Abstract
The invention discloses a PVC gutter inlet cover which comprises a cover frame, a rainwater grate and a filter hopper. The rainwater grate is connected with the cover frame through a hinge. The filter hopper is arranged below the cover frame and the upper end edge of the filter hopper is placed inside the cover frame. Rectangular small holes are evenly formed in the rainwater grate. The filter hopper is of a reversed four-faced conic shape. The PVC gutter inlet cover is made of a PVC material which is good in waterproof performance and acid-base resistant performance, so that the PVC gutter inlet cover is good in rainwater scouring resistant performance and long in service life. Rainwater is separated from small sundries through the filter hopper, so that the rainwater is purified. The PVC gutter inlet cover is simple in structure and good in environment-friendly performance.
Description
Technical field
The present invention relates to a kind of road rain water flap, be specifically related to a kind of PVC rainwater flap, belong to hydraulic engineering and field of environment engineering.
Background technology
Existing road surface rainwater flap great majority are made of iron, through the long-term erosion of rainwater, can get rusty or be corroded by acid rain, so that be difficult to open.Current can be brought foreign material such as ground silt particle particle, leaf, plastic paper into when raining, the tradition inlet for stom water, the rainwater double-edged fine-toothed comb only is set up, play the big leaf of interception, polybag etc. than the effect of bigger material, to then not having interception function less than the silt particle particle in rainwater double-edged fine-toothed comb gap, little foreign material, can't reach the rainwater mud-water separation and purify, even the later stage can be stopped up drainage pipe, road ponding when making the rainy day brings constant for people's life.
Summary of the invention
The technical problem that solves: at the deficiencies in the prior art, the invention provides a kind of PVC rainwater flap, adopt the PVC material of acid and alkali-resistance to make, and be provided with filter, little foreign material are tackled practical environmental protection.
Technical scheme: the invention provides a kind of PVC rainwater flap, comprise cover frame, rainwater double-edged fine-toothed comb and cross pan, rainwater double-edged fine-toothed comb and cover frame are connected through the hinge, and cross pan and are located at the cover frame below, and upper end-face edge rests the cover frame inboard.Even distribution rectangle aperture on the rainwater double-edged fine-toothed comb is crossed four sides taper of pan.
Beneficial effect: a kind of PVC rainwater flap provided by the invention, adopt the PVC material of good waterproof performance, acid and alkali-resistance to make, anti-rainwater erosion is good, and the life-span is long; And realize separating of rainwater and little foreign material by crossing pan, realize the purification of rainwater, simple in structure, the feature of environmental protection is good.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of PVC rainwater flap;
Fig. 2 is the left TV structure schematic diagram of PVC rainwater flap;
Wherein, the 1-cover frame, 2-rainwater double-edged fine-toothed comb, 3-crosses pan.
The specific embodiment
A kind of PVC rainwater of the present invention flap comprises cover frame 1, rainwater double-edged fine-toothed comb 2 and crosses pan 3 that rainwater double-edged fine-toothed comb 2 and cover frame 1 are connected through the hinge, and cross pan 3 and are located at cover frame 1 below, and upper end-face edge rests cover frame 1 inboard.During rainfall, big particle, big leaf are tackled in the above by rainwater double-edged fine-toothed comb 2, and small particle, little leaf, silt particle entered pan 3 by rainwater double-edged fine-toothed comb 2, and the rainwater after the filtration enters drainage pipe by mistake pan 3 and flows away, regularly will cross pan and take out, remove the pollutant of the inside.
