Description

Technical Field

[0001] The invention relates to analysis and measurement control technology, and in particular to a simple geological disaster crack deformation monitoring instrument. Background Art

[0002] In the current field of geological disaster monitoring, crack monitoring of buildings and some structures often uses patch method, nail embedding method and installation of rope displacement meter to monitor cracks. The principle is to anchor two points on both sides of the crack, and use the displacement of the patch, the change in the spacing between the nails and the change in the length of the rope of the rope displacement meter as the carrier to reflect the relative displacement of the two points, that is, the change of the crack, so as to monitor the crack.

[0003] When using an existing simple monitoring instrument for the deformation of geological disaster cracks, the above three monitoring methods all have their own shortcomings in actual work. Taking the strong cracks that are most involved in actual work as an example, the patch method is only suitable for the situation where the walls on both sides of the crack are flat, the deformation direction is single, and the displacement is not complicated. If the walls on both sides of the crack are not on the same imaginary plane, the monitoring patches fixed on the walls on both sides of the crack cannot be effectively combined, which greatly reduces the detection effect. In addition, the patch method can only monitor the displacement on a single axis intuitively and accurately; the buried nail method and the pull-rope displacement meter can only monitor the comprehensive displacement of the walls on both sides of the crack, and they are not intuitive. The buried nail method has the shortcomings of poor reliability of monitoring data, high cost of the pull-rope displacement meter, and high maintenance cost. At the same time, these three are not intuitive in the embodiment and recording of the entire monitoring data. Summary of the invention

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Embodiment 1:

[0040] See also Figure 1 , Figure 2 , Figure 6 as well as Figure 8 , a simple geological disaster crack deformation monitoring instrument, including:

[0041] Recording board 1, one side of which is printed with a checkered paint surface, used for recording marks;

[0042] A fixing plate 6, which is installed on the wall to be tested;

[0043] A limit frame 4, which is fixedly mounted on the top of a fixed plate 6;

[0044] A rotating shaft 3, which is rotatably mounted on the inner wall of a limiting frame 4;

[0045] A rotating rod 5, which is sleeved on the outer side of the rotating shaft 3;

[0046] A trace-leaving rod 2, which is fixedly mounted on a side of a rotating rod 5 away from a limiting frame 4;

[0047] The torsion spring 7 is fixedly connected to the inner wall of the limit frame 4 and the inner wall of the rotating rod 5, and is used to provide a restoring force for the rotating rod 5.

[0048] The specific implementation method is that the recording board 1 is a 10cm×10cm square plastic board with adhesive backing. Four holes with a diameter of 0.35cm are opened at the four corners of the plastic board to facilitate the use of nails to fix the part on the object to be detected. The main body of the recording board 1 is a hard plastic board, and one side of the plastic board is a primer to facilitate the fixing of the plastic board on the wall. The other side is a lacquered smooth surface printed with a checkered pattern, which is used to record the crack deformation trajectory. A dial is installed on one side of the limit frame 4, which is used to record the rotation angle of the rotating rod 5.

[0049] Embodiment 2:

[0050] See also Figure 1 , Figure 2 , Figure 6 as well as Figure 8 This embodiment provides an implementation method based on the first embodiment. When in use, the recording plate 1 and the fixed plate 6 are respectively fixed on both sides of the crack to be monitored, and the mark rod 2 is within the checkered paint surface of the recording plate 1, and the torsion spring 7 is used to apply a carving force to the mark rod 2. If the crack changes, the mark rod 2 fixed on one side of the crack will scratch the checkered paint surface of the recording plate 1, thereby intuitively recording the deformation of the crack. At the same time, the deformation of the crack in the X and Y axes can be obtained through the checkered pattern. The change of the crack in the Z axis can be seen through the change of the angle between the scale on the limit frame 4 and the rotating rod 5, thereby intuitively, accurately, and multi-angle monitoring of the crack deformation.

[0051] Embodiment three:

[0052] See also Figure 3 - Figure 5 as well as Figure 7 This embodiment provides an implementation method based on the first embodiment, and further includes:

[0053] Recording board 2 11, one side of which is printed with a checkered paint surface, used for recording traces;

[0054] A second fixing plate 18, which is mounted on the wall;

[0055] The second limiting frame 17 is fixedly mounted on the top of the second fixing plate 18;

[0056] A third rotating shaft 16, which is rotatably mounted on the inner wall of the second limiting frame 17;

[0057] A rotating rod 3 15, which is sleeved on the outer side of the rotating shaft 3 16;

[0058] The second torsion spring 19 is fixedly mounted on the inner wall of the second limiting frame 17 and the inner wall of the third rotating rod 15;

[0059] The second rotating shaft 14 penetrates the third rotating rod 15 and is rotatably connected to the inner wall of the third rotating rod 15;

[0060] The second rotating rod 13 is sleeved on the outer side of the second rotating shaft 14 and is rotatably connected to the inner wall of the third rotating rod 15;

[0061] The second trace-leaving rod 12 is fixedly mounted on a side of the second rotating rod 13 away from the third rotating rod 15 .

[0062] The specific implementation is that the recording board 11 is a 10cm×10cm square rubber board with adhesive backing. There are four holes with a diameter of 0.35cm at the four corners of the rubber board to facilitate the use of nails to fix this part on the object to be detected. The main body of the recording board 11 is a hard rubber board, and one side of the rubber board is a primer to facilitate the fixing of the rubber board on the wall. The other side is printed with a checkered paint surface for recording the deformation trajectory of the crack. A dial is installed on one side of the limit frame 17 for recording the rotation angle of the rotating rod 3 15, and the rotating rod 13 can rotate with the axis of the rotating shaft 14 as the center of the circle, so that the device can monitor two walls that are not in the same plane.

[0063] Embodiment 4:

[0064] See also Figure 3 - Figure 5 as well as Figure 7This embodiment provides an implementation method based on the first embodiment. When in use, the recording plate 11 is installed on one wall, the device is installed on another wall, and the rotating rod 13 is rotated through the rotating shaft 14, so that the marking rod 12 can be tightly abutted against the recording plate 11. If the crack changes, the marking rod 12 leaves a mark on the recording plate 11 to record the deformation trajectory of the crack. A dial is installed on one side of the limit frame 17 to record the rotation angle of the rotating rod 3 15.

[0065] Working principle:

[0066] When in use, clearly define the location, type and range of cracks that need to be monitored, determine the purpose of monitoring, such as evaluating the impact of cracks on structural safety, monitoring the development trend of cracks, etc., install the device on the cracks and fix it on both sides of the cracks that need to be monitored to ensure that the instrument can accurately capture changes in the cracks. The two parts of the device fit tightly together. When the cracks change, the changes in the cracks can be reflected on the device, which is convenient for staff to record data later. The collected data will be stored in a designated database or file for subsequent analysis and processing to ensure the integrity and accuracy of the data and avoid data loss or damage. Statistical analysis, time series analysis and other methods are used to analyze the changing trends and laws of cracks, calculate indicators such as the width change rate and depth change rate of cracks, and evaluate the development speed of cracks. According to the changes in cracks and structural safety standards, the impact of cracks on structural safety is evaluated. If the cracks develop rapidly or reach the warning value, an alarm should be issued in time and corresponding measures should be taken.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
