Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering, in particular to a municipal road drainage structure. Background Art

[0002] The municipal road drainage structure is an engineering facility structure that treats and removes urban sewage and rainwater. It is an integral part of urban public facilities and is very important in the urban construction planning process.

[0003] At present, when constructing the existing municipal road drainage structure, drainage ditches are usually excavated inside the municipal road, and the drainage ditches are connected to the municipal drainage system. Curbs are set on both sides of the road, and drainage outlets are opened on the side of the curb facing the road. The drainage outlets are connected to the drainage ditches, and grilles are installed at the drainage outlets. On rainy days, the accumulated water on the municipal road converges to the drainage outlets, and after being filtered by the grilles, the large impurities carried can be filtered out, and then discharged into the drainage ditches, and finally discharged to the municipal drainage structure, thereby preventing water accumulation on the road and ensuring road safety.

[0004] However, due to the large pores of the grille, it can only filter out large impurities, so small impurities will still enter the drain with rainwater, especially organic matter such as food residues, plant materials, animal waste, etc., whose particles are small and cannot be filtered by the grille. Once they enter the drain, they will accumulate in large quantities and attach to the bottom of the drain because they are not collected in an orderly manner. Due to the suitable environmental conditions inside the drain, these organic matter will cause corruption, thereby producing foul-smelling gases. Summary of the invention

[0005] The purpose of the present invention is to provide a municipal road drainage structure in order to solve the above-mentioned problems.

[0006] The present invention achieves the above-mentioned purpose through the following technical scheme: a municipal road drainage structure, including a road body, a drainage ditch and a slag collecting trough are opened inside the road body, a filter plate is arranged at the opening of the drainage ditch, a plurality of filter holes are opened on the filter plate, a slag transport device is arranged inside the drainage ditch, the slag transport device includes a frame, a conveyor mesh belt and a driving mechanism for driving the conveyor mesh belt to circulate are arranged on the frame, a plurality of meshes are arranged on the conveyor mesh belt, the size of the meshes is smaller than the size of the filter holes, the conveyor mesh belt includes an input end and an output end, the input end is located below the filter plate, and the output end faces the inside of the slag collecting trough.

[0008] As a further configuration of the present invention, the active roller and the driven roller are both connected with a plurality of sprockets, and the conveyor belt comprises a plurality of chains, which are meshedly connected with the sprockets.

[0009] As a further configuration of the present invention, a flushing device is provided on the frame, and the flushing device includes a casing fixedly mounted on the frame, the conveyor belt passes through the casing, and a water spraying mechanism is provided inside the casing.

[0016] In summary, the present invention has the following beneficial effects: The present invention can filter out large impurities carried in rainwater through the initial filtration of the filter plate, and then enter the drain ditch through the filter hole. The rainwater needs to be filtered through the secondary filtration of the conveyor mesh belt to filter out small impurities carried in the rainwater, and then flow into the bottom of the drain ditch through the mesh to be collected, and finally discharged to the municipal drainage system. Since the rainwater has undergone double filtration, the impurities can be effectively filtered out, and a large amount of impurities can be avoided from entering the drain ditch. After the small impurities are filtered out by the conveyor mesh belt, they will accumulate on the surface of the conveyor mesh belt. The conveyor mesh belt can be driven to circulate by the driving mechanism, which can drive the small impurities to be transported from the input end to the output end. When the small impurities are transported to the output end, they can fall into the slag collecting tank and accumulate, so that the small impurities can be collected in an orderly manner, which is convenient for centralized cleaning, thereby avoiding a large amount of impurities accumulating and adhering to the bottom of the drain ditch, reducing the generation of odor, and ensuring the use effect of the drainage structure.
