Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a monitoring device for slope softening. Background Technology

[0002] Slope protection systems primarily consist of various flexible nets, mainly steel wire rope mesh, covering and wrapping the slope to be protected to limit weathering and erosion of the rock and soil. Active slope protection systems also use various flexible nets, primarily steel wire rope mesh, to cover and wrap the slope or rock to limit weathering and erosion of the rock and soil, prevent rockfalls, or control the movement of falling rocks within a certain range. Landslides are caused by factors such as river erosion, groundwater activity, rainwater soaking, earthquakes, and artificial slope cutting, which, under the influence of gravity, cause landslides by sliding downhill along certain weak surfaces or zones, either as a whole or in scattered areas.

[0003] Existing slope deformation monitoring methods mostly use equipment such as levels and total stations to monitor slope deformation. However, these devices are easily damaged and have a short service life, which can lead to problems such as untimely early warning when slope deformation occurs.

[0004] Therefore, it is necessary to design a practical and effective monitoring device for slope softening. Utility Model Content

[0005] The purpose of this invention is to provide a monitoring device for slope softening to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a monitoring device for slope softening, comprising a main body, a gear rod connected to an internal bearing of the main body, a connecting rod connected to an internal bearing of the main body, a support frame connected to the top end of the gear rod, a middle end of the support frame being connected to the connecting rod by bearings, a pressure plate being provided above the support frame, and a telescopic plate being provided above the main body, the extended end of the telescopic plate being connected to the pressure plate.

[0007] According to the above technical solution, a sliding groove is provided on the upper part of the main body, a first detector is provided inside the main body, a sliding block is provided on the inner side of the main body, and a rack is slidably connected inside the sliding block, with the rack meshing with a gear rod.

[0008] According to the above technical solution, a detection cylinder is fixedly installed at the top of the rack, a detection rod is slidably connected inside the detection cylinder, a first spring is welded to the bottom of the detection rod, the other end of the first spring is welded to the bottom of the detection cylinder, and a detection plate is fixedly installed at the top of the detection rod.

[0009] According to the above technical solution, a detection groove is provided on the upper part of the main body, a second detector is provided at the bottom of the detection groove, and a first trigger is provided on the outer side of the detection rod.

[0010] According to the above technical solution, a support plate is slidably connected to the upper part of the main body, a collection groove is provided at the end of the support plate, a support block is provided inside the main body, a guide rod is provided on the inner side of the support block, a second spring is provided on the outer side of the guide rod, a slider is slidably connected to the outer side of the guide rod, the slider is fixedly connected to the support plate, and the right side of the slider is welded to the second spring.

[0011] According to the above technical solution, a second trigger is provided at the bottom of the slider, and a third detector is provided at the bottom of the support block.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) By installing a pressure plate, the main body is driven into the foundation before the slope is monitored. The main body is monitored inside the slope soil to prevent external wear and tear that could damage the monitor. Under normal circumstances, the telescopic plate extends and retracts, with the pressure plate located on the far left of the main body and inside the slope. The telescopic plate prevents soil from falling into the inner side of the main body. When the slope softens, the soil will become unstable and move downwards. At this time, the soil above the slope will slide down due to gravity, thus pushing the pressure plate to the lower right. The support frame will be pushed and slide to the lower right along with the pressure plate. Pulled by the connecting rod, the gear rod rotates around the support point while the pressure plate remains horizontal. This allows the pressure plate to follow the softening displacement of the slope soil without changing its angle. The support frame slides in the sliding groove, which is surrounded by protective rubber to prevent soil from falling from the groove gaps into the inner side of the main body. The rubber is also stretchable and will not affect the displacement of the support frame. When the support frame touches the first detector, it means that the support frame has moved from the leftmost end to the rightmost end of the sliding groove, indicating that the slope is severely softened. Staff will be notified to conduct an on-site inspection.

[0014] (2) By setting up a detection plate, the detection plate is also located inside the slope. When the slope soil is constructed, it will press down on the detection plate, causing it to drive the detection rod to compress the first spring and place it inside the detection cylinder. Under normal tightness, it will continue to press down on the detection plate. When the detection plate can no longer press down on the first spring, causing it to rebound and drive the detection plate to rise through the detection rod, it indicates that the slope soil has softened. When the upper slope softens, it will slowly affect the middle section of the slope soil, causing it to soften as well. At this time, it is necessary to appropriately reduce the rebound force of the first spring to prevent the detection plate with rebound force from accelerating the destruction of the middle section of the slope soil structure. Therefore, when the rack descends, it will drive the detection cylinder to descend together. At this time, the rebound force of the first spring will be reduced.

[0015] (3) By setting up a collection trough, when the soft soil of the top or middle section of the slope softens, the outer layer of soil will fall and slide down. At this time, the soil will fall into the collection trough. As more soil accumulates inside, the weight of the collection trough increases, which will drive the slider to slide down on the guide rod and compress the second spring at the same time, so as to detect the overall softening degree of the slope.

[0020] 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.

