Description

Technical Field

[0001] This utility model relates to the field of anti-icing and de-icing technology for overhead power transmission lines or railway contact networks, and in particular to a mechanical transmission device for de-icing overhead power transmission lines. Background Technology

[0002] Ice accumulation on overhead power transmission lines has always been one of the most serious natural disasters in the power system at home and abroad. Mechanical de-icing is a conventional method for preventing and removing ice on overhead power transmission lines. Utility model [1] "Mechanical Vibration De-icing Device" (CN201417921Y), utility model [2] "High-rise Cable Air Explosion Vibration De-icing Device" (CN201549858U), and utility model [3] "An Overhead Ground Wire Mechanical Vibration De-icing Device" (CN201247941Y) all work on the principle of driving the conductors or ground wires of overhead power transmission lines to vibrate through energy units and mechanical mechanisms to carry out anti-icing and de-icing operations. In this regard, the state has also issued corresponding industry standards, "Technical Guidelines for the Use of Mechanical Vibration De-icing Devices for Overhead Power Transmission Line Conductors and Ground Wires" (DL / T 1922-2018), which makes relevant specifications for de-icing operations and de-icing processes. However, the energy source of the power units of the above-mentioned utility models uses military pyrotechnics such as blank ammunition, which greatly limits the application scenarios, application scope and application conditions. Moreover, the de-icing process requires not only power outages but also extensive manual intervention, resulting in low operational efficiency. To address this, utility models such as [4] "Anti-icing and de-icing device, spacer, system and anti-dancing system based on center of gravity change" (CN115642555A), [5] "Anti-icing and de-icing device, spacer, post insulator and system for overhead transmission lines" (CN115483658B), and [6] "Anti-icing and de-icing device for split conductors of overhead transmission lines, spacer and system for sub-conductors" (CN115632367A) have proposed a mechanical vibration de-icing device for overhead transmission lines that uses a motor as the power unit and a spring as the energy storage and release device. This not only avoids the limitations of using pyrotechnics but also requires minimal manual intervention, achieving de-icing without power outages and with less manual involvement, thus significantly improving the efficiency of anti-icing and de-icing. Utility Model Content

[0003] Mechanical vibration de-icing devices for overhead transmission lines are installed on the conductors or ground wires of the overhead transmission lines. This installation location not only makes the device difficult to install but also requires a high degree of lightweight design, demanding high mass energy density and volume energy density—that is, generating a strong vibration effect with a small mass and volume. On the other hand, the conductors and ground wires of overhead transmission lines cannot directly provide energy, making it very difficult to obtain the energy to power the device's vibration. Generally, energy is collected from solar or wind power, or from the magnetic field energy around the current-carrying conductors. This requires high transmission efficiency to generate sufficient vibration with relatively limited energy to meet the de-icing requirements of overhead transmission lines.

[0004] The anti-icing and de-icing devices proposed in utility models [4~6] all include transmission and energy storage components such as motors, reduction mechanisms, clutch mechanisms, and springs. However, how to reasonably connect these components to better suit the actual operating environment and improve de-icing efficiency; how to optimize the transmission relationship between these components to improve the overall reliability of the device; and how to protect the weak links in the entire transmission system to improve the overall reliability of the system. In the structural design of the transmission system in this application, the following factors need to be considered: First, the overall transmission system of the device needs to simultaneously meet the requirements of lightweight design and high transmission efficiency. Second, the mechanical vibration de-icing device for overhead transmission lines itself achieves anti-icing and de-icing of overhead transmission lines through vibration. However, as a vibration source, some components of the device itself have insufficient tolerance to vibration, such as the rotor of the motor, the brushes of the motor, and related circuit components; and the reduction gears and reduction components of planetary or cycloidal reduction gears. Because of the existence of these relatively precise and delicate components, when designing the transmission system of the device, sufficient vibration damping protection should be provided for these components. Thirdly, in addition to the above, the installation process between different components needs to be considered. Easy installation, high standardization of parts, and a relatively small number of types are beneficial for cost reduction and overall structural lightweighting. Fourthly, the various transmission components have simple processing techniques, are easy to manufacture, and have low costs. Considering all these factors, how to design and optimize such a transmission system, how to rationally install, fix, and connect these components to better suit the actual operating environment, improve de-icing efficiency, and enhance the overall reliability of the device, requires a comprehensive consideration of the load spectrum, lightweighting, transmission efficiency, and vibration damping protection of key components. Balancing trade-offs between different technical indicators such as overall lightweighting and transmission efficiency are all urgent problems that need to be solved.

[0005] In view of the above-mentioned constraints and the various factors that need to be comprehensively compromised, this utility model proposes a power unit and a matching mechanical transmission system applicable to utility models [1~6]. It has strong practicality and reliability, and the overall device is compact, lightweight, and has high transmission efficiency, thus better meeting the needs of anti-icing and de-icing in actual operation. This application focuses on the following optimization measures.

