[0002] In related technologies, inclinometer tubes are embedded in the soil surrounding an excavated foundation pit to monitor changes in the soil. During excavation, the inclinometer monitors changes by inserting its probe into the bottom of the tube, thus reflecting changes in the surrounding soil. However, due to the deep embedment of the inclinometer tubes and improper operation of the probe, the probe may fall freely during insertion, piercing the bottom of the tube and embedding itself in the soil, becoming stuck.

[0040] In related technologies, inclinometer tubes are installed in the soil surrounding the excavation site to monitor changes in the soil. After installation and during excavation, the inclinometer probe is inserted into the bottom of the tube to monitor its changes, thus reflecting the changes in the surrounding soil. However, due to the deep burial depth of the inclinometer tube, if the probe falls freely due to improper operation, it may pierce the bottom of the tube and penetrate to a certain depth in the soil. Furthermore, because the cable used to pull the probe has low tensile strength, and to ensure its lifespan, it is impossible to pull the probe out by force, resulting in the probe becoming stuck.

[0041] In view of this, the present disclosure provides an extraction device for extracting the probe of an inclinometer from the soil layer.

[0042] Figure 1 This is a schematic diagram of the extraction device according to an embodiment of the present disclosure. Figure 2 This is a schematic diagram showing the working state of the extraction device according to an embodiment of this disclosure. (See attached diagram.) Figure 1 and Figure 2 The extraction apparatus disclosed herein includes an extraction tube 100 and a plurality of extraction components 200.

[0043] The extraction tube 100 is movably fitted around the outside of the probe 91 and the inside of the inclinometer tube 92, and is inserted into the soil layer below the probe 91. In other words, the diameter of the extraction tube 100 is configured to be larger than the outer diameter of the probe 91 and smaller than the inner diameter of the inclinometer tube 92. Thus, the extraction tube 100 can be installed on the outside of the probe 91 and the inside of the inclinometer tube 92. When the extraction tube 100 is fitted between the probe 91 and the inclinometer tube 92, the inclinometer tube 92 can also move axially, i.e., vertically, so that its lower end is inserted into the soil layer at a predetermined position below the probe 91.

[0044] Optionally, the lower end of the extraction tube 100 is provided with a tip 111. Therefore, when the lower end of the extraction tube 100 is inserted into the soil layer, the pressure is concentrated at the tip 111, allowing the extraction tube 100 to penetrate more easily to a predetermined position in the soil layer. This reduces the difficulty of inserting the extraction tube 100 into the soil layer and saves effort.

[0045] Optionally, the side of the tip 111 is arc-shaped, so that when the extraction tube 100 passes through the inclinometer tube 92 and is inserted into the soil layer, the tip 111 of the extraction tube 100 is unlikely to scratch or damage the inclinometer tube 92, thus playing a protective role.

[0046] Optionally, the extraction tube 100 includes multiple splicing pipes 112. These splicing pipes 112 are sequentially spliced ​​vertically. This allows for adjustment of the length of the extraction tube 100 by adjusting the number of splicing pipes 112, thus ensuring that the extraction tube 100 can reach below the jammed probe 91. For example, the upper end of the inclinometer probe 91 is typically connected to the cable 931 released by the rope reel 93. When the probe 91 is jammed by the soil, the depth at which the probe 91 is jammed can be roughly determined by the length of the cable 931 released by the rope reel 93 and the height of the probe 91 itself. Based on this, the extraction tube 100 is formed by splicing pipes to ensure that the height of the extraction tube 100 is greater than the depth at which the probe 91 is jammed, thereby ensuring that when the extraction tube 100 is inserted into the soil, the lower end of the extraction tube 100 is located at the target position below the probe 91.

[0047] Specifically, the splicing tube 112 can be a threaded tube. Multiple threaded tubes are spliced ​​vertically in sequence to form the extraction tube 100. The threaded splicing operation is convenient and easy to perform.

