Description

Technical Field

[0001] This utility model belongs to the field of rainwater harvesting technology and relates to a purification and irrigation device, particularly a buried rainwater harvesting, purification, and irrigation device that is easy to maintain with a filter box. Background Technology

[0002] Water scarcity has become a global challenge, particularly in regions where agricultural production heavily relies on irrigation. The irrational use of water resources has led to a series of problems, including groundwater over-extraction and ecological degradation. As a major agricultural country, China has introduced numerous measures to promote the transformation and upgrading of agricultural water use methods through technological upgrades and policy guidance in the field of water-saving irrigation. Policy initiatives have provided opportunities for innovation in water-saving technologies, while technological advancements have provided practical and feasible solutions for policy implementation.

[0003] Traditional rainwater harvesting technologies suffer from several pollution issues: Suspended solids pollution: Frequent dust storms in the Hexi Corridor result in rainwater turbidity generally exceeding 50 NTU (standard limit ≤10 NTU). Microbial contamination: Untreated rainwater exhibits an average E. coli concentration of 200 CFU / 100 mL (irrigation water standard ≤100 CFU / 100 mL), increasing the risk of crop root rot by 30% (data source: "Research on the Correlation between Agricultural Irrigation Water Quality and Crop Diseases"). Agricultural non-point source pollution: Rainwater carries pesticide (e.g., organophosphates) and fertilizer (nitrate) residues after washing over farmland, leading to soil compaction and excessive nitrate levels in groundwater (2-3 times the limit in some areas). Therefore, there is an urgent need for a rainwater harvesting and purification irrigation system that can efficiently collect rainwater while ensuring water quality, enabling efficient utilization of rainwater resources. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a buried rainwater collection, purification, and irrigation device with an easy-to-maintain filter box. The technical problem this utility model aims to solve is: how to improve the efficiency and quality of rainwater collection and increase the utilization rate of rainwater.

[0005] The objective of this utility model can be achieved through the following technical solutions: An underground rainwater collection, purification, and irrigation device with an easy-to-maintain filter box includes a clean water tank, a drain pipe installed on the clean water tank, an ultraviolet lamp installed inside the clean water tank, a water collection cover fixed to the clean water tank by a support rod, a drain pipe fixed to the upper end of the clean water tank, an overflow pipe fixed to the upper end of the drain pipe, a filter box fixed to the upper end of the overflow pipe, the upper end of the filter box being fixedly connected to the water collection cover, an inlet and outlet opening on the side of the filter box, a sealing plate installed on the inlet and outlet by bolts, three mesh frames connected to the sealing plate by connecting components, and a filter packing layer installed inside the mesh frames.

[0006] The working principle of this utility model is as follows: When in use, the water purification tank is buried underground, while the filter box and water collection cover are set above ground. The drain pipe of the water purification tank is connected to the irrigation pipe, which can be used to set up an irrigation network in a small area or to form a regional irrigation system. It is not restricted by the land area. This design can reduce the footprint. The filter box has an inlet and outlet on the side, which makes it easy to replace the internal filter media layer. Multiple filters can be replaced at the same time or individually to meet different maintenance needs. It is highly practical.

[0007] The three filter media layers, from top to bottom, are a waste gravel layer, a waste sand and gravel layer, and an activated carbon layer.

[0008] By adopting the above structure and utilizing discarded construction waste, costs can be reduced while effectively removing large particulate impurities from rainwater, with a removal rate of up to 90%.

[0009] An overflow port is provided on the side of the overflow pipe, and a sealing ring is slidably connected inside the overflow pipe. A connecting rod is fixed at the center of the sealing ring, and the other end of the connecting rod extends into the water tank and is fixed with an annular buoyancy seat.

[0010] With the above structure, during use, the sealing ring blocks the overflow port. When the water level in the clean water tank reaches a certain height, it drives the annular buoyancy seat to rise, which in turn drives the sealing ring to rise through the connecting rod, causing the sealing ring to disengage from the overflow port. This allows excess rainwater to drain out of the overflow port, preventing rainwater from backflowing into the filter box and water collection hood when the clean water tank is full. This also prevents dirt from being carried out of the filter box and reduces the pressure in the filter box and water collection hood, thus protecting the device.

[0011] The connecting assembly includes a connecting seat and a fixing plate. The connecting seat has an installation groove and a limiting cavity inside. The fixing plate is fixed to the right side of the mesh frame. A fixing rod is fixed to the fixing plate. The fixing rod extends into the limiting cavity. A limiting assembly is provided in the limiting cavity. A pressure rod is provided on the limiting assembly. The other end of the pressure rod extends out of the connecting seat.

[0012] With the above structure, initially, the fixing plate is located in the mounting groove, and the fixing rod is inserted into the limiting groove and fixed by the limiting component. When installing or disassembling the mesh frame, the limiting component can be released by the pressure rod to release the locking of the fixing rod, so that the fixing rod can be pulled out to complete the disassembly of the mesh frame, which is convenient for replacing the filter packing layer. The operation is simple and convenient.