[0006] 1. By placing a multi-stage reduction mechanism with a large reduction ratio before the worm gear reduction mechanism, the anti-reverse characteristics of the worm wheel and worm are used to protect the relatively easily damaged multi-stage reduction mechanism in front. This not only improves the overall reliability of the transmission system, but also facilitates the use of multi-stage reduction mechanisms with different speed ratios, which is conducive to improving the standardization and serialization of products, and has good compatibility and reliability.

[0007] 2. Placing the multi-stage reduction mechanism before the worm gear reduction mechanism allows the multi-stage reduction mechanism to use a larger reduction ratio, while the worm gear reduction mechanism in the subsequent stage can use a smaller reduction ratio. This reduces the overall weight of the reduction mechanism and improves the overall energy density and lightweight level of the reduction transmission system.

[0008] 3. The rational use of rigid and flexible (or elastic) transmission connections improves transmission efficiency while ensuring the overall reliability of the device and protecting weaker components with poor vibration resistance. In the transmission system of the entire device, the initial stage has a higher speed, while the subsequent stage has a lower speed. From the initial stage to the subsequent stage, it includes: a motor, a multi-stage reduction mechanism, a worm gear reduction mechanism, incomplete gears, and energy storage and release mechanisms corresponding to moving parts and springs. Generally, rigid connections have higher transmission efficiency, while flexible connections have lower efficiency. However, rigid connections place higher demands on machining accuracy, assembly conditions, and the vibration resistance of related components. Therefore, the quantity and reasonable installation position of flexible couplings, rigid couplings, or flexible couplings (rigid couplings or flexible couplings are defined and classified according to GB / T 12458-2017 Coupling Classification) are crucial to the overall performance of the device. Installing flexible couplings too far forward will affect the overall transmission efficiency. If the flexible coupling is installed too far back in the stage, its size will be excessive, affecting the energy density of the device. Furthermore, the specific installation location of the flexible coupling needs to be considered to protect weak points in the device with poor vibration resistance. This application, through system design of the transmission system, reduces the number of flexible couplings used and rationally arranges their transmission positions. While meeting overall performance requirements such as transmission efficiency, process requirements, assembly conditions, and vibration resistance, it improves transmission efficiency.

[0009] 4. The motor and multi-stage reduction mechanism are the weakest links in the entire device, exhibiting poor vibration resistance. Improving the motor's vibration resistance and increasing the system's transmission efficiency are inherently contradictory. Improving transmission efficiency requires rigid transmission, while improving vibration resistance precludes rigid connections to prevent vibration from being transmitted to the motor and multi-stage reduction mechanism. In this application, a flexible coupling is added between the output end of the multi-stage reduction mechanism and the input end of the worm gear mechanism, which improves the vibration resistance of the motor and multi-stage reduction mechanism to a certain extent, while simultaneously achieving both lightweight design and transmission efficiency.

[0010] 5. By utilizing the coaxial rigid connection between the worm gear and the incomplete gear, not only is the overall transmission efficiency improved, but the overall device is also more compact, lubrication is more convenient, and the overall reliability is greatly improved.

[0011] 6. To address the issue of springs easily bending unnecessarily along the axial direction under stress, this application fully utilizes existing structural components to constrain the deformation direction of the spring and avoid unnecessary energy loss. The outer slide cylinder is formed using the spring shell of the spring structural components, and the inner slide rod is formed using a rack, thus constraining the deformation direction of the spring without adding any additional parts.

[0012] Based on the above constraints and the various factors that need to be comprehensively compromised, this utility model proposes a mechanical transmission device for de-icing overhead transmission lines, comprising: a housing, a motor, a multi-stage reduction mechanism, a worm gear, a worm, an incomplete gear, and an actuator.

Detailed Implementation

[0046] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0047] like Figure 1 As shown, this utility model embodiment provides a mechanical transmission device for de-icing overhead power transmission lines. The device is used on overhead power transmission lines or railway contact wires and includes: a housing 1, a motor 2, a multi-stage reduction mechanism 3, a worm gear 4, a worm 5, an incomplete gear 6, and an actuator.

[0048] The housing 1 is the foundation of the de-icing mechanical transmission device for overhead transmission lines. It is used to connect with overhead transmission lines and railway contact networks, or to combine with conductor spacers, phase-to-phase spacers, and phase-to-ground spacers. It also houses the motor 2, multi-stage reduction mechanism 3, worm gear 4, worm 5, incomplete gear 6, and actuator. Figure 1 In the case 1, the motor 2, the multi-stage reduction mechanism 3, the worm gear 4, the worm 5, the incomplete gear 6, and the actuator are housed inside the housing 1.

