Description

Technical Field

[0001] This application relates to the field of landslide monitoring equipment technology, and in particular to a deep displacement monitoring device for landslides. Background Technology

[0002] Landslides are a serious geological hazard worldwide. Deep displacement monitoring of landslides is a key link in landslide geological hazard monitoring. It aims to monitor displacement changes at different depths within the landslide body to understand the deformation characteristics, sliding surface location, and development trend of the landslide, thereby providing a scientific basis for landslide early warning, risk assessment, and prevention and control engineering.

[0003] Currently, the displacement is estimated by drilling holes in the most active areas of landslide deformation, installing inclinometers in the holes, measuring the tilt changes of the borehole walls as the landslide deforms.

[0004] Regarding the aforementioned technologies, the applicant believes that current inclinometer tubes are typically fixed with bolts, which requires manual pre-installation before installation into the borehole. This increases the difficulty of installation into the borehole when conducting displacement detection in deep landslide areas, and therefore still needs improvement. Utility Model Content

[0005] To improve the convenience of extending the inclinometer tube and reduce the difficulty of installing the inclinometer tube in the borehole when applying it to displacement detection in deep landslides, this application provides a deep landslide displacement monitoring device.

[0006] The landslide deep displacement monitoring device provided in this application adopts the following technical solution:

[0007] A landslide deep displacement monitoring device includes an inclinometer tube. The inclinometer tube comprises a main body and an extension tube connected by a connecting structure. The connecting structure includes a reduced diameter section extending from the main body, a deformable mounting section extending from the extension tube, and a locking plate movably connected within the reduced diameter section. The mounting section is sleeved outside the reduced diameter section. A deformable locking block is fixed on the side wall of the reduced diameter section, and a locking groove is provided on the mounting section for the locking block to engage and be positioned. The locking plate is driven by the movable structure to pass through the reduced diameter section and be inserted into the mounting section for positioning.

[0008] By adopting the above technical solution, the required length of inclinometer tube is obtained by connecting the main tube and the extension tube. During installation, the main tube can be fixed first, and then the extension tube can be initially positioned by the cooperation of the locking block and the locking groove. Finally, the locking plate is inserted. When applied to displacement detection in deep landslides, the convenience of extending the inclinometer tube is improved, and the difficulty of installing the inclinometer tube in the borehole is reduced.

[0009] Preferably, the locking plate is connected to the reduced diameter section by a connecting spring. The movable structure includes a movable rod and a drive plate. The movable rod is inserted into the reduced diameter section and can rotate. The drive plate is fixed to the side wall of the movable rod and can abut against the locking plate inserted into the mounting section.

[0010] By adopting the above technical solution, the connecting spring enables the locking plate to move, and the moving rod drives the driving plate to rotate, so that the driving plate abuts against the side wall of the locking plate and pushes it out of the reduced diameter section and inserts it into the mounting section for positioning, thereby realizing the mutual connection between the extension tube body and the main tube body.

[0011] Preferably, a mating plate is fixed to the upper part of the movable rod directly above the drive plate, and a deformable limiting plate is fixed to the inner wall of the extension tube and is positioned opposite to it. The mating plate rotates and is positioned between the opposite limiting plates.

[0012] By adopting the above technical solution, the setting of the mating plate makes it easy to observe the rotation position of the drive plate from above, and the limiting plate restricts the position of the mating plate to fix the movable rod, thereby achieving the purpose of stably keeping the locking plate inserted in the installation part and improving the connection stability of the extension tube and the main tube.

[0013] Preferably, the locking plate has an arc-shaped side wall near the drive plate, and a guide block that is slidably connected to the reduced diameter section is fixed at the bottom of the locking plate.

[0014] By adopting the above technical solution, the arc-shaped sidewall of the locking plate is easy to drive the plate to abut and push; the guide block guides the locking plate to slide stably relative to the reduced diameter section, so as to accurately pass through the reduced diameter section.