[0048] Multiple extraction components 200 are disposed inside the extraction tube 100, and are spaced apart circumferentially along the extraction tube 100, so as to penetrate the soil layer with the extraction tube 100 to reach the target position below the probe 91. In other words, when the lower end of the extraction tube 100 is inserted into the soil layer, the multiple extraction components 200 can reach the target position below the probe 91, which is stuck in the soil layer, as the extraction tube 100 is inserted.

[0049] It is understood that "multiple extraction components 200" refers to the number of extraction components 200 being two or more, for example, Figure 3 yes Figure 2 See the example diagram when there are four extraction components 200 described above. Figure 3 The four extraction components 200 are evenly spaced along the circumference of the extraction tube 100. However, it is understood that the number of extraction components 200 in this disclosure is not limited to this, and the number of extraction components 200 can be adjusted adaptively according to needs.

[0050] Figure 4 This is a schematic diagram of the structure of an extraction component 200 according to an embodiment of the present disclosure at an angle. (See also...) Figure 2 and Figure 4Each extraction component 200 includes a rotating member 12 and a limiting mechanism 13. The rotating member 12 is rotatably disposed relative to the extraction tube 100 in both a retracted and an extended position. When the extraction tube 100 is inserted into the soil layer, the rotating member 12 is in the retracted position to create space between the multiple extraction components 200 to allow the probe 91 to pass. Thus, when an external force drives the extraction tube 100 downward into the soil layer to move the multiple extraction components 200 to the target position, the multiple rotating members 12 can avoid the probe 91 in the radial space of the extraction tube 100, without interfering with the probe 91, and the multiple rotating members 12 can be smoothly inserted into the target position.

[0051] When the extraction tube 100 is pulled out of the soil layer, the rotating member 12 is in the extended position to confine the space and support the probe 91. Thus, when an external force drives the extraction tube 100 upwards out of the soil layer, causing the multiple extraction components 200 to move upwards and closer to the probe 91, due to the upward movement of the extraction tube 100 and the interference of the soil and the probe 91 on the rotating member 12, the rotating member 12 will rotate and unfold relative to the inner wall of the extraction tube 100 within the soil layer. This expands the space occupied by the rotating member 12 in the radial direction of the extraction tube 100, supporting the probe 91 and the soil.

[0052] Optionally, each of the rotating members 12 has an extension portion 121 at its free end away from the inner wall of the extraction tube 100. In the retracted position, the extension portion 121 extends obliquely from bottom to top in a direction from near to far relative to the inner wall of the extraction tube 100. In the extended position, the extension portion 121 extends obliquely from top to bottom in a direction from near to far relative to the inner wall of the extraction tube 100. Thus, when the rotating member 12 is in the retracted position and the extraction tube 100 is pulled upward, the extension portion 121 can better withstand the pressure of the soil and the probe 91 and expand radially along the extraction tube 100 under pressure, making it easier for the rotating member 12 to rotate and expand within the soil.

[0053] Optionally, the extension portion 121 extends in an arc shape on its side, such as a semi-circular arc shape, which helps to prevent the extension portion 121 from scratching or damaging the probe 91, thus protecting the probe 91.

[0054] Specifically, when the rotating member 12 is in the retracted position, the rotating member 12 can be in a vertical state, and the extension portion 121 extends obliquely from bottom to top in the direction from near to far relative to the inner wall of the extraction tube 100. The rotating member 12 occupies a small space in the radial direction of the extraction tube 100, and a space with a radial dimension larger than the diameter of the probe 91 is formed between multiple rotating members 12. Thus, when the extraction tube 100 is inserted to the target position below the probe 91, multiple rotating members 12 can avoid the probe 91 in the radial space of the extraction tube 100 and can be smoothly inserted to the target position below the probe 91.

[0055] During the process of the extraction tube 100 being inserted and withdrawn from the soil layer, the extension part 121 will be interfered with by the soil layer above it and the probe 91, causing the rotating part 12 to rotate and unfold, reaching a horizontal state (i.e., Figure 4 (as shown in the diagram), at this time the rotating component 12 occupies a large space in the radial direction of the extraction tube 100, and multiple rotating components 12 support the probe 91.

