A rainwater collection device for sponge city

Abstract

The invention relates to a rainwater collection device for a sponge city, which includes a maintenance frame and a maintenance drive assembly. The maintenance frame is installed on a base. The maintenance drive assembly includes a maintenance drive and a maintenance track. The maintenance track is provided with a second a preset position and a second preset position, the maintenance driving assembly is used to drive the maintenance frame on the base to move between the first preset position and the second preset position; the water filter The collection device includes a water filter frame and a linked sand-foundry mechanism. The sand-foundry component is linked with the green plant maintenance frame, and can regularly extend outward from the bottom of the filter tank to receive photosynthesis. The side linkage of the maintenance frame is in the process of moving out The sand turning mechanism will force the sand and gravel in the water filter tank to turn the sand, so that it is always in the state of gap filtration, which can effectively prevent the filter gap between the sand and gravel from being blocked due to impurities mixed in the gap during filtration, so the structure of the water filter tank is reasonable.

Description

technical field [0001] The invention relates to a rainwater collection device, more specifically, to a rainwater collection device for a sponge city. Background technique [0002] Rainwater harvesting is the process of collecting rainwater and reusing water that meets certain water quality indicators after treatment. Rainwater harvesting plays a dominant role in the management of sponge cities. [0003] The rainwater collection devices used in the sponge city environment are mostly trough-type rainwater collection cabins, which collect the rainwater and use advanced filtering equipment to purify and treat it, and then put it into use or discharge it up to standard. [0004] When planting green plants in an urban environment, using the above-mentioned high-end method to filter rainwater before watering involves more filtering equipment, high installation costs, and inconvenient maintenance when it is in a higher position. The method of filtering rainwater with low-cost sand p...

[0004] When planting green plants in an urban environment, using the above-mentioned high-end method to filter rainwater before watering involves more filtering equipment, high installation costs, and inconvenient maintenance when it is in a higher position. The method of filtering rainwater with low-cost sand particles, Because the sand particles are in a static state for a long time, the impurities filtered in the sand layer will easily block the filter gaps between the sand particles and affect the filtering effect. However, in actual use, the surrounding environment cannot be detected so that the planting frame can realize automatic control
