Vacuum rainwater drainage system and method

Abstract

The invention discloses a vacuum rainwater drainage system and a method. The system comprises a pump room, a water colleting tank, a water inlet pipe, a water outlet pipe and a water drainage river channel, wherein one end of the pump room is connected with the water colleting tank through the water inlet pipe, and the other end is connected with the water drainage river channel through a water outlet pipe; an electrical control unit and at least one vacuum control pump group is arranged in the pump room, and the electrical control unit controls the vacuum control pump group; and a liquid level measurement unit is arranged in the water collecting tank, and the liquid level measurement unit outputs signals to the electrical unit. The system and the method have the advantages that the starting of the pump unit requires no filling water, and the working efficiency is high; and the operation vibration of the device is low, and the failure rate is low; connecting pipes can be turned around, underground structures can be avoided, and the problem that construction is hard due to underground pipe networks are complex is solved effectively; capacity of a variable frequency regulation pump can be detected through a double-acting liquid level, and the performance of the system is reliable; and after the system control is upgraded, unmanned management of a pump station can be achieved, and management and human resource costs are saved.

Description

technical field [0001] The invention relates to a municipal drainage pumping station, in particular to a vacuum rainwater drainage system and method. technical background [0002] As the trend of global warming further intensifies, sudden and disastrous weather such as heavy rainfall, heavy rain, and typhoon frequently occurs, which brings great pressure on the drainage and overflow of modern cities. After heavy rainfall in many large and medium-sized cities, the problem of water accumulation in old urban areas, tourist attractions, and low-lying areas is serious. . Especially in provinces and cities with dense urban buildings, the problem of water accumulation on roads is more prominent, which seriously affects the daily life of citizens. [0003] The most direct cause of ponding is due to insufficient drainage capacity of drainage facilities. Within a certain period of time, the actual runoff generated is greater than the allowable discharge of drainage facilities, formi...
