[0022] The formation of geological hazards in reservoir areas is closely related to the drastic changes in hydrological conditions during reservoir operation. In the early stages of impoundment, the periodic rise and fall of the reservoir water level has a significant softening, seepage pressure, and stress redistribution effect on the riverbank soil and rock, easily inducing landslides, collapses, and other disasters. For example, since the Three Gorges Reservoir began impounding water, the annual water level fluctuation has reached tens of meters, leading to the deterioration of the riverbank rock structure and the formation of multiple potential sliding zones. These types of hazards are characterized by their high degree of concealment and suddenness, often erupting in concentrated bursts after heavy rainfall or rapid water level changes, threatening the safety of riverside settlements, waterways, and infrastructure.

[0023] Early monitoring of geological hazards in the reservoir area relied primarily on manual patrols and measurements using simple instruments. Community-based monitoring and prevention personnel visually observed macroscopic phenomena such as surface cracks and building deformations, combining this with simple equipment like displacement stakes and rain gauges for recording. However, this method had significant drawbacks: firstly, manual patrols could not cover the vast reservoir area, especially in areas with rugged terrain, limiting the frequency and timeliness of monitoring; secondly, traditional instruments lacked accuracy, such as mechanical inclinometers, which were less capable of capturing minute deformations, and data recording relied on manual transcription, easily leading to the omission of crucial information. For instance, in the monitoring of the Lianziya unstable rock mass in the Three Gorges Reservoir area, early warnings of large-scale rock mass displacements were missed due to insufficient equipment sensitivity.

[0024] With the integration of IoT, remote sensing, and AI technologies, a comprehensive "space-air-ground" system is gradually being established for geological disaster monitoring in reservoir areas. Satellite remote sensing technologies such as InSAR (Inductive Aperture Radar Interferometry) enable millimeter-level monitoring of surface deformation in reservoir areas, identifying slow displacement trends over a wide area and providing support for early detection. The ground monitoring network consists of GNSS receivers, crack gauges, pore water pressure sensors, etc., transmitting data via 4G / 5G or BeiDou satellite communication. For example, the universal monitoring instruments deployed by the Wuhan Geological Survey Center in the Three Gorges Reservoir area integrate rain gauges, moisture content monitors, GNSS modules, etc., and achieve long-term stable operation through low-power design.

[0025] Structural innovation in monitoring equipment has become a key breakthrough. Traditional monitoring devices often suffer from short circuits or mechanical failures due to the high humidity and corrosive environment of reservoir areas. Modern equipment adopts a modular design, such as a detachable base and protective cover structure, which facilitates rapid deployment and maintenance in complex terrains. Some devices integrate solar power systems, combined with energy storage batteries, to solve the power supply problems in remote areas. For example, a certain type of slope stability detection radar uses a circular arc synthetic aperture architecture, achieving full-coverage monitoring through rotating scanning, unaffected by vegetation obstruction. Its ultra-lightweight and portable design allows for deployment within minutes, meeting the needs of emergency rescue.

[0026] The core of current early warning systems lies in multi-source data fusion and intelligent analysis. Sensor networks collect parameters such as surface displacement, groundwater level, and rainfall in real time, perform preliminary processing through edge computing nodes, and then transmit the data to the data center via a communication network. The platform layer uses GIS technology to achieve spatial visualization of monitoring data and constructs geological disaster evolution models by combining historical data. For example, one system uses machine learning algorithms to analyze the correlation between displacement rate and rainfall to establish landslide imminent warning thresholds.

