    • A protecter for a riser connected to an underground water pipe and sprinkler head attached at a top portion thereof includes an elongate hollow body member having an upper portion with an upper opening and a lower portion with a lower opening, each opening being defined by a rim on respective upper and lower portion. The body defines an interior space for housing a riser and sprinkler head therein and has a lower portion including a pair of slots formed therein for fitting the body over an underground water pipe, and an upper portion further including a concave hood member extending laterally outwardly and downwardly of the rim of the upper opening and defining a cavity. The hood member has a lower edge portion for engaging a ground surface to limit downward travel of the protecter. The slots have an open lower portion and an arcuate upper portion for engaging the upper surface of an underground water pipe. The protecter also includes a plurality of spaced flanges extending beneath the hood member and engaged with the body to inhibit rotative motion of the hood member by positioning the flanges into a ground surface. The lower edge portion is located in a plane beneath an underground water pipe.
    • 用于连接到地下水管的提升管的保护器和附接在其顶部的喷洒头包括细长的中空本体构件,其具有具有上开口的上部和具有下开口的下部,每个开口由边缘限定 在相应的上部和下部。 主体限定了用于将升降器和喷洒头容纳在其中的内部空间,并且具有下部,其包括形成在其中的一对槽,用于将主体装配在地下水管上,以及上部,还包括向外横向向外延伸的凹形罩构件, 向下并且限定一个空腔。 罩构件具有下边缘部分,用于接合地面以限制保护器的向下行进。 槽具有敞开的下部和用于接合地下水管的上表面的弧形上部。 保护器还包括多个间隔的凸缘,其在罩部件的下方延伸并与主体接合,以通过将凸缘定位在地面中来阻止罩部件的旋转运动。 下边缘部分位于地下水管下面的平面内。
