Description

Technical Field

[0001] The invention relates to the technical field of anti-icing and deicing of overhead lines or railway contact networks, and in particular to an assembly structure suitable for an overhead line mechanical deicing device. Background Art

[0002] The problem of icing on overhead lines has always been one of the serious natural disasters in power systems at home and abroad. Mechanical deicing is a common means of preventing and removing ice from overhead lines. Invention [1] "Mechanical vibration deicing device" (CN201417921Y), Invention [2] "Elevated cable air blast vibration deicing device" (CN201549858U), Invention [3] "A mechanical vibration deicing device for overhead ground wire" (CN201247941Y), all of which work on the principle of driving the overhead line conductor or ground wire to vibrate through energy units and mechanical mechanisms to prevent and remove ice. In response to this, the state has also issued corresponding industry standards, "Technical Guidelines for the Use of Mechanical Vibration Deicing Devices for Overhead Transmission Lines and Ground Wires" (DL / T 1922-2018), which make relevant specifications for deicing operations and deicing processes. However, the energy sources of the power units of the above inventions all use pyrotechnics, which greatly restricts the use scenarios, scope of use and conditions of use. Moreover, during the deicing process, not only does the equipment need to be shut down, but also requires deep human participation, resulting in low operating efficiency. To this end, invention [4] "Anti-icing and de-icing device, spacer, system and anti-dance system based on sudden change of center of gravity" (CN115642555A), invention [5] "Anti-icing and de-icing device, spacer, support insulator and system for overhead line" (CN115483658B) and invention [6] "Anti-icing and de-icing device for split conductor of overhead line, sub-conductor spacer and system" (CN115632367A) and other related inventions have proposed a mechanical vibration de-icing device for overhead lines that uses a motor as a power unit and a spring as an energy storage and release device. This not only avoids the restrictions on the use of pyrotechnics, but also, this technical route basically does not require manual intervention, and to a certain extent, achieves de-icing without equipment power outage and less manual participation, thereby greatly improving the efficiency of anti-icing and de-icing. Summary of the Invention

[0003] Overhead line mechanical vibration de-icing devices are installed on the conductors or ground wires of overhead lines. This location not only makes the device difficult to install but also places high demands on lightweighting, requiring high mass and volume energy densities. This means producing a strong vibration effect with less mass and volume. Furthermore, the conductors and ground wires of overhead lines cannot directly provide energy, making it difficult to obtain the energy needed to vibrate the device. Typically, energy is collected from solar or wind energy, or from the magnetic field around the conductors through which current flows. This requires high transmission efficiency to generate sufficient vibration with relatively limited energy to meet the requirements of overhead line de-icing.

[0004] The inventions [4-6] mentioned in the background technology propose transmission components related to anti-icing and de-icing devices, such as motors, reduction mechanisms, clutch mechanisms, springs, and other transmission or energy storage and release components. These components need to be installed on the base. The base is actually the assembly structure of the entire anti-icing and de-icing device. Limited by the aforementioned objective conditions, it is particularly important to rationally design the assembly structure of the overhead line mechanical vibration de-icing device, especially the main structure. In addition to considering constraints such as energy density, lightweight, and energy utilization efficiency, it is also necessary to rationally select the components of the entire structure. Generally, a comprehensive balance is required in various aspects such as mechanical properties, working condition adaptation, process matching, and cost control. Among them, the design of the reduction gearbox and related transmission system is a highly systematic and iterative process. It is necessary to find the best balance between multiple dimensions such as functional performance indicators, transmission efficiency, structural strength and reliability, manufacturing feasibility, cost control, and maintenance convenience. It is necessary to avoid too few components and complex processing technology, and to avoid too many components and high assembly costs and complex installation procedures.

[0005] In the design of the main structure of the device in this application, the following factors must be considered: First, the overall main structure of the device must be determined, and the remaining supporting parts must be installed on this main structure. Second, the various components must maintain a certain connection relationship and be properly installed on the entire assembly structure to meet the requirements of force transmission and energy storage and release between different components. It must have a certain strength, high transmission efficiency, and overall reliability. Third, the overhead line mechanical de-icing device itself achieves overhead line anti-icing and de-icing through vibration. However, as a vibration source, some components of the device have a serious lack of vibration tolerance, such as the motor rotor, motor brushes, and related circuit components; another example is the reduction gears and reduction components of planetary or cycloid reduction systems. Because these are relatively delicate components, sufficient vibration damping protection must be provided for these components when designing the main structure of the device. Fourth, the reduction gearbox and related transmission system must ensure sufficient wall thickness and reasonably distributed reinforcement ribs, as well as the thickness and spacing of the rib plates, to ensure overall rigidity and local support rigidity of the reduction gearbox, while ensuring lightweight and transmission efficiency. Fifth, the assembly structure also needs to consider the installation process between different components. Ease of installation, a high degree of component standardization, and a relatively small number of overall types are essential to reduce costs and achieve overall lightweighting. Sixth, the individual assembly components must be simple to process, easy to manufacture, and low in cost. Taking all of these factors into consideration, the key issues that need to be addressed include how to design and optimize such an assembly structure, how to properly install, secure, and connect these components to better suit the actual operating environment, and how to improve de-icing efficiency and overall reliability. Considering the load spectrum, lightweighting, transmission efficiency, and shock absorption protection of key components, and balancing the trade-offs between different technical indicators such as overall lightweighting and transmission efficiency, are all key issues that need to be addressed.

