The liquid level sensor 12 is connected to the control device, and the control device makes the water tank set by the liquid level sensor 12 The water level upper limit and the water level lower limit in 1 are associated with the water pump 3, and the association relationship is: the water pump 3 stops when the water level in the water tank 1 reaches the upper limit, and the water pump 3 starts when the water level in the water tank 1 reaches the lower limit.

The water tank 1 is provided with a water outlet pipe 13, and the water outlet pipe 13 is connected with the water inlet of the water collection tank in at least one water collection device 4 connected to the flushing water tank with secondary water provided in each toilet in each floor of the building, and the water collection The water inlet pipeline of the water tank is connected with a valve, and a liquid level controller is set in the water collecting tank to be associated with the valve, so that when the water level in the water collecting tank reaches the lower limit, the valve opens, and when the water level in the water collecting tank reaches the upper limit, the dynamic valve closes.

The water collecting device used in this embodiment is a Chinese patent with the patent number ZL200610086480.3 that provides a graded water device for domestic water classification, which selectively collects the drainage of domestic water into a water collector. A cleanliness identifier is installed on the inlet pipe of the water collector to identify the cleanliness of the domestic water drainage. The water that meets the cleanliness requirements passes through and enters the water collection tank. When the water with low cleanliness passes through, it leads to the drain pipe of the sewer. The electric valve on the top is opened, and the water is discharged directly into the sewer.

The outlet pipe 13 in the secondary water utilization device utilizing rainwater provided by the utility model is connected to the water inlet pipe of the water collector, and the outlet pipe 13 can be connected in front of the cleanliness identifier to allow the rainwater to identify the cleanliness, and can also be connected to the cleanliness behind the degree identifier, so that rainwater does not pass through the cleanliness identification.

The liquid level sensor in the water collection tank can control the electric valve that is arranged on the outlet pipe 13, so that the electric valve opens when the water is short of water in the water collection tank, and the electric valve closes when the water in the water collection tank is full.

The water collecting tank used by the utility model can also be that no electric valve is set on the water outlet pipe 13, a float valve is set at the water inlet of the water collecting tank, and the rainwater is controlled to enter the water collecting tank through the float valve, and a manual valve is set on the water outlet pipe 13 41, so that the water collection tank is connected or disconnected with the secondary water utilization device utilizing rainwater provided by the utility model.

In use, start the water pump 3, the rainwater stored in the rain flood cellar can be sent to the water tank on the top of the building, and the water in the water tank is delivered to the collection of the toilet flushing water tank in the building through the water tank outlet pipe. In the water collection tank in the water device, the water outlet of the water collection tank is connected to the toilet flushing water tank through a connecting pipe.

In the water tank 1, a disinfection device (not shown) is set, that is, a container with a cover is fixed in the tank, and a through hole or slit is provided on the side wall of the container. During use, a solid disinfectant is put into the container, which is slowly released in contact with the water in the tank to disinfect and sterilize the rainwater in the tank.

An overflow device is also provided in the water tank, which includes a water outlet arranged above the upper limit water level line of the tank, and an overflow pipe 14 is connected to the water outlet. In use, the overflow pipe communicates with the sewer.

The water outlet pipe on the water tank 1 is a pipe network line, including several water outlet pipe ports, connected with the water collecting tank in the water collecting device 4 provided at the washbasin of each toilet in each floor in the building.

A check valve 1a is provided on the water tank inlet pipe connected to the water outlet of the water pump 1 .

The valve connected to the water inlet pipeline in the water collection tank and the liquid level controller set in the water collection tank can be as in the ZL200610086480.3 patent, the electric valve set on the water inlet pipeline, the liquid level sensor set in the water collection tank sense controller. It is also possible to set a float valve in the water collection tank as a valve on the water inlet pipeline and a liquid level controller in the water collection tank.

The top of the water tank 1 can be provided with an openable tank cover. In use, when it rains, the box cover can be opened to allow rainwater to supplement the water quantity in the water tank. This reduces the number of pump starts and saves energy.

Since rainwater after treatment belongs to the category of secondary water reuse, it can only be used in toilet flushing, cleaning, greening, etc., so special pipelines and special equipment should be designed to complete the work in the use link.
