[0002] With increasing global water scarcity and growing environmental awareness, rainwater, as a precious freshwater resource, has received widespread attention for its collection and utilization. In urban construction and daily life, the direct discharge of large amounts of rainwater not only wastes water resources but also increases the burden on urban drainage systems, leading to problems such as urban flooding.

[0003] Existing technologies, such as the utility model with publication number CN 218779573 U, disclose a rainwater collection device, which includes a rainwater storage tank with an opening at the top and a rainwater delivery pipe connecting the opening of the tank to the roof, wherein the rainwater delivery pipe is detachably connected to the rainwater storage tank.

[0004] Existing technologies use rainwater harvesting devices with simple structures that collect rainwater through simple containers, lacking effective filtration and purification functions. This results in collected rainwater containing a large amount of impurities, silt, leaves, and pollutants, failing to meet diverse water needs and limiting the scope of rainwater reuse.

[0005] To address the above problems, this utility model provides an environmentally friendly and energy-saving rainwater collection device. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing rainwater collection devices have poor filtration and purification effects, resulting in collected rainwater containing a large amount of impurities, silt, leaves and pollutants. Therefore, this invention proposes an environmentally friendly and energy-saving rainwater collection device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly and energy-saving rainwater collection device, comprising a stable base plate, a collection and filtration mechanism, and a disinfection and collection mechanism, wherein the collection and filtration mechanism is fixedly connected to one side of the top of the stable base plate, and the disinfection and collection mechanism is fixedly connected to the other side of the top of the stable base plate, and the collection and filtration mechanism includes a filter assembly.

[0008] The filtration assembly includes a fine filtration module, which comprises a composite filter layer, a second activated carbon adsorption layer, and a third nanofiber filter membrane layer.

[0009] The composite filter layer, the activated carbon adsorption layer, and the nanofiber filter membrane layer are all connected by a connecting column. A sealing cover is fixedly connected to the top of the connecting column, and a sealing gasket is snapped into the bottom of the sealing cover. The filter assembly also includes a filter cylinder fixedly connected to the top center of the stable base plate. The fine filter module is snapped into the inside of the filter cylinder. Connecting bolts are threaded to both sides of the fine filter module, and the fine filter module is threaded into the inside of the filter cylinder through the connecting bolts.

[0010] Furthermore, a connecting pipe is fixedly connected to the top of the filter cylinder, one end of the connecting pipe is fixedly connected to the inside of the filter cylinder, and the other end of the connecting pipe is fixedly connected to a water pump body, with a suction pipe fixedly connected to the outer surface of the water pump body.

[0011] Furthermore, the collection and filtration mechanism also includes a rainwater collection cylinder fixedly connected to the other end of the suction pipe, and a rainwater collection port fixedly connected to the top of the rainwater collection cylinder.

[0012] Furthermore, the top of the rainwater collection port is provided with an insertion slot, and a primary filter screen is inserted into the inner wall of the insertion slot.

[0013] Furthermore, the disinfection collection mechanism includes a connecting water pipe fixedly connected to the bottom of the filter cylinder, a magnetic control valve fixedly connected to the outer surface of the connecting water pipe, and a rainwater storage cylinder fixedly connected to one end of the connecting water pipe.

[0014] Furthermore, a servo motor is fixedly connected to the top of the rainwater storage cylinder, a rotating stirring shaft is fixedly connected to the output end of the servo motor, and a rotating bearing is rotatably connected to the bottom of the rotating stirring shaft, with the outer surface of the bearing fitted into the inner bottom wall of the rainwater storage cylinder.

