    • An underwater plow can include a depressor cam and a chute cam that are pivotably attached to a blade portion. The blade portion can be formed with a trough and the depressor cam can be biased in the trough. The chute cam can be formed with a groove having a minimum thickness at its attached end and an increasing taper to a maximum thickness at its distal end. A sensor passing through the plow contacts the edge of the depressor cam, causing depressor cam rotation away from the trough. The sensor passes the depressor cam and pushes against the chute cam, which causes the chute cam to contra-rotate relative to the depressor cam until the sensor passes through the chute arm at is maximum thickness. Once the sensor passes through, the cams contra-rotate back to their respective biased positions.
    • 水下犁可以包括可枢转地附接到叶片部分的压下凸轮和滑槽凸轮。 叶片部分可以形成有槽,并且压力凸轮可以偏置在槽中。 滑槽凸轮可以在其附接端形成具有最小厚度的凹槽,并且在其远端处形成增加的锥度至最大厚度。 穿过犁的传感器接触压力凸轮的边缘,使压力凸轮转动远离槽。 传感器通过压力凸轮并推动斜槽凸轮,这导致滑槽凸轮相对于压力凸轮相反转动,直到传感器以最大厚度通过滑槽臂。 一旦传感器通过,凸轮反向旋转回其各自的偏置位置。

    • An autonomous underwater plow can include a frame, a plow assembly and a propulsion assembly. The plow assembly is fixed to the one end of the frame, while the propulsion assembly is pivotably attached to the other end. The propulsion assembly includes thrusters that are rigidly coupled to a float, and that provide a propulsion force perpendicular to the float buoyancy force. The plow sinks when placed in the water, but the float provides sufficient buoyancy so that the float end floats while the plow end is in contact with the ocean floor. This establishes a rake angle of between the frame and ocean floor. The plow requires less propulsion force for motion because part of the plow is floating, and requires less force to overcome obstacles on the ocean floor because the thrusters provides a constant horizontal propulsion force while the frame tilts to overcome the obstacle.
    • 自主的水下犁可以包括框架,犁组件和推进组件。 犁组件固定到框架的一端,而推进组件可枢转地附接到另一端。 推进组件包括刚性地联接到浮子的推进器,并且提供垂直于浮子浮力的推进力。 当放置在水中时,犁槽下沉,但是浮子提供足够的浮力,使得浮子端在犁端与海底接触时浮动。 这确定了框架和海底之间的前角。 由于犁的一部分是浮动的,所以犁需要更少的推进力,并且需要更少的力来克服海底上的障碍物,因为推进器在框架倾斜以克服障碍物时提供恒定的水平推进力。

    • An underwater plow includes a plow assembly that is attached to a frame. The plow assembly includes a blade portion, which defines a blade trough, and a sensor chute portion. The blade portion extends downwardly below a plane that is coincident with a longitudinal axis defined by the frame, while the chute portion extends upwardly above the same plane. A depressor arm is pivotably attached to the blade portion and biased to be in contact with the trough. The depressor arm has a groove that is sized to allow the cable, but not the sensors, to pass through the groove while the depressor arm is in contact with the trough. With this configuration, an array cable passes downward through the blade portion of the plow assembly and becomes buried in the ocean floor. Array sensors, however, are routed upward and pass through the chute portion of the plow assembly.
    • 水下犁包括附接到框架的犁组件。 犁组件包括限定叶片槽的叶片部分和传感器滑槽部分。 刀片部分向下延伸到与由框架限定的纵向轴线重合的平面上,而斜槽部分在相同的平面上方向上延伸。 压力臂可枢转地连接到叶片部分并被偏压以与槽接触。 压降臂具有凹槽,其尺寸允许电缆(而不是传感器)在压降臂与槽接触的同时通过凹槽。 利用这种构造,阵列电缆向下通过犁组件的叶片部分并且被埋在海底。 然而,阵列传感器被向上引导并穿过犁组件的斜槽部分。