[0006] In response to the above-mentioned constraints and various factors that require comprehensive compromise, this application focuses on taking optimization measures in the following aspects. First, the transmission components such as the worm wheel, worm, gear, incomplete gear, rack, and winding shaft are integrated into a reducer housing to form a reducer structural component, and this reducer structural component is used as the main structure of the entire device. Other related components are assembled on this main structure. This not only ensures the strength of the overall structure of the reducer structural component, reduces the mass and volume of the device, but also improves the overall transmission efficiency of the device. Second, the reducer housing is split along the axial direction of the worm, which is convenient for installing the worm wheel, worm and incomplete gear. Figure 17 In the related art shown, the motor, multi-stage reduction mechanism, worm wheel and worm share a first chamber 1A, and the incomplete gear, rack and spring share a second chamber 1D. Then the two chambers are fixedly connected and connected by a coupling. Figure 1、 Figure 8 It is aimed at Figure 17 The upgraded version of the improved solution. Figure 17 The split structure of the reduction gearbox designed in this application has a strong integrity, high transmission efficiency, a simple split structure, and a relatively simple installation process. Third, the first chamber where the worm wheel and worm are located shares a wall with the second chamber where the incomplete gear and rack are located (or the chamber where the incomplete gear and rack are located, or the chamber where the winding shaft is located). Under the same conditions, the weight is lighter, the strength and stiffness are better, the integrity of the reduction gearbox structural components is better, and the transmission efficiency is relatively high. Figure 17The reducer structural components of this application have obvious structural and performance advantages. Fourthly, the motor and the multi-stage reduction mechanism are the weak links with poor vibration tolerance of the entire device. There is a certain contradiction between improving the vibration resistance of the motor and improving the efficiency of the system transmission. To improve the transmission efficiency, a rigid transmission needs to be adopted. To improve the vibration resistance, a rigid connection cannot be adopted to avoid the vibration being transmitted to the weak links such as the motor and the multi-stage reduction mechanism through the rigid connection. In this application, by adding a flexible coupling, or an elastic coupling, or a flexible coupling (the rigid coupling or the flexible coupling adopts the definition and classification in the coupling classification of GB / T 12458-2017) between the output end of the motor structural component and the input end of the reduction box structural component, the vibration resistance of the motor and the multi-stage reduction mechanism is improved to a certain extent. At the same time, adding an elastic buffer pad between the motor structural component and the reduction box structural component also improves the vibration resistance to a certain extent. In fact, further shock absorption measures can be taken inside the motor structural component to more comprehensively protect the motor and the multi-stage reduction mechanism. Fifth, the appropriate use of rigid, flexible, or elastic transmission connections improves transmission efficiency while also ensuring overall device reliability and protecting vulnerable components with poor vibration resistance. Within each link of the entire device's transmission system, the front stage rotates at a higher speed, while the rear stage rotates at a lower speed. From front to rear, the system includes: a motor, a multi-stage reduction mechanism, a worm gear, a worm, incomplete gears, and energy storage and release mechanisms corresponding to the moving parts and springs. Generally speaking, rigid connections offer higher transmission efficiency, while flexible connections offer lower efficiency. However, rigid connections place higher demands on machining accuracy, assembly conditions, and the vibration resistance of related components. Therefore, the number and proper installation location of flexible or elastic couplings are crucial to the overall performance of the entire device. Installing a flexible or elastic coupling too close to the front stage will affect overall transmission efficiency. Installing a flexible or elastic coupling too close to the rear stage will result in excessive bulk, impacting the device's energy density. In addition, the specific location of the installation of the flexible coupling or elastic coupling also needs to be considered, which is a weak link in the protective device with poor vibration resistance. The present application reduces the number of flexible couplings or elastic couplings used through the integrated design of the reduction gearbox structural components, and reasonably arranges the transmission position of the flexible coupling or elastic coupling. Under the conditions of satisfying the overall performance such as processing accuracy, assembly conditions, and vibration resistance, the transmission efficiency is relatively high. Sixth, in view of the fact that the spring is prone to unnecessary bending in the axial direction after being subjected to force, the present application makes full use of existing structural components to constrain the deformation direction of the spring and avoid unnecessary energy loss. The spring housing of the spring structural component is used to form an outer slide cylinder, and the rack is used to form an inner slide rod. While constraining the deformation direction of the spring, no additional parts are added.

