Description

Technical Field

[0001] The present invention relates to the technical field of wire deicing, and more specifically, to a wire deicing device in the early stage of ice formation. The present invention also relates to a wire deicing system in the early stage of ice formation, including the above-mentioned wire deicing device in the early stage of ice formation. The present invention further relates to a wire deicing method in the early stage of ice formation, which is applied to the above-mentioned wire deicing device in the early stage of ice formation and / or the above-mentioned wire deicing system in the early stage of ice formation. Background Art

[0002] In the power system, the problem of icing on the transmission and distribution lines has always been a major safety hazard. Icing not only reduces the mechanical strength of the conductors, but may also cause the conductors to dance or the ice to fall off, which in turn generates impact loads and causes serious damage to the lines. In addition, if the insulator strings of the transmission lines are overly covered with ice or bridged by ice, the insulation performance will be greatly reduced, which can easily lead to line failures and affect the stable operation of the power system.

[0003] Common types of icing include rime, mixed rime, soft rime and hoarfrost. Rime is mainly formed during freezing rain in low-altitude areas, with low density and short duration; while mixed rime is formed on the basis of meeting the conditions for rime, due to high moisture content in the air and fast air flow, with high density and rapid development, which is more harmful to wires. Especially in winter and spring, in areas with humid climate, the problem of wire icing is particularly prominent.

[0004] Most of the de-icing methods currently used are manual de-icing. However, if the line is located in a mountainous area, it is difficult for personnel to reach the tower, and personnel and vehicles cannot reach it, which will affect the progress of line de-icing and also pose certain safety risks. There is also the widely used drone "sword" for snow removal at high altitudes. This method also has certain limitations. Due to the promulgation of new drone policies, many areas have restricted altitudes and require application for airspace, or when encountering extreme weather, it will affect the progress of line de-icing. At the same time, the hanging iron rods may also cause certain damage to the wires due to the impact of wind. In addition, if you encounter a compact tower or a line on the same tower, the distance between the wire and the ground wire is too close, it is very likely that the drone will be suspended on the ground wire due to improper operation, which will cause problems when the problem is not solved.

[0005] In summary, how to remove the snow or thin ice on the surface of the conductor in the early stage of ice formation is a problem that needs to be solved urgently by technicians in this field. Summary of the invention

[0049] The core of the present invention is to provide a conductor deicing device in the early stage of ice formation.

[0050] Another core of the present invention is to provide a conductor deicing system in the early stage of ice formation, including the above-mentioned conductor deicing device in the early stage of ice formation.

[0051] Another core of the present invention is to provide a method for deicing wires in the early stage of ice formation, which is applied to the above-mentioned device for deicing wires in the early stage of ice formation and / or the above-mentioned system for deicing wires in the early stage of ice formation.

[0052] Please refer to Figures 1 to 3 .

[0053] First of all, it should be explained that the current distribution of conductors in the transmission line is usually two conductors on the top and two conductors on the bottom. The fixed conductor 8 mentioned in this application is any two conductors on the same horizontal plane. The deicing conductor 8 mentioned in this application is any conductor that has a certain height difference with the fixed conductor 9. When deicing of multiple conductors is required, multiple devices can be set up for staggered arrangement.

[0054] The wire deicing device in the initial stage of ice forming provided by the present invention includes a base 1, a shell 2, a connecting shaft 3, an eccentric wheel 4 and a driving mechanism 5. The base 1 is fixedly arranged on two fixed wires 9 with a height difference on the sides of the deicing wire 8, the shell 2 is fixedly arranged on the base 1, the shell 2 is a hollow structure, the connecting shaft 3 is fixedly arranged in the shell 2, the eccentric wheel 4 is rotatably connected with the connecting shaft 3 so that the eccentric wheel 4 slides along the inner wall of the shell 2, the eccentric wheel 4 is sleeved on the deicing wire 8, the driving mechanism 5 is arranged in the shell 2, and the driving mechanism 5 is used to drive the eccentric wheel 4 to rotate along the connecting shaft 3.

