Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a dynamic water surface floating cable. Background Art

[0002] A cable is a tool composed of multiple wires for transmitting electrical energy or electrical signals. With the continuous progress of society, the range of electrical signal transmission is getting wider and wider, and cables have become an indispensable part of our lives. In waters such as oceans and rivers, due to the rapid development, mechanical equipment is needed, and thus cables are also required for power supply and communication.

[0003] During the installation and laying of cables, most of the cables used in engineering equipment are of conventional types and do not have the physical characteristic of floating on the water surface. When the cable is laid in water, the cable cannot float on the water surface. The pulling force generated by the self-weight of the cable in water will increase the burden on the engineering equipment, and it is easy to cause the connection part between the cable and the equipment to fall off. During the process of pulling the cable, debris in the water will also damage the cable outer skin, thereby reducing the safety of the cable during underwater operations. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a dynamic water surface floating cable. By connecting floating bodies that can be lifted and lowered on both sides of the connecting frame, the cable can float on the water surface, overcoming the deficiency that the prior art cables cannot float, and aiming to solve the problems in the background art.

[0005] To achieve the above technical purpose, the specific technical solution of the present invention is as follows. A dynamic water surface floating cable proposed by the present invention includes: a floating component, which is evenly distributed along the length direction of the cable; the floating component includes a connecting frame, and a pair of floating bodies that can be lifted and lowered are connected to both sides of the connecting frame. An elevating frame is connected to the floating body; a threaded rod is rotatably connected to the elevating frame, and a threaded sleeve threadedly connected to the threaded rod is rotatably connected to the connecting frame. A gear is fixedly connected to the surface of the threaded sleeve, and when the gear rotates, it drives the elevating frame to rise and fall; the connecting frame is movably connected with a push rod, one end of the push rod is fixedly connected with a ferrule assembly for fixing the cable, and a bracket is fixedly connected to the push rod. A rack meshing with the gear is fixedly connected to the bracket.

[0006] As a preferred technical solution of the present invention, a fixing frame is fixedly connected to the connecting frame, baffles are fixedly connected to both ends of the fixing frame, a slider is slidably connected to the fixing frame, a tension spring is fixedly connected between the slider and the baffle, and a connecting rod is hinged between the slider and the push rod.

[0007] As a preferred technical solution of the present invention, the elevating frame is provided with a vertical sliding hole, a lifting block is slidably connected in the sliding hole, a fixing rod is fixedly connected to the lifting block, one end of the fixing rod is fixedly connected to the floating body, and a screw rod is rotatably connected in the sliding hole and threadedly connected to the lifting block.

[0008] As a preferred technical solution of the present invention, the ferrule assembly includes a first clamping plate and a second clamping plate. The second clamping plate is rotatably connected to the first clamping plate, and a through hole is formed between the first clamping plate and the second clamping plate, and the cable is fixed in the through hole.

[0009] As a preferred technical solution of the present invention, a clamping hole is provided on the first clamping plate, and a clamping block that engages with the clamping hole is provided on the second clamping plate.

[0010] As a preferred technical solution of the present invention, a pair of fixed brackets are symmetrically and fixedly connected to the connecting frame. The two fixed brackets are respectively arranged on both sides of the push rod, and the end of the fixed bracket is rotatably connected to a limiting wheel for limiting the cable. A limiting groove is provided on the circumferential surface of the limiting wheel.

[0011] As a preferred technical solution of the present invention, a guide rod is fixedly connected to the lifting frame, and the guide rod is movably connected to the connecting frame.

[0012] As a preferred technical solution of the present invention, a slide rail for sliding connection with the slider is provided on the fixed frame, and the floating body has a rectangular block structure.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. By connecting multiple floating components to the cable in the present invention, the cable can float near the water surface, solving the problem that the cable sinks to the bottom of the water under gravity and causing damage, and playing a protective role for the cable.

