[0043] Specifically, when in use, the battery 16 is used to power the control mainboard 17, and under the action of the control mainboard 17, the motor 1501, the GPS locator 18, the information transmission module 19, the mud level meter 3 and the video monitor 4 can be powered respectively. After the support column 1 is installed, the control mainboard 17 controls the motor 1501 to work. At this time, the worm 1502 and the worm wheel 1503 can drive the rotating shaft 1504 to rotate, and then drive the cantilever 2 to rotate. As the cantilever 2 rotates upward, the cantilever 2 can be opened. After the cantilever 2 is opened, the mud level meter 3 and the video monitor 4 will The support column 1 is extended to facilitate monitoring and early warning of debris flow disasters caused by valley-type landslides; when a debris flow disaster is detected, the control main board 17 controls the motor 1501 to reverse, so that the cantilever 2 can be stored in the second cavity 102 of the support column 1. As the cantilever 2 is stored in the second cavity 102, the mud level meter 3 and the video monitor 4 are also driven into the second cavity 102, so that the mud level meter 3 and the video monitor 4 can be protected, so that when a debris flow disaster occurs, the debris flow can effectively prevent the mud level meter 3 and the video monitor 4 from being damaged.

[0044] The application of mud level meter 3 in debris flow monitoring is mainly reflected in the following aspects:

[0045] Real-time monitoring of mud level changes: Mud Level Meter 3 can monitor the mud level changes of debris flow in real time. By measuring the height and change rate of the mud level, it can promptly warn of the potential risk of debris flow.

[0046] Calculate flow velocity and flow rate: Combined with the real-time parameters measured by the mud level meter 3, the real-time flow velocity, real-time flow rate, the total amount of a debris flow process and the solid outflow of a debris flow can be calculated, so as to more accurately evaluate the scale and intensity of the debris flow.

[0047] Improve the reliability of the early warning model: Through refined terrain measurement and mud level monitoring, the existing debris flow early warning model has been optimized, the reliability of the early warning model has been improved, and a new solution has been provided for solving the problem of debris flow monitoring and early warning.

[0048] Integration with other monitoring technologies: The Mud Level Meter 3 is used in combination with other monitoring equipment such as panoramic cameras and rain gauges to achieve intelligent empowerment and effectively improve the effectiveness of disaster prevention and mitigation.

[0049] Working principle of ultrasonic mud level meter 3: Ultrasonic mud level meter 3 uses the change of sound propagation speed in different media to determine the interface position. When the sound wave encounters the boundary of different media, it will be reflected or refracted. The reflected or refracted signal is received and analyzed to determine the interface position. This technology is widely used in wastewater treatment, mining wastewater treatment and other fields to ensure the normal operation and treatment efficiency of the equipment.

[0050] The application of video surveillance device 4 in debris flow mainly includes functions such as real-time monitoring, early warning and remote monitoring.

[0051] Key features of debris flow identification camera:

[0052] High-definition and wide-angle shooting capabilities: The camera should have high-definition and wide-angle shooting capabilities, and be able to monitor the formation and movement of debris flows in an all-round and continuous manner.

[0053] Image processing capability: The camera needs to have powerful image processing capabilities to automatically identify the characteristics of debris flows, such as the movement speed of the debris flow front and the particle size of the debris, so as to quickly issue an early warning.

[0054] Remote monitoring and data transmission functions: The camera should have remote monitoring and data transmission functions, and be able to transmit the monitored information to relevant departments in a timely manner to provide decision-making support.

[0055] Ability to resist harsh environments: The camera needs to be able to resist wind, rain, and high temperatures to ensure normal operation under extreme weather conditions.

[0056] Design principles and technical applications of debris flow identification cameras:

[0057] The debris flow recognition camera combines advanced camera technology, image processing technology and artificial intelligence algorithms. Through training with a large number of real scene samples, the system can accurately identify disasters such as landslides, rockfalls, and debris flows. Once abnormal conditions such as mountain deformation, collapse, and falling blocks are detected, the system will immediately issue a warning message and record all monitoring data and warning events to provide data support for disaster analysis and subsequent prevention work.

