Abstract

A repairing system ( 2 ) is used for applying an adhesive to a location to be repaired underwater in a container. The repairing system ( 2 ) comprises a movable and remotely controlled repairing robot ( 10 ) that is configured to be driven underwater. The repairing robot ( 10 ) comprises a repairing module (12) that is configured to be coupled with an adhesive applying module ( 34 ). The adhesive applying module ( 34 ) is configured to dispense an adhesive on the location to be repaired. Further, a repairing method is described.

First claim

What is claimed is:

1. A repairing system for applying an adhesive to a location to be repaired underwater in a container, the system comprising:
a movable and remotely controlled repairing robot that is configured to be driven underwater, the repairing robot comprising a repairing module, the movable and remotely controlled repairing robot being constructed modularly, the repairing module being a central repairing module that provides respective interfaces for connecting further modules, the repairing module being configured to be coupled with an adhesive applying module, the adhesive applying module being configured to dispense an adhesive on the location to be repaired, the repairing module comprising two driving interfaces each configured to be coupled with a corresponding driving module having at least one wheel, which ensures the movability of the repairing robot;
the repairing module being configured to be coupled with a cleaning module; and
the repairing module having a functional interface configured to be coupled with the adhesive applying module and the cleaning module selectively.

2. The system of claim 1 , wherein the cleaning module comprises at least one cleaning brush unit.

3. The system of claim 1 , wherein the adhesive applying module comprises an appliance brush.

4. The system of claim 3 , wherein the adhesive applying module has an outlet for dispensing the adhesive on the location to be repaired, and wherein the outlet is assigned to the appliance brush.

5. The system of claim 1 , wherein the repairing module is configured to be coupled with a location finding module and/or a leakage determination module.

6. The system of claim 1 , further comprising at least one camera module.

7. A repairing method to be performed underwater in a container using the repairing system as recited in claim 1 , the method comprising:
driving the movable and remotely controlled repairing robot underwater to the location to be repaired within the container; and
applying an adhesive on the location to be repaired underwater, the adhesive being brushed on the location to be repaired underwater.

8. The repairing method according to claim 7 , further comprising cleaning the location to be repaired prior to the appliance of the adhesive.

9. The repairing method according to claim 7 , localizing the location to be repaired by using an Alternating Current Field Measurement (ACFM) technique and/or by determining an amount of leakage.

10. A repairing system for applying an adhesive to a location to be repaired underwater in a container, the system comprising:
a movable and remotely controlled repairing robot that is configured to be driven underwater, the repairing robot comprising a repairing module, the movable and remotely controlled repairing robot being constructed modularly, the repairing module being a central repairing module that provides respective interfaces for connecting further modules, the repairing module being configured to be coupled with an adhesive applying module, the adhesive applying module being configured to dispense an adhesive on the location to be repaired, the repairing module comprising two driving interfaces each configured to be coupled with a corresponding driving module having at least one wheel, which ensures the movability of the repairing robot; and
the adhesive applying module comprising a rotating appliance brush.
