With continued reference to fig. 2 and 3, in order to improve the sealing performance when the first cover plate 331 and the second cover plate 332 are covered, the free end of the first cover plate 331 is provided with an abutting boss 3311, usually, the abutting boss 3311 is integrally connected with the first cover plate 331, the abutting boss 3311 extends toward the other end along one end of the side edge of the free end of the first cover plate 331, the free end face of the second cover plate 332 is recessed from the outside to the inside to be provided with an abutting groove 3321, the shape of the abutting groove 3321 is adapted to the shape of the abutting boss 3311, when the first cover plate 331 and the second cover plate 332 are covered on the first connecting pipe 312, the abutting boss 3311 is spliced into the abutting groove 3321, at this time, the first cover plate 331 and the second cover plate 332 are positioned with each other, the matching accuracy between the first cover plate 331 and the second cover plate 332 is improved, and the abutting boss 3311 and the abutting groove 3321 can increase the abutting area of the free end of the first cover plate 331 and the free end of the second cover plate 332, thereby prolonging the path of the odor flowing from the gap between the first cover plate 331 and the second cover plate 332 into the first connecting pipe 312, improving the sealing performance between the free end of the first cover plate 331 and the free end of the second cover plate 332, and further improving the effect of blocking the odor.

In addition, the sealing gasket 5 is fixedly connected to the end face of the end of the first connecting pipe 312 extending into the sealing cavity 4, generally, the sealing gasket 5 is arranged in a circular ring shape, so as to be matched with the circular contour of the first connecting pipe 312, the sealing gasket 5 can be fixed to the first connecting pipe 312 in an adhesive manner, when the first cover plate 331 and the second cover plate 332 cover the first connecting pipe 312, the sealing gasket 5 is respectively abutted against the first cover plate 331 and the second cover plate 332, the sealing gasket 5 can improve the sealing performance when the first cover plate 331 and the second cover plate 332 cover the first connecting pipe 312, and further improve the odor isolating effect of the blocking device 3.

The implementation principle of the drainage system of the green energy-saving house in the embodiment of the application is as follows: through installing separation device 3 on a plurality of branch pipes 2, separation device 3 can carry out the separation to the foul smell under the condition that can supply waste water to pass through, and then has reduced the foul smell of flowing backward to the building indoor.

When the wastewater passes through the blocking device 3, the wastewater flows from the upper section to the lower section of the branch pipe 2, the wastewater pushes the first cover plate 331 and the second cover plate 332, so that the first cover plate 331 and the second cover plate 332 rotate downwards relative to the first connecting pipe 312 to open the first through hole 3121, and the wastewater can flow to the second connecting pipe to discharge the wastewater; after the wastewater is discharged, the spring 336 rebounds and resets, the spring 336 pulls the connecting block 335 to move upwards, the connecting block 335 pulls the first cover plate 331 and the second cover plate 332 to cover the first connecting pipe 312 through the first connecting rod group 333 and the second connecting rod group 334, when the spring 336 is in a natural state, the first cover plate 331 and the second cover plate 332 cover and abut against one end, extending into the sealed cavity 4, of the first connecting pipe 312, so that the first through hole 3121 is closed, and the odor is blocked by the first cover plate 331 and the second cover plate 332 at this time.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
