Description

Buoyancy Device for Maintenance of Submarine Power Facilities The present invention relates to a buoyancy device for the maintenance of underwater power facilities, and more specifically, to a buoyancy device for the maintenance of underwater power facilities that can generate buoyancy to raise the power facilities from the seabed to the surface of the water without the assistance of external lifting equipment or personnel when maintaining power facilities installed on the seabed. This project (result) is the result of the Local Government-University Cooperation-based Regional Innovation Project, conducted in 2024 with funding from the Ministry of Education and support from the National Research Foundation of Korea. (2021RIS-002) This work was supported by the Korea Institute of Energy Technology Evaluation and Planning (KETEP) Grant funded by the Korea Government through MOTIE (Instrumentation, Diagnostics and Reliability Assessment for MVDC Systems) under Grant 20225500000120 Submarine power facilities are located in an environment where maintenance is difficult compared to offshore or onshore power facilities. When these facilities break down or require maintenance, they must be salvaged from the seabed or accessed directly, which presents a problem as it requires salvage equipment, diving personnel, and complex procedures. In other words, existing methods for salvaging underwater facilities have limitations, such as high costs and long working hours. Therefore, there is a need for a device that can salvage underwater facilities more easily and quickly. Korean registered patent [10-1375362] discloses a static and dynamic positioning system and method for an offshore structure using real-time monitoring of the seabed. FIG. 1 is a block diagram of a buoyancy device for maintenance of a submarine power facility according to one embodiment of the present invention. FIG. 2 is a block diagram showing the detailed configuration of the buoyancy device of FIG. 1. FIG. 3 is a block diagram showing the detailed configuration of the equipment fixing part of FIG. 1. FIG. 4 is a block diagram showing a sensor unit provided inside the power equipment of FIG. 1. FIG. 5 is a block diagram showing a remote control device provided on the outside of FIG. 1. FIG. 6 is a conceptual diagram showing an example in which the buoyancy device of FIG. 1 is fixed to the equipment fixing part. FIG. 7 is a conceptual diagram showing an example in which the fixation of the buoyancy device is released as buoyancy is generated in the buoyancy device of FIG. 6.
