[0021] According to the above technical solution, the surface of the metal heat-conducting thin layer is closely attached to the inner wall of the protective rubber layer, and the thickness of the metal heat-conducting thin layer is equal to the distance between the protective rubber layer and the outer insulating layer.
[0022] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:
[0023] 1. It is equipped with a wind-resistant protection mechanism, which uses a protective rubber layer to wrap and protect the surface of the conductor to prevent it from being damaged by foreign objects. The reinforced steel wire improves the overall tensile strength of the conductor to prevent the surface of the conductor from being cracked or broken after long-term use. The right-hand rotating arc plate and the left-hand rotating arc plate on the surface of the rotating ring both play a role in buffering and guiding the external wind. When the wind blows, it will drive the surface of the rotating ring around the fixed metal ring to rotate, and the force generated by the wind will be decomposed through rotation, reducing the impact force of the wind on the conductor itself, improving the stability and wind resistance of the conductor when it is used overhead, and preventing the conductor from shaking significantly after being blown by the wind, causing the conductor connection to be damaged and fall off;
[0024] The right-turning arc plate and the left-turning arc plate face different directions respectively, and can guide wind in multiple directions, thereby improving the application scope of the mechanism; when the rotating ring rotates, the rotating card slides inside the slide groove, thereby improving the stability of the rotating ring; after the rotating ring is bent, the two ends are spliced and fixed by plug-ins and slots, and the installation method is simpler. The fixed metal ring plays a certain role in basic support, reducing the friction of the rotating ring, and the rotation between the rotating ring and the fixed metal ring made of metal material is smoother, so that the rotating ring can rotate smoothly.
[0025] 2. The arc-shaped metal sheet is embedded and installed using the arc groove so that it is located on the surface of the protective rubber layer. The bird-proof spikes drive away birds, making it impossible for birds to stay and stand. The bird-proof spikes correspond to the right-turning arc plate and the left-turning arc plate. The right-turning arc plate and the left-turning arc plate also play a certain blocking role. The rotating ring can rotate, making it impossible for birds to stand stably, thereby reducing the time birds stay on the wire, preventing birds from standing for a long time or in large numbers to exert downward pressure on the wire or bird droppings from corroding the surface of the wire, thereby increasing the service life of the wire.
[0026] 3. An efficient heat dissipation mechanism is provided, which uses arc-shaped heat-conducting metal strips and metal heat-conducting cylinders to conduct and dissipate the heat generated inside the wire, which can quickly discharge the heat inside the wire, and uses the inner metal heat dissipation layer and the outer metal heat dissipation layer to increase the heat dissipation area, so that the heat is evenly distributed inside the wire, preventing a large amount of heat from accumulating and remaining around the core, causing the core to be used in a high-temperature environment for a long time, which is easy to cause damage to the core;
[0027] At the same time, the heat-conducting strips on the surface of the outer metal heat dissipation layer also play a certain role in heat conduction, which can further transfer the heat inside the wire to the outside. The heat penetrates the outer insulating layer through the end of the guide strip, and then can be absorbed by the metal heat-conducting layer for discharge to the outside. The end of the guide strip is embedded in the outer insulating layer. While the outer insulating layer always maintains a certain degree of sealing, the heat can be quickly discharged. The contact area of the guide strip is small, so that the heat will not be excessively precipitated under low temperature conditions outside.
[0028] 4. The inner protective shell and the outer protective shell cooperate with each other to improve the internal structural strength of the conductor, and provide multiple protections for the core. The outer protective shell is used to surround the outer side of the core to provide support and protection to prevent the pressure caused by foreign objects from squeezing the core. The outer folding connector and the inner folding connector have a certain deformation capacity, which makes the conductor ductile and bendable, and has a wider range of uses. At the same time, the buffer layer is located between the inner protective shell and the outer protective shell to buffer and absorb the impact force on the conductor, and provide buffer protection for the inner and outer protective shells.
