A water immersion alarm device based on reversible hydrogel

Abstract

The invention discloses water immersion alarm equipment based on reversible hydrogel. The equipment comprises a casing, an inner cavity of the casing is divided into an induction chamber, an electrical chamber and a buzzing chamber by partition plates, the outer side of the casing is provided with a water guide pipe communicated with the induction chamber, an induction body made of a reversible hydrogel material is mounted in the induction chamber, a power supply unit, a wireless signal transmitter, a warning light and a pressure sensitive element are mounted in the electrical chamber, and a buzzer is mounted in the buzzing chamber; the components are connected through an internal circuit, and a sensing part of the pressure sensitive element extends into the sensing body in the sensing chamber through the corresponding partition plate. The structural design of the equipment is reasonable. When water leakage of the water guide pipe occurs, the internal pressure is increased after the induction body is solidified with water, the situation can be sensitively sensed by the pressure sensitive element in the water immersion alarm equipment, and an alarm function is quickly enabled; moreover, the hydrogel material has high water absorption characteristics, diffused leakage of the water is avoided, a certain buffering and protection effect is achieved, and more disposal time is provided.

Description

technical field [0001] The invention relates to the technical field of water immersion alarm, in particular to a water immersion alarm device based on reversible hydrogel. Background technique [0002] Intelligent buildings need to use a large number of intelligent equipment and corresponding water supply and drainage, air-conditioning systems, and establish a complete building automation system, which can not only reduce energy consumption, save manpower and material resources, but also create a good living environment for users. However, the use of a large amount of water and air-conditioning also brings hidden dangers: there are many related pipelines in the computer room, warehouse, transmission or sewage pipeline, and the environment is complex. Flooding can easily cause a short circuit, which can lead to serious safety accidents. For this reason, various flood alarms have occurred. [0003] The traditional water immersion alarm is mainly to install a sensor at the de...

AI Technical Summary

Problems solved by technology

These components determine that the production cost of the water immersion alarm is high, and the structure is complex. If many water immersion sensors (generally more than 10) are required to be used in conjunction, the operation is extremely cumbersome and error-prone.

In addition, the traditional traditional water immersion alarm only has an alarm function, does not have the ability to buffer the water situation, and cannot buy time for processing
