Mobile collecting device for the high-pressure water jet of a water-jet tool and method of use
View Patent ↗A mobile collecting device ( 22 ) for the high-pressure water jet ( 26 ) of a water-jet tool ( 18 ), especially for working in confined places with difficult access in turbines or the like, in which a more flexible and safer operation is achieved by a closed collecting chamber ( 24 ), which extends over a large area and includes an outlet ( 30 ), and in which a rigid first collecting bed ( 34 ) formed of a first high-pressure-resistant material is arranged.
1. A mobile collecting device for a high-pressure water jet of a water-jet tool, the device comprising:
a closed collecting chamber extending over an area including an outlet and a cover;
a partition disposed within the closed collecting chamber parallel to the cover defining upper and lower collecting chambers, with the upper collecting chamber comprising
a fixed first collecting bed directly above the partition comprising
a plurality of layers, each layer formed of a hard substance as a first high-pressure-resistant material, arranged one above the other with each of the plurality of layers comprising bars formed of the first high-pressure-resistant material, the bars extending parallel in one plane next to each other with bars of consecutive layers oriented orthogonally to each other,
the outlet attached at a bottom of the upper collecting chamber to enable exit of material therefrom, and
the lower collecting chamber comprising
a second collecting bed below the partition comprising
at least one layer with openings and a moisture sensor associated with the openings operable to detect moisture discharged from the upper collecting chamber; and
an acceleration sensor suitable for detecting penetration of the high-pressure water jet through a workpiece arranged on the collecting device.
2. The collecting device as claimed in claim 1 , wherein the hard substance is tungsten carbide.
3. The collecting device as claimed in claim 1 , further comprising:
a cubic housing having an upper side and the cover at said upper side, with the collecting chamber positioned in the cubic housing, and the upper side being closed off by the cover.
4. The collecting device as claimed in claim 1 , wherein the bars in consecutive layers are in contact with each other.
5. The collecting device as claimed in claim 1 , where the closed collecting chamber is filled at the bottom with the plurality of layers.
6. The collecting device as claimed in claim 1 , where the acceleration sensor is connected to a signal processing device which, at a signal output, generates a signal for controlling the water-jet tool.
