Sensor surface automatic cleaning device

Abstract

The invention discloses an automatic cleaning device for the surface of a sensor, which is characterized in that a rotating impeller is arranged on a port on the head of a high-pressure water pipe, and the rotating impeller and the high-pressure water pipe form clearance fit; an axial elastic pressing piece is arranged between the rotating impeller and the high-pressure water pipe; blades are arranged on the circumference of the rotating impeller; the impeller is provided with an axial water outlet opening; the outer end face of the rotating impeller is provided with a chorionic strip; the head of the high-pressure water pipe is provided with a pipe orifice which is aligned to a spray pipe of the blades; and various members are made of corrosion and abrasion resistant materials. The device has a simple structure and good cleaning effect, adopts mechanical members, has good corrosion and abrasion resistance, can be arranged under water, is used for automatically cleaning the surface of an underwater sensor, is simple and convenient to operate, and can meet the demand of online instruments for on-scene monitoring.

Description

technical field [0001] The invention relates to an automatic sensor surface cleaning device for cleaning the surface of an underwater sensor of an online instrument. Background technique [0002] In many on-site monitoring, the sensor of the online instrument is installed underwater. Due to the pollution of the measured body and the needs of the sensor itself, the surface of the sensor must be cleaned regularly. If the operator goes to the site to clean it, it is cumbersome and time-consuming. It is difficult to operate, and if it is not cleaned, it will be difficult to ensure the accuracy of the measurement, and even cause the entire system to fail to work properly. [0003] At present, there are roughly two types of automatic cleaning devices used in the market. One is to use water pipes to wash the surface of the sensor with water, but the washing effect is very poor; the other is to use ultrasonic cleaning, which is difficult to install underwater. And the expected effe...

[0002] In many on-site monitoring, the sensor of the online instrument is installed underwater. Due to the pollution of the measured body and the needs of the sensor itself, the surface of the sensor must be cleaned regularly. If the operator goes to the site to clean it, it is cumbersome and time-consuming. It is difficult to operate, if it is not cleaned, it is difficult to ensure the accuracy of the measurement, and even cause the entire system to not work properly

[0003] At present, there are roughly two types of automatic cleaning devices used in the market. One is to use water pipes to wash the surface of the sensor with water, but the washing effect is very poor; the other is to use ultrasonic cleaning, which is difficult to install underwater. And the expected effect cannot be achieved underwater

Therefore, most of the on-line instruments currently on the market do not have automatic cleaning devices, which makes the maintenance of on-line instruments very difficult, thus affecting the use effect of the entire instrument
