Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of submarine cable operation and maintenance, and particularly relates to a scour protection water-permeable frame fixed-point launching device applied to a submarine cable shallow water area. BACKGROUND

[0002] With the development of submarine cable power transmission technology, submarine cables have been widely applied to offshore platform and island power supply, marine clean energy transmission, cross-regional power transmission and other fields. During the operation of submarine cables, due to the long-term scouring effect of sea currents, the submarine cables in some routing areas are prone to be exposed or have a shallow buried depth. For the exposed or shallow buried depth submarine cables, on the one hand, they are prone to suffer from anchor throwing and other external damage accidents, and on the other hand, they may be further scoured to form a suspension and cause cable damage. Once the submarine cable is damaged, the fault checking and maintenance are difficult, the maintenance period is long, and the maintenance cost is high, which brings serious social and economic losses. Therefore, it is necessary to protect the exposed or shallow buried depth submarine cables, such as throwing sandbags, stones, cement chain rows and water-permeable frames. The water-permeable frame plays a role in wave dissipation, siltation promotion and sand fixation. The water-permeable frame is placed in a certain design form. In deep water areas, large ships and tools can be used for construction, while in shallow water areas, large ships cannot enter. The traditional construction method is to use a floating ball to bind the water-permeable frame and float it to the designed position for placement by a diver. However, this method is greatly affected by sea currents and weather conditions, has many limiting factors, has low construction efficiency, and may cause the exposed or shallow buried depth submarine cable to be in the risk of external damage for a long time, which cannot guarantee the safe and stable operation of the submarine cable.
