Gas alarm detection device

Abstract

The invention discloses a gas alarm detection device. The device comprises a box body, and a partition plate is fixedly connected in the box body; a plurality of sound holes, air holes, a partition plate lower side detection module, a control module and an air bag are arranged at the upper end and the side edge of the box body respectively; through holes are formed in the two sides of the air bag,a buzzer and a connecting block are arranged at the upper end of the partition plate, a warning lamp is arranged at the upper end of the connecting block, and a pressing module is arranged in the connecting block and can reset the control module. The air bag can be extruded by pressing the button; the gas content in the detection cavity is eliminated; long-term accumulation of gas in the detection module is prevented; and the button moves downwards to carry out linkage work on the trigger module, so the reset reset reset circuit on the control circuit board is started, the buzzer and the warning lamp are turned off, zero clearing of the detection module is realized, and the whole structure is simple, exquisite and relatively good in stability.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a gas alarm detection device. Background technique [0002] A gas detector is an instrumentation tool for gas leakage concentration detection, including: portable gas detectors, hand-held gas detectors, fixed gas detectors, online gas detectors, etc. Gas sensors are mainly used to detect the types of gases present in the environment. Gas sensors are sensors used to detect the composition and content of gases. The measurement principle is mainly based on solid-state electrolysis method, paramagnetic method, electrochemical cell method, chemiluminescence method, etc. However, the above-mentioned technologies are all contact measurements. In industrial applications, it is easy to cause poisoning of the personnel using the detection device, and the sensing probe is susceptible to corrosion, which affects the service life of the instrument.

Problems solved by technology

However, the above-mentioned technologies are all contact measurements. In industrial applications, it is easy to cause poisoning of the personnel using the detection device, and the sensing probe is susceptible to corrosion, which affects the service life of the instrument. Frequent calibration is required during use to ensure the accuracy of the measurement.

For example, in the case of sulfur dioxide leakage in the workshop, due to the toxicity of sulfur dioxide, it needs to be detected. In the traditional technology, the sensing probe is exposed to the gas to be detected for a long time, which causes the sensing probe to be corroded and its service life is greatly reduced.
