Abstract

The present invention provides a device for removing internal blockage materials ( 10 ) from a fluid-conveying line ( 3 ), said device comprising a cutting tool ( 9 ) activated by a rotary actuator ( 8 ), in which: the cutting tool ( 9 ) is positioned at the front of the device; and the cutting tool ( 9 ) comprises a diameter that is smaller than the internal diameter of the fluid-conveying line ( 3 ).

First claim

The invention claimed is:

1. A device for removal of internal blockage materials from a fluid-conveying line, the device comprising:
a cutting tool activated by a rotary actuators;
a protective coating partially wrapping the device; and
a shaft to transfer a rotation force between the rotary actuator and the cutting tool,
wherein the cutting tool is positioned at the front of the device and the diameter of the cutting tool is smaller than the internal diameter of the fluid-conveying line,
wherein the front of the device is on the side of the device advancing into the fluid conveying line,
wherein the cutting tool is held outside the protective coating, and
wherein the shaft is supported by brackets inside the protective coating.

2. The device of claim 1 ,
wherein the protective coating includes casters on an external wall of the protective coating, and
wherein the casters comprise a controlled power supply to move the device.

3. The device of claim 2 , further comprising:
a longitudinal force operating system adapted to exert longitudinal force on the cutting tool,
wherein the longitudinal force operating system is attached internally to the protective coating.

4. The removal device of claim 2 , wherein the protective coating includes external retractable fastening clips configured to be attached to the internal wall of the fluid-conveying line.

5. The device of claim 1 , further comprising:
a longitudinal force operating system to exert longitudinal force on the cutting tool,
wherein the longitudinal force operating system is attached internally to the protective coating.

6. The device of claim 5 , wherein the protective coating includes external retractable fastening clips configured to be attached to the internal wall of the fluid-conveying line.

7. The device of claim 1 , wherein the protective coating includes external retractable fastening clips configured to be attached to an internal wall of the fluid-conveying line.

8. The device of claimer 1 ,
wherein the protective coating includes casters on an external wall of the protective coating, and
wherein the casters comprise a controlled power supply to move the device.

9. The device of claimer 1 , further comprising:
a longitudinal force operating system adapted to exert longitudinal force on the cutting tool,
wherein the longitudinal force operating system is attached internally to the protective coating.

10. The device of claimer 1 , wherein the protective coating includes external retractable fastening clips configured to be attached to the internal wall of the fluid-conveying line.
