For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] One aspect of the present application provides a watering system for a sky garden.

[0037] Figure 1 This is a schematic diagram of the structure of the watering system of the sky garden according to some embodiments of the present application.

[0038] Reference Figure 1 As shown, the watering system of the sky garden greatly improves the survival rate of vegetation by cooperating with a multi-level stepped platform.

[0039] Reference Figure 1-2 A watering system for a sky garden is shown. As shown in the figure, a multi-level stepped platform 1 includes a first platform 10 and a second platform 20 from bottom to top. The first platform 10 is provided with a plurality of first flower beds 11, and the second platform 20 is provided with a plurality of second flower beds 21.

[0040] In some embodiments, the first flower bed 11 is disposed on the wall of the first platform 10 , so that the wall of the first platform 10 forms a landscape wall for viewing convenience.

[0041] In some embodiments, the first flower bed 11 is disposed on the ground of the first platform 10, which is convenient for viewing and can also provide a place for rest.

[0042] A connecting pipe 13 penetrating through the second platform 20 is provided at the bottom of the second flower bed 21 , and the connecting pipe 13 connects the first flower bed 11 and the second flower bed 21 .

[0043] In some embodiments, a protective cover 131 and a filter layer 132 are provided on the top of the connecting pipe 13. The filter layer 132 includes a first filter layer 132 of non-woven fabric and a second filter layer 132 of volcanic rock. The setting of the filter layer 132 ensures that the water flowing from the second flower bed 21 into the first flower bed 11 will not contain a large amount of impurities, or will not carry away the soil in the second flower bed 21, resulting in less nutrient soil in the second flower bed 21. Of course, it should be noted that the setting of non-woven fabric and volcanic rock is not unique. In other embodiments, it only needs to meet the same functional requirements in this implementation.

[0044] In some embodiments, the connecting pipe 13 is directly a through hole opened in the second platform 20, and the area around the through hole is paved with waterproof material. At the same time, a filter net with mesh sizes from small to large is arranged on the top of the through hole from bottom to top until the sand and gravel in the flower bed are filtered.

[0045] The bottom of each second flower bed 21 is connected by a circulation slot 12. The interconnection of the circulation slots 12 can enhance the circulation of several second flower beds 21 and improve the survival rate. It should be noted that the circulation slots are located underground and do not occupy the platform area in places other than the flower beds. Figure 3 As shown, the bottom of each second flower bed 21 is connected, and there is no special regulation for the connecting path placed in the circulation groove, which only needs to meet the straight-line distance. The circulation groove 12 is used to transfer excess water or nutrient solution in the adjacent second flower beds 21, so as to save resources and improve the survival rate of vegetation. Because the amount of soil required for the growth of high-altitude vegetation is less than that on the ground, nutrient solution must be continuously added. However, due to a series of problems such as pipelines and sunlight, the supply liquid in each second flower bed 21 is insufficient, which results in a low survival rate of green plants in individual second flower beds 21.

[0046] In some embodiments, in order to further ensure that the microorganisms in the second flower bed 21 will not be lost along with the circulation groove 12 or the connecting pipe 13, a plurality of small grooves 14 with openings facing upward are provided on the inner wall of the second flower bed 21. A certain amount of water is stored in the small grooves 14 for supplying the green plants in this flower bed. At the same time, the setting of the small grooves 14 also utilizes the growth of microorganisms.

[0047] In some embodiments, because the amount of soil in the second flower bed 21 is limited, when the outside rain is heavy, the rain cannot be allowed to wash the soil in the second flower bed 21, and the nutrients, microorganisms and minerals in the soil can not be allowed to flow away through the connecting pipes or flow grooves; at the same time, due to environmental problems, some places have local acid rain, and ground plants usually use a large amount of soil to neutralize the acid rain; but for high-altitude trees, such as the second flower bed 21 on the second platform in the present application, there is not enough soil to neutralize the impact of acid rain, so in some embodiments, in order to avoid the above-mentioned impacts on high-altitude trees, such as Figure 9-10 As shown, a rainproof device 15 is provided on the top of the second flower bed 21. The rainproof device 15 includes an arc-shaped hollow plate 151 and a rainproof film 152 arranged inside the arc-shaped hollow plate 151. The specific material size of the rainproof film 152 is not limited, and it only needs to be able to surround the trees to be protected; the rainproof film 152 can be pulled out from one end of the arc-shaped hollow plate 151, that is, when the rainproof device 15 is not in use, the rainproof film 152 is stored in the arc-shaped hollow plate 151. When it is needed, the rainproof film 152 is pulled out of the arc-shaped hollow plate 151. Of course, the size and volume of the arc-shaped hollow plate 151 are not specifically limited, and it only needs to fit the trees to be protected, ensuring that when the rainproof film 152 is pulled out of the arc-shaped hollow plate 151, the rainproof film 152 and the arc-shaped hollow plate 151 can effectively fit the trees to be protected. The other end of the arc hollow plate 151 is provided with a positive magnetic pole; the rainproof film 152 is evenly provided with support rods 153, and the size and shape of the support rods 153 are not limited, such as Fig.10 As shown, in some embodiments, the support rod 153 is a long straight rod and is vertically arranged; the number of the support rods 153 is not less than 2; one end of the support rod 153 is provided with a negative magnetic pole to match the positive magnetic pole on the arc-shaped hollow plate 151, connecting the pulled out rainproof film 152 and the arc-shaped hollow plate 151, so as to achieve the purpose of rainproof; the top of the second flower bed 21 is provided with an annular limiting groove 155, as shown in FIG. Fig.10As shown, the diameter of the annular limiting groove 155 is greater than 1.5 times the diameter of the foundation pit of the second flower bed 21, one end of the support rod slides along the annular limiting groove 155, and an elastic band 154 is provided at one end of the rainproof film 152 away from the annular limiting groove 155, and the support rod is used to support the rainproof film 152 The rainproof film 152 is fixed to prevent it from being washed away by rain. On the other hand, the elastic band 154 ensures that the top of the rainproof film 152 pulled out from the arc-shaped hollow plate 151 can effectively clamp the tree to be protected. At the same time, the setting of the limit groove can form an effective slope, which is convenient for isolating rainwater and prevents the trees from being impacted by rainwater all the time. Of course, for better adaptability, the movable end of the elastic band 154 is provided with a hook or other connection method to connect to the arc-shaped hollow plate 151. At this time, the vertical length of the support rod 153 is smaller than the vertical length of the rainproof film 152. Since the rainproof film 152 is made of flexible material, the elastic band 154 and the rainproof film 152 of the support rod 153 have a certain adaptability to fit the tree to be protected.

