Description

Technical Field

[0001] The present invention relates to the field of cable technology, and in particular to a novel intelligent cable for street lamps and a manufacturing method thereof. Background Art

[0002] With the acceleration of urbanization and the promotion of the concept of smart cities, the street light system, as an important part of urban infrastructure, has become increasingly intelligent, efficient and energy-saving. Most traditional street light systems use single-function cables for power transmission. This design not only limits the functional scalability of the street light system, but also makes it difficult to meet the needs of modern cities for intelligent management and maintenance of street lights.

[0003] In the prior art, street light cables usually only include power cables, which are used to provide the necessary electrical energy for street lights. However, with the development of Internet of Things technology, big data analysis and remote monitoring technology, street light systems not only need to transmit electrical energy, but also need to realize functions such as data transmission and signal control. For example, high-speed data signals can be transmitted through optical cables to realize real-time monitoring and remote control of street light status, or control instructions can be transmitted through data cables to adjust the brightness, switch status, etc. of street lights, thereby further improving the energy efficiency and intelligence level of street light systems.

[0004] In addition, the layout of traditional street light cables often adopts fixed spacing and connection methods, which lacks flexibility and is difficult to adapt to the changing requirements of street light spacing in different sections. This not only increases the complexity and cost of cable laying, but may also lead to problems such as reduced power transmission efficiency or signal interference in some cases.

[0005] The disclosure of the above background technology content is only used to assist in understanding the inventive concept and technical solution of the present invention. It does not necessarily belong to the prior art of this patent application, nor does it necessarily provide technical guidance. In the absence of clear evidence that the above content has been disclosed before the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Summary of the invention

[0006] In order to solve the technical problems that existing traditional cables cannot simultaneously meet the needs of power, data and optical signal transmission, and cannot flexibly adjust the layout according to the distance between street lamps, the present invention proposes a new type of intelligent cable for street lamps and a manufacturing method thereof, which can simultaneously meet the needs of power, data signal and optical signal transmission, and can flexibly adjust the layout according to the distance between street lamps. The new type of street lamp cable should have good compatibility and scalability, and can support the intelligent upgrade of the street lamp system and future functional expansion, while reducing the laying cost and maintenance difficulty, improving the overall energy efficiency and reliability, and meeting the needs of smart cities for intelligent, efficient and energy-saving street lamp systems.

[0007] In order to achieve the above object, the technical solution of the present invention is as follows:

[0008] On the one hand, the present invention provides a new type of intelligent cable for street lamps, including: a main cable, on which a plurality of branch cables are arranged, the spacing between each two adjacent branch cables is arranged according to the spacing between each two adjacent street lamps, and the branch cables are connected to the main cable through branch connectors, and the main cable and the branch cables both include: a cable core, which is composed of a power cable, an optical cable and a data cable.

[0009] The present invention provides a new type of intelligent cable for street lamps and a manufacturing method thereof, which can simultaneously meet the needs of power, data signal and optical signal transmission, and can flexibly adjust the layout of a new type of street lamp cable according to the distance between street lamps. This cable should have good compatibility and scalability, and can support the intelligent upgrade of the street lamp system and future functional expansion, while reducing the laying cost and maintenance difficulty, improving the overall energy efficiency and reliability, and meeting the needs of smart cities for the intelligent, efficient and energy-saving street lamp systems.

[0011] As a preferred technical solution, the optical cable is arranged at a gap in the power unit and twisted with a group of two adjacent power cables in the power unit.

[0012] As a preferred technical solution, the data cable is arranged at a gap between the power units and is twisted with another group of two adjacent power cables in the power unit.

[0013] As a preferred technical solution, the center of the cable core is filled with a first non-hygroscopic polypropylene film.

[0014] As a preferred technical solution, a wrapping tape and a sheath are sequentially provided on the outside of the power unit, and the gaps between the wrapping tape and the power unit, the optical cable and the data cable are filled with a second non-hygroscopic polypropylene film.

[0015] As a preferred technical solution, the power cable comprises: an annealed soft copper wire conductor, and a cross-linked polyethylene insulation layer is provided on the outer side of the annealed soft copper wire conductor.

