Blow off pipe structure of protection against rodents protection against insects

Technical Field

The utility model relates to a drainage pipe field, in particular to blow off pipe structure of protection against rodents protection against insects.

Background

The national committee on health and sport requires that a rat-proof net with meshes not larger than 13mm multiplied by 13mm is arranged at the outlet of the sewer to prevent rats from invading into a room from the outlet of the sewer, which is an effective rat-proof measure, but the requirement of decades passes, and particularly, rat-proof nets are arranged at the important rat-proof units of food, diet and the like during examination and are removed after the examination, which is caused by that the rat-proof net is jammed with the sewage which is smoothly discharged, the water channel is often blocked, the sewage flows transversely and is difficult to clean.

Therefore, the Chinese patent publication No. CN201228373Y discloses a mouse preventer for a drain pipe, which is characterized in that the mouse preventer is a section of pipeline linked with the drain pipe, at least two opposite fixed baffle plates are arranged in the pipeline, the mouse preventer is horizontally connected to a water outlet of the drain pipe when in use, and the two opposite baffle plates are respectively positioned above and below, so that sewage entering the pipeline from the drain pipe can form a water seal under the shielding effect of the baffle plates, thereby effectively preventing mice from entering the drain pipe through the mouse preventer, and simultaneously preventing the mice from being blocked easily. However, the structure of the rat guard for the drain pipe is complex. In addition, the water is easily blocked by sundries, so that the water is not smoothly drained.

The sewer discharge port that chinese patent was granted publication No. CN204282525U and is disclosed does not have the block up protection against rodents board, and the effectual current protection against rodents net of having solved blocks up the smooth and easy discharge of filth easily, causes water course to block up, the sewage crossing current, and washs the problem of difficulty, and the scheme of its solution is: the structure comprises a mouse baffle plate which is rotatably arranged at the drainage outlet of the sewer, the mouse baffle plate is vertically arranged or is obliquely arranged along the drainage direction of the sewer, and the structure can prevent the mouse baffle plate from overturning to cross the mouse baffle plate to be in the vertical position along the drainage direction. This patent technique is in the low level in-service use in-process, because keep off the mouse board and be located the drainage direction outside and have filth and silt often and pile up, when the water yield is less, keep off the mouse board and receive filth and the accumulational blockking of silt to be difficult to open, also make the drainage unsmooth. The inner side surface of the mouse baffle plate in the water drainage direction is not treated by adopting a sealing structure, and if the sealing structure is arranged between the side of the mouse baffle plate and the pipeline wall, the mouse baffle plate is difficult to open smoothly during water drainage, so that the water drainage is influenced; if a gap is left between the side of the rat guard and the wall of the duct, mosquitoes can easily enter the room through the gap (generally speaking, the drain pipes of low-rise houses are all in straight rows and have no water seal).

Along with the construction of new rural areas, the construction quality of low-rise houses in rural areas is higher and higher at present, the sealing performance of doors and windows is better and better, and screen doors and screen windows are also installed in some cases, but because the drain pipes of the low-rise houses are all arranged in straight lines, water sealing is not available. Harmful organisms such as mice and cockroaches often enter the room from the drainage pipe.
