Gas alarm detection device

Abstract

The invention discloses a gas alarm detection device. The device comprises a box body, wherein a partition plate is fixedly connected in the box body, a plurality of sound holes and air holes are respectively formed in the upper end and the side edge of the box body, a detection module, a control module and an air bag are arranged on the lower side of the partition plate, two sides of the air bagare provided with through holes, the upper end of the partition plate is provided with a buzzer and a connecting block, the upper end of the connecting block is provided with a warning lamp, the connecting block is internally provide with a pressing module, the pressing module is internally provided with a trigger module, and the trigger module can reset the control module. The air bag can be extruded by pressing the button, and the gas content in the detection cavity is eliminated, thereby preventing long-term accumulation of the gas in the detection module to corrode the noble metal electrode, and prolonging the service life of the device. In addition, the downward movement of the button can carry out linkage work on the trigger module, so that the reset circuit on the control circuit board is started, the buzzer and the warning lamp are turned off, and zero clearing of the detection module is realized. 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] Gas detector is an instrumentation tool for gas leakage concentration detection, including: portable gas detector, hand-held gas detector, fixed gas detector, online gas detector, etc. Gas sensors are mainly used to detect the types of gases existing 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, 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 accurate 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.
