Abstract: A friction and wear testing platform capable of simulating high-pressure, silt-containing and turbid submarine environment, including a tank, a loading device, a partition plate, a partition cylinder, a top sealing sleeve, a bottom sealing sleeve, a rotating shaft, an inner magnetic cylinder, an outer magnetic cylinder and a centering table. The partition plate and the partition cylinder divide an inner chamber of the tank into a test chamber and a pressure compensation chamber. The rotating shaft penetrates the pressure compensation chamber; two ends of the rotating shaft are sealed by the top and bottom sealing sleeves, respectively, as well as sealing bearings and rings therein. The loading device drives the rotating shaft to rotate, and the rotating shaft drives the inner magnetic cylinder to rotate. The centering table is driven through the magnetic coupling between the inner and outer magnetic cylinders to install a test piece.

Abstract: A horizontal drilling machine with an in-situ detection device, including a support frame, an armored cable, a steel pipe-straightening mechanism, a steel pipe-feeding mechanism, a motor, a power head, a drill pipe, a rotating chuck, a damper, a non-core drilling tool, the in-situ detection device, a fishing device and a thrust cylinder. The steel pipe-straightening mechanism, the steel pipe-feeding mechanism, the rotating chuck and the damper are sequentially fixed on the support frame from left to right. One end of the thrust cylinder is hinged with the support frame, and the other end is connected to the power head. The active drill pipe of the power head is connected to the drill pipe. An end of the armored cable is connected to the fishing device in the drill pipe, and the fishing head of the fishing device is connected to the spearhead of the non-core drilling tool.

Abstract: A support device for the rotation of a high-capacity and compact drill pipe storage unit of a seabed drilling rig in a lying state, including: a rack, a plurality of curved support frames, a plurality of lateral drill pipe stoppers and a plurality of annular fences. The curved support frames are provided parallelly and coaxially on a slideway of the rack. A separating plate is provided on each of the curved support frames. A curved support surface of each of the curved support frames is in contact with a circular edge surface of the corresponding separating plate. The annular fences are mounted on the rack. Each of the annular fences is provided with a first gap and a second gap. The first gap is provided corresponding to the lateral drill pipe stopper. The second gap is configured to allow the drill pipes enter and exit the drill pipe storage unit.