[0015] Furthermore, the inner wall of the rainwater storage cylinder is provided with ultraviolet disinfection devices at equal intervals, and a water quality detector is fixedly connected to the outer surface of the rainwater storage cylinder, with the water quality detectors symmetrically arranged on both sides of the rainwater storage cylinder.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, by setting up a two-layer activated carbon adsorption layer, a three-layer nanofiltration membrane layer, and a connecting column, combined with a combination of various treatment methods such as ultraviolet disinfection, high-precision filtration of rainwater and convenient component maintenance are achieved. The two-layer activated carbon adsorption layer uses coconut shell activated carbon with high adsorption performance, which can efficiently remove organic pollutants and odors from rainwater. The three-layer nanofiltration membrane layer uses nanofilm, which can intercept tiny particles and microorganisms, greatly improving water purity. The connecting column integrates the three-layer filtration structure into one unit, and with the connecting bolts, the fine filtration module and filter cartridge can be quickly disassembled and assembled, improving cleaning and replacement efficiency. This effectively solves the problem of difficult maintenance of filter components, reduces installation and maintenance costs, and ensures the normal operation of the device and the filtration and purification effect.

[0018] 2. In this utility model, the uniform disinfection and safe monitoring of rainwater are achieved by setting up a rotating stirring shaft, an ultraviolet disinfection device, and a water quality detector. The servo motor drives the rotating stirring shaft to rotate, causing the rainwater to circulate and mix fully and evenly in the storage tank. Multiple sets of evenly distributed ultraviolet disinfection devices avoid the dead zone problem of traditional static disinfection and improve sterilization efficiency. The water quality detector monitors water quality parameters in real time, and the data is transmitted to the control system. When the water quality does not meet the standards, the control system automatically starts the ultraviolet disinfection device and the stirring shaft for secondary disinfection to ensure the safety of rainwater reuse.

[0027] Please see Figure 1-6 This utility model provides a technical solution: an environmentally friendly and energy-saving rainwater collection device, including a stable base plate 1, a collection and filtration mechanism 2 and a disinfection and collection mechanism 3. The collection and filtration mechanism 2 is fixedly connected to one side of the top of the stable base plate 1, and the disinfection and collection mechanism 3 is fixedly connected to the other side of the top of the stable base plate 1. The collection and filtration mechanism 2 includes a filter assembly 21.

[0028] The following section will explain the specific setup and function of its collection and filtration mechanism 2 and disinfection and collection mechanism 3.

[0029] In this embodiment: the filter component 21 includes a fine filter module 211, which includes a composite filter layer 2111, a second activated carbon adsorption layer 2112, and a third nanofiber filter membrane layer 2113.

[0030] A connecting column 2114 is fixedly connected through the interior of a composite filter layer 2111, a second activated carbon adsorption layer 2112, and a third nanofiltration membrane layer 2113. A sealing cover plate 2115 is fixedly connected to the top of the connecting column 2114, and a sealing gasket 2116 is snapped into the bottom of the sealing cover plate 2115. The filter assembly 21 also includes a filter cylinder 212 fixedly connected to the top center of the stable base plate 1. A fine filtration module 211 is snapped into the interior of the filter cylinder 212. Connecting bolts 213 are threaded on both sides of the fine filtration module 211, and the fine filtration module 211 is threaded into the interior of the filter cylinder 212 through the connecting bolts 213.

[0031] The effects achieved by the above components are as follows: a three-stage progressive filtration structure consisting of a composite filter layer 2111, a second activated carbon adsorption layer 2112, and a third nanofiltration membrane layer 2113 enables rainwater to be purified step by step from coarse filtration to fine filtration. The first composite filter layer 2111 first intercepts larger particulate impurities, reducing the load on subsequent adsorption and fine filtration. The second activated carbon adsorption layer 2112 deeply removes organic pollutants and odors, improving the sensory properties of rainwater. The third nanofiltration membrane layer 2113 intercepts tiny particles, bacteria, etc., significantly improving water purity.

[0032] The connecting column 2114 firmly integrates the three filter layers into one, ensuring the stability and non-displacement of each layer during the filtration process. The sealing cover 2115 and the sealing gasket 2116 cooperate to effectively prevent rainwater from leaking through the gap between the fine filter module 211 and the filter cartridge 212, avoiding unfiltered rainwater from mixing with filtered rainwater and ensuring the filtration effect. The filter cartridge 212 provides an installation carrier and protective shell for the fine filter module 211. The connecting bolt 213 enables quick assembly and disassembly of the two. Compared with the traditional fixed connection method, it greatly shortens the cleaning and replacement time of the filter module, improves the convenience of maintenance, and ensures the sealing and stability of the connection.

