Abstract
Non-conductive hydro-excavation wands incorporating wear sleeves are disclosed. In one embodiment, a non-conductive hydro-excavation wand includes a non-conductive pipe, a non-conductive hose within the non-conductive pipe, a hand-actuated on/off valve connected to the non-conductive hose, a rigid, non-conductive tip at one end of the non-conductive pipe, the tip having an opening that is open to the interior of the non-conductive hose; and a wear sleeve of non-conductive material surrounding at least part of the non-conductive pipe.
Claims17
A non-conductive hydro-excavation wand comprising:
- a non-conductive pipe;
- a non-conductive high-pressure hose within the non-conductive pipe;
- a hand-actuated valve connected to the non-conductive high-pressure hose;
- a rigid, non-conductive tip at one end of the non-conductive pipe, the tip having an opening that is open to the interior of the non-conductive high-pressure hose;
- and
- a wear sleeve of non-conductive material surrounding at least part of the non-conductive pipe;
- wherein:
- the wear sleeve comprises two segments, a first segment surrounding a portion of the non-conductive pipe and a second segment surrounding a portion of the non-conductive pipe connected to the non-conductive tip;
- and
- the second segment is connected to the non-conductive tip and located between the first segment and the non-conductive tip.

A non-conductive hydro-excavation wand comprising:
- a non-conductive pipe;
- a non-conductive high-pressure hose within the non-conductive pipe;
- non-conductive void filler material filling voids between the non-conductive high-pressure hose and the non-conductive pipe;
- a rigid, non-conductive tip at one end of the non-conductive pipe, the tip having an opening that is open to the interior of the non-conductive high-pressure hose;
- a hand-actuated valve connected to the non-conductive high-pressure hose and located at the opposite end of the non-conductive pipe from the non-conductive tip;
- a high-pressure release valve connected to the hand-actuated valve, where the high-pressure release valve is configured for detachable connection of a second external non-conductive high-pressure hose;
- and
- a wear sleeve of non-conductive material surrounding at least part of the non-conductive pipe, wherein:
- the wear sleeve comprises two segments, a first segment surrounding a portion of the non-conductive pipe and a second segment surrounding a portion of the non-conductive pipe connected to the non-conductive tip;
- the second segment is connected to the non-conductive tip and located between the first segment and the non-conductive tip;
- the first segment is relatively thinner than the second segment;
- and
- an attachment mechanism is located at an interface of the first segment to the second segment.

- the second segment is connected to the non-conductive tip and located between the first segment and the non-conductive tip;
- the first segment is relatively thinner than the second segment;
- an attachment mechanism is located at an interface of the first segment to the second segment;
- and
- the second segment has a wall thickness of ¼ of an inch.
