Description

Technical Field

[0001] The utility model relates to the technical field of road construction drainage, in particular to an anti-blocking rainwater grate system. Background Art

[0002] During road construction, when rainwater drainage projects are to be carried out, rainwater grates are used to discharge rainwater. Traditional rainwater grates (cast iron manhole covers for rainwater drainage outlets) have large openings, and a large amount of garbage, leaves, tree roots and other debris will flow into the rainwater well through the gaps in the grate manhole covers, blocking the rainwater drainage pipes. At present, in order to prevent blockage, the existing technology requires the installation of a separate collection net or collection basin at the drainage well mouth (under the rainwater grate). This collection net or collection basin needs to be cleaned regularly or on time, otherwise too much garbage or debris will accumulate and block the drainage function of the rainwater outlet. Moreover, this collection device needs to be installed separately for each rainwater outlet, which is time-consuming and labor-intensive, increases costs, and has no obvious effect. In the later maintenance and use, a large amount of manpower and material resources are required to realize its function. Summary of the invention

[0003] In view of this, the utility model proposes an anti-blocking rainwater grate system, including a rainwater grate, a filter net, a hook and a buckle; the filter net is laid flat on the rainwater grate and can cover all opening gaps on the rainwater grate, the periphery of the filter net is connected to the rainwater grate through the buckle arranged thereon, and a plurality of hooks are provided on the periphery of the rainwater grate corresponding to the buckle, and the buckle can clamp the hook, so that the filter net is clamped on the rainwater grate.

[0004] Preferably, the buckle is connected to the edge of the filter screen via a connected spring.

[0005] Preferably, the edge of the filter is also fixed by a U-shaped auxiliary clamp, and a connecting rope is provided on the first side of the U-shaped auxiliary clamp, and the connecting rope can bind the edge of the filter. The U-shaped auxiliary clamp can be clamped on the edge frame structure of the rain grate, thereby auxiliary fixing the filter.

[0006] Preferably, the hooks include four and are disposed at the four corners of the rain grate, and the buckles also include four corresponding ones and are disposed at the four corners of the filter net.

[0007] Preferably, a plurality of the U-shaped auxiliary clamps are provided corresponding to the edge frames of the rainwater grate.

[0008] The utility model provides an anti-blocking rainwater grate system with the following advantages: the system has an anti-blocking function, does not require a separate storage device to be installed after installation, and does not require manual regular cleaning. The branches, leaves, garbage and debris that flow through with the rainwater are the same as ordinary debris on the road surface. They only need to be cleaned by the normal working of the sweeper, and there is no need to manually open the manhole cover for separate cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
