Description

Technical Field

[0001] This utility model relates to the technical field of cable products, and in particular to a floating luminescent cable. Background Technology

[0002] With increasing environmental awareness, ecological aquaculture has become a new model in the aquaculture industry, and light-based insect-attracting fish farming is a commonly used method. Currently, farmers use electric lights suspended by wires along the shore and in the water for this purpose. However, when setting up multiple points in large bodies of water, problems arise such as limited light sources, unsightly installation of ordinary cables, obstruction of net fishing, potential electrical leakage hazards, and the inability to emit light, leading to fish aggregation and negatively impacting aquaculture efficiency.

[0003] To overcome the aforementioned problems, we have invented a floating luminous cable. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing fish farming methods that use wires to suspend lights on the shore and in the water, which have limitations in the number of light sources, affect aesthetics, hinder net fishing, pose a safety hazard of electric leakage, and cause fish to gather, thus affecting the farming effect. The specific solution is as follows:

[0005] A floating luminescent cable is provided. The cable is in the shape of a flat strip and includes a first conductor and a second conductor that are separated from each other. An insulator is used to separate and wrap the first conductor and the second conductor. The cross-section of the insulator is dumbbell-shaped. An air bladder is provided in the upper and lower spaces of the insulator. A protective layer is wrapped around the insulator and the two air bladders. The protective layer contains a luminescent element. A water-blocking layer is wrapped around the protective layer.

[0006] Furthermore, the first conductor and the second conductor have the same structure, including multiple core wires, which are made of aluminum alloy wire.

[0007] Furthermore, the density of the first conductor and the second conductor is 2.71 g·cm³. -3 .

[0008] Furthermore, the density of the insulator is 0.95 g·cm³. -3 .

[0009] Furthermore, the density of the protective layer is 1.0 g·cm³. -3 .

[0010] Furthermore, the density of the water-blocking layer is 1.2 g·cm³. -3 .

[0011] Furthermore, the spatial size of the two airbags ensures that the overall cable density does not exceed 0.90 g·cm³.-3 .

[0012] Furthermore, the insulator is cross-linked polyethylene insulation material.

[0013] Furthermore, the protective layer is made of medium-density polyethylene, and the luminescent material is ultrafine red energy-storing phosphorescent powder, which is added to the protective layer.

[0014] Furthermore, the water-blocking layer is a transparent polyether-type polyurethane material.

[0015] In summary, the technical solution of this utility model has the following beneficial effects:

[0016] This invention solves the problems of existing fish farming methods that use wired lights suspended from the shore and in the water, which have limitations in the number of light sources, affect aesthetics, hinder net fishing, pose a safety hazard of electric leakage, and fail to emit light, leading to fish aggregation and affecting farming results. This solution employs a special structure and has the following advantages:

[0017] (1) It solves the problem of limited number and uneven distribution of light sources in light-induced insect breeding. The self-luminous cable turns the point light source into a line light source, making the fish distribution more even.

[0018] (2) It has water-resistant and waterproof properties, meets the requirements for long-term use in water, improves the safety of use, and avoids the risk of electric leakage.

[0019] (3) The cable can float on the water surface and serves as a warning line. It floats on the water surface and does not affect production activities such as net fishing.

[0020] (4) The light-emitting body can store energy and emit light on its own, providing a light source for attracting insects and raising fish with light, reducing the cost and trouble of setting up additional light sources.

[0021] (5) The cable is equipped with two sets of conductors, one set is connected to the AC live wire and the other set is connected to the AC neutral wire, which also has the function of transmitting AC power, making it convenient for farmers to use electricity outdoors.

[0022] (6) The special dumbbell-shaped structure of the insulator has multiple advantages, such as maintaining a fixed safe distance between the AC live wire and the neutral wire and providing insulation, while also freeing up space for the upper and lower airbags.

