Description

Technical Field

[0001] This utility model relates to the field of flash flood disaster monitoring and early warning technology, and in particular to an intelligent flash flood disaster monitoring and early warning device. Background Technology

[0002] In my country, the complex topography and widespread distribution of mountainous and hilly areas make flash floods a frequent and severe natural disaster. These regions, with their undulating terrain, numerous rivers with variable flow directions, are highly susceptible to rapid flooding during heavy rains, potentially triggering secondary geological disasters such as landslides and mudslides. Statistics show that mountainous and hilly areas account for over 80% of my country's total land area, containing more than 4,600 counties (cities) vulnerable to flash floods. Flash floods not only threaten a wide area but are also characterized by their suddenness and destructive power, often causing severe casualties and property damage, making them one of the deadliest types of natural disasters in my country.

[0003] To effectively address the threat of flash floods, timely and accurate monitoring and early warning are crucial. However, traditional monitoring methods often suffer from data transmission delays and low early warning accuracy, making it difficult to meet the needs for rapid response and precise early warning of flash floods. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the existing technology and provide an intelligent monitoring and early warning device for flash flood disasters, which can accurately monitor rainfall and water level changes in the target area, provide timely early warnings, and improve the accuracy and reliability of the early warnings.

[0005] This utility model is achieved through the following technical solution: a smart monitoring and early warning device for flash floods, comprising a support column, a control box equipped with a telemetry terminal, a water level monitoring device for monitoring water level data, a rainfall monitoring device for monitoring rainfall data, and an alarm device; the control box, water level monitoring device, rainfall monitoring device, and alarm device are all installed on the support column, and the water level monitoring device, rainfall monitoring device, and alarm device are all electrically connected to the telemetry terminal; the telemetry terminal receives the water level data and the rainfall data, and sends an alarm signal to the alarm device;

[0006] The control box is equipped with a storage battery, which is electrically connected to the water level monitoring device, the rainfall monitoring device, the alarm device, and the telemetry terminal respectively.

[0007] The water level monitoring device includes a multi-stage water level monitoring device and a water level gauge. The multi-stage water level monitoring device includes a water level contact acquisition unit and several water level contact sensors electrically connected to the water level contact acquisition unit. The water level contact acquisition unit is located inside the control box and electrically connected to the telemetry terminal. Several water level contact sensors are sequentially arranged at the bottom of the support column along the extension direction of the support column. The water level gauge is electrically connected to the telemetry terminal, and the reference plane of the water level gauge is on the same horizontal plane as the water level contact sensor with the lowest installation height.

[0008] Compared with existing technologies, the intelligent monitoring and early warning device for flash floods provided by this utility model collects water level and rainfall data in real time by installing water level monitoring devices and rainfall monitoring devices on supporting columns and transmitting the data to a telemetry terminal. When the rainfall and water level reach thresholds, the telemetry terminal sends an alarm signal to the alarm device, providing timely early warning. Through multi-level water level monitoring devices, multi-level early warning is achieved. This multi-level early warning mechanism helps to detect water level anomalies in advance, giving relevant personnel more response time to take timely measures to avoid or mitigate potential disasters. Combining the water level data collected by the water level gauge with the water level levels monitored by the multi-level water level monitoring devices helps to improve the accuracy and reliability of the early warning. Furthermore, the telemetry terminal can transmit water level and rainfall data to a monitoring center platform for analysis by relevant personnel, further ensuring the accuracy and reliability of the early warning.

[0009] Furthermore, the supporting column is a hollow column with an opening on one side of its bottom, through which its inner cavity communicates with the outside. Both the water level gauge and the water level contact sensor are installed within the inner cavity of the supporting column, positioned above the opening. Concealing the water level gauge and water level contact sensor within the supporting column protects them, reduces external environmental interference, and improves detection accuracy.

[0010] Furthermore, the water level gauge is a bubble-type water level gauge, which includes a water level detection unit, an air guide pipe, and an air chamber. The water level detection unit is installed inside the control box and electrically connected to the telemetry terminal. The air chamber is installed in the inner cavity of the support column and is flush with the water level contact sensor with the lowest installation height. One end of the air guide pipe is connected to the water level detection unit, and the other end is connected to the air chamber. The bubble-type water level gauge has high measurement accuracy, which helps to improve the accuracy and reliability of water level data detection.