[0029] To sum up, by combining the wind-resistant protection mechanism and the efficient heat dissipation mechanism, the conductors are protected from the outside and the inside respectively. The force generated by the external wind is transferred, so that the conductors maintain a certain stability when they are overhead, preventing the conductors from swinging and causing damage. The core body is surrounded and protected to a certain extent internally, so that the external impact will not be transmitted to the core body, preventing the inside of the conductor from being squeezed, deformed and damaged. The conductors are protected from multiple aspects, thereby improving the safety of the conductors. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0045] Example: Figure 1-9 As shown, the present invention provides a technical solution, a wind-resistant low-altitude overhead insulated conductor, comprising a core body 1, a shielding layer 2 is sleeved on the surface of the core body 1, an inner insulating layer 3 is extruded and wrapped on the surface of the shielding layer 2, an outer insulating layer 4 is sleeved on the outer side of the inner insulating layer 3, and a wind-resistant protection mechanism 5 is installed on the outer side of the outer insulating layer 4;
[0046] The windproof protection mechanism 5 includes a protective rubber layer 501, a reinforcing steel wire 502, a mounting ring groove 503, a fixing metal ring 504, a sliding groove 505, a rotating ring 506, a slot 507, an insert block 508, a rotating clamping strip 509, a right-turning arc plate 510, a left-turning arc plate 511, an arc groove 512, an arc-shaped metal sheet 513 and a bird-proof spike 514;
[0047] The outer side of the outer insulating layer 4 is sleeved with a protective rubber layer 501, and the inner wall of the protective rubber layer 501 is embedded with reinforcing steel wires 502 at equal intervals along the circumferential direction. The surface of the protective rubber layer 501 is provided with mounting ring grooves 503 at equal intervals, and a fixed metal ring 504 is embedded and installed inside the mounting ring groove 503. The depth of the mounting ring groove 503 is less than the distance from the surface of the protective rubber layer 501 to the reinforcing steel wire 502. The widths of the fixed metal ring 504 and the rotating ring 506 are the same as the width of the mounting ring groove 503. The surface of the fixed metal ring 504 is symmetrically provided with sliding grooves 505, and the surface of the fixed metal ring 504 is sleeved with a rotating ring 506.
[0048] A slot 507 is provided at the top of one end of the rotating ring 506, and an insert block 508 is fixedly connected to the bottom of one end of the rotating ring 506 at a position corresponding to the slot 507. The surfaces of the two ends of the rotating ring 506 fit each other, and the insert block 508 is movably embedded in the slot 507. A rotating clamping strip 509 is symmetrically fixedly connected to the inner wall of the rotating ring 506. The rotating ring 506 is tightly wrapped on the surface of the fixed metal ring 504, and the rotating clamping strip 509 is movably clamped in the inside of the slide groove 505. The surface of the rotating ring 506 is equidistantly fixedly connected with right-hand rotating arc plates 510 along the circumferential direction, and the surface of the rotating ring 506 is equidistantly fixedly installed with left-hand rotating arc plates 511 at a position on one side of the right-hand rotating arc plate 510.
[0049] The number of right-turning arc plates 510 and left-turning arc plates 511 is the same, and the right-turning arc plates 510 and left-turning arc plates 511 are staggered and equidistantly distributed on the surface of the rotating ring 506. The protective rubber layer 501 is used to wrap and protect the surface of the wire so that it will not be damaged by external foreign objects, and the reinforced steel wire 502 improves the overall tensile strength and anti-breaking strength of the wire, preventing the surface of the wire from being cracked or damaged after long-term use. The right-turning arc plates 510 and left-turning arc plates 511 on the surface of the rotating ring 506 both play a role in buffering and guiding external wind. When the wind blows, the rotating ring 506 will be driven to rotate around the surface of the fixed metal ring 504, and the force generated by the wind will be decomposed through rotation, reducing the force of the wind impact on the wire itself, improving the stability of the wire when it is used overhead, and preventing the wire from shaking significantly after being blown by the wind, causing the wire connection to be damaged and falling off;
[0050] The right-turning arc plate 510 and the left-turning arc plate 511 face different directions respectively, and can guide wind forces in multiple directions, thereby improving the application range of the mechanism. When the rotating ring 506 rotates, the rotating clamping strip 509 slides inside the slide groove 505, thereby improving the stability of the rotating ring 506. After the rotating ring 506 is bent, the two ends are spliced and fixed by the plug block 508 and the slot 507, and the installation method is simpler. The fixed metal ring 504 plays a certain role of basic support, reducing the friction of the rotating ring 506. The rotating ring 506 and the fixed metal ring 504 made of metal material rotate and interlace more smoothly, so that the rotating ring 506 can rotate smoothly.
