The invention relates to an oil-immersed contact type transmission slip ring which comprises a slip ring stator framework of an annular structure and a slip ring rotor framework, an annular polyimideframework is fixedly arranged on the outer wall of the slip ring rotor framework, a plurality of annular copper-zinc alloy slideways are installed on the surface of the polyimide framework at intervals, the slideways are electrically connected with a single-core copper wire, and the single-core copper wire is electrically connected to a micro connector; a plurality of hollowed-out grooves are evenly distributed in the circumferential direction of the slip ring stator framework, wiring boards are fixedly installed in the hollowed-out grooves, the faces, facing the inner side of the slip ring stator framework, of the wiring boards are electrically connected with electric brushes through wires, the wiring boards in the adjacent hollowed-out grooves are connected in series through wires, the wires are finally electrically connected with a D-Sub connector, and the D-Sub connector is installed on a D-Sub connector insulating base. The slip ring stator framework is sleeved on the outer side of the slip ring rotor framework, and when the slip ring rotor framework rotates, the electric brushes slide along the slideways. The power supply and signal transmission functions of an underground instrument can be met, and the transmission slip ring is suitable for the severe environment of underground high rotating speed and strong vibration.
Description
technical field [0001] The invention belongs to the technical field of petroleum drilling equipment, and in particular relates to an oil-immersed contact transmission slip ring used for an intelligent drilling tool. Background technique [0002] In the oil drilling industry, many intelligent drilling tools need to transmit power and signals in a rotating state. Due to the harsh downhole environment, high speed, strong vibration, etc., it is easy to cause brushes to wear, track, insulation to fail, and single-core wires Easy to loose and other disadvantages. [0003] Therefore, based on these problems, it is of great practical significance to provide an oil-immersed contact transmission slip ring for intelligent drilling tools that can meet the power supply and signal transmission functions of downhole instruments and adapt to the harsh environment of high speed and strong vibration downhole. Contents of the invention [0004] The purpose of the present invention is to ove...
