A household earthquake early warning and alarm device

Abstract

The invention discloses a home earthquake early warning and alarming device. The home earthquake early warning and alarming device comprises a base and a plurality of vertical columns, wherein the vertical columns are vertically distributed on the base in an even way; an airproof outer cover covers the exterior of each vertical column; a control terminal with a power source and an audio alarming mechanism are arranged on the base, and the audio alarming mechanism is connected with the power source; a triggering mechanism comprises a first permanent magnet and a second permanent magnet, the first permanent magnet is arranged on the base, and the second permanent magnet and the first permanent magnet have the same polarity, and are arranged in the same direction; the first permanent magnet repels the second permanent magnet, and then the second permanent magnet is suspended in the airproof outer cover. Compared with the prior art, the home earthquake early warning and alarming device has the advantages that the second permanent magnet is ascended, descended and jittered in the direction of a guide rail due to the fluctuation of a magnetic field before a strong earthquake, and a metal electric pickup sheet on a balance conductive rod is connected with a conductive joint, so that the power source is used for supplying power for the audio alarming device, and the warning sound is sent out to prompt the user, thereby reaching the early warning purpose; the user can control the optimum escape opportunity, and the survival rate is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of earthquake prediction, in particular to a household earthquake early warning and alarm device. 【Background technique】 [0002] Once an earthquake occurs at night or near the morning, many people are still sleeping soundly in the room, which makes people hard to guard against. If an earthquake occurs in this time period, it will be the most harmful to people's lives. When a magnitude 7.0 earthquake occurred in Lushan County, Sichuan Province, my country at 8:02 on April 20, 2013, some people were still asleep. If the earthquake can be achieved in the early stage of the earthquake, if more than ten seconds can be won, many people will be able to avoid disability or death. Earthquake is an irresistible natural disaster with a wide range of damage, great harm to life and property. So far, scientific knowledge has not grasped the law of earthquake occurrence, and it is far from reaching the level of weather...
