Description

Technical Field

[0001] The present invention relates to the technical field related to flash flood disaster early warning monitoring, and in particular to a flash flood disaster early warning monitoring device and a monitoring system. Background Art

[0002] Flash floods refer to floods, debris flows and landslides caused by rainfall in hilly areas. Flash floods are sudden, with concentrated water volume, high flow velocity and strong scouring and destructive power, often causing local disasters. Therefore, it is very necessary to prevent flash floods and improve the level of flood disaster warning by installing flash flood disaster warning devices. In real life, the monitoring of flash flood disasters is mostly independent of each other, but a single technical monitoring method cannot meet the actual needs of disaster monitoring and early warning, which makes the prediction function of the flash flood disaster monitoring and early warning system weak and the acquisition of relevant information insufficient; In order to overcome the above defects, the prior art 1 (Chinese patent with application number 201922458588.6 and application date 2019-12-31) is an integrated dynamic disaster warning system, including a bearing device, a data acquisition component and an early warning unit, the bearing device includes three sets of legs for inserting into the soil, a support frame with a plurality of mounting seats and a rain shield for shielding rain, the data acquisition component includes a rain gauge for collecting rainwater, a flow rate monitor for monitoring water flow rate, a flow sensor for monitoring water flow rate, a solar power supply component for power supply, a positioning module for positioning, a wireless transmission module for communication, a liquid level sensor for monitoring the liquid level of the rain gauge and a microprocessor, the early warning unit includes a central processor for data processing, an input device for data input, a video conference module for video conference, and an information release unit for information release; There is also prior art 2 (Chinese patent with application number 202221474749.6 and application date 2022-06-14), a flash flood disaster warning device, comprising a support rod, a telemetry terminal, a solar panel, a rain gauge and a water level gauge are arranged on the support rod, a top rod is connected to the upper end of the support rod, the top rod is in a cross-shaped structure, the solar panel is mounted on the top rod, the telemetry terminal is sealed and mounted on the upper end of the top rod, a lightning rod is mounted on one end of the horizontal part of the top rod, and a rain gauge and a water level gauge are mounted on the other end; the telemetry terminal comprises a waterproof housing, a battery module, a main control panel electrically connected to the battery module, and a button electrically connected to the main control panel, a Beidou antenna panel, a GPS Beidou timing card, and a SIM card are arranged in the waterproof housing, and also comprises a number of aviation plugs electrically connected to the main control panel, the Beidou system and the network communication system form a dual channel to back up each other, and when a base station fails, data can be switched to the Beidou system for transmission without long-distance wiring; And prior art three (Chinese patent with application number 202120894149.4 and application date 2021-04-28) A remote monitoring and early warning device for flash flood disasters, comprising a main body component, a monitoring and early warning component and a control component. The inner bottom wall of the main body component is installed with a monitoring and early warning component, and the inner side wall of the main body component is installed with a control component. The water level and water flow at the warning location can be monitored by a water flow velocity meter and an ultrasonic water level meter. At the same time, a rain gauge can monitor the rainfall. The specific conditions of mudslides and flash floods at the warning location can be monitored by the cooperation of a vibration sensor and a camera. The water flow velocity meter, ultrasonic water level meter, rain gauge, vibration sensor and camera transmit the monitoring signal to the server, which performs simulation and inference through the server and transmits the early warning information to the external device for viewing by the staff.

[0003] Although the existing technology can increase the acquisition of relevant information, during the working process, the installed rain gauge is easily polluted by the external environment, which makes it unable to accurately record the precipitation, causing the deviation of the measurement value, thereby delaying the early warning and increasing the risk of disasters. The accumulation of dirt in the rain gauge can easily affect the service life of its materials and components, which will not only affect its working efficiency, but also increase the maintenance burden of the system. Moreover, the rain gauge can only monitor the current rainfall situation and cannot provide accurate forecast data, which may cause the disaster prevention measures to lag and affect the disaster prevention effect.

[0004] In view of the above problems, it is urgently necessary to carry out innovative design based on the original flash flood disaster early warning monitoring device and monitoring system. Therefore, we proposed a flash flood disaster early warning monitoring device and monitoring system that can well solve the above problems. Summary of the invention

Example

[0020] In this embodiment, in order to improve the effective utilization rate of water resources, the driving component is used to reduce the problem of impurities in the water causing adverse effects on subsequent use.

Since a second filter plate 19 is provided on the top of the water tank 8, the rainwater stored in the water tank 8 is convenient to filter, which reduces the adverse effects of impurities in the water on subsequent use and improves the effective utilization rate of water resources. The meteorological monitor 20 on the monitoring frame 1 is convenient for monitoring the meteorological conditions in the monitoring area. The meteorological monitor 20 can capture the meteorological elements in the monitoring area in all directions, providing a rigorous data basis for information processing. The water level monitor 21 is convenient for monitoring the rise and fall of the water level. The monitored data is processed by the processor 22. The meteorological monitor 20 is provided.

The first motor 10 is set to make the overall drive simple and fast, which not only reduces the problem of increased cost caused by the need to set more driving structures, but also reduces the overall easy damage caused by the numerous driving structures. The problem is solved, and the overall service life is improved. The buffer rod 34 moves inside the storage frame 35, so that the meteorological monitor 20 on the storage plate 33 is shaken, which is convenient for the meteorological monitor 20 to be cleaned, and ensures that the meteorological monitor 20 is always in good working condition, thereby providing strong support for accurate meteorological monitoring and greatly improving the quality and reliability of meteorological data. The buffer cylinder 36 arranged at the bottom of the storage plate 33 is buffered by the buffer column 37, so that the support of the meteorological monitor 20 on the storage plate 33 is more stable, and the damage problem caused by the interference of external environmental factors to the meteorological monitor 20 is reduced, and the continuity and accuracy of the meteorological monitoring data are ensured. When the meteorological monitor 20 does not need to be cleaned, the storage plate 33 can be adsorbed on the monitoring frame 1 through the adsorption effect of the first magnetic block 38 and the second magnetic block 39, so that the meteorological monitor 20 at the upper end can be effectively monitored, and the problem of errors in meteorological monitoring data caused by the shaking of the storage plate 33 is reduced.
