Description

Technical Field

[0001] This invention relates to the field of overhead line de-icing technology, and more specifically, to an automatic de-icing device for overhead lines. Background Technology

[0002] Currently, most power grid lines are overhead lines. In the south, freezing rain is frequent in winter, often causing overhead lines to be overloaded and break, or even towers to collapse.

[0003] Existing technologies include on-site, offline de-icing methods such as using drones to break ice, pulling wires to shake ice, and vibrators to remove ice, as well as remote, online methods such as DC de-icing. All of these methods have some drawbacks, as follows: Offline de-icing requires personnel to go to the site for construction. Frozen road conditions and ice falling from high-voltage lines pose serious threats to the personal safety of construction workers. Generally, overhead lines are long, and once they are frozen, vehicles cannot pass, and it is difficult for people to walk on mountain roads. This results in a long offline de-icing construction period, which often leads to the breakage of overhead lines that are scheduled for later construction. In order to ensure construction safety, offline de-icing is generally carried out when the lines are not energized. Due to the long construction period, it requires a long power outage, which affects the quality of power transmission. Online de-icing solutions such as DC de-icing are expensive, consume a lot of energy, and are not economically efficient. They also cause the conductors to heat up by short-circuiting the DC circuit, which can damage the lines. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies in de-icing overhead lines, which cannot simultaneously ensure safety, convenience, and economy. This invention provides an automatic de-icing device for overhead lines that requires no manual intervention, does not require power outages during the de-icing process, and is economical.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An automatic de-icing device for overhead power lines is provided, including: The housing is used to install various components, and the housing is equipped with fasteners for hanging. A wind-powered rotator, which uses wind energy to drive its rotation, is installed outside the housing and located below the housing, with the end of the wind-powered rotator inserted into the housing. A deflector, used for vibration de-icing, is installed inside the box; The suction mechanism is partially installed inside the box and partially installed outside the box, and can move downward under the action of external gravity; A reset mechanism, connected to the suction mechanism, is used for the upward reset of the suction mechanism; The oscillating component can be connected to the wind-powered rotator through the suction mechanism, and under the action of wind energy, it drives the box to vibrate.

[0006] This invention uses fasteners on the outside of the housing to attach it to the overhead power line. The wind turbine can rotate under the action of wind, providing a power source for the entire system. During freezing weather, rainwater freezes and accumulates on the part of the suction mechanism located outside the housing. Under the action of gravity, the suction mechanism will move downward, thereby connecting the oscillating component with the wind turbine. The wind turbine rotates under the action of wind, driving the oscillating component to rotate. During the rotation of the oscillating component, the oscillation will cause the housing to vibrate eccentrically, which in turn will cause the overhead power line to vibrate, causing the ice / ice water mixture on the overhead power line to peel off from the line, achieving a de-icing effect. During non-freezing weather, rainwater will not accumulate on the suction mechanism. Under the action of the reset mechanism, the suction mechanism will not engage, the oscillating component will disengage from the wind turbine, will not rotate, and the overhead power line will not vibrate. This invention requires no manual intervention: it automatically starts after icing without manual monitoring, achieving automatic de-icing of high-voltage overhead lines; it utilizes natural wind power, eliminating the need for an additional power source and solving problems such as the difficulty of obtaining power for high-voltage lines; the overhead lines do not require power outages during the de-icing process, thus not affecting power transmission; moreover, this invention is economical, being a purely mechanical device with a simple structure, no expensive parts, and low cost; it is easy to construct, achieving low-cost and high-efficiency de-icing of overhead lines.

[0007] Further, the engaging mechanism includes a connecting rod, a permanent magnet clutch, a swivel cone, a first rotating shaft, a first bearing, and a second bearing. The connecting rod, the permanent magnet clutch, and the first bearing are all installed inside the housing. The deflector is located in the middle of the connecting rod and is connected to the connecting rod through the first bearing. There are at least two swivel cones located outside the housing. The two swivel cones are symmetrically arranged with the first bearing as the center, or multiple swivel cones are evenly distributed with the first bearing as the center. The number of reset mechanisms and the number of the first rotating shafts are equal to the number of swivel cones. One swivel cone, one first rotating shaft, and one reset mechanism correspond to each other. The swivel cone is connected to the connecting rod through the first rotating shaft. The reset mechanism is sleeved outside the first rotating shaft and its end abuts against the housing. The permanent magnet clutch includes a first engaging part and a second engaging part. The first engaging part is connected to the deflector, and the second engaging part is connected to the wind turbine. The wind turbine is connected to the housing through the second bearing.