[0049] The specific embodiments of this utility model provide an overhead transmission line de-icing mechanical transmission device, such as... Figure 2 As shown. Figure 2In this configuration, motor 2 is mounted on housing 1. The output end of motor 2 is connected to the input end of multi-stage reduction mechanism 3, and the output end of multi-stage reduction mechanism 3 is connected to worm gear 5. Worm wheel 4 meshes with worm gear 5 for transmission, and worm wheel 4 is also connected to incomplete gear 6 for transmission. The types of transmission connections include coaxial transmission, gear transmission, chain transmission, belt transmission, and coupling transmission. Figure 2 As shown, the transmission connection between the output end of the multi-stage reduction mechanism 3 and the worm 5 is a coupling drive, and the transmission connection between the worm wheel 4 and the incomplete gear 6 is a coaxial drive.

[0050] In this invention, the motor 2 and the multi-stage reduction mechanism 3 are high-speed, low-torque transmission links, employing a multi-stage planetary gear reduction mechanism or a multi-stage cycloidal reduction mechanism. The gear reduction part is a low-speed, high-torque transmission link, employing a worm gear and worm 5 worm gear reduction mechanism, which is beneficial for improving the power density and energy density of the overall device. For the different spaces occupied by the high-speed, low-torque transmission link and the low-speed, high-torque transmission link, lubricating oil and grease are used respectively to solve the lubrication problem when the speed difference of the multi-stage reduction is too large.

[0051] The multi-stage reduction mechanism 3 can be formed by connecting multiple reduction mechanisms of the same type in series, or by connecting multiple reduction mechanisms of different types in series.

[0052] In this invention, the worm gear 4 and the incomplete gear 6 are coaxial, which reduces the number of parts in the device, improves the reliability of the device, and enhances the vibration resistance of the device.

[0053] The tooth circumference of the incomplete gear 6 includes a toothed portion 62 and a smooth portion 61. The toothed portion 62 of the incomplete gear 6 is a segment of teeth of a predetermined length arranged along the circumference of the incomplete gear 6. The portion of the incomplete gear 6 without teeth along its circumference is the smooth portion 61, and the sum of the lengths of the toothed portion 62 and the smooth portion 61 is equal to the circumference of the incomplete gear 6.

[0054] In some examples, the device also includes a motor control module electrically connected to the motor 2 for controlling the motor 2's movements, including forward rotation, reverse rotation, stopping, and speed adjustment. A motor control module interface is also provided on the housing 1 to electrically connect the motor control module to the motor 2 for controlling the motor 2's movements.

[0055] In this embodiment of the invention, the output end of the motor 2 is connected to the input end of the multi-stage reduction mechanism 3, and the output end of the multi-stage reduction mechanism 3 is connected to the worm 5 via a coupling. This allows the worm 5 to rotate under the drive of the output end of the motor 2, along with the multi-stage reduction mechanism 3. The worm wheel 4 meshes with the worm 5, so its teeth mesh with the teeth of the worm 5. When the worm 5 rotates with the multi-stage reduction mechanism 3 and the motor 2, the worm wheel 4 rotates simultaneously. The incomplete gear 6 is coaxially connected to the worm wheel 4, and both are fixedly mounted on the same shaft. When the worm wheel 4 rotates due to the drive of the worm 5, it drives the coaxial shaft of the worm wheel 4 and the incomplete gear 6 to rotate, and the incomplete gear 6 also rotates with the shaft. The output end of the multi-stage reduction mechanism 3 is coaxially connected to the worm 5 via a flexible coupling or an elastic coupling.

[0056] In the embodiments of this utility model, the combination of worm gear 4 and worm 5 has a reverse-blocking function, which is used to block the impact and prevent the front-stage planetary gear in the multi-stage reduction mechanism 3 connected to the worm 5 from reversing.

[0057] The incomplete gear 6 is engaged with the actuator in a transmission. The tooth circumference of the incomplete gear 6 includes a smooth part 61 and a toothed part 62. When the toothed part 62 is engaged with the actuator, the incomplete gear 6 drives the actuator to move and accumulates elastic potential energy. When the smooth part 61 is engaged with the actuator, the incomplete gear 6 is disengaged from the actuator, and the actuator moves under the action of elastic potential energy and releases energy.

[0058] The actuator involved in this utility model includes a first structure and a second structure; wherein, the actuator configured with the first structure is as follows: Figure 3 .

[0059] like Figure 3 As shown, the actuator includes a rack 71 and a first spring 72. The rack 71 is mounted on the housing 1 and is telescopically engaged with the housing 1. One end of the first spring 72 is connected to the rack 71, and the other end is connected to the housing 1.