[0051] The top surface of the protective rubber layer 501 is provided with arc grooves 512 at equal intervals, and an arc metal sheet 513 is embedded and installed inside the arc grooves 512. The arc grooves 512 and the mounting ring grooves 503 are staggered and evenly distributed on the surface of the protective rubber layer 501. The top of the arc metal sheet is flush with the surface of the protective rubber layer 501. The surface of the arc metal sheet 513 is evenly installed with bird-proof spikes 514. The arc metal sheet 513 is embedded and installed by using the arc grooves 512 so that it is located on the surface of the protective rubber layer 501. The bird-proof spikes 514 plays a role in driving away birds, making it impossible for birds to stay and stand. The bird-proof spikes 514 correspond to the right-turning arc plate 510 and the left-turning arc plate 511. The right-turning arc plate 510 and the left-turning arc plate 511 also play a certain blocking role. The rotating ring 506 can rotate, making it impossible for birds to stand stably, thereby reducing the time birds stay on the wire, preventing birds from standing for a long time or a large number of them to exert downward pressure on the wire or bird droppings from corroding the surface of the wire, thereby increasing the service life of the wire;
[0052] An efficient heat dissipation mechanism 6 is installed on the surface of the inner insulating layer 3;
[0053] The efficient heat dissipation mechanism 6 includes a heat preservation layer 601, an arc-shaped heat-conducting metal strip 602, an inner metal heat dissipation thin layer 603, a metal heat-conducting cylinder 604, a heat-insulating layer 605, an outer metal heat dissipation thin layer 606, a heat-conducting strip 607, an inner protective shell 608, an inner folding connector 609, a buffer layer 610, an outer protective shell 611, an outer folding connector 612 and a metal heat-conducting thin layer 613;
[0054] The surface of the inner insulating layer 3 is sleeved with a heat preservation layer 601, and the interior of the heat preservation layer 601 is equidistantly embedded with an arc-shaped heat-conducting metal strip 602 along the circumferential direction. The surface of the heat preservation layer 601 is sleeved with an inner metal heat dissipation thin layer 603, and the surface of the arc-shaped heat-conducting metal strip 602 is equidistantly fixedly connected with a metal heat-conducting cylinder 604. The surface of the inner metal heat dissipation thin layer 603 is wrapped and sleeved with a heat insulation layer 605, and the surface of the heat insulation layer 605 is sleeved with an outer metal heat dissipation thin layer 606. The metal heat-conducting cylinder 604 movably penetrates the inner metal heat dissipation thin layer 603 and the heat insulation layer 605, and the end of the metal heat-conducting cylinder 604 is in contact with the inner wall of the outer metal heat dissipation thin layer 606. The surface of the outer metal heat dissipation thin layer 606 is Heat-conducting strips 607 are fixedly installed at equal intervals along the circumferential direction, and grooves are opened at equal intervals on the inner wall of the outer insulating layer 4 along the circumferential direction. The positions of the grooves correspond to the positions of the heat-conducting strips 607. The top of the heat-conducting strips 607 is embedded in the grooves. The arc-shaped heat-conducting metal strips 602 and the metal heat-conducting cylinders 604 are used to conduct and dissipate the heat generated inside the wire, so that the heat inside the wire can be quickly discharged. The inner metal heat dissipation layer 603 and the outer metal heat dissipation layer 606 are used to increase the heat dissipation area, so that the heat is evenly distributed inside the wire, and a large amount of heat is prevented from accumulating and remaining around the core 1, causing the core 1 to be used in a high-temperature environment for a long time, which is easy to cause damage to the core 1.
[0055] At the same time, the heat-conducting strip 607 on the surface of the outer metal heat dissipation thin layer 606 also plays a certain role in heat conduction, and can further transfer the heat inside the wire to the outside. The heat penetrates the outer insulating layer 4 through the end of the guide strip, and can then be adsorbed by the metal heat-conducting thin layer 613 to be discharged outward. The end of the guide strip 607 is embedded in the outer insulating layer 4. When the outer insulating layer 4 always maintains a certain sealing, the heat can also be quickly discharged. In addition, the contact area of the guide strip 607 is small, so that the heat will not be excessively precipitated under low temperature conditions.
[0056] The surface of the outer metal heat dissipation thin layer 606 is equidistantly attached to the inner protective shell 608, and an inner folding connector 609 is fixedly connected between two adjacent inner protective shells 608. The surface of the inner protective shell 608 and the inner folding connector 609 is wrapped and installed with a buffer layer 610. The surface of the buffer layer 610 is equidistantly attached to the outer protective shell 611, and an outer folding connector 612 is fixedly connected between two adjacent outer protective shells 611. The surface of the outer insulating layer 4 is sleeved with a metal heat conductive thin layer 613. The surface of the metal heat conductive thin layer 613 is tightly attached to the inner wall of the protective rubber layer 501. The thickness of the metal heat conductive thin layer 613 is equal to the thickness between the protective rubber layer 501 and the outer insulating layer 4. The spacing between the conductors is equal, and the inner protective shell 608 and the outer protective shell 611 cooperate with each other to improve the structural strength of the inside of the conductor, and provide multiple protections for the core body 1. The core body 1 is surrounded by the outer side thereof to provide support and protection to prevent the pressure caused by foreign matter from squeezing the core body 1. The outer folding connector 609 and the inner folding connector 612 have a certain deformation capacity, so that the conductor has ductility and bendability, and has a wider range of uses. At the same time, the buffer layer 610 is located between the inner protective shell 608 and the outer protective shell 611, which buffers and absorbs the impact force on the conductor, and provides buffer protection for the inner protective shell 608 and the outer protective shell 611.
