Description

Technical Field

[0001] This utility model relates to the technical field of hazardous gas detection devices, specifically a hazardous gas detection device for fire protection facilities based on an electrochemical sensor. Background Technology

[0002] Electrochemical sensors operate by reacting with the analyte gas and generating an electrical signal proportional to the gas concentration. A typical electrochemical sensor consists of a sensing electrode (or working electrode) and a counter electrode, separated by a thin electrolytic layer. The gas first reacts with the sensor through tiny capillary openings, then through a hydrophobic barrier layer, and finally reaches the electrode surface. This method allows a sufficient amount of gas to react with the sensing electrode to form a adequate electrical signal while preventing electrolyte leakage from the sensor. Gas diffusing through the barrier reacts with the sensing electrode, which can employ either an oxidation or reduction mechanism. These reactions are catalyzed by electrode materials designed for the analyte gas. A current proportional to the analyte gas concentration flows between the positive and negative electrodes via a resistor connected between the electrodes. Measuring this current determines the gas concentration. Because this process generates current, electrochemical sensors are often called current-gas sensors or miniature fuel cells. Electrochemical sensors are commonly used in hazardous gas detection devices in fire protection systems.

[0003] Chinese patent discloses a hazardous gas detection device (authorization announcement number CN 217820297 U). This patented technology includes a hazardous gas detector with an air inlet; it also includes a catapult and an air inlet pipe. The catapult includes a catapult power supply structure and a catapult component. The rear of the air inlet pipe is connected to the air inlet of the detector, and the front of the air inlet pipe is fixedly connected to the catapult component. The catapult power supply structure has a force that causes the catapult component to move in a certain direction, and the catapult component drives the air inlet pipe to move. When it is necessary to detect the gas inside a tunnel, the air inlet pipe is simply launched into the tunnel using the catapult. The detector then draws the gas sample from inside the tunnel to a hazardous gas detector outside the tunnel for testing. This process eliminates the need for personnel to carry the hazardous gas detector into the area being tested, thus determining whether the hazardous gas levels exceed the standard, greatly protecting testing personnel and reducing the safety risks during the testing process.
