Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a sponge city rainwater retention and purification device. Background Art

[0002] A sponge city is a city that can act like a sponge when faced with rainwater. It absorbs, stores, infiltrates and purifies water when there is sufficient rain, and releases and utilizes the stored water when needed. As an advanced urban stormwater management concept, sponge city aims to simulate the natural rainwater circulation system to collect, store, purify and utilize rainwater, so as to reduce the pressure on the urban drainage system, improve the city's flood control and drainage capabilities, and promote the sustainable use of water resources.

[0003] When collecting rainwater, some existing devices are prone to garbage and other impurities entering the collection system due to insufficient protective measures, causing blockage and reduced purification efficiency. At the same time, some devices lack effective monitoring and feedback mechanisms during the purification process, and cannot ensure that the purified water quality meets the use standards. This not only affects the use effect of the rainwater retention and purification device, but also increases the difficulty of subsequent maintenance and management. In order to solve these problems, the utility model proposes a sponge city rainwater retention and purification device. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology and to propose a sponge city rainwater retention and purification device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sponge city rainwater retention and purification device includes a floor, the interior of the floor is fixedly connected to a water collection seat, the lower surface of the water collection seat is fixedly connected to a filter box, one side of the lower surface of the filter box is fixedly connected to a first drain, the lower surface of the first drain is fixedly connected to a purification box, the lower surface of the purification box is fixedly connected to a second drain, the lower surface of the second drain is fixedly connected to a detection box, one side of the purification box is fixedly connected to a water storage tank, and one side of the detection box is fixedly connected to a conveying mechanism.

[0007] As a further improvement of the present invention, the conveying mechanism includes a water pump fixedly connected to one side of the water tank, the output end of the water pump is fixedly connected to a water supply pipe, the other end of the water supply pipe is fixedly connected to a tee pipe, one side of the tee pipe is fixedly connected to a circulation pipe, the other end of the circulation pipe is fixedly connected to the filter box, the other side of the tee pipe is fixedly connected to an output pipe, and the other end of the output pipe is fixedly connected to the water tank.

[0008] As a further improvement of the present invention, an electromagnetic conversion valve is fixedly connected to the surface of the three-way pipe.

[0009] As a further improvement of the present invention, a plurality of filter screens are fixedly connected to the interior of the filter box, and a plurality of activated carbon adsorption cores are fixedly connected to the interior of the purification box.

[0010] As a further improvement of the present invention, a protective cover is inserted into the upper surface of the water collecting seat.

[0011] As a further improvement of the present invention, a water quality monitor is fixedly connected to the upper surface of the detection box, and a drain pipe is fixedly connected to one side of the water storage tank.

[0012] Beneficial effects of the utility model:

[0013] By setting up a filter box and a purification box, when in use, the three-stage filtration system of the water collection seat, filter box and purification box realizes the initial filtration and deep purification of rainwater. The protective cover and water collection seat can prevent garbage and other impurities from entering the filtration system. The multiple filters in the filter box can effectively remove large particles of impurities in the rainwater, and the activated carbon adsorption core in the purification box can further adsorb harmful substances such as organic matter, residual chlorine, odor and some heavy metals in the water, significantly improving the cleanliness of rainwater. At the same time, a water quality monitor is integrated to monitor the quality of treated rainwater in real time to ensure that only rainwater that meets the standards is stored and used, effectively avoiding the storage of unqualified water quality and ensuring water quality safety and reliability of subsequent use.

[0014] By setting up a conveying mechanism, when in use, the water quality is tested by a water quality monitor. When it is detected that the rainwater quality is unqualified, the electromagnetic conversion valve is automatically started to return the unqualified rainwater to the filter box for re-filtration until the water quality meets the standard. The device improves the utilization rate of rainwater through the recycling treatment mechanism, reduces resource waste, and thus reasonably utilizes rainwater and stores it for use after effective treatment, increasing the practicality of the device.