[0033] Specifically, a connecting pipe 214 is fixedly connected to the top of the filter cylinder 212. One end of the connecting pipe 214 is fixedly connected to the inside of the filter cylinder 212, and the other end of the connecting pipe 214 is fixedly connected to a water pump body 215. A suction pipe 216 is fixedly connected to the outer surface of the water pump body 215.

[0034] The above components achieve the following effects: the connecting pipe 214 serves as a channel for rainwater transport, enabling the connection between the pump body 215 and the filter cylinder 212. The pump body 215 can automatically adjust its power and pumping volume according to the amount of rainwater collected. When a large amount of rainwater is collected, the power is automatically increased to accelerate the pumping speed and prevent the rainwater collection cylinder 22 from overflowing. The suction pipe 216 connects the rainwater collection cylinder 22 and the pump body 215, providing a transport path for rainwater to enter the filter assembly 21. The three components work together to construct a stable and controllable rainwater transport system, ensuring that rainwater can enter the filtration process efficiently and in an orderly manner.

[0035] Specifically, the collection and filtration mechanism 2 also includes a rainwater collection cylinder 22 fixedly connected to the other end of the suction pipe 216, and a rainwater collection port 23 fixedly connected to the top of the rainwater collection cylinder 22.

[0036] The effects achieved by the above components are as follows: the rainwater collection port 23 adopts a funnel-shaped structure, which significantly expands the rainwater receiving area and can efficiently collect rainwater from roofs, ground and other areas, improving rainwater collection efficiency. The rainwater collection cylinder 22 serves as a temporary storage container for rainwater. Its large volume can buffer the rainwater flow during peak rainfall periods, preventing rainwater from overflowing due to excessive instantaneous flow. At the same time, it provides a stable water source for subsequent filtration and transportation. The two work together to achieve efficient collection and temporary storage of rainwater, providing a basic guarantee for the continuous operation of the entire device.

[0037] Specifically, the top of the rainwater collection port 23 is provided with an insertion slot 24, and a primary filter screen 25 is inserted into the inner wall of the insertion slot 24.

[0038] The effects achieved by the above components are as follows: the primary filter screen 25 can directly intercept larger impurities such as leaves, branches, stones, and plastic bottles in rainwater, preventing these impurities from entering the rainwater collection cylinder 22 and clogging the suction pipe 216 or damaging the water pump body 215. This effectively protects the normal operation of subsequent core components and reduces the risk of equipment failure. The design of the insertion slot 24 makes the primary filter screen 25 easy to insert and remove. Users can quickly remove the filter screen for cleaning or replacement without the need for tools, making the operation convenient. In addition, the rubber sealing strip on the inner wall of the slot can prevent rainwater from leaking through the gaps, ensuring that all rainwater is filtered by the filter screen before entering the collection cylinder.

[0039] Specifically, the disinfection collection mechanism 3 includes a connecting water pipe 31 fixedly connected to the bottom of the filter cylinder 212, a magnetic control valve 32 fixedly connected to the outer surface of the connecting water pipe 31, and a rainwater storage cylinder 33 fixedly connected to one end of the connecting water pipe 31.

[0040] The above components achieve the following effects: the connecting water pipe 31 transports the filtered rainwater from the filter cylinder 212 to the rainwater storage cylinder 33, forming a connecting bridge between the filtration and storage links; the magnetic control valve 32 can be remotely controlled by the control system to open and close; when the water level in the rainwater storage cylinder 33 reaches the upper limit, the valve automatically closes to prevent rainwater from overflowing; the rainwater storage cylinder 33 provides long-term storage space for the purified rainwater and allows for reasonable water usage. Together, these three components constitute a rainwater transportation, control, and storage system, ensuring that the filtered rainwater can be safely stored and used as needed.

[0041] Specifically, a servo motor 34 is fixedly connected to the top of the rainwater storage cylinder 33, a rotating stirring shaft 35 is fixedly connected to the output end of the servo motor 34, and a rotating bearing 36 is rotatably connected to the bottom of the rotating stirring shaft 35. The outer surface of the bearing 36 is fitted into the inner bottom wall of the rainwater storage cylinder 33.

