Abstract

This invention relates to the field of well workover equipment technology, specifically a blowout prevention device. It includes a vertical shaft, a horizontal arm, a horizontal arm lifting drive mechanism, a plug assembly, and a plug switch drive mechanism. The vertical shaft has a horizontal arm that can rotate around the shaft and move up and down. The plug assembly is rotatably mounted on the horizontal arm. The horizontal arm lifting drive mechanism is connected to the horizontal arm to drive its up and down movement. The plug switch drive mechanism is connected to the plug assembly to drive it to open or close. This invention has a reasonable structure and ingenious design. Through the design of this application, during the installation of the plug assembly, it is no longer necessary for operators to manually carry the plug assembly to the wellhead. This not only greatly reduces the difficulty of plug assembly installation but also avoids injuries to operators from blowout-induced liquids and gases during the handling and placement of the plug assembly.
