Fire hydrant cover including a controller coupled with a transceiver and a lock mechanism

摘要

A protective-fire-hydrant-cover comprising an operating-nut-extender and a protective-fire-hydrant-casing. The operating-nut-extender is firmly coupled with an operating-nut of a fire-hydrant such that when the operating-nut-extender rotates, the operating-nut rotates therewith, the operating-nut-extender includes an inner-groove exhibiting a substantially circular shape. The protective-fire-hydrant casing includes a lock-mechanism therein, which includes a latch. The latch moves between at least a locked and un-operable position and an unlocked position. The protective-fire-hydrant-casing fits over the operating-nut-extender such that it covers the operating-nut-extender and the latch aligns with the groove. When the latch moves to locked and un-operable position the latch enters the inner-groove thus internally locking the protective fire-hydrant-casing with the operating-nut-extender thus locking the protective fire-hydrant-cover onto the fire-hydrant. When the latch is in locked and un-operable position, the protective-fire-hydrant-casing may freely rotate about the operating-nut-extender. When the latch moves to the unlocked position, the protective-fire-hydrant-casing unlocks from the operating-nut-extender.

主权项

1. A protective fire hydrant cover comprising:
an operating nut extender, adapted to be firmly coupled with an operating nut of a fire hydrant such that when said operating nut extender is rotated, said operating nut rotates therewith, said operating nut extender including an inner groove exhibiting a substantially circular shape; and a protective fire hydrant casing including a lock mechanism therein, said lock mechanism including a latch, said latch being adapted to move between at least a locked and un-operable position and an unlocked position, said protective fire hydrant casing being adapted to be fitted over said operating nut extender such that said protective fire hydrant casing covers said operating nut extender and said latch is aligned with said groove, a transceiver adapted to transmit and receive signals via an antenna; and a controller, coupled with said transceiver and with said lock mechanism, said controller indicating to said lock mechanism to move said latch at least between said locked and un-operable position and said unlocked position according to signals indicative thereof received by said transceiver, wherein when said latch moves to said locked and un-operable position said latch enters said inner groove thus internally locking said protective fire hydrant casing with said operating nut extender and thus locking said protective fire hydrant cover onto said fire hydrant, wherein when said latch is in said locked and un-operable position said protective fire hydrant casing is free to rotate about said operating nut extender without rotating said operating nut extender, and wherein when said latch moves to said unlocked position, said protective fire hydrant casing is unlocked from said operating nut extender.
