Description

Technical Field

[0001] This invention relates to the field of cable technology, and in particular to an overhead cable with an intelligent control system. Background Technology

[0002] Overhead cables are a crucial component of the power system, responsible for long-distance, high-capacity power transmission. Erected on poles and towers, they form the backbone of the power transmission and distribution network. Serving as the "highways" of power transmission, they undertake high-voltage and ultra-high-voltage transmission tasks from power plants to load centers. Their lines can traverse complex terrain, enabling wide-area power distribution and flexible access, making them the most economical way to cover vast urban and rural areas. Compared to underground cables, for long distances and high voltage levels, their construction costs are lower, the construction period is shorter, and they are easier to inspect and maintain.

[0003] Currently, overhead cables, due to their long-term high-altitude location, accumulate dust and snow from years of wind, sand, rain, and snow, as well as attracting birds. If these deposits are not quickly removed, they can easily cause corrosion and damage to the cable surface, increase their weight, and put pressure on the towers. Furthermore, current overhead cables primarily rely on external airflow for heat dissipation, failing to quickly conduct internal heat away, resulting in very limited and inconsistent heat dissipation performance. Summary of the Invention

[0004] The technical problem this invention aims to solve is that current overhead cables cannot quickly remove surface ice, snow, and birds, which easily causes corrosion and damage to the cable surface, increases their weight, and increases the pressure on the towers; at the same time, they cannot quickly conduct internal heat away from the outside, resulting in very fixed and limited heat dissipation performance.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an overhead cable with an intelligent control system, including a cable body, wherein the cable body consists of a conductor, conductor insulation, conductor shield, filler, inner sheath, insulation shield and outer sheath from the inside out, a compression flexible guide tube is provided between the inner sheath and the outer sheath, and an intelligent detection cover is fitted at both ends of the cable body, and an external drive module is installed on the side wall of the intelligent detection cover.

[0006] The outer surface of the compression-type flexible guide tube has a lateral metal extension heat dissipation plate that is connected to the inner wall of the outer sheath.

[0007] The outer side of the outer sheath has an annular mounting groove for fixing the intelligent detection cover at the connection end. The annular mounting groove has a plurality of side-mounted guide nozzles that are connected to the compression flexible guide tube.

[0008] The intelligent detection cover includes an arc-shaped first sealed cover and an arc-shaped second sealed cover fitted inside an annular mounting groove.

[0009] The arc-shaped first sealed cover and the arc-shaped second sealed cover have interconnected internal flow channels, and the inner arc-shaped surfaces of the arc-shaped first sealed cover and the arc-shaped second sealed cover have internal connecting holes that are connected to the internal flow channels.

[0010] The bottom of the arc-shaped second sealed cover has a downwardly protruding bottom guide frame. A side-mounted support rod for controlling the external drive module is installed on the side wall of the bottom guide frame. The external drive module is movably assembled with the bottom guide frame through an integrated guide seat.

[0011] The external drive module includes an external cover with a flow guide seat on top, centrifugal flow guide vanes installed inside the external cover, and a detachable liquid storage tank fixed to the side wall of the external cover.

[0012] The detachable liquid storage tank is internally elastically fitted with a built-in reset piston and a compression spring.

[0013] The outer surface of the external cover is provided with an internally threaded assembly through hole for installing a detachable liquid storage tank, and a metal filter screen is installed inside the internally threaded assembly through hole.

[0014] A temperature and humidity sensor controller is installed on the outer surface of the arc-shaped first sealed enclosure.

[0015] The beneficial effects of this invention are: (1) An overhead cable with an intelligent control system of the present invention can monitor the temperature and humidity of the surrounding environment through an intelligent detection cover installed at the end position, thereby judging the operating status of the entire cable. Then, as needed, the external drive module installed on its outside is activated, and heat exchange fluid is injected into the compression flexible guide tube by the external drive module. The heat exchange fluid can expand and adjust the temperature of the compression flexible guide tube, and perform de-icing, snow removal and bird removal operations on the cable surface, thereby improving the safety and durability of the cable and enhancing the level of intelligence. (2) Depending on the location of the external drive module, the driving mode of the heat exchange fluid can be adjusted, and the expansion or contraction of the flexible guide tube can be freely changed, greatly improving the control flexibility. (3) The intelligent detection cover adopts a split structure design and is installed inside the annular mounting groove, which can greatly facilitate installation and maintenance; (4) The entire overhead cable can exchange heat actively or passively to improve the heat dissipation effect; (5) By flipping the external drive module, the flow direction can be changed freely, making control more convenient.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Figure 1 , Figure 2 and Figure 3 The overhead cable shown includes a cable body, which consists of a conductor 1, conductor insulation 2, conductor shield 3, filler 4, inner sheath 5, insulation shield 6 and outer sheath 7 from the inside out. A compression-type flexible guide tube 8 is provided between the inner sheath 5 and the outer sheath 7. Intelligent detection covers 9 are installed at both ends of the cable body, and external drive modules 10 are installed on the side walls of the intelligent detection covers.