[0060] When the execution mechanism is set up in the following way Figure 3In the first structure shown, rack 71 is engaged with incomplete gear 6. When incomplete gear 6 and rack 71 are engaged, incomplete gear 6 transmits force, torque, or motion to rack 71; when incomplete gear 6 is disengaged from rack 71, the transmission of force, torque, or motion from incomplete gear 6 to rack 71 is cut off. As mentioned earlier, incomplete gear 6 is coaxially connected to worm gear 4. When it rotates with worm gear 4, the teeth of rack 71 mesh with the tooth portion 62 of incomplete gear 6. When incomplete gear 6 rotates, its tooth portion 62 drives rack 71 to displace relative to housing 1. Rack 71 moves towards first spring 72 and compresses first spring 72, causing first spring 72 to deform and accumulate elastic potential energy.

[0061] Specifically, such as Figure 3 As shown, a tooth of a preset length is provided at a designated position on the surface of the rack 71, and the tooth of the rack 71 meshes with the tooth portion 62 of the incomplete gear 6.

[0062] like Figure 3 As shown, one end of the first spring 72 is fixedly connected to the base 77, and the other end is fixedly connected to the end of the rack 71. Specifically, an end cap 79 is provided at the end of the rack 71, and the diameter of the end cap 79 is greater than or equal to the diameter of the spring.

[0063] When the incomplete gear 6 and rack 71 are engaged, the motor 2 can drive the rack 71 to produce a displacement relative to the housing 1. This displacement is a linear motion along the extension direction of the rack 71.

[0064] By controlling the rotation direction and rotation time of motor 2, power is transmitted to incomplete gear 6 through multi-stage reduction mechanism 3, worm gear 4, and worm 5. The toothed portion 62 of incomplete gear 6 drives rack 71 to move. The end cap 79 at the end of rack 71 moves with rack 71, and the first spring 72 connected to the end of rack 71 deforms as rack 71 moves. In this embodiment of the invention, by controlling the rotation direction of motor 2, the rotation direction of incomplete gear 6 can be controlled, and further, the movement direction of rack 71 can be controlled. Specifically, when... Figure 3 When the incomplete gear 6 rotates clockwise, it can drive the rack 71 to move away from the first spring 72, causing the first spring 72 to begin to stretch and deform, and also to accumulate elastic potential energy; while when Figure 3 When the incomplete gear 6 rotates counterclockwise, it can drive the rack 71 to move toward the first spring 72, causing the first spring 72 to begin to compress, deform, and accumulate elastic potential energy.

[0065] When rack 71 engages with the smooth portion 61 of incomplete gear 6, rack 71 disengages from incomplete gear 6, and the first spring 72 releases the stored elastic potential energy, driving rack 71 to reset.

[0066] Figure 4 The diagram shows the structure of the incomplete gear 6. The incomplete gear 6 rotates continuously. Since the circumference of the incomplete gear 6 also includes a smooth portion 61, when the toothed portion 62 rotates to the point where it separates from the teeth of the rack 71, the incomplete gear 6 and the rack 71 separate. At this moment, the deformed first spring 72 begins to recover and instantaneously releases its elastic potential energy, generating an instantaneous thrust on the base 77. When the base 77 is connected to the overhead power transmission line or railway contact network, the thrust of the elastic potential energy on the base 77 is transmitted to the overhead power transmission line or railway contact network, causing vibration and achieving the effect of anti-icing or de-icing.

[0067] In an embodiment of this utility model, to increase the extension and retraction stroke of the first spring 72, a first gear 101 and a third gear 106 are added to the de-icing mechanical transmission device for overhead power transmission lines. For example... Figure 5 As shown, the worm gear 4 and the incomplete gear 6 are connected by a coaxial transmission, and the third gear 106 and the first gear 101 are connected by a transmission. Specifically, it can be a coaxial transmission. The teeth of the incomplete gear 6 and the third gear 106 are set to mesh with each other to enable the transmission between the two. The teeth of the first gear 101 and the rack 71 are set to mesh with each other to enable the transmission between the two.

[0068] By setting the first gear 101 and the third gear 106, an additional stage of transmission is added. By increasing the diameter of the incomplete gear 6, the displacement of the rack 71 can be increased during the process from the toothed part 62 engaging with the third gear 106 to the smooth part 61 engaging with the third gear 106, thereby increasing the extension and retraction stroke of the first spring 72.

[0069] At this time, by controlling the speed and running time of the motor 2, the motor 2 drives the multi-stage reduction mechanism 3, the worm 5 and the worm wheel 4 to rotate. The worm wheel 4 drives the incomplete gear 6 to rotate. The third gear 106, because it meshes with the teeth of the incomplete gear 6, also rotates with the incomplete gear 6, further driving the first gear 101 to rotate.

[0070] At this time, the toothed portion 62 of the incomplete gear 6 meshes with the teeth of the third gear 106, driving the third gear 106 and the first gear 101 to rotate. The teeth of the first gear 101 mesh with the teeth of the rack 71, and the teeth of the first gear 101 and the rack 71 cooperate, causing the rack 71 to undergo relative displacement with the housing 1, thereby causing the first spring 72 to deform and accumulate elastic potential energy.

