[0023] When the rotor body 2 is sleeved on one end side of the stator body 1 through the rotating groove 13 , the annular spring 22 is in a compressed state and the side surface of the active sealing ring 23 is tightly fitted with the end side surface of the stator body 1 .

[0024] like Figure 1-4As shown, the rotor body 2 is rotatably sleeved on the end face of the stator body 1 through the rotating groove 13. At this time, the inner ring surface of the sealing ring 20 arranged in the installation sealing groove is in contact with the side face of the stator body 1. An active sealing groove 21 is opened on the inner ring surface of the sealing ring 20, and an annular spring 22 is provided on the bottom wall of the active sealing groove 21 in a compressed state. Under the elastic force of the annular spring 22, the active sealing ring 23 located at the opening of the active sealing groove 21 is tightly fitted with the side face of the end face of the stator body 1, thereby ensuring the sealing between the rotor body 2 and the stator body 1, improving the sealing of the optoelectronic hybrid slip ring body, and ensuring the normal use of the optoelectronic hybrid slip ring body underwater.

[0025] Two auxiliary sealing grooves 18 are formed on the wall of the rotating groove 13 symmetrically with respect to the opening of the installation sealing groove. The sealing mechanism further includes an auxiliary sealing ring 19 disposed in the auxiliary sealing groove 18 .

[0031] The sealing disk 5 is provided through the end surface of the sealing block 3 away from the rotor body 2 and is provided with a sealing hole 4 which is connected to the first through hole 14 .

[0032] like Figure 2-3As shown, the sealing disk 5 is controlled to move toward the first through hole 14, and then a sealing filler is injected into the installation sealing groove through the sealing hole 4 and the first through hole 14. When the rotor body 2 and the stator body 1 rotate between them, the sealing filler fills the gap between the active sealing ring 23 and the auxiliary sealing ring 19 and the side surface of the stator body 1, thereby ensuring the sealing performance of the rotation between the stator body 1 and the rotor body 2, improving the sealing performance of the optoelectronic hybrid slip ring body, and ensuring the normal use of the optoelectronic hybrid slip ring body underwater.
