Abstract

The invention relates to the technical field of fire prevention, and discloses a point-type fire early warning device utilizing the principle of bimetallic sheets, comprising a mounting plate, a cross bar is movably connected inside the mounting plate, and a left side of the cross bar is movably connected with a Connect the plate, drive the fixing block to the inside through the cross bar, then align the groove on the upper surface of the upper end cover with the groove on the lower surface of the mounting plate, and then release the cross bar, under the action of the return spring, the cross bar is pushed to the outside. , make the middle fixing block enter the stepped groove of the upper end cover, fix the upper end cover, bend the bimetal sheet, and cooperate with the movable plate, the annular plate and the V-shaped rod to push the trigger shaft to move upward, causing the voltage to change and trigger the The electric signal makes the alarm sound, and at the same time, the external fire extinguishing device connected by the wire is activated to start the fire extinguishing. The device has a simple structure, few electronic components, and receives less external interference. It can still be used in a strong magnetic and electric environment, with stability and safety Sex is higher.

Description

technical field [0001] The invention relates to the technical field of fire prevention, in particular to a point-type fire early warning device utilizing the principle of bimetallic strips. Background technique [0002] Cities have the characteristics of dense buildings, concentrated population, concentrated property, and many sources of inflammable and explosive materials, many points, and wide areas, which brings more fire and explosion hazards. Once fire and explosion occur, casualties will be high. Economic losses are serious, so we must be aware of safety protection and install fire alarm devices in places prone to fire. [0003] Most of the existing fire early warning devices have complex structures, which are very troublesome to install, maintain and inspect, and have complex internal structures and many electronic components, which are greatly affected by strong electric and strong magnetic environments, and may cause the problem of untimely alarms. [0004] In orde...