[0008] The connecting rod connects the leak cone and the eccentric component. During freezing weather, the leak holes of the leak cone are blocked by ice, and rainwater accumulates inside the leak cone, forming a weight. Under the action of gravity, the overcoming reset mechanism drives the connecting rod to sink. The first engagement part of the permanent magnet clutch installed on the connecting rod sinks along with it. When the clearance of the permanent magnet clutch reaches a certain distance, it engages with the second engagement part of the permanent magnet clutch installed on the wind turbine. The wind turbine connects with the eccentric component, thereby driving the eccentric component to rotate and forming eccentric vibration. During non-freezing weather, rainwater from rainy days drains from the leak holes of the leak cone, and there is no water accumulation inside the leak cone. Under the action of the reset mechanism, the connecting rod is in the upper position. At this time, the clearance between the first and second engagement parts of the permanent magnet clutch is large, and no engagement occurs. The eccentric component disengages from the wind turbine and does not rotate, so the overhead line does not vibrate.

[0009] Furthermore, the reset mechanism is a spring. The spring has a restoring force after being subjected to force, and can drive the connecting rod to reset after the external force is released. Therefore, the permanent magnet clutch does not engage in non-freezing weather.

[0010] Furthermore, it also includes a guiding mechanism. The housing is provided with a guide groove, and the connecting rod is provided with a guide portion, which is inserted into the guide groove. The insertion of the guide portion into the guide groove guides the up-and-down movement of the connecting rod and the leakage cone, restricting the connecting rod to slide only up and down and preventing deflection. This facilitates the engagement and disengagement of the first and second engagement portions of the permanent magnet clutch.

[0011] Furthermore, there are multiple guide grooves, located at the upper and lower parts of the housing, respectively, and the guide part corresponds to each guide groove. The arrangement of multiple guide grooves and guide parts allows for guiding and limiting from different positions on the housing, thereby ensuring the vertical up-and-down movement of the connecting rod.

[0012] Furthermore, it also includes a first antifreeze cover, which is installed at the bottom of the housing and above the leaking cone, with the first rotating shaft passing through the first antifreeze cover. The first antifreeze cover has a conical structure, and its downward-facing installation prevents rainwater from entering the first rotating shaft or the space between the first rotating shaft and the leaking cone, thus preventing condensation.

[0013] Furthermore, the wind turbine includes a second shaft, a hub, and at least three blades. The hub is fixedly connected to the second shaft, and the blades are connected to the hub. Multiple blades are evenly distributed around the second shaft as the center. The second shaft is connected to the housing via a second bearing, and the top of the second shaft is also connected to a second suction part. When wind blows across the blades, the resistance experienced on both sides of the blades differs, i.e., the resistance difference generates a rotational torque, driving the hub to rotate the second shaft, thus converting wind energy into mechanical energy.

[0014] Furthermore, the blades are hemispherical. When wind blows over the hemispherical blades, the concave and convex surfaces experience different resistances, forming a torque around the central axis. This torque drives the hub to rotate the second shaft, converting wind energy into mechanical energy. This wind turbine is not limited by wind direction; on the plane of rotation, wind from any direction drives the wind turbine to rotate towards the convex surface.

[0015] Furthermore, it also includes a second antifreeze cover, which is installed at the bottom of the housing and above the blades. The second rotating shaft passes through the second antifreeze cover, and the second bearing is installed inside the second antifreeze cover. The second antifreeze cover has a conical structure, and its downward-facing installation prevents rainwater from entering the second rotating shaft or the space between the second rotating shaft and the hub, thus preventing condensation.

