Abstract

A cover assembly for covering a vessel comprising a main cover comprising at least a first outlet opening adapted for connection to a pipe, and a second opening surrounded by a flat region adapted for placement of a gasket; an access cover comprising a flat region adapted for mating with the flat region of said main cover; and provisions for the sealing of at least one cord passing between the main cover and the access cover. In other embodiments, the cover assembly is provided with an engagement feature adapted for engagement with a hook-shaped hanger rod. Sewage basin assemblies are also provided which incorporate these cover assemblies.

Claims

1. A cover assembly for covering a vessel, said cover assembly comprising:

a. a main cover comprising at least a first outlet opening adapted for connection to a pipe, and a second opening surrounded by a flat region adapted for placement of a gasket;

b. an access cover comprising a flat region adapted for mating with said flat region of said main cover; and

c. cord sealing means for the sealing of at least one cord passing between said main cover and said access cover.

2. The cover assembly as recited in claim 1, further comprising a gasket disposed between said main cover and said access cover.

3. The cover assembly as recited in claim 2, wherein said gasket comprises a cord sealing portion comprised of at least one cord seal groove adapted for receiving a cord.

4. The cover assembly as recited in claim 3, further comprising a cord seal block comprising at least one cord seal groove adapted for receiving a cord.

5. The cover assembly as recited in claim 4, wherein said main cover further comprises a pocket for holding and sealing to said cord sealing portion of said gasket.

6. The cover assembly as recited in claim 4, wherein said cord seal block is in contact with said cord sealing portion of said gasket, such that said at least one cord seal groove of said gasket and said at least one cord seal groove of said cord seal block form a cord seal passageway.

7. The cover assembly as recited in claim 1, further comprising an engagement feature adapted for engagement with a hook-shaped hanger rod.

8. A sewage handling system comprising

a. a basin for receiving a liquid, said basin comprising a body with at least one inlet opening and an open top comprising a flat region adapted for receiving a cover assembly;

b. a cover assembly comprising;

i. a main cover comprising at least a first outlet opening adapted for connection to a pipe, and a second opening surrounded by a flat region adapted for placement of a gasket;

ii. an access cover comprising a flat region adapted for mating with said flat region of said main cover; and

iii. cord sealing means for the sealing of at least one cord passing between said main cover and said access cover; and

c. a pump disposed in said basin and operatively connected by a discharge pipe to said first outlet opening of said main cover.

9. The sewage handling system as recited in claim 8, wherein said cover assembly further comprises a gasket disposed between said main cover and said access cover.

10. The sewage handling system as recited in claim 9, wherein said gasket comprises a cord sealing portion comprised of at least one cord seal groove adapted for receiving a cord.

11. The sewage handling system as recited in claim 10, wherein said cover assembly further comprises a cord seal block comprising at least one cord seal groove adapted for receiving a cord.

12. The sewage handling system as recited in claim 11, wherein said main cover further comprises a pocket for holding and sealing to said cord sealing portion of said gasket.

13. The sewage handling system as recited in claim 11, wherein said cord seal block is in contact with said cord sealing portion of said gasket, such that said at least one cord seal groove of said gasket and said at least one cord seal groove of said cord seal block form a cord seal passageway.

14. The sewage handling system as recited in claim 8, wherein said cover assembly further comprises an engagement feature adapted for engagement with a hook-shaped hanger rod.

15. The sewage handling system as recited in claim 14, further comprising a level switch assembly comprising a hook-shaped hanger rod engaged with said engagement feature of said cover assembly, and at least one level switch attached to said hook-shaped hanger rod.

16. The sewage handling system as recited in claim 15, wherein said at least one level switch is a float switch.

17. The sewage handling system as recited in claim 15, wherein said hanger rod is J-shaped.

18. The sewage handling system as recited in claim 15, further comprising a second level switch attached to said hook-shaped hanger rod.