[0015] Preferably, a guide slide for guiding the sliding of the drive block is fixed on the inner wall of the extension tube, and a guide plate is fixed on the side wall of the movable rod and directly above the drive plate. The guide plate slides along the guide slide, and when the bottom of the movable rod abuts against the reduced diameter section, the guide plate passes through the bottom of the guide slide.

[0016] By adopting the above technical solution, the guide slide allows the movable rod to descend stably along the extended tube. Furthermore, a guide plate is set so that after the drive plate enters the reduced diameter section, it descends stably by relying on the cooperation between the guide plate and the guide slide. This facilitates the movement of the movable rod into position, which drives the drive plate to accurately abut against the locking plate.

[0017] Preferably, the connection structure further includes a positioning plate and a positioning groove. The positioning plate is fixed to the bottom of the mounting part and located on the outside of the locking block. The positioning groove is opened on the main body and allows the positioning plate to be inserted into it.

[0018] By adopting the above technical solution, the positioning plate and the positioning groove cooperate to achieve the lateral positioning of the extension tube and the main tube, preventing the extension tube from rotating relative to the main tube, and the guide block is smoothly engaged in the groove.

[0019] Preferably, a sealing ring is fixed to the upper part of the reduced diameter section, and the sealing ring is tightly attached to the inner wall of the extension tube.

[0020] By adopting the above technical solution, in order to ensure the integrity of the surrounding soil and the inclinometer tube, concrete or mortar is generally poured in. Through the setting of the sealing ring, the concrete or mortar flows into the spliced ​​main tube and extension tube during the pouring process.

[0021] Preferably, the card block is a wedge-shaped block.

[0022] By adopting the above technical solution, both sides of the wedge block are inclined, which facilitates the engagement and disengagement of the block and the slot.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] The required length of inclinometer tube is obtained by connecting the main tube and the extension tube. During installation, the main tube can be fixed first, and then the extension tube can be initially positioned by the cooperation of the clamping blocks and the clamping slots. Finally, the locking plate is inserted. When applied to displacement detection in deep landslides, the convenience of extending the inclinometer tube is improved, and the difficulty of installing the inclinometer tube in the borehole is reduced.

[0025] The guide slide allows the movable rod to descend stably along the extension tube. A guide plate is further provided so that the drive plate, after entering the reduced diameter section, descends stably thanks to the cooperation between the guide plate and the guide slide. This facilitates the movement of the movable rod into position, causing the drive plate to accurately abut against the locking plate. A connecting spring enables the locking plate to move. The movable rod drives the drive plate to rotate, causing it to abut against the side wall of the locking plate and push it out of the reduced diameter section, inserting it into the mounting section for positioning, thus achieving the connection between the extension tube and the main tube. The mating plate facilitates observation of the drive plate's rotation point from above. A limiting plate restricts the position of the mating plate and fixes the movable rod, achieving the goal of stably keeping the locking plate within the mounting section and improving the connection stability between the extension tube and the main tube.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a landslide deep displacement monitoring device, including an inclinometer tube 1, as shown in the following embodiment. Figure 1 The inclinometer tube 1 includes a main tube 2 and an extension tube 3 connected by a connecting structure 4. The connecting structure 4 includes a reduced diameter portion 41 extending from the main tube 2 and a deformable mounting portion 42 extending from the extension tube 3. The mounting portion 42 is fitted over the reduced diameter portion 41. It should be noted that the main tube 2 and the extension tube 3 are hollow inside and have sufficient space outside the required structure to meet the monitoring needs.

[0032] Reference Figure 1 , 2 A sealing ring is fixed to the upper part of the reduced diameter section 41. The sealing ring is tightly attached to the inner wall of the extension pipe. In order to ensure the integrity of the surrounding soil and the inclinometer tube 1, concrete or mortar is usually poured. By setting the sealing ring, the amount of concrete or mortar flowing into the joint between the main pipe 2 and the extension pipe 3 during the pouring process is reduced. In the specific construction, the installation part 42 can be made of rubber material with deformation and sealing properties to further reduce the inflow of concrete or mortar.

