Description

Technical Field

[0001] This utility model relates to the field of landslide monitoring technology, and more specifically, to an anti-displacement mechanism for a landslide monitoring device. Background Technology

[0002] Landslide monitoring devices are used to monitor changes in landslide deformation, displacement, and stress in real time. Preventing displacement of these devices is crucial, as displacement distorts monitoring data, failing to accurately reflect the true deformation of the landslide and affecting the accuracy of early warnings. Once the device is displaced, the monitoring baseline changes, data continuity is compromised, and it becomes difficult to determine the landslide's development trend.

[0003] Patent CN222209577U discloses an anti-displacement mechanism for a landslide monitoring device. The mechanism involves initially fixing the device by inserting a first fixing cone into the soil or rock layer. Once the base is in contact with the ground, a second fixing cone increases friction. Based on the actual situation of the monitoring device body and the ground, the position of the moving plate is adjusted via a sliding groove, connecting the telescopic fixing rod to the ground. The telescopic fixing rod rotates around a rotating rod to achieve fixation in four directions. However, in this anti-displacement device, the moving plate and the sliding groove are slidably connected. After fixing the monitoring device body with the telescopic fixing rod, the moving plate can slide along the sliding groove, so there is still a possibility that the monitoring device body cannot be stably fixed. Furthermore, since the first fixing cone is fixed to the base, fixing the monitoring device body requires inserting the first fixing cone deep into the soil or rock layer. This structural design makes it inconvenient to apply downward force, thus creating operational difficulties in fixing the base. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide an anti-displacement mechanism for a landslide monitoring device.

[0006] It also includes a base fixed to the bottom end of the main rod for fixing to the ground;

[0007] The main rod is also equipped with an adjustable auxiliary fixing structure; the adjustable auxiliary fixing structure includes a hoop connected to the main rod, a connecting plate that can be selectively installed on the hoop, a fixing plate installed on the ground, and a support rod connecting the connecting plate and the fixing plate.

[0008] Furthermore, the lower end face of the base is fixed with several fixing cones, and the base has four first through holes, which are fixed to the ground by anchor rods or anchor bolts and other fixing structures.

[0009] Furthermore, the hoop is a ring with an axial notch; the hoop has circumferentially arranged grooves; the connecting plate can slide along the grooves to a preset position and be fixed.

[0010] Furthermore, the groove is a T-shaped groove.

[0011] Furthermore, the hoop is provided with an upper fixing hole and a lower fixing hole arranged in a ring matrix for fixing to the connecting plate and the main rod.

[0012] Furthermore, the main rod is provided with an upper mounting hole corresponding to the upper fixing hole, and also with a lower mounting hole corresponding to the lower fixing hole.

[0013] Furthermore, the connecting plate includes an integrally arranged T-shaped plate, a positioning plate, and a first connecting ear; the T-shaped plate can slide along the slide groove and is fixed to a set of adjacent upper and lower fixing holes; the positioning plate is located on the outside of the hoop; the first connecting ear is located at the center of the outer wall of the positioning plate.

[0017] The anti-displacement mechanism of this landslide monitoring device employs a hoop and connecting plate structure. The hoop can move within the groove to a preset installation position, and is then connected to the hoop via the connecting plate, which in turn fixes it to the main pole. The connecting plate is connected to a fixed plate anchored to the ground via a support rod.

This anti-displacement mechanism, through an adjustable auxiliary fixing structure, flexibly adjusts the position and direction of the support rod according to ground conditions, enhancing the stability of the main pole and preventing displacement under complex terrain or external forces, thereby ensuring the accuracy of landslide monitoring data.

[0018] The anti-displacement mechanism of this landslide monitoring device uses a base that adheres to the ground via a fixed cone to increase friction, while simultaneously securing it to the ground with anchor bolts or ground bolts passing through the first through hole in the base. This fixing method is simple and easy to implement, reduces operational difficulty, and improves the reliability of the base fixation. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1-4 As shown, this embodiment provides an anti-displacement mechanism for a landslide monitoring device, including a main pole 1, on which a monitoring instrument body 2, a solar panel 3, and a sensor 4 are mounted. It also includes a base 5 fixed to the bottom of the main pole 1, thus securing it to the ground. An adjustable auxiliary fixing structure is used to provide auxiliary support for the main pole 1, preventing it from shifting and ensuring the accuracy of landslide monitoring.

