Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a cable for an artificial intelligence underwater robot. Background Technology

[0002] The underwater robot cable, also known as the umbilical cable, is a key component connecting the underwater robot to the surface control platform. It is mainly responsible for transmitting power, control signals, and data.

[0003] Underwater robot cables can be classified into zero-buoyancy cables and negative-buoyancy cables according to their buoyancy characteristics. Zero-buoyancy cables use polyurethane foam as a sheath to make the overall density of the cable close to that of water. However, the cable consists of a conductor layer, an insulation layer, a shielding layer, a buoyancy regulating layer, a filling buffer layer, and a polyethylene protective sheath. Except for the buoyancy regulating layer and the filling buffer layer, which have a lower density than water, the density of the rest of the cable is greater than that of water. Therefore, in order to make the overall density of the underwater robot cable the same as that of water, the buoyancy regulating layer is often thicker. This results in a larger cross-section of the underwater robot cable. As a result, when the underwater robot turns underwater or when the cable is bent, the resistance generated by the bending change can hinder the movement of the underwater robot. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an artificial intelligence underwater robot cable, which has the advantage of setting buoyancy points in sections within the cable, thus avoiding the problem of the large cross-section of the underwater robot cable causing movement obstacles.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: An artificial intelligence underwater robot cable includes a cable body with node airbags evenly distributed on the cable body. The node airbags are wrapped around the outside of the cable body, and there is a gap between the node airbags and the cable body. Connecting joints are fixedly installed at both ends of the node airbags. An inflation mechanism for inflating the node airbags is installed on the cable body.

[0006] A further solution is that the outer wall of the node airbag has two layers, with a mesh-like elastic metal mesh sandwiched between the two layers. Multiple branch lines are evenly distributed circumferentially inside the cable body. An insulating protective layer is set on the outside of the branch lines. The cable body is cut at the point where it wraps around the branch lines at the node airbag. The cable inside has a bent section, and a wire fixing ring is set at the bend. The wire fixing ring has a corresponding groove for each branch line, which can be used to lock the branch lines inside the groove.

[0007] A further embodiment is that the inflation mechanism includes an inflation tube, with both ends of the inflation tube inserted into the positions of the two node airbags, and the inflation tube inserted into the middle position of the cable body.

[0008] A further embodiment involves installing a shut-off rod at the junction of the two inflation tubes inside the node airbag. The shut-off rod is hollow, and its two ends are connected to the two adjacent inflation tubes. Two inflation slots are symmetrically formed on the side wall of the shut-off rod at its middle position. An inflation partition is slidably connected in the inflation slot, and an inflation spring is installed at the opposite ends of the two inflation partitions. An inflation hole communicating with the inflation slot is opened on the side wall of the shut-off rod near the center.

[0009] A further option is to provide a tension spring at the end of the inflation tube, with the other end of the tension spring fixedly installed at the end of the air-closing rod.

[0010] A further embodiment is that the inflation mechanism includes an inflation tube two, which is located on the outside of the cable body. The cable body is equipped with an inflation joint at the middle position of the node airbag, and the inflation joint has an inflation port.

[0011] A further design is to make the side of the inflation port closest to the central axis of the cable body tapered and place an air-blocking bead at this position, while an air-blocking spring is fixedly installed on the side of the inflation port away from the central axis of the cable body. During inflation, the gas will push open the air-blocking bead and inflate the node airbag.

[0012] A further embodiment is that the connecting section includes an inner cylinder and an outer cylinder, the inner cylinder is fixedly connected to the cable body, the outer cylinder is slidably sleeved on the inner cylinder, the front and rear ends of the inner cylinder are machined with protrusions to restrict the movement of the outer cylinder, and the inner side of the outer cylinder is evenly distributed with sealing rubber strips.

