[0021] Example 1: Figure 1 As shown, a rainwater recycling system for layered buildings includes a rainwater collection module, a rooftop water collection module and a plurality of in-layer water collection modules respectively arranged on each layer of the layered building.

[0022] The rainwater collection module includes a rainwater filter 1 and a rainwater tank 2. The rainwater filter 1 is arranged on the bottom surface of the roof of the layered building. The rainwater filter 1 is used to collect and filter rainwater on the roof. The rainwater filter 1 is connected to the rainwater tank 2. The rainwater tank 2 is arranged on the highest floor. The rainwater tank 2 is respectively connected to the roof water collection module and the adjacent layer water collection module. A one-way valve for controlling the one-way external output of the rainwater tank 2 is arranged between the rainwater tank 2 and the adjacent layer water collection module. A driving water pump 3 is arranged in the rainwater tank 2. The driving water pump 3 is used to control the rainwater in the rainwater tank 2 to enter the roof water collection module.

[0023] The rooftop water collection module includes a rooftop water collection tank 4 and a rainwater pipe 5 connected to each layer of the layered building. A filter device 11 is provided between the rooftop water collection tank 4 and the rainwater tank 2. The rainwater tank 2, the filter device 11, the one-way valve, and the rooftop water collection tank 4 are connected in sequence. A first liquid level sensor 6 connected to a driving water pump 3 is provided in the rooftop water collection tank 4. When the first liquid level sensor 6 detects that the water level of the rooftop water collection tank 4 is lower than a first set value, the driving water pump 3 can be started. When the first liquid level sensor 6 detects that the water level of the rooftop water collection tank 4 is higher than the first set value, the driving water pump 3 stops inputting rainwater in the rainwater tank 2 into the rooftop water collection tank 4. The rainwater pipe 5 is provided with a clean water valve 7 for controlling the water outlet on each layer of the layered building. There are multiple rooftop water collecting tanks 4, one of which is provided with a rooftop overflow device, the rooftop overflow device includes a rooftop overflow pipe 12, and the rooftop overflow pipe 12 is connected to the upper part of the rooftop water collecting tank 4 through a rooftop overflow port.

[0024] The multiple in-layer water collection modules all include an in-layer water collection tank 8, the in-layer water collection tank 8 is connected to a rainwater valve 9 and an in-layer overflow device, the rainwater valve 9 is used to control the rainwater output, the rainwater valve 9 is connected to the toilets of each layer or is directly used for cleaning the bottom surface. The in-layer overflow device includes an in-layer overflow pipe 10 connected to the upper part of the in-layer water collection tank 8, the in-layer overflow pipe 10 is connected to the in-layer water collection tank 8 in the adjacent lower layer, and the in-layer overflow pipe 10 of the in-layer water collection tank 8 of the lowest layer is connected to the rainwater drainage pipe. The rooftop water collection tank 4 and the in-layer water collection tank 8 are both equipped with an immersion sterilizer.

[0025] The roof of the layered building is provided with interconnected solar photovoltaic panels 13 and power storage devices 14. The solar photovoltaic panels 13 are fixedly installed on the roof through a fixed frame, and the power storage device 14 is fixedly installed on the fixed frame. The power storage device 14 is connected to the first liquid level sensor 6 and the driving water pump 3.

[0026] Operating principle: Figure 1As shown, rainwater falls to the roof and is initially filtered through the rainwater filter net 1 into the rainwater tank 2. When the first liquid level sensor 6 detects that the water level of the rooftop water collection tank 4 is lower than the first set value, the driving water pump 3 can be started. At this time, the driving water pump 3 can be manually started. The driving water pump 3 filters the rainwater in the rainwater tank 2 through the filtering device 11 and transports it unidirectionally to each rooftop water collection tank 4. The rooftop water collection tank 4 provides corresponding clean water for each floor through the rainwater pipe 5 and the clean water valve 7 of each floor.

[0027] When the first liquid level sensor 6 detects that the water level of the rooftop water collecting tank 4 is higher than the first set value, the water pump 3 is driven to stop inputting the rainwater in the rainwater tank 2 into the rooftop water collecting tank 4. At this time, as the rainwater continues to increase, the rainwater in the rainwater tank 2 overflows into the intra-layer water collecting tank 8 on the same floor. The intra-layer water collecting tank 8 can supply water to each floor through the rainwater valve 9. The water can be used for cleaning and flushing the toilet or the bottom surface. The intra-layer water collecting tank 8 continues to overflow with the increase of rainwater volume. The overflowing rainwater flows into the intra-layer water collecting tank 8 of the adjacent lower layer, realizing batch storage of the center layer by layer, and the overflowing rainwater in the intra-layer water collecting tank 8 of the lowest layer is directly discharged.

[0028] Embodiment 2: Embodiment 2 realizes further automatic control relative to Embodiment 1. Relative to the technical solution of Embodiment 1, Embodiment 2 also includes a control center 16, and the control center 16 is respectively connected to the driving water pump 3, the first liquid level sensor 6 and the power storage device 14, and a second liquid level sensor 15 connected to the control center 16 is arranged in the rainwater tank 2. The power storage device 14 and the control center 16 of the present application are both arranged on a fixed bracket, and their positions are higher than the ground, so they can avoid being penetrated by rainwater. The fixed bracket is located below the solar photovoltaic panel 13 to provide support for the solar photovoltaic panel 13, so the solar photovoltaic panel 13 shields the second liquid level sensor of the control center 16, which can prevent rainwater from directly hitting the second liquid level sensor 15 of the control center 16.

[0029] When rainwater falls to the roof, it is initially filtered through the rainwater filter 1 and then flows into the rainwater tank 2. When the second liquid level sensor 15 in the rainwater tank 2 is higher than the second set value and the first liquid level sensor 6 detects that the water level in the rooftop water collection tank 4 is lower than the first set value, the control center 16 starts the driving water pump 3. The driving water pump 3 filters the rainwater in the rainwater tank 2 through the filtering device 11 and transports it to each rooftop water collection tank 4 in one direction. The rooftop water collection tank 4 provides corresponding clean water to each floor through the rainwater pipe 5 and the clean water valve 7 of each floor.

[0030] When the first liquid level sensor 6 detects that the water level of the rooftop water collection tank 4 is higher than the first set value, the control center 16 stops driving the water pump 3 to input the rainwater in the rainwater tank 2 into the rooftop water collection tank 4. At this time, as the rainwater continues to increase, the rainwater in the rainwater tank 2 overflows into the water collection tank 8 on the same floor. The water collection tank 8 on the floor can supply water to each floor through the rainwater valve 9. The water can be used for cleaning and flushing the toilet or the bottom surface. The water collection tank 8 on the floor continues to overflow as the amount of rainwater increases. The overflowing rainwater flows into the water collection tank 8 on the adjacent lower floor, realizing batch storage of the center layer by layer, and the overflowing rainwater in the water collection tank 8 on the bottom floor is directly discharged. The clean water described in this application refers to rainwater that has only been filtered by the rainwater filter 1, and does not mean that the clean water is pure water. The rooftop water collection tank 4 and the water collection tank 8 on the floor described in this application are not necessarily three-dimensional outwardly protruding water tanks, but can also be structures such as pools set on the bottom.

[0031] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to provide exhaustive examples of all implementation methods here.
