Description

Technical Field

[0001] This invention relates to the field of power transmission line protection devices, and more particularly to the field of anti-icing devices for high-voltage power transmission lines located in high-altitude, low-temperature and frigid regions, specifically to an anti-icing device for power transmission lines. Background Technology

[0002] Winter icing of power transmission lines is one of the major natural disasters affecting power systems. Power outages and even grid disconnections caused by icing often have extremely serious consequences, and repair work is difficult and time-consuming. Therefore, there is an urgent need for an efficient and convenient de-icing method.

[0003] Some power grid companies currently use electric heating to melt snow or ice using the heat generated by the power lines. This method of snow and ice removal results in significant power loss, and in extremely cold weather, the electric heating is ineffective as the heat generated by the power lines is quickly lost. Other regions rely on manual snow and ice removal, which requires working at high altitudes on slippery power lines, making the work environment extremely harsh and dangerous. Mechanical de-icing using ice-breaking devices is another option. These devices are installed on power transmission lines manually or by drones and remotely controlled to remove ice. However, this method is not widely used because thin ice is not particularly necessary, while thick ice is difficult to remove effectively and has low efficiency. It is also ineffective in areas with thick ice, thus limiting the widespread application of mechanical de-icing methods.

[0004] In summary, given the current technology, de-icing operations are always inconvenient due to the high altitude of power transmission lines, and efficient removal of ice once it forms is difficult. However, de-icing of power transmission lines in frigid regions is one of the key power protection tasks. Therefore, a more effective solution is needed. Summary of the Invention

[0005] To address the problem of existing power transmission lines being subjected to high pressure on power lines and towers due to icing in frigid regions, which can easily lead to power outages or even grid disconnection, this application provides an anti-icing device for power transmission lines. This device treats power transmission lines before icing occurs, preventing the problem of thick, hard ice that is difficult to remove after icing. This invention, through research on the icing process of existing power transmission lines, reveals two states in the initial stage of icing. The first state is caused by raindrops adhering to the transmission lines during rainy weather, which gradually freeze over time, accumulating layer by layer until the ice becomes thick and difficult to remove. The second state is snow accumulation. Because the temperature of snowflakes near the transmission lines is lower, ice slowly forms on the surface of the transmission lines and adheres to them, resulting in icing. Once icing forms, the surface area of ​​the transmission lines continuously increases, supporting more snow accumulation and thus exacerbating the icing problem.

[0006] Research on the icing state of power transmission lines reveals that the simplest way to solve the icing problem is to intervene in the early stages before icing occurs. Since rain and snow have a much lower adhesion to power transmission lines than solidified ice, timely removal of rain and snow residue on the power transmission lines is an effective way to prevent icing.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: An anti-icing device for power transmission lines includes a vibration device and clamping bars evenly distributed around the vibration device and connected to the vibration device for clamping the transmission line. The vibration device includes an actuator for generating vibration and a control unit for supplying power to the actuator and sending drive signals. The control unit includes a CT power-taking circuit installed on the power transmission line to generate induced current. The CT power-taking circuit is also connected to a DC-DC converter circuit that operates at a wide voltage, as well as an energy storage module for filtering, voltage regulation, and energy storage. The energy storage module is electrically connected to the actuator and the control module, respectively. The control module is connected to a sensing module for acquiring the temperature of the power transmission line and a communication module for receiving wireless signals.

[0008] Preferably, the vibration device includes a housing structure, and the actuator is detachably and fixedly mounted on the housing structure. The actuator includes a motor, a gearbox driven by the motor output shaft, and a vibratory disc driven by the gearbox to generate vibration through rotation. The vibratory disc is a single vibration structure, preferably using the eccentric rotation of a single component to generate strong vibration, thereby reducing the failure rate during operation.

