Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 6, an embodiment of the present invention provides a specific implementation manner of a device at a rain gate opening, including a grate 1, a filter screen 2 and a base 3, where the base 3 is a hollow structure, the grate 1 and the filter screen 2 are respectively disposed in the hollow structure, the filter screen 2 is located below the grate 1, the grate 1 is hinged to one side of the base 3, and the filter screen 2 is hinged to the other side of the base 3.
Specifically, the grate 1 is hinged to one side of the base 3, and specifically, the grate is fixed and hinged through a first bolt hole 7 of the grate and a base bolt hole 15 on the base 3 by a bolt 5 which sequentially pass through a spring gasket 6 and a nut 4; the filter screen 2 is hinged to the other side of the base 3, and specifically, the bolt 5 sequentially penetrates through the second bolt hole 11 of the filter screen 2 and the base bolt hole 15 on the base 3, and then penetrates through the spring gasket 6 and the nut 4 to be fixed, so that the hinge is completed. In the embodiment, the grate 1 is hinged to one side of the base 3, the filter screen 2 is hinged to the other side of the base 3, and the grate 1 can be opened firstly and then the filter screen 2 is opened, so that garbage and sundries in the pipeline can be cleaned conveniently.
During installation, the base 3 is embedded in the concrete 22, and the brick 21 for supporting is arranged below the base 3, so that the rainwater inlet device is integrally firm and is not easy to steal.
Referring to fig. 6, a first groove 19 for limiting the filter screen 2 and a second groove 20 for limiting the grate 1 are respectively arranged in the hollow structure of the base 3, the first groove 19 and the second groove 20 are positioned in the hollow structure to form a stepped structure, the grate 1 is arranged in the first groove 20, and the filter screen 2 is arranged in the second groove 20; wherein, referring to fig. 1 and 5, the first groove 19 is positioned above the second groove 20, and the opening size of the first groove 19 is larger than that of the second groove 20, so that the grate 1 is fixed above the filter screen, so that the rainwater is firstly discharged into the grate 1 and the filter screen 2 and then into the rainwater pipe 22, thereby enhancing the filtering effect.
Wherein, be equipped with a plurality of water holes 2 of crossing on the grate 1 and be arranged in filtering the rainwater great impurity, filter screen 2 central area is equipped with graticule mesh 10 and is used for filtering less impurity to realize dual filtration.
Furthermore, the grid 10 is arranged in the central area of the filter screen 2, and the contact area between the humid environment in the gully and the external environment can be reduced by only arranging the grid 10 in the central area of the filter screen 2, so that mosquitoes and insects bred due to the humidity at the bottom of the gully can be effectively blocked; meanwhile, as the grid net 10 is only arranged in the central area of the filter screen 2, when rainwater flows to the grid net 10 from the edge of the filter screen 2, sundries are stored on the periphery of the grid net 10, so that the sundries are prevented from flowing into the rainwater pipe 22 and are cleaned on the filter screen 2.
As the further scheme of this embodiment for the structure of inlet for stom water mouth portion is more stable, and the below of first recess 19 is equipped with and is used for spacing stopper 14 of filter screen 2 for accept upper filter screen 2 and play the fixed action.
Furthermore, one end of the grate 1 is provided with a first fixing block 17, one end of the filter screen 2 is provided with a second fixing block 18, the grate 1 is hinged to one side of the base 3 through the first fixing block 17, the filter screen 2 is hinged to the other side of the base 3 through the second fixing block 18, the filter screen 2 is hinged to one side of the base 3 through a fixing frame, the fixing frame can be conveniently replaced when the filter screen 2 is damaged, and the filter screen 2 can be detached and replaced by a new filter screen 2. The hinged end of the grate 1 on the base 3 is opposite to the hinged end of the filter screen 2 on the base 3, and the two sides are provided with the filter screens which are good in stability and convenient to open and clean.
When the rain-proof screen is used in concrete, when raining, ground rainwater flows to the grate 1, larger impurities in the rainwater are intercepted by the grate 1, smaller impurities flow to the grids 10 in the filter screen 2 through the water holes 8, and the grids 10 have smaller pores and can filter and intercept the small impurities; the rainwater filtered by the filter screen 2 flows into the rainwater inlet and then is discharged into the rainwater pipe 22, so that the rainwater is doubly filtered, and the rainwater inlet or the drainage pipeline is prevented from being blocked. Because the gutter inlet bottom is comparatively moist, breeds mosquito and mouse easily, the tiny so that can not a large amount of ponding of mesh 10 causes the gutter inlet bottom to moist to there is certain distance apart from the shaft bottom, so mesh 10 can effectively block mosquito and mouse. When the mouth of the gutter inlet needs to be cleaned, the grate 1 is only needed to be opened, then the filter screen 2 is opened, and sundries on the grate 1 and the filter screen 2 are cleaned, so that the gutter inlet is practical and convenient.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
