    • A pressurized underground enclosure includes a battery venting system having a battery within a battery box in a sealed enclosure. A first pipe is fluidly connected to the battery box and an ambient atmosphere and includes a vacuum generator for reducing a pressure in the battery box. A second pipe is fluidly connected to the battery box and the ambient atmosphere and includes a one-way valve permitting airflow to the battery box and precluding airflow from the battery box to the ambient atmosphere. The enclosure includes a scissors lift including scissor linkage units having arms pivotally connected at terminal ends and at central positions. The scissor linkage units are moveable from a retracted to an extended position by pneumatic cylinders. The internal pressurization of the enclosure is selectively released and locking mechanisms are retracted before a rack of the scissors lift is extended through an opening of the enclosure.
    • 加压地下围栏包括一个电池排放系统,该电池排放系统在密封的外壳内具有电池盒内的电池。 第一管流体地连接到电池盒和环境大气,并且包括用于减小电池盒中的压力的​​真空发生器。 第二管道流体地连接到电池箱和环境大气,并且包括允许气流到电池盒的单向阀并且阻止从电池盒到周围大气的气流。 外壳包括剪刀升降机,其包括具有在终端处和中心位置枢转连接的臂的剪刀联动单元。 剪刀连杆机构可通过气缸从缩回位置移动到延伸位置。 选择性地释放外壳的内部加压,并且在剪刀升降机架延伸穿过外壳的开口之前,锁定机构缩回。