[0055] Specifically, fixing any end of the base 1 in the height direction to two fixed wires 9 with a height difference beside the deicing wire 8 keeps the device stable, and at the same time, the shell 2 is covered on the deicing wire 8, and at the same time, a through hole is opened on the shell 2 to facilitate the displacement of the deicing wire 8 during the vibration process. A connecting shaft 3 is fixedly arranged in the shell 2, and the eccentric wheel 4 is rotatably arranged on the connecting shaft 3 so that the eccentric wheel 4 can reciprocate. The deicing wire 8 is passed through the eccentric wheel 4 and is different from the position of the connecting shaft 3. The position of the deicing wire 8 is specifically adjusted according to the required vibration frequency intensity. The driving mechanism 5 drives the eccentric wheel 4 to rotate along the connecting shaft 3 in the shell 2, and then drives the deicing wire 8 on the eccentric wheel 4 to move, giving the deicing wire 8 a flexible impact, generating a certain frequency of vibration, similar to an electric sieve, a mobile phone vibration, etc., which can vibrate off the snow or thin ice on the surface of the deicing wire 8.

[0056] The above-mentioned wire deicing device controls the driving mechanism 5 in the initial stage of ice formation to drive the eccentric wheel 4 to rotate along the connecting shaft 3 in the shell 2, thereby driving the deicing wire 8 on the eccentric wheel 4 to move, giving the deicing wire 8 a flexible impact, generating a vibration of a certain frequency, similar to an electric sieve, mobile phone vibration, etc., which can vibrate off the snow or thin ice on the surface of the deicing wire 8. This vibration frequency is different from high-frequency vibration and can be equivalent to the inherent self-vibration frequency of the wire, causing the wire to resonate. After clearing the snow in a short time, the energy will be consumed through the anti-vibration hammer or damping wire, and the wire can return to its original state, reducing the harm of resonance to the wire, thereby achieving the effect of controlling the early stage of ice formation.

[0057] The conductor deicing device at the initial stage of ice formation provided by the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] In a specific embodiment, reference Figures 1 to 3 The driving mechanism 5 includes a traction member 51 and a driving motor (not shown in the figure). A sliding groove 52 is opened in the housing 2 along the radial direction of the connecting shaft 3. The traction member 51 can slide along the sliding groove 52. One end of the traction member 51 is rotatably connected to the eccentric wheel 4. The driving motor is used to drive the traction member 51 to slide along the sliding groove 52.

[0059] Specifically, the traction member 51 is slidably disposed in the slide groove 52, and is driven by a driving motor to slide along the slide groove 52. During the sliding process of the traction member 51, the eccentric wheel 4 is driven to move along the connecting shaft 3, and the deicing wire 8 on the eccentric wheel 4 moves around the connecting shaft 3 along with the movement of the eccentric wheel 4, thereby generating a vibration of a certain frequency domain for the deicing wire 8, thereby realizing the driving of the eccentric wheel 4. At the same time, the slide groove 52 has a stroke limit, and a limit block (not shown in the figure) is correspondingly arranged inside the slide groove 52 to ensure that the traction member 51 can reciprocate within the stroke limit.

[0060] In some other embodiments, the driving mechanism 5 may also adopt a structure that converts rotational motion into linear motion, or other structures that can achieve reciprocating movement of one end of the traction member 51 in the vertical direction.

[0061] Furthermore, the traction member 51 includes a slider 511 and a connecting rod 512. The slider 511 is slidably disposed in the slide groove 52. One end of the connecting rod 512 is rotationally connected to the surface of the eccentric wheel 4. The side of the connecting rod 512 away from the eccentric wheel 4 is rotationally connected to the slider 511.

