TECHNICAL FIELD

[0001] The utility model relates to the field of municipal rainwater drainage, in particular to a drainage structure for preventing rainwater drainage outlet from being blocked. BACKGROUND

[0002] In road construction, the underground of one side of the road is generally provided with a rainwater drainage system, and rainwater drainage facilities are also generally provided around a large open square. A drainage outlet is arranged on the road surface at intervals, and a rainwater grate is installed. The most common rainwater grate is currently made of cement composite material or cast iron in a rectangular shape, and has a slit on the top. The slit gap is generally about 25-30mm. Stones and other sundries are often clamped in the slit. The long grate is also prone to breakage. The grate is installed flat on the drainage outlet. Although it is simple and practical, leaves, branches and garbage bags can flow to the drainage outlet with the rainwater and gradually accumulate on the rainwater grate or block the slit of the rainwater grate. Eventually, the road surface water cannot be completely drained into the drainage system, or the drainage rate is low, resulting in a large amount of road surface water. Maintenance personnel have to check and clean the debris immediately in the rain. After the rain, the debris accumulated in the road surface rainwater outlet also affects the appearance. The existing invention 'Adjustable road side rainwater grate and installation method and process' and 'Anti-settlement anti-clogging easy-to-construct rainwater grate' have made some research on road surface rainwater drainage facilities and provided some feasible solutions. Although the above-mentioned solutions can solve some problems, in general, the components are complex and difficult to promote. SUMMARY

[0003] The utility model discloses to solve the technical problem that the leaves, branches and garbage bags can flow to the drainage outlet with the rainwater and gradually accumulate on the rainwater grate or block the slit of the rainwater grate of the current rainwater grate, and provide a drainage structure for preventing the rainwater drainage outlet from being blocked.

[0004] The utility model discloses the following technical scheme is adopted: a drainage structure for preventing rainwater drainage outlet from being blocked, including cast iron base that installs at the opening of the rainwater drainage outlet siltation pool top and the road surface grate that rotates and installs on the cast iron base, cast iron base and the top of road surface grate are flush with the road surface, still include the isolation grate and the isolation wall, the isolation grate rotates and installs on the cast iron base and is located below the road surface grate, the isolation wall sets up at the bottom of siltation pool and divides siltation pool into two parts of silt pool and sundry pool, and the outer side wall of silt pool is installed with the drainage pipe intercommunication drainage main pipeline, the isolation grate is obliquely arranged and covers the silt pool with the drainage pipe above, and the upper end of isolation grate is rotatably connected with the cast iron base, and the lower end is overlapped with the top of isolation wall.

[0005] Further, the road surface grate has an oval long hole, and the oval long hole is a reverse conical frustum hole structure with a narrow upper end and a wide lower end.

[0006] Further, the long axis of the elliptical long hole on the road grate is perpendicular to the road traffic direction.

[0007] Further, the isolation grate is made of hard plastic ceramic material and has slits.

[0008] Further, the cast iron base is square in structure, and the four sides extend wing plates with reinforcing rib plates.

[0009] Further, the cast iron base is square in structure, and the four sides extend wing plates with reinforcing rib plates.

[0010] The beneficial effects of the utility model are as follows:

[0011] At present, the common rainwater grate is generally rectangular, and the slit gap width is generally about 25-30mm. Stones, branches and other sundries are often clamped in the slit. The long grate bar is also easy to break. The road grate of the utility model has an elliptical long hole and a reverse conical hole structure. The elliptical upper hole short axis size of the road grate is widened to about 40mm, which can ensure that the road grate drainage hole is not blocked by sundries. Moreover, the elliptical reverse conical hole structure has a uniform transition shape, a strong arch-shaped bearing capacity, and can prevent breakage caused by stress concentration. The old grate has a strip-shaped long hole, and most of the installation directions are consistent with the road traffic direction. Once one of the grate ribs breaks, a large hole is formed, and the risk of wheel sinking is high when a bicycle passes through. The utility model has an elliptical hole, and the long axis line is perpendicular to the road traffic direction, which can prevent the wheels of a bicycle or an electric vehicle from sinking into the road grate slit hole. The old rainwater grate has only one protection. The utility model additionally provides a slanting slit sieve-shaped isolation grate made of hard plastic ceramic material. The surface is smooth and wear-resistant, which can prevent the grate from being blocked and ensure smooth drainage. Compared with other technologies, the design is simple, the installation is simple, and the troubleshooting is simple. BRIEF DESCRIPTION OF DRAWINGS
