Background

Urban rain and sewage pipelines are connected in a mixed mode and in a staggered mode, so that sewage is directly discharged, and the surface water body is black and smelly. The black and odorous water body not only damages urban living environment, but also seriously affects urban image. In 2015, the 'action plan for preventing and treating water pollution' issued by State academy clearly proposes the target: before the end of 2020, black and odorous water in built-up areas of cities above ground level is controlled within 10%. In the year 4 of 2019, the ministry of housing and urban and rural construction, the ministry of ecological environment and the development and improvement committee printed the action scheme for improving quality and increasing efficiency of urban sewage for three years (2019-2021), which indicates that after the three-year effort, the urban construction areas above the ground level basically have no direct discharge port of domestic sewage, and basically eliminate black and odorous water. The point source pollution caused by direct discharge, substandard discharge and illegal discharge of domestic sewage and industrial wastewater without treatment is one of the main sources of black and odorous water pollutants. The control of pollution sources is well done, and the method is the most fundamental means for treating the black and odorous water body pollution. Wherein, plugging illegal and unknown discharge openings into the river is one of effective measures.

The plugging of the underwater unidentified discharge port has the following difficulties: on one hand, an upstream inspection well cannot be found, and upstream plugging cannot be performed; on the other hand, the discharge pipe is large in diameter and high in water head pressure, so that the rubber air bag is difficult to plug. In the water-rich areas in south, water-carrying masonry is generally adopted to play a role in blocking and closing water, which puts high requirements on the professional performance of operators, and simultaneously, the personal safety of the operators is endangered by water carrying operation.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an unknown row's mouth plugging device under water, includes river levee, row's mouth and shutoff part, the shutoff part includes pit shaft, 90 elbows and reducing pipe, and the pit shaft is connected to 90 elbows one end, and the reducing pipe is connected to the other end, and pit shaft, 90 elbows and reducing pipe are inside to communicate with each other, and the one end that 90 elbows were kept away from to the pit shaft is connected with detachable and connects long pit shaft for the height of extension pit shaft.

Preferably, a circle of sealing rubber ring is wrapped around the reducing pipe, and the cross section of the sealing rubber ring is trapezoidal.

Preferably, the upper end of the shaft and the lower end of the lengthening shaft are both provided with flanges, connecting holes are circumferentially distributed on the flanges, bolts are arranged in the connecting holes, and the lower ends of the bolts are connected with nuts.

Preferably, a rubber flange gasket is arranged between the two flanges.

Preferably, the lengthening shaft and the inner wall of the shaft are both provided with plastic steel steps.

Preferably, the materials of the shaft, the 90-degree elbow and the reducing pipe are all stainless steel

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses according to the depth of water more than row's mouth, confirm row's mouth plugging device required height, if this depth of water is greater than the height of pit shaft in the shutoff part, then utilize the flange, the installation prolongs the pit shaft, then insert row's mouth with the shutoff part in, make shutoff part and row's mouth zonulae occludens through reducing pipe and the sealed rubber ring of parcel around reducing pipe, accomplish interim shutoff, reduced the risk nature of shutoff under water, can effectively ensure operation personnel's personal safety, in addition, the utility model discloses can realize having better high efficiency and economic nature to different pipe diameters, the shutoff of arranging the mouth under the different depth of water.
