The working principle of the invention is as follows:

when methane is generated in the methane tank, the pressure sensor 22 reads the air pressure in the methane tank and drives the motor 10 to rotate, the motor 10 rotates to drive the other belt pulley 8 to rotate, the other belt pulley 8 rotates to drive one belt pulley 8 to rotate through the toothed belt 11, one belt pulley 8 rotates to drive the worm 7 to rotate, the worm 7 rotates to drive the worm gears 4 to rotate, the worm gears 4 rotate to drive the driving rods 5 to synchronously rotate, the driving rods 5 synchronously rotate to drive the driven rods 6 to synchronously rotate, and further the movable box body 2 is driven to vertically move, so that the volume in the tank body 1 and the movable box body 2 can be adjusted, the air pressure in the methane tank can be adjusted, the pressure can be increased when the methane quantity is insufficient so as to convey the methane to the methane tank for use, and when the internal air pressure is too high, the space can be increased, and the air pressure can be reduced so as to avoid the risk of methane leakage and even explosion, the methane tank has good use effect and strong practicability.

Under the action of the rain collecting funnel 18, rainwater can be collected and enters the arc-shaped pipe 17 from the rain collecting funnel 18, then enters the tank body 1, rainwater is accumulated between the movable box body 2 and the tank body 1 after entering the tank body 1, good sealing effect can be achieved, biogas can be effectively prevented from leaking through a gap between the tank body 1 and the movable box body 2, a rain collecting funnel 18, an arc-shaped pipe 17 and the tank body 1 form a communicating vessel, the highest position of the sealing water level in the tank body 1 is the height of the rain collecting funnel 18, thereby effectively avoiding other parts of the methane tank from being damaged due to overhigh water level, and under the action of the arc-shaped pipe 17, the arc-shaped pipe 17 can be heated by sunshine, thereby heating the sealing water body in the arc-shaped pipe 17, heating the movable box body 2 by the sealing water body to raise the temperature in the methane tank, thereby accelerating the fermentation of the waste in the marsh gas to improve the output effect and the output speed of the marsh gas.

When the movable box body 2 vertically moves, the movable box body 2 vertically moves to drive the twist screw 20 to vertically move, the twist screw 20 vertically moves to drive the rotating cylinder 19 to rotate, the rotating cylinder 19 rotates to drive the stirring impeller 21 to rotate, the stirring impeller 21 rotates to stir the biogas residues and the biogas slurry in the biogas pool, the fermentation speed can be increased, the biogas output and the biogas escape can be accelerated, the biogas residues are prevented from being accumulated to be difficult to clean, the added waste enters the adding cylinder 12 and enters the biogas residues and the biogas slurry in the tank body 1 through the adding pipe 13 under the action of gravity, the liquid level in the tank body 1 is driven to rise, the liquid level rises to drive the floating ball 26 to float upwards, the floating rotating rod 26 on the floating ball 26 drives the L-shaped rotating rod 24 to rotate through the L-shaped rotating rod 24, the sealing rotating plate 27 rotates, and the sealing rotating plate 27 rotates to seal and block the outlet of the adding pipe 13, prevent to add the interior wastes material of a section of thick bamboo 12 and continue to get into jar body 1 to can avoid the liquid level in the jar body 1 too high, when the liquid level reduced, floater 26 descends and drives sealed commentaries on classics board 27 and rotate, can make the wastes material get into jar body 1 again and ferment, thereby play automatic feed's effect.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
