Description
Technical Field
[0001] The utility model relates to a rainwater collecting and purifying device, in particular to a green building rainwater collecting and purifying device. Background Art
[0002] Green buildings encompass both man-made and natural environments when creating living environments. When planning a green environment, attention should be paid not only to landscape creation but also to the integration of environment and ecology, achieving holistic greening. This means taking a holistic approach, considering sustainability and naturalization. Sustainable applications encompass not only the building itself but also the surrounding natural environment, the efficient (ecological) use of domestic water, wastewater treatment and recovery, and the local climate.
[0003] However, in realizing this green vision, traditional rainwater collection systems are a critical area in need of improvement. Traditional rainwater collection systems often lack effective filtration mechanisms, resulting in the collected rainwater being laden with impurities and unable to be directly used for purposes such as watering plants. This not only limits the potential for rainwater reuse but also impacts the overall water conservation and environmental performance of green buildings.
[0004] Therefore, there is an urgent need for a green building rainwater collection and purification device to solve the technical problems existing in the above-mentioned prior art. Summary of the Invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.
[0028] like Figure 1As shown, a green building rainwater collection and purification device includes: a leg frame 1, a rain shield 2 and a loading rack 3; it is characterized in that the interior of the leg frame 1 is hollow, a guide plate 4 is provided on the top of the rain shield 2, and a guide frame 7 is provided around the rain shield 2. The guide frame 7 is provided with a guide groove 7.1, and the guide groove 7.1 has an opening connected to the interior of the leg frame 1. A water collecting tank 5 is provided at the bottom of the leg frame 1, and a guide pipe 1.4.1 for connecting the water collecting tank 5 and the interior of the leg portion is provided at the bottom of the leg portion; the leg portion includes a first pillar, a second pillar, a third pillar and a fourth pillar, and there are multiple loading racks 3, which are respectively fixed at the connection between the first pillar and the second pillar, the second pillar and the third pillar, and the third pillar and the fourth pillar.
[0029] like Figure 2 As shown, a gap is left between the rain shield 2 and the deflector 4, and a filter screen 6 is installed in the gap. The bottoms of the first column 1.1, the second column 1.2, and the third column 1.3 are all provided with grooves, and the tops of the second column 1.2, the third column 1.3, and the fourth column 1.4 are all provided with protrusions that match the grooves. The first column 1.1, the second column 1.2, the third column 1.3, and the fourth column 1.4 are connected in sequence.
[0030] like Figure 3 As shown, the interior of the second column 1.2 is equipped with a mesh assembly 1.2.1 for filtering particulate matter from rainwater. The interior of the third column 1.3 is equipped with a filter element 1.3.1 for filtering suspended matter from rainwater. A valve 5.1 is installed on one side of the water collection tank 5. The bottom cross-section of the water collection tank 5 is inclined, and the valve 5.1 is located at the bottom of the cross-section.
[0031] like Figure 4 As shown, the water collection tank 5 has notches 5.2 at each corner, into which one end of the diversion tube 1.4.1 is inserted. The diversion plates 4 are two in number, one end of each connected to the filter screen 6. The other two sides of the diversion plates 4 are connected to the rain shield 2. The diversion plates 4 are tilted at an angle of 25 to 45 degrees. Each leg frame 1 has at least one set of second columns 1.2 and at least one set of third columns 1.3.
[0032] When the present invention is used, first the first column 1.1, the second column 1.2, the third column 1.3 and the fourth column 1.4 are assembled and installed in sequence according to the positions of the protrusions and grooves to obtain the leg frame 1, and then the rain shield 2, the cargo rack 3 and the water collecting tank 5 are installed on the leg frame 1 in sequence. It should be further explained that the four corners of the bottom of the rain shield 2 are provided with mounting holes connected to the gap and the guide groove 7.1. During installation, the top of the first column 1.1 is embedded in the mounting hole, and at this time the mounting hole is connected to the hollow conduit of the leg frame 1. The cargo rack 3 is installed at the connection of the first column 1.1, the second column 1.2 and the third column 1.3 by a snap-fit connection. The water collecting tank 5 is installed at the bottom of the third column 1.3, and the guide pipe 1.4.1 at the third column 1.3 is inserted into the notch 5.2 of the water collecting tank 5, thereby completing the entire installation process.
[0033] When it rains, rainwater falls on the rain shield 2. Under the action of the guide plate 4, the rainwater flows into the leg frame 1 along the inclined direction of the guide plate 4. Before flowing in, the rainwater is filtered for the first time through the filter 6, thereby filtering out larger particles or other impurities in the rainwater.
[0034] The rainwater then passes through the grid group 1.2.1 in the support leg 1, filtering out some particulate impurities in the rainwater, thereby further ensuring the purity of the rainwater. The rainwater filtered by the grid group 1.2.1 is filtered again by the filter element 1.3.1. During this filtration process, the filter element 1.3.1 can filter out suspended matter, some organic matter, residual chlorine, odor, and some heavy metal ions in the rainwater, thereby further ensuring the purity of the rainwater.
[0035] After multiple filtrations, the rainwater is collected in the water collection tank 5. When the plants cultivated on the carrier 3 need to be watered, the water pipe only needs to be connected to the valve 5.1, and the rainwater in the water collection tank 5 will be released along the valve 5.1, thereby achieving watering.
[0036] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
