Description

Technical Field

[0001] The utility model relates to the technical field of geological disaster deep displacement monitoring, in particular to a geological disaster deep displacement monitoring device. Background Art

[0002] When conducting geological disaster early warning, it is often necessary to use a drill bit to drill a measuring hole in the stratum and monitor the displacement of the hole wall of the measuring hole to determine the overall displacement of the bottom layer in the current area. When monitoring the displacement of the hole wall, a geological disaster deep displacement monitoring device is needed. For example, according to the search report of the novelty search agency, application number: 202321836115.5 discloses a geological disaster deep displacement monitoring device, comprising: an inclinometer tube with a cavity therein; and a plurality of groups of measuring components arranged at intervals inside the inclinometer tube, the measuring components comprising: scale lines and a gyroscope arranged on the inner wall of the inclinometer tube, an upper probe and a lower probe located at the lower end of the gyroscope and suspended in the inclinometer tube, and a motor arranged at the upper probe and whose output shaft is connected to the lower probe shaft, and a control module electrically connected to the gyroscope and a measuring module electrically connected to the control module are provided in the lower probe. The distance module, acquisition module, data transmission module, power supply module and control module respectively obtain angle information, distance information between the lower part of the probe and the inner wall of the inclinometer tube, and scale line information relative to the lower part of the probe. After analysis, the information is sent to the data receiving end via the data transmission module. During monitoring, the control module controls the rotation of the motor, uses the distance measurement module to measure the distance information between the lower part of the probe and the inner wall of the inclinometer tube, and captures the scale line information relative to the lower part of the probe in real time. Based on the above information, the scale line information relative to the lower part of the probe when the distance between the lower part of the probe and the inner wall of the inclinometer tube is the shortest is screened out, and is sent to the data receiving end together with the angle information of the gyroscope via the signal transmission module. In this way, the scale line information corresponding to the lower part of the probe can be accurately obtained, and the horizontal displacement of the soil calculated thereby is more accurate. The device can correctly read the scale line data and obtain the accurate horizontal displacement of the measured soil.

[0003] The geological disaster deep displacement monitoring device disclosed in the above patent can obtain the accurate horizontal displacement of the measured soil through the cooperation of the measuring component, control module, distance measuring module, acquisition module, data transmission module and power supply module. However, it still has the following shortcomings during use: the distance measuring module, acquisition module, data transmission module and power supply module are all installed on one side of the lower part of the probe. During measurement, the control module drives the motor to rotate and drives the lower part of the probe and the multiple modules thereon to rotate in a circle. The circular rotation changes the direction angle to measure the distance around the inner wall of the measuring tube. The shortest distance is screened out from the measured distance data to calculate the distance. The horizontal displacement of the soil, whose direction of the shortest distance is the direction of the inclination of the inclinometer tube, is screened by measuring the distance of a circle. The calculation is large and the motor is required to continuously drive the lower part of the probe and the module on it to rotate, and measure during the rotation process. The lower part of the probe will shake during the continuous rotation, thereby affecting the distance between the distance measuring module and the inner wall of the inclinometer tube, and thus affecting the measurement accuracy. In general, it is not possible to control the motor to drive the distance measuring module to rotate directly to the direction of the inclinometer tube's inclination to perform static distance measurement after the inclinometer tube tilts. In view of the above situation, the present application proposes a deep displacement monitoring device for geological disasters. Utility Model Content

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown:

[0028] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "Application No. 202321836115.5 discloses a geological disaster deep displacement monitoring device, wherein the distance measuring module, the acquisition module, the data transmission module and the power supply module are all installed on one side of the lower part of the probe. During measurement, the motor is driven by the control module to rotate and drive the lower part of the probe and the multiple modules thereon to rotate in a circular manner. The circumferential distance of the inner wall of the measuring tube is measured by changing the direction angle through the circumferential rotation. The shortest distance is screened out from the measured circumferential distance data to calculate the horizontal displacement of the soil. The direction position of the shortest distance is the inclinometer. The method of screening the shortest distance by measuring the distance around the tube in the direction of inclination requires a large amount of calculation and requires a motor to continuously drive the lower part of the probe and the module on it to rotate. Measurement is performed during the rotation process. The lower part of the probe will shake during the continuous rotation, thereby affecting the distance between the distance measurement module and the inner wall of the inclinometer tube, thereby affecting the measurement accuracy. In general, it is not possible to control the motor to drive the distance measurement module to rotate directly in the direction of the inclinometer tube's inclination to perform static distance measurement after the inclinometer tube tilts. In terms of use, this problem is obviously a real problem that is difficult to solve. The electrical equipment involved in this product is all powered by an external power supply.

[0029] More specifically:

The top of the cover plate 101 and the outside of the inclinometer casing 1 are installed with a tilt monitoring control mechanism 3 for monitoring the tilt of the inclinometer casing 1. The tilt monitoring control mechanism 3 is electrically connected to multiple motors.

