Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As Fig. 1, Fig. 2, the folding collecting methane device of drift, it comprises biogas probe 1, cover 2 suspends, suspension cover stent 3, pneumatic tube 4, floatation device 7 is formed, suspension cover stent 3 swims in the fermentation vat 6, the cover 2 that suspends is installed on the suspension cover stent 3 and forms air chamber, array floatation device 7 is installed in the bottom of suspension cover stent 3, floatation device 7 immerses in the fermented liquid of fermentation vat 6, biogas probe 1 be positioned at the cover 2 that suspends the top and and the suspension cover 2 during expansion contact, pneumatic tube 4 passes suspend cover 2 and air chamber connection, biogas probe 1 is connected the load end connection pneumatic tube 4 of compressor by pilot circuit with compressor.

Described floatation device 7 is made up of counterweight 9 and float 10, and there is the cover of suspension film 8 on the surface of floatation device 7, the floatation device 7 and the cover 2 that suspends are an integral body, counterweight 9 and float 10 play balance suspension cover 2, the distance of regulating counterweight 9 and float 10 adapts to the influence of different fermentations batching come-up dregs to air chamber, float 10 can with how many free liftings of fermented liquid of fermentation vat 6, and the dress fermented product what do not influence, even the many again destruction fermentation vats that also do not influence of aerogenesis.If aerogenesis is too much, biogas can be raised float 10 to exposing the fermentation liquid level, and last point is a bit missed, but can not damage any device.
