Description

Self-propelled device for deep-buried submarine cable laying in intertidal zone

technical field

The invention relates to a cable laying device.

Background technique

With the rapid development of the marine economy, island power supply, offshore wind power construction, and offshore oil platform power supply all require submarine cables to transmit power and signals across the sea. Submarine cable lines are easily damaged by external forces such as anchors and trawling operations. Burying to a certain depth under the seabed is a protection method commonly used at home and abroad, which is economical and practical.

When our country built an offshore wind farm in the East my country Sea, it encountered a long-distance intertidal zone. Since ships could not enter, the traditional towed water jet burying plow could not be used. In addition, when excavators were used for pre-digging trenches, the effective operation time was limited. , and the trenches are easy to be washed and filled by tidal water, resulting in the deep burial of submarine cables in the intertidal zone, which is a major technical difficulty in the field of submarine cable construction.

The cable operation can be conveniently carried out through the two cable racks at the top and the rear.

The top fairlead is installed on the top of the lifting arm, and the lifting arm is hydraulically driven to adjust the height of the top fairlead. The top fairlead is provided with an operating platform, and the rear fairlead is installed on the liftable platform. superior. Realize the adjustment of the height of the fairlead.

The top fairlead and the rear fairlead are built in a profile structure, forming an arc shape. It is convenient to realize the direction conversion of the cable from the rear of the fairlead to the direction of burying.

The arc bending radius of the top fairlead and the rear fairlead is larger than the minimum bending radius of the cable. Prevent the cable from being damaged due to excessive bending.

The top fairlead and the rear fairlead are provided with detachable active conveying cable laying machines. The active traction and transportation of cables can be carried out according to the actual situation.

The crawlers of the crawler-type traveling device are made of rubber materials. The rubber material is light, wear-resistant and seawater corrosion-resistant.

Beneficial effects: It overcomes various drawbacks of traditional excavators and towed water-jet burying plows for deep burial of intertidal submarine cables, effectively solves the impact of intertidal hydrometeorology on traditional equipment, high operating efficiency, and safe and reliable product performance , Easy to operate, has a wide range of popularization and application value.

detailed description

The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1 , the self-propelled device for deep laying of submarine cables in the intertidal zone includes a crawler-type walking device 1 , an engine 3 , and a console 4 .

In order to realize the deep-buried laying operation of submarine cables in shallow water areas and intertidal zones, the engine 3 and the console 4 are arranged on the hydraulically driven liftable platform 5, and the crawler-type walking device 1 is made of rubber material , the top of the crawler-type walking device 1 is provided with a lifting arm 9, the top of the lifting arm 9 is equipped with a top fairlead 6, and the lifting arm 9 is hydraulically driven to adjust the height of the top fairlead 6, and the top fairlead 6 The frame 6 is provided with an operating platform 8, and a rear fairlead 7 is installed on the described liftable platform 5.