[0031] The tilt monitoring control mechanism 3 includes a universal rotating extrusion assembly threadedly fixed to the outside of the inclinometer tube 1, and a mounting seat 303 is movably sleeved on the universal rotating extrusion assembly. The universal rotating extrusion assembly includes a mounting tube 305 threadedly fixed to the outside of the inclinometer tube 1, wherein both sides of the inclinometer tube 1 are provided with bolt grooves, and T-shaped fixing bolts are threadedly sleeved in the bolt grooves. The mounting tube 305 is threadedly sleeved on the two T-shaped fixing bolts, and the fixed connection between the mounting tube 305 and the inclinometer tube 1 is achieved by the two T-shaped fixing bolts. The bottom end of the mounting tube 305 is fixedly connected to a universal ball 304, and the universal ball 304 is movably sleeved on the inclinometer tube 1, wherein the top of the universal ball 304 is provided with a movable through-hole, and the inner wall of the movable through-hole is in contact with the inclinometer tube 1. The outer side of the inclinometer tube 1 is in movable contact. After use, the inclinometer tube 1 can be separated from the mounting tube 305 and the universal ball 304 by loosening the T-shaped fixing bolts, thereby improving the flexibility of use. The mounting seat 303 is movably mounted on the universal ball 304. A spherical groove is formed on the top of the mounting seat 303. The inner wall of the spherical groove is in movable contact with the outer side of the universal ball 304. To facilitate the installation of the universal ball 304, the mounting seat 303 can be welded from two mounting blocks. The arrangement of the universal ball 304 allows the inclinometer tube 1 to rotate and tilt in all directions. The outer side of the mounting tube 305 is annularly fixedly connected to a plurality of extrusion rods 309 located in the mounting sleeve 306. The end of the extrusion rod 309 away from the mounting tube 305 is embedded with an extrusion ball.

[0032] The outer fixing sleeve of the mounting seat 303 is provided with a fixing assembly, which includes a mounting plate 301 fixedly mounted on the mounting seat 303, two T-shaped anchor rods 302 are provided on both sides of the mounting seat 303, and the mounting plate 301 is threadedly mounted on the four T-shaped anchor rods 302, wherein anchor holes are opened on both sides of the top of the mounting plate 301, and the anchor holes are threadedly connected to the corresponding T-shaped anchor rods 302. The T-shaped anchor rods 302 are screwed into the soil to fix the mounting seat 303 and the mounting plate 301;

[0033] The top of the mounting seat 303 is fixedly connected with a mounting sleeve 306, and the mounting tube 305 is located in the mounting sleeve 306. The same elastic shielding cover 307 is bonded and fixed between the top of the mounting sleeve 306 and the outer side of the mounting tube 305. The elastic shielding cover 307 is used to shield the top of the mounting sleeve 306 to prevent soil from entering the mounting sleeve 306. Multiple groups of displacement monitoring components are installed in the mounting sleeve 306. The displacement monitoring components include a moving block 310 arranged in the mounting sleeve 306. The multiple moving blocks 310 are arranged in a ring shape, and multiple extrusion rods 309 are located between the multiple moving blocks 310. The extrusion ball is in movably contact with the side of the corresponding moving block 310 close to the mounting tube 305. The extrusion ball and the corresponding extrusion rod 309 cooperate to extrude and drive the moving block 310, and the moving block 310 is away from the mounting A T-shaped guide rod 311 is fixedly connected to one side of the tube 305, and the mounting sleeve 306 is slidably sleeved on multiple T-shaped guide rods 311, wherein multiple guide holes are opened on the side wall of the mounting sleeve 306, and the interior of the guide holes is in sliding contact with the outer side of the corresponding T-shaped guide rod 311. The T-shaped guide rod 311 has a lateral guiding effect on the corresponding moving block 310, and multiple tension sensors 312 are embedded and fixed in a ring shape on the outer side of the mounting sleeve 306. A flexible spring 313 is fixedly connected between the detection end of the tension sensor 312 and the corresponding T-shaped guide rod 311. The tension sensor 312 is used to drive the extrusion force of the flexible spring 313. The elastic force of the flexible spring 313 is relatively small. Compared with the extrusion force of the displacement of the measured soil, its elastic force can directly offset the extrusion force. The flexible spring 313 is movably sleeved on the corresponding T-shaped guide rod 311;