[0013] A further embodiment includes a magnetic venting mechanism in the connecting joint. This mechanism comprises a magnetic coil disposed within the connecting joint, with a magnetic slip ring inside the coil. A venting groove is formed in the connecting joint, and the magnetic slip ring slides along the axial direction of the cable body into the venting groove. An external venting groove, communicating with the node air bladder, is formed. The magnetic slip ring blocks the venting groove. The venting groove communicates with the air storage chamber. A venting spring, specifically a tension spring, is positioned between the magnetic slip ring and the end of the venting groove. (III) Beneficial Effects Compared with the prior art, the present invention provides an artificial intelligence underwater robot cable, which has the following beneficial effects: This AI-powered underwater robot cable inflates the node air bladders via an inflation mechanism. By controlling the air pressure, a specific volume of gas is filled into the node air bladders, giving them buoyancy and causing the cable itself to float. This technical solution avoids the need for a thick, low-density buoyancy adjustment layer inside the cable, making it easier to bend and thus facilitating the movement of the intelligent underwater robot. In water environments of varying densities, different volumes of gas can be added to the node air bladders to adapt to different water densities.

[0014] When the node airbag of this AI underwater robot is inflated, the node airbag will bulge outwards, and at the same time, the two sides of the node airbag will not be constrained when they contract inwards. This is more in line with the stress characteristics of rubber materials and can effectively improve the service life of the node airbag.

[0015] The cable for this AI-powered underwater robot uses a magnetic induction coil connected to the wires within the cable body. This coil attracts a magnetic slip ring to block the air vent. Simultaneously, a venting spring (a tension spring) is installed between the magnetic slip ring and the end of the venting slot. In the event of a cable breakage, the tension of the venting spring opens the air vent, allowing high-pressure gas from the storage chamber to enter the node air bladder. This causes the node air bladder to rapidly expand, making it float on the water surface, facilitating search and preventing the underwater robot from being lost. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] In addition, a fixed connection refers to a connection in which parts or components are fixed and there is no relative movement; a transmission connection refers to a connection in which mechanical motion or torque is transmitted to other working parts through a transmission component; a sliding connection refers to a connection in which two objects are in contact but not fixed and can slide relative to each other; and a rotational connection refers to a connection in which two objects are in contact but not fixed and can rotate relative to each other.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Zero-buoyancy cables have a density close to that of water, allowing robots to operate without consuming additional power to counteract the cable's weight. Furthermore, because their density is similar to water, they don't drag on the surface, reducing the risk of the cable getting caught or tangled in underwater obstacles. However, traditional zero-buoyancy cables have a larger cross-section due to the added buoyancy adjustment layer. When underwater robots turn or the cable tugs, the significant resistance generated during bending hinders the robot's movement. Additionally, traditional zero-buoyancy cables are only suitable for one type of water density, requiring different models for environments with varying water densities. They are not well-suited for narrow, winding underwater environments such as rivers and lakes.

[0023] Example 1: Based on this, such as Figures 1 to 8 As shown, the present invention provides an artificial intelligence underwater robot cable, including a cable body 1, on which node airbags 2 are evenly distributed, the node airbags 2 are wrapped around the outside of the cable body 1, there is a gap between the node airbags 2 and the cable body 1, the two ends of the node airbags 2 are fixedly installed with connecting joints 3, and the cable body 1 is equipped with an inflation mechanism 4 that can inflate the node airbags 2.

