Description

Technical Field

[0001] This utility model relates to the field of flood control monitoring technology in water conservancy projects, and in particular to an automatic flood control detection device for river embankments, which is suitable for automatic detection of river embankments and riverbanks with serious soil erosion. Background Technology

[0002] River embankments are susceptible to erosion after heavy rainfall, and their generally steep slopes make them high-risk areas for soil erosion, posing a continuous threat to the lives and property of people living along the river. Therefore, continuous and accurate monitoring of various parameters of river embankments, such as soil properties, water level, and water flow velocity, as well as timely flood risk prediction, are of great significance for flood prevention and disaster reduction efforts.

[0003] Currently, monitoring of riverbanks relies heavily on a combination of traditional manual sampling and fixed-point measurement using single sensors, which suffers from low efficiency, limited coverage, and poor real-time performance. Although some automated equipment has been applied to the field of water conservancy monitoring, such as the Chinese patent CN118749356A which proposes a method for constructing flood-control vegetation based on multi-parameter survey data such as soil pH, texture, and groundwater level, this method still relies on manual on-site sampling and data analysis. It has not achieved true full-process automation, multi-sensor integration, and intelligent prediction, and in particular, it lacks the ability to adapt to complex terrain conditions and the ability to fuse and process multi-source heterogeneous data in real time.

[0004] In addition, existing detection devices are often loosely structured and have limited functions, making it difficult to work stably and for a long time in harsh environments such as embankment slopes and soft mud. They also lack effective self-powered and anti-collision and vibration-resistant mechanisms, resulting in difficulties in long-term deployment and insufficient data continuity, which makes it impossible to provide highly reliable and integrated data support for flood control decisions and vegetation configuration.

[0005] Therefore, how to automate soil sampling and high-frequency monitoring of multiple parameters while improving the adaptability and durability of equipment in complex environments, and how to introduce edge intelligence algorithms to achieve real-time prediction of flood risk and automatic generation of vegetation construction schemes, have become technical challenges that urgently need to be solved in this field. Utility Model Content

[0006] The purpose of this invention is to provide an automatic flood control detection device for river embankments, in order to solve the aforementioned technical problems existing in the prior art.

[0007] To achieve the above objectives, this utility model provides the following solution: an automatic flood control detection device for river embankments, comprising a device body with a walking mechanism, wherein the device body contains an automatic sampling unit, a navigation and communication module, a power supply, and a data acquisition and analysis unit, and a sampling port is opened at the bottom of the device body; the walking mechanism is located at the bottom of the device body and adopts a hybrid structure of tracks and Mecanum wheels; the automatic sampling unit includes a soil drilling component and a sampling component, which are mounted on the same rotating base, and the rotating base rotates to switch the soil drilling component and the sampling component to be aligned with the sampling port below; the data acquisition and analysis unit includes a groundwater detector, a pH detection module, a soil texture detection module, and a data analysis system.

[0008] Furthermore, the drilling assembly includes a rotary motor and a retractable metal drill bit.

[0009] Furthermore, a MEMS earth pressure sensor is also provided on one side of the retractable metal drill bit.

[0010] Furthermore, the sampling assembly includes a telescopic mechanism and a sampling ring cutter. The end of the sampling ring cutter is connected to a serrated sampling head. The two ends of the sampling ring cutter are detachably connected to the telescopic mechanism and the sampling head through an upper connecting buckle and a lower connecting buckle, respectively.

[0011] Furthermore, a first rotating mechanism is fixed above the sampling port. The first rotating mechanism is connected to a transverse cutter. The first rotating mechanism drives the transverse cutter to rotate in order to remove excess soil sample that has not entered the sampling ring.

[0012] Furthermore, the automatic flood control detection device applied to river embankments also includes a shock absorption mechanism located within the device body.

[0013] Furthermore, the shock absorption mechanism includes a carbon fiber protective frame, a foam buffer layer, and a rubber shock absorber.

[0014] Furthermore, the data acquisition and analysis unit also includes a flow detection radar and a flow detection camera.

[0015] Furthermore, the pH detection module is equipped with an optical fiber sensing probe, the surface of which is coated with a hydrophobic nano-coating and is equipped with an ultrasonic vibration module.

[0016] Furthermore, the device body is also equipped with a temperature control module, which incorporates a metal blower and a temperature sensor.

