Description

Technical Field

[0001] The utility model relates to the technical field of water supply tanks, in particular to a secondary water supply overflow protection device. Background Art

[0002] The secondary water supply is to pump the city's public water supply or self-built facilities water to high-rise buildings through pipelines and then supply it to users or for self-use. Generally, the ground water is pumped to the water tank installed in the high-rise building, and the water in the water tank is used to supply it to users.

[0003] When the existing water tank is filled with water, it is transported through a water pump and a water pipe. People need to observe the water tank. When the water inside the water tank is full, the water pump is turned off. The above method requires people to constantly monitor the water tank, which is also easy to cause the water inside the water tank to overflow after it is full, resulting in a waste of water resources and labor costs. Therefore, it is urgent to design a secondary water supply overflow protection device to solve the above problems. Utility Model Content
