Drop well online monitoring and early warning system

Abstract

The invention provides a drop well online monitoring and early warning system which comprises a drop well body, wherein a water inlet pipe is arranged on the upper portion of the side wall of the drop well body, and a water outlet pipe is arranged on the lower portion of the side wall opposite to the water inlet pipe. The system further comprises a water quality monitoring sensor used for monitoring the sewage quality condition, a gas monitoring sensor used for monitoring the harmful gas condition in the drop well body and generating an electric signal, an infrared reflection sensor used for monitoring the well lid condition, a controller connected with the three sensors, an alarm device and a positioning device which are connected with the controller, a storage battery used for providing electric energy, and a hydroelectric generation device used for generating electricity by utilizing sewage flow energy and charging the storage battery. According to the invention, self-sufficient energy is utilized, the sewage quality condition, the harmful gas condition in the well and the well lid condition can be monitored in real time at the same time, and an alarm can be given in time when unfavorable conditions are monitored, so that the purposes of protecting the environment and maintaining pipeline safety and well lid safety are achieved.

Description

technical field [0001] The invention relates to the technical field of sewage monitoring, in particular to an online monitoring and early warning system for a water drop well. Background technique [0002] The sewage pipeline system consists of pipelines for collecting and transporting urban sewage and its subsidiary structures. Sewage flows into the main pipe from the branch pipe, then into the main pipe, and finally into the sewage treatment plant. The pipes range from small to large, distributed like rivers and branched. Sewage in the pipeline generally depends on the water surface difference at both ends of the pipeline to flow from high to low, that is, by gravity. At present, in the design and construction of engineering projects, the sewage drainage system often uses falling wells to solve the energy dissipation problem of gravity flow drainage with excessive height difference. In mountainous cities, due to the large terrain drop, the application of falling water w...

AI Technical Summary

Problems solved by technology

However, at present, the gas in the sewage pipeline can be monitored online, but there is an economic problem of power consumption, and it cannot be effectively popularized in economically underdeveloped areas.

[0005] In addition, in the sewage discharge system, the loss and damage of sewage manhole covers are still very common, because the incidents of manhole cover loss or damage are not uncommon and cause personal injury, which has an adverse impact on people's life safety and public order