[0017] Compared with the prior art, the present invention discloses at least the following beneficial effects:

[0018] This invention utilizes a rotating base to drive the drilling and sampling components to switch between them, allowing them to share the same sampling port. Drilling is performed before sampling, completing the process in one integrated step, reducing equipment movement and borehole wall exposure time, and lowering the risk of slippage and borehole collapse. The rotary-telescopic composite drill bit can quickly penetrate miscellaneous fill soil, and the sidewall soil pressure sensor detects resistance in real time, stopping and automatically switching to sampling upon encountering a hard layer to avoid over-drilling. The sampling ring is directly connected to the telescopic mechanism via a connecting buckle, ensuring no thrust loss. The serrated sampling cutter head easily enters the soil, obtaining a complete soil sample. The transverse cutter cuts in one stroke, eliminating the need for manual trimming and ensuring that columnar soil samples are immediately delivered to the testing unit. This allows groundwater, pH, and texture data to be acquired simultaneously in the same microenvironment, directly improving the reliability of subsequent risk assessment.

Detailed Implementation

[0026] 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.

[0027] 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.

[0028] Reference Figures 1 to 5 As shown, this embodiment provides an automatic flood control detection device for river embankments. This device integrates automatic soil sampling, multi-parameter environmental monitoring, and edge intelligent analysis, and includes main components such as the device body, a walking mechanism 1, an automatic sampling unit 10, a data acquisition and analysis unit 5, an energy system, a shock absorption mechanism 14, and a navigation and communication module 4. The walking mechanism 1 is used for movement and positioning in complex terrain; the automatic sampling unit 10 is used to collect soil samples 100; the data acquisition and analysis unit 5 is used to perform multi-parameter detection and intelligent analysis on the collected soil samples 100; the energy system provides power to the device; the shock absorption mechanism 14 absorbs vibrations and impacts during movement; and the navigation and communication module 4 is used for path planning, positioning, and data transmission.

[0029] In this embodiment of the utility model, the walking mechanism 1 adopts a hybrid structure of track and Mecanum wheel. The track surface is provided with anti-slip texture and is equipped with an adjustable suspension system to adapt to complex terrains such as embankment slopes and soft mud, ensuring the stability and obstacle-crossing ability of the device during movement.

[0030] In this embodiment of the invention, the device body is provided with a shock absorption mechanism 14, which includes a carbon fiber protective frame, a foam buffer layer, and a rubber shock absorber. Specifically, the device body is provided with a carbon fiber protective frame for supporting and installing other structural components. The frame has a thickness of 5 mm and a tensile strength of 3.5 GPa. The edge of the carbon fiber protective frame is connected to the inner wall of the device body via a rubber shock absorber, and a foam buffer layer with a density of 30 kg / m³ is filled between them. This effectively absorbs vibrations and impacts during movement, protecting the internal precision components from damage.

[0031] In one specific embodiment, the walking mechanism 1 includes two sets of track and Mecanum wheel hybrid structures located on both sides of the bottom of the device. Each side structure includes four stainless steel wheels 11, one track, and two shock-absorbing springs 12. The surfaces of the four stainless steel wheels 11 are coated with a corrosion-resistant coating to enhance grip and stability on slippery surfaces. The shock-absorbing springs 12 are positioned between the stainless steel wheels 11 and the main body of the device, working in conjunction with the shock-absorbing mechanism 14 to further improve shock resistance.

[0032] In this embodiment of the invention, the automatic sampling unit 10 includes a drilling assembly 15, a sampling assembly 16, a first rotating mechanism 17, a second rotating mechanism 19, a third rotating mechanism 21, a transverse cutter 18, a sampling ring cutter 28, a sampling cutter head 30, a rotary motor 31, a retractable metal drill bit 32, and a MEMS soil pressure sensor 33. After the device is started, guided by the navigation and communication module 4, the walking mechanism 1 moves the device to the target detection area. Upon arrival, the rotary motor 31 drives the retractable metal drill bit 32 to rotate and extend downwards, penetrating deep into the soil. Simultaneously, the MEMS soil pressure sensor 33 detects the soil pressure in real time, with a range of 0 to 500 kPa. It is encapsulated in corrosion-resistant ceramic and tests the soil pressure by rotation before sampling to provide a reference for subsequent sampling. After drilling is completed, the transverse cutter 18, driven by the first rotating mechanism 17, cuts laterally into the soil. The sampling cutter head 30, under the coordinated action of the second rotating mechanism 19 and the third rotating mechanism 21, works with the sampling ring cutter 28 to complete the circumferential cutting and extraction of the soil sample. The sampling ring 28 is quickly connected and disconnected from the sampling component 16 via the upper connecting buckle 27 and the lower connecting buckle 29, facilitating the transfer of soil samples. The extracted soil sample 100 is transported via the first conveyor belt 23 to the stable environment created by the constant temperature module 24, where pH detection and texture analysis are performed sequentially.

