Example Embodiment

[0013] Example 1

[0014] Such as figure 1 As shown, figure 1 Schematic diagram of the assembly of the anti-biological attachment device for the underwater membrane permeation sensor.

[0015] It includes a watertight connector 1, a watertight lamp cover 2, a UV ray tube 3, a locking cover 4, a transparent sheet 5, a copper mesh 6 and a protected sensor 7.

[0016] The watertight connector 1 is a commercial product. The main structure is formed by connecting the threaded column section and the large cylindrical section. The large cylindrical end surface is equipped with two power receiving terminals, and the end surface where the large cylindrical and threaded column connects is equipped with an O-ring. After the O-ring is installed in the groove, the small end surface of the watertight lampshade 2 forms a sealing fit. The end surface of the threaded cylinder of the watertight connector 1 is led out by two electric wires for connecting with both ends of the UV ray tube 3.

Abstract

The invention relates to an anti-bio-adhesion device for an underwater membrane permeation sensor. The anti-bio-adhesion device for an underwater membrane permeation sensor includes a watertight connector, a watertight lampshade, a UV ray lamp tube, a locking cover, a light-transmitting sheet, a copper mesh and a quilt Protect the sensor, the watertight lampshade is a bowl-shaped structure, the center of the bottom of the bowl forms a thread pair with the watertight connector, the small end surface of the bowl bottom fits with the sealing end face of the watertight connector to form an axial sealing fit, and the locking cover forms a thread pair with the watertight lampshade ;The UV ray lamp is located in the inner space of the watertight lampshade, the protected sensor extends into one side of the copper mesh, and the large end surface of the bowl mouth of the watertight lampshade extends into the other side of the copper mesh, and the protected sensor, copper mesh and watertight lampshade are coaxially arranged; the lock The diameter of the circular hole in the middle of the tight cover is slightly larger than the diameter of the outer cylindrical surface of the light-transmitting sheet, which is used to limit the displacement of the light-transmitting sheet in the radial direction. The invention can be used for the inhibition of bio-adhesion of the membrane permeable sensor, prevents the drift of observation data and increases the accuracy of corresponding observation while not affecting the detection of this type of sensor.

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...
