Technical Field

[0003] The embodiments of the present application relate to the field of water recycling, and in particular to a water circulation device and a water circulation system. Background Art

[0004] Traditional road construction relies on ordinary brick or concrete paving. These materials don't absorb or seep water during rain, making the road surface slippery. Rainwater drainage relies on urban drainage pipes. Heavy rain, stormwater, high drainage volumes, and clogged drainage pools often cause road waterlogging and even waterlogging. Furthermore, rainwater flows directly into urban drainage pipes, resulting in low utilization of rainwater (a freshwater resource) on urban roads.

[0005] The concept of a sponge city was proposed to address issues like drainage and water storage in rainy urban areas. This concept involves building a city like a sponge, capable of absorbing, storing, infiltrating, and purifying water. This approach mitigates natural disasters caused by rainwater, making it a water-resilient city that can be expanded and contracted.

[0006] However, the construction of water storage equipment requires the occupation of precious land resources in the city and is easily idle in seasons with low rainfall, resulting in waste. Summary of the Invention

[0007] The main technical problem solved by the embodiments of the present application is to provide a water circulation device and a water circulation system, which can fully utilize the existing space to collect and utilize rainwater, increase the utilization rate of fresh water resources without occupying additional space, and reduce the occurrence of urban waterlogging.

[0008] To solve the above technical problems, in a first aspect, embodiments of the present application provide a water circulation system for being arranged in a drainage channel and below a drainage channel cover, comprising:

[0009] a water reservoir for collecting water filtered through the drain cover, having opposing first and second side walls;

[0010] A first connecting port and a second connecting port are respectively provided at corresponding positions of the first side wall and the second side wall, and are used to be connected to a connecting pipe to connect a plurality of water reservoirs so that the collected water flows between the water reservoirs;

[0011] a drain port, provided on the bottom wall of the water reservoir, for discharging collected water;

[0012] A drain plug is used in conjunction with the drain outlet to control the discharge of the collected water.

[0013] In some embodiments, the number of the first connection port and the number of the second connection port are both two.

[0014] In some embodiments, the water storage further includes a third side wall and a fourth side wall, and the first side wall, the second side wall, the third side wall and the fourth side wall form a storage space for storing the collected water.

[0015] In some embodiments, a water cleaning agent is disposed in the water reservoir.

[0016] To solve the above technical problems, in a second aspect, an embodiment of the present application provides a water circulation system, comprising:

[0017] drainage channels;

[0018] A drain cover, used to cover the drain and filter the water flowing into the drain;

[0019] Multiple water circulation devices as described in the first aspect above are used to collect water filtered by the drainage channel cover, and the water circulation devices are connected through connecting pipes.

[0020] In some embodiments, the shape of the water reservoir is adapted to the shape of the drain cover and the available space in the drain.

[0021] In some embodiments, the drain cover is a detachable structure and can be removed relative to the drain.

[0022] In some embodiments, the drainage channel cover includes a plate body formed by stacking multiple hydrophobic filling layers, wherein the hydrophobic filling layers have a large number of gaps, and the gaps constitute drainage channels.

[0023] In some embodiments, a drainage groove is provided at the bottom of the plate.

[0024] In some embodiments, the water circulation system further comprises:

[0025] A spray gun is provided for cleaning using the collected water in the water reservoir.

[0026] The beneficial effects of the embodiments of the present application are as follows: Unlike the prior art, the embodiments of the present application provide a water circulation device disposed within a drainage channel and below a drainage channel cover. Water is collected through a water reservoir within the water circulation device. Multiple water reservoirs are connected and the collected water flows through a first connection port and a second connection port.

In addition, although the functional modules are divided in the device schematic and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order than the module division in the device or the order in the flow chart. In addition, the words "first", "second", "third", etc. used herein do not limit the data and execution order, but only distinguish between the same items or similar items with basically the same functions and effects.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0035] In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0036] As shown in Figure 1, an embodiment of the present application provides a water circulation device, which is arranged in a drain channel and located below the drain channel cover. It includes a water storage tank 11, a first connection port 12, a second connection port 13, a drain port 14 and a drain plug 15.

[0037] The water storage 11 is used to collect water filtered through the drain cover, and has a first side wall and a second side wall opposite to each other.

[0038] In some embodiments, the water storage 11 further includes a third side wall and a fourth side wall, and the first side wall, the second side wall, the third side wall and the fourth side wall form a storage space for storing the collected water.