[0057] The working principle and use process of the present invention are as follows: first, the fixed metal ring 504 is sequentially embedded into the inside of the mounting ring groove 503, and the arc-shaped metal sheet 513 is embedded and fixedly installed in the arc groove 512, then, the rotating ring 506 is taken, bent and fitted on the surface of the fixed metal ring 504, and the rotating clamping strip 509 is moved to be inserted into the inside of the slide groove 505, until the two ends of the rotating ring 506 surround the fixed metal ring 504 for a circle, and the two ends contact each other, so that the plug block 508 is movably inserted into the inside of the slot 507, which plays a role in fixing and connecting the two ends of the rotating ring 506. At this time, the rotating ring 506 is rotated and sleeved on the surface of the fixed metal ring 504. When the wire is installed and used overhead, the staff adjusts the installation direction of the wire so that the arc-shaped metal sheet 513 and the bird-proof spikes 514 face upwards;
[0058] When the wire is in use, the bird-proof spikes 514, the right-turning arc plate 510 and the left-turning arc plate 511 all block the birds from staying. The bird-proof spikes 514 can damage the feet of the birds and prevent them from staying for a long time. The rotating ring 506 can rotate, making the right-turning arc plate 510 and the left-turning arc plate 511 unstable. When the birds stand, they will shake and cannot stand for a long time. This reduces the number and area of birds staying on the wire, protects the wire, and prevents a large number of birds from staying and generating downward pressure to cause wire breakage and damage, and bird droppings and the like to corrode the wire. The reinforced steel wire 502 improves the structural strength of the wire surface, so that the wire will not break easily.
[0059] At the same time, the conductor is in an overhead state, far away from the ground, and is often blown by wind. The wind blows directly to the surface of the conductor, and the right-rotating arc plate 510 or the left-rotating arc plate 511 is affected by the wind, which will directly generate a certain rotation force, driving the rotating ring 506 to rotate on the surface of the fixed metal ring 504, converting the impact force generated by the wind into a rotation force, playing a role in buffering and guiding, alleviating the force directly exerted by the wind on the conductor, enhancing the wind resistance of the conductor, preventing the wind from causing the conductor to shake significantly in the overhead state, and improving the stability of the conductor installation and use. The rotating clamping strip 509 always rotates along the slide groove 505, which acts as a limit guide for the rotating ring 506, making its rotation more stable;
[0060] During the use of the wire, the core 1 continues to generate heat. The heat that continues to remain in the wire is likely to affect the normal use of the core 1. The arc-shaped heat-conducting metal strip 602 absorbs the heat so that the heat can be transferred outward. Through the transfer of the metal heat-conducting cylinder 604, the heat flows to the inner metal heat dissipation layer 603 and the outer metal heat dissipation layer 606. The double heat dissipation increases the heat dissipation area and improves the heat dissipation effect. When the heat continues to increase, the heat will be transferred outward again through the heat-conducting strip 607. By using the end of the heat-conducting strip 607 close to the metal heat-conducting layer 613, the heat is transferred from the inside of the wire to the outside, thereby improving the heat dissipation effect. The heat dissipation efficiency is improved, so that the heat can be smoothly discharged from the wire, and the contact area between the metal heat-conducting cylinder 604 and the heat-conducting strip 607 is small, so that the heat can be transferred outward. In the case of cold outside, a large amount of heat will not be transferred to the outside environment, and the thermal insulation layer 601 and the heat-insulating layer 605 both separate the inside and outside of the wire, so that the core 1 will not be affected by the change of the outside environment temperature. In the case of cold weather, part of the heat is transferred to the metal heat-conducting thin layer 613, which plays a role in heat preservation on the surface of the wire, and heats and melts the snowflakes falling on the surface of the wire, preventing excessive accumulation of snowflakes from causing excessive pressure on the wire;
[0061] The inner protective shell 608 and the outer protective shell 611 both support and protect the inside of the wire, thereby improving the structural strength of the wire, so that when the wire is impacted by the outside world, it is isolated and protected to a certain extent, preventing the core 1 from being deformed and damaged by the impact, and a buffer layer 610 is filled between the inner protective shell 608 and the outer protective shell 611 to buffer the impact, and the inner folding connector 609 and the outer folding connector 612 themselves have a certain deformation ability, so that the wire has the hard support and protection of the inner protective shell 608 and the outer protective shell 611, and also has a certain bending and deformation ability, which is more convenient to install and use.