[0071] The incomplete gear 6 rotates continuously. Since the circumference of the incomplete gear 6 also includes a smooth portion 61, when the toothed portion 62 rotates to the point where it separates from the teeth of the third gear 106, the incomplete gear 6 and the third gear 106 separate. At this point, neither the first gear 101 nor the third gear 106 is under force. The first gear 101 no longer exerts force on the rack 71. The deformed first spring 72 stops accumulating potential energy, begins to recover, and instantaneously releases its elastic potential energy, generating an instantaneous force on the base 77. When the base 77 is connected to the overhead power transmission line or railway contact network, the force exerted by the elastic potential energy on the base 77 causes the overhead power transmission line or railway contact network to vibrate, achieving the effect of anti-icing or de-icing.

[0072] In this embodiment, as Figure 1 In this configuration, when the de-icing mechanical transmission device for overhead transmission lines is installed between conductors of the same phase of the overhead transmission line, one end of the first spring 72 is connected to the first clamp 11, which is used to connect one conductor of the same phase of the overhead transmission line; the other end of the first spring 72 is connected to one end of the rack 71; the other end of the rack 71 is connected to the second clamp 12, which is used to connect another conductor of the same phase of another overhead transmission line. Alternatively, the de-icing mechanical transmission device can also be installed between conductors of different phases of the overhead transmission line, or between conductors and ground wires of the overhead transmission line. That is, the first clamp 11 is used to connect conductors or ground wires of the overhead transmission line, and the second clamp 12 is used to connect conductors or ground wires of another overhead transmission line.

[0073] In other embodiments of this utility model, when the de-icing mechanical transmission device for overhead transmission lines is installed between conductors of different phases of the overhead transmission line, or between the conductor and the ground wire of the overhead transmission line, one end of the first spring 72 is connected to the first clamp 11 through the first insulating component, and / or the other end of the rack 71 is connected to the second clamp 12 through the second insulating component. In this embodiment, both the first insulating component and the second insulating component can be insulators.

[0074] In some embodiments of this utility model, the actuator included in the overhead transmission line de-icing mechanical transmission device of this utility model can also be configured in a second structure manner, and when the actuator is configured in a second structure manner, its structure is as follows: Figure 6 and Figure 7 As shown. The following is... Figure 7 Taking this example as an illustration, the actuator of this embodiment includes: a winding shaft 73, a flexible connecting component 74, and a second spring 75. The winding shaft 73 is disposed on the housing 1 and connected to one end of the flexible connecting component 74. The other end of the flexible connecting component 74 is connected to the heavy impact block 76.

[0075] Specifically, this embodiment also includes a third gear 106, which is disposed on the housing 1. Specifically, the third gear 106 is sleeved on the second gear shaft 103, and the second gear shaft 103 is coaxially connected to the winding shaft 73, so that the third gear 106 and the winding shaft 73 are coaxially connected. In this embodiment, the winding shaft 73 and the second gear shaft 103 can be different parts of the same integrally formed shaft, or they can be independent shafts coaxially connected. They are connected by a coupling, and the rotation of the second gear shaft 103 drives the rotation of the winding shaft 73.

[0076] In this embodiment, a spring bracket 78 is provided on the housing 1, and one end of the second spring 75 is fixed to the spring bracket 78 so that the end of the second spring 75 is connected to the housing 1, and the other end is connected to the heavy impact block 76. The flexible connecting component 74 is a flexible rope, one end of which is fixed to the winding shaft 73, and the other end is connected to the heavy impact block 76.

[0077] The impact block 76 involved in this invention is an object with a certain mass. It can be made of a high-density solid material with a certain degree of hardness, elasticity, or toughness, which helps to improve the vibration effect generated by the device. The mass of the weight and the parameters of the spring are selected comprehensively according to the vibration effect required by the device.

[0078] The winding shaft 73 is coaxially driven with the second gear shaft 103. The winding shaft 73 is fixedly connected to one end of the flexible connecting member 74, and the flexible connecting member 74 is wound on the winding shaft 73. The flexible connecting member 74 pulls the heavy impact block 76 to displace relative to the housing 1, thereby causing the second spring 75 to deform and accumulate elastic potential energy.

[0079] The incomplete gear 6 engages with the second gear 102. Specifically, the teeth of the second gear 102 mesh with the teeth 62 of the incomplete gear 6. The rotation of the incomplete gear 6 drives the rotation of the second gear 102, which in turn drives the rotation of the second gear shaft 103, thereby driving the winding shaft 73 to rotate. The flexible rope fixed to the shaft of the winding shaft 73 begins to wind on the winding shaft 73. By controlling the rotation direction of the motor 2, the flexible rope pulls the heavy impact block 76 towards the winding shaft 73 during the winding process. The second spring 75 is disposed between the heavy impact block 76 and the spring support 78. The second spring 75 moves with the heavy impact block 76 towards the direction of the spring support 78. The spring support 78 is fixedly disposed on the housing 1 and limits the deformation of the spring. The tension of the flexible rope causes the second spring 75 to begin to compress and deform between the heavy impact block 76 and the spring support 78, accumulating elastic potential energy.

