[0032] An unpowered roof rainwater's layered water storage recycling system, such as Figures 1-3As shown, including the shell unit 1, vertical pipe unit 2, water storage unit 3; wherein the vertical pipe unit 2 extends from the roof to the bottom of the building, the shell unit 1 is arranged at the uppermost end of the vertical pipe unit 2, the water storage unit 3 is connected with the vertical pipe unit 2 to realize the water storage function; the vertical pipe unit 2 includes a main vertical pipe assembly 201, a secondary vertical pipe assembly 202, the main vertical pipe assembly 201 is arranged at the side of the secondary vertical pipe assembly 202 close to the water retaining wall 5, wherein the main vertical pipe assembly 201 extends from the roof to the bottom of the building, and the secondary vertical pipe assembly 202 extends from the roof to the bottom of the building while being provided with a transverse branch in communication with the water storage unit 3.

[0033] The application first opens the vertical pipe unit 2 at the top of the floor 4, the shell unit 1 is arranged above the vertical pipe unit 2, the water storage unit 3 is arranged at each floor, and the water storage unit 3 at each floor is connected with the vertical pipe unit 2, in addition, the vertical pipe unit 2 is further provided with the main vertical pipe assembly 201 and the secondary vertical pipe assembly 202, wherein the main vertical pipe assembly 201 extends vertically downward from the top of the floor 4 to the underground rainwater recovery system at the bottom of the building, the secondary vertical pipe assembly 202 extends vertically downward from the top of the floor to the bottom of the building and converges with the main vertical pipe assembly 201, and the secondary vertical pipe assembly 202 is further provided with a transversely extending cross branch 207 at each floor, which is connected with the water storage unit 3 at each floor, so as to realize the diversion of rainwater in the secondary vertical pipe assembly 202 to the water storage unit 3 at each floor.

[0034] The application can fully drain the roof rainwater into the water storage unit 3 by arranging the secondary vertical pipe assembly 202, realize efficient utilization of rainwater, in addition, the structural relationship and connection mode of the secondary vertical pipe assembly 202 and the water storage unit 3 in each floor of the application are consistent design (except for the top floor and the first floor), wherein the difference lies in that the top end of the top floor secondary vertical pipe assembly 202 is provided with the shell unit 1, and the bottom end of the first floor secondary vertical pipe assembly 202 converges into the main vertical pipe assembly 201. Meanwhile, the roof connected with the water retaining wall 5 has a certain inclination, wherein the height of the top end of the floor close to the water retaining wall 5 is lower than the height of the top end of the floor away from the water retaining wall 5. The application can not only collect rainwater by arranging the main vertical pipe assembly 201 and the secondary vertical pipe assembly 202, but also can play a role in draining rainwater.

[0035] When the rainwater is small, the rainwater flows from high to low, at this time the secondary vertical pipe assembly 202 can fully play the function of rainwater collection and guide the rainwater to the water storage unit 3 through the pipeline, improving the collection and utilization efficiency of rainwater; when the rainwater is large, the flow rate of the rainwater will be greatly accelerated, the main vertical pipe assembly 201 can further play a role, when the too fast rainwater passes through the secondary vertical pipe assembly 202, it will overflow the secondary vertical pipe assembly 202 due to the too fast flow rate, and then reach the main vertical pipe assembly 201, the rainwater after passing through the main vertical pipe assembly 201 will be backfilled to the underground rainwater recycling system, avoiding the accumulation of rainwater on the roof, thereby realizing better rainwater drainage effect.

[0036] In another embodiment, as shown in Figure 2 , Figure 3 The shell unit 1 is provided with an outer shell assembly 101 and a convex table 102, wherein the convex table 102 is located inside the outer shell assembly 101, the convex table 102 is arranged at the intermediate position of the top of the main vertical pipe assembly 201 and the secondary vertical pipe assembly 202, and the height of the convex table 102 is 5-15 mm. By arranging the outer shell assembly 101 at the shell unit 1 and arranging the convex table 102 in the outer shell assembly 101, the rainwater can be effectively drained, and during the raining process, the rainwater will flow from high to low, at this time the convex table 102 can effectively block the water flow from the high position of the roof and guide it into the secondary vertical pipe assembly 202, and then into the water storage unit 3, improving the collection efficiency of rainwater; by arranging the convex table 102 between the secondary vertical pipe assembly 202 and the main vertical pipe assembly 201, it can ensure that when the flow rate of rainwater is low, the rainwater will first enter the secondary vertical pipe assembly 202 and be further drained to the water storage system of each floor, improving the utilization efficiency of rainwater. In addition, the height of the convex table 102 is designed in cooperation with the slope of the roof, and is controlled within the range of 5-15 mm, which is suitable for different slopes of the roof, and can effectively block small flow rate rainwater and guide it to the secondary vertical pipe assembly 202 and then to the water storage unit 3, improving the collection and utilization efficiency of rainwater.