[0062] Specifically, the slider 511 is slidably set in the slide groove 52, and the driving motor can drive the slider 511 to slide along the slide groove 52. During the sliding process of the slider 511, the connecting rod 512 is displaced in the vertical direction as the slider 511 moves. At the same time, the connecting rod 512 cooperates with the connecting shaft 3, and the swing of the connecting rod 512 drives the eccentric wheel 4 to rotate repeatedly along the connecting shaft 3, thereby realizing the driving of the eccentric wheel 4.

[0063] It should also be noted that the reference Figures 1 to 3 A protrusion is provided at one end of the connecting rod 512 close to the eccentric wheel 4, and a groove matching with the protrusion is provided at one side of the eccentric wheel 4 close to the connecting rod 512. The protrusion is rotatably arranged in the groove, and the protrusion does not separate from the groove.

[0064] Optionally, a distance sensor is provided on the connecting rod 512 to sense the distance between the connecting rod 512 and the de-icing wire 8, and the distance sensor is electrically connected to the driving mechanism 5. After the distance sensor senses the proximity of the de-icing wire 8, it transmits an electrical signal to the driving mechanism 5 and controls the driving mechanism 5 to reverse, thereby reciprocating and causing the de-icing wire 8 to vibrate, thereby preventing the connecting rod 512 from contacting the de-icing wire 8 during movement.

[0065] Specifically, the protrusion cooperates with the groove, and one end of the groove is slidably clamped on the protrusion. In the process of the connecting rod 512 driving the eccentric wheel 4 to rotate, in order to ensure that the two will not get stuck during the rotation process, the connecting rod 512 and the eccentric wheel 4 can produce a certain relative rotational displacement under the cooperation of the protrusion and the groove, thereby ensuring the normal operation of the eccentric wheel 4.

[0066] Optional, reference Figure 3 The connecting rod 512 can also be connected to the eccentric wheel 4 through a connecting rod structure, that is, one end of the connecting rod structure is rotationally connected to the shaft of the eccentric wheel 4, and the other end is rotationally connected to the connecting rod 512, so that the connecting rod 512 drives the eccentric wheel 4 to rotate along the connecting shaft 3.

[0067] Based on any of the above embodiments, Figures 1 to 3 , both sides of the bottom of the base 1 are provided with fixing grooves, the fixing wire 9 is located in the fixing groove, and the fixing components ( Figure 1 Not shown, Figure 3 ), the fixing assembly is used to fix the fixed wire 9 in the corresponding fixing groove.

[0068] Specifically, a wire inlet groove is provided on one side of the bottom of the fixing groove, and the fixing wire 9 enters the fixing groove from the wire inlet groove, and the fixing wire 9 is fixed in the fixing groove by a fixing assembly to ensure the stability of the device during use.

[0069] Furthermore, the fixing assembly includes a cylinder arranged on the base 1, and a fixing ring is fixedly arranged at the end of the output rod of the cylinder, and the fixing ring moves toward the fixing wire 9 in the fixing groove, so that the fixing wire 9 is fixed and limited in the fixing groove.

[0070] Specifically, the cylinder is arranged on the base 1, and the telescopic rod of the cylinder extends out and is located in the fixed groove, and is arranged along the extension direction of the fixed groove. A fixing ring is arranged on the telescopic rod, and the fixing ring forms a clamp shape with one side of the bottom of the fixed groove to fix the fixed wire 9.

[0071] It should also be noted that a rubber skin is also provided between the fixing ring and the fixing wire 9 to protect the fixing wire 9 , and an aluminum tape may be added to further enhance the protection of the fixing wire 9 .

[0072] Based on any of the above embodiments, Figures 1 to 3 A holding structure 10 is provided on the upper side of the shell 2 away from the deicing wire 8. The holding structure 10 is used to hold the wire parallel to the deicing wire 8, thereby further increasing the overall stability of the device.

