The device is widely applied to all electromechanical systems which are required to provide an unlimited, continuous or intermittent rotating mechanism and provide multi-channel rotating power, data and signals. The system structure is greatly simplified, and sprain, winding disorder or incapability of rotating motion caused by the wire in the rotating process are avoided.

The current conductive slip ring technology has the following problems: the quality requirement of parts for manufacturing the slip ring is high, the process is complex, the cost is high, and the use environment is harsh; the conductive slip ring generally adopts metals such as an electric brush or mercury and the like as an electric brush component, and when various power supplies and signals are transmitted, the conductive slip ring is influenced by factors such as electric brush abrasion, contact resistance, pressure, rotating speed, assembly precision and the like, so that the service life and the quality of the transmitted signals are often influenced, and even some high-frequency signals are difficult to transmit; for some large-scale relative rotating mechanisms, high-load and high-frequency signal transmission, the 'slip ring' structure is difficult to realize, or the cost is very high, and the manufacturing is difficult; and the conduction cannot be carried out on non-electric signals or energy sources, such as: gas, liquid, pressure, oil pressure, etc.; the conductive slip ring generally needs to occupy a central position of the device, which makes other components in the device that need to be placed in the central position impossible.

The utility model provides a rotate UNICOM device that this application embodiment provided is a mechanical mechanism for rotatory transmission pipeline (line) of transmission medium, and not medium itself, so the quality of transmission only receives the factor influence of self of transmission pipeline (line), so can transmit more mediums of UNICOM, like the transmission: power supply, weak current, electromagnetic signal, optical signal, air pressure, water pressure, oil pressure and other different media. Therefore, compared with the conductive slip ring, the rotary communication device is relatively simple to manufacture, has low requirements on materials, relatively easily-obtained materials and processes, relatively low cost, can meet the rotary communication requirements of a larger relatively-rotating mechanism, and can be suitable for conducting other media except light, electricity and signals, such as: liquid, pressure, gas and other mediums suitable for conductor, optical fiber and flexible pipeline transportation.
