Description

Technical Field

[0001] The utility model relates to the technical field of submarine cable burial, in particular to a deep-water burial plow suitable for submarine cable laying. Background Technique

[0002] The deep-water burial plow of submarine cable is one of the important devices in the process of submarine optical cable laying. After the cable laying ship pays out the cable, the cable will sink to the seabed under the action of gravity. At the same time, the excavator on the seabed (also known as the deep-water burial plow) will work synchronously. The deep-water burial plow plays the role of a counterweight during the laying of submarine optical cables and is towed forward by the ship. It ensures that the optical cable can sink accurately and safely to the seabed and be fixed in place. In addition, when encountering rough terrain on the seabed, the deep-water burial plow can also detect the best path to prevent damage to the optical cable caused by seabed rocks. An existing deep-water burial plow suitable for submarine cable laying can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] When the existing deep-water burial plow is in use, the plow blades on the burial plow are all fixed to the frame by bolts. When the plow blades need to be replaced, professional techniques and tools may be required, which also increases the difficulty and cost of replacement. For this reason, we propose a deep-water burial plow suitable for submarine cable laying to solve the above problems. Content of the Utility Model

[0013] 1. By means of the connection component arranged between the frame and the plow blade in the present utility model, the plow blade slides up and down in the assembly seat. When it slides to the required height, the restoring force of the first spring drives the two groups of transmission blocks to slide back on the guide rods, and the transmission blocks synchronously drive the insertion blocks to insert into the slots, so as to achieve the purpose of fixing the plow blade, thus facilitating the staff to replace the plow blade. Then, by the plow blade sliding in the assembly seat, the ten groups of slots on the plow blade are aligned with the insertion blocks in sequence, and by sliding the insertion blocks into the slots, it is convenient for the staff to adjust the ditching depth of the plow blade, thereby improving its practicability.

[0014] 2. By means of the protection component arranged outside the plow blade and at the left end of the frame in the present utility model, during the process of the frame traveling on the seabed, the protection plate can protect the plow blade and the frame. When a stone hits the protection plate, the protection plate drives the slide rod to slide in the chute, and the impact force received by the protection plate continuously acts on the second spring, and the elastic force of the second spring is used to buffer the impact force on the protection plate, so as to provide a good and safe burying environment for the frame.

[0024] Through the connection component 6 provided between the frame 1 and the plow blade 5, the plow blade 5 slides up and down within the assembly seat 61. When it slides to the required height, the restoring force of the first spring 65 drives the two sets of transmission blocks 64 to slide back on the guide rod 63, and the transmission blocks 64 synchronously drive the insertion blocks 66 to insert into the slots 67, thereby achieving the purpose of fixing the plow blade 5, facilitating the replacement of the plow blade 5 by the staff. Then, through the sliding of the plow blade 5 within the assembly seat 61, the ten slots 67 on the plow blade 5 are sequentially aligned with the insertion blocks 66, and by sliding the insertion blocks 66 into the slots 67, it is convenient for the staff to adjust the ditching depth of the plow blade 5, improving its practicability.

[0025] In other embodiments, the protection component 7 includes two sets of chutes 71 provided on the outer wall of the frame 1 at the front and rear ends of the connection component 6.

[0026] Through the protection component 7 provided outside the plow blade 5 and at the left end of the frame 1, during the seabed travel of the frame 1, the protection plate 73 can protect the plow blade 5 and the frame 1. When a stone impacts on the protection plate 73, the protection plate 73 drives the slide rod 72 to slide within the chute 71, and the impact force received by the protection plate 73 continuously acts on the second spring 74, and the elastic force of the second spring 74 is used to buffer the impact force on the protection plate 73, thereby providing a good and safe burial environment for the frame 1.

