Sensor intermittent type automatic brushing and cleaning device

Abstract

The invention provides a sensor intermittent type automatic brushing and cleaning device. The sensor intermittent type automatic brushing and cleaning device comprises a fixing frame, a cleaning wheel, an intermittent linkage device and a driving device, wherein the fixing frame, the cleaning wheel, the intermittent linkage device and the driving device are fixedly installed together with the sensor. The sensor intermittent type automatic brushing and cleaning device can perform intermittent type brushing and cleaning on the sensor and does not need to be in contact with the sensor at all times, the measurement sensitivity of the sensor is improved, and the probability of damage or breakdown to the sensor during cleaning is reduced. When the dirt does not form a stable state, brushing andcleaning are carried out in time without affecting the real-time measurement of the sensor, and the defect of inaccurate trend of historical data due to the fact cleaning is started only after the sensitivity of the sensor decreases is overcome, and the sensor intermittent type automatic brushing and cleaning device is more advantageous than regular, centralized and high-intensity automatic brushing and cleaning in the prior art.

Description

technical field [0001] The invention relates to an automatic scrubbing device, in particular to a sensor intermittent automatic scrubbing device. Background technique [0002] In the fields of ecological environment monitoring, water resources monitoring, water quality monitoring and other fields, almost all water quality parameter measurement sensors must be cleaned regularly. Because after the sensor works underwater for a period of time, some dirt, impurities or mucus will be adsorbed on the surface of various parts of the sensor, especially the sensors used in the aquaculture field, which need to be cleaned regularly. Since the sensitive element of the sensor generally needs to be in direct contact with the medium, and this kind of dirt and impurities will affect the full contact of the contact part, if it is not cleaned or wiped in time, the measurement result will be inaccurate or severely lagged. [0003] In the prior art, on-site workers are generally required to do...

AI Technical Summary

Problems solved by technology

Since the return device uses a spring and works underwater, the working life of the spring will be greatly reduced

At the same time, spraying air directly on the front of the underwater probe of the sensor is likely to cause damage to the sensor
