Description

Technical Field

[0001] The present invention relates to the technical field of displacement monitoring, and particularly to a sensor and a geological disaster deep displacement monitoring device using the sensor. Background Art

[0002] The deep displacement of geological disasters refers to the displacement and deformation phenomenon of rock and soil masses at a certain depth (usually several meters to dozens of meters) below the ground surface. Generally, it refers to the concealed displacement occurring inside geological disaster bodies such as landslides and collapses, which needs to be detected by professional equipment such as monitoring borehole inclinometers equipped with mechanical detection sensors and fiber optic monitoring, forming a complement to surface displacement monitoring. By placing the inclinometer at different depths in the inclinometer borehole, the data of the offset in the X-axis and Y-axis are monitored. After the inclinometer is connected to the transmission wire, it is manually placed into the inclinometer borehole.

[0003] The invention with the publication number CN214039949U discloses a sensor and a geological disaster deep displacement monitoring device using the sensor. By setting an inclinometer tube and a sealing plug, it is convenient to seal the bottom of the inclinometer tube to prevent sundries from entering. By setting a bottom plate, fixing columns, convex grooves, return springs, movable columns, top plates and displacement monitors, it is convenient to make the displacement monitor have an anti-vibration effect. By setting a protective ring, it is convenient to prevent the inner wall of the inclinometer tube from knocking against the displacement monitor and affecting the use of the displacement monitor, so as to achieve the effect of facilitating the protection of the sensor and the geological disaster deep displacement monitoring device using the sensor.

[0004] The utility model with the publication number CN215909833U discloses a sensor and a geological disaster deep displacement monitoring device using the sensor. Through four upper cleaning wheels and four lower cleaning wheels, no matter whether the inclinometer moves upward or downward in the inclinometer tube, the soil blocks and other sundries in the slide rail can be cleaned out first, so that the four upper traveling wheels and the four lower traveling wheels can move smoothly in the slide rail, ensuring the accuracy of the monitoring data; rotating the reel can drive the inclinometer to move upward from the bottom of the inclinometer tube, and multiple traveling driving motors can provide power for the inclinometer to prevent the problem that the inclinometer cannot fall to the bottom of the inclinometer tube due to the inclination of the inclinometer tube.

[0005] However, the above-disclosed sensor and the geological disaster deep displacement monitoring device using the sensor still have the following problems in the actual use process: Although the corresponding brackets are used to assist the monitoring device to achieve retraction and detection, such auxiliary mechanisms can only maintain a certain stability relative to the ground, and cannot guarantee the accuracy relative to the inclinometer borehole during the offset process, which easily causes friction between the transmission cable connected to the monitoring device and the detection hole. At the same time, some monitoring holes contain sediment, which is wound up after sticking to the transmission cable, and then continuous extrusion and friction cause damage and other situations.

[0006] Therefore, we propose a sensor and a deep displacement monitoring device for geological disasters using this sensor to facilitate the solution of the problems raised above. Summary of the Invention

[0007] The object of the present invention is to provide a sensor and a deep displacement monitoring device for geological disasters using this sensor. To solve the problem that in the prior art, the retraction and detection are realized by means of a corresponding bracket-assisted monitoring device, but such an auxiliary mechanism can only maintain a certain stability relative to the ground, and cannot guarantee the accuracy relative to the inclinometer hole during the offset process, which easily causes friction between the transmission cable connected to the monitoring device and the detection hole.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1-12 , the present invention provides the following technical solutions:

[0042] Embodiment 1: In order to solve the problems existing in the use of existing sensors and geological disaster deep displacement monitoring devices using such sensors, therefore, in this embodiment, through the following technical solutions, a sensor includes a mechanical monitoring sensor 32 and a monitor 1 for installing the mechanical monitoring sensor 32; inclination measurement modules 30 are arranged on both the upper and lower sides of the mechanical monitoring sensor 32, and the inclination measurement modules 30 are connected to the mechanical monitoring sensor 32; the inclination measurement modules 30 monitor the deep displacement of geological disasters by flipping, and the monitoring information of the inclination measurement modules 30 is integrated and transmitted by the mechanical monitoring sensor 32.

[0043] A geological disaster deep displacement monitoring device for a sensor, the lower part of the monitor 1 includes an inclination measurement hole 2 for in-depth monitoring, and the top of the monitor 1 is detachably connected to the bottom end of a transmission cable 3. The transmission cable 3 is used to transmit the collected information of the inclination measurement modules 30 and the mechanical monitoring sensor 32. Moreover, inclination measurement brackets 29 are rotatably arranged on the upper and lower sides inside the monitor 1 through bearings. The middle part of the inclination measurement brackets 29 is fixedly installed with the inclination measurement modules 30, and a guiding runner 31 is rotatably installed at the outer end of the inclination measurement brackets 29.

[0044] As Figure 1 , Figure 12 shown, when the monitor 1 is lowered into the inclination measurement hole 2, the top of the monitor 1 is connected to the transmission cable 3. The inclination measurement brackets 29 and the guiding runner 31 on the upper and lower sides outside the monitor 1 are attached to the inner wall of the inclination measurement hole 2.

[0045] Embodiment 2: To solve the problems existing in the use of existing sensors and the deep displacement monitoring device for geological disasters using such sensors, a positioning mechanism is provided below the retractable platform 4. The positioning mechanism includes a positioning rotating cylinder 6, and an extension contact rod 7 for making contact and limiting the outside of the inclinometer hole 2 is elastically slidably arranged inside the positioning rotating cylinder 6. The positioning mechanism includes a positioning column 16, and the positioning column 16 is fixedly installed at the four corners of the bottom surface of the retractable platform 4. The bottom end of the positioning column 16 is fixedly installed with a lifting slide rod 17, and the lifting slide rod 17 slidably penetrates through the upper end of the moving guide wheel 18. At the same time, a linkage bracket 19 is fixedly installed between adjacent moving guide wheels 18.

