Technical Field

[0002] Once a solid structure is placed in water, it will be affected by biological attachment. The growth of a large number of biological attachments will inevitably affect the detection accuracy of scientific detection sensors. In order to ensure the continuous stability of the sensor's detection accuracy, it is necessary to inhibit the growth of biological attachments in key areas, but at the same time, this prevention and control measure should not affect the accuracy of the detection data. The existing underwater membrane permeability sensor anti-biological attachment device can generally only work according to the pre-set protection strength, but when the set value does not match the actual environment, the anti-biological attachment effect is very poor, so there is a need for an anti-biological device that can adaptively adjust the protection strength according to the environment.