[0037] In this embodiment, as Figure 2 As shown, several fixing cones 51 are fixed to the lower end face of the base 5. During installation, the fixing cones 51 are in contact with the ground, increasing the friction between the base 5 and the ground and ensuring that the monitoring equipment will not shift. Four first through holes 52 are provided in the base 5, and the base 5 is fixed to the ground by anchor rods or anchor bolts. This fixing method is simple and easy to operate and can achieve the fixation of the landslide monitoring device.

[0038] In this embodiment, the adjustable auxiliary fixing structure includes a hoop 6 connected to the main rod 1, a connecting plate 7 that can be selectively installed on the hoop 6, a fixing plate 8 installed on the ground, and a support rod 9 connecting the connecting plate 7 and the fixing plate 8.

[0039] Specifically, such as Figures 4-6 As shown, the hoop 6 is a ring with an axial notch 61. The hoop 6 has circumferentially arranged sliding grooves 62, which are T-shaped grooves. The opening of the sliding grooves 62 faces outwards from the hoop 6, allowing the connecting plate 7 to slide along the sliding grooves 62 to a preset position and be fixed. The hoop 6 has upper fixing holes 63 and lower fixing holes 64 arranged in a ring matrix. Both upper fixing holes 63 and lower fixing holes 64 are threaded holes. The upper fixing holes 63 are located above the lower fixing holes 64 and are used to fix the connecting plate 7 and the main rod 3. In this embodiment, there are six upper fixing holes 63 and six lower fixing holes 64.

[0040] Furthermore, the main rod 1 has an upper mounting hole 11 corresponding to the upper fixing hole 63, and a lower mounting hole 12 corresponding to the lower fixing hole 64. The upper mounting hole 11 and the lower mounting hole 12 are also threaded holes.

[0041] Accordingly, such as Figures 4-6As shown, the connecting plate 7 includes an integrally arranged T-shaped plate 71, a positioning plate 72, and a first connecting lug 73. The T-shaped plate 71 is adapted to the sliding groove 62 of the hoop 6, and can slide along the sliding groove 62, and is fixed to one set of adjacent upper fixing holes 63 and lower fixing holes 64. The positioning plate 72 is an arc-shaped plate, the curvature of which is adapted to the curvature of the outer wall of the hoop 6. The positioning plate 72 is located on the outside of the hoop 71, and the middle of the inner sidewall of the positioning plate 72 is connected to the T-shaped plate. The positioning plate 72 also has an upper through hole 721 and a lower through hole 722, which are adapted to one set of upper fixing holes 63 and lower fixing holes 64 of the hoop, respectively. When the connecting plate 7 slides to the preset installation position of the slide groove 62, a bolt is used to pass through the upper through hole 721 of the connecting plate 7, the upper fixing hole 63 of the hoop 6 and the upper mounting hole 11 of the main rod 1 in sequence, and another bolt is used to pass through the lower through hole 722 of the connecting plate 7, the lower fixing hole 64 of the hoop 6 and the lower mounting hole 12 of the main rod 1 in sequence. Since the upper through hole 721, the upper mounting hole 11, the lower through hole 722 and the lower fixing hole 64 are threaded holes, the bolts are tightened to achieve the simultaneous fixed installation of the connecting plate 7 and the hoop 6 on the main rod 1.

[0042] The first connecting ear 73 is located at the center of the outer wall of the positioning plate 72. The first connecting ear 73 has a first connecting hole 731 for connecting to the top of the support rod 9.