[0016] The present invention provides a method for manufacturing a novel intelligent cable for street lamps, and manufacturing the novel intelligent cable for street lamps as described in any one of the above items comprises the following steps:

[0017] S1 uses non-hygroscopic polypropylene filling film to fill the gaps in the cable core to ensure that the insulation tension of each power cable is consistent, and to fill the optical cable and data cable into the cable core in a straight line at a given tension;

[0018] S2 uses a semi-extrusion die to extrude the sheath material directly onto the cable core with the wrapping tape to form a sheath to obtain the branch cable and the main cable;

[0019] S3 uses an injection molding machine to injection-mold the cable branch connector on the main cable according to the distance between every two adjacent street lamps, and connects the branch cable to the main cable through the branch connector.

[0020] As a preferred technical solution, step S3 connects the branch cable to the main cable through a branch connector, and further includes the following steps:

[0021] Use metal clamps inside the branch joint to connect the power cable in the main cable with the power cable in the branch cable, use a special connector for optical cables to connect the optical cable in the main cable with the optical cable in the branch cable, and use a special connector for data cables to connect the data cable in the main cable with the data cable in the branch cable.

[0022] As a preferred technical solution, the power cable manufacturing in step S1 includes the following steps:

[0023] S101 tightly extrude cross-linked polyethylene insulation material outside the annealed soft copper wire conductor to form a cross-linked polyethylene insulation layer.

[0024] The present invention provides a novel intelligent cable for street lamps and a manufacturing method thereof, which has the following beneficial effects:

[0025] 1) A new type of street light cable that can simultaneously meet the needs of power, data signal and optical signal transmission, and can flexibly adjust the layout according to the distance between street lights. This cable should have good compatibility and scalability, support the intelligent upgrade and future function expansion of the street light system, reduce the laying cost and maintenance difficulty, improve the overall energy efficiency and reliability, and meet the needs of smart cities for intelligent, efficient and energy-saving street light systems;

[0026] 2) The main cable is the backbone of the entire cable system. The main cable is responsible for transmitting electricity, optical signals and data signals from the source to each street lamp; the branch cable is laid out according to the distribution spacing of the street lamps to ensure that each street lamp can obtain the required electricity, optical signals and data signals; the branch cable is connected to the main cable through a branch connector, and the branch cable realizes flexible distribution and transmission of signals. This new type of intelligent cable for street lamps integrates power cables, optical cables and data cables to achieve multifunctional integration of power supply, high-speed data transmission and remote monitoring and management. This design not only improves the intelligence level of the street lamp system, but also provides strong support for the construction and development of smart cities.

[0027] 3) The power cable is twisted outside the center of the cable core and distributed in an equilateral triangle to form a power unit. The equilateral triangle structure is a very stable structure with high symmetry and stability. The power cable is twisted in an equilateral triangle distribution, which can evenly distribute the force between the cables and avoid uneven pressure on the cables, thereby increasing the service life of the cables;

[0028] 4) Power cables may generate electromagnetic fields when transmitting electricity, while optical cables are more sensitive to electromagnetic interference; twisting the optical cable with the power cable and placing it in the gap of the power unit can reduce the electromagnetic interference of the power cable on the optical cable to a certain extent, ensuring the stable transmission of the optical signal in the optical cable; in addition, by twisting the optical cable with the power cable, the optical cable can obtain additional mechanical support, thereby improving its mechanical properties such as tensile strength and torsion resistance, and enhancing the stability and durability of the optical cable during use;

[0029] 5) The data cable is cleverly placed in the gap of the power unit, which avoids wasting space inside the cable core and ensures that all components can be arranged compactly and orderly; by twisting the data cable with the power cable, the structure of the entire cable core becomes more stable. This twisting method helps to reduce the movement and deformation of the cable during transportation, installation and use, thereby improving the durability and service life of the cable; by optimizing the layout of the data cable, the attenuation and distortion during data transmission can be reduced, thereby improving the quality and speed of data transmission, which is crucial for functions such as remote monitoring, fault warning and data collection of street lighting systems;

