Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a geological compass device for measuring the occurrence of high-distance fissures. Background Art

[0002] When conducting underground geological survey operations in adits and tunnels, the geological conditions are complex, and after the adit and tunnel are excavated, different structures develop differently, so the conditions exposed in the cave are different. When some more obvious structural cracks are exposed in the top arch of the adit or tunnel, or in places that are difficult to reach due to other factors, it is often difficult to fully collect the correct occurrence of the crack surface.

[0003] In geological work, measuring the occurrence of strata, structures, and fissures is one of the basic geological work. The method of measuring the occurrence is generally to place one side of the compass close to the measured surface, keep the compass horizontal, read the angle of the compass, and when measuring the inclination, place the compass upright on the measured surface, adjust the angle of the inclination needle, make the level above horizontal, and read the inclination reading. However, this method has many limitations. First, the compass needs to be placed close to the measured surface. Second, when the measured surface only has one crack and no surface exposed, it is difficult to ensure that the connected surface is consistent with the side surface by connecting a plane outside the crack, and the error is also large. Third, when the measured surface is exposed in a place that is difficult for us to touch due to environmental, height, safety and other factors, it is impossible to accurately measure the occurrence of the measured surface.

[0004] Based on the above problems, it is urgent to develop a measuring device that can accurately measure the difficult-to-reach measured surface to solve the existing exploration problems. Utility Model Content

[0005] The utility model aims to solve the deficiencies of the prior art and to provide a geological compass device for measuring the occurrence of long-distance fractures. The direction and inclination of the fractures can be obtained through fan-shaped laser rays, which can provide accurate occurrence of the measured surface, ensure the safety of engineers, and provide scientific and safe scientific data for geological exploration.

[0006] The utility model is realized by the following technical solutions:

[0007] A geological compass device for measuring the occurrence of long-distance fractures, comprising:

[0008] A compass device box, wherein the compass device box has a chamber on its side, and the chamber has a laser transmitter, a rotating disk and a driving member;

[0009] The rotating disk is rotatably connected in the chamber, and the axis of the rotating disk is perpendicular to the front side of the compass device box; the laser emitter is arranged at an eccentric position in front of the rotating disk; the laser emitter can emit fan-shaped laser rays, and the fan-shaped laser rays are perpendicular to the front side of the compass device box;

[0010] The front side of the chamber is provided with a first opening for the laser emitter to extend out;

[0012] Compared with the prior art, when measuring the inclination, the compass is placed upright on the measured surface, the angle of the inclination needle is adjusted to make the spirit level above it horizontal, and the inclination reading is read. However, this method has many limitations. First, the compass needs to be placed close to the measured surface. Second, when only one crack is exposed on the measured surface and no surface is exposed, it is difficult to ensure that the connected surface is consistent with the side surface by connecting a plane outside the crack, and the error is also large. Third, when the exposed surface of the measured surface is in a place that is difficult to touch due to environmental, height, safety and other factors, it is impossible to accurately measure the occurrence of the measured surface. The utility model provides a geological compass device for measuring the occurrence of high-distance cracks. The direction and inclination of the cracks can be obtained by fan-shaped laser rays. It can provide accurate occurrence of the measured surface, ensure the safety of engineers, and provide scientific and safe scientific data for geological exploration.

When coincident, the line can pass through the fracture smoothly, that is, the surface of the fan-shaped laser line is consistent with the fracture surface. At this time, the occurrence of the fracture surface can be reflected on the surface formed by the fan-shaped laser line. In the process of adjusting the compass to make the fan-shaped laser line consistent with the fracture surface, the compass is always kept horizontal, so the angle of the laser emitter is the angle between the surface of the fan-shaped laser line and the horizontal plane, and the compass and the laser line are close to each other, so the compass and the fracture surface are also close to each other and located in the inclination direction. Then the angle between the laser line and the horizontal plane can reflect the inclination angle.

In this solution, the entire worm can be driven to rotate by manually rotating the extended part of the rotating wheel.

