Description

Technical Field

[0001] The utility model relates to the technical field of water quality sensor cleaning, in particular to a water quality monitoring sensor cleaning and maintenance device. Background Art

[0002] The contacts of water quality sensors are generally cylindrical. When used in water bodies with poor water quality, a layer of attachment will form on the contact surface of the water quality sensor, corroding the contacts and affecting the operation of the sensor. Therefore, the contacts of the sensor need to be cleaned to ensure that the sensor can work normally for a long time and ensure the monitoring effect.

[0003] The existing Chinese utility model patent with reference publication number CN210497462U discloses a water quality sensor cleaning device, comprising a housing, a fixed door, a hinge, and a fixing device provided on the top of the housing, the fixed door being movably connected to the top of the housing via the hinge, a filter provided on the bottom of the housing, an observation window and a water-passing window provided on the outer side of the housing from top to bottom, and an infrared receiver, an ultrasonic transmitter, and a spray device provided on the inner side of the housing from top to bottom. The water quality sensor cleaning device, through the provision of an infrared receiver, an ultrasonic transmitter, and a spray device, activates the ultrasonic transmitter to emit ultrasonic waves for sonic cleaning upon receiving a command, activates a small motor to pass water through the spray head for water cleaning, and, through the provision of a buoy, allows the entire water quality sensor to float steadily on the water surface. Water in different areas of the water surface affects the degree of submergence. If the bottom of the water contains too many impurities, it will damage the water quality sensor, thus avoiding unnecessary economic losses.

[0004] Existing cleaning equipment generally removes stains attached to the sensor surface by brushing. This method may cause wear on the sensor contact surface during the cleaning process, affecting the service life of the sensor. At the same time, the existing cleaning device requires a certain relative displacement between the cleaning structure and the sensor to ensure the cleaning effect. The transmission structure is complex and maintenance is very inconvenient. Utility Model Content
