Sphere off-position and falling into span insulation slot ceiling lamp shaped earthquake approach alarm

Abstract

The invention relates to a ceiling lamp type impending earthquake alarm by the movement and the fall of a sphere into a spanned insulated ditch. A triangle plate is added at the top end of a horizontal hammerhead, a conical metal disk is arranged on the plane of the triangle plate, and a hole is arranged in the center of the conical disk. When the invention stands by, the metal sphere is arrangedat the upside of the hole; when the metal sphere shakes, moves and falls in the insulated ditch, an alarm circuit is bridged and switched on so as to send out alarms and in advance evacuate people who do not sense an earthquake yet. Particularly when the earthquake occurs late at night, the alarm not only sends out the alarms to wake up people in sleep to hurriedly evacuate, but also can automatically light a ceiling lamp in case people in an impending earthquake hurry can not touch a switch. The metal sphere absolutely can not send out the alarms in stillness, namely that a building absolutely can not collapse without reasons; when the metal sphere moves and falls, and the alarm sends out the alarms, namely that the building is in shake, and an earthquake portent occurs. The invention isoptimal quakeproof equipment for treating the earthquake occurring late at night.

Description

Ball off-position rolling span insulation ditch ceiling lamp shape impending earthquake alarm 1. Technical field The present invention relates to a kind of impending earthquake alarm in the form of a ball off-position, rolling down, span insulation ditch, ceiling lamp, which is made of a metal conical plate with a hole in the center of a horizontal hammer head, and a metal ball is placed on the top of the hole. , and take the metal ball swaying out of position and rolling down into the insulating ditch to build a bridge and then energized as the alarm standard, which belongs to the impending earthquake alarm technology of the closed trigger circuit of the ball out of position and rolling down. 2. Background technology Today, although the country has many types and advanced instruments for earthquake prediction and monitoring, due to the lack of knowledge and skills on the causes of earthquakes and the selection of monitoring locations, it is difficult to make accurate predi...

Problems solved by technology

Today, although the country has many types and advanced instruments for earthquake prediction and monitoring, due to the lack of knowledge and skills on the causes of earthquakes and the selection of monitoring locations, it is difficult to make accurate predictions before the arrival of a major earthquake. The Wenchuan Earthquake is two sad examples, especially the Tangshan Earthquake, which came late at night, is even more tragic, so that people are eager to have an impending earthquake alarm with a simple structure and suitable for decoration in the bedroom. equipment