[0007] The present invention proposes an assembly structure applicable to, but not limited to, the base or housing of inventions [1-6]. The assembly structure is divided into three parts, namely, a reduction gearbox structural component, a motor structural component, and a spring structural component. The reduction gearbox structural component is used as the main structural component, which facilitates the installation of the worm gear, worm, and incomplete gear, which bear a large amount of force, in the reduction gearbox housing. The structure has good integrity, high transmission efficiency, and is light in weight. In addition, the housing is easy to seal, which is conducive to lubrication. The motor structural component is used to not only improve the vibration resistance of the device as a whole, but also facilitates the standardization of product components and the replacement of different models of motors. The spring structural component is used to separately use the spring housing as part of the assembly structure. This not only facilitates the selection of different springs, but also facilitates the selection of different spring housings according to the springs, facilitating the standardization of product components. The assembly structure in this application has a reasonable layout, compact connection, light weight, and high transmission efficiency. It better meets the actual operation requirements of the anti-icing and de-icing device of inventions [1-6] and has strong novelty, creativity, and practicality.

DETAILED DESCRIPTION

[0064] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0065] See Figures 1-11 , Figure 1 and Figure 8 The present invention provides an assembly structure suitable for an overhead line mechanical deicing device, which includes a motor structure component 1, a reduction gearbox structure component 2 and a spring structure component 3; the motor structure component 1 and the spring structure component 3 are fixedly mounted on the reduction gearbox structure component 2. Figure 3 The structure shown in is a schematic diagram of the exploded structure of the assembly structure of the present invention.

[0066] The motor structural component 1 includes a motor 11 and a motor housing 12. The motor 11 is installed in the motor housing 12, and the motor housing 12 is used to protect, fix and install the motor 11. The reduction gearbox structural component 2 includes a reduction gearbox housing 21, a worm gear 22, a worm 23 and an incomplete gear 24. The worm gear 22, worm 23 and incomplete gear 24 are all fixedly installed in the reduction gearbox housing 21. The worm gear 22 and worm 23 mesh with each other to form a worm gear mechanism, and the motor 11 is connected to the worm 23 in a transmission manner. The spring structural component 3 includes a spring 31, a spring housing 32 and a moving part. The spring 31 and the moving part are both arranged in the spring housing 32, and the incomplete gear 24 and the moving part are in transmission cooperation.

[0067] In this embodiment, the motor housing 12, the reduction gear housing 21 and the spring housing 32 are the supporting housing of the overhead line mechanical de-icing device, and the other actuating mechanisms of the overhead line mechanical de-icing device are fixedly installed in the supporting housing composed of the motor housing 12, the reduction gear housing 21 and the spring housing 32.

[0068] In other embodiments of the present invention, a multi-stage reduction mechanism 13 is provided in the motor housing 12, the input end of the multi-stage reduction mechanism 13 is connected to the output end of the motor 11, the output end of the multi-stage reduction mechanism 13 serves as the output end of the motor structural component 1, and the output end of the multi-stage reduction mechanism 13 is connected to the worm gear mechanism in the reduction box housing 21. The multi-stage reduction mechanism 13 can be in the form of multiple reduction mechanisms of the same type connected in series, or in the form of multiple reduction mechanisms of different types connected in series. Optionally, the multi-stage reduction mechanism 13 is composed of a cascade of multiple planetary gear reduction mechanisms, or a cascade of multiple cycloid reduction mechanisms. Furthermore, the multi-stage reduction mechanism 13 and the worm gear mechanism are connected via a coupling 14.

[0069] like Figure 4 As shown, the reducer housing 21 of the reducer structural component 2 is configured as a split structure along the axial direction of the worm 23 to facilitate the installation of the worm wheel 22, the worm 23, and the incomplete gear 24. That is, the reducer housing 21 is composed of two parts, namely a first reducer housing 211 and a second reducer housing 212. The first reducer housing 211 and the second reducer housing 212 are combined to form the reducer housing 21. The first reducer housing 211 is a one-piece structure, and the second reducer housing 212 is a one-piece structure. This allows the chamber where the worm wheel 22 and the worm 23 are located and the chamber where the incomplete gear 24 is located to share a portion of the wall. The first reducer housing 211 and the second reducer housing 212 have better integrity and higher structural strength. The straight line where the connecting seam between the first reducer housing 211 and the second reducer housing 212 is located is parallel to the axial direction of the worm 23 installed inside the reducer housing 21, and the two are in the same plane.