[0009] Furthermore, in order to maximize the instantaneous vibration frequency and amplitude, as shown in the attached figure of the instruction manual, the vibratory disk housing is fixedly connected to the body structure, and the flying disk is rotatably set inside the vibratory disk housing. The flying disk has multiple slides evenly arranged radially for sliding the counterweight. An electromagnet is fixedly installed in one of the slides near the center of the flying disk. When the electromagnet is energized, the electromagnet and the counterweight attract each other. The design of the frisbee described in this application is one of the main technical improvements. The technical solution it adopts is different from the vibration generated by the rotation of the existing eccentric wheel. It mainly uses a critical value set in the structural state. When the centrifugal force generated by the rotation speed reaches the preset centrifugal force, the frisbee will rotate eccentrically and generate strong vibration instantly. When the rotation speed does not reach the preset speed of the system, the centrifugal force of the counterweight is not enough to overcome the attraction of the electromagnet. In this case, it will always be located near the electromagnet. In this state, the center of gravity of the entire frisbee is balanced. The frisbee only needs a small torque to drive its rotation. Under the action of inertia and continuous driving force, the rotation speed of the frisbee will become faster and faster until the centrifugal force of the counterweight becomes too large to overcome the attraction of the electromagnet and slide along the slide to the position near the edge of the frisbee. Because each electromagnet has a different output power and attraction force, when the counterweights located close to the same side detach from the electromagnets, the entire disc becomes eccentric. This uneven center of gravity causes significant vibration; the faster the rotation speed, the greater the frequency and amplitude of the vibration. This vibration drives the entire anti-icing device, causing the power transmission line to vibrate, thus dislodging rain and snow adhering to the line and resolving the icing problem. This invention can operate continuously or intermittently, meeting the anti-icing requirements of different temperature environments. It is safe, reliable, efficient, and practical. No human intervention is required, avoiding the risks of working at heights and electric shock.

[0010] To better adapt to existing multi-split transmission lines and effectively improve the rigidity of vibration propagation, the clamping rod preferably includes a screw connected to the vibration device, a first connecting rod threadedly connected to the screw, an anti-loosening nut on the screw to maintain the relative position of the first connecting rod and the screw, and a clamping mechanism at the other end of the first connecting rod for clamping the transmission line. To simplify the result, the present invention installs the CT power supply circuit at either end of the clamping mechanism, thereby further simplifying the structure, improving the overall integrity of the device, and structurally and functionally replacing the spacer bar of the existing high-voltage split line, while fully meeting the continuous power supply requirements of the present invention. Of course, the above design is only a preferred design of the present invention; other separate installation methods can also be used, which are not listed here.

[0011] Furthermore, the clamping mechanism includes a first clamping part fixedly connected to the first connecting rod, and a second clamping part hinged to the first clamping part and forming an annular structure for wrapping and / or clamping the power transmission line. A second connecting rod adapted to the first connecting rod is fixedly connected to the free end of the second clamping part. The first and second connecting rods are fixed together by a first locking device. The function of the first locking device is to fix the clamping rod to the power transmission line, ensuring the firmness of the connection between the entire assembly and the power transmission line.

[0012] Furthermore, to reduce vibration losses, a second locking device is provided on the first clamping part and / or the second clamping part in this invention. The second locking device passes through the first clamping part and / or the second clamping part and is also connected to an arc-shaped pressure plate for compressing the transmission line. After the transmission line is clamped and locked, the second locking device can effectively increase the rigid connection between the transmission line and the clamping mechanism, eliminate contact gaps, and avoid vibration losses caused by poor contact or gaps during vibration transmission, thereby reducing the preventive effect of anti-icing.

[0013] To facilitate installation and ensure the device can withstand rain and snow at high altitudes, the housing structure includes a first housing, a first support, a second support, a third support, and a second housing arranged sequentially. The first and third supports are symmetrically distributed on both sides of the second support and are fixedly connected by multiple second fasteners evenly distributed around the edges. The first and second housings are respectively distributed on both sides of the first and third supports and are interlocked with each other. Multiple first fasteners for penetrating the entire vibration device are fixedly connected to the inner surface of the first housing and are threadedly connected to nuts provided on the outer surface of the second housing.

[0014] Furthermore, in order to accommodate the gaps between different split lines and enable adaptive installation, preferably, the clamping rod also includes a sleeve that is fixedly connected to the screw and hinged to the second fastener.

[0015] To improve the filtering and discharging capabilities of this invention and ensure normal operation of the driving motor in extremely cold environments, the energy storage module includes a battery for storing electricity and a supercapacitor for filtering and discharging, housed within the vibration device. Beneficial effects

[0016] 1. This invention can effectively adjust the intensity, amplitude and frequency of vibration by setting an adjustable centrifugal disc. The vibration generated by the rotation of the disc causes rain and snow attached to the power transmission line to fall off in time, avoiding the deposition on the power transmission line and the formation of ice.

[0017] 2. Throughout the entire operation of this invention, no human intervention is required. It can carry out closed-loop operation through autonomous temperature sensing. Since it uses CT for power, there is no need to worry about power interruption. At the same time, compared with existing heating and de-icing methods, its energy consumption is greatly reduced.

