Description

Technical Field

[0001] The invention belongs to the technical field of rainwater recycling, and in particular relates to a garden rainwater recycling device. Background Art

[0002] A garden is a natural environment and recreational space created by applying engineering technology and artistic means within a specific area, through the transformation of terrain (or further construction of mountains, stone stacking, and water management), the planting of trees and flowers, the construction of buildings, and the layout of garden paths. Garden rainwater recycling is an environmentally friendly practice that utilizes rainwater resources. It can collect, store, and utilize rainwater to meet the irrigation needs of landscaping, reducing reliance on tap water. This helps conserve water resources and lower water bills. It can also reduce the pressure of rainwater runoff on urban drainage systems and reduce the risk of flooding. Currently, garden rainwater recycling devices are generally used to recycle rainwater. Through these facilities, rainwater can be collected and stored for reuse in landscaping.

[0003] Existing garden rainwater recycling devices typically use reservoirs or storage tanks around the garden to collect rainwater from the surrounding area during rainy days to meet water needs during other periods. For example, Chinese patent document CN214574535U discloses a rainwater recycling device for garden irrigation. To address the problem of inconvenient impurity removal in existing rainwater recycling devices, a solution is proposed, comprising a storage tank, a mounting frame, a water pump, and a PLC controller mounted on the mounting frame. The storage tank has an opening at the top, a filter screen is installed inside the storage tank, and the mounting frame is mounted above the storage tank. Two first electric telescopic rods are mounted on the top of the mounting frame, with their extended ends facing vertically downward. Each of the extended ends of the first electric telescopic rods is fixed to a mounting plate, which is located inside the storage tank. This device has a reasonable structure and is simple to operate. It not only filters impurities from rainwater, but also conveniently removes the filtered impurities from the filter screen, thereby facilitating the recycling and utilization of rainwater and making it easy to promote and use.

[0004] The water reservoirs or storage tanks in the existing technology are generally large and can accommodate a large amount of rainwater. However, large water reservoirs or storage tanks will occupy the green space of the garden. Although it is possible to solve the problem of large land area by digging a water reservoir underground in the garden and covering and planting plants on the top, this method is dangerous and will also affect the types of plants planted on the top, affecting the overall beauty of the garden landscape. There is a lack of corresponding supporting and complete structures. Therefore, it is necessary to reset the existing rainwater recovery overall structure to solve these problems.

The rainwater collecting mechanism 1 is arranged on the surrounding side of the garden building 6 to collect rainwater from the garden building 6, so that the garden rainwater recovery rate is greatly improved.

[0021] The rainwater conveying mechanism 2 is used to convey rainwater collected by the rainwater collection mechanism 1 to the rainwater filtering mechanism 3. Specifically, the rainwater conveying mechanism 2 includes a conveying hose, the ends of which are connected to the rainwater collection mechanism 1 and the rainwater filtering mechanism 3, respectively.