[0016] Furthermore, the pendulum component is a pendulum. The pendulum is an eccentric element, and it is horizontally positioned with the axis of the second rotating shaft as its center. The second rotating shaft drives the pendulum to rotate. Since there are no other components in the symmetrical position to the pendulum, the center of mass is biased towards the pendulum, and an eccentric force is generated during rotation, resulting in eccentric vibration.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) No manual intervention required: It starts automatically after freezing and requires no manual monitoring; (2) Natural wind power source: No power source is required, which solves the problem of difficulty in obtaining power from high-voltage lines; (3) No power outage required: The power line does not need to be interrupted when this equipment is in operation, and the power transmission is not affected; (4) Good economic efficiency: It is a purely mechanical device with a simple structure, no expensive parts, and low cost; it is easy to construct. The overall cost is low and the economic efficiency is good. Attached Figure Description

[0026] Example 1 like Figures 1 to 4 The image shows a first embodiment of an automatic de-icing device for overhead power lines according to the present invention, comprising: Box 1 is used to install various components, and fasteners for hanging are provided on the outside of box 1; Wind power rotator 2, which uses wind energy to drive its rotation, is installed outside the housing 1 and located below the housing 1. The end of the wind power rotator 2 is inserted into the housing 1. The swaying component 3 is used for vibration de-icing and is installed inside the housing 1; The suction mechanism 4 is partially installed inside the housing 1 and partially installed outside the housing 1, and can move downward under the action of external gravity; The reset mechanism 5 is connected to the suction mechanism 4 and is used for the upward reset of the suction mechanism 4; The oscillating component 3 can be connected to the wind-powered rotator 2 through the suction mechanism 4, and under the action of wind energy, it drives the box 1 to vibrate.

[0027] This invention uses fasteners on the outside of the housing 1 to attach it to the overhead power line. The wind turbine 2 can rotate under the action of wind, providing a power source for the entire system. During freezing weather, rainwater freezes and accumulates on the part of the suction mechanism 4 located outside the housing 1. Under the action of gravity, the suction mechanism 4 will move downward, thereby connecting the swaying member 3 with the wind turbine 2. The wind turbine 2 rotates under the action of wind, driving the swaying member 3 to rotate. During the rotation of the swaying member 3, the swaying will cause the housing 1 to vibrate eccentrically, which in turn will cause the overhead power line to vibrate, causing the ice / ice water mixture on the overhead power line to peel off from the line, achieving the de-icing effect. During non-freezing weather, rainwater will not accumulate on the suction mechanism 4. Under the action of the reset mechanism 5, the suction mechanism 4 will not engage, the swaying member 3 will disengage from the wind turbine 2 and will not rotate, and the overhead power line will not vibrate. This invention requires no manual intervention: it automatically starts after icing without manual monitoring, achieving automatic de-icing of high-voltage overhead lines; it utilizes natural wind power, eliminating the need for an additional power source and solving problems such as the difficulty of obtaining power for high-voltage lines; the overhead lines do not require power outages during the de-icing process, thus not affecting power transmission; moreover, this invention is economical, being a purely mechanical device with a simple structure, no expensive parts, and low cost; it is easy to construct, achieving low-cost and high-efficiency de-icing of overhead lines.

[0028] In one embodiment of the present invention, the engaging mechanism 4 includes a connecting rod 41, a permanent magnet clutch 42, a swivel cone 43, a first rotating shaft 44, a first bearing 45, and a second bearing 46. The connecting rod 41, the permanent magnet clutch 42, and the first bearing 45 are all installed inside the housing 1. The deflector 3 is located in the middle of the connecting rod 41 and is connected to the connecting rod 41 through the first bearing 45. There are two swivel cones 43 located outside the housing 1, and the two swivel cones 43 are symmetrically arranged with the first bearing 45 as the center. The number of reset mechanisms 5 and the number of first rotating shafts 44 are also specified. The number of each component is equal to the number of the leaking cone 43. One leaking cone 43, one first rotating shaft 44, and one reset mechanism 5 correspond to each other. The leaking cone 43 is connected to the connecting rod 41 through the first rotating shaft 44. The reset mechanism 5 is sleeved outside the first rotating shaft 44 and its end abuts against the housing 1. The permanent magnet clutch 42 includes a first engaging part 421 and a second engaging part 422. The first engaging part 421 is connected to the deflector 3, and the second engaging part 422 is connected to the wind turbine 2. The wind turbine 2 is connected to the housing 1 through the second bearing 46.

