    • A collapsible floating apparatus for controlling a valve includes a floating device and a collapsible lever. The collapsible lever includes a first member rotatably coupled to the valve, and a second member attached to the floating device at one end and rotatably coupled to the first member adjacent another end. The apparatus has a retracted position for shipping and storage, and operational positions. In the position, the second member, or the first and second members together, are brought adjacent to the valve. In operational positions, the first and second members act as a single lever to relay the buoyancy of the floating device drives to the valve. An adjusting member is provided for adjusting a relative position or angle between the first and second members, which in turn adjusts a water level.
    • 用于控制阀的可折叠浮动装置包括浮动装置和可折叠杆。 可折叠杆包括可旋转地联接到阀的第一构件和在一端附接到浮动装置的第二构件,并且可旋转地联接到邻近另一端的第一构件。 该装置具有用于运输和存储以及操作位置的缩回位置。 在该位置,第二构件或第一和第二构件一起被附接到阀。 在操作位置,第一和第二构件用作单个杠杆以将浮动装置驱动器的浮力中继到阀。 提供调节构件,用于调节第一和第二构件之间的相对位置或角度,这又调整了水位。
