Abstract
Description
Technical Field
[0001] This invention relates to the field of power cable technology, specifically to an intelligent high-end power transmission cable. Background Technology
[0002] Power cables are cables used to transmit and distribute high-power electrical energy. They consist of a conductor, insulation layer, shielding layer, and protective layer. They are mainly laid in urban underground power grids, power plant lead-out lines, and other scenarios. The proportion of cables in power lines is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of the power system. They include power cables of various voltage levels from 1 to 5,000 kilowatts and above, and various types of insulation. According to voltage level, they can be divided into medium and low voltage power cables (35 kV and below), high voltage cables (110 kV and above), ultra-high voltage cables (275 to 800 kV), and extra-high voltage cables (1,000 kV and above). Wires and cables play a very important linking role in my country's infrastructure construction.
[0003] For example, an existing Chinese patent, application number 202411427285.7, entitled "A Cable with an Intelligent Alarm Device," describes a cable with an alternating first and second arc-shaped plates. The second and first arc-shaped plates move outward until the first arc-shaped plate stops moving outward due to external factors. At this point, the gas in the third air chamber no longer flows outward. When external pressure is applied to the cable, it squeezes the first arc-shaped plate, causing it to move inward. Under the action of a torsion spring, the first swing plate does not swing inward, preventing external pressure from being directly transmitted to the inside of the cable. This avoids damage to the cable's interior from external pressure, increases the cable's service life, and ensures that the cable's internal cores maintain a good shape and connection, preventing abnormal resistance changes caused by core deformation or breakage.
[0004] However, the lack of precise detection structures after cable laying and installation makes it impossible to promptly detect internal cable faults, leading to damage to the entire line and equipment and causing significant economic losses. Therefore, this invention provides an intelligent high-end power transmission cable to meet people's needs. Summary of the Invention
[0005] This invention provides an intelligent high-end power transmission cable that can effectively solve the problem mentioned in the background art: the lack of a precise detection structure after cable laying and installation leads to the inability to promptly grasp information when internal faults occur in the cable, resulting in damage to the entire line and equipment and causing great economic losses.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent high-end power transmission cable, comprising a core, the surface of which is extruded and wrapped with a rubber insulation layer, the surface of which is sleeved with a braided copper mesh shielding layer, the surface of which is sleeved with a filler layer, the surface of which is extruded and wrapped with a rubber protective layer, and a multi-functional monitoring and protection mechanism is provided on the top of the rubber protective layer.
[0007] The multifunctional monitoring and protection mechanism includes a positioning rigid rubber block;
[0008] The top surface of the rubber protective layer is equidistantly equipped with positioning rigid rubber blocks, and the bottom of each positioning rigid rubber block is embedded with an elastic buffer rubber pad. An arc-shaped rubber strip is installed above the top of the rubber protective layer, and the bottom of the arc-shaped rubber strip is equidistantly connected with arc-shaped positioning splicing blocks.
[0009] The surface of the rubber protective layer is provided with equidistant positioning ring grooves. An annular elastic positioning rubber strip is embedded in the inside of the positioning ring groove. A pressure sensor is installed on the top of the annular elastic positioning rubber strip. An arc-shaped buffer silicone pad is installed on the top of the pressure sensor.
[0010] Both sides of the arc-shaped rubber strip are connected to sealing rubber strips, and deformation-reinforcing metal sheets are equidistantly embedded inside the sealing rubber strips.
[0011] According to the above technical solution, the arc-shaped rubber strip and the positioning rigid rubber block are located on the same vertical plane, the arc-shaped positioning splicing block is movably embedded inside the positioning rigid rubber block, and the bottom end of the arc-shaped positioning splicing block is in contact with the top end of the elastic buffer rubber pad block.
[0012] According to the above technical solution, the top end of the arc-shaped buffer silicone pad is attached to the bottom end of the arc-shaped rubber strip, the pressure sensor is connected to the cable operation data acquisition chip, and the bottom end of the sealing rubber strip is attached to the surface wall of the rubber protective layer.
[0013] According to the above technical solution, a metal monitoring wire is embedded in one end of the filling layer, and an installation groove is provided at an equal distance from the corresponding position of the metal monitoring wire at one end of the rubber protective layer. An arc-shaped sensing metal sheet is embedded in the installation groove, and a temperature sensor is installed in the middle of the installation groove.
