Abstract

The invention discloses a sewer manhole cover with overflow prevention and filtering functions, which includes a manhole cover body, filter assembly and anti-spill assembly, A guard plate is arrangedon the outside of the well cover body, one side of the guard plate is hinged with the well cover body through a hinge shaft, a stepped hole is arranged on the upper part of the well cover body, a leakage plate is arranged in the stepped hole, a plurality of leakage holes are arranged on the leakage plate, a transverse reinforcing plate and a vertical reinforcing plate are fixedly arranged on the lower part of the well cover body, and the filter assembly is arranged on the bottom of the transverse reinforcing plate and the vertical reinforcing plate; The filter assembly comprises a fixed ring and a filter screen, wherein the filter screen is arranged in the fixed ring; the lower part of the filter screen is intermittently provided with an anti-overflow assembly; the anti-overflow assembly comprises a water collecting plate and a launching cylinder; the upper part of the launching cylinder is provided with an anti-falling plate; one side of the launching cylinder is provided with a rotating shaft; the other side is correspondingly provided with a water stopper; one side of the rotating shaft is connected with a counterweight block; and the other side is connected with an anti-overflow sealing cover. The invention can filter and intercept garbage, prevent dirt clogging, prevent sewage from overflowing, and has good use effect.

Description

technical field [0001] The invention relates to the field of urban public facilities appliances, in particular to a sewer manhole cover with overflow prevention and filtering functions. Background technique [0002] The sewer is a kind of urban public facility, which refers to the pipeline for removing sewage and rainwater from buildings; it also refers to the underground channel for discharging sewage and rainwater in cities, factories or villages. The entrance of the sewer is generally deep, and a certain amount of water needs to be reserved for the convenience of dredging and maintenance openings, which are covered with sewer manhole covers. [0003] The sewer manhole cover is used to cover the road or the deep well at home to prevent people or objects from falling. On the one hand, the sewer manhole cover wears a lot under long-term use, and it will be broken when it encounters an accidental impact. Because there is no protective interception device in the sewer, it will...

Problems solved by technology

[0003] The sewer manhole cover is used to cover the road or the deep well at home to prevent people or objects from falling. On the one hand, the sewer manhole cover wears a lot under long-term use, and it will be broken when it encounters an accidental impact. Because there is no protective interception device in the sewer, it will be broken. The debris falls straight to the bottom of the sewer, which brings the risk of clogging and makes cleaning inconvenient. On the other hand, there are situations in life where shops and businesses dump kitchen waste into the sewer, or pedestrians’ cigarette butts are swept into the sewer by sanitation workers. Phenomenon, long-term garbage accumulation reduces the capacity of the sewer and will cause the problem of sewer blockage, affecting the flow of normal sewage, such as a sewer manhole cover with multi-layer filtration disclosed in Chinese Patent No. CN201520286781.5. The filter layer filters and purifies the sewage entering the sewer, but it cannot clean up the filtered impurities. When garbage and other debris accumulate on the filter layer, there is a risk of clogging the filter layer, which is extremely inconvenient to clean, and because some sewer pipes If the road is blocked, sewage backflow may occur in other low-level sewers, and underground sewage overflows the sewers, resulting in the phenomenon of cross-flow of sewage, which not only has a negative impact on environmental sanitation, but also is difficult to solve later