[0018] 3. This invention can replace the existing damping spacer bar, and solves the technical problems of transmission lines whipping each other without increasing the load on the transmission line. Attached Figure Description

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] In the description of this application, it should be noted that the use of terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships commonly used when the product is in use.

[0035] This embodiment provides, as follows: Figure 1 , Figure 3 and Figures 7-8 The illustrated anti-icing device for power transmission lines includes a vibration device 200 and clamping rods 100 uniformly distributed around and connected to the vibration device 200 for clamping the power transmission line. The vibration device 200 includes an actuator for generating vibration and a control unit for supplying power to the actuator and sending drive signals. The control unit includes a current collector circuit (CT) installed on the power transmission line for generating induced current. The CT circuit is also connected to a wide-voltage DC-DC converter circuit and an energy storage module for filtering, voltage regulation, and energy storage. The energy storage module is electrically connected to the actuator and the control module. The control module is connected to a sensing module for collecting the temperature of the power transmission line and a communication module for receiving wireless signals.

[0036] Working principle: Clamping rods 100 clamp one-to-one onto the multi-branched transmission lines, fixing the vibration device 200 to the transmission lines. In this case, it acts as a regular spacer, preventing whipping between the multi-branched lines. A CT power-taking circuit is installed on the transmission lines to induced power, and then supplies power according to the required voltage for the vibration device 200. The CT power-taking circuit rectifies and filters the induced current, then adjusts the voltage through a DC-DC converter circuit to obtain a power supply voltage matching the vibration device 200. The converted current is stored in an energy storage module, ensuring that the normal operation of the invention is not affected when the power transmission line is unstable. The sensing module includes a temperature sensor for collecting ambient temperature. When the actual collected temperature is lower than or equal to the temperature preset by the control module, such as 1°C, the control module sends a start command to the actuator. The actuator then starts working, generating vibration to cause rainwater or accumulated snow on the transmission lines to fall off, achieving the technical effect of preventing icing. See details. Figure 7As shown, an existing controllable wireless communication module is used to enable manual control outside the automatic closed-loop operating mode, thereby improving the practicality of this embodiment. It is worth noting that the wireless communication module and control technology are currently mature technologies; conventional 4G or radio frequency communication control can be used. This part is not an improvement on this embodiment and will not be elaborated upon here. Example 2:

[0037] This embodiment is based on Embodiment 1, and further incorporates the appendix to the specification. Figures 1-7 As shown, the vibration device 200 includes a housing structure, and the actuator is detachably and fixedly mounted on the housing structure. The actuator includes a motor 29, a gearbox 30 driven by the output shaft of the motor 29, and a vibratory disc that generates vibration by rotation and is driven by the gearbox 30. The vibratory disc is a single vibration structure, and preferably uses the eccentric rotation of a single component to generate strong vibration, reducing the failure rate during operation.

[0038] In this embodiment, in order to maximize the instantaneous vibration frequency and amplitude, the following steps are taken in conjunction with the appendix to the specification. Figure 4As shown, the vibratory feeder housing 31 is fixedly connected to the housing structure, and the fly disk 33 is rotatably disposed inside the vibratory feeder housing 31. The fly disk 33 is provided with multiple slides 34 evenly arranged radially for sliding the counterweight 36. An electromagnet 35 is fixedly installed in one end of any slide 34 near the center of the fly disk 33. When the electromagnet 35 is energized, the electromagnet 35 and the counterweight 36 attract each other. The design of the frisbee 33 described in this application is one of the main technical improvements. The technical solution it adopts is different from the vibration generated by the rotation of the existing eccentric wheel. It mainly uses a critical value set in the structural state. When the centrifugal force generated by the rotation speed reaches the preset centrifugal force, the frisbee 33 will rotate eccentrically and generate strong vibration instantly. When the rotation speed does not reach the preset speed of the system, the centrifugal force of the counterweight 36 is insufficient to overcome the attraction of the electromagnet 35. In this state, the center of gravity of the entire frisbee 33 is balanced. The frisbee 33 only needs a small torque to drive its rotation. Under the action of inertia and continuous driving force, the rotation speed of the frisbee 33 will become faster and faster until the centrifugal force of the counterweight 36 becomes larger and larger, overcomes the attraction of the electromagnet 35, and slides along the slide 34 to the position near the edge of the frisbee 33. Because each electromagnet 35 has a different output power and attraction force, when the counterweight 36 located near the same side detaches from the electromagnet 35, the entire flying disc 33 is in an eccentric state. This uneven center of gravity causes significant vibration; the faster the rotation speed, the greater the frequency and amplitude of the vibration. This, in turn, causes the entire anti-icing device to vibrate the power transmission line, causing rain and snow adhering to the power transmission line to fall off promptly, thus solving the problem of icing. This invention can achieve both continuous and intermittent operation, meeting the anti-icing requirements of different temperature environments. It is safe, reliable, efficient, and practical. No personnel intervention is required, avoiding the risks of working at heights and electric shock. Figures 5-6 As shown in the figure, this embodiment illustrates the structure of a non-adjustable frisbee 33. When the frisbee 33 is stationary or at low speed, its center of gravity is uniform. When it rotates at high speed, the counterweight 36 disengages from the electromagnet 35, achieving the following... Figure 6 The frisbee 33 has only three counterweights 36, with other parts maintaining the same weight distribution as the frisbee 33. This ensures that the center of gravity of the entire frisbee 33 is balanced at low speeds or when stationary. When the frisbee 33 rotates at high speed, only the three counterweights 36 generate centrifugal force. This design eliminates the need for separate management of different electromagnets 35, avoiding the circuitry and structural design required for individual management of the operating current of each electromagnet 35, thus simplifying the management of the electromagnets 35. Alternatively, each electromagnet 35 can be controlled with a separate electrical signal, resulting in different center of gravity offsets and vibration states for the same frisbee 33.