[0070] Furthermore, observation windows are respectively provided on the side walls of the first reduction gearbox housing 211 and the second reduction gearbox housing 212. The observation windows are covered by covers, and the covers are fixed to the reduction gearbox housing 21 by bolts. The purpose of providing the observation windows is to facilitate observation of the interior of the reduction gearbox housing 21, and also to facilitate installation of various parts installed inside the reduction gearbox housing 21 through the observation windows. Figure 1 The reference numeral 203 shown in the figure is the first cover plate. Figure 5 The reference numeral 204 shown in the figure is the second cover plate, and the first cover plate 203 and the second cover plate 204 in the figure are both configured as circular cover plates. At the same time, the first cover plate 203 and the second cover plate 204 can also be configured as any other suitable shapes.

[0071] like Figure 12 As shown, the tooth circumference of the incomplete gear 24 includes a toothed portion 242 and a smooth portion 241. The toothed portion 242 of the incomplete gear 24 is a section of teeth of a predetermined length arranged along the circumference of the incomplete gear 24. The portion of the incomplete gear 24 circumferentially unequipped with teeth is the smooth portion 241. The sum of the lengths of the toothed portion 242 and the smooth portion 241 is equal to the circumference of the incomplete gear 24. When the toothed portion 242 engages with the moving part, the incomplete gear 24 drives the moving part, causing the spring 31 to deform and accumulate elastic potential energy. When the smooth portion 241 engages with the moving part, the incomplete gear 24 and the moving part are disconnected from each other, and the spring 31 recovers its deformation and releases its elastic potential energy. The moving part, under the action of the elastic potential energy, moves and strikes the spring housing 32.

[0072] When the motor structure 1 and spring structure 3 are fixedly connected and installed with the reduction gearbox structure 2, the internal and external structures need to be connected simultaneously. Specifically, the internal connection includes: the multi-stage reduction mechanism 13 installed inside the motor structure 1 is connected to the worm 23 inside the reduction gearbox structure 2 through the coupling 14; the moving parts installed inside the spring structure 3 include two implementations:

[0073] When the moving part is a rack 34, the rack 34 arranged inside the spring structure component 3 is engaged with the incomplete gear 24 arranged in the reduction gear structure component 2 for transmission; when the moving part includes a winding shaft 25, a flexible connection component 26, a complete gear 27 and a heavy object impact block 33, the heavy object impact block 33 is connected to the winding shaft 25 set in the reduction gear structure component 2 through the flexible connection component 26.

[0074] External connections include: the motor housing 12 of the motor component 1 is fixedly connected to the reduction gearbox housing 21 of the reduction gearbox component 2, and the spring housing 32 of the spring component 3 is fixedly connected to the reduction gearbox housing 21 of the reduction gearbox component 2. Optionally, the motor housing 12 and the spring housing 32 are fixedly mounted on the same side of the reduction gearbox housing 22. This arrangement facilitates installation and improves the overall consistency of the device.

[0075] In other embodiments of the present invention, the motor housing 12 and the reduction gearbox housing 21, as well as the spring housing 31 and the reduction gearbox housing 21, are connected by means of protrusions. Specifically, when the motor housing 12 and the reduction gearbox housing 21 are fixedly connected, the location on the motor housing 12 where it connects to the reduction gearbox housing 21 is provided with a protrusion, and the location on the reduction gearbox housing 21 where it connects to the motor housing 12 is provided with a recessed structure that matches the protrusion.

Specifically, the motor structural component 1 and the reduction gear housing structural component 2 are fixedly connected by an elastic buffer pad to improve the ability of the motor 11 to withstand vibration and impact. The motor 11 and the motor housing 12 are fixedly connected by an elastic buffer pad, or the two are fixedly connected by filling glue and potting to improve the ability of the motor 11 to withstand vibration and impact.

[0077] As mentioned above, in the embodiments of the present invention, based on different mechanical de-icing principles for overhead lines, the moving components in the spring structure component 3 correspond to different implementation structures.

