Portable sample detection device for fire rescue site

The invention belongs to the technical field of fire rescue on-site detection, and particularly relates to a portable fire rescue on-site sample detection device. Comprising a box body and a box cover; a partition plate is arranged at an upper opening of the box body, and a liquid sample detection concave disc, a sample pretreatment concave disc, a detection controller and an electrochemical detection module are arranged on the partition plate; a battery and a vacuum pump for supplying power to each component are arranged in the box body; a gas detection tube fixing device, a sensor component box with a gas sensor and the gas sensor are arranged in the box cover; external gas passes through the sensor component box, passes through a gas detection pipe in the gas detection pipe fixing device, then enters the closed gas flow guide cavity, is discharged through a gas vent in the bottom end of the closed gas flow guide cavity, and reaches the vacuum pump through a pipeline, so that gas component detection is real
