Automatic sewage collection system for urban drainage pipe network and control method thereof

Abstract

The invention relates to an automatic sewage collection system for an urban drainage pipe network and a control method thereof. The system comprises an automatic water pumping device, a rotary water injection device, a rotary arm automatic driving device, sample collecting devices, a box body for supporting the whole system and a power supply for supplying power to the whole system; a number of sample collecting devices are arranged; the rotary water injection device is connected with the automatic water pumping device and the sample collecting devices; the rotary water injection device is driven by the rotary arm automatic driving device, and the water injection end of the rotary water injection device matches the positions of the sample collecting devices; the sample collecting devices are connected with a liquid level sensor; the automatic water pumping device is connected with a time control switch, and the liquid level sensor is connected with the time control switch and the rotary arm automatic driving device; the box body is connected with a lifting ring; and the lifting ring is used for suspending the system in a sewage collection area through a rope. Compared with the prior art, the system provided by the invention has the advantages of simple processing, low cost, safety, reliability and the like, and is beneficial to promoting the improvement of urban water environment quality.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an automatic collection system for urban drainage pipe network sewage and a control method thereof. Background technique [0002] With the rapid development of my country's social economy, the urban sewage collection rate is gradually increasing, but the water environment quality in many cities has not been significantly improved. One of the main reasons is the overflow sewage discharge in the urban drainage pipe network. There are many reasons for the overflow of sewage in the drainage pipe network, mainly including: mixed connection of rainwater and sewage pipe systems, wrong connection caused sewage overflow in rainwater system in dry weather, groundwater and transfer water in the upstream pipe network exceed the downstream collection Sewage overflow in dry days caused by the storage and drainage capacity of the system, and sewage overflow in rainy days caused...

AI Technical Summary

Problems solved by technology

However, the drainage system is often laid along the road. The traditional method of collecting by opening the manhole cover requires a lot of manpower, material and financial resources, which will not only cause urban traffic congestion, but also endanger the personal safety of the sampling personnel.