[0078] like Figure 2As shown, in one embodiment of the present invention, the moving component includes a rack 34. Specifically, the motor 11 in the motor structure 1 is used to provide power for the overhead line mechanical deicing device in this embodiment. The input end of the motor 11 is connected to a power source or other power generation equipment for power. After the external power source or external power generation equipment provides electrical energy to the motor 11, kinetic energy or torque is output through the motor 11. In this embodiment, after the motor housing 12 in the motor structure 1 and the reduction gear housing 21 in the reduction gear housing 2 are fixedly connected, the output end of the motor 11 disposed within the motor housing 12 is connected to the worm gear mechanism disposed in the reduction gear housing 21 to achieve kinetic energy or torque transmission. Specifically, the output end of the motor 11 is connected to the input end of the multi-stage reduction mechanism 13. The output end of the multi-stage reduction mechanism 13 is coaxially driven with the worm 23 in the worm gear mechanism through the coupling 14, capable of transmitting the power or torque output by the motor 11 to the worm 23 in the worm gear mechanism. The worm wheel 22 meshes with the worm 23, and the incomplete gear 24 is coaxially driven with the worm wheel 22, thereby transmitting power and torque to the incomplete gear 24, causing the incomplete gear 24 to begin rotating. The incomplete gear 24 is configured to mesh with the rack 34, causing the rack 34 to move in a specified direction. Optionally, the coupling 14 is a flexible coupling or an elastic coupling.

[0079] In the spring structure component 3, one end of the rack 34 is placed in the spring housing 32, and the other end passes through the reduction gearbox housing 21. One end of the spring 31 is connected to the rack 34, and the other end is connected to the spring housing 32, so that the spring 31 is restrained in the spring housing 32. Optionally, a base 38 can be fixedly mounted on the end of the rack 34 placed in the spring housing 32. The spring 31 is placed outside the rack 34, and one end of the spring 31 is fixedly connected to the base 38. A spring bracket 39 is provided. The spring bracket 39 has an annular structure and is placed outside the rack 34 and fixedly connected to the other end of the spring 31. By fixing the spring bracket 39 in the spring housing 32, the end of the spring 31 connected to the rack 34 can be fixed.

[0080] During actual operation, the incomplete gear 24 can drive the rack 34 and the spring 31. Specifically, through the meshing transmission of the tooth portion 242 of the incomplete gear 24 and the rack 34, the rack 34 is displaced relative to the spring housing 32. One end of the rack 34 is fixedly connected to one end of the spring 31 through the base 38, and the other end of the spring 31 is limited by being connected to the spring bracket 39. Therefore, when the rack 34 is displaced relative to the spring housing 32, the movement of the rack 34 drives the spring 31 to deform, and the spring 31 accumulates elastic potential energy due to the deformation.

[0081] When the incomplete gear 24 rotates until the smooth portion 241 mates with the rack 34, the incomplete gear 24 and rack 34 disengage from the transmission, and the rack 34 stops moving. The spring 31 is no longer under force and returns to its original shape, instantly releasing its elastic potential energy. As the spring 31 returns to its original shape, it drives the rack 34 to move rapidly, exerting a momentary thrust on the base 38, causing it to strike the bottom of the spring housing 32 at a constant speed. The outer side of the spring housing 32 is connected to an overhead line conductor or ground wire via an auxiliary connection component such as a wire clamp, causing the overhead transmission line or railway contact network to vibrate, achieving an anti-icing or de-icing effect.

[0082] like Figure 7 As shown, in this embodiment, to meet the needs of a large extension and retraction stroke of the spring 31, a first gear 201 and a second gear 202 are additionally provided in the reduction gearbox structural component 2. Specifically, the worm gear 22 and the incomplete gear 24 are configured to be coaxially driven, and the first gear 201 and the second gear 202 are configured to be coaxially driven, with the teeth portion 242 of the incomplete gear 24 meshing with the teeth of the second gear 202, and the teeth of the first gear 201 meshing with the teeth of the rack 34.

[0083] By controlling the speed and operating time of the motor 11, the motor 11 outputs power or torque, which is sequentially transmitted to the multi-stage reduction mechanism 13, the worm 23, the worm wheel 22, the partial gear 24, the second gear 202, and the first gear 201, and finally to the rack 34. The teeth of the first gear 201 mesh with the teeth of the rack 34, causing the rack 34 to move relative to the spring housing 32, thereby causing the spring 31 to deform and accumulate elastic potential energy.