[0013] The limiting component includes a limiting ring, a limiting notch is provided on the lower side of the fixed rod, a lifting plate is slidably connected in the limiting cavity, a limiting ring is fixed on the lower side of the lifting plate, the limiting ring is sleeved on the outer periphery of the fixed rod and corresponds to the limiting notch, the pressure rod is fixedly connected to the lifting plate, an avoidance groove is provided at the upper end of the limiting groove, a tension spring is fixed inside the avoidance groove, and the other end of the tension spring is fixedly connected to the lifting plate.

[0014] With the above structure, initially, under the tension of the tension spring, the limiting ring is locked in the limiting notch, thus limiting the fixed rod. During disassembly, the pressure rod drives the lifting plate to descend, thereby causing the limiting ring to disengage from the limiting notch, allowing the fixed rod to be pulled out.

[0015] The filter box has three support seats fixed on the left side inside, corresponding to the mesh frame. The lower side of the mesh frame is placed on the support seats, and a guide slope is opened on the right side of the support seats.

[0016] With the above structure, the support base can support the wire mesh frame and ensure its stability. The inclined surface can guide the wire mesh frame when it enters, preventing it from deforming under gravity and conflicting with the support base.

[0017] Compared with existing technologies, this buried rainwater harvesting, purification, and irrigation device, which is easy to maintain with its filter box, has the following advantages: 1. In use, the water purification tank is buried underground, while the filter box and water collection cover are set above ground. The drain pipe of the water purification tank is connected to the irrigation pipe, which can be used to set up a small-scale irrigation network or multiple units to form a regional irrigation system. It is not restricted by the land area. This design can reduce the footprint. The filter box has an inlet and outlet on the side, which makes it easy to replace the internal filter media layer. Multiple filters can be replaced at the same time or one filter can be replaced to meet different maintenance needs. It is highly practical.

[0018] 2. Utilizing discarded construction waste can reduce costs and effectively remove large particulate impurities from rainwater, with a removal rate of up to 90%.

[0019] 3. During use, the sealing ring blocks the overflow port. When the water level in the clean water tank reaches a certain height, it drives the annular buoyancy seat to rise, which in turn drives the sealing ring to rise through the connecting rod. This causes the sealing ring to disengage from the overflow port, allowing excess rainwater to drain out. This prevents rainwater from backflowing into the filter box and water collection hood when the clean water tank is full. On the one hand, it prevents dirt in the filter box from being carried out, and on the other hand, it reduces the pressure in the filter box and water collection hood, thus protecting the device.

[0020] 4. Initially, the fixing plate is located in the mounting groove, and the fixing rod is inserted into the limiting groove and fixed by the limiting component. When installing or disassembling the mesh frame, the limiting component can be released by the pressure rod to release the locking of the fixing rod, so that the fixing rod can be pulled out to complete the disassembly of the mesh frame, which is convenient for replacing the filter packing layer. The operation is simple and convenient. Attached Figure Description

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figures 1-4 As shown, this underground rainwater collection, purification, and irrigation device, which facilitates filter box maintenance, includes a clean water tank 1, a drain pipe 2 installed on the clean water tank 1, an ultraviolet lamp installed inside the clean water tank 1, a water collection cover 5 fixed to the clean water tank 1 by a support rod 4, a drain pipe 6 fixed to the upper end of the clean water tank 1, an overflow pipe 7 fixed to the upper end of the drain pipe 6, a filter box 3 fixed to the upper end of the overflow pipe 7, the upper end of the filter box 3 being fixedly connected to the water collection cover 5, an inlet and outlet 12 opened on the side of the filter box 3, a sealing plate 13 installed on the inlet and outlet 12 by bolts, three mesh frames 15 connected to the sealing plate 13 by connecting components, and a filter packing layer installed inside the mesh frames 15.

[0028] In use, the water purification tank 1 is buried underground, while the filter box 3 and the water collection cover 5 are set above ground. The drain pipe 2 of the water purification tank 1 is connected to the irrigation pipe, which can be used to set up a small-scale irrigation network or multiple units to form a regional irrigation system. It is not restricted by the land area. This design can reduce the footprint. The filter box 3 has an inlet and outlet 12 on its side, which makes it easy to replace the internal filter media layer. Multiple filters can be replaced at the same time or one filter can be replaced to meet different maintenance needs. It is highly practical.

[0029] The three filter media layers, from top to bottom, are a waste gravel layer, a waste sand and gravel layer, and an activated carbon layer.

[0030] By adopting the above structure and utilizing discarded construction waste, costs can be reduced while effectively removing large particulate impurities from rainwater, with a removal rate of up to 90%.

[0031] An overflow port 9 is provided on the side of the overflow pipe 7. A sealing ring 8 is slidably connected inside the overflow pipe 7. A connecting rod 11 is fixed at the center of the sealing ring 8. The other end of the connecting rod 11 extends into the water tank 1 and is fixed with an annular buoyancy seat 10.