[0014] The mounting groove has symmetrically provided positioning slots at both ends. A support and protective frame is installed on the surface of the temperature sensor. Elastic swing metal pieces are symmetrically connected to both sides of the support and protective frame. Positioning blocks are connected to the ends of the elastic swing metal pieces. A sealing and protective cover plate is installed on the surface of the support and protective frame.
[0015] According to the above technical solution, a short metal post is connected to the middle of the arc-shaped sensing metal sheet. The short metal post is inserted into the interior of the filling layer and connected to the metal monitoring wire. The temperature sensor is connected to an external controller.
[0016] According to the above technical solution, the positioning card block is snapped into the inside of the positioning card slot, the supporting protective frame is in close contact with the surface and bottom of the temperature sensor, and the supporting protective frame and the sealing protective cover cover the temperature sensor.
[0017] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.
[0018] 1. Equipped with a multi-functional monitoring and protection mechanism, which uses arc-shaped positioning splicing blocks and positioning hard rubber blocks in combination to position and install the arc-shaped rubber strip, allowing it to be spliced and covered on the outside of the rubber protective layer, providing protection above the cable and preventing the buried cable from being dug up during ground excavation. In addition, the pressure sensor monitors the impact force and provides timely feedback and reminders when the cable is dug up, making the excavation process more accurate and safe.
[0019] Meanwhile, the elastic buffer rubber pads act as a buffer, cushioning the impact force of the excavation and preventing direct impact on the inside of the cable. The arc-shaped buffer silicone pads protect the end of the pressure sensor, isolating it during impact and preventing the impact force from directly damaging the end of the pressure sensor.
[0020] 2. The positioning ring groove and the annular elastic positioning strip work together to position and install the pressure sensor, which can be fixed on the surface of the cable and has a strong connection and will not easily fall off.
[0021] The sealing rubber strip seals both sides of the curved rubber strip, providing a sealed and protective barrier for the pressure sensor. Furthermore, the deformation-enhancing metal sheet's own deformation and shaping capabilities make the sealing rubber strip and the rubber protective layer more convenient and quick to seal.
[0022] 3. The combination of metal monitoring wire and arc-shaped induction metal sheet facilitates the monitoring of temperature changes inside the cable. At the same time, the temperature sensor plays a monitoring and protection role, monitoring abnormal temperature rises that occur when there is a fault in the internal circuit of the cable. This can provide early warning of cable faults, allowing for repair and replacement before the line is damaged, preventing cable short circuits and fires that could damage equipment. Furthermore, the accurate location of faults greatly facilitates the staff in finding the faulty circuit.
[0023] At the same time, the positioning blocks and positioning slots work together to lock and fix the support protective frame and the sealing protective cover plate, thereby covering and protecting the temperature sensor and preventing the temperature sensor from being directly exposed to the outside and easily damaged by impact.
[0024] 4. A support and buffer mechanism is provided, which uses the arc-shaped fitting strip and the support side strip to support and stabilize the cable, making the cable placement and installation more stable. The wear-resistant protective metal sheet improves the overall wear resistance and prevents the cable from being worn during installation and dragging, which would affect its overall structure.
[0025] Simultaneously, the buffer airbags and telescopic expansion zones work together to provide buffer support for the bottom of the cable, reducing the vibration or loosening of the buried cable due to external environmental influences. They also buffer the vibration and impact of vehicles or construction on the ground, improving the stability of cable laying. Furthermore, the wedge-shaped rubber splicing strips and wedge-shaped splicing grooves work together to simplify the splicing and installation method between the arc-shaped fitting strips and the rubber protective layer.
[0026] 5. The L-shaped fixed extension block and the self-adjusting metal spring are used in conjunction to facilitate the adjustment of the position of the swing support block, so that the bottom end of the swing support block is close to the installation plane, which plays an auxiliary support role for the cable as a whole, improves the overall stability of the cable after the buffer airbag is inflated, and prevents the cable from tilting to one side, which would cause the buffer airbag to fail to be close to the ground for cushioning.
[0027] In summary, by combining a multi-functional monitoring and protection mechanism with a support and buffer mechanism, the support side strips provide overall support and stability to the cable during installation and laying. This also positions the curved rubber strip and pressure sensor, preventing cable misalignment from affecting normal pressure safety monitoring. Simultaneously, the curved rubber strip and elastic buffer rubber pads provide some cushioning protection when impacted from above, while the buffer airbag located below deforms under impact, further providing cushioning protection and improving the overall safety of the cable.

