Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of road rain water defecator, the mouth of pipe at the rainwater upstream end of rainwater arm 5 arranges drainage screen, and rainwater arm connects inlet for stom water and inspection shaft.Drainage screen is generally on same plane, and drainage screen is made up of horizontally set and vertically arranged rib, and rib is divided into main rib 2 and secondary rib 1, and the more secondary rib of main rib is thick, and main rib constitutes drainage screen skeleton.Drainage screen is completely covered the mouth of pipe or covers middle part and the bottom of the mouth of pipe.Drainage screen covers middle part and the bottom of the mouth of pipe, and as shown in Figure 4, mouth of pipe top does not set drainage screen, it is simple to when rainfall is big by substantial amounts of rainwater.
For the fixed form of drainage screen, a kind of fixed form is: the outer rim of drainage screen arranges engaging lug 4, and engaging lug can be the part of ring plate, packing ring etc.Engaging lug and main rib are welded and fixed, and engaging lug arranges expansion bolt perforating, and expansion bolt 3 is arranged in bolt perforating and is fixed on by drainage screen on the basis that the rainwater arm mouth of pipe is peripheral.This fixed form is the non-dismountable connection of drainage screen.
Another kind of fixed form is: the outer rim of drainage screen arranges rectangle frame, the left side of the rainwater arm mouth of pipe arranges the left chute in the U-shaped cross section that above-below direction extends, the right side of the rainwater arm mouth of pipe arranges the right rail in the U-shaped cross section that above-below direction extends, left chute and right rail opening are oppositely arranged, the left side of rectangle frame and the right are inserted in left chute and right rail respectively, it is achieved fixing of drainage screen.This fixed form is that drainage screen removably connects, and when needs are changed or safeguard drainage screen, only need to be drawn upwardly out changing by drainage screen so that filter screen replacement is convenient.
As it is shown in figure 5, a kind of road rain water defecator, the mouth of pipe at the rainwater upstream end of rainwater arm 5 arranges drainage screen, and rainwater arm connects inlet for stom water and inspection shaft.Drainage screen includes main filter screen and lays respectively at left side drainage screen and the right side drainage screen of main filter screen both sides, or, drainage screen includes main filter screen, left side drainage screen, right side drainage screen and upside drainage screen, and left side drainage screen, right side drainage screen and upside drainage screen lay respectively on the left of main filter screen, right side and upside.Main filter screen is generally on same plane, and plane residing for main filter screen and the rainwater arm mouth of pipe has the gap of plane residing for angle, main filter screen and the rainwater arm mouth of pipe and is gradually reduced from top to bottom.Main filter screen is made up of horizontally set and vertically arranged rib, and rib is divided into main rib and secondary rib, and the more secondary rib of main rib is thick, and main rib constitutes main filter screen skeleton.Main filter screen projection in plane residing for the rainwater arm mouth of pipe is completely covered the mouth of pipe.The relative rainwater arm mouth of pipe of main filter screen of this drainage screen tilts upward setting, it is possible to alleviate foreign material attachment on drainage screen, reduces clearing times.
For the fixed form of drainage screen, a kind of fixed form is: the edge of left side drainage screen and right side drainage screen is welded and fixed engaging lug, and engaging lug can be the part of ring plate, packing ring etc.Arranging expansion bolt perforating on engaging lug, expansion bolt is arranged in bolt perforating and is fixed on by drainage screen on the basis that the rainwater arm mouth of pipe is peripheral.
Another kind of fixed form is: the left side of the rainwater arm mouth of pipe arranges the left chute in the U-shaped cross section that above-below direction extends, the right side of the rainwater arm mouth of pipe arranges the right rail in the U-shaped cross section that above-below direction extends, left chute and right rail opening are oppositely arranged, and the flanging of left side drainage screen and right side drainage screen inserts in left chute and right rail respectively.
