Description

Technical Field

[0001] The utility model relates to the technical field of submarine buried mechanical devices, in particular to a non-contact trenching device for deep sea. Background Art

[0002] Non-contact trenching refers to the operation of using water pressure to punch trenches on the seabed according to the path of submarine cables and optical cables (called routing) in offshore wind power, photovoltaic or marine communication projects, and burying the cables under the seabed. The main work involved in the non-contact trenching construction process includes dragging the trenching equipment along the cable route, and punching trenches of specified depth on the bottom of the water to allow the cables to be placed on the seabed later.

[0003] At present, the main operation mode of non-contact trenching equipment is remote operation. Due to the complex construction environment and tasks, the equipment status and environmental parameters are difficult to obtain intuitively. During construction, it relies on a variety of sensors carried by the equipment. The operator observes the changes in equipment values and limited image information, manually adjusts the equipment's travel speed and direction, and controls the impact action. The operation accuracy is not high. During long-term construction, operators are prone to fatigue and lack of concentration, resulting in reduced construction efficiency, equipment failure and other unexpected situations. For this reason, we proposed a non-contact trenching equipment for deep sea use. Utility Model Content