[0011] Furthermore, the multi-level water level monitoring device includes four water level contact sensors for different levels of early warning, and the four water level contact sensors are arranged sequentially at equal intervals. By setting four water level contact sensors at different heights, different levels of early warning for water levels can be achieved.

[0012] Furthermore, the system also includes an image acquisition device for collecting on-site information. This device is mounted on the supporting column and electrically connected to the telemetry terminal and the battery. The image acquisition device captures images of the on-site environment, allowing relevant personnel to analyze the rising floodwaters and the surrounding flood situation.

[0013] Furthermore, the alarm device includes a warning light, which is positioned near the top of the supporting column and electrically connected to the telemetry terminal. The alarm device also includes a voice broadcaster for announcing relevant warning information, positioned near the top of the supporting column and electrically connected to the telemetry terminal. By flashing the warning light and broadcasting relevant warning information through the voice broadcaster, the device ensures that surrounding people are promptly and effectively alerted when a warning is issued.

[0014] Furthermore, it also includes a remote loudspeaker device, which is installed inside the control box and electrically connected to the telemetry terminal, the battery, and the power amplifier in the voice broadcaster. The remote loudspeaker device enables remote, manual announcements to be made in advance of impending flood disasters.

[0015] Furthermore, it also includes a solar panel, which is positioned near the top of the supporting column and is electrically connected to the battery to supply power to it. The solar panel generates electricity to provide power for the intelligent monitoring and early warning equipment for flash floods, effectively solving the power supply problem.

[0016] Furthermore, it also includes a vertical ruler, which is mounted on the support column. One end of the vertical ruler near the bottom of the support column is flush with the lowest-height water level contact sensor. The vertical ruler has a fluorescent effect. This fluorescent design allows for clear observation of the on-site water level both day and night.

[0017] Furthermore, it also includes a base and a lightning rod, which are respectively installed at the bottom and top of the supporting column. By installing the lightning rod, the equipment is protected from lightning strikes, ensuring that the equipment can operate normally during thunderstorms and guaranteeing the accuracy and continuity of early warnings.

The telemetry terminal 30 receives the water level data and the rainfall data and sends an alarm signal to the alarm device 80.

[0026] The following is a detailed description of the specific structure of the intelligent monitoring and early warning device for flash floods.

[0027] The supporting column 10 is a hollow column with an opening 11 on one side of its bottom, through which the inner cavity of the supporting column 10 communicates with the outside. In this embodiment, the cross-sectional shape of the supporting column 10 is circular. Of course, in other alternative embodiments, the cross-sectional shape of the supporting column 10 may be elliptical, rectangular, or other polygonal shapes.

[0028] In this embodiment, the intelligent monitoring and early warning device for flash floods further includes a mounting bracket (not shown in the figure). The mounting bracket is positioned near the top of the support column 10, and the control box 20 is mounted on the mounting bracket. The mounting bracket can be detachably mounted on the support column 10 using screws, clips, or other methods, or it can be fixed to the support column 10 by welding. Similarly, the control box 20 can also be detachably mounted on the mounting bracket using screws, clips, or other methods.

[0029] The control box 20 has a rectangular shape. A telemetry terminal 30 is installed inside the control box 20. The telemetry terminal 30 includes a 4G communication module (not shown) and a control module (not shown). The control module is electrically connected to the 4G communication module. The control module receives water level data collected by the water level monitoring device and rainfall data collected by the rainfall monitoring device. Based on the received water level and rainfall data, the control module sends an alarm signal to the alarm device. The control module communicates with a remote central platform via the 4G communication module, transmitting the received water level and rainfall data to the remote central platform for analysis by relevant personnel.

[0030] In this embodiment, the control box 20 has an IP66 protection rating. The design of the control box ensures that the telemetry terminal is not damaged by external factors such as rain and insects. Furthermore, the bottom of the control box 20 has a cable hole (not shown) for cable passage. Preferably, an elastic seal is provided inside the cable hole, and the elastic seal has a slit for the cable to pass through. This improves the sealing performance of the control box and further protects the electronic components such as the telemetry terminal inside the control box. The elastic seal can be made of open-cell polyethylene foam (i.e., opseloyl foam), rubber, or other elastic seal materials.

