Abstract
A gasketless waterproof ingress prevention enclosure for electronics wherein the enclosure does not rely on traditional sealing means to restrain water. The enclosure includes a five-sided open bottom air tight cavity comprising a liquid volume fluidly coupled to a gas volume creating a gas-fluid coupling layer, rising in elevation within cavity. Changing cavity pressure equal to rising compressed liquid pressure prevents exposure to said electronic enclosure components to a maximum design depth of 15 feet of water below surface level or a column height of 15 feet of water over the bottom of the enclosure bell bottom, independent of the enclosure's distance below surface grade. The apparatus forms a telescoped and recessed inner chassis assembly in its fully closed position. The prevention enclosure also provides a method for sealing comprising the steps of gasketless water prevention, electronics mounting, and water damage component protection.

Claims
  • 1. A gasketless, one and one-half atmospheres of pressure waterproof electronics and electrical component enclosure assembly comprising: a five-sided open bottom air tight enclosure which utilizes known fluid and pressure dynamics formulas to allow liquids to rise within the enclosure thereby pressurizing the atmospheric gas contained therein to a pressure equal to the rising liquid pressure; thus, preventing exposure to said electronic or electrical equipment contained within the pressurized gas area within the enclosure to a further height than the opening access cavity for a pressure differential prevention of water ingress and a gasketless enclosure attached thereto.
  • 2. The apparatus of claim 1 further comprising: a concealed locking or latching entry feature, a guide and bracketry inner chassis, rail sleeve telescoping guide assembly, component mounting rear tray panel slidingly coupled thereto, and an open bottom pressure differential cavity and skirt coupled therein.
  • 3. The apparatus of claim 1 further comprising: A submersible telemetry, control, telecommunications or electronics assembly wherein a concealed locking or latching entry feature, a guide and bracketry inner chassis, rail sleeve telescoping guide assembly, component mounting rear tray panel slidingly coupled thereto, and an open bottom pressure differential cavity and skirt coupled therein for use with telecommunications, utility, energy, electrical and electronics power or control applications.
  • 4. The apparatus of claim 2 wherein: said five-sided open bottom air tight cavity comprises a liquid volume fluidly coupled to a gas volume creating a gas-fluid coupling layer, said gas-fluid coupling layer interface rising in elevation within said cavity thereby changing cavity pressure equal to the rising compressed liquid pressure to a maximum design pressure of 1.5 atmospheres, thereby preventing exposure to said electronic and electrical enclosure to a maximum design depth of 15 feet of water below surface level or equivalent to a column height of 15 feet of water over the bottom of the enclosure bell bottom, independent of the enclosure's distance below surface grade.
  • 5. A guide and bracketry inner chassis comprising: guides and bracketry allowing the protected equipment to be withdrawn via and through the open bottom of the “bell” enclosure in order for the electronic or electric components to be serviced, a telescoping rail and guide rack assembly, and a five sided tray panel.
  • 6. The apparatus of claim 3 wherein: said guides and bracketry include sleeve and telescoping features to facilitate full height 150% extension utilizing a rack and rail system with nested guides in fully retracted position.
  • 7. The apparatus of claim 1 further comprising: a concealed locking or latching entry feature allowing the protected equipment to be secured in place where access is gained through the open bottom of the “bell” enclosure.
  • 8. The apparatus of claim 1 further comprising: a means for counterbalancing weight distribution allowing the protected equipment and submersible enclosure to be of lesser weight while still providing the necessary pressure differential to seal the assembly.
  • 9. A method for providing prevention of water ingress to an electronics or electrical enclosure assembly, comprising the steps of: Gasketless water sealing to a depth of fifteen feet, electronics and electrical enclosure and mounting, and protection of said electronics and electrical components from water damage.