[0056] The limiting mechanism 13 is provided corresponding to the rotating member 12 to limit the further unfolding of the rotating member 12 in the unfolded position. Thus, when the multiple rotating members 12 support the probe 91 and continue to move upward under the action of the extraction tube 100, the limiting mechanism 13 prevents the rotating members 12 from continuing to unfold, allowing them to maintain the state of supporting the probe 91 until the probe 91 is extracted from the inclinometer tube 92. For example, when in the unfolded position and the rotating member 12 is horizontal, the limiting mechanism 13 can prevent the rotating member 12 from continuing to rotate downward, preventing the multiple rotating members 12 from continuing to unfold downward due to the weight of the soil and the probe 91.

[0057] In some examples, the limiting mechanism 13 includes a locking structure. The locking structure locks the rotating member 12 in the unfolded position. Thus, because the rotating member 12 is locked by the locking structure, it will be locked in the unfolded position and will not continue to unfold from there.

[0058] Optionally, each extraction component 200 further includes a connector 14. The connector 14 is fixedly connected to the inner wall of the extraction tube 100 and is rotatably connected to the rotating component 12 about a transverse axis L.

[0059] Optionally, the extraction assembly 200 further includes a first connecting shaft 15 and a second connecting shaft 16. The first connecting shaft 15 and the second connecting shaft 16 are aligned along the transverse axis L and are rotatably fitted inside the connector 14 and the rotating member 12, so that the rotating member 12 can rotate about the transverse axis L where the first connecting shaft 15 and the second connecting shaft 16 are located.

[0060] Specifically, the connector 14 has a connecting bottom wall 141, a first connecting side wall 142, and a second connecting side wall 143. The first connecting side wall 142 and the second connecting side wall 143 are connected to the same side of the connecting bottom wall 141 and are arranged opposite to each other and spaced apart. The rotating member 12 has a rotating bottom wall 122, a first rotating side wall 123, and a second rotating side wall 124. The first rotating side wall 123 and the second rotating side wall 124 are connected to the same side of the rotating bottom wall 122 and are arranged opposite to each other and spaced apart. The rotating member 12 is disposed between the first connecting side wall 142 and the second connecting side wall 143, and the first connecting side wall 142 and the first rotating side wall 123 are rotatably connected by the first connecting shaft 15. The second connecting side wall 143 and the second rotating side wall 124 are rotatably connected by the second connecting shaft 16.

[0061] One of the rotating member 12 and the connecting member 14 is provided with an arc-shaped guide hole 144, which has a locking section 145. The locking structure includes a lock cylinder 131 and an elastic member 132. The lock cylinder 131 is movably inserted through the arc-shaped guide hole 144 along its extension direction and is axially movably inserted into the other of the rotating member 12 and the connecting member 14, and has a locking section 1311 adapted to the locking section 145. For example, when the connecting member 14 is provided with the arc-shaped guide hole 144, the lock cylinder 131 is axially movably inserted into the rotating member 12. Alternatively, when the rotating member is provided with the arc-shaped guide hole, the lock cylinder is axially movably inserted into the connecting member.

[0062] When the rotating member 12 is in the unfolded position, the locking segment 1311 is located within the locking hole segment 145 to lock the rotation of the rotating member 12 and the movement of the lock cylinder 131 along the arc-shaped guide hole 144. When the rotating member 12 is in the retracted position, the locking segment 1311 disengages from the locking hole segment 145 to unlock the rotation of the rotating member 12 and the movement of the lock cylinder 131 along the arc-shaped guide hole 144. The elastic member 132 is disposed between the lock cylinder 131 and the rotating member 12 to provide the lock cylinder 131 with a spring force that causes the locking segment 1311 to move axially back to the locking hole segment 145.

[0063] Optionally, the outer diameter of the locking segment 1311 gradually decreases in a conical shape along the direction close to the locking hole segment 145. This allows the locking segment 1311 to easily enter and engage within the locking hole segment 145.

