Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and specifically to a borehole deviation surveying device for geological exploration. Background Art

[0002] The main purpose of borehole deviation surveying during geological exploration is to ensure the verticality and accuracy of the borehole, and avoid geological information errors caused by borehole deviation, so as not to affect subsequent engineering design and construction. If the borehole deviates, the collected data may be inaccurate, affecting the judgment of the underground structure. Therefore, during geological exploration operations, it is necessary to periodically lower a borehole inclinometer to the borehole measurement location to measure the deviation degree of the borehole.

[0003] During the drilling operation of geological exploration, in order to ensure the verticality and accuracy of the borehole and avoid geological information errors caused by borehole deviation, it is necessary to detect the inclination of the borehole at regular intervals. Generally, a columnar angle detector is lowered into the borehole to detect the borehole inclination. However, since the borehole diameters are different, larger borehole diameters require larger-sized detector probes to ensure the accuracy and stability of the measurement. When measuring boreholes with different diameters, it is often necessary to replace the probes with different diameters multiple times, which is rather inconvenient.

[0004] In the patent document with the publication number CN117514145B, a logging-while-drilling (LWD) inclination tool is disclosed. This device can enter the working state only when needed, with extremely low tool wear and power consumption, greatly improving the overall endurance. However, this device is difficult to adapt to the inclination detection of inclined boreholes. Since vertical boreholes and inclined boreholes are generally used in two exploration and drilling methods during geological exploration, the inclination measurement method for vertical boreholes is generally to detect whether there is an angular change between the borehole axis and the geocentric vertical line. When conducting exploration and drilling for inclined boreholes, if the borehole axis rotates angularly with the geocentric vertical line as the center, this will result in no change in the included angle between the borehole axis and the geocentric vertical line, while in fact, the borehole azimuth has deviated from the original borehole angle.

[0005] In addition, currently, after the borehole inclination detector for geological exploration measures the borehole angle, it is still necessary to compare the measured angle data with the angle data of the original borehole to analyze whether the angle has deviated, making it difficult for the staff to quickly and intuitively confirm whether the measurement area deviates from the initial angle. Therefore, we propose a borehole deviation surveying device for geological exploration to solve the above problems. Summary of the Invention

[0006] The object of the present invention is to make up for the deficiencies of the prior art and propose a borehole deviation detection device for geological exploration. This device can adapt to the inclination detection of inclined boreholes, and at the same time can quickly and intuitively confirm whether there is a deviation between the measurement area and the initial angle. In addition, this device can adapt to boreholes of different diameters.

[0007] To solve the above technical problems, the present invention provides the following technical solution: A borehole deviation detection device for geological exploration, including a main cylinder. Inside the main cylinder, there are three clamping mechanisms arranged in a circumferential array. Each of the three clamping mechanisms includes a clamping plate, which controls the synchronous movement of the three clamping plates to clamp the borehole wall, so that the central axis of the main cylinder coincides with the central axis of the borehole.

[0008] Above the main cylinder, there is a storage cylinder fixed. Above the storage cylinder, there is a sealing shell arranged. Inside the sealing shell, there is a vertical detection mechanism. The vertical detection mechanism includes a counterweight ball. At the bottom of the counterweight ball, there is a positioning hole. At the inner top wall of the positioning hole, there is a double-hole wire harness receiver installed. Under the action of gravity, the counterweight ball rotates freely. After the counterweight ball stops, the central axis of the counterweight ball coincides with the geocentric vertical line. Inside the sealing shell, there is also a locking mechanism, which is used to limit and fix the counterweight ball.

[0009] Inside the storage cylinder, there is a positioning mechanism. The positioning mechanism includes a fixed column. Inside the inner wall of the fixed column, there is a sliding rod slidingly connected. At the top of the sliding rod, there is a positioning tube fixed. Inside the positioning tube, there is a wire harness transmitter installed. The positioning tube is adapted to the positioning hole. Inside the storage cylinder, there is also a limiting mechanism, which is used to limit and fix the fixed column.

[0010] Specifically, inside the main cylinder, there is a straight sleeve. The central axis of the straight sleeve coincides with the central axis of the main cylinder. The straight sleeve is fixed to the storage cylinder. Inside the inner wall of the straight sleeve, there is an electric push rod I fixed. The telescopic end of the electric push rod I is fixed with a support frame. On the outer surface of the sealing shell, there are two sliding plates fixed. Both of the two sliding plates are slidingly connected to the storage cylinder. Both of the two sliding plates are fixed to the support frame. On the outer surface of the sealing shell, there is a cover plate fixed. Above the cover plate, there is a throwing rope installed.