[0034] The fixing sleeve on the mounting sleeve 306 is provided with a protective cover 308 with an opening at the bottom, and the bottom of the protective cover 308 is fixedly connected to the top of the mounting plate 301, and multiple T-shaped guide rods 311 and multiple flexible springs 313 are all located in the protective cover 308. The protective cover 308 is used to protect the multiple T-shaped guide rods 311 and multiple flexible springs 313 from being affected by the soil. The top of the cover 101 is fixedly connected to a control reminder component, which includes a PLC controller 314 fixedly connected to the top of the cover 101. The right side of the PLC controller 314 is fixed and electrically connected with a synchronous control switch 315 and an audible and visual alarm 316. The PLC controller 314 is electrically connected to multiple tension sensors 312, and the synchronous control switch 315 is electrically connected to multiple motors. The synchronous control switch 315 cooperates with the PLC controller to control the synchronous start of multiple motors. The PLC controller 314 has a built-in coordinate system, and the angles and positions of the multiple tension sensors 312 are pre-determined in the coordinate system. The angular position of the tension sensor 312 is the angle of rotation of the motor output shaft. The setting of the angle and position of the tension sensor 312 are both directly set through actual measurement. The principle of the PLC controller 314 receiving the signal of the tension sensor 312 to control the motor is the existing technology, which is a basic programming setting CNC control method well known to those skilled in the art. It can be achieved by CNC programmers editing the corresponding control numerical program. They are all conventional means or common knowledge and will not be repeated here. The present invention, through the setting of a series of structures, can control the motor to drive the lower part of the probe to directly rotate to the inclination angle for distance measurement according to the inclination direction of the inclinometer tube 1 before measurement. This measurement method can directly measure the shortest distance without measuring the distance of a circle for screening, reducing the amount of calculation, and does not require the motor to drive the lower part of the probe to rotate continuously. It can be measured after stopping rotation, which can effectively reduce the shaking and offset caused by the continuous rotation of the lower part of the probe, thereby improving measurement accuracy.

[0035] Working principle: When in use, the entire device is placed in the measuring hole of the soil to be measured. After placement, the four T-shaped anchor rods 302 can be driven to rotate and screwed into the soil by means of an external extended rotation tool. The bite force between the T-shaped anchor rods 302 and the soil is used to fix the mounting plate 301, the mounting seat 303, the mounting sleeve 306 and the displacement monitoring component. After fixation, the entire device is pre-buried in the measuring hole, and the inner wall of the inclinometer tube 1 is in contact with the soil. The end of the inclinometer tube 1 is placed on the surface of the soil to be measured (such as Figure 6 As shown), since the elastic shielding cover 307 and the protective cover 308 cooperate with each other, the top and surrounding of the installation sleeve 306 can be protected, and the soil will not affect the components connected to the installation sleeve 306;

[0036] A coordinate system is pre-installed in the PLC controller 314. The angles and positions of the multiple tension sensors 312 are pre-determined in the coordinate system. The angle position of the tension sensor 312 is the angle of rotation of the motor output shaft. At the same time, each tension sensor 312 is numbered. For example, the angle of the tension sensor 312 No. 1 is 15 degrees, and the Z, Y, Z coordinate position is (3, 0, 0). When the measured soil does not undergo horizontal displacement, the inclinometer tube 1 remains in a vertical state. When the measured soil undergoes horizontal displacement, the mounting plate 301, the mounting seat 303, the mounting sleeve 306 and the displacement monitoring assembly are The inclinometer tube 1 is fixed and will not tilt, but it will tilt along with the horizontal displacement of the measured soil. When the inclinometer tube 1 tilts, it will drive the mounting tube 305 fixed thereto to rotate and tilt. The mounting tube 305 drives the universal ball 304 to rotate in the mounting seat 303. The mounting tube 305 also drives multiple extrusion rods 309 and multiple extrusion balls to rotate in the tilting direction. When the extrusion rods 309 in the tilting direction move, the corresponding extrusion balls squeeze the moving block 310. Under the squeezing force, the moving block 310 will move in the tilting direction of the inclinometer tube 1. The moving block 310 drives the corresponding extrusion balls to rotate in the tilting direction. The corresponding T-shaped guide rod 311 moves and stretches the flexible spring 313, and the flexible spring 313 generates tension on the tension sensor 312. At this time, when the tension sensor 312 detects the tension, it transmits the signal to the PLC controller 314. After receiving the signal, the PLC controller 314 controls multiple motors to start and rotate at the same angle synchronously through the synchronous control switch 315 according to the position angle of the received tension sensor 312. The motor can drive the corresponding lower part of the probe and the module on the lower part of the probe to rotate directly to the tilted direction and rotate to the required direction. After the angle is reached, the motor is controlled to turn off. At this time, the module on the lower part of the probe can measure the distance, thereby calculating the horizontal displacement of the soil. It monitors the inclination of the inclinometer tube 1 and controls the motor to start according to the inclination direction to drive the lower part of the probe to rotate directly to the inclination angle for distance measurement. This measurement method can directly measure the shortest distance without measuring the distance for a circle for screening, reducing the amount of calculation. It does not require the motor to drive the lower part of the probe to rotate continuously, and the method of measuring after stopping the rotation can effectively reduce the shaking and offset caused by the continuous rotation of the lower part of the probe, thereby improving the measurement accuracy.

[0037] The specific measurement and calculation principle of the module has been mentioned in patent application number 202321836115.5 and will not be elaborated here.

[0038] In addition, when the inclinometer tube 1 tilts, the PLC controller 314 also controls the sound and light alarm 316 to emit a sound and light alarm to remind personnel. After use, the entire device can be dug out from the measuring hole and wait for the next use.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