[0073] The conductor deicing system in the early stage of ice formation provided by the present invention includes any one of the above-mentioned conductor deicing devices in the early stage of ice formation, a power supply module 6, a signal receiving module 7, a remote control platform and a line monitoring device, the power supply module 6 is used to supply power to the driving mechanism 5, the signal receiving module 7 is arranged in the shell 2, the signal receiving module 7 is used to receive a remote control signal to control the start and stop of the driving mechanism 5, the remote control platform is used to send a remote control signal, and the line monitoring equipment is used to monitor the snow accumulation or thin ice conditions of the transmission line in real time.

[0074] Specifically, the power supply module 6 can adopt the power supply method of the distributed fault diagnosis device (such as Figure 2 As shown in the figure), the principle of electromagnetic induction is used to obtain electricity, and the driving mechanism 5, the signal receiving module 7 and other devices are all electrically connected. It can also be powered by solar panels or CT. With the help of the deicing wire 8 of the line monitoring equipment, monitoring is carried out. When the deicing demand is met, the remote control platform is used to send a remote control signal. At the same time, the wire deicing device receives the remote control signal with the help of the signal receiving module 7, and then controls the start and stop of the driving mechanism 5 to achieve deicing and stopping of the deicing wire 8.

[0075] The above-mentioned conductor deicing system in the early stage of ice formation includes an efficient power supply module, a signal receiving module, a remote control platform and a line monitoring device, forming a complete intelligent deicing management system. The system can monitor the snow or thin ice on the transmission line in real time to ensure accurate grasp of the ice condition. Once the need for deicing is detected, the remote control platform will quickly send a remote control signal, which will be received by the conductor deicing device through the signal receiving module, and then control the precise start and stop of the driving mechanism to achieve rapid and effective deicing of the deicing conductor 8. The power supply module of the system adopts a variety of reliable power supply methods, such as the power supply method of the distributed fault diagnosis device, solar panel power supply or CT power supply, etc., to ensure that the deicing device can provide stable and continuous power support under various environmental conditions. At the same time, the coordinated use of the signal receiving module and the remote control platform allows the operator to remotely control and monitor the deicing device away from the site, greatly improving the efficiency and safety of the deicing operation. In general, the system has significant advantages of intelligence, efficiency, flexibility and remote controllability. It can effectively meet the de-icing needs of transmission lines in the early stages of ice formation and provide strong guarantees for the stable operation of the power system.

[0076] Based on any of the above embodiments, the conductor deicing system in the initial stage of ice formation is integrated with the Beidou displacement monitoring function. After the deicing device is started with the help of the remote control platform, the deicing device vibrates and de-ices the deicing conductor 8. The vibration condition of the deicing conductor 8 (including the displacement change values ​​such as the horizontal position and the vertical position per unit time) is transmitted to the remote control platform with the help of the Beidou displacement monitoring function. The remote control platform adjusts the vibration amplitude of the deicing conductor 8 by changing the rotation speed of the eccentric wheel 4 in the deicing device to achieve the specified vibration amplitude.

[0077] Based on any of the above embodiments, the line monitoring device includes an image acquisition module for acquiring real-time images of the transmission line and forming monitoring data, and the remote control platform includes a data processing module for processing the monitoring data from the line monitoring device and generating corresponding remote control signals.

[0078] Specifically, the image acquisition module can capture images of the transmission line and its surrounding environment in real time, ensuring that the operation and maintenance personnel can grasp the line status at any time. By processing the monitoring data, the remote control platform can promptly detect line anomalies, such as broken wires, hanging foreign objects, and trees growing too close, and issue early warning information so that the operation and maintenance personnel can take quick measures to avoid failures. This not only improves the reliability and safety of the power system, but also reduces the operation and maintenance costs for power companies and improves the operation and maintenance efficiency.

[0079] Based on any of the above embodiments, the conductor deicing system in the early stage of ice formation provided by the present invention also includes a temperature detection module for real-time monitoring of ambient temperature and transmitting data to a remote control platform.