[0043] Correspondingly, a plurality of second connecting ears 81 are fixedly connected to the upper end surface of the fixing plate 8. The second connecting ears have second connecting holes 811 for connecting to the bottom end of the support rod 9. In this embodiment, three second connecting ears 81 are provided, but other numbers can be provided in actual applications. The fixing plate 8 also has a second through hole 82, through which a fixing structure such as an anchor rod or anchor bolt passes to fix it to the ground. The installation position of the fixing plate 8 is adapted to the installation position of the connecting plate 7 on the hoop 6, that is, the perpendicular bisector of the two second connecting holes 811 in the fixing plate 8, the line connecting the center of the upper through hole 721 and the lower through hole 722 of the connecting plate 7, and the central axis of the main rod 1 are located in the same plane.

[0044] The support rod 9 has an upper connecting hole 91 and a lower connecting hole 92 at both ends. The upper connecting hole 91 is bolted to the first connecting lug 73 in the connecting plate 7, and the lower connecting hole 92 is bolted to one of the second connecting lugs 81 in the fixing plate 8. The top end of the support rod 9 is fixed to the connecting plate 7. Depending on the installation ground conditions, the support rod 9 can be selectively installed in one of the second connecting lugs 81 in the fixing plate 8.

[0045] In this embodiment, the landslide monitoring device adopts a GNSS displacement monitoring instrument. The monitoring instrument body 2 and the solar panel 3 are connected to the main pole 1 by clamps. The sensor 4 is located at the top of the main pole 1. The connection method between the monitoring instrument body 2, the solar panel 3, the sensor 4 and the main pole 1, as well as the principle of displacement monitoring, are all existing technologies and will not be described in detail here.

[0046] The anti-displacement mechanism of the landslide monitoring device provided in this embodiment achieves the monitoring device's stability through the fixing of the base to the ground and the function of an adjustable auxiliary fixing structure. Specifically, the fixing cone 51 on the lower end face of the base 5 is in contact with the ground, increasing the friction between the base 5 and the ground, thus initially fixing the device. Simultaneously, anchor bolts or ground bolts pass through the first through hole 52 of the base 5, further firmly fixing the base 5 to the ground. The anti-displacement mechanism of this landslide monitoring device also includes an adjustable auxiliary fixing structure consisting of a hoop 6, a connecting plate 7, a fixing plate 8, and a support rod 9, which can provide auxiliary support for the main rod 1. The connecting plate 7 can slide into the groove 62 through the notch 61 of the hoop 6, sliding to the upper fixing hole 63 and lower fixing hole 64 where it needs to be installed. Bolts are inserted to fix the positioning plate 72 to the hoop 6, and then to the main rod 1. The connecting plate 7 is connected to the fixing plate 8 fixed to the ground through the support rod 9. This structure allows adjustment of the position and direction of the support rod 9 according to the ground conditions, further enhancing the stability of the main rod and preventing its displacement.

[0047] The anti-displacement mechanism of the landslide monitoring device provided in this embodiment adopts a structure of hoop 6 and connecting plate 7. The hoop 6 can move to a preset installation position within the sliding groove 62, and then is connected to the hoop 6 via the connecting plate 7, thereby fixing it to the main rod 1. The connecting plate 7 is connected to the fixing plate 8 fixed to the ground via the support rod 9. After the connecting plate 7 slides to the preset position within the sliding groove of the hoop 6 and is fixed, it is then fixed to the main rod 1, ensuring a stable position that will not move due to external forces, thus ensuring the overall stability of the device. This anti-displacement mechanism, through an adjustable auxiliary fixing structure, can flexibly adjust the position and direction of the support rod according to the ground conditions, further enhancing the stability of the main rod 1 and preventing it from shifting under complex terrain or external forces, thereby ensuring the accuracy of landslide monitoring data.

[0048] The anti-displacement mechanism of the landslide monitoring device provided in this embodiment uses a base 5 that adheres to the ground via a fixing cone 51 to increase friction, while simultaneously using anchor rods or anchor bolts passing through the first through hole 52 of the base 5 to fix it to the ground. This fixing method is simple and easy to operate, reduces operational difficulty, and improves the reliability of the base fixing.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