[0084] As the incomplete gear 24 continues to rotate, until the smooth portion 241 of the incomplete gear 24 engages with the second gear 202, the incomplete gear 24 and the second gear 202 become disengaged. The incomplete gear 24 can no longer transmit power or torque to the second gear 202. At this point, no power or torque is transmitted to the rack 34. As the rack 34 disengages, the spring 31 recovers its deformation, releasing its elastic potential energy. As the spring 31 releases its elastic potential energy, it drives the rack 34 in the opposite direction, exerting a momentary thrust on the base 38, causing it to strike the bottom of the spring housing 32 at a certain speed. The outer side of the spring housing 32 is connected to an overhead line conductor or ground wire via an auxiliary connection component, such as a wire clamp. This causes the overhead transmission line or railway contact network to vibrate, achieving an anti-icing or de-icing effect.

[0085] Furthermore, a wear-resistant copper sleeve is provided between the rack 34 and the reduction gear housing 21. The wear-resistant copper sleeve is placed on the outside of the rack 34 and is fixedly provided on the reduction gear housing 21. When the rack 34 performs telescopic movement relative to the reduction gear housing 21, if the movement direction of the rack 34 deviates, it will be the first to come into contact with the wear-resistant copper sleeve. The wear-resistant copper sleeve can protect the rack 34, avoid wear of the rack 34, and avoid direct contact between the rack 34 and the reduction gear housing 21 to cause damage to the equipment. In an embodiment of the present invention, the wear-resistant copper sleeve is provided at a position close to the spring bracket 39, or the wear-resistant copper sleeve can be directly provided as the spring bracket 39. A wear-resistant pad is provided at the position where the spring 31 is connected to the spring bracket 39 to avoid wear caused by friction between the spring 31 and the spring bracket 39, and at the same time can play a shock-absorbing role.

[0086] In order to accumulate more elastic potential energy, the present invention achieves this goal by lengthening the length of the spring 31. Figure 5 As shown in the structure, Figure 5 The length of the spring 31 is increased, and the length of the spring housing for mounting the spring 31 is also increased accordingly. Figure 5 The length ratio of the spring structure component 3 to the motor structure component 1 is significantly greater than Figure 1 and Figure 3 The length ratio of the spring structural component 3 to the motor structural component 1 is specifically reflected in that the length of the spring housing 32 is increased while the length of the motor housing 12 remains unchanged.

[0087] In this embodiment, an outer slide is provided on the outside of the spring 31 to limit the deformation direction of the spring. Figure 2 In the structure shown, the spring housing 32 disposed outside the spring 31 serves as an outer slide cylinder.

[0088] In this embodiment, an inner slide bar is provided in the spring 31 to limit the deformation direction of the spring 31. Figure 6 In the structure shown, the rack 34 provided inside the spring 31 serves as the inner sliding rod.

[0089] like Figure 9 As shown, in another embodiment of the present invention, the moving parts include a winding shaft 25, a complete gear 27 and a heavy object impact block 33. In this embodiment, the winding shaft 25 and the complete gear 27 are arranged in the reduction gear housing 21. The gear teeth of the complete gear 27 are engaged with the tooth portion 242 of the incomplete gear 24, and the gear shaft of the complete gear 27 is coaxially connected to the winding shaft 25, and can be specifically set to coaxial transmission or integral molding. The winding shaft 25 is fixedly connected to one end of the flexible connecting part 26, and the other end of the flexible connecting part 26 is fixedly connected to the heavy object impact block 33. The spring 31 is arranged in the spring housing 32, and one end of the spring 31 is connected to the heavy object impact block 33, and the other end is connected to the spring housing 32.

[0090] The weight impact block 33 of the present invention is an object having a certain mass, and can be made of a high-density solid material with a certain hardness, elasticity, or toughness, which is conducive to improving the vibration effect generated by the device. The mass of the weight impact block 33 and the parameters of the spring 31 are comprehensively selected based on the vibration effect required by the device.

[0091] Specifically, the teeth of the complete gear 27 mesh with the teeth portion 242 of the incomplete gear 24, and the rotation of the incomplete gear 24 drives the complete gear 27 to rotate. The gear shaft of the complete gear 27 and the winding shaft 25 are coaxially driven or integrally formed, so that the winding shaft 25 can be driven to rotate by the complete gear 27, and the flexible connecting member 26 fixed to the shaft body of the winding shaft 25 begins to wind on the winding shaft 25. By controlling the rotation direction of the motor 11, the flexible connecting member 26 pulls the weight impact block 33 toward the winding shaft 25 during the winding process. The spring 31 is arranged between the weight impact block 33 and the spring bracket 39. The spring 31 moves with the weight impact block 33 toward the spring bracket 39. The spring bracket 39 is fixed in the spring housing 32 and limits the deformation of the spring. The tension of the flexible connecting member 26 causes the spring 31 to compress and deform between the weight impact block 33 and the spring bracket 39, thereby accumulating elastic potential energy.

