摘要： An actuator device includes a shape memory alloy (SMA) device comprising an two way SMA element transformable from a deformed shape to a pre-deformed shape at a temperature of the SMA element that is above a transition temperature of the SMA element. The actuator device further includes a valve having an opening therethrough. The valve is moveable between an open position and a closed position. The actuator device also includes a biasing element. The valve is positioned between the SMA device and the biasing element. The SMA element is substantially cone-shaped, and a wall of the SMA element is slanted down at an angle that is between approximately 40 degrees and approximately 90 degrees relative to a vertical axis extending through the wall.

摘要： An apparatus and method is disclosed for generating power from the energy of fluid flow in a conduit, such as a pipeline or production tubing of a wellbore. A fan may be comprised of a plurality of blades positioned circumferentially around a central cavity. The blades may be adapted for receiving fluid flow and transmitting energy of fluid flow to rotate the fan. The fan may be configured for generating rotational movement of a magnet relative to an electromagnetic winding to produce electrical energy. The central cavity may be adapted for receiving objects such as wellbore intervention tools or other devices for insertion into the central cavity.
摘要翻译：公开了一种用于从导管（例如管道或井筒的生产管道）中的流体流的能量产生功率的装置和方法。风扇可以由围绕中心腔周向定位的多个叶片构成。叶片可以适于接收流体流动并传递流体流动的能量以旋转风扇。风扇可以被配置为产生磁体相对于电磁绕组的旋转运动以产生电能。中心腔可以适于接收诸如井眼介入工具或用于插入中心腔的其它装置的物体。