[0080] When the second gear 102 engages with the smooth portion 61 of the incomplete gear 6, the second gear 102 disengages from the incomplete gear 6, the second gear 102 stops driving the second gear shaft 103, the second gear shaft 103 and the winding shaft 73 are no longer under force and rotate, the tension of the flexible rope on the heavy impact block 76 disappears, the second spring 75 stops compressing, the elastic potential energy accumulated due to compression deformation is released, thereby driving the heavy impact block 76 to reset.

[0081] At this moment, the compressed second spring 75 begins to recover and instantly releases the stored elastic potential energy. The second spring 75 exerts an instantaneous force on the heavy impact block 76, pushing the heavy impact block 76 away from the spring support 78 and causing it to impact the base 77. This utility model connects the base 77 to the overhead power transmission line or railway contact network. The released elastic potential energy exerts a thrust on the base 77, causing the overhead power transmission line or railway contact network to vibrate, achieving the effect of anti-icing or de-icing.

[0082] like Figure 7 As shown in this embodiment of the invention, a winding wheel 731 is provided on the winding shaft 73. One end of the flexible connecting member 74 is connected to the heavy impact block 76, and the other end is connected to the winding wheel 731 through a spring bracket 78. In one embodiment, a winding wheel 731 is provided at the middle position of the winding shaft 73, and a corresponding flexible connecting member 74 is provided. One end of the flexible connecting member 74 is fixedly connected to the winding wheel 731, and the other end is connected to the center position of the heavy impact block 76. The flexible connecting member 74 passes through the interior of the second spring 75. By providing the winding wheel 731, the winding position of the flexible connecting member 74 on the winding shaft 73 can be restricted.

[0083] In other embodiments of this utility model, such as Figure 8 As shown, there are at least two winding wheels 731, including a first winding wheel 732 and a second winding wheel 733, and at least two flexible connecting parts 74, including a first flexible connecting part 741 and a second flexible connecting part 742. Specifically, the first winding wheel 732 and the second winding wheel 733 are symmetrically arranged at both ends of the winding shaft 73. Two sets of flexible connecting parts 74 are arranged corresponding to the winding wheels, namely the first flexible connecting part 741 and the second flexible connecting part 742. One end of the first flexible connecting part 741 is fixed to the first winding wheel 732, and the other end is connected to the heavy impact block 76; one end of the second flexible connecting part 742 is fixed to the second winding wheel 733, and the other end is connected to the heavy impact block 76. Figure 8 When the actuator shown is applied to the device, the resulting internal structure is as follows: Figure 6 As shown.

[0084] In this embodiment, the impact block 76 is configured as a regular cubic structure. When the first flexible connecting component 741 and the second flexible connecting component 742 are connected to it, the connection positions are symmetrical about the bottom surface of the regular cube with respect to the center position, so that the first flexible connecting component 741 and the second flexible connecting component 742 pull the impact block 76 with the same or nearly the same tension during the winding process. The regular cubic structure can be a cube, cuboid, or cylinder.

[0085] Furthermore, in an alternative embodiment, such as Figure 9 As shown, the flexible connecting component 74 in this utility model can be connected to form a flexible rope. The flexible rope is symmetrically wound around the first winding wheel 732 and the second winding wheel 733. At the same time, through holes are provided on opposite sides of the first winding wheel 732 and the second winding wheel 733, namely the first through hole 7321 and the second through hole 7331. The two ends of the flexible rope are connected to the heavy impact block 76 according to the aforementioned embodiment, and the rope body passes through the first through hole 7321 and the second through hole 7331 respectively. In other words, a first through hole 7321 is provided on the side wall of the first winding wheel 732 facing the second winding wheel 733, and the first through hole 7321 is located near the winding shaft 73; second through holes 7331 are symmetrically provided on the side wall of the second winding wheel 733 facing the first winding wheel 732, and the second through holes 7331 are located near the winding shaft 73; one end of the first flexible connecting member 741 passes through the first through hole 7321, and one end of the second flexible connecting member 742 passes through the second through hole 7331 and is connected to one end of the first flexible connecting member 741. Through this configuration, it can be ensured that the tension of the flexible rope at both ends on the impact block 76 remains balanced during the winding process. The configuration of the first through hole 7321 and the second through hole 7331 is as follows... Figure 10 As shown.

