Abstract

The utility model relates to a grate for preventing sewage and rain, and belongs to a sewer device. The grate for preventing sewage and rain is characterized in that the lower portion of the grate for preventing sewage and rain is provided with a plurality of tilting plates which can seal each bar-shaped hole. The grate for preventing sewage and rain can prevent foul gas in a sewer overflowing and mosquitoes and flies coming out. Meanwhile, the grate for preventing sewage and rain can prevent small filth on the ground dropping into a well channel. Rain water or sewage overcomes the elasticity of the springs of the bottoms of the tilting plates by the gravity to cause the tilting plates to turn downward; therefore, the rain water or the sewage leaks into a sewer, which is favorable for keeping air freshness and environment sanitation. Meanwhile, the work amount that a well channel is cleaned is reduced.

Description

Gratings preventing sewage and rain

The utility model relates to a kind of antifouling anti-harmful inlet for stom water combs, and belongs to sanitation.

Inlet for stom water is combed and is generally ironcasting, is used to cover at rainwater well head or sewage well head.Present inlet for stom water has a plurality of unlimited bar holes on combing, and ground rainwater or sewage are from bar hole bleeds sewer.Such inlet for stom water is combed two problems, filthy gas in the first sewer and the mosquitos and flies that grows in sewer can come out by the bar hole that opens wide, atmosphere pollution, the harm sanitation of environment, it two is that ground assorted little dirt can drop in the hoistway by the bar hole that opens wide, and easily hoistway is stopped up.

The purpose of this utility model is to provide a kind of antifouling anti-harmful inlet for stom water of subsidiary a plurality of turnover panels to comb, turnover panel can be sealed each bar hole, prevent that the excessive and mosquitos and flies of filthy gas in the sewer from coming out, and stop that ground assorted little dirt falls in the hoistway, and ground rainwater or sewage can bleed in the sewer owing to turnover panel upset downwards.

Concrete structure of the present utility model and mode of occupation are illustrated by following drawings and Examples.

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is a upward view of the present utility model;

Fig. 3 is a cross-sectional drawing of the present utility model, and wherein dotted line is depicted as the turnover panel position of upset downwards;

Fig. 4 is the sectional drawing of turnover panel.

An embodiment of the present utility model is, below each bar hole (2) of antifouling anti-harmful inlet for stom water comb (1), the turnover panel (3) that can seal bar hole (2) and can overturn is housed downwards, turnover panel (3) is enclosed within on the axle (7) of TBE (threaded both ends), axle (7) passes from antifouling inlet for stom water is combed circular hole on each bar rib (6) of (1) bottom, axle (7) two ends tighten with nut (8), the spring (5) that makes turnover panel (3) seal bar hole (2) is centered around on the axle (7), in the bottom surface of turnover panel (3) two ribs (4) are arranged, one end of rib (4) is useful on the circular hole of wearing axle (7), and turnover panel (3) also can be made by the steel sheet through antirust processing by plastic plate.

Such inlet for stom water is combed and is covered on well head, turnover panel (3) is sealed bar hole (2) by the elastic force of spring (5), this can prevent that the dunghill in the sewer from falling in the hoistway, and ground rainwater or sewage flow to antifouling inlet for stom water and comb (1) when going up, the gravity of rainwater or sewage overcomes the elastic force of spring (5), make turnover panel (3) upset downwards, the sewer that just bleeds has suffered.

It is identical that appearance and size of the present utility model is made the appearance and size of combing with original inlet for stom water, the size that can not change so original well head just can replace with the utility model one type, although it is simple in structure, but with environmental sanitation effect is arranged very to keeping with fresh air, also alleviated the workload that dredges a well clearly simultaneously.

Claims

1, antifouling anti-harmful inlet for stom water grate, a plurality of bar holes are arranged above it, it is characterized in that: the turnover panel (3) that can seal bar hole (2) and can overturn downwards is housed below each bar hole (2), turnover panel (3) is enclosed within on the axle (7) of TBE (threaded both ends), pass axle (7) circular hole from each bar rib (6) of antifouling anti-harmful inlet for stom water grate (1) bottom, tighten with nut (8) at the two ends of axle (7), and the spring (5) that makes turnover panel (3) seal bar hole (2) turns around on axle (7).

2, antifouling anti-harmful inlet for stom water according to claim 1 is combed, and it is characterized in that: there is bar rib (4) bottom surface of turnover panel (3), and an end of rib (4) is useful on the circular hole of wearing axle (7).

3, antifouling anti-harmful inlet for stom water according to claim 1 and 2 is combed (1), it is characterized in that: turnover panel (3) is to make by rigid plastic sheet or through the steel sheet of antirust processing.
