Sensor head with self sterilization and cleaning functions

Abstract

The invention provides a sensor head with self sterilization and cleaning functions. The sensor head comprises a sensor body provided with an intelligent control cavity, a moisture cavity and a measuring device cavity; and a brushing device used for brushing washing and a sterilization jetting device used for jetting washing are arranged at the lower end of the sensor body. The sensor head integrates the two modes of brushing washing and sterilization jetting washing, the flexibility and the precision of measurement of the sensor can be improved, the regular maintenance period of the sensor can be reduced, and thus the sensor cannot be easily damaged. Meanwhile, the historic data of the whole measuring interval are constant, reliable and precise data. The sensor head breaks through the conventional sensor design, a measuring sensitive area is arranged on one side of the bottom part of the sensor head, brushing washing and jetting washing are easier, the sensor head is widely applied, and can adapt to more measuring occasions.

Description

technical field [0001] The invention relates to a sensor head, in particular to a self-sterilizing and cleaning sensor head. Background technique [0002] In the fields of water resources and water quality monitoring, it is generally necessary to place relevant sensor heads at a certain distance underwater to measure relevant parameters in the water in real time for analysis and processing. In the scene that requires long-term online monitoring, since the sensor is placed underwater for a long time, the surface of each part of the sensor will absorb some dirt, impurities or mucus, etc., which is more obvious in the field of aquaculture. If the sensor is not cleaned at this time , will seriously affect the accuracy of the measurement results. [0003] Existing various water quality measurement sensors generally need to go to the site regularly to clean and maintain them manually, resulting in a large waste of manpower and material resources, and generally wait until the data...

AI Technical Summary

Problems solved by technology

These cleaning devices generally also need to be equipped with additional controllers. Since the sensor is a separate structure, it is difficult to unify the control part of the sensor with the control part of the cleaning device. The cost is relatively high

[0005] At the same time, in the prior art, the water quality measurement sensor is basically uniformly set the measurement sensitive area on the central axis of the sensor, which leads to limitations in the design of the cleaning device, and it is not easy to fully display it.

[0006] The existing cleaning devices for external water quality sensors generally only have a cleaning function, and have not started from a more basic point to achieve sterilized cleaning
