Biological adhesion-preventing device for underwater membrane permeation sensor

Abstract

The invention relates to a biological adhesion-preventing device for an underwater membrane permeation sensor. The biological adhesion-preventing device comprises a watertight connector, a watertight lampshade, a UV ray lamp tube, a locking cover, a light-transmission piece, a copper net and a protected sensor, wherein the watertight lampshade is a bowl-shaped structure; a center of a bowl bottom and the watertight connector are subjected to screw thread pair fit; a small end surface of the bowl bottom is bonded to a sealing end surface of the watertight connector to form axial sealing fit; the locking cover and the watertight lampshade are subjected to the screw thread pair fit; the UV ray lamp tube is located at an internal space of the watertight lampshade; the protected sensor stretches into one side of the copper net; a large end surface of a bowel mouth of the watertight lampshade stretches into the other side of the copper net; the protected sensor, the copper net and the watertight lampshade are arranged coaxially; a pore size of a circular hole in the middle of the locking cover is slightly greater than a diameter of an external cylindrical surface of the light-transmission piece and is used for limiting radial displacement of the light-transmission piece. The biological adhesion-preventing device provided by the invention can be used for inhibiting biological adhesion of a membrane permeation sensor, and can prevent observed data from drifting and improve corresponding observation accuracy without affecting detection of such sensors.

Description

technical field [0001] The invention belongs to the technical field of marine engineering and relates to an underwater membrane permeation sensor anti-biological adhesion device. Background technique [0002] Once a solid structure is placed in water, it will be affected by bio-attachment, and the growth of a large number of bio-attachments will inevitably affect the detection accuracy of scientific detection sensors. In order to ensure the continuous stability of the detection accuracy of the sensor, it is necessary to inhibit the growth of biological deposits in key parts, but at the same time, this prevention method cannot affect the accuracy of the detection data. Most of the traditional methods are passive methods such as unsystematic use of copper plates and copper mesh. The defect of this method is that the ability to inhibit bio-adhesion cannot be controlled, and its anti-bio-adhesion effect has great uncertainty. In addition, the method of anti-fouling by the relea...

In order to ensure the continuous stability of the detection accuracy of the sensor, it is necessary to inhibit the growth of biological attachments in key parts, but at the same time, this prevention method cannot affect the accuracy of detection data

Most of the traditional methods are unsystematic use of passive methods such as copper plates and copper mesh. The defect of this method is that the ability to inhibit bio-adhesion cannot be controlled, and its anti-bio-adhesion effect has great uncertainty.

In addition, the method of anti-bio-fouling through the principle of release of bactericide may cause detection interference to the membrane osmotic pump sensor