[0028] Through this design, the plow blade 5 can be slid up and down within the assembly seat 61, driving the ten slots 67 to sequentially slide to align with the insertion blocks 66. Then, by releasing the push rod 68, the restoring force of the first spring 65 drives the two sets of transmission blocks 64 to slide back on the guide rod 63, and the transmission blocks 64 drive the insertion blocks 66 to insert into the slots 67, thereby achieving the purpose of adjusting the ditching depth of the plow blade 5. By observing the scale values on the side of the plow blade 5, it is convenient for the staff to understand the ditching depth of the plow blade 5.

[0029] In other embodiments, the surface of the push rod 68 is designed to be cylindrical, and the left end of the push rod 68 is designed to be spherical.

[0030] Through this design, it is convenient for the staff to operate the transmission blocks 64 through the push rod 68, improving the comfort of the staff when using the push rod 68, facilitating the staff to hold the push rod 68, and preventing the situation of hand slipping when pushing the two sets of transmission blocks 64.

[0031] In other embodiments, the sliding rod 72 is designed in a rectangular shape, and through holes adapted to the sliding rod 72 are formed in the sliding groove 71;

[0032] Through this design, the four sides of the sliding rod 72 can be fitted to the sliding groove 71, thereby improving the stability of the reciprocating sliding of the sliding rod 72 in the sliding groove 71 and preventing the situation where the sliding rod 72 is stuck in the sliding groove 71 and cannot slide.

[0033] In other embodiments, the protective plate 73 is designed in an inclined shape, and a layer of rubber pad is provided on the left end surface of the protective plate 73;

[0034] Through this design, the crushed stones that collide with the protective plate 73 can slide down along the inclined surface of the protective plate 73 to both sides of the frame 1, thereby not disturbing the forward route of the burying plow, and at the same time enabling the protective plate 73 to achieve the purpose of protecting the frame 1.

[0035] In other embodiments, the second spring 74 is fixedly arranged at the middle position of the inner wall of the sliding groove 71, and the other end of the second spring 74 is fixedly arranged at the middle position of the inner end surface of the sliding rod 72;

[0036] Through this design, the restoring force generated by the second spring 74 being squeezed by the sliding rod 72 can be evenly output to both sides of the sliding rod 72, thereby ensuring the stability of the reciprocating sliding of the sliding rod 72 in the sliding groove 71.

[0037] The present utility model provides a deep - water burying plow suitable for submarine cable laying, and the specific working principle is as follows:

[0038] During use, first, push the two groups of push rods 68 in the direction away from the assembly seat 61, so that the push rods 68 drive the two groups of transmission blocks 64 to slide on the guide rods 63, and the two groups of transmission blocks 64 stretch the first spring 65. At the same time, the transmission blocks 64 drive the insertion blocks 66 to slide out of the slots 67 in the assembly seat 61. Then, slide the plow blade 5 into the assembly seat 61 and make the plow blade 5 slide to the required use height in the assembly seat 61. Then release the push rods 68, and use the restoring force of the first spring 65 to drive the two groups of transmission blocks 64 to slide back on the guide rods 63, and the transmission blocks 64 synchronously drive the insertion blocks 66 to slide into the slots 67, so as to achieve the purpose of replacing or installing the plow blade 5. Then, move the laying ship driving frame 1 on the seabed, and make the plow blade 5 dig a trench on the seabed ground. Then, drive the wire reel 2 to rotate by the motor 3, so that one end of the submarine cable on the wire reel 2 passes through the wire port 4 and is buried in the trench dug by the plow blade 5. When there are stones on the forward route of the frame 1, the protection plate 73 contacts the stones, and the stones hit the protection plate 73, and the protection plate 73 drives the slide rod 72 to slide in the chute 71, so that the impact force received by the protection plate 73 continuously acts on the second spring 74, and the elastic force of the second spring 74 is used to buffer the impact force on the protection plate 73, and the crushed stones fall along the inclined surface of the protection plate 73 to both sides of the frame 1, so as not to affect the forward route of the frame 1 and the laying progress of the submarine cable.