[0023] (7) The cable structure is symmetrical, simple, compact, easy to process, and has low material cost. Its multi-purpose nature helps to reduce the investment of farmers. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] like Figure 1 As shown, a floating luminescent cable 1 is a flat ribbon-shaped cable comprising a first conductor 11 and a second conductor 12 separated from each other. An insulator 2 separates and wraps the first conductor 11 and the second conductor 12. The insulator 2 has a dumbbell-shaped cross-section. An air bladder 5 is located in the upper and lower spaces of the insulator 2. A protective layer 3 surrounds the insulator 2 and the two air bladders 5, containing a luminescent element 31. A water-blocking layer 4 surrounds the protective layer 3. The first conductor 11 and the second conductor 12 transmit electrical energy; for example, the first conductor 11 is connected to the AC live wire, and the second conductor 12 is connected to the AC neutral wire. The insulator 2 ensures safe power transmission, the protective layer 3 protects the internal structure, the water-blocking layer 4 prevents water penetration, the air bladders 5 make the cable 1 float, and the luminescent element 31 enables the cable 1 to emit light.

[0030] Specifically, the first conductor 11 and the second conductor 12 have the same structure, including multiple core wires, such as 7 core wires in this embodiment. The core wires are aluminum alloy wires, preferably AA8030 type aluminum alloy wires. The single wire specifications and mechanical properties meet the requirements of DLH2-R type in GB / T 30552-2014 "Aluminum Alloy Wires for Cable Conductors", and the electrical properties meet the aluminum conductor resistance specifications in JB / T 8734.2-2016. It has excellent conductivity, tensile strength, bending resistance, low density and other properties, and has the advantages of abundant resources and low price.

[0031] Specifically, the density of the first conductor 11 and the second conductor 12 is 2.71 g·cm³. -3 .

[0032] Specifically, the density of insulator 2 is 0.95 g·cm³. -3 Insulator 2 is made of cross-linked polyethylene insulation material, and its performance and thickness comply with the requirements of GB / T 31840.1-2015. The cross-section of insulator 2 is a dumbbell-shaped structure, which is to prepare for the formation of two air pockets 5 inside cable 1.

[0033] Specifically, the density of protective layer 3 is 1.0 g·cm³. -3 The protective layer 3 is made of natural-colored medium-density polyethylene, which has certain mechanical properties, good flexibility, and low density. The luminescent body 31 is an ultrafine red energy-storing phosphorescent powder added to the protective layer. The luminescent body 31 has a self-luminous function; the energy-storing phosphorescent powder can absorb solar energy during the day and release energy to emit light at night. Even during the day when there is no sunlight, it can still absorb energy from the sun for energy storage.

[0034] Instructions regarding the addition of luminescent powder: The proportion of luminescent powder added to plastics is approximately between 2% and 40%. In injection molding applications, the general addition ratio is 2% to 10%, with a plastic-to-luminescent powder ratio of 1 kg:

[0035] (20-200) grams; within this range, the more phosphorescent powder added, the brighter the light, but too little will result in uneven dispersion. In this solution's floating luminescent cable, the addition of ultrafine red energy-storing phosphorescent powder requires determining the specific amount within this range based on the actual effect.

[0036] Specifically, the density of the water-blocking layer 4 is 1.2 g·cm³. -3 The water-blocking layer 4 is made of transparent polyether-type polyurethane material. It has excellent hydrolysis resistance and can prevent water from penetrating into the interior of cable 1. The total thickness of the water-blocking layer 4 and the protective layer 3 meets the sheath requirements specified in GB / T31840.1-2015.

[0037] Specifically, the spatial dimensions of the two airbags 5 are precisely set so that the overall cable density does not exceed 0.90 g·cm³. -3 Two airbags 5 are installed inside the cable 1. By adjusting the space of the airbags 5, the density of the cable 1 is reduced, allowing the cable 1 to float on the water surface.

[0038] All materials used in this solution are existing technology materials, making them very easy to manufacture.