[0039] To better adapt to existing multi-split transmission lines and effectively improve the rigid propagation of vibration, in conjunction with the instruction manual appendix... Figures 1-2 As shown, it includes a screw 2 connected to the vibration device 200, a first connecting rod 4 threadedly connected to the screw 2, an anti-loosening nut 3 provided on the screw 2 for maintaining the relative position of the first connecting rod 4 and the screw 2, and a clamping mechanism provided at the other end of the first connecting rod 4 for clamping the power transmission line.

[0040] Furthermore, the clamping mechanism includes a first clamping part 5 fixedly connected to the first connecting rod 4, and a second clamping part 6 hinged to the first clamping part 5 and forming an annular structure for wrapping and / or clamping the power transmission line. A second connecting rod 7 adapted to the first connecting rod 4 is fixedly connected to the free end of the second clamping part 6. The first connecting rod 4 and the second connecting rod 7 are fixed together by a first locking device 8. The function of the first locking device 8 is to fix the clamping rod 100 to the power transmission line, ensuring the firmness of the connection between the entire assembly and the power transmission line.

[0041] Furthermore, to reduce vibration losses, preferably, a second locking device 9 is provided on the first clamping part 5 and / or the second clamping part 6. The second locking device 9 passes through the first clamping part 5 and / or the second clamping part 6 and is also connected to an arc-shaped pressure plate 10 for compressing the transmission line. After the transmission line is clamped and locked, the second locking device 9 can effectively increase the rigid connection between the transmission line and the clamping mechanism, eliminate contact gaps, and avoid vibration losses caused by poor contact or gaps during vibration transmission, thereby reducing the probability of icing and achieving the technical effect of effectively preventing icing.

[0042] To facilitate installation and ensure the device's stability during high-altitude rain and snow, the housing structure comprises a first housing 21, a first support 23, a second support 24, a third support 26, and a second housing 27 arranged sequentially. The first support 23 and the third support 26 are symmetrically distributed on both sides of the second support 24 and are fixedly connected by multiple second fasteners 25 evenly distributed around the edges. The first housing 21 and the second housing 27 are respectively distributed on both sides of the first support 23 and the third support 26 and are interlocked. Multiple first fasteners 22, which penetrate the entire vibration device 200, are fixedly connected to the inner surface of the first housing 21 and are threadedly connected to nuts 28 on the outer surface of the second housing 27. In this embodiment, sealing material is preferably used between the multiple housings and supports to prevent long-term high-altitude rain and snow erosion from affecting the stability of the internal structure.

[0043] Furthermore, in order to accommodate the gaps between different split lines and achieve adaptive installation, preferably, the clamping rod 100 also includes a sleeve 1 that is fixedly connected to the screw 2 and hinged to the second fastener 25.

[0044] In order to improve the filtering and discharging capabilities of the present invention and ensure that the motor 29 can work normally in extremely cold environments, the energy storage module includes a battery 32 for storing electricity and a supercapacitor for filtering and discharging, which are installed in the vibration device 200.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
