Abstract
The utility model discloses an automatic open close device of manhole mouth, which is used for sealing sewage, smell and mosquitoes of the manhole and realizing the automatic draining. The automatic open close device of manhole mouth comprises a water storage and a floating ball. The upper opening of the water storage with inversed-cone shape and the manhole cover are in sealed connection, the lower opening of the water storage is in the shape of through hole, the floating ball is arranged in the water storage with inversed-cone shape, and the diameter of the floating ball is larger than the diameter of the through hole at the lower opening of the water storage. The utility model which can finish the functions of draining and sealing isolation by lifting the floating ball, has the advantages of simple structure, is low in production cost, easy in installation and maintenance, suitable for the municipal construction to improve the city appearance.
Description
Technical field
The utility model relates to the automatic open and close device that a kind of inspection shaft mouth uses, and is used to seal inspection shaft sewage smell mosquito and realizes automatic drainage simultaneously.
Technical background
Existing inspection shaft is finished sluicing by the through hole that inspection shaft covers, and need not sluice, and the peculiar smell in the inspection shaft also can cover through hole by inspection shaft scurries out, and particularly spring and summer season, foul smell, mosquito in the sewer are gone out in the lump, influence the urban environment looks.
Summary of the invention
The utility model provides a kind of inspection shaft mouth automatic open and close device, during excess surface water, ponding flows into inspection shaft, opening/closing device is opened automatically, ponding enters, in the time of need not sluicing, opening/closing device is closed, and blocks the inspection shaft mouth, stops foul smell, mosquito to be come in and gone out, the utility model is achieved in that inspection shaft mouth automatic open and close device, comprise water storing vessel, ball float, it is characterized in that the suitable for reading and inspection shaft lid of back taper water storing vessel is tightly connected, end opening is the through hole shape, the back taper water storing vessel is built-in with a ball float, and the diameter of described ball float is greater than water storing vessel end opening through-hole diameter.Local area water flows in the back taper water storing vessel by the inspection shaft lid, and ball float rises, and the automatic open and close device is opened, and ponding flows into inspection shaft by the end opening through hole of water storing vessel, finishes the sluicing function; In the time need not sluicing, ball float falls within back taper water storing vessel bottom, and owing to the bottom through-hole diameter of its diameter greater than water storing vessel, the opening that is communicated with inspection shaft is plugged, sewer and atmospheric isolation.
The utility model finishes sluicing and the isolated function of sealing by the lifting of ball float, and simple in structure, cost of production is low, and is convenient for installation and maintenance, can be widely used in urban construction, improves appearance of city.
