Further, the structure of the sealing block is a frustum shape, and the small-diameter end of the sealing block faces the water seal pipe. The diameter of the small-diameter end of the sealing block is smaller than the inner diameter of the water seal pipe, the diameter of the large-diameter end of the sealing block is larger than the inner diameter of the water seal pipe, when the sealing block seals the water seal pipe, one part of the sealing block is located in the water seal pipe, the other part of the sealing block is located in the drainer, and the sealing performance between the sealing block and the water seal pipe is improved.

Further, the elastic piece is connected with the inner wall of the drainer through a fixing piece.

Furthermore, the drainer is internally provided with a U-shaped connecting plate below the water seal pipe, and two ends of the elastic part are respectively connected with the U-shaped connecting plate and the sealing block.

Further, the edge of the sealing block is in contact with the U-shaped connecting plate and is in sliding connection with the U-shaped connecting plate. Prevent that the sealed piece from leading to the sealed piece can't the accurate sealed water sealed pipe because the undulant slope of water.

Further, the number of the buoys is not less than 2. The plurality of buoys provide sufficient buoyancy to drive the elastic member and the floating block.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses the device makes the drainer not receive the influence of impurity in the water through being equipped with flotation pontoon, elastic component and sealed piece, simultaneously sealed piece is the frustum type, makes the leakproofness of drainer good, prevents that coal gas from leaking.