[0015] In a further solution, the outer side of the rotating wheel is provided with anti-skid teeth.

However, this method has many limitations. First, the compass needs to be placed close to the measured surface. Second, when only one crack is exposed on the measured surface and no surface is exposed, it is difficult to ensure that the connected surface is consistent with the side surface by connecting a plane outside the crack, and the error is also large. Third, when the exposed surface of the measured surface is in a place that is difficult to touch due to environmental, height, safety and other factors, it is impossible to accurately measure the occurrence of the measured surface. The utility model provides a geological compass device for measuring the occurrence of high-distance cracks. The direction and inclination of the crack can be obtained by fan-shaped laser rays.

Since the fan-shaped laser rays emitted by the laser emitter 2 are perpendicular to the surface of the compass device box 1, and the emission starting point of the laser emitter 2 is preferably coplanar with the front side of the compass device box 1; in this way, in actual operation, In the process, first ensure that the compass is level, and then drive the laser emitter 2 to rotate so that the fan-shaped laser line coincides with the crack on the rock mass. When they coincide, the line can pass through the crack smoothly, that is, the surface of the fan-shaped laser line is consistent with the crack surface. At this time, the occurrence of the crack surface can be reflected on the surface formed by the fan-shaped laser line; in the process of adjusting the compass to make the fan-shaped laser line consistent with the crack surface, the compass always remains horizontal, so the angle of the laser emitter 2 is the angle between the surface of the fan-shaped laser line and the horizontal plane, and the compass and the laser line are close to each other, so the compass and the crack surface are also close to each other and located in the inclination direction, then the angle between the laser line and the horizontal plane can reflect the inclination angle; the angle between the surface formed by the fan-shaped laser line and the horizontal plane is also the inclination angle of the crack surface.

This solution is implemented by the transmission mode of the worm wheel 5.

[0039] In this embodiment, in order to facilitate the rotation of the worm 5, a rotating wheel 6 is sleeved on the worm 5, and the front side of the chamber has a second outlet for the extending rotating wheel 6. In this solution, the worm 5 can be driven to rotate as a whole by manually rotating the extending part of the rotating wheel 6.

[0040] In this embodiment, the outer side of the rotating wheel 6 is provided with anti-skid teeth.

[0041] In this embodiment, in order to facilitate the rapid measurement of the inclination angle, a sleeve 7 is also sleeved on the worm 5, and the sleeve 7 has a scale on the outer side of the circumference; the front side of the chamber has a display frame 8 for displaying the scale; the rotation gear ratio of the sleeve 7 and the rotating wheel 6 is 1:1. In this scheme, since the sleeve 7 is sleeved on the worm 5, when the rotating wheel 6 is rotated, the sleeve 7 is driven to rotate synchronously, and the corresponding rotation scale can be read. Then, through the gear ratio between the worm gear 5 and the eccentric position of the laser emitter 2, the rotation angle of the laser emitter 2 can be calculated through the corresponding rotation scale, so as to obtain the angle between the surface formed by the fan-shaped laser beam and the horizontal plane; wherein the diameter ratio between the rotating wheel 6 and the laser emitter 2 can be preferably 1:30, so that the adjustment angle of the laser emitter 2 is more accurate, and at the same time, the laser emitter 2 is protected from being damaged due to excessive rotation angle.

When coincident, the line can pass through the crack smoothly, that is, the surface of the fan-shaped laser line is consistent with the surface of the crack. At this time The occurrence of the crack surface can be reflected on the surface formed by the fan-shaped laser lines; in the process of adjusting the compass to make the fan-shaped laser lines consistent with the crack surface, the compass is always kept horizontal, so the angle of the laser emitter 2 is the angle between the surface of the fan-shaped laser lines and the horizontal plane, and the compass and the laser lines are close to each other, so the compass and the crack surface are also close to each other and located in the inclination direction, so the angle between the laser line and the horizontal plane can reflect the inclination angle; by measuring the angle between the surface formed by the fan-shaped laser lines and the horizontal plane, it is also the inclination angle of the crack surface.
