[0041] Self-locking units are provided between the electric inner shaft 108 and the liquid inner shaft 109 and the corresponding supporting circular blocks 122. Square sliders 131 are slidably installed in a circular array on the supporting circular blocks 122. Reset springs 129 are provided between the surface of the square slider 131 closest to the axis of the rotor 101 and the supporting circular blocks 122. Fixed sliders 118 are fixedly provided on the sides of the square sliders 131. Four sliding grooves cooperating with the fixed sliders 118 are provided in a circular array at the ends of the electric inner shaft 108 and the liquid inner shaft 109 closest to the corresponding supporting circular blocks 122. The self-locking unit includes a conical push block 113 slidably installed on the rotor 101. The conical push blocks 113 form a spline sliding fit with the rotor 101.

The conical push blocks 113 are used to push the corresponding four trapezoidal push blocks 130 to move synchronously.

[0042] When the electric inner shaft 108 and the liquid inner shaft 109 are both fixedly mounted on the rotor 101, the conical push blocks 113 are both located at the positions closest to the corresponding supporting round blocks 122. At this time, under the action of the conical surface on the conical push blocks 113, the trapezoidal push blocks 130 are both located at the positions farthest from the axis of the rotor 101, that is, the fixed sliders 118 and the square sliders 131 are both located at the positions farthest from the axis of the rotor 101. At this time, the reset springs 129 are both in a stretched state, and the four fixed sliders 118 corresponding to the electric inner shaft 108 are respectively engaged with the four slide grooves on the electric inner shaft 108, and the four fixed sliders 118 corresponding to the liquid inner shaft 109 are respectively engaged with the four slide grooves on the liquid inner shaft 109, that is, under the action of the fixed sliders 118, the electric inner shaft 108 and the liquid inner shaft 109 cannot move relative to the rotor 101, that is, the electric inner shaft 108 and the liquid inner shaft 109 are both fixed to the rotor 101.

The self-locking shaft 126 and the corresponding external thread 125 constitute a spiral pair. The external thread 125 and the self-locking shaft 126 are used to move the corresponding conical push block 113 relative to the rotor 101. Three self-locking slide bars 128 are fixed in a circular array on the conical push block 113. An inner ratchet ring 114 is movably provided on the conical push block 113. The inner ratchet ring 114 is slidably matched with the three self-locking slide bars 128 on the corresponding conical push block 113. A self-locking spring 127 is provided between the inner ratchet ring 114 and the corresponding conical push block 113. An outer ratchet ring 124 is fixedly provided on the self-locking shaft 126. When the outer ratchet ring 124 is engaged with the corresponding inner ratchet ring 114, a ratchet mechanism is formed.

[0044] In the initial position, the self-locking spring 127 between the inner ratchet ring 114 and the conical push block 113 is not compressed. At this time, the inner ratchet ring 114 is engaged with the corresponding outer ratchet ring 124 to form a ratchet mechanism. Under the action of the inner ratchet ring 114 and the outer ratchet ring 124, the self-locking shaft 126 cannot move in the direction away from the corresponding supporting round block 122, thereby achieving the locking of the position of the self-locking shaft 126 and then achieving the locking of the position of the conical push block 113.

[0045] A hexagonal ring plate 112 is fixedly provided on the end face of the self-locking shaft 126 that is farthest from the corresponding supporting round block 122. The hexagonal ring plate 112 is used to facilitate driving the self-locking shaft 126 to rotate. The rotation of the self-locking shaft 126 is facilitated by engaging a wrench that cooperates with the hexagonal ring plate 112 with the hexagonal ring plate 112.

[0046] A semicircular cover plate 102 is symmetrically arranged between the liquid shell 106 and the electric shell 107. Limiting short columns 104 are symmetrically fixedly arranged on both sides of the liquid shell 106 and the electric shell 107. Through holes cooperating with the limiting short columns 104 are arranged on both sides of the semicircular cover plate 102. Bolts 103 are symmetrically arranged between the two semicircular cover plates 102, and the bolts 103 are used to achieve the fixation between the two semicircular cover plates 102.

[0047] In the initial position, the through holes on both sides of the semicircular cover plate 102 are respectively engaged with the limiting short columns 104 on the liquid shell 106 and the electric shell 107, and then the bolts 103 fix the two semicircular cover plates 102. At this time, the self-locking unit between the electric inner shaft 108 and the rotor 101 and the self-locking unit between the liquid inner shaft 109 and the rotor 101 are both located in the area between the two semicircular cover plates 102, that is, the protection of the self-locking unit components is achieved under the action of the two semicircular cover plates 102.

[0048] When the electric slip ring or liquid slip ring is damaged and needs to be repaired, first remove the two bolts 103 between the two semicircular cover plates 102, then remove the semicircular cover plate 102 from between the liquid shell 106 and the electric shell 107, and then push the inner ratchet ring 114 corresponding to the electric slip ring or liquid slip ring to be repaired to move relative to the corresponding outer ratchet ring 124, so that the inner ratchet ring 114 is disengaged from the corresponding outer ratchet ring 124, and the self-locking spring 127 between the inner ratchet ring 114 and the corresponding conical push block 113 is compressed, and then the wrench corresponding to the hexagonal ring plate 112 is engaged with the hexagonal ring plate 112, and the wrench is turned to rotate the hexagonal ring plate 112, thereby making The self-locking rotating shaft 126 corresponding to the hexagonal ring plate 112 moves in the direction away from the corresponding supporting circular block 122, and the conical push block 113 corresponding to the hexagonal ring plate 112 moves synchronously, and the conical push block 113 releases the support for the trapezoidal push block 130. Under the action of the reset spring 129, the fixed slider 118, the trapezoidal push block 130, and the square slider 131 all move in the direction close to the axis of the rotor 101, so that the fixed slider 118 is disengaged from the sliding groove on the electric inner shaft 108 or the liquid inner shaft 109, that is, the required electric inner shaft 108 or the liquid inner shaft 109 is fixed, and the required electric inner shaft 108 or the liquid inner shaft 109 can be removed from the rotor 101.

[0049] The invention also discloses a method for transmitting multiple media such as photoelectric liquid, etc., which is characterized by comprising the following steps.

[0050] Step 1: The rotor 101 is fixedly mounted on the central axis of the rotating component, and then the liquid housing 106 and the electric housing 107 are fixedly mounted on the stationary component.

[0051] Step 2: The rotating part of the optical fiber rotary joint 111 is fixedly connected to the rotor 101, and the stationary part of the optical fiber rotary joint 111 is also fixedly installed on the stationary part.

[0052] Step three: the rotor 101 rotates, and the rotating part of the optical fiber rotary joint 111 rotates relative to the stationary part of the optical fiber rotary joint 111 , thereby realizing the transmission of optical signals between the optical fiber rotary joint 111 and the optical fiber 116 .

[0053] Step 4: The rotor 101 rotates, that is, the liquid inner shaft 109 rotates relative to the liquid outer shell 106, so that the required liquid outlet 115 is connected with the required liquid inlet 110, that is, the communication of the required liquid medium delivery channel is achieved, thereby achieving the delivery of the liquid medium.

[0054] Step 5: The rotor 101 rotates, so that the inner shaft 108 rotates relative to the outer shell 107, and then the contact ring 120 rotates relative to the brush holder 121, so that electrical connection is achieved under the action of the brushes on the brush holder 121 and the contact ring 120, and then the wiring port 1 105 and the wiring port 2 119 can realize the transmission of electrical signals.
