1. With this structure, when the laser measuring sensor 207 is not in use, it can be stably protected above the measuring frame 1, preventing excessive dust from adhering to its outer wall. This facilitates the use of the laser measuring sensor 207 for measurement, thereby improving the efficiency of workers using the laser measuring sensor 207 to measure the dissolution and erosion rate of rock surface weathering.

[0028] Specifically, the outer side wall of the limiting magnetic block 202 is in sliding fit with the inner side wall of the square sliding groove 2, one side of the inner wall of the square sliding groove 2 is provided with a mounting magnetic strip, the limiting magnetic block 202 is in corresponding repulsion with the mounting magnetic strip, and the outer side wall of the mounting plate 206 is in sliding fit with the inner side wall of the mounting groove 204;

[0029] As can be seen from the above, according to the sliding fit of the outer side wall of the limiting magnetic block 202 and the mounting plate 206 with the inner side wall of the square sliding groove 2 and the mounting groove 204 respectively, the stability of the sliding of the two in the inner side wall of the square sliding groove 2 and the mounting groove 204 is improved;

[0030] By utilizing the repulsion of the mounting magnetic strip and the limiting magnetic block 202, when the moving plate 203 returns to the initial position, the limiting and fixing effect of the moving plate 203 is improved, and the phenomenon of sliding and separation of the moving plate 203 during carrying of the device is avoided, thereby further improving the protection effect of stable protection of the laser measurement sensor 207;

[0031] Specifically, the top of the mounting groove 204 is provided with a sliding hole, and the sliding hole extends to the top outer side of the moving plate 203, and the top of the sliding rod 208 extends to the top outer side of the moving plate 203 through the sliding hole;

[0032] As can be seen from the above, by utilizing the sliding hole, the sliding rod 208 can be pulled up by the pull plate 209 to pull the mounting plate 206, so that the laser measurement sensor 207 can be stably protected on the temple of the mounting groove 204.

[0033] Specifically, a plurality of scale lines are arranged on the measurement frame 1, and a plurality of cleaning brushes are connected to the bottom of the moving plate 203, and the plurality of cleaning brushes are correspondingly arranged with the plurality of scale lines;

[0034] As can be seen from the above, by utilizing the cleaning brushes, when the moving plate 203 moves, the cleaning brushes can slide and clean above the scale lines by the corresponding arrangement of the cleaning brushes and the scale lines, so that the dust adhering to the outer wall of the scale lines is reduced, which is not conducive to the use of the scale lines;

[0035] Further, the design application is applied to measure the dissolution and erosion rate of weathered rock surface, and the plurality of laser measurement sensors 207 at the bottom of the mounting plate 206 are in fit with the top of the measurement frame 1, so that they are stably protected above the measurement frame 1, and the outer wall of the laser measurement sensor 207 is avoided from adhering to a lot of dust, so that the laser measurement sensor 207 can be conveniently used for measurement, thereby improving the work efficiency of the staff in using the laser measurement sensor 207 to measure the dissolution and erosion rate of the weathered rock surface.

[0036] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
