Description

Technical Field

[0001] The utility model belongs to the technical field of photoelectric liquid slip rings, in particular to an integrated photoelectric liquid slip ring. Background Art

[0002] The rotational torque transmission of an integrated optoelectronic slip ring rotor is generally a chain-type transmission method, that is, the liquid distributor component transmits the torque to the electric slip ring component, which then transmits the torque to the liquid slip ring component, and finally the liquid slip ring component transmits the torque to the smooth ring component. In this type of structure, the liquid distributor and the liquid slip ring are connected by a flexible hose, which is complex. At the same time, the cumulative dimensional tolerances during the assembly process are large, which is not conducive to the precise design of the slip ring. The electric slip ring component, smooth ring component, and liquid slip ring component of existing integrated optoelectronic slip rings are all fixed to the housing or end cap. This results in the smooth ring component being located at the bottom of the liquid slip ring. In extreme cases, leakage and failure of the liquid slip ring will affect the normal operation of the smooth ring component.

[0003] Patent document CN220510428U discloses a photovoltaic-fluid combination hinge comprising a combined slip ring and a heat sink ring. The combined slip ring comprises a stator portion and a rotor portion disposed coaxially within the stator portion. The heat sink ring comprises an outer ring and an inner ring, the stator portion being fixedly connected to the outer ring. The inner sidewall of the outer ring is formed with a first annular groove and a second annular groove. The inner ring is coaxially disposed with the outer ring, the rotor portion is disposed within the inner ring, the inner sidewall of the inner ring being in contact with the side surface of the rotor portion, and a sandwich cavity is formed within the inner ring. This photovoltaic-fluid combination hinge utilizes a heat sink ring with liquid circulation function disposed externally to the photovoltaic combination slip ring, allowing the heat generated during operation to be promptly absorbed by the heat sink ring. However, the patent does not include a drainage component to prevent liquid leakage from the heat sink ring from affecting the operation of the photovoltaic slip ring. Utility Model Content