[0039] Calculations for cable structure dimensions and density in this plan:

[0040] Given a fixed size for the first conductor 11 and the second conductor 12, the thickness of the insulator 2, the thickness of the protective layer 3, and the thickness of the water-blocking layer 4, the overall density requirement of the cable 1 can be achieved by adjusting the size of the airbag 5. The specific cable structure dimensions, weight, and cable density are shown in Table 1 below.

[0041] Table 1 Cable structural dimensions, weight, and density parameters

[0042]

[0043] This solution briefly describes the key processes of cable 1.

[0044] (1) Production of aluminum alloy wire (i.e., first conductor 11 and second conductor 12): The drawing and stranding process of aluminum alloy wire is the same as that of ordinary cable. The single wire aging annealing process is shown in Table 2 below.

[0045]

[0046] (2) Extrusion of insulator 2: An extrusion die is used, and the non-concentric anisotropic die design concept is used to ensure uniform insulation thickness. Ultraviolet light irradiation is used for rapid cross-linking and shaping to prevent deformation of the insulator during cooling.

[0047] (3) Extrusion of protective layer 2: A 39+62 mesh filter is used to solve the problem of clogging and dispersion of luminous powder. A semi-extrusion tube mold is used to form airbag 5 and ensure the tightness of the protective layer and insulation. At the same time as the protective layer 2 is extruded, air is blown into the mold core to pressurize it, ensuring the effectiveness of the airbag 5 space. The air blowing and pressurizing device consists of three parts: connector, blower, and pressure regulating switch.

[0048] (4) Water barrier layer 4 extrusion: The extrusion tube is produced by using a die matching coefficient of 1.05 and a stretching ratio of 2.5. The hot melt is stretched and tightly attached to the protective layer 2. An extruder with a wheel traction device is used to avoid damaging the airbag 5.

[0049] This solution briefly describes the cable production process.

[0050] Aluminum alloy rod → wire drawing → aging annealing → stranding → extrusion of insulator → extrusion of protective layer → extrusion of water-blocking layer → finished product inspection.

[0051] Key operational points for the main processes:

[0052] 1) Wire drawing and aging annealing: The aluminum alloy wire is treated according to the single-wire aging annealing process in Table 2 to ensure its mechanical properties and electrical conductivity.

[0053] 2) Stranding: The treated aluminum alloy wires are stranded into conductors (i.e., the first conductor 11 and the second conductor 12) to ensure the structural stability of the conductors.

[0054] 3) Extruded Insulator 2: Using an extrusion die, the insulator is extruded according to the dumbbell spherical structure requirements, and ultraviolet light irradiation is used for rapid cross-linking and shaping.

[0055] 4) Extruded protective layer 3: Ultra-fine red energy-storing luminescent powder is added to medium-density polyethylene material. The protective layer is extruded through a semi-extrusion die using a 39+62 mesh filter, while air is blown into the die core to pressurize it and ensure the space of the air bladder 5. 5) Extruded water-blocking layer 4: The water-blocking layer is produced by extrusion with a die matching coefficient of 1.05 and a stretch ratio of 2.5 to ensure the integrity and water resistance of the water-blocking layer.

[0056] In summary, the technical solution of this utility model has the following beneficial effects:

[0057] This invention solves the problems of existing fish farming methods that use wired lights suspended from the shore and in the water, which have limitations in the number of light sources, affect aesthetics, hinder net fishing, pose a safety hazard of electric leakage, and fail to emit light, leading to fish aggregation and affecting farming results.

[0061] (4) The light-emitting body can store energy and emit light on its own, providing a light source for attracting insects and raising fish with light, reducing the cost and trouble of setting up additional light sources.

[0062] (5) The cable has two sets of conductors. One set (i.e., the first conductor) is connected to the AC live wire, and the other set (i.e., the second conductor) is connected to the AC neutral wire, which also has the function of transmitting AC power, making it convenient for farmers to use electricity outdoors.