[0033] In one specific embodiment, the drilling assembly 15 and the sampling assembly 16 are mounted on the same rotating base 13. The rotating base 13 is driven to rotate by a drive mechanism to switch the alignment of the drilling assembly 15 and the sampling assembly 16 with the sampling port below. In this embodiment, the device achieves switching by rotating the drilling assembly 15 and the sampling assembly 16 through the rotating base 13, allowing them to share the same sampling port. Drilling is performed first, followed by sampling, and the process is completed in one step, reducing equipment movement and borehole wall exposure time, and lowering the risk of slippage and borehole collapse.

[0034] In one specific embodiment, such as Figure 4 As shown, the sampling assembly 16 includes a telescopic mechanism 26, an upper connecting buckle 27, a sampling ring cutter 28, a lower connecting buckle 29, and a sampling head 30. The telescopic mechanism 26 is used to control the up and down movement of the sampling assembly 16 to achieve precise adjustment of the sampling depth; the upper connecting buckle 27 and the lower connecting buckle 29 are used to fix the two ends of the sampling ring cutter 28 respectively to ensure its stability and replaceability during the sampling process; the sampling head 30 is located at the bottom of the sampling ring cutter 28 and is used to cut into the soil and complete the collection of soil sample 100.

[0035] In one specific embodiment, such as Figure 5 As shown, the soil drilling assembly 15 includes a rotary motor 31, a retractable metal drill bit 32, and a MEMS soil pressure sensor 33. The rotary motor 31 provides rotational power, driving the retractable metal drill bit 32 to achieve a combined rotational and retractable motion to complete soil drilling; the MEMS soil pressure sensor 33 is integrated on one side of the drill bit to monitor the changes in soil pressure in real time during drilling, providing data support for determining soil compaction and sampling timing.

[0036] In one specific embodiment, the navigation and communication module 4 integrates GPS and wireless communication functions, with a positioning accuracy of ±0.1 meters, ensuring that the device accurately reaches the designated sampling point.

[0037] In this embodiment of the invention, the data acquisition and analysis unit 5 includes a groundwater detector 7, a pH detection module 2, a soil texture detection module 9, and a data analysis system. The data analysis system comprises a perception layer, an edge computing layer, and a communication layer. The edge computing layer is equipped with an embedded AI chip and a built-in LSTM neural network. By training with 100,000 sets of historical flood data, it achieves deep fusion and intelligent analysis of real-time monitoring data, not only assessing current flood risk but also predicting future trends and generating scientific and optimized flood-prevention vegetation construction plans. The communication layer adopts a dual-mode redundant backup design of LoRaWAN and 5G. LoRaWAN has a transmission distance of up to 3 kilometers, and 5G uses frequency hopping technology to resist interference, ensuring real-time and stable data transmission to the remote control center, providing timely and reliable data support for flood control decision-making.

[0038] In one specific embodiment, the soil texture detection module 9 uses a near-infrared spectrometer to scan the soil sample 100, acquires spectral data, uses the CARS algorithm to screen characteristic wavelengths, and quickly analyzes and outputs the content and proportion of sand, silt, and clay in the soil through the PLS regression model built into the embedded AI chip, with a clay content resolution of ±2%.

[0039] In one specific embodiment, the groundwater detector 7 adopts the capacitive principle, with a probe length of 1 meter, a resolution of 0.2 centimeters, and automatically measures the groundwater level every 30 minutes.

[0040] In one specific embodiment, the pH detection module 2 adopts the fiber optic sensing principle and is equipped with a fiber optic sensing probe. It accurately determines the soil acidity and alkalinity by detecting changes in the reflectivity of light signals. Its surface is covered with a hydrophobic nano-coating and is equipped with a periodically operating ultrasonic vibration module to effectively prevent dirt from adhering and ensure long-lasting accuracy of the detection.

[0041] In one specific embodiment, the data acquisition and analysis unit 5 further includes a flow detection radar 6 and a flow detection camera 8. The flow detection radar 6 is a side-scan radar with a working frequency of 24 GHz. It calculates the water flow velocity based on the Doppler effect and combines water level data with river cross-section data to achieve real-time flow monitoring.