[0058] The application of GPS locator 18 in debris flow is mainly reflected in the following aspects:

[0059] Topographic survey and geological profile survey: GPS combined with total station is used in the topographic survey and geological profile survey of debris flow gullies, which is efficient, fast and accurate. Through control measurement, field data collection and drawing of geological profiles and topographic maps, the topographic and geological conditions of debris flow gullies can be understood more accurately.

[0060] Precipitation warning: In debris flow warning and forecasting, GPS technology can predict precipitation by inverting atmospheric precipitable water volume (PWV). By comparing and analyzing PWV and actual precipitation data, the PWV critical line can be determined, thus providing a basis for precipitation warning in debris flow basins. This method not only improves the accuracy and timeliness of precipitation, but also proves the importance of GPS inverted PWV in debris flow warning.

[0061] Deformation monitoring: GPS technology is also widely used in deformation monitoring, such as urban ground subsidence, dam deformation, bridge deformation, landslide monitoring, etc. Through continuous, real-time, high-precision monitoring, the occurrence of geological disasters such as debris flows can be discovered and warned in a timely manner.

[0062] Working principle of GPS Locator 18:

[0063] Satellite system: The core of GPS positioning lies in its huge satellite network, which consists of multiple satellites distributed in different orbits of the earth, ensuring that any corner of the world can receive signals from at least four satellites. These satellites continuously send radio signals containing timestamps and satellite location information to the surface of the earth.

[0064] Signal reception: GPS receivers have a special chip built into them to capture these satellite signals. When the receiver receives signals from at least four satellites at the same time, it can begin to calculate its own position. Small deviations in time can lead to inaccurate positioning, so the signal from the fourth satellite is used to calibrate the time error.

[0065] Calculating location: After receiving satellite signals, the GPS receiver uses the principle of triangulation to calculate its own location. It measures the propagation time of the signal from each satellite to the receiver, and uses the known speed of light to convert the time difference into distance, and then uses complex mathematical algorithms to solve the three-dimensional coordinates of the receiver.

[0066] Error correction: In order to improve positioning accuracy, the GPS system also uses a variety of error correction technologies, such as differential GPS (DGPS) and real-time kinematic differential GPS (RTK GPS), which can further reduce errors and make positioning results more reliable.

[0067] In summary, the GPS locator 18 plays an important role in debris flow monitoring and early warning. It improves the accuracy and timeliness of geological disaster early warning through terrain measurement, precipitation early warning and deformation monitoring.

[0068] A protection component 6 is provided at the upper end of the support column 1, and the protection component 6 is used to protect the photovoltaic power generation panel 10; a transmission component 5 is provided at the front end of the support column 1, and the transmission component 5 is used to transmit power to the protection component 6; the protection component 6 includes a slide rail 601, a slide hole 602, a slider 603, a protective plate 604 and a slide rod 605, and the slide rails 601 are fixedly connected to the front and rear sides of the upper end of the support column 1, and the slider 603 is slidably connected inside the slide rail 601, and the protective plate 604 is fixedly connected between the sliders 603; a slide hole 602 is opened on the front end surface of the slide rail 601 at the front end, and a slide rod 605 is slidably connected inside the slide hole 602, and the slide rod 605 is fixedly connected to the slider 603; the transmission component 5 includes a moving rod 501, a moving seat 502 and a transmission rod 503, the circumferential surface of the slide rod 605 is rotatably connected to the transmission rod 503, the end of the transmission rod 503 away from the slide rod 605 is rotatably connected to the moving seat 502, and the lower end of the moving seat 502 is fixedly connected to the moving rod 501.