[0092] When the incomplete gear 24 rotates to mate with the smooth portion 241 of the complete gear 27, the incomplete gear 24 and the complete gear 27 are disengaged from the transmission, and the winding shaft 25 and the heavy object impact block 33 lose drive. At this time, the compressed spring 31 begins to recover and instantly releases the stored elastic potential energy. The spring 31 exerts an instantaneous force on the heavy object impact block 33, which moves due to the elastic potential energy and impacts the spring housing 32. Specifically, the spring 31 pushes the heavy object impact block 33 away from the spring bracket 39 and impacts the base 38. The present invention connects the base 38 to the line of the overhead transmission line or the railway contact network. The released elastic potential energy acts on the base 38 to push the line of the overhead transmission line or the railway contact network, causing the line to vibrate, thereby achieving an anti-icing or de-icing effect.

[0093] like Figure 9As shown, a winding wheel 28 is fixedly provided on the winding shaft 25, and one end of the flexible connecting member 26 is fixed on the winding wheel 28. By rotating the winding shaft 25, the winding wheel 28 is driven to rotate, and the flexible connecting member 26 is wound onto the winding wheel 28. By providing the winding wheel 28, the winding position of the flexible connecting member 26 can be restricted to the winding wheel, reducing the shear force applied to the flexible connecting member 26 when it is wound on the winding shaft 25. At the same time, the winding of the flexible connecting member 26 on the winding wheel 28 increases the winding diameter of the flexible connecting member 26, reduces the required length of the flexible connecting member 26, and thus reduces the length of the spring housing 31, which is conducive to lightweighting of the entire device.

[0094] like Figure 10 As shown, two winding wheels 28 are symmetrically arranged on the axis of the winding shaft 25, namely the first winding wheel 281 and the second winding wheel 282, and two flexible connecting parts 26 are correspondingly arranged, namely the first flexible connecting part 261 and the second flexible connecting part 262, which have the same length; through the setting, one end of the first flexible connecting part 261 is fixed on the first winding wheel 281, and the other end is fixedly connected to the heavy object impact block 33; one end of the second flexible connecting part 262 is fixed on the second winding wheel 282, and the other end is fixedly connected to the heavy object impact block 33.

[0095] When the tooth portion 242 of the incomplete gear 24 meshes with the complete gear 27 for transmission, the winding shaft 25 starts to rotate after receiving the power or torque transmitted by the motor 11. When the winding shaft 25 rotates, it drives the first winding wheel 281 and the second winding wheel 282 to rotate accordingly, thereby causing the first flexible connection component 261 and the second flexible connection component 262 to be wound on the first winding wheel 281 and the second winding wheel 282 accordingly. During the winding process, the first flexible connection component 261 and the second flexible connection component 262 simultaneously pull the heavy object impact block 33 to move toward the winding shaft 25. While the heavy object impact block 33 moves, the spring 31 is compressed, causing the spring 31 to deform and accumulate elastic potential energy.

[0096] When the incomplete gear 24 rotates until the smooth portion 241 mates with the perfect gear 27, the incomplete gear 24 and the perfect gear 27 are disengaged. At this point, the winding shaft 25 can no longer receive the power or torque transmitted by the motor 11. The spring 31 is no longer under force and stops compressing, beginning to recover and release its elastic potential energy. As the spring 31 recovers and releases its elastic potential energy, it exerts an instantaneous thrust on the attached weight impact block 33. This instantaneous thrust causes the weight impact block 33 to move rapidly, striking the spring housing 32 and causing it to vibrate.

[0097] Furthermore, Figure 11As shown, a first winding wheel 281 and a second winding wheel 282 are disposed on the winding shaft 25, along with a flexible connecting member 26. The flexible connecting member 26 is symmetrically wound around the first and second winding wheels 281, 282. Perforations are provided on opposite sides of the first and second winding wheels 281, 282. The ends of the flexible connecting member 26 are connected to the weight impact block 33 in accordance with the aforementioned embodiment, with the flexible connecting member 26 passing through the perforations. This arrangement ensures that the pulling force exerted by the ends of the flexible connecting member 26 on the weight impact block 33 remains balanced during the winding process.