[0044] The multi-functional monitoring and protection mechanism 6 includes a positioning rigid rubber block 601, an elastic buffer rubber pad 602, an arc-shaped rubber strip 603, an arc-shaped positioning splicing block 604, a positioning ring groove 605, an annular elastic positioning rubber strip 606, a pressure sensor 607, an arc-shaped buffer silicone pad 608, a sealing and bonding rubber strip 609, a deformation-reinforced metal sheet 610, a metal monitoring wire 611, an installation groove 612, an arc-shaped sensing metal sheet 613, a temperature sensor 614, a positioning slot 615, a support and protection frame 616, an elastic swinging metal sheet 617, a positioning block 618, and a sealing and protection cover plate 619.
[0045] The top surface of the rubber protective layer 5 is equidistantly fitted with positioning rigid rubber blocks 601. The bottom of each positioning rigid rubber block 601 is embedded with an elastic buffer rubber pad 602. An arc-shaped rubber strip 603 is installed above the top of the rubber protective layer 5. The bottom of the arc-shaped rubber strip 603 is equidistantly connected with an arc-shaped positioning splicing block 604.

The arc-shaped positioning splicing block 604 is movably embedded inside the positioning rigid rubber block 601.

[0046] The surface of the rubber protective layer 5 is provided with equidistant positioning grooves 605. An annular elastic positioning strip 606 is embedded in the positioning groove 605.

The top of the arc-shaped buffer silicone pad 608 is in contact with the bottom of the arc-shaped rubber strip 603. The pressure sensor 607 is connected to the cable operation data acquisition chip. The bottom of the sealing rubber strip 609 is in contact with the surface wall of the rubber protective layer 5. One cable operation data acquisition chip is provided every 3-5 meters. The data cable connects the cable operation data acquisition chips in series.
[0047] Both sides of the arc-shaped rubber strip 603 are connected to sealing rubber strips 609. Deformation-reinforcing metal sheets 610 are equidistantly embedded inside the sealing rubber strips 609. The arc-shaped positioning splicing block 604 and the positioning rigid rubber block 601 cooperate with each other to position and install the arc-shaped rubber strip 603, so that it can be spliced and covered on the outside of the rubber protective layer 5, providing protection above the cable and preventing the buried cable from being dug up during ground excavation. The pressure sensor 607 monitors the impact force and provides timely feedback and reminders when the cable is dug up, making the excavation process more accurate and safe.
[0048] Meanwhile, the elastic buffer rubber pad 602 plays a buffering role, buffering the force of the digging impact and preventing direct impact on the inside of the cable, while the arc-shaped buffer silicone pad 608 protects the end of the pressure sensor 607 and plays an isolation role during impact, preventing the impact force from directly acting on the end of the pressure sensor 607 and causing damage.
[0049] The positioning groove 605 and the annular elastic positioning strip 606 work together to position and install the pressure sensor 607, so that it can be fixed on the surface of the cable and the connection is strong and will not easily fall off.
[0050] The sealing rubber strip 609 seals both sides of the arc-shaped rubber strip 603, providing a sealed and isolated protection for the pressure sensor 607. Furthermore, the deformation-strengthening metal sheet 610's own deformation and shaping capabilities make the sealing rubber strip 609 and the rubber protective layer 5 more convenient and quick to seal and bond.
[0051] A metal monitoring wire 611 is embedded in one end of the filling layer 4. An installation groove 612 is provided at an equal distance from the metal monitoring wire 611 at one end of the rubber protective layer 5. An arc-shaped sensing metal sheet 613 is embedded in the installation groove 612. A temperature sensor 614 is installed in the middle of the installation groove 612. A metal short post is connected to the middle of the arc-shaped sensing metal sheet 613. The metal short post is inserted into the filling layer 4 and connected to the metal monitoring wire 611.

