Pipe network overflow port anti-backflow device
The invention discloses an anti-backflow device for an overflow port of a pipe network. The anti-backflow device comprises an in-well liquid level meter, a drainage pipeline and a water level liquid level meter, a drainage port of the drainage pipeline is provided with a pipe nozzle with controllable opening and closing; a water flow booster pump is arranged in the pipe nozzle; when it is measured that the external water level is lower than a first preset value, the pipe network overflow port anti-backflow device is used for controlling the pipe nozzle to be opened, and it is ensured that internal sewage can be discharged in time; when it is detected that the external water level reaches or is higher than a first preset value, the pipe network overflow port anti-backflow device is used for controlling the pipe nozzle to be closed, and river water can be prevented from flowing backwards into the sewage discharging system; when the external water level reaches or is higher than the first preset value and the internal water level reaches or is higher than the second preset value, the pipe network overflow port anti-backflow device is used for starting the water flow booster pump to discharge water outwards, and waterlogging caused by the fact that the internal water level of the sewage discharge system is too high is avoided. Therefore, the problem that river water backflow and waterlogging cannot be solved at the same time in the prior art is practically solved.
本发明公开了一种管网溢流口防倒灌装置，包括井内液位计、排水管道、以及水位液位计；排水管道的排水口设有开闭可控的管嘴；管嘴内设有水流增压泵；在测得外部水位低于第一预设值时，管网溢流口防倒灌装置用于控制管嘴打开，确保能够实现内部污水的及时排放；在测得外部水位达到或高于第一预设值时，管网溢流口防倒灌装置用于控制管嘴关闭，则可防止河水倒灌至排污系统内部；在测得外部水位达到或高于第一预设值、且内部水位达到或高于第二预设值时，管网溢流口防倒灌装置用于启动水流增压泵往外排水，避免排污系统内部水位过高从而发生内涝，从而切实解决了现有技术无法同时解决河水倒灌和内涝的问题。
