A gas alarm detection device

Abstract

The invention discloses a gas alarm detection device, which comprises a box body, a partition board is fixedly connected in the box body, a plurality of sound holes and ventilation holes are respectively arranged on the upper end and the side of the box body, and a detection module, a control module and an air bag are arranged on the lower side of the partition board. , there are through holes on both sides of the airbag, a buzzer and a connecting block are arranged on the upper end of the partition, a warning light is arranged on the upper end of the connecting block, a pressing module is arranged in the connecting block, and a trigger module is arranged in the pressing module. The control module is reset and cleared. Pressing the button can not only squeeze the air bag, eliminate the gas content in the detection chamber, prevent the gas from accumulating in the detection module for a long time, corrode the precious metal electrodes, and increase the service life of the device, but also the button can be moved down to activate the trigger module. The linkage work realizes the activation of the reset and reset circuit on the control circuit board, turns off the buzzer and warning light, and realizes the reset of the detection module. The whole structure is simple and exquisite, and the stability is good.

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 a kind of instrumentation tool for gas leakage concentration detection, including: portable gas detector, hand-held gas detector, fixed gas detector, online gas detector, etc. The gas sensor is mainly used to detect the type of gas existing in the environment. The gas sensor is a sensor used to detect the composition and content of the gas. The measurement principle is mainly based on solid-state electrolysis method, paramagnetic method, electrochemical cell method, chemiluminescence method, etc. However, the above techniques are all contact measurements. In industrial applications, people who use the detection device are prone to poisoning, and the sensor probe is susceptible to corrosion, which affects the service life of the instrument. Frequent calibration is required during use to ensure the a...

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.
