A safety warning device for sewer water flow in heavy rainfall weather

Abstract

The invention discloses a safety early warning device for sewer flow in the heavy rainfall weather. The safety early warning device for sewer flow in the heavy rainfall weather comprises a sensor waterproof fixing device and a flow speed pressure difference sensor assembly, wherein the sensor waterproof fixing device is horizontally arranged at the intersection of a horizontal water drain pipeline portion and a well lid lower vertical water drain pipeline portion and comprises a rectangular waterproof containing shell; sealing rings are arranged on round through holes in the front end of the waterproof containing shell; a waterproof shockproof layer is arranged on the inner wall; the waterproof containing shell is internally and sequentially provided with a first waterproof partition board, a second waterproof partition board and a third waterproof partition board in the length direction; the three partition boards divide the interior of the waterproof containing shell into four mutually waterproof cavities. A sensor is arranged in the waterproof containing shell, the waterproof performance is enhanced, water enters two of the cavities through the round holes after the device is used for a long time and will not affect the core component of the sensor, the waterproof performance of the sensor is enhanced, the service life is prolonged, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline safety inspection system devices, in particular to a sewer water flow safety early warning device in heavy rainfall weather Background technique [0002] The normal operation of the detection device of the urban underground waterway plays a very important role in guaranteeing the urban wastewater treatment and transportation. The safety detection of the sewer is to have various sensors transmit the detected data to the monitoring center through the communication medium for analysis and processing, to achieve For the purpose of monitoring, the sensor is used to detect relevant data such as water flow rate and water rise height in the sewer pipe, and is used for analysis and alarm. The waterproof performance of the sensor directly affects the detection accuracy of the sensor. [0003] At present, during the normal use of the sensors used for the safety detection of sewer pipes, due to frequent cont...

AI Technical Summary

Problems solved by technology

[0003] At present, during the normal use of the sensors used for the safety detection of sewer pipes, due to frequent contact with water, the accuracy of the monitoring data of the sensors used is greatly affected, and the failure rate and maintenance cost are also high, especially in heavy rainfall days. , the water flow in the sewer pipe is turbulent, which has a great impact on the sensor, which greatly reduces the service life of the sensor
