Description

Eddy effect anti-fouling rainwater grate structure Technical Field The utility model relates to the technical field of municipal drainage, in particular to a vortex effect anti-siltation rainwater grate structure. Background The gully refers to facilities for collecting surface water by a pipeline drainage system, and is generally arranged at the sides of a block, a square and a street as an inlet for surface runoff rainwater to flow into a drainage system so as to prevent the rainwater from leaving a passageway or causing ponding in roads and low-lying areas to obstruct traffic or damage the roads. The gully is provided with the comb board generally, and the comb board can play the effect of filtering and retaining to debris in the rivers, also can prevent simultaneously that vehicles, pedestrian etc. from falling into the gully. The most commonly used is a flat grate plate, which is usually installed on two sides of a road and needs to bear the weight of the automobile. Traditional municipal administration comb board is easily blocked by leaf, rubbish, leads to drainage efficiency to drop, and manual cleaning cost is very high. The prior art relies on a screen or interception, but requires frequent maintenance. Thus, a solution is needed. The foregoing is provided merely to facilitate an understanding of the principles of the utility model and is not intended to constitute an admission that the foregoing is of the closest prior art. Disclosure of utility model The utility model aims to solve the technical problem of providing the vortex effect anti-fouling rainwater grate structure, which is simple in structure, easy to produce and manufacture, and capable of carrying out solid-liquid separation on an inflow mixture when in use, so that the occurrence of clogging is avoided, the use effect is improved, and the daily maintenance cost is reduced. The technical scheme is that the vortex effect anti-fouling rainwater grate structure comprises a grate plate, a flow guide assembly and a collecting barrel, wherein the grate plate is arranged at a gully of a road, one end of the flow guide assembly is communicated with the grate plate and is used for receiving a solid-liquid mixture flowing into the grate plate, carrying out solid-liquid separation on the solid-liquid mixture and guiding the separated solid objects into the collecting barrel. Preferably, the flow guiding assembly comprises a funnel, wherein the top end of the funnel is communicated with the grid plate, and the bottom end of the funnel is communicated with the inlet of the collecting barrel. Preferably, the inner wall of the funnel is provided with a diversion trench, and the diversion trench is spirally distributed along the top inlet to the bottom outlet of the funnel. Preferably, the diversion trench is provided with a spray hole, and the outlet direction of the spray hole is tangential to the outer wall of the funnel. Preferably, the collecting barrel comprises an inner barrel and an outer barrel, wherein the top of the inner barrel is communicated with the bottom end of the funnel, the inner barrel is sleeved in the outer barrel, the surface of the inner barrel is provided with a filtering hole, and the surface of the outer barrel is provided with a drainage window. Preferably, an annular overflow port is arranged between the top end of the inner barrel and the bottom end of the funnel. Preferably, the filter screen comprises a filter screen cylinder, wherein the top of the filter screen cylinder is connected with the bottom end of the funnel and sleeved outside the outer barrel. The beneficial effects of the utility model are as follows: The rainwater grate structure provided by the utility model can be used for carrying out solid-liquid separation on objects flowing into the grate, so that the condition that the inlet is blocked due to the fact that the objects are deposited at the inlet of the grate is avoided. Meanwhile, the separated solid substances are collected in the collecting barrel, so that the later unified treatment is facilitated, and the convenience of use is improved.
