AI Technical Summary
Existing submarine pipeline and cable backfilling operations are time-consuming and costly, especially in deep trenches where they are inefficient and easily affected by ocean currents, leading to inaccurate backfilling and waste.
Design a special vessel efficiency improvement device for submarine pipeline and cable backfilling. It adopts a support frame, a mobile crane, a guide assembly and a material unloading channel to realize assembly line operation, reduce the number of times the vessel is moved, and improve the accuracy and efficiency of material unloading by using a tapered duct and a material unloading pipe.
It improved backfilling efficiency by more than 50%, reduced backfill waste, avoided the use of cranes and grab buckets, and achieved efficient and continuous submarine cable backfilling.

Abstract
Claims
1. A backfilling device for a submarine pipeline and cable backfilling vessel for improving efficiency after laying a submarine pipeline, characterized in that, The device includes a support frame and several side walls mounted on the support frame. A mobile overhead crane is slidably mounted on the side walls. The side walls are arranged in pairs to form a material unloading space. A material unloading channel is provided in the material unloading space. One end of the material unloading channel is connected to the mobile overhead crane, and the other end extends into the trench. Backfill material is provided inside the mobile overhead crane, and the mobile overhead crane can slide back and forth relative to the side walls so that the backfill material inside the mobile overhead crane gradually fills the trench.
2. The device according to claim 1, characterized in that, The material unloading channel includes a tapered duct and a material unloading pipe. One end of the tapered duct is connected to the moving overhead crane, and the other end is connected to the material unloading pipe. The end of the material unloading pipe that is not connected to the tapered duct extends into the trench.
3. The device according to claim 2, characterized in that, Along the direction of the backfill material's descent, the cross-sectional area of the tapered conduit gradually decreases.
4. The device for efficiency improvement of a pipelaying vessel according to claim 2, characterized in that, The discharge pipe includes several discharge guide tubes, which are connected in sequence to form a tubular discharge pipe. The number of discharge guide tubes is limited to allow the discharge pipe to extend into the trench.
5. The device according to claim 4, characterized in that, The discharge pipe also includes clamps, and adjacent discharge pipes are connected by clamps.
6. The device according to claim 1, characterized in that, The inner wall of the feeding guide tube is lined with a wear-resistant layer.
7. The device according to claim 1, characterized in that, The efficiency-enhancing device for submarine pipeline and cable backfilling vessels also includes a guide assembly, which is installed on the side wall to guide the linear movement of the mobile crane. There are two side walls, which are arranged opposite each other.
8. The device according to claim 7, characterized in that, The guide assembly includes two spaced-apart guide rails, which are respectively mounted on two opposite side walls.
9. The device according to claim 8, characterized in that, The bottom of the mobile overhead crane is equipped with pulleys, which are slidably connected to the guide rails.
10. The device according to claim 8, characterized in that, The guiding assembly also includes a motor, which is located at both ends of the guide rail and is used to drive the mobile crane to move back and forth.
