Aboveground Rectangular Secondary Containment Generator Base Tank with Internal Flexible Bladder

Abstract

The present invention is a containment tank or a generator set including an outer tank and an inner flexible tank that offers a storage area for diesel fuel for a diesel engine powered generator set. So that the generator set diesel engine have ready source of clean diesel fuel the inner flexible tank provides a corrosion-free storage area that will not corrode or contaminate the diesel fuel. The outer tank is designed to provide a structure that not only protects the inner tank from damage, but acts as a support structure for the diesel engine generator set and other components (enclosure, switchgear, etc.) that are needed for the generator sets protection from wind, rain or snow or to act as control devices for diesel engine generator set. Also, since the design of the inner tank is flexible, it can be replaced easily through a manway formed on the outer tank without having to disconnect or disassemble the generator set.

         2 . The tank of  claim 1  wherein the inner tank includes a rim releasably secured to an outer surface of the top wall 
     
     
         3 . The tank of  claim 2  further comprising a cover plate releasably secured to the top wall over the rim. 
     
     
         4 . The tank of  claim 3  further comprising a number of fasteners affixing the cover plate to the top wall over the rim. 
     
     
         5 . The tank of  claim 4  wherein the rim is compressed between the cover plate and the top wall to form a fluid-tight seal. 
     
     
         6 . The tank of  claim 3  wherein the cover plate includes at least one fitting therein. 
     
     
         7 . The tank of  claim 2  wherein the rim is integrally formed with the inner tank. 
     
     
         8 . The tank of  claim 1  further comprising at least one support member secured to at least one of the pair of side walls. 
     
     
         9 . The tank of  claim 8  wherein the at least one support member includes a lifting opening formed therein. 
     
     
         10 . The tank of  claim 1  further comprising a removable end plate secured between the end walls and spaced from the end wall spaced inwardly from the end of the bottom wall. 
     
     
         11 . A generator set comprising:
 a) a containment tank including an outer tank including a bottom wall, a pair of opposed side walls connected to the bottom wall, a pair of opposed end walls each connected to the bottom wall and between the side walls, one end wall spaced inwardly from one end of the bottom wall, and a top wall connected to each of the pair of side walls and the pair of end walls, the top wall defining an access opening therein, at least one generator system component attachment assembly located on at least one of the side walls, the at least one attachment assembly adapted to provide an attachment point for a generator system component to the tank; and a inner tank disposed within the outer tank, the inner tank formed of a flexible and collapsible material; and   b) at least one generator system component secured to the at least one attachment assembly.   
     
     
         12 . The generator set of  claim 11  wherein the inner tank includes a rim releasably secured to an outer surface of the top wall 
     
     
         13 . The generator set of  claim 12  further comprising a cover plate releasably secured to the top wall over the rim. 
     
     
         14 . The generator set of  claim 13  further comprising a number of fasteners affixing the cover plate to the top wall over the rim. 
     
     
         15 . The generator set of  claim 14  wherein the rim is compressed between the cover plate and the top wall to form a fluid-tight seal. 
     
     
         16 . The generator set of  claim 13  wherein the cover plate includes at least one fitting therein. 
     
     
         17 . The generator set of  claim 12  wherein the rim is integrally formed with the inner tank. 
     
     
         18 . The generator set of  claim 11  further comprising at least one support member secured to at least one of the pair of side walls. 
     
     
         19 . The generator set of  claim 18  wherein the at least one support member includes a lifting opening formed therein. 
     
     
         20 . The generator set of  claim 20  further comprising a removable end plate secured between the end walls and spaced from the end wall spaced inwardly from the end of the bottom wall.
