A drainage device includes a closed chamber, a liquid pumping mechanism, and a liquid discharge mechanism. The drainage device can also include a controller. The closed chamber may be filled with liquid and gas for discharge. The liquid pumping mechanism pumps the liquid in the closed chamber, and prevents the liquid in the liquid pumping mechanism from flowing back to the closed chamber. The liquid discharge mechanism discharges the liquid in the liquid pumping mechanism to the outside, and prevents outside air from flowing into the closed chamber.

1. A drainage device, comprising: a closed chamber filled with an amount of liquid and gas, the closed chamber defining a fluid channel and a gas channel in a top end, and a slag discharge hole in the bottom end thereof;a liquid pumping mechanism pumping the liquid in the closed chamber, and preventing the liquid in the liquid pumping mechanism from flowing back to the closed chamber, the liquid pumping mechanism comprising a drive assembly, a telescopic assembly, and a first sealing assembly, the telescopic assembly defining a telescopic chamber, the driving assembly comprising a connecting pole; anda liquid discharge mechanism discharging the liquid in the liquid pumping mechanism to outside, and preventing outside air from entering into the closed chamber, the liquid discharge mechanism comprising a second sealing assembly, the second sealing assembly comprising an action piston fixed to an end of the connecting pole and a flexible member sleeved on the connecting pole and attached to the action piston;wherein the first sealing assembly and the second sealing assembly are received in the telescopic assembly and a major portion of the telescopic assembly is positioned within the closed chamber, the drive assembly drives the action piston to move, thereby pumping the liquid in the closed chamber into the telescopic chamber through the first sealing assembly, and discharging to the outside through the second sealing assembly. 2. The drainage device of claim 1, wherein the telescopic assembly further defines a plurality of liquid discharge holes in a sidewall thereof. 3. The drainage device of claim 1, wherein the action piston defines a plurality of permeable holes. 4. The drainage device of claim 1, wherein the connecting pole extends out of the telescopic assembly, the drive assembly further comprises a follower fixed to an end of the connecting pole extending out of the telescopic assembly, a turntable, and a drive rod positioned on the turntable, and the drive rod is connected to the follower. 5. The drainage device of claim 4, wherein the follower defines a restricting groove, and the drive rod has a drive end slidably received in the restricting groove. 6. The drainage device of claim 1, wherein the first sealing assembly comprises a fixed piston fixed in the telescopic chamber, and a flexible member attached to the fixed piston. 7. The drainage device of claim 6, wherein the first sealing assembly further comprises a filter fixed in the telescopic chamber and opposite to the fixed piston. 8. The drainage device of claim 7, wherein the flexible member of the first sealing assembly or the second sealing assembly is a circular silicone mat, and the filter is a metal mesh filter. 9. The drainage device of claim 1, wherein the action piston comprises a sealing surface slideably engaged with a sidewall of the telescopic assembly, thereby separating the telescopic chamber into a first chamber and a second chamber. 10. The drainage device of claim 1, wherein the drive assembly comprises a receiving body, a drive piston movably received in the receiving body, and a drive rod; the receiving body is positioned on the outer surface of the closed chamber, and the drive rod connects the drive piston to the connecting pole. 11. The drainage device of claim 1, further comprising a controller, wherein the controller has a sensor for detecting liquid level in the closed chamber, and controls the movement of the drive assembly. 12. The drainage device of claim 1, wherein the closed chamber further comprises a sealing cover for sealing the slag discharge hole.
