[0002] In reality, rainwater, as a clean and renewable water resource, can alleviate the water resource pressure of garden irrigation when collected and utilized in landscape gardens, and has significant economic value. However, there are many problems with the rainwater collection devices currently used in landscape gardens.

[0003] First, rainwater tends to carry a large amount of debris such as leaves, twigs, and soil particles when it falls. This debris easily adheres to the surface of the filter screen, making the cleaning process cumbersome and requiring the entire filter structure to be disassembled to remove the debris, which is time-consuming and laborious. Therefore, it is necessary to improve the existing rainwater harvesting device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rainwater harvesting device for landscape architecture, solving the problems mentioned in the background art.

[0012] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model will be clearly and completely described. Example

[0013] A rainwater harvesting device for landscape gardens includes an underground collection box 1 made of 304 stainless steel, with an overall cylindrical structure. The use of the rainwater collected in the collection box 1 is based on existing technology, such as installing a water pump inside and connecting external sprinklers, which will not be elaborated upon in this invention. The upper opening of the collection box 1 tapers inward to form an extension box 2, also made of 304 stainless steel. The extension box 2 extends above the ground, and several overflow ports 2-1 are provided on its wall near the ground. During heavy rain, when the rainwater in the collection box 1 reaches a set level, excess rainwater is discharged through the overflow ports 2-1. A filter screen 3, made of stainless steel wire mesh, is installed in the middle of the extension box 2. Made of 2mm mesh, the filter screen effectively intercepts large particles such as leaves and twigs carried by rainwater. A ring 4, matching the inner wall of the extension box 2, is fixed to the top of the filter screen 3. The ring 4 is secured to the extension box 2 by multiple horizontally placed bolts made of 304 stainless steel to ensure a strong and corrosion-resistant connection. The top center of the filter screen 3 is concave and hemispherical, allowing gravity and water flow to guide filtered debris to the center of the filter screen 3 for collection by the debris-collecting mechanism. A debris-collecting mechanism is located at the center of the filter screen 3, with a vertically oriented circular hole for accommodating it. A detachable lifting structure is installed at the top of the extension box 2, with its lower end connected to the debris-collecting mechanism. After rainwater falls above extension box 2, it flows naturally into extension box 1. First, it is filtered by filter screen 3. Large particles of debris such as leaves, twigs, and soil particles carried by the rainwater are intercepted by filter screen 3. Because filter screen 3 has a hemispherical concave structure, under the combined action of gravity and the impact of rainwater flow, the intercepted debris will gather along the inclined surface of filter screen 3 towards the central hole, avoiding the uniform accumulation of debris on the surface of filter screen 3 and causing the filter holes to become clogged. The filtered rainwater flows into collection box 1 through the filter holes of filter screen 3 for storage, realizing the initial collection of rainwater. Example

[0014] Based on the first embodiment, the debris collection mechanism includes a collection cylinder 5, which is made of stainless steel 304. The collection cylinder 5 is open at the top and closed at the bottom. Multiple water leakage holes 5-1 are provided on the cylinder wall of the collection cylinder 5 to ensure that rainwater entering the collection cylinder 5 can quickly seep out to the collection box 1, while intercepting debris and leaving it in the collection cylinder 5.

[0015] After rainwater flows into the extension box 2, it is filtered by the filter screen 3. Under the action of gravity and water flow, the debris gathers towards the center of the filter screen 3 and eventually falls into the collection cylinder 5. The rainwater entering the collection cylinder 5 seeps out quickly through the water leakage hole 5-1 on the cylinder wall and flows into the collection box 1 for storage, while the debris is intercepted inside the collection cylinder 5. The closed bottom of the collection cylinder 5 prevents debris from falling into the collection box 1. When the debris in the collection cylinder 5 accumulates to a certain amount, the collection cylinder 5 can be removed and cleaned by the subsequent matching lifting mechanism without disassembling the filter screen 3. Example

[0016] Based on the second embodiment, the lifting mechanism includes multiple load-bearing rods 6, which are fixed perpendicularly to each other in a grid pattern. Several openings 2-2 are provided on the top wall of the extension box 2. Both ends of each load-bearing rod 6 are placed in two opposite openings 2-2. Several steel wires 7 are fixed on the top wall of the collecting cylinder 5, and the upper ends of the steel wires 7 are fixed on the load-bearing rods 6.

[0017] The rainwater filtration and debris collection process is the same as in the second embodiment. When it is necessary to clean the debris in the collection tube 5, the staff does not need to use tools. They can directly lift the grid structure of the load-bearing rod 6 by hand. Since the two ends of the load-bearing rod 6 are placed in the notch 2-2, disassembly is convenient. When the load-bearing rod 6 is lifted, the collection tube 5 is moved upward synchronously through the steel wire 7. The collection tube 5 is taken out from the round hole of the filter screen 3. The staff can directly pour the debris in the collection tube 5 into the trash can. After cleaning, the collection tube 5 is put back into the round hole of the filter screen 3, and the two ends of the load-bearing rod 6 are put back into the notch 2-2 to complete the reset. In addition, in non-rainy weather, the grid-shaped load-bearing rod 6 can be used as a temporary rest platform. Tourists can sit on the load-bearing rod 6 to rest, and the grid structure will not affect the normal collection of rainwater. Example

[0018] Based on the third embodiment, in order to improve the practicality of the whole device, the load-bearing rod 6 is hollow and filled with mosquito repellent. The mosquito repellent is a mixture of natural mosquito repellent grass powder and artemisia extract. The filling amount is 80% of the internal volume of each load-bearing rod 6. A diffusion hole 6-1 is opened at the bottom of the connection of multiple load-bearing rods 6 to diffuse the mosquito repellent scent of the mosquito repellent in the load-bearing rod 6 to the surrounding environment to achieve the mosquito repellent effect.

[0019] The workflow for rainwater collection, filtration, debris collection, and cleaning is completely consistent with that of the third embodiment. During daily use, the mosquito repellent filling inside the load-bearing rod 6 will slowly evaporate. The evaporated mosquito repellent scent is released into the surrounding environment of the extension box 2 through the diffusion hole 6-1 at the bottom, forming a mosquito repellent area within a certain range. Since the device is set in the green area of ​​the landscape garden, the surrounding area is usually a place for tourists to rest and take walks. The mosquito repellent function can effectively reduce mosquito bites and improve the user experience of tourists. At the same time, the mosquito repellent uses natural plant extracts, which are environmentally friendly and pollution-free, and will not affect the ecological environment of the garden or the quality of the collected rainwater.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
