Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine drilling platform technology, specifically to a marine drilling platform pipe string docking mechanism. Background Technology
[0002] Offshore drilling platform tubing refers to various tubing equipment used in offshore drilling processes. It is mainly used to support and protect drilling operations, ensuring the smooth progress of the drilling process. Tubing is usually made of steel and consists of many small tubing sections used to transport drill pipe fluid and gas, and to support and protect the drill pipe.
[0003] In response, Chinese patent application number CN220082383U discloses a pipe docking mechanism. In this application, a junction box is fixedly installed on the upper surface of the docking sleeve, and a transmission wire is fixedly installed on the lower surface of the junction box. The other end of the transmission wire is connected to a drive motor. A compression channel is opened in the middle of the interior of the docking sleeve, and a booster impeller is connected and installed in the middle of the compression channel. The docking sleeve provides installation positions for the pipes at both ends. The junction box is used to exchange connections between external cables and the transmission wire inside the docking sleeve. The transmission wire transmits externally supplied power to the drive motor, which is used as the power source for booster drive. The compression channel provides a passage for water to enter and exit the interior of the docking sleeve. The booster impeller can pressurize the passing water flow to meet the transportation needs of long-distance water pipes. By setting up a component for pressurizing the pipes inside the mechanism, the pressure of the liquid inside the long-distance transportation pipe is increased, thereby enhancing the transportation efficiency of the liquid inside the pipe.
[0004] However, existing offshore drilling platform pipe string docking mechanisms only use simple threaded sleeves for docking, which is necessary because offshore drilling platform pipe strings need to be docked. The pressure inside the pipe string is relatively high, and after long-term use, the existing docking may shift or the pipe string may fall off, thus affecting the normal operation of the equipment to some extent.
