Description

Technical Field

[0001] This utility model relates to the field of submarine cable laying, and in particular to a rotary plow blade for laying cables. Background Technology

[0002] Submarine cable laying plows are mainly used in the submarine laying of telecommunications and power cables, and are used to dig trenches on the seabed during cable laying. Existing submarine cable laying plow blades are typically inclined structures with a set angle. For example, the State Intellectual Property Office of China disclosed a deep-water laying plow with strong cutting capability for submarine cables and its blade mechanism on September 29, 2023, publication number CN116815855A. This deep-water burial plow with high cutting power for submarine cables and its plowing mechanism include a plow frame, a first plow blade, a second plow blade, a first plowshare, and a second plowshare. The plow frame has a mounting section, which includes a first straight inclined section and a second straight inclined section, which are staggered. The first plow blade is mounted on the first straight inclined section of the mounting section, and the second plow blade is mounted on the second straight inclined section of the mounting section. The first plowshare is located at the bottom of the first plow blade, adjacent to the first and second plow blades. The second plowshare is located at the bottom of the second plow blade, on the opposite side of the adjacent sides of the first and second plow blades. Although this deep-water burial plow with high cutting power for submarine cables and its plowing mechanism can increase the depth of seabed trench excavation, it is not convenient to switch the excavation angle in time when encountering hard obstacles during the excavation process, which may lead to damage to the plow blades.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] This embodiment provides a rotary plow blade for embedding a plow, including a wheel frame 100, an eccentric wheel 200, a plow blade body 300, and a connecting rod 400; the eccentric wheel 200 is eccentrically disposed near the center of the wheel frame 100; the plow blade body 300 is an integral structure including a blade head 301, a blade shank 302, and a curved portion 303; the blade head 301 and the blade shank 302 are disposed at both ends of the curved portion 303; the end of the blade shank 302 is axially connected to the outer periphery of the wheel frame 100; one end of the connecting rod 400 is axially connected to the outer periphery of the eccentric wheel 200, and the other end is axially connected to the curved portion 303. Those skilled in the art will understand that the distance between the eccentric wheel 200 and the outer periphery of the wheel frame 100 can be periodically changed as the wheel frame 100 rotates. When the plow blade 300 rotates to the position where the eccentric wheel 200 and the outer periphery of the wheel frame 100 have the minimum distance, the blade head 301 of the plow blade 300 extends to the maximum extent beyond the outer periphery of the wheel frame 100; when the plow blade 300 rotates to the position where the eccentric wheel 200 and the outer periphery of the wheel frame 100 have the maximum distance, the blade head 301 retracts to the maximum extent. The blade head 301 retracts into the outer periphery of the wheel frame 100; thus, the blade head 301 can periodically extend and retract along the outer periphery of the wheel frame 100 as the wheel frame 100 rotates; at the same time, when the eccentric wheel 200 has the minimum distance from the outer periphery of the wheel frame 100, the eccentric wheel 200 also has the minimum distance from the excavation surface. Thus, the rotary plow blade of the burial plow provided in this embodiment can have the maximum excavation force and depth during excavation, and the excavation force, excavation depth and excavation angle can be adjusted as needed by rotating the wheel frame 100.

[0021] Furthermore, the rotary plow blade for burying plows provided in this embodiment also includes a connecting seat 500 and a first screw 601. The connecting seat 500 is fixed to the outer periphery of the wheel frame 100. The inner side edge of the connecting seat 500 is provided with a pair of connecting ears 502 having a first connecting hole 501. The end of the blade shank 302 is provided with a connecting ring 305 having a second connecting hole 304. The connecting ring 305 is sandwiched between the pair of connecting ears 502 and is axially connected to the connecting ears 502 by the first screw 601. Those skilled in the art will understand that the connecting seat 500 enables the end shaft of the blade shank 302 to be axially connected to the outer periphery of the wheel frame 100; the connecting seat 500 can be welded to the outer periphery of the wheel frame 100, or it can be an integral structure with the wheel frame 100; preferably, in the rotary plow blade of the burial plow provided in this embodiment, the outer periphery of the wheel frame 100 is provided with a third connecting hole 101; the connecting seat 500 is provided with a fourth connecting hole 503, and the connecting seat 500 is locked to the outer periphery of the wheel frame 100 by a second screw 504. Those skilled in the art will understand that this facilitates the disassembly and maintenance of the rotary plow blade of the burial plow provided in this embodiment.

[0022] Furthermore, the curved portion 303 of the plowshare body 300 is provided with a fifth connecting hole 306; the connecting rod 400 is provided with a first connecting post 401 at one end near the plowshare body 300; the first connecting post 401 is inserted into the fifth connecting hole 306; the connecting rod 400 is provided with a sixth connecting hole 402 at one end near the eccentric wheel 200, and a second connecting post 201 is provided along the outer periphery of the eccentric wheel 200, the second connecting post 201 being inserted into the sixth connecting hole 402. Those skilled in the art will understand that the curved portion 303 and the connecting rod 400 are axially connected via the first connecting post 401 and the fifth connecting hole 306; the eccentric wheel 200 and the connecting rod 400 are axially connected via the second connecting post 201 and the sixth connecting hole 402.

[0023] Furthermore, the rotary plow blade of the burial plow provided in this embodiment also includes a center screw 102; the eccentric wheel 200 includes an outer wheel body 202 and an inner wheel body 203, and the second connecting post 201 is disposed on the outer periphery of the outer side of the outer wheel body 202; a circular groove 204 is provided on the inner side of the outer wheel body 202, and the inner wheel body 203 is fixed in the circular groove 204; a first eccentric connecting hole 205 is provided on the inner wheel body 203; a second eccentric connecting hole 206 is provided on the outer wheel body 202; a center connecting hole is provided at the center of the wheel frame 100; the inner wheel body 203, the outer wheel body 202 and the wheel frame 100 are locked together by the center screw 102, the center connecting hole, the first eccentric connecting hole 205 and the second eccentric connecting hole 206. Those skilled in the art will understand that when the wheel frame 100 rotates, it drives the inner wheel 203 and outer wheel 202 to rotate eccentrically, thereby causing the plow blade 300 to periodically extend and reciprocate during rotation. This achieves maximum digging force and depth during excavation, and allows adjustment of digging force, depth, and angle as needed by rotating the wheel frame 100. Those skilled in the art will also understand that the inner wheel 203 and outer wheel 202 can be manufactured as a single unit, thereby reducing manufacturing complexity and delivery costs.

[0024] Furthermore, the wheel frame 100 includes a first frame 103 and a second frame 104; the first frame 103 has a first central connecting hole 105 at its center; the second frame 104 has a second central connecting hole 106 at its center; the first central connecting hole 105 is a hexagonal through hole; the second central connecting hole 106 is a circular through hole; the central screw 102 includes a body and a cap, the body being cylindrical; the cap being a hexagonal columnar shape; the body of the central screw 102 passes through the second central connecting hole 106, the first eccentric connecting hole 205, and the second eccentric connecting hole 206; the cap of the central screw 102 is engaged in the first central connecting hole 105. Those skilled in the art will understand that the above structure can sequentially connect the first frame 103, the second frame 104, the inner wheel 203, and the outer wheel 202, so that when the first frame 103 is driven to rotate, the second frame 104, the inner wheel 203, and the outer wheel 202 are driven to rotate with the first frame 103, thereby driving the plow body 300 to periodically extend and retract while rotating.

[0025] Furthermore, the end of the cutter head 301 is toothed. Those skilled in the art will understand that setting the cutter head 301 to be toothed makes it more advantageous for the cutter head to penetrate deeper into the excavation face.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
