In the present embodiment, the ascending linear motion of the lead screw 3 can drive the internal meshing ratchet mechanism 8 inner wheel of the pawl into the internal mesh ratcheting mechanism 8 outer wheel cogging, realizing one-way power transmission.

[0024] In the present embodiment, when the self-cleaning anti-attachment device is working normally, the floating bladder 7 is exposed to the sea surface by its own buoyancy. With the natural floating of the sea surface, the floating bladder 7 follows the floating on the sea surface, but due to inertia, other components other than the floating bladder 7 remain in the original position, so the floating bladder 7 upward linear motion is straightened flexible connector 6. And then the flexible connector 6 transmits this linear motion to the screw 3 to form a rotary motion. At this time, the internal meshing ratchet mechanism 8 transmits the rotation movement of the screw 3 to the rotating ring 11, the rotating ring 11 conducts a one-way rotation around the wire netting ball 5 or even several laps, and finally the brush 12 is provided on the inner wall of the rotating ring 11 to sweep away the attachments on the surface of the wire netting ball 5. On the contrary, the sea surface changes with the gravity. Due to the inertia, the floating bladder 7 and other components will sink together, leaving the flexible connector 6 be slightly relaxed, plus the inner mesh ratchet mechanism 8 one-way motion design protection, when the inner wheel rotates in the opposite direction, the inner wheel of the ratchet on the back of the ratchet tooth slid over, the outer wheel is stationary can not transmit power, to avoid turning ring 11 in a small range of back and forth, the cleaning of the wire netting ball 5 is not in place. A self-cleaning and anti-adhesion device disclosed in the present embodiment uses the buoyancy of the natural wave energy to drive the rotating ring 11 unidirectional rotation to clean the outer wall of the wire netting ball 5, without other energy, the cleaning process is efficient and reliable, to ensure that the sensor (such as the temperature salt depth probe) installed inside the wire netting ball 5 is not blocked, and the observation accuracy of the instrument for a long time span is improved.