[0042] In this embodiment of the invention, the energy system includes a power supply 3 (main power supply) and a solar cell (not shown in the figure), employing a dual-mode power supply design. The solar cell, serving as an auxiliary power source, can be a flexible solar thin film, fully utilizing clean energy and effectively extending the continuous field operation time. The first turntable 20 and the second turntable 22 respectively support the second rotating mechanism 19 and the third rotating mechanism 21, enabling flexible sampling actions at multiple angles and directions. The second conveyor belt 25 transports the tested soil sample 100 from the constant temperature module 24 to the recovery area, achieving continuous sampling and testing operations. All exposed equipment is made of waterproof and corrosion-resistant materials. Buffer rubber rings are used to reinforce and seal the connections between modules, ensuring long-term stable operation of the device in harsh environments such as wading and bumpy conditions. Larger internal components, such as the power supply, are located at the bottom to lower the center of gravity and further improve movement stability.

[0043] It should be understood that, in practical applications, the power supply 3 can be placed at the bottom of the device to lower the center of gravity and improve stability during movement.

[0044] In one specific embodiment, a constant temperature module 24 is also included, which has a built-in metal blower and temperature sensor to ensure that the automatic sampling unit 10 and the data acquisition and analysis unit 5 operate at a constant temperature.

[0045] Under the remote command or preset program control of the control center, the device of this utility model can autonomously complete the entire process of travel, positioning, sampling, detection, analysis and data transmission, realizing high-frequency, automatic and accurate monitoring of soil and environmental parameters of riverbanks. Combined with edge intelligence algorithms, it provides flood risk warning and ecological protection suggestions, significantly improving the intelligence level and response efficiency of flood control monitoring. It is particularly suitable for complex river environments with severe soil erosion and frequent floods, and has broad prospects for promotion and application.

[0046] The working principle and technical effects of this utility model embodiment are as follows:

[0047] After the device is started, the navigation and communication module 4 plans the path based on the GPS positioning accuracy of ±0.1 meters. The walking mechanism 1, driven by a combination of tracks and Mecanum wheels, carries the damping system formed by the shock-absorbing spring 12, rubber shock absorber 14, and foam buffer layer to cross the embankment potholes. Upon reaching the target point, it automatically enters the closed-loop process: the rotary motor 31 drives the retractable metal drill bit 32 to rotate and probe downwards. The MEMS earth pressure sensor 33 records the resistance curve in real time. Once the inflection point appears, the transverse cutter 18, under the action of the first rotating mechanism 17... The soil column is cut laterally. The sampling cutter head 30 and the sampling ring cutter 28 complete the ring cut through the combined motion of the second rotating mechanism 19, the third rotating mechanism 21, and the first turntable 20 and the second turntable 22. The soil sample 100 is completely absorbed into the sampling ring cutter 28. The telescopic mechanism 26 then lifts and quickly releases the soil sample 100 via the upper connecting buckle 27 and the lower connecting buckle 29, allowing the soil sample 100 to enter the constant temperature module 24 via the first conveyor belt 23. In this constant temperature and humidity environment, the fiber optic pH sensing unit 2 uses changes in reflectivity to determine the acidity and alkalinity. (The last sentence appears to be incomplete and possibly refers to a different process.) The nano-coating and ultrasonic vibration work together to suppress contaminants. After scanning by a near-infrared spectrometer, the CARS algorithm extracts the characteristics, and the PLS model of the embedded AI chip outputs the proportions of sand, powder, and clay particles. The resolution of clay particles is controlled within ±2%. The waste sample after detection is automatically discharged by the second conveyor belt 25, realizing continuous sampling and detection. At the same time, the side-scan radar 6, the flow camera 8, and the capacitive groundwater detector 7 continuously acquire water flow velocity, water level, and groundwater level information. All data are spatiotemporally fused with 100,000 sets of historical flood records by the embedded LSTM network, providing real-time flood risk level, future trends, and vegetation construction schemes. The results are transmitted back concurrently through LoRaWAN and 5G dual-mode redundant links. The energy is supplied by the flexible solar film and the internal power supply 3, ensuring that the device can still operate with zero maintenance in rainy weather or at night. The entire system completes the movement, positioning, sampling, detection, analysis, and early warning in an unmanned manner, solving the problems of low efficiency, data fragmentation, and poor environmental adaptability of traditional manual inspections, and significantly improving the timeliness, accuracy, and intelligence level of embankment flood control monitoring.