[0011] By adopting the above technical solution, controlling the electric push rod I to drive the support frame to move, the support frame can drive the sealing shell to move, so that the sealing shell seals the opening of the storage cylinder, preventing the internal parts of the storage cylinder from being impacted by external falling gravel during the inclination test. Through the setting of the pulley group, it is convenient for this device to slide in the borehole.

[0012] A motor one is fixed to the inner wall of the above-mentioned straight sleeve. The output end of the motor one is fixed with a unidirectional threaded rod. A threaded tube is threadedly connected to the outer surface of the unidirectional threaded rod. The clamping mechanism further includes a moving plate and two hinge rods. One end of each of the two hinge rods is hinged to the threaded tube, and the other end of each of the two hinge rods is hinged to the moving plate. A sliding frame is fixed to the outer surface of the straight sleeve, and the sliding frame is slidably connected to the moving plate. A plurality of connecting columns are fixed between the moving plate and the clamping plate, and all the connecting columns are slidably connected to the main cylinder.

[0013] By adopting the above technical solution, when the device is put into the drill hole, the device can slide in the drill hole through the pulley block. When the inclination detection is carried out, the driving motor one drives the unidirectional threaded rod to rotate. The rotation of the unidirectional threaded rod drives the threaded tube to move. When the threaded tube moves, the clamping plate on the moving plate is driven by the hinge rod to approach the drill hole wall, so that the three clamping plates move synchronously and clamp the drill hole wall, making the central axis of the main cylinder coincide with the central axis of the drill hole, so that the device can adapt to drill holes of different diameters.

[0014] Further, the vertical detection mechanism further includes an annular seat, a rotating ring and a rotating plate. The annular seat is fixed to the plugging shell. Two second rotating rods are fixed to the outer surface of the rotating ring, and both of the two second rotating rods are rotatably connected to the annular seat. Two second scale rings are fixed to the outer surface of the annular seat. Two groups of pointer blocks are fixed to the outer surface of the rotating ring, and the number of each group of pointer blocks is two. The two groups of pointer blocks are respectively adapted to the two second scale rings.

[0015] Two first rotating rods are fixed to the outer surface of the rotating plate. Both of the two first rotating rods penetrate through the rotating ring and are rotatably connected to the rotating ring. Anti-slip rings are fixed to the mutually remote ends of the two first rotating rods. A pointer column is fixed to the upper surface of the rotating plate. A first scale ring is fixed to the outer surface of the rotating ring, and the pointer column is adapted to the first scale ring. A detection head is installed on the inner wall of the plugging shell.

[0016] By adopting the above technical solution, the counterweight ball rotates freely under the action of gravity. After the counterweight ball stops, the central axis of the counterweight ball coincides with the geocentric vertical line. If the drill hole is inclined, by recording the angle change of the pointer column on the first scale ring and the angle change of the pointer block on the second scale ring through the detection head, the offset inclination of the drill hole here can be calculated.

[0017] Further, the locking mechanism includes a bidirectional threaded rod. One end of the bidirectional threaded rod penetrates through the plugging shell and is rotatably connected to the plugging shell. Two clamping half rings are threadedly connected to the outer surface of the bidirectional threaded rod. The two clamping half rings are respectively located on both sides of the anti-slip ring. Two first limiting rods are fixed to the inner wall of the plugging shell, and both of the two first limiting rods are slidably connected to the clamping half rings.

[0018] By adopting the above technical solution, after the counterweight ball stops, the central axis of the counterweight ball coincides with the geocentric vertical line. Rotate the bidirectional threaded rod to drive the two clamping half-rings to approach each other, and the two clamping half-rings clamp and fix the anti-slip ring, thereby limiting and fixing the counterweight ball in a vertical state.

[0019] Further, the positioning mechanism further includes a fixed ring rail, a pressure-receiving disc and a moving cylinder. Both of the two sliding plates are fixed to the fixed ring rail. The pressure-receiving disc is located at the bottom of the fixed ring rail. Two sliders are fixed to the outer surface of the pressure-receiving disc, and both of the two sliders are slidably connected to the fixed ring rail. Two limiting plates are fixed to the outer surface of the moving cylinder, and both of the two limiting plates are slidably connected to the pressure-receiving disc. The top end of the moving cylinder is fixedly communicated with a spherical sleeve. A universal ball is rotatably connected to the inner wall of the spherical sleeve, and the universal ball is fixed to the fixed column. A first telescopic spring is fixed to the bottom surface of the positioning tube, and a baffle is fixed to the outer surface of the fixed column. The two ends of the first telescopic spring are respectively fixed to the baffle and the positioning tube.