Positioning blocks 618 are connected to the ends of the elastic swing metal pieces 617. A sealing protective cover plate 619 is installed on the surface of the support and protective frame 616. The positioning blocks 618 are snapped into the inside of the positioning slots 615. The support and protective frame 616 is in close contact with the surface and bottom of the temperature sensor 614. The support and protective frame 616 and the sealing protective cover plate 619 cover the temperature sensor 614. The metal monitoring wire 611 and the arc-shaped sensing metal piece 613 work together to facilitate the monitoring of temperature changes inside the cable. At the same time, the temperature sensor 614 plays a monitoring and protection role, monitoring abnormal temperature rises when there is a fault in the internal circuit of the cable. It can provide early warning of cable faults, and repair and replace the cable before the line is damaged, preventing the cable from short-circuiting and catching fire, which can cause equipment damage. Moreover, the positioning is accurate, which greatly facilitates the staff to find the faulty circuit.
[0053] At the same time, the positioning block 618 and the positioning slot 615 cooperate with each other to fix the support protection frame 616 and the sealing protection cover 619, thereby covering and protecting the temperature sensor 614 and preventing the temperature sensor 614 from being directly exposed to the outside and easily damaged by impact.
[0054] A support and buffer mechanism 7 is provided at the bottom of the rubber protective layer 5;
[0055] The support and buffer mechanism 7 includes an arc-shaped fitting strip 701, a support side strip 702, a wear-resistant protective metal sheet 703, a buffer airbag 704, a telescopic expansion area 705, a connecting air pipe 706, a sealing plug 707, a wedge-shaped rubber splicing strip 708, a wedge-shaped splicing groove 709, an L-shaped fixed extension block 710, a mounting slot 711, a self-adjusting metal spring 712, a swing support block 713, and an arc-shaped locking block 714;
[0056] An arc-shaped adhesive strip 701 is attached to the bottom surface of the rubber protective layer 5. Supporting side strips 702 are symmetrically connected to the bottom ends of the arc-shaped adhesive strip 701. A wear-resistant protective metal sheet 703 is installed at the bottom end of the supporting side strip 702.
[0057] A buffer airbag 704 is installed at the middle of the bottom end of the arc-shaped fitting strip 701. The bottom of the buffer airbag 704 is provided with a telescopic expansion area 705. A connecting air tube 706 is connected to the middle of one end of the buffer airbag 704. A sealing plug 707 is installed at the end of the connecting air tube 706. The edge of the buffer airbag 704 fits against the inner wall of the supporting side strip 702. The connecting air tube 706 moves through one of the supporting side strips 702. The sealing plug 707 is located on one side of the surface of the supporting side strip 702.
[0058] The top of the arc-shaped fitting strip 701 is symmetrically connected with wedge-shaped rubber splicing strips 708, and the bottom surface of the rubber protective layer 5 is symmetrically provided with wedge-shaped splicing grooves 709. The arc-shaped fitting strip 701 and the supporting side strip 702 work together to support and stabilize the cable, making the cable placement and installation more stable. The wear-resistant protective metal sheet 703 improves the overall wear resistance and prevents the cable from being worn during installation and dragging, which would affect its overall structure.
[0059] At the same time, the buffer airbag 704 and the telescopic expansion area 705 work together to provide buffer support for the bottom of the cable, reducing the vibration or loosening of the buried cable due to the influence of the external environment, and buffering the vibration and impact of the ground caused by vehicle driving or construction, thus improving the stability of cable laying. In addition, the wedge-shaped rubber splicing strip 708 and the wedge-shaped splicing groove 709 work together to make the splicing and installation between the arc-shaped fitting strip 701 and the rubber protective layer 5 simple.
[0060] Two support side strips 702 are each equidistantly connected to one end of an L-shaped fixed extension block 710. The bottom end of the L-shaped fixed extension block 710 has an inner mounting groove 711. A self-adjusting metal spring 712 is connected to the middle of the bottom end of the L-shaped fixed extension block 710. A swing support block 713 is connected to the bottom of the self-adjusting metal spring 712. One end of the swing support block 713 is connected to an arc-shaped locking block 714. The arc-shaped locking block 714 is movably locked inside the mounting groove 711. The swing support blocks 713 are symmetrically distributed on both sides of the buffer airbag 704. The L-shaped fixed extension block 710 and the self-adjusting metal spring 712 cooperate with each other to facilitate the adjustment of the position of the swing support block 713, so that the bottom end of the swing support block 713 is close to the mounting plane, which plays an auxiliary support role for the cable as a whole. This improves the overall stability of the cable after the buffer airbag 704 is inflated and prevents the cable from tilting to one side, which would cause the buffer airbag 704 to fail to keep close to the ground for cushioning.