[0029] Link 41 connects the leak cone 43 and the deflector 3. During freezing weather, the leak hole of the leak cone 43 is blocked by ice, and rainwater accumulates inside the leak cone 43, forming a weight. Under the action of gravity, the overcoming reset mechanism 5 drives the link 41 to sink. The first engagement part 421 of the permanent magnet clutch 42 installed on the link 41 sinks accordingly. When the gap of the permanent magnet clutch 42 reaches a certain distance, it engages with the second engagement part 422 of the permanent magnet clutch 42 installed on the wind turbine 2, and the wind turbine... 2 is connected to the eccentric component 3, which in turn drives the eccentric component 3 to rotate, forming eccentric vibration; in non-freezing weather, rainwater from rainy days is discharged from the leakage hole of the leakage cone 43, and there is no water accumulation in the leakage cone 43. Under the action of the reset mechanism 5, the connecting rod 41 is in the upper position. At this time, the gap between the first engaging part 421 and the second engaging part 422 of the permanent magnet clutch 42 is large, and no engaging occurs. The eccentric component 3 is disengaged from the wind energy rotator 2 and does not rotate, so the overhead line does not vibrate.

[0030] In one embodiment of the present invention, the reset mechanism 5 is a spring. The spring has a restoring force after being subjected to force, and can drive the connecting rod 41 to reset after the external force is released. Therefore, the permanent magnet clutch 42 does not engage in non-freezing weather.

[0031] In one embodiment of the present invention, a guiding mechanism is also included. The housing 1 is provided with a guide groove 11, and the connecting rod 41 is provided with a guide portion 411, which is inserted into the guide groove 11. The insertion of the guide portion 411 into the guide groove 11 guides the up-and-down movement of the connecting rod 41 and the swivel cone 43, restricting the connecting rod 41 to slide only up and down without deflection, which is beneficial to the engagement and disengagement of the first engagement portion 421 and the second engagement portion 422 of the permanent magnet clutch 42.

[0032] In one embodiment of the present invention, a first antifreeze cover 61 is also included. The first antifreeze cover 61 is installed at the bottom of the housing 1 and above the leakage cone 43. The first rotating shaft 44 passes through the first antifreeze cover 61. The first antifreeze cover 61 has a conical structure, and the cone opening is installed downward to prevent rainwater from entering the first rotating shaft 44 or the space between the first rotating shaft 44 and the leakage cone 43, which would cause condensation.

[0033] Because rainwater seeps back during the non-freezing period, and the ice layer itself has a certain strength during the freezing period, the leakage cone 43 itself does not need to bear a large load. It uses lightweight, weather-resistant materials, such as thin aluminum single panels, HDPE, PC endurance boards, etc., which are very light in weight but can hold a large amount of ice water. The weight ratio before and after freezing is very large.

[0034] For example, a 1mm aluminum single-layer cone with a diameter of 40cm and a height of 40cm has a mass ratio of approximately 1:23 before and after being filled with water. The calculation is as follows: 1. Calculate the mass of the empty aluminum cone (before filling with water). Given: Base diameter D = 40cm, radius R = 20cm, height h = 40cm, aluminum plate thickness t = 1mm = 0.1cm. Density of aluminum g / cm3, Calculate the busbar length: cm, Calculate the lateral surface area: cm2, Calculate the volume of the aluminum plate: cm3 Calculate the mass of the empty cone: g.

[0035] 2. Theoretical calculation of the mass of the container filled with water Theoretical volume: (Approximately 16.7 liters) Theoretical water quality: =16755.2g, Theoretical total mass: 758.6 + 16755.2 = 17513.8 g.

[0036] 3. Theoretical mass ratio = 758.6:17513.8 ≈ 1:23.1 If the funnel cone 43 is made larger, the mass ratio will be greater. If the diameter is large enough to not affect the rainwater entering the interior, and it is made into a cylindrical funnel (for containers of the same mass, a cylindrical container has a larger capacity than a conical container), the mass ratio will be even greater.

