Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated detection device technology, and in particular to an automated slope detection device. Background Technology
[0002] my country is one of the countries in the world most severely affected by geological disasters. In recent years, affected by extreme weather and strong earthquakes, geological disasters in my country have become more frequent and prone to occur. Therefore, effective monitoring and early warning of geological disasters, especially landslides, is crucial for minimizing direct economic losses and casualties.
[0003] Currently, automated slope monitoring devices are commonly used for geological testing. These devices collect data on slope surface displacement, internal displacement, crack changes, groundwater levels, and rainfall by deploying various types of sensors on and around the slope. Through real-time, continuous, and high-precision data acquisition and analysis, the stability, deformation characteristics, and potential risks of the slope are dynamically monitored. The main purpose of slope surface displacement detection is to detect the risk of landslides, cracks, or collapses. Commonly used sensors for slope surface displacement detection include wire-type displacement sensors and laser sensors. Wire-type displacement sensors measure displacement changes at monitoring points on the slope surface by pulling and retracting a steel wire rope. However, the wire in wire-type sensors is exposed to the natural environment and is susceptible to the effects of severe weather such as wind, rain, snow, and hail, or contamination from dust, oil, and chemicals. This can cause the rope surface to adhere to substances, reduce its strength, and become damaged, severely affecting the measurement accuracy. Similarly, laser sensors are also susceptible to the effects of natural conditions such as rainfall, wind, and changes in temperature and humidity, interfering with the accuracy of the data collected during slope monitoring.
[0004] Therefore, this application provides an automated slope detection device to solve the problems mentioned in the background art. Utility Model Content

[0009] A further improvement of the present invention is that the support includes a flat plate, the left half of the flat plate body is fixed to the bottom inner wall of the second square tube, the right half of the flat plate extends out of the second square tube and is suspended in the air, and a door-shaped vertical plate is provided on the front side of the right half of the flat plate near the right side.
[0010] A further improvement of this utility model is that: four elongated holes are evenly arranged on the left half of the flat plate body, and bolt posts are installed inside the elongated holes. The bolt posts are located on the upper surface of the bottom surface of the second square tube end.

[0030] The present invention will be further explained below with reference to specific embodiments.
[0031] like Figures 1-7As shown, the automated slope detection device provided in this embodiment includes: 1. An automated slope detection device, characterized in that it includes a first column 1, which is vertically installed at the top of the slope, and a first square tube 11 is installed on the side of the lower part of the first column 1; the first square tube 11 is parallel to the slope surface; a second column 2 is vertically installed on the slope or at the bottom of the slope; a second square tube 21 is installed on the opposite side of the second column 2 and the first column 1; the first square tube 11 is fitted with the second square tube 21, and a bracket 3 is fixed to the end edge of the second square tube 21 located inside the first square tube 11. An encoder 4 is installed on the bracket 3, and an encoding wheel 5 is installed on the mechanical shaft of the encoder 4. The wheel surface of the encoding wheel 5 abuts against the inner wall of the bottom surface of the second square tube 21. The encoding wheel 5 is used to measure the sliding displacement of the second square tube 21 inside the first square tube 11, thereby reflecting the displacement of the slope surface. This automated slope detection device employs a nested design of a first square tube 11 and a second square tube 21. Slope displacement is transmitted through the sliding of the second square tube 21. The structure is simple and highly resistant to wind interference, ensuring that displacement measurement is synchronized with slope deformation. Combined with the mechanical transmission design of the encoder 4 and the encoder wheel 5, it significantly improves the accuracy and anti-interference capability of slope surface displacement monitoring. The encoder wheel 5 directly abuts against the inner wall of the second square tube 21, converting the slope displacement into a mechanical shaft rotation signal from the encoder. This avoids the wear, contamination, or breakage problems caused by exposed pull ropes in traditional wire-type sensors, while also mitigating the susceptibility of laser sensors to interference from rainfall, temperature, and humidity. The nested structure of the first square tube 11 and the second square tube 21 provides physical protection for the internal components, effectively isolating them from wind, sand, rain, and chemical corrosion, ensuring long-term stable operation, higher measurement accuracy, and more reliable data.