[0015] 2. The floating component of the present invention is provided with a liftable floating body and a push rod. When encountering strong winds and waves, the pulling force of the cable itself increases, driving the push rod to move on the connecting frame. When the push rod moves, it drives the lifting frame to rise, and then drives the floating body to rise, so that the cable descends below the water surface, thereby reducing the impact and shaking of the wind and waves on the cable and protecting the cable.

[0016] 3. By connecting a slider and a tension spring to the fixed frame in the present invention, when the wind and waves are small, under the pulling force of the tension spring, the part of the cable connected to the ferrule assembly is bent; when the wind and waves are large, the cable drives the push rod to move, and when the push rod moves, it drives the slider to move, so that the part of the cable connected to the ferrule assembly is straightened, achieving the effect of paying out the cable, increasing the length of the cable, and at the same time achieving the effect of buffering the cable and avoiding excessive pulling force of the cable.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Embodiment: This embodiment discloses a dynamic water surface floating cable. As Figures 1-6 shown, it includes: a floating component 2, which is evenly distributed along the length direction of the cable 1. Through the floating component 2, the cable 1 can float on the water surface, avoiding the cable 1 from sinking to the bottom of the water and protecting the cable 1.

[0026] As Figures 2-3As shown, the floating component 2 includes a connecting frame 3. The connecting frame 3 is in a T shape. A pair of liftable floating bodies 4 are connected to both sides of the connecting frame 3. The floating bodies 4 are in a rectangular block structure to maintain the stability of the entire floating component 2. A lifting frame 41 is connected to the floating body 4. When the lifting frame 41 lifts or lowers, it can drive the floating body 4 to lift or lower. By the lifting and lowering of the floating body 4, the depth of the cable 1 in the horizontal direction can be adjusted. Among them, a threaded rod 42 is rotatably connected to the lifting frame 41. The threaded rod 42 penetrates through the connecting frame 3. A threaded sleeve 44 that is threadedly connected to the threaded rod 42 is rotatably connected to the connecting frame 3. A gear 43 is fixedly connected to the surface of the threaded sleeve 44. And a guide rod 45 is fixedly connected to the lifting frame 41. The guide rod 45 is movably connected to the connecting frame 3, so that the lifting frame 41 only makes lifting and lowering movements. When the gear 43 rotates, it drives the lifting frame 41 to lift or lower, and then drives the floating body 4 to lift or lower.

[0027] Further, the connecting frame 3 is movably connected with a push rod 5. One end of the push rod 5 is fixedly connected with a ferrule assembly 6 for fixing the cable 1. And a pair of brackets 51 are symmetrically and fixedly connected to the push rod 5. A rack 52 that meshes with the gear 43 is fixedly connected to the brackets 51. When the push rod 5 moves horizontally on the connecting frame 3, it drives the rack 52 to move. When the rack 52 moves, it drives the gear 43 to rotate. The gear 43 drives the threaded sleeve 44 to rotate, and then drives the threaded rod 42 to lift or lower. The threaded rod 42 drives the lifting frame 41 to lift or lower, and the lifting frame 41 drives the floating body 4 to lift or lower to adjust the height of the floating body 4. When there are wind and waves on the water surface, the wind and waves drive the cable 1 to move, and the self-tension of the cable 1 increases. The cable 1 drives the push rod 5 to move away from the fixed frame 7. The push rod 5 drives the rack 52 to move, and then drives the floating body 4 to rise, increasing the vertical distance between the floating body 4 and the cable 1. Then the cable 1 descends below the water surface, reducing the impact of the wind and waves on the cable 1 and protecting the cable 1.