[0061] The working principle and usage process of this invention are as follows: First, during cable production and installation, the annular elastic positioning rubber strip 606 needs to be embedded into the positioning ring groove 605 so that the pressure sensor 607 is installed on the surface of the rubber protective layer 5. The pressure sensor 607 and the positioning rigid rubber block 601 are located on the same vertical plane, ensuring that the pressure sensor 607 is located at the top of the cable. Then, take the arc-shaped rubber strip 603 and cover it above the rubber protective layer 5 so that the arc-shaped positioning splicing block 604 is embedded into the positioning rigid rubber block 601 and contacts the elastic buffer rubber pad 602. Then, press down on the two sealing and bonding rubber strips 609, and the deformation reinforcing metal sheet 610 is pressed and deformed so that the bottom ends of the two sealing and bonding rubber strips 609 are tightly attached to the surface wall of the rubber protective layer 5.
[0062] Before cable laying, the arc-shaped fitting strip 701 is tightly attached to the bottom surface of the rubber protective layer 5, and the wedge-shaped rubber splicing strip 708 is embedded into the wedge-shaped splicing groove 709, so that the arc-shaped fitting strip 701 and the rubber protective layer 5 are spliced and fixed together. The bottom of the cable is supported by two support side strips 702, so that the cable is placed stably. At the same time, when the cable is pulled and laid, the wear-resistant protective metal sheet 703 rubs against the ground, reducing the probability of cable wear. The self-adjusting metal spring 712 pushes the swing support block 713. The arc-shaped locking block 714 at one end of the swing support block 713 is movably embedded into the installation slot 711, so that the swing support block 713 is pushed and the bottom end is close to the ground.
[0063] After the cable is placed in the predetermined burial location, the sealing plug 707 is removed, and the buffer airbag 704 is inflated using an external air pump and connecting air pipe 706. This allows the telescopic expansion area 705 at the bottom of the buffer airbag 704 to expand downwards, lifting the entire cable. This keeps the support side strip 702 and the wear-resistant protective metal plate 703 away from the installation ground. Under the elastic push of the self-adjusting metal spring 712, the bottom of the swing support block 713 is always in contact with the ground, providing support for the cable and preventing the cable from tilting when the telescopic expansion area 705 expands.
[0064] Next, take the support and protective frame 616 and the sealing and protective cover 619, press the elastic swing metal piece 617 inward, align the positioning block 618 with the positioning slot 615, release the elastic swing metal piece 617 so that the positioning block 618 is engaged inside the positioning slot 615, and the support and protective frame 616 and the sealing and protective cover 619 are fixed on the surface of the temperature sensor 614, which plays a supporting, stable and protective role for the temperature sensor 614.
[0065] During cable use, if a line fault occurs, it can cause abnormal internal temperature rise in the cable. The metal monitoring wire 611 absorbs and conducts the internal temperature of the cable, and the arc-shaped sensing metal sheet 613 transfers the heat to the temperature sensor 614. The temperature sensor 614 continuously monitors the internal temperature changes of the cable and promptly sends out an alert signal when it detects abnormal temperature rise, providing staff with accurate fault location and playing an early warning role. Based on the signal location provided, staff can carry out inspection and maintenance before the line is completely damaged, reducing the losses caused by line damage and demonstrating a certain degree of intelligent safety monitoring.
[0066] Meanwhile, with the cable buried deep underground, if excavation is carried out in the area, the excavation equipment cannot precisely control the position around the cable while digging through the soil. If the equipment touches the cable, it will first come into contact with the arc-shaped rubber strip 603. The arc-shaped rubber strip 603 will be squeezed downwards by the impact. The elastic buffer rubber pad 602 will be compressed and rebounded after being pressed to buffer the impact. The arc-shaped buffer silicone pad 608 will also buffer the impact and transmit it to the pressure sensor 607. The pressure sensor 607 will provide feedback on the impact force to remind that the cable has been dug up, preventing the cable from breaking due to continued excavation. When the cable is compressed, the buffer airbag 704 and the telescopic expansion area 705 at its bottom are in an expanded state and have a certain elasticity. After being compressed, they sink and deform, which plays a certain role in the auxiliary buffer protection against the impact, so that the cable can always operate normally under safe conditions.
[0067] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
