Abstract
A sewer cleaning apparatus which has a hollow cylindrical body propelled by a plurality of water jets with a clam shell opening on the front of the apparatus operated by a plurality of piston assemblies that are attached to the sides of the cylindrical body. The apparatus is propelled by high pressure water ejected from the apparatus in a rearward direction. The high pressure water operates the piston assembly opening the clam shell and provides forward thrust for the apparatus allowing the hollow bucket type object to trap solids inside apparatus.
Claims5
An apparatus for removing solids from sewers comprising:
- a hollow cylindrical body and a plurality of high-pressure water jets configured to provide forward thrust to the cylindrical body;
- and
- wherein the cylindrical body has a front end, a first clam shell half and a second clam shell half, the first and second clam shell halves being hingedly attached to one another to form a clam shell, the clam shell being situated at the front end of the cylindrical body and operated by at least one piston assembly that is configured to open and close the clam shell on the front end of the cylindrical body in response to water pressure supplied by a water jet manifold assembly situated on a rear end of the apparatus.
