[0002] In some factories or enterprises with large water consumption, such as power plants, it is necessary to set up independent water reservoirs and pump houses for daily water use. Generally, for the sake of structural strength, water storage capacity and construction cost, large-capacity water reservoirs are usually obtained by digging downward from the ground, and the pump house, as a centralized control place for water pumps, is generally semi-underground or above-ground. This structure has certain problems, that is, the height of the water inlet main pipe is higher than the bottom height of the water reservoir. When the water level of the water reservoir is lower than a certain height, it will be lower than the position of the water inlet main pipe. It is difficult for each pump group to absorb water, and the pump group cannot operate normally, posing certain safety hazards. Utility Model Content

The first end is connected to the bottom of the water reservoir, the first water inlet pipe is provided with a first control valve, the second water inlet pipe is provided with a second control valve, the bottom surface of the water reservoir is lower than the water pumping pipe, the water pumping pipe is lower than the bottom surface of the vacuum water diversion chamber, the vacuum water diversion chamber is a closed cavity, the top of the vacuum water diversion chamber is provided with a vacuum pump and an exhaust pipe, the exhaust pipe is provided with a third control valve, one end of the vacuum water pumping pipe is connected to the top of the side wall of the vacuum water diversion chamber, and the other end of the vacuum water pumping pipe is connected to the bottom of the water reservoir.

[0007] Furthermore, it also includes a controller, a liquid level detection device is provided in the water reservoir, and the controller is electrically connected to the liquid level detection device, the first control valve, the second control valve and the third control valve respectively.
[0008] When the pumping system of the pump room is performing pumping operations, when the water level of the water reservoir is higher than the pumping pipe, the first control valve can be closed and the second control valve can be opened to directly pump water from the water reservoir through the second water inlet pipe. When the water level of the water reservoir is lower than the pumping pipe, there is a problem of difficulty in pumping water. The vacuum water diversion chamber can be evacuated by the vacuum pump to pump water in the water reservoir into the vacuum water diversion chamber through the vacuum effect, and then the first control valve and the third control pump can be opened, the second control valve can be closed, and water can be pumped from the vacuum water diversion chamber through the first water inlet pipe. Since the vacuum water diversion chamber itself is higher than the pumping pipe, it can be used in an emergency at low water levels to avoid the problem of difficulty in pumping water.