[0048] like Figure 1 As shown, the irrigation system of the sky garden includes: a waterscape device 100, a water reservoir 200, a return water pool 300, a first filter device 400, a second filter device 500 and an irrigation pipeline 600; the waterscape device 100 is used to construct a variety of waterscapes.

[0049] In some embodiments, the waterscape device 100 is, but is not limited to, an artificial lake, a pool, a pond, a stream, a water slope, a waterway, a waterfall, a water curtain, a cascade, a water wall or a fountain.

[0050] The water reservoir 200 includes a main pool 210 and a sub-pool 220; the main pool 210 and the sub-pool 220 are connected by a valve, the main pool 210 is used for daily collection and water supply, and the sub-pool 220 is used for configuring drip irrigation water. When the sub-pool 220 needs water, it can supply water by opening the valve. Of course, in order to configure the drip irrigation water, the sub-pool 220 is also connected to a nutrient solution pipeline. In order to increase the efficiency of drip irrigation and avoid the shutdown of the entire drip irrigation pipeline 230 due to damage to a single pipeline, a first filter 231 and a second filter 232 are provided between the drip irrigation pipeline 230 and the sub-pool 220. A water pump is connected to the end of the first filter 231 to provide a power source for drip irrigation management. Similarly, the end of the second filter 232 is also set like the first filter 231. When the pipeline connected to the first filter fails, the pipeline connected to the second filter 232 continues to work to transport the drip irrigation liquid to the drip irrigation nozzles 751 of each route. The waterscape device 100 is used to construct a variety of waterscape landscapes. In this embodiment, the waterscape device 100 is a waterfall and a fountain. The main pool 210 is used to collect and provide water for the waterfall and the fountain. Specifically, the water pumps of the waterfall and the fountain are separately arranged in the main pool 210. The two do not interfere with each other's working state, and the outdoor exposure of the waterfall and the fountain is used to dry the bleaching powder and chemical components contained in the tap water in the reservoir 200 to improve the water quality; the return water pool 300 is used to collect supplementary water. In this embodiment, the supplementary water includes one or more combinations of tap water, rainwater and residual water for irrigation, and water resources are reused; the input end of the first filtering device 400 is connected to the reservoir 200, and the output end of the first filtering device 400 is connected to the reservoir 200 and the return water pool 300.

The water in the water reservoir 200 is managed to prevent the waterfall or fountain from carrying sand or other debris into the water reservoir 200 and affecting the water utilization in the subsequent system. The specific first filter device 400 adopts multiple parallel filter sand cylinders. Of course, it should be noted that common filter equipment can also be used; the input end of the second filter device 500 is connected to the return water tank 300, and the output end of the second filter device 500 is connected to the water reservoir 200. The second filter device 500 is used to purify the reused water in the return water tank 300. The specific first filter device 400 adopts multiple parallel filter sand cylinders. Of course, it should be noted that common filter equipment can also be used; the irrigation pipeline 600 is connected to the water reservoir 200 and is used to irrigate green plants. In this embodiment, the green plants are irrigated mainly by sprinkler irrigation and drip irrigation.

[0051] When using sprinkler irrigation, such as: a general lawn with a rotary sprinkler head 751, in order to reduce the floor space and expand the spraying area, a sprinkler street lamp 700 is used to sprinkle green plants. The sprinkler street lamp 700 can also be used to sprinkle high vegetation, such as trees; specifically: Figure 6As shown, the spray street lamp 700 includes a base 710, on which a cavity lamp pole 720 is vertically fixed, a lampshade 730 is fixed on the top of the cavity lamp pole 720, a spray device 750 is inserted into the cavity lamp pole 720, and the spray device 750 includes a retractable water pipe, which is fixed to a support rod 740 through a fixing member, and the support rod 740 is placed inside the cavity lamp pole 720. A nozzle 751 is fixed at the top of the water pipe, and a joint is fixed at the bottom of the water pipe. The nozzle 751 is placed on the upper part of the cavity lamp pole 720, and the spray device 750 is cleverly combined with the street lamp to reduce the footprint and expand the spraying area.

[0052] When drip irrigation is used, general drip irrigation methods can be used, such as common drip tubes and drip arrows;

[0053] In some embodiments, in order to be suitable for drip irrigation of the sky garden, a steel pipe tree pool 800 with a drip irrigation function is used to achieve the drip irrigation effect, such as Figure 7-8 As shown, the steel pipe tree pool 800 includes a steel structure pool body 810, a stainless steel clamp 820 and an annular drip irrigation pipe 830; the steel structure pool body 810 is used to load green plants, and the specific green plants are large green plants such as trees.
