[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] The present utility model provides a technical solution:
[0020] Please refer to Figures 1-4 , a suspended rainwater collection device based on a building, which includes a water storage tank 1. The water storage tank 1 is installed at a high position on the outer facade of the building through a bracket 11 and an expansion screw 13. During construction, it can be shielded by the outer layer of the building. Connect the building drain pipe 2 to the upper end of the water storage tank 1. The rainwater on the bottom floor is concentrated and enters the water storage tank 1 through the building drain pipe 2. And a drain valve 7 is connected to one side of the water storage tank 1, and the drain valve 7 is connected to a drain pipe 8. An overflow port 3 is installed at the top of the other side of the water storage tank 1. When the water in the water storage tank 1 is full, it can be automatically discharged through the overflow port 3;
[0021] Among them, the lower part of the water storage tank 1 is in a necked shape, and a drainage valve 5 is connected to the lower part. The outlet end of the drainage valve 5 is connected to a drainage pipe 6. The drainage valve 5 can discharge the precipitated dirt in the tank body. When the rainfall is large, the drainage pipe 6, the water storage tank 1 and the building drain pipe 2 together form the original drainage pipe of the building. In the case of heavy rain, the rainwater can be directly discharged to the drainage system at the bottom of the building by using the three of them.
[0022] The water discharge valve 7 is installed at the waist of the water storage tank 1. The outlet end of the water discharge pipe 8 is connected with an interface 9 to prevent the dirt deposited at the bottom of the tank body from entering the water discharge pipe 8. When it is necessary to use the water in the tank to water the greenery around the building or for other water uses, an external water pipe can be connected to the interface 9 for water use. Since the tank body is at a high place, the water collected inside can be directly discharged by using the potential energy.
[0023] Among them, the outlet end of the overflow port 3 is connected with an overflow pipe 4, and the outlet end of the overflow pipe 4 is connected with the sewage discharge pipe 6. The overflowed water enters the sewage discharge pipe 6. A check valve is provided at the connection to prevent backflow. A tank cover 10 is installed on the top of the water storage tank 1. By opening the tank cover 10, the inside of the tank body can be cleaned.
[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