[0024] To increase the heat conduction area, the outer surface of the compression flexible guide tube 8 has a lateral metal extension heat dissipation plate 81 that is connected to the inner wall of the outer sheath 7.

[0025] To facilitate end assembly and internal connection, the outer side of the outer sheath 7 is provided with an annular mounting groove for fixing the intelligent detection cover 9 at the connection end. The annular mounting groove has a plurality of side-mounted guide nozzles 82 that are connected to the compression flexible guide tube 8.

[0026] To facilitate separate installation and disassembly, the intelligent detection cover 9 includes an arc-shaped first sealed cover 91 and an arc-shaped second sealed cover 92 fitted inside the annular mounting groove.

[0027] For internal flow guidance, the arc-shaped first sealed cover 91 and the arc-shaped second sealed cover 92 are provided with interconnected internal flow channels 93, and the inner arc-shaped surfaces of the arc-shaped first sealed cover 91 and the arc-shaped second sealed cover 92 are provided with inner connecting holes 94 that are connected to the internal flow channels 93.

[0028] The arc-shaped first sealed cover 91 and the arc-shaped second sealed cover 92 are fixed inside the annular mounting groove by bolts. Then, the inner connecting hole 94 is fitted onto the side-mounted guide nozzle 82 to keep the compressed flexible guide tube 8 connected to the built-in flow channel 93.

[0029] To accommodate the bottom assembly, the bottom of the arc-shaped second sealed cover 92 has a downwardly protruding bottom guide frame 95. The side wall of the bottom guide frame 95 is equipped with a side-mounted support rod 11 for controlling the external drive module 10. The external drive module 10 is movably assembled with the bottom guide frame 95 through an integrally structured guide seat 101.

[0030] The extended end of the side-mounted support rod 11 is movably assembled with the outer side of the external drive module 10.

[0031] To facilitate external flow guidance and adjustment, the external drive module 10 includes an external housing 102 with a flow guide seat 101 on top, centrifugal flow guide blades 103 installed inside the external housing 102, and a detachable liquid storage tank 104 fixed to the side wall of the external housing 102.

[0032] The side-mounted support rod 11 controls the rotation of the external cover 102 by extending and retracting, thereby changing its angle and simultaneously changing the position of the detachable liquid storage tank 104. When in the discharge state, the side-mounted support rod 11 extends, controlling the external cover 102 to be longitudinally positioned, and the detachable liquid storage tank 104 is in the side-mounted position. The heat exchange medium inside the detachable liquid storage tank 104 is discharged by rotating the centrifugal guide vane 103. When in the inlet state, the side-mounted support rod 11 retracts, controlling the external cover 102 to be horizontally positioned, and the detachable liquid storage tank 104 is in the bottom position. The heat exchange medium introduced will flow into the detachable liquid storage tank 104 on this side.

[0033] To improve the elastic reset effect, the removable liquid storage tank 104 is internally elastically equipped with a built-in reset piston 105 and a compression spring 106.

[0034] The built-in reset piston 105 can slide synchronously when the heat exchange medium is discharged or discharged into the removable liquid storage tank 104.

[0035] To facilitate the connection and filtration, the outer side of the external cover 102 is provided with an internally threaded assembly through hole for installing the detachable liquid storage tank 104, and a metal filter screen is installed inside the internally threaded assembly through hole.

[0036] To facilitate monitoring of the external environment, a temperature and humidity sensor controller 96 is installed on the outer surface of the arc-shaped first sealed enclosure 91.

[0037] The temperature and humidity of the surrounding air are monitored by the temperature and humidity sensor controller 96. In low-temperature and high-humidity environments, the cable is prone to freezing. In this case, an internal circulation reciprocating drive is required to electrically heat the heat exchange fluid inside the detachable liquid storage tank 104. Then, the centrifugal guide vanes 103 blow the heat exchange fluid into the built-in flow channels 93 inside the arc-shaped first sealed cover 91 and the arc-shaped second sealed cover 92. The heat exchange fluid is then introduced into the compression flexible guide tube 8 through the side guide nozzle 82 via the inner connecting hole 94 connected to the built-in flow channels 93. At this time, the heat exchange fluid in one end of the detachable liquid storage tank 104 forces the medium inside the compression flexible guide tube 8 into the other end of the detachable liquid storage tank 104. This reciprocating adjustment can improve the active heat exchange effect. The same principle applies in high-temperature environments.

