As shown in fig. 1-2, a first aspect of the present invention discloses a sewage disposal device 1000 for a dustbin sewage disposal of a washing and sweeping vehicle. It will be appreciated that the waste fitting 1000 of the present invention is not limited to use with waste bins and may be used with other devices requiring solid-liquid separation. A drain 2001 is formed on the wall of the dustbin, and this embodiment takes the drain 2001 as an example that the drain is formed on a rear door seam 2000 of the dustbin.
The sewage draining device 1000 includes a foldable waterproof member 100 and a float 200, and specifically, the foldable waterproof member 100 and the float 200 are both built in a dustbin. The float 200 can float on the water surface by buoyancy of water.
The foldable waterproof piece 100 is fixed on the wall in a folding manner and is arranged around the sewage outlet 2001, and the top end of the foldable waterproof piece 100 is provided with a drainage notch 101, so that sewage can enter the sewage outlet 2001 from the drainage notch 101.
The float 200 is fixed at the drainage gap 101 of the foldable waterproof piece 100, and can drive the foldable waterproof piece 100 to fold or unfold under the change of the liquid level in the dustbin so as to form the drainage gaps 101 with different heights. As can be appreciated, the drainage gap 101 is a gap surrounded by the top end of the foldable waterproof piece 100, and the foldable waterproof piece 100 is driven to fold or unfold by lifting the floater 200, so that the drainage gap 101 is reduced or increased, and as shown in fig. 3 and 4, the area of the drainage gap 101 is larger than that of the drain outlet 101, so that the drainage gap 101 can block the drain outlet 101, and rapid drainage of the drain outlet 101 is realized.
When the sewage disposal device 1000 provided by the invention is used, the foldable waterproof piece 100 can be fixed on the wall of the garbage can of the washing and sweeping vehicle in a folding way, the foldable waterproof piece 100 is arranged around the sewage disposal outlet 2001, the floater 200 is fixed at the opening part arranged at the top end of the foldable waterproof piece 100, and when no water exists in the garbage can, the floater 200 drives the foldable waterproof piece 100 to be unfolded under the action of gravity, so that the water drainage notch 101 of the foldable waterproof piece 100 is lower than or flush with the bottom end of the sewage disposal outlet 2001. During operation, along with the rise of dustbin sewage liquid level, float 200 drives the top of collapsible waterproof piece 100 and rises, and the breach 101 of the drainage of collapsible waterproof piece 100 rises gradually, when discharging sewage, if silt is higher than drain 2001, when the water level descends, collapsible waterproof piece 100 descends to silt height, because silt stops, collapsible waterproof piece 100 will not descend, and the breach of top blowdown of collapsible waterproof piece 100 is higher than silt height to realize blowdown height self-adaptation, avoid silt to block up drain 2001 along with sewage is discharged from drain 2001. In conclusion, the invention realizes the sewage discharge requirement of the washing and sweeping vehicle for road surface operation with different pollution levels.
