A simple flash flood early warning device based on the principle of super seepage runoff

Abstract

The invention discloses a simple mountain torrent early-warning device based on an excess infiltration runoff principle. The simple mountain torrent early-warning device comprises a water collecting cup and an information display unit installed in the water colleting cup. A water penetrating port is formed in the bottom wall of the water collecting cup. An adjusting turn button used for adjusting a leakage speed is installed at the water penetrating port. The information display unit comprises a yellow precaution device, an orange precaution device and a red precaution device which are successively from a low water level to a high water level. The simple mountain torrent early-warning device has the advantages that the structure is simple, the excess infiltration runoff principle is used as the basis, and the excess infiltration runoff process is modeled and visualized; by means of the adjusting and setting the adjusting turn button, mountain torrents are accurately simulated; the device is high in adjustment, applicable to most mountainous areas, and high in popularization; in addition, when the device is in use, the forming and eruption of the mountain torrents can be grasped in real time only by noticing the prompts of the precaution devices and buzzer alarms, and the monitoring and early warning effects of the mountain torrents are further improved, so that the life and property safety of people in mountainous areas is ensured.

Description

technical field [0001] The invention relates to a simple and convenient mountain torrent early warning device based on the principle of super seepage runoff, belonging to the technical field of natural disaster early warning. Background technique [0002] Mountain torrents are floods that occur in mountain streams and ditches. Because the slopes of the ground and riverbeds in mountainous areas are relatively steep, and the runoff and confluence are faster after rainfall, they will form sharply rising and falling flood peaks. Therefore, mountain torrents are sudden and the water volume Concentration, strong destructive power and other characteristics. At the same time, the precipitation in the same period in mountainous areas is generally greater than the sum of plant interception, land filling, evaporation during the rainy period, and infiltration in the same period, so it is easy to form super-seepage runoff, which is characterized by rapid changes in time history and spati...

Problems solved by technology

The technology of the equipment is simple, but the system often has unstable operation, such as the exposed water level monitoring equipment and facilities, and the wind, sun, and water are prone to aging, resulting in equipment failure.

In addition, the operation, maintenance and management of this type of equipment is very difficult. The mountain torrent disaster monitoring equipment is placed outside the open air, especially if the monitoring equipment is deployed in the wild and unmanned, it is very easy for the equipment to be stolen or destroyed by man.