[0037] Therefore, the compression stroke of the reset mechanism 5, i.e., the spring, will be very large before and after icing. The gravity can be calculated based on the weight of the funnel cone 43, the pendulum, and the connecting rod 41, and then a spring of appropriate strength can be selected in combination with the engagement gap of the permanent magnet clutch 42, so that the permanent magnet clutch 42 is not engaged when it is not icing, and is engaged when it is icing.

[0038] In one embodiment of the present invention, the wind turbine 2 includes a second shaft 21, a hub 22, and at least three blades 23. The hub 22 is fixedly connected to the second shaft 21, and the blades 23 are connected to the hub 22. The multiple blades 23 are evenly distributed around the second shaft 21 as the center. The second shaft 21 is connected to the housing 1 through a second bearing 46, and the top of the second shaft 21 is also connected to a second suction part 422. When wind blows over the blades 23, the resistance on both sides of the blades 23 is different, i.e., the resistance difference generates a rotational torque, which drives the hub 22 to rotate the second shaft 21, converting wind energy into mechanical energy.

[0039] In one embodiment of the present invention, the blade 23 is hemispherical. When wind blows over the hemispherical blade 23, the resistance experienced by the concave and convex surfaces is different, forming a torque around the central axis, which drives the hub 22 to rotate the second shaft 21, converting wind energy into mechanical energy. This wind-powered rotator 2 is not limited by wind direction; on the plane of rotation, wind blowing from any direction drives the wind-powered rotator 2 to rotate towards the convex surface.

[0040] In one embodiment of the present invention, a second antifreeze cover 62 is also included. The second antifreeze cover 62 is installed at the bottom of the housing 1 and above the blade 23. The second rotating shaft 21 passes through the second antifreeze cover 62, and the second bearing 46 is installed inside the second antifreeze cover 62. The second antifreeze cover 62 has a conical structure, and its downward-facing installation prevents rainwater from entering the second rotating shaft 21 or causing condensation between the second rotating shaft 21 and the hub 22. The second antifreeze cover 62 has a thin-walled structure, and a bushing is provided at the connection between the second antifreeze cover 62 and the housing 1. Two second bearings 46 are provided, both installed inside the bushing. The second rotating shaft 21 is installed on the inner ring of the second bearing 46 and can rotate concentrically within the bushing of the second antifreeze cover 62. When rainwater / ice water mixture falls, it lands on the conical outer surface of the second antifreeze cover 62 and cannot enter the second bearing 46, preventing the wind turbine rotator 2 from freezing and jamming.

[0041] In one embodiment of the present invention, the pendulum component 3 is a pendulum. The pendulum is an eccentric element, and the pendulum is horizontally arranged with the axis of the second rotating shaft 21 as the center. The second rotating shaft 21 drives the pendulum to rotate. Since there are no other elements in the symmetrical position to the pendulum, the center of mass is biased towards the pendulum. When rotating, an eccentric force is generated, resulting in eccentric vibration.

[0042] Example 2 The following is a second embodiment of an automatic de-icing device for overhead lines according to the present invention. This embodiment is similar to embodiment 1, except that there are multiple guide grooves 11, which are located at the upper and lower parts of the housing 1 respectively, and the guide part 411 corresponds to the guide groove 11 one by one.

[0043] The arrangement of multiple guide grooves 11 and guide parts 411 allows for guidance and limiting from different positions on the housing 1, thereby ensuring the vertical up-and-down movement of the connecting rod 41.

[0044] Example 3 The following is a third embodiment of an automatic de-icing device for overhead lines according to the present invention. This embodiment is similar to embodiment 1, except that there are multiple leakage cones 43, which are evenly distributed around the first bearing 45.

[0045] Multiple leakage cones 43 are evenly distributed around the first bearing 45, so that the connecting rod 41 is subjected to uniform force. In freezing weather, the leakage holes of the leakage cones 43 are blocked by ice, and rainwater is stored inside the leakage cones 43, forming a weight that drives the connecting rod 41 to move downward, so that the first engagement part 421 and the second engagement part 422 of the permanent magnet clutch 42 can engage with each other. Under uniform force, the working life of the connecting rod 41 can be effectively extended. Moreover, the accurate engagement of the first engagement part 421 and the second engagement part 422 is beneficial.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