[0039] The size and shape of the water reservoir are not fixed and can be customized according to usage needs so that the water reservoir can be used in conjunction with the drain cover and can match the size of the drain to be placed, or meet other specific requirements.

[0040] The water reservoir may be made of any durable material, such as stainless steel, aluminum, plexiglass, polyvinyl chloride, and the like.

[0041] The water collected by the water storage device can have multiple uses, such as cleaning roads or irrigating lawns and green plants. It can also be transferred to other containers for further processing and use, achieving the effect of water recycling and reuse, and improving the utilization rate of fresh water resources.

[0042] The water reservoir 11 is provided with a first connection port 12 and a second connection port 13, which are respectively located at corresponding positions on the first side wall and the second side wall. Multiple water reservoirs can be connected by connecting pipes to the connection ports. One end of a water reservoir can be connected to another water reservoir, or both ends of a water reservoir can be connected to another water reservoir. Once multiple water reservoirs are connected, the water collected in each water reservoir can circulate through the connection ports and the connection pipes, allowing the collected water to be centrally used. If the water volume in a particular water reservoir is excessive, the collected water will be diverted to other water reservoirs, thereby improving the usability of the water circulation device. When connection to other water reservoirs is not required, the connection port can be sealed with a sealing cap to prevent the collected water from flowing out of the connection port.

[0043] When multiple water reservoirs are connected via connecting pipes, they form a chain of reservoirs. Water from the entire chain can be used at any one of these reservoirs through the siphon effect. This large volume of available water allows for a wider range of uses, increasing the efficiency of the collected water. The siphon effect is caused by the attraction and potential energy differences between liquid molecules. This pressure difference in the water column causes water to rise and then flow to a lower level. Because the water surface at the pipe outlet is subject to different atmospheric pressures, water will flow from the higher pressure side to the lower pressure side until the atmospheric pressure on both sides equalizes, the water level within the container becomes the same, and the water stops flowing. Using the siphon effect, water can be quickly pumped out of a container.

[0044] In some embodiments, the number of the first connection port and the number of the second connection port are both two, so that the collected water can flow faster between the water storages.

[0045] The bottom wall of the water storage 11 is provided with a drain port 14 for draining the collected water. A drain plug 15 is used in conjunction with the drain port 14. When collecting water, the drain plug 15 is used to close the drain port 14. When the collected water needs to be drained, the drain plug 15 is removed to drain the collected water in the water storage.

[0046] In some embodiments, a water cleaning agent is disposed in the water reservoir.

[0047] In order to better utilize the collected water, water cleaning agents, such as water purifiers, disinfectants or sterilizers, may be added to the water storage device. During use, one or more water cleaning agents may be added as needed.

[0048] Water purifiers are agents added to water to react with other impurities. Their primary purpose is to purify the water. Commonly used water purifiers include polyaluminum chloride, polyaluminum ferric chloride, basic aluminum chloride, polyacrylamide, ferrous sulfate, aluminum sulfate, and polyferric sulfate. Water purifiers have a strong purification effect, removing heavy metals from water. They are not affected by water temperature or pH, allowing for a wide range of applications. The treated water is highly transparent and can be reused.

[0049] Specifically, a cleaning box may be provided in the water storage device, and when the collected water needs to be processed, a water detergent may be placed in the cleaning box, or the water detergent may be placed in the cleaning box in advance before the water collection begins.

[0050] Configuring a water cleaner in the water storage can prevent the collected water in the water storage from producing excessive bacteria or other harmful substances, which may affect the storage effect and use effect of the collected water in the later stage.

[0051] In summary, the water circulation device provided in the embodiments of the present application is disposed within a drainage channel, beneath the drainage channel cover. It collects water through a water reservoir, connects multiple water reservoirs and enables the flow of collected water through a first connection port and a second connection port, and controls the discharge of collected water through a drain port and a drain plug, thereby recycling wastewater. This device can accommodate some excess rainwater, reduce the large amount of water discharged during heavy rain, and thus reduce the likelihood of flooding.

[0052] Another embodiment of the present application further provides a water circulation system. Please refer to Figures 2 and 3. The water circulation system includes a drainage channel 30, a drainage channel cover 20 and a plurality of water circulation devices 10 as described above.

[0053] The drain channel 30 is a pipe and ditch used for drainage, where water can be collected and discharged. Because water flowing into the drain channel is prone to carrying sediment, the drain channel is prone to clogging. Furthermore, when the water flow is too high, untimely drainage of the drain channel can lead to water accumulation or even flooding. Therefore, in this embodiment of the present application, a drain channel cover 20 is installed on the drain channel 30 to filter water, and a water circulation device 10 is installed within the drain channel 30 to store water and reduce drainage pressure.

