A monitoring device for methane gas in a hot thaw lake pond in a tundra region is provided, comprising a top plate, an adjusting mechanism, and a monitoring mechanism. A bottom portion of the top plate is fixedly connected with a fixed column, and the fixed column is slidably mounted on the adjusting mechanism. The monitoring mechanism is connected to the adjusting mechanism, and the monitoring mechanism controls entry and exit of water to be detected and detect a methane gas in the water. The position of the mounting cylinder of the monitoring mechanism is adjusted by an electric push rod to facilitate the monitoring of methane concentration at different positions. In the mounting cylinder of the monitoring mechanism, a turntable with a filter membrane that is lifted and rotated is provided to facilitate controlling the direction of liquid movement while promoting the upward movement of the gas to detect methane concentration, and the liquid periodically to detect the methane concentration, which achieves the purpose of detecting the methane concentration by periodic liquid replacement. Additionally, the present disclosure also provides a debris removal mechanism that is capable of scraping weeds from the outside of the mounting cylinder.
