Description

Drainage pipe network pre-emptying waterlogging prevention system based on storm early warning and water level linkage Technical Field The invention belongs to the technical field of urban drainage and urban waterlogging prevention, and particularly relates to a drainage pipe network pre-emptying waterlogging prevention system based on storm warning and water level linkage. Background Under the dual actions of global climate change and rapid urban land, urban waterlogging has become a serious "urban illness" which threatens urban safe operation and affects life and property safety of residents. In the urban expansion process, even if the diversion transformation of rain and sewage is completed, the temporary waterlogging of the rainstorm can still occur. On one hand, the urban is expanded outwards to promote the growth of a large number of watertight pavements, the surface runoff coefficient is obviously increased, the flood process line is characterized by being high, sharp and thin, and a large amount of rainwater formed in a short time is easy to cause waterlogging. Meanwhile, the inventor finds that in the implementation process, the existing rainwater diversion design is set according to local parameters, but the drainage capacity is poorer and worse after a period of operation. Disclosure of Invention The invention aims to provide a drainage pipe network pre-emptying waterlogging prevention system based on storm warning and water level linkage, and aims to solve the problem that the conventional rainwater diversion drainage capacity is difficult to normally exert. In order to achieve the purpose, the technical scheme adopted by the invention is that the drainage pipe network pre-emptying waterlogging prevention system based on storm warning and water level linkage is provided, and the drainage pipe network pre-emptying waterlogging prevention system comprises: The weather early warning unit is used for receiving weather information; The pipeline liquid level monitoring unit is used for monitoring the water level in the rainwater pipe; The reservoir water level monitoring unit is used for monitoring the water level of the reservoir of the pump station; a water discharge device for discharging water in the reservoir; And the controller is configured to start the drainage device in advance when the weather early warning unit responds to heavy rain or heavy rain in the future, and gradually drain or lower accumulated water in the reservoir and the rainwater pipeline to a preset low position. Further, the drainage device is a pump group consisting of a plurality of drainage pumps; the controller is configured to control different numbers of drainage pumps according to the data of the pipeline liquid level monitoring unit and the water level monitoring unit of the reservoir, so that the drainage capacity is dynamically matched with the incoming water quantity. Further, at least one drain pump is a variable frequency speed pump. Further, the controller is configured to control the drainage device to drain or lower the accumulated water in the reservoir and the rainwater pipeline to a low position, and continuously run, so that the water in the saturated soil/sand around the rainwater pipeline gradually seeps out and is drawn out, and a double regulation space of the space in the pipeline and the soil outside the pipeline is formed. Further, the controller is configured to progressively increase the number of operating drain pumps from low to high in response to reservoir water level height information during rainfall, progressively decreasing the number of operating water pumps as the water level drops. Further, the controller is configured to analyze the liquid level change speeds of the pipe liquid level monitoring unit and the reservoir liquid level monitoring unit, and to increase the number of running drain pumps when the liquid level change speed monitored by the pipe liquid level monitoring unit is greater than the liquid level change speed monitored by the reservoir liquid level monitoring unit. Further, the controller is configured to activate the drainage device in advance to gradually drain or lower the accumulated water in the reservoir and the rainwater pipeline to a preset low level when the weather early warning unit responds to heavy rain or heavy rain occurring in the future 1-3 days.
