Abstract
Description
Technical Field
[0001] This utility model relates to the field of submarine cable laying technology, and in particular to a submarine cable laying plow for use on hard seabed conditions. Background Technology
[0002] In offshore wind power projects, the successful laying of submarine cables is a crucial step in ensuring power transmission. However, seabed geological conditions are complex and diverse, especially when encountering hard seabeds with shallow or no overburden. Traditional submarine cable laying equipment often uses water jets to clear the cable path by impacting silt. While this method is effective on soft seabeds, it is ineffective in breaking or removing rocks in rock-embedded seabeds containing a large amount of rock, making it impossible to form a stable cable channel. This not only affects the efficiency of cable laying but may also lead to equipment damage or work interruptions during construction.
[0003] Therefore, there is a need for a laying equipment that can efficiently handle rock-embedded seabeds to ensure the smooth laying of submarine cables and avoid delays and additional costs caused by rock obstruction. Utility Model Content
[0004] To address the problems mentioned in the background section, the present invention adopts the following technical solution: A submarine cable laying plow for hard seabed conditions is installed as a whole on the frame of a submarine cable laying machine, including a plow blade mounting component, a support frame and a motor; The motor and support frame are fixedly mounted on the machine frame; A rotating shaft is provided between the two mounting heads at the lower front end of the support frame, and the motor is used to control the rotation of the rotating shaft; The plow blade mounting component is wrapped around the shaft surface of the rotating shaft in a roller-like structure; The plow blade mounting component is equipped with multiple toothed plow blades.
[0005] In some embodiments, the support frame is provided with a plurality of high-pressure water guns; The nozzles of multiple high-pressure water guns are all located on the surface of the support frame and on the opposite side of the plow blade mounting component.
[0006] In some embodiments, a plurality of plow blades are evenly distributed around the outer periphery of the plow blade mount.
[0007] In some embodiments, the plow blade is made of a wear-resistant alloy material, and the support frame is made of a corrosion-resistant steel structure.
[0008] Compared with the prior art, the beneficial effects of this utility model are: This invention provides a cable laying plow for hard seabed conditions. A plow blade is installed at the front of the frame of a conventional cable laying machine to break up rocks along the cable laying path, making the seabed suitable for cable laying and overcoming the limitations of traditional water-jetting methods on hard seabeds. Simultaneously, a high-pressure water gun is installed on the opposite side of the plow blade, using high-pressure water to wash away the broken rock fragments, ensuring a smooth and clean path and preventing debris from obstructing subsequent cable laying. This device integrates mechanical crushing and hydraulic cleaning functions, effectively solving the technical problem of laying cables smoothly on rock-embedded seabeds, greatly improving work efficiency, reducing construction downtime and equipment wear, and is particularly suitable for cable laying in complex seabed environments, effectively reducing construction costs and risks.

Its features include a plow blade mounting component 2, a support frame 3, and a motor 4; the motor 4 and the support frame 3 are fixedly mounted on the frame 10; a rotating shaft 5 is provided between two mounting heads at the lower front end of the support frame 3, and the motor 4 is used to control the rotation of the rotating shaft 5; the plow blade mounting component 2 is wrapped around the shaft surface of the rotating shaft 5 in a roller-like structure; and multiple toothed plow blades 1 are mounted on the plow blade mounting component 2.
[0013] Further reference Figure 2 As shown, preferably, the support frame 3 is provided with multiple high-pressure water guns inside; the nozzles 6 of the multiple high-pressure water guns are all opened on the surface of the support frame 3 and are located on the opposite side of the plow blade mounting component 2.
[0014] Preferably, multiple plow blades 1 are evenly distributed on the outer periphery of the plow blade mounting component 2; the plow blades 1 are made of wear-resistant alloy material, and the support frame 3 is made of corrosion-resistant steel structure.
[0015] This invention, by setting up a rotating plow blade mounting component 2 and a plow blade 1, can break rocks and hard sediments on the seabed, ensuring a smooth path for submarine cable laying. The plow blade 1 operates by mechanical rotation and is made of wear-resistant alloy material to ensure durability under high-intensity operation.
[0016] Furthermore, in conjunction with a high-pressure water gun, the high-pressure water flow removes shattered rock debris and silt, ensuring a clean and smooth laying path. The high-pressure water gun has adjustable water pressure, allowing for flexible adjustments to the cleaning intensity based on different seabed conditions.
[0017] The support frame 3 can be fixed to the frame 10 of the submarine cable laying machine by bolt connection to ensure that the device is stable and reliable during operation.
[0018] The motor 4 is mounted on the laying vehicle frame and is waterproof; the device provides torque output to drive the plow blade 1 to perform continuous rotational work on the seabed, breaking rocks and hard sediments.
