[0002] The vegetation in sunken gardens absorbs carbon dioxide and releases oxygen from the air, helping to purify the air and reduce air pollution. Greenery also reduces dust and noise pollution, improving the living environment for residents. Rainwater is one of the most precious freshwater resources in nature. By recycling rainwater from rooftop gardens, a significant amount of freshwater can be saved, meeting the daily water needs of the plants.

[0003] CN119122208A discloses a rainwater recycling and timely water-saving device for roof gardens, including a cultivation trough. The bottom of the cultivation trough is equipped with a filter assembly for filtering rainwater. A rainwater collection assembly is connected below the cultivation trough for collecting rainwater. A water storage assembly for storing rainwater and replenishing domestic water is connected to one side of the cultivation trough. A pump assembly is also provided on one side of the cultivation trough to connect the rainwater collection assembly and the water storage assembly. The invention is characterized by: a water-absorbing assembly for timely water absorption by plant roots inside the cultivation trough; a soil substrate is laid inside the cultivation trough; the water-absorbing assembly includes PVC pipes and a sponge; the sponge is evenly distributed within the soil substrate; one end of the sponge extends into a perforated PVC pipe assembly. This invention achieves rainwater recycling through the sponge, pipes, water storage tank, rainwater collection tank, and pump, and utilizes the collected rainwater for water-saving irrigation, watering only when plants are short of water, thus improving the efficiency of rainwater utilization.

[0004] However, the above-mentioned solutions cannot filter impurities in the rainwater during rainwater collection, which will cause impurities to enter the rainwater collection tank and cause blockage, making them impractical. Therefore, we provide a sunken garden for rainwater collection. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a sunken garden for rainwater harvesting, solving the technical problem that the inability to filter impurities in rainwater during rainwater harvesting leads to impurities entering the rainwater collection tank and causing blockage.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A rainwater harvesting sunken garden includes a mounting frame, a cultivation trough fixedly mounted on the top of the mounting frame, a nutrient layer for planting plants laid inside the cultivation trough, a drainage channel provided on one side of the cultivation trough, a filter box connected through the drainage channel on one side, a cover plate provided on the top of the filter box, a filtration mechanism provided inside the filter box, a drain pipe installed at the bottom of the filter box, a water storage tank fixedly mounted at the bottom end of the drain pipe, and a pumping assembly provided on one side of the water storage tank.

[0014] (III) Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a filtration mechanism, facilitates the cleaning of the filter plate. First, the pull rod is pulled upward, causing the locking block to move upward. Under the constraint of the sliding groove and the slider, the locking block slides upward stably until the entire locking block is above the filter plate. At this point, the positioning rod is no longer restricted, and it can be pulled to one side until one end of the positioning rod disengages from the positioning hole. At this point, the filter plate falls off the rectangular column, allowing for deep cleaning of the filter plate. During this process, the connecting plate compresses the restoring spring. Similarly, under the restoring force of the restoring spring, the positioning rod can enter the positioning hole, thus fixing the filter plate. At the same time, the locking block slides downward along the direction of the sliding groove under the action of gravity until it slides into the bottom of the positioning rod, thus restricting the position of the positioning rod and enhancing the fixing effect of the positioning rod.

[0015] 2. By setting up a water pumping component, the water pump can draw water from the water storage tank into a temporary water tank through a water pipe during the dry season. The pumped water slowly seeps into the cultivation tank through the through hole, which can replenish the water of the plants in the cultivation tank. Attached Figure Description

[0018] This application embodiment provides a sunken garden for rainwater harvesting. To facilitate cleaning of the filter plate, the pull rod is first pulled upwards, causing the locking block to move upwards. The locking block slides stably upwards under the constraint of the slide groove and the slider until the entire locking block is above the filter plate. At this point, the positioning rod is no longer restricted, and it can be pulled to one side until one end of the positioning rod disengages from the positioning hole. At this point, the filter plate falls off the rectangular column, allowing for deep cleaning of the filter plate. During this process, the connecting plate compresses the restoring spring. Similarly, under the restoring force of the restoring spring, the positioning rod can enter the positioning hole, thus fixing the filter plate. At the same time, the locking block slides downwards along the direction of the slide groove under the action of gravity until it slides into the bottom of the positioning rod, thus restricting the position of the positioning rod and enhancing the fixing effect of the positioning rod.

[0019] The technical solution in this application embodiment effectively solves the problem that the inability to filter impurities in rainwater during rainwater collection leads to impurities entering the rainwater collection tank and causing blockage. The overall approach is as follows: like Figures 1 to 5 To address the problems existing in the prior art, this utility model provides a sunken garden for rainwater harvesting, including a mounting frame 11. A cultivation trough 12 is fixedly installed on the top of the mounting frame 11. The inside of the cultivation trough 12 is lined with a nutrient layer 13 for planting plants. A drainage channel 14 is provided on one side of the cultivation trough 12. A filter box 15 is connected through the drainage channel 14 on one side. A cover plate 16 is provided on the top of the filter box 15. A filter mechanism 3 is provided inside the filter box 15. A drainage pipe 17 is installed at the bottom of the filter box 15. A water storage tank 18 is fixedly installed at the bottom end of the drainage pipe 17. A water pumping component 2 is provided on one side of the water storage tank 18. The drainage channel 14 is located below the nutrient layer 13. The drainage channel 14, the cultivation trough 12 and the filter box 15 are connected through the drainage channel 14 and the top side of the filter box 15.