[0046] The positioning mechanism includes a positioning horizontal plate 20, and the positioning horizontal plate 20 is fixedly installed below adjacent positioning columns 16. The middle part of the bottom surface of the positioning horizontal plate 20 is rotatably installed with a lifting screw rod 21 through a bearing. At the same time, the lower end of the lifting screw rod 21 is threadedly connected through the middle part of the linkage bracket 19. The rotation of the lifting screw rod 21 drives the linkage bracket 19 and the moving guide wheel 18 to move up and down.

[0047] As Figures 4-6 shown, the positioning column 16 included in the positioning mechanism is fixedly installed at the bottom end of the retractable platform 4. The moving guide wheel 18 at the bottom end of the positioning column 16 is in the lowest position in the initial state, so as to facilitate the retractable platform 4 to move and transport the monitor 1 and the retractable roller 5 to transport the transmission cable 3, so that the retractable platform 4 is erected at the top center position of the inclinometer hole 2. Then, the servo motor on the top of the positioning horizontal plate 20 drives the lifting screw rod 21 to rotate, so that the linkage bracket 19 threadedly connected to the lifting screw rod 21 moves upward, and at the same time drives the outer moving guide wheel 18 to rise along the direction of the lifting slide rod 17. After falling off the contact with the ground, the positioning column 16 supports the retractable platform 4 to avoid deviation due to terrain problems during the monitoring process.

[0048] Embodiment 3: To solve the problems existing in the use of existing sensors and the deep displacement monitoring device for geological disasters using such sensors, the outer end of the positioning rotating cylinder 6 included in the positioning mechanism is fixedly installed at the bottom end of the lifting screw 21, and a threaded sleeve 22 is rotatably arranged inside the positioning rotating cylinder 6 through a bearing.

The bottom end of the positioning screw 26 included in the positioning mechanism slidably penetrates through the outside of the bottom surface of the positioning rotating cylinder 6, and an earth-entering cone head 28 is fixedly installed at the bottom end of the positioning screw 26. The earth-entering cone head 28 is screwed into the ground by descending to improve the stability during monitoring.

[0049] As Figures 7-9 shown, the rotating lifting screw 21 drives the positioning rotating cylinder 6 at the bottom end to rotate towards the direction of the inclinometer hole 2. The positioning rotating cylinder 6 drives the extension contact rod 7 to approach the inclinometer hole 2 and causes extrusion. Then, the extension contact rod 7 slides towards one side of the positioning rotating cylinder 6, and during the sliding process, the secondary driving rack 24 inside the sliding guide groove 25 meshes with the main driving rack 23 to drive the threaded sleeve 22 to rotate. The positioning screw 26 threadedly connected to the threaded sleeve 22 is limited by the limit slide rod 27, so that the positioning screw 26 drives the earth-entering cone head 28 at the bottom end to enter the corresponding ground. After the inner end of the extension contact rod 7 fits against the outer wall of the inclinometer hole 2, the second positioning is realized through the earth-entering cone head 28 to prevent the retracting and extending platform 4 from being misaligned relative to the inclinometer hole 2 during the detection process of the monitor 1.

And the inside of the guiding flat plate 11 is slidably penetrated through the upper end of the guiding slider 10. Moreover, the top end of the guiding slider 10 is fixedly installed with a guiding through pipe 12. And the guiding through pipe 12 is sleeved outside the transmission cable 3 to wind and unwind it reciprocally.

[0051] The winding and unwinding mechanism includes a dust-removing roller 13, and the dust-removing roller 13 is rotatably arranged through a bearing on the front and rear sides of the lower part of the winding and unwinding platform 4. And the other end of the reciprocating lead screw 8 included in the winding and unwinding mechanism is meshed with one end of the rear dust-removing roller 13 through a transmission gear 14. Moreover, a driven gear 15 is meshed in front of the transmission gear 14 at the end of the rear dust-removing roller 13. At the same time, the driven gear 15 is fixedly installed at the end of the front dust-removing roller 13; The rotation directions of the dust-removing rollers 13 on the front and rear sides included in the winding and unwinding mechanism are set to be opposite to each other. And the dust-removing rollers 13 on the front and rear sides are used to clean and scrape the soil and dust on the outer wall of the transmission cable 3 during the winding and unwinding process, so as to avoid damage to the transmission cable 3 caused by friction due to sticking of dust during winding and unwinding.

[0052] As Figures 10-12 shown, the bottom end of the transmission cable 3 penetrates into the inside of the guiding through pipe 12 and then leads out, passes through between the dust-removing rollers 13 on the front and rear sides, and then is connected to the bottom end of the monitor 1. Finally, the monitor 1 is placed inside the inclinometer hole 2. At the same time, after rotating the winding and unwinding platform 4, the transmission cable 3 is released. At the same time, the reciprocating lead screw 8 is driven to rotate through the pulley assembly 9. The guiding slider 10 connected by threads is limited by the guiding flat plate 11, and then drives the guiding through pipe 12 and the transmission cable 3 inside to wind and unwind reciprocally, so as to avoid the cable from piling up on the same side of the winding and unwinding platform 4.

[0053] Further, the reciprocating lead screw 8 drives the dust removal roller 13 at the rear to rotate through the transmission gear 14, and the dust removal rollers 13 on both the front and rear sides are meshed through the driven gears 15, so that the dust removal rollers 13 rotating in the reverse direction clean the transmission cable 3 during winding and unwinding, avoiding friction and damage to the transmission cable 3 caused by sticky soil and dust, and improving the stability and data accuracy of the transmission cable 3 and the monitor 1 during winding, unwinding and monitoring.
