Description

Technical Field

[0001] This application relates to the technical field of tilt angle monitoring devices, and in particular to a soil and rock tilt angle monitoring device. Background Technology

[0002] Currently, soil and rock tilt angle monitoring devices are specialized equipment used to monitor changes in the tilt of the ground or buildings. They are widely used in fields such as geological disaster early warning and building structural health monitoring. These devices can monitor the tilt of soil and rock masses in real time, promptly identify potential risks, and provide data support for taking preventive measures.

[0003] In related technologies, formation dip logging tools are specialized instruments used to determine the strike, dip, and dip angle of rock formations. They calculate the formation attitude by measuring the relative dip parameters of the rock formations and the wellbore trajectory data within the borehole. Currently, most formation dip logging tools used are four-arm type. Because measuring three or four points on the formation bedding plane is sufficient to determine its spatial location, using a four-arm formation dip logging tool allows for the determination of the spatial location of the measured bedding plane.

[0004] Formation dip logging tools are equipped with high-precision accelerometers and magnetometers. The accelerometer measures the instrument's tilt angle relative to the direction of gravity, while the magnetometer determines the instrument's azimuth. Combining these two sets of data allows for the calculation of the formation's dip and strike. The logging instrument typically communicates with the main unit via cable. Monitoring personnel use the cable to gradually place the instrument into the borehole. However, during cable placement, it's difficult to ensure the instrument descends along the designated path. If the monitoring personnel's hand position deviates, the instrument may collide with the borehole wall, interfering with data acquisition, affecting the accuracy of the monitoring data, and increasing the workload for subsequent data analysis.

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] This application discloses a device for monitoring the tilt angle of soil and rock.

[0018] Reference Figure 1 , Figure 2 The soil and rock tilt angle monitoring device includes a main unit 1 and a measuring instrument 2 for insertion into the borehole. The measuring instrument 2 is equipped with a high-precision accelerometer and magnetometer sensor. The accelerometer measures the tilt angle relative to the direction of gravity, while the magnetometer determines the azimuth. By combining these two sets of data, the dip angle and strike of the strata can be calculated. The data collected by the measuring instrument 2 is transmitted via cable to the main unit 1 on the ground, where it is processed and analyzed.

[0019] Host 1 may include a central processing unit such as a CPU or MPU, or a system built around a CPU or MPU, including hardware or software. Users can freely control these modules through programming, making them operate according to their wishes. Local data transfer / traceability components, remote data transfer / traceability components, and remote communication components can also be controlled through internal protocols. Internal protocols may include some or all of the following protocols: human-machine interface protocols, software / hardware (interface) protocols, chip bus (C-Bus) protocols, and internal bus (I-Bus) protocols. With the development of integrated circuit technology, some protocols that belong to external bus (E-Bus) have also been integrated into the chip and thus become internal protocols.

[0020] like Figure 1 , Figure 2 As shown, it also includes a mounting frame 3 and a base 6. A cable reel 4 is detachably mounted on the mounting frame 3, and a cable is wound and wound on the cable reel 4. The main unit 1 and the measuring instrument 2 establish a signal connection through the cable. The mounting frame 3 includes a platform 30 located at the top, and three diagonal support rods 31 arranged circumferentially at even intervals around the bottom of the platform 30. The upper ends of the diagonal support rods 31 are tightened and fixed to the platform 30 by fasteners (bolts and nuts), and the lower ends of the diagonal support rods 31 are supported on the base 6.

[0021] like Figure 1 , Figure 3 As shown, the bottom of the base 6 is threaded with three support legs 61, each corresponding to one of the diagonal braces 31. The central axis of each support leg 61 extends from the upper surface of the base 6, and the lower ends of the diagonal braces 31 are respectively inserted and limited at the top of their respective support legs 61. The upper surface of the base 6 is provided with multiple limiting springs 62, each corresponding to one of the diagonal braces 31. One end of each limiting spring 62 is suspended and fixed to the base 6, and the other end is suspended and fixed to its respective diagonal brace 31. The limiting springs 62 are used to press the diagonal braces 31 downwards against the top of the support legs 61, thereby further improving the stability of the mounting frame 3 and preventing it from tipping over on the base 6.