[0021] Please see Figure 1-3This utility model provides a technical solution: a monitoring device for slope softening, comprising a main body 1, a gear rod 2 connected to an internal bearing of the main body 1, a connecting rod 3 connected to an internal bearing of the main body 1, a support frame 4 connected to the top bearing of the gear rod 2, a bearing connection between the middle end of the support frame 4 and the connecting rod 3, a pressure plate 5 disposed above the support frame 4, and a telescopic plate 7 disposed above the main body 1, the extended end of the telescopic plate 7 being connected to the pressure plate 5. The main body 1 is driven into the foundation before slope monitoring, and the monitoring is performed while the main body 1 is inside the slope soil, preventing external natural wear from affecting the monitoring. When the device is damaged, the telescopic plate 7 extends and retracts under normal circumstances. The pressure plate 5 is located on the far left of the main body 1 and inside the slope. The telescopic plate 7 can prevent soil from falling to the inside of the main body 1. When the slope softens, the soil will not be stable and will move downward. At this time, the soil above the slope will slide down due to gravity, thus pushing the pressure plate 5 to the lower right. The support frame 4 will slide to the lower right following the pressure plate 5 due to the thrust. Due to the pull of the connecting rod 3, the gear rod 2 rotates around the support point. At the same time, the pressure plate 5 remains horizontal, thus realizing that the pressure plate 5 can follow the slope soil softening displacement without changing the angle.

[0022] A sliding groove 6 is provided on the top of the main body 1. A first detector 25 is provided inside the main body 1. A sliding block 8 is provided on the inner side of the main body 1. A rack 9 is slidably connected inside the sliding block 8. The rack 9 is meshed with the gear rod 2. The support frame 4 slides in the sliding groove 6. The sliding groove 6 is surrounded by protective rubber to prevent soil from falling from the gaps in the sliding groove 6 to the inner side of the main body 1. At the same time, the rubber can be pulled without affecting the displacement of the support frame 4. When the support frame 4 touches the first detector 25, it means that the support frame 4 has moved from the leftmost end to the rightmost end of the sliding groove 6, indicating that the slope is seriously soft. Staff will be notified to conduct an on-site investigation. At the same time, when the gear rod 2 rotates, it will drive the rack 9 to move down through the gear, which will change the subsequent detection.

[0023] A detection cylinder 11 is fixedly installed at the top of the rack 9. A detection rod 12 is slidably connected inside the detection cylinder 11. A first spring 13 is welded to the bottom of the detection rod 12, and the other end of the first spring 13 is welded to the bottom of the detection cylinder 11. A detection plate 14 is fixedly installed at the top of the detection rod 12. The detection plate 14 is also located inside the slope. During the construction of the slope, the soil will press down on the detection plate 14, causing it to drive the detection rod 12 to compress the first spring 13, thus placing it inside the detection cylinder 11. Under normal tightening conditions, it will continue to press down. When the detection plate 14 can no longer press down on the first spring 13, causing it to rebound and drive the detection plate 14 to rise through the detection rod 12, it indicates that the slope soil has softened. When the upper slope softens, it will slowly affect the soil in the middle section of the slope, causing it to soften as well. At this time, it is necessary to appropriately reduce the rebound force of the first spring 13 to prevent the detection plate 14 with rebound force from accelerating the destruction of the soil structure in the middle section of the slope. Therefore, when the rack 9 descends, it will drive the detection cylinder 11 to descend together, and at this time the rebound force of the first spring 13 will be reduced.

[0024] A detection groove 10 is provided on the top of the main body 1, a second detector 16 is provided at the bottom of the detection groove 10, and a first trigger 15 is provided on the outside of the detection rod 12. When the soil softens and causes the first spring 13 to rebound and drive the detection plate 14 to rise, the first trigger 15 on the detection rod 12 will touch the second detector 16, indicating that the soil in the middle section of the slope is severely softened at this time, and the staff will be notified to conduct an on-site inspection.

[0025] A support plate 21 is slidably connected to the top of the main body 1. A collection groove 22 is provided at the end of the support plate 21. A support block 17 is provided inside the main body 1. A guide rod 18 is provided on the inner side of the support block 17. A second spring 19 is provided on the outer side of the guide rod 18. A slider 20 is slidably connected to the outer side of the guide rod 18. The slider 20 is fixedly connected to the support plate 21. The right side of the slider 20 is welded to the second spring 19. When the soft soil of the top or middle section of the slope softens, the outer layer of soil will fall and slide down. At this time, the soil will fall into the collection groove 22. As more soil accumulates inside, the weight of the collection groove 22 increases. At this time, it will drive the slider 20 to slide down on the guide rod 18, while compressing the second spring 19, so as to detect the overall softening degree of the slope.

[0026] The bottom of the slider 20 is equipped with a second trigger 23, and the bottom of the support block 17 is equipped with a third detector 24. When the slider 20 continues to slide down and the second trigger 23 touches the third detector 24, it means that there is too much soil in the collection tank 22 and the overall surface of the slope is severely softened. At this time, the staff will be notified to conduct an on-site investigation.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