[0020] By adopting the above technical solution, when measuring and marking the original inclination of the drill hole, first limit and fix the counterweight ball in a vertical state, then freely move the fixed column, and quickly position the fixed column by inserting the positioning tube into the positioning hole. At this time, the wire harness transmitter can be sensed by the double-hole wire harness receiver. Since the central axis of the fixed column coincides with the central axis of the counterweight ball at this time, that is, the central axis of the fixed column coincides with the geocentric vertical line.

[0021] A pressing column is slidably connected to the inner wall of the above-mentioned moving cylinder. The top end of the pressing column is provided with anti-slip lines. Two pressing plates are fixed to the outer surface of the pressing column, and both of the two pressing plates are slidably connected to the moving cylinder. Two anti-slip edge strips are fixed to the upper surface of the pressure-receiving disc, and the two anti-slip edge strips correspond to the two pressing plates respectively. Two second telescopic springs are fixed to the upper surfaces of the two pressing plates, and both of the two second telescopic springs are fixed to the moving cylinder.

[0022] Further, linkage mechanisms are arranged outside both of the two sliders. The linkage mechanism includes a pressing block and a slide rail. The slide rail is fixed to the slider. A braking block is slidably connected to the inner wall of the slide rail, and the braking block is slidably connected to the slider. An extrusion rod is fixed to the outer surface of the braking block. An inclined chute adapted to the extrusion rod is formed on the outer surface of the pressing block, and the extrusion rod is slidably connected to the inner wall of the inclined chute. A square rod is fixed to the upper surface of the pressing block, and a fixed seat is fixed to the upper surface of the slider. The square rod is slidably connected to the fixed seat. A third telescopic spring is sleeved on the outer surface of the square rod, and the two ends of the third telescopic spring are respectively fixed to the fixed seat and the pressing block.

[0023] Furthermore, the limiting mechanism includes a moving frame and a transmission circular plate. Limiting rods II are fixed to the outer surfaces of the two sliding plates, and both limiting rods II are slidably connected to the moving frame. The moving frame is rotatably connected to the transmission circular plate. An electric push rod II is fixed to the bottom surface of the plugging shell, and the telescopic end of the electric push rod II is fixed to the moving frame. A toothed ring is fixed to the outer surface of the transmission circular plate, and a motor II is fixed below the moving frame. A gear is fixed to the output end of the motor II, and the gear meshes with the toothed ring.

[0024] By adopting the above technical solution, when the main cylinder slides in the drill hole, the device may rotate as a whole in the drill hole. In order to prevent the device from rotating as a whole and causing the position of the fixed column to shift, resulting in the dislocation of the fixed column and the counterweight ball, the drive motor II drives the transmission circular plate to rotate. Since the transmission circular plate presses the pressure plate, the transmission circular plate and the pressure plate are frictionally connected in transmission. Thus, the rotation of the transmission circular plate drives the pressure plate to rotate, and the rotation of the pressure plate drives the fixed column to rotate around the central axis of the main cylinder, thereby avoiding the dislocation of the fixed column and the counterweight ball.

[0025] Compared with the prior art, the drilling and inclination detecting device for geological exploration has the following beneficial effects:

[0026] First, through the arrangement of the vertical detection mechanism and the positioning mechanism, when measuring the original inclination angle of the drill hole, the counterweight ball rotates freely under the action of gravity. After the counterweight ball stops, the central axis of the counterweight ball coincides with the geocentric vertical line. The vertically placed counterweight ball is limited and fixed, and the position of the fixed column is freely moved until the wire harness emitted by the wire harness emitter can be sensed by the double-hole wire harness receiver. Then, the fixed column is limited and fixed. At this time, the central axis of the fixed column coincides with the geocentric vertical line. Then, the device is placed in the detection area. If the drill hole in the detection area is offset, the main cylinder follows the offset, making the central axis of the fixed column unable to coincide with the central axis of the counterweight ball. At this time, the double-hole wire harness receiver cannot receive the ray of the wire harness emitter. Through the information feedback of the double-hole wire harness receiver, the staff can directly confirm whether there is an inclination. The device can adapt to the inclination detection of inclined drill holes and can quickly and intuitively confirm whether there is a deviation between the measurement area and the initial angle.

