[0019] The rainwater harvesting device for gardens according to this utility model has the following advantages:

[0020] 1. This utility model discloses a rainwater collection device for gardens. By setting up pre-embedded parts and a rainwater filtration structure, a foundation pit is first dug on the side of the garden near the rainwater channel to pre-embed the shell. Then, the lifting frame is inserted into the pre-embedded shell and covered with a drain cover. When it rains, the rainwater in the garden will enter the lifting frame along the drain cover, and then pass through the interception component and the first filter component in sequence into the pump body cavity. Then, the water filtered in the pump body cavity is pumped into the return water cavity by the water pump, and the water seeps into the second filter component from the bottom of the second filter cavity to filter the water again. The filtered water can be stored after entering the clear water cavity. Therefore, there is no need to excessively excavate the ground in the garden, and the damage to objects in the garden is small, which has strong practicality.

[0021] 2. A garden rainwater collection device of this utility model is provided. By setting an overflow pipe, after the pre-embedded shell is buried in the foundation pit, the overflow pipe needs to be connected to the rainwater channel. When the rainwater is too heavy and the water pump cannot pump the water in the pump body cavity in time, the excess water can be discharged into the rainwater channel along the overflow pipe as the water level rises, so as to avoid rainwater surging and flooding the ground.

[0022] 3. A garden rainwater collection device of this utility model, by setting up a lifting frame, can be removed from the pre-embedded shell by pulling the lifting frame upward, thereby cleaning the first filter component and the second filter component. Attached Figure Description

[0034] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a rainwater harvesting device for gardens.

[0035] like Figures 1-4 As shown, this utility model discloses a rainwater collection device for gardens, comprising: embedded parts and a rainwater filtration structure.

[0036] The embedded components include an embedded housing 10, an overflow pipe 11 fixedly installed on the front of the embedded housing 10, a drain cover 12 snapped onto the upper surface of the embedded housing 10, and a drain pipe 13 fixedly installed on the lower surface of the embedded housing 10. Multiple foundation pits are dug at equal intervals on one side of the garden near the rainwater channel, and then multiple embedded housings 10 can be buried in multiple foundation pits. At this time, the overflow pipe 11 needs to be connected to the rainwater channel, and the drain pipe 13 is connected to the external pump set.

[0037] The rainwater filtration structure is installed on the inner wall of the pre-embedded housing 10. It includes a pull-up frame 20 that snaps into the inner wall of the pre-embedded housing 10. A hanging ear is provided on the outer side of the port of the pull-up frame 20, and the hanging ear abuts against the groove of the embedded opening of the pre-embedded housing 10 for support. An interception assembly is installed on the inner wall of the pull-up frame 20, comprising a first filter chamber 21, a second filter chamber 22, a clean water chamber 23, a pump body chamber 24, and a return water chamber 25, respectively, placed inside the pull-up frame 20. A first filter assembly and a second filter assembly are placed inside the first filter chamber 21 and the second filter chamber 22, respectively, and a water pump 26 is fixedly installed on the inner wall of the pump body chamber 24. In this embodiment, the interior of the pull-up frame 20 is separated by a partition plate, which juxtaposes the first filter chamber 21 with the second filter chamber 22, the return water chamber 25, the pump body chamber 24, and the clean water chamber 23 arranged longitudinally from top to bottom. An overflow gap is reserved between the top of the partition plate and the interception assembly. The inner bottom wall of the lifting frame 20 has a through hole, and a sealing joint 60 connected to the drain pipe 13 is fixedly installed on the inner wall of the through hole. After the pre-embedded shell 10 is buried in the foundation pit, the lifting frame 20 is inserted into the pre-embedded shell 10. At this time, the drain pipe 13 will enter the sealing joint 60. The sealing joint 60 allows the drain pipe 13 to communicate with the interior of the clear water chamber 23. At the same time, tightening the sealing joint 60 prevents water in the clear water chamber 23 from flowing out along the through hole. Then, the drain cover 12 is placed on the pre-embedded shell 10. At this time, the drain cover 12 is flush with the ground. Furthermore, in this embodiment, the overflow pipe 11 on the front of the pre-embedded shell 10 is connected to the clear water chamber 23 of the lifting frame 20, and the connection hole between the overflow pipe 11 and the lifting frame 20 is located on the upper side wall of the lifting frame 20.

[0038] The interception assembly includes a water guide plate 70, a support frame 71 fixedly mounted on the upper surface of the water guide plate 70, a filter screen plate 72 fixedly mounted on the upper surface of the support frame 71, and a water leakage groove 73 formed on the surface of the water guide plate 70. A baffle frame 74 is fixedly mounted on the inner wall of the lifting frame 20, and the baffle frame 74 is inclined. The interception assembly is placed at an angle in the lifting frame 20 via the baffle frame 74. The water leakage groove 73 is located at one end of the water guide plate 70 and at the lowest position of the interception assembly within the lifting frame 20. The water leakage groove 73 is directly above the first filter chamber 21. The baffle frame 74 supports the water guide plate 70, thus facilitating the disassembly and cleaning of the interception assembly.

[0039] When it rains, rainwater in the garden will enter the lifting frame 20 along the drain cover 12. The rainwater entering the lifting frame 20 will first pass through the inclined filter screen 72 to intercept large particles of impurities in the rainwater. The intercepted water will enter the inclined water guide plate 70, and then enter the first filter chamber 21 along the drain channel 73.

[0040] A flow channel 30 is provided between the first filter chamber 21 and the pump body chamber 24. The first filter assembly is composed of coarse pebbles 80, which are located below the first filter chamber 21, and the water leakage channel 73 is located above the first filter chamber 21. When rainwater enters the first filter chamber 21, the coarse pebbles 80 can perform preliminary filtration of small particles in the rainwater. The water after preliminary filtration will enter the pump body chamber 24 along the flow channel 30.

[0041] A water-turning trough 31 is provided between the second filter chamber 22 and the clear water chamber 23, and the return water chamber 25 is separated from the second filter chamber 22 by a mesh plate 50. The second filter assembly is composed of volcanic rock 81, fine sand 82 and activated carbon 83. In the second filter assembly, the volcanic rock 81, fine sand 82 and activated carbon 83 are laid in layers from bottom to top in the second filter chamber 22.

[0042] A water guide pipe 40 is fixedly installed at the outlet end of the water pump 26, and one end of the water guide pipe 40 extends into the interior of the return water chamber 25. Driving the water pump 26 can draw water from the pump body chamber 24 into the return water chamber 25. As the water pump 26 continuously pumps in rainwater, the rainwater will pass through the mesh plate 50 and enter the second filter chamber 22. Since the rainwater seeps into the second filter assembly from the bottom of the second filter chamber 22 and flows into the clear water chamber from the overflow trough, the pressurization of the water pump can accelerate the passage of the rainwater through the second filter assembly and filter the rainwater again. The filtered water can be stored after entering the clear water chamber 23. When the water in the clear water chamber 23 needs to be used, the external pump group can be driven to discharge the water in the clear water chamber 23 along the drain pipe 13, and the lifting frame 20 can be pulled up to remove the lifting frame 20 from the pre-embedded housing 10, so that the first filter assembly and the second filter assembly can be cleaned.

[0043] Compared with existing technologies, this device only requires digging a pit on one side of the rainwater channel to bury the pre-embedded shell 10, without excessive excavation of the ground in the garden, causing less damage to objects in the garden and having strong practicality.

[0044] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