[0054] The drain channel cover 20 is a device used to cover the drain channel 30 and filter the water flowing into the drain channel 30. The drain channel cover 20 is set on the drain channel 30 and matches the width of the drain channel 30. The water flowing into the drain channel 30 will first pass through the drain channel cover 20 for filtering, reducing impurities such as mud and debris from entering the water circulation device 10 and the drain channel 30, reducing the occurrence of blockage in the water circulation device 10 and the drain channel 30, and improving the availability of collected water.

[0055] In some embodiments, the drain channel cover is a detachable structure that can be removed relative to the drain channel, making it convenient to maintain the drain channel. Moreover, by simply removing the corresponding drain channel cover, the drain cover in the water circulation device can be easily removed, thereby easily draining the collected water.

[0056] In some embodiments, the drain cover comprises a plate body formed from multiple layers of hydrophobic filler layers, each layer having numerous gaps that form a drainage channel. As water flows through the drain cover, it flows through the gaps in the hydrophobic filler layers into the drain channel or water circulation system, leaving impurities such as fallen leaves and sand in the hydrophobic filler layers, thus achieving the unique filtration function of the hydrophobic filler layers.

[0057] In some embodiments, a drainage groove is provided at the bottom of the plate body of the drainage channel cover, and a drainage channel is formed by the drainage groove and the drainage channel to divert rainwater from the road surface.

[0058] The water circulation device 10 is used to collect water filtered by the drain channel cover 20. The water circulation device 10 is arranged in the drain channel 30, set up under the drain channel cover 20, and connected to the drain channel cover 20 to collect water filtered by the drain channel cover 20 and store the collected water in the water storage tank 11. The first side wall and the second side wall of the water storage tank 11 are respectively provided with a first connecting port 12 and a second connecting port 13. By connecting a connecting pipe 40 to the connecting port, multiple water circulation devices are connected together so that the collected water can circulate between the multiple water circulation devices, so that the collected water can be used in a centralized manner; a drain port 14 is provided on the bottom wall of the water storage tank 10, and a drain plug used in conjunction with the drain port. When water needs to be stored, the drain plug is used to close the drain port. When the collected water in the water storage tank needs to be discharged, the drain plug that closes the drain port is removed to allow the collected water to flow out smoothly.

[0059] Furthermore, the shape of the water reservoir 10 is adapted to the shape of the drain channel cover 20 and the available space of the drain channel 30 , and the shape of the water reservoir can be customized according to the use environment of the water reservoir.

[0060] When the water circulation device is used in different drains and / or with different drain covers, a suitable water reservoir can be customized accordingly so that the water reservoir can meet the usage requirements.

[0061] In some embodiments, two adjacent water storages 10 are spaced apart by the width of a drain cover 20 for ease of use.

[0062] Furthermore, the water reservoir may be made of any durable material, such as stainless steel, aluminum, plexiglass, polyvinyl chloride, and the like.

[0063] Furthermore, a water cleaner may be configured in the water reservoir to clean the collected water, improve the usability of the collected water, or meet specific recycling needs.

[0064] In some embodiments, the water circulation system further comprises a spray gun for cleaning using the collected water in the water reservoir.

[0065] The collected water can be used for a variety of purposes using a spray gun. For example, the collected water from the water reservoir can be used to clean drain covers, keeping them free of dust, mud, debris, and other debris, thereby maintaining their filtration function. When the collected water is used to flush the drain cover with the water reservoir below, the water reservoir can repeatedly collect the filtration water, and the collected water can be recycled. For example, the collected water from the water reservoir can be used to clean sidewalks or streets using a spray gun. For example, the collected water can be used to water urban greenery.

[0066] In summary, the water circulation system provided in the embodiments of the present application includes a drain channel, a drain channel cover, and multiple water circulation devices, each of which is connected by a connecting pipe. The drain channel cover can cover the drain channel and filter the water flowing into the drain channel. The water circulation device then collects the water filtered by the drain channel cover, thereby filtering and recycling rainwater, achieving water circulation. It can also accommodate some excess rainwater, reducing the large amount of water discharged by heavy rain, thereby reducing the probability of flooding. This is conducive to the construction of sponge cities and improving the city's adaptability to environmental changes and natural disasters caused by rainwater.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