[0027] However, existing technologies still face challenges. The reservoir area has complex geological conditions, with significant differences in lithology and hydrological parameters across different regions, making it difficult for general models to accurately adapt to all scenarios. Furthermore, communication disruptions during extreme weather can lead to data loss, affecting the timeliness of early warnings. While the collaborative mechanism between community-based monitoring and professional monitoring has proven effective in the Three Gorges Reservoir area, the technical skills of community monitors vary considerably, necessitating standardized training and the use of smart terminals to improve overall efficiency.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1 to 4 As shown, this embodiment provides a reservoir area geological disaster early warning device, including a monitoring box 1. The monitoring box 1 is equipped with a monitoring mechanism. A first connecting column 2 is fixed to the bottom surface of the monitoring box 1. Multiple reinforcement mechanisms are provided at equal intervals on the outer side of the bottom of the first connecting column 2. The reinforcement mechanism includes a first groove 3 set on the outer side of the first connecting column 2. A reinforcement anchor 4 is provided in the first groove 3. One end of a connecting rope 5 is fixed to the top of the reinforcement anchor 4. The other end of the connecting rope 5 is located in the first connecting column 2. A limiting part is provided in the first groove 3, and the limiting part is adapted to the reinforcement anchor 4.

[0031] When the device is placed in the area to be monitored in the reservoir, the reinforcing anchor 4 is first removed from the first groove 3 and inserted into the soil or rock mass, penetrating deep into stable strata; the connecting rope 5 at the top of the reinforcing anchor 4 extends along the inside of the first connecting column 2 to prevent the anchor from retracting or shifting; the monitoring mechanism inside the monitoring box 1 is simultaneously activated to begin collecting geological environmental data. This invention, through the combined structure of "anchor 4 + connecting rope 5," achieves a firm anchoring of the device to the geological body, solving the problem of easy displacement of traditional devices on loose soil or slopes in the reservoir area; the reinforcing anchor 4 enhances the overall structure's resistance to sliding and overturning.

[0032] In a further optimized design, a first connecting seat 6 is fixedly connected in the first groove 3, and a second groove 7 is provided at one end of the first connecting seat 6 near the reinforcing anchor rod 4. The second groove 7 is adapted to the reinforcing anchor rod 4.

[0033] The first connecting seat 6 is used to position the anchor rod 4 during transportation to prevent the anchor rod 4 from swaying back and forth.

[0034] The scheme is further optimized. The limiting part includes a second connecting seat 8 and a third connecting seat 9 that are respectively fixed to both sides of the first connecting seat 6. The second connecting seat 8 has a third groove 10 on the side near the reinforcing anchor rod 4. One end of the limiting rod 11 is rotatably connected in the third groove 10. The other end of the limiting rod 11 is fixed to a fourth connecting seat 12. A limiting element is provided between the fourth connecting seat 12 and the third connecting seat 9.

[0035] The limiting rod 11 further limits the reinforcing anchor rod 4 to prevent it from shaking during transportation.

[0036] In a further optimized design, the limiting component includes a fourth groove 13 located within the third connecting seat 9. The fourth groove 13 is situated on the side of the third connecting seat 9 closest to the fourth connecting seat 12. A flexible limiting rod 14 is fixedly connected to the side of the fourth connecting seat 12 closest to the fourth groove 13. A limiting hook 15 is provided at one end of the flexible limiting rod 14 closest to the fourth connecting seat 12. A first connecting plate 16 is fixedly connected within the fourth groove 13. The limiting hook 15 abuts against the first connecting plate 16. A first connecting rod 17 is slidably connected to the side of the first connecting plate 16 furthest from the fourth connecting seat 12. One end of the first connecting rod 17 extends to the outside of the fourth groove 13, and the top of the first connecting rod 17 abuts against the limiting hook 15.

[0037] In a further optimized design, the first connecting plate 16 is provided with a first sliding groove 18 on the side near the first connecting rod 17 and the fourth groove 13 is provided with a first sliding groove 18 on the side near the first connecting rod 17. Slider 19s are symmetrically fixed to both sides of the first connecting rod 17. The slider 19 and the adjacent first sliding groove 18 are slidably connected. A first spring 20 is provided between the bottom of the slider 19 and the first sliding groove 18.

[0038] When it is necessary to limit the reinforcing anchor rod 4 in the first groove 3, the limiting rod 11 rotates, so that the fourth connecting seat and the third connecting seat 9 are in contact. At the same time, the flexible limiting rod 14 enters the fourth groove 13, and the limiting hook 15 abuts against the first connecting plate 16 to limit the fourth connecting seat 12. When it is necessary to release the limit, press the first connecting rod 17 towards the side close to the limiting hook 15 to move the limiting hook 15 away from the first connecting plate 16, release the limit of the fourth connecting seat 12, and take out the fixed anchor rod.