[0086] When the actuator is the second structure, corresponding to the large extension and retraction stroke of the second spring 75, the original structure of the overhead transmission line de-icing mechanical transmission device is improved. Specifically, the diameter of the winding shaft 73 is increased, and the winding depth of the winding wheel 731 is increased. Through the above improvements, more flexible connecting parts 74 can be wound onto the winding wheel 731, thereby enabling the second spring 75 to compress with a larger stroke.

[0087] like Figure 9As shown, to prevent the spring bodies of the first spring 72 or the second spring 75 from bending, an inner slide rod 105 is provided inside the spring body of the first spring 72 or the second spring 75 to limit the deformation direction of the first spring 72 or the second spring 75. Specifically, in this embodiment, an inner slide rod 105 is provided between the spring bracket 78 and the base 77. The second spring 75 is sleeved on the rod body of the inner slide rod 105, and the weight impact block 76 is set in a ring shape. The ring-shaped weight impact block 76 is sleeved on the rod body of the inner slide rod 105, and the inner diameter of the ring of the weight impact block 76 is larger than the diameter of the rod body of the inner slide rod 105. Figure 2 In the embodiment shown, rack 71 is used as an inner slide bar.

[0088] In other embodiments of this utility model, to prevent the spring body of the first spring 72 or the second spring 75 from bending, an outer slide cylinder 104 is provided on the outside of the spring body of the first spring 72 or the second spring 75, and the deformation direction of the first spring 72 or the second spring 75 is restricted by the outer slide cylinder 104. The arrangement of the second spring 75 and the flexible connecting member 74 is the same as... Figure 7 The connection method shown is the same. By setting the outer slide cylinder 104, the deformation mode of the first spring 72 or the second spring 75 can be restricted, preventing the first spring 72 or the second spring 75 from bending and preventing the spring from deforming in directions other than the extension direction of the first spring 72 or the second spring 75. With the outer slide cylinder 104 set in this embodiment, the deformation of the first spring 72 or the second spring 75 can be restricted inside the cylinder body of the outer slide cylinder 104. The structure of the outer slide cylinder 104 is as follows: Figure 1 As shown in the image.

[0089] Figure 1 The multi-stage reduction mechanism 3 and the outer slide cylinder 104 are arranged in parallel, making the overall structure of the device reasonable and relatively compact, further improving the power density and energy density of the device.

[0090] In embodiments of this invention, the frequency of device operation can be set by utilizing the duration of the separation between the incomplete gear 6 and the rack 71 or the second gear 102. The duration of the separation between the incomplete gear 6 and the rack 71 or the second gear 102 is set by controlling the rotation, stop, and speed of the motor 2, or by the curvature of the smooth portion 61 of the incomplete gear 6. By setting the duration of the separation, not only can the reliability of the device be effectively improved, but the frequency of operation of the overhead transmission line de-icing mechanical transmission device can also be easily adjusted, increasing the types of anti-icing and de-icing applications it can handle, or allowing different devices to coordinate their actions according to a set sequence, thereby enhancing the anti-icing and de-icing effect.

[0091] From the initial engagement of the incomplete gear 6 and rack 71 or the second gear 102, to the initial transition from the disengaged state to the engaged state, and then back to the engaged state, the overhead transmission line de-icing mechanical transmission device of this invention completes a process from slow energy accumulation to rapid energy release. Correspondingly, the heavy impact block 76 relative to the housing 1 completes a process from a slow initial position to a final position and then rapidly returns to the initial position. This cyclical repetition generates vibrations of a certain frequency on the overhead transmission line or railway contact network, effectively suppressing or interfering with the icing process and achieving the purpose of anti-icing and de-icing.

[0092] like Figure 2 , Figure 5 As shown, the solution disclosed in this utility model is a mechanical transmission device for de-icing overhead transmission lines. The mechanical transmission device for de-icing overhead transmission lines is fixed on the overhead transmission line by a first clamp 11 and a second clamp 12. The overhead power line de-icing mechanical transmission device installed between the first clamp 11 and the second clamp 12 receives electrical energy from the motor 2 and outputs power or torque. This output power or torque is then transmitted to the rack 71 via a multi-stage reduction mechanism 3, worm gear 5, worm wheel 4, and incomplete gear 6. When the teeth 62 of the incomplete gear 6 engage with the rack 71, the incomplete gear 6 drives the rack 71 to displace relative to the housing 1. During this displacement, the rack 71 causes the first spring 72 to deform and accumulate elastic potential energy. When the incomplete gear 6 rotates to the point where its smooth part 61 engages with the rack 71, the transmission engagement between the incomplete gear 6 and the rack 71 disengages, and the rack 71 no longer displaces relative to the housing 1. The first spring 72 recovers its deformation and releases its elastic potential energy. This released elastic potential energy acts on the rack 71, causing it to undergo variable acceleration. When the rack 71 undergoes variable acceleration and comes into contact with other components, it causes those components to vibrate. Based on this, if... Figure 11 and Figure 12 As shown, this utility model connects the ice-breaking head 81, which directly contacts the overhead transmission line conductor or ground wire for ice breaking, to the housing 1. Specifically, the ice-breaking head 81 is connected to the housing 1; the ice-breaking head 81 abuts against the overhead transmission line conductor or ground wire to be de-iced; when the first spring 72 releases its elastic potential energy, the elastic potential energy drives the rack 71 to move and impact the housing 1, thereby driving the ice-breaking head 81 to impact the overhead transmission line conductor or ground wire to be de-iced for ice removal.