[0022] like Figure 1 As shown, three threaded posts 63 are fixedly installed on the base 6 in a circumferentially evenly spaced ring. The length of the threaded posts 63 extends along the height direction of the mounting frame 3. The bottom of the cable reel 4 is inserted and limited on the base 6 from top to bottom, and the bottom of the cable reel 4 is inserted outside one of the threaded posts 63. A fastening nut 64 is threadedly connected to the threaded post 63. The fastening nut 64 is used to tighten and fix the bottom of the cable reel 4 on the base 6.

[0023] like Figure 1 , Figure 2 As shown, a positioning hole 60 passes through the central axis of the base 6, and a suspension 7 located directly above the positioning hole 60 is threaded onto the platform 30. The length of the suspension 7 extends downward along the height of the mounting bracket 3. A fixed pulley 70 is rotatably installed at the bottom of the suspension 7, and a cable is wound around the fixed pulley 70. The measuring instrument 2 connected to the end of the cable is suspended on the suspension 7 through the cable.

[0024] When it is necessary to place the measuring instrument 2 inside the borehole, the cable is released from the cable reel 4 by rotating the cable reel 4. At this time, under the guidance of the fixed pulley 70, the measuring instrument 2 can be stably and accurately inserted into the borehole in the specified direction. Compared with manual cable laying, it can effectively reduce the impact of human interference on data acquisition, improve the accuracy of monitoring data, and simplify the data analysis process.

[0025] like Figure 2 , Figure 4 As shown, three adjusting rods 8, with a length consistent with the length of the suspension 7, are threaded onto the platform 30. These three adjusting rods 8 are evenly spaced circumferentially around the platform 30. A common adjusting platform 5 is rotatably mounted on the top of each of the three adjusting rods 8. A universal joint 80 is mounted on the top of each adjusting rod 8, and the adjusting platform 5 is detachably inserted and fixed to the universal joint 80 at the top of the adjusting rod 8. By manually rotating a turntable 81, which is coaxially fixed to the outside of the adjusting rod 8, the adjusting rod 8 rotates, causing it to rise and fall on the platform 30. Since the adjusting platform 5 is rotatably mounted on top of the adjusting rod 8 via the universal joint 80, adjusting the universal joints 80 at the top of the three adjusting rods 8 to the same horizontal plane ensures that the adjusting platform 5 remains horizontal.

[0026] like Figure 2 , Figure 4 As shown, three magnetic bases 32 arranged in a circumferentially evenly spaced ring are fixedly installed on the upper surface of the adjustment platform 5. Magnetic plates 10, corresponding one-to-one with the magnetic bases 32, are fixedly installed on the bottom of the main unit 1. The magnetic bases 32 are used to attract and fix the magnetic plates 10 to each other. The bottom of the main unit 1 also has multiple threaded holes 11, and the adjustment platform 5 has multiple through holes corresponding one-to-one with the threaded holes 11. Fastening bolts with threads connected to the threaded holes are inserted into the through holes. Through the mutual attraction between the magnetic bases 32 and the magnetic plates 10, the main unit 1 can be initially fixed on the adjustment platform 5. When further fixing of the main unit 1 is required, the fastening bolts are tightened from bottom to top into the threaded holes 11 at the bottom of the main unit 1, thereby stably and securely fixing the main unit 1 to the adjustment platform 5.

[0027] The implementation principle is as follows: When it is necessary to place the measuring instrument 2 in the borehole, the cable is released from the cable reel 4 by rotating the cable reel 4. At this time, under the guidance of the fixed pulley 70, the measuring instrument 2 can be stably and accurately inserted into the borehole in the specified direction. Compared with manual cable laying, it can effectively reduce the impact of human interference on data acquisition, improve the accuracy of monitoring data, and simplify the data analysis process.

[0028] By manually rotating the turntable, which is coaxially fixed outside the adjusting rod 8, the adjusting rod 8 can be rotated, causing it to rise and fall on the platform 30. By adjusting the tops of the three adjusting rods 8 to the same horizontal plane, the adjusting platform 5 can be kept level. The limiting spring 62 is used to press the diagonal brace 31 downward against the top of the support foot 61, thereby further improving the stability of the mounting frame 3 and making it less likely for the mounting frame 3 to tip over on the base 6.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