[0042] The effects achieved by the above components are as follows: the servo motor 34 provides stable power to the rotating stirring shaft 35, and the speed can be adjusted according to the needs, driving the stirring blades to rotate, so that the rainwater in the rainwater storage tank 33 forms a circulating flow. This flow can avoid the sedimentation of impurities and water stratification caused by the rainwater sitting for a long time. At the same time, it can make the rainwater fully contact the ultraviolet rays of the subsequent ultraviolet disinfection device 37, eliminating disinfection dead corners. The rotating bearing 36 effectively reduces the frictional resistance between the rotating stirring shaft 35 and the bottom wall of the storage tank when it rotates, reduces motor energy consumption, and ensures that the stirring shaft runs smoothly without shaking, extending the service life of the motor and the stirring shaft, and ensuring that the stirring function is stable and reliable.

[0043] Specifically, the inner wall of the rainwater storage cylinder 33 is provided with ultraviolet disinfection devices 37 at equal intervals, and the outer surface of the rainwater storage cylinder 33 is fixedly connected with a water quality detector 38, which is symmetrically arranged on both sides of the rainwater storage cylinder 33.

[0044] The aforementioned components achieve the following effects: the ultraviolet disinfection device 37 can efficiently destroy the DNA structure of bacteria and viruses in rainwater, achieving sterilization and disinfection without the need for added chemical agents, avoiding secondary pollution and ensuring the safety of rainwater reuse. The multi-group, equally spaced design covers all areas within the storage tank. Combined with the stirring action of the rotating stirring shaft 35, it achieves all-round, no-dead-angle disinfection of rainwater, significantly improving sterilization efficiency. Water quality detectors 38 are symmetrically arranged on both sides of the storage tank, comprehensively and in real-time monitoring key water quality parameters such as pH value, turbidity, and residual chlorine, with data transmitted to the control system in real time. When water quality is detected to be substandard, the control system automatically activates the ultraviolet disinfection device 37 and the rotating stirring shaft 35 for secondary purification, forming a closed-loop water quality assurance system to ensure that the output rainwater always meets reuse standards.

[0045] Working principle: When using this environmentally friendly and energy-saving rainwater collection device, during rainfall, rainwater is collected through the funnel-shaped rainwater collection port 23. First, the primary filter screen 25 intercepts large impurities such as leaves and stones. The filtered rainwater flows into the rainwater collection cylinder 22 for temporary storage.

[0046] Subsequently, the water pump 215 is started, and the rainwater in the rainwater collection cylinder 22 is transported through the suction pipe 216 to the fine filtration module 211 in the filter cylinder 212 via the connecting pipe 214. The rainwater passes through a composite filter layer 2111 to filter large particles of mud and sand, a second activated carbon adsorption layer 2112 to remove odors and organic pollutants, and a third nano-filtration membrane layer 2113 to trap tiny particles and microorganisms, completing three-stage purification.

[0047] The purified rainwater is transported to the rainwater storage tank 33 through the connecting water pipe 31. The magnetic control valve 32 automatically adjusts its opening and closing state according to the liquid level in the storage tank. During the storage process, the servo motor 34 drives the rotating stirring shaft 35 to rotate, so that the rainwater circulates. In conjunction with the multiple sets of ultraviolet disinfection devices 37 on the inner wall, all-round disinfection is carried out. The water quality detector 38 monitors the rainwater quality in real time. If the water quality does not meet the standards, the control system automatically starts the secondary disinfection process. If the water quality meets the standards, the rainwater can be taken out through the external pipe.

[0048] During maintenance, the primary filter screen 25 can be cleaned by plugging and unplugging it, and the fine filter module 211 can be removed and the filter layer replaced by loosening the connecting bolt 213. The operation is convenient. The whole process realizes efficient collection, graded filtration, intelligent disinfection and safe storage of rainwater, and has the dual advantages of environmental protection and energy saving as well as convenience and practicality.