[0024] During the operation of the aforementioned intelligent underwater robot cable, after the intelligent underwater robot is released, air is inflated into the node airbag 2 via the inflation mechanism 4. By controlling the air pressure, a specific volume of gas is filled into the node airbag 2, giving it buoyancy and causing the cable body 1 to float. This technical solution avoids the need for a thick, low-density buoyancy adjustment layer inside the cable, making the cable easier to bend and thus facilitating the movement of the intelligent underwater robot. In water environments of different densities, different volumes of gas can be inflated into the node airbag 2 to adapt to different water densities. Figure 2 , Figure 3 and Figure 4As shown, the outer wall of the node airbag 2 has two layers, with a mesh-like elastic metal mesh 21 sandwiched between them. The elastic metal mesh 21 can enhance the strength of the node airbag 2 and also serve as a shielding layer, improving the anti-interference capability of the cable body 1. Multiple branch lines 11 are evenly distributed circumferentially inside the cable body 1. An insulating protective layer is provided on the outside of each branch line 11. The cable body 1 is cut at the point where it wraps around the branch lines 11 within the node airbag 2. The cable inside has a bent section, and a fixing ring 12 is provided at the bend. The fixing ring 12 has corresponding grooves for each branch line 11, which can hold the branch lines 11 inside. Thus, if the underwater robot encounters a heavy foreign object while moving underwater, the node airbag 2 can act as a buffer, and the regular bending of the branch lines 11 can reduce the direct stretching and damage to the cable body 1 and branch lines 11. Figure 3 and Figure 4 As shown, during the inflation process of the node airbag 2 using the inflation mechanism 4, the inflation mechanism 4 includes an inflation tube 41. Both ends of the inflation tube 41 are inserted into the positions of the two node airbags 2, respectively. The inflation tube 41 is inserted into the middle position of the cable body 1. During inflation, the inflation tube 41 of the cable body 1 can be connected to an external air pump, which will then pump gas at a specific pressure into the node airbag 2. An air-sealing rod 42 is provided at the node of the two inflation tubes 41 inside the node airbag 2. The air-sealing rod 42 is hollow, and both ends are connected to the two adjacent inflation tubes 41. Two inflation grooves 421 are symmetrically opened on the side wall at the middle position of the air-sealing rod 42. An inflation partition 422 is slidably connected in the inflation groove 421. The two inflation partitions 422... An inflation spring 423 is provided at the opposite end of the air-sealing rod 42. An inflation hole 424 communicating with the inflation groove 421 is opened on the side wall of the air-sealing rod 42 near the center. When gas enters the air-sealing rod 42, the air pressure will exert pressure on the inflation partition 422, and the inflation partition 422 will exert pressure on the inflation partition 422, thereby compressing the inflation spring 423. When the inflation partition 422 no longer obstructs the inflation hole 424, air will enter the node airbag 2 from the inflation hole 424. At the same time, a tension spring 425 is sleeved on the end of the inflation tube 41. The other end of the tension spring 425 is fixedly installed on the end of the air-sealing rod 42, so that the inflation tube 41 can be tightened, thereby positioning the inflation tube 41 in the middle of the cable body 1 and preventing the inflation tube 41 from getting tangled with other branch wires 11.

