A temperature-sensing self-starting air source device

Abstract

The invention belongs to the technical field of fire protection, and provides a temperature-sensitive self-starting air source device, which includes a composite solid propellant (11), a needle-punched cap (12), a striker (13), a spring (14) and a linkage mechanism (15 ) and fire-fighting temperature-sensitive glass bubbles (16); the composite solid propellant is encapsulated in the housing, the composite solid propellant at the bottom of the housing is connected with the needle-punched cap, and the top of the housing is provided with an opening for when the composite solid propellant decomposes Gas escapes; the striker is set at the bottom of the needle-punched fire cap at a predetermined distance from the bottom of the needle-punched fire cap, and the striker strikes the needle-punched cap through the stroke movement to ignite the composite solid propellant; the linkage mechanism connects the firing pin , Fire-fighting temperature-sensing glass bulb and spring, the linkage mechanism makes the spring form a compressive force in the direction of connection with the fire-fighting temperature-sensing glass bulb. When the fire-fighting temperature-sensing glass bulb breaks, the pressure of the spring is released, driving the linkage mechanism to move and driving the striker to move at the same time Form the impact force on the needle-punched cap.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a temperature-sensing self-starting air source device. Background technique [0002] At present, the automatic fire-fighting devices on the market all use the temperature-sensing self-starting air source device as the power source, mainly relying on the induction detection of electronic components and the pressure storage type air source to provide power. This kind of temperature-sensing self-starting air source device has been relatively mature in the field of fire protection, simple and practical, and has a large market share. However, there are several obvious shortcomings. First, both the temperature sensing element and the smoke sensing element are electronic components, and the detection sensitivity is relatively unstable, which is prone to false alarms and failures; The signal has poor reliability in complex environments and cannot play the role of det...

However, there are several obvious shortcomings. First, both the temperature sensing element and the smoke sensing element are electronic components, and the detection sensitivity is relatively unstable, which is prone to false alarms and failures; The signal has poor reliability in complex environments and cannot play the role of detection and early warning; the third is that the pressure storage type gas source is always under pressure in the standby state, and there are certain safety hazards
