Abstract
The application discloses a sealed sewer perforated strainer, comprising a dustpan-shaped sealed plate which is mutually hinge-jointed at one side under the perforated strainer of the main body of the perforated strainer; the upper joint of the sealed plate matches fixed frame of the perforated strainer; back end of the sealed plate is fixed with a suspending arm balance weight; the moment of the balance weight is more than the deadweight of the sealed plate and less than total weight of the sealed plate with full water. Usually, the sealed plate is against the perforated strainer by the moment of the balance weight avoiding the bad smell from spreading. When raining, the rain firstly flows into the sealed plate; when the rain is almost full, the moment over the suspending arm balance weight, discharging the rain via reversing; as long as the rain continues flowing into the sealed plate, the sealed plate keeps reversing; when the rain stops, the sealed plate comes back to the original state. Thereby, the application solves the sealing problem of the sewer and clarifies the air environment.
Description
Technical field
The application relates to water drain grate.
Background technology
Sewers (or following ditch) below the road surface such as present street in some cities and towns, road are not totally enclosed, separated by a distance all do not have an irony double-edged fine-toothed comb, its effect one is to be convenient to wash away when rainwater flows into sewer dirt, the 2nd, prevent that the big foreign material in ground from pouring in the sewer, because the grid or the eyelet of double-edged fine-toothed comb are open-air, so the foul smell of sewer can be emerged in double-edged fine-toothed comb, foul smell is smoked the people, influences air quality.
Summary of the invention
The application proposes a kind of sealed type water drain grate for solving the problem that present water drain grate emits foul smell.
The application's technical scheme is, it comprises existing double-edged fine-toothed comb body, the tool feature is, the seal disc of the hinged dustpan shape of a side below double-edged fine-toothed comb, the flat mouth of going up of seal disc matches with the solid frame of double-edged fine-toothed comb, a cantilever counterweight is fixed in the rear end of seal disc, and the moment of counterweight is filled with gross weight behind the water greater than the deadweight of seal disc less than seal disc.
The application's advantage is: often, seal disc withstands on by the moment of counterweight and plays a part to prevent to escape on the foul smell below the double-edged fine-toothed comb.When rainy, rainwater at first flows into to collect in the seal disc and deposits, and when fast collection is filled with, has surpassed the moment of cantilever counterweight, overturns and releases the rainwater that collection is deposited, as long as rainwater continues to flow into seal disc and can continue to keep rollover states; In the rainwater stopping time, seal disc recovers reset condition.Therefore, the application has solved the sealing problem of sewer, has purified air ambient.
Description of drawings
Fig. 1 is the application's a schematic diagram.
Among the figure: 1---double-edged fine-toothed comb; 2---seal disc; 3---hinge; 4---the cantilever counterweight; 5---sewer.
The specific embodiment
As shown in Figure 1, the application's sealed type water drain grate comprises the double-edged fine-toothed comb 1 that matches with sewer 5, side below double-edged fine-toothed comb 1 is hinged with the seal disc 2 of dustpan shape by hinge 3, the flat mouth of going up of seal disc 2 matches with the solid frame of double-edged fine-toothed comb 1, a cantilever counterweight 4 is fixed in the rear end of seal disc 2, and the moment of cantilever counterweight 4 is filled with gross weight behind the water greater than the deadweight of seal disc 2 less than seal disc 2.