[0032] With the above structure, during use, the sealing ring 8 seals the overflow port 9. When the water level in the clean water tank 1 reaches a certain height, it drives the annular buoyancy seat 10 to rise, which in turn drives the sealing ring 8 to rise through the connecting rod 11, causing the sealing ring 8 to disengage from the overflow port 9. This allows excess rainwater to be discharged from the overflow port 9, preventing rainwater from filling the filter box 3 and the water collection cover 5 and causing backflow when the clean water tank 1 is full. This prevents dirt in the filter box 3 from being carried out and reduces the pressure in the filter box 3 and the water collection cover 5, thus protecting the device.

[0033] The connecting assembly includes a connecting seat 14 and a fixing plate 17. The connecting seat 14 has an installation groove and a limiting cavity inside. The fixing plate 17 is fixed on the right side of the mesh frame 15. A fixing rod 18 is fixed on the fixing plate 17. The fixing rod 18 extends into the limiting cavity. A limiting component is provided in the limiting cavity. A pressure rod 22 is provided on the limiting component. The other end of the pressure rod 22 extends out of the connecting seat 14.

[0034] With the above structure, initially, the fixing plate 17 is located in the mounting groove, and the fixing rod 18 is inserted into the limiting groove and fixed by the limiting component. When installing or disassembling the mesh frame 15, the limiting component can be released from locking the fixing rod 18 by the pressure rod 22, so that the fixing rod 18 can be pulled out to complete the disassembly of the mesh frame 15, which is convenient for replacing the filter packing layer. The operation is simple and convenient.

[0035] The limiting assembly includes a limiting ring 20, a limiting notch 19 on the lower side of the fixing rod 18, a lifting plate 21 slidably connected inside the limiting cavity, a limiting ring 20 fixed on the lower side of the lifting plate 21, the limiting ring 20 being sleeved on the outer periphery of the fixing rod 18 and corresponding to the limiting notch 19, a pressure rod 22 being fixedly connected to the lifting plate 21, an avoidance groove 23 being provided at the upper end of the limiting groove, a tension spring 24 being fixed inside the avoidance groove 23, and the other end of the tension spring 24 being fixedly connected to the lifting plate 21.

[0036] With the above structure, initially, under the tension of the tension spring 24, the limiting ring 20 is locked in the limiting notch 19, thereby limiting the fixing rod 18. During disassembly, the pressure rod 22 drives the lifting plate 21 to descend, thereby causing the limiting ring 20 to disengage from the limiting notch 19, allowing the fixing rod 18 to be pulled out.

[0037] The filter box 3 has three support seats 16 fixed on the left side inside, corresponding to the mesh frame 15. The lower side of the mesh frame 15 is placed on the support seats 16, and a guide slope is provided on the right side of the support seats 16.

[0038] With the above structure, the support base 16 can support the mesh frame 15 and ensure the stability of the mesh frame 15. The inclined surface can guide the mesh frame 15 when it enters, preventing the mesh frame 15 from deforming under gravity and conflicting with the support base 16.

[0039] The working principle of this utility model is as follows: In use, the water purification tank 1 is buried underground, while the filter box 3 and water collection hood 5 are installed above ground. The drain pipe 2 of the water purification tank 1 is connected to an irrigation pipe, allowing for the deployment of a small-scale irrigation network or the formation of multiple regional irrigation systems, without being limited by land area. This design reduces the footprint. The filter box 3 has an inlet / outlet 12 on its side. Initially, the fixing plate 17 is located in the mounting groove, and the fixing rod 18 is inserted into the limiting groove. Under the tension of the tension spring 24, the limiting ring 20 is engaged. Within the limiting notch 19, the fixing rod 18 is limited. When installing or disassembling the mesh frame 15, the lifting plate 21 can be lowered by the pressure rod 22, thereby causing the limiting ring 20 to disengage from the limiting notch 19, releasing the locking of the fixing rod 18, and allowing the fixing rod 18 to be pulled out, thus completing the disassembly of the mesh frame 15. This facilitates the replacement of the filter media layer, making the operation simple and convenient. It is easy to replace the internal filter media layer, and multiple layers can be replaced simultaneously or individually to meet different maintenance needs, making it highly practical. During use, the sealing ring 8 seals the overflow port 9. When the water level in the clean water tank 1 reaches a certain height, it drives the annular buoyancy seat 10 to rise, which in turn drives the sealing ring 8 to rise through the connecting rod 11. This causes the sealing ring 8 to disengage from the overflow port 9, allowing excess rainwater to drain out of the overflow port 9. This prevents rainwater from backflowing into the filter box 3 and water collection cover 5 when the clean water tank 1 is full. On the one hand, it prevents dirt in the filter box 3 from being carried out, and on the other hand, it reduces the pressure in the filter box 3 and water collection cover 5, thus protecting the device.

[0040] In summary, the structure of filter box 3 and water purification box 1 improves the efficiency and quality of rainwater collection and enhances the utilization rate of rainwater.

[0041] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
