[0009] Through the above technical solution, the rise and fall of the water level in the conversion box can be controlled by the operation of the water pump, and the rise and fall of the water level can be used as a trigger condition to accurately control the timing of gas sampling. For example, sampling is triggered when the water level rises to a certain level, which can ensure that gas samples under specific conditions are collected.

[0010] Preferably, a water level gauge is installed on the surface of the conversion box, and a glass window is provided on the surface of the air storage box.

[0017] Through the above technical scheme, the setting of the support frame and the reinforcing rod can increase the overall structural stability of the sampler, so that it can withstand greater weight and external forces without being easily deformed or damaged. The presence of the support frame and the reinforcing rod can also effectively reduce the vibration and vibration of the sampler during use, thereby maintaining the stability of the sampler and avoiding interference with the sampling results.

[0019] 1. The utility model can control the rise and fall of the water level in the conversion box through the operation of the water pump, and the rise and fall of the water level can be used as a trigger condition to accurately control the timing of gas sampling. For example, sampling is triggered when the water level rises to a certain level, which can ensure that gas samples under specific conditions are collected.