[0027] Second, through the arrangement of the pulley group and the clamping mechanism, when the device is placed into the drill hole, the device can slide in the drill hole through the pulley group. When performing the inclination detection, the drive motor I drives the one-way threaded rod to rotate. The rotation of the one-way threaded rod drives the threaded tube to move. When the threaded tube moves, the clamping plates on the moving plate are driven by the hinge rods to approach the drill hole wall, so that the three clamping plates move synchronously and clamp the drill hole wall, making the central axis of the main cylinder coincide with the central axis of the drill hole, thereby enabling the device to adapt to drill holes with different diameters.

[0028] Other advantages, objects and features of the present invention will be set forth in part in the following description, and in part will be obvious to those skilled in the art based on the examination of the following, or can be taught from the practice of the present invention.

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] Please refer toFigures 1 to 15 , the present invention provides the following implementation schemes: A borehole inclination detection device for geological exploration, including a main cylinder 1. Inside the main cylinder 1, three clamping mechanisms 9 arranged in a circumferential array are provided. All three clamping mechanisms 9 include clamping plates 904, which control the synchronous movement of the three clamping plates 904 to clamp the borehole wall, so that the central axis of the main cylinder 1 coincides with the central axis of the borehole.

[0055] Above the main cylinder 1, a storage cylinder 2 is fixed. Above the storage cylinder 2, a sealing shell 3 is provided. Inside the sealing shell 3, a vertical detection mechanism 4 is arranged. The vertical detection mechanism 4 includes a counterweight ball 404. A positioning hole 413 is opened at the bottom of the counterweight ball 404. A double-hole wire harness receiver 405 is installed on the inner top wall of the positioning hole 413. The counterweight ball 404 rotates freely under the action of gravity. After the counterweight ball 404 stops, the central axis of the counterweight ball 404 coincides with the geocentric vertical line. A locking mechanism 5 is also arranged inside the sealing shell 3, and the locking mechanism 5 is used to limit and fix the counterweight ball 404.

[0056] Please refer specifically to Figure 1 , Figure 2 and Figure 3 , three pulley groups 19 are installed on the outer surface of the main cylinder 1. Inside the main cylinder 1, a straight sleeve 12 is arranged. The central axis of the straight sleeve 12 coincides with the central axis of the main cylinder 1. The straight sleeve 12 is fixed to the storage cylinder 2. An electric push rod 13 is fixed to the inner wall of the straight sleeve 12. The telescopic end of the electric push rod 13 is fixed with a support frame 11. Two sliding plates 10 are fixed to the outer surface of the sealing shell 3. Both sliding plates 10 are slidably connected to the storage cylinder 2. Both sliding plates 10 are fixed to the support frame 11. A cover plate 17 is fixed to the outer surface of the sealing shell 3. A throwing rope is installed above the cover plate 17.

[0057] Control the electric push rod 13 to drive the support frame 11 to move. The support frame 11 can drive the sealing shell 3 to move, so that the sealing shell 3 seals the opening of the storage cylinder 2, preventing the internal parts of the storage cylinder 2 from being impacted by external falling gravel during the inclination test. Through the setting of the pulley groups 19, it is convenient for the device to slide in the borehole.

[0058] An electric motor 14 is fixed to the inner wall of the straight sleeve 12. The output end of the electric motor 14 is fixed with a unidirectional threaded rod 15. A threaded tube 16 is threadedly connected to the outer surface of the unidirectional threaded rod 15. The clamping mechanism 9 further includes a moving plate 901 and two hinge rods 905. One end of each of the two hinge rods 905 is hinged to the threaded tube 16, and the other end of each of the two hinge rods 905 is hinged to the moving plate 901. A sliding frame 902 is fixed to the outer surface of the straight sleeve 12. The sliding frame 902 is slidably connected to the moving plate 901. A plurality of connecting columns 903 are fixed between the moving plate 901 and the clamping plate 904. All the plurality of connecting columns 903 are slidably connected to the main cylinder 1.