[0032] like Figure 1 As shown, in this embodiment, the first column 1 includes a horizontal base plate 6, which is fixed to a cement pile by bolts. A first vertical pipe 12 is installed on the base plate 6, and a first square pipe 11 is installed on the side of the first vertical pipe 12. Reinforcing ribs 7 are provided on the upper and lower connecting surfaces of the first square pipe 11 and the first vertical pipe 12. A control box 14, a solar panel 15, and a GNSS Beidou receiver 16 are installed on the first vertical pipe 12 from bottom to top. The control box 14, the solar panel 15, and the GNSS Beidou receiver 16 are all existing equipment and will not be described in detail here. The second column 2 includes a horizontal base plate 6, which is fixed to a cement pile by bolts. A second vertical pipe 22 is installed on the base plate 6, and a second square pipe 21 is installed on the opposite side of the second vertical pipe 22 and the first vertical pipe 12. Reinforcing ribs 7 are provided on the upper and lower connecting surfaces of the second square pipe 21 and the second vertical pipe 22. Both the first column 1 and the second column 2 are fixed to the cement piles by the horizontal base plate 6. Combined with the reinforcement of the reinforcing ribs 7, the stability of the overall structure is ensured, enabling it to withstand complex on-site environmental conditions. The control box 14, solar panel 15, and GNSS Beidou receiver 16 integrated on the first column not only realize the automation of slope monitoring but also ensure real-time data transmission and accurate positioning.
[0033] like Figure 1 As shown, in this embodiment, the support 3 includes a flat plate 31. The left half of the flat plate 31 is fixed to the inner wall of the bottom of the second square tube 21. The right half of the flat plate 31 extends out of the second square tube 21 and is suspended. A door-shaped vertical plate 33 is provided on the front side of the right half of the flat plate 31 near the right side. Four elongated holes 32 are evenly arranged on the left half of the flat plate 31. Bolt posts 23 are installed inside the elongated holes 32 and are located on the upper surface of the bottom surface of the second square tube 21. Bolts are bolted to the bolt posts 23 to fix the flat plate 31. The left half of the flat plate 31 cooperates with the bolt posts 23 through the elongated holes 32 to achieve adjustable fixation of the support 3 on the second square tube 21, allowing for fine longitudinal position adjustment along the direction of the elongated holes 32, providing extended support for the suspended right half of the flat plate 31, and avoiding interference with the rotation of the encoding wheel 5. The vertical plate 33 is gate-shaped, with a shaft hole 34 at its upper part. Several mounting holes 35 are located around the outer periphery of the shaft hole 34. An encoder 4 is mounted on one side of the vertical plate 33, adjacent to the flat plate 31. The encoder 4 is fixed by bolts that fit into the mounting holes 35. The mechanical shaft of the encoder 4 passes through the shaft hole 34 and is fitted at its end into the center hole of the encoder wheel 5. An encoder wire 41 is mounted on the encoder 4, coiled inside the first square tube 11. A wire outlet hole 13 is provided on the side wall of the first square tube 11 near the first vertical tube 12. The encoder wire 41 exits through the wire outlet hole 13 and connects to the control box 14. When the slope surface displaces, causing the second square tube 21 to move, the encoder fixed to the second square tube 21 moves accordingly. The coiled spiral releases its length when stretched, ensuring continuous transmission of the displacement signal and preventing cable breakage.
[0034] In this embodiment, the present invention also provides the working principle of the automated slope detection device: when the slope surface is displaced, the second column 2 fixed on the slope or at the bottom of the slope moves with the slope. The movement of the second column 2 drives the second square tube 21 to move away from the first square tube 11 inside the first square tube 11. The movement of the second square tube 21 drives the encoder 4 fixed at the end edge to move. The movement of the encoder 4 causes the encoder wheel 5 to rotate on the first square tube 11. At the same time, the spiral encoder wire 41 coiled inside the first square tube 11 is stretched. The encoder wire 41 is connected to the control box 14. The control box 14 is equipped with a data acquisition module, a communication module, a storage and power supply control module, which are electrically connected to the solar panel 15, the GNSS Beidou receiver 16 and the encoder wire 41, respectively, to collect, transmit, process and store the slope displacement signal, so as to monitor the slope displacement change in real time.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