[0030] 6) The center of the cable core is filled with a first non-hygroscopic polypropylene film, which has excellent moisture resistance and can effectively prevent the center of the cable core from getting damp, thereby preventing the inside of the power unit from getting damp and keeping the internal environment dry and stable; by filling the first non-hygroscopic polypropylene film, the power unit can be protected from corrosion by harmful substances such as moisture and oxygen, thereby extending its service life; the first non-hygroscopic polypropylene film is an excellent electrical insulating material, and filling it inside the power unit can further improve the insulation performance of the cable and ensure the safety and stability of power transmission.

[0031] 7) A wrapping tape and a sheath are sequentially arranged on the outside of the power unit, and the gap between the wrapping tape and the power unit is filled with a second non-hygroscopic polypropylene film. Furthermore, the second non-hygroscopic polypropylene film is filled in the gap between the wrapping tape and the power unit, the optical cable and the data cable, and forms a double protection with the first non-hygroscopic polypropylene film, further enhancing the moisture resistance and moisture-proof ability of the cable as a whole; by filling the second non-hygroscopic polypropylene film, the power unit, the optical cable and the data cable can be protected from external mechanical damage, such as extrusion and friction, etc., to ensure the integrity and stability of each component; the filling of the second non-hygroscopic polypropylene film can make full use of the gap space inside the cable, optimize the overall structure of the cable, and make it more compact and stable; the second non-hygroscopic polypropylene film has excellent physical and chemical properties, such as wear resistance and corrosion resistance, etc., and filling it in the cable can further improve the overall performance of the cable, such as weather resistance and aging resistance;

[0032] The wrapping tape is located between the power unit and the sheath, and mainly plays the role of fixing and protecting the cross-linked polyethylene insulation layer. It can prevent the cross-linked polyethylene insulation layer from being perforated by arcs and potential breakdown, and at the same time prevent the core of the cable from being dislocated, squeezed or bent;

[0033] The sheath is the outermost layer of the cable, which mainly protects the cable from damage from the external environment. It can prevent the cable from mechanical damage and chemical corrosion, while improving the wear resistance and weather resistance of the cable.

[0034] 8) The cross-linked polyethylene insulation layer on the outside of the annealed soft copper wire conductor plays multiple roles in the power cable, such as insulation, heat resistance, and improving cable performance and service life. This design not only improves the reliability and safety of the power cable, but also promotes the progress and innovation of the power system;

[0035] Annealed soft copper wire conductors are preferably annealed soft copper wires of GB / T 3953 standard. Annealed soft copper wires of GB / T 3953 standard are made of high-purity electrolytic copper materials and have extremely low resistivity and excellent conductivity. This enables power cables to reduce energy loss and improve transmission efficiency when transmitting current. At the same time, copper wires with high conductivity can also ensure the normal operation and stability of electrical equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention provides a method for manufacturing a novel intelligent cable for street lamps, and manufacturing the novel intelligent cable for street lamps as described in any one of the above items comprises the following steps:

[0053] S1 tightly extrude a cross-linked polyethylene insulation material outside the annealed soft copper wire conductor 41 to form a cross-linked polyethylene insulation layer 42 to obtain a power cable 4;

[0054] S2 uses non-hygroscopic polypropylene filling film to fill the gaps in the cable core to ensure that the insulation tension of each power cable 4 is consistent, and the optical cable 5 and the data cable 6 are filled into the cable core in a straight line under a given tension;

[0055] S2 uses a semi-extrusion die to extrude the sheath material directly onto the cable core with the wrapping tape 8 to form a sheath 9, thereby obtaining the branch cable 2 and the main cable 1;

[0059] The process control of the cabling of the branch cable 2 and / or the main cable 1 is to use non-hygroscopic polypropylene filling film for filling. When the power cable 4 is twisted outside the center of the cable core, the consistency of parameters such as the twisting angle and pitch, and the symmetry of the relative positions of the power cables 4 should be ensured to avoid uneven tension distribution and ensure that the tension of each power cable 4 is consistent.