[0059] When the device is placed into the borehole, the pulley block 19 enables the device to slide in the borehole. When performing the inclination detection, the driving motor 1 drives the unidirectional threaded rod 15 to rotate. The rotation of the unidirectional threaded rod 15 drives the movement of the threaded tube 16. When the threaded tube 16 moves, the clamping plates 904 on the moving plate 901 are driven by the hinge rod 905 to approach the borehole wall, causing the three clamping plates 904 to move synchronously and clamp the borehole wall, making the central axis of the main cylinder 1 coincide with the central axis of the borehole, so that the device can adapt to boreholes of different diameters.

[0060] Please refer specifically to Figure 11 、 Figure 12 and Figure 13 ,The vertical detection mechanism 4 further includes a ring seat 401, a rotating ring 402 and a rotating plate 403. The ring seat 401 is fixed to the sealing shell 3. Two second rotating rods 410 are fixed to the outer surface of the rotating ring 402. Both of the two second rotating rods 410 are rotatably connected to the ring seat 401. Two second scale rings 412 are fixed to the outer surface of the ring seat 401. Two groups of pointer blocks 411 are fixed to the outer surface of the rotating ring 402. The number of each group of pointer blocks 411 is two. The two groups of pointer blocks 411 are respectively adapted to the two second scale rings 412.

[0061] Two first rotating rods 407 are fixed to the outer surface of the rotating plate 403.

A detection head 18 is installed on the inner wall of the sealing shell 3.

[0062] The counterweight ball 404 rotates freely under the action of gravity. After the counterweight ball 404 comes to rest, the central axis of the counterweight ball 404 coincides with the geocentric vertical line. If the borehole is inclined, by recording the angular change of the pointer column 406 on the first scale ring 409 and the angular change of the pointer blocks 411 on the second scale ring 412 through the detection head 18, the offset inclination of the borehole here can be calculated.

[0063] Please refer specifically to Figure 11 and Figure 12, the locking mechanism 5 includes a bidirectional threaded rod 501. One end of the bidirectional threaded rod 501 penetrates through the plugging shell 3 and is rotatably connected to the plugging shell 3. Two clamping half-rings 502 are threadedly connected to the outer surface of the bidirectional threaded rod 501. The two clamping half-rings 502 are respectively located on both sides of the anti-slip ring 408. Two first limiting rods 503 are fixed to the inner wall of the plugging shell 3, and both of the two first limiting rods 503 are slidably connected to the clamping half-rings 502. After the counterweight ball 404 is stationary, the central axis of the counterweight ball 404 coincides with the geocentric vertical line. Rotating the bidirectional threaded rod 501 drives the two clamping half-rings 502 to approach each other, and the two clamping half-rings 502 clamp and fix the anti-slip ring 408, thereby limiting and fixing the counterweight ball 404 in a vertical state.

[0064] A positioning mechanism 6 is arranged inside the storage cylinder 2. The positioning mechanism 6 includes a fixed column 608. A sliding rod 611 is slidably connected to the inner wall of the fixed column 608. A positioning tube 609 is fixed to the top end of the sliding rod 611. A wire harness transmitter 610 is installed inside the positioning tube 609. The positioning tube 609 is adapted to the positioning hole 413. A limiting mechanism 8 is also arranged inside the storage cylinder 2, and the limiting mechanism 8 is used to limit and fix the fixed column 608.

[0065] Please refer specifically to Figure 7 , Figure 8 and Figure 9 , the positioning mechanism 6 further includes a fixed ring rail 601, a pressure-receiving disc 602 and a moving cylinder 604. Both of the two sliding plates 10 are fixed to the fixed ring rail 601. The pressure-receiving disc 602 is located at the bottom of the fixed ring rail 601. Two sliders 603 are fixed to the outer surface of the pressure-receiving disc 602, and both of the two sliders 603 are slidably connected to the fixed ring rail 601. Two limiting plates 605 are fixed to the outer surface of the moving cylinder 604, and both of the two limiting plates 605 are slidably connected to the pressure-receiving disc 602. A spherical sleeve 606 is fixedly communicated with the top end of the moving cylinder 604. A universal ball 607 is rotatably connected to the inner wall of the spherical sleeve 606, and the universal ball 607 is fixed to the fixed column 608. A first telescopic spring 612 is fixed to the bottom surface of the positioning tube 609, and a baffle 613 is fixed to the outer surface of the fixed column 608. The two ends of the first telescopic spring 612 are respectively fixed to the baffle 613 and the positioning tube 609.

