Abstract
The utility model discloses an anti-backflow drainage grate, which mainly solves the problem that water in a pipeline flows back to a pavement to increase the drainage burden when the water level in the pipeline rises because the drainage grate in the prior art do not have an anti-backflow function. The anti-backflow drainage grate comprises a grate cover body, a fixing ring for fixing the grate cover body, a water blocking layer connected with the grate cover body through elastic equipment, arranged below the grate cover body and used for preventing water backflow, and a buoyancy device fixed below the water blocking layer. The anti-backflow drainage grate is simple in structure and convenient to implement, and has high practical value and popularization value.
Description
Technical field
The utility model relates to a kind of drainage gate, specifically, relates to a kind of interior rainwater of sewer that can automatically prevent and pours in down a chimney the reverse-filling drainage gate to the road surface.
Background technology
Drainage gate often places the sewer pipe top under each road surface as a kind of common small-sized drainage plant, is used for draining.Yet existing drainage gate all only has drain function, there is not the reverse-filling function, thereby when the heavy rain arriving, when water level goes up in the pipeline under the road surface, traditional drainage gate will pour in down a chimney the water in the pipeline to the road surface, such drainage gate not only can not well play a role in the drainage, and also can increase the weight of the draining burden.Each avenue particularly, if this situation occurs, can accelerate the appearance of waterlogging phenomenon, this has brought great inconvenience to the civic trip, the civic property has been caused very large loss, public order has been caused great harm, and after processing procedure in more can expend a large amount of human and material resources, financial resources.Therefore, a kind of can to prevent automatically that the water in the pipeline from pouring in down a chimney to the drainage gate on road surface required for people in innovation and creation.
The utility model content
The purpose of this utility model is to provide a kind of reverse-filling drainage gate, and mainly solving the drainage gate that exists in the prior art does not have the reverse-filling function, thereby the water in the pipeline can be poured in down a chimney the problem that increases the weight of the draining burden to the road surface when water level in the pipeline goes up.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The reverse-filling drainage gate, comprise the grate lid, be used for fixing the retainer plate of this grate lid, also comprise by elastic devices link to each other with the grate lid and be arranged at the grate lid under be used for the aquiclude that anti-sealing pours in down a chimney, and be fixed in the buoyant device below the aquiclude.
Further, the below of described retainer plate is provided with the side skirt that is solidified as a whole structure and is complementary with aquiclude with it.
Specifically, described side skirt is the metal skirt structure; Described grate lid is threaded with elastic devices; Described aquiclude is fixedly connected with elastic devices; Described buoyant device is the light hollow ball float; Described elastic devices drives the elastic support that aquiclude moves up and down for being used for, and described aquiclude is arranged at the lower end of this elastic support.
Consider the stability in the practical application, described retainer plate is fixed on the ground by swell fixture, and the grate lid is fixed on the retainer plate by screw.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model is provided with aquiclude and side skirt, and the two forms closed space under normal circumstances, and such set-up mode has prevented that the peculiar smell in the sewer from shedding, and has effectively solved air pollution problems inherent.
(2) the utility model is provided with the elastic support that is fixedly connected with aquiclude, and below aquiclude, be provided with the light hollow ball float, during flood season, the gravity of rainwater can separate aquiclude with the side skirt, form drainage channel, when water level in the sewer pipe goes up, the light hollow ball float will drive the aquiclude floating, form closed space with the side skirt, prevent that rainwater from pouring in down a chimney to the road surface, by such set-up mode, solved dexterously rainwater and poured in down a chimney the problem that increases the weight of the draining burden to the road surface, have substantive distinguishing features and progress, and very practical.
(3) in the utility model, elastic support is threaded with the grate lid, and such mounting means is convenient to dismounting, assembling and mobile, has fully taken into account the demand in the practical application.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the top view of Fig. 1.
In the above-mentioned accompanying drawing, the component names that Reference numeral is corresponding is as follows:
The 1-retainer plate, 2-grate lid, 3-side skirt, 4-elastic support, 5-aquiclude, 6-light hollow ball float.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, 2, the reverse-filling drainage gate, comprise grate lid 2, link to each other with grate lid 2 and be arranged at by elastic devices and be used for the aquiclude 5 that anti-sealing pours in down a chimney under the grate lid 2, be fixed in the buoyant device of aquiclude 5 belows, be used for fixing this grate lid 2 and be provided with the retainer plate 1 of the side skirt 3 that is complementary with aquiclude 5, described side skirt 3 is the metal skirt structure.
Consider the stability in the use, side skirt 3 and aquiclude 5 structure that is solidified as a whole; Aquiclude 5 is fixedly connected with elastic devices; Retainer plate 1 is fixed on the ground by swell fixture, and grate lid 2 is fixed on the retainer plate 1 by screw.
In the present embodiment, as preferably, we select elastic support 4 as elastic devices, people also can select spring, elastic rod etc. according to actual needs, as long as can drive aquiclude 5 move up and down just can, and consider the facility of dismounting, grate lid 2 is threaded with elastic support 4, as: grate lid 2 center positions are provided with the fixing hole that includes internal thread, and the upper end of elastic support 4 is provided with the screw that is provided with outer silk and top band tack screwdriver mouth that agrees with mutually with the fixing hole that includes internal thread.Consider application life, we can select the elastic support 4 of sealing.
In the present embodiment, as preferably, we select light hollow ball float 6 as buoyant device, and people also can select other ball float that buoyancy can be provided according to actual needs, as long as just can drive under the effect of buoyancy that aquiclude 5 moves upward can.
Concrete application mode of the present utility model is as follows:
Retainer plate 1 is fixed on the ground of sewer pipe top, to be fixed on the retainer plate 1 by screw with the grate lid 2 of this retainer plate 1 coupling, under the usual state, aquiclude 5 upwards supports by the elastic force of elastic support 4, form closed space with side skirt 3, prevent that the peculiar smell in the sewer from shedding.During flood season, the gravity of rainwater separates aquiclude 5 with side skirt 3, form the passage of draining, allow the smooth flow ipe of rainwater, when water level in the sewer went up, the buoyancy of light hollow ball float 6 increased, and drove aquiclude 5 floatings, form closed space with side skirt 3, prevent that the water in the sewer from pouring in down a chimney to the road surface.
According to above-described embodiment, just can realize well the utility model.
