  • Patent number: 10605023
    Abstract: The present disclosure provides an automatic push corer system including a base, a power group, a Geneva transmission group, an intermittent transmission group, a vertical coring transmission group, a clamp group and a coring group. The power group is used to drive the Geneva transmission group. The Geneva transmission group is configured to perform a first intermittent rotary motion. The intermittent transmission group is configured to perform a second intermittent rotary motion. The vertical coring transmission group is configured to cooperate with the second intermittent rotary motion to perform a third intermittent rotary motion. The clamp group is configured to cooperate with the third intermittent rotary motion to perform a lifting reciprocation. The coring group is configured to cooperate with the first intermittent rotary motion and the lifting reciprocation to respectively complete a coring operation and a tubing replacing operation.

  • Publication number: 20150092519
    Abstract: A sphere-inscribed wheel-driven mobile platform for universal orientation includes an outer shell unit, a seismometer module, a level sensing module, a movable unit, and a bearing unit. The outer shell unit includes an inner spherical surface defining an accommodating chamber. The seismometer module is disposed in the accommodating chamber, and defines a central axis. The movable unit is mounted to the seismometer module, and includes two rotating wheel units. The bearing unit is mounted to the seismometer module, and includes a plurality of bearing members disposed around the central axis. The seismometer module and the inner spherical surface are spaced by the movable unit and the bearing unit. The seismometer module is rotatable about the central axis and a rotating axis perpendicular to the central axis.
