Abstract
A spill containment system is attachable to a riser pipe with an axially moveable seal. The spill containment system allows access to a drop tube in the riser pipe via a removable liquid communication assembly. The spill containment system includes a sealed interstitial space, which remains sealed during installation, service and use of the system. The spill containment system is protected by a weather resistant cover assembly.
Claims20
A fluid spill collector assembly comprising:
- a primary receptacle including:
- an upper primary receptacle end having an upper primary receptacle opening;
- a lower primary receptacle end having a lower primary receptacle opening;
- a primary receptacle wall extending between said upper and lower primary receptacle ends, said primary receptacle wall defining a primary receptacle cavity;
- a secondary receptacle including:
- an upper secondary receptacle end having an upper secondary receptacle opening;
- a lower secondary receptacle end having a lower secondary receptacle opening;
- and
- a secondary receptacle wall extending between said upper and lower secondary receptacle ends, said secondary receptacle wall defining a secondary receptacle cavity,
- said primary receptacle received within said secondary receptacle cavity, said upper primary receptacle opening sealingly coupled to said upper secondary receptacle opening to form a sealed upper end of the assembly;
- and
- a single, unitary tank adapter having a base platform with an aperture extending therethrough, said base platform sealingly coupled to said primary lower receptacle opening and said secondary lower receptacle opening to form a sealed lower end of the assembly,
- said sealed upper end and lower ends of the assembly cooperating to form a sealed interstitial space between said primary receptacle wall and said secondary receptacle wall,
- wherein said primary receptacle cavity remains in fluid communication with said upper primary receptacle opening and said aperture of said tank adapter aperture while said interstitial space is sealed.
A fluid spill collector assembly comprising:
- a stationary collar having an inner peripheral surface;
- and
- a double-walled spill container assembly comprising:
- an outer receptacle having a first open upper end, said outer receptacle sized to be receivable within said collar;
- an inner receptacle having a second open upper end, said inner receptacle coupled to said outer receptacle to create a sealed interstitial space therebetween;
- and
- a seal coupled to at least one of said outer receptacle and inner receptacle, said seal slidably engageable with said inner peripheral surface of said collar to create a fluid tight seal between said collar and said spill container assembly,
- said spill container assembly axially moveable with respect to said stationary collar while said interstitial space remains sealed.
A fluid spill collector assembly comprising:
- a double-walled spill container assembly comprising:
- a primary receptacle having a primary open upper end and a primary receptacle cavity;
- and
- a secondary receptacle having a secondary open upper end a secondary receptacle cavity, said primary receptacle received within said secondary receptacle cavity via said secondary open upper end to create a sealed interstitial space between said primary receptacle and said secondary receptacle, said primary receptacle cavity remaining accessible while said interstitial space is sealed;
- and
- a vacuum system comprising:
- a vacuum generator operable to create a vacuum pressure;
- a vacuum conduit in fluid communication with said interstitial space and said vacuum generator;
- a vacuum monitoring device in fluid communication said interstitial space, said vacuum monitoring device including a processor monitoring said vacuum pressure created by said vacuum generator, said processor operable to determine a rate of change of said vacuum pressure.
A cover assembly comprising:
- a collar including:
- an upper collar portion;
- a lower collar portion;
- and
- an inner collar peripheral surface extending from said upper portion to said lower portion, said inner collar peripheral surface having at least one radial collar aperture formed therein;
- a cover ring at least partially received within said collar, said cover ring including:
- an upper ring portion;
- a lower ring portion;
- an inner ring peripheral surface extending between said upper ring portion and said lower ring portion;
- and
- an outer ring peripheral surface opposite said inner ring peripheral surface, said cover ring having at least one radial ring aperture extending from said inner ring peripheral surface to said outer ring peripheral surface;
- a fastener extending radially through said ring aperture and into said collar aperture to fix said cover ring to said collar;
- and
- a cover receivable within said cover ring, said cover blocking access to said inner collar peripheral surface and said fastener when said cover is received within said cover ring.
A method of using a fluid spill collector assembly, comprising:
- removing a cover from a cover receiving surface to expose an inner cavity of a spill receptacle;
- retrieving a drain valve actuator from within the inner cavity;
- and
- attaching the drain valve actuator to the cover receiving surface to open a drain valve disposed within the inner cavity, said step of attaching the drain valve actuator blocking a portion of the cover receiving surface,
- wherein said step of attaching the drain valve actuator prevents replacement of the cover upon the receiving surface.
A method of inspecting a drop tube of the inlet pipe, the method comprising:
- providing a double-walled spill container assembly comprising:
- a primary receptacle having a primary receptacle cavity;
- a secondary receptacle having a secondary receptacle cavity sized to receive the primary receptacle;
- and
- a tank adapter having a base platform coupled to the primary and secondary receptacles to form a sealed interstitial space therebetween, the tank adapter having an aperture in fluid communication with the primary receptacle cavity;
- accessing a liquid communication assembly received within the primary receptacle cavity, the liquid communication assembly including a drop tube riser clamp at a lower end thereof and a coupler at an upper end thereof, the drop tube riser clamp engaged with the tank adapter at the aperture;
- decoupling the liquid communication assembly from the tank adapter by disengaging the drop tube riser clamp assembly from the tank adapter, said step of decoupling the liquid communication assembly exposing the aperture of the tank adapter;
- and
- removing the drop tube from the spill receptacle by extracting the drop tube through the aperture of the tank adapter.
