Abstract

The invention discloses a signal transmission structure of a drill pipe. The signal transmission structure comprises a three-ridge drill pipe body, a seal signal wire groove and a seal signal wire; the seal signal wire is fixedly arranged inside the three-ridge drill pipe body through the seal signal wire groove; signals are transmitted to equipment outside a drill hole through the seal signal wire. The signal transmission structure has no influence on the drilling progress, easy and convenient to use in whole, accurate and rapid in data transmission, and capable of being suitable for drilling technologies using the three-ridge drill pipe body, and has a wide market application prospect.

Description

technical field [0001] The invention relates to the field of coal mine equipment, in particular to a data transmission structure and method of a triangular drill pipe used in coal mines. Background technique [0002] With the development of comprehensive mechanized coal mining technology in coal mines in my country, the requirements for mine safety production on construction equipment and technologies such as underground exploration holes, water discharge holes, and gas drainage holes are also continuously increasing. At the same time, it is necessary to be able to accurately measure the drilling trajectory and transmit the data measured at the drill bit end to the orifice equipment, which has always been an urgent problem to be solved in coal mines. Therefore, it is necessary to provide a data transmission method for triangular drill pipe. Contents of the invention [0003] In view of this, one of the purposes of the present invention is to provide a signal transmission s...
