Description

Technical Field

[0001] This utility model relates to the field of photovoltaic control cable technology, and in particular to a heat-resistant multi-strand photovoltaic control cable. Background Technology

[0002] In recent years, with the rapid development of my country's photovoltaic industry, the market demand for photovoltaic cables has increased significantly, which has provided more market opportunities for photovoltaic cable manufacturers, but at the same time, it has also placed higher demands on the product quality of the photovoltaic cables produced.

[0003] In the prior art, such as Chinese patent CN203338799U, a solar photovoltaic cable is composed of copper wire conductors, an insulation layer, and an outer sheath. The copper wire conductors are twisted together to form a conductor core, the insulation layer is extruded over the core, and the outer sheath is extruded over the insulation layer. This utility model has a simple structure, high environmental performance, strong fire resistance, and also has the characteristics of high temperature resistance and acid and alkali resistance.

[0004] In the aforementioned patent, by wrapping the conductor with a winding remote and a sheath layer, it has good insulation and fireproof effects. However, when photovoltaic control cables are used for a long time, under direct sunlight and during operation, the surface and interior of the photovoltaic control cables will generate high temperatures, which can easily affect the stability of the photovoltaic control cables. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, when photovoltaic control cables are used for a long time, the surface and interior of the photovoltaic control cables will generate high temperatures, which can easily affect the stability of the photovoltaic control cables under direct sunlight and during operation. Therefore, a heat-resistant multi-strand photovoltaic control cable is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat-resistant multi-strand photovoltaic control cable, comprising: a cable body, wherein multiple cable bodies are provided, and multiple conductor bundles are equidistantly arranged on the inner surfaces of the multiple cable bodies, the multiple conductor bundles are arranged in multiple groups, the multiple groups of conductor bundles are intertwined, a protective layer is provided on the outer surface of each of the multiple cable bodies, a shielding layer is provided on the outer surface of the protective layer, and an outer sheath is provided on the outer surface of the shielding layer; and a protection component, wherein the protection component is disposed on the outer surface of the outer sheath, and the protection component includes an inner sleeve.

[0007] Preferably, the inner ring is disposed on the outer surface of the outer sheath, and the inner surface of the inner ring is in close contact with the outer sheath.

[0008] Preferably, a plurality of support blocks are equidistantly arranged on the outer surface of the inner ring, and a plurality of through holes are equidistantly opened on the outer surface of the plurality of support blocks.

[0009] Preferably, an outer ring is provided on the outer surface of each of the multiple support blocks, and multiple heat sinks are provided at equal intervals on the outer surface of the outer ring, the heat sinks being ring-shaped.

[0010] Preferably, a conductor is provided at the center of the protective layer, and multiple cable bodies are intertwined on the outer surface of the conductor.

[0011] Preferably, a filler layer is provided between the outer surfaces of the plurality of cable bodies and conductors, the filler layer being located on the inner surface of the protective layer.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during use, an inner ring is set on the outer layer of the multi-strand photovoltaic control cable, so that the temperature generated during internal operation is transferred to the outer ring through the inner ring. The outer ring and its surface are provided with multiple annular pile heat sinks, which increases the contact area with air, thus alleviating the heat inside the multi-strand photovoltaic control cable. At the same time, the inner ring and the outer ring are separated into multiple cavities by multiple support blocks. The multiple cavities are connected by multiple through holes to form a heat insulation layer, which prevents the internal temperature of the multi-strand photovoltaic control cable from being aggravated when sunlight directly shines on the control cable. This gives the multi-strand photovoltaic control cable a better heat resistance effect and improves the stability of the heat-resistant multi-strand photovoltaic control cable.

[0014] 2. In this utility model, when in use, by setting a conductor at the center of the protective layer, the multi-strand cable body is wrapped around the outer surface of the conductor, so that when the multi-strand photovoltaic control cable is pulled, the conductor will bear a large tensile force, thus improving the tensile strength of the heat-resistant multi-strand photovoltaic control cable.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model provides a heat-resistant multi-strand photovoltaic control cable, comprising: a cable body 4, wherein multiple cable bodies 4 are provided, and multiple conductor bundles 7 are equidistantly arranged on the inner surface of the multiple cable bodies 4, the multiple conductor bundles 7 are arranged in multiple groups, and the multiple groups of conductor bundles 7 are intertwined; a protective layer 3 is provided on the outer surface of the multiple cable bodies 4, a shielding layer 2 is provided on the outer surface of the protective layer 3, and an outer sheath 1 is provided on the outer surface of the shielding layer 2; and a protection component 8, which is disposed on the outer surface of the outer sheath 1. The protection component 8 includes an inner sleeve 801, which is disposed on the outer surface of the outer sheath 1 and is tightly fitted to the outer sheath 1; multiple support blocks 802 are equidistantly arranged on the outer surface of the inner sleeve 801; multiple through holes 803 are equidistantly opened on the outer surface of the multiple support blocks 802; an outer sleeve 804 is provided on the outer surface of the multiple support blocks 802; and multiple heat sinks 805 are equidistantly arranged on the outer surface of the outer sleeve 804, the heat sinks 805 being ring-shaped.