[0066] When measuring and marking the original inclination of the drill hole, first limit and fix the counterweight ball 404 in a vertical state, then freely move the fixed column 608, and quickly position the fixed column 608 by inserting the positioning tube 609 into the positioning hole 413. At this time, the wire harness transmitter 610 can be sensed by the double-hole wire harness receiver 405. Since the central axis of the fixed column 608 coincides with the central axis of the counterweight ball 404 at this time, that is, the central axis of the fixed column 608 coincides with the geocentric vertical line.

[0067] Through the settings of the wire harness emitter 610 and the double-hole wire harness receiver 405, the double-hole wire harness receiver 405 can sense whether the wire harness emitted by the wire harness emitter 610 coincides with the central axis of the counterweight ball 404. If the double-hole wire harness receiver 405 senses the wire harness emitted by the wire harness emitter 610, the central axis of the counterweight ball 404 coincides with the central axis of the fixed column 608.

[0068] A pressing column 614 is slidably connected to the inner wall of the moving cylinder 604. The top end of the pressing column 614 is provided with anti-slip lines. Two pressing plates 615 are fixed to the outer surface of the pressing column 614. Both of the two pressing plates 615 are slidably connected to the moving cylinder 604. Two anti-slip edge strips 617 are fixed to the upper surface of the pressure receiving plate 602. The two anti-slip edge strips 617 respectively correspond to the two pressing plates 615. Two expansion springs II 616 are fixed to the upper surfaces of the two pressing plates 615. Both of the two expansion springs II 616 are fixed to the moving cylinder 604.

[0069] Please refer specifically to Figure 7 and Figure 8 . Linkage mechanisms 7 are arranged outside both of the two sliders 603. The linkage mechanism 7 includes a pressing block 701 and a slide rail 705. The slide rail 705 is fixed to the slider 603. A braking block 704 is slidably connected to the inner wall of the slide rail 705. The braking block 704 is slidably connected to the slider 603. An extrusion rod 703 is fixed to the outer surface of the braking block 704. An inclined chute 702 adapted to the extrusion rod 703 is formed on the outer surface of the pressing block 701. The extrusion rod 703 is slidably connected to the inner wall of the inclined chute 702. A square rod 706 is fixed to the upper surface of the pressing block 701. A fixed seat 707 is fixed to the upper surface of the slider 603. The square rod 706 is slidably connected to the fixed seat 707. An expansion spring III 708 is sleeved on the outer surface of the square rod 706. Two ends of the expansion spring III 708 are respectively fixed to the fixed seat 707 and the pressing block 701.

[0070] When it is necessary to lock the fixed column 608, control the electric push rod II 806 to drive the moving frame 801 to move upward, so that the transmission circular plate 802 presses the pressure receiving plate 602, the pressing column 614 and the pressing block 701, so as to lock the position of the fixed column 608. At the same time, after the pressure receiving plate 602 is pressed, the transmission circular plate 802 is frictionally connected to the pressure receiving plate 602 for transmission;

[0071] Among them, after the pressing column 614 is pressed, the pressing column 614 will press the universal ball 607, so as to limit and fix the universal ball 607, so that the universal ball 607 does not rotate with the spherical sleeve 606. While the pressing column 614 is being pressed, the pressing plate 615 will press the anti-slip edge strip 617, so as to limit and fix the moving cylinder 604, so that the moving cylinder 604 does not slide with the pressure receiving plate 602;

[0072] After the top pressing block 701 is pressed, the inclined chute 702 will squeeze the pressing rod 703, causing the brake block 704 to brake the pressed disc 602, so that the pressed disc 602 does not rotate with the fixed ring rail 601.

[0073] Please refer particularly to Figure 5 and Figure 6 , the limiting mechanism 8 includes a moving frame 801 and a transmission circular plate 802. Limiting rods II 807 are fixed on the outer surfaces of the two sliding plates 10, and both of the two limiting rods II 807 are slidably connected with the moving frame 801. The moving frame 801 is rotationally connected with the transmission circular plate 802. An electric push rod II 806 is fixed on the bottom surface of the plugging shell 3, and the telescopic end of the electric push rod II 806 is fixed to the moving frame 801. A toothed ring 803 is fixed on the outer surface of the transmission circular plate 802. A motor II 804 is fixed below the moving frame 801, and a gear 805 is fixed to the output end of the motor II 804. The gear 805 meshes with the toothed ring 803.

