Rainwater storage and supply device for sponge urban ecological gardening

Abstract

The invention relates to a rainwater storage and supply device for sponge urban ecological gardening. The rainwater storage and supply device comprises a water guide well and a water storage well communicated with the water guide well, a dirt stopping grid is arranged at the position of the upper end of the water guide well and is of a suspended structure, a well lid is arranged on the upper portion of the water guide well, water guide ports are evenly disposed in the well lid, the bottom of the water guide well is provided with a water seepage device, the upper portion of the water seepage device is provided with a water seepage conduit, the lower end of the water seepage conduit is connected with a water seepage disc, the periphery of the water seepage disc is provided with water seepage holes, and a communicating pipe is arranged between the water guide well and the water storage well. A liquid level sensor is arranged in the water storage well, the bottom of the water storage well is provided with a draining pump, the draining pump is connected with a drain pipe, the drain pipe is connected with a water outlet pipe A and a water outlet pipe B, and the water outlet pipe A and the water outlet pipe B are provided with a solenoid valve A and a solenoid valve B respectively. The rainwater storage and supply device has the advantages of being high in water permeability, quickly dredging accumulated water, storing water when the rainfall is heavy and performing dedusting irrigation by utilizing the accumulated water.

Description

technical field [0001] The invention belongs to the technical field of urban rainwater systems, and in particular relates to a rainwater storage and supply device for sponge city ecological gardening. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in terms of adapting to environmental changes and responding to natural disasters. use. Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources And ecological environment protection, in the current urban construction process, due to urban construction, urban road surface hardening and other reasons have affected the infiltration of rainwater, resulting in the phenomenon that every heavy rain will be wat...