[0028] As Figure 4 shown, a fixed frame 7 is fixedly connected to the connecting frame 3. The fixed frame 7 is perpendicular to the push rod 5. Baffles 72 are fixedly connected to both ends of the fixed frame 7. And a slider 71 is slidably connected to the fixed frame 7. A slide rail 74 for slidably connecting the slider 71 is provided on the fixed frame 7. The slide rail 74 is horizontally arranged. A tension spring 73 is fixedly connected between the slider 71 and the baffle 72. The tension spring 73 exerts a pulling force on the slider 71. And a connecting rod 8 is hinged between the slider 71 and the push rod 5. In the normal state of the tension spring 73, the push rod 5 is in a position close to the fixed frame 7. The part of the cable 1 connected to the ferrule assembly 6 is in an arc shape. When there are wind and waves on the water surface, the tension of the cable 1 increases, driving the push rod 5 to move away from the fixed frame 7, driving the two sliders 71 to approach each other. The tension spring 73 is stretched and becomes longer. The part of the cable 1 connected to the ferrule assembly 6 is straightened, increasing the length of the cable 1 and reducing the self-tension of the cable 1. Secondly, the push rod 5 moves on the connecting frame 3, playing a buffering role for the cable 1.

[0029] Furthermore, a pair of fixed brackets 31 are symmetrically and fixedly connected to the connecting bracket 3. The two fixed brackets 31 are respectively arranged on both sides of the push rod 5, and the end of the fixed bracket 31 is rotatably connected with a limiting wheel 32 for limiting the cable 1. The circumferential surface of the limiting wheel 32 is provided with a limiting groove to prevent the cable 1 from separating from the limiting wheel 32. The cable 1 is limited by the two limiting wheels 32. In the normal state, the part of the cable 1 connected to the ferrule assembly 6 is in an arc shape.

[0030] As Figure 5 shown, the lifting frame 41 is provided with a vertical sliding hole 46. A lifting block 48 is slidably connected in the sliding hole 46. The lifting block 48 is fixedly connected with a fixed rod 49. One end of the fixed rod 49 is fixedly connected with the floating body 4. And a screw rod 47 is rotatably connected in the sliding hole 46. The screw rod 47 is threadedly connected with the lifting block 48. The lower end of the screw rod 47 is a hexagonal rotating part, which is convenient for rotating the screw rod 47. By manually rotating the screw rod 47, the lifting block 48 is driven to lift, and then the floating body 4 is driven to lift, so as to adjust the height of the floating body 4 relative to the connecting bracket 3.

[0031] As Figure 6 shown, the ferrule assembly 6 includes a first clamping plate 61 and a second clamping plate 62. The first clamping plate 61 is fixedly connected with the push rod 5. The second clamping plate 62 is rotatably connected with the first clamping plate 61. And a through hole 63 is formed between the first clamping plate 61 and the second clamping plate 62. The size of the through hole 63 is the same as that of the cable 1. The cable 1 is fixed in the through hole 63. A clamping hole 64 is provided on the first clamping plate 61. A clamping block 65 engaged with the clamping hole 64 is provided on the second clamping plate 62. By rotating the second clamping plate 62, the clamping block 65 is stuck in the clamping hole 64, so as to clamp and fix the cable 1, which is convenient for the installation and disassembly of the floating assembly 2.

[0032] Working principle: In the present invention, a plurality of floating assemblies 2 are evenly installed on the cable 1, so that the cable 1 can float on the water surface. And when the cable 1 encounters strong winds and waves, the self-tension of the cable 1 increases. The cable 1 drives the push rod 5 to move away from the fixed frame 7. The push rod 5 drives the rack 52 to move, and then drives the floating body 4 to rise, increasing the vertical distance between the floating body 4 and the cable 1. Then the cable 1 descends below the water surface, reducing the impact of the wind and waves on the cable 1 and protecting the cable 1. At the same time, the part of the cable 1 connected to the ferrule assembly 6 changes from an arc shape to a straight shape, achieving the effect of paying out the cable 1, increasing the length of the cable 1, reducing the self-tension of the cable 1, and playing a buffering role for the cable 1 to protect the cable 1.

[0033] Finally, it should be noted that in the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.