[0033] Reference Figure 1 , 2 The connecting structure 4 also includes a positioning plate 43 and a positioning groove 44. The positioning plate 43 is arc-shaped and is positioned opposite to and fixed to the bottom of the mounting part 42. The positioning groove 44 is opened on the main pipe body 2 and allows the positioning plate 43 to be inserted into it. The cooperation between the positioning plate 43 and the positioning groove 44 realizes the lateral positioning of the extension pipe body 3 and the main pipe body 2.

[0034] Reference Figure 1 , 2A deformable rubber block 411 is fixed on the end side wall of the reduced diameter part 41. The block 411 is a wedge-shaped block. A slot 421 is provided through the side wall of the mounting part 42 for the block 411 to engage and be positioned. Both sides of the wedge-shaped block are inclined to facilitate the engagement and disengagement of the block 411 and the slot 421. The positioning plate 43 is first inserted into the positioning groove 44, and then the block 411 corresponds to the slot 421 and engages with the slot 421 through the deformation and reset of the block 411. The block 411 is located inside the positioning plate 43 to avoid structural interference. It should be noted that the reduced diameter part 41 is made of plastic with a certain deformation capacity, which can cooperate with the engagement of the block 411 and also has supporting force.

[0035] Reference Figure 2 The connecting structure 4 also includes a locking plate 45 movably connected to the lower part of the reduced diameter section 41; the locking plate 45 is driven by the movable structure 5 to pass through the outside of the reduced diameter section 41 and is inserted into the mounting section 42 for positioning.

[0036] Reference Figure 1 , 2 The movable structure 5 includes a movable rod 51 and a drive plate 52. The movable rod 51 is inserted into the reduced diameter section 41 and can rotate. A crossbar is fixed inside the reduced diameter section 41 and abuts against the bottom of the movable rod 51. The drive plate 52 is oppositely arranged and fixed to the side wall of the movable rod 51. When the movable rod 51 is rotated, the drive plate 52 can abut against the locking plate 45 and be inserted into the mounting section 42. It should be noted that the movable rod 51 is made of lightweight material to avoid the setting of the movable rod 51 affecting the movement monitoring effect of the inclinometer tube 1.

[0037] Reference Figure 2 , 3 A guide drive plate 52 is fixed on the inner wall of the extension tube 3 and inserted downward into the guide slide 31 of the reduced diameter section 41. A guide plate 511 is fixed in the middle of the side wall of the movable rod 51 and directly above the drive plate 52. The guide plate 511 slides along the guide slide 31. When the bottom of the movable rod 51 abuts against the reduced diameter section 41, the guide plate 511 passes through the bottom of the guide slide 31. The guide slide 31 allows the movable rod 51 to descend stably along the extension tube 3, which facilitates the rotation of the movable rod 51 after it moves into place, causing the drive plate 52 to accurately abut against the locking plate 45.

[0038] Reference Figure 2 The upper part of the locking plate 45 is connected to the reduced diameter section 41 by the connecting spring 6, so that the locking plate 45 has the ability to move; the side wall of the locking plate 45 near the movable rod 51 and the drive plate 52 is arc-shaped, which makes it easy for the drive plate 52 to push against it; the bottom of the locking plate 45 is fixed with a guide block 451 that is slidably connected to the crossbar in the reduced diameter section 41. The guide block 451 guides the locking plate 45 to slide stably relative to the reduced diameter section 41 so as to accurately pass through the reduced diameter section 41.

[0039] Reference Figure 1 , 3 A mating plate 7 is fixed on the upper end side wall of the movable rod 51 and directly above the drive plate 52. The mating plate 7 facilitates observation of the rotation point of the drive plate 52 from above. A deformable and oppositely positioned limiting plate 8 is fixed on the inner side wall of the extension tube 3. The mating plate 7 rotates and abuts against a limiting plate 8, causing it to deform and enter between the opposite limiting plates 8. Then, the deformed limiting plate 8 resets, positioning the mating plate 7 within the opposite limiting plate 8, thereby achieving the purpose of stably keeping the locking plate 45 inserted into the mounting part 42 and improving the connection stability between the extension tube 3 and the main tube 2.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