[0039] In a further optimized design, a connecting ring 21 is provided at the top of the first groove 3. The connecting ring 21 is connected to the first connecting post 2, and the connecting rope 5 is located inside the connecting ring 21.

[0040] The connecting rope 5 is threaded inside the connecting ring 21 to avoid direct friction with the edge of the first groove 3. Simultaneously, the connecting ring 21 guides the direction, ensuring that the connecting rope 5 extends orderly along the inside of the first connecting post 2. The connecting ring 21 reduces wear on the connecting rope 5, extending its service life; it also guides the direction of the connecting rope 5, preventing it from tangling or getting stuck during deployment and retraction.

[0041] In a further optimized design, a first cavity 22 is provided inside the first connecting column 2. Multiple take-up and release mechanisms are provided at equal intervals inside the first cavity 22. Each take-up and release mechanism includes a second connecting plate 23 fixedly connected inside the first cavity 22. A first motor 24 is fixedly connected to the top surface of the second connecting plate 23. A connecting roller 25 is fixedly connected to the output shaft of the first motor 24. A connecting rope 5 is wound around the connecting roller 25.

[0042] The first motor 24 drives the connecting roller 25 to rotate forward, and the connecting rope 5 is wound around the connecting roller 25 to tighten and reinforce the anchor rod 4; when it is necessary to loosen the anchor rod, the motor reverses, the connecting rope 5 is released, and the insertion depth of the reinforced anchor rod 4 can be adjusted.

[0043] The scheme is further optimized. The monitoring mechanism includes a third connecting plate 26 fixed in the monitoring box 1. The top surface of the third connecting plate 26 is provided with an angle sensor 27 and an acceleration sensor 28, respectively. The bottom surface of the third connecting plate 26 is provided with a controller 29, which is electrically connected to the angle sensor 27 and the acceleration sensor 28, respectively.

[0044] The tilt sensor 27 monitors the change in the tilt angle of the device, and the acceleration sensor 28 monitors the displacement acceleration of the device. The controller receives the sensor data, and when the tilt angle or acceleration exceeds a preset threshold, it determines it as a precursor to a geological disaster and triggers an early warning. Multi-parameter (tilt, acceleration) fusion monitoring improves the accuracy of identifying disasters such as landslides and collapses.

[0045] To further optimize the scheme, the monitoring mechanism also includes a battery 30 installed at the bottom of the monitoring box 1, and a photovoltaic module 31 installed on the top surface of the monitoring box 1. The photovoltaic module 31 is electrically connected to the battery 30 through an inverter.

[0046] The photovoltaic module 31 converts light energy into electrical energy, which is then stored in the battery 30 via an inverter. The battery 30 supplies power to the monitoring mechanism, controller 29, and retraction mechanism, ensuring the long-term operation of the device.

[0047] To further optimize the design, a rain sensor 32 is installed on the top surface of the monitoring box 1, and the rain sensor 32 is electrically connected to the controller 29.

[0048] Rainfall sensor 32 monitors rainfall data in real time and transmits it to controller 29; controller 29 combines data such as tilt angle and acceleration to comprehensively judge the impact of rainfall on the geological body.

[0049] The combined structure of the reinforcing anchor 4 and the connecting rope 5, along with the multiple locking mechanisms of the limiting part, ensures the long-term stability of the device in complex terrain (such as slopes and loose soil) in the reservoir area. The launching and retracting mechanism drives the connecting roller 25 through the first motor 24 to dynamically adjust the tension of the reinforcing anchor 4 to adapt to geological deformation or water level rise and fall. The multi-parameter integrated monitoring of tilt angle, acceleration, and rainfall, and the controller 29 analyzes the data in real time to improve the accuracy and timeliness of disaster identification. The combination of photovoltaic module 31 and battery 30 solves the power supply problem in remote reservoir areas and ensures the long-term operation of the device.