[0069] Specifically, when the cantilever 2 is opened, as the cantilever 2 rotates upward, after the cantilever 2 contacts the moving rod 501, the cantilever 2 will squeeze the moving rod 501 to move upward, and then with the cooperation of the moving seat 502 and the transmission rod 503, the sliding rod 605 can be driven to slide inside the sliding hole 602, and then the slider 603 can be driven to slide inside the sliding rail 601. As the two sliders 603 move in opposite directions, the protective plate 604 will be driven to open, so that the protective plate 604 no longer blocks the photovoltaic panel 10, which is beneficial for the photovoltaic panel 10 to charge the battery 16, which is beneficial for the long-term and stable operation of the device and also reduces energy waste. When the cantilever 2 rotates downward, the cantilever 2 no longer squeezes the moving rod 501, and then the moving rod 501 and the moving seat 502 move downward under the action of gravity, and then with the cooperation of the transmission rod 503, the sliding rod 605 can be driven to slide inside the sliding hole 602. As the sliding rod 605 moves, the slider 603 is driven to slide inside the sliding rail 601, so that the two protective plates 604 are closed. After the protective plates 604 are closed, the photovoltaic panel 10 can be protected, thereby effectively preventing the stones of the mudslide disaster from hitting the photovoltaic panel 10, realizing the inclusion of the photovoltaic panel 10 and improving the service life of the photovoltaic panel 10.

[0070] A square hole 9 is provided on the front end surface of the support column 1 , and the square hole 9 is connected to the second cavity 102 . When working, the cantilever 2 can be easily stored by setting the square hole 9 .

The wireless early warning transmitter 20 is provided with a signal transmitting end and a receiving end, wherein the transmitting end and the wireless early warning transmitter 20 are an integrated structure, and the receiving end is installed at the resident's place or on the roadside. When working, when the monitored data exceeds the preset threshold, the control main board 17 controls the transmitting end of the wireless early warning transmitter 20 to transmit a signal outward, and then the receiving end receives the signal of the wireless early warning transmitter 20 to issue an alarm, thereby improving the accuracy and timeliness of monitoring.

[0072] The front end of the support column 1 is fixedly connected to a fixing plate 12, and two fixing plates 12 are provided.

When working, after the cantilever 2 is stored in the support column 1, the stretched spring 14 facilitates the moving seat 502 to slide on the guide rod 13, thereby facilitating the moving seat 502 to move downward. At the same time, under the action of the stretched spring 14, it is also convenient for the protective plate 604 to be in a closed state at all times, so that the photovoltaic panel 10 can be stably protected.

[0073] The lower ends of the support column 1 are fixedly connected with mounting plates 7 on both sides, and the upper end surface of the mounting plate 7 is provided with mounting holes 8. When working, the support column 1 can be conveniently fixed at a desired location by setting the mounting plate 7 and cooperating with the mounting holes 8.

[0074] A seismic sensor 21 and a soil moisture monitoring module 22 are fixedly connected inside the third cavity 103 . Both the seismic sensor 21 and the soil moisture monitoring module 22 are electrically connected to the control mainboard 17 .

[0075] Application of seismic sensor 21 in debris flow:

[0076] Monitoring ground vibrations: Seismic sensors 21 can detect vibrations from the movement of the earth’s crust and seismic waves. In areas prone to landslides, these sensors can capture ground vibrations caused by landslide activity.

[0078] Auxiliary research: The data collected by the seismic sensor 21 can also be used to analyze and evaluate the dynamic parameters of debris flow, providing an important basis for the study and prediction of debris flow.

[0079] Seismic sensors 21 play an important role in debris flow monitoring. They can not only monitor surface vibrations in real time and issue early warnings of debris flow disasters, but also provide valuable data for the study and prediction of debris flows.

[0080] The application of soil moisture monitoring module 22 in debris flow is mainly reflected in the debris flow early warning system. Monitoring the critical soil moisture content for the initiation of debris flow:

Through stepwise regression analysis, an empirical relationship between critical soil moisture content and soil permeability, porosity and particle curvature coefficient can be established. This method is more reliable and accurate than the traditional prediction model that uses critical lines and burst lines to identify debris flow.

[0082] The monitoring methods of soil moisture content mainly include sampling method and in-situ measurement method:

[0083] Sampling method: Determine the moisture content of soil samples after sampling in the field. This method is accurate but time-consuming.

[0084] In-situ measurement method: Use instruments and equipment to directly measure soil moisture content in the field, such as TDR (time domain reflectometry) and FDR (frequency domain reflectometry) use the principle of electromagnetic waves to measure the dielectric constant of the soil. These methods are non-destructive and can be monitored in real time, but the measurement accuracy is low.