[0038] When the reciprocating flow or simultaneous flow on both sides causes the compression flexible flow tube 8 to expand, the vibration generated during the process can have a certain degree of bird-repelling effect.

[0039] Work process After the cable is installed, the intelligent detection cover 9 is fixed in the annular mounting groove by the arc-shaped first sealed cover 91 and the arc-shaped second sealed cover 92. The inner connecting hole 94 is precisely connected to the side-mounted guide nozzle 82 to ensure the sealing of the guide channel. The detachable liquid storage tank 104 is filled with a sufficient amount of suitable heat exchange fluid, and the built-in heating module is in standby mode. The temperature and humidity sensor controller 96 continuously monitors environmental data, and the control unit analyzes it in real time. The compression flexible guide tube 8 is in a natural contraction state, and the lateral metal extension heat dissipation plate 81 is attached to the inner wall of the outer sheath 7. The entire device is in low-power standby mode, maintaining only the monitoring function.

[0040] The temperature and humidity sensor controller 96 detected that the ambient temperature was ≤0℃ and the humidity was ≥80%, which was determined to be a scenario prone to icing, and sent a de-icing command.

[0041] The control unit activates the heating module inside the detachable storage tank 104 to heat the heat exchange fluid to 40-60℃; at the same time, it commands the side-mounted support rods 11 of the external drive modules 10 on both sides to extend, so that the external cover 102 is placed longitudinally, and the centrifugal guide vanes 103 are activated to generate thrust.

[0042] The high-temperature heat exchange fluid is injected into the compression flexible guide tube 8 through the guide seat 101, bottom guide frame 95, built-in flow channel 93, and side guide nozzle 82. The guide tube expands when heated, and the heat is transferred to the outer sheath 7 through the lateral metal extension heat dissipation plate 81, melting the ice and snow on the surface. The heat exchange fluid in one side storage tank pushes the original low-temperature medium in the guide tube back to the corresponding detachable storage tank 104 through the side guide nozzle 82 and built-in flow channel 93 on the other side, completing a single cycle.

[0043] The control unit controls the heat exchange fluid to circulate repeatedly, and the guide tube expands and contracts repeatedly, vibrating to shed residual ice and snow; when the temperature and humidity sensor controller 96 detects that the ambient temperature is ≥5℃ or the ice and snow have completely melted, the heating module is turned off, the heat exchange fluid cools naturally, and the equipment returns to standby.

[0044] A continuous signal of birds lingering on the cable surface was detected. A vibration sensor was used to help detect birds lingering and a bird-repelling command was sent.

[0045] The control unit commands the side-mounted support rods 11 of the external drive modules 10 on both sides to remain longitudinally positioned, and the centrifugal guide vanes 103 to be activated alternately, driving the heat exchange fluid to flow back and forth in the compression flexible guide tube 8.

[0046] The reciprocating impact of the heat exchange fluid causes the compression flexible guide tube 8 to periodically expand and contract, generating a slight vibration of 10-20Hz. The vibration is transmitted to the surface through the outer sheath 7, disturbing the environment where birds stay. At the same time, the expansion of the guide tube can change the surface morphology of the cable.

[0047] If no stopping signal is detected after 30 seconds of continuous bird deterrence, the centrifugal guide vane 103 stops and the equipment returns to standby mode; if the birds still stop, the bird deterrence process is repeated until the flock leaves.

[0048] When the temperature and humidity sensor controller 96 detects an ambient temperature ≥35℃, or when the internal temperature sensor of the cable detects a temperature ≥60℃, it sends a heat dissipation command.

[0049] The control unit commands the side-mounted support rods 11 of the external drive modules 10 on both sides to retract, so that the external cover 102 is placed horizontally and the detachable liquid storage tank 104 is in a low position; the centrifugal guide vanes 103 rotate at high speed, driving the room temperature heat exchange liquid to be quickly injected into the compression flexible guide tube 8.

[0050] The heat exchange fluid flows inside the guide tube, absorbing the heat transferred from inside the cable, and its temperature rises. The heat is conducted through the wall of the compression flexible guide tube 8 to the lateral metal extension heat dissipation plate 81. The heat dissipation plate increases the contact area with the air, accelerating the heat dissipation. The heated heat exchange fluid returns to the storage tank through the return channel, completing the heat dissipation cycle.

[0051] The external circulation mode can also be opened by using solenoid valves installed on both sides of the external casing 102 and the connection with the detachable liquid storage tank 104 can be closed. In this way, external air can be introduced into the compressed flexible guide pipe 8 for external circulation heat dissipation.
