Abstract

The utility model relates to a municipal sewage manhole cover with a filter net. Two side walls of a manhole are respectively provided with a groove vertical to the manhole, and the lower ends of the two grooves are extended in the same direction to form arc grooves parallel to the manhole; the two sides of the filter net are respectively provided with a lug; and the two lugs are respectively inserted in the two vertical grooves and are rotatably and fixedly arranged in the two arc grooves. According to the municipal sewage manhole cover disclosed by the utility model, the filter net is additionally arranged below the existing sewage manhole cover and does not influence any use function of the existing sewage manhole cover; and even if the manhole cover opens and a passenger carelessly falls into the manhole, the passenger is not in life danger.

Description

The municipal sewage well lid that a kind of band is slipped through the net

Technical field

The utility model relates to a kind of municipal sewage well lid, relates more specifically to a kind of well lid that can prevent the pedestrian to fall sink hole.

Background technology

The drainage system in city needs to arrange an inspection shaft at a certain distance, and the well head of inspection shaft is being covered with a well lid at ordinary times, opens well lid when needs check drainage pipe and dredge, complete after topped upper well lid again.But owing to mismanagement or the natural calamity reason (washing well lid open such as heavy rain) of well lid, so that passerby falls into the down-hole accidentally even the tragedy of getting killed happens occasionally, very sorry.

The utility model content

The municipal sewage well lid that provides a kind of band to slip through the net is provided the purpose of this utility model, to improve the defective that exists in the known technology.

For achieving the above object, the municipal sewage well lid that the band that the utility model provides is slipped through the net, its structure is, respectively offers one perpendicular to the groove of inspection shaft on the two side of inspection shaft, the lower end of two grooves extends to level in the arc groove of inspection shaft equidirectionally; One slips through the net, and its both sides respectively are provided with a projection; Described two projections are inserted in respectively in two vertical grooves, and are fixed on rotatably in two arc grooves.

The municipal sewage well lid that described band is slipped through the net wherein is 180 degree between the groove on the two side.

The municipal sewage well lid that described band is slipped through the net, slipping through the net wherein is made of metal frame and wire lath.

The utility model has increased one deck below existing cesspool cover slips through the net, and does not affect any use function, falls into because of carelessness even well lid is opened passerby, also entail dangers to life not.

Description of drawings

Fig. 1 is that the utility model is established reeded inspection shaft schematic diagram.

Fig. 2 is the schematic diagram of slipping through the net that the utility model is provided with projection.

Fig. 3 is that of the present utility model slipping through the net is fixed on structural representation in the inspection shaft.

The specific embodiment

See also Fig. 1, the technical solution of the utility model is that respectively offer 1, two groove 1 of a groove in the two side of known inspection shaft 100 be equal angles (180 degree) each other, two grooves 1 in accompanying drawing for vertically offering.Article two, the lower end of groove 1 transfer to extend equidirectionally 11, two arc grooves 11 of two arc grooves in accompanying drawing for being horizontally disposed with, forming between groove 1 and the groove 11 is 90 degree.

Of the present utility model slipping through the net 2 is to be framework 21 by hard material (such as metal frame), at framework 21 wire laths 22 is installed, and respectively establish between 23, two projections 23 of a projection framework 21 both sides also is equal angles (180 degree).The size of projection 23 is as the criterion moving in groove 1.

During concrete the installation, 2 two projections 23 of slipping through the net are inserted in respectively in two grooves 1 until bottom of groove 1, then rotation slips through the net 2, makes two projections 23 snap in respectively fixing (as shown in Figure 2) in the groove 11.When heavy rain occurs, even the well lid of inspection shaft is washed away, can not be flushed away because two projections 23 are stuck in to fix in the groove 11 yet, thereby realize that the utility model can guarantee the purpose of pedestrains safety.
