Description
Technical Field
[0001] The utility model relates to the technical field of rainwater collection and utilization, in particular to a park rainwater recycling system. Background Art
[0002] Planting flowers and plants in cities and parks not only beautifies the environment, but also improves the aesthetics of cities and parks. However, the existing urban green belts and park greening are not convenient for collecting rainwater, which does not meet the current requirements of energy conservation, environmental protection and rainwater recycling. As the saying goes, "all things grow from the soil", and water is one of the basic conditions for plant growth and an important factor in soil fertility. The amount of water directly affects the growth and development of plants. Unless an automatic irrigation system is laid, it is not convenient for staff to water the flowers and plants planted in the green belts quickly and labor-savingly, and they can only use long pipes to water the flowers and plants.
[0003] In order to make the environment more beautiful and interesting, and to create a natural atmosphere with flowers, trees, mountains and flowing water, a large number of rockery and waterfalls will be set up in the park. The combination of rockery and waterfall water increases the beauty. Water pipes and circulating water will be connected to the rockery to build a small waterfall, but most of the water used to make waterfalls is connected to the municipal water pipes, and the municipal water source is used to achieve viewing water flow. At the same time, once it rains, the naturally falling rainwater, including the rainwater in the rockery landscape area, is discharged through the municipal drainage network. The rainwater cannot be collected and recycled, resulting in a waste of water resources. Summary of the invention

[0039] like Figure 5As shown, in this embodiment, the two ends of the hollow brick 20 are respectively provided with a connecting portion 2001 and a connecting groove 2002, and the connecting portion 2001 and the connecting groove 2002 are plugged together. The upper half of the hollow brick 20 is a brick structure that can penetrate rainwater, while the lower half of the hollow brick 20 is a brick structure that cannot penetrate rainwater. It should be noted that the permeable floor brick 21 mentioned in this specification is a mature technology in the prior art, which can quickly penetrate rainwater. Its specific structure and permeability principle are not explained in detail here. The upper half of the hollow brick 20 adopts the same material structure as the permeable floor brick 21, and the lower half adopts the common impermeable floor brick structure. The two are combined together by gluing or applying cement at the joint (gluing can be epoxy glue or polyurethane glue). Such arrangement allows rainwater to enter the interior of the hollow brick 20 through the permeable floor brick 21 and the upper half of the hollow brick 20. Since the lower half of the hollow brick 20 cannot penetrate rainwater, the hollow brick 20 plays the role of collecting and transporting rainwater, transporting the rainwater to the second water pipe 9, and then the second water pipe 9 stores the rainwater in the water collecting tank 2.
[0040] In this embodiment, a second water pump 8 is provided in the rockery shell 1, and the output end of the second water pump 8 is connected to the fourth water pipe 11, and the end of the fourth water pipe 11 is connected to one side of the third collecting chamber 15, and a fifth water pipe 22 is provided on the side of the third collecting chamber 15 away from the fourth water pipe 11, and the end of the fifth water pipe 22 extends into the pool of the park.

[0042] After reaching the first collecting chamber 16 , the rainwater passes through the first porous plate 12 and enters the installation chamber 17 , where it is filtered by the filter assembly 13 . The filtered rainwater passes through the installation chamber 17 and drips into the second collecting chamber 18 and the third collecting chamber 15 , while the powdery substances in the rainwater that are not filtered by the filter assembly 13 are precipitated in the third collecting chamber 15 .
[0043] When it is necessary to spray rainwater to form a landscape waterfall, the first water pump 7 is started, and the first water pump 7 pumps out the rainwater in the third collection chamber 15 through the third water pipe 10, and transports the rainwater to the top of the rockery shell 1 through the first water pipe 5 and sprays the rainwater to form a landscape waterfall. The rainwater sprayed on the ground can be collected by the permeable floor tiles 21 and the hollow bricks 20. In this way, the landscape waterfall can be formed without the need for the rockery to be connected to the municipal pipeline, which greatly saves water resources.
[0044] After the device has been used for a period of time, a large amount of dust will accumulate in the third collection chamber 15. The input end of the second water pump 8 is connected to the external water pipe, the second water pump 8 is started, and the second water pump 8 is used to fill the third collection chamber 15 with high-pressure water through the fourth water pipe 11. At the same time, the valve on the fifth water pipe 22 is opened, and the dust in the third collection chamber 15 is flushed out by the fifth water pipe 22. This keeps the pipeline clean and avoids blockage that affects use.
[0045] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