[0024] The overall effect of Embodiment 1 is that, when using the heat-resistant multi-strand photovoltaic control cable, the control cable consists of multiple cable bodies 4 intertwined on the outer surface of the conductor 5. The interiors of the multiple control cables are composed of multiple fixed conductor bundles 7 intertwined. A filling layer 6 is provided between the conductor 5 and the multi-strand cable body 4, which can fix the multi-strand cable within the protective layer 3. The protective layer 3 prevents rainwater penetration, avoiding rainwater infiltration into the multi-strand cable and affecting its use. The shielding layer 2 on the outer surface of the protective layer 3 can shield electromagnetic signals, preventing external electromagnetic signals from interfering with the control cable signal. The outer sheath 1 is made of insulating material to prevent cable leakage and protect surrounding personnel and equipment. To prevent damage, the outer surface of the outer sheath 1 is tightly fitted to the inner surface of the inner sleeve 801. The heat generated inside the multi-strand photovoltaic control cable is transferred through the inner sleeve 801 to multiple support blocks 802, and dissipated through the outer sleeve 804 and multiple heat sinks 805 equidistantly arranged on its surface. At the same time, multiple cavities are formed between the outer sleeve 804 and the inner sleeve 801. These cavities are connected by multiple through holes 803 to form a heat insulation layer. This prevents the internal temperature of the multi-strand photovoltaic control cable from being aggravated by direct sunlight, thus giving the multi-strand photovoltaic control cable a better heat resistance effect and improving the stability of the heat-resistant multi-strand photovoltaic control cable.

[0025] Example 2

[0026] like Figures 1-4 As shown, a conductor 5 is provided at the center of the protective layer 3, and multiple cable bodies 4 are wrapped around the outer surface of the conductor 5. A filling layer 6 is provided between the multiple cable bodies 4 and the outer surface of the conductor 5, and the filling layer 6 is located on the inner surface of the protective layer 3.

[0027] The effect achieved by the entire embodiment 2 is that, during use, by setting the conductor 5 at the center of the protective layer 3, the multi-strand cable body 4 is wrapped around the outer surface of the conductor 5, so that when the multi-strand photovoltaic control cable is pulled, the conductor 5 will bear a large tensile force, thereby improving the tensile strength of the heat-resistant multi-strand photovoltaic control cable.

[0028] Working Principle: In the use of heat-resistant multi-strand photovoltaic control cables, the control cable consists of multiple cable bodies 4 intertwined on the outer surface of conductors 5. The interiors of the multiple control cables are formed by multiple fixed conductor bundles 7 intertwined. A filling layer 6 is provided between the conductors 5 and the multi-strand cable bodies 4, which secures the multi-strand cables within the protective layer 3. The protective layer 3 prevents rainwater penetration, avoiding water infiltration into the multi-strand cable and affecting its use. The shielding layer 2 on the outer surface of the protective layer 3 shields electromagnetic signals, preventing external electromagnetic interference with the control cable signal. The outer sheath 1 is made of insulating material to prevent cable leakage and harm to surrounding personnel and equipment. Because the outer surface of the outer sheath 1 is tightly fitted to the inner surface of the inner ring 801, the heat generated inside the multi-strand photovoltaic control cable will be... The heat is transferred to multiple support blocks 802 through the inner ring 801, and dissipated through the outer ring 804 and multiple heat sinks 805 equidistantly arranged on its surface. At the same time, multiple cavities are formed between the outer ring 804 and the inner ring 801. These cavities are connected by multiple through holes 803 to form a heat insulation layer. This prevents the internal temperature of the multi-strand photovoltaic control cable from being aggravated by direct sunlight, thus improving the heat resistance of the multi-strand photovoltaic control cable and enhancing its stability. By setting a conductor 5 at the center of the protective layer 3, the multi-strand cable body 4 is wrapped around the outer surface of the conductor 5. When the multi-strand photovoltaic control cable is pulled, the conductor 5 can bear a large tensile force, improving the tensile strength of the heat-resistant multi-strand photovoltaic control cable.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