[0098] The solution disclosed in the present invention is an assembly structure suitable for a mechanical deicing device for overhead lines. After receiving electrical energy, the motor 11 outputs power or torque, and transmits the output power or torque along the multi-stage reduction mechanism 13, the worm 23, the worm wheel 22, and the incomplete gear 24 to the rack 34. When the tooth portion 242 of the incomplete gear 24 engages with the rack 34, the incomplete gear 24 drives the rack 34 to displace relative to the spring housing 32. During the displacement relative to the spring housing 32, the rack 34 causes the spring 31 to deform and accumulate elastic potential energy. When the incomplete gear 24 rotates until its smooth portion 241 engages with the rack 34, the incomplete gear 24 and the rack 34 are disconnected from each other, and the rack 34 no longer displaces relative to the spring housing 32. The spring 31 recovers its deformation and releases elastic potential energy. The elastic potential energy released by the spring 31 acts on the rack 34, causing the rack 34 to perform variable acceleration motion. When the rack 34 performs variable acceleration motion and contacts other components, the other components will vibrate. Based on this, Figure 13 and Figure 14 As shown, the present invention connects an ice-breaking head 81, which directly contacts an overhead line conductor or ground wire to break ice, to a spring housing 32. Specifically, an assembly structure further includes the ice-breaking head 81, which is connected to the spring housing 32. The assembly structure is placed near the overhead line conductor or ground wire to be de-iced, and the ice-breaking head 81 is brought into contact with the overhead line conductor or ground wire to be de-iced. When the spring 31 releases its elastic potential energy, the elastic potential energy drives the rack 34 to move and strike the spring housing 32, thereby driving the ice-breaking head 81, mounted on the spring housing 32, to strike the overhead line conductor or ground wire to be de-iced, thereby de-icing the wire.

[0099] in Figure 13 The bottom of the spring housing 32, which will serve as the outer slide, is opened so that the rack 34 can extend to the outside of the spring housing 32. At the same time, an ice-breaking head 81 is fixedly provided at the end of the rack 34 extending outside the spring housing 32. When the mechanical vibration mechanism vibrates, the ice-breaking head 81 directly hits the overhead line conductor or the ground wire, thereby achieving de-icing of the overhead line conductor or the ground wire. Figure 14 The ice breaking head 81 is fixedly mounted on the Figure 13 At the other end of the rack 34 opposite to the middle, by controlling the moving direction of the motor, the rack 34 moves into the spring housing 32 and compresses the spring 31. When the incomplete gear 24 and the rack 34 are out of transmission, the spring 31 releases the elastic potential energy, causing the rack 34 to perform variable acceleration movement in the direction away from the spring housing 32, driving the ice-breaking head 81 to directly hit the overhead line conductor or the ground wire, thereby realizing the de-icing action of the overhead line conductor or the ground wire.

[0100] Optionally, a limit rod 82 is provided on the end surface of the ice-breaking head 81 where it contacts the overhead line conductor or ground wire to limit contact between the ice-breaking head 81 and the overhead line conductor or ground wire. Furthermore, three limit rods 82 may be provided, evenly fixed on the ice-breaking end surface of the ice-breaking head 81. The ice-breaking end surface of the ice-breaking head 81 can be configured as a flat surface, a curved surface, or other suitable surface structure as required.

[0101] like Figure 13 and 14 As shown, when the ice-breaking head 81 is disposed at the first end 341 of the rack 34 , the ice-breaking head 81 is connected to the spring housing 32 via the rack 34 , and the first end 341 of the rack 34 passes through the reduction gear housing 21 and extends to the outside of the reduction gear housing 21 ;

[0102] When the ice-breaking head 81 is arranged at the second end 342 of the rack 34 , the ice-breaking head 81 is connected to the spring housing 32 through the rack 34 . A through hole 321 is provided at the bottom of the spring housing 32 , and the second end 342 of the rack 34 extends to the outside of the spring housing 32 through the through hole 321 .

[0103] like Figure 15 As shown, when the ice-breaking head 81 is disposed at the second end 342 of the rack 34 , the second end 342 of the rack 34 is fixedly connected to one end of the impact rod 343 , and the other end of the impact rod 343 is connected to the ice-breaking head 81 .

[0104] Optionally, the bottom of the spring housing 32 is connected to an extension sleeve 344;

[0105] The impact rod 343 includes an impact block 3431 and a connecting rod 3432. The impact block 3431 is disposed in the spring housing 32. One end of the connecting rod 3432 is fixedly connected to the impact block 3431, and the other end passes through the extension sleeve 344, 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 spring housing 32 through the impact rod 343 and the extension sleeve 344.

[0106] When the spring 31 releases its elastic potential energy, the elastic potential energy is converted into kinetic energy of the rack 34, causing the rack 34 to move toward the bottom of the spring housing 32 with variable acceleration, hitting the impact block 3431. The connecting rod 3432 connected to the impact block 3431 drives the ice-breaking head 81 to hit the overhead line conductor or ground wire to be de-iced to remove the ice.