[0020] Specifically, the filter mechanism 3 includes a rectangular post 31 installed at the bottom of the cover plate 16. A filter plate 32 is provided on the outside of the rectangular post 31. Multiple positioning holes 33 are provided on the surface of the rectangular post 31. A fixing component 34 connected to the rectangular post 31 is provided on the surface of the filter plate 32. The fixing component 34 includes a positioning rod 341 inserted into the upper surface of the filter plate 32. A connecting plate 342 is fixedly connected to the bottom of the positioning rod 341. A restoring spring 343 is fixedly connected between the connecting plate 342 and the filter plate 32. A locking block 344 is provided on one side of the positioning rod 341. A slider 346 is fixedly connected to one side of the locking block 344. A groove 345 corresponding to the slider 346 is provided on one side of the positioning rod 341. A pull rod 347 is fixedly connected to the top of the locking block 344.

[0021] By adopting the above technical solution, when the rainy season arrives, the cultivation tank 12 will be filled with rainwater. To prevent the plant roots inside the cultivation tank 12 from being soaked, the rainwater enters the drainage channel 14 through the nutrient layer 13 and then enters the filter box 15. After being filtered by the filter plate 32, it enters the water storage tank 18 through the drain pipe 17 and is stored. At the same time, the impurities in the rainwater and inside the nutrient layer 13 are located above the filter plate 32. By opening the cover plate 16, the impurities on the surface of the filter plate 32 can be cleaned. To facilitate cleaning the filter plate 32, first pull the lever 347 upward. The lever 347 drives the locking block 344 to move upward. The locking block 344 slides stably upward under the restriction of the sliding groove 345 and the slider 346 until the entire locking block 344 is in the correct position. When the filter plate 32 is above, the positioning rod 341 is no longer restricted and can be pulled to one side until one end of the positioning rod 341 is disengaged from the positioning hole 33. At this time, the filter plate 32 falls off the rectangular column 31, and the filter plate 32 can be deeply cleaned. During this process, the connecting plate 342 compresses the restoring spring 343. Similarly, under the action of the restoring force of the restoring spring 343, the positioning rod 341 can enter the positioning hole 33, which can fix the filter plate 32. At the same time, the locking block 344 will slide down along the direction of the slide groove 345 under the action of gravity until the locking block 344 slides into the bottom of the positioning rod 341, which can restrict the position of the positioning rod 341, thereby enhancing the fixing effect of the positioning rod 341.

[0022] Specifically, the water pumping assembly 2 includes a water pump 21 installed on the bottom side of the water storage tank 18. The output end of the water pump 21 is fixedly connected to a water pipe 22. The top side of the water pipe 22 is fixedly connected to a temporary water tank 23. The temporary water tank 23 is fixedly connected to the culture tank 12. A through hole 24 is opened between the bottom side of the temporary water tank 23 and the culture tank 12.

[0023] By adopting the above technical solution, in the event of a drought, the water pump 21 can pump the water inside the water storage tank 18 into the temporary water tank 23 through the water pipe 22. The pumped water slowly seeps into the cultivation tank 12 through the through hole 24, which can replenish the water for the plants inside the cultivation tank 12.

[0024] Working Principle: During use, when the rainy season arrives, the cultivation tank 12 will be filled with rainwater. To prevent the plant roots inside the cultivation tank 12 from being soaked, the rainwater enters the drainage channel 14 through the nutrient layer 13 and then enters the filter box 15. After being filtered by the filter plate 32, it enters the water storage tank 18 through the drain pipe 17 and is stored. At the same time, the impurities in the rainwater and inside the nutrient layer 13 are located above the filter plate 32. Opening the cover plate 16 allows for cleaning of the impurities on the surface of the filter plate 32. To facilitate cleaning the filter plate 32, first pull the lever 347 upwards. The lever 347 drives the locking block 344 upwards. The locking block 344 slides stably upwards under the constraint of the sliding groove 345 and the slider 346 until the locking block 344 is completely above the filter plate 32. At this point, the positioning rod 341 is no longer restricted, and the positioning rod 341 can be pulled to one side until the positioning rod... When one end of 341 is disengaged from the positioning hole 33, the filter plate 32 falls off the rectangular post 31, allowing for deep cleaning of the filter plate 32. During this process, the connecting plate 342 compresses the restoring spring 343. Similarly, under the restoring force of the restoring spring 343, the positioning rod 341 can enter the positioning hole 33, thus fixing the filter plate 32. At the same time, the locking block 344 will slide downward along the direction of the slide groove 345 under the action of gravity until the locking block 344 slides into the bottom of the positioning rod 341, thus restricting the position of the positioning rod 341 and enhancing the fixing effect of the positioning rod 341. In the event of a dry season, the water pump 21 can pump water from the water storage tank 18 into the temporary water tank 23 through the water pipe 22. The pumped water slowly seeps into the cultivation tank 12 through the through hole 24, replenishing the plants in the cultivation tank 12 with water.

[0025] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
