摘要： A housing and telescoping arm are supported by a shaft pivot pivotally mounted in the ground. The telescoping arm includes a rotating rod actuator journalled for rotation in a bearing mounted atop the shaft. The rod includes a threaded portion extending longitudinally from the shaft to the gate. A traveling tubular member is mounted concentrically with the rod and includes a block having a threaded bore for receiving the threads of the rod. The arm is connected to the gate through a pinned connection between one end of the traveling member and a lower rail of the gate. Relative rotation between the rod an the traveling member is prevented by the pinned connection. As a result, the traveling member extends outwardly and retracts inwardly in response to the counter-clockwise and clockwise rotation respectively of the rod. A motor and transmission for driving the rod in rotation are mounted in the housing along with a motor control circuit. The motor control circuit receives a start switch signal and shuts the motor off after the gate has swung to either the open or closed positions by receiving a stop signal from a limit switch. The direction of the motor is reversed each time a signal is received from a limit switch so that the gate is alternately opened and closed by the apparatus. The apparatus can be used in areas not supplied with commercial power, since it is battery powered. A solar cell panel recharges the battery so that a completely self-sufficient operation is provided.

摘要翻译： 壳体和伸缩臂由枢转地安装在地面中的轴枢轴支撑。 伸缩臂包括旋转杆致动器，其轴颈安装在安装在轴顶上的轴承中旋转。 杆包括从轴纵向延伸到门的螺纹部分。 行进的管状构件与杆同心地安装并且包括具有用于容纳杆的螺纹的螺纹孔的块。 臂通过行进构件的一端和门的下导轨之间的钉扎连接连接到门。 杆与移动部件之间的相对旋转通过固定连接来防止。 结果，行进构件向外延伸并响应于杆的逆时针和顺时针旋转向内缩回。 用于驱动杆旋转的电动机和变速器与电动机控制电路一起安装在壳体中。 电机控制电路接收启动开关信号，并通过从限位开关接收到停止信号，在门已经打开或关闭位置之后关闭电机。 每次从限位开关接收到信号时，电机的方向都会相反，从而使门被交替地打开和关闭。 该设备可用于没有商业电源的区域，因为它是电池供电的。 太阳能电池板为电池充电，从而提供完全自给自足的操作。