[0064] Figure 5 This is a schematic diagram of the extraction component according to an embodiment of the present disclosure from another angle. (See also...) Figure 4 and Figure 5 The lock cylinder 131 is also provided with a radially protruding anti-disengagement section 1313, which abuts against the rotating member 12 or the connecting member 14 inserted by the lock cylinder 131 when the locking section 1311 is located in the locking hole section 145, so as to prevent the lock cylinder 131 from disengaging from the rotating member 12 or the connecting member 14.

[0065] Optionally, see Figure 4 The lock cylinder 13 is also provided with an unlock button 1312 for pressing at its end. Thus, when the unlock button 1312 is pressed along the axial direction of the lock cylinder 131, the locking section 1311 will disengage from the locking hole section 145, making it convenient for the rotating member 12 to rotate back to the retracted position.

[0066] In other words, when the rotating member 12 is in the retracted position, the lock cylinder 131 is located within the arc-shaped guide hole 144, except for the locking hole segment 145. For example, the smaller diameter portion between the unlock button 1312 and the locking hole segment 145 is located within the arc-shaped guide hole 144 and at the other end of the arc-shaped guide hole 144 away from the locking hole segment 145. At this time, the elastic member 132 is in a compressed state, and in the axial direction of the lock cylinder 131, the locking segment 1311 is located outside the arc-shaped guide hole 144 and cannot enter the arc-shaped guide hole 144. The lock cylinder 131 has the degree of freedom to translate within the arc-shaped guide hole 144 along the extension direction of the arc-shaped guide hole 144. As the extraction tube 100 is pulled out, when the rotating member 12 rotates and unfolds, the lock cylinder 131 will move towards the locking hole section 145 in the arc-shaped guide hole 144 as the rotating member 12 rotates, until the locking section 1311 of the lock cylinder 131 reaches the position corresponding to the locking hole section 145 along the axial direction. At this time, since the locking section 1311 is adapted to the locking hole section 145, under the elastic force of the elastic member 132, the locking section 1311 moves along the axial direction of the lock cylinder 131 and is driven into the locking hole section 145. Since the rotating member 12 can only rotate on one axis, the rotating member 12, which has two axes of rotation (the horizontal axis L and the axis where the center of the lock cylinder 131 is located at this time), can no longer rotate. Therefore, when the rotating member 12 is unfolded to a predetermined state (e.g., the horizontal state in the figure), it is automatically locked, realizing self-locking.

[0067] In other examples, the limiting mechanism 13 includes a blocking structure (e.g., a fixed blocking block). The blocking structure is fixed to the extraction tube 100 and located below the rotating member 12. for The obstruction structure prevents the rotating member 12 from rotating downward from the unfolded position. Therefore, when the rotating member 12 has a tendency to rotate downward, the obstruction structure blocks the rotating member 12, restricting its downward rotation. Consequently, the rotating member 12 will not continue to rotate downward from the unfolded position.

[0068] See Figure 2 This disclosure provides an inclinometer comprising an inclinometer and an extraction device as described in any of the examples above. The inclinometer has a probe 91 for insertion into an inclinometer tube 92. The extraction device is used to extract the probe 91 from the inclinometer tube 92.

[0069] Optionally, the probe 91 is provided with a rotating shaft 911, and each end of the rotating shaft 911 is provided with a pulley 912. The pulley 912 is slidably engaged in a vertically extending guide groove inside the inclinometer tube 92, which helps to ensure the stability of the probe 91 during downward detection. Simultaneously, during the downward insertion of the extraction tube 100 into the soil, if the extraction component 200 interferes with the pulley 912, the interference will cause the rotating shaft 911 to rotate. The rotation of the rotating shaft 911 will cause the pulley 912 to rotate around the center position of the middle part of the rotating shaft 911, thereby disengaging from the guide groove and avoiding the extraction component 200, without affecting the extraction of the probe 91 by the extraction component 200. Of course, it is understood that the guide groove may not be provided inside the inclinometer tube 92, and the rotating shaft 911 and the pulley 912 may not be provided on the probe 91. This disclosure does not impose specific limitations on the shape of the probe 91.

[0070] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