[0080] Specifically, the temperature detection module can monitor the temperature of the environment where the transmission line is located in real time and transmit the data to the remote control platform. This function enables operation and maintenance personnel to accurately grasp the real-time temperature conditions of the environment where the line is located, and then determine whether it is necessary to start the de-icing device. Especially in the early stage of ice formation, temperature changes have an important impact on the formation and development of ice. By monitoring the ambient temperature in real time, operation and maintenance personnel can more accurately determine when to start the de-icing device to avoid energy waste or poor de-icing effect caused by starting too early or too late.

[0081] It should also be noted that the wire deicing system in the initial stage of ice formation is also integrated with a closed-loop control system, which presets a maximum value (xmax, ymax) for the vibration amplitude of the deicing wire 8. When the vibration amplitude value (x, y) of the deicing wire 8 in a unit time exceeds the preset value (xmax, ymax), the driving mechanism 5 in the deicing device is controlled to automatically stop working, so that the vibration amplitude of the deicing wire 8 is gradually reduced. This setting can effectively avoid the situation where the deicing wire 8 is damaged due to excessive vibration amplitude of the deicing wire 8 during the operation of the deicing device.

[0082] The present invention provides a method for deicing a conductor in the early stage of ice formation, which is applied to any of the above-mentioned devices for deicing a conductor in the early stage of ice formation and / or any of the above-mentioned systems for deicing a conductor in the early stage of ice formation. The deicing method comprises:

[0083] Real-time monitoring of the status of the transmission line, including the snow or thin ice on the deicing conductor 8, to confirm whether the deicing conditions are met;

[0084] The control driving mechanism 5 drives the eccentric wheel 4 to reciprocate along the connecting shaft 3, so that the deicing wire 8 on the eccentric wheel 4 vibrates, thereby removing the snow or thin ice on the deicing wire 8;

[0085] The state of the transmission line is monitored, and when there is no snow or thin ice on the deicing wire 8, the driving mechanism 5 is controlled to stop.

[0086] Specifically, a line monitoring device, such as an image acquisition module, is used to monitor the state of the transmission line in real time, especially the snow or thin ice on the deicing conductor 8. The monitoring data is processed and analyzed by the data processing module of the remote control platform to determine whether the current state meets the deicing conditions. When it is confirmed that the deicing conditions are met, the remote control platform sends a remote control signal to the conductor deicing device. After the signal receiving module receives the signal, the control driving mechanism starts. The driving mechanism drives the eccentric wheel to reciprocate along the connecting shaft, and this movement causes the deicing conductor 8 located on the eccentric wheel to resonate. This vibration can effectively shake off the snow or thin ice on the deicing conductor 8, thereby achieving the deicing effect. During the deicing process, the line monitoring device continues to be used to monitor the state of the transmission line. When it is confirmed that there is no snow or thin ice on the deicing conductor 8, the remote control platform sends a remote control signal again. After the signal receiving module receives the signal, the control driving mechanism stops working and ends the deicing process.

[0087] The above-mentioned conductor deicing method in the early stage of ice formation ensures that the deicing process can be started in time at the early stage of ice formation through real-time monitoring and precise control, so as to avoid more serious consequences caused by ice accumulation. The flexible impact generated by the eccentric wheel can effectively remove snow and thin ice, and improve the deicing efficiency. The entire deicing process realizes remote control and intelligent management, reducing the frequency and difficulty of manual intervention. It improves the operation and maintenance efficiency and reduces the operation and maintenance costs. At the same time, real-time monitoring and timely deicing can avoid transmission line failures and safety accidents caused by ice accumulation. It improves the stability and safety of the power system. In addition, the method completes deicing before ice formation by timely removing snow and thin ice, reducing the damage of ice to the transmission line and deicing device. In summary, the conductor deicing method in the early stage of ice formation provided by the present invention has multiple advantages such as high efficiency, energy saving, intelligence, safety and extended equipment life, and provides a strong guarantee for the stable operation of the power system.

[0088] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
