Abstract:
A device for providing visual screening of a storage tank including a vertical sidewall having a cylindrical outer surface and an upper end, tile storage tank further including an upper end wall attached to the vertical sidewall at said upper end thereof and located radially inward from the outer surface of the sidewall, the device comprising:a. a screening structure for surrounding the storage tank, said screening structure having an upper end, a lower end, an inner surface extending between said upper and lower ends and having a first free end extending from said upper end to said lower end and a second free end extending from said upper end to said lower end, said upper end defining a first plane and said lower end defining a second plane substantially parallel to said first plane when said screening structure surrounds the storage tank said screening structure substantially conforming to said cylindrical outer surface such that said first free end and said second free end are proximate one another when said screening structure surrounds the storage tank said upper and lower ends being open when said screening structure surrounds the storage tank; and b. an elongate flexible member engaging said screening structure, at least a portion of said elongate flexible member extending across and engaging at least a portion of the upper end wall of the storage tank when said screening structure surrounds the storage tank to prevent said screening structure from moving vertically downward relative to the storage tank.