[0093] in Figure 11The bottom opening of the outer sliding cylinder 104 allows the rack 71 to extend to the outside of the cylinder. An ice-breaking head 81 is fixedly installed at the end of the rack 71 extending outside the cylinder. When the mechanical vibration mechanism vibrates, the ice-breaking head 81 directly impacts the overhead transmission line conductor or ground wire, thus removing ice from the overhead transmission line conductor or ground wire. Figure 12 The ice-breaking head 81 is then fixedly installed in conjunction with... Figure 11 At the other end of the rack 71, which is opposite to the other end, the movement direction of the motor is controlled to move the rack 71 into the outer slide cylinder 104, compressing the first spring 72. When the incomplete gear 6 and the rack 71 disengage from the transmission, the first spring 72 releases its elastic potential energy, causing the rack 71 to move away from the outer slide cylinder 104 with variable acceleration, driving the ice-breaking head 81 to directly impact the overhead transmission line conductor or ground wire, thus achieving the de-icing action on the overhead transmission line conductor or ground wire. Simultaneously, a limiting rod 82 is provided on the end face of the ice-breaking head 81 that contacts the overhead transmission line conductor or ground wire to limit the contact between the ice-breaking head 81 and the overhead transmission line conductor or ground wire. Typically, three limiting rods 82 are provided, evenly fixed on the ice-breaking end face of the ice-breaking head 81. The ice-breaking end face of the ice-breaking head 81 can be configured as a flat surface, an arc surface, or other suitable surface structure as needed.

[0094] like Figure 12 When the ice-breaking head 81 is set at the first end 711 of the rack 71, the ice-breaking head 81 is connected to the housing 1 through the rack 71, and the first end 711 of the rack 71 passes through the housing 1 and extends to the outside of the housing 1. like Figure 11 When the ice-breaking head 81 is set at the second end 712 of the rack 71, the ice-breaking head 81 is connected to the housing 1 through the rack 71. The housing 1 is provided with a through hole 321, and the second end 712 of the rack 71 extends to the outside of the housing 1 through the through hole 321.

[0095] like Figure 13 As shown, when the ice-breaking head 81 is set at the second end 712 of the rack 71, the second end 712 of the rack 71 is fixedly connected to one end of the impact rod 83, and the other end of the impact rod 83 is connected to the ice-breaking head 81.

[0096] like Figure 14 As shown, optionally, the housing 1 is connected to the extension sleeve 84; The impact rod 83 includes an impact block 831 and a connecting rod 832. The impact block 831 is disposed in the housing 1. One end of the connecting rod 832 is fixedly connected to the impact block 831, and the other end passes through the extension sleeve 84, extends to the outside and is connected to the ice-breaking head 81. At this time, the ice-breaking head 81 is connected to the housing 1 through the impact rod 83 and the extension sleeve 84. When the first spring 72 releases its elastic potential energy, the elastic potential energy is converted into the kinetic energy of the rack 71, causing the rack 71 to undergo variable acceleration motion and strike the impact block 831. The connecting rod 832 connecting the impact block 831 drives the ice-breaking head 81 to strike the overhead transmission line conductor or ground wire to be de-iced for de-icing.

[0097] The ice-breaking head 81 is used to strike the end face of the overhead transmission line conductor or ground wire to be de-iced, which is equipped with a limiting rod 82.

[0098] Unlike existing technologies, this utility model's overhead transmission line de-icing mechanical transmission device includes a housing, a motor, a multi-stage reduction mechanism, a worm gear, a worm, an incomplete gear, and an actuator. The housing serves as the mounting base and foundation. The motor provides speed and torque, which are transmitted to the actuator via the multi-stage reduction mechanism, worm gear, worm, and incomplete gear. The actuator employs either a first structure or a second structure. In the first structure, the actuator includes a rack and a first spring, which, through the transmission of the incomplete gear and rack, causes the rack to extend and retract relative to the housing. In the second structure, the actuator includes a second gear, a winding shaft, a flexible connecting component, a second spring, and a weight impact block. The second spring causes a sudden change in the center of gravity of the weight impact block, generating vibration. This utility model's device has a compact structure, is lightweight, and has high transmission efficiency, meeting the needs of anti-icing and de-icing in actual operation and possessing strong practicality.