[0074] When the main cylinder 1 slides in the drill hole, the phenomenon that the whole device rotates in the drill hole may occur. In order to prevent the whole device from rotating and causing the position of the fixed column 608 to shift, resulting in the dislocation of the fixed column 608 and the counterweight ball 404, the driving motor II 804 drives the transmission circular plate 802 to rotate. Since the transmission circular plate 802 presses the pressed disc 602, the transmission circular plate 802 is frictionally connected with the pressed disc 602 in transmission. Thus, the rotation of the transmission circular plate 802 drives the pressed disc 602 to rotate, and the rotation of the pressed disc 602 drives the fixed column 608 to rotate around the central axis of the main cylinder 1, thereby avoiding the dislocation of the fixed column 608 and the counterweight ball 404.

[0075] Working principle:

[0076] When detecting the inclination of the drill hole, please refer particularly to Figure 14 and Figure 15 , at this time, it is necessary to first mark and measure the original inclination of the drill hole. Insert the main cylinder 1 into the drill hole, control the three clamping plates 904 to clamp the drill hole wall, so that the central axis of the main cylinder 1 coincides with the central axis of the drill hole. Control the electric push rod I 13 to move the support frame 11, so that the positioning mechanism 6 moves from the inside of the receiving cylinder 2 to the outside of the receiving cylinder 2. The counterweight ball 404 rotates freely under the action of gravity. After the counterweight ball 404 stops, the central axis of the counterweight ball 404 coincides with the geocentric vertical line. Rotate the bidirectional threaded rod 501 to drive the two clamping half rings 502 to approach each other, and the two clamping half rings 502 clamp and fix the anti-slip ring 408, thereby limiting and fixing the counterweight ball 404 in a vertical state.

[0077] Move the fixed column 608 freely, and quickly position the fixed column 608 by inserting the positioning tube 609 into the positioning hole 413. At this time, the wire harness emitter 610 can be sensed by the double-hole wire harness receiver 405. Then, control the second electric push rod 806 to drive the moving frame 801 to move upward, so that the transmission circular plate 802 presses against the pressure-receiving disc 602, the pressure-receiving column 614 and the pressure-receiving block 701. After the pressure-receiving column 614 and the pressure-receiving disc 602 are pressed, the fixed column 608 will be limited and fixed, locking the position of the fixed column 608. After the pressure-receiving disc 602 is pressed, the transmission circular plate 802 is frictionally connected to the pressure-receiving disc 602 for transmission.

[0078] After the fixed column 608 is limited and fixed, at this time, the central axis of the fixed column 608 coincides with the central axis of the counterweight ball 404, that is, the central axis of the fixed column 608 coincides with the plumb line of the earth's center. Then, start drilling and detecting the inclination. At this time, cancel the limitation of the counterweight ball 404, and control the first electric push rod 13 to move the positioning mechanism 6 into the storage cylinder 2. Then, place the device in the detection area and fix it by clamping the drilling wall with three clamping plates 904. After the freely rotating counterweight ball 404 stops, drive the second motor 804 to drive the transmission circular plate 802 to rotate. The rotation of the transmission circular plate 802 drives the pressure-receiving disc 602 to rotate, and the rotation of the pressure-receiving disc 602 drives the fixed column 608 to rotate around the central axis of the main cylinder 1.

[0079] If the drilling in the detection area does not deviate, after the fixed column 608 rotates one week around the central axis of the main cylinder 1, the central axis of the fixed column 608 can finally move to coincide with the central axis of the counterweight ball 404. At this time, the double-hole wire harness receiver 405 can receive the ray of the wire harness emitter 610. Through the information feedback of the double-hole wire harness receiver 405, the staff can directly confirm that the drilling in the detection area is not inclined.

[0080] If the drilling in the detection area deviates, the main cylinder 1 follows the deviation of the drilling, and the central axis of the fixed column 608 also deflects relative to the plumb line of the earth's center. When the fixed column 608 rotates one week around the central axis of the main cylinder 1, the central axis of the fixed column 608 cannot coincide with the central axis of the counterweight ball 404. At this time, the double-hole wire harness receiver 405 cannot receive the ray of the wire harness emitter 610. Through the information feedback of the double-hole wire harness receiver 405, the staff can directly confirm that the drilling is inclined. Then, by recording the deflection angles of the pointer column 406 and the pointer block 411 with the detection head 18, the deviation inclination of the drilling here can be calculated.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