[0031] The water level monitoring device includes a multi-stage water level monitoring device 40 and a water level gauge 50. The multi-stage water level monitoring device 40 includes a water level contact acquisition unit 41 and four water level contact sensors 42. The water level contact acquisition unit 41 is electrically connected to the water level contact sensors 42 and is housed within the control box 20, and electrically connected to the telemetry terminal 30. The four water level contact sensors 42 are located within the inner cavity of the support column 10 and are arranged at equal intervals along the extension direction of the support column 10. Specifically, the support column 10 has four mounting through holes located above the opening of the support column 10. The water level contact sensors 42 are correspondingly installed in the mounting through holes, with their sensing probes exposed through the mounting through holes. It should be noted that the number of water level contact sensors 42 is not limited to four; it can be two, three, or more, depending on actual needs. The water level contact sensor 42 is a water level sensor, which is existing technology and will not be described in detail here. By setting multiple water level contact sensors 42, a multi-level early warning mechanism can be realized. The telemetry terminal 30 can send alarm signals of corresponding levels to the alarm device according to different early warning levels, which helps to detect water level anomalies in advance, giving relevant personnel more response time so that timely measures can be taken to avoid or mitigate possible disasters.

One end of the air guide pipe 52 is connected to the water level detection host 51, and the other end is connected to the air chamber 53. It should be noted that the bubble-type water level gauge is existing technology. Of course, in other alternative embodiments, the water level gauge is not limited to a bubble-type water level gauge and can be other water level gauges, such as ultrasonic water level gauges, radar water level gauges, etc. Using other water level gauges ensures that the reference plane of the water level gauge is on the same horizontal plane as the water level contact sensor with the lowest installation height; in other words, the water level reference point of the water level gauge is on the same horizontal plane as the water level contact sensor with the lowest installation height.

[0033] The rainfall monitoring device 60 is mounted on the support column 10, and is positioned near the top of the support column 10 and electrically connected to the telemetry terminal 30.

[0036] In this embodiment, the alarm device 80 further includes a voice broadcaster 82, which is positioned near the top of the supporting column 10 and electrically connected to the telemetry terminal 30. The voice broadcaster 82 receives alarm signals of different levels transmitted by the telemetry terminal and broadcasts corresponding warning information.

Of course, in other alternative embodiments, the use is not limited to the voice broadcaster 82; a buzzer or other sound alarm can be used to provide audible warnings.

[0037] In this embodiment, the intelligent monitoring and early warning device for flash floods further includes a remote broadcasting device 90. The remote broadcasting device 90 is housed within the control box 20 and is electrically connected to the power amplifier in the telemetry terminal 30 and the voice broadcaster 82.

[0040] In this embodiment, the intelligent monitoring and early warning device for flash floods also includes a vertical ruler 110. The vertical ruler 110 is mounted on the supporting column 10, with one end of the vertical ruler 110 near the bottom of the supporting column 10 flush with the lowest-height water level contact sensor 42. The vertical ruler 110 facilitates on-site personnel's observation of the water level. Preferably, the vertical ruler 110 has a fluorescent effect; specifically, the vertical ruler 110 can be made of a fluorescent material, or a fluorescent layer can be provided on the scale surface of the vertical ruler 110, with the scale directly etched on the fluorescent layer. The fluorescent vertical ruler design allows for clear observation of the on-site water level during both day and night.

When an alarm is triggered, the telemetry terminal sends an alarm signal to each in-home alarm response terminal, which immediately issues an alarm to notify indoor personnel to evacuate.

[0044] Compared with existing technologies, the intelligent monitoring and early warning device for flash floods provided in this embodiment collects water level data, rainfall data, and on-site image data in real time by installing water level monitoring devices, rainfall monitoring devices, and image acquisition devices on supporting columns. This data is then transmitted to a telemetry terminal. When rainfall and water level reach thresholds, the telemetry terminal sends an alarm signal to the alarm device, providing timely early warning. Through multi-level water level monitoring devices, multi-level early warning is achieved. This multi-level early warning mechanism helps to detect water level anomalies in advance, giving relevant personnel more response time to take timely measures to avoid or mitigate potential disasters. Combining the water level data collected by the water level gauge with the water level levels monitored by the multi-level water level monitoring devices helps to improve the accuracy and reliability of the early warning. Furthermore, the telemetry terminal can transmit water level data, rainfall data, and on-site image data to the monitoring center platform for analysis by relevant personnel, further ensuring the accuracy and reliability of the early warning.
