Description

Technical Field

[0001] This utility model relates to the field of landslide monitoring technology, and in particular to an early warning device for landslide displacement monitoring. Background Technology

[0002] Landslides refer to the phenomenon where soil or rock masses on a slope slide downwards, either entirely or partially, along a weak surface or zone, under the influence of gravity due to various factors such as river erosion, groundwater activity, rainwater soaking, earthquakes, and artificial slope cutting. Landslides are a common geological hazard, often closely related to multiple factors, and pose a serious threat to industrial and agricultural production, the safety of people's lives and property, and infrastructure such as transportation and water conservancy. However, most existing monitoring stations use wire-type or laser-type displacement sensors to monitor landslide displacement. These methods are easily limited by adverse weather conditions such as rain and fog, and are unsuitable for landslides with trees; they lack automatic alarm functions, resulting in limited functionality; they are inconvenient for monitoring with obvious reference points, and cannot monitor rainfall in real time, offering only limited monitoring capabilities.

[0003] Therefore, an early warning device for landslide displacement monitoring is proposed. Utility Model Content

[0024] 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.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-2This utility model provides an early warning device for landslide displacement monitoring, comprising:

[0027] Monitoring pile 2, with its bottom embedded in the slope; monitoring pile 2 is equipped with a piezoelectric rain gauge 1, a photovoltaic power generation system, an audible and visual alarm and a night vision camera 5.

[0028] Tension sensor 11 is installed on the inner wall of monitoring pile 2;

[0029] The displacement monitoring mechanism includes a flexible hose 15, a displacement block 16, a fixed pulley assembly, and a stainless steel rope 17. One end of the flexible hose 15 is fixedly connected to the displacement block 16, and the other end is connected to the monitoring pile 2. One end of the stainless steel rope 17 is fixedly connected to the displacement block 16, and the other end is fixedly connected to the tension sensor 11. The flexible hose 15 is sleeved on the stainless steel rope 17, and the stainless steel rope 17 is wound around the fixed pulley assembly. The displacement block 16 is pre-embedded inside the landslide.

[0030] The control system is installed on the monitoring pile 2; the piezoelectric rain gauge 1, photovoltaic power generation system, audible and visual alarm, night vision camera 5 and tension sensor 11 are all electrically connected to the control system.

[0031] With this configuration, the present invention effectively avoids the limitations of adverse weather conditions such as rain and fog by pre-burying the flexible hose 15, displacement block 16, fixed pulley assembly and stainless steel rope 17 inside the landslide, and by installing the tension sensor 11 inside the monitoring pile 2, and by using this configuration. When the landslide location begins to move slowly and slightly, it moves the displacement block 16 together. The tension sensor 11 is pulled by the displacement block 16 and transmits the monitoring signal to the control system. After receiving the signal, the control system promptly controls the audible and visual alarm to issue an alarm signal. The timely alarm signal can help nearby residents evacuate quickly and avoid casualties. At the same time, it prompts the staff to take countermeasures, which enhances the functionality of the device.

[0032] This invention, by installing a piezoelectric rain gauge 1 on the top of the monitoring pile 2, allows the control system to automatically issue an early warning signal when the rainfall reaches or exceeds a certain threshold, reminding relevant personnel to take preventive measures to reduce the occurrence and losses of landslide disasters; at the same time, combined with the night vision camera 5, it can monitor the geology in real time, increasing the diversity of landslide displacement monitoring and effectively improving the response speed of the early warning.

[0033] This invention effectively ensures the safety of the monitoring equipment and reduces economic losses by burying the monitoring pile 2 in a stable geological structure. The photovoltaic power generation system in this invention can provide clean energy for the device, reduce operating costs, and is conducive to environmental protection and sustainable development.

[0034] The scheme is further optimized. The fixed pulley assembly includes a first fixed pulley 13 and a second fixed pulley 18. The first fixed pulley 13 is installed on the inner side wall of the bottom of the monitoring pile 2, and the second fixed pulley 18 is installed inside the hose 15. The stainless steel rope 17 is wound around the first fixed pulley 13 and the second fixed pulley 18.

[0035] This configuration, with the stainless steel rope 17 wound around the first fixed pulley 13 and the second fixed pulley 18, ensures that the stainless steel rope 17 remains vertical inside the monitoring pile 2, guaranteeing that the tension sensor 11 can more accurately reflect the actual tension and improving the reliability of the monitoring data. Furthermore, the rolling contact between the outer edges of the first fixed pulley 13 and the second fixed pulley 18 and the stainless steel rope 17 allows for easy switching of the rope's force direction without changing the magnitude of the force. This also avoids direct friction between the stainless steel rope 17 and the inner wall of the monitoring pile 2, extending the service life of the stainless steel rope 17.

[0036] The scheme is further optimized. The control system includes an equipment box 8, which is installed on the monitoring pile 2. The equipment box 8 contains a battery 9, a controller 6, and a wireless transmission module 10. The photovoltaic power generation system is electrically connected to the battery 9. The battery 9, the wireless transmission module 10, the piezoelectric rain gauge 1, the audible and visual alarm, the night vision camera 5, and the tension sensor 11 are all electrically connected to the controller 6.

[0037] The controller 6 can be configured according to the specific usage environment. For example, it can be controlled by a microcontroller or by a PLC, ARM (Advanced RISC Machine), FPGA (Field-Programmable Gate Array), etc. This embodiment does not make specific limitations.

[0038] The scheme is further optimized. The sound and light alarm includes a warning light 3 and a speaker 4. Both the warning light 3 and the speaker 4 are electrically connected to the controller 6. In this embodiment, the warning light 3 is made of ultra-long life LED, which has high luminous efficiency, long life, energy saving and environmental protection. The sound alarm intensity of the speaker 4 is as high as 115 decibels or more, with strong penetrating ability, which can effectively help nearby residents evacuate quickly and avoid casualties.

[0039] To further optimize the design, the tension sensor 11 is mounted on the inner wall of the monitoring pile 2 via a support rod 12.

[0040] The design was further optimized by providing a window 14 at the bottom of the side wall of monitoring pile 2, through which a stainless steel rope 17 extends into monitoring pile 2.

[0041] The scheme is further optimized. The photovoltaic power generation system includes photovoltaic solar panels 7, inverters (not shown in the figure) and photovoltaic brackets. The photovoltaic brackets are installed on monitoring piles 2, and the photovoltaic solar panels 7 and inverters (not shown in the figure) are installed on the photovoltaic brackets. The photovoltaic solar panels 7 are electrically connected to the storage battery 9 through the inverters (not shown in the figure).

[0042] This setup provides clean energy for the device, reduces operating costs, and is beneficial to environmental protection and sustainable development.

[0043] Further optimization of the scheme involves fixing the bottom of monitoring pile 2 to a deep pit (not shown in the figure) by pouring concrete (not shown in the figure), which can improve the stability of monitoring pile 2, thereby ensuring the safety of the monitoring equipment on monitoring pile 2 and reducing economic losses.