[0025] Example 2: like Figures 5 to 8As shown, the inflation mechanism 4 includes an inflation tube 43 located on the outside of the cable body 1. An inflation joint 5 is installed in the middle of the node air bladder 2 on the cable body 1. An inflation port 51 is provided on the inflation joint 5. During inflation, gas enters the inflation joint 5 from the inflation tube 43 and then enters the node air bladder 2 through the inflation port 51. The side of the inflation port 51 closest to the central axis of the cable body 1 is tapered, and an air-blocking bead 52 is placed at this position. An air-blocking spring 53 is fixedly installed on the side of the inflation port 51 away from the central axis of the cable body 1. During inflation, gas will force open the air-blocking bead 52 and inflate the node air bladder 2. The air-blocking bead 52 can... To effectively prevent air backflow, the node airbag 2 is made of flexible rubber material. During inflation, the node airbag 2 contracts towards the center. To better suit the stress characteristics of rubber material and thus enhance durability, the connecting joint 3 includes an inner cylinder 31 and an outer cylinder 32. The inner cylinder 31 is fixedly connected to the cable body 1, and the outer cylinder 32 is slidably fitted onto the inner cylinder 31. The front and rear ends of the inner cylinder 31 have protrusions to restrict the movement of the outer cylinder 32. Sealing rubber strips are evenly distributed on the inner surface of the outer cylinder 32. Thus, during inflation, the node airbag 2 bulges outwards, while its sides contract inwards without being subjected to pressure. The connecting joint 3, away from the node airbag 2, has an air storage chamber 33. A magnetic induction venting mechanism 6 is provided in the connecting joint 3. The magnetic induction venting mechanism 6 includes a magnetic coil 61, which is disposed in the connecting joint 3. A magnetic slip ring 62 is disposed inside the magnetic coil 61. A venting groove 34 is provided in the connecting joint 3. The magnetic slip ring 62 is slidably connected to the venting groove 34 along the axial direction of the cable body 1. A venting groove 35 communicating with the node airbag 2 is provided on the outside of the venting groove 34. The magnetic slip ring 62 blocks the venting groove 35. The venting groove 34 communicates with the air storage chamber 33. (The remaining text appears to be unrelated and possibly machine-generated: "boats and their propellers in rivers and lakes, waste generated during river construction, and river channels...") Rocks at the bottom could damage the cable itself, and if the cable breaks, the underwater robot could be lost, causing significant losses. The magnetic coil 61 is powered by wires in the cable body 1. The magnetic coil 61 attracts the magnetic slip ring 62 to block the ventilation groove 35. At the same time, a ventilation spring 63 is provided between the magnetic slip ring 62 and the end of the venting groove 34. The ventilation spring 63 is a tension spring. If the cable body 1 breaks, the ventilation groove 35 will open under the tension of the ventilation spring 63, and the high-pressure gas in the air storage chamber 33 will enter the node airbag 2, causing the node airbag 2 to expand rapidly and float on the water surface, thus facilitating personnel search.

[0026] Working principle: After the intelligent underwater robot is deployed, air is inflated into the node airbag 2 via the inflation mechanism 4. By controlling the air pressure, a specific volume of gas is filled into the node airbag 2, giving it buoyancy and thus causing the cable body 1 to float. Figure 2 , Figure 3 and Figure 4 As shown, a mesh-like elastic metal mesh 21 is nested between the two layers. The elastic metal mesh 21 can enhance the strength of the node airbag 2 and also serve as a shielding layer, improving the anti-interference capability of the cable body 1. The internal branch wires 11 have bent sections, and a fixing ring 12 is provided at the bend. The fixing ring 12 has corresponding grooves for the branch wires 11, which can hold the branch wires 11 inside the grooves. Thus, if the underwater robot encounters a heavy foreign object while moving underwater, the node airbag 2 can act as a buffer, and the regular bending of the branch wires 11 can reduce the direct stretching and damage to the cable body 1 and branch wires 11. Figure 3 and Figure 4 As shown, during the inflation process of the inflation mechanism 4 into the node airbag 2, the inflation mechanism 4 includes an inflation tube 41. Both ends of the inflation tube 41 are inserted into the positions of the two node airbags 2, respectively. The inflation tube 41 is inserted into the middle position of the cable body 1. During inflation, the inflation tube 41 of the cable body 1 can be connected to an external air pump, which will then pump gas at a specific pressure into the node airbag 2. An air-sealing rod 42 is installed at the node of the two inflation tubes 41 inside the node airbag 2. The air-sealing rod 42 is hollow, and both ends are connected to the two adjacent inflation tubes 41. Two symmetrical openings are formed on the side wall of the middle position of the air-sealing rod 42. An inflation slot 421 is provided, and an inflation partition 422 is slidably connected in the inflation slot 421. An inflation spring 423 is provided at the opposite ends of the two inflation partitions 422. An inflation hole 424 communicating with the inflation slot 421 is opened on the side wall of the air-closing rod 42 near the center. When gas enters the air-closing rod 42, the air pressure will exert pressure on the inflation partition 422, thereby compressing the inflation spring 423. When the inflation partition 422 no longer obstructs the inflation hole 424, air will enter the node airbag 2 through the inflation hole 424. At the same time, a tension spring 425 is sleeved on the end of the inflation tube 41, and the other end of the tension spring 425 is fixedly installed on the end of the air-closing rod 42.