[0037] In another embodiment, as shown in Figures 2-4 The ratio between the water inlet diameter of the main vertical pipe assembly 201 and the water inlet diameter of the secondary vertical pipe assembly 202 is (5-8):1. By arranging different water inlet diameters, on the one hand, the secondary vertical pipe assembly 202 can store and drain rainwater when the amount of rainwater is small, and on the other hand, the main vertical pipe assembly 201 can also drain rainwater when the amount of rainwater is large, thereby improving the utilization efficiency of rainwater without causing accumulation of rainwater.

[0038] In another embodiment, as shown in Figure 2 , Figure 5As shown, the secondary vertical pipe assembly 202 includes a first secondary vertical pipe 205, a second secondary vertical pipe 206, and a cross branch 207.

The cross branch 207 is transversely arranged, and the end of the cross branch 207 away from the first secondary vertical pipe 205 is connected to the water storage unit 3. The bottom end of the cross branch 207 is connected to the second secondary vertical pipe 206. The second secondary vertical pipe 206 extends downward and is connected to a bend pipe. The lower end of the bend pipe is connected to the first secondary vertical pipe 205 of the next floor. The above describes the assembly structure and connection relationship between the secondary vertical pipe assembly 202 and the water storage unit 3 in any floor unit. It should be noted that the assembly structure and connection relationship of the secondary vertical pipe assembly 202 and the water storage unit 3 in the above description are consistent in other floor units (except for the top floor and the first floor). The top floor is provided with the housing unit 1 at the top end 4, and the first floor secondary vertical pipe assembly 202 is connected to the main vertical pipe assembly 201. By arranging the first secondary vertical pipe 205 and the second secondary vertical pipe 206 at each floor, a part of the water flow can flow into the water storage unit 3 of the corresponding floor, and the other part of the water flow can continue to flow downward and enter the water storage unit 3 of the corresponding floor on the floor below.

[0039] In another embodiment, as shown in Figure 5 The second secondary vertical pipe 206 is connected to the cross branch 207, and a long strip 208 extending transversely is arranged at the connection position. The cross-sectional area of the long strip 208 is smaller than that of the second secondary vertical pipe 206. By arranging the long strip 208 extending transversely along the cross branch 207, the water flow can be transported to the water storage unit 3 under the condition of small water flow. The long strip 208 is connected to the top end of the second secondary vertical pipe 206, and the cross-sectional area of the long strip 208 is smaller than that of the connection position of the second secondary vertical pipe 206 and the cross branch 207. This can improve the efficiency of rainwater transportation to the water storage unit 3 and also can guide part of the rainwater to the second secondary vertical pipe below to improve the rainwater transportation efficiency.

[0040] In another embodiment, as shown in Figure 5 The ratio of the pipe diameter of the first secondary vertical pipe 205 to the second secondary vertical pipe 206 is 1:(0.5-0.8). By arranging different ratios of the pipe diameter of the first secondary vertical pipe 205 to the second secondary vertical pipe 206, part of the rainwater can be guided through the second secondary vertical pipe when the rainwater flows from the first secondary vertical pipe 205 to the second secondary vertical pipe 206, and part of the water flow can continue to flow along the first secondary vertical pipe to the water storage unit 3 of the corresponding floor.

The water storage pipe 303, away from the electromagnetic valve 301, is further provided with the water inlet valve 302, the water storage tank 304, the water outlet valve 305, and the water using device 306 in sequence in the extending direction. By providing the electromagnetic valve 301 in the water storage unit 3, the opening and closing of the water inlet valve 302 and the water storage valve can be controlled. In addition, the water storage tank 304 can be designed with different capacities according to the needs, which can effectively meet the daily water needs of the residents on each floor and improve the rainwater utilization efficiency. When the rainwater in the water storage tank reaches a certain water level, the electromagnetic valve controls the water inlet valve to be closed, so that the rainwater continues to be transported to the water storage unit on the lower floor along the first vertical pipe and the second vertical pipe.

[0042] In another embodiment, as shown in Figure 2 , the water storage tank 304 is provided with a filter device 307 near the water storage valve, and a water level sensor 308 is arranged in the water storage tank 304. By providing the filter device 307 in the water storage tank 304, the rainwater can be effectively layered and filtered to meet the daily use needs. In addition, the water level sensor 308 is also arranged in the water storage tank 304, which can effectively measure the water level height in the water storage tank 304. When the height reaches a certain height, the opening and closing of the water inlet valve 302 is controlled by the electromagnetic valve 301, realizing the rainwater collection in each corresponding floor water storage tank 304 without power.

[0043] In another embodiment, as shown in Figure 2 , the water storage unit 3 is arranged in each floor of the high-rise building, and the water storage unit 3 is arranged about 100-200 mm below the top of each floor. By arranging the water storage tank 304 at a higher position on the corresponding floor, the residents' daily water use can be powered, and the rainwater can be collected and used without additional power, improving the utilization efficiency of rainwater.

[0044] In another embodiment, as shown in Figure 2 , Figure 4 , the outer shell assembly 101 is provided with a plurality of water inlet holes 103 and is fixedly arranged at the top of the floor 4. The outer shell assembly 101 and the convex table 102 are designed as a whole.
