Irrigation system is collected to town road rainwater

Technical Field

The utility model belongs to the technical field of the technique of municipal facilities and specifically relates to an irrigation system is collected to town road rainwater.

Background

At present, with the increase of urban population, the water consumption of cities is greatly increased, and particularly some northern cities are easy to fall into the condition of water supply shortage.

The irrigation of the green belt beside the municipal road needs municipal water supply, the water consumption of the green belt beside the municipal road for irrigation accounts for the important component of the water consumption of the city, and in order to prevent the surface water accumulation of the municipal road in rainy days, the municipal road needs drainage construction to drain away the rainwater on the surface.

In order to effectively improve the utilization rate of water resources, people now propose the concept of collecting rainwater on municipal roads for green belt irrigation.

The above prior art solutions have the following drawbacks:

however, solid impurities such as leaves, garbage, silt, broken stones and the like are often mixed in rainwater on municipal roads, and the solid impurities can easily damage the environment of green belts and the growth of plants, so that the solid impurities in the rainwater are usually required to be removed by filtering after the rainwater is collected.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, one of the purposes of the utility model is to provide an irrigation system is collected to town road rainwater, it has the effect of difficult jam.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides an irrigation system is collected to town road rainwater, is including being located the catchment canal between town road and the greenbelt, the catchment canal bottom runs through there is the inlet hole, the header tank has been buried underground to the catchment canal below, inlet hole intercommunication has the collector pipe that runs through the header tank top, the collector pipe internal rotation is connected with the pivot, the vertical setting of pivot, a plurality of flabellums of fixedly connected with in the pivot, the flabellum is located the collector pipe, inlet hole one end fixedly connected with water filtering barrel is kept away from in the pivot, water filtering barrel leaves the clearance with the header tank inner wall, it has a plurality of water filtering holes to distribute on the water filtering barrel, the mouth of pipe that the inlet hole was kept away from to the collector pipe is.

By adopting the technical scheme, in rainy days, solid impurities such as leaves, garbage, silt, broken stones and the like mixed in rainwater on a municipal road enter the water collecting pipe from the water inlet hole at the bottom of the water collecting channel, rainwater flows downwards to impact the fan blades in the water collecting pipe, so that the fan blades are driven to rotate around the axis of the rotating shaft and further drive the rotating shaft to rotate, and then the rotating shaft drives the water filtering barrel to rotate, so that the water filtering barrel drives the solid impurities in the water filtering barrel to do circular motion around the axis of the rotating shaft in the rotating process, further the solid impurities are subjected to centrifugal force far away from the rotating shaft, so that the solid impurities are accumulated towards the edge of the water filtering barrel due to the centrifugal force, the bottom of the water filtering barrel is not easy to be full of the solid;

meanwhile, the rainwater rotates along with the filtering bucket in the filtering bucket, so that the rainwater is acted by centrifugal force, and is thrown out of the filtering bucket under the action of the centrifugal force, and the efficiency of the rainwater permeating through the filtering bucket is improved;
