SECURITY DEVICE |
摘要 |
A security device is configured to limit access and prevent removal of a backflow preventer connected to a fire hydrant. The security device includes an upper enclosure rotationally and detachably coupled to a lower enclosure. The upper enclosure has an upper enclosure left end and the lower enclosure comprises a lower enclosure left end each being configured to accommodate a portion of the fire hydrant. An upper access door is attached to the upper enclosure and permits and restricts access to the backflow preventer. A side door is attached to the lower enclosure and permits and restricts access to the backflow preventer to install a hose to the backflow preventer. A plurality of height adjustment legs are attached to the lower enclosure to adjust a height of the lower enclosure from ground and to carry weight of the security device which avoids plastic deformation of the backflow preventer. |

1. A security device configured to limit access and prevent removal of a backflow preventer connected to a fire hydrant, the security device comprising:
an upper enclosure rotationally and detachably coupled to a lower enclosure wherein the upper enclosure further comprises an upper enclosure left end and the lower enclosure comprises a lower enclosure left end each being configured to accommodate a portion of the fire hydrant; an upper access door mechanically coupled to the upper enclosure wherein the upper access door permits and restricts access to the backflow preventer; a side door mechanically coupled to the lower enclosure wherein the side door permits and restricts access to the backflow preventer to install a hose to the backflow preventer; a plurality of height adjustment legs mechanically coupled to the lower enclosure to adjust a height of the lower enclosure from ground and to carry weight of the security device which avoids plastic deformation of the backflow preventer. |
