Filter screen for monitoring water quality

Abstract

The invention discloses a filter screen for monitoring water quality. The filter screen comprises a filter screen body, wherein an integrated pipe is fixed on the side wall of one side of the filter screen body, a flow guide unit connected with the end part of the integrated pipe is arranged on the inner wall of the filter screen body, a piston is arranged in the integrated pipe in a sliding manner, a connecting rod is fixed on the inner side wall of the piston, electric contact ends are fixed at the end part of the connecting rod and on the inner wall of the integrated pipe, an air bag is further fixed between the piston and the inner wall of the integrated pipe, a connecting link I is fixed on the upper side wall of the filter screen body, a rotating disc is mounted at the upper end of the connecting link I, multiple fan blades are uniformly distributed on the outer wall of the rotating disc, a cam is fixed on the outer wall of the rotating disc, and a connecting rod II is also fixedon the outer wall of the filter screen body. According to the filter screen, connection of an alarm is realized when too many impurities exist on the surface of the underwater filter screen, electriccurrent is produced through rotation of the rotating disc, and then the filter screen is cleaned by means of working prompt of the alarm.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a filter screen for water quality monitoring. Background technique [0002] Groundwater quality monitoring refers to the monitoring and determination of the types, concentrations and changing trends of harmful substances in groundwater, evaluating and mastering the pollution status of groundwater, and understanding the status of groundwater quality and the trend of pollution development. [0003] In the water quality detection project, water quality sensors are generally used to monitor water quality. At the same time, it is necessary to filter the monitored water source through a filter and absorb and settle impurities and bacteria to realize the use of water after filtration. However, the traditional underwater The filter screen cannot monitor the impurities on the surface of the filter screen in real time. When there are too many impurities, it will easily aff...

[0003] In the water quality detection project, water quality sensors are generally used to monitor water quality. At the same time, it is necessary to filter the monitored water source through a filter and absorb and settle impurities and bacteria to realize the use of water after filtration. However, the traditional underwater The filter screen cannot monitor the impurities on the surface of the filter screen in real time. When there are too many impurities, it will easily affect the filtration of water, and human beings cannot find them in time.
